ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a cable connector, and especially to a cable connector for terminating multiple conductive wires.
Cable connectors are common components in electronic systems. A conventional cable connector is disclosed in Taiwan Patent Application No. 78110089. Such connectors generally comprise contacts having piercing structures which pierce through insulated conductive wires thereby electrically connecting with conductors thereof for communicating signals. Insulative housings of conventional cable connectors usually adopt a riveting process to connect with corresponding shells. However, since the riveting process requires additional riveting tools, manufacture and assembly of the cable connectors is complicated.
Thus, an improved prior cable connector having an insulative housing and a shell combined together by a latching is provided. Referring to
FIG. 1
, in which an upper securing member is omitted for the sake of clarity, a conventional cable connector
8
includes an insulative housing
80
, a shell
82
, a plurality of contacts
84
, an upper securing member and a lower securing member
86
. The housing
80
has a base plate
800
defining cutouts
802
in an upper surface and a lower surface. The shell
82
forms a plane surface
820
engaged to a side of the base plate
800
of the housing
80
. A pair of mounting ears
822
extend proximate opposite ends of the plane surface
820
for engaging the cutouts
802
of the housing
80
whereby the housing
80
is assembled to the shell
82
. However, the positioning members
822
are bent spring clips susceptible to resilient deformation. Thus, a sufficient latching force may be difficult to provide in the mating direction of the cable connector
8
and a mating connector, thereby causing the shell
82
to become disconnected from the housing
80
.
BRIEF SUMMARY OF THE INVENTION
A main object of the present invention is to provide a cable connector comprising at least an insulative housing firmly latched with a D-shaped shell having a pair of positioning members for assembling the shell with the housing and integrally combining the shell with the other components of the cable connector.
In accordance with one aspect of the present invention, a cable connector comprises a front insulative housing, a rear insulative housing, a shell, a plurality of contacts and a pair of positioning members. The front insulative housing includes a base board and a mating section projecting from the base board. The mating section defines an upper row of engaging slots and a lower row of engaging slots through the base board. The rear insulative housing is assembled to the front housing from the base board, and forms a joining section for being assembled with the base board of the front housing and a main body extending rearwardly from the joining section. The main body comprises a receiving section and two joining sections extending from opposite ends of the main body. The receiving section forms a plurality of receiving slots corresponding to the engaging slots of the front housing thereby forming a plurality of common receiving slots for receiving corresponding contacts. Each contact comprises a piercing section and a joining section. The shell forms a base plate and is assembled to the housing from one side of the mating section of the front housing. A shielding section forwardly protrudes from a middle portion of the base plate. A pair of latching arms rearwardly extend from opposite ends of the base plate for being partially received in the chamber of the rear housing and engaging with the positioning members positioned in the positioning holes of the rear housing.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
