This application claims the priority of Japanese Patent Application Nos. 2015-212611, filed on Oct. 29, 2015 and 2015-235464, filed on Dec. 2, 2015, the contents of which is incorporated by reference in its entirety.
1. Technical Field
The present invention relates to a coaxial cable connector. More specifically, present invention relates to a coaxial cable connector comprising cut parts that are separated from the carrier, and to a coaxial cable connector equipped with a carrier linked to one or more coaxial cable connectors, and to a method for manufacturing a coaxial cable connector that includes at least a step of separating the outer conductor shell from the carrier linked by a carrier linkage part.
2. Background Art
In a conventional process for manufacturing a coaxial cable connector or other such connector, a connector carrier linked by a linking piece to the rear end of the outer conductor shell of the connector is on the same side as a housing carrier linked by a linking piece to the rear end of a terminal that is housed in or built into a housing by integral molding or the like. The connector carrier and housing carrier that are on the same side are each positioned, and assembly is performed to house an insulated housing in the outer conductor shell.
The rear end of the outer conductor shell here is the end to the rear with respect to the extension direction of a coaxial cable connected to the outer conductor shell, and similarly, the rear end of the terminal is the end to the rear with respect to the extension direction of the coaxial cable. The distal end of the outer conductor shell and the distal end of the terminal are the ends to the front with respect to the extension direction of the coaxial cable.
For example, with the connector discussed in Japanese Laid-Open Patent Application 2011-181518, a carrier (connector carrier) linked to the outer conductor shell of the connector via a linking piece is on the same side as a carrier (housing carrier) linked to a center contact built into the housing via a linking piece, and these carriers are positioned one over the other on the same side, and the housing is mounted in the outer conductor shell to complete the assembly.
Patent Document 1: Japanese Laid-Open Patent Application 2011-181518
As in the conventional example discussed above, in a typical process for manufacturing a coaxial cable connector or other such connector, since the connector carrier and the housing carrier are on the same side, the jigs (or mechanisms) for supporting the carriers have to be designed so as not to impede movement, through positioning of the jigs, etc. Since the design of the jigs that support the two carriers on the same side thus has to take into account the positional relation of the carriers, their movement range, and so forth, the structure of the jigs is more complicated than the structure of a jig that supports just one carrier.
Also, since the rear end of the outer conductor shell of the connector is linked to the connector carrier via a linking piece, the connector carrier impedes connection in the compression connection of a coaxial cable to the rear end portion of the outer conductor shell, so in the course of manufacturing a coaxial cable connector, before the coaxial cable is compression connected to the rear end portion of the outer conductor shell, the connector carrier is cut away from the rear end of the outer conductor shell, and a clamp or other such jig is required to clamp and fix the coaxial cable connector that has been separated from the connector carrier.
Accordingly, the apparatus for manufacturing the coaxial cable connector has a complicated structure that comprises this clamp or other such jig. Furthermore, compared to when the coaxial cable connector is linked to the connector carrier, since it is merely fixed with a clamp or other such jig, the fixing position of the coaxial cable connector can become unstable in the compression connection of the coaxial cable.
In view of this, there are provided a coaxial cable connector, a connector carrier-equipped coaxial cable connector, and a method for manufacturing a coaxial cable connector, configured such that, instead of linking the rear end of the outer conductor shell of the connector with a linking piece as in prior art, or in addition to linking the rear end of the outer conductor shell with a linking piece, the outer conductor shell and the connector carrier are linked by a carrier linkage part provided at the desired location closer to the distal end side than the crimper of the outer conductor shell constituting the coaxial cable connector, and the connector carrier is disposed on the distal end side of the outer conductor shell (that is, the opposite side from the housing carrier linked to the rear end of the terminals built into the insulated housing), which simplifies the configuration of the apparatus for manufacturing the coaxial cable connector, including the jigs or the like for supporting the carriers, and in the compression connection of the coaxial cable to the rear end portion of the coaxial cable connector, allows the fixing position of the coaxial cable connector to be stabilized while still linked to the connector carrier and the coaxial cable can be connected to the coaxial cable connector in this state, without cutting the coaxial cable connector away from the connector carrier.

In an embodiment of manufacturing a coaxial cable connector pertaining to the present invention, the crimper includes a covering crimper and an outer conductor crimper,
the outer conductor shell of the coaxial cable connector further comprises a core wire crimper, and
before the step of cutting away the connector carrier, there are provided:
a step of fitting the housing that supports the terminals into the outer conductor shell; and
a step of bending the core wire crimper extending from the edge portion of the outer conductor shell so that the core wire of the coaxial cable disposed in a core wire connector of the terminals is compressed and connected to the core wire connector by a core wire fixing component that is insulated and is located on the inside of the core wire crimper, and respectively crimping and fixing the outer conductor and the covering of the coaxial cable with the outer conductor crimper and the covering crimper provided to the rear end portion of the outer conductor shell.
In an embodiment of manufacturing a coaxial cable connector pertaining to the present invention, the crimper includes a covering crimper and an outer conductor crimper,
the outer conductor shell of the coaxial cable connector further comprises a core wire crimper, and
before the step of cutting away the connector carrier, there are provided:
a step of connecting the core wire of the coaxial cable to the core wire connector of the terminals supported in the housing;
a step of fitting the housing that supports the terminals, in which the core wire of the coaxial cable is wired to the core wire connector, into the outer conductor shell; and
a step of bending the core wire crimper extending from the edge portion of the outer conductor shell so that the housing that supports the terminals is fixed to the outer conductor shell, and crimping and fixing the outer conductor and the covering of the coaxial cable with the outer conductor crimper and the covering crimper provided to the rear end portion of the outer conductor shell.
In an embodiment of manufacturing a coaxial cable connector pertaining to the present invention, the crimper includes a covering crimper and an outer conductor crimper,
the outer conductor shell of the coaxial cable connector further comprises a core wire crimper, and
before the step of cutting away the connector carrier, there are provided:
a step of fitting an insulated housing that does not support any terminals;
a step of fitting terminals, in which the core wire of the coaxial cable is connected to the core wire connector, to the housing; and
a step of bending the core wire crimper extending from the edge portion of the outer conductor shell so that the housing that supports the terminals is fixed to the outer conductor shell, and crimping and fixing the outer conductor and the covering of the coaxial cable with the outer conductor crimper and the covering crimper provided to the rear end portion of the outer conductor shell.
Because the outer conductor shell and the connector carrier are linked by a carrier linkage part provided at a desired location on the edge portion between the core wire crimper used for fixing the core wire of the coaxial cable and the distal end of the outer conductor shell, and the connector carrier is disposed on the distal end side of the outer conductor shell, the connector carrier can be disposed on the opposite side from the housing carrier, so there is no need to take into account the movement range of the carriers, their positional relation, and so forth, and the configuration of the manufacturing apparatus, including jigs and so forth, can be simplified.
Also, in the compression connection of the coaxial cable to the rear end portion of the coaxial cable connector, since the coaxial cable connector is not cut away from the connector carrier, the fixing position of the coaxial cable connector is stabilized while still linked to the connector carrier, and the coaxial cable can be connected to the coaxial cable connector in this state. Consequently, the clamp or other such mechanism for clamping and fixing the coaxial cable connector can be eliminated. Furthermore, since the coaxial cable connector can be handled in a state in which it is linked to the connector carrier, inspection and other such steps can be carried out more easily after the connection of the coaxial cable.

The connector carrier 10 links the outer conductor shells 30 with carrier linkage parts 12 via linking pieces 11 that stick out so as to support the outer conductor shells 30. In manufacturing a coaxial cable connector, positioning pilots 13 that serve as references for positioning the outer conductor shells 30 can be provided as needed to the connector carrier 10. The positioning pilots 13 shown in
In the course of manufacturing a coaxial cable connector, the carrier linkage parts 12 are cut to separate the outer conductor shells 30 from the connector carrier 10. To make it easier to cut away the outer conductor shells 30 from the connector carrier 10, a half-cut, consisting of a cutout or other such notch made about half-way through, can be formed in the carrier linkage parts 12.
The housings 40 can be molded integrally so as to support the terminals, and the terminals are built into them, with the middle portion of the terminals covered. The housing carrier 20 links the terminals included in the housings 40 with carrier linking components 23 via linking pieces 24 extending so as to support the terminals included in the housings 40. That is, the housing carrier 20 can support the housings 40 by linking the rear ends of core wire connectors 22 provided on the rear end side of the terminals built into the housings 40 (that is, the side on which the coaxial cables are connected) with the carrier linking components 23 via the linking pieces 24.
The housing carrier 20 can be provided as needed with positioning pilots 25 that serve as a reference for positioning the housings 40 in the manufacture of a coaxial cable connector. The positioning pilots 25 shown in
In the coaxial cable connector manufacturing process, the terminals built into the housings 40 can be separated from the housing carrier 20 by cutting the carrier linking components 23. Just as with the carrier linkage parts 12 of the outer conductor shells 30, a half-cut, consisting of a cutout or other such notch made about half-way through, can be formed in the carrier linking components 23 to make it easier to cut away the terminals built into the housings 40 from the housing carrier 20.
The outer conductor shells 30 comprise on their distal end side (that is, on the distal end side of the coaxial cable) housing accommodation components 31 configured to accommodate the cylindrical bases 41 of the housings 40, and comprise on their rear end side crimpers (connecting components) 32 configured to connect the outer conductors and covers of the coaxial cables. Walls 33 that are perpendicular to the plane of the housing accommodation components 31 are provided to the edge portions of the outer conductor shells 30. The walls 33 can each be formed, for example, by perpendicularly bending the edge up to the position where a core wire crimper 36 extends from the distal end of the outer conductor shell 30.
Also, the outer conductor shells 30 comprise substantially cylindrical parts 34 that are configured to surround the cylindrical parts 43 of the housings 40, hold down the protrusions 44 protruding from the side faces of the cylindrical bases 41, and fix the housings 40. Bending parts 35 are provided to the distal end portions of the outer conductor shells 30, and constitute part of the cylindrical parts 34. In the process of manufacturing coaxial cable connectors, the bending parts 35 are bent perpendicular to the plane of the housing accommodation components 31, using protrusions 45 as a reference, and the cylindrical parts 34 that extend from both sides of the bending parts 35 are bent at the bending parts 35 so as to surround the cylindrical parts 43 of the housings 40.
The outer conductor shells 30 further comprise crimpers, for fixing a coaxial cable, at their rear end portion. These crimpers each include covering crimpers 38 and outer conductor crimpers 37. In addition to the covering crimpers 38 and the outer conductor crimpers 37, core wire crimpers 36 that extend from the walls 33 are provided to the edge portions in the middle of the outer conductor shells 30. The core wire crimpers 36 are configured to bend in a box shape at the walls 33, thereby indirectly compressing and connecting the core wires of the coaxial cable disposed in the core wire connectors 22 with core wire fixing components 46 of the housings 40 on the inside. The outer conductor crimpers 37 and the covering crimpers 38 used for fixing are provided to the rear end portions of the outer conductor shells 30. The outer conductor crimpers 37 are configured to directly crimp, in a cylindrical shape, the outer conductors of the coaxial cables disposed in the crimpers 32, and thereby fix them to the outer conductor shells 30. The covering crimpers 38 are configured to directly crimp, in a cylindrical shape, the coverings of the coaxial cables, and thereby fix them to the outer conductor shells 30. Raised springs 39 that are formed by cutting and lifting the flat portion in the center of the outer conductor shells 30 (that is, the flat portion sandwiched by the walls 33 from which the core wire crimpers 36 extend) are provided to these flat portions, and the raised springs 39 are configured to engage with the main body parts 42 of the housings 40.
The housings 40 comprise the cylindrical bases 41 on the distal end side of the coaxial cable connectors and comprise the main body parts 42 on the rear end side. The cylindrical bases 41 comprise the cylindrical parts 43 extending to the side that connects with a mating connector, and on the side faces comprise protrusions 44 and 45 extending perpendicularly to the cylindrical parts 43. The protrusions 44 are held down by the substantially cylindrical parts 34 of the outer conductor shells 30 in the course of manufacturing the coaxial cable connectors, allowing the cylindrical bases 41 placed in the housing accommodation components 31 to be fixed. The main body parts 42 comprise holes (not shown) configured so as to engage with the raised springs 39 of the outer conductor shells 30. When the housings 40 are put into the outer conductor shells 30, the main body parts 42 engage with the raised springs 39, allowing the housings 40 to be fixed.
The cylindrical parts 43 expose the contacts 21 of the terminals from the side that is connected to the mating connectors. The main body parts 42 on the rear end side of the housings 40 comprise the core wire fixing components 46 that expose the core wire connectors 22 of the terminals from the side where the core wires of the coaxial cables are connected and extend to the side where the core wires of the coaxial cables are connected. The core wire fixing components 46 are configured to extend from the edge portions of the main body parts 42, which are on both sides of the core wire connectors 22, and so that the core wire fixing components 46 are disposed on the inside of the core wire crimpers 36 when the housings 40 are put into the outer conductor shells 30.
As shown in
Consequently, there is no need to take into account the positional relation, movement range, and so forth of the connector carrier 10 or the housing carrier 20, and the configuration of the manufacturing apparatus, including jigs and so forth, can be simplified.
In the embodiment of the present invention shown in
In this process, the carrier-equipped coaxial cable connectors 50 can be manufactured in a state of being linked to the connector carrier 10, and a plurality of coaxial cable connectors 50 can be wound and shipped on a reel in a state of being linked (not cut away from the connector carrier 10).
Also, the sub-carrier 14 comprises support pieces 17 that extend through the side parts of the coaxial cable connectors 50, and flat supports 18 that spread out in a fan shape from the support pieces 17. The sub-carrier 14 is linked to the connector carrier 10 by the supports 18 via the support pieces 17. For example, the supports 18 of the sub-carrier 14 can link to the edges of the linking pieces 11 of the connector carrier 10 facing the supports 18. Because the supports 18 are fan shaped, they can support the connector carrier 10 (or the linking pieces 11) over a wider area, so in the manufacture of the coaxial cable connectors, there will be less variance in the outer conductor shells 30. That is, in the course of manufacturing the coaxial cable connectors, when the housings 40 are put into the outer conductor shells 30, the outer conductor shells 30 will be securely fixed by the supports 18, so assembly of the housings 40 can be carried out more easily. Cutting positions 19 are the positions that are cut when the sub-carrier 14 is separated from the connector carrier 10 and the coaxial cable connectors 50.
The steps for manufacturing a carrier-equipped coaxial cable connector shown in
This process allows for the manufacture of the carrier-equipped coaxial cable connectors 50 in a state of being linked to the connector carrier 10 and the sub-carrier 14, and just as with the embodiment shown in
The sub-carrier 14 can be removed by cutting the carrier linkage parts 16 and the cutting positions 19 from the carrier-equipped coaxial cable connectors 50 in a state of being linked to the connector carrier 10 and the sub-carrier 14, so as to obtain the carrier-equipped coaxial cable connectors 50 in a state of being linked to the connector carrier 10 as shown in
In another embodiment of the present invention shown in
In the coaxial cable connector manufacturing process pertaining to an embodiment of the present invention and shown in
Since the outer conductor shells 30 constituting the coaxial cable connectors 50 are still linked to the connector carrier 10, in the connection of the coaxial cables, the connector carrier 10 can be held down with a jig or the like to stabilize the fixing position of the coaxial cable connectors 50 linked to the connector carrier 10. Consequently, the clamps or other such mechanisms used for sandwiching and fixing the coaxial cable connectors themselves can be omitted. Also, as shown in
The coaxial cable connector 50 shown in
In the embodiment shown in
As shown in
Individual working examples of the present invention are not limited to independent working examples, and can be suitably combined with each other.
A method for manufacturing a coaxial cable connector and a connector carrier-equipped coaxial cable connector in which one or more of the coaxial cable connectors pertaining to the present invention are linked can be utilized in a coaxial cable connector manufacturing process, and the coaxial cable connector thus manufactured can be used in electrical signal transmission in compact electronic devices, etc.
