Description
Technical field
This utility model relates to the parts of a kind of electric heater, specifically a kind of electric heater terminal structure.
Background technology
In the heating occasion that high temperature, high pressure or corrosivity are the strongest, generally employing electric heating tube is as heating element heater, owing to electric heating tube shell is not charged, therefore without considering the Insulation Problems of electric heating tube and container casing.But the use of electric heating tube still suffers from defect: 1, structure is complicated, and not only space hold is relatively big, and manufacturing cost is high；2, corrosion resistance is poor, and service life is short, and safety is the best；3, heater is not directly contacted with heated medium, and the thermal efficiency is relatively low.If in order to improve the thermal efficiency, reduce cost and directly use resistive element as electrical heating elements, being difficult to the insulated enclosure connectivity problem solving electrical heating elements with container casing.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of compact conformation, easily manufactured, low cost, safety is good, the thermal efficiency is high electric heater terminal structure.
In order to solve above-mentioned technical problem; electric heater terminal structure of the present utility model; including the contact rod of exit being connected to heater and the protection metal pipe being welded on heater housings; the upper end of protection metal pipe is provided with rosette; contact rod is through protection metal pipe and extend into rosette interior formation terminals; ceramic insulating tube it is provided with between contact rod and protection metal pipe; the upper end of protection metal pipe be welded be positioned at rosette there is externally threaded contiguous block; it is rotary with clamp nut on contiguous block, there is between contact rod and clamp nut gap.
Being welded with the compact heap being enclosed within contact rod on described contact rod, described compact heap is positioned at clamp nut, is mounted with sealing gasket, is provided with lower seal pad between described compact heap and the upper surface of contiguous block between described compact heap and the inner face of clamp nut.
The upper end of described contact rod is provided with threaded section, described threaded section is rotary with clamp nut, is provided with insulated enclosure circle between described clamp nut and clamp nut.
Described upper sealing gasket has the insulation sleeve that one section of bore section to clamp nut top extends, and this insulation sleeve extend between clamp nut and contact rod；Described lower seal pad has one section of insulation sleeve extended below clamp nut, and this insulation sleeve extend between contiguous block and contact rod.
After using above-mentioned structure; due to the contiguous block arranged in the ceramic insulating tube arranged between contact rod and protection metal pipe and rosette and clamp nut and there is between contact rod and clamp nut gap; thus contact rod is thoroughly separated with protection metal pipe and clamp nut; it is not in contact with each other mutually; thus ensure that security performance; its reasonable in design is compact; greatly reduce taking of space; it is simultaneously connected with between block and clamp nut the sealing structure arranged, further ensures its security reliability.

Fig. 1 is the structural representation of this utility model electric heater terminal structure.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, electric heater terminal structure of the present utility model is described in further detail.
nullAs shown in the figure，Electric heater terminal structure of the present utility model，Including the contact rod 1 of exit being connected to heater and the protection metal pipe 2 being welded on heater housings，The upper end of protection metal pipe 2 is provided with rosette 3，Contact rod 1 is through protection metal pipe 2 and extend into rosette 3 interior formation terminals，Ceramic insulating tube 4 it is provided with between contact rod 1 and protection metal pipe 2，The upper end of protection metal pipe 2 be welded be positioned at rosette there is externally threaded contiguous block 5，Clamp nut 6 it is rotary with on contiguous block 5，Between contact rod 4 and clamp nut 6, there is gap，Wherein，The compact heap 7 being enclosed within contact rod also it is welded with on contact rod 1，Compact heap 7 is positioned at clamp nut，Sealing gasket 8 it is mounted with between the inner face of compact heap 7 and clamp nut 6，Lower seal pad 9 it is provided with between the upper surface of compact heap 7 and contiguous block 5，Upper sealing gasket 8 has the insulation sleeve that one section of bore section to clamp nut top extends，This insulation sleeve extend between clamp nut 6 and contact rod 1；Lower seal pad 9 has one section of insulation sleeve extended below clamp nut, and this insulation sleeve extend between contiguous block 5 and contact rod 1.
Further, the upper end of described contact rod 1 is provided with threaded section, and threaded section is rotary with clamp nut 10, is provided with insulated enclosure circle 11, thus further increases the reliability of sealing between clamp nut 10 and clamp nut 6.
