Abstract

An electrical connector (1) adapted to mate with a complementary connector (90) which has a tongue portion (91) with a plurality of conductive terminals (92) disposed thereon, includes an insulative housing (50) having a mating portion (53) protruding forwardly therefrom and a receiving cavity (55) defined therethrough, and a plurality of conductive contacts (60) received in the cavity of the housing. An upper wall (531) and a lower wall (532) form the mating portion, with the receiving cavity being defined therebetween. The contacts are positioned on the lower wall. A pair of engaging bars (551) protrudes from the upper wall into the receiving cavity. When the mating portion mates with the tongue portion, the engaging bars downwardly push the tongue portion to ensure a reliable connection between the conductive terminals and corresponding contacts.

Claims

1. An electrical connector adapted to mate with a complementary connector which has a tongue portion with conductive terminals disposed thereon, comprising:

an insulative housing having opposing first and second walls with a receiving cavity defined therebetween;

a plurality of conductive contacts received in the receiving cavity of the housing and positioned on the first wall; and

an engaging bar protruding from the second wall into the receiving cavity for pushing against the tongue portion of the complementary connector to ensure reliable engagement between the conductive terminals of the tongue portion and corresponding contacts on the first wall upon insertion of the tongue portion of the complementary connector into the receiving cavity;

wherein

the engaging bar is formed on a rear portion of the second wall and extends in a rear-to-front direction;

wherein

the engaging bar comprises an inclined surface at a front end thereof, further comprising a metallic shield having an upper shield and a lower shield for shielding the housing and the contacts, the upper shield having at one end an upper panel and a lower panel opposite to said upper panel.

2. The electrical connector as claimed in claim 1, further comprising a cover receiving the metallic shield, the housing and the contacts therein, and wherein the first and second walls of the housing and the shield partially extend out of the cover.

3. An electrical connector assembly, comprising:

a plug connector having a first mating portion and a plurality of first contacts positioned on the first mating portion; and

a receptacle connector having a second mating portion for mating with the first mating portion and a plurality of second contacts positioned on the second mating portion;

wherein

one of the first and second mating portions comprises an inner engaging bar, and when the plug connector mates with the receptacle connector, the engaging bar urges the other of the first and second mating portions to engage with said one of the first and second mating portions, and makes the first and second contacts reliably connect with each other;

wherein

the engaging bar is formed on a rear portion of said one of the first and second mating portions, and extends in a rear-to-front direction;

wherein

the engaging bar comprises an inclined surface at a front end thereof;

wherein

the plug connector comprises a receiving cavity, and the receptacle connector comprises a tongue portion formed as the second mating portion to be inserted into the receiving cavity of the plug connector,

further comprising a metallic shield having an upper shield and a lower shield for shielding a housing of the plug connector and the first contacts, the upper shield having at one end an upper panel and a lower panel opposite to said upper panel.

4. The electrical connector assembly as claimed in claim 3, wherein the plug connector has upper and lower walls on opposite sides of the receiving cavity, and the tongue portion of the receptacle connector comprises upper and lower surfaces, and wherein the first contacts are positioned on the lower wall, and the second contacts are positioned on the lower surface.

5. The electrical connector assembly as claimed in claim 4, wherein the engaging bar is formed on one of the upper wall of the plug connector and the upper surface of the tongue portion of the receptacle connector.
