DESCRIPTION:
BRIEF SUMMARY
FIELD OF INVENTION
This invention relates to electrical connectors and a connector to which a cam member is attached. In particular, it relates to connectors with cam members whose housings can be completely engaged by little force with the housing of a mating connector by manipulating the slide-type cam member.
BACKGROUND OF THE INVENTION
This sort of connector with a slide-type cam member is configured like the connectors disclosed in Japanese UM Publication No. 6-11275 and No. 6-54255, for example, so that the housing can be completely engaged with the housing of a mating connector by sliding or moving the cam member from a first and open position, from which the cam member can be connected with the housing of the mating connector that is in a temporarily engaged position, to the closed position, whereby the cam member is moved into a position at which it completely engages with the housing of the mating connector.
In order to correctly carry out the task of connection with a mating connector, it is preferable that the worker is able to quickly verify that the cam member has moved completely to the closed position. However, with the conventional connectors that are provided with a cam member, it has been difficult for workers to confirm whether or not the cam member has completely moved to the closed position. Consequently, performing the connection has been difficult, and there was also a high probability that the connection ended without the cam member sliding to the closed or connected position. In particular, there have been cases, depending on the technical field, such that the worker groped around to make the two connectors connect and this made it all the more difficult for the worker to verify that the cam member had moved to the completely closed position.
In view of the situations described above, the object of this invention is to provide a connector with a cam member that enables the worker to quickly and correctly verify that the slide-type cam member was moved to the completely closed or connected position and that the connection with the mating connector was properly made.
An electrical connector assembly is disclosed in U.S. Pat. No. 4,596,771 and comprises first and second connector housings and a camming slide for mating and unmating the housings. The first housing has flanges extending from the mating face thereof and has slots in the flanges which receive cam followers on the cam slide. The second housing has cam tracks in its sidewalls which also receive the cam follows. The camming slide has a web which is spaced from the rear face of the second housing and arms which extend from the web across the sidewalls of the second housing and which overlap the flanges on the first housing. The cam followers project from the internal surfaces of the arms and extend through the slots and are dimensioned to be received in the camming slots on the second housing. Recessed surfaces are located an the inner surfaces of the arms and projections are provided at left hand ends of the recesses which ride over projections on the flanges thereby retaining the camming slide in position when the housings are at a mated condition.
An electrical connector housing assembly is also disclosed in U.S. Pat. No. 5,244,400 which comprises a male housing, a female housing in which the male housing is movably fitted, a cam member is movably fitted on the female housing so that the cam member can be moved relative thereto in order to fasten both housings together, and a detecting member being provided on the cam member and the female housing for detecting whether both housings are completed mated to each other.
In order to achieve the aforementioned objective, a connector assembly with a cam member of the present invention comprises connectors whose housings can be completely engaged by sliding a slide-type cam member attached to one of the housings from a first position to a closed position, wherein the cam member is provided with a resilient latch, which is positioned outsides of the housing.
