The principle of the invention is as follows:
The electric plug is provided with a plug buckle, and the electric plug can be connected with the electric socket in a buckle mode, so that the electric plug is tightly connected with the electric socket. Through the design of the elastic piece, a user can force the plug buckle to move to one side far away from the buckling block, so that the plug buckle is separated from the plug buckling hole, and the electric plug is pulled out. Meanwhile, based on the design of the elastic piece, after the electric plug is pulled out of the electric socket, the plug buckle is reset under the action of the elastic piece, and the electric socket is simple and convenient to use.
In order to facilitate the user to press the plug buckle, the electric plug can be provided with a guide hole for guiding the moving direction of the plug buckle, the opening of the guide hole faces the outer side of the electric plug, and the elastic piece is arranged in the guide hole and is abutted with the plug buckle; the plug buckle is placed in the guide hole, and the buckling block reciprocates in the guide hole along the elastic direction of the elastic piece. Therefore, whether the user forces the plug buckle to move to one side away from the buckling block or the plug buckle resets under the action of the elastic piece, the buckling block always moves in the guide hole, so that the position deviation of the buckling block is avoided, and the user is ensured to smoothly press the plug buckle. Secondly, the plug fastener can extend to the outer side of the guide hole to form a pressing part, and an extrusion surface perpendicular to the elastic direction of the elastic piece is arranged on the pressing part and is a plane, so that a user can press the plug fastener.
In order to facilitate the buckling of the plug into the plug buckling hole, the buckling block can be provided with a guide inclined plane for guiding the buckling body to buckle into the plug buckling hole; the guide inclined plane is positioned on one side of the buckling block away from the electric plug, and an included angle with the plug buckling hole is formed.
In order to ensure the use safety of the plug and socket structure, the electric plug is also provided with a ground wire pin communicated with the ground wire, a plurality of electric jacks and at least one grounding jack are arranged in the electric socket, the electric jacks and the grounding jacks are both provided with openings on the same end face of the base body, and the electric wire female terminal is arranged in the electric jacks; the grounding jack is arranged close to the periphery of the seat body, and a mounting opening is formed at one end of the grounding jack, facing the outer side of the seat body, of the periphery of the grounding jack; the installation opening is internally provided with a ground wire clamping block which can elastically recover towards the inside of the ground jack and is used for being communicated with the ground wire pin, and the ground wire clamping block extends to the outer side of the seat body through the installation opening to form an elastic sheet block which is elastically connected with the ground wire clamping block. The circumference measurement of the seat body refers to the circumferential side surface of the seat body, which surrounds the end surface of the seat body provided with the opening. The circumferential measurement of the ground jack described above refers to the circumferential side around the opening of the ground jack.
After the electric socket is arranged in the bus duct, the electric plug is inserted into the electric socket, so that the ground wire pins are inserted into the grounding jacks, the ground wire pins can extrude the ground wire clamping blocks, the ground wire clamping blocks swing in the direction away from the grounding jacks through the mounting openings, the spring plate blocks move towards the inner wall of the bus duct and are finally attached to the inner wall of the bus duct, the circuit is grounded in the bus duct, and the circuit leakage is prevented. Meanwhile, as the ground wire clamping block can elastically recover towards the inside of the grounding jack, the ground wire clamping block can continuously exert acting force on the ground wire pins, and the tight connection between the ground wire pins and the ground wire clamping block is ensured. When the electric plug is pulled out of the electric socket, the ground wire clamping block can move towards the inside of the grounding jack under the elastic action of the ground wire clamping block after the ground wire clamping block loses the extrusion of the ground wire pins to the ground wire clamping block, and the ground wire clamping block is restored to the original state. In addition, the ground pins may have a height higher than the height of the wire pins. Thus, when the electric plug is plugged into or pulled out of the electric socket, the ground wire pins and the electric socket are always connected with the electric socket earlier (plugged in)/later (pulled out) than the electric wire pins, so that the electric plug is always grounded in the power-on process.
In order to ensure the elasticity of the ground wire clamping block, the base body can be provided with a swinging base block positioned in the installation opening, and the swinging base block extends to the bottom of the base body to form a clamping block; the ground wire clamping block is provided with a swinging through hole matched with the swinging base block at one end farthest from the connection position of the ground wire clamping block and the elastic sheet block, and the swinging base block penetrates into the swinging through hole; the elastic piece extends to one side of the swing base block, and a buckling block is arranged at one end of the elastic piece furthest from the connection position of the ground wire clamping block and the elastic piece, and the buckling block are buckled with each other. In addition, the limit stop can be arranged in the installation opening so as to limit the swing amplitude of the ground wire clamping block and prevent the ground wire clamping block from falling off, and a clearance hole can be formed in the position, corresponding to the limit stop, on the elastic piece block, so that the elastic piece block is not blocked by the limit stop.
In order to ensure the tight connection between the ground wire pins and the ground wire clamping blocks, the ground wire clamping blocks can comprise a body part, a connecting part and a clamping part, wherein one end of the body part is elastically connected with the elastic sheet block, and the other end of the body part is connected with the connecting part; one end of the connecting part is connected with the body part, and the other end is connected with the clamping part; the buckling part and the body part are staggered and form a gap, and the swing through hole is formed on the connecting part and the buckling part. Therefore, by means of the design that the body part and the buckling part are staggered, the buckling part is connected with the swinging base block, and the body part is placed into the grounding jack to be abutted with the pin.
In order to facilitate the installation of the ground wire clip and the electric wire clip, the base body may include a base and a bottom cover in a split design, the bottom of the base is connected to the bottom cover, and the opening is formed at the top of the base. The base can be internally provided with a plurality of wiring channels matched with the electric jacks, the bottom cover is provided with a plurality of fixing convex blocks, the distribution positions of the fixing convex blocks correspond to the wiring channels, and after the base is covered with the bottom cover, the fixing convex blocks are embedded into the wiring channels. Therefore, the base and the bottom cover can be embedded into the wiring channel through the fixing convex blocks, so that connection and fixation are realized, and the base and the bottom cover are convenient to assemble.
When the plug and socket structure is applied to the wire slot, one wire in the wire slot can be selected as a signal transmission line for monitoring and regulating the state of the wire, but as the surface of the wire pin is generally coated with a coating, the coating is easy to oxidize under a high-temperature environment for a long time, so that poor contact between the electric plug and the electric socket is caused, and signal transmission is influenced. Therefore, after the electric wire pins corresponding to the electric wires for signal transmission are inserted into the electric wire female terminals, the convex blocks arranged on the inner walls of the clamping pieces can scratch the coatings on the surfaces of the electric wire pins, so that the clamping pieces can be directly conducted with the inner metal layers of the electric wire pins, the stability of signal transmission is ensured, and the condition that the signal transmission fails due to poor contact is avoided.
The invention has the advantages of safe use, difficult separation of the plug and the socket, simple operation, good grounding effect and the like.
