a housing including at least one socket; and

At least one terminal assembly, which is arranged at the socket, the terminal assembly includes a side terminal and a fixed terminal, the side terminal has a body, the body is provided with a through hole and extends obliquely on one side of the through hole Elastic force arm, the elastic force arm is provided with an insulating protrusion adjacent to the end, the fixed terminal has a folding elastic arm, and an electrical connection with the end of the elastic force arm that can be bent under force is formed at the end of the elastic force arm. contact connection.

According to the above, the connector provides a plug-in group for electronic products. The terminal assembly and connector utilize the design changes of the side terminal and the fixed terminal type, and cooperate with each other to achieve the second common terminal assembly and connector. The functions achieved by the combination of side terminals, fixed terminals and auxiliary terminals, compared with conventional terminal assemblies and connectors, the terminal assembly and connector of the utility model can reduce the setting of auxiliary terminals, and can reduce the original space for auxiliary terminal assembly. The design of the appearance of the connector tends to be more delicate. In addition, the elastic force arm of the side terminal extends obliquely from the body, and is connected to the plug connector through the insulating protrusion to achieve insulation and be pushed by the plug connector. Effectiveness, and this design type can provide better elasticity and reduce the degree of elastic fatigue. In addition, the design of the spring arm in the fixed terminal can also increase elasticity and reduce elastic fatigue, so as to ensure the reliability of electrical connection , thereby improving the service life of the terminal assembly and the connector, so it is more practical and meets the needs of the market.

Detailed ways

Please refer to FIG. 1 to FIG. 3 , which are several preferred embodiments of the terminal assembly and the connector of the present invention. The connector includes a housing 1 having at least one insertion hole 10 and at least one terminal assembly 2 .

The terminal assembly 2 is disposed at the insertion hole 10 of the housing 1, wherein each terminal assembly 2 includes a side terminal 20 and a fixed terminal 30, the side terminal 20 has a body 21, and the body 21 is provided with There is a perforation 22, and an elastic force arm 23 extends obliquely at one side of the perforation 22, and is located on one side of the perforation 22. The side terminal 20 is assembled with an insulating protrusion 24 on the elastic force arm 23 , the insulating bump 24 is adjacent to the end of the elastic arm 23, and the end of the elastic arm 23 is still exposed to the insulating bump 24, wherein the insulating bump 24 is a block with an approximately triangular section , and form a protruding end 25 extending into the insertion hole 10.

The fixed terminal 30 has a folded elastic arm 31, and the fixed terminal 30 forms a connecting portion 32 at the end of the folded elastic arm 31, the connecting portion 32 can be in contact with the end of the elastic arm 23, so that the side terminal 20 is electrically connected to the fixed terminal 30 .

Please refer to Fig. 1 and Fig. 2, the connector provides plug connectors 3 plug groups for electronic products, as shown in Fig. 4, the spring arm 31 of the fixed terminal 30 is located between the elastic arm 23 and the through hole 22 , and the connecting portion 32 of the fixed terminal 30 is not in contact with the end of the elastic arm 23 of the side terminal 20 under normal conditions.

Also as shown in Figure 5, when the plug connector 3 is inserted into the socket 10 of the connector, the plug connector 3 will first contact the protruding end 25 of the insulating bump 24, and push the insulating bump 24 toward the through hole. 22, and the elastic arm 23 moves in the same direction, further making the end of the elastic arm 23 contact with the connection portion 32 of the fixed terminal 30, so that the side terminal 20 is electrically connected with the fixed terminal 30, and The side terminal 20 is in an insulated state because it is connected to the plug connector 3 through the insulating bump 24. When the plug connector 3 is pulled out of the connector, the elastic arm 23 of the side terminal 20 will rebound, so that Its end is separated from the fixed terminal 30 .
