Abstract
The utility model belongs to a thermocouple (thermal resistor) junction box in the field of temperature measurement instrument, which is characterized in that the junction box is axiolitic, the inner chamber is a cylinder and two cone three-step trapezoid, so the wall thickness is reduced, the material is saved, and the weight is lightened. Owing to the inner chamber is enlarged, the utility model is suitable for being provided with a spring constriction type circuit board and a temperature converter so as to be convenient for user's wire connection, a long slot is arranged on the bottom of the junction box at the same time, the connector at the end of a temperature-sensing element is inserted into the long slot, so the wring-off of thermocouple wire or platinum resistance thermometer leading wire caused by radial directional turn can be overcome.
Description
The utility model relates to the temperature measuring instrument field, has intracavity space specifically and is convenient to wiring and the fixing difficult a kind of terminal box of rotating of temperature-sensing element greatly, can be used for spraying-proof armoured thermocouple (resistance) simultaneously.
Present domestic employed thermopair (resistance) terminal box, the volume of its housing is bigger, materials are many, and inner chamber is less, can not satisfy the needs of mounting spring compression type terminal block and temperature divertor, the thermopair of An Zhuaning (resistance) temperature-sensing element rotates easily simultaneously, the lead-in wire that makes thermo wires polarity orientation difference and temperature-sensing element because of radially rotate twist disconnected.
The intracavity space that the purpose of this utility model provides terminal box is convenient to wiring greatly, can satisfy the installation of spring compression type terminal block, can be fit to simultaneously the needs that temperature divertor is installed, lead-in wire in the temperature-sensing element of armouring or thermo wires can not rupture, and the good a kind of spraying-proof thermopair (resistance) of thermo wires polarity orientation performance is used terminal box.
For finishing the technical scheme that above-mentioned purpose is taked: the terminal block housings design outline becomes Sui spherical, inner chamber is right cylinder and cone three stairsteppings, reduce wall thickness, save material and weight reduction, particularly important suitable mounting spring compression type terminal block and temperature divertor.Elongated slot is established in terminal block housings bottom, and the screw thread that is used for fixing temperature-sensing element is established in the elongated slot bottom, and with the locking screw engagement, it is big and can the temperature-sensing element fixation can not rotate to finish the terminal block housings inner chamber, overcome thermo wires or platinum resistance thermometer sensor, lead-in wire because of radially rotate twist disconnected.
The utility model embodiment is described in detail in conjunction with the accompanying drawings.
Fig. 1 is independent armouring type structural drawing for the utility model is exclusively used in;
Fig. 2 is exclusively used in the armouring fabricated construction figure of the outer protection tube of band for the utility model;
Fig. 3 is that the C of Fig. 2 is to structural drawing;
Fig. 4 is the utility model inner-cavity structure figure.
The utility model can be used for independent armouring type and promptly directly assembles armoured thermocouple (resistance) temperature-sensing element as shown in Figure 1, the profile of its box body 3 is that Sui is spherical, the radius SR62 millimeter that Sui is spherical, the radius R S46 millimeter of lid 5, inner chamber is that right cylinder JT1 and two cone JT2, JT3 form three stairsteppings, as shown in Figure 4.Establish elongated slot 12 according to the bottom of terminal block housings 3 shown in Figure 3, the distance that respectively establish between link seat screw 13, two screws 13 the step both sides of the upper end of elongated slot 12 is good with 32 millimeters.Changeable fluid temperature divertor 6 is put in the junction block upper end, above-mentioned elongated slot 12 bottoms are provided for the fixedly screw thread 10 of temperature-sensing element, the end fixture splice 7 of temperature-sensing element 9, and be inserted in elongated slot 12, packing ring 8 is established in joint 7 lower ends, and set nut 1 meshes with the screw thread 10 of terminal block housings 3 lower ends.Above-mentioned terminal box 3 and the angle between the lid 5 are 25 degree.
