  2. Description of the Related Art Conventionally, there has been known a connector having a configuration in which terminal portions are provided at both ends of a conductive member made of a plurality of metal strands and the conductive member is accommodated in a housing. For example, in Patent Document 1, a shield having a configuration in which a terminal fitting connected to a mating terminal is connected to a terminal of a braided wire as a conductive member formed by braiding a plurality of electric wires, and the braided wire is accommodated in a housing. A connector is disclosed.

JP 2007-26759 A

  By the way, in the connector as described above, when each member thermally expands due to heat generation due to a thermal environment or energization, a so-called minute connection between the conductive member and the counterpart terminal is caused by a reaction force received by the conductive member from the housing. There is a risk of sliding wear. Therefore, a part of the conductive member bulges outward in the width direction to improve the flexibility of the conductive member, thereby reducing the reaction force that the conductive member receives from the housing and preventing such fine sliding wear. The structure to do is known.

  Here, in FIG. 10, a conventional connector 201 having a configuration in which a bulging portion 214 bulging outward in the width direction is formed in a part of the braided wire 210 and the braided wire 210 is accommodated in the housing 220. A schematic sectional view is shown. In the connector 201, as shown in FIG. 10, a first terminal fitting 231 and a second terminal fitting 232 are fixed to both ends of the braided wire 210, respectively. The first terminal fitting 231 is accommodated in the first accommodating portion 221 of the housing 220, and the bulging portion 214 and the second terminal fitting 232 are accommodated in the second accommodating portion 222 of the housing 220.

  However, in the connector 201 shown in FIG. 10, since the bulging portion 214 is formed, a part of the braided wire 210 is connected to the opening edge 221 </ b> A located on the second housing portion 222 side in the first housing portion 221 of the housing 220. It is close. For this reason, in the extending direction of the braided wire 210, a part of the braided wire 210 may interfere with the opening edge 221A. In this way, when a part of the braided wire 210 interferes with a part of the housing 220 in the extending direction of the braided wire 210, the reaction force received by the braided wire 210 from the housing 220 fluctuates or increases, and the fine sliding wear is sufficiently performed. Cannot be prevented.

  The present invention has been created in view of the above-described problems, and an object thereof is to stabilize a reaction force that a conductive member receives from a housing.

  The connector of the present invention comprises a plurality of metal wires, has flexibility, and is provided with a first terminal portion provided at one end portion in the extending direction and at the other end portion in the extending direction. A conductive member having a second terminal portion and a bulging portion that bulges outward in the width direction, and has a cylindrical shape and the first terminal in a posture in which the cylindrical axis direction and the extending direction coincide with each other. A housing having a first housing portion that houses the first housing portion and a second housing portion that is continuous from the first housing portion and houses the bulging portion and the second terminal portion. In the above, a gap is provided between an opening edge located on the second housing portion side of the first housing portion and the bulging portion.

  According to the connector, a gap is provided between the housing and the bulging portion of the conductive member in the extending direction of the conductive member, so that a part of the conductive member interferes with the housing in the extending direction. Can be prevented or suppressed. For this reason, it is possible to prevent or suppress the reaction force that the conductive member receives from the housing from fluctuating or increasing due to a part of the conductive member interfering with the opening edge of the housing in the extending direction of the conductive member. . Thus, in the connector described above, the reaction force that the conductive member receives from the housing can be stabilized.

  In the above connector, a gap may be provided between the opening edge and the conductive member in the width direction.

  According to this configuration, since the conductive member is less likely to interfere with the opening edge of the housing, the reaction force that the conductive member receives from the housing can be further stabilized.

  Another aspect of the present invention is a method for manufacturing the above connector, wherein the terminal part forming step of forming the first terminal part and the second terminal part at both ends of the conductive member, and the terminal part After the forming step, an insertion step of inserting the first terminal portion of the conductive member into a cylindrical jig whose one end portion is closed until the tip portion of the conductive member comes into contact with the deepest portion of the jig; After the inserting step, the conductive member is pushed to the jig side and contracted to locally buckle a part of the conductive member to form the bulging portion, and the bulging portion And a housing step of taking out the conductive member from the jig and housing the first terminal portion in the first housing portion of the housing after the projecting portion forming step, the insertion step and the bulging portion formation In the step, the opening diameter is the opening diameter of the first accommodating portion. Together are lower, the dimensions of the tube axis direction is characterized by using the jig which is equal to or greater than the dimensions of the tube axis direction of the first housing portion.

  According to the connector manufacturing method described above, in the bulging portion forming step, the bulging portion can be formed in a part of the portion of the conductive member that protrudes from the jig by pressing the conductive member toward the jig and contracting. it can. At this time, in the extending direction of the braided wire, the braided wire is buckled and deformed in a direction in which the bulging portion is separated from the opening edge of the jig. For this reason, since the dimension in the cylinder axis direction of the jig is not less than the dimension in the cylinder axis direction of the first housing part, the first terminal part is housed in the first housing part after the bulging part forming step. Thus, a gap can be formed between the opening edge located on the second housing portion side of the first housing portion and the bulging portion in the cylinder axis direction of the first housing portion, that is, in the extending direction of the conductive member. .

  Moreover, the constricted part dented inside can be formed in a part of site | part accommodated in the jig | tool among the electrically-conductive members by pushing and contracting a conductive member to the jig | tool side in a bulging part formation process. At this time, in the width direction of the conductive member, the conductive member is deformed in a direction in which the portion that becomes the constricted portion of the conductive member is separated from the opening edge of the jig. For this reason, since the opening diameter of the jig is equal to or smaller than the opening diameter of the first housing portion, the width of the conductive member can be obtained by housing the first terminal portion in the first housing portion after the bulging portion forming step. In the direction, a gap can be formed between the opening edge located on the second housing portion side of the first housing portion and the conductive member. As a result, in the connector manufacturing method described above, in the extending direction of the conductive member, a part of the conductive member can be prevented or suppressed from interfering with the housing, and the reaction force that the conductive member receives from the housing can be stabilized. A connector that can be made can be manufactured.

  Another aspect of the present invention is a method for manufacturing the above connector, wherein the terminal part forming step of forming the first terminal part and the second terminal part at both ends of the conductive member, and the terminal part After the forming step, an insertion step of inserting the first terminal portion of the conductive member into a cylindrical jig whose one end portion is closed until the tip portion of the conductive member comes into contact with the deepest portion of the jig; After the inserting step, a portion of the conductive member protruding from the jig is bent several times in a plurality of directions to locally buckle a part of the conductive member, thereby forming a bulging portion. A projecting portion forming step, and after the bulging portion forming step, the step of taking out the conductive member from the jig and accommodating the first terminal portion in the first accommodating portion of the housing, In the insertion step and the bulging portion forming step, the opening There together are less opening diameter of the first housing portion, the dimensions of the tube axis direction is characterized by using the jig which is equal to or greater than the dimensions of the tube axis direction of the first housing portion.

  Also according to the connector manufacturing method, the bulging portion and the constricted portion can be formed in a part of the conductive member in the bulging portion forming step. Further, a gap can be formed between the opening edge located on the second housing portion side of the first housing portion and the bulging portion in the extending direction of the conductive member, and the first housing in the width direction of the conductive member. A gap can be formed between the opening edge located on the second accommodating portion side of the portion and the conductive member. As a result, it is possible to prevent or suppress a part of the conductive member from interfering with the housing in the extending direction of the conductive member, and to manufacture a connector capable of stabilizing the reaction force that the conductive member receives from the housing. be able to.

  According to the present invention, the reaction force that the conductive member receives from the housing can be stabilized.

Further, a constricted portion 16 that is constricted in an arc shape inward in the width direction is provided at the starting point of the braided wire 10 on the lower side (first terminal fitting 31 side) of the bulging portion 14.

  The housing 20 is a member that accommodates the braided wire 10, and has a first accommodation portion 21, a second accommodation portion 22, and a lid portion 23 as shown in FIG. 1. The braided wire 10 is accommodated in the housing 20 with the extending direction of the braided wire 10 along the vertical direction, with the first terminal fitting 31 side as the lower side.

  The 1st accommodating part 21 has comprised the cylinder shape, and is located in the lower side of the housing 20 with the attitude | position in which the cylinder axial direction corresponds with an up-down direction. The opening diameter of the first accommodating portion 21 is slightly larger than the width direction dimension of the braided wire 10. In the 1st accommodating part 21, the braided wire near the 1st terminal metal fitting 31 and the 1st terminal metal fitting 31 fixed to the braided wire 10 with the attitude | position in which the cylinder axis direction and the extending direction of the braided wire 10 correspond.

The tip of the first terminal fitting 31 is located at the same height as the lower opening edge 21 </ b> B of the first accommodating part 21. In the connector 1, the lower opening edge 21 </ b> B of the first housing portion 21 serves as a connection port with the counterpart terminal. Note that an overhanging portion 21 </ b> C is provided on the outer peripheral surface of the first accommodating portion 21 so as to project outward in a bowl shape.

  The 2nd accommodating part 22 is taken as the cylindrical member larger than the 1st accommodating part 21, The cylinder axis direction corresponds with the up-down direction. The second accommodating portion 22 supports the first accommodating portion 21 in a floating manner by having the lower opening edge 22 </ b> B attached to the overhanging portion 21 </ b> C of the first accommodating portion 21. Thereby, the opening edge 22B of the lower side of the 2nd accommodating part 2 is closed by the 1st accommodating part 21, and it is in the state which the 1st accommodating part 21 and the 2nd accommodating part 22 continued.

  Within the second housing portion 22, a portion of the braided wire 10 that protrudes from the first housing portion 21, that is, the bulging portion 14 and the second terminal fitting 32 fixed to the braided wire 10 are provided in the second housing portion. It is accommodated in a form away from the inner wall of 22 (in a form that does not interfere with the second accommodation part 22). The distal end portion of the second terminal fitting 32 is fastened and connected by a bolt B to a terminal (not shown) on the electric wire side that is routed on a terminal block 24 disposed in the housing 20.

  The lid portion 23 is a lid-like member, and is attached to the upper opening edge 22B of the second accommodating portion 22 so as not to interfere with the braided wire 10. Thereby, the opening edge 22 </ b> A on the upper side of the second accommodating portion 22 is closed by the lid portion 23.

  In the connector 1 of the present embodiment configured as described above, as shown in FIG. 1, the first housing portion in the extending direction of the braided wire 10 (vertical direction, the cylinder axis direction of the first housing portion 21). A gap S <b> 1 is provided between the opening edge 21 </ b> A (opening edge located on the second housing portion 22 side) 21 </ b> A and the bulging portion 14. Further, in the width direction of the braided wire 10, a gap S <b> 2 is provided between the opening edge 21 </ b> A on the upper side of the first housing portion 21 and the braided wire 10.

  Then, the manufacturing method of the connector 1 in this embodiment is demonstrated. In this method, the bulging portion 14 is formed on the braided wire 10 using the jig 40. As shown in FIG. 2, the jig 40 has a cylindrical shape with one end closed, and the opening diameter thereof is slightly smaller than the opening diameter of the first accommodating portion 21 of the housing 20. The dimension in the cylinder axis direction is slightly longer than the dimension in the cylinder axis direction of the first housing portion 21 of the housing 20.

  In this method, first, as shown in FIG. 2, the first terminal fitting 31 and the second terminal fitting 32 are fixed to both ends of the tubular braided wire 10 by resistance welding (an example of a terminal portion forming step). . As a result, the braided wire 10 has a wide solid shape.

  Next, the jig 40 is prepared and the opening side thereof is directed upward (see FIG. 2). As shown in FIG. 3, the cylindrical axis direction of the jig 40 and the extending direction of the braided wire 10 coincide with each other. In the posture, the first terminal fitting 31 and the braided wire 10 in the vicinity thereof are inserted into the jig 40 until the tip of the first terminal fitting 31 comes into contact with the deepest portion 41 of the jig 40 (in the insertion step). One case). Thereby, the first terminal fitting 31 and the portion of the braided wire 10 in the vicinity thereof are accommodated in the jig 40.

  Next, the braided wire 10 is further pushed into the jig 40 and the braided wire 10 is pressed and contracted (an example of a bulging portion forming step). Then, the part of the braided wire 10 located at the same height as the opening edge 40A of the jig 40 in the vertical direction interferes with the opening edge 40A of the jig 40. And since the metal strand 12 which overlaps with the 2nd terminal metal fitting 32 is solidified, it is under the 2nd terminal metal fitting 32 among the site | parts which protruded from the jig | tool 40 of the braided wire 10 by compressing the braided wire 10. The site | part located in the side is locally buckled and bulged to the outer side of the width direction, and the bulging part 14 is formed (refer FIG.4 and FIG.5). At this time, the braided wire 10 is buckled and deformed in a direction in which the bulging portion 14 is separated from the opening edge 40A of the jig 40 in the vertical direction (extending direction of the braided wire 10).

  Here, in this embodiment, since the dimension in the cylinder axis direction of the jig 40 used in the manufacturing process is slightly longer than the dimension in the cylinder axis direction of the first accommodating portion 21, the first terminal fitting The portion of the braided wire 10 having the same height as the opening edge 40A of the jig 40 in a state where the 31 is accommodated in the jig 40 is the first accommodation in the state where the first terminal fitting 31 is accommodated in the first accommodation portion 21. Compared to the portion of the braided wire 10 that is the same height as the opening edge 21A on the upper side of the portion 21, it is positioned on the upper side. For this reason, the first terminal fitting 31 is accommodated in the first accommodating portion 21 after the bulging portion 14 is formed, so that the lower side of the bulging portion 14 in the vertical direction, that is, the extending direction of the braided wire 10. Is formed at a position sufficiently away from the upper opening edge 21A of the first housing portion 21, and a sufficient gap S1 is formed between the opening edge 21A and the bulging portion 14.

  On the other hand, in the portion of the braided wire 10 that is accommodated in the jig 40, the braided wire 10 is further pushed into the jig 40 in the bulging portion forming step, whereby the portion of the braided wire 10 in the vicinity of the first terminal fitting 31 is obtained. A force that bulges outward in the width direction is applied to the portion, and the portion bulges until the width becomes equal to the opening diameter of the jig 40. Thus, in addition to the bulging portion 14, the portion of the braided wire 10 in the vicinity of the first terminal fitting 31 is bulged, so that the portion between them, that is, the height substantially equal to the opening edge 40 </ b> A of the jig 40 in the vertical direction. A portion of the braided wire 10 located in the region is deformed in a direction away from the opening edge 40A in the width direction of the braided wire 10, and is slightly recessed inward, so that the constricted portion 16 is formed in the portion.

  Here, in this embodiment, since the opening diameter of the jig 40 used in the manufacturing process is slightly smaller than the opening diameter of the first housing portion 21, the first terminal fitting 31 is housed in the first housing portion 21. The distance between the opening edge 21A on the upper side of the first housing portion 21 and the constricted portion 16 in the state is such that the opening edge 40A of the jig 40 and the constricted portion 16 in the state where the first terminal fitting 31 is accommodated in the jig 40. It will be larger than the distance between. For this reason, by accommodating the 1st terminal metal fitting 31 in the 1st accommodating part 21 after the narrowed part 16 is formed, the narrowed part 16 is the opening edge of the upper side of the 1st accommodating part 21 in the width direction of the braided wire 10. It is formed at a position sufficiently away from 21A, and a sufficient gap S2 is formed between the opening edge 40A and the constricted portion 16.

  Next, the 1st accommodating part 21 is attached to the 2nd accommodating part 22, the braided wire 10 is taken out from the jig | tool 40, the cylinder axis direction of the 1st accommodating part 21 and the braided wire 10 are attached to the 1st accommodating part 21 of the housing 20. The first terminal fitting 31 and the portion of the braided wire 10 in the vicinity of the first terminal fitting 31 until the leading end of the first terminal fitting 31 reaches the lower opening edge 21B of the first accommodating portion 21 in a posture that matches the extending direction of Accommodating (an example of an accommodating process). Thereafter, the lid portion 23 is attached to the second accommodating portion 22. Thereby, the bulging part 14 and the 2nd terminal metal fitting 32 are accommodated in the 2nd accommodating part 22, and the connector 1 shown in FIG. 1 is completed.

  As described above, according to the connector 1 of the present embodiment, the gap S <b> 1 is formed between the housing 20 and the bulging portion 14 of the braided wire 10 in the extending direction of the braided wire 10. It is possible to prevent or suppress a part of the braided wire 10 from interfering with the housing 20 in the extending direction of 10. For this reason, the reaction force that the braided wire 10 receives from the housing 20 due to a part of the braided wire 10 interfering with the upper opening edge 21 </ b> A in the first accommodating portion 21 of the housing 20 in the extending direction of the braided wire 10. Can be prevented or suppressed from changing or increasing. Thus, in the connector 1 of this embodiment, the reaction force which the braided wire 10 receives from the housing 20 can be stabilized.

  In the connector of the present embodiment, a gap S <b> 2 is formed between the upper opening edge 21 </ b> A and the braided wire 10 in the first accommodating portion 21 of the housing 20 in the width direction of the braided wire 10. With such a configuration, a part of the braided wire 10 is less likely to interfere with the housing 20, so that the reaction force that the braided wire 10 receives from the housing 20 can be further stabilized.

  In the connector 1 of the present embodiment, as described above, the dimension in the cylinder axis direction of the jig 40 used in the manufacturing process is slightly longer than the dimension in the cylinder axis direction of the first housing portion 21. Thus, the gap S1 formed between the opening edge 21A on the upper side of the first housing portion 21 and the bulging portion 16 can be sufficiently separated in the vertical direction. Furthermore, in the connector 1 of the present embodiment, as described above, the opening diameter of the jig 40 is slightly smaller than the opening diameter of the first housing portion 21, so that in the width direction of the braided wire 10. The gap S <b> 2 formed between the opening edge 21 </ b> A on the upper side of the first housing portion 21 and the constricted portion 16 can be sufficiently separated.

Next, Embodiment 2 will be described with reference to FIGS. As shown in FIG. 7, the connector 101 of the present embodiment is slightly smaller in size of the bulging portion 114 than that of the first embodiment, but the configuration thereof is the same as that of the first embodiment. . The jig 140 used in the manufacturing process has the same configuration as that of the first embodiment. 7, 8, and 9, the parts obtained by adding the numeral 100 to the reference numerals in FIGS. 1, 3, and 6 are the same as the parts described in the first embodiment.

  The connector 101 of this embodiment is different from that of the first embodiment only in the manufacturing method. Specifically, only the step of forming the bulging portion 114 is different from the manufacturing method of the first embodiment. Since the configuration of the connector 101 is the same as that of the first embodiment as described above, the description of the structure, operation, and effect is omitted. Further, in the manufacturing method of the connector 101, the steps other than the step of forming the bulging portion 114 are the same as those in the first embodiment, and thus the description thereof is omitted.

  In the manufacturing method of the connector 101 of the present embodiment, the first terminal fitting 131 and the portion of the braided wire 110 in the vicinity of the first terminal fitting 131 are located inside the jig 140, and the tip portion of the first terminal fitting 131 is connected to the deepest portion 141 of the jig 140. After insertion until contact (see FIG. 8), the portion of the braided wire 110 that protrudes from the jig is pushed and bent a plurality of times in a plurality of directions (an example of a bulging portion forming step). At this time, the part accommodated in the jig 140 of the braided wire 110 is regulated by the jig 140 on both sides in the width direction, and the metal wire 112 overlapping the second terminal fitting 132 is solidified. Of the protruding portion, the portion located below the second terminal fitting 132 is locally buckled and bulged outward in the width direction to form a bulging portion 114 (see FIG. 9). At this time, like the manufacturing method shown in the first embodiment, the braided wire 110 is buckled in the direction in which the bulging portion 114 is separated from the opening edge 140A of the jig 140 in the vertical direction (the extending direction of the braided wire 10). And deform.

  On the other hand, the protruding part is pushed and bent a plurality of times, so that the part of the braided wire 110 positioned substantially at the same height as the opening edge 140A of the jig 140 in the vertical direction becomes the jig 140 in the width direction of the braided line 110. It is pressed inward by interfering with the opening edge 140A, and the portion is slightly recessed inward, and a constricted portion 116 is formed in the portion.

  Thereafter, the braided wire 110 is taken out from the jig 140, the first terminal fitting 131 of the braided wire 110 and the portion of the braided wire 110 in the vicinity thereof are accommodated in the first accommodating portion 121 of the housing 120, and the lid portion 123 of the housing 120 is removed. It attaches to the 2nd accommodating part 122. FIG. Thereby, the bulging portion 114 and the second terminal fitting 132 are accommodated in the second accommodating portion 122, and the connector 101 shown in FIG. 7 is completed.

  In the present embodiment, even in such a manufacturing method, the dimension in the cylinder axis direction of the jig 140 is equal to or larger than the dimension in the cylinder axis direction of the first accommodating portion 121, and thus the first embodiment has been described. Similar to the manufacturing method, the bulging portion 114 can be formed such that a gap S <b> 1 is formed between the upper opening edge 121 </ b> A of the first housing portion 121 and the bulging portion 114. As a result, it is possible to prevent or suppress the reaction force received by the braided wire 110 from the housing 120 from fluctuating or increasing due to the braided wire 110 interfering with the upper opening edge 121A of the first accommodating portion 121 of the housing 120. be able to.
