Embodiment Construction
[0046] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0047] like figure 1 As shown, this embodiment provides a contact plate fixing structure, including a body shell 1 and a contact plate 2, a slot 13 is formed on the body 1, and the slot 13 is limited after the contact plate 2 is inserted into a certain position. The contact plate 2 cannot continue to advance along its insertion direction, the contact plate 2 is formed with a boss 21, and the body 1 is formed with a hole for the boss 21 to be inserted at a position corresponding to the boss 21. Elastic card slot, when the boss 21 is inserted into the elastic card slot, it squeezes the elastic card slot and deforms continuously, and is limited by the slot 13 when ...

The invention provides a contact plate fixing structure which comprises a body and a contact plate. An inserting groove is formed in the body, and the inserting groove prevents the contact plate from continuing to advance in the inserting direction of the contact plate after the contact plate is inserted into a certain position. A boss is formed on the contact plate, an elastic clamping groove allowing the boss to be inserted into is formed in the position, corresponding to the boss, of the body, when the contact plate is inserted into the certain position in the inserting groove and cannot continue to advance by being limited by the inserting groove, the elastic clamping groove and the boss form an inverted buckling and locking structure so that the contact plate cannot move in the direction opposite to the inserting direction of the contact plate, the contact plate can be located in the direction opposite to the inserting direction of the contact plate through the inverted buckling and locking structure, and the situation that the contact plate is loosened in the direction opposite to the inserting direction of the contact plate in the work process is avoided. The contact plate is located in the direction opposite to the inserting direction of the contact plate, other parts are not added, and production cost is low.
Description
technical field [0001] The invention relates to a contact plate fixing structure, which belongs to the technical field of low-voltage electrical appliances. Background technique [0002] A contactor is an automatic control appliance that uses a coil to flow current to generate a magnetic field to close the contacts to control the load. A contactor is usually composed of an electromagnetic system, a contact system, an arc extinguishing device, an insulating body and accessories, etc. The contact system includes a static contact assembly and a moving contact, and the moving contact is usually set in linkage with the armature of the electromagnetic system. When the coil is energized, the armature drives the moving contact to cooperate with the corresponding static contact assembly, thereby turning on the load power. The static contact assembly is generally composed of a contact plate and a static contact. The static contact is fixed on the contact plate, and the contact plate ...
