Electric conector provided with locking mechanism

Abstract

The invention provides an electrical connector provided with a locking mechanism for mitigating an impact force of a locking arm. The plug connector (10) is provided with a housing (1), a plurality ofcontacts (3) and a locking arm (5). A contact (3) is arranged inside the housing (1). An intermediate portion of the locking arm (5) is supported on a support portion (11) protruding from an outer wall surface of the housing (1). The locking arm (5) has a hook portion (5h) at one end and a semicircular finger portion (5f) at the other end. The finger portion (5f) has a concave portion (52c) and an inclined surface (52s). The concave portion (52c) is arranged on the other end portion in a manner of facing one end portion of the locking arm (5). The inclined surface (52s) is inclined at the other end of the locking arm (5) in a manner that one end close to one end of the locking arm (5) is away from the outer wall surface (11w) of the housing (1). The inclined surface (52s) is capable of generating a component force from a force in the insertion direction from the other end portion of the locking arm (5) to the plug connector (10).

Description

technical field [0001] The present invention relates to electrical connectors with locking mechanisms. In particular, it relates to a structure of an electrical connector having a locking mechanism that integrally holds the mating connector after being engaged with the mating connector. Background technique [0002] For example, as an electrical connector, among wire-board connectors, a cable can be electrically connected to a printed circuit board by connecting a plug connector attached to a terminal of the cable and a base connector mounted on a printed circuit board. . In such a wire-board connector, a manually operated locking mechanism is provided between the housings so that the plug connector is integrally held by the base connector. [0003] As such a locking mechanism, a lever-type locking mechanism is known. In the lever-type lock mechanism, a lock arm has a hook portion at one end and a finger portion at the other end, and the middle portion of the lock arm is ...

Problems solved by technology

However, in this case, since the cushioning material is required and the work of packing the connector part with the cushioning material is required, packing costs will be incurred, and there is a problem that it will increase the cost of manufacturing the connector with electric wires.
