Detailed Description

Referring to fig. 1 to 8, the present invention discloses a connector 100. In the illustrated embodiment of the present invention, the connector 100 is an SFP cable connector, which is configured to mate with an SFP interface on a communication device; of course, in other embodiments, the connector 100 may be other types of connectors.

The connector 100 includes a housing 1, a terminal 2 for mating with a mating connector (not shown), a cable 3 electrically connected to the terminal 2, and an unlocking mechanism 4 mounted on the housing 1. In the illustrated embodiment of the present invention, the housing 1 is made of a metal material, and has a substantially rectangular parallelepiped shape; the shell 1 is provided with an opening 11 at the front end thereof, and the rear end of the shell 1 is provided with an elastic clamping piece 12 for strengthening the butt joint with the butting connector.

In the illustrated embodiment of the invention, the connector 100 is provided with a tongue plate 20 located in the opening 11. The terminals 2 are metal conductive strips 21 exposed at the front end of the tongue plate 20. The tongue plate 20 and the conductive metal plate 21 may be formed by a circuit board.

Referring to fig. 3 to 6, the unlocking mechanism 4 includes a rotating member 41, a force transmission arm 42 for driving the rotating member 41 to rotate, a pull strap 43 connected to the force transmission arm 42, and an elastic member 44 for providing a restoring force to the rotating member 41. In the illustrated embodiment of the present invention, the elastic member 44 is a compression spring. The rotating member 41 is provided with a rotating shaft 411, a latch arm 412 located at one side of the rotating shaft 411, and a pressing arm 413 located at the other side of the rotating shaft 411. In the embodiment of the present invention, the rotating shaft 411 protrudes from the latch arm 412 and the pressing arm 413 toward both sides. Of course, in other embodiments, the rotating shaft 411 may have other forms, such as a recessed shaft hole, as long as it can be used as a rotating center. The latch arm 412 is provided with a hook 4121 for latching with the mating connector; the pressing arm 413 is provided with a distal end portion 4131 fitted to the transmission arm 42.

Referring to fig. 4, the transmission arm 42 has a front wall 421, a rear wall 422, two side walls 423 connecting the front wall 421 and the rear wall 422, and a hollow portion 424 located between the front wall 421 and the rear wall 422, wherein the front wall 421 has a groove 4211 for accommodating the pressing arm 413, and a shoulder portion 4212 located at the bottom of the groove 4211. The pressing arm 413 is located between the two sidewalls 423. The hollow portion 424 is used for accommodating the end portion 4131. Referring to fig. 6, the end portion 4131 and the shoulder portion 4212 are provided with guiding surfaces 414 which cooperate with each other. The pull tab 43 is located at the rear end of the connector 100 and is attached to the rear wall 422.

Referring to fig. 6 to 8, the transmission arm 42 can be translated (moved horizontally backward as shown in fig. 8) by the pull belt 43 under the action of external force; under the guidance of the guiding surface 414, the shoulder portion 4212 can press against the lower side of the pressing arm 413 and raise the pressing arm 413, that is, the transmission arm 42 abuts against the pressing arm 413 and drives the pressing arm 413 to rotate counterclockwise around the rotating shaft 411; at the same time, the latch arm 412 rotates counterclockwise around the rotating shaft 411 synchronously, so that the position of the hook 4121 is lowered to unlock the mating connector. In this case, pulling the pulling tape 43 further backward enables the connector 100 to be completely detached from the mating connector. Referring to fig. 8, the resilient member 44 is pressed by the latch arm 412 and compressed downward. When the external force is removed, the elastic member 44 rotates the latch arm 412 clockwise by its own restoring force to return to the original state (see fig. 7).

Compared with the prior art, the force transmission arm 42 of the utility model can translate under the action of external force, and the rotation of the rotating part 41 is driven by the translation of the force transmission arm 42, so that the hook 4121 unlocks the butting connector, the structural design of the unlocking mechanism 4 is simplified, and the structural reliability of the unlocking mechanism 4 is improved; in addition, the rotation of the rotating member 41 is driven by the translation of the transmission arm 42, so that the space occupied by the transmission arm 42 can be reduced, and the space occupied by the whole connector 100 can be reduced.

The above embodiments are only used for illustrating the present invention and not for limiting the technical solutions described in the present invention, and the understanding of the present specification should be based on the technical people in the related art, for example, the descriptions of the directions such as "front", "back", "left", "right", "up", "down", etc., although the present specification has described the present invention in detail with reference to the above embodiments, the ordinary skilled in the art should understand that the technical people in the related art can still modify or substitute the present invention, and all the technical solutions and modifications thereof that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
