Description

Technical Field

[0001] The invention relates to the field of high-voltage electrical connectors, and in particular to a pluggable high-voltage electrical connector. Background Art

[0002] A high-voltage electrical connector is a device used to achieve safe and reliable electrical connections in high-voltage electrical systems. This type of connector is mainly used for connections between high-voltage transmission and distribution systems and various high-voltage electrical equipment. In mines, it is used to connect high-voltage electrical equipment, such as cables, transformers, switch cabinets, etc., to ensure the continuity and reliability of power transmission. At present, when high-voltage electrical connectors are used in mines, the wires on the high-voltage electrical equipment are fixed at both ends of the connector, and then the connectors are docked to connect the wires. However, since the connectors may be stuck and difficult to separate after docking, when the wires leak, it is not convenient for the staff to disconnect the wires in time, which may easily lead to electric shock accidents and is more dangerous.

[0003] Therefore, a pluggable high-voltage electrical connector has been developed which can push out a connection plug when the electric wire leaks electricity, so as to disconnect the electric wire and avoid electric shock accidents. Summary of the invention

[0004] In order to overcome the disadvantages that high-voltage electrical connectors may become stuck and difficult to separate after docking, and when the wires leak, it is inconvenient for workers to disconnect the wires in time, which may easily lead to electric shock accidents and is relatively dangerous, the present invention provides a pluggable high-voltage electrical connector that can push out the connecting plug when the wires leak, so as to disconnect the wires and avoid electric shock accidents.

[0005] The technical solution is: a pluggable high-voltage electrical connector, including a guide frame, a positioning frame, a first fixing screw, a connecting component, a first wiring component, a second wiring component and a positioning component. The upper and lower parts of the guide frame are both clamped with the positioning frame, and the positioning frame is threadedly connected with the first fixing screw, and the first fixing screws are in contact with the guide frame. The guide frame is provided with a connecting component that can connect to the wires, the connecting component is provided with a first wiring component that can connect the wires, and the connecting component is also provided with a second wiring component that can connect another wire. The connecting component is provided with a positioning component that can push out the wires, the connecting shell is pushed into the guide frame, and then the positioning frame is clamped and matched with the guide frame, the positioning frame is installed and fixed at the high-voltage electrical connection position, and the guide frame and the positioning frame are fixed by the first fixing screw, so that the positioning frame fixes the guide frame.

[0006] Furthermore, the connecting component includes a connecting shell, a guide column, a plug plate and a spring. The connecting shell is clamped in the middle of the guide frame, the guide column is slidably connected inside the connecting shell, the plug plate is connected to the front side of the guide column, and a spring is connected between the plug plate and the connecting shell.

[0007] Furthermore, the first wiring assembly includes a connecting hollow column, a conductive plate, a conductive rod and a second fixing screw. The connecting hollow column is threadedly connected to the rear side of the connecting shell, the conductive plate is connected inside the connecting hollow column, the conductive plate is connected to the front side of the conductive plate, the conductive rod is in contact with the guide column, and the connecting hollow column is threadedly connected to the second fixing screw. The connecting hollow column is connected to the connecting shell, and then the wire to be connected is inserted into the connecting hollow column so that the wire is in contact with the conductive plate. The second fixing screw is rotated to move it downward, so that the second fixing screw presses the wire.

[0008] Furthermore, a cross groove is formed on the second fixing screw.

[0009] Furthermore, the second wiring assembly includes a connecting plug and a third fixing screw. The connecting plug is clamped on the front of the connecting shell, and the connecting plug is clamped and matched with the plug board. The third fixing screw is threadedly connected to the connecting plug. Another wire to be connected is inserted into the connecting plug, and the wire is pressed and fixed by moving the third fixing screw downward. Then, the connecting plug is pushed into the connecting shell to dock with the plug board, and at the same time, the plug board is squeezed to move backward. The spring is squeezed and contracted, and the guide column moves backward and contacts the conductive rod, so that the wires are connected to each other.

[0010] Furthermore, the locking assembly includes a threaded sleeve, a rotating frame and a locking plate. The rear part of the guide column is connected to the threaded sleeve, and the rotating frame is threadedly connected to the threaded sleeve. The rotating frame passes through the connecting shell, and the upper and lower parts of the rotating frame are connected to the locking plates. The locking plates are engaged with the connecting plug. When the guide column moves backward, it drives the threaded sleeve to move backward, so that the rotating frame rotates, drives the locking plate to rotate, and makes the locking plate engage with the connecting plug. When the wire leaks and needs to be disconnected, the rotating frame is rotated to make the locking plate detach from the connecting plug, and at the same time the guide column moves forward, the spring rebounds, and the plug plate moves outward, pushing the connecting plug to move outward.

[0011] Furthermore, the threaded sleeve is made of insulating material.

[0012] Furthermore, it also includes a wire clamping assembly, which includes a fixed bracket, a connecting bracket, a torsion spring and a clamping plate. The fixed brackets are connected to the left and right sides of the front of the connecting plug. The connecting brackets are rotatably connected to the fixed brackets. The connecting brackets are connected to the fixed brackets with two upper and lower torsion springs. The connecting brackets are connected to the fixed brackets. When another wire to be connected is inserted into the connecting plug, the connecting brackets on the fixed bracket are rotated to move away from each other, driving the clamping plates to move away from each other, and the torsion spring is deformed. After the wire is inserted into the connecting plug, the connecting bracket is released, and the torsion spring is restored, so that the connecting bracket drives the clamping plates to move closer to each other and contact the wire.

[0013] Furthermore, protrusions are provided on the clamping plates.

[0014] Furthermore, it also includes a fixing component, which includes a connecting block, a connecting fixing frame and a fourth fixing screw. The upper and lower sides of the rear portion of the rotating frame are connected to the connecting blocks, the upper and lower sides of the rear portion of the connecting shell are connected to the connecting fixing frames, and the connecting fixing frames are threadedly connected to the fourth fixing screws. The fourth fixing screws are snap-fitted with adjacent connecting blocks. After the positioning plate is snap-fitted with the connecting plug, the connecting fixing frame is aligned with the connecting block, and the fourth fixing screw is rotated to move the fourth fixing screw to snap-fit ​​with the connecting block.

[0015] The beneficial effects of the present invention are as follows: 1. When the electric wire needs to be disconnected due to leakage, the present invention rotates the rotating frame to disengage the locking plate from the connecting plug, and at the same time moves the guide column forward, and the spring rebounds to move the plug plate outward, pushing the connecting plug outward, thereby achieving the effect of being able to push out the connecting plug when the electric wire leaks, so as to facilitate disconnection of the electric wire and avoid electric shock accidents.

[0016] 2. The present invention moves the threaded sleeve backward while the guide column moves backward, so that the rotating frame rotates, and the locking plate rotates, so that the locking plate and the connecting plug are engaged with each other, thereby achieving the effect of fixing the connecting plug on the connecting shell and preventing the connecting plug from loosening.

[0017] 3. The present invention rotates the connecting brackets on the fixed bracket to move them away from each other, drives the clamping plates to move away from each other, and deforms the torsion spring. After the wire is inserted into the connecting plug, the connecting bracket is released and the torsion spring is restored, so that the connecting bracket drives the clamping plates to move closer to each other and contact the wire, thereby achieving the effect of clamping the wire and preventing the wire from loosening and falling from the connecting plug.

[0018] 4. After the positioning plate and the connecting plug are engaged with each other, the fixing frame is aligned with the connecting block, and the fourth fixing screw is rotated to move the fourth fixing screw to engage with the connecting block, thereby fixing the rotating frame and preventing the rotating frame from rotating accidentally.
