Description

Technical Field

[0001] The utility model relates to the technical field of arc-extinguishing grid assembly, in particular to an arc-extinguishing grid assembly tool. Background Art

[0002] In a broad sense, a contactor refers to an electrical appliance in industrial electricity that uses a coil to generate a magnetic field to close the contacts in order to control the load. It is used in power, distribution and electricity use.

[0003] A known authorized invention (publication number: CN113270295B) discloses a contactor arc-extinguishing grid installation device, including a positioning mechanism and a pressing mechanism, wherein the positioning mechanism includes a base, a dynamic pressing member and a static pressing member, wherein the dynamic pressing member is telescopically arranged on the base, an elastic member is arranged between the dynamic pressing member and the base and is pressed against the dynamic pressing member, wherein the static pressing member is fixedly arranged on the base, wherein the static pressing member has a guide structure capable of driving the arc-extinguishing grid leg to deform during pressing, wherein the pressing mechanism includes a pressure head abutting against the arc-extinguishing grid, and a driving module for driving the pressure head to move toward the positioning mechanism, wherein the elastic force applied by the elastic member to the dynamic pressing member is greater than the force required to be applied when the arc-extinguishing grid is plugged and clamped into the arc-extinguishing grid slot. The present invention can simply and quickly install and position the arc-extinguishing grid on the arc-extinguishing cover;

[0004] When the device is in use, although it can simply and quickly install and position the arc-extinguishing grid on the arc-extinguishing cover, the device lacks an elastic adjustment mechanism. A spring component is integrated in the device, and the spring component can provide sufficient elastic force in the initial use state to ensure that the arc-extinguishing grid is firmly installed on the arc-extinguishing cover. However, with the passage of time and the continuous use of the device, the elasticity of the spring component will gradually weaken. This is because the material of the spring will fatigue during the long-term compression and release process, resulting in a decrease in its restoring force. When the elasticity of the spring is weakened to a certain extent, it will not be able to provide sufficient force to ensure the stable installation of the arc-extinguishing grid, which may cause the performance of the equipment to decline and even cause safety hazards. For this reason, an arc-extinguishing grid assembly tool is proposed. Utility Model Content
