Abstract

The utility model relates to a reset switch, in particular to a key-press type automatic reset switch with long service life. The structure of the automatic reset switch comprises a main body and a press-button as well as a rear case. A hollow cavity is arranged in the main body. The hollow cavity is divided into a sliding chute hollow cavity which is matched with the press-button, a terminal 2 hollow cavity which is matched with a terminal 2, a terminal 1 hollow cavity which is matched with the terminal 1, and an elastic piece cavity which is used for fixing an elastic piece. The upper part of the main body is provided with a hole which is matched with a press-button handle at the upper part of the press-button; the terminal 1, the terminal 2 and a sliding press-button as well as the elastic piece playing a dialing crosspiece function are orderly fixed and arranged in the main body; the terminal 2 is provided with an electrical brush at a position near the terminal 1, and the other face is provided with a terminal elastic piece connected with the electrical brush. The reset spring of the utility model has the advantages that the press-button is automatically rebounded through the sliding chute of the main body and the elasticity of the spring, in the whole working process, a contact spring gets a slight side pressure when the press-button is pressed down, thereby achieving the effect of long service life.

Description

A kind of automatic reset switch

Technical field

The utility model relates to a kind of reset switch, refer in particular to a kind of long service life by the of bonding automatic reset switch.

Background technology

At present, known switch structure is made up of terminal contact, contact flat spring, button or push button, metal spring and shell.General switch is that switch key directly is pressed on the shell fragment, and contact flat spring passes through after hundreds and thousands of times like this, and contact flat spring can produce deformation, and such switch life is generally not long.The general life-span of this type of switch is between 5000-200000 time, such life-span is enough for general electrical equipment, but electrical equipment such as electric guitar, electronic organ key switch or the key switch of play play machine higher to some switching frequencies, their switching frequency is tens times or even hundreds of times of ordinary appliances, and 5000-200000 just is nowhere near for ten thousand times like this.

The utility model content

The utility model is at above-mentioned the deficiencies in the prior art, be intended to release a kind of long service life by the of bonding reset switch.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of automatic reset switch comprises body and button and bonnet in the structure, establish cavity in the described body, cavity is divided into the chute cavity supporting with button, with the supporting terminal II cavity of terminal II, with the supporting terminal I cavity of terminal I, and the shell fragment cavity of fixation spring tab; A hole that is complementary with the push-piece stem on button top is established on body top; Install successively in the described body terminal I and terminal II and slidably button reached the shell fragment of the shelves effect of pulling out; Described terminal II is established brush by terminal I place, and another side is established a terminal shell fragment that is connected with brush.

Establish chute in the described body, button and chute cavity are the chute structure.Establish boss on the described terminal I.

Establish the button cavity of placing spring in the described button, establish the spring seat of honour of mounting spring in the button cavity.

Conducting strip on described terminal I and the terminal II passes the jack of establishing on the bonnet respectively.

Establish the spring lower seat of mounting spring on the described bonnet; Described body links into an integrated entity with the back cover latch.

The beneficial effect of a kind of automatic reset switch of the utility model is: the utility model is to utilize the chute of button by main body, utilize the elastic force of spring and button can be rebounded automatically, be not directly by the elastic force of contact flat spring with the button pop into position, in entire work process, contact flat spring is during only with button down, be subjected to a slight lateral pressure, and terminal II is contacted with the contact point of terminal I, even the long-time high-speed work of contact flat spring so can be out of shape yet, electric property is guaranteed, thereby reach long-life effect, its life-span can reach 100-500 ten thousand times, in order to increase its feel, has increased a stainless steel shell fragment, this type of switch can be widely used in long-life electrical appliance, as: electric guitar, electronic organ key switch, the key switch of game machine.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Referring to figs. 1 through Fig. 2, the utility model is to implement like this:

A kind of automatic reset switch, comprise body 1 and button 2 and bonnet 7 in the structure, it is characterized in that: establish cavity in the described body 1, cavity is divided into the chute cavity 11 supporting with button 2, with the supporting terminal II cavity 12 of terminal II 3, with the supporting terminal I cavity 13 of terminal I4, and the shell fragment cavity 14 of fixation spring tab 5; A hole that is complementary with the push-piece stem 21 on button 2 tops is established on body 1 top; Installing terminal I4 and terminal II 3 in the described body successively reach with button 2 slidably and has pulled out the shell fragment 5 increase feels that shelves act on; Described terminal II 3 is established brush 31 by terminal I4 place, another side establish one with the sub 31 terminal shell fragments 32 that are connected of brush.

Establish chute 15 in the described body 1, button 2 is the chute structure with chute cavity 11.Establish boss 41 on the described terminal I4.Touch the button 2 downwards, button 2 moves down along chute 15, and the terminal shell fragment of establishing on the extruding terminal II3 32 suppresses drive brush 31 to a side and touches terminal I4 convex platform 41 turn-on powers, reaches and opens switching purposes; Button 2 is downwards by making spring 6 form an elastic force to lower compression simultaneously, button 2 was returned to normal state after by pressure disappeared downwards under the elastic force effect of spring 6, brush 31 is returned to normal condition and disconnects connection, is automatically reset purpose thereby reach off switch.
