[0020] By adopting the above technical solution, the staff can press the connecting plate to plug and fix the two locking plates to the terminal body at one time, so as to facilitate the staff to replace the wiring harness. At the same time, the connecting plate abuts against the terminal body, so that the connecting plate has a limiting effect on the locking plate, which can reduce the occurrence of the locking plate not being plugged in properly or being over-plugged.

[0021] Optionally, a plurality of anti-slip ridges are provided on a side of the connecting plate away from the terminal body, and the anti-slip ridges are arranged at intervals.

[0022] By adopting the above technical solution, when the staff pushes the connecting plate, the anti-slip convex strips increase the force application point for the staff, so that the staff can plug and fix the locking plate and the terminal body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] The following is combined with Figure 1-8 This application is described in further detail.

[0037] Example 1

[0038] The present application embodiment discloses a wiring terminal. Figure 1 The wiring terminal comprises a terminal body 1 and a locking structure 2, wherein the locking structure 2 is plugged and fixed to the terminal body 1.

[0039] Reference Figure 1 The terminal body 1 includes an integrally formed wiring terminal 11, a connecting section 12 and a plug-in terminal 13. Figure 2 and Figure 3The connection terminal 11 is provided with a plurality of penetration channels 14 for the wiring harness 3 to be plugged in. The penetration channels 14 penetrate the connection section 12 and extend to the plug-in terminal 13 .

[0040] Reference Figure 3 and Figure 4 The side wall of the connecting section 12 is provided with an abutting groove 15, which is connected to the penetration channel 14, and the wiring harness 3 in the penetration channel 14 is partially arranged in the abutting groove 15. The plug-in end 13 of the terminal body 1 is embedded with a conductive member 4 that abuts against the electrical device, and the wiring harness 3 penetrates the penetration channel 14 and is connected to the conductive member 4.

[0041] Reference Figure 4 In this embodiment, the abutment groove 15 is arranged near the plug end 13. In this embodiment, the conductive sheet is a metal spring sheet, and the metal spring sheet is partially arranged in the penetration channel 14. After the outer insulation layer is removed from the end of the wire harness 3, the end of the wire harness 3 is overlapped with the conductive sheet.

[0042] Reference Figure 2 and Figure 3 A first plugging slot 16 is provided on the side of the wiring terminal 11 close to the connecting section 12, and a second plugging slot 17 is provided on the side of the plugging terminal 13 close to the connecting section 12. The first plugging slot 16 and the second plugging slot 17 are arranged opposite to each other; the locking structure 2 is plugged between the first plugging slot 16 and the second plugging slot 17.

[0043] Reference Figure 5 The locking structure 2 includes a locking plate 21, a connecting plate 22 and an elastic member 23 which are arranged opposite to each other. The connecting plate 22 is arranged between the two locking plates 21, and the two ends of the connecting plate 22 are connected to the ends of the locking plates 21. The connecting plate 22 and the locking plates 21 are combined into a groove structure; in this embodiment, the connecting plate 22 and the locking plates 21 are integrally formed. Therefore, the staff can press the connecting plate 22 to plug and fix the two locking plates 21 to the terminal body 1 at one time, so that it is convenient for the staff to replace the wiring harness 3. At the same time, the connecting plate 22 abuts against the terminal body 1, so that the connecting plate 22 has a limiting effect on the locking plate 21, which can reduce the occurrence of the situation where the locking plate 21 is not plugged in or over-plugged.

[0044] Reference Figure 5 The connecting plate 22 is provided with a plurality of anti-skid convex strips 221 on one side away from the terminal body 1, and the anti-skid convex strips 221 are arranged at intervals. When the staff pushes the connecting plate 22, the anti-skid convex strips 221 increase the force application point for the staff, so that the staff can plug and fix the locking plate 21 with the terminal body 1.

[0045] Reference Figure 2 and Figure 3 In this embodiment, the locking plate 21 is inserted between the first inserting groove 16 and the second inserting groove 17 , and the connecting plate 22 is in contact with the terminal body 1 .

[0046] Reference Figure 2 and Figure 5 The locking plate 21 is provided with an abutting convex strip 24 on one side close to the connecting section 12. The abutting convex strip 24 is provided on the side close to the second plug-in slot 17, and the abutting convex strip 24 is inserted into the abutting slot 15. The abutting convex strip 24 is used to squeeze and fix the wire harness 3. After the staff installs the wire harness 3 in the insertion channel 14, the locking plate 21 is plugged and fixed with the terminal body 1; thereby, the abutting convex strip 24 squeezes and fixes the wire harness 3, so that the wire harness 3 is fixedly connected with the terminal body 1.

[0047] Reference Figure 3 At the same time, the side wall of the second plug-in slot 17 away from the connecting section 12 is provided with a plurality of avoidance notches 171, and the avoidance notches 171 are arranged at intervals; and the avoidance notches 171 are arranged on both sides of the penetration channel 14. By providing a plurality of avoidance notches 171 in the second plug-in slot 17, when the locking plate 21 is plugged into the second plug-in slot 17, the contact area between the side wall of the slot and the locking plate 21 can be reduced, so that it is convenient for the staff to plug the locking plate 21 into the second plug-in slot 17. At the same time, the avoidance notches 171 are arranged on both sides of the penetration channel 14, so that the side wall of the second plug-in slot 17 is located directly above the penetration channel 14; the side wall of the second plug-in slot 17 has a limiting effect on the abutting convex strip 24, so as to improve the squeezing effect of the abutting convex strip 24 on the wiring harness 3.

[0048] Reference Figure 5 The locking plate 21 is provided with an escape groove 211 on one side close to the first plug-in slot 16, and an elastic member 23 is arranged in the escape groove 211. One end of the elastic member 23 is fixedly connected to the side wall of the escape groove 211, and the other end of the elastic member 23 is provided with an abutment block 25. The abutment block 25 protrudes out of the escape groove 211, and the abutment block 25 is used to abut against the bottom wall of the first plug-in slot 16.

[0049] Reference Figure 6 and Figure 7 When the staff inserts the locking plate 21 between the first plug-in slot 16 and the second plug-in slot 17, the side wall of the first plug-in slot 16 abuts against the abutment block 25, thereby forcing the elastic member 23 to move toward the side close to the locking plate 21; thereby utilizing the elastic force of the elastic member 23 itself to improve the connection strength between the locking plate 21 and the terminal body 1, thereby improving the stability of the operation of the terminal block.

[0050] At the same time, a connecting notch 161 is provided on the side wall of the first plug-in slot 16 away from the connecting section 12. When the locking plate 21 is plugged and fixed to the terminal body 1, the abutment block 25 is arranged opposite to the connecting notch 161, and there is an avoidance gap between the abutment block 25 and the side wall of the connecting notch 161. When the staff replaces the wiring harness 3, the staff can use a special tool to insert between the side wall of the connecting notch 161 and the abutment block 25 to force the abutment block 25 to move toward the locking plate 21, thereby facilitating the staff to remove the locking plate 21.

[0051] Example 2

[0052] The difference between this embodiment 2 and embodiment 1 is that:

[0053] Reference Figure 8 The bottom wall of the first groove is provided with a plurality of arc-shaped protrusions 162 at intervals, and the arc-shaped protrusions 162 are arranged on the moving path of the abutment block 25. Therefore, when the locking structure 2 is plugged and fixed with the terminal body 1, the arc-shaped protrusions 162 have a limiting effect on the abutment block 25, thereby further improving the connection stability between the locking structure 2 and the terminal body 1.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
