Abstract

The utility model discloses a kind of mica heating plate, the mica substrate and the pressing that include a rectangle are fixed on two lip-deep two groups of heating wires of mica substrate, the end of heating wire connects pad, mica substrate is positioned at pad locations and offers the through hole passing through for scolding tin, and the pad on mica substrate two sides is electrically connected by scolding tin; Described pad is positioned at a vertex position of mica substrate, and described heating wire is arranged along mica substrate length direction is roundabout, and the other end of heating wire turns back and is connected with pad along other three summits of mica substrate; Every group of described heating wire includes three that are arranged in parallel; By all arrange heating wire on the two sides of mica substrate, caloric value is large, and heating wire has adopted rational arrangement, make the gap between heating wire little, the space availability ratio of mica substrate is high, and in the situation that mica substrate area is certain, the length of heating wire is relatively long, and the sectional area of heating wire is larger, the heating power of heating wire is higher like this.

Description

A kind of mica heating plate

Technical field

The utility model belongs to electric heating accessory field, is specifically related to the structure of mica heating plate.

Background technology

Existing mica heater be all generally by heating wire uniform winding on micarex, using micarex as supporting and insulator, its deficiency is that the volume ratio of whole heater is larger, needs larger installing space, make the overall volume of heating or drying plant larger, result of use is undesirable.

Summary of the invention

Technical problem to be solved in the utility model is: the deficiency existing for prior art, provides a kind of compact conformation, the mica heating plate that volume is little.

For realizing the object of the utility model, be achieved by the following technical solutions: a kind of mica heating plate, the mica substrate and the pressing that include a rectangle are fixed on two lip-deep two groups of heating wires of mica substrate, the end of heating wire connects pad, mica substrate is positioned at pad locations and offers the through hole passing through for scolding tin, and the pad on mica substrate two sides is electrically connected by scolding tin; Described pad is positioned at a vertex position of mica substrate, and described heating wire is arranged along mica substrate length direction is roundabout, and the other end of heating wire turns back and is connected with pad along other three summits of mica substrate; Every group of described heating wire includes three that are arranged in parallel; The width of every heating wire is 6.5mm, and the external corner side of heating wire crooked place is with the round-corner transition of radius 6.5mm, and inner corner trim side is with the round-corner transition of radius 0.8mm; The distance of adjacent two heating wires is 4mm; The length of described mica substrate is 590mm, and width is 510mm; On described mica substrate, start there is connecting hole near minor face marginal position.

Compared with prior art, the beneficial effects of the utility model are: by all arrange heating wire on the two sides of mica substrate, caloric value is large, and heating wire adopted rational arrangement, makes the gap between heating wire little, the space availability ratio of mica substrate is high, in the situation that mica substrate area is certain, the length of heating wire is relatively long, and the sectional area of heating wire is larger, the heating power of heating wire is higher like this, and the scope of application is wide.Spacing between described heating wire is suitable, has both ensured that the area of mica substrate is less, and has not produced short circuit between adjacent heating wire, and inductor loss is less.

Embodiment

With reference to the accompanying drawings embodiment of the present utility model is made a detailed explanation below.

According to shown in Fig. 1 to Fig. 2, a kind of mica heating plate described in the present embodiment, the mica substrate 1 and the pressing that include a rectangle are fixed on two lip-deep two groups of heating wires 3 of mica substrate, the end of heating wire connects pad 2, mica substrate is positioned at pad locations and offers the through hole 21 passing through for scolding tin, and the pad on mica substrate two sides is electrically connected by scolding tin; Described pad is positioned at a vertex position of mica substrate, and described heating wire is arranged along mica substrate length direction is roundabout, and the other end of heating wire turns back and is connected with pad along other three summits of mica substrate; Every group of described heating wire includes three that are arranged in parallel; The width of every heating wire is 6.5mm, and the external corner side of heating wire crooked place is with the round-corner transition of radius 6.5mm, and inner corner trim side is with the round-corner transition of radius 0.8mm; The distance of adjacent two heating wires is 4mm; The length of described mica substrate is 590mm, and width is 510mm; On described mica substrate, start to have connecting hole 11 near minor face marginal position.

By all arrange heating wire on the two sides of mica substrate, caloric value is large, and heating wire has adopted rational arrangement, make the gap between heating wire little, the space availability ratio of mica substrate is high, in the situation that mica substrate area is certain, the length of heating wire is relatively long, and the sectional area of heating wire is larger, the heating power of heating wire is higher like this, and the scope of application is wide.Spacing between described heating wire is suitable, has both ensured that the area of mica substrate is less, and has not produced short circuit between adjacent heating wire, and inductor loss is less.
