Description

Technical Field

[0001] The utility model relates to a contactor, in particular to a small contactor which is easy to install. Background Art

[0002] A contactor is an electrical appliance in industrial electricity that uses current flowing through a coil to generate a magnetic field to close the contacts in order to control the load. It consists of an electromagnetic system, a contact system, and an arc extinguishing device. It can be used to control the power loads of factory equipment, electric heaters, machine tools, and various power units. The contactor can not only connect and disconnect the circuit, but also has a low-voltage release protection function.

[0003] Existing contactors are usually fixed directly to the outer wall with multiple bolts. Although they can be installed quickly, all bolts need to be removed for inspection, maintenance and replacement, which increases the operating procedures. In addition, the outside of the contactor does not have the function of protecting the contactor, and it is easily damaged by impact from foreign objects, increasing the cost of use. Utility Model Content

[0010] Preferably, a column groove is provided at a position of the protective shell corresponding to the cylinder.

[0011] Preferably, the thickness of the block is slightly smaller than the depth of the limiting groove.

[0012] Beneficial effect: When the utility model is used, the bolt is fixed at the installation position through the installation hole of the installation block to complete the installation and use of the protective shell. When the contactor body is installed, the contactor body is placed inside the protective shell. After the placement is completed, the turning handle is pushed, and the turning handle pushes the cylinder, and the cylinder pushes the card block, so that the card block is pushed into the insertion slot until it is pushed flush with the limit slot. At this time, the turning handle is turned again, and the turning handle rotation drives the cylinder to rotate, and the cylinder rotation drives the card block to rotate. The card block rotates into the limit slot to complete the installation. When disassembling, the card block is turned from the limit slot to the insertion slot, and then pulled outward so that the card block is pulled to the limit block. At this time, the contactor body can be removed, which is convenient for the installation, use and disassembly of the contactor body. The utility model has a novel structure and a clever design, which is convenient for the installation and use of the contactor body and the disassembly during repair or maintenance, and is convenient for use.
