Abstract

The invention aims to provide a temperature sensor for an electric cooker. In the temperature sensor for the electric cooker, an insulating bush and an electric wire can be gathered and bound reliably. Moreover, the temperature sensor is simple in structure and convenient to install, and the safety of the electric cooker can be enhanced greatly. The temperature sensor for the electric cooker comprises a binding wire and an aluminum cover, wherein a thermistor and a thermofuse are arranged in the aluminum cover through a bracket, are sleeved in the insulating bush respectively, and are connected with a lead which is led out of the aluminum cover respectively. Key points are that the bracket is provided with a support claw; the support claw is provided with a U-shaped clamping portion; the U-shaped clamping portion is used for clamping and fixing the insulating bush on which the thermistor and/or thermofuse is positioned; the binding wire passes through a gap between the support claw and the insulating bush, and is meshed crossly after being wrapped around the insulating bush; the two ends of the binding wire are tied together or wound firmly after being wound around the lead by at least one circle.

Description

A kind of electric cooker temperature sensor

Technical field

The present invention relates to a kind of electric cooker temperature sensor, is a kind ofly can draw reliably insulating sleeve and electric wire in tie up electric cooker temperature sensor specifically.

Background technology

At present, electric cooker temperature sensor is generally comprised of aluminium lid, thermistor, hot melt insurance, electric wire, insulating sleeve and bounding wire etc.Bounding wire draws to electric wire the center of being located at of tying up in, but, this method of tying up is just tightened up and is tied up electric wire, because casing diameter is more much larger than electric wire, so sleeve pipe does not draw in well at center, and because silica gel electric wire surface is more sliding, bundling position is in assembling, sleeve end easily slips away in use procedure, as disclosed a kind of temperature sensor that dual fail-safe is installed in " a kind of Novel rice cooker temperature sensor " (patent No. ZL2012 2 0187962.9), because sleeve pipe is more, tying up electric wire is difficult to sleeve pipe to draw in, if and tie up sleeve pipe, because sleeve pipe is tied up rear tapered cannot tightening.Consequently insulating sleeve is easily swiped with fixed head, easily causes electric cooker temperature sensor up and down dumb and insulating properties reduction.

Summary of the invention

The object of this invention is to provide a kind of electric cooker temperature sensor, this kind of electric cooker temperature sensor can draw insulating sleeve and electric wire to tie up in reliably, and simple in structure, easy for installation, the security that can significantly improve electric cooker.

Electric cooker temperature sensor of the present invention comprises bounding wire and aluminium lid, in described aluminium lid, by support, thermistor and hot melt insurance is installed, and described thermistor and hot melt insurance are placed in insulating sleeve respectively, and are connected with the wire that leads to aluminium lid outside respectively; Key is that described support is provided with support claw, described support claw is provided with U-shaped clamping section, described U-shaped clamping section is fixedly clamped the insulating sleeve at thermistor and/or hot melt insurance place, the gap of described bounding wire through support claw and insulating sleeve, and around insulating sleeve bag, hold together rear intersection and sting tightly, the end, two ends of bounding wire was mutually fastened afterwards or is closely wound around around at least one week of described wire.

Before assembling, thermistor, hot melt insurance connects respectively wire and is inserted in insulating sleeve, during assembling, for insulating sleeve and wire are banded, first by bounding wire take support claw as symmetry axis, symmetry is disposed across the inner side of support claw, and then utilize the U-shaped clamping section of support claw to be fixedly clamped the insulating sleeve at thermistor and/or hot melt insurance place, like this, the gap location of bounding wire between support claw and insulating sleeve, and clamped fixing, again bounding wire being held together to rear intersection around insulating sleeve bag subsequently stings tightly, finally being wound around wire one encloses or a few again, tie up the end of a thread and tighten up rear tight winding or tie-down.Owing to having, support claw is fixing can not be moved bounding wire, and after tying up, insulating sleeve, wire draw in firmly closely, has avoided and fixed head or the scraping of other parts.

Further, described support comprises inner support and support arm, and described thermistor is fixed on aluminium lid inner top by inner support, and the lower position of thermistor is fixed in described hot melt insurance by support arm; Described inner support and/or support arm are provided with support claw.Can maximally utilise like this space in electric cooker temperature sensor, reduce thermistor, hot melt insurance area occupied, thereby reduce the volume of electric cooker temperature sensor.

Further, described support and support claw one form, to facilitate processing and manufacturing.

Electric cooker temperature sensor of the present invention is provided with support claw structure, the position of bounding wire can be fixed, and insulating sleeve, wire can be drawn in reliably fixing, can slide displacement, improved the security reliability of electric cooker.

The specific embodiment

Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as the effect of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part and operation principle etc.

Embodiment 1:

As shown in Figure 1, 2, 3, the electric cooker temperature sensor of the present embodiment comprises bounding wire 1 and aluminium lid 2, in described aluminium lid 2, by support, thermistor 3 and hot melt insurance 4 are installed, described support comprises inner support 5 and support arm 6, described thermistor 3 is fixed on aluminium lid 2 inner tops by inner support 5, and the lower position of thermistor 3 is fixed in described hot melt insurance 4 by support arm 6;

Described thermistor 3 is placed in the first insulating sleeve 7, and be connected with the first wire 8 that leads to aluminium lid 2 outsides, described hot melt insurance 4 is placed in the second insulating sleeve 9, and be connected with the second wire 10 that leads to aluminium lid 2 outsides, support arm 6 is integrally formed with a downward outstanding support claw 11, it is that T-shaped sheet material is made that this support claw 11 adopts sawing sheet, the horizontal level of T-shaped bottom forms a U-shaped clamping section 12, and described U-shaped clamping section 12 is fixedly clamped first insulating sleeve 7 at thermistor 3 places;

The gap of bounding wire 1 through support claw 11 and the second insulating sleeve 9, and hold together rear intersection around the first insulating sleeve 7, the second insulating sleeve 9 bags and sting tightly, the end, two ends of bounding wire 1 is around the first wire 8, closely winding after second 10 several weeks of wire.

Before assembling, thermistor 3, hot melt insurance 4 connects respectively corresponding wire and is inserted in corresponding insulating sleeve, during assembling, for insulating sleeve and wire are banded, first bounding wire 1 is disposed across to the inner side of support claw 11, and then utilize the U-shaped clamping section 12 of support claw 11 to be fixedly clamped first insulating sleeve 7 at thermistor 3 places, like this, the gap location of bounding wire 1 between support claw 11 and the first insulating sleeve 7, and clamped fixing, subsequently again by bounding wire 1 around the first insulating sleeve 7, the second insulating sleeve 9 bags hold together rear intersection and sting tightly, finally be wound around again the first wire 8, the second wire 10 a few, 1 of bounding wire tightens up rear tight winding.Bounding wire 1 is because supported pawl is fixed, so can not move, after tying up, insulating sleeve, wire draw in firmly closely, has avoided and fixed head or the scraping of other parts.
