Description

Sensitive switch

Technical field

The utility model relates to a kind of switching control mechanism, relates in particular to a kind of machinery and touches the sensitive switch of control.

Background technology

Sensitive switch is switched on or switched off signal or circuit as a kind of adjacent contact control element, as the usefulness of stroke detection, protection, interlocking.Sensitive switch is a kind of wink ejector half single-break electric elements, and adopting a normally closed interlock, a normally open contact and an elastic contact chip that is bearing in public great-jump-forward on the metallic support usually is moving contact.Switch jumps by make contact chip by system under external force, makes normally closed, the instantaneous changing-over of normally open contact; When external force disappeared, contact automatically reset immediately to original state.The touch structure complexity of existing sensitive switch makes its manufacturing process more complicated and cost costliness; And touch body and slide easily, misplace, overexertion makes by system easily and follows the string, and can not reset and causes malfunctioning switch, and it makes difficulty and the control effect is difficult to guarantee.

Summary of the invention

At the problem that prior art exists, technical problem to be solved in the utility model be to provide a kind of simple in structure, make easily, cost is low, the sensitive switch of easier shake-up, its long service life, the switch triggering operation is correct, sensitive.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of sensitive switch, include: spring, by the system, the drain pan end face side of being installed with tooth bar is provided with by system in the square tooth bar mesopore, outside the side of stretching out, the upper end tooth bar by system, lower end by system is goed deep in the drain pan, lower end by system is provided with spring, and an end of spring is installed on the contact C terminal, and the other end of spring is installed on the contact flat spring, the end of the end engaging contact C terminal of contact flat spring, the end away from spring of contact flat spring is provided with contact B.

Further, described contact flat spring, contact C terminal form are matrix, and the end of contact C terminal short round spring is the L type, and the outside of contact C terminal ends L type column offers U type opening, the U type opening of the end engaging contact C terminal ends of contact flat spring.

The above-mentioned lower end of going deep in the drain pan by system is convex, by the middle part of the lower end conflict spring of making.

Compared with prior art, advantage of the present utility model is to connect contact C terminal, contact flat spring respectively by the two ends of spring, touches the reliability that connector increases sensitive switch control by improving, and guarantees that the switch control procedure in time, accurately.The U type opening of the end engaging contact C terminal ends of contact flat spring, play supporting and guide effect, make contact flat spring more can correctly, reliably touch sensitive switch, can also prevent overexertion and cause the generation of following the string, can not eject phenomenon, thereby prolong the life-span of sensitive switch by system.Sensitive switch manufacturing process of the present utility model is simple, and low cost of manufacture is used extensively.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

The utility model parts comprise: contact A terminal 1, contact A 2, contact B terminal 3, contact B4, contact flat spring 5, spring 6, contact C terminal 7, square tooth bar 8, drain pan 9, press system 10.

The drain pan 9 end face side of being installed with tooth bars 8, be provided with by system 10 in side's tooth bar 8 mesopores, outside the side of stretching out, the upper end tooth bar 8 by system 10, lower end by system 10 is goed deep in the drain pan 9, lower end by system 10 is provided with spring 6, and an end of spring 6 is installed on the contact C terminal 7, and the other end of spring 6 is installed on the contact flat spring 5, the end of the end engaging contact C terminal 7 of contact flat spring 5, the end away from spring 6 of contact flat spring 5 is provided with contact B4.Contact flat spring 5, contact C terminal 7 forms are matrix (referring to Fig. 3), and the end of contact C terminal 7 short round springs 6 is the L type, and the outside of contact C terminal 7 end L type columns offers U type opening, the U type opening of end engaging contact C terminal 7 ends of contact flat spring 5.Promote spring 6 when pressing down by system 10, spring 6 drive contact flat springs 5 away from spring 6 ends to bottom offset, make conflict contact A 2 on the contact B terminal 3 of contact B4 on the contact flat spring 5, produce one time Continuity signal; When eliminating by the external force on the system 10, spring 6 drives contact flat spring 5 and resets, and the contact B4 of contact flat spring 5 restores the contact A 2 of the contact A terminal 1 of conflicting.

The lower end of going deep in the drain pan 9 by system 10 is convex (referring to Fig. 4), presses the middle part of the lower end conflict spring 6 of system 10.Contact A terminal 1 short round spring 6 ends are provided with contact A 2, and the conflict contact A 2 of contact A terminal 1 of the contact B4 on the static contact flat spring 5 down is provided with contact B terminal 3 below the contact A terminal 1, and short round spring 6 ends of contact B terminal 3 are provided with contact A 2.Contact A terminal 1 is as normally closed interlock, contact B terminal 3 is as normally open contact, and the contact flat spring 5 that is bearing in public great-jump-forward on contact C terminal 7 metallic supports is moving contact, by system 10 under external force, by contact flat spring 5 is jumped, make normally closed, the instantaneous changing-over of normally open contact; When external force disappeared, contact flat spring 5 automatically reset immediately to original state, recovered contact A 2 states of the contact B4 conflict contact A terminal 1 on the static contact flat spring 5 down.Contact A 2, contact B4 adopt sheffield plate, adopt plastic material by system 10.
