[0028] When using the matching device of the wiring harness connector terminal and the molded shell, if Figure 1-Figure 6 As shown, firstly, the wire 5, the metal terminal 6 and the plastic shell 9 are installed. The inclined structure at the upper end of the elastic clip 403 can facilitate the sliding between the wire 5 and the elastic clip 403. With the elastic effect of the elastic clip 403, the clamping and limiting effect of the wire 5 can be achieved to ensure the stability of the installation of the wire 5. At this time, the metal terminal 6 contacts the outer wall of the elastic clip 403 to achieve positioning, thereby achieving the installation of the wire 5 and the metal terminal 6. Then, the plastic shell 9 is matched with the slot on the assembly seat 801 to achieve the positioning of the plastic shell 9. At this time, the plastic shell 9 contacts the push plate 805, and the plug on the plastic shell 9 is nested in the opening on the push plate 805, and at this time, the plastic shell 9 is The connector is not connected to the socket 803, so that the plastic shell 9 is installed. After the wire 5, the metal terminal 6 and the plastic shell 9 are installed, the cylinder 2 is controlled to extend, thereby driving the fixed plate 3, the mounting plate 401, the mounting seat 402, the wire 5 and the metal terminal 6 to move. The sliding guide between the fixed plate 3 and the crossbar 301 can ensure the stability of the movement of the fixed plate 3. When the mounting plate 401 contacts the vertical plate 701, the positioning of the mounting plate 401 is achieved. At this time, the central axis of the metal terminal 6 coincides with the central axis of the mounting hole on the plastic shell 9, ensuring that the metal terminal 6 and the plastic shell 9 can be assembled normally in the later stage, thereby realizing the automatic feeding of the metal terminal 6;

[0029] A push rod 702 is slidably connected to the vertical plate 701, and the lower end surface of the push rod 702 is higher than the lower end surface of the fixed plate 3, and the right end of the push rod 702 is fixed to one end of the second spring 703, and the other end of the second spring 703 is fixed to the workbench 1; the push rod 702 is rotatably connected to one end of the connecting rod 704, and the other end of the connecting rod 704 is rotatably connected to the assembly seat 801, and the connecting rod 704 is symmetrically distributed front and back about the center line of the workbench 1;

[0030] When the mounting plate 401 contacts the vertical plate 701, the top rod 702 contacts the fixed plate 3 synchronously. Figure 1-Figure 6 As shown, the control cylinder 2 continues to extend, so that the fixed plate 3 moves relative to the mounting plate 401, and the sliding guide effect between the slide bar 404 and the fixed plate 3 can ensure the stability of the movement of the fixed plate 3. At this time, the fixed plate 3 moves to push the top rod 702 to move to the right, and the transmission effect of the connecting rod 704 is cooperated, so that the front and rear assembly seats 801 move toward each other, and the sliding guide effect between the assembly seat 801 and the guide rail 802 can ensure the stability of the movement of the assembly seat 801, so that the plastic shell 9 on the assembly seat 801 is assembled to the metal terminal 6, and the plastic shell During the assembly process of the plastic shell 9 and the metal terminal 6, the elastic action of the third spring 807 provides a force for the push plate 805, which can ensure that the plastic shell 9 does not move temporarily, so that the plastic shell 9 and the metal terminal 6 are normally assembled. When the assembly seat 801 moves to make the plastic shell 9 contact with the mounting plate 401 and exert a force, the plastic shell 9 is forced to move, so that the plug on the plastic shell 9 is plugged into the socket 803, and the movement of the plastic shell 9 causes the push plate 805 to move synchronously under the force, and the sliding guide effect between the guide rod 806 and the assembly seat 801 can ensure the stability of the movement of the push plate 805. At this time, the third spring 807 is forced to shrink until the push plate 805 contacts the assembly seat 801 to achieve limit. At this time, the plug on the plastic shell 9 is completely plugged into the socket 803, and the plastic shell 9 is completely assembled with the metal terminal 6, so that the two sockets 803, the plastic shell 9, the metal terminal 6 and the wire 5 form an electric circuit. When there is no problem with the plastic shell 9, the metal terminal 6 and the wire 5, the electric circuit operates normally and the indicator light 804 lights up. When there is a problem with the plastic shell 9, the metal terminal 6 and the wire 5, the indicator light 804 is not lit, so that automatic detection can be achieved. And after the detection is completed, the cylinder 2 contracts and drives the fixed plate 3 to reset. At this time, the assembly seat 801 is forced to move to both sides, and the elastic action of the third spring 807 makes the push plate 805 automatically reset. Through the action of the push plate 805, the plastic shell 9 can be pushed to move, so that the plastic shell 9 is separated from the socket 803. When the assembly seat 801 is reset, the plastic shell 9 is separated from the groove on the assembly seat 801 to facilitate the reset of the fixed plate 3 and the feeding mechanism 4, thereby completing the assembly detection of the connector. This is the working principle of the matching device of the wiring harness connector terminal and the plastic shell.
