Abstract
The utility model relates to a heater, and especially relates to an embedded mica heater. The heater comprises mica sheets, resistance wires, an upper insulating layer, a lower insulating layer, and a housing. The resistance wires are winded on the mica sheets. The mica sheets are disposed between the upper insulating layer and the lower insulating layer. The mica sheets are provided with fixing grooves. The resistance wires are embedded in the fixing grooves. The number of the fixing grooves is consistent with the number of turns the resistance wires winding on the mica sheets. The heater can make the resistance wires not exposed outside, and can enhance firmness of the structure, thereby prolonging service life and saving cost.
Description
Technical field
The utility model relates to a kind of heater, especially a kind of embedded mica heater.
Background technology
The resistance wire of existing mica heater all is wrapped in mica surface, in the time of in the middle of insulating barrier is clamped in mica, because the obstruct of outstanding resistance wire, can make insulating barrier and mica produce space, not only make heater structure more fragile, and resistance wire is exposed to the open air outside, easily shorten the useful life of heater.
The utility model content
Expose outside deficiency to the open air in order to overcome existing heater resistance wire, the utility model provides a kind of embedded mica heater.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of embedded mica heater, comprise mica sheet, resistance wire, upper insulating barrier, lower insulating barrier and shell, resistance wire is wrapped on mica sheet, mica sheet is placed between insulating barrier and lower insulating barrier, and mica sheet is provided with holddown groove.
, according to another embodiment of the present utility model, comprise that further resistance wire is embedded in holddown groove.
, according to another embodiment of the present utility model, comprise that further the quantity of holddown groove is consistent with the number of turn that resistance wire is wrapped on mica sheet.
The beneficial effects of the utility model are that this heater can make resistance wire not expose to the open air outside, but also can increase the fastness of its structure, has extended useful life, has saved cost.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is a kind of structural representation of embedded mica heater;
1. mica sheets in figure, 2. resistance wire, 3. go up insulating barrier, 4. descends insulating barrier, 5. shell, 6. holddown groove.
Embodiment
It is a kind of structural representation of embedded mica heater as Fig. 1, a kind of embedded mica heater, comprise mica sheet 1, resistance wire 2, upper insulating barrier 3, lower insulating barrier 4 and shell 5, resistance wire 2 is wrapped on mica sheet 1, mica sheet 1 is placed between insulating barrier 3 and lower insulating barrier 4, mica sheet 1 is provided with holddown groove 6, and resistance wire 2 is embedded in holddown groove 6, and the quantity of holddown groove 6 is consistent with the number of turn that resistance wire 2 is wrapped on mica sheet 1.
holddown groove 6 on mica sheet 1, in the time will being wound into resistance wire 2 on mica sheet 1, resistance wire 2 all is embedded in holddown groove 6, after completing winding like this, resistance wire 2 just can not exceed the surface of mica sheet 1, and when upper insulating barrier 3 carries out clamping with 4 pairs of mica sheets of lower insulating barrier 1, just can be fitted in the surface of mica sheet 1 fully, make simultaneously resistance wire 2 be closed in holddown groove 6, thereby resistance wire and extraneous contacting have been avoided, this heater can make resistance wire not expose to the open air outside, but also can increase the fastness of its structure, extended useful life, saved cost.
