ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cable connector assembly, and particularly to a cable connector assembly for transmission of signals among a keyboard/mouse, a keyboard/mouse interface in a host computer, and an interface of a network server, and a method for manufacturing the cable connector assembly.
2. Description of Prior Art
A conventional cable connector assembly used in the computer industry is shown in FIG.

, a collected plug
6
to be connected to a network server, and four cables

each having a plurality of wires therein and extending from a rear end of each single plug
5
to the collected plug
6
. The single plugs

a
to be connected to a keyboard, a male MINI DIN type plug

to be connected to a keyboard interface in a host computer, a female MINI DIN type plug
52
a
to be connected to a mouse, and a male MINI DIN type plug
52
b
to be connected to a mouse interface in the host computer. To transmit signals among the keyboard, the mouse, the keyboard and mouse interfaces in the host computer, and the network server, the prior art cable connector assembly needs nine components, i.e., four single plugs
5
, four cables
7
and a collected plugs
6
, which requires a complicated and high cost inventory. Furthermore, for transmitting signals between the female MINI DIN plugs
51

52
a
and corresponding male MINI DIN plugs
51
b
,
52
b
, the wires of the cables
7
a
and
7
b
respectively need to be electrically connected to the wires of the cable
7
c
and

within the collected plug

, thus causing the manufacture of the assembly to be complicated. Hence, an improved electrical connector is required to overcome the disadvantages of the prior art.
SUMMARY OF THE INVENTION
A first object of the present invention is to provide a cable connector assembly which has plugs with female and male contact units which are fixed together and can easily transmit signals therebetween.
A second object of the present invention is to provide a cable connector assembly which has a reduced number of components thereby decreasing manufacturing cost and space requirements.
A further object of the present invention is to provide a method for manufacturing the cable connector assembly.
A cable connector assembly in accordance with the present invention comprises two plugs, a collected plug and two cables each extending from a different plug to the collected plug. To perform a function similar to that of the prior art, the present invention needs only five components thus the manufacturing cost is decreased. Each plug includes a first contact unit and a second contact unit, a joint connecting the first and second contact units, and a jacket covering the first and second contact units. A first end of each cable extends into the corresponding plug at a position between the first and second contact units and is fixed by a fixing portion integrally formed with the jacket. The first end of each cable extends through an aperture of the fixing portion at a specified angle. The collected plug connects with second ends of the cables and is connected to an interface of a network server. A method for manufacturing the cable connector assembly comprises the steps of: (A) preparing the first and second contact units; (B) a soldering step; (C) forming the joint; (D) forming the jacket; (E) forming the jacket of the collected plug.
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.
