Connector capable of self-locking

Abstract

A connector capable of being self-locked comprises a shell, at least two terminals are arranged in the shell, a sliding block and an elastic piece are arranged at the position, corresponding to any terminal, in the shell, and the sliding block abuts against the interior of the shell under the elastic force effect of the elastic piece and blocks a wiring port, used for being connected with a wire terminal in an inserted mode, in the shell. The elastic protrusions are arranged on the sliding blocks, and when the connector is inserted, the elastic protrusions are extruded and contracted, so that the sliding blocks are released from the clamping state. When the connector is not inserted into equipment, the lead terminal cannot be inserted into the connector, so that the connector is prevented from being inserted into the equipment in a live-line manner; if the wire terminals are not removed, the connector cannot be pulled out from the equipment, so that electric arcs are prevented from being generated during pulling out; therefore, hot plugging of the connector can be avoided, electric arcs are prevented from being generated in the plugging process of the connector, and damage of the electric arcs to equipment and the connector is avoided. The connector fundamentally avoids the generation of the electric arc instead of the conventional weakening of the electric arc, and can be applied to wider occasions.

Description

technical field [0001] The invention relates to a connector, in particular to a self-locking connector. Background technique [0002] At present, the commonly used method of plugging and unplugging the connector and the device port is that the connector is first locked and then plugged into the device port. After the connector is locked and plugged in under live conditions, due to the existence of the arc, it will cause damage to the device port contact or the connector contact. In the process of plugging and unplugging, if the connector contact is damaged due to arc burning, you can consider replacing it with a new connector. However, if the device port contact is burnt, it is often inconvenient to replace, and the overall equipment value is more expensive. cause greater losses. Therefore, there is a need for a self-locking connector, which can be inserted into the port of the equipment cabinet when there is no locking wire, that is, the connector is in an open circuit st...
