Embodiment Construction

[0015] see figure 1 , shown in Fig. 2 and Fig. 3, the temperature test fixture of the present invention is suitable for fixing several probes 10, to test the temperature at some measured points on a measured object 90; This temperature test fixture comprises a substrate 20, and this substrate 20 is provided with a number of perforations 201, and the position of each perforation 201 corresponds to the position of the measured point. In this embodiment, the shape of the perforation 201 is circular; in addition, the substrate 20 can also be provided with several heating grooves 202 (The number of heating tanks 202 can be set according to actual needs, and the number of heating tanks 202 can be 0, 1, 2...). And in these through-holes 201, be respectively provided with a plurality of bearings 30, and these bearings 30 respectively comprise a set of shafts 31, these sleeve shafts 31 can move up and down in the perforation 201, and the ends of these sleeve shafts 31 are respectively ...

Abstract

The invention provides a temperature test jig, which is applied to fix a plurality of probes for testing temperature on tested points of a tested object. The temperature test jig comprises a base plate, wherein a plurality of punch holes are arranged on the base plate, a plurality of supports are respectively threaded through the punch holes, the support respectively comprises a shaft sleeve, the end portions of the shaft sleeves are respectively provided with a limiting portion, a probe is respectively fixed on the top portion of the limiting portion, and an elastic element is respectively sleeved outside the shaft sleeve, and one end of the elastic element is respectively pressed inside the liming portion, and the other end of the elastic element is respectively pressed on the surface of the base plate. The temperature test jig can fix the probes through the supports, and the tested object is pressed on the upper portion of the temperature test jig under the effect of gravity or down force when in test, and the probes are respectively corresponding to the positions of each tested point, thereby realizing the elastic contact between the probes and the tested points, in order to save the procedure of adhering the probes with hands, and increase the test efficiency.

Description

【Technical field】 [0001] The invention provides a temperature test fixture, in particular a temperature test fixture which is easy to install. 【Background technique】 [0002] In the prior art, when it is necessary to use temperature measuring probes (such as thermocouples) to measure multiple measured points of the measured object, usually the probes are directly bonded or the probes are pressed tightly on the measured points with adhesive tape. , in order to improve the connection reliability of the probe and the measured point, it is also necessary to apply thermal grease between the two; if the measured object needs additional heating, a heating block needs to use a separate fixture. If there are many measured points in the measured object, frequent replacement of the measured object, or a large number of heating blocks, this will bring the following difficulties to the operation: [0003] 1. The efficiency of bonding the probe is low, and it takes a lot of time; the pro...
