Abstract

A connector assembly includes a first connector and a second connector mating with the first connector. The first connector defines a first mating face, a first cleaning device disposed in the first mating face and a stiff first mating portion exposed upon the first mating face. The second connector defines a second mating face, a second cleaning device disposed in the second mating face and a stiff second mating portion exposed upon the second mating face. During mating the first connector to the second connector along the mating direction, the first cleaning device wipes the second mating face for wiping away the dirty attached to the second mating portion while the second cleaning device wipes the first mating face for wiping away the dirty attached to the first mating portion until the first and second mating portions mated with each other.

First claim

What is claimed is:

1. A connector assembly including a first connector and a second connector mating with the first connector in a mating direction for signal transmission, the first connector comprising:
a first mating face and a first cleaning device disposed in the first mating face; and
a stiff first mating portion exposed upon the first mating face and located behind the first cleaning device in the mating direction;
the second connector comprising: a second mating face and a second cleaning device disposed in the second mating face; and
a stiff second mating portion exposed upon the second mating face and located in front of the second cleaning device in the mating direction; wherein
during mating the first connector to the second connector along the mating direction, the first cleaning device wipes the second mating face for wiping away dust attached to the second mating portion while the second cleaning device wipes the first mating face for wiping away dust attached to the first mating portion until the first and second mating portions mated with each other; wherein
the first cleaning device protrudes out of the first mating face and the second cleaning device protrudes out of the second mating face so as to form a gap formed between the first mating face and the second mating face when the first connector and the second connector are fully mated with each other.

2. The connector assembly as claimed in claim 1 , wherein the first and second mating faces both are parallel to the mating direction.

3. The connector assembly as claimed in claim 1 , wherein the first mating portion and the first mating face are disposed in a same plane.

4. The connector assembly as claimed in claim 1 , wherein the second connector defines a second housing having a receiving cavity for receiving the first connector therein, the second mating face is disposed in the receiving cavity and the second cleaning device is located adjacent to an opening of the receiving cavity.

5. The connector assembly as claimed in claim 4 , wherein the second mating portion and the second mating face are disposed in a same plane.

6. The connector assembly as claimed in claim 1 , wherein a first height of the first cleaning device is larger than a second height of the second mating portion in a vertical direction perpendicular to the mating direction, while a third height of the second cleaning device is larger than a fourth height of the first mating portion in the vertical direction.

7. The connector assembly as claimed in claim 1 , wherein both the first cleaning device and the second cleaning device are defined as soft brush.

8. The connector assembly as claimed in claim 1 , wherein both the first cleaning device and the second cleaning device are defined as wiper made of elastic rubber.

9. A connector assembly comprising:
a first connector forming a first mating face with a first optical element thereon, said first optical element defining a first mating portion thereon;
a first cleaning device located on the first mating face and in front of the first optical element along a mating direction;
a second connector forming a receiving cavity to receive the first connector therein in said mating direction, and defining internally a second mating face exposed to said receiving cavity in a lateral direction perpendicular to said mating direction and facing toward the first mating face during mating;
a second optical element located upon the second mating face with a second mating portion thereon; and
a second cleaning device located on the second mating face and in front of the second optical element in said mating direction; wherein
the first connector and the second connector are structured to have the first cleaning device and the second cleaning device offset away from each other in a lateral direction without excessive abrasion therebetween during an initial stage of mating while being urged toward each other in a successive stage during mating to have the first cleaning device efficiently wipe the second mating portion and the second cleaning device efficiently wipe the first mating portion; wherein
the first cleaning device protrudes out of the first mating face and the second cleaning device protrudes out of the second mating face so as to form a gap formed between the first mating face and the second mating face in the lateral direction when the first connector and the second connector are fully mated with each other.

10. The connector assembly as claimed in claim 9 , wherein a width of the first connector is smaller than that of the receiving cavity, and one of said first connector and said second connector is equipped with a spring device to urge the first connector to move in a lateral direction to have the first mating face and the second mating face confront each other with said gap therebetween when the first connector and the second connector are fully mated with each other.

11. The connector assembly as claimed in claim 10 , wherein said spring device is disposed in the second connector, and the spring device and the second cleaning device are located by two opposite sides of receiving cavity in the lateral direction, respectively.

12. The connector assembly as claimed in claim 9 , wherein the first cleaning device is located at a front end of the first connector, and the second cleaning device is located at a front end of the second connector.

13. The connector assembly as claimed in claim 12 , wherein at least a chamfered structure is formed at either the front end of the first connector or the front end of the second connector so as to have the first cleaning device and the second cleaning device offset away from each other in the lateral direction for avoiding excessive abrasion.

14. The connector assembly as claimed in claim 13 , wherein a width of the first connector in the lateral direction is smaller than that of the receiving cavity so as to have the first mating face and the second mating face confront each other with said gap therebetween when the first connector and the second connector are fully mated together.

15. A connector assembly comprising:
a first connector adapted to be mated with a second connector along a mating direction, said first connector including:
a first mating face exposed in a first lateral direction perpendicular to said mating direction;
a first optical element disposed upon the first mating face with a first mating portion thereon;
a first cleaning device disposed upon the first mating face, located in front of the first mating portion and backwardly moveable along said mating direction;
the second connector including:
a second mating face exposed in a second lateral direction opposite to said first lateral direction;
a second optical element disposed upon the second mating face with a second mating portion thereon for confronting the first mating portion during mating; and
at least a pushing post urging the first cleaning device to move backward in a direction opposite to the mating direction during mating to wipe the first mating portion; wherein
the first cleaning device protrudes out of the first mating face and the second cleaning device protrudes out of the second mating face so as to form a gap formed between the first mating face and the second mating face along either one of the first lateral direction and the second lateral direction when the first connector and the second connector are fully mated with each other.

16. The connector assembly as claimed in claim 15 , wherein said pushing post is immoveable in said mating direction.
