Description

  The present invention relates to a connector manufacturing method manufactured by connecting a communication cable to a housing and a connector manufactured by the connector manufacturing method.

  As a connector manufactured by connecting a communication cable to a connector housing, there are modular plugs or modular jacks of various shapes (for example, see Patent Document 1 or Patent Document 2).

  A conventional manufacturing technique for manufacturing the connector as described above will be described with reference to FIG. FIG. 11 is an explanatory diagram for explaining a conventional example. This example will be described using a modular plug as an example.

  As shown in FIG. 11, a conventional connector 100 is configured by integrally connecting a housing 101 and a communication cable 102 with a contact 103.

  When fixing the communication cable 102 to the housing 101, first, the plurality of insulation-coated wires 102a in the communication cable 102 are exposed from the outer skin 102c using a tool. Here, the length L of the insulation coated wire 102a is adjusted so that the tip of the insulation coated wire 102a contacts the contact portion 101a of the housing 101 tip and the outer skin 102c bites into the fixed protrusion 101b of the housing 101. Must. The length L is generally about 11 mm.

  Next, with the tip of the insulation-coated wire 102a of the communication cable 102 in contact with the contact portion 101a of the housing 101, the contact 103 inserted from the lower part of the housing 101 is directed toward the insulation-coated wire 102a. Crimp using the. Then, the nail | claw 103a of the front-end | tip of the contact 103 penetrates the insulation coating wire 102a, and pierces the core wire 102b which is a metal wire. As a result, the housing 101 and the communication cable 102 are fixed, and conduction between the core wire 102b and the contact 103 is achieved.

  On the other hand, there is a connector (modular plug or modular jack) manufactured by connecting a communication cable to a connector housing (for example, Patent Document 3).

  The standard for communication cables is determined according to the transmission speed. The current mainstream is category 5, but recently, category 6 communication cables with higher transmission speed have been used.

  The communication cable is formed by twisting (more) eight insulating coated wires and covering them with an outer cover. Here, if this twist is removed and the insulation-coated wire is linearly stretched, near-end crosstalk occurs at the stretched portion. For this reason, it is preferable to fix the twist as close as possible to the contact.

  As an example of a conventional method for manufacturing a connector, a method for manufacturing a modular plug 200 will be described with reference to FIG. FIG. 12 is a diagram for explaining the configuration and manufacturing process of a conventional modular plug 200. FIG.

  As shown in FIG. 12A, a conventional modular plug 200 for category 6 includes a plug housing 201, a load bar 202, a divider 203, a collar 204, and a boot 205. Among them, the load bar 202 and the divider 203 are used for surely positioning while guiding a plurality of insulation-coated wires in the category 6 communication cable to the tip of the plug housing 201 in order. These plug kits are used to manufacture communication cable terminals.

  First, as shown in FIG. 12B, the communication cable 206 is passed in advance through the boot 205 and the collar 204 having the through holes 205a.

  As shown in FIG. 12C, the outer sheath of the communication cable 206 is removed, and the eight insulation-coated wires 207 included in the communication cable 206 are exposed. Since the two insulation-coated wires 207 are twisted and gathered, the twists are removed. Then, insulating coating wires 207 having appropriate coating colors are encased in the plurality of grooves 203a formed in the divider 203, respectively. Thereby, the eight insulated wires 207 are arranged in an orderly manner.

  As shown in FIG. 12D, each of the eight insulation-coated wires 207 arranged in an orderly manner by the divider 203 is inserted into eight holes formed in the load bar 202, respectively.

  As shown in FIG. 12 (e), the load bar 202 and the divider 203 are fitted to each other and configured integrally. Note that the excess insulation-coated wire 207 protruding from the tip of the load bar 202 is cut with a tool.

  As shown in FIG. 12 (f), after the load bar 202, the divider 203, the collar 204 and the boot 205 are fitted together, the load bar 202 is finally pushed into the plug housing 201 and fixed. To do. Finally, a modular plug 200 is completed by pressing a contact (not shown) against the insulation-coated wire 207.

  As described above, when a connector for a category 6 communication cable is manufactured, a guide member (in this conventional example, load bar 202, divider 203 is used in order to guide the twisted insulation-insulated wire 207 while maintaining it close to the contact. )Is required. Thus, conventionally, a plurality of guide members have been required in addition to the housing. This tendency is the same for the modular jack into which the modular plug is fitted, and a special guide member is required to make the connector.

  Further, in Japanese Patent Application Laid-Open No. 2002-280130 (Patent Document 4), a plate contact is press-fitted so that a sharp tip of the plate contact penetrates an individual coating of the core wire and bites into a corresponding core wire. It has been proposed to electrically connect a contact and a conductor of a core wire and cut off a tip portion of the core wire protruding from the front end of the housing.

  Japanese Patent Laying-Open No. 2004-31130 (Patent Document 5) proposes a technique for holding each twisted pair wire up to the vicinity of the through hole without untwisting in order to reduce near-end crosstalk.

Japanese Unexamined Patent Publication No. 60-066542 Japanese Patent Application Laid-Open No. 07-105744 JP 2007-335395 A JP 2002-280130 A JP 2004-31130 A

  However, since the insulation-coated wires 102a included in the communication cable 102 shown in FIG. 11 are bundled in a plurality (eight in this example), the lengths of all the core wires 102b are not cut evenly. When the communication cable 102 is inserted into the housing 101, some core wires may not reach the contact portion 101a completely. In this state, when the contact 103 is inserted into the housing 101 from below, some of the claws 103a may not pierce the core wire 102b. In this case, since the continuity cannot be obtained, it becomes a problem. Therefore, the defective connector must be cut off and the work must be performed again with a new connector. The work of stripping the insulating coated wire 102a from the outer skin 102c by a predetermined length is mainly performed manually by the worker at the site, and therefore the working time and quality differ greatly depending on the skill level of the worker. There was a problem.

  In addition, when a plurality of guide members are used, the number of steps increases, and the connector manufacturing operation becomes complicated. Further, since the wiring of the category 6 insulation covered wire 207 shown in FIG. 12 is complicated, it is necessary to check whether the insulation covered wire 207 is properly incorporated even when a guide member is used. Since the confirmation work is performed every time the insulation-coated wire 207 is incorporated into the member, the confirmation work is also complicated.

  An object of the present invention is to obtain a connector with a stable quality that is easy to assemble.

  In order to achieve the above object, a connector manufacturing method of the present invention is a connector manufacturing method in which a communication cable is inserted into a housing and the communication cable and the housing are fixed by a contact, and the insulation inside the communication cable is provided. Inserting the covered wire into the holding through hole of the housing, the insulating covered wire holding step for holding the insulating covered wire, and the contact formed with the fixed claw and the cutting claw in the insulating covered wire direction, A connector manufacturing method comprising: a crimping fixing step in which the fixing claw abuts against a core wire inside the insulating coated wire by crimping with the coated wire, and the cutting claw cuts the insulating coated wire.

When the contact is pressure-bonded to the insulation-coated wire, the fixed claw contacts the core wire inside the insulation-coated wire, and the cutting claw cuts the insulation-coated wire, The connector is disposed at a position adjacent to the insulation-coated wire.

  According to a second configuration of the connector of the present invention, a lid portion that covers all of the plurality of holding through holes from the outside of the housing is formed at the tip of the housing. connector.

  A third configuration of the connector according to the present invention is the connector according to the first configuration, characterized in that a cutting claw of the contact is provided on the front end side of the contact in the communication cable direction.

  A fourth configuration of the connector according to the present invention is the connector according to the first configuration, wherein a cutting claw of the contact is provided at a central portion of the contact in the communication cable direction.

  A fifth configuration of the connector of the present invention is the connector according to the first configuration, characterized in that the cutting claw of the contact is twisted in a direction crossing the communication cable.

The connector of the 1st structure characterized by these.

  With the connector manufacturing method and the connector configuration as described above, the insulation coated wire of the communication cable is crimped by the contact in which the fixing claw and the cutting claw are formed in the insulation coated wire direction while being held in the holding through hole. Fixed. At this time, since the insulating covered wire reaches the holding through hole, the core wire in the insulating covered wire also reaches the holding through hole. Here, by crimping the contact with the insulation-coated wire, the fixing claw of the contact reliably contacts the core wire inside the insulation-coated wire. As a result, continuity is achieved, resulting in stable quality. Further, when the contact is crimped and fixed, the contact cutting claw cuts unnecessary insulation-coated wires. Then, since the labor for cutting can be saved, the assembling work becomes easy. As a result, it is possible to obtain a connector with a stable quality that is easy to assemble.

[First Embodiment]
A first embodiment of the present invention will be described with reference to the drawings.

(Configuration of connector 10)

  As shown in FIG. 1, a modular plug will be exemplified and described as the connector 10 of the present embodiment. The connector 10 includes a housing 11, a communication cable 12 fixed in the housing 11, and a contact 13 for coupling and fixing the housing 11 and the communication cable 12.

  As shown in FIGS. 1 and 2, the housing 11 is in the shape of a modular plug in this embodiment, and is shaped to fit with a modular jack (not shown). A plurality of holding through-holes 11a corresponding to the number of insulating coatings are formed on the distal end side of the housing 11 so that the distal end portion of the insulating coating of the communication cable 12 penetrates. In addition, a fixing projection 11b for fixing the outer cover 12c of the communication cable 12 is formed inside the housing 11. An insertion hole 11 c for inserting the communication cable 12 is formed on the rear end side of the housing 11. Further, a guide hole 11 d for holding the side portion of the contact 13 and guiding the contact 13 is formed at the lower end of the front end side of the housing 11.

  As shown in FIG. 1B, the communication cable 12 includes a plurality of (eight in this embodiment) insulation-coated wires 12a that perform communication, and a sheath 12c that protects the insulation-coated wires 12a. In addition, there is a metal core wire 12b inside the insulation coating wire 12a.

  The same number of contacts 13 as the number of holding through holes 11a are arranged in the guide holes 11d on the lower surface of the housing 11. As shown in FIGS. 9A, 10A, and 10B, the contact 13 of the present embodiment has a long cutting claw 13b formed by twisting in a direction crossing the communication cable 12, and the communication cable A fixing claw 13a that is provided on the distal end side in the 12 direction and penetrates the communication cable 12 and is electrically connected to the core wire 12b is provided on the base side in the communication cable 12 direction. In the fixed claw 13a, four claws 13a1 and 13a2 cut alternately from opposite sides are arranged in a staggered manner, the communication cable 12 is stably held between the staggered claws 13a1 and 13a2, and the fixed claw 13a is It pierces the communication cable 12 and conducts with the core wire 12b. The claw 13b is formed by staggering two claws 13b1 and 13b2 cut from opposite sides after the top end is cut into a V shape. The guide hole 11d of the housing 11 is provided with a wide guide hole 11k through which the cutting claw 13b can be inserted. As shown in FIG. 1B, the contact 13 is inserted through the guide holes 11d and 11k at the lower portion of the housing 11, and then the cutting claw 13b cuts the communication cable 12, and the fixed claw 13a is insulated. Stings against 12a. Thereby, the housing 11 and the communication cable 12 are fixed.

  The plurality of fixing claws 13a are formed in a staggered pattern when viewed from above, and are fixed to the communication cable 12 and conducted to the communication cable 12 by being pierced into the insulation coated wire 12a. On the other hand, the cutting claw 13b is located closest to the holding through-hole 11a. The cutting claw 13b of the contact 13 of the present embodiment is provided on the front end side of the contact 13 in the direction of the communication cable 12, and the cutting claw 13b of the contact 13 is formed by being twisted in a direction crossing the communication cable 12. . The cutting claw 13b is arranged so that the tip of the cutting claw 13b is positioned above the insulating coated wire 12a of the communication cable 12 when the contact 13 is inserted upward along the guide hole 11d. The length is longer than the fixed claw 13a. Thereby, the insulation covered wire 12a and the core wire 12b are cut as will be described later. In addition, it is preferable that the head of the cutting claw 13b is bent so as to intersect with the insulating coated wire 12a when viewed from above.

  Further, the contact 13 is made of a conductive member such as metal, and a part of the lower end of the contact 13 protrudes from the lower portion of the insertion hole 11 c of the housing 11. And since this protrusion part 13c1 becomes a terminal, if it connects with the core wire 12b, transmission of the information from the communication cable 12 to a modular jack will be attained.

(Manufacturing method of connector 10)
A method of manufacturing the connector 10 having the above configuration will be described with reference to FIG. FIG. 3 is a cross-sectional view for explaining the manufacturing procedure of the first embodiment.

  First, the communication cable 12 is inserted into the housing 11 as shown in FIG. Here, in the communication cable 12, the insulation covered wire 12a is exposed from the outer skin 12c using a tool. 3A shows a state in which a part of the contact 13 is inserted and held at the lower end in the front end direction of the housing 11, but the contact 13 is not necessarily held at this stage.

  Next, as shown in FIG. 3B, the communication cable 12 is further inserted from the insertion hole 11c. Then, at the distal end portion of the communication cable 12, the insulation covered wire 12a of the communication cable 12 is passed through the holding through hole 11a. Thereby, the insulation covered wire 12a is held in the holding through hole 11a (insulation covered wire holding stage).

  Then, as shown in FIG. 3C, the contact 13 is inserted upward toward the insulating coated wire 12a along the guide hole 11d. At the time of insertion, tools such as crimping pliers are used and the contacts 13 are crimped to the housing 11 by gripping these tools (crimp fixing stage).

  Then, the fixing protrusion 11b of the housing 11 bites into the outer skin 12c of the communication cable 12. As a result, the communication cable 12 is fixed to the housing 11.

  At this time, the fixing claw 13a of the contact 13 passes through the insulation covered wire 12a of the communication cable 12 and pierces and contacts the inner core wire 12b. Then, the core wire 12b inside the insulation-coated wire 12a and the metal contact 13 come into contact with each other, and the communication cable 12 and the contact 13 become conductive. On the other hand, at this time, the cutting claw 13b of the contact 13 intersects the insulating coated wire 12a passed through the holding through-hole 11a and moves upward, and the cutting claw 13b crosses the insulating coated wire 12a. Will move like so. Thereby, the insulation coating wire 12a is cut together with the core wire 12b (state of FIG. 3C).

  Thus, depending on the present embodiment, the insulation covered wire 12a is held at the front end of the housing 11, and the contact 13 guided by the lower end of the housing 11 is inserted into the insulation covered wire 12a. Thus, electrical connection between the core wire 12b and the contact 13 can be ensured. Further, the fixing operation of the insulation-coated wire 12a by the fixing claw 13a, the contact operation of the fixing claw 13a with the core wire, and the cutting operation of the insulating-coated wire 12a by the cutting claw 13b are performed simultaneously.

  As described above, according to the present embodiment, all of the plurality of insulation-coated wires 12a are once passed through the holding through holes 11a. As a result, the insulation-coated wire 12a can reliably reach the tip of the housing 11 (the portion having the holding through-hole 11a). Then, when the fixed claw 13a of the contact 13 is moved upward, the fixed claw 13a surely reaches the core wire 12b inside the insulation-coated wire 12a. As a result, it is no longer necessary to cut the insulation-coated wires uniformly in advance in order to ensure that all the insulation-coated wires reach the front end of the housing as in the prior art, thereby greatly reducing the manual labor burden on the operator. Can do. In addition, since the fixing claw reliably contacts the core wire inside the insulating coated wire, the quality of the connector is stabilized.

  In addition, when the contact 13 is provided with a cutting claw 13b, the contact 13 performs the operation of crimping and fixing the communication cable 12 to the housing 11, and at the same time, the insulation-coated wire passing through the holding through hole 11a. 12a can be cut. For this reason, it is not necessary to cut the insulation-coated wire again as in the prior art, and the assembling work is facilitated.

  As described above, the assembly operation is easy and stable by arranging and crimping the contact on which the fixing claw and the cutting claw are formed adjacent to the insulation coated wire 12a as in this embodiment. Can be obtained.

[Second Embodiment]
A second embodiment of the present invention will be described with reference to the drawings. Embodiments similar to those described above are denoted by the same reference numerals and description thereof is omitted. In the second embodiment, a modular plug will be described as an example.

(Configuration of connector 40)
First, the basic configuration of the connector 40 will be described with reference to FIG. 4A and 4B are diagrams illustrating the configuration of the modular plug connector 40, in which FIG. 4A is a perspective view and FIG. 4B is a cross-sectional view.

  As shown in FIG. 4, the connector 40 includes a housing 41, a communication cable 12 fixed to the housing 41, and a contact 13 that couples and fixes the housing 41 and the communication cable 12.

  The appearance of the housing 41 is in the shape of a modular plug, which is a shape that fits into a modular jack (not shown). A plurality of through-holes 41a corresponding to the number of insulation-coated wires 12a (eight in this embodiment) are formed on the distal end side of the housing 41 so that the distal end portion of the insulation-coated wire 12a of the communication cable 12 penetrates.

Similarly, seven guides 41b are disposed at the inner lower portion of the through hole 41a.

  A laterally wide lid portion 41c that covers all of the plurality of through holes 41a from the outside of the housing 41 is formed above the outside of the through hole 41a at the front end portion of the housing 41. The lid 41c is a plate-shaped member that is integrally formed with the housing 41. In the initial state, the lid 41c has a shape that protrudes outside in parallel to the through hole 41a above the through hole 41a, and thus covers the through hole 41a. Not. Here, the base portion of the lid portion 41c is configured to be thinner than the thickness of the lid portion 41c main body, and can be bent downward using the root portion as a hinge. When the lid portion 41c is bent downward, the entire through hole 41a is covered. The lid portion 41 c is inserted into a recess 41 n formed on the surface side of the holding through hole 41 a of the housing 41, and is mounted so that the surface of the lid portion 41 c is flush with the surface of the housing 41.

  Inside the housing 41, an insertion hole 41d for inserting the communication cable 12 from the rear end of the housing 41 is formed. An inclined portion 41e is formed continuously with the insertion hole 41d. The inclined portion 41e serves to smoothly guide the insulation-coated wire 12a of the communication cable 12 inserted from the rear end to the through hole 41a. A contact guide hole 41f for guiding the contact 13 serving as a terminal is formed in a lower portion of a portion between the inclined portion 41e and the through hole 41a. Here, as shown in FIG. 4B, in the present embodiment, an inclined portion 41e is formed immediately before the contact guide hole 41f, and the insertion hole 41d extends greatly to the rear end of the housing 41. For this reason, it is possible to guide the communication cable 12 to the distal end.

  As shown in FIG. 4A, in the communication cable 12, a plurality of (eight in this embodiment) insulation-coated wires 12a that perform communication are protected by an outer sheath 12c. Each insulation-coated wire 12a is color-coded according to the characteristics of each wire, and is formed by twisting two wires. There is a metal core wire 12b inside the insulation coated wire 12a.

  The contacts 13 are conductive members such as metal disposed in the contact guide holes 41f on the lower surface of the housing 41 in the same number as the number of holding through holes 41a. As shown in FIGS. 9 (b), 10 (c), and 10 (d), the contact 13 of the present embodiment has a long cutting claw 13b formed by being twisted in a direction crossing the communication cable 12, and the communication cable Fixing claws 13a that are provided at the center in the 12 direction and penetrate the communication cable 12 and are electrically connected to the core 12b are provided on both sides of the cutting claw 13b in the communication cable 12 direction. In the fixed claw 13a, four claws 13a1 and 13a2 cut alternately from opposite sides are arranged in a staggered manner, the communication cable 12 is stably held between the staggered claws 13a1 and 13a2, and the fixed claw 13a is It pierces the communication cable 12 and conducts with the core wire 12b. The claw 13b is formed by staggering two claws 13b1 and 13b2 cut from opposite sides after the top end is cut into a V shape. The contact guide hole 41f of the housing 41 is provided with a wide contact guide hole 41k through which the cutting claw 13b can be inserted. Then, after the contact 13 is inserted from the contact guide holes 41f and 41k in the lower part of the housing 41, the cutting claw 13b cuts the communication cable 12, and the fixed claw 13a is pierced into the insulation-coated wire 12a. Thereby, the housing 41 and the communication cable 12 are fixed.

  As shown in FIGS. 4 (b), 10 (c), and (d), the contact 13 of the present embodiment has a plurality of fixed claws 13a and a fixed portion at the center of the fixed claws 13a. A cutting claw 13b longer than the claw 13a is formed, and its lower end 13c is wider than the tip. This lower end 13c serves as a communication terminal. The cutting claw 13b of the contact 13 of this embodiment is provided at the center of the contact 13 in the direction of the communication cable 12, and the cutting claw 13b of the contact 13 is formed by being twisted in a direction crossing the communication cable 12. .

  The contact 13 is inserted from the contact guide hole 41f in the lower part of the housing 41, and is then crimped so that the cutting claw 13b cuts the communication cable 12, and the fixed claw 13a is pierced with the insulated coated wire 12a. Abut. As a result, the housing 41 and the communication cable 12 are fixed and become conductive. Then, the cutting claw 13b is cut so that the tip of the cutting claw 13b is positioned above the insulation-coated wire 12a of the communication cable 12 when the contact 13 is inserted upward along the contact guide hole 41f. The claw 13b is formed longer than the fixed claw 13a. Thereby, the insulation covered wire 12a and the core wire 12b are cut as will be described later.

(Manufacturing method of connector 40)
A method of manufacturing the connector 40 having the above configuration will be described with reference to FIG. FIG. 5 is a cross-sectional view for explaining the manufacturing procedure of the connector 40.

  First, the outer sheath 12c at the front end of the communication cable 12 is removed in advance to expose the insulation covered wire 12a. Then, only the distal end portion of the insulation-coated wire 12a is twisted by two insulation-coated wires 12a that are twisted together. The reason why only the tip portion is selected is that when the portion of the insulation-coated wire 12a is twisted and the portion that does not become a pair becomes long, there is a problem that near-end crosstalk occurs accordingly.

  As shown in FIG. 5A, the communication cable 12 is inserted into the housing 41 from the insertion hole 41d. Then, the eight insulation-coated wires 12a at the tip of the communication cable 12 are passed through the respective through holes 41a while guiding the side portions of the guides 41b <insulation-coated wire insertion step>. The presence of the guide 41b allows the operator to easily pass the insulating coated wire 12a through the through hole 41a. Here, the insulation coated wire 12a is penetrated to the outside through the through hole 41a. The arrangement of the insulation covered wires 12a in the housing 41 can be confirmed outside by taking out the insulation covered wires 12a from the through holes 41a. Then, the operator can confirm the arrangement of the insulation-coated wires 12a at a glance.

  After confirming whether the insulation-coated wires 12a are correctly arranged, as shown in FIG. 5A, the lower end 13c of the contact 13 is pushed upward toward the insulation-coated wire 12a using a tool such as crimping pliers. As a result, as shown in FIG. 5 (b), the fixed claws 13a bite into the coating of the insulation coated wire 12a, the contact 13 is crimped to the insulation coated wire 12a, and the insulation coated wire protruding out of the housing 41 is obtained. 12a is cut by the cutting claw 13b <crimp fixing step> <insulation coated wire cutting step>.

  As shown in FIG. 5 (b), the cutting claw 13b of each contact 13 cuts the communication cable 12, and the fixed claw 13a bites into the coating of the insulation coated wire 12a. Here, the upper side of the contact 13 is fixed to the insulating coated wire 12a, and the movement of the side of the contact 13 is restricted by the contact guide hole 41f. Reference numeral 41j denotes a relief hole for accommodating the long cutting claw 13b. Accordingly, the communication cable 12 is fixed to the housing 41. At this time, the insulation covered wire 12a and the core wire 12b are cut by the cutting claw 13b of the contact 13, and the fixed claw 13a passes through the insulation covered wire 12a of the communication cable 12 and pierces the inner core wire 12b. Then, the core wire 12b inside the insulation-coated wire 12a and the metal contact 13 come into contact with each other, and the communication cable 12 and the contact 13 become conductive.

  Finally, when the lid portion 41c is pressed from above, the lid portion 41c is bent at the base portion. Thereby, it is possible to prevent the distal end portion of the insulating coated wire 12a from being exposed to the outside, and to protect the distal end of the insulating coated wire 12a held in the through hole 41a. <Insulated coated wire protection step>.

  As described above, depending on the present embodiment, the connector 40 is formed by a member including only the housing 41, the communication cable 12, and the contact 13. For this reason, a special member is not required for guiding the insulation covered wires to the front end of the housing in a properly arranged state, such as a load bar and a divider that have been conventionally used. Therefore, a connector that is easier to manufacture can be provided. Further, since the number of members is reduced, various labors and resources can be saved.

  In addition, since the insulation covered wire 12a is once taken out from the through hole 41a in the manufacturing process, the operator can easily confirm the arrangement of the insulation covered wire 12a. When manufacturing a connector, it is important to arrange the insulation-coated wires accurately, but the conventional connector has a large number of members and confirms the wires inside the housing. Later, it was almost impossible to confirm the arrangement of the insulated wires. For this reason, there was a problem in the confirmation work of the arrangement | positioning of an insulation coating wire. According to the present embodiment, as described above, since the insulation-coated wire 12a comes out to the outside, the confirmation work becomes easy.

  Furthermore, this embodiment is also excellent in terms of certainty of conduction between the communication cable 12 and the contact 13. That is, according to the conventional configuration, it is a premise that the insulation-coated wire reaches the tip when the contact is crimped. However, this confirmation work is difficult because the insulated wire is in the housing and is held by the load bar. On the other hand, according to the present embodiment, since the insulating covered wire 12a passes through the through hole 41a, it is certain that at least the insulating covered wire 12a reaches the tip of the housing 41. For this reason, when the contact 13 is pressure-bonded to the communication cable 12, the contact 13 surely reaches the core wire 12b of the insulation-coated wire 12a. Accordingly, the communication cable 12 and the contact 13 can be reliably connected.

  Next, a modification of this embodiment will be described with reference to FIGS.

  In the embodiment shown in FIGS. 4 and 5, the lid portion 41 c is configured integrally with the housing 41, but is not limited thereto, and may be a separate body. Specifically, the one shown in FIG. 6 can be considered. 6A and 6B are explanatory views of a modified example of the lid portion of the present embodiment, in which FIG. 6A is a view using the claw cover member 51, FIG. 6B is a view using the hole cover member 52, and FIG. 6 is a view using a plate-like lid member 53.

The claw cover member 51 is inserted into a recess 41n formed on the surface side of the holding through hole 41a of the housing 41 so that the surface of the claw cover member 51 is flush with the surface of the housing 41. Installed.

  Further, as shown in FIG. 6 (b), a holding projection 41h is formed on both sides of the through hole 41a outside the front end of the housing 41, and a holed lid member 52 having a hole 52a into which the holding projection 41h is fitted. It is good also as a cover part. The holed lid member 52 is also inserted into a recess 41n formed on the surface side of the holding through hole 41a of the housing 41 so that the surface of the holed lid member 52 is flush with the surface of the housing 41. Installed.

  Further, as shown in FIG. 6C, the end portion of the through hole 41a of the housing 41 is formed one step lower than the front end surface of the housing 41, and the side end portion 41i of the through hole 41a is formed as a plate-like plate. In order to hold the end portion 53a of the lid member 53, it may be formed so as to be inclined inward as it approaches the tip. The plate-like lid member 53 is also inserted into a recess 41n formed on the surface side of the holding through hole 41a of the housing 41 so that the surface of the plate-like lid member 53 is flush with the surface of the housing 41. Installed.

A cable holding member 44 may be provided. The cable holding member 44 of this example is formed with a slit or notch 44b serving as a notch for inserting the communication cable 12 from the side of the cable holding member 44 on one side surface. When the cut 44b is formed on the lower surface of the cable holding member 44 in this way, it is not necessary to pass the boot through the communication cable 12 before the housing 41 is fixed to the communication cable 12. Then, even after the housing 41 and the communication cable 12 are connected, the housing 41 and the cable holding member 44 can be connected, and the degree of freedom in the manufacturing procedure is increased, and the connector 40 that is easier to manufacture can be configured. .
