Abstract

An electrical connector assembly (100) in accordance with the present invention, comprises a receptacle connector (20) and plug connector (10). The receptacle connector comprises an insulative housing (21) and a plurality of first terminals (24) received in the housing. The housing comprises a base portion (211) and a mating portion (212) extending from the base portion (211). The mating portion (212) comprises a top wall, a bottom wall and a pair of side walls connecting with the top and the bottom walls and defines a tongue (26) therein. A lateral side of tongue connects with one of the side walls, and another side of the tongue is spaced with the other side wall where a recess (262) is formed. The plug connector comprises an insulative housing (11) and a plurality of second terminals (14) received in the insulative housing. The housing comprises a base portion (111) and a pair of parallel tongues (113) extending from the base portion. A rib (114) is formed to connects the two tongues. The rib is received in the recess when the two connectors engaged with each other to avoid mis-mating.

Claims

1. An electrical connector assembly comprising:

a first connector comprising an insulative housing and a plurality of first terminals received in the insulative housing, the insulative housing comprising a base portion and a mating portion extending from the base portion, the mating portion comprising a top wall, a bottom wall, a pair of side walls and a tongue extending between the side walls and parallel to the top and the bottom walls, the housing defining a recess between a lateral side of the tongue and one of the two side walls; and

a second connector comprising an insulative housing and a plurality of second terminals received in the insulative housing, the insulative housing comprising a base portion and a pair of parallel tongues extending from the base portion, the housing defining a rib connecting the pair of tongues;

wherein the rib of the second connector is received in the recess of the first connector when the two connectors engage with each other.

2. The electrical connector assembly as described in claim 1, wherein the shell of the first connector comprises a first shell and a second shell, the first shell encloses the mating portion of the insulative housing, the second shell encloses the base portion of the insulative housing.

3. The electrical connector assembly as described in claim 1, wherein the second connector comprises a third shell, the third shell encloses the base portion of the second connector.

4. The electrical connector assembly as described in claim 1, wherein the base portion of the first connector comprises a plurality of passageways extending therethrough and arranged in four rows, a bottom face of the upper face, a top face of the lower wall of the mating portion of the first connector and two opposite faces of the tongue, respectively, defining a plurality of receiving slots communicating with the corresponding passageways.

5. The electrical connector assembly as described in claim 4, wherein each first terminal comprises a contacting portion, an intermediate portion extending from the contacting portion and a soldering portion extending downwardly from the intermediate portion.

6. The electrical connector assembly as described in claim 5, wherein the intermediate portion of the first terminal is received in the passageways of the first connector and the contacting portion extending into the receiving slots of the first connector, the soldering portion extending beyond the insulative housing of the first connector.

7. The electrical connector assembly as described in claim 6, wherein the first connector comprises a spacer assembled on the rear thereof, and wherein the spacer comprises a base, a ladder portion extending from the base and a pair of projections extending oppositely from opposite ends of the base, the base defines a plurality of holes extending therethrough, and the ladder portion defines a plurality of positioning slits on the back thereof.

8. The electrical connector assembly as described in claim 1, wherein each second terminal comprises a contacting portion, a intermediate portion extending from the contacting portion and a soldering portion extending from the intermediate portion.

9. The electrical connector assembly as described in claim 8, wherein the base portion of the plug connector defines a plurality of passageways extending therethrough, and wherein top and bottom faces of each tongue define a plurality of receiving slots thereon communicating with corresponding passageways, the intermediate portion of the second terminal being received in the passageways, and the contacting portion extending into the receiving slot.

10. An electrical connector assembly comprising:

a first connector comprising an insulative housing and a plurality of first terminals received in the insulative housing, the insulative housing comprising a base portion and a mating portion extending from the base portion, the mating portion being of a lying U-shaped configuration and enclosed in a first outer shell; and

a second connector comprising an insulative housing and a plurality of second terminals received in the insulative housing, the insulative housing comprising a base portion and a mating section extending from the base portion and enclosed in the second shell, said mating section defining therein a lying U-shaped recess therein;

wherein

when the first and second connectors are mated with each other, the lying U-shaped configuration is received in the lying U-shaped under a condition that the second shell is enclosed in the first shell.

11. The electrical connector assembly as described in claim 10, wherein the first and second terminals are mated in four rows.
