Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and in particular relates to a motion docking self-locking mechanism capable of changing the direction of force and carrying loads. Background Art

[0002] At present, the high-voltage connectors of new energy vehicles on the market all include a high-voltage plug and a high-voltage socket, and the electrical connection of the two cables is achieved by plugging and unplugging the high-voltage plug and the high-voltage socket.

[0003] Due to the safety requirements of new energy vehicles for high-voltage connectors, the insertion and removal depth between high-voltage plugs and high-voltage sockets is generally deep. It is difficult to directly insert and remove the high-voltage plug and the high-voltage socket by hand, and it is difficult to completely plug the two together, which is prone to poor contact problems. In addition, manual direct docking is laborious and it is impossible to judge whether the docking is in place. After docking, self-locking is often achieved by the spring force in the connector. With frequent use, the spring force gradually decreases, and there is a risk of self-locking failure. When docking with load (with load), it is impossible to ensure that the plug-in position of the high-voltage plug and the high-voltage socket is stable and accurately docked.

[0004] At present, some high-voltage connectors use handles and limit posts provided on high-voltage plugs and sockets to assist in the insertion and removal of high-voltage plugs and high-voltage sockets. Such high-voltage connectors are called handle-type high-voltage connectors. The working method of the handle-type high-voltage connector is to achieve the locking or separation between the high-voltage plug and the high-voltage socket by rotating the handle component in a clockwise or counterclockwise direction. In a common mechanical structure, the handle component is, for example, assembled on one side of the high-voltage plug or socket in a pivotal manner, and the arc-shaped locking groove on the handle component is matched with the limit post provided on the other side of the high-voltage plug or socket. When the operator rotates the handle component, the limit post slides along the arc-shaped locking groove to achieve the locking and separation of the high-voltage connector. However, the handle and limit post in the above-mentioned method are directly provided on the socket and plug, which causes the socket and plug to become larger in size and complex in structure. In addition, due to the provision of the handle and limit post, the socket and plug can generally only achieve one-to-one plug-in of the corresponding model, which is not universally applicable. Summary of the Invention

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0032] Example

[0033] like Figure 1-9 As shown, a motion docking self-locking mechanism that can change the direction of force and carry load shown in this embodiment includes a shell 1 and a plug 2 provided on the shell 1. A mounting groove 10 is concavely provided on one surface of the shell 1. The plug 2 is provided at the rear end of the mounting groove 10. A motion carrier 3 is slidably provided at the front end of the mounting groove 10 for locking the socket in the outside that is plugged with the plug 2, so that the socket in the outside that is plugged with the plug 2 is locked and fixed by the motion carrier. A handle 4 for driving the motion carrier 3 to move closer to or away from the plug 2 is also rotatably provided on the shell 1, so that the rotation of the handle drives the motion carrier to move back and forth in the mounting groove, and the motion carrier The socket on 3 is docked with or separated from the plug 2; in the above structure, a handle and a motion carrier for locking the external socket are provided on the housing for fixing the plug, so that the socket and the plug can be accurately docked, locked or separated by the external handle and the handle-driven motion carrier, increasing the handle torque, making the docking of the plug and the socket easier, and also reducing the need for additional locking structures on the socket and the plug, reducing the volume of the plug and the socket and simplifying the structure of the two. The structure of the present invention is applicable to the docking and locking of most plugs and sockets, has the characteristics of wide applicability, simple structure, easy installation, and convenient removal of the socket.

[0034] Specifically, a rotating shaft 5 is rotatably provided on both sides of the mounting groove 10, and an axial hole 41 is penetrated on both sides of the handle 4 and is respectively connected to the rotating shaft 5 on both sides of the mounting groove 10, and the axial hole is a square hole, which realizes the fixation and synchronous rotation of the axial hole and the rotating shaft, and an elastic retaining ring 51 located on the inner side of the handle 4 is provided on the rotating shaft 5. After one end of the rotating shaft is fitted into the axial hole, the elastic retaining ring is used to fix the two to avoid the problem of loosening; the rear end of the moving carrier 3 is slidably connected to the front end of the handle 4, thereby driving the moving carrier to move forward and backward during the rotation of the handle.

[0035] In this embodiment, an arc-shaped hole 42 is provided on both sides of the handle 4, and a boss 31 is provided on the upper ends of the two outer sides of the moving carrier 3, which is slidably sleeved in the arc-shaped hole 42. The arc length of the arc-shaped hole is the sliding stroke of the boss in the arc-shaped hole when the handle is rotated 90 degrees. In this way, after the handle is rotated 90 degrees, it indicates that the socket and the plug are docked in place; specifically, in the initial state, the handle 4 is vertically arranged above the plug 2, that is, the handle and the shell are perpendicular to each other, and the boss 31 is located at one end of the arc-shaped hole 42, and the other end of the arc-shaped hole 42 is located vertically with the rotation axis. On the line, and after the handle 4 is rotated downward 90 degrees to dock and lock the socket and plug on the moving carrier, the boss 31 is located at the other end of the arc hole. At this time, the boss and the rotation axis are just on the same straight line. When the socket is subjected to an outward reaction force (loaded gravity), the force point of the reaction force is the boss, and the force is applied to the handle through the boss. However, because the boss and the rotation axis are just on the same straight line and the direction of force is the same, dead point self-locking is achieved, avoiding the problem of separation of the two due to the loaded gravity when the socket (with load) is docked with the plug.

[0036] Specifically, a guide groove 101 is recessed in the middle of the bottom of the installation groove 10 along the sliding direction of the moving carrier 3, and a guide bar 32 is provided on the bottom protrusion of the moving carrier 3 and is placed in the guide groove 101, so that the guide groove and the guide bar are used to guide the forward and backward movement of the moving carrier, thereby avoiding the problem that the moving carrier deflects left and right, resulting in the socket and plug on it cannot be accurately docked; in addition, a limit groove 102 is provided at the bottom of both sides of the installation groove 10, and the outer protrusions at both ends of the moving carrier 3 are provided with a limit bar 33 located in the limit groove 102, thereby using the limit groove to limit the moving carrier, firstly, to avoid the problem of the moving carrier deflecting up and down, and secondly, to confine the moving carrier in the installation groove 10 to avoid the problem of accidental separation between it and the shell; in practice, the length of the guide groove is equal to the sum of the length of the guide bar and the stroke of the moving carrier moving forward and backward, so that after the socket and the plug are docked and locked, the guide groove is used to stop the moving carrier to avoid the problem that the handle continues to be pressed down, resulting in excessive force on the boss and damage.

[0037] Specifically, both sides of the front end of the moving carrier 3 are convexly provided with an elastic buckle 34 for locking the socket, and the socket 20 (such as Figure 10 As shown), a raised limiting column 35 is provided on both inner sides of the rear end of the moving carrier 3, and the limiting columns are engaged with the corresponding positions on both sides of the socket, thereby cooperating with the elastic snap buckle to transmit the force of the moving carrier moving forward and backward to the socket, so that the socket and the moving carrier move synchronously, and the two elastic snap buckles 34 and the two limiting columns 35 are symmetrically arranged on the left and right.

[0038] Specifically, the motion carrier 3 includes a left motion carrier 301 and a right motion carrier 302. One side of the left motion carrier 301 is provided with a guide bar 32 that is bent downward to form a step shape and is located in the guide groove 101. One side end of the right motion carrier 302 is located at the step above the guide bar 32 and the two are fixed with screws, so that the right motion carrier 302 is used to fill the step and realize the docking and fixation of the left motion carrier 301 and the right motion carrier 302, so that the surfaces of the left motion carrier and the right motion carrier are flush; the elastic buckles, limit columns and limit bars on both sides are respectively arranged on the left motion carrier 301 and the right motion carrier 302; the motion carrier 3 is divided into two parts, the left motion carrier 301 and the right motion carrier 302, to facilitate the installation of the motion carrier in the installation groove and facilitate the connection with the handle.

[0039] In this embodiment, the shell 1 includes a lower shell 11 and an upper shell 12 covering the lower shell 11. The mounting groove 10 is provided on the surface of the lower shell 11. The upper shell 12 is provided with an opening at a position corresponding to the mounting groove 10, thereby exposing the mounting groove. The handle 4 is rotated on the inner side of the opening through the rotating shaft 5, that is, the handle is provided on the upper shell 12, and a limiting groove 102 is formed between the upper shell 12 and the bottom of the mounting groove 10.

[0040] In this embodiment, the rear end of the plug 2 is fixed to the lower housing 11 by screws.

[0041] In this embodiment, a clamping slot 103 for clamping and fixing a cable is provided at the front end of the housing 1 at a position corresponding to the mounting slot 10 .

[0042] In this embodiment, a stop step 121 is provided on the inner side of the opening of the upper shell 12 to stop the handle from rotating downward, so that the handle can only rotate downward 90 degrees, avoiding the problem of the boss being damaged by pressure due to excessive rotation of the handle.
