Problems solved by technology

The current electrical components are divided into double breakpoint and single breakpoint according to the composition of the contact components. The performance of the electrical component with the bridge double breakpoint structure is reliable, but the cost is expensive, and it needs to consume too much contact material, especially for high current. electrical components (current > 32A), the contact material is generally silver alloy, and the material cost is high
According to the movement mode, electrical components are divided into two types: rotary type and parallel type. In the current single break point rotary type electrical components, one end of the moving contact is usually fixed as a fulcrum by punching, riveting and other processes, and the other end of the moving contact is fixed. One end is closed or broken with the static contact, which has the defects of complex process and high cost
In addition, during the closing or breaking process of the moving contact and the static contact, due to arc ablation, mechanical wear and other reasons, the contact between the moving contact and the static contact will be worn, while the shaft end with a fixed fulcrum is basically There will be no wear on the surface, so it will cause a height difference between the two ends of the contact, which will lead to an unbalanced contact structure and affect the normal use of the product

Embodiment 1

[0026] Such as figure 1 As shown, this embodiment discloses an electrical component. In this embodiment, the electrical component can be used as a contactor. The electrical assembly includes a housing, a contact assembly disposed in the housing, and a support structure 160 relatively fixed to the housing. Wherein, the contact assembly includes a static contact 150, a moving contact 120, and a contact supporting part for supporting the moving contact, and one end of the moving contact 120 can be in contact with or separated from the support structure 160, The other end of the movable contact 120 can be in contact with or separated from the static contact 150 . In this embodiment, the support structure 160 can be in contact with or separated from the movable contact 120. After the movable contact 120 is in contact with the static contact 150, the movable contact 120 Driven by the supporting part, it moves for a certain distance and contacts with the supporting structure 160 ....

Embodiment 2

[0046] like figure 2 As shown, this embodiment discloses another electrical component. The electrical component in this embodiment can be used as a contactor. In this embodiment, the electrical component includes a support structure 260 corresponding to the position-limiting structure. When the movable contact 220 moves towards the static contact 250 under the action of the contact supporting part, the support structure 260 can support one end of the movable contact 220 so that the movable contact 220 is supported by the contact. Closed with the static contact 250 under the action of the part.

[0047] In this embodiment, in order to realize the electrical connection between the moving contact 220 and the external circuit, the electrical component further includes a conductive terminal block 270 electrically connected to the external circuit, and the moving contact 220 can be connected to the conductive wiring through a flexible connection wire 240 The socket 270 is electr...

Embodiment 3

[0051] like image 3As shown, this embodiment discloses another electrical component. The electrical components in this embodiment can be used as electromagnetic relays, specifically, as magnetic latching relays. The electrical assembly in this embodiment includes a contact assembly and a supporting structure 360 ​​. The contact assembly includes a static contact 350 , a moving contact 320 and a contact supporting part 310 supporting the moving contact 320 . The contact supporting part 310 can move under the force of the electromagnetic assembly and drive the moving contact 320 to move, the supporting structure 360 ​​can contact or separate from the moving contact 320, and the moving contact 320 After being in contact with the static contact 350 , the moving contact 320 is driven by the contact supporting part 310 to move for a certain distance and then contact with the support structure 360 ​​. The electrical component also includes a limiting structure 330 corresponding t...

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to an electrical component. Background technique [0002] Electrical components are an important part of the circuit structure. By controlling the electrical components, the switching, control, protection and detection of the circuit are realized. Electrical components, including contactors and relays, usually flow into the coil to generate a magnetic field through the current to close the contacts. to control electrical loads. The current electrical components are divided into double breakpoint and single breakpoint according to the composition of the contact components. The performance of the electrical component with the bridge double breakpoint structure is reliable, but the cost is expensive, and it needs to consume too much contact material, especially for high current. For electrical components (current > 32A), the contact material is generally s...
