Abstract

A plug connector to be inserted into a receptacle cage having a latching tab includes a housing and a releasing mechanism mounted on the housing. The housing has a top wall, a bottom wall and two side walls interconnecting the top wall and the bottom wall together. The housing includes a first flange extending a first preselected distance from the top wall and a second flange extending a second preselected distance from the bottom wall. A width of the second flange is larger than a width of the first flange. The releasing mechanism comprises a pair of actuator arms movably attached to the sidewalls along a mating direction of the plug connector and a horizontal portion integrally connected between the actuator arms.

Claims

1. A plug connector configured for latching engagement with a receptacle cage having an inwardly extending latching tab, comprising:

a housing comprising a top wall, a bottom wall opposite to the top wall, and two opposite sidewalls connecting with the top wall and the bottom wall, the top wall extending a preselected length to define a first flange and the bottom wall extending a preselected length to define a second flange, a width of the first flange being smaller than a width of the second flange;

a releasing mechanism assembled to the housing, the releasing mechanism comprising a pair of actuator arms movably attached to the sidewalls along a mating direction of the plug connector and a horizontal portion integrally connected between the actuator arms.

2. The plug connector as claimed in claim 1, wherein the actuator arm comprises an arcuate bend portion linking to the horizontal portion.

3. The plug connector as claimed in claim 2, wherein the bend portion lies on a vertical main plane of the actuator arm.

5. The plug connector as claimed in claim 1, wherein the releasing mechanism comprises a pull member attached to the horizontal portion.

6. The plug connector as claimed in claim 1, wherein the releasing mechanism comprises two protrusion portions extending toward the top wall and a connecting portion connected between the two protrusion portions.

7. The plug connector as claimed in claim 6, wherein the connecting portion comprises a first portion and a second portion engaged with the first portion.

8. The plug connector as claimed in claim 1, wherein each of the actuator arms comprises at least one tab disposed at a front portion of the actuator arm, and each of the sidewalls defines a limiting groove for receiving a corresponding tab.

9. The plug connector as claimed in claim 1, wherein the actuator arm has an actuating end extending forwardly and a pair of slits extending rearwardly beside the actuating end to increase an elastic deformation length of the actuating end.

10. The plug connector as claimed in claim 9, wherein each of the actuator arms comprises a first part located between the slits and a second part located outside of the slits, the first part having a width measured along an up-to-down direction equal to a width of the actuator end along the direction.

11. A plug connector for latching into a receptacle cage with a pair of resilient inwardly extending locking tabs, comprising:

a housing defining opposite top and bottom walls in a first direction and a pair of opposite sidewalls in a second direction perpendicular to said first direction to commonly defining a receiving space with a mating port located in a front portion of the receiving space, said top wall defining a first flange and said bottom wall defining a second flange, said first flange being smaller than said second flange in the second direction;

a releasing mechanism attached to the housing and back and forth moveable relative to the housing along a third direction perpendicular to both said first direction and said second direction, said releasing mechanism defining at least one actuating arm located upon one of the sidewalls.

12. The plug connector as claimed in claim 11, wherein a printed circuit board is positioned in the mating port with a dimension between those of the first flange and the second flange in the second direction.

13. The plug connector as claimed in claim 11, wherein said releasing mechanism includes two said actuating arms respectively located on two sidewalls and linked by a horizontal portion where forces are applied to move releasing mechanism.

14. The plug connector as claimed in claim 13, wherein the releasing mechanism comprises a pull member attached to the horizontal portion.

15. The plug connector as claimed in claim 13, wherein said releasing mechanism further includes a connecting portion linked between said two actuating arms and opposite to said horizontal portion in said first direction.

16. The plug connector as claimed in claim 13, wherein each of said actuating arms defining at a front end region thereof an actuating end and a restriction tab with a slit therebetween in the third direction;

wherein said actuating end is adapted to urge the corresponding locking tab outwardly in the second direction for unlocking the plug connector from the receptacle cage when the plug connector and the receptacle cage are mated with each other while the restriction tab defines an edge region received in a limiting groove of the housing to restrict the front end region of the actuating arm from moving in the second direction.

17. The plug connector as claimed in claim 16, wherein each of the actuating arms includes two said restriction tabs respectively located by two sides of the actuating end in the first direction each with the corresponding slit therebetween.

18. The plug connector as claimed in claim 16, wherein said limiting groove extends along the third direction to allow the edge region of the restriction tab to back and forth move therein.
