Abstract

The utility model relates to a laminated heating apparatus circuit connector, comprising a heating pipe (1). The structure characteristic of the laminated heating apparatus circuit connector is that the utility model also comprises laminated connectors (2) arranged on the both ends of a heating wire pipe, a ceramic bushing (3), and a circuit leading out wire (4). The heading wire and the circuit leading out wire (4) of the heating pipe (1) are fixed on the connectors (2) through a pi machine, and thus, the tight contact area is formed so as to avoid the flashover phenomenon. The laminated connectors (2) are positioned in the internal cavity of the ceramic bushing (3) and connected with a power supply cord or an external connection control wire through the circuit leading out wire (4). The obvious advantage of the utility model is that the both ends of the heating pipe are provided with the laminated metal sheet connectors; therefore, the heating wire and the circuit leading out wire are contacted with the connectors fully and connected firmly with the connectors; the loosening can not happen so as to avoid the generation of the flashover. Simultaneously, the connection position between the circuit leading out wire and the power supply cord is far from the heating end; even if the heating pipe heats persistently so as to reach to the temperature of 800 DEG C, the connection between the circuit leading out wire and the power supply cord can be held in the firm and tight situation without resulting in the ageing phenomenon ahead of time and the break and loosing phenomenon.

The utility model content
The utility model technical issues that need to address, promptly the purpose of this utility model is in order to overcome existing electric oven electro-heat equipment short shortcoming in useful life, a kind of foldable type electro-heat equipment circuit connector to be provided.
The purpose of this utility model is to reach like this: foldable type electro-heat equipment circuit connector, comprise heat-generating pipe, and its design feature is: also comprise the foldable type connector, porcelain bushing and the circuit lead-out wire that are positioned at the heating conduit end; The heating line of heat-generating pipe, circuit lead-out wire together pass through hydraulic cutting presser beer jail on the foldable type connector, form tight contact area, avoid arcing; The foldable type connector is arranged in the inner chamber of porcelain bushing, is connected with power line or external control line by the circuit lead-out wire.
The purpose of this utility model also can reach by taking following measure:
The foldable type connector is one-body molded by metallic reflection plate, foldable type sheet metal connector, the heating line of heat-generating pipe enters the inner chamber of foldable type sheet metal connector by stainless steel disk metallic reflection plate center, the circuit lead-out wire enters the inner chamber of foldable type sheet metal connector, utilize hardware stamping shaping punching pin with crooked, the beer jail that folds of sheet metal part on the foldable type sheet metal connector, described heating line, circuit lead-out wire are together firmly grasped on foldable type sheet metal connector.
Heat-generating pipe is made of housing and metallic heating body, and the end line of metallic heating body passes a kaon and is connected with the foldable type connector; Described housing can be quartz ampoule, earthenware or other resistant to elevated temperatures insulating material pipes; Heating line in the described heater is rounded, square, triangle, hexagon or other polygons.
The foldable type connector uses the different metal sheet material to constitute, copper sheet for example, stainless guiding principle sheet, alloy sheet etc.
Outstanding advantage of the present utility model is:
1, outstanding advantage of the present utility model is that foldable type sheet metal connector is set at the two ends of heat-generating pipe, by simple five metals moulding punching pin (machine) circuit lead and heating line are firmly grasped in foldable type sheet metal connector metal bending tablet, the back that folds, thereby circuit lead-out wire and heating line are connected as a single entity, this beer connects mode makes heating line, circuit lead fully contact, be connected firmly with connector, therefore can not produce looseningly, can avoid the generation of arcing.Simultaneously since the circuit lead-out wire hold away from heating with the junction of power line, therefore, the ease of connection of lead-out wire and power line or other control line.
2, the utility model foldable type sheet metal connector uses simple five metals moulding punching pin, need not operation be oversimplified with butt-joint or screw, and is with low cost, is easy to produce.
3, the utility model makes the heating line (alloy wire) of different materials, circuit lead (copper product or aluminum) closely be connected with foldable type sheet metal connector by foldable type sheet metal connector, even the continuous heating up of heat-generating pipe is up to keeping fastening to 800 ℃, do not wear out and can not produce overheated doing sth. in advance, and the disconnected phenomenon of pine.
4, the utility model makes the electric heater product electro-heat equipment circuit connector can be by reaching 1000 hours uninterrupted energizing test and 10000 cycles energising life tests.
The drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment
Fig. 1 constitutes embodiment 1 of the present utility model.As can be seen from Figure 1, present embodiment is made of heat-generating pipe 1, foldable type connector 2, porcelain bushing 3, circuit lead-out wire 4 and mica sheet kaon 5.Foldable type connector 2 is positioned at the two ends of heat-generating pipe 1, and on foldable type connector 2, foldable type connector 2 is arranged in the inner chamber of porcelain bushing 3 by hydraulic cutting presser beer jail for the heating line of heat-generating pipe 1, lead-out wire 4.
As can be seen from Figure 1, foldable type connector 2 is one-body molded by metallic reflection plate 21, foldable type sheet metal connector 22, the heating line of heat-generating pipe 1 enters the inner chamber of foldable type sheet metal connector 22 by metallic reflection plate 21, lead-out wire 4 enters the inner chamber of foldable type sheet metal connector 22, by hydraulic cutting presser with described heating line, lead-out wire beer jail in stainless steel open tube 22.Heat-generating pipe 1 is made of quartz ampoule housing 11 and metallic heating body 12, and the end line of metallic heating body 12 passes a kaon 5 and is connected with foldable type connector 2.
