ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a cable connector having a system for high-speed signal transmission, and particularly to a new assembly of the grounding plate and insulative spacer of the system for high-speed signal transmission.
Taiwan Patent Application Nos. 86102087; 86102088; 86102094 and 86102095 disclose cable connectors with a system for high-speed signal transmission. U.S. Pat. No. 5,768,771 as shown in
FIG. 5
, discloses a conventional high speed cable connector
90
which has a dielectric housing
91
, two terminal blocks
93
, a plurality of high speed signal terminals
94
inserted molded with the terminal blocks
93
, a grounding plate
95
clamped between the terminal blocks
93
, and a plurality of coaxial cables
96
. The grounding plate
95
forms a plurality of wing-shaped position arms
952
at a rear end thereof. Each cable
96
has a center conductor
962
and a metallic braid
964
. The center conductor
962
is soldered to an end of a corresponding terminal
94
. The position arms
952
clamp the metallic braids
964
of each of the coaxial cables
96
, thereby retaining the cable and transmitting electrostatic charge to ground via a mating connector (not shown) engaged with the cable connector
90
. However, to manufacture a conventional high-speed cable connector by insert molding the terminals with the terminal block, all the terminals are first positioned in the molds, and then molten plastic is inserted into the molds under high pressure. Using this procedure, it is difficult to achieve a product with the terminals in the preferred position since the terminals are very thin, so production output suffers. 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 system for high-speed signal transmission that is easy to manufacture and easy to assemble into the connector.
A cable connector having a system for high-speed signal transmission of the present invention comprises an insulative housing, a plurality of data transmission terminals received in one side of the insulative housing, and a system for high-speed signal transmission received in an opposite side of the insulative housing.
The system for high-speed signal transmission comprises a plurality of high-speed signal terminals, a grounding plate, an insulative spacer, and a ferrule. The insulative spacer has a front face and a rear face and defines an elongate slot extending therethrough, a pair of grooves being defined in the front face and in communication with the slot, a plurality of passageways being defined on opposite sides of the slot for receiving the signal terminals. The elongate grounding plate defines a pair of teeth laterally projecting from opposite side edges thereof, the grounding plate extending through the slot of the insulative spacer and the teeth fitting into the grooves of the insulative spacer. The ferrule clamps a plurality of metallic braids each corresponding to a coaxial cable connected to the high-speed signal terminal to the grounding plate.
