Abstract

The utility model relates to a sensitive switch, which is a high-power sensitive switch, comprising a base, a cover plate, a button, a normally open pin, a normally close pin, a moving contact, a bracket and a spring. The cover plate is buckled on an upper surface of the base, the button is inserted on the base, the normally open pin, the normally close pin and the bracket are respectively tabled on the base, the moving contact is sleeved on the bracket, an insulation pole is arranged on the button, a spring fixed point is arranged on the moving contact, two ends of the spring are respectively with the insulation pole of the button and the spring fixed points of the moving contact. The spring is of olive shape. The utility model also includes a reset spring, arranged between the button and the inner side wall of the base. Since the spring is respectively connected with the insulation pole of the button and the spring fixed points of the moving contact, the spring is not passed through current, thereby avoiding easy breaking after electrifying the spring. In addition, moving parts of the utility model are pressed with two metal sheets into an integer, which is simple in structure and low in cost.

Description

A kind of high-power sensitive switch

Technical field

The utility model relates to sensitive switch, particularly relates to a kind of high-power sensitive switch.

Background technology

The motive position of Extension Spring-type sensitive switch in the market is made up of a plurality of metallic stamping pieces, cost is higher, the wasting of resources is bigger, switch extension spring through excessive current work the time is worked under charged situation, extension spring is fracture easily after conduction work, make the switch cisco unity malfunction, cause very big prestige to assist for people's life security.In addition, through excessive current work the time, the switch contact point is easy to cling, and can not disconnect, and does not meet the GB15092.1-2003 standard, and very big potential safety hazard is arranged.

The utility model content

Technical problem to be solved in the utility model is to solve the problem that there is potential safety hazard in sensitive switch.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of high-power sensitive switch, comprise: pedestal, cover plate, button, often open pin, normally closed pin, moving contact, support and spring, the leading flank of described pedestal is provided with and is used to install the open slot of often opening pin and normally closed pin, and two opposite side surfaces of pedestal are respectively equipped with open slot that installs support and the open slot that installs button; Described cover plate spiral-lock is on the upper surface of pedestal; Described button outwards is inserted on the pedestal by base interior; Described pin, normally closed pin and the support often opened is inlaid on the pedestal respectively, and be placed on button and often open, between the normally closed interlock; Described moving contact is provided with support and installs through hole, and is that moving contact is arranged on base interior and be sleeved on the support; Described button is provided with insulated column, and moving contact is provided with the spring fixing point, the two ends of spring respectively with button on insulated column be connected with spring fixing point on the moving contact.

Described spring is olive-shaped.

The utility model also comprises back-moving spring, and described back-moving spring is along being arranged on the button moving direction between button and the pedestal madial wall.

The utility model because spring respectively with button on insulated column and the spring fixing point of moving contact be connected, so obstructed overcurrent of spring itself has been avoided the spring energising back problem of fracture easily, and can have been passed through bigger electric current, is applicable to high-power circuit.In addition, movable part of the present utility model is formed by the two metal sheets integrated punching, and is simple in structure, saved cost greatly.

Embodiment

Below in conjunction with accompanying drawing the utility model is made detailed explanation.

As shown in Figure 1 and Figure 2, the utility model comprises pedestal 1, cover plate 12, button 2, often opens pin 4, normally closed pin 5, moving contact 6, support 3 and spring 7, the leading flank of described pedestal 1 is provided with and is used to install the open slot of often opening pin 4 and normally closed pin 5, and two opposite side surfaces of pedestal 1 are respectively equipped with the open slot that installs support 3 and install the open slot of button 2; Described cover plate 12 spiral-locks are on the upper surface of pedestal 1; Described button 2 outwards is inserted on the pedestal 1 by pedestal 1 inside; Described pin 4, normally closed pin 5 and the support 3 often opened is inlaid in respectively on the pedestal 1, and support 3 places button 2 and often opens, between the normally closed interlock, often opens on pin 4, the normally closed pin 5 and be respectively equipped with

contact

10 and 11; Described moving contact 6 is provided with the through hole that installs of support 3, and is that moving contact 6 is arranged on pedestal 1 inside and be sleeved on the support 3, is respectively equipped with contact 9 on the two sides of the outer end of moving contact 6.

Again as shown in Figure 3, described button 2 is provided with insulated column 20, the two ends of spring 7 respectively with button 2 on insulated column be connected with spring fixing point on the moving contact 6.Described button 2 is provided with C type groove, and moving contact 6 is sleeved in the C type groove on the button 2.

At ordinary times, the contact of the utility model moving contact 6 contacts with contact 11 on the normally closed pin 5, and when pressing button 2, moving contact 6 moves down under the drive of button 2, so the contact 9 on the moving contact 6 contacts with contact 10 on often opening pin 4.If electric current is excessive, cling the contact, can utilize the C shape channel parts on the button 2 that the contact is forced to disconnect.Thereby can reach the GB15092.1-2003 standard, can not cause prestige association the life security of human body.

As shown in Figure 4, described spring is olive-shaped.

Referring to Fig. 1 and Fig. 5, the utility model also comprises back-moving spring 8 again, and back-moving spring 8 is along being arranged between the madial wall of button 2 and pedestal 1 on button 2 moving directions.

It is less that the utility model, spring drive the driving mechanism parts of the moving switch that declines, and can effectively control product quality and consistency in process of production, makes production more convenient, thereby output is improved.The utility model is widely used in lathe power supply, household electrical appliance, hardware ﹠ tools, electric tool, instrument and meter etc.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection range of the present utility model.
