The invention discloses a heater which comprises an insulating insulator component, a front end insulator, a rear end insulator, heating wires and guide bars, wherein the insulating insulator component comprises a first insulating insulator, a second insulating insulator and a third insulating insulator; the first insulating insulator, the second insulating insulator and the third insulating insulator are sequentially connected from front to back to form a heater body; the front end insulator and the rear end insulator are arranged at the front end and the rear end of the heater body respectively; the guide bars are connected with the front end of the heater body, and connected with the heating wires; and the heating wires are arranged in the heater body, and arranged at intervals along the periphery of the heater body. The heater is simple in structure, fewer in insulating insulator and stable to use.
Description
technical field
The present invention relates to electric wire production field, refer in particular to a kind of heater.
Background technology
Existing heater insulation insulator number ratio is more, totally 13, so connecting portion is many, in practical application, junction easily produces distortion, and between insulator, fit tolerance is larger in addition, add the unsteadiness of heater strip, cause heater failure relatively more frequent, directly affect production.
summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provide a kind of structure simple, insulator is few, uses stable heater.
The technical scheme that the present invention takes is as follows: a kind of heater, comprise insulator assembly, front end insulator, rear end insulator, heater strip and lead rod, wherein, above-mentioned insulator assembly comprises the first insulator, the second insulator and the 3rd insulator, and three is in turn connected to form heater body from front to back; Above-mentioned front end insulator and rear end insulator are separately positioned on front end and the rear end of heater body; Above-mentionedly lead the front end that rod is connected to heater body, and be connected with heater strip, heater strip is arranged on heater body inside, and arranges along heater body periphery interval.
Preferably, the middle part of the first described insulator, the second insulator and the 3rd insulator is through hole, and periphery is provided with multiple groove; In above-mentioned through hole of leading in the middle part of rod insertion insulator, above-mentioned heater strip inserts in the groove of insulator periphery.
Preferably, the first described insulator, the second insulator and the 3rd insulator front end are provided with the bulge loop stretched out forward, the through-hole wall of rear end has the groove of annular, the bulge loop of rear end insulator inserts in the groove of front end insulator, front and back insulator is connected and fixed, be provided with insulation clay between two insulators, strengthen the stability connected.
Preferably, described rod of leading comprises two, and two lead rod is plugged on the 4th insulator, and is spaced apart by the 4th insulator.
Preferably, be fixedly connected with by fixed screw between described rear end insulator with the 3rd insulator.
Beneficial effect of the present invention is:
The present invention be directed to a kind of improvement opportunity scheme of prior art, The present invention reduces the quantity of insulator, all totally 3, be respectively the first insulator, the second insulator and the 3rd insulator; Thus decreasing the quantity of connecting portion, reduced tolerance simultaneously, reduces the steering range between insulator and insulator, simultaneously between insulator and insulator by the connection of the clay that insulate, enhance its steadiness, substantially increase the useful life of heater, improve production efficiency.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figures 1 to 7, the technical scheme that the present invention takes is as follows: a kind of heater, comprise insulator assembly, front end insulator 3, rear end insulator 4, heater strip 5 and lead rod 6, wherein, above-mentioned insulator assembly comprises the first insulator 1, second insulator 2 and the 3rd insulator 9, and three is in turn connected to form heater body from front to back; Above-mentioned front end insulator 3 and rear end insulator 4 are separately positioned on front end and the rear end of heater body; The above-mentioned front end of leading rod 6 and being connected to heater body, and be connected with heater strip 5, heater strip 5 is arranged on heater body inside, and arranges along heater body periphery interval.
The middle part of the first insulator 1, second insulator 2 and the 3rd insulator 9 is through hole, and periphery is provided with multiple groove; Above-mentioned rod 6 of leading inserts in the through hole in the middle part of insulator, and above-mentioned heater strip 5 inserts in the groove of insulator periphery.
First insulator 1, second insulator 2 and the 3rd insulator 9 front end are provided with the bulge loop stretched out forward, the through-hole wall of rear end has the groove of annular, the bulge loop of rear end insulator inserts in the groove of front end insulator, front and back insulator is connected and fixed, be provided with insulation clay between two insulators, strengthen the stability connected.
Lead rod 6 and comprise two, two lead rod 6 is plugged on the 4th insulator 7, and is spaced apart by the 4th insulator 7.
Be fixedly connected with by fixed screw 8 between rear end insulator 4 with the 3rd insulator 9.
Further, The present invention reduces the quantity of insulator, all totally 3, be respectively the first insulator, the second insulator and the 3rd insulator; Thus decreasing the quantity of connecting portion, reduced tolerance simultaneously, reduces the steering range between insulator and insulator, simultaneously between insulator and insulator by the connection of the clay that insulate, enhance its steadiness, substantially increase the useful life of heater, improve production efficiency.
Embodiments of the invention just introduce its embodiment, do not lie in and limit its protection range.The technical staff of the industry can make some amendment under the inspiration of the present embodiment, therefore all equivalences done according to the scope of the claims of the present invention change or modify, and all belong within the scope of Patent right requirement of the present invention.
