Abstract

An electrical connector assembly is adapted for electrical connecting and retained on a wireless module with a receptacle RF connector mounted on an end of the wireless module is provided. The assembly includes a coaxial cable connector including a connector end and a coaxial cable extending from the connector end and a retention member including a main base and a retention cavity in front of the main base, the main base defining a corresponding cable receiving groove through a front end and a rear end of the main base. The retention cavity further defines a projecting portion elastically pressing against a surface of the end of the wireless module when the end of the wireless module, the receptacle RF connector and the connector end of the coaxial cable connector are receiving in the retention cavity and the coaxial cable go through the cable receiving groove.

First claim

What is claimed is:

1. An electrical connector assembly adapted for electrical connecting and retained on a wireless module with a receptacle RF (Radio Frequency) connector mounted on an end of the wireless module, comprising:
a coaxial cable connector comprising a connector end intending to mate with the receptacle RF connector and a coaxial cable extending from the connector end; and
a retention member comprising a main base and a retention cavity in front of the main base, the main base defining a corresponding cable receiving groove through a front end and a rear end of the main base;
wherein the retention cavity further defines a projecting portion elastically pressing against a surface of the end of the wireless module when the end of the wireless module, the receptacle RF connector and the connector end of the coaxial cable connector are receiving in the retention cavity and the coaxial cable go through the cable receiving groove.

2. The electrical connector assembly as described in claim 1 , wherein the cable receiving grooves is constructed with an upper eaves and lower eaves separated from each other.

3. The electrical connector assembly as described in claim 1 , wherein the retention member further defines a raised portion between the main base and the projecting portion, the raised portion is integrated with the main base without any elasticity in a condition that an outer edge of the end of the wireless module is retained between the raised portion and an inner edge of the end of the wireless module is pressed by the projecting portion with a smaller elasticity.

4. The electrical connector assembly as described in claim 1 , wherein the retention member defines two cable receiving grooves at opposite lateral sides of the main base, the two cable receiving grooves receiving two coaxial cables of two coaxial cable connectors, respectively.

5. A RF (Radio Frequency) coaxial cable connector assembly comprising: a cable connector comprising a RF connector end and a coaxial cable extending from the RF connector end; and a retention member comprising a main base, and an upper board and a lower board extending from the main base and defining a retention cavity between the upper board and the lower board; wherein the main base defines two cable receiving grooves at opposite lateral sides thereof, a projecting portion and a raised portion extending in the retention cavity and disposed between the two cable receiving grooves in a lateral direction respectively; wherein the RF connector end is received in the retention cavity and fitly stays with the upper board, the coaxial cable goes through one of the cable receiving grooves.

6. The RF coaxial cable connector assembly as claimed in claim 5 , wherein another cable receiving grooves is constructed by an upper eaves and a lower eaves separated from each other with a slot.

7. The RF coaxial cable connector assembly as claimed in claim 5 , wherein the projecting portion has a small elasticity in a vertical direction and the raised portion has no elasticity in the vertical direction.

8. An electrical connector assembly for use with a wireless module having a printed circuit board with a RF (Radio Frequency) receptacle connector mounted upon an upper surface thereon, comprising:
a RF plug connector including a lower cylindrical mating part defining a downward mating port in a vertical direction, and an upper connecting part defining a horizontally extending connecting port along a front-to-back direction;
a cable connected to the connecting port and extending rearwardly along said front-to-back direction;
a retention member mounted upon the cable and moveable along the front-to-back direction, said retention member defining a lower plate to upwardly intimately confront a bottom surface of the printed circuit board in the vertical direction, and an upper plate to downwardly intimately confront an upper face of the connecting part when the RF plug connector is mated with the RF receptacle connector with the retention member being moved to the front end of the upper connecting part.

9. The electrical connector assembly as claimed in claim 8 , wherein said lower plate and said upper plate are aligned with each other in an opposite manner in said vertical direction.

10. The electrical connector assembly as claimed in claim 8 , wherein a retention cavity is formed between the upper plate and the lower plate in said vertical direction, and a dimension of the retention cavity in said vertical direction is essentially equal to a combination of a thickness of the printed circuit board and a height of the mated RF plug and receptacle connectors.

11. The electrical connector as claimed in claim 10 , wherein said retention member includes a main base behind the retention cavity in the front-to-back direction, and a receiving groove extends through the main base to receive the cable therein.

12. The electrical connector as claimed in claim 11 , wherein said receiving groove is outwardly open to an exterior in a lateral direction perpendicular to both said front-to-back direction and said vertical direction for installation of the cable thereinto.

13. The electrical connector as claimed in claim 11 , wherein the main base forms an inclined lower face to comply with the lower plate in a front region and an end of the receiving groove in a rear region.

14. The electrical connector assembly as claimed in claim 10 , wherein the upper plate is equipped with an inward projection portion opposite to the lower plate, and a gap formed between the projection portion and the lower plate is close to a thickness of the printed circuit board.

15. The electrical connector assembly as claimed in claim 14 , wherein a dimension of the gap in the vertical direction is less than one half of that of the retention cavity in the vertical direction.

16. The electrical connector assembly as claimed in claim 10 , wherein said retention cavity is exposed to an exterior in a lateral direction perpendicular to both said front-to-back direction and said vertical direction.

17. The electrical connector assembly as claimed in claim 8 , wherein said retention member defines a retention cavity with a dimension, in a lateral direction perpendicular to both said front-to-back direction and said vertical direction, to receive a pair of plug connectors and the associated two cables.

18. The electrical connector assembly as claimed in claim 17 , wherein the retention member includes a projection portion to separate the retention cavity into two sub-cavities to receive the two plug connectors, respectively.

19. The electrical connector as claimed in claim 8 , wherein a thickness of the retention member in the vertical direction is larger than that of the wireless module in the vertical direction.

20. The electrical connector as claimed in claim 8 , wherein the RF receptacle connector is mounted upon an edge region of the printed circuit board, and when the receptacle connector and the plug connected are mated with each other, the cable extends beside and beyond the wireless module.
