Description

Small pluggable connector

The present invention relates to a plug connector, and more particularly to a small form factor pluggable connector having a latch and unlock mechanism.

Currently, Small Form-factor Pluggable (SFP) connectors are used for common high-speed direct-connect cables and high-speed fiber optic cables. Generally, a locking mechanism is disposed on the SFP connector. When the SFP connector is docked with a socket connector, the SFP connector needs to first protrude into a mask member, and the SFP connector is utilized by the locking mechanism. It is fixed into the mask to ensure its docking safety with the socket connector. When the connection needs to be disconnected, the SFP connector has to be separated from the mask by an unlocking mechanism for quick withdrawal.

However, as connectors become smaller and smaller, the density of the socket connectors in the electronic device is gradually increasing, and the mechanism for fixing or separating the SFP connector from the mask member becomes increasingly complicated, and its operation is also complicated. It has become more difficult.

Therefore, it is necessary to provide a new small pluggable connector that simplifies its latching and unlocking mechanism to further simplify its unlocking operation.

As shown in FIG. 2 and FIG. 3 , the fixing rod 42 can be inserted into the through hole 251 of the outer cover 20 and the shaft hole 411 of the rotating member 41 , so that the rotating member 41 is pivotally connected to the outer cover 20 . .

As shown in FIG. 2 and FIG. 3, the elastic member 43 is located in the recess 24 of the outer cover 20 and is located below the latching arm 412 of the rotating member 41 for providing elastic force for the latch and the unlocking. . Specifically, the elastic member 43 is placed in the elastic member accommodating chamber 240 (shown in FIG. 5) of the outer cover 20. When the holding arm 412 is forced to rotate downward by an external force, the elastic member 43 is compressed, and when the external force is released, the elastic member 43 is restored to the original state and the holding arm 412 is lifted up. In detail, generally, the elastic member 43 is in a free state, and the hook 413 on the holding arm 412 protrudes from the first surface 21 of the outer cover 20 (as shown in FIG. 1). When the small pluggable connector 1 enters the mask member 9 (shown in FIG. 6), the hook 413 is pressed down by the inner wall surface of the mask member 9, but due to the latching arm 412 The elastic member 43 is placed underneath, so that the buckle 413 can be downwardly displaced by the pressing arm 412 pressing the elastic member 43 to smoothly enter the mask member 9 when the small pluggable connector 1 is After fully entering the mask member 9, the hook 413 can automatically rebound into a buttonhole 90 on the mask member 9, thereby fixing the small pluggable connector 1 to the mask member 9. , preventing it from coming off the mask member 9.

In this embodiment, as shown in FIG. 3, the elastic member 43 is a cylindrical spring, and the elastic member 43 is a cylindrical spring. The top end 430 of the cylindrical spring is placed on the boss 418 of the latching arm 412, and the bottom end 431 of the cylindrical spring is received in the elastic member receiving cavity 240 (shown in FIG. 5) of the outer cover 20. .

As shown in FIG. 2, the actuator 44 is slidably assembled to the outer cover 20, and includes a first end 440 and a second end 441, wherein the first end 440 is assembled The fixing passage 25 of the outer cover 20 is inserted between the main body 410 of the rotating member 41 and the bottom surface of the fixing passage 25; the second end portion 441 extends rearward from the first end portion 440 and forms a longer length. The pull strap is for the user to pull the first end 440 backward when unlocking. In this embodiment, an opening 442 is formed on the first end portion 440 to match the protrusion 250, and the length dimension of the opening 442 is larger than the length dimension of the protrusion 250, and the width dimension of the two is substantially the same. When the actuating member 44 is assembled to the outer cover 20, the projection 250 located on the outer cover 20 can fit into the opening 442 of the actuating member 44, and the actuating member 44 can also be accommodated in the opening 442. Move back and forth within the distance. In addition, a convex slat 443 is formed on the top surface of the first end portion 440. The front surface of the convex hull 443 is the same as the front side wall 4140 of the inner concave portion 414 of the rotating member 41. Therefore, the convex hull 443 can be accommodated. In the inner recess 414 of the rotating member 41. Further, a fixing hole 444 is formed in the convex hull 443 (reference numeral 444 is shown in Fig. 3).

The U-shaped connecting member 45 has two substantially parallel free edges 450 and 451. The first free edge 450 is inserted and rotatably fixed in the fixing hole 444 of the actuating member 44, and the second free edge 451 of the U-shaped connecting member 45 abuts against the inner recess 414 of the rotating member 41. After the side wall 4142. In the present embodiment, the U-shaped connector 45 is a U-shaped ring.

Please refer to FIG. 5 and FIG. 6 at the same time. In actual use, the small pluggable connector 1 is inserted into the mask member 9 with the top surface facing downward, and the hook 413 enters the mask member 9. of The inside of a buttonhole 90 is blocked by the inner edge 901 of the buttonhole 90, thereby preventing the small pluggable connector 1 from being detached from the mask member 9. When the unlocking is required, the second end 441 of the actuating member 44 can be pulled back (see FIG. 2), thereby driving the first end 440 to move rearward with the first free edge 450 of the U-shaped connecting member 45. Since the second free edge 451 of the U-shaped connector 45 is blocked by the rear sidewall 4142 of the inner recess 414 and cannot be translated backward, the second free edge 451 can only rotate upward with the first free edge 450 as a rotating shaft, thereby A portion of the rotating member 41 located behind the shaft hole 411 is upwardly raised; and a portion of the rotating member 41 located in front of the shaft hole 411 (for example, the holding arm 412) will be downward with the fixing rod 42 as a rotating shaft Turn. At this time, the holding arm 412 presses the elastic member 43 downward, so that the hook 413 is caught in the recess 24 of the outer cover 20 and is withdrawn from the button hole 90 of the mask member 9, thereby the small pluggable The connector 1 can be pulled out of the mask member 9. After the small pluggable connector 1 is pulled out, the latch and unlocking mechanism 40 will return to the initial state again under the action of the elastic member 43.
