Technical Field

The invention relates to the technical field of equipotential connection of conducting wires, in particular to magnetic type conducting wire connecting devices.

Background

In many cases, due to safety and technical requirements, it is necessary to make equipotential connections, such as grounding of devices or metal structures, but when temporary or long-term equipotential connections are made, there are often situations where the device structure lacks a connection point for a wire, making the wire connection difficult, such as effective equipotential connection of the outer surface of an oil and gas pipeline to the ground for reducing the damage of static and lightning strikes, temporary grounding of various test electrical equipment, temporary grounding of a vehicle body when a tanker is loading and unloading oil, etc.

Disclosure of Invention

The invention aims to provide magnetic type wire connecting devices which are convenient, quick and reliable, so as to solve the problem that the wire connection is difficult due to the fact that the device structure is lack of wire connecting points and the like when temporary or long-term equipotential connection is carried out, and the device structure cannot be damaged.

Preferably, the magnet fixes the connected conductor on the metal surface to be connected by magnetic force, and the magnet is in contact with the device to be connected. The magnet fixes the connected conductor on the device to be connected through the magnetic force between the magnet and the device to be connected.

Preferably, during the wiring operation, the spring presses the wire and the device to be connected at through the pressing structure and the sawtooth structure, the wire pressing structure directly presses the wire on the external metal structure to realize the electrical conduction between the wire and the external metal structure, and the pressing force of the wire pressing structure on the wire comes from the combined action of the spring force and the magnet attraction force.

Preferably, the pressure generated by the spring and the sawtooth structure is larger than the force of the connected conductor breaking away the metal to be connected. The spring is connected with the outer frame structure and the lead crimping structure, generates elastic force and provides enough thrust for the lead crimping structure. The spring is connected with the outer frame structure and the lead crimping structure, generates elastic force and provides enough thrust for the lead crimping structure.

Preferably, the magnet is a permanent magnet, and the magnet may be plural.

Preferably, when the limiting block makes the length of the spring be the longest, the distance between the tooth top line of the sawtooth structure and the contact surface of the spring and the frame is not less than the height of the magnet in the direction of the symmetry axis of the frame.

Preferably, when the limiting block makes the length of the spring shortest, the distance between the tooth crest line of the sawtooth structure and the contact surface of the spring and the frame is not greater than the height of the magnet in the direction of the symmetry axis of the frame.

The beneficial effects obtained by the invention are as follows: the wire can be conveniently and quickly crimped to the device equipment to be connected or the metal structure of the wire-free connecting bolt without machining a threaded hole or welding a wire connecting mechanism on the device structure, so that the damage to the outer surfaces of the device and the metal structure is avoided.
