Abstract

An electrical connector assembly includes first and second electrical connectors that are interconnected electrically by engagement of pins and pins holes. The first electrical connector further includes two sleeve units sleeved fittingly and respectively on two positioning members of the second electrical connector to prevent relative movement between the first and second electrical connectors in a transverse direction of the contact pins.

Claims

1. An electrical connector assembly comprising:

a first electrical connector including a first housing, a first engaging portion extending outwardly from said first housing, and a fixing unit disposed on said first housing and located adjacent to said first engaging portion; and

a second electrical connector having one end adapted to be connected to an electronic device and the other end connected detachably to said first electrical connector, said second electrical connector including a second housing, a second engaging portion that extends outwardly from said second housing and that is connected to said first engaging portion, and a positioning member disposed fixedly on said second housing and located adjacent to said second engaging portion;

wherein one of said first and second engaging portions includes a plurality of parallel contact pins disposed fixedly thereon, and the other one of said first and second engaging portions includes a plurality of pin holes formed therein for receiving respectively said contact pins therein to form an electrical connection between said first and second electrical connectors, said positioning member engaging said fixing unit so as to prevent relative movement between said first and second electrical connectors in an axial direction of said pins;

wherein said first electrical connector further includes a sleeve unit disposed fixedly on said first housing around said fixing unit, said sleeve unit being sleeved fittingly on said positioning member when said first engaging portion and said second engaging portion are interconnected, whereby relative movement between said first and second electrical connectors in a transverse direction of said contact pins is prevented;

wherein said positioning member is constructed as a hexagonal nut, said sleeve unit being constructed as a sleeve; and

wherein said fixing unit is a bolt that is disposed movably and rotatably in said first housing and that extends into said sleeve unit, the length of said sleeve unit that protrudes out from said first housing being less than or equal to the length of said first engaging portion that protrudes out of said first housing.

2. The electrical connector assembly as claimed in claim 1, wherein said sleeve is circular.

3. The electrical connector assembly as claimed in claim 2, wherein said sleeve includes two diametrically opposed notches that divide said sleeve into two opposite arcuate ribs.

4. The electrical connector assembly as claimed in claim 1, wherein said sleeve is generally rectangular, and has two opposite notches that divide said sleeve into two opposite U-shaped ribs.

5. An electrical connector assembly comprising:

a first electrical connector including a first housing, a first engaging portion extending outwardly from said first housing, and a fixing unit disposed on said first housing and located adjacent to said first engaging portion; and

a second electrical connector having one end adapted to be connected to an electronic device and the other end connected detachably to said first electrical connector, said second electrical connector including a second housing, a second engaging portion that extends outwardly from said second housing and that is connected to said first engaging portion, and a positioning member disposed fixedly on said second housing and located adjacent to said second engaging portion;

wherein one of said first and second engaging portions includes a plurality of parallel contact pins disposed fixedly thereon, and the other one of said first and second engaging portions includes a plurality of pin holes formed thereon for receiving respectively said contact pins therein to form an electrical connection between said first and second electrical connectors, said positioning member engaging said fixing unit so as to prevent relative movement between said first and second electrical connectors in an axial direction of said pins;

wherein said first electrical connector further includes a sleeve unit disposed fixedly on said first housing around said fixing unit, said sleeve unit being sleeved fittingly on said positioning member when said first engaging portion and said second engaging portion are interconnected, wherein relative movement between said first and second electrical connectors in a transverse direction of said contact pins is prevented; and

wherein said positioning member is generally shaped as a plate that is parallel to said contact pins, said plate having a hooking end, said fixing unit having a slot to engage said hooking end, said sleeve unit being constructed as an elliptical sleeve to sleeve around said plate.
