Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of pin terminal formula exact constant temperature relay, comprises with the cylindrical end cap 2 of chimb 21, the shell 1 be covered on end cap 2, protrudes from the first pin terminal 3, second pin terminal 4 and ground wire terminal 5 of end cap 2 bottom.Shell 1 adopts the cut down material being easy to mould and drawing deep processing shaping, and housing oral area external-open, is configured as and is beneficial to laser welding structure.End cap 2 is metal material.
Composition graphs 3, first pin terminal 3, second pin terminal 4 is combined as a whole by glass insulator 6 with end cap 2, the top of end cap 2 is provided with a non-metal susceptor 7, the side of pedestal 7 is provided with and is provided with a fulcrum 72 higher than the boss 71 of pedestal 7 upper surface, opposite side, its inside is run through the first wire guide 73, second wire guide 74, between the boss 71 and fulcrum 72 of pedestal 7 upper surface, be provided with a pad 75, pad 75 is provided with the second contact 751.The upper surface of boss 71 is provided with an annular conductive reed 8, refer to Fig. 5 to Fig. 8, the centre of conductive reed 8 is provided with an active tongue 82, one end of active tongue 82 is unsettled, the other end is connected with conductive reed annulus body 81, the lower surface of its free end 821 is welded with the first contact 823, first contact 823 contacts with the second contact 751 that pad 75 is arranged, and using the fulcrum 72 on pedestal 7 as the strong point; The annulus body 81 relative with active tongue free end 821 is widened and perforate 83, and perforate 83 top is provided with drift angle 84.Conductive reed 8 adopts the elastomeric material conducted electricity very well to make, and annulus body 81 also forms current path while playing a supporting role.
First pin terminal 3 is through the perforate 83 of end cap 2, first wire guide 73, conductive reed 8, and its top and conductive reed 8, drift angle 84 are welded as a whole, and the second pin terminal 4 is through end cap 2, second wire guide 74, and its top and pad 75 are welded as a whole.By above-mentioned two welds, drift angle 84, conductive reed 8, pad 75 are connected conducting by pin terminal, and the pedestal 7 of middle nonmetallic materials is clamped, the active tongue 82 in the middle of conductive reed 8 is made to withstand on pedestal 7 fulcrum 72 position, this design makes drift angle 84, conductive reed 8, pad 75, pedestal 7, end cap 2 be combined into an assembly by pin terminal, pin terminal had both played the effect of ampere wires, played again the effect of connector.Stretch out the pin terminal other end outside end cap 2 and ground wire terminal 5 simultaneously, can be used as three pins is directly welded on the plug wire hole of wiring board, therefore the present invention can be installed on surface-mounted integrated circuit easily, avoids general thermostat relay in prior art and adopts screw thread, installing hole, fixed head etc. to be not suitable for the mounting means of integrated circuit.
Lower surface inside shell 1 is provided with a coign 11, tilting between coign 11 and drift angle 84, conductive reed 8 have butterfly shaped dual metal sheet 9, coign 11 and drift angle 84 interact and make butterfly shaped dual metal sheet 9 be inclined in above conductive reed 8, there is one deck flexible insulating layer 91 in butterfly shaped dual metal sheet 9 surface coverage contacted with drift angle 84, conductive reed 8, conductive reed 8, drift angle 84 and butterfly shaped dual metal sheet 9 are isolated.This design effectively make use of the cavity space of shell 1 inside, compared with the butterfly shaped dual metal sheet structure of concentric or horizontal in common thermostat relay, the bimetal leaf that this design can use diameter larger in identical space, thus relatively can have larger stroke and higher motive force, electrical property and the environmental resistances such as anti-vibration, impact such as withstand voltage, insulation can be improved.This design simultaneously can make the direct conductive reed 8 that promotes of butterfly shaped dual metal sheet 9 move, and eliminates the existence of actuator push rod, further simplified structure, conserve space.The use of flexible insulating layer 91, can play the effect of insulation, and can reduce the degree of wear of butterfly shaped dual metal sheet 9, decrease the possibility of design temperature point drift when not affecting butterfly shaped dual metal sheet 9 and being out of shape.
Described pin terminal formula exact constant temperature relay is a kind of special relay that can be automatically interrupted, and when its input temp parameter reaches certain certain value, jumping characteristic change just occurs output parameter.Main operational principle of the present invention adopts butterfly shaped dual metal sheet 9 to make temperature-sensing element, utilize butterfly shaped dual metal sheet 9 under temperature action, produce the principle of beating instantaneously, thermal coefficient of expansion again due to two panels sheet metal is different, both mutually extrude the stress promotion conductive reed 8 produced and make the rapid action of contact, thus the break-make of control circuit.Refer to Fig. 4, when temperature reaches the highest protection temperature spot of monitored device setting, butterfly shaped dual metal sheet 9 will kick overturn, flexible insulating layer 91 is driven to be out of shape together, butterfly shaped dual metal sheet 9 pushes the active tongue link 822 of conductive reed 8, and the fulcrum 72 that the active tongue free end 821 being welded with the first contact 823 provides around pedestal 7 tilts, and the first contact 823 is together lifted, first contact 823 is separated with the second contact 751, thus cuts off circuit; Refer to Fig. 3, time below the minimal protection temperature spot that temperature is reduced to monitored device setting, butterfly shaped dual metal sheet 9 again can kick again, returns to state originally, again closes between the first contact 823 and the second contact 751, thus connect circuit.The present invention can work as monitored device overheated time cut off the electricity supply, or when monitored device reaches temperature specifications requirement, temperature control is carried out to it, reaches overtemperature protection and temperature controlled object.
The present invention is the special relay being exclusively used in circuit controling temperature, integrate identification, measurement, break-make controlling functions, incorporate all basic functions of whole electron temperature-control module as single components and parts, have that working stability is reliable, long service life, volume are little, easy for installation and use advantage flexibly; As the thermostat relay of mechanical structure, there is the interference free performance far above electronic devices and components and reliability; Its pin terminal and ground wire terminal 5 can be directly welded on the plug wire hole of wiring board, solve again the problem that existing thermostat relay is not suitable for directly accessing integrated circuit.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
