Abstract

An electrical connector assembly (100) includes a top shell (11), a bottom shell (12) forming a bottom plate (32) defining a receiving room with the top shell, a connector module (51), a printed circuit board (PCB) (52) electrically connecting with the connector module, a pair of mating screws (43) and a pair of spring members (430). The top shell forms a cutout (110) exposed along a vertical direction. The connector module is located vertically in the receiving room and extends through the cutout. The PCB includes a pair of limiting holes (521) and the mating screws have threads and screw caps. The threads pass through the bottom plate and the corresponding limiting holes to lock with the top shell. The pair of spring members is supported by the mating screws, and compressed between a bottom surface of the PCB and a top surface of the screw caps.

Claims

1. An electrical connector assembly, comprising:

a top shell having a cutout exposed along a vertical direction;

a bottom shell, shaped in a bowl, comprising a bottom plate and defining a receiving room with the top shell;

a connector module located vertically in the receiving room and extending through the cutout;

a printed circuit board (PCB), electrically connecting with the connector module and comprising a pair of limiting holes;

a pair of mating screws having threads and screw caps, the threads passing through the bottom plate and the corresponding limiting holes to lock with the top shell; and

a pair of spring members supported by the mating screws and compressed between a bottom surface of the PCB and a top surface of the screw caps.

2. The electrical connector assembly as described in claim 1, further comprising a second PCB and a second connector module soldered with the second PCB both located in the receiving room, and wherein the two PCBs electrically connect with each other by cable wires.

3. The electrical connector assembly as described in claim 2, wherein the second connector module is located horizontally.

4. The electrical connector assembly as described in claim 3, further comprising a second cutout formed on the bottom shell with a mouth exposed along a horizontal direction and wherein the second connector module partly extends through the second cutout.

5. The electrical connector assembly as described in claim 4, wherein the top shell forms a pair of mating bolts receiving the threads of the mating screws, and the screw caps of the mating screws are limited by but not fixed onto the bottom plate.

6. The electrical connector assembly as described in claim 5, further comprising a plurality of fixing screws having threads and screw caps.

7. The electrical connector assembly as described in claim 6, wherein the top shell forms a plurality of fixing bolts receiving the threads of the fixing screws, and the screw caps of the fixing screws are locked with the bottom plate.

8. The electrical connector assembly as described in claim 4, further comprising a fixing board located between the top shell and the bottom shell.

9. The electrical connector assembly as described in claim 8, wherein the fixing board forms a pair of mating bolts receiving the threads of the mating screws, and the screw caps of the mating screws are limited by but not fixed onto the bottom plate.

10. The electrical connector assembly as described in claim 9, wherein the fixing board forms a plurality of fixing bolts, a plurality of fixing screws pass through the bottom plate and are received in corresponding fixing bolts.

11. The electrical connector assembly as described in claim 10, wherein the fixing board forms an opening and the bottom shell forms a protruding portion received in the opening.

12. The electrical connector assembly as described in claim 1, wherein the top shell forms a plurality of hooks, and the bottom shell forms a plurality of slots locked with the hooks.

13. The electrical connector assembly as described in claim 1, wherein a base with a depressed portion is located between the PCB and the springs.

14. The electrical connector assembly as described in claim 13, wherein the limiting holes comprise first limiting holes, and the base comprises a pair of second limiting holes overlapped with the first limiting holes along the vertical direction.

15. The electrical connector assembly as described in claim 1, wherein the bottom plate is separately attached to the bottom shell.

16. The electrical connector assembly as described in claim 1, further comprising a metal frame received in the bottom shell.

17. The electrical connector assembly as described in claim 1, further comprising a bottom board made of rubber material.

18. An electrical connector assembly comprising:

a casing comprising a top shell and a bottom shell with a receiving room defined therein, the top shell defining a top face and the bottom shell defining a circular wall;

a connector essentially disposed in the receiving room of the casing with a mating port exposed on said top face, said connector including a plurality of contacts; and

a printed circuit board on which the connector is seated and to which the contacts are electrically connected;

wherein

the printed circuit board and the associated connector are allowed to be downwardly moved under a cushiony manner via a biasing member.

19. The electrical connector assembly as claimed in claim 18, further including another connector disposed in the receiving room of the casing with another mating port exposed on said lateral wall, and wherein said another connector has a plurality of terminals electrically connected to another printed circuit board and wherein said two printed circuit boards connect with each other via internal cables.

20. The electrical connector assembly as claimed in claim 19, wherein said another connector is positioned with regard to the casing in a stationary manner.
