Abstract

According to the 12-core straight-head plug and the 12-core straight-head socket, when the plug is connected with the socket, the plug shell and the socket shell are combined and connected in a clamped mode, at the moment, the left front end of the power-assisted rod is connected with the clamping column in a clamped mode, clockwise overturning of the power-assisted rod is limited, meanwhile, the outer edge of the power-assisted rod is connected with the top face of the limiting column, anticlockwise overturning of the power-assisted rod is limited, and the power-assisted rod is prevented from being damaged. The clamping column and the limiting column act at the same time to limit overturning of one end of the power-assisted rod, and under the action of the self-locking mechanism structure, overturning of the other end of the power-assisted rod is limited, so that the plug assembly and the socket assembly are connected more tightly and are not prone to falling off from each other. When the plug assembly and the socket assembly need to be separated, the top surface of the power-assisted rod is pressed by a thumb, the top surface of the power-assisted rod moves downwards under the action of the spring to drive the left front end of the power-assisted rod to be separated from the clamping column, and a guide column and a convex column are arranged in the spring, so that the spring is kept in the annular groove during deformation and is not easy to swing or shake; and the stability of the self-locking mechanism is improved.

Description

Technical Field

[0001] The utility model belongs to the technical field of plugs and sockets, and particularly relates to a 12-core straight plug and socket. Background Art

[0002] As a convenient connecting component, the connector has been widely used in various industries, such as the new energy vehicle industry. Due to different usage environments, there are various requirements for the wire outlet direction of the connector. To improve versatility and reduce input costs, it is usually chosen to share the socket, and the plug has various wire outlet angles. Therefore, the plug has different structural forms such as straight and bent. When the 12-core straight plug and socket are connected and fixed, in order to facilitate the connection between the two, a rotatable assisting rod is often provided on the plug, and the two are tightly connected by controlling the assisting rod and are not easily detached.

[0003] However, when locking the plug and socket through the rotatable assisting rod, the assisting rod often lacks a limiting mechanism and a self-locking mechanism, resulting in the assisting rod shaking under the action of the rotating pin during use, thereby affecting the connection strength between the plug and the socket. Therefore, the utility model proposes a 12-core straight plug and socket to solve the above problems. Summary of the Invention

[0004] The utility model provides a 12-core straight plug and socket, aiming to solve the problems proposed in the background art.

[0005] The utility model is realized as follows: a 12-core straight plug and socket includes a plug assembly and a socket assembly;

[0006] The plug assembly includes a plug housing, an assisting rod, a limiting post and a self-locking mechanism. Two relatively spaced rotating pins are provided on the outer wall of the plug housing. The assisting rod rotates around the rotating pin. A limiting post is provided on the side of the rotating pin close to the socket assembly. The top surface of the limiting post is a flat structure. A ring groove is formed on the outer wall of the plug housing. A convex post is provided on the inner side of the assisting rod. The self-locking mechanism includes a guiding post and a spring. The guiding post is arranged on the bottom surface of the inner wall of the ring groove. One end of the spring is located on the outer wall of the guiding post and is fixedly connected to the bottom surface of the inner wall of the ring groove, and the other end is located on the outer wall of the convex post and is fixedly connected to the assisting rod;

[0007] The socket assembly includes a socket housing. A clamping post is provided on the outer wall of the socket housing. The clamping post is clamped with the assisting rod.

[0008] Preferably, the plug housing is clamped with the socket housing.

[0009] Preferably, the top surface of the guiding post is an inclined surface structure.

[0010] Preferably, the guiding column is coaxial with the convex column, and there is a gap between the two.

[0011] Preferably, the top surface of the limiting column is connected to the outer edge of the assisting rod.

[0012] Preferably, the assisting rod is fixedly connected to the plug housing through the spring.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For the plug and socket of the present utility model, when the plug assembly and the socket assembly are connected, the plug housing and the socket housing are combined and snapped together. At this time, the left front end of the assisting rod is snapped with the engaging column, restricting the clockwise rotation of the assisting rod. At the same time, the outer edge of the assisting rod is connected to the top surface of the limiting column, restricting the counterclockwise rotation of the assisting rod. The engaging column and the limiting column act together to restrict the rotation of one end of the assisting rod, and under the action of the self-locking mechanism structure, the rotation of the other end of the assisting rod is restricted, thereby making the connection between the plug assembly and the socket assembly tighter and not easily falling off from each other.

[0015] 2. For the plug and socket of the present utility model, when it is necessary to separate the plug assembly and the socket assembly, press the top surface of the assisting rod with the thumb. At this time, the top surface of the assisting rod moves downward under the action of the spring, driving the left front end of the assisting rod to disengage from the engaging column. Since the guiding column and the convex column are provided inside the spring, the spring remains inside the annular groove during deformation and is not easily swayed or shaken, increasing the stability of the self-locking mechanism. At the same time, the top surface of the guiding column is a bevel structure, which is convenient for pressing down the top surface of the assisting rod; the top surface of the limiting column is a flat structure, which is convenient for restricting the flipping of the edge of the assisting rod.

A limiting post 13 is provided on the side of the rotating pin 112 close to the socket assembly 2. The top surface of the limiting post 13 is a flat structure. A ring groove 111 is formed on the outer wall of the plug housing 11. A convex post 121 is provided on the inner side of the boosting rod 12. The self-locking mechanism 14 includes a guiding post 141 and a spring 142. The guiding post 141 is provided on the bottom surface of the inner wall of the ring groove 111. One end of the spring 142 is located on the outer wall of the guiding post 141 and is fixedly connected to the bottom surface of the inner wall of the ring groove 111, and the other end is located on the outer wall of the convex post 121 and is fixedly connected to the boosting rod 12; the socket assembly 2 includes a socket housing 21. A clamping post 22 is provided on the outer wall of the socket housing 21. The clamping post 22 is clamped with the boosting rod 12.

[0029] In this embodiment, refer to Figure 1 and Figure 2 , when the plug assembly 1 and the socket assembly 2 are connected, the plug housing 11 and the socket housing 21 are combined and clamped with each other. Refer to Figure 3 , at this time, the left front end of the boosting rod 12 is clamped with the clamping post 22, restricting the clockwise rotation of the boosting rod 12. At the same time, the outer edge of the boosting rod 12 is connected to the top surface of the limiting post 13, restricting the counterclockwise rotation of the boosting rod 12. The clamping post 22 and the limiting post 13 act together to restrict the rotation of one end of the boosting rod 12. And under the action of the structure of the self-locking mechanism 14, the rotation of the other end of the boosting rod 12 is restricted, so that the connection between the plug assembly 1 and the socket assembly 2 is tighter and not easily separated from each other; when it is necessary to separate the plug assembly 1 and the socket assembly 2, press the top surface of the boosting rod 12 with the thumb. At this time, the top surface of the boosting rod 12 moves downward under the action of the spring 142, driving the left front end of the boosting rod 12 to disengage from the clamping post 22. Since the guiding post 141 and the convex post 121 are provided inside the spring 142, the spring 142 is kept inside the ring groove 111 and not easily swings or shakes during deformation, increasing the stability of the self-locking mechanism 14; at the same time, the top surface of the guiding post 141 is a bevel structure to facilitate the downward pressing of the top surface of the boosting rod 12; the top surface of the limiting post 13 is a flat structure to facilitate restricting the edge rotation of the boosting rod 12.

[0030] Further, please refer to Figure 3 , the plug housing 11 is clamped with the socket housing 21.

At this time, the top surface of the assist lever 12 moves downward under the action of the spring 142, driving the left front end of the assist lever 12 to disengage from the engaging post 22. The inclined surface structure of the top surface of the guide post 141 facilitates the downward pressing of the top surface of the assist lever 12.

[0034] Further, please refer to Figure 5 , the guide post 141 is coaxial with the convex post 121, and there is a gap between the two.

[0035] In this embodiment, the guide post 141 is coaxial with the convex post 121, and there is a gap between the two.

[0038] Further, please refer to Figure 1 and Figure 5 , the assist lever 12 is fixedly connected to the plug housing 11 through the spring 142.

[0039] In this embodiment, the assist lever 12 is fixedly connected to the plug housing 11 through the spring 142, facilitating the combination and separation of the plug assembly 1 and the socket assembly 2.
