[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0019] See also Figures 1-6The utility model provides an embodiment: a kind of locking mechanism of electric connector, including plug shell 1 and cooperation shell 2, and still be equipped with lock catch 10 on the plug shell 1;Rotary mounting is equipped with locking piece 21 on the plug shell 1, and the end of locking piece 21 away from the cooperation shell 2 is slidably fitted with the locking pin 20 equipped;When the plug shell 1 is connected with the cooperation shell 2, rotating locking piece 21 to make the first protruding portion 22 equipped on locking piece 21 be connected with the first connecting portion 11 equipped in one end of lock catch 10, to complete the locking of one side of locking piece 21;The locking pin 20 is slid to locking piece 21, to make the second protruding portion 25 equipped on the locking pin 20 be connected with the second connecting portion 12 equipped in the other end of lock catch 10, to complete the locking of the other side of locking piece 21.

[0020] As a result, after locking piece 21 lock catch 10 contact, first protruding portion 22 is connected with first connecting portion 11, and the locking action on one side of locking piece 21 can be completed;Then push locking pin 20 until second protruding portion 25 is connected with second connecting portion 12, and the locking action on the other side of locking piece 21 can be completed.

[0021] When locking piece 21 is in locking state, both sides of locking piece 21 have locking ability, so that the locking state of the device is kept durable and reliable, and the phenomenon of loosening between cooperation shell 2 and plug shell 1 is effectively solved.

[0022] Further, since the locking pin 20 is slidably guided by the sliding groove 23 on the locking piece 21, the sliding direction of the locking pin 20 can be limited, and the locking pin 20 can be smoothly and reliably contacted or separated from the lock catch 10.

[0023] Further, since the locking pin 20 is slidably guided by the sliding groove 23 on the locking piece 21, the sliding direction of the locking pin 20 can be limited, and the locking pin 20 can be smoothly and reliably contacted or separated from the lock catch 10.

[0024] On the basis of the above scheme, the two sides of the lock 10 are provided with limiting posts 13, and the locking pin 20 is guided to be connected with the lock 10 smoothly through the limiting posts 13. Therefore, the gap between the limiting posts 13 can be used to guide the locking pin 20 to slide into the sliding groove 23, and when the locking pin 20 is inserted into the sliding groove 23, the limiting posts 13 can prevent the locking piece 21 from swinging, so that the locking state of the device can be kept stable and durable, and even when the two sides of the locking piece 21 are collided by external force, the locking piece will not swing along the left and right sides of the lock 10.

[0025] Further, since the lock 10 is a elastic buckle, the first connecting part 11 of the lock 10 can be separated from the first protruding part 22 by pressing downward, and the lock 10 can be automatically reset after the external force disappears. Therefore, the separation of the first connecting part 11 and the second protruding part 25 can be realized by pressing the lock 10, and then the unlocking action of the locking piece 21 can be facilitated.

[0026] Further, since the upper wall surface of the lock 10 is provided with anti-skid lines 14, the phenomenon of slipping during pressing can be avoided, and the left side of the anti-skid lines 14 is provided with an inclined surface 15, so that the first protruding part 22 can be smoothly moved below the first connecting part 11 during the locking process of the locking piece 21.

[0027] The embodiments of the utility model are described in detail above combined with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
