Description
Technical field
The present invention relates to cement resistors, more particularly to the resistance of cement seal after resistance is placed in porcelain shell
Device.
Background technique
Cement resistor generally as more high-power with being widely used, for example, as being shown in Fig. 3 and Fig. 4, by resistance
85 are placed in porcelain shell 82, are manufactured with the sealing of cement 89.2 cords of resistance 85 are connected to from the export of porcelain shell 82 in inside
(cord)87.When the cement resistor 81 is installed on mounting object object 91, also to consider that the heat for generating resistance 85 sheds
To outside, 86 face contact of metal plate installed with making the outer peripheral surface for covering cement resistor 81 in mounting object object 91 top surface,
Installation screw element 92 is set to be inserted through mounting hole 86a and metal plate 86 is fixed on mounting object object 91.
Summary of the invention
But the cement resistor 81 can not be incited somebody to action if the contact area not making metal plate 86 and porcelain shell 82 is larger
Radiating efficiency is maintained higher, so the metal plate 86 for needing flatness high, correspondingly cost also increases.
Also, other than in addition in terms of the cost the problem of, also cement resistor is required to minimize in recent years, in order to realize
Miniaturization must improve radiating efficiency.
Therefore, the present invention is made in view of the problems of the prior art point, and it is an object of the present invention to provide can be inexpensive and scattered
The cement resistor of thermal efficiency highland miniaturization.
In order to reach the purpose, the feature of cement resistor of the invention are as follows: have and be printed with thick-film resistor in inner face
Porcelain shell, filled with cement and being allowed to solidify in the porcelain shell in a manner of covering the thick-film resistor.
It according to the present invention, can be by the heat of thick-film resistor generation because the inner face in porcelain shell is printed with thick-film resistor
Directly via the outside of porcelain shell guiding porcelain shell, can efficiently radiate.Thereby, it is possible to provide low cost and high small of radiating efficiency
The cement resistor of type.
In the cement resistor, in a manner of can including one of frame member and opening to occlude the frame member
The substrate of the opening is installed on to constitute the porcelain shell, and before the substrate is installed on the frame member, by the thick film
Resistance is printed in the one side of the substrate.Thereby, it is possible to be easy to carry out the printing of thick-film resistor, and magnetic shell is simply assembled.
In the cement resistor, the thermal diffusion plate for being connected to the outer surface of the porcelain shell can be set.Thereby, it is possible into
One step improves radiating efficiency.
Further, it is possible to make the thermal diffusion plate be connected to the substrate the face for being printed with thick-film resistor opposite side face,
Radiating efficiency is further increased close to the face of thick-film resistor by enabling thermal diffusion plate to be connected to.
In the cement resistor, it can be arranged and cooperate with the porcelain shell come the support clamped to the thermal diffusion plate
Frame makes the outer surface of the porcelain shell and the thermal diffusion plate face contact, and presses the bracket to the thermal diffusion plate to make the heat
Diffuser plate and the bracket face contact.Thereby, it is possible to fully ensure the contact area of the outer surface of porcelain shell and thermal diffusion plate and heat
The contact area of diffuser plate and bracket can further increase radiating efficiency.
Such as with Shangdi, in accordance with the invention it is possible to provide the cement resistor of energy low cost and the miniaturization of radiating efficiency highland.
