Problems solved by technology

Therefore, it takes a relatively long time for the temperature rise and fall of each temperature sensing element, the adjustment of each temperature point, and even the temperature equalization process between the temperature sensing element itself and the constant temperature medium environment. How to measure the temperature sensing elements in batches, Improving efficiency is the current technical problem that needs to be solved

Embodiment 1

[0107] The crimping terminal of the invention is used for connecting the temperature sensing elements of various sizes and specifications of the test terminal wires. refer to Figure 1 to Figure 3 , the crimp terminal 100 includes a housing 00, a push button 03 and a crimping mechanism. In this embodiment, the crimping mechanism includes a first bonding piece 05 and a second bonding piece 08, and the first bonding piece 05 and the second An openable and closable wiring port 010 is formed at the bonding place of the bonding sheet, wherein the housing 00 is formed by snapping together the surface cover 01 and the lower shell 02, and the surface cover 01 is provided with a first opening 012 and a second opening 013, The push button 03 is located in the casing and its upper part protrudes from the first opening 012 , and the connection opening 010 formed by the first bonding piece 05 and the second bonding piece 08 is located in the casing 00 and faces the second opening of the ca...

Embodiment 2

[0117] Such as Figure 6 As shown, the crimping terminal 101 of the second embodiment is modified on the basis of the crimping terminal 100 of the first embodiment, and the part with the same structure as the crimping terminal 100 of the first embodiment will not be repeated here. The crimping terminal 101 of this embodiment is different from the crimping terminal 100 of the first embodiment in that the two push button slopes 031 of the push button 03 are replaced by two push button arc surfaces 032, and the push button arc surfaces 032 are vertical If it is arranged in the direction, its contact area with the second slope 081 is relatively small (line contact). At this time, in order to prevent the deformation of the second bonding sheet 08, the second bonding sheet 08 can be thickened. Of course, the push button slope 031 of the push button 03 can also be replaced by an end surface of other shapes, as long as the end surface of the push button 03 can be in contact with the f...

Embodiment 3

[0119] Such as Figure 7 As shown, the crimping terminal 102 of the third embodiment is an improvement on the basis of the crimping terminal 100 of the first or second embodiment, and the same structure as the crimping terminal 100 of the first or second embodiment is not mentioned here. Let me repeat. The crimping terminal 102 of this embodiment differs in structure from the crimping terminal 100 of the first embodiment or the crimping terminal 101 of the second embodiment in that the elastic mechanism is a C-shaped elastic piece 18, and the C-shaped elastic piece 18 is located on the second bonding piece. 08 and the inner wall of the housing 00 ( Figure 7 At least one end of the C-shaped opening of the C-shaped elastic piece 18 is supported on the second fitting piece 08 and the C-shaped closed end surface is in contact with the inner wall of the housing 00.

[0120] When the above-mentioned crimping terminal 102 is working, if the terminal of the sensing element with the...

Abstract

The invention, which belongs to the technical field of electrical sensing element calibration, provides a multi-channel temperature inspection channel bin and a temperature calibrator. The temperaturecalibrator comprises a host with a display screen and at least one channel bin for detecting the temperature value of a temperature sensing element. The channel bin and the host are integrally and detachably assembled, and / or the channel bin is electrically connected with the host after being connected in series through a wire, and the channel bin performs data interaction with the host through awire interface. According to the invention, crimping terminal modules of the channel bin work in an inspection mode, so that automatic operation is easy to realize and the working efficiency of batchdetection is improved; the channel bin can be independently used and can also be detachably installed on the host, and use is flexible; with the using mode that the channel bins are connected into the host after being connected in series through the wires, the multi-channel temperature inspection channel bin and the temperature calibrator are particularly suitable for batch detection of temperature sensing elements with different measuring ranges or precisions in different temperature control devices, so that the detection efficiency is improved, and the detection cost is reduced.

Description

technical field [0001] The invention belongs to the electrical field and relates to a multi-channel temperature inspection channel chamber and a temperature calibrator. Background technique [0002] At present, the calibration of temperature sensing elements in the temperature measurement industry requires the temperature sensing elements to be calibrated in a specific constant temperature environment, for example, the gas medium environment of the dry body furnace, the liquid medium environment of the oil tank and the water tank, and the salt bath environment, etc.; in addition, when calibrating the temperature sensing element, it is usually necessary to measure each temperature point within the measuring range of the temperature sensing element one by one. Therefore, it takes a relatively long time for the temperature rise and fall of each temperature sensing element, the adjustment of each temperature point, and even the temperature equalization process between the temper...
