Abstract
Improve an electrothermal tube for the electric heater of terminal, comprise the terminal that metal outer pipe, flange, eduction rod, porcelain bead and stainless steel are made, eduction rod stretches out from porcelain bead, and terminal welds with eduction rod; One of described terminal has a counterbore on the surface; Also comprise silver contact, described silver contact to embed in counterbore and is fixed together, and fit with the base plate of counterbore in a surface, another is surperficial concordant with the surface of terminal or or stretch out counterbore.Owing to adopting such structure, silver contact and the copper sheet in terminal base fully contact and realize being electrically connected, and have good electric conductivity; The terminal preventing stainless steel material from making is oxidized the virtual connection or open circuit that cause, ensures the rated power of electrothermal tube.
Description
Technical field
The utility model relates to a kind of electrothermal tube of electric heater.
Background technology
Currently available technology, a kind of electrothermal tube of electric heater, comprise the terminal that metal outer pipe, flange, eduction rod, porcelain bead and stainless steel are made, eduction rod stretches out from porcelain bead, and terminal welds with eduction rod; During use, the copper sheet in terminal and terminal base is fitted.Existing problems: electric conductivity is different, movable metallic gap is large, easily causes terminal to be oxidized, and electric conductivity declines, and reaches less than rated power.
Utility model content
The purpose of this utility model is: provide a kind of electrothermal tube improving the electric heater of terminal, it can keep electric conductivity effectively, makes electrothermal tube keep rated power.
The utility model is achieved in that a kind of electrothermal tube improving the electric heater of terminal, and comprise the terminal that metal outer pipe, flange, eduction rod, porcelain bead and stainless steel are made, eduction rod stretches out from porcelain bead, and terminal welds with eduction rod; Its special character is: one of described terminal has a counterbore on the surface;
Also comprise silver contact, described silver contact to embed in counterbore and is fixed together, and fit with the base plate of counterbore in a surface, another is surperficial concordant with the surface of terminal or or stretch out counterbore.
Described a kind of electrothermal tube improving the electric heater of terminal, its special character is: described counterbore is rounded; Described silver contact is disc.
Described a kind of electrothermal tube improving the electric heater of terminal, its special character is: described counterbore is square; Described silver contact is square.
Described a kind of electrothermal tube improving the electric heater of terminal, its special character is: described silver contact is together with terminal butt-joint.。
A kind of electrothermal tube improving the electric heater of terminal of the utility model, owing to adopting such structure, silver contact and the copper sheet in terminal base fully contact and realize being electrically connected, and have good electric conductivity; The terminal preventing stainless steel material from making is oxidized the virtual connection or open circuit that cause, ensures the rated power of electrothermal tube.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
Fig. 2 is A-A view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, improve an electrothermal tube for the electric heater of terminal, comprise the terminal 6 that metal outer pipe 1, flange 2, eduction rod 3, heating wire 4, porcelain bead 5 and stainless steel are made, porcelain bead and metal outer pipe 1 are solidly connected, eduction rod 3 stretches out from porcelain bead 5, and terminal 6 welds with eduction rod 3; One of described terminal 6 has a counterbore 61 on the surface;
Also comprise silver contact 7, described silver contact 7 to embed in counterbore 61 and is fixed together, and fit with the base plate of counterbore 61 in a surface, another is surperficial concordant with the surface of terminal 6 or or stretch out counterbore.Silver contact 7 and terminal 6 are fixed together by the mode of butt-joint.
Described counterbore 61 is rounded; Described silver contact 7 is in disc.
Also can be: described counterbore 61 is square; Described silver contact 7 is square.
Above-described is only preferred embodiments of the present utility model.It should be pointed out that for the person of ordinary skill of the art, when not departing from the utility model principle, can also make some improvement and modification, this is also considered as protection range of the present utility model.
