Embodiment Construction

[0042] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0043] A first embodiment of the present invention is described with reference to FIGS. 1-17. In FIG. 1, reference numeral 1 denotes a male connector housing which is directly connected to an electric device. The male connector housing 1 is substantially in the shape of an angled tube, its front portion is open, and a male terminal fitting m is accommodated therein. A stop protrusion 2 protrudes from the upper surface of the housing, the protrusion 2 is located close to the front edge thereof. A pair of flanges 3 are provided on both sides of the stopper protrusion 2 . These flanges 3 extend from the opening edge of the male connector housing 1 to the rear edge of the stopper protrusion 2 in a parallel manner.

[0044] In addition, a pair of guide protrusion edges 4 are formed on both side surfaces of the male connector housing 1 in order to prevent twisting wh...

Abstract

When two connector housings are half fitted together, a fitting detecting connector causes one of the connector housings to be pushed in a direction of separation by means of springs which are provided within a female connector housing 5, a spring holder 15 being inserted into this female connector housing 5 so that it can move in an anterior-posterior direction. This spring holder 15 houses coiled springs 16 and, when the two connector housings are being fitted together, a locking arm 11 rises over a stopping protrusion 2. As a result of this rising up the spring holder 15 is engaged, its movement in a posterior direction is regulated, and the coiled springs 16 are compressed. When the connector housings are completely fitted together the locking arm 11 again moves, releasing the engagement of the spring holder 15, and the spring holder 15 is pushed in a posterior direction by the spring force. In this way the separating force does not act when the connector housings are fully engaged.

Description

technical field [0001] The invention relates to an electrical connector capable of assembly detection. Background technique [0002] A traditional assembly detection connector includes two parts, a male connector and a female connector. When the fitting operation of the male and female connectors is performed, a spring built into one of the connector housings is compressed. If the fitting operation is stopped before the two connector housings are completely fitted together, the corresponding connector housings are pushed out by the springs, which alerts the operator that correct fitting has not been achieved. [0003] However, in the fully assembled state, the spring force still continues to act, so that the force to separate the two housings is always applied, which is not desirable. Therefore, the connector is designed so that the spring is in a compressed state during the assembly operation, and the spring returns to its uncompressed state when the assembly is complete....
