Technical field
The utility model relates to a kind of electro-heat equipment, particularly a kind of foldable type electro-heat equipment circuit connector that is applicable to electro-heat equipment.Be suitable for electric heater products such as electric oven, belong to electric heater product accessories technical field.
Background technology
At present, electric heating appliance products such as electric oven are quick, clean, sanitary and very popular with it, and this class electric heater product has entered in thousands upon thousands families.In the prior art, the electro-heat equipment in the electric oven particularly, because the leading-out end line of heat-generating pipe is general direct with the power line hinge joint or lead to screw and power line is fixed on the exit of heat-generating pipe, these two kinds of syndetons cause the junction contact area little, because physical characteristic can produce the arcing phenomenon, thereby cause roll line and send high temperature, therefore, the junction will produce loosening after using one period short time, can fuse the bonding pad afterwards through repeatability energising/outage, cause electro-heat equipment short useful life, increase user's use cost, bring many troubles to the user.
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.
As can be seen from Figure 1, foldable type sheet metal connector 22 is provided with brace flexible, that fold, by crooked, the described brace that folds, can make circuit lead-out wire 4 and heating line and connector 22 connect into an integral body, can not produce looseningly, avoids straight fiery phenomenon.
In the present embodiment: described kaon 5 is the mica sheet plectane.Described lead-out wire 4 is made of metal core wire and fibrous covering or plastic insulating layer, and metal core wire is copper cash, albronze line or other alloy wire.Described housing 11 can be quartz ampoule, earthenware or other resistant to elevated temperatures insulating material pipes; Heating line in the described heater 12 is rounded, square, triangle, hexagon or other polygons.
Because the heat energy that the heating line of heat-generating pipe 1 produces can shed to two-port, covers mica sheet kaon 5 in two-port, and the reflecting plate on the foldable type connector 2 can reduce heat energy and leak, and avoids making circuit lead-out wire 4 to bring out now overheated and the premature aging phenomenon.
As can be seen from Figure 2, the characteristics of the utility model embodiment 2 are: an insulating sleeve 6 is set on the lead-out wire 4.All the other are with embodiment 1.
