DESCRIPTION
LU601864
GROUNDING DEVICE FOR ELECTRICAL PROTECTION
TECHNICAL FIELD
The present invention relates to the technical field of grounding devices, and specifically to a grounding device for electrical protection.
BACKGROUND
A grounding device for electrical protection is a critical safety facility in power systems and electrical equipment, designed to ensure personal safety, maintain normal equipment operation, and prevent electrical fire accidents. By establishing a reliable electrical connection between specific components of electrical equipment and the earth, the fault currents can be rapidly diverted into the ground during equipment malfunctions, effectively limiting the ground potential voltage on equipment enclosures, thereby preventing electric shocks to personnel while simultaneously protecting equipment from damage.
Under normal conditions, non-energized parts of electrical equipment such as metal enclosures are insulated from the ground. When the equipment experiences a fault such as insulation failure, for instance, if the live wire inside comes into contact with the enclosure causing a short circuit, the enclosure will become electrified. At this point, if the equipment is mounted with a grounding device, the fault current will flow to the ground through the grounding conductor, completing a circuit. Due to the relatively low resistance of the earth, the fault current increases rapidly, causing protective devices such as fuses or circuit breakers to activate and interrupt the faulty circuit, thereby preventing electric shock to personnel and equipment damage.
Common grounding devices involve connecting one end of the grounding wire to the metal enclosure of electrical equipment and the other end to a natural or artificial grounding body. However, traditional grounding methods such as welding or permanent bolt connections can be inconvenient during installation and maintenance, especially for equipment requiring frequent relocation or inspection. Therefore, a grounding device for electrical protection is provided to solve these problems.

I. Technical solutions
To realize the above objective, the present invention provides the following technical solutions. The present invention provides a grounding device for electrical protection, including: a plug housing, an insulated wire and a clamp body, three-phase sockets being disposed at a front end of the plug housing, and the three-phase sockets being integrally formed with the plug housing; a neutral and live conductive contact housing, arranged on front and rear sides of an upper end of an interior of the plug housing, and the neutral and live conductive contact housing being fixedly connected to the plug housing; a neutral and live contact blade, arranged at an exterior of the neutral and live conductive contact housing, and the neutral and live contact blade being fixedly connected to the neutral and live conductive contact housing: a grounding conductive contact housing, arranged at a lower end of the interior of the plug housing, and the grounding conductive contact housing being fixedly connected to the plug housing; a grounding contact blade, arranged at an exterior of the grounding conductive contact housing, and the grounding contact blade being fixedly connected to the grounding conductive contact housing; a conductive frame, arranged at the exterior of a lower end of the grounding conductive contact housing, and the conductive frame being fixedly connected to the grounding conductive contact housing; a second conductive ring, arranged at one end of an exterior of the insulated wire close to the conductive frame, the second conductive ring being fixedly connected to the insulated wire, and the second conductive ring being connected to the conductive frame through a second fixing bolt; and a first conductive ring, arranged at one end of the exterior of the insulated wire facing away from the conductive frame, and the first conductive ring being fixedly connected to the insulated wire.
Preferably, a first fixing bolt is arranged inside the first conductive ring, and the first fixing bolt is movably connected to the first conductive ring. The first fixing bolt allows the 091868 first conductive ring to be connected to the clamp body or the metal enclosure of electrical equipment.
Preferably, the clamp body includes a conductive lower clamp plate and a conductive upper clamp plate, the conductive lower clamp plate is rotatably connected to the conductive upper clamp plate, the first fixing bolt and the conductive upper clamp plate are connected by a screw-thread fit, anti-slip teeth are arranged at outside edges of an upper end of the conductive lower clamp plate and a lower end of the conductive upper clamp plate, and the anti-slip teeth are fixedly connected to the conductive lower clamp plate and the conductive upper clamp plate. Through the anti-slip teeth, the clamping of the conductive lower clamp plate and the conductive upper clamp plate is more stable.
Preferably, a first insulating plate is arranged at one end of an exterior of the conductive lower clamp plate, the first insulating plate is fixedly connected to the conductive lower clamp plate, a second insulating plate is arranged at one end of an exterior of the conductive upper clamp plate, and the second insulating plate is fixedly connected to the conductive upper clamp plate. One end of the exterior of the conductive lower clamp plate is insulated by the first insulating plate, and one end of the exterior of the conductive upper clamp plate is insulated by the second insulating plate, thereby facilitating control of the opening and closing of the conductive upper clamp plate and the conductive lower clamp plate through the first insulating plate and the second insulating plate.
Preferably, a return spring is mounted between the first insulating plate and the second insulating plate, and upper and lower ends of the return spring are fixedly connected to the first insulating plate and the second insulating plate.

Preferably, an adjusting bolt is mounted inside the second insulating plate, the adjusting bolt and the second insulating plate are connected through a screw-thread fit, a limiting hole is disposed at an interior of a lower end of the first insulating plate, and the adjusting bolt is adapted to the limiting hole. The adjusting bolt rotates, the rotational motion of the adjusting bolt is converted into the linear motion under the screw-thread fit of the adjusting bolt and the second insulating plate, causing the adjusting bolt to move toward or face away from the first insulating plate as it rotates.
When the adjusting bolt moves toward the first insulating plate, it restricts the movement of the first insulating plate, causing the conductive lower clamp plate and the 97964 conductive upper clamp plate to be clamped and fixed, thereby enhancing the stability of the clamp body when clamping the metal enclosure of electrical equipment. Conversely, when the adjusting bolt moves toward one side facing away from the first insulating plate, the restriction on the first insulating plate is released, allowing the first insulating plate and the second insulating plate to be pressed, further separating the conductive lower clamp plate and the conductive upper clamp plate, thereby releasing the clamping. The limiting hole is used for the insertion of the adjusting bolt.
Preferably, side blocks are arranged on two sides of an exterior of the plug housing, and the side blocks are fixedly connected to the plug housing. The side blocks can increase the grip volume of the plug housing, facilitating the insertion and removal of the plug housing.

The anti-slip strips are used for improving the anti-slip performance of the exteriors of the side blocks. When the plug housing needs to be removed, fingertips abuts against the exteriors of the anti-slip strips of the side blocks, and the plug housing is pulled outward after the side blocks are clamped with the fingertips, thereby facilitating the disassembly of the plug housing.
