Problems solved by technology

[0002] The temperature measurement fixture in the related art holds a piece of PTC (Positive Temperature Coefficient, positive temperature coefficient) core body, and conducts a power-on test on the exposed positive and negative electrodes of the power supply led by the fixture. The number of temperature measurement products can only be one. And when the temperature is measured, the positive and negative poles are exposed, which is very easy to cause electric shock

Embodiment Construction

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0031] Refer below Figure 1-Figure 5 A jig 10 for measuring the temperature of the PTC core 6 according to an embodiment of the present invention is described. Here, it should be noted that since the base part of the PTC core 6 is made of ceramic material, and only the two largest opposite sides have aluminum powder, the aluminum powder surface of the PTC core 6 can be energized as an electrode when testing.

[0032] like figure 1 As shown, the fixture 10 for measuring the temperature of the PTC core 6 according to the embodim...

Abstract

The invention discloses a fixture for measuring the temperature of a PTC core. The fixture for measuring the temperature of a PTC core includes: an insulating positioning component, and the insulating positioning component has a plurality of core positioning components arranged at intervals. slot, the core positioning groove is suitable for placing the PTC core; the positive test assembly, the positive test assembly is arranged on the insulation positioning assembly, and the positive test assembly includes a plurality of positive detection parts; the negative test assembly, the The negative test component is arranged on the insulation positioning component, the negative test component is electrically isolated from the positive test component, and the negative test component includes a plurality of negative detection parts, wherein the negative detection part and the The anode detection part is opposite to the core positioning groove and is respectively used to connect the positive electrode and the negative electrode of the PTC core placed in the core positioning groove. According to the jig for temperature measurement of PTC cores of the present invention, multiple PTC cores can be tested simultaneously, and the testing efficiency of PTC cores is improved.

Description

technical field [0001] The invention relates to the technical field of core detection, in particular to a fixture for temperature measurement of a PTC core. Background technique [0002] The temperature measurement fixture in the related art holds a piece of PTC (Positive Temperature Coefficient, positive temperature coefficient) core body, and conducts a power-on test on the exposed positive and negative electrodes of the power supply led by the fixture. The number of temperature measurement products can only be one. Moreover, the positive and negative poles are exposed during temperature measurement, which is very prone to electric shock. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a fixture for temperature measurement of PTC cores, the fixture for temperature measurement of PTC cores can test multiple PTC cores at the same time, improvi...
