The first pins are provided with a first bending portion 201 and a second bending portion 202, and the second pins are provided with a third bending portion 203.

[0025] In this embodiment, the grooved housing 1 is integrally injection-molded from pc or pe material, and an embedded seat 102 for fixing the pin body 2 is arranged inside it.

The pin body 2 is composed of 16 or 24 groups of pins, and the pins are correspondingly provided with a first bending portion 201, a second bending portion 202, and a third bending portion 203.

This structure greatly improves the stability of the pins. Among them, the inclined surface of the first bending portion 201 of the first pin contacts the grooved housing 1, and the inclined surface abuts against the grooved housing 1. After the double clamping openings of the second bending portion 202 are clamped with the clamping blocks, the stability effect of the structure is further improved. Similarly, after the inclined surface of the third bending portion 203 abuts against and clamps the third clamping block 105, the structure of the second pin is stabilized.

[0026] The first bending portion 201 has an inclined surface extending upward, and the angle of the inclined surface is 15° - 25°. One end of the second bending portion 202 is bent downward to form a "bow" - shaped structure, and the "bow" - shaped structure forms two clamping openings.

This structure is used in conjunction with the temperature detection module 101, which can detect the temperature of the connector and dissipate heat from the connector during operation, improving the usage efficiency and reliability of the connector.

[0028] Furthermore, it should be noted that the trough-shaped housing 1 and the embedded base 102 are integrally formed. The embedded base 102 includes a number of first clamping blocks 103, second clamping blocks 104, and third clamping blocks 105. The first clamping blocks 103 and the second clamping blocks 104 are respectively connected to the clamping openings of the second bending portion 202, and the third clamping block 105 is embedded in the right angle of the third bending portion 203.

The ceramic heat conduction plate 303 not only has the characteristics of a metal heat conduction plate, but also has excellent corrosion resistance and high-temperature stability. It also has characteristics such as a low coefficient of thermal expansion and high-temperature stability.

The ceramic heat conduction plate 303 is integrally formed with the aluminum alloy heat conduction plate 302.

[0033] Furthermore, it should be noted that the temperature detection module 101 includes a detection circuit and a detection probe.

[0034] The detection probe is a thermistor, which measures the temperature by generating a resistance change with the change of temperature. The circuit can determine the temperature by measuring these resistance changes.

[0035] Furthermore, it should be noted that the thickness of the aluminum alloy heat conduction plate 302 is less than the thickness of the ceramic heat conduction plate 303. The thickness of the aluminum alloy heat conduction plate 302 is 3 mm - 5 mm.
