Abstract

A plug connector assembly for mating with a complementary connector includes a printed circuit board (PCB) defining a plurality of conductive pads, a pair of metal members mounted on two sides of the PCB and soldered with the PCB for electrically connecting with the complementary connector, an inserting member electrically connected on a front end of the PCB to connect to the complementary connector, and a housing enclosing the PCB. The PCB includes a front portion, an opposite rear portion, and a middle portion connecting the front portion and the rear portion. The conductive pads include a plurality of first pads disposed on the front portion. The inserting member includes an insulative member and a plurality of terminals held on the insulative member. The terminals are soldered with corresponding first pads.

Claims

1. A plug connector assembly for mating with a complementary connector, comprising:

a printed circuit board (PCB) defining a plurality of conductive pads, the PCB comprising a front portion, an opposite rear portion, and a middle portion connecting the front portion and the rear portion, the conductive pads comprising a plurality of first pads disposed on the front portion;

a pair of metal members soldered to two sides of the PCB for electrically connecting with a complementary connector;

an inserting member electrically connected on a front end of the PCB for connecting to the complementary connector, the inserting member comprising an insulative member and a plurality of terminals held on the insulative member, the terminals soldered with corresponding first pads; and

a housing enclosing the PCB;

wherein the insulative member comprises a head portion defining a top wall and a pair of first arms extending from two sides of the head portion, each terminal comprising a contacting portion exposed out of the top wall of the head portion for electrically contacting with the complementary connector and a connecting portion extending beyond the top wall and disposed between the pair of the first arms for soldering with the first pads.

2. The plug connector assembly as recited in claim 1, wherein the conductive pads comprise a plurality of second pads disposed on the middle portion of the PCB, and the metal member comprises a latching portion for latching with the complementary connector, a second arm extending from the latching portion, and a soldering portion disposed at the end of the second arm and soldered with the second pads.

3. The plug connector assembly as recited in claim 1, wherein the PCB comprises an upper surface and an opposite lower surface each comprising the first pads, and there are a pair of inserting members enclosing the PCB, one inserting member mounted on the upper surface and soldered with the first pads on the upper surface, and the other inserting member mounted on the lower surface and soldered with the first pads on the lower surface.

4. The plug connector assembly as recited in claim 3, wherein each inserting member comprises a stop wall in a transverse direction, a receiving slot formed between the stop wall and a horizontal surface, and the housing comprises an upper housing part and a lower housing part, each housing part comprising a main portion and a tongue portion extending from the main portion, the tongue portion comprising a receiving portion inserted into the receiving slot to prevent the front end of the housing from perking.

5. The plug connector assembly as recited in claim 4, wherein the conductive pads further comprise a plurality of third pads disposed on the middle portion of the PCB, and the tongue portion of the housing comprises a spring tab proximal to the main portion of the housing and bending inwardly to solder with the third pads.

6. A method for manufacturing a plug connector assembly, comprising the steps of:

providing a printed circuit board (PCB) defining a plurality of conductive pads;

mounting a pair of metal members on two sides of the PCB;

mounting a pair of inserting members on the PCB, each inserting member comprising an insulative member and a plurality of terminals held on the insulative member, the insulative member comprising a head portion and a pair of first arms extending from two sides of the head portion, each inserting member comprising a receiving slot, the terminals soldered with the corresponding conductive pads, the first arms mechanically mating with the PCB;

assembling a housing to enclose the PCB; and

molding a cover to the housing;

wherein

each metal member comprises a latching portion for latching with the complementary connector, a second arm extending from the latching portion, and a soldering portion disposed on the end of the second arm and soldered with the conductive pads to fix the metal member on the PCB.

7. The method as recited in claim 6, wherein the step of assembling comprises inserting a front end of the housing into the receiving slot of the inserting member to prevent the front end from perking.

8. The method as recited in claim 6, wherein the housing comprises an upper housing part and an opposite lower housing part, the upper housing part soldered with the lower housing part after assembling to increase the anti-bending strength of the plug connector assembly.

9. An electrical connector comprising:

a pair of inserting members stacked together with a plate sandwiched therebetween around corresponding rear portions of said pair of inserting members in a vertical direction, each of said inserting member including an insulative member with a plurality of contacts embedded therewith via an insert molding process;

wherein

front contacting sections of the contacts are exposed to an exterior in the vertical direction;

a pair of metallic shells enclosing the plate and rear portions of the inserting members; and

a metal member surrounding a periphery of the pair of inserting members with a pair of locking recesses on two lateral sides for locking with a corresponding latch of a complementary connector;

wherein

the insulative member forms a recess in which a front end of the corresponding shell is received so as to prevent the shell from being withdrawal from the insulative member in said vertical direction;

wherein

the plate is a printed circuit board on which the contacts are soldered.
