<First embodiment>
A connector according to a first embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the entire connector 10A according to the first embodiment. As shown in FIG. 1, the connector 10A has, for example, a cylindrical connector body 11, and a slit 12 is provided over the entire length from one end 111 side to the other end 112 side in the longitudinal direction. Therefore, the connector 10A has a C-shaped cross section. The connector 10A can be integrally formed by casting using a copper material that is conductive and can be easily crimped.

A wall portion 13A is provided inside the connector main body 11 to partition the internal space. A pair of wall portions 13A are provided, and are provided in parallel along the slit 12 over the entire length of the connector main body 11 in the longitudinal direction. The wall portion 13A can be formed integrally with the connector main body 11 using a copper material.

The wall portion 13A has base ends 131 at both ends (edges) 121 in the width direction of the slit 12, and tip ends 132 are provided in the internal space. A bending line 133 is provided along the longitudinal direction between the proximal end portion 131 and the distal end portion 132 . The distal end side of the bending line 133 is bent toward the inner surface 113 of the connector main body 11 .

Next, branch connection between the trunk cable 1 and the branch cable 2 using the connector 10A described above will be described. FIG. 2 is a perspective view showing a state in which the trunk cable 1 and a plurality of branch cables 2 are branched and connected using the connector 10A according to the first embodiment. Also, FIG. 3(a) is a cross-sectional view showing a state before the trunk cable 1 and the branch cable 2 are inserted into the connector 10A and crimped, and FIG. 3(b) shows a state after crimping. It is a sectional view.

As shown in FIG. 2, the covering 1a of the trunk cable 1, which is not at the end, is removed by a length corresponding to the length of the connector 10A to expose the trunk conductor 1b. At the same time, the cover 2a of the end of the branch cable 2 to be connected is removed by a predetermined length to expose the branch conductor 2b. Then, as shown in FIG. 3A, the branch line conductor 2b is inserted between the wall portion 13A and the connector main body 11 from the one end 111 side or the other end 112 side of the connector 10A. Then, the trunk conductor 1b is inserted through the slit 12. As shown in FIG.

Next, as shown in FIG. 3B, the connector 10A is crimped in the direction of the arrow so as to close the slit 12. Then, as shown in FIG. As a result, the distal end portion 132 of the wall portion 13A abuts against the trunk conductor 1b and the inner surface 113 of the connector main body 11, so that the bending line 133 is further bent to reliably separate the branch conductor 2b and the trunk conductor 1b.

As described above, according to the connector 10A according to the present embodiment, the cylindrical connector main body 11 is provided with the slit 12 continuous from the one end 111 side to the other end 112 side. A wall portion 13</b>A is provided on the inner surface 113 of the connector main body 11 to divide the internal space of the connector main body 11 continuously from the one end 111 side to the other end 112 side. When branching and connecting the trunk conductor 1b and the branch conductor 2b, the trunk conductor 1b is inserted into the central portion of the internal space that is partitioned by the wall portion 13A and continues to the slit 12, and the wall portion 13A and the inner surface 113 of the connector main body 11 are connected. The connector 10A is crimped by inserting the branch line conductor 2b into the section of . Therefore, conductors of a plurality of electric wires can be crimped collectively. Also, even if the diameter of the connector 10A is reduced, since the main conductor 1b and the branch conductor 2b are not in direct contact with each other, a part of the thin branch conductor 2b is pushed by the main conductor 1b and pushed out from the slit 12 to the outside of the connector 10A. It can reduce the possibility of dropping out.

Furthermore, according to the connector 10A of this embodiment, the base end 131 of the wall 13A is connected to the end 121 of the slit 12 . Therefore, the branch line conductor 2b is blocked from the slit 12 by the base end portion 131 of the wall portion 13A, so that part of the branch line conductor 2b can be more reliably prevented from falling out of the slit 12 to the outside.

Furthermore, according to the connector 10A of this embodiment, the wall portion 13A is provided with the bending line 133 parallel to the continuous direction. Therefore, by bending the distal end portion 132 of the wall portion 13A toward the inner surface 113 of the connector main body 11, when the plurality of branch line conductors 2b are inserted into the wall portion 13A and crimped, the branch line conductors 2b are displaced. Therefore, it is possible to more reliably prevent part of the branch line conductor 2b from falling out of the slit 12 to the outside.

A closed space is formed by the wall portion 13B. A bending line 133 is provided in the central portion of the wall portion 13B.

When connecting the trunk cable 1 and the branch cable 2, as shown in FIG. 5(a), the branch conductor 2b is inserted into the space closed by the wall portion 13B. Then, as shown in FIG. 5B, when the connector 10B is crimped in the direction of the arrow, the wall portion 13B is bent at the bending line 133. As shown in FIG.

As described above, according to the connector 10B according to the present embodiment, the wall portion 13B is connected to the inner surface 113 of the connector main body 11 at the tip portion 132 opposite to the base end portion 131. The inserted branch line conductor 2b is sealed by the wall portion 13B. Therefore, it is possible to reliably prevent part of the branch line conductor 2b from falling out of the slit 12 to the outside. Further, since the wall portion 13B is provided with the bending line 133 in the central portion, the deformation direction of the wall portion 13B can be restricted when crimped.
