Abstract

An electrical connector is adapted to connect two signal transmission cables, and includes a terminal seat with a plurality of insert slots for snugly gripping transmission wires of one transmission cable. The terminal seat has two lateral portions and a transverse portion extending therebetween such that the distances of the adjacent insert slots can be increased so as to increase the distance between the transmission wires respectively mounted in the insert slot, thereby reducing the electromagnetic coupling effect therebetween.

Claims

1. An electrical connector adapted to connect first and second signal transmission cables, each including a plurality of electrically insulated transmission wires, the first transmission cable being provided with a wire terminal plug that terminates the transmission wires thereof, said electrical connector comprising:

a base seat;

a socket member mounted on said base seat and adapted for insertion of the wire terminal plug in a longitudinal direction;

a circuit board mounted on said base seat, and having front and rear segments opposite to each other in the longitudinal direction and electrically connected to each other;

a plurality of first terminals which are mounted on and electrically connected to said front segment, which are received in said connecting socket, and which are adapted to respectively and electrically connect with the transmission wires of the first signal transmission cable when the wire terminal plug is inserted into said socket member;

a terminal seat mounted on said rear segment of said circuit board, and including two lateral portions which are spaced apart from each other in a transverse direction relative to the longitudinal direction and which extend forwardly in the longitudinal direction to form respectively front ends, and a transverse portion which extends in the transverse direction between said front ends of said lateral portions, each of said lateral and transverse portions extending from said circuit board upwardly in an upright direction transverse to the longitudinal and transverse directions to terminate at an upper wall surface, said upper wall surface of each of said lateral and transverse portions being formed with a plurality of insert slots which are displaced from one another, each of said insert slots extending downwardly to be adapted to snugly grip a respective one of the transmission wires of the second signal transmission cable by press fitting; and

a plurality of second terminals respectively mounted in said insert slots, and electrically connected to said second segment of said circuit board so as to respectively establish electrical connection with the transmission wires of the second signal transmission cable when the transmission wires are press-fitted respectively into said insert slots.

2. The electrical connector of claim 1, wherein said transverse portion extends to interconnect and is formed integrally with said front ends of said lateral portions.

3. The electrical connector of claim 2, wherein said terminal seat has a recessed opening facing rearwards and adapted to serve as an access for introducing thereinto the transmission wires of the second signal transmission cable in the longitudinal direction, an inner wall surface extending from one of said lateral portions through said transverse portion to the other one of said lateral portions so as to confine said recessed opening, and an outer wall surface disposed outboard to said inner wall surface, each of said insert slots extending from said inner wall surface through said outer wall surface.

4. The electrical connector of claim 3 adapted to connect two sets of twisted-pairs of the electrically insulated transmission wires respectively sheathed in the first and second signal transmission cables, wherein said terminal seat has a plurality of pairs of said insert slots, each pair of said insert slots being disposed adjacent to each other to be adapted to snugly grip a respective pair of the transmission wires of the second signal transmission cable, and extending to diverge from each other from said inner wall surface to said outer wall surface.

5. The electrical connector of claim 4, wherein each pair of said insert slots define an angle of 45 degrees therebetween.

6. The electrical connector of claim 4, wherein said terminal seat has a cross-section in a horseshoe shape.

7. The electrical connector of claim 5, further comprising a shielding member configured such that when said shielding member is brought downward and in the upright direction, said shielding member is disposed outboard to said outer wall surface, thereby shielding said insert slots.
