Contact piece and plug and socket with the contact piece

technical field

The utility model relates to the technical field of electrical connectors, in particular to a contact piece and a plug and a socket with the contact piece.

Background technique

For some existing electrical connector products, the high-frequency contacts need additional fixing parts such as positioning springs and snap rings after they are installed in the connector, and special removal tools are required for removal, resulting in the use of plugs or The assembly and disassembly of the socket is relatively cumbersome.

Utility model content

The purpose of the utility model is to provide a contact piece which can be self-positioned and removed without using other tools, and at the same time provide a plug and socket which are easy to assemble and disassemble with the contact piece.

The technical solution of the contact piece of the utility model is: a contact piece, including a contact piece body composed of a pin body or a socket body, a fixed ring is fixedly set on the contact piece body, and the head end of the fixed ring can be radially The retracted claw has a radial gap between the claw and the body of the contact piece. Each finger end of the claw has an everted edge corresponding to the stop-retraction of the connector housing. The body of the contact is equipped with a fixed The claw end of the ring is opposite to the top-mounted cone annulus, and the end of the cone annulus is smaller than the ring formed by the corresponding claws. The contact body is provided with a connector at the rear of the cone The backstop matches the corresponding steps.

The body of the contact piece is provided with a locking ring top mounted on the tail end of the fixing ring, so that the fixing ring is clamped and fixed between the cone ring surface and the locking ring.

The claw fingers of the claw portion of the fixing ring are evenly distributed along the circumference.

The technical solution of the plug of the utility model is: a plug, including a plug housing and a contact piece inserted in a contact socket, and the contact piece includes a contact piece body composed of a pin body or a socket body. A fixed ring is fixed on the body of the contact, and a ring groove corresponding to the position of the fixed ring is provided in the socket of the contact. The head end of the fixed ring is a radial retractable claw, and the gap between the claw and the contact body is A radial gap is left, and each claw finger end of the claw has an eversion edge corresponding to the ring groove in the socket of the contact piece of the plug housing. The top-mounted cone ring surface, the end of the cone ring surface is smaller than the ring formed by the corresponding claws, and the contact body is provided with a contact socket with the plug housing at the rear of the cone ring surface The ring groove in the back fits the corresponding step.

The contact piece on the plug is provided with a locking ring top mounted on the tail end of the fixing ring, so that the fixing ring is clamped and fixed between the cone ring surface and the locking ring.

The claw fingers of the claw portion of the fixing ring are evenly distributed along the circumference.

The technical solution of the socket of the utility model is: a socket, including a socket housing and a contact piece inserted in a contact socket, and the contact piece includes a contact piece body composed of a pin body or a socket body. A fixed ring is fixed on the body of the contact, and a ring groove corresponding to the position of the fixed ring is provided in the socket of the contact. The head end of the fixed ring is a radial retractable claw, and the gap between the claw and the contact body is A radial gap is left, and each claw finger end of the claw has an eversion edge corresponding to the ring groove in the contact socket of the socket housing. The top-mounted cone ring surface, the end of the cone ring surface is smaller than the ring formed by the corresponding claws, and the contact body is provided with a contact socket with the socket housing at the rear of the cone ring surface The ring groove in the back fits the corresponding step.

The body of the contact piece on the socket is provided with a locking ring top mounted on the tail end of the fixing ring, so that the fixing ring is clamped and fixed between the cone ring surface and the locking ring.

The claw fingers of the claw portion of the fixing ring are evenly distributed along the circumference.

When the contact piece of the utility model is pushed into the contact piece socket of the connector, the claw portion of the fixed ring head on the contact piece can match with the positioning ring groove in the contact piece socket, and when the claw portion opens in the positioning ring groove After opening, you can hear a click sound, which means that the contact piece is assembled in place. At this time, the contact piece is fixed in two ways. When the contact piece is pulled backward, the conical ring surface of the contact piece pushes into the inner ring mouth enclosed by the claw portion of the fixed ring, forcing the claw fingers to open. The greater the pulling force, the larger the radial opening range of the claw fingers , so that the buckling force of the eversion edge on the claw finger is greater, so that the contact piece cannot be pulled out. When removing and dismounting, only the outer and rear fixing ring is needed. Because there is a radial gap between the fixing ring and the contact body, the eversion edge of the claw finger of the fixing ring claw will shrink inward under force, and the contact piece can be pulled out for connection. device; therefore, the contact piece of the utility model does not need additional fixing parts such as positioning springs and snap rings after being loaded into the connector, and no removal tool is required for removal and removal, and the disassembly and assembly are very convenient.
