1. Field of the Invention
This application claims priority to prior Chinese patent applications 200810305432.8 and 200820302697.8, the disclosure of which are incorporated herein by reference.
The present invention generally relates to a cable connector assembly, and more particularly to a cable connector assembly with an improved cover.
2. Description of Related Art
A conventional, cable connector assemblies are widely used in an electronic equipment, especially for transmitting power, and the performance of the cable connector assembly directly impacts on the entire electronic equipment whether can normally run.
U.S. Pub. No. 2006/0110978A1 published to Fan on Aug. 1, 2005 discloses a cable connector assembly, the cable connector assembly is a power connector and comprises a plurality of insulative housings, and each insulative housing has a contact received therein. Each insulative housing defines a slot and a projection located on both sides thereof, and the slot of one insulative housing is engaging with the projection of another insulative housing to make the two neighboring insulative housings conjunct with each other. However, the combination between the two insulative housings may be weak to induce the two contacts to be located on different planes, and an electrical connection between the cable connector assembly and a complementary connector may be unstable.
Correspondingly, it is desired to have a cable connector assembly with an unitary connector molded with another connector to address the problems stated above.
Accordingly, an object of the present invention is to provide a cable connector assembly having a unitary connector molded with another connector.
In order to achieve the above-mentioned object, a cable connector assembly in accordance with the present invention comprises an electrical connector, a cable connected with the electrical connector and an insulated cover over-molded on an electrical connection between the electrical connector and the cable. The electrical connector includes a first connector and a second connector, each of the first connector and the second connector have a contact, a middle tube enclosing the contact and an outer tube enclosing the middle tube. A first insulated housing is defined between the outer tube and the middle tube of the first connector, and a second insulated housing is defined between the outer tube and the middle tube of the second connector, the first insulated housing is unitarily molded with the second insulated housing. The insulated cover comprises a pair of receiving channels.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawing figures to describe the present invention in detail.

Referring to
The middle tubes 30, 40 are made of conductive material, and named as the first middle tube 30 and the second middle tube 40. The second middle tube 40 has a larger front segment and a smaller back segment to form a step portion therebetween.
The outer tubes 50, 60 are also made of conductive material, and extend backwards to form arc-shaped joining portions 501, 601 receiving solder. The first and second middle tubes 30, 40 are enclosing the signal contact 10 and the power contact 20 respectively, the outer tubes 50, 60 are enclosing and spaced from the first and the second middle tubes 30, 40, the insulated housing 70 is filled in a spaced area between the outer tube 50 and the first middle tube 30, and the insulated housing 80 is filled in a spaced area between the outer tube 60 and the second middle tube 40. The insulated housings 70, 80 are unitarily molded with each other, and connected with each other by a linking portion 71. A tab 801 is defined in a cavity of the insulated housing 80 to prevent the contacting portions 102, 202 from mismating with a complementary connector (not shown).
Referring to
The cable 91 comprises a pair of wires 51, 52 connected with the first connector 1 and the second connector 2 respectively, and each wire comprises three conductors (not shown) electrically connecting with the contact 10, 20, the middle tube 30, 40 and the outer tube 50, 60.
The insulative cover 92 is over-molded on the electrical connection between the electrical connector 100 and the cable 91. The insulative cover 92 defines a first receiving channel 921 and a second receiving channel 922 recessed from front to back, the first connector 1 and the second connector 2 are enclosed in the first receiving channel 921 and the second receiving channel 922. A circular pressing portion 923 is recessed downwards from a bottom surface of the insulative cover 92, an indentation 924 is defined in a front end of the insulative cover 92 and recessed downwards from the bottom surface of the insulative cover 92, to prevent the cable connector assembly 200 from mismating with the complementary connector. The indentation 924 is located in front of the pressing portion 923.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
