DETAILED DESCRIPTION

The present application is further described in detail below in conjunction with the accompanying drawings.

The embodiment of the present application discloses an electrical connector adapter.

Referring to Figures 1 and 2, the electrical connector adapter includes a base 1 for fixed installation on an electrical component, and a plurality of conductive pins 2 for plugging and matching with the conductive pin tubes inside the socket to be installed are fixedly penetrated in the base 1. The four corners of the base 1 are integrally formed with mounting columns 10, and the length of the mounting columns 10 extends along the length direction of the conductive pins 2. A fastening nut 3 is fixedly set in each mounting column 10, and the fastening nut 3 is coaxial with the respective mounting column 10. The fastening nut 3 is used for the bolts set on the socket to be inserted and tightened in the mounting column 10. By tightening the bolts and the fastening nut 3, the socket that is plugged and matched with the base 1 can be fixed on the base 1.

As shown in Fig. 2 and Fig. 3, a limiting ring 11 is integrally formed on the inner side wall of the mounting column 10, and the limiting ring 11 is coaxially arranged with the fastening nut 3. A limiting groove 30 for pressing the limiting ring 11 is integrally formed on the circumferential outer side wall of the fastening nut 3 toward the limiting ring 11, and the fastening nut 3 is fixed in the mounting column 10 by the mutual crimping between the limiting ring 11 and the limiting groove 30. Two polygonal limiting portions 31 are integrally formed on the outer side wall of the end of the fastening nut 3. In this embodiment, the limiting portions 31 are in the shape of a regular hexagon, and the limiting portions 31 are symmetrically arranged on both sides of the limiting groove 30. The shape of the limiting portion 31 is adapted to the shape of the inner side wall of the corresponding mounting column 10, and the outer side wall of the limiting portion 31 fits with the inner side wall of the mounting column 10.

When the bolt on the socket is screwed into the fastening nut 3, the stability of the fastening nut 3 can be ensured under the limitation of the limiting parts 31 at both ends. During the tightening process, the fastening nut 3 will not rotate synchronously with the bolt, thereby ensuring that the bolt can be smoothly tightened on the fastening nut 3.

As shown in Fig. 2 and Fig. 3, a mounting groove 12 is integrally formed on the outer wall of the base 1 facing the plugging direction of the socket, and a first waterproof pad 4 for pressing against the inner wall of the electrical component is installed in the mounting groove 12. The shape of the mounting groove 12 matches the shape of the first waterproof pad 4, and the first waterproof pad 4 is limited and fixed in the mounting groove 12. When the base 1 is fixedly mounted on the electrical component, the first waterproof pad 4 is pressed against the inner wall of the electrical component, which can further improve the waterproof and dustproof level of the base 1 and enhance the sealing of the mounting surface of the base 1.

As shown in Fig. 2 and Fig. 3, a sealing ring 40 coaxial with the base 1 is integrally formed on the side wall of the first waterproof pad 4 away from the mounting groove 12, and the sealing ring 40 circumferentially surrounds the outside of the plug interface of the base 1. The sealing ring 40 can further block the water flowing down from the top of the base 1, so that the water is not easy to flow into the inside of the base 1. Thereby, the waterproof sealing of the mounting surface of the base 1 can be further improved, and the safety protection level of the base 1 is enhanced.

As shown in Fig. 2 and Fig. 3, a second waterproof pad 5 is also included for fixing on the socket. The structure of the second waterproof pad 5 is the same as that of the first waterproof pad 4, which will not be described here. When the socket and the plug interface of the base 1 are plugged into each other, the second waterproof pad 5 will be pressed against the outer wall of the electrical component. The second waterproof pad 5 can ensure the waterproof sealing of the plug-in surface of the socket and the base 1, further improving the IP waterproof level of the plug-in surface of the two.

As shown in Figures 2 and 3, a retaining ring 6 is inserted and fixed on the side wall of the base 1 facing away from the first waterproof pad 4. The retaining ring 6 circumferentially surrounds the conductive pin 2 extending from the end of the base 1 facing away from the first waterproof pad 4. The retaining ring 6 is used to enclose the conductive pin 2, thereby effectively reducing the probability of the conductive pin 2 being bent and broken due to external collision, thereby improving the protection effect of the conductive pin 2.

The implementation principle is: after the base 1 is fixedly installed on the electrical component, the matching socket is inserted into the base 1, and it is ensured that the conductive pin 2 inside the base 1 is plugged into the conductive pin tube inside the socket. At this time, the socket establishes a signal connection with the base 1, and finally the bolt is screwed in to the position of the fastening nut 3, and the installation of the socket is completed after tightening. The waterproof seal between the base 1 and the inner wall of the electrical component is ensured by the first waterproof pad 4. The waterproof seal between the socket and the base 1 can be ensured by the second waterproof pad 5, further improving the IP waterproof rating of the plug-in surface of the two. When maintenance is required inside the socket, the maintenance personnel do not need to open the inside of the electrical component. They only need to unscrew the bolts from the respective fastening nuts 3 in turn, and then the socket can be removed from the base 1 smoothly, which facilitates maintenance and reduces the workload during maintenance.

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.
