BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to connector technology and more particularly, to a connector module, which has claws arranged in a connection housing for securing a lead wire holder assembly to facilitate the assembly process.
2. Description of the Related Art
With the continuous updating of electronic technology, electronic innovative products have been continuously created. Various electronic products are connected to other electronic devices by cable with mating male and female connectors for signal transmission.
A male or female connector generally comprises a connection housing, and a guide tube mounted in the connection housing to hold lead wires for conduction. The connection housing is formed of two half shells fastened together by means of a butt joint to hold down the guide tube therein for the connection of the mating female or male connector.
However, the two half shells of the connection housing can easily get loosened, affecting connection between the mating male and female connectors. Some other prior art designs employ a socket joint connection method to achieve connection between the connection housing and the guide tube, eliminating the connection instability problem of the aforesaid butt joint. However, this socket joint connection method cannot lock the connection housing and the guide tube in position. The connection housing and the guide tube can be displaced relative to each other. An improvement in this regard is desired.

It is one object of the present invention to provide a connector module, which uses claws for engagement with an endless groove around the periphery of a guide tube to secure lead wire holder assembly to a connection housing tightly, facilitating the assembly process.
To achieve this and other objects of the present invention, a connector module comprises a connection housing, a lead wire holder assembly, and a male connector. The connection housing comprises a through slot axially cut through opposing front and rear sides thereof, an adapter portion located at the rear side around the through slot, a plurality of claws spaced around an inside wall of the adapter portion and respectively defined with the inside wall of the adapter portion a predetermined contained angle, and a retaining groove located on the inside wall of the adapter portion. The lead wire holder assembly is inserted into the through slot of the connection housing, comprising a holder shell and a lead wire module inserted into the holder shell. The holder shell comprises a guide tube. The guide tube comprises an endless groove extended around the periphery thereof and forced into engagement with the claws of the connection housing, and a locating block located thereon adjacent to the endless groove and positioned in the retaining groove of the connection housing. The lead wire module comprises a locating seat inserted into the guide tube. The locating seat comprises a plurality of longitudinally extended through slots adapted for holding respective lead wires, a wrapping block comprising a locating plate, two cover plates respectively hinged to two opposite sidewalls of the locating plate and respectively defining therein a plurality of wire grooves for accommodating respective lead wires and two hook lugs respectively extended from respective free ends of the cover plates and adapted for hooking on the locating plate to secure the respective cover plates to the locating plate in a closed position. The male connector is connectable with the adapter portion of the connection housing, comprising a front housing defining a connection hole in a front end thereof for receiving the connection housing, a rear housing connected to an opposing rear side of the front housing for guiding the extending direction of lead wires and a lead wire tube mounted in the front housing and the rear housing and holding a plurality of lead wires therein for conduction with the respective lead wires in the adapter portion of the connection housing.
