Patent Document 1: JP 2018-152174 A
A connector housing storage structure of the present disclosure is a connector housing storage structure for storing a connector housing constituting a connector member to be provided on an end part of a communication cable, and includes a first long body and a first reel, the first long body being wound on the first reel, wherein the first long body includes a plurality of connector housings and a first carrier linking the plurality of connector housings into one.
A connector cover storage structure of the present disclosure is a connector cover storage structure for storing a connector cover constituting a connector member to be provided on an end part of a communication cable, and includes a second long body and a second reel, the second long body being wound on the second reel, wherein the second long body includes a plurality of connector covers and a second carrier linking the plurality of connector covers into one.
A connector housing before being mounted on a communication cable is normally stored in a bag. That is, a plurality of connector housings are randomly packed into one bag. However, the connector housings may collide to be damaged in a container, such as during the transportation of the bag. Further, with a conventional storage structure, it is cumbersome to take out the connector housing from the bag such as when the connector housing is mounted on a communication cable. The same about the connector housing can be said also about the connector cover.
One object of the present disclosure is to provide a connector housing storage structure with which a connector housing is hardly damaged during storage and is easily handled, such as at the time of mounting on a communication cable. Another object of the present disclosure is to provide a connector cover storage structure with which a connector cover is hardly damaged during storage and is easily handled, such as at the time of mounting on a connector housing.
The connector housing storage structure of the present disclosure suppresses the damage of the connector housing during storage. Further, the connector housing storage structure of the present disclosure facilitates the handling of the connector housing, such as at the time of mounting on a connector housing.
The connector cover storage structure of the present disclosure suppresses the damage of the connector cover during storage. Further, the connector cover storage structure of the present disclosure facilitates the handling of the connector cover, such as at the time of mounting on a connector housing.
First, embodiments of the present disclosure are listed and described.
<1> A connector housing storage structure according to an embodiment is a connector housing storage structure for storing a connector housing constituting a connector member to be provided on an end part of a communication cable, and includes a first long body and a first reel, the first long body being wound on the first reel, wherein the first long body includes a plurality of connector housings and a first carrier linking the plurality of connector housings into one.
According to the connector housing storage structure of the embodiment, the connector housings do not fiercely collide with each other during the storage/transportation of the connector housings. This is because the connector housings are held by the first carrier. Therefore, the connector housing storage structure of the embodiment can suppress the damage of the connector housings, such as during storage.
According to the connector housing storage structure of the embodiment, the connector housings can be efficiently supplied to a work location where an operation of mounting the connector housing on the end part of the communication cable is performed. This is because the connector housings can be supplied to the work location only by feeding the first long body from the first reel toward the work location. Further, since the connector housings provided in the first long body are linked by the first carrier, the orientations of the connector housings to be supplied to the work location are aligned. Further, the connector housings linked to the first long body do not fall during a mounting operation of the connector housing. Therefore, the connector housing is easily mounted on the end part of the communication cable.
<2> As one form of the connector housing storage structure according to the embodiment, the plurality of connector housings are linked laterally side by side by the first carrier.
A connector housing is normally provided with an insertion hole into which a terminal is inserted. A direction along an axial direction of that insertion hole is a longitudinal direction of the connector housing, and a direction orthogonal to the longitudinal direction is a lateral direction. If the connector housings are arranged laterally side by side in the first long body, the insertion holes for the insertion of the terminals are open in a width direction of the first long body. Therefore, as described in embodiments later, the terminals can be successively inserted into the connector housings without cutting the connector housings off from the first long body.
<3> As one form of the connector housing storage structure according to the embodiment, each of the plurality of connector housings includes a terminal held inside.
If the terminal is held in the connector housing in advance, the damage of the terminal can be suppressed when the connector housing is mounted on the end part of the communication cable. By storing the terminal in the connector housing, the terminal is less likely to be damaged than in the case where a plurality of terminals are stored in one container.
Further, if the terminal is held in the connector housing in advance, an operation of mounting the connector member on the end part of the communication cable is facilitated. In this operation, the first long body is fed from the first reel and the tip of the communication cable is inserted into the terminal of each connector housing provided in the first long body. Here, since the connector housings are linked by the first carrier, the orientations of the connector housings to be successively supplied to the work location are aligned. Further, the connector housings linked to the first long body do not fall and the terminals held in the connector housings also do not fall. Therefore, the tip of the communication cable is easily inserted into the terminal of the connector housing.
<4> As one form of the connector housing storage structure described in <3> above, the terminal includes a wire barrel, and each of the plurality of connector housings includes a through hole provided at a position where the wire barrel is arranged.
The wire barrel is connected to a conductor of the communication cable, for example, by crimping. The through hole formed in the connector housing functions as a work space into which a tool or the like is inserted in connecting the wire barrel and the conductor. Therefore, even if the terminal is held in each connector housing provided in the first long body in advance, an operation of connecting that terminal and the conductor of the communication cable is easily performed.
<5> As one form of the connector housing storage structure described in <3> or <4> above, the terminal includes an engaging claw, and each of the plurality of connector housings includes an engaging recess to be locked by the engaging claw.
The terminal needs to be fixed to the connector member. If the terminal is formed with the engaging claw and the connector member is formed with the engaging recess corresponding to the engaging claw, the terminal and the connector member are firmly fixed.
Further, by providing the engaging claw having a more complicated shape than the engaging recess on the side of the terminal, the configuration of the connector member is simplified. Therefore, the connector member can be reduced in size by forming the terminal with the engaging claw.
<6> A connector cover storage structure according to the embodiment is a connector cover storage structure for storing a connector cover constituting a connector member to be provided on an end part of a communication cable and includes a second long body and a second reel, the second long body being wound on the second reel, wherein the second long body includes a plurality of connector covers and a second carrier linking the plurality of connector covers into one.
According to the connector cover storage structure of the embodiment, the connector covers do not fiercely collide with each other during the storage/transportation of the connector covers. This is because the connector covers are held by the second carrier. Therefore, the connector cover storage structure of the embodiment can suppress the damage of the connector covers, such as during storage.
According to the connector cover storage structure of the embodiment, the connector covers can be efficiently supplied to the work location. This is because the connector covers can be supplied to the work location only by feeding the second long body from the second reel toward the work location. Further, since the connector covers provided in the second long body are linked by the second carrier, the orientations of the connector covers to be supplied to the work location are aligned. Therefore, the connector cover is easily mounted on the connector housing.
Hereinafter, specific examples of a connector housing storage structure and a connector cover storage structure according to embodiments of the present disclosure are described on the basis of the drawings. In figures, the same reference signs denote the same components. Note that the present invention is not limited to these illustrations and is intended to be represented by claims and include all changes in the scope of claims and in the meaning and scope of equivalents.
Prior to the description of the connector housing storage structure and the connector cover storage structure of this example, a communication cable with connector in which a connector housing and a connector cover are used is described on the basis of
<Communication Cable with Connector>
A communication cable with connector 9 shown in
Communication Cable
The communication cable 8 is a twisted pair cable satisfying Ethernet (registered trademark) standards. The twisted pair cable is suitable for differential communication less susceptible to noise.
The communication cable 8 includes two twisted wires 8A, 8B. The wire 8A, 8B includes a conductor 80 and a conductor insulation layer 81 for covering the outer periphery of the conductor 80. The two twisted wires 8A, 8B are gathered into one by an interposed insulation layer 82. The communication cable 8 further includes a shielding layer 83 provided on the outer periphery of the interposed insulation layer 82 and a sheath 84 for covering the outer periphery of the shielding layer 83. The shielding layer 83 is for shielding electromagnetic waves and, for example, formed by a braided wire made of aluminum alloy. On the other hand, the sheath 24 is made of insulating resin such as polyvinyl chloride or polyethylene.
Terminal
The terminal of this example is a female terminal. The terminal 6 may be a male terminal. The terminal 6 includes a wire barrel 62 for gripping the conductor 80 of the communication cable 8. Although the wire barrel 62 is shown in an open state in
Connector Member
The connector member 3 of this example constituting the connector module 90 includes a connector housing 4 and a connector cover 5. Both the connector housing 4 and the connector cover 5 are made of insulating resin such as polyethylene. In this example, the connector housing 4 and the connector cover 5 are respectively stored by a connector housing storage structure 1 shown in
<<Connector Housing Storage Structure>>
The connector housing storage structure 1 shown in
First Reel
First, the configuration of the first reel 12 is described. The first reel 12 includes a winding drum 12D and two disk-shaped plates 12P, 12P. One plate 12P is arranged on one end side in an axial direction of the winding drum 12D, and the other plate 12P is arranged on the other end side in the axial direction of the winding drum 12D. The first long body 10 is wound on the winding drum 12D several turns and stored in a space between the two plates 12P, 12P. A reel hole 12H is provided in a center of the winding drum 12D. Thus, the first reel 12 is configured to be rotatable about a rotary shaft inserted into the reel hole 12H.
First Long Body
As shown in
The first long body 10 of this example is fabricated by linking a plurality of resin molded bodies serving as molding units. A state where two resin molded bodies are integrated is shown in
In the case of linking the two resin molded bodies described above, the resin molded body on a left side in
Connector Housing
The connector housing 4 includes a connector tube portion 40 (
The connector tube portion 40 includes a pair of insertion holes 4h (see also
The base portion 41 is further provided with a housing-side engaging portion 45 and a through hole 42 (
First Carrier
The first carrier 11 is configured by connecting the aforementioned frame pieces 11a, 11b, 11c, 11d and 11e, which are resin molded bodies. In this example, the frame piece 11d is a runner, and the runner 11d includes a gate 11g and an unillustrated sprue. The number of the gates 11g is appropriately selected depending on molding conditions.
The frame pieces 11a, 11b of the first carrier 11 include a plurality of reinforcing portions 11f projecting in a thickness direction thereof. The reinforcing portions 11f are plate-like pieces extending along the extending direction of the first long body 10. Excessive bending of the frame pieces 11a, 11b is suppressed by the reinforcing portions 11f. Further, the reinforcing portions 11f function to ensure a distance between different turns when the first long body 10 is wound on the first reel 12 (
According to the connector housing storage structure 1 of this example, the connector housings 4 do not fiercely collide with each other during the storage/transportation of the connector housings 4. This is because the connector housings 4 are held by the first carrier 11. Therefore, the connector housing storage structure 1 can suppress the damage of the connector housings 4, such as during storage.
According to the connector housing storage structure 1 of this example, the connector housings 4 can be efficiently supplied to a work location where the connector housing 4 is mounted on the end part of the communication cable 8 (
<<Connector Cover Storage Structure>>

As shown in
Second Reel
A basic configuration of the second reel 22 is the same as that of the first reel 12 of
Second Long Body
As shown in
Connector Cover
The connector cover 5 is a member for covering an opening of the base portion 41 in the connector housing 4 shown in
Second Carrier
The second carrier 21 includes sprues (not shown) and gates 21g in addition to the aforementioned frame pieces 21a, 21b, 21c, 21d and 21e. Further, the frame pieces 21a, 21b may be provided with a plurality of unillustrated reinforcing portions. The reinforcing portions have the same function as the reinforcing portions 11f of the first carrier 11 (
According to the connector cover storage structure 2 of this example, the connector covers 5 do not fiercely collide with each other during the storage/transportation of the connector covers 5. This is because the connector covers 5 are held by the second carriers 21. Therefore, the connector cover storage structure 2 of this embodiment can suppress the damage of the connector covers 5, such as during storage.
According to the connector cover storage structure 2 of this example, the connector covers 5 can be efficiently supplied to the work location. This is because the connector covers 5 can be supplied to the work location only by feeding the second long body 20 from the second reel 22 to the work location. Further, since the connector covers 5 provided in the second long body 20 are linked by the second carriers 21, the orientations of the connector covers 5 to be supplied to the work location are aligned. Therefore, the connector cover 5 is easily mounted on the connector housing 4.
<<Mounting Procedure of Connector Module on Communication Cable>>
A mounting procedure of the connector module 90 on the communication cable 8 (
As shown in
The terminals 6 are preferably supplied for a step shown in
Here, the configuration of the terminal 6 of this example is described on the basis of
The tubular portion 6A includes a leaf spring portion 60 for pressing the outer peripheral surface of the male terminal inserted into the terminal hole 6h. An outer part of this leaf spring portion 60 is exposed on the outer periphery of the tubular portion 6A. As shown in
A pressing portion 61 recessed toward the inside of the tubular portion 6A is provided on a surface of the tubular portion 6A opposite to the leaf spring portion 60. The pressing portion 61 presses the male terminal accommodated into the tubular portion 6A toward the leaf spring portion 60. As a result, the contact of the male terminal and the leaf spring portion 60 is reliably ensured. The pressing portion 61 of this example is also exposed on the outer periphery of the tubular portion 6A. Since nothing covers the pressing portion 61 from outside, the pressing portion 61 can be simultaneously formed when the tubular portion 6A is press-molded.
The connecting portion 6B is a part to be electrically connected to the conductor 80 (
The terminal 6 includes the engaging claw 63 to be engaged with the engaging recess 43 of the connector member 3 (
A thickness of each part of the terminal 6 is preferably 0.15 mm or less. If the thickness of each part of the terminal 6 is 0.15 mm or less, the terminal 6 is easily reduced in size. Further, the thickness of each part of the terminal 6 is preferably 0.05 mm or more. If this thickness is 0.05 mm or more, the strength of the terminal 6 is ensured. A more preferable thickness of each part of the terminal 6 is 0.075 mm or more and 0.13 mm or less. An even more preferable thickness of each part of the terminal 6 is 0.080 mm or more and 0.10 mm or less. The thickness mentioned here does not include a thickness of an edge formed by bending the plate material constituting the terminal 6.
The terminal 6 is made of a material excellent in conductivity. Here, the terminal 6 includes no protecting portion for covering the outer periphery of the leaf spring portion 60 unlike conventional female terminals. Thus, the terminal 6 of this example is preferably made of a material excellent in strength. An example of the material excellent in conductivity and strength is stainless steel. Stainless steels preferable for the terminal 6 of this example are, for example, 1.4372, 1.4373, 1.4310, 1.4318, 1.4305, 1.4307, 1.4306, 1.4311, 1.4303, 1.4401, 1.4436, 1.4404, 1.4432, 1.4435, 1.4406, 1.4429, 1.4571, 1.4438, 1.4434, 1.4439, 1.4539, 1.4541, 1.4550, 1.4587, 1.4381, 1.4462, 1.4507 and 1.4002 in European standards. Among these, 1.4310 and 1.4318 are, for example, preferable in terms of conductivity and strength. The surface of the terminal 6 is preferably plated with a material excellent in conductivity. A plating material is, for example, tin (Sn) or silver (Ag).
The terminal 6 configured as described above has a very simple configuration. Particularly, since the terminal 6 has no configuration for covering the leaf spring portion 60 and the pressing portion 61 from outside, the leaf spring portion 60 and the pressing portion 61 can be simultaneously fabricated when the tubular portion 6A is press-molded. Accordingly, the terminal 6 of this example can be more easily fabricated than conventional female terminals. As shown in
Next, the procedure of mounting the connector member 3 on the end part of the communication cable 8 is described with reference to
The end parts of the communication cables 8 are successively inserted into the connector housings 4. Accordingly, the connector housings 4 are efficiently mounted on the end parts of the communication cables 8. After the end part of the communication cable 8 is inserted into the connector housing 4, the wire barrels 62 of the terminals 6 and the conductors 80 of the communication cable 8 are connected.
A mounting tool 7 shown in
In the case of crimping the wire barrels 62 to the conductors 80 (
The second long body 20 is fed from the second reel 22 to the above work location shown in
The mounting operation described above may be performed by a human or may be automatically performed by an industrial robot. In either case, the efficiency of the mounting operation is very excellent. This is because the connector housings 4 and the connector covers 5 are successively supplied from the storage structures 1, 2 of this example and the orientations of the connector housings 4 and the connector covers 5 are aligned.
In the first embodiment, the terminals and the conductors of the communication cable are connected after the terminals are inserted into the connector housing. In contrast, the terminals may be inserted into the connector housing after the terminals and conductors of the communication cable are connected.
