[0045] The following is in conjunction with the appendix Figure 1-5 The connector double-sided locking mechanism of this utility model embodiment is described in detail.

[0046] Reference Figure 1 This utility model proposes a double-sided locking mechanism for a connector, characterized in that it includes a socket-side locking mechanism 100 and a plug-side locking mechanism 200. The socket-side locking mechanism 100 is disposed in the socket 300 of the connector, and the plug-side locking mechanism 200 is disposed in the plug 400 of the connector. The socket-side locking mechanism 100 is used to cooperate with the plug-side locking mechanism 200 for locking.

[0047] The socket-side locking mechanism 100 includes:

[0048] A rotating lock 110 is installed on socket 300;

[0049] The plug-side locking mechanism 200 includes:

[0050] The plug latch 210 is elastically connected to the plug 400 via a spring 230, and the plug latch 210 is used to limit the mutual positioning with the socket rotation latch 110.

[0051] The latching cavity 250 is formed by the protrusion on the outer surface of the plug 400 and is located between the plug 400 and the plug latch 210.

[0052] The latching mechanism 240 is disposed within the latching cavity 250 and extends between the plug latch 210 and the plug 400. The latching mechanism 240 is limited by the latching cavity 250 and slides in contact with the plug 400. The latching mechanism 240 is used to limit the plug latch 210.

[0053] Specifically, in this embodiment, the socket rotation latch 110 is annularly disposed on the outer edge of the socket 300, and a latch is provided thereon. The latch locking cavity 250 is formed by the protrusion on the outer surface of the plug 400 and is disposed between the plug 400 and the plug latch 210. The latch locking mechanism 240 is disposed within the latch locking cavity 250 and extends between the plug latch 210 and the plug 400. The latch locking mechanism 240 is limited by the latch locking cavity 250 and slides in contact with the plug 400. (Refer to...) Figure 5 The latching mechanism 240 can slide back and forth within the latching cavity 250. When the latching mechanism 240 is completely within the latching cavity 250, that is, when it is in a latching position... Figure 5 In the state shown on the left, the plug-side locking mechanism 200 is in the locked state, that is, the latching mechanism 240 latches the plug latch 210, preventing the plug latch 210 from being pressed down. This fixes the relative position between the plug latch 210 and the socket rotation latch 110, keeping them mutually locked. Therefore, the connection between the plug 400 and the socket 300 is locked at this time, and the plug 400 and the socket 300 cannot be inserted or separated. When the latching mechanism 240 is not completely within the latching cavity 250, that is, when it is in a locked state... Figure 5 When shown on the right, the plug-side locking mechanism 200 is in the unlocked state, allowing the plug 400 to be inserted into or separated from the socket 300; the latching mechanism 240 is used to limit the plug latch 210.

[0054] When the socket 300 and plug 400 of the connector are to be connected, the latching mechanism 240 is first pulled back to unlock the plug-side locking mechanism 200. Then, the plug 400 is connected to the socket 300. During the connection process, the latching boss of the socket rotation latch 110 causes the plug latch 210 to descend and unlock first. Then, under the elastic force of the spring 230, it is reset and locked, realizing the engagement of the socket rotation latch 110 and the plug latch 210. Finally, the latching mechanism 240 is pushed forward into the latching cavity 250 to limit and lock the plug latch 210, thereby completing the connection between the plug 400 and the socket 300.

[0055] When it is necessary to separate the socket 300 and plug 400 of the already connected connector, first pull out the latching mechanism 240 to unlock the plug-side locking mechanism 200. Then, press the plug latch 210 downward against the spring force of the spring 230 to prevent the plug latch 210 and the socket rotation latch 110 from being mutually restricted and jammed during connection. Then, pull the plug 400 outward to separate the plug 400 from the socket 300. Release the plug latch 210 and push the latching mechanism 240 forward into the latching cavity 250 to limit and lock the plug latch 210, thereby completing the separation of the plug 400 and the socket 300.

[0056] In summary, the latching mechanism 240 is a CPA (connector locking confirmation) structure. Before the plug 400 and the socket 300 are properly mated, the latching mechanism 240 cannot be pushed forward to the locked state. Only after the plug 400 and the socket 300 of the connector are properly mated can the latching mechanism 240 be pushed forward to the locked state. In this locked state, the plug-side locking mechanism 200 cannot be unlocked.

[0057] The double-sided locking structure, which employs a socket-side locking mechanism 100 and a plug-side locking mechanism 200, makes the locking of the plug 400 and socket 300 more reliable, preventing swaying that could cause locking failure. The spring 230 structure allows the plug latch 210 to lock quickly and reset quickly after unlocking. The snap-locking mechanism 240 confirms whether the plug latch 210 and the socket rotary latch 110 are properly engaged, and locks or unlocks the plug latch 210 to prevent accidental locking.

[0058] Reference Figure 3 Furthermore, in some embodiments of this utility model, the socket-side locking mechanism 100 further includes:

[0059] A socket locking limit ring 120 is provided on the socket 300 to limit the socket rotation lock 110 to the outer surface of the socket 300;

[0060] A plug locking ring 220 is provided on the plug 400 to limit the plug latch 210 to the outer surface of the plug 400.

[0061] Specifically, in this embodiment, the socket locking ring 120 is arranged around the outer surface of the socket 300, so that the socket rotation lock 110 cannot disengage from the outer surface of the socket 300 when it can rotate. Two plug locking rings 220 are provided, respectively arranged on the two connecting posts extending upward from the plug 400, and are used to limit the plug lock 210 on the two connecting posts extending upward from the plug 400.

[0062] Reference Figure 2Furthermore, in some embodiments of this utility model, the socket rotary lock 110 includes:

[0063] The rotating ring 111, which adopts a circular strip structure, is located in the socket 300;

[0064] The locking boss 112 is fixedly set on the rotating ring 111 and is used to lock the socket 300 and the plug 400 together with the plug lock 210.

[0065] Specifically, in this embodiment, there are two locking protrusions 112, located on both sides of one diameter of the rotating ring 111. When the connector is docked, the shape of the locking protrusions 112 causes the plug latch 210 to descend under external force, and then return to its original position under the elastic force of the spring 230. At this time, the locking protrusions 112 and the plug latch 210 are structurally riveted together, so that the plug 400 and the socket 300 cannot be separated under external force in the front-back direction.

[0066] Reference Figure 3 and Figure 4 Furthermore, in some embodiments of this utility model, the plug latch 210 includes:

[0067] U-shaped elastic pressing band 211, U-shaped elastic pressing band 211 is elastically connected to plug 400 through spring 230;

[0068] Bottom-touching limit baffle 212 is fixedly installed on the U-shaped elastic pressing belt 211, and the bottom-touching limit baffle 212 is limited by the buckle locking mechanism 240;

[0069] The limiting hook 213 is fixedly set on the U-shaped elastic pressing band 211 and is used to lock the socket 300 and plug 400 together with the locking boss 112.

[0070] Specifically, in this embodiment, two limiting hooks 213 are provided, located on both sides of the U-shaped elastic pressing band 211, corresponding to the locking boss 112. When the connector is docked, the shape of the locking boss 112 causes the limiting hooks 213 to drive the plug locking buckle 210 down, and then reset under the elastic force of the spring 230. At this time, the limiting hooks 213 can hook the locking boss 112 to achieve structural riveting. The bottom-contact limiting baffle 212 and the U-shaped elastic pressing band 211 are integrated into one design. When the plug-side locking mechanism 200 is in the locked state, the bottom-contact limiting baffle 212 is limited by the buckle locking mechanism 240, preventing the U-shaped elastic pressing band 211 from being pressed down. This prevents the locking boss 112 and the limiting barb 213 from being released from their riveting state, thus preventing the plug 400 and the socket 300 from being separated. Alternatively, the locking boss 112 may prevent the U-shaped elastic pressing band 211 from being pressed down, thus preventing the plug 400 and the socket 300 from being connected.

[0071] Reference Figure 3 and Figure 5 Furthermore, in some embodiments of this utility model, the latching mechanism 240 includes:

[0072] The sliding base plate 241 slides in contact with the plug 400, and the sliding base plate 241 is limited by the snap-locking cavity 250;

[0073] The elastic pressing plate 242 is fixedly connected to the sliding base plate 241, and the elastic pressing plate 242 is limited by the snap-locking cavity 250;

[0074] The plug locking limit plate 243 is fixedly connected to the sliding base plate 241, and the plug locking limit plate 243 is used to limit the bottom-touching limit baffle 212.

[0075] Specifically, in this embodiment, the sliding base plate 241 can drive the entire latching mechanism 240 to slide back and forth in the latching cavity; the elastic pressing plate 242 is convenient for applying external force to the latching mechanism 240 and switching the position and state of the latching mechanism 240; the plug latch limiting plate 243 is used to limit the bottom-touching limiting baffle 212, so that the U-shaped elastic pressing band 211 cannot be pressed down; such as Figure 5 As shown, when the latching mechanism 240 is at the front end, the plug latching limit plate 243 limits the bottom-touching limit baffle 212, and the U-shaped elastic pressing band 211 cannot be pressed down. At this time, the plug locking mechanism 100 is in the locked state. When the latching mechanism 240 is pulled back a certain length, the plug latching limit plate 243 releases the limit on the bottom-touching limit baffle 212, and the U-shaped elastic pressing band 211 can be pressed down. At this time, the plug locking mechanism 100 is in the unlocked state.

[0076] Reference Figure 3 Furthermore, in some embodiments of this utility model, the side of the plug latch limiting plate 200 is provided with an unlocking groove 243a, the width of the unlocking groove 243a is greater than or equal to the thickness of the bottom limiting plate 212, and the unlocking groove 243a is used to release the plug latch limiting plate 243 from the bottom limiting baffle 212.

[0077] Specifically, in this embodiment, when the unlocking groove 243a is not aligned with the bottom-touching limiting plate 212, the plug latch limiting plate 243 limits the bottom-touching limiting baffle 212, and the U-shaped elastic pressing band 211 cannot be pressed down. At this time, the plug locking mechanism 100 is in a locked state. When the unlocking groove 243a is aligned with the bottom-touching limiting plate 212, the plug latch limiting plate 243 releases the limit on the bottom-touching limiting baffle 212, and the U-shaped elastic pressing band 211 can be pressed down. At this time, the plug locking mechanism 100 is in an unlocked state.

[0078] Reference Figure 3 Furthermore, in some embodiments of this utility model, the buckle locking cavity 250 is provided with a first limiting through hole 251 and a second limiting through hole 252. The first limiting through hole 251 is used to limit the elastic pressing plate 242, and the second limiting through hole 252 is used to limit the sliding base plate 241.

[0079] Specifically, in this embodiment, the first limiting through hole 251 can prevent the latching mechanism 240 from being accidentally touched by force in the front-back direction, resulting in mis-locking or mis-locking. Only by pressing down the elastic pressing plate 242 to release the limitation of the first limiting through hole 251 can the elastic pressing plate 242 be allowed to drive the sliding base plate 241 to slide back and forth. The second limiting through hole 252 is used to prevent the entire latching mechanism 240 from completely disengaging from the latching locking cavity 250 during the process of the elastic pressing plate 242 driving the sliding base plate 241 to slide backward.

[0080] Reference Figure 3 and Figure 5 Furthermore, in some embodiments of this utility model, the elastic pressing plate 242 is provided with a limiting boss 242a, which is used to cooperate with the first limiting through hole 251 to limit the elastic pressing plate 242.

[0081] Specifically, in this embodiment, only after the elastic pressing plate 242 is pressed down to release the restriction of the first limiting through hole 251 on the limiting boss 242a can the elastic pressing plate 242 be allowed to drive the sliding base plate 241 to slide back and forth; refer to Figure 5 When the limiting boss 242a is inside the first limiting through hole 251, it is in a locked state; when the limiting boss 242a is outside the first limiting through hole 251, it is in an unlocked state.

[0082] Reference Figure 3 Furthermore, in some embodiments of this utility model, the sliding base plate 241 is provided with an extended limiting rod 241a, which is used to limit the sliding base plate 241 in conjunction with the second limiting through hole 252.

[0083] Specifically, in this embodiment, the extended limiting rod 241a can only slide back and forth within the second limiting through hole 252 and cannot disengage from the second limiting through hole 252. This prevents the entire buckle locking mechanism 240 from completely disengaging from the buckle locking cavity 250 during the process of the elastic pressing plate 242 driving the sliding base plate 241 to slide backward, thus maintaining the integration of the plug locking mechanism 200 and preventing the loss of parts.

[0084] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
