[0023] Embodiment 1

[0024] Since the existing plug-in terminal has the problem of unstable connection, the structure of the plug-in terminal is redesigned, and a plug-in terminal for MR16 lamp is designed, and the specific scheme is as follows:

[0025] As shown in Figures 1-3 , a plug-in terminal for MR16 lamp, comprising: an insulating body 1, a conductive pin and an auxiliary fixing structure, the conductive pin is a copper alloy pin, the auxiliary fixing structure is arranged on the insulating body 1, the auxiliary fixing structure is provided with a positioning groove and a positioning protrusion 104, which can enhance the connection stability of the plug-in terminal and the lamp and the power supply, ensure the stable light emission of the lamp, and the two ends of the conductive pin are provided with a narrowing structure, so as to facilitate faster plug-in.

[0026] The copper alloy pin can significantly reduce the resistance, reduce the energy loss and heat generation, improve the conduction efficiency, and reduce the safety hazard.

[0027] As shown in Figure 1 , 2 , the auxiliary fixing structure and the insulating body 1 are of an integral structure, which ensures the strength of the structure, the auxiliary fixing structure and the insulating body 1 are of an integral structure, which not only ensures the structural strength, but also reduces the processing difficulty, and can be integrally formed by using a precision injection mold, without the need for additional processing and assembly.

[0028] As shown in Figure 1 , 2As shown, the insulating body 1 is provided with a columnar structure 103 extending to the front end of the conductive pin to improve the strength of the conductive pin. Since the length of the conductive pin is relatively long, the columnar structure 103 can improve the strength of the conductive pin and prevent the conductive pin from being easily deformed. At the same time, the area that can be pinched by fingers is increased, making it more convenient to hold the plug-in terminal.

[0029] As shown in Figure 1 , 2 , the insulating body 1 is provided with a positioning groove 102 in the length direction, and the insulating body 1 is provided with a positioning groove 102 on both sides. The structure can be conveniently connected with the positioning groove 102 to complete the buckling connection and improve the connection stability.

[0030] As shown in Figure 1 , 2 , one side of the positioning groove 102 is provided with a positioning protrusion 104. In this embodiment, the positioning protrusion 104 is a triangular prism structure, which extends inward from the inner wall of one side of the positioning groove 102. After the external structure is buckled in the positioning groove 102, the length direction can be prevented from shifting in this direction through the positioning protrusion 104.

[0031] The combined design of the positioning groove 102 and the positioning protrusion 104 can control the gap between the plug-in terminal and the lamp and the power supply within a very small range, and can withstand a certain torque without displacement.

[0032] As shown in Figure 1 , 2 , the insulating body 1 is made of high-temperature-resistant and high-strength engineering plastic. The insulating body 1 is in a "U" shape structure, and the insulating body 1 is provided with a stepped structure 101. The insulating body 1 is in a U-shaped structure, which is convenient for the fingers of the staff to hold. The fingers can pinch the insulating body 1 and then perform plug-in connection of the plug-in terminal, which is more convenient for assembly and disassembly. The stepped structure 101 can increase the friction when the insulating body 1 is pinched, which is more convenient for plug-in connection in the plug-in direction.

[0033] As shown in Figure 3 , the conductive pin is in a "Z" shape structure, which can be used to connect different structures at both ends of the plug-in terminal. In this embodiment, the conductive pin is used to connect different components at both ends. The Z-shaped structure realizes the double-end different distance connection of the conductive pin, that is, the distance between the two ends of the conductive pin is different, which meets the plug-in requirements of both ends.

[0034] The narrowing structure is any one of a conical structure, a circular truncated cone structure 202 or a spherical body structure 201. In this embodiment, one end of the conductive pin is a circular truncated cone structure 202, and the other end is a spherical body structure 201, which can both play a guiding role in plug-in connection, making both ends faster in plug-in connection.

[0035] The plug-in terminal of the scheme, both ends of the conductive pin 2 are provided with a narrow structure, which is more convenient for the conductive pin to be quickly plugged in, improves the efficiency of assembly connection, the conductive pin 2 made of copper alloy has excellent conductivity and mechanical properties, the auxiliary fixing structure is provided on the insulating body 1 and is an integral structure with the insulating body 1, which ensures the use strength, when the plug-in terminal is connected, the stability of connection can be enhanced through the auxiliary fixing structure, the reliability of the lamp is improved, and the failure rate is reduced.

[0036] Embodiment 2

[0037] In this embodiment, the structure of the plug-in terminal is basically the same as that of embodiment 1, the difference lies in that the connection parts of the conductive pin 2 and the insulating body 1 are all provided with a 0.1mm silica gel shock absorbing ring, which is used to reduce the vibration of the connection terminal and improve the connection stability.

[0038] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not the limitation of the embodiments of the utility model. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or changes can be made. Here, it is not necessary and impossible to enumerate all the embodiments.
