Obviously, the application fields of the male connector and the female connector are many, such as a charging plug and a socket of an electronic product, a male plug and a female socket of a USB, and the like. In this embodiment, the male connector and the female connector are correspondingly configured as a male head and a female socket of a USB for description.

Referring to fig. 1, in an embodiment of the present invention, the elastic latch 10 includes: mounting portion 11, pressing portion 12, connecting portion 13, and locking portion 14.

The mounting portion 11 is mounted on the male connector 100, and the pressing portion 12 is pressed by a user. The mounting portion 11 is disposed in parallel with the pressing portion 12, and the same side of the mounting portion 11 and the pressing portion 12 is connected by a connecting portion 13. Wherein, the contained angle between installation department 11 and the connecting portion 13 is the acute angle setting, and installation department 11 and the contained angle of pressing between the portion 12 of pressing are the obtuse angle setting, so can make the pressing of pressing the portion 12 convenient.

The locking portion 14 includes two elastic arms 141 disposed in parallel, the two elastic arms 141 are disposed at an interval in the length direction (the direction of arrow a in fig. 1) of the pressing portion 12, one end of each elastic arm 141 is connected to one side of the pressing portion 12 departing from the connecting portion 13, the other end of each elastic arm 141 extends in the direction of departing from the pressing portion 12, and one end of each elastic arm 141 departing from the pressing portion 12 is bent in the direction of departing from the mounting portion 11 to form a lock 1411. With such an arrangement, the latch 1411 can be formed by directly bending the end of the elastic arm 141, so that the latch 1411 can be conveniently formed. The pressing portion 12 is raised from the two elastic arms 141 to facilitate pressing of the pressing portion 12.

Specifically, the locking portion 14 is U-shaped and has two elastic arms 141 and an elastic connecting arm 142 connecting the two elastic arms 141, and one side of the elastic connecting arm 142 departing from the two elastic arms 141 is connected to one side of the pressing portion 12 away from the connecting portion 13, so that the two elastic arms 141 are conveniently formed.

In this embodiment, the elastic latch 10 is formed by punching and bending a metal sheet to form the mounting portion 11, the pressing portion 12, the connecting portion 13, the two elastic arms 141, and the two latches 1411. So set up, conveniently at production end shaping elasticity hasp 10. In other embodiments, the resilient latch 10 may be injection molded.

It will be appreciated that during extended use, the latch 1411 may frequently switch between snap-fitting and restraint-releasing, causing wear to the latch 1411, which may affect the tightness of the latch 1411 during snap-fitting. Thus, wear resistant coatings, such as tungsten carbide coatings, chromium carbide coatings, and the like, may be plated or coated on the surface of the shackle 1411 to enhance the wear resistance of the shackle 1411 and extend the service life of the shackle 1411.

Thus, the present invention is provided by applying the elastic locking buckle 10 to the male connector 100 (fig. 1). When the male connector 100 is mated with the female connector 200 (fig. 7) by insertion, the pressing portion 12 is pressed first, and the two elastic arms 141 and the two latches 1411 are indirectly pressed together. Then, the male connector 100 is fitted to the female connector 200 while the pressing portion 12 is kept pressed. Then, the pressing of the pressing portion 12 is released, so that the pressing portion 12 and the two elastic arms 141 drive the two latches 1411 to be in buckling engagement with the female connector 200 under the effect of their own resilience, and the male connector 100 and the female connector 200 can be inserted and engaged. When the male connector 100 and the female connector 200 are disengaged from each other by inserting them, the pressing portion 12 is pressed, the elastic arms 141 and the latches 1411 are indirectly pressed together, and the latches 1411 and the female connector 200 are disengaged from each other. Subsequently, the male connector 100 is pulled out from the female connector 200 while the pressing portion 12 is kept pressed. Then, the pressing portion 12 is released, so that the pressing portion 12 and the two elastic arms 141 bring the two latches 1411 back to the initial position under the self-elastic force. So set up, and then can effectually prevent that male connecting piece 100 from producing unexpected the droing when cooperateing with female connecting piece 200.

And, on the premise that the male connector 100 and the female connector 200 conform to the USB association standard, the elastic latch 10 is additionally provided, so that the application range of the product is expanded, and the elastic latch can be applied to a strict use environment (such as vibration, foolproof children, wrong plugging and unplugging and the like), so that the performance of the product is maximized, the stability of the product is improved, and data loss caused by accidental separation of the male connector 100 during data transmission is avoided, thereby further meeting the requirements of market diversification and high-end. In addition, the addition of the elastic lock 10 does not increase the insertion and extraction action, and the insertion and extraction action and sequence are consistent with those of the original insertion and extraction action, so that the insertion and extraction efficiency of the male connector 100 is not reduced.
