Description

Technical Field

[0001] The utility model relates to the technical field of copper bars, in particular to a grounding copper bar. Background Art

[0002] In the power system, in order to prevent electric shock or protect the safety of equipment, the metal chassis or casing of power and telecommunications equipment will be connected, and the ground wire will use the earth as the current loop ground wire. In the power system, the neutral point, casing or bracket of the equipment and electrical devices will be connected to the grounding device with a conductor for good electrical connection, which is called grounding. In addition to conducting some useless current or noise interference into the earth, the biggest function of grounding is to protect users from electric shock. In order to facilitate the grounding of equipment, a grounding copper busbar is generally set as the grounding point for each circuit, equipment, etc., and then the grounding is unified through the grounding copper busbar.

[0003] At present, when the commonly used grounding copper busbar is connected to the grounding wire of the equipment, the screw of the grounding copper busbar is loosened with a screwdriver, and the wire is inserted into the grounding copper busbar and then the screw is tightened. This connection method is cumbersome to operate and is easy to loosen when it is hit or vibrated, affecting the use effect. Utility Model Content

[0008] Furthermore, a plurality of groups of rubber bumps are provided at the bottom of the limiting plate.

[0009] By adopting the above technical solution, the rubber protrusion can further increase the friction with the fixing bolt, so that the fixing bolt is not easy to retreat.

[0010] Furthermore, a pull ring is fixed to the end of the pull rod, and the pull rod is movably connected to the fixing frame.

[0011] By adopting the above technical solution, the design of the pull ring makes it easier for the staff to pull the pull rod, making it more convenient for the pull rod to move upward.

[0012] Furthermore, the longitudinal section of the limiting column is trapezoidal, and the limiting column is located on the inner side of the through opening.

[0013] By adopting the above technical solution, the design can meet the needs of wire terminal rings with different diameters, so that the wires are not easily loosened by being pulled after being connected.

[0014] Furthermore, the pressing portion of the pressing plate is provided with anti-slip grooves.

[0015] By adopting the above technical solution and utilizing the design of anti-skid patterns, it is not easy to slip when applying pressure to the pressure plate.

[0016] Furthermore, the mounting bracket and the copper busbar body are an integrated structure.

[0017] By adopting the above technical solution, the production process is greatly simplified and the production cost is reduced.

[0018] Furthermore, the surface of the copper busbar body is plated with a nickel layer.

[0019] By adopting the above technical solution and using this electroplating method for anti-oxidation treatment, oxidation will not occur on the contact surface of the copper busbar body, thus ensuring reliable conductivity and good grounding effect.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. When the utility model is used to connect a wire, the worker first overcomes the elasticity of the first spring and presses the pressure plate, then places the wire terminal ring on the copper busbar body so that the hole of the wire terminal ring is aligned with the through opening, then releases the pressure plate, and under the elasticity of the first spring, the pressure plate drives the limiting column to move downward, and the limiting column passes through the wire terminal ring and the through opening to fix the wire, so that there is no need to use a screwdriver to tighten or loosen the wiring terminal to fix the position of the grounding wire on the wiring terminal, thereby solving the problem of cumbersome operation when assembling the grounding wire and improving the assembly effect. In addition, since the limiting column is trapezoidal, it can meet the needs of wire terminal rings of different diameters, and will not loosen when pulled or vibrated, thereby enhancing the safety of use.

[0022] 2. When installing the copper busbar, the utility model first pulls the pull rod to make the limit plate move upward, then inserts the fixing bolt, and then loosens the pull rod. Then the staff rotates the fixing bolt to fix the copper busbar. Under the action of the second spring, the limit plate will be pressed against the fixing bolt. Under the action of the pressure of the second spring and the friction force of the rubber bump, the fixing bolt can be prevented from rotating under the action of external vibration force, thereby improving the stability of the grounding copper busbar after installation.
