Abstract

An electrical plug connector includes an insulated housing and a rear positioning block. The rear positioning block is assembled to the rear of the insulated housing. The rear positioning block includes a base and a gluing passage. The front of the base corresponds to the rear of the insulated housing. The width of the base is greater than the width of the insulated housing. The periphery of the base is protruded from the periphery of the insulated housing. The gluing passage is formed at a peripheral area of the base, and the gluing passage is defined through the base from the front to the rear.

Claims

1. An electrical plug connector, comprising:

a metallic shell, defining a receiving cavity therein;

an insulated housing, received in the receiving cavity, the insulated housing comprising an upper portion, a lower portion, and a mating room, wherein the mating room is defined at the front of the insulated housing and between the upper portion and the lower portion, the upper portion has an upper mating face, the lower portion has a lower mating face, the upper mating face is faced toward the lower mating face;

a plurality of upper-row plug terminals, held in the insulated housing and located upon the upper mating face of the upper portion, wherein the upper-row plug terminals comprise a plurality of pairs of upper signal pairs for signal transmission, at least one power terminal, and at least one ground terminal;

a plurality of lower-row plug terminals, held in the insulated housing and located upon the lower mating face of the lower portion, wherein the lower-row plug terminals comprise a plurality of pairs of lower signal pairs for signal transmission, at least one power terminal, and at least one ground terminal; and

a rear positioning block, assembled to a rear of the insulated housing, the rear positioning block comprising;

a base, wherein the front of the base corresponds to the rear of the insulated housing, the width of the base is greater than the width of the insulated housing, and the cross sectional area of the base is greater than the cross sectional area of the insulated housing; and

a gluing passage formed at a sidewall of the base, wherein the gluing passage is defined through the base from the front of the base to the rear of the base.

2. The electrical plug connector according to claim 1, wherein the gluing passage defines a groove structure located at a side of the top surface of the base or a side of the bottom surface of the base.

3. The electrical plug connector according to claim 1, wherein the gluing passage is formed at a right sidewall or a left sidewall of the base.

4. The electrical plug connector according to claim 1, wherein the gluing passage defines a through-hole structure and the through-hole structure is defined through the base.

5. The electrical plug connector according to claim 1, wherein the rear positioning block comprises a plurality of buckling blocks respectively formed at the top and the bottom of the base, and wherein the metallic shell comprises a plurality of buckling rings, each of the buckling rings is buckled with the corresponding buckling block.

6. The electrical plug connector according to claim 1, further comprising a covering member extended from the rear of base, through the gluing passage, and toward the rear of the metallic shell.

7. The electrical plug connector according to claim 1, further comprising a circuit board assembled to the rear of the rear positioning block, wherein the circuit board comprises a plurality of ground contacts connected to rear of the upper-row plug terminals and rear of the lower-row plug terminals.

8. The electrical plug connector according to claim 1, wherein each of the upper-row plug terminals comprises a flexible contact portion, a body portion, and a tail portion, wherein the body portion is held in the upper portion, the flexible contact portion is extended forward from the body portion in the rear-to-front direction and partly exposed upon the upper mating face of the upper portion, and the tail portion is extended backward from the body portion in the front-to-rear direction and protruded from the insulated housing.

9. The electrical plug connector according to claim 1, wherein each of the lower-row plug terminals comprises a flexible contact portion, a body portion, and a tail portion, wherein the body portion is held in the lower portion, the flexible contact portion is extended forward from the body portion in the rear-to-front direction and partly exposed upon the lower mating face of the lower portion, and the tail portion is extended backward from the body portion in the front-to-rear direction and protruded from the insulated housing.

10. The electrical plug connector according to claim 1, wherein the upper-row plug terminals and the lower-row plug terminals have 180 degree symmetrical design with respect to a central point of the receiving cavity as the symmetrical center.

11. The electrical plug connector according to claim 10, wherein the position of the upper-row plug terminals correspond to the position of the lower-row plug terminals.
