Description

Technical Field

[0001] The utility model belongs to the technical field of heavy-duty connectors, and in particular relates to an electric connector based on a lock and auxiliary separation integrated structure. Background Art

[0002] The resistance to plugging and unplugging multi-core electrical connectors is very high, and workers usually need to use both hands and cooperate with impacting or shaking the plug to achieve the plugging and unplugging of such electrical connectors; there are even operations where the cable is directly pulled out to pull out the plug. This operation can easily cause fatal damage to the electrical system and the main structure of the electrical connector, and may cause the pins to bend and be damaged or the electrical connection to be disconnected. In addition, at the moment the plug is removed, the influence of inertia can easily cause harm to the human body. In addition, in a small space, due to the limited force applied by the human body, the plugging and unplugging of large electrical connectors can be very difficult. Therefore, it is necessary to design a structure that can assist workers in unplugging the plug, and the modification of the connector itself should be minimized to reduce equipment costs. Summary of the invention

[0003] The utility model aims to provide an electrical connector based on a lock and auxiliary separation integrated structure.

[0004] The utility model provides an electrical connector based on a lock and auxiliary separation integrated structure, which includes a connector body and a lock assembly; the connector body includes a plug and a socket; the lock assembly includes a locking pin and a hook lock structure; the inner ends of two coaxially arranged locking pins are respectively fixed to the two side surfaces of the plug; the hook lock structure includes two locking plates. The two locking plates are rotatably connected to the two side surfaces of the socket respectively. The rotation axes of the two locking plates coincide. The locking plates are each provided with a locking groove that matches the position of the locking pin, and are each connected to an unlocking handle.

[0005] The side wall of the locking groove near the axis of the locking piece extends outward to form a push edge. In the direction from the inner end to the outer end of the push edge, the distance from the push edge to the rotation axis of the locking piece gradually increases. The inner end of the push edge is the end of the push edge connecting to the locking groove; the outer end of the push edge is the end of the push edge connecting to the locking groove.

[0006] When the unlocking handle is turned over in the locked state, the locking groove and the locking pin gradually separate, and the push edge pushes the plug away from the socket, thereby helping the staff to pull the plug out of the socket. In the process of separating the locking groove and the locking pin, the elastic deformation of the locking piece is used to avoid the problem of the locking pin being stuck and unable to unlock and release.

[0007] Preferably, the pushing edge is straight.

[0008] Preferably, the difference between the distances between the outer end and the inner end of the pushing edge and the rotation axis of the locking piece is greater than or equal to the insertion depth of the plug relative to the socket.

[0009] Preferably, a connecting convex edge is provided at the bottom of the side of the socket. The connecting convex edge cooperates with the side edge of the locking piece to define the flipping limit position of the locking piece. When the connecting convex edge is in contact with the locking piece, the outer end of the pushing edge is directly below the locking pin, or close to the side of the locking pin away from the locking groove.

[0010] Preferably, a connection hole for fixing the installation position of the socket is provided on the connection protrusion.

[0011] Preferably, the side wall of the locking groove away from the rotation axis of the locking piece is a locking edge; the locking edge is in an arc shape matching the locking pin. The locking edge can hook the top of the locking pin to form a locking structure; when the locking pin enters the locking groove, the locking edge covers and passes over the highest point of the locking pin.

[0012] Preferably, the opening of the locking groove is provided with an arc-shaped guide edge on one side connected to the locking edge.

[0013] Preferably, the unlocking handle is provided with anti-slip stripes.

[0014] Preferably, two locking pins in the same hook lock structure share the same unlocking handle; two ends of the unlocking handle are fixedly connected to the corresponding two locking pieces respectively.

[0015] Preferably, there are two locking assemblies; the two locking assemblies are symmetrically arranged at both ends of the bottom of the connector body; when the hook lock structure locks the locking pin, the plug is located between the unlocking handles in the two locking assemblies.

[0016] The beneficial effects of the utility model are:

[0017] On the basis of the existing locking structure of the electrical connector, the utility model extends a pushing edge on the locking groove, and sets "the distance from the pushing edge to the rotation axis of the locking piece gradually increases in the direction from the inner end to the outer end of the pushing edge", thereby enabling the utility model to use the pushing edge to push the locking pin upward when flipping the locking structure, thereby assisting in completing the plug removal action; thereby reducing the damage to the connector that may be caused when the worker pulls out the plug.

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, an electrical connector based on a lock and auxiliary separation integrated structure includes a connector body 1 and a lock assembly 2. The connector body 1 includes a plug 1-1 and a socket 1-2. Figure 3 As shown, in the initial state, the bottom end of the plug 1-1 is plugged into the socket 1-2, and the pin at the bottom of the plug 1-1 passes through the socket 1-2. A connecting flange 1-3 is provided at the bottom of the side of the socket 1-2. A connecting hole for fixing the installation position of the socket 1-2 is provided on the connecting flange 1-3.

[0025] like Figure 1 and 2 As shown, two locking components 2 are symmetrically arranged at the two ends of the bottom of the connector body 1, which are used to define the relative positions of the plug 1-1 and the socket 1-2 in the connector body 1, and to separate the auxiliary plug 1-1 from the socket 1-2. The locking component 2 includes a locking pin 2-1 and a hook lock structure; the inner ends of the two coaxially arranged locking pins 2-1 are respectively fixed to the two side surfaces of the plug 1-1; the hook lock structure includes an unlocking handle 2-2 and two locking pieces 2-3. The locking piece 2-3 is made of plastic. The two locking pieces 2-3 are respectively connected to the two side surfaces of the socket 1-2. The rotation axes of the two locking pieces 2-3 coincide. When the push edge 2-4 is turned outward, the force applied by the push edge 2-4 to the locking pin 2-1 has an upward component, so that the locking pin 2-1 is lifted upward. Driven by the locking pin 2-1, the plug 1-1 is separated from the socket 1-2. The side edge of the locking piece 2-3 cooperates with the connecting convex edge 1-3, so that the locking piece 2-3 stops when the side edge contacts the connecting convex edge 1-3 during the outward turning process, thereby limiting the turning limit position of the locking piece 2-3. The outer ends of the locking piece 2-3 are both connected to the unlocking handle 2-2. The unlocking handle 2-2 is provided with anti-slip stripes, which are serrated and can increase the friction between the fingers of the staff and the unlocking handle 2-2.

[0026] The inner ends of the locking pieces 2-3 are provided with locking grooves that match the positions of the locking pins 2-1. The side walls of the locking grooves close to the axis of the locking pieces 2-3 extend outward to form a linear push edge 2-4. The inner end of the push edge 2-4 is the end of the push edge 2-4 connected to the locking groove; the outer end of the push edge 2-4 is the end of the push edge 2-4 connected to the locking groove. In the direction from the inner end to the outer end of the push edge 2-4, the distance from the push edge 2-4 to the rotation axis of the locking piece 2-3 gradually increases. Among them, the difference between the distances from the outer end and the inner end of the push edge 2-4 to the rotation axis of the locking piece 2-3 is greater than or equal to the insertion depth of the plug 1-1 relative to the socket 1-2, so that when the locking piece 2-3 is flipped outward to the extreme position, the outer end of the push edge 2-4 is directly below the locking pin 2-1, or close to the side of the locking pin 2-1 away from the locking groove, so that it is convenient for the staff to take the plug 1-1.

[0027] The side wall of the locking groove away from the rotation axis of the locking piece 2-3 is the locking edge 2-5; the locking edge 2-5 is in an arc shape that matches the locking pin 2-1. The locking edge 2-5 can hook the top of the locking pin 2-1 to form a locking structure; when the locking pin 2-1 enters the locking groove, the locking edge 2-5 covers and passes over the highest point of the locking pin 2-1. The opening of the locking groove is provided with an arc-shaped guide edge on one side connected to the locking edge 2-5, which is used to guide the locking pin 2-1 during the flipping process of the locking piece 2-3, so that the locking pin 2-1 can smoothly enter the locking groove.

[0028] During operation, the connector has two working states, namely, a plug-in state and a disconnected state. When the connector is in the plug-in state, the plug 1-1 is plugged into the socket 1-2. The locking pieces 2-3 on both sides of the socket 1-2 are flipped inward, and the plug 1-1 is located between the unlocking handles 2-2 in the two locking components 2. At the same time, the locking pin 2-1 enters the locking groove, and the locking edge 2-5 covers and passes over the highest point of the locking pin 2-1. Thus, the relative position of the plug 1-1 and the socket 1-2 is locked. When the connector is in the locked state, the distance between the arc center of the locking edge 2-5 and the rotation axis of the locking piece 2-3 is R1. Among them, the distance between the pushing edge 2-4 and the rotation axis of the locking piece 2-3 is R2. When the plug 1-1 is inserted into the socket 1-2 to the extreme position, the distance between the locking pin 2-1 on the plug 1-1 and the rotation axis of the locking piece 2-3 is R3, and R2≤R3≤R1, so that the locking pin 2-1 can smoothly enter the locking groove.

[0029] When the connector is in the separated state, the locking edge 2-5 releases the highest part of the locking pin 2-1. The outer end of the pushing edge 2-4 is directly below the locking pin 2-1, or close to the side of the locking pin 2-1 away from the locking groove. The plug 1-1 is separated from the socket 1-2. Figure 4As shown, the staff applies downward pressure to the unlocking handle 2-2 to switch the connector from the plugged state to the separated state. In the process of the staff applying pressure to the unlocking handle 2-2, the locking piece 2-3 is driven to flip outward. In the process of flipping the locking piece 2-3, the locking edge 2-5 gradually releases the coverage of the highest point of the locking pin 2-1. At the same time, the pushing edge 2-4 on the locking piece 2-3 pushes the corresponding locking pin 2-1 on the plug 1-1 to move away from the socket 1-2, thereby helping the staff to pull the plug 1-1 out of the socket 1-2. In the process of separating the locking groove from the locking pin 2-1, the elastic deformation of the locking piece 2-3 is used to avoid the problem that the locking pin 2-1 is stuck and cannot be unlocked and released.
