[0010] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0011] For convenience of explanation, "front", "rear", "left", "right", "upper", and "lower" are defined below as shown in Figures 1 to 5. The "front-rear direction", "left-right direction", and "up-down direction" are perpendicular to each other.

[0012] (First embodiment) A joint terminal 1 of a first embodiment is shown in Figures 1 and 2. The joint terminal 1 of this embodiment is a terminal for connecting a covered electric wire 100 (= first electric wire) and a braided wire 200 (= second electric wire) arranged in, for example, a vehicle. The covered electric wire 100 is composed of a core wire 101 and a covering portion 102 that covers the core wire 101. The braided wire 200 is composed of a core wire 201, an inner insulator (not shown) that covers the core wire 201, a braid (not shown) that covers the inner insulator, and an outer insulator 202 that covers the braid.

[0013] The joint terminal 1 is formed by punching and pressing a conductive metal plate. The joint terminal 1 has two mounting portions 11, 12, two crimping pieces 21, 22, a butting portion 3, a middle portion 4, and two bent portions 51, 52, and is provided long in the vertical direction.

[0014] The mounting part 11 (=first mounting part) is provided on the lower side (=one side in the longitudinal direction) and the covered electric wire 100 is mounted thereon. The mounting part 11 is arranged vertically in the front-rear direction. The crimping pieces 21 (=first crimping pieces) are provided standing from both the left and right sides of the mounting part 11 toward the rear side and crimp the covered electric wire 100. In this embodiment, the crimping pieces 21 are provided at the lower end of the mounting part 11. At the end of the covered electric wire 100, the covering part 102 is removed to expose the core wire 101. This covered core wire 101 is mounted on the mounting part 11 and crimped by the crimping pieces 21. The covered electric wire 100 is drawn out to the lower side.

[0015] The mounting portion 12 (=second mounting portion) is provided on the upper side (=other side in the longitudinal direction), and the braided wire 200 is mounted thereon. The mounting portion 12 is disposed vertically in the front-rear direction. The crimping pieces 22 (=second crimping pieces) are provided standing from both the left and right sides of the mounting portion 12 toward the rear side, and crimp the braided wire 200. In this embodiment, the crimping pieces 22 are provided at approximately the center in the up-down direction of the mounting portion 12. The terminal of the braided wire 200 has the external insulator 202, the braid (not shown), and the internal insulator (not shown) removed to expose the core wire 201. This exposed core wire 201 is mounted on the mounting portion 12, and is crimped by the crimping pieces 22.

[0016] The butt portion 3 is provided by bending the upper end portion of the joint terminal 1 rearward in the front-rear direction (= thickness direction of the mounting portion 12) into an L-shape, and is butted against the tip surface of the core wire 201 of the braided wire 200 from below. The butt portion 3 is disposed vertically in the up-down direction.

[0017] The intermediate portion 4 is provided between the mounting portion 11 and the mounting portion 12. The intermediate portion 4 is disposed vertically in the up-down direction. The bent portion 51 is provided between the intermediate portion 4 and the mounting portion 11, and is provided by bending the lower end portion (end portion on one side in the longitudinal direction) of the mounting portion 11 toward the lower side in the up-down direction (one side in the thickness direction of the intermediate portion 4). The bent portion 52 is provided between the intermediate portion 4 and the mounting portion 12, and is provided by bending the upper end portion (end portion on the other side in the longitudinal direction) of the mounting portion 12 toward the upper side in the up-down direction (the other side in the thickness direction of the intermediate portion 4). The braided wire 200 is bent in an L-shape along the intermediate portion 4 and mounted on the mounting portion 12. That is, the braided wire 200 is drawn out to the rear side.

[0018] A procedure for connecting the covered electric wire 100 and the braided wire 200 using the joint terminal 1 described above will be described. First, the core wire 101 exposed at the end of the covered electric wire 100 is mounted on the mounting portion 11. At this time, the core wire 101 is mounted with its tip surface facing upward and the covered electric wire 100 pulled out from the bottom. Thereafter, the tip of the crimping piece 21 is brought close to the core wire 101, and the core wire 101 of the covered electric wire 100 is crimped by the crimping piece 21. In addition, the core wire 201 exposed at the end of the braided wire 200 is mounted on the mounting portion 12. At this time, the tip surface of the core wire 201 of the braided wire 200 is abutted against the abutting portion 3. In addition, the core wire 201 is mounted with its tip surface facing upward and the braided wire 200 pulled out from the rear side along the middle portion 4. Thereafter, the tip of the crimping piece 22 is brought close to the core wire 201 , and the crimping piece 22 crimps the core wire 201 of the braided wire 200 .

[0019] According to the above-described embodiment, by providing the butt portion 3 in the joint terminal 1, the tip end face of the core wire 201 of the braided wire 200 can be butted against the butt portion 3. This makes it possible to suppress variation in the protruding margin of the braided wire 200 from the crimping piece 22.

[0020] 1, a continuity test of the braided wire 200 can be performed by applying a voltage detection probe 300 to the butting portion 3. Therefore, the voltage detection probe 300 does not directly contact the braided wire 200, which prevents the braid from fraying or breaking.

[0021] According to the above-described embodiment, the joint terminal 1 is provided with the intermediate portion 4, and the braided wire 200 is bent into an L shape and mounted on the joint terminal 1. When the tip of the braided wire 200 is bent into an L shape, it becomes even more difficult to adjust the protruding portion, but the abutting portion 3 can suppress variations in the protruding portion of the braided wire 200 from the crimping piece 22.

[0022] Second embodiment Next, a second embodiment will be described with reference to Figures 3 and 4. In these figures, parts equivalent to those of the joint terminal 1 shown in Figures 1 and 2 already described in the first embodiment above are designated by the same reference numerals, and detailed description thereof will be omitted.

[0023] As shown in the same figure, the joint terminal 1B of the second embodiment has two mounting portions 11, 12, two crimping pieces 21, 22, a butting portion 3B, an intermediate portion 4, and two bent portions 51, 52, and is elongated in the vertical direction.

[0024] The mounting portions 11, 12, the crimping pieces 21, 22, the intermediate portion 4, and the bent portions 51, 52 are the same as those in the first embodiment described above, and therefore detailed description thereof will be omitted here. The major difference between the first embodiment and the second embodiment is the shape of the butting portion 3B. The butting portion 3 in the first embodiment is provided in a flat plate shape. The butting portion 3B in the second embodiment is provided in a curved shape that approaches the tip surface of the braided wire 200 as it approaches the center portion.

[0025] 5, when the voltage detection probe 300 is brought into contact with the butting portion 3B to perform a continuity test, the voltage detection probe 300 is guided along the curved shape to the center of the butting portion 3B. Since the center is the location closest to the braided wire 200, a more accurate continuity test can be performed.

[0026] The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.

[0028] According to the first and second embodiments described above, the bent portions 51, 52 are provided on both sides of the intermediate portion 4, and the mounting portion 11 and the mounting portion 12 are spaced apart in the front-rear direction, but this is not limited to this. The joint terminals 1, 1B may be provided so that the mounting portion 11 and the mounting portion 12 are on the same plane without providing the bent portions 51, 52 on both sides of the intermediate portion 4.
