CN2264408Y - Elastic chip superthin switch - Google Patents

Abstract

The utility model relates to an elastic piece super thin switch, and two conductive pieces with different heights are arranged in the main body of the elastic piece super thin switch. The higher conductive piece is provided with a seesaw block with an elastic piece, and the front end of the seesaw block is provided with a matched button apparatus extending to the outer end of the main body. A pushing block arranged at one end of the button apparatus and matched with the seesaw elastic piece can reduce the integral height and quickly respond to rapidly open and close a connecting point.

Description

The ultra-thin switch of spring-piece type

The utility model relates to mains switch, particularly the ultra-thin switch of spring-piece type.

Construction of switch commonly used is shown in attached Figure 4 and 5, accompanying drawing 4 is exploded perspective views of mains switch commonly used, accompanying drawing 5 is textural association profiles of mains switch commonly used, be provided with in the recessed people bottom of Switch main body 1A two disconnected from each other and lead the conducting strip 2A that wears the bottom, hold joining shell fragment 3A again at a conducting strip 2A, be provided with press key pole 4A in this shell fragment 3A upper end, be provided with to closing bar 5A and spring 6A at the root edge of this press key pole 4A one end, enclosing cover 7A is placed on body 1A outer end.

When two conducting strip 2A of control make its conducting or separate, end user's pressing keys bar 4A, the supporting of this press key pole 4A root edge close that bar 5A is subjected to the effect of spring 6A and displacement in two ends of shell fragment 3A, thereby force the joining of shell fragment 3A intermediate ends in a conducting strip 2A, the shell fragment 3A other end is then with the 2A conducting of another conducting strip or separate.This structure makes shell fragment 3A and support the cooperation close bar 5A and take bigger telescopic movable space, thereby make whole height seem very big, simultaneously, support when closing bar 5A and promoted by press key pole 4A, if the action that promotes is slow slightly, then support and close also slow thereupon the moving of speed that bar 5A moves to shell fragment 3A, thereby it is also slower to make shell fragment 3A act on the speed of another conducting strip 2A, cause between shell fragment 3A and another conducting strip 2A, occurring discharge and form spark, this phenomenon often forms CR Critical infringement for some accurate facility or the big appliance chamber of the magnitude of current, even shortens greatly the life-span of switch.

The applicant finishes the utility model finally because above-mentioned mains switch shortcoming structurally reaches deeply and studied, improves.

The purpose of this utility model is: a kind of mains switch is provided, and conducting or the separation rapidly of two conducting strips of this switch, its whole height lowers, and reduces discharge and produce spark.

The purpose of this utility model is achieved in that the mains switch that is provided is the ultra-thin switch of spring-piece type, medium altitude groove one end at described Switch main body is equipped with two highly different conducting strips to the bottom, be provided with the contact that slightly protrudes in shorter conducting strip upper end, be provided with recessed draw-in groove in higher conducting strip upper end, set up at the seesaw piece at the draw-in groove end of this higher conducting strip, the abutting end with draw-in groove on the seesaw piece is provided with the recessed joining edge of its two end; At the bottom of this seesaw piece, be provided with the contact that slightly protrudes, and be provided with to be backward in this seesaw piece upper end and tiltedly stretch shape and the terminal shell fragment that is the triangle convex, above this seesaw piece, be provided with the press key pole that is mated, this press key pole front end be provided with match with seesaw piece shell fragment be the pushing block of triangle convex shape to the lower end, be provided with holder in the body outer end, be provided with spring in the press key pole outer end, be provided with the control group, be provided with enclosing cover at the body upper end cover in the press key pole upper end.

The utlity model has good result, because the conducting strip end is provided with incorporate seesaw piece and shell fragment, so can dwindle the switch whole height easily, again owing to be provided with the pushing block that cooperates with shell fragment at the press key pole front end, thereby two conducting strip conductings or separation are increased income, the phenomenon generation that reduces discharge again and produce spark, thereby, minimizing is to the infringement of facility articles for use, and switch life also can prolong.

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

Accompanying drawing 1 is the utility model switch exploded perspective view;

Combination enforcement figure when accompanying drawing 2 is the utility model conducting;

Accompanying drawing 3 is the utility model combination enforcement figure when separating with power supply;

Accompanying drawing 4 is exploded perspective views of normal mains switch;

Accompanying drawing 5 is textural association profiles of mains switch commonly used.

Attached Figure 4 and 5 had been narrated at leading portion the sixth of the twelve Earthly Branches.The corresponding relation of each parts of the utility model and its label is as follows among the accompanying drawing 1-3:

10 bodies, 11 medium altitude grooves, 12 enclosing covers, 20 conducting strips, 21 contacts, 30 conducting strips, 31 draw-in grooves, 40 seesaw pieces, 41 joining edge, 42 contacts, 43 shell fragments, 50 press key poles, 51 pushing blocks, 52 springs.

Accompanying drawing 1 is an exploded perspective view of the present utility model, from accompanying drawing 1 as seen, medium altitude groove 11 1 ends at body 10 are equipped with two highly different conducting strips 20 to the bottom, 30, be provided with the contact 21 that slightly protrudes in shorter conducting strip 20 upper ends, be provided with recessed draw-in groove 31 in higher conducting strip 30 upper ends, draw-in groove 31 ends at this higher conducting strip are erected with seesaw piece 40, abutting end with draw-in groove 31 on seesaw piece 40 is provided with the recessed joining edge 41 of its two end, be provided with the contact 42 that slightly protrudes in these seesaw piece 40 bottoms, and be provided with in these seesaw piece 40 upper ends to be backward and tiltedly stretch the shell fragment 43 that shape and its end are the triangle convex shape, above this seesaw piece 40, be provided with the press key pole 50 that is mated, be provided with the pushing block that is the triangle convex shape downwards 51 that matches with seesaw piece shell fragment 43 at these press key pole 50 front ends, be provided with holder 53 in the body outer end, be provided with spring 52 in press key pole 50 outer ends, be provided with the control group in press key pole 50 upper ends, be provided with enclosing cover 12 at the body upper end cover.

Accompanying drawing 2 and 3 is the utility model combination enforcement figure when separating when conducting and with power supply, owing to have shell fragment 43 in seesaw piece 40 upper ends and press key pole 50 front ends have pushing block 51, so, when pushing block 51 is positioned at the outer end of shell fragment 43 and higher conducting strip 30, seesaw piece 40 just promptly is pushed to shorter conducting strip 20 ends, contact 42 is contacted with contact 21, and this switch promptly is conducting state, as shown in Figure 2.When pushing block 51 is pushed the triangle convex end of getting back to shell fragment 43, shell fragment 43 is subjected to the support of the beveled edge and higher conducting strip 30 draw-in grooves 31 of triangle convex end, and is upspring immediately, and contact 42 is separated with contact 21, this switch promptly is and the power supply released state, as shown in Figure 3.Because action fast, so can prevent phenomenons such as discharge and spark really, therefore, can reduce the infringement to the facility articles for use, and increase the useful life of switch.Because seesaw piece 40 and shell fragment 43 after being integrated into, more can be simplified member, dwindle the height of switch, thereby more be applicable to the miniaturization facility that the space is less simultaneously.
