Abstract

A blocked typed AC contactor (a base) belongs to the field of AC contactors. Assembling-disassembling and changing can be realized by hand without any tool when repairing and changing the internals. The invention reduces metal pieces such as fix screws, thus reducing the whole weight of the AC contactor greatly, and the invention also removes metal pieces in the AC contactor such as fastening screws, increasing the creepage distance, the dielectric strength and the defense grade in the AC contactor greatly. A cardy 9 on the base, a disassembling groove 10 and two blocking grooves 6 and 8 of the contactor blocking elements are arranged on a shell 4 at one time.

Description

Car coat type alternating current contactor (base)

Technical field

The invention belongs to the A.C. contactor field.

Background technology

The A.C. contactor of routine all is to assemble with securing members such as screws basically in the low-voltage electrical apparatus field.There is certain defective in it: the time must use corresponding instrument as assembling, and operation, demolition, installation are all inconvenient; Simultaneously, because there is the existence of metalworks such as holding screw A.C. contactor inside, make creepage distance, dielectric strength and the degree of protection of A.C. contactor all be subjected to a certain degree influence.

Summary of the invention

The objective of the invention is:

A.C. contactor made does not need holding screw and instrument, the free-hand novel A.C. contactor that can carry out assembly and disassembly; The metalworks such as holding screw of cancellation A.C. contactor inside are effectively alleviated the weight of A.C. contactor itself; Creepage distance, dielectric strength and the degree of protection of A.C. contactor are effectively improved.

Realize that method of the present invention is:

With the shell of A.C. contactor and the structural member that need assemble, assemble with the mode of stinging mutually, detaining; And it is when making, that its making is as a whole.

Advantage of the present invention is:

1. inner structural members is being keeped in repair, when changing,, do not needing to use any instrument, free-handly can finish demolition, installation and more change jobs as contact, coil etc.;

2. reduce metalworks such as employed fixed screw, the overall weight of A.C. contactor can be reached effectively alleviate;

Since the A.C. contactor in-discard metalworks such as holding screw, creepage distance, dielectric strength and the degree of protection of A.C. contactor inside are all effectively improved.

Concrete operation principle and implementation method

Car coat type alternating current contactor (base), its operation principle is as follows:

At first with relevant zero, the parts of A.C. contactor, as contact, spring, iron core, coil etc., after being stuck in the draw-in groove or Ka Tainei of corresponding site of base or loam cake, again loam cake and base are fastened, utilize the intrinsic elasticity of plastic products, the bayonet socket that covers is just in time snapped on the card platform 9 on the base, and chucking automatically; When needs dismountings or when changing parts, with finger from the dismounting groove with gently cocked of the bayonet socket of loam cake, loam cake can be taken off from base.

About the bayonet socket part of loam cake, will separate case application outside present patent application.

Car coat type alternating current contactor (base), specific implementation method is as follows:

When mold design, with all relevant bayonet sockets, draw-in groove, base station etc., disposable design moulding is through the A.C. contactor base behind injection moulding or the compression molding, all relevant bayonet sockets, draw-in groove, base station etc., all disposable being fabricated on the base.Therefore, car coat type alternating current contactor (base) clamps the positive the right card platform 9 that makes up usefulness with upper cover part; Dismounting groove 10 after the right side of car coat type alternating current contactor (base) and loam cake clamp; And the left contact component card holding trough 6 of car coat type alternating current contactor (base) all is disposable directly being produced on car coat type alternating current contactor (base) housing 4.And, also all be disposable directly being produced on car coat type alternating current contactor (base) housing 4 with the right card platform 9 and dismounting groove 10 corresponding left sides, right side and Ka Tai behind and dismounting groove.Simultaneously, being made up of several with left and right contact component

card holding trough

6,8, also all is disposable directly being produced on car coat type alternating current contactor (base) housing 4.

So far explanation has reached and inner structural members has been keeped in repair, when changing, as contact, coil etc., do not needing to use any instrument, free-handly can finish demolition, installation and more changes jobs; Reduce metalworks such as employed fixed screw, the overall weight of A.C. contactor can be reached effectively alleviate; Since the A.C. contactor in-discard metalworks such as holding screw, the purpose that creepage distance, dielectric strength and the degree of protection of A.C. contactor inside are all effectively improved.
