Description
Technical field
The invention belongs to temperature control and electric connection technology field.
Background technology
In Chinese patent literature, the patent No. 01257602.6, name is called the utensil socket of temperature sense control structure, a temperature sense control device is wherein disclosed, this device comprises pedestal, cover on the crown cap on the pedestal, be arranged on electrode and electric connection terminal in the pedestal, at least be provided with a pair of movable contact spring and fixed touching plate between described electrode and the electric connection terminal, on pedestal, be provided with shell fragment, described shell fragment one end is fixed on the pedestal, and the other end is fixed on the crown cap by the low-melting-point metal securing member, is provided with to touch the fusing push rod that movable contact spring and fixed touching plate separate between shell fragment and movable contact spring.
Movable contact spring suppresses at fixed touching plate always under the normal condition, and both keep electric on-state.When detected object temperature surpasses design temperature, the temperature that low-melting-point metal is sensed will constantly rise, until its fusing, shell fragment will be upspring to the push rod direction this moment, drive push rod, and movable contact spring is pushed up from fixed touching plate, thereby cut off the electricity supply, play the effect that overtemperature cuts off control.The problem of its existence is: 1) shell fragment posts together by rivet (comprising the low-melting-point metal rivet) and metallic plate, shell fragment is subjected to the influence of high temperature for a long time, its elastic force can weaken gradually, cause when low-melting-point metal melts, the elastic force that discharges can not push up movable contact spring from fixed touching plate effectively.2) the low-melting-point metal rivet has lower fusing point low temperature owing to having compared with other metals, its intensity is relatively poor, easy long-term elastic force effect at shell fragment, produce stretcher strain with being under certain hot environment, it is elongated that this stretching can make low-melting-point metal extend, and causes shell fragment to be in the perk gradually of low-melting-point metal one end, and even with push rod jack-up, make movable contact spring also back down thereupon, cause loose contact easily to the direction that deviates from fixed touching plate.3) require after the low-melting-point metal melted by heat in design, the shell fragment perk promotes movable contact spring by push rod, it is separated with fixed touching plate, the elastic force that is to say shell fragment should be greater than the elastic force of movable contact spring, and on electro-contact effect, the elastic force that movable contact spring suppresses on fixed touching plate is big more, electrically contacts good more.But when the movable contact spring of design suppresses elastic force on fixed touching plate when big more, it is big that the elastic force of desired shell fragment also becomes thereupon, causes the expansion that is stretched of low-melting-point metal rivet with regard to easier like this, and when the condition of high temperature, also just loss is big more for the elastic force of shell fragment, and this is an implacable contradiction.4) be riveted between metallic plate and the shell fragment owing to the low-melting-point metal rivet, when it melts under the condition of high temperature, can be drawn back by the elastic force of shell fragment and be broken into two parts and be scattered in the pedestal, low-melting-point metal rivet after the fusing tension failure forms different shape easily, be stuck between other the charged metal parts, cause unexpected internal short-circuit, influence the fail safe of electrical equipment.
Summary of the invention
One of them purpose of the present invention is to provide the fracture that can not be stretched of a kind of low-melting-point metal, overtemperture control safety, reliable, ultra-temp controller simple in structure.
Another object of the present invention is to provide a kind of above-mentioned ultra-temp controller structure of utilizing, and realizes having the low-melting-point metal fracture that can not be stretched, overtemperture control safety, reliably, electric connector simple in structure.
For realizing first purpose of the present invention, described ultra-temp controller comprises at least one fixed touching plate and movable contact spring, described movable contact spring is arranged to self upspring and is kept isolating with fixed touching plate, be provided with on described movable contact spring and oppress its push rod that contacts with fixed touching plate, the other end of push rod withstands on the low-temperature metal spare that is fixedly arranged on the body.
Because movable contact spring is arranged to self upspring and fixed touching plate keeps isolation structure, between itself and low-temperature metal spare, be provided with push rod, this push rod is oppressed it is contacted with top contact blade, so just can utilize the elastic force of a movable contact spring, make low-temperature metal spare when being in the overtemperature fusing, push rod is separated with fixed touching plate to low-temperature metal spare direction jack-up, simple in structure.At this moment, low-temperature metal spare only is subjected to a push rod active force, can not be divided into two parts disconnects, only can produce the depressed part that a ccontaining push rod enters, and low-temperature metal spare can be extrapolated by push rod, even come off, also is the outside that is in body, can not cause with external short circuit that electrical safety is good in inside.Because the heated part of this product has only low-temperature metal spare, and has a push rod to separate between movable contact spring and the low-temperature metal spare, heat energy can not conduct to movable contact spring, and weak influence is controlled safe and reliable so the elastic force of movable contact spring can not be subjected to Yin Re.
For realizing second purpose of the present invention, described electric connector comprises patching electrode, is provided with aforesaid ultra-temp controller on the electrode described patching, and the fixed touching plate of ultra-temp controller is as its electric connecting terminal.
Because the internally charged metal parts of electric connector is more, compact conformation utilizes above-mentioned ultra-temp controller structure, and in conjunction with himself design feature, both organically can be combined.At this moment, only need be with the cancellation of the shell fragment in original technology, structure is simple relatively.The elastic force that utilizes movable contact spring self to upspring, only requiring can be with push rod jack-up when low-temperature metal spare is in molten state, because push rod self is very light, add the little by little weight metal when establishing low-temperature metal spare thereon is in molten state, this elastic force does not need very big, is easy to technically realize, requires not high yet, movable contact spring is separated with fixed touching plate, realize overtemperature outage control.Before low-temperature metal spare fusing, be added on the movable contact spring from the active force by force of push rod, it is very tight that it is contacted with fixed touching plate this, relies on many that the contact of movable contact spring self elastic force will be big compared with original technology, electrically contacts very reliable.
