Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a cover plate structure of a connector. Background Art

[0002] Connectors are devices used to connect wires or circuits. They are used to connect wires to wires, wires to devices (such as circuit boards, plugs or sockets), and circuits to transmit signals or power. Connectors are used to connect various types of electrical and electronic equipment;

[0003] After checking the public (announcement) number: CN216289251U, a wiring harness connector with a cover plate that is easy to maintain is disclosed. This technology discloses "including a connector housing with an open top structure, a plurality of wire tubes are fixedly installed on the left outer wall of the connector housing at equal intervals, and the plurality of wire tubes are hollow structures. One end of the plurality of wire tubes extends into the connector housing, and wires are passed through the plurality of wire tubes. A plug connector is fixedly installed on the right outer wall of the connector housing, and a plug slot is provided on the side of the plug connector away from the connector housing. A plurality of conductive strips are fixedly installed in the plug slot at equal intervals, and one end of the plurality of conductive strips extends into the connector housing.
