Abstract
The utility model discloses a porcelain bead used for a temperature controller comprising a porcelain bead main body (1). A center of the porcelain bead main body (1) is provided with a cylindrical-shaped lead penetrating hole (11), and two ends of the outer part of the porcelain bead main body (1) are symmetrically provided with cone-shaped parts (12). The cone-shaped parts(12) are constituted by vertical segments (121) vertical the outer periphery of the porcelain bead main body (1), arc-shaped transition segments (122), and inclined segments (123) narrowed toward two end parts of the porcelain bead main body (1). The thickness of each of the vertical segments is in a range from 1/4 to 1/3 of the wall thickness of the porcelain bead main body (1), and the length of each of the inclined segments (123) is in a range from 1/5 to 1/4 of the whole length of the porcelain bead main body (1) in an axial direction. The porcelain bead used for the temperature controller is advantageous in that the two ends of the outer parts of the porcelain bead are respectively in the shape of a cone, and therefore the installation is easy; the porcelain bead can be tripped out timely under the overvoltage and other special circumstances, and the resetting is simple.
Description
Technical field
The utility model relates to electronic ceramic product technical field, particularly a kind of thermostat porcelain bead.
Background technology
The pottery that can utilize electricity, magnetic property in electronics industry, is called electronic ceramic.Electronic ceramic is the final pottery with new function that obtains by the control of effects on surface, crystal boundary and dimensional structure.Can extensive use at aspects such as the energy, household electrical appliance, automobile and communication apparatus.
On the thermostat of the electric equipments such as water heater, need installation insurance silk or similarly install.At present, disconnected device is jumped in the fuse normally easily fusing using on these products or overvoltage.
Realizing in process of the present utility model, inventor finds that prior art at least exists following problem: after existing fuse is blown, need to change brand-new, change trouble, take time and effort.
Utility model content
In order to solve the problem of prior art, the utility model embodiment provides a kind of thermostat porcelain bead.Described technical scheme is as follows:
A kind of thermostat porcelain bead is provided, has comprised: porcelain bead body, described porcelain bead body center offers the wire inserting hole of cylinder hole shape, and the aperture of described wire inserting hole equates with the wall thickness of described porcelain bead body.
Outside two of described porcelain bead body is set to tapered portion symmetrically, described tapered portion is made up of the vertical section vertical with described porcelain bead body periphery wall, arc transition section and the tilting section to the contraction of described porcelain bead body both ends, and described arc transition section is connected smoothly with described vertical section and described tilting section.
The thickness of described vertical section is 1/4～1/3 of described porcelain bead body wall thickness, described tilting section is 1/5～1/4 of described porcelain bead body entire length in described porcelain bead body shaft length upwards, and the gradient of described tilting section is to be 15 °～25 ° angles with horizontal direction.
The radius of described arc transition section (122) equates with the thickness of described vertical section.
Further, have little chamfering on the inwall of described wire inserting hole at both ends, described little chamfering and horizontal direction are the angle of 15 °～25 °, and described little chamfering length is in the axial direction 1/4～1/3 of described wire inserting hole aperture.
Further, described thermostat is less than or equal to 5.0 by the roughness on porcelain bead surface.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
Be set to the structure of taper by this thermostat with outside two of porcelain bead, make to install easily, this thermostat in the time running into the special statuss such as overvoltage, can be jumped disconnectedly with porcelain bead in time, and resets simply.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the vertical section structure schematic diagram of the thermostat that provides of the utility model embodiment porcelain bead.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
Embodiment
The present embodiment provides a kind of thermostat porcelain bead, please refer to Fig. 1, and this thermostat comprises with porcelain bead: porcelain bead body 1, and porcelain bead body 1 center offers the wire inserting hole 11 of cylinder hole shape, and the aperture of wire inserting hole 11 equates with the wall thickness of porcelain bead body 1.Wherein, the aperture of wire inserting hole 11 is as shown in d in figure, and the wall thickness of porcelain bead body 1 is as shown in c in figure.Like this, the aperture of wire inserting hole 11 equates with the wall thickness of porcelain bead body 1, has both guaranteed the intensity of this thermostat porcelain bead, again convenient processing.
Outside two of porcelain bead body 1 is set to tapered portion 12 symmetrically, tapered portion 12 is made up of the vertical section 121 vertical with porcelain bead body 1 periphery wall, arc transition section 122 and the tilting section 123 to the 1 both ends contraction of porcelain bead body, and arc transition section 122 is connected smoothly with vertical section 121 and tilting section 123.
The thickness of vertical section 121 is 1/4～1/3 of porcelain bead body 1 wall thickness, and the length of tilting section 123 on porcelain bead body 1 is axial is 1/5～1/4 of porcelain bead body 1 entire length, and the gradient of tilting section 123 is to be 15 °～25 ° angles with horizontal direction.Wherein, the thickness of vertical section 121 is as shown in e in figure, and the length of tilting section 123 on porcelain bead body 1 is axial is as shown in a in figure, and porcelain bead body 1 entire length is as shown in b in figure.
The radius of arc transition section 122 equates with the thickness of vertical section 121.
On the inwall of wire inserting hole 11, have little chamfering 111 at both ends, little chamfering 111 is the angle of 15 °～25 ° with horizontal direction, and little chamfering 111 length is in the axial direction 1/4～1/3 of wire inserting hole 11 apertures.Wherein, little chamfering 111 length is in the axial direction as shown in h in figure.
Thermostat is less than or equal to 5.0 by the roughness on porcelain bead surface.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
