BACKGROUND OF THE INVENTION
Technical Field

The invention relates to connectors.

Background Art

Japanese Unexamined Patent Publication No. 2012-22929 (paragraph 0008 and FIGS. 10 and 11) discloses a conventional connector including a terminal, a body, and a shield case. The terminal is generally L-shaped and has first and second portions perpendicular to each other. The body is generally L-shaped and holds the terminal. The shield case is made of a stamped metal plate and has a tubular portion and a housing portion behind the tubular portion. The body is held by the tubular portion, the first portion of the terminal is disposed in the tubular portion, and the second portion of the terminal is disposed in the housing portion.

SUMMARY OF INVENTION

The housing portion of the shield case includes an upper plate contiguous at its rear end with a bent piece. The bent piece is bent substantially perpendicular to the upper plate to close a rear opening of the housing portion. The front opening of the housing portion opens to the front, however, adversely affecting electromagnetic compatibility (EMC) characteristics of the conventional connector.

It is an object of the invention to provide a connector with improved EMC characteristics.

A connector according to an aspect of the invention includes a shield case being electrically conductive, a body being electrically insulating and housed in the shield case, at least one terminal being held by the body and housed in the shield case, a shield cover being electrically conductive and provided separately from the shield case. The shield case includes a tubular portion extending in a first direction and a pair of walls. The walls are located on one side in the first direction relative to the tubular portion, face each other in a second direction, and extend to one side in a third direction. The first direction is the axial direction of the tubular portion. The second direction is substantially orthogonal to the first direction. The third direction crosses the first and second directions. The body includes a first portion and a second portion. The first portion extends in the first direction, is disposed in the tubular portion, and includes a basal portion positioned on the one side in the first direction relative to the tubular portion. The second portion extends to the one side in the third direction from the basal portion of the first portion and is disposed between the walls of the shield case.

The basal portion may include a first exposed portion exposed to one side in the third direction between the walls. In this case, the shield cover may preferably include a first cover portion disposed between the walls to cover at least part of the first exposed portion of the first portion of the body from the one side in the third direction.

In the connector of this aspect, the first exposed portion of the basal portion of the first portion of the body is exposed to the one side in the third direction between the walls of the shield case, but at least part of the first exposed portion is covered by the first cover portion from the one side in the third direction. This arrangement improves the EMC characteristics of the connector.

The shield cover may further include at least one first elastic arm provided at the first cover portion. The at least one first elastic arm may be in elastic contact with at least one of the tubular portion, one of the walls, or the other wall of the shield case.

In the connector of this aspect, the elastic contact of the at least one first elastic arm with at least one of the tubular portion, one of the walls, or the other wall of the shield case brings the shield cover into a stable electrical conduction with the shield case. The shield case and the shield cover thus serve to establish a stable ground line.

The second portion may include a second exposed portion exposed to the other side in the first direction between the walls. In this case, the shield cover may preferably include a second cover portion disposed between the walls to cover at least part of the second exposed portion of the second portion of the body from the other side in the first direction.

In the connector of this aspect, the second exposed portion of the second portion of the body is exposed to the other side in the first direction between the walls of the shield case, but at least part of the second exposed portion is covered by the second cover portion from the other side in the first direction. This arrangement improves the EMC characteristics of the connector.

The shield cover may further include at least one second elastic arm provided at the second cover portion. The or each second elastic arm may be in elastic contact with one of the walls.

In the connector of this aspect, the elastic contact of the or each second elastic arm with one of the walls of the shield case brings the shield cover into a stable electrical conduction with the shield case. The shield case and the shield cover thus serve to establish a stable ground line.

The pair of walls may include a first wall and a second wall. A plurality of the second elastic arms may be provided, including one second elastic arm and the other second elastic arm. The one second elastic arm may be inserted between the first wall and the second portion of the body. The other second elastic arm may be inserted between the second wall and the second portion of the body.

In the connector of this aspect, it is possible to insert the one second elastic arms between the first wall and the second portion of the body, and the other second elastic arm between the second wall and the second portion of the body, and also to cover the second exposed portion of the second portion of the body with the second cover portion. In other words, it is possible to almost simultaneously perform two steps of bringing the second elastic arms into elastic contact with the walls and covering the second exposed portion of the second portion of the body with the second cover portion.

The second portion of the body may be provided with a housing recess opening to the other side in the first direction and housing the second cover portion. In this case, the second exposed portion of the second portion may be the bottom of the housing recess. In the connector of this aspect, the second cover portion in is housed in the housing recess of the second portion and therefore resists falling off when covering the second exposed portion of the second portion.

The shield cover may further include at least one attaching portion located between the walls of the shield case. The or each attaching portion may be attached to the second portion of the body and/or one of the walls.

In the connector of this aspect, it is possible to dispose the first or second cover portion between the walls of the shield case, and also to attach the or each attaching portion to the second portion of the body and/or one of the walls. This arrangement facilitates attachment of the at least one attaching portion.

The at least one attaching portion is only required to be attached to at least one of the shield case or the body.

The at least one attaching portion may extend in the first direction. In this case, the or each attaching portion may be inserted between the second portion and one of the walls. The at least one attaching portion may alternatively be received in a receiving groove or a receiving hole provided in the second portion of the body, and may be attached to the second portion.

Each of the walls may be larger in dimension in the first direction than the second portion of the body.

The tubular portion may have a first end on one side in the first direction. The shield case may further include an extended portion. The extended portion may be shaped like a half tube having a generally semi-circular, generally semi-polygonal, generally arc-shaped, or generally U-shaped, cross-section taken along the third direction. The extended portion of the shield case may extend to the one side in the first direction from a portion on the other side in the third direction of the first end of the tubular portion and may include first and second ends respectively on one and the other sides in the second direction. The walls of the shield case may include a first wall and a second wall. The first wall may extend from the first end of the extended portion to the one side in the third direction, and the second wall may extend from the second end of the extended portion to the one side in the third direction.

The shield case may further include a blocking portion. The blocking portion may at least partly block a space inside the extended portion and a space between the first and second walls from the one side in the first direction.

In the connector of this aspect, the extended portion blocks the space between the walls from the other side in the third direction, and the blocking portion at least partly blocks the space inside the extended portion and the space between the walls from the one side in the first direction. This arrangement further improves the EMC characteristics of the connector.

The connector C includes a shield case 100 being electrically conductive. The shield case 100 may preferably be, but is not required to be, a pressed metal plate (see FIGS. 1A to 3B). The shield case 100 includes a tubular portion 110, an extended portion 120, and a pair of walls 130a and 130b.

The tubular portion 110 is a tube extending in Y-Y′ direction having a generally circular (as shown FIGS. 1A to 3B) or generally polygonal cross-section taken along the Z-Z′ direction. Accordingly, the longitudinal, or axial, direction of the tubular portion 110 is the Y-Y′ direction. The tubular portion 110 is open on its Y-direction side. The tubular portion 110 has a first end on the Y′-direction side. The first end is ring-shaped (e.g. generally circular or generally polygonal) and includes a portion on the Z-direction side and a portion on the Z′-direction side. The extended portion 120 extends in the Y′ direction from the Z-direction side of the first end of the tubular portion 110. The extended portion 120 has a shape conforming to the portion on the Z-direction side of the first end of the tubular portion 110. More particularly, the extended portion 120 is shaped like a half tube having a generally semi-circular (as shown FIGS. 1A to 3B), generally semi-polygonal, generally arc-shaped, or generally U-shaped, cross-section taken along the Z-Z′ direction. The extended portion 120 has an inner space, the Y-direction side of which communicates with a space inside the tubular portion 110, and the Y′-direction side of which is open to the outside. The extended portion 120 includes a first end 121 on the X-direction side, a second end 122 on the X′-direction side, and a third end on the Y′-direction side.

In this case, the housing recess 221 has a bottom serving as a second exposed portion 223 exposed to the Y-direction side and located between the walls 130a and 130b. Where the housing recess 221 is omitted, the face on the Y-direction side of the second portion 220 in itself serves as the second exposed portion 223 exposed to the Y-direction side and located between the walls 130a and 130b.

In either of arrangements (a) and (b), where the shield case 100 includes the blocking portion 140, the blocking portion 140 is disposed on the Y′-direction side relative to the lead portion 320.

The connector C further includes a shield cover 400 being electrically conductive. The shield cover 400 is provided separately from the shield case 100. The shield cover 400 is a pressed metal plate (see FIGS. 1A to 3B) or a cast metal plate.

The shield cover 400 includes at least one of a first cover portion 410 or a second cover portion 430. The first cover portion 410 is a plate extending in the Y-Y′ and X-X′ directions. The first cover portion 410 is disposed between the walls 130a and 130b and covers, from the Z′-direction side, at least part of the first exposed portion 212b of the first portion 210 of the body 200. The first cover portion 410 may cover the entire first exposed portion 212b of the first portion 210 of the body 200 from the Z′-direction side. The first cover portion 410 may be in contact with, or in opposing spaced relation to, the first exposed portion 212b. The first cover portion 410 may, but is not required to, have a shape conforming to the first exposed portion 212b. In FIGS. 1A to 3, the first cover portion 410 curves in an arc shape conforming to the first exposed portion 212b.

The shield cover 400 may be modified as follows. Where the shield cover 400 includes the first cover portion 410, it is possible to omit the at least one first elastic arm 420, the second cover portion 430, the second elastic arms 440, the coupling portion 450, and/or the attaching portions 460. Where the shield cover 400 includes the second cover portion 430, it is possible to omit the first cover portion 410, the at least one first elastic arm 420, the second elastic arms 440, the coupling portion 450, and/or the attaching portions 460. Where the shield cover 400 includes both the first cover portion 410 and the second cover portion 430 but not the coupling portion 450, it is preferable that the first cover portion 410 and the second cover portion 430 are provided separately from each other. Where the attaching portion 460 is omitted, the first cover portion 410 may be bonded, with an adhesive or the like, to the first exposed portion 212b of the first portion 210 of the body 200 or to the tubular portion 110 of the shield cover 400, and/or the second cover portion 430 may be bonded, with an adhesive or the like, to the second exposed portion 223 of the second portion 220 of the body 200 or to the walls 130a and 130b of the shield cover 400. Alternatively, the second cover portion 430 may be fittingly received in the housing recess 221 so as to be attached to the second portion 220 of the body 200.

The following discussion is directed to methods for manufacturing the connector C according to some of the aspects described above. First, the terminal 300 and the body 200 holding the terminal 300 are prepared. The shield case 100 is also prepared. The first portion 210 and the second portion 220 of the body 200 are placed into the shield case 100. More particularly, the first portion 210 is placed into the tubular portion 110, the extended portion 120, and (into the first space) between the first portions of the walls 130a and 130b of the shield case 100, while the second portion 220 is placed (into the second space) between the second portions the walls 130a and 130b of the shield case 100. As a result, the terminal 300 held by the body 200 is set into place. More particularly, depending on the aspect of the connector C, the portion on the Y-direction side of the contact portion 310 of the terminal 300 is disposed inside the tubular portion 110 of the shield case 100, and the portion on the Y′-direction side of the contact portion 310 and the lead portion 320 are disposed inside the extended portion 120 of the shield case 100 and into the space between the walls 130a and 130b; or alternatively, the entire contact portion 310 of the terminal 300 is disposed inside the tubular portion 110 of the shield case 100, and the lead portion 320 is disposed in the extended portion 120 of the shield case 100 and into the space between the walls 130a and 130b.

Where the shield case 100 includes the blocking portion 140, the blocking portion 140 is bent at an angle of approximately 90° with respect to the extended portion 120, or with respect to one of the walls 130a and 130b. As a result, the blocking portion 140 at least partly blocks the space inside the extended portion 120 and the space between the walls 130a and 130b from the Y′-direction side, and is disposed on the Y′-direction side relative to the lead portion 320. Alternatively, where the blocking portion 140 is provided separately from the shield case 100, the blocking portion 140 is attached to the shield case 100 so as to at least partly block the space inside the extended portion 120 and the space between the walls 130a and 130b from the Y′-direction side and to be disposed on the Y′-direction side relative to the lead portion 320. Where the shield case 100 includes the at least one abutment 150, the or each abutment 150 is bent at an angle of approximately 90° with respect to the corresponding wall of the shield case 100 so as to be brought into contact with the body 200. Such step of bending the at least one abutment 150, if included, may be performed before or after the step of bending or attaching the blocking portion 140.

The shield cover 400 is also prepared and attached to the shield case 100 or the body 200. For the purpose of description and not of limitation, the following alternative steps (i) to (iv) of attaching the shield cover 400 relate to only some of the above-described various aspects of the shield cover 400.

(i) Where the shield cover 400 prepared includes the second cover portion 430, the one and other second elastic arms 440 of configuration (A) described above, and the one and other attaching portions 460 of the configuration (a) or (b) described above: The one attaching portion 460 and the one second elastic arm 440 are inserted between the second portion 220 of the body 200 and the wall 130a from the Y-direction side, and the other attaching portion 460 and the other second elastic arm 440 are inserted between the second portion 220 of the body 200 and the wall 130b from the Y-direction side. The one attaching portion 460 inserted is fixed onto the end face on the X-direction side of the second portion 220 of the body 200 or onto the inner face of the wall 130a, and the other attaching portion 460 inserted is fixed onto the end face on the X′-direction side of the second portion 220 of the body 200 or onto the inner face of the wall 130b. Also, the one second elastic arms 440 inserted is brought into elastic contact with the inner face of the wall 130a from the X′-direction side, and the other second elastic arm 440 inserted is brought into elastic contact with the inner face of the wall 130b from the X-direction side. Upon the insertion of the attaching portions 460 and the second elastic arms 440, the second cover portion 430 is inserted between the walls 130a and 130b, and the second cover portion 430 is disposed so as to at least partly cover the second exposed portion 223 of the second portion 220 of the body 200 from the Y-direction side. Where the second portion 220 is provided with the housing recess 221, the second cover portion 430 is housed into the housing recess 221 from the Y-direction side so as to at least partly cover the second exposed portion 223.

(ii) Alternatively, where the shield cover 400 prepared includes the pair of attaching portions 460 of configuration (c) described above: It is preferable that the attaching portions 460 are inserted into the corresponding receiving holes in the second portion 220 of the body 200 when inserting the pair of second elastic arms 440.

(iii) Where the shield cover 400 includes the first cover portion 410 and the coupling portion 450 in addition to the second cover portion 430, the second elastic arms 440 of configuration (A), and the attaching portions 460 of one of configurations (a) to (c), but also: Upon insertion of the attaching portions 460 and the second elastic arms 440 as described above, the first cover portion 410 is inserted between the walls 130a and 130b so as to at least partly cover the first exposed portion 212b of the first portion 210 of the body 200 from the Z′-direction side.

(iv) Where the shield cover 400 includes the at least one first elastic arm 420 in addition to the second cover portion 430, the second elastic arms 440 of configuration (A), the attaching portions 460 of one of configurations (a) to (c), the first cover portion 410, and the coupling portion 450: when placing the first cover portion 410 so as to cover at least partly the first exposed portion 212b of the first portion 210 of the body 200, the at least one first elastic arm 420 is brought into elastic contact with at least one of the following portions of the shield case 100: the outer face of the tubular portion 110, the inner face of the wall 130a, and/or the inner face of the wall 130b.

The connector C described above provides at least the following technical features and effects.

(1) The connector C has improved EMC characteristics. The body 200 of the connector C is formed such that the first exposed portion 212b of the first portion 210 is exposed in the Z′-direction between the walls 130a and 130b, and that the second exposed portion 223 of the second portion 220 is exposed in the Y direction between the walls 130a and 130b. As such, where the shield case 100 of the connector C is made of a pressed metal plate, the shield case 100 by itself cannot cover the first exposed portion 212b nor the second exposed portion 223. This is because such covering would require modifying the shield case 100 such that parts of the walls 130a and 130b are cut and bent in order to cover the first exposed portion 212b, and that further parts of the walls 130a and 130b are cut and bent in order to also cover the second exposed portion 223, but such modifications would make it impossible to form the walls 130a and 130b having configurations as described above. On the other hand, the connector C obviates the need to partly cut and bend the walls 130a and 130b. More particularly, the connector C includes the shield cover 400 separately provided from the shield case 100, and the shield cover 400 includes at least one of the first cover portion 410 and the second cover portion 430. The first cover portion 410 can cover at least part of the first exposed portion 212b of the first portion 210 of the body 200 from the Z′-direction side, and/or the second cover portion 430 can cover at least part of the second exposed portion 223 of the second portion 220 of the body 200 from the Y-direction side. For the above reasons, it is possible to improve the EMC characteristics of the connector C.

(2) The connector C has improved communication characteristics, especially where the shield case 100 includes the tubular portion 110, the extended portion 120, the walls 130a and 130b, and the blocking portion 140, and where the shield cover 400 includes the first cover portion 410 and the second cover portion 430. This is because the shield case 100 and the shield cover 400 surround and cover the contact portion 310 and the lead portion 320 of the terminal 300 in a manner (2-1) or (2-2) as follows.

(2-1) Where the a portion on the Y-direction side of the contact portion 310 of the terminal 300 is disposed inside the tubular portion 110 of the shield case 100 and the portion on the Y′-direction side of the contact portion 310 and the lead portion 320 are disposed inside the extended portion 120 and between the walls 130a and 130b of the shield case 100, the shield case 100, the shield cover 400, and the terminal 300 are arranged as follows. The tubular portion 110 surrounds the portion on the Y-direction side of the contact portion 310 of the terminal 300; the extended portion 120 of the shield case 100 is disposed on the Z-direction side relative to the portion on the Y′-direction side of the contact portion 310 and the lead portion 320; the walls 130a and 130b of the shield case 100 are disposed respectively on the X- and X′-direction sides relative to the portion on the Y′-direction side of the contact portion 310 and the lead portion 320; the blocking portion 140 of the shield case 100 is disposed on the Y′-direction side relative to the lead portion 320; the first cover portion 410 of the shield cover 400 is disposed on the Z′-direction side relative to the portion on the Y′-direction side of the contact portion 310 of the terminal 300 and the horizontal portion of the lead portion 320; and the second cover portion 430 of the shield cover 400 is disposed on the Y-direction side relative to the vertical portion of the lead portion 320 of the contact portion 310 of the terminal 300.

(2-2) Where the entire contact portion 310 of the terminal 300 is disposed inside the tubular portion 110 of the shield case 100, and where the lead portion 320 of the terminal 300 is disposed inside the extended portion 120 and between the walls 130a and 130b of the shield case 100, the shield case 100, the shield cover 400, and the terminal 300 are arranged as follows. The tubular portion 110 of the shield case 100 surrounds the entire contact portion 310 of the terminal 300; the extended portion 120 of the shield case 100 is disposed on the Z-direction side relative to the lead portion 320; the walls 130a and 130b of the shield case 100 are disposed respectively on the X- and X′-direction sides relative to the lead portion 320; the blocking portion 140 of the shield case 100 is disposed on the Y′-direction side relative to the lead portion 320; the first cover portion 410 of the shield cover 400 is disposed on the Z′-direction side relative to the horizontal portion of the lead portion 320 of the terminal 300; and the second cover portion 430 of the shield cover 400 is disposed on the Y-direction side relative to the vertical portion of the lead portion 320 of the contact portion 310 of the terminal 300.

(3) The connector C serves to establish a stable grounding line, especially where the shield case 100 and the shield cover 400 are arranged as follows. Where the shield cover 400 includes the at least one first elastic arm 420 and/or the plurality of second elastic arms 440, the at least one first elastic arm 420 is in elastic contact with the tubular portion 110 of the shield case 100 and at least one of the walls 130a and 130b, and/or the second elastic arms 440 are in elastic contact with the walls 130a and 130b of the shield case 100. This arrangement stabilizes electrical conduction between the shield cover 400 and the shield case 100, so that the shield case 100 and the shield cover 400 serve to establish a stable ground line.

(4) The connector C is configured such that the shield cover 400 elastically contacts the shield case 100 in a manner (4-1) and/or (4-2) as follows.

(4-1) Where the shield cover 400 includes the first cover portion 410 and the at least one first elastic arm 420, the at least one first elastic arm 420 can be brought into elastic contact with the tubular portion 110 and at least one of the walls 130a and 130b when the first cover portion 410 is placed so as to cover at least part of the first exposed portion 212b of the first portion 210 of the body 200 (i.e. a portion of the body 200 on the Y′-direction side relative to the tubular portion 110).

(4-2) Where the shield cover 400 includes the second cover portion 430 and the plurality of second elastic arms 440, the second elastic arm 440 can be brought into elastic contact with the walls 130a and 130b of the shield case 100 when the second cover portion 430 is placed so as to cover at least part of the second exposed portion 223 of the second portion 220 of the body 200, between the walls 130a and 130b. Particularly where the second elastic arms 440 extends in the Y′ direction from the second cover portion 430, when the second elastic arms 440 are respectively inserted between the second portion 220 of the body 200 and the walls 130a and 130b, the second cover portion 430 is placed so as to cover at least part of the second exposed portion 223 of the second portion 220 of the body 200. Where the plurality of attaching portions 460 as well as the second elastic arms 440 extend in the Y′ direction from the second cover portion 430, when the second elastic arms 440 are respectively inserted between the second portion 220 of the body 200 and the walls 130a and 130b and the attaching portions 460 are respectively inserted between the second portion 220 of the body 200 and the walls 130a and 130b or into the receiving holes of the second portion 220 of the body 200, the second cover portion 430 is placed so as to cover at least part of the second exposed portion 223 of the second portion 220 of the body 200.

(5) Where the second portion 220 of the body 200 is provided with the housing recess 221, the second cover portion 430 of the shield cover 400 is housed in the housing recess 221. This arrangement eliminates or reduces the possibility that the shield cover 400 may become detached from between the walls 130a and 130b.

(6) The connector C is configured to be securely mounted on a circuit board for the following reason. The second portion 220 has a dimension in the Y-Y′ direction smaller than that of each of the walls 130a and 130b. In other words, each of the walls 130a and 130b has a dimension in the Y-Y′ direction larger than that of the second portion 220. This makes it possible to place the respective ends in the Z′ direction of the walls 130a and 130b on the circuit board and thereby securely mount the connector C on the circuit board.

The connector of the invention is not limited to the embodiments and their variants described above, but may be modified within the scope of the accompanying claims. Specific modification examples will be described below.

[0101] The body of the invention may include the first exposed portion 212b of the first portion 210 and the second exposed portion 223 of the second portion 220 as described above, but either the first exposed portion 212b or the second exposed portion 223 may be omitted. To omit the first exposed portion 212b, the first exposed portion 212b of the first portion 210 may be covered by the tubular portion 110, setting the dimension in the Y-Y′ direction of each of the walls 130a and 130b to be substantially the same as, or slightly larger than, the dimension in the Y-Y′ direction of the second portion 220 of the body 200. In this case, it is preferable to omit the first cover portion 410 of the shield cover 400. To omit the second exposed portion 223, the second exposed portion 223 of the second portion 220 may be covered by a blocking portion that is contiguous with one of the walls 130a and 130b and bent at an angle of approximately 90° with respect to the wall 130a or 130b. In this case, it is preferable to omit the second cover portion 430 of the shield cover 400.

The shield case of the invention may not be made of a pressed metal plate. For example, the shield case may be made of a cast metal plate. The shield case of the invention may not include the extended portion. In such modified shield case, the tubular portion may preferable be contiguous with the pair of walls.

The connector according to any of the above aspects may be housed in an external body having insulating properties. At least a part of the external body may be covered with an external shield being electrically conductive. It should be appreciated that the invention does not require the external body and the external shield.

The invention only requires at least one second elastic arm and/or at least one attaching portion. For example, where there is provided a single second elastic arm 440 extending in Y-Y′ direction, the second portion 220 of the body 200 may be provided with a single receiving groove to receive the second elastic arm 440. Alternatively, in place of the receiving groove, an interstice to receive the second elastic arm 440 may be provided between the wall 130a or 130b and the second portion 220 of the body 200. Where there is provided a single attaching portion 460 extending in Y-Y′ direction, the second portion 220 of the body 200 may be provided with a single receiving groove or receiving hole to receive the attaching portion 460. Alternatively, in place of the receiving groove or receiving hole, an interstice to receive the attaching portion 460 may be provided between the wall 130a or 130b and the second portion 220 of the body 200.

The connector of the invention includes at least one terminal, which is only required to be held by an electrically insulating body and housed in the shield case of any of the above aspects. Where a plurality of terminals is provided, the terminals may be configured such that, for example, the terminals are held by an electrically insulating body, that the contact portions of the terminals are disposed in the tubular portion of the shield case of any of the above aspects, and that the lead portions of the terminals are disposed between the walls of the shield case of any of the above aspects.

The connector of the invention may or may not be mounted on a circuit board. For example, the connector of the invention may be a plug connector with at least one terminal connected to a cable. In this case, it is possible to omit the at least one leg portion of the shield case.

It should be appreciated that the materials, the shapes, the dimensions, the number, the positions, etc. of the elements of the connector in the above-described embodiments and their variants are presented by way of example only and can be modified in any manner as long as the same functions can be fulfilled. The aspects and variants of the above-described embodiments can be combined in any possible manner. It should be noted that the first direction of the invention may be any direction in which the tubular portion of the shield case of the invention extends. The second direction of the invention may be any direction crossing the first direction. The third direction of the invention may be any direction crossing the first and second directions.

The present invention can include any combination of these various features or embodiments above and/or below as set-forth in sentences and/or paragraphs. Any combination of disclosed features herein is considered part of the present invention and no limitation is intended with respect to combinable features.

Other embodiments of the present invention will be apparent to those skilled in the art from consideration of the present specification and practice of the present invention disclosed herein. It is intended that the present specification and examples be considered as exemplary only with a true scope and spirit of the invention being indicated by the following claims and equivalents thereof.
