Problems solved by technology
There are following problems in the existing fixing form of this contact piece: in the prior art, the contact piece needs to be assembled on the front insulator part before the rear insulator part is loaded into the housing, and the insulator must be assembled on the housing before leaving the factory Therefore, it is necessary to assemble the contact piece into the insulator before leaving the factory. In order to allow the manufacturer using the connector to press the wire smoothly, the end of the contact piece needs to reserve enough crimping length, and the contact piece needs to be extended to cause the connection The volume of the device is too large, and the crimping process is inconvenient

Embodiment Construction
[0021] An example of a connector is Figure 2~9 As shown: it includes a housing (not shown in the figure), an insulator disposed in the housing, and a contact piece 3 whose front end is a plug-in terminal. The fixing structure of the housing and the insulator is the same as that of the prior art, and will not be detailed here. As mentioned above, the front end of the contact piece is the plug end. The outer periphery of the contact piece 3 is provided with a mounting boss 11. The insulator includes a front insulator part 1 and a rear insulator part 2 which are separately arranged at the front and back. The front insulator part 1 is provided with an initial installation groove 7, and the rear insulator part 2 is provided with a The stop ring platform 8 on the rear side of the installation groove, the stop ring platform is provided with a boss passing through the groove 9 extending along the front and rear direction and corresponding to the initial installation groove 7, and the...

The invention relates to a connector. The connector comprises a casing, an insulator and a contact piece, wherein the insulator is arranged in the casing, and the front end of the contact piece is a plugging end. The periphery of the contact piece is provided with an installation boss, the insulator is provided with an initial installation groove into which the installation boss can be mounted from back to front, the insulator is also provided with a final installation groove which is arranged separatedly from the initial installation groove in the circumferential direction, a rotation channel through which the final installation groove is connected with the initial installation groove is arranged between the final installation groove and the initial installation groove, the rotation channel is internally provided with an elastic unidirectional passing structure, the installation boss rotates from the initial installation groove to the final installation groove via the elastic unidirectional passing structure, the elastic unidirectional passing structure prevents the installation boss from rotating from the final installation groove to the initial installation groove, and the final installation groove includes front and back groove walls which are in stopping cooperation with the front and back ends of the installation boss and limit front and back movement of the installation boss. The contact piece can be assembled in the insulator after the insulator is assembled in the casing.
Description
technical field [0001] The invention relates to a connector for signal transmission. Background technique [0002] The existing connector includes a shell and an insulator arranged in the shell. The insulator is provided with a contact piece, and the insulator plays a role in fixing and maintaining the contact piece. In order to realize the fixing of the contact piece, the existing insulator and the contact piece The matching structure of the parts is as figure 1 As shown: the insulator includes a front insulator part 1 and a rear insulator part 3 which are arranged separately at the front and back. The front insulator part 1 is provided with a front stop surface for blocking and cooperating with the contact piece 2 to limit the forward movement of the contact piece. The rear insulator part Part 3 is provided with a rear stop surface used to stop and cooperate with the contact piece to limit the backward movement of the contact piece. After the contact piece is installed on...
