Abstract
The purpose of this utility model is the clamp-mounting type insulation sheet proposing a kind of easy to assembly, reliable in quality.Clamp-mounting type insulation sheet of the present utility model comprises heating wire and baffle, and described baffle has two pieces, and described heating wire is positioned in the middle of two block protection plates, and two block protection plates are fixedly connected with; The two ends of described heating wire lead to outside baffle.Clamp-mounting type insulation sheet structure of the present utility model is simple, eliminate the step of curling up heating wire on mica sheet, easily manufactured, can effectively save manpower and manufacturing cost, and can directly apply on traditional electric cooker, and without the need to improving other structure of electric cooker, improve the market competitiveness.
Description
Technical field
The utility model belongs to electrical equipment manufacturing technology field, is related specifically to a kind of insulation sheet of electric cooker.
Background technology
Present electric cooker utilizes insulation sheet to realize heat insulation function mostly, traditional insulation sheet comprises the mica wire-wrap board that electrical lead, outside jacket plates, cover plate, insulation mica panel, base plate and inside are wound with resistance wire, wherein panel, wire-wrap board, base plate are located between outside jacket plates and cover plate, the correspondence position of panel, wire-wrap board, cover plate is equipped with through hole, plug into from through hole electrical lead in the two ends of resistance wire, electrical lead is that heat-resisting stainless steel bare wire adds and wears fiberglass sleeve, is connected with electric rice cooker circuit by electric wire and terminal.Panel, cover plate, fiberglass sleeve to be worn after the resistance wire of above-mentioned insulation sheet and electrical lead are connected through winding, not only operating difficulties production efficiency is low, resistance wire is easily fractureed, and fiberglass sleeve is resistance to forces down, and adds to wear the two-layer sleeve pipe of size and also often occur withstand voltage defective phenomenon.
Summary of the invention
The purpose of this utility model is the clamp-mounting type insulation sheet proposing a kind of easy to assembly, reliable in quality.
Clamp-mounting type insulation sheet of the present utility model comprises heating wire and baffle, and described baffle has two pieces, and described heating wire is positioned in the middle of two block protection plates, and two block protection plates are fixedly connected with; The two ends of described heating wire lead to outside baffle.
Above-mentioned clamp-mounting type insulation sheet eliminates the step of curling up heating wire on mica sheet, can save manpower and cost, and enhance productivity.
Specifically, baffle has following two kinds of structures and fixed form:
1, described baffle is mica sheet, and described two killinite sheets are bonded by adhesive.During fabrication, first the side of mica sheet is coated with and spreads adhesive, then heating wire is positioned in the middle of two panels mica sheet, and draws the terminal at heating wire two ends, finally by the pressing of two panels mica sheet.
2, described baffle is ceramics, and the mode that described two pieces of ceramics are sintered by ceramics blank is fixedly connected with.During fabrication, first just heating wire is positioned in the middle of two panels ceramics blank, and draws the terminal at heating wire two ends, is finally sintered by ceramics blank, thus the two panels ceramics of sintering is fixed together.
Further, the two ends of described heating wire are drawn from same baffle place, described heating wire prebuckling, to facilitate the heating area manufacturing and increase heating wire.
Clamp-mounting type insulation sheet structure of the present utility model is simple, easily manufactured, can effectively save manpower and manufacturing cost, and can directly apply on traditional electric cooker, and without the need to improving other structure of electric cooker, improve the market competitiveness.
Accompanying drawing explanation
Fig. 1 is the sectional view of the clamp-mounting type insulation sheet of embodiment 1.
Fig. 2 is the sectional view of the clamp-mounting type insulation sheet of embodiment 2.
Accompanying drawing indicates: 1, heating wire; 2, baffle; 3, adhesive.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in Figure 1, the clamp-mounting type insulation sheet of the present embodiment comprises heating wire 1 and baffle 2, and described baffle 2 has two pieces, and described heating wire 1 is positioned in the middle of two block protection plates 2, and two block protection plates 2 are fixedly connected with; The prebuckling of described heating wire 1, the two ends of heating wire 1 lead to the outside of same baffle 2.
Above-mentioned baffle 2 is mica sheet, and described two killinite sheets are bonded by adhesive 3.During fabrication, first the side of mica sheet is coated with and spreads adhesive, then heating wire 1 is positioned in the middle of two panels mica sheet, and draws the terminal at heating wire 1 two ends, finally by the pressing of two panels mica sheet.
Above-mentioned clamp-mounting type insulation sheet eliminates the step of curling up heating wire 1 on mica sheet, can save manpower and cost, and enhance productivity.
Embodiment 1:
As shown in Figure 2, as different from Example 1, in the present embodiment, baffle 2 is ceramics, and the mode that described two pieces of ceramics are sintered by ceramics blank is fixedly connected with.During fabrication, first just heating wire 1 is positioned in the middle of two panels ceramics blank, and draws the terminal at heating wire 1 two ends, and compresses ceramics blank, is finally sintered by ceramics blank, thus the two panels ceramics of sintering is fixed together.
