Abstract

The utility model relates to the field of electric elements, in particular to a switch with stable property and low noise. The switch comprises a base and an upper cover which are in buckle connection with each other, wherein a switch pin and a button component are arranged in the base; the button component is provided with an operation terminal extending out of the base; and a transferring link, on which a contact pin is arranged, is mounted on the button component, and pushed forwards along the pressed action of the button component, so as to enable the contact pin to switch on the switch pin. The utility model has reasonable structural design and convenient installation and removal, and the transferring link is designed to take the shape of a sheet, so as to ensure that the contact area of the transferring link and the switch pin is increased greatly, and improve the stability of the switch use; and the transferring link of the switch is in contact with the pin in a parallel pushing manner, thereby avoiding the problem of large noise of a rocker switch and the like which realize the contact switch through the deformation of metal sheets.

Description

A kind of switch

Technical field

The utility model relates to the electric component field, specifically is meant a kind of stable performance, the switch that noise is little.

Background technology

Switch is widely used in the daily life.But it is bad that a lot of switches occur contacting in use easily, uses unsettled situation.In addition in order to prevent that switch from use producing big noise, people have gradually adopted conductive rubber and contact construction of switch, though conductive rubber and contact switch have reduced the sound that uses switch, but use switch service time long afterwards or under adverse circumstances, the distortion that gets rusty easily of switch inner body, cause coming in contact condition of poor, influence the normal use of switch.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of stable performance, the contact very little switch of noise well and in use is provided.

For achieving the above object, the technical scheme that provides of the utility model is:

Design a kind of switch, comprise base and loam cake that mutual buckle connects, be provided with switch pin and button assembly in the base, button assembly is provided with the operating side, the operating side protuberate basic unit, on the described button assembly transfer strip is installed, transfer strip is provided with haptic element, and transfer strip is pressed action with button assembly and passes forward and make haptic element connect the switch pin.

Concrete, described transfer strip is provided with two haptic elements at least; The termination that described transfer strip haptic element contacts with the switch pin is a sheet, and the whole bottom surface of sheet termination is the contact-making surface with the switch pin.

Concrete, a cylinder is set in the described base, be socketed with back-moving spring on the cylinder, back-moving spring one end props up button assembly, and impelling upsprings by the button assembly of depressing resets; Described button assembly is respectively arranged with reference column in both sides up and down near back-moving spring place one end, and base and loam cake are provided with and the corresponding circular hole of reference column.

With respect to prior art, the beneficial effects of the utility model are: the utility model reasonable in design, and easy installation and removal, the transfer strip termination is set to sheet increases itself and switch pin contact area greatly, has increased the stability that switch uses; Described switch transfer strip adopts the mode of parallel passing to realize contacting with pin, has avoided dependence sheet metal deformation such as wane type switch to realize that the switch of contact produces the big problem of noise.

Accompanying drawing 1 is the utility model embodiment decomposition texture schematic diagram;

Accompanying drawing 2 is that the utility model embodiment assembles the back schematic diagram;

Accompanying drawing 3 is the utility model embodiment base structural representations.

Embodiment

For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:

As accompanying drawing 1-3, a kind of switch comprises base 1 and loam cake 2, and base 1 and loam cake 2 are fastened togather by protruding button 12 and button hole 21.Switch pin 3 and button assembly 4 are installed on the base 1, and switch pin 3 is directly injection-moulded on the base 1; Be provided with operating side 5 and transfer strip 6 on button assembly 4, operating side 5 stretches out in base 1, and transfer strip 6 is provided with haptic element 61 and haptic element 62, and haptic element 61 and haptic element 62 terminations 60 are made as sheet, with the contact area of increase with switch pin 3.Shown in the figure among the embodiment sheet termination 60 be arranged to the bifurcated form.

In the present embodiment, base 1 is provided with a cylinder 11, is socketed with back-moving spring 7 on the cylinder 11, and back-moving spring 7 is a torsionspring, and a haptic element leans against on the base 1 side inwall, and another haptic element props up button assembly 4.Be provided with reference column 41 in two ends up and down near back-moving spring 7 places on button assembly 4, base 1 and loam cake 2 are provided with and reference column 41 corresponding circular holes 8.

During operation, behind the push end 5, button 5 overcomes the pressure drive transfer strip 6 of back-moving spring 7 to be passed to contact-making switch pin 3 to front slide, because the special setting of transfer strip 6 contacts more stable.Even use the back or after using under the adverse circumstances, when situation appearred getting rusty in transfer strip 6 some position, other positions still can be connected, and did not influence the normal use of switch long-term.

Because switch pin 3 is big with the contact area of transfer strip 6, switch transfer strip 6 is realized contacting with switch pin 3 with the mode of button assembly 4 with parallel passing, avoided dependence sheet metal deformation such as wane type switch to realize that the switch of contact produces the big problem of noise, even also not obvious at very quiet occasion noise.

For needs, transfer strip 6 is provided with and the corresponding haptic element of switch pin 3 quantity.

The foregoing description only is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement all should fall within the protection range of the present utility model.
