Abstract

A split type double switch with up-bent terminals includes a key, a base, a hull, a on-off switch device consisting of a forward gangway, a moving contact, a bracket, a stationary contact, and a on-off switch device consisting of backward gangway, a moving contact, a bracket, a stationary contact. Under the pressure of the steel ball under the key, the parallel forward and backward gangways become upward or downward at one time, consequently, the moving contact under the forward gangway and the moving contact above the backward gangway contacts or separates from their corresponding stationary contact. The two bracket terminals vertically are inserted the front and back of the base; the two contact terminals are horizontally arranged and inserted in the bottom of the base and the connecting ends is bended upward; slots and protrusions with matching shapes corresponding to the contact terminals are arranged on the base, and at the bottom of the hull are corresponding protrusions and slots. Thereby, the bottom sides of the base and the hull can be tightly connected; the utility is easy to be assembled with high qualification rate, and is safe and reliable in use.

Description

A kind of split type input terminal is the double-pole switch of bending upwards

Technical field

The utility model relates to a kind of appliance switch, the upper and lower separation of specifically a kind of switch case, and input terminal is the double-pole switch of bending upwards.

Background technology

Existing double-pole switch, its four pin conducting terminal all be basically successively straight cutting on base.Other has a kind of double-pole switch, its first, fourth order conducting terminal straight cutting in the base rear and front end, second and third order conducting end transverse splicing arranged side by side is in the centre of base, for example my application number of application is " 200520015081.9 ", " moving seesaw-type double-pole switch ", " 200520116347.9 ", " novel moving seesaw-type double-pole switch ", they are for the supply socket of some specific (special) requirements, and positive effect has been played in the circuit interconnection when preventing the socket installation.But the double-pole switch of this form, because the switch pedestal width is limited, the two pin conducting terminal close together of transverse splicing in the middle of base, especially when this centre two pin during as input terminal, can cause live wire and ground wire the two poles of the earth bus distance of supply socket to lean on very closely, so not only make troubles to installation, and the accident that meets accident easily.Again then, traditional double-pole switch, its conducting terminal all are to rely on riveted joint that it is fixed on the base, if a carelessness slightly gently then causes conducting terminal loosening during riveted joint, influence product percent of pass, heavy then make conducting terminal and base plastics in addition parts scrap, cause unnecessary loss.Moreover, traditional double-pole switch, it is an integral body that its first half and electrical equipment connecting portion and Lower Half and base fasten the position, brings many inconvenience for the assembling and the dismounting of switch.

Summary of the invention

The purpose of this utility model is at the defective of above-mentioned prior art and deficiency, and the double-pole switch of a kind of easy to assembly, novel structure, function admirable is provided for the appliance switch industry.

The technical solution of the utility model is achieved in that this double-pole switch comprises button, base and housing, two groups of break-make switching device shifters parallel to each other are housed in the housing, by the support terminal, shelve the forehand springboard on it, be fixed on the moving contact of forehand springboard lower head and the corresponding with it fixed contact that is fixed on the contact terminal is formed one group of forehand break-make switching device shifter, by another support terminal, shelve anti-on it make springboard and be fixed on the moving contact of its above-head and with it the fixed contact on the contact terminal of being fixed on of correspondence form another and organize the anti-disconnected switching device shifter of getting through, just, it is parallel to each other instead to make springboard, arranged side by side end to end, steel ball below button compresses down, depress synchronously or perk, respectively be in the below and be positioned at above corresponding moving contact synchronizing close or separate, described just shelving, the anti-support terminal of making springboard vertically is plugged in the rear and front end of base, two contact terminals transverse splicing arranged side by side is both sides in the middle of base, and an end of contact terminal is bending upwards; Described base is provided with groove and the projection that the contact terminal bottom shape is complementary; The bottom of housing is provided with projection and the groove that is complementary with the contact terminal shape, contact terminal is pressed be fixedly connected on the base; It is disconnected from each other that the first half band bayonet socket of housing and electrical equipment connecting portion and housing Lower Half and base fasten the position, has a style of one's own; Second position of housing is that lower house and base fasten mutually with seam; Described two contact terminals that are assemblied in the base centre connect the live wire and the zero line of power supply, are the input terminal of switch.

The utility model is provided with groove and the projection that is complementary with the conducting terminal shape respectively on base and bottom the lower house, just need not rivet and conducting terminal can be fastened on the base securely, has improved the qualification rate of product.And the band buckle part that housing top and electrical equipment is fixing and disconnected from each other with the base position that is fastened and connected makes switch assembling, dismounting more convenient.Simultaneously with two input terminals of centre, its end towards the upwards bending of housing outer wall, has been strengthened switch two die openings, both be convenient in supply socket, assemble, improved the security performance of switch again.
