[0004] When the above-mentioned terminal is connected to the external housing, it is difficult to accurately determine the position between the insulating housing and the external housing, resulting in inaccurate plugging position when the conductive metal body is connected to the external housing, affecting the connection efficiency and the conduction efficiency. Summary of the invention

[0005] In order to help solve the problem that it is difficult to accurately judge the relative position between the wiring shell and the external shell during the connection process of the wiring structure with the external shell, which affects the connection efficiency and the conduction efficiency, the present application provides a wiring structure, which adopts the following technical solution: it includes a wiring terminal shell and an external shell, a plurality of conductors are arranged in the wiring terminal shell, and the output ends of the plurality of conductors partially extend out of the wiring terminal shell, a positioning assembly is provided on the wiring terminal shell, and the positioning assembly includes a positioning column arranged on the wiring terminal shell, and a positioning groove matching the positioning column is opened on the external shell, and the positioning column is inserted into the positioning groove at one end facing the external shell.

The use of the positioning component reduces the time for calibrating the relative position of the terminal housing and the external housing, thereby improving the connection efficiency, improving the accuracy of plugging several conductors into the external housing, and reducing the possibility of damaging the conductor and affecting the conductivity efficiency due to the offset of the conductor plugging position.

[0031] The following is combined with Figures 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a wiring structure.

[0033] Reference Figure 1 The wiring structure includes a terminal housing 1 and an external housing. A plurality of conductors 2 are arranged in the terminal housing 1. The output ends of the plurality of conductors 2 partially extend out of the terminal housing 1. In the embodiment of the present application, the number of conductors 2 is three and the three conductors 2 are evenly distributed in the terminal housing 1.

[0034] Reference Figure 1 A positioning assembly is provided on the terminal housing 1, and the positioning assembly includes a positioning column 3 fixedly connected to the terminal housing 1, and a positioning groove matching the size of the positioning column 3 is opened on the external housing. The end of the positioning column 3 facing the external housing is inserted into the positioning groove, and the outer edge of the positioning column 3 is fixedly connected to the limiting block 6.

[0035] Therefore, the limit block 6 limits the depth of the positioning column 3 inserted in the positioning groove. When the positioning column 3 is inserted into the positioning groove to the required position, the limit block 6 will contact the groove wall of the positioning groove, thereby preventing the positioning column 3 from going further in, reducing the possibility of over-insertion of the positioning column 3, and improving the assembly accuracy between the terminal housing 1 and the external housing.

[0036] Reference Figure 1 In the embodiment of the present application, the positioning column 3 is a truncated cone, and the diameter of the truncated cone gradually decreases from the end facing the terminal housing 1 to the end facing away from the terminal housing 1. Therefore, when the truncated cone-shaped positioning column 3 is inserted into the positioning groove, due to the characteristic of its gradually decreasing diameter, it plays a guiding role, which helps to guide the terminal housing 1 and the external housing to be accurately aligned during connection, making the connection process between the terminal housing 1 and the external housing smoother, reducing the difficulty and time of assembly.

[0037] Reference Figure 1The terminal housing 1 is fixedly connected with an anti-fool column 14, and the outer housing is provided with an anti-fool column groove that matches the size of the anti-fool column 14, and the end of the anti-fool column 14 facing the outer housing is partially inserted into the anti-fool column groove. Therefore, when the anti-fool column 14 is successfully inserted along the anti-fool column groove, the terminal housing 1 can be connected to the outer housing in the correct direction, reducing the possibility of installation errors caused by operating errors when the operator connects the terminal housing 1 to the outer housing, and improving the accuracy and stability when the terminal housing 1 is connected to the outer housing.

[0038] Reference Figure 1 The end of the positioning column 3 facing away from the terminal housing 1 is fixedly connected with a guide column 4, and a guide groove matching the size of the guide column 4 is provided on the external housing. The guide column 4 is inserted into the guide groove, and the end of the guide column 4 facing away from the terminal housing 1 is provided with an annular chamfer 5. The design of the annular chamfer 5 provides a smooth transition at the end of the guide column 4, so that the guide column 4 is inserted into the guide groove more smoothly, and can guide the guide column 4 to be gradually inserted along the opening direction of the guide groove, reducing the resistance or damage of the guide column 4 caused by direct collision. Therefore, the guide column 4 plays a guiding role when the terminal housing 1 is connected to the external housing. The guide column 4 is inserted into the guide groove, guiding the positioning column 3 to be quickly inserted into the positioning groove, thereby improving the connection efficiency.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The conductor 2 includes a base 7, a connection hole 8 is provided on the base 7, a conductive sheet 9 is provided on the base 7, and one end of the conductive sheet 9 away from the base 7 extends out of the terminal housing 1. A limiting hole 10 matching the size of the conductive sheet 9 is provided on the terminal housing 1, and the conductive sheet 9 passes through the limiting hole 10. The limiting hole 10 limits the position of the conductive sheet 9, reduces the possibility of position deviation of the conductive sheet 9, and improves the stability of the conductive sheet 9. Therefore, compared with the point contact of the conductive needle in the related art, the conductive sheet 9 can provide a larger contact area, and the structural stability is stronger, while improving the uniformity of conduction, thereby increasing the conduction efficiency.

[0040] Reference Figure 3 and Figure 4, an installation groove 11 matching the size of the base 7 is formed on the terminal housing 1, the base 7 is inserted into the installation groove 11, a positioning piece 12 is fixedly connected to the base 7. In the embodiment of the present application, the positioning piece 12 is disposed opposite to the guiding piece and is located on both sides of the base 7 respectively. A limiting groove 13 matching the size of the positioning piece 12 is formed on the terminal housing 1, and the positioning piece 12 is inserted into the limiting groove 13. Therefore, the installation groove 11 limits the position of the base 7, improving the stability of the base 7 placed on the terminal housing 1. By inserting the base 7 into the installation groove 11, the detachable connection between the base 7 and the terminal housing 1 is realized, with stronger flexibility. The limiting groove 13 limits the position of the positioning piece 12, further improving the stability of the conductor 2 and the base 7 placed on the terminal housing 1.

[0041] The implementation principle of the embodiment of the present application is as follows: When it is necessary to connect the terminal housing 1 to an external housing, one end of the positioning post 3 facing the external housing first contacts the external housing and is inserted into the positioning groove. The positioning post 3 plays a role of pre-positioning to ensure the accuracy of the relative position between the terminal housing 1 and the external housing. Using the positioning component reduces the time for calibrating the relative position between the terminal housing 1 and the external housing, thereby improving the connection efficiency, increasing the accuracy rate of inserting a plurality of conductors 2 into the external housing, reducing the possibility of damage to the conductors 2 and reducing the conduction efficiency caused by the offset of the insertion position of the conductors 2, and improving the conduction efficiency.
