DETAILED DESCRIPTION

[0041] The present application is described below based on the following embodiments, but the present application is not limited to these embodiments. In the detailed description of the present application below, certain specific details are described in detail. Those skilled in the art can fully understand the present application without the description of these details. To avoid obscuring the essence of the present application, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] Furthermore, persons of ordinary skill in the art will appreciate that the figures provided herein are for illustration purposes only and are not necessarily drawn to scale.

[0043] Unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," and the like should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0044] For ease of explanation, spatially relative terms such as "in," "out," "under," "below," "lower," "above," "upper," and the like are used herein to describe the relationship of one element or feature illustrated in the figures to another element or feature. It will be understood that spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

[0045] Unless the context clearly requires otherwise, words like “include”, “comprising” and the like throughout this application should be interpreted as including rather than exclusive or exhaustive; that is, as meaning “including but not limited to”.

[0046] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance. In addition, in the description of this application, unless otherwise specified, "plurality" means two or more.

[0047] Figure 1 This is a schematic diagram of the structure of the connector provided by the embodiment of the utility model. Figure 2 This is a structural diagram of another perspective of the connector provided by the embodiment of the utility model, combined with Figure 1 and Figure 2 As shown, the joint A includes a joint body 1 and a rotating member 2 . Figure 3 This is a schematic diagram of the structure of the connector body provided by the embodiment of the present invention. Figure 3 As shown, the connector body 1 is provided with an assembly hole 11 and two engaging rods 12. Specifically, the engaging rods 12 are configured to swing between an engaged position and an unengaged position. It should be noted that when the engaging rods 12 are in the engaged position, the two engaging rods 12 are in an initial state and parallel to each other. Correspondingly, when the engaging rods 12 are in the unengaged position, the two engaging rods 12 deflect toward each other. Figure 4 This is a schematic diagram of the structure of the connector provided by the embodiment of the utility model after docking with the mating connector. Figure 5 This is a schematic diagram of the structure of the matching connector provided by the embodiment of the utility model, combined with Figures 1 to 5As shown, when connector A is mated with mating connector B, the two fastening rods 12 are in the fastening position, thereby fastening the two buckle bodies B1 on the mating connector B. On the other hand, when the fastening rods 12 are in the unfastening position, they are separated from the corresponding buckle bodies B1. It should be noted that the separation of the fastening rods 12 from the buckle bodies B1 means that the fastening rods 12 can move relative to the buckle bodies B1 in the direction of insertion of connector A.

[0048] Figure 6 This is a schematic diagram of the structure of the rotating member provided by the embodiment of the utility model. Figure 6 As shown, the rotating member 2 has a pressing portion 21 . Figure 7 This is a schematic diagram of the position of the connector and the mating connector provided by the embodiment of the utility model before docking. Figure 8 This is a cross-sectional diagram of the connector provided by the embodiment of the present invention and the mating connector before docking. Figure 9 This is a cross-sectional view of the connector provided by the embodiment of the present invention and the mating connector after docking. Figure 10 This is a schematic diagram of the position of the rotating member provided by the embodiment of the utility model when it is in the locked position. Figure 11 This is a cross-sectional diagram of the rotating member provided by the embodiment of the present invention when it is in the locked position, combined with Figures 7 to 11 As shown, the rotating member 2 is rotatably arranged in the assembly hole 11 and is configured to rotate between a locked position and an unlocked position. Furthermore, the pressing portion 21 is located between the two buckling rods 12. Furthermore, when the rotating member 2 rotates to the locked position, it drives the pressing portion 21 to rotate into position so as to synchronously press the two buckling rods 12. On the other hand, when the rotating member 2 rotates to the unlocked position, it drives the pressing portion 21 to rotate into position so as to synchronously disengage the two buckling rods 12. It is easy to understand that when the two buckling rods 12 are buckled with the two buckle bodies B1, the two ends of the pressing portion 21 act on the two buckling rods 12 synchronously. In other words, even if the two buckling rods 12 tend to deflect toward the unlocked position, they will interact with each other while being subjected to the force of the pressing portion 21, so that the entire locking structure is self-locking, thereby helping to improve the reliability of the connection when the connector A is docked with the mating connector B. On the other hand, when connector A does not need to be docked with the mating connector B, the rotating part 2 rotates to cause the pressing part 21 to synchronously press the two fastening rods 12, so that the fastening rods 12 cannot be deflected to the unfastening position, and cannot be fastened with the buckle body B1, thereby preventing connector A and the mating connector B from being inserted into place.

[0049] As an optional embodiment, there is only one fastening rod 12. That is, the reliability of the connection between the connector A and the mating connector B can be ensured by the rotation member 2 cooperating with one fastening rod 12 and one buckle body B1.

[0050] like Figure 6As shown, in one embodiment, the rotating part 2 further includes a main body 22 and a driving part 23. Specifically, the main body 22 matches the assembly hole 11 and is rotatably arranged in the assembly hole 11, and the pressing part 21 is arranged at one end of the main body 22 facing the buckle rod 12. It should be noted that, corresponding to the assembly hole 11 being set as a circular hole, the main body 22 is set as a cylindrical structure as a whole, thereby facilitating the rotation of the rotating part 2 in the assembly hole 11. Furthermore, the driving part 23 is arranged at one end of the main body 22 away from the pressing part 21. It is easy to understand that when the operator rotates the driving part 23, the pressing part 21 can be driven to rotate through the main body 22, so that the pressing part 21 presses or disengages the buckle rod 12.

[0051] Figure 12 This is a partially enlarged schematic diagram of the assembly hole provided by the embodiment of the utility model, such as Figure 12 As shown, in one embodiment, an annular boss 111 is provided on the inner side wall of the assembly hole 11. Correspondingly, Figure 13 This is a cross-sectional diagram of the rotating member provided by the embodiment of the present invention when it is in the unlocked position, combined with Figure 6 、 Figure 12 and Figure 13 As shown, an annular groove 221 is provided on the side of the main body 22, and the annular groove 221 matches the annular boss 111 to accommodate the annular boss 111. It is easy to understand that the annular boss 111 is located within the annular groove 221, thereby enabling the rotation member 2 to be installed in the assembly hole 11. Furthermore, when the rotation member 2 rotates between the locked position and the unlocked position, the annular boss 111 moves relative to the annular groove 221.

[0052] like Figure 6 As shown, in one embodiment, the annular groove 221 is arranged at 330 degrees to form the first gap 222. On the other hand, as Figure 12 As shown, the annular boss 111 is arranged at 240° to form the second gap 112. It is easy to understand that when the rotating member 2 rotates between the locked position and the unlocked position, the annular boss 111 has a 90° range of motion when moving within the annular groove 221. In other words, the rotating member 2 can reach the unlocked position by rotating 90° from the locked position. Correspondingly, the rotating member 2 can reach the locked position by rotating 90° from the unlocked position. Thus, the pressing portion 21 can ensure complete disengagement from the buckle rod 12 or effectively press the buckle rod 12 through a 90° rotation.

[0053] like Figure 6As shown, in one embodiment, the main body 22 is formed with a stopper 223 at the first gap 222. It is easy to understand that the first gap 222, i.e., the stopper 223, is arranged at a 30° angle. Correspondingly, the second gap 112 is arranged at a 120° angle. Furthermore, the stopper 223 moves within the second gap 112. Thus, when the rotating member 2 rotates to the locked position or the unlocked position, the stopper 223 abuts against the end of the annular boss 111, thereby ensuring that the rotating member 2 rotates to the correct position and limiting the rotation of the rotating member 2.

[0054] like Figure 12 As shown, in one embodiment, an arc-shaped boss 113 is arched at the middle position of the second gap 112. Furthermore, the arc-shaped boss 113 is arranged at 60 degrees. It is easy to understand that when the rotating member 2 is in the locked position or the unlocked position, the stopper 223 does not contact the arc-shaped boss 113, and the arc-shaped boss 113 can play a certain limiting role on the stopper 223 so that the position of the rotating member 2 can remain fixed. It should be noted that the degree of arching of the arc-shaped boss 113 is relatively small. Therefore, when the rotating member 2 rotates from the locked position to the unlocked position, or from the unlocked position to the locked position, the stopper 223 will press the arc-shaped boss 113 to rotate, so that the resistance caused by the arc-shaped boss 113 to the rotating member 2 can be fed back to the operator, so as to provide the operator with a feedback feel of rotation.

[0055] like Figure 12 As shown, in one embodiment, a first slope 1131 is provided at each end of the arc-shaped boss 113. Thus, when the rotating member 2 rotates from the locked position to the unlocked position, or vice versa, the stopper 223 can slide along the first slope 1131 onto the arc-shaped boss 113, thereby reducing the resistance of the rotating member 2 during rotation.

[0056] like Figure 12 As shown, in one embodiment, both sides of the arc-shaped boss 113 are respectively formed into a second slope 1132. Therefore, when the rotating member 2 rotates and the stopper 223 slides on the arc-shaped boss 113, the contact area between the stopper 223 and the arc-shaped boss 113 is small, which helps to improve the smoothness of the rotation of the rotating member 2.

[0057] like Figure 12 As shown, in one embodiment, a first inclined surface 1111 is formed on the annular boss 111. Correspondingly, a second inclined surface 2211 is formed in the annular groove 221. It is easy to understand that the second inclined surface 2211 matches the first inclined surface 1111. Thus, the inclined contact between the annular boss 111 and the annular groove 221 helps improve the smoothness of rotation of the rotating member 2.

[0058] like Figure 6 As shown, in one embodiment, both the driving portion 23 and the pressing portion 21 are configured as rod-shaped structures. On the one hand, the rod-shaped driving portion 23 allows the operator to easily and conveniently twist and rotate the rotating member 2. On the other hand, the rod-shaped pressing portion 21 facilitates the simultaneous pressing or releasing of the engaging rod 12. Furthermore, the driving portion 23 and the pressing portion 21 are arranged parallel to each other. Thus, when the operator rotates the rotating member 2 via the driving portion 23, they can intuitively understand the current position of the pressing portion 21.

[0059] like Figure 6 As shown, in one embodiment, the rotating member 2 further includes a connecting portion 24. Specifically, the connecting portion 24 is connected to the main body 22 and the pressing portion 21. It should be noted that the rotating member 2 can adjust the distance between the pressing portion 21 and the main body 22 through the connecting portion 24, thereby ensuring that the pressing portion 21 and the buckle rod 12 remain in the same plane, thereby ensuring that the pressing portion 21 can press the buckle rod 12.

[0060] Combine Figure 8 、 Figure 9 and Figure 11 As shown, in one embodiment, the locking rod 12 includes a fulcrum portion 121, a rod body portion 122, and a locking portion 123. Specifically, the fulcrum portion 121 protrudes from a predetermined position of the joint body 1. Furthermore, the rod body portion 122 is configured as a rod-shaped structure and is connected to the fulcrum portion 121. It should be noted that the rod body portion 122 is divided into a first rod body 1221 and a second rod body 1222 by the fulcrum portion 121. Furthermore, the locking portion 123 is provided at the end of the first rod body 1221 and is configured to lock with the buckle body B1. Thus, the rod body portion 122 can form a lever structure based on the fulcrum portion 121, thereby enabling swinging between a locking position and an unlocking position. Optionally, the locking rod 12 has sufficient toughness at the position of the fulcrum portion 121. It should be noted that the locking portion 123 protrudes from the first rod body 1221 in a direction away from the pressing portion 21.

[0061] Combine Figure 8 、 Figure 9 and Figure 11As shown, in one embodiment, the length of the first rod 1221 is greater than that of the second rod 1222. Thus, when the end of the first rod 1221 is subjected to a force from the buckle body B1, causing the engaging rod 12 to deflect, the engaging rod 12 only needs to be subjected to a relatively small force to swing to the unfastened position for subsequent engagement with the buckle body B1. Furthermore, when an operator applies force to the second rod 1222, causing the engaging rod to deflect, the force applied by the operator to the engaging rod 12 must be sufficiently large, thereby helping to prevent the engaging rod 12 from easily separating from the buckle body B1 and, in turn, ensuring the reliability of the connection between the connector A and the mating connector B. Optionally, the length of the first rod 1221 is twice that of the second rod 1222.

[0062] Combine Figure 9 and Figure 11 As shown, in one embodiment, the end of the fastening portion 123 facing the mating connector B is provided with a third slope 1231. Therefore, during the mating process between the connector A and the mating connector B, the third slope 1231 of the fastening portion 123 first contacts the buckle body B1, thereby allowing the fastening portion 123 to deflect under the force of the buckle body B1 and drive the fastening rod 12 to deflect toward the unfastening position, thereby achieving automatic fastening of the fastening rod 12 and the buckle body B1.

[0063] Combine Figure 9 and Figure 11 As shown, in one embodiment, the end of the first rod 1221 is provided with a chamfer 12211. It should be noted that the chamfer 12211 can not only prevent collision damage between the buckle rod 12 and the buckle body B1, but also guide the deflection of the buckle rod 12.

[0064] Combine Figure 9 and Figure 11 As shown, in one embodiment, the end of the second rod 1222 is formed with a raised portion 12221. It should be noted that when the operator opens the locking lever 12, they need to apply force to the second rod 1222 to deflect the locking lever 12. The raised portion 12221 can serve as a force point for the locking lever 12 to ensure smooth operation. Furthermore, the raised portion 12221 can also serve as a stop.

[0065] Combine Figure 1 and Figure 3As shown, in one embodiment, a docking groove 13 is formed on one side of the connector body 1 facing the mating connector B. It should be noted that the docking groove 13 matches the mating connector B so that the connector A can be adapted to dock with the mating connector B. Furthermore, the side wall of the docking groove 13 is offset outward to form an expansion groove 131. It should be noted that the expansion groove 131 is used to accommodate the snap-fit ​​rod 12. It is easy to understand that the pressing portion 21 extends into the expansion groove 131. As a result, the structure of the connector A is more compact, the pressing portion 21 and the snap-fit ​​rod 12 do not occupy additional external space, and the assembly of the connector A and the mating connector B is also more secure.

[0066] like Figure 2 As shown, in one embodiment, the bottom of the expansion slot 131 is hollowed out to form a leak hole 132. As a result, the locking rod 12 can be exposed through the leak hole 132. As a result, the operator can easily apply force to the locking rod 12 through the leak hole 132 to open the locking rod 12.

[0067] like Figure 2 As shown, in one embodiment, a notch 133 is formed at the leak hole 132. It is easy to understand that the notch 133 can provide a larger operating space for the operator, so that the operator can more conveniently apply force to the buckle rod 12 through tools or other means.

[0068] An embodiment of the present invention also provides a connector assembly, which includes a connector A and a mating connector B. For example, connector A is a plug and mating connector B is a socket. The structure of connector A is as described above and will not be repeated here. On the other hand, two buckle bodies B1 are formed on the protrusion of mating connector B. Furthermore, when mating connector B is docked with connector A, the two buckle bodies B1 are engaged with two buckling rods 12. Thus, connector A synchronously locks the two buckling rods 12 through the rotating member, which not only helps to improve the reliability of the connection with the mating connector B when connector A is docked, but also can lock the buckling rod 12 when connector A is not docked to prevent connector A from docking incorrectly.

[0069] like Figure 5 As shown, in one embodiment, a fourth slope B11 is provided on one end of the buckle body B1 facing the connector A. Thus, when the connector A is mated with the mating connector B, the buckling portion 123 of the buckling rod 12 can move along the fourth slope B11 to cause the buckling rod 12 to deflect.

[0070] The present invention provides a connector and a connector assembly, the connector including a connector body and a rotating member. The connector body is provided with an assembly hole, a snap-on rod, and a docking slot. The sidewall of the docking slot is offset outward to form an expansion slot to accommodate the snap-on rod. The snap-on rod swings to a snap-on position when the connector is docked with a mating connector to snap onto a buckle body on the mating connector. The snap-on rod separates from the buckle body when it swings to an unlocked position. The rotating member is rotatably disposed within the assembly hole and has a pressing portion. The pressing portion presses the snap-on rod when the rotating member rotates to a locked position. The pressing portion simultaneously disengages the snap-on rod when the rotating member rotates to an unlocked position. Thus, by providing the docking slot and the expansion slot, the connector becomes more compact and avoids occupying external space.

[0071] The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application are intended to be within the scope of protection of the present application.
