Abstract
The utility model relates to a three-reed microswitch, comprising a shell base and a shell cover, wherein a common terminal slot, a normally open terminal slot and a normally closed terminal slot are arranged at the bottom of the shell base; a common terminal, a normally open terminal and a normally closed terminal are respectively arranged inside the common terminal slot, the normally open terminal slot and the normally closed terminal slot; the common terminal extends to one end inside a movable slot and is connected with the top end of the movable slot; the normally open terminal extends to one end inside the movable slot and is opposite to the end inside the movable slot to which the normally closed terminal extends; a moving slot is arranged on the common terminal; a movable reed is inserted into the moving slot in a penetrating manner; the movable reed is connected with the common terminal through a leaf spring, and an auxiliary spring is arranged between the movable reed and the beam of the common terminal. The three-reed microswitch has the beneficial effects that the operating force and resilience force of the microswitch are increased, and meanwhile, when the microswitch is used, the phenomenon that a button does not rebound due to sticking or the fact that a movable contact and a normally open terminal contact are fused and not separated is also avoided.
Description
Technical field
The utility model relates to a kind of sensitive switch, especially relates to a kind of three reed-type sensitive switches.
Background technology
Sensitive switch is a kind of quick converting switch of exerting pressure and actuating, because the contact spacing of its switch is smaller, therefore named sensitive switch is again sensitive switch.Its operation principle is: outer mechanical force is used for the action reed by actuated element (push-piece, button, lever, roller etc.) with masterpiece, when the action reed is displaced to critical point, produce instantaneous operation, make moving contact and fixed contact quick-make or the disconnection of action reed end.After the active force on the actuated element was removed, the action reed produced counteragent power, reach the action critical point of reed when the actuated element reverse stroke after, the instantaneous counteragent of finishing.The main flow sensitive switch of existing market has two kinds, and a kind of is the double-reed moving switch that declines, and the actuating mechanism of switch is to realize that by two flat springs the circuit of switch switches; Another kind is the Extension Spring-type sensitive switch, and the actuating mechanism of switch is to realize that by a columnar extension spring circuit of switch switches.All there is following problems in use in these two kinds of sensitive switches: operating physical force can not be too large when 1, using, but can make the movable contact spring distortion after too large.2, because but movable contact spring only depends on flat spring to realize compressing and recovering, so that flat spring damages when long-term the use easily, useful life is short.Because independent flat spring self resilience force is less, can't prevent effectively that 3, not separating with the fusion of Chang Kaiduan contact and causing the phenomenon of not resilience of button to occur from appearring in moving contact in charged course of action.4, differential movement is larger, and control precision is not high.
The utility model content
The purpose of this utility model provides a kind of three reed-type sensitive switches, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of three reed-type sensitive switches, comprise package header and the shell lid that is arranged at the package header end face, the top middle portion of described package header is provided with the button groove near the left end place, be provided with button in the button groove, the bottom of package header is provided with common terminal groove from left to right successively, Chang Kaiduan pilot trench and normal-closed end pilot trench, common terminal groove, Chang Kaiduan pilot trench and normal-closed end pilot trench all are connected with the loose slot that is arranged at the package header middle part, described common terminal groove, be respectively equipped with common terminal in Chang Kaiduan pilot trench and the normal-closed end pilot trench, Chang Kaiduan and normally closed terminal, common terminal, one end of Chang Kaiduan and normally closed terminal all extends to the outside of package header, common terminal, the other end of Chang Kaiduan and normally closed terminal all extends in the loose slot, the end that described common terminal extends in the loose slot is connected with the top of loose slot, end in Chang Kaiduan extends to the interior end of loose slot and normally closed terminal extends to loose slot is relative, described common terminal is provided with shifting chute, but be interspersed with movable contact spring in this shifting chute, but movable contact spring passes through together go side sub-connection of flat spring, and but the right-hand member of movable contact spring extends between the Chang Kaiduan end relative with normally closed terminal, but the contact of movable contact spring and button bottom is connected, but described movable contact spring is provided with secondary spring between the crossbeam of go side together.
The beneficial effects of the utility model are: the operating physical force and the resilience force that have increased sensitive switch, dwindled the differential movement of sensitive switch, improved the control precision of sensitive switch, avoided sensitive switch in use, stuck or moving contact and Chang Kaiduan contact occur and merge and do not separate the phenomenon that causes not resilience of button and occur, also prolonged simultaneously the useful life of flat spring.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the overall structure end view of the described a kind of three reed-type sensitive switches of the utility model embodiment;
Fig. 2 is the structural representation of the described package header of the utility model embodiment.
Among the figure:
1, package header; 2, shell lid; 3, button groove; 4, button; 5, common terminal groove; 6, Chang Kaiduan pilot trench; 7, normal-closed end pilot trench; 8, loose slot; 9, common terminal; 10, Chang Kaiduan; 11, normally closed terminal; But 12 movable contact springs; 13, flat spring; 14, secondary spring.
Embodiment
Shown in Fig. 1-2, the described a kind of three reed-type sensitive switches of the utility model embodiment, comprise package header 1 and the shell lid 2 that is arranged at package header 1 end face, the top middle portion of described package header 1 is provided with button groove 3 near the left end place, be provided with button 4 in the button groove 3, the bottom of package header 1 is provided with common terminal groove 5 from left to right successively, Chang Kaiduan pilot trench 6 and normal-closed end pilot trench 7, common terminal groove 5, Chang Kaiduan pilot trench 6 and normal-closed end pilot trench 7 all are connected with the loose slot 8 that is arranged at package header 1 middle part, described common terminal groove 5, be respectively equipped with common terminal 9 in Chang Kaiduan pilot trench 6 and the normal-closed end pilot trench 7, Chang Kaiduan 10 and normally closed terminal 11, common terminal 9, one end of Chang Kaiduan 10 and normally closed terminal 11 all extends to the outside of package header 1, common terminal 9, the other end of Chang Kaiduan 10 and normally closed terminal 11 all extends in the loose slot 8, the end that described common terminal 9 extends in the loose slot 8 is connected with the top of loose slot 8, Chang Kaiduan 10 extends to a end and normally closed terminal 11 in the loose slot 8, and to extend to the interior end of loose slot 8 relative, described common terminal 9 is provided with shifting chute, but be interspersed with movable contact spring 12 in this shifting chute, but movable contact spring 12 is by together go side 9 connections of flat spring 13, and but the right-hand member of movable contact spring 12 extends between the relative end of Chang Kaiduan 10 and normally closed terminal 11, but the contact of the bottom of movable contact spring 12 and button 4 is connected, but described movable contact spring 12 is provided with secondary spring 14 between the crossbeam of go side 9 together.
