Description

Technical Field

[0001] The present disclosure relates to a joint terminal. Background Art

[0002] As the above-mentioned joint terminal, there is known a joint terminal described in JP2016-081625A. In the joint terminal described in JP2016-081625A, two electric wires are crimped and connected to each other.

[0003] The connector terminal described in JP2016-081625A is crimped to the connector terminal in a state where the front end faces of the two wires are facing each other. However, when it is desired to crimp the front end faces of the two wires in the same direction, when one wire is installed in a state where the other wire is installed, there is a problem that it is difficult to adjust the lead-out amount of the wire relative to the crimping piece.

[0004] The present disclosure has been made in view of the above-described circumstances, and an object of the present disclosure is to provide a joint terminal that prevents deviation in the lead-out amount of electric wires. Summary of the invention

[0005] The present disclosure provides a plate-shaped connector terminal that is arranged in an elongated shape. The connector terminal includes: a first mounting portion that is arranged on one side in the longitudinal direction and on which a first electric wire is mounted; a first crimping piece that is arranged on the first mounting portion and is configured to crimp the first electric wire; a second mounting portion that is arranged on the other side in the longitudinal direction and on which a second electric wire is mounted; a second crimping piece that is arranged on the second mounting portion and is configured to crimp the second electric wire; and an abutting portion that is formed by bending the end portion on the other side in the longitudinal direction toward the thickness direction of the second mounting portion so that the abutting portion abuts against the front end surface of the second electric wire.

[0006] The present disclosure has been briefly described above. The details of the present disclosure can be clarified by reading the modes for carrying out the present disclosure (hereinafter referred to as “embodiments”) described below with reference to the accompanying drawings.

[0012] Specific embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0013] In the following, for the convenience of description, Figures 1 to 5 As shown, "front", "rear", "left", "right", "up", and "down" are defined. The "front-rear direction", "left-right direction", and "up-down direction" are orthogonal to each other.

[0014] First embodiment

[0015] Figure 1 and Figure 2 A joint terminal 1 according to a first embodiment is shown. The joint terminal 1 according to the present embodiment is, for example, a terminal for connecting a covered electric wire 100 (= first electric wire) and a braided wire 200 (= second electric wire) arranged in a vehicle or the like. The covered electric wire 100 includes a core wire 101 and a covering portion 102 covering the core wire 101. The braided wire 200 includes a core wire 201, an inner insulator (not shown) covering the core wire 201, a braid (not shown) covering the inner insulator, and an outer insulator 202 covering the braid.

[0016] The joint terminal 1 is provided by punching and stamping a conductive metal plate. The joint terminal 1 includes two mounting portions 11 and 12, two crimping pieces 21 and 22, an abutment portion 3, an intermediate portion 4 and two bent portions 51 and 52, and is formed in an elongated shape in the up-down direction.

[0017] The mounting portion 11 (=first mounting portion) is disposed on the lower side (=one side in the longitudinal direction), and the coated electric wire 100 is mounted thereon. The mounting portion 11 is disposed perpendicularly to the front-rear direction. The crimping pieces 21 (=first crimping pieces) stand upright from both sides of the mounting portion 11 in the left-right direction and crimp the coated electric wire 100. In the present embodiment, the crimping pieces 21 are disposed at the lower end of the mounting portion 11. At one end of the coated electric wire 100, the coating 102 is removed to expose the core wire 101. The coated core wire 101 is mounted on the mounting portion 11 and crimped by the crimping pieces 21. The coated electric wire 100 is led out downward.

[0018] The mounting portion 12 (= second mounting portion) is disposed on the upper side (= the other side in the longitudinal direction), and the braided wire 200 is mounted thereon. The mounting portion 12 is disposed perpendicularly to the front-to-rear direction. The crimping pieces 22 (= second crimping pieces) stand upright rearward from both sides in the left-right direction of the mounting portion 12, and crimp the braided wire 200. In the present embodiment, the crimping piece 22 is disposed approximately at the center in the up-down direction of the mounting portion 12. At one end of the braided wire 200, the outer insulator 202, the braid (not shown), and the inner insulator (not shown) are removed to expose the core wire 201. The exposed core wire 201 is mounted on the mounting portion 12, and is crimped by the crimping piece 22.

[0019] The abutment portion 3 is formed by bending the upper end of the connector terminal 1 in an L-shape in the front-rear direction (=thickness direction of the mounting portion 12) and the front end surface of the core wire 201 of the braided wire 200 abuts the abutment portion 3 from below. The abutment portion 3 is formed perpendicular to the up-down direction.

[0020] The middle portion 4 is arranged between the mounting portion 11 and the mounting portion 12. The middle portion 4 is arranged perpendicular to the up-down direction. The bending portion 51 is arranged between the middle portion 4 and the mounting portion 11, and is formed by bending the rear end portion (the end portion on one side of the extension direction) of the middle portion 4 toward the lower side in the up-down direction (one side in the thickness direction of the middle portion 4). The bending portion 52 is arranged between the middle portion 4 and the mounting portion 12, and is formed by bending the front end portion (the end portion on the other side of the extension direction) of the middle portion 4 toward the upper side in the up-down direction (the other side in the thickness direction of the middle portion 4). The braided wire 200 is bent into an L shape along the middle portion 4 and is mounted on the mounting portion 12. That is, the braided wire 200 is led out rearward.

[0021] A process of connecting the covered electric wire 100 and the braided wire 200 using the joint terminal 1 will be described. First, the core wire 101 of the covered electric wire 100 exposed at the end is mounted on the mounting portion 11. At this time, the covered electric wire 100 is mounted in a state where the front end of the core wire 101 faces upward and the covered electric wire 100 is led out from the lower side. Thereafter, the front end of the crimping piece 21 approaches the core wire 101, and the core wire 101 of the covered electric wire 100 is crimped by the crimping piece 21. The core wire 201 exposed at the end of the braided wire 200 is mounted on the mounting portion 12. At this time, the front end face of the core wire 201 of the braided wire 200 abuts the abutment portion 3. The braided wire 200 is mounted in a state where the front end of the core wire 201 faces upward and the braided wire 200 is led out from the rear side along the middle portion 4. Thereafter, the front end of the crimping piece 22 approaches the core wire 201, and the core wire 201 of the braided wire 200 is crimped by the crimping piece 22.

[0022] According to the above embodiment, by providing the contact portion 3 on the joint terminal 1, the front end surface of the core wire 201 of the braided wire 200 can contact the contact portion 3. Therefore, the amount of the braided wire 200 drawn out from the crimping piece 22 can be prevented from varying.

[0023] like Figure 1 As shown, when the continuity check is performed on the braided wire 200, the continuity check probe 300 can be in contact with the abutment portion 3. Therefore, since the continuity check probe 300 does not directly contact the braided wire 200, it is possible to prevent the braid from being worn or disconnected.

[0024] According to the above embodiment, the connector terminal 1 is provided with the middle portion 4, and the braided wire 200 is bent into an L shape and mounted on the connector terminal 1. When the front end of the braided wire 200 is bent into an L shape, it is more difficult to adjust the lead-out amount, but the abutment portion 3 can prevent the deviation of the lead-out amount of the braided wire 200 from the crimping piece 22.

[0025] Second embodiment

[0026] Next, we will refer to Figure 3 and Figure 4 The second embodiment is described. In the accompanying drawings, the Figure 1 and Figure 2 The same parts as those of the joint terminal 1 shown in FIG. 1 are denoted by the same reference numerals, and a detailed description thereof is omitted.

[0027] As shown in the figure, the joint terminal 1B according to the second embodiment includes two mounting portions 11 and 12 , two crimping pieces 21 and 22 , an abutment portion 3B, an intermediate portion 4 , and two bent portions 51 and 52 , and is formed in an elongated shape in the up-down direction.

[0028] Since the mounting portions 11 and 12, the crimping pieces 21 and 22, the middle portion 4, and the bent portions 51 and 52 are the same as those in the above-mentioned first embodiment, their detailed description will be omitted here. The main difference between the first embodiment and the second embodiment is the shape of the abutment portion 3B. The abutment portion 3 according to the first embodiment is set to a flat plate shape. The abutment portion 3B according to the second embodiment is set to a curved shape close to the front end face of the braided wire 200 toward its central portion.

[0029] Therefore, if Figure 5 As shown, when the continuity check probe 300 contacts the abutment portion 3B for connection inspection, the continuity check probe 300 is guided to the center of the abutment portion 3B along the curved shape. The continuity check can be performed more accurately at the center portion closest to the braided wire 200.

[0030] The present disclosure is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. In addition, the materials, shapes, sizes, quantities, arrangement positions, etc. of the components in the above-described embodiments are arbitrarily selected and are not limited as long as the present disclosure can be implemented.

[0031] According to the first and second embodiments, the front end surface of the braided wire 200 abuts against the abutting portions 3 and 3B, but the present disclosure is not limited thereto, and the front end surface of the covered electric wire 100 may abut against the abutting portions 3 and 3B instead of the braided wire 200 .

[0032] According to the first and second embodiments described above, the bending portions 51 and 52 are provided on both sides of the middle portion 4, and the mounting portion 11 and the mounting portion 12 are separated in the front-rear direction, but the present disclosure is not limited thereto. The joint terminals 1 and 1B may be provided so that the mounting portion 11 and the mounting portion 12 are on the same plane without providing the bending portions 51 and 52 on both sides of the middle portion 4.

[0033] Here, the features of the above-mentioned embodiments of the joint terminal according to the present disclosure are briefly summarized and listed below (i) to (iv).

[0039] A second crimping piece (22) is disposed on the second mounting portion (12) and is configured to crimp the second electric wire (200); and

[0040] The abutment portion (3, 3B) is formed by bending the end portion on the other side (upper side) of the longitudinal direction (upper and lower directions) toward the thickness direction (front-to-back direction) of the second mounting portion (12) so that the abutment portion (3, 3B) abuts against the front end surface of the second electric wire (200).

[0041] According to the structure (i), by providing the abutment portion (3, 3B) on the connector terminal (1, 1B), the front end surface of the second electric wire (200) can abut the abutment portion (3, 3B), thereby preventing the deviation of the lead-out amount of the second electric wire (200) from the second crimping piece (22).

[0042] (ii)

[0043] In the joint terminal (1, 1B) according to (i),

[0044] The second electric wire (200) is formed of a braided wire.

[0045] According to the configuration (ii), when conducting a continuity check on the braided wire (200), the continuity check probe (300) can contact the abutment portion (3, 3B). Therefore, since the continuity check probe (300) does not directly contact the braided wire (200), the braid can be prevented from being worn or disconnected.
