DETAILED DESCRIPTION

[0018] Reference Figure 1Some existing terminal connectors have two rows of terminals 500, each of which has an upper step 510 and a lower step 520. The upper step 510 and the lower step 520 each have two mutually perpendicular step surfaces 530. A foam 540 is provided between the two rows of terminals 500, and the foam 540 is elastic. However, the terminals 500 are relatively long and have a large deflection, resulting in an unstable position of the two rows of terminals 500 and an unstable distance between the two rows of terminals 500. When assembling and plugging the terminals 500 into the connector 600, due to the unstable position and unstable spacing of the two rows of terminals 500 and the relatively long insertion holes of the connector 600, the terminals 500 are difficult to insert into the connector 600, and may even be unable to fully insert into the bottom of the connector 600, making assembly more difficult. To this end, an embodiment of the present invention provides a jig for inserting terminals into the connector, which can reduce the difficulty of inserting the terminals 500 into the connector 600 and ensure that the terminals 500 can be fully inserted into the bottom of the connector 600.

[0019] The embodiments of the present invention are described in detail below.

[0020] Reference Figures 2 to 9 , an embodiment of the present invention provides a fixture for inserting a terminal into a connector, including a machine 100, a first positioning assembly, a second positioning assembly and a pressing assembly, the first positioning assembly is provided on the machine 100, and includes a first positioning member 210 and a second positioning member 220, the first positioning member 210 is used to position the terminal 500, and the second positioning member 220 is used to position the connector 600, the first positioning member 210 and the second positioning member 220 can move toward each other so that the terminal 500 is inserted into the bottom of the connector 600; the second positioning member The positioning component is provided on the machine 100, including a third positioning member 310 and a fourth positioning member 320, and the third positioning member 310 and the fourth positioning member 320 are respectively used to position the upper step 510 and the lower step 520 of the terminal 500; the clamping component is provided on the machine 100, including a first clamping member 410 and a second clamping member 420, and the first clamping member 410 and the second clamping member 420 are respectively used to clamp the upper buckle 610 and the lower buckle of the connector 600 (not shown in the drawings, the structure of the lower buckle can refer to the upper buckle 610).

[0021] Reference Figure 4 During assembly, the terminal 500 can be pre-installed on the connector 600, and the first positioning member 210 is used to position the terminal 500, and the second positioning member 220 is used to position the connector 600, and the terminal 500 and the connector 600 are preliminarily positioned. Figure 5 and Figure 6, use the third positioning member 310 and the fourth positioning member 320 to position the upper step 510 and the lower step 520 of the terminal 500 respectively, and perform secondary positioning on the terminal 500 to fix the distance between the two rows of terminals 500, ensure the accuracy of the position between the two rows of terminals 500 and the connector 600, and reduce the difficulty of inserting the terminal 500 into the connector 600 later. Afterwards, move the first positioning member 210 and the second positioning member 220 towards each other, either the first positioning member 210 moves towards the second positioning member 220 or the second positioning member 220 moves towards the first positioning member 210, so that the terminal 500 can be accurately, stably and smoothly plugged into the bottom of the connector 600. Finally, refer to Figure 7 The first pressing member 410 and the second pressing member 420 are used to respectively press the upper buckle 610 and the lower buckle of the connector 600, thereby achieving automatic plugging of the terminal 500 and the connector 600. Specifically, the first pressing member 410 and the second pressing member 420 are respectively the upper pressing block and the lower pressing block, which can be driven by a driving member such as a motor or a cylinder to move vertically, thereby pressing the buckle of the connector 600.

[0022] Further, refer to Figure 1 The first positioning member 210 is a positioning plate provided on the machine 100, which is used to support the lower row of terminals 500. A plurality of positioning pins are installed on the positioning plate to position the lower row of terminals 500. The machine 100 is provided with an outer cover 130 to facilitate the installation and protection of other components. Safety gratings 131 are provided on both sides of the outer cover 130 to improve the working safety of the fixture. A plurality of guide columns 140 are provided along the circumference of the machine 100. The guide columns 140 are connected to the mounting plate 110. The mounting plate 110 can move vertically along the guide columns 140 under the action of a driving member such as a cylinder or a motor, thereby driving the components thereon to move vertically together.

[0023] Furthermore, the third positioning member 310 can move horizontally and vertically relative to the machine 100. Specifically, referring to Figure 8The third positioning member 310 is mounted on the mounting plate 110. During the initial positioning of the terminal 500 and the connector 600, the third positioning member 310 moves vertically upward along with the mounting plate 110, making way for the positioning and installation of the terminal 500 and the connector 600. After the positioning and installation of the terminal 500 and the connector 600 are completed, the third positioning member 310 moves vertically downward along with the mounting plate 110, close to the terminal 500. Thereafter, driven by a driving member such as a motor or a cylinder, the third positioning member 310 moves horizontally relative to the mounting plate 110, moves forward, and is positioned and connected to the upper step 510 of the terminal 500. Furthermore, the fourth positioning member 320 can also move horizontally relative to the machine 100. During the initial positioning of the terminal 500 and the connector 600, the fourth positioning member 320 is located below the terminal 500. After the positioning and installation of the terminal 500 and the connector 600 are completed, the fourth positioning member 320 moves forward, driven by a driving member such as a motor or a cylinder, and is positioned and connected to the lower step 520 of the terminal 500. The state in which the third positioning member 310 and the fourth positioning member 320 perform secondary positioning on the terminal 500 is as follows. Figure 5 and Figure 6 As shown. Further, continue to refer to Figure 6 The third positioning member 310 and the fourth positioning member 320 are both positioning pieces, and the third positioning member 310 and the fourth positioning member 320 both have a comb-shaped plug-in portion 330, and the plug-in portion 330 has a first positioning surface 331 and a second positioning surface 332 that are perpendicular to each other. The first positioning surface 331 and the second positioning surface 332 respectively position the two step surfaces 530 of the fitting terminal 500.

[0024] Further, refer to Figure 8 , a first positioning block 111 is provided on the mounting plate 110. When the mounting plate 110 moves vertically downward, the first positioning block 111 can press against the terminal 500, which can provide further positioning for the terminal 500. The lower row of terminals 500 can be supported and positioned by the first positioning member 210, while the upper row of terminals 500 can be positioned under the pressure of the first positioning block 111, and combined with the positioning of the third positioning member 310 and the fourth positioning member 320 at the front end of the terminal 500, the distance between the two rows of terminals 500 can be fixed, and the relative position with the connector 600 is also kept stable. In the subsequent insertion process, the two rows of terminals 500 are not easy to shake or offset, thereby further reducing the difficulty of insertion. Furthermore, a first buffer block 112 is provided at the bottom of the first positioning block 111, which can provide positioning for the terminal 500 while also preventing the terminal 500 from being damaged.

[0025] Further, refer to Figure 9The second positioning member 220 is a positioning block. The second positioning member 220 is provided with a positioning groove 221. The positioning groove 221 is used to position and place the connector 600, thereby providing preliminary positioning for the connector 600. The bottom wall of the positioning groove 221 is provided with an avoidance groove 222 for the second clamping block to move up and press the lower buckle of the connector 600. Furthermore, a pad 120 is connected to the machine 100 in a horizontally movably manner, and the second positioning member 220 is provided on the pad 120. Driven by a driving member such as a cylinder or a motor, the pad 120 can move horizontally relative to the machine 100, thereby driving the second positioning member 220 thereon to move toward the first positioning member 210, so that the connector 600 moves toward the terminal 500, and finally realizing the insertion of the terminal 500 and the connector 600. In this embodiment, the insertion is achieved by moving the second positioning member 220 toward the first positioning member 210, which can keep the terminal 500 stationary and improve the positioning effect of the terminal 500. Furthermore, a second positioning block 121 is vertically movably connected to the backing plate 120, and the second positioning block 121 can move vertically and press against the connector 600. The second positioning block 121 can be driven by a driving member such as a cylinder or a motor to move toward the connector 600 and press against the connector 600. When the second positioning member 220 drives the connector 600 to move toward the terminal 500 for insertion, the second positioning block 121 can maintain the position of the connector 600 on the second positioning member 220 unchanged, thereby ensuring stable insertion. Furthermore, a second buffer block 122 is provided at the bottom of the second positioning block 121, which can provide positioning for the connector 600 while also preventing the connector 600 from being damaged.
