ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a cable connector, and particularly to a cable connector having improved terminals fitting into a smaller space for data transmission.
U.S. Pat. No. 5,722,861 discloses a cable connector with data transmission terminals. Because a retaining space for receiving the data transmission terminals in the housing is limited, the terminals often insert molded in an insulative block thereby saving the retaining space of the housing. U.S. Pat. No. 5,722,861 discloses a cable connector
200
as shown in
FIG. 5
which has an insulative housing
80
and a plurality of terminal modules
90
received in the housing
80
. The terminal modules
90
are made by insert molding terminals
94
within the insulative blocks
92
thereby allowing more terminals
94
to be received in a limited space. However, manufacturing a conventional cable connector by insert molding the terminals within insulative blocks may waste time and increase production cost. Hence, an improved cable connector having a system for high-speed signal transmission is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide a cable connector having a plurality of improved terminals fitting into a smaller space for positioning in the limited space of an insulative housing.
A cable connector comprises an insulative housing, a plurality of data transmission terminals received in one side of the insulative housing, a system for high-speed signal transmission received in an opposite side of the insulative housing, and a shield covering the housing.
The housing has a mating surface and a mounting surface opposite to the mating surface. The housing defines one or more rows of receiving holes extending through the mating surface and the mounting surface for receiving the data transmission terminals. A cross-section of the receiving holepresents a slanted rectangle section plus a pair of recessing sections on opposite long sides of the slanted rectangle section. Each recessing section defines a vertical peripheral wall. The data transmission terminal comprises a gradually twisted contact portion at one end thereof, a straight extending portion connected with the contact portion, and a securing portion at the other end thereof correspondingly twisted in a similar direction as the contact portion. The straight extending portion has a width comparable to a horizontal distance between the peripheral walls of the recessing sections of the receiving hole. The securing portion is securely received in the slanted rectangle section of the housing thereby saving the lateral space of the housing.
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.
