Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2; the utility model embodiment provides a kind of temperature controller with temperature and current protecting function; comprise the reed up and down 1 and the fixed touching plate 2 that cooperatively interact and install; the vertical direction of described upper and lower reed 1 is provided with bimetal leaf 3; the end of described upper and lower reed 1 and bimetal leaf 3 is connected by vertical connector 4; described upper and lower reed 1 can promote and be switched on or switched off with fixed touching plate 2 by hard to bear bimetal leaf 3; described upper and lower reed 1 is connected with the first terminal 5, and described fixed touching plate 2 is connected with the second terminal 6 by current protective device.
The utility model by arranging current protective device between described fixed touching plate 2 and the second terminal 6; can be temperature controller the second protection based on overcurrent is provided, once trigger second protection, even if overcurrent condition disappears; temperature controller also can not reclose, and ensures the use safety of electrical equipment.
According to the utility model the first embodiment; described current protective device is upper shell fragment 71 and the lower shell fragment 72 being connected with fixed touching plate 2 and the second terminal 6 respectively; the end of described upper shell fragment 71 and lower shell fragment 72 have make they mutually away from elastic force, the end of described upper shell fragment 71 and lower shell fragment 72 by scolding tin 73 bonding.
It should be noted that, by controlling size and the fusing point of scolding tin 73, that can control shell fragment 71 and lower shell fragment 72 flicks temperature and electric current, and manufacturing enterprise can select flexibly according to the parameter of product, applied widely, with low cost, safe and reliable. Because upper shell fragment 71 and lower shell fragment 72 self have elasticity; after its scolding tin 73 fusing, will inevitably flick; it is the secondary protector under abnormality as temperature controller; when in the face of large dust, large electric current or hot environment; it has avoided being attracted because electric current is excessive, and cause cannot disjunction; also avoided causing mechanical disjunction mechanism to move because of large dust, prevented that temperature controller from continuing connection and causing apparatus failure under abnormality.
Preferably, described upper shell fragment 71 and lower shell fragment 72 and the connecting portion of fixed touching plate 2 and the second terminal 6 and by the bonding bonding part of scolding tin 73 between be provided with symmetrical bandy curved portions 74. Described upper shell fragment 71 and lower shell fragment 72 and fixed touching plate 2 and the connecting portion of the second terminal 6 between be provided with insulating concrete mica plate 75.
It should be noted that, described insulating concrete mica plate 75 makes described upper shell fragment 71 and lower shell fragment 72 except all electricity isolation of the position by the bonding bonding part of scolding tin 73, there is the length at elastically-deformable position in described curved portions 74, makes it still have in a long time elasticity for promoting described upper shell fragment 71 and lower shell fragment 72.
In conjunction with Fig. 3 and Fig. 4, according to the utility model the second embodiment, be with the first embodiment difference, described current protective device is the current-limiting fuse 76 that connects fixed touching plate 2 and the second terminal 6.
Specifically, described current-limiting fuse 76 is common Fuse Type fuse, and in the time that the electric current passing through is larger, current-limiting fuse 76 produces larger heat, and causes self fusing, cuts off circuit connect with this.
Preferably, described fixed touching plate 2 and the second terminal 6 are connected with respectively the first brace 77 at an angle to each other and the second brace 78, and described current protective device connects described the first brace 77 and the second brace 78. Because the bimetal leaf 3 of temperature controller is tested by the temperature of electricity measurer for accurate, therefore it is general near testee. And current protective device is measured the bulk temperature of temperature controller and the electric current flowing through; it should avoid the direct impact of testee; therefore described the first brace 77 and the second brace 78 dorsad the bimetal leaf 3 of described temperature controller arrange, the angular range of described the first brace 77 and the second brace 78 is 10-160 degree. In this angular range, on the one hand can be to greatest extent away from testee, be also that the fusing of fuse leaves sufficient space on the other hand, the disjunction of guarantee insurance silk fusing after-current. Described the first brace 77 and the second brace 78 are at an angle to each other, produce the possibility of electric arc while also having reduced blown fuse.
For the ease of installation and the replacing of above-mentioned fuse, the end of described the first brace 77 and the second brace 78 is curled and is formed splicing ear 79, and described current protective device is plugged in described splicing ear 79. Because described splicing ear 79 is that described the first brace 77 and the second brace 78 are curled formation, thicker than other place, under high temperature or large electric current environment, can also keep good contact with being connected of fuse, guarantee insurance silk can play reliable disjunction effect.
Preferably, the top of described temperature controller is provided with pressing plate 8, and described pressing plate 8 is provided with adjusting rod 9, and described adjusting rod 9 lower ends are provided with ceramic push rod 10, described ceramic push rod 10 and described upper and lower reed 1 butt. Described adjusting rod 9, by rotating up and down relative to pressing plate 8, promotes upper and lower reed 1 by ceramic push rod 10, regulates the break-make temperature of temperature controller. Wherein, described vertical connector 4 is ceramic connecting rod. Described ceramic connecting rod has the performance of partiting thermal insulation, can reduce the temperature impact of upper and lower reed 1 on bimetal leaf 3.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
