As a further improvement of the present invention, the end of the locking arm is provided with a protruding locking portion, and the locking arm is generally cantilevered.

As a further improvement of the present invention, the driving arm is stamped from the locking arm.

As a further improvement of the present invention, the driving arm is located between the fixing portion and the locking portion.

As a further improvement of the present invention, the housing is provided with a sliding slot, and the unlocking member is provided with an extending portion extending from the end of the connecting portion and slidable in the sliding slot, and the slot is provided in the middle of the slot. a blocking portion that protrudes upward, and the extending portion is provided with a limiting groove for receiving the blocking portion.

As a further improvement of the present invention, the housing is provided with a sliding slot, and the housing is provided with an inwardly recessed receiving space for receiving the driving arm and the locking arm.

As a further improvement of the present invention, the small pluggable connector further includes a circuit board housed in the housing.

Compared with the prior art, the small pluggable connector of the present invention has at least the following enhancements: the driving arm is directly pulled by the unlocking member to directly deform the driving arm, thereby unlocking, and after releasing the unlocking member, the locking member can be borrowed. It is restored by its own elastic force, and the overall structure is simple and the manufacturing cost is low.

Referring to the first to fifth figures, a specific embodiment of the present small form factor pluggable connector 100 will be described in detail below with reference to the accompanying drawings.

The small-sized pluggable connector 100 includes a housing 10 and a locking mechanism 20 mounted on the housing 10. The locking mechanism 20 includes a locking member 21 and is connected to the locking member 21 and can drive the locking button. The unlocking member 22 of the piece 21 is unlocked. In this embodiment, the small-sized pluggable connector 100 further includes a circuit board 30 received in the housing 10, and a cover 40 that is disposed on the unlocking member 22 and fixed to the housing 10, and the cover plate is 40. The screw 50 fixed to the casing and the metal member 60 sleeved on the casing 10 for shielding.

The housing 10 includes an upper housing 11 and a lower housing 12 that are fastened to each other. A receiving cavity 13 for receiving the circuit board 30 and a through-the housing 10 are disposed between the upper housing 11 and the lower housing 12 . The rear end surface 14 is connected to the receiving groove 15 of the receiving cavity 13, and the receiving groove 15 is inserted into a cable (not shown). The housing 10 has a rectangular parallelepiped shape as a whole, and when used, the housing 10 is mostly inserted in abutting connection. In the connector (not shown). The upper housing 11 is provided with a receiving space 16 for receiving the locking mechanism 20 and a sliding slot 17 extending through the rear end surface 14 and connected to the receiving space 16 for restricting the movement of the unlocking member 22 . An upwardly convex projection 18 is disposed in the middle of the sliding groove 17. The upper housing 11 is also provided with a slot 19 that spans the receiving space 16.

The locking member 21 includes a fixing portion 212 mounted on the upper casing 11 , a locking arm 213 extending forward from the fixing portion 212 , and a locking arm 213 extending from the locking arm 213 and the upper housing 11 . The driving arm 214 is between the locking arm 215 and the locking portion 215 which is convex upward at the end of the locking arm 213. The fixing portion 212 is mounted in the slot 19, and the locking arm 213 is received in the receiving space 16 and has a cantilever shape as a whole. The driving arm 214 is located between the fixing portion 212 and the locking portion 215. For example, the driving arm 214 is pulled downward to move the locking arm 213, so that the locking arm 213 is contracted into the receiving space 16 to realize the locking mechanism 20. Unlock. The driving arm 214 is stamped and formed on the locking arm 213, and is conveniently manufactured. The driving arm 214 is further provided with a rotating shaft 216 for connecting with the unlocking member 22, and the rotating shaft 216 extends from the end of the driving arm 214 to both sides. If it is convenient, the unlocking member 22 pulls the driving arm 214.

The unlocking member 22 includes a connecting portion 221 connected to the rotating shaft 216, an extending portion 222 extending rearward from the end of the connecting portion 221, and a collar 223 and a pull ring 224 extending rearward from the extending portion 222. The connection between the connecting portion 221 and the rotating shaft 216 is rotatable, and the direction of the force acting on the driving arm 214 by the connecting portion 221 is also changed as the latching arm 213 is deformed during the pulling process. , the drive fastener 21 is better driven to unlock. The extending portion 222 is received in the sliding groove 17 and slidable in the front-rear direction in the sliding groove 17 , and the extending portion 222 is further provided with the protruding portion 18 . The limiting groove 225 can limit the maximum stroke of the unlocking member 22 to be stretched backward by defining the length of the limiting groove 225, thereby preventing the plastic deformation of the locking member 21 caused by excessive stretching, and the locking member 22 can be better restricted only along the length. Slide in the front and rear direction. The collar 223 and the pull ring 224 can better facilitate the user to pull the unlocking member 22, and the overall design is more user-friendly.

The cover plate 40 covers the extension portion 222 and the fixing portion 212. The screw 50 tightly fixes the cover plate 40, the upper casing 11 and the lower casing 12. The metal member 60 is wrapped around the housing 10 near the rear end surface 14. When the small pluggable connector 100 is connected to the mating connector, the metal member 60 can better adjust the housing 10 and the docking. The gap between the connectors.

When assembled, the circuit board 30 is received in the housing 10, and the locking mechanism 20 is mounted and fixed on the upper housing 11. The cover 40 covers the extension portion 222, and the screw 50 is riveted. The cover plate 40 and the upper and lower casings (11, 12) are press-fitted. The metal member 60 is sleeved on the casing 10 near the rear end surface 14.
