Description

Direct-insertion push-pull self-locking connector

Technical Field

The utility model relates to a heavy current connector processing field, concretely relates to cut straightly push-and-pull self-locking connector.

Background

Current connectors are indispensable components in electronic devices, and the current of a power supply needs to realize a load through the connectors.

The Y27 series electric connector in the current market has certain defects, and the push-pull self-locking function enables the series electric connector to be plugged and unplugged quickly, but the structure is complex.

Some critical dimensions of the electrical connector will cause chain reaction if they vary, and other dimensions may fail. For example, the position of a seven-shaped groove on the plug shell, the positions of the seven-shaped groove and a clamping cap positioning screw hole, the relative positions of the plug shell marble loosening and the locking groove and the position of the socket shell end surface to the marble locking groove are controlled by the clamping cap positioning screw hole and the front end of the clamping cap. The error of production and processing causes that the electric connector can not be pulled out after being plugged or the plug loosens and falls after being plugged. When the connector is used for connecting a system, the reliability is insufficient, the safety factor is low, the current carrying capacity is not high, the current transmission is influenced, the plugging times are too few, and the service life of equipment is shortened.
