Description

Technical Field

[0001] The utility model relates to a temperature collection device, in particular to a temperature collection device for cables. Background Art

[0002] Currently, there are several main types of temperature acquisition devices on the market. One is to conduct heat to the temperature sensor through other media, and the other is to directly contact the cable under test through the temperature sensor.

[0003] The first method of conducting heat through other media is to bind the metal and the cable tightly, and then conduct the heat to the NTC resistor to collect the temperature. Due to the presence of the conductive medium, this method will cause the collected temperature to be lower than the actual temperature.

[0004] Another direct contact method is to tie the temperature sensor directly to the cable. In this method, since the temperature sensor has a water drop head and a curved contact surface, it is necessary to use insulating tape to completely wrap the temperature sensor and the cable. This installation method is not beautiful and is not convenient for disassembly. If the binding is not firm, it will also affect the accuracy of the measured data. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a temperature acquisition device for a cable includes a housing 1, a circuit board 2 and a temperature sensor 4. The housing 1 is provided with a threading hole 3 for the measured cable to pass through. The temperature acquisition device also includes a support frame 5. The temperature sensor 4 is mounted on the support frame 5 and then welded to the circuit board 2. The detection surface of the temperature sensor 4 is tangent to the inner wall of the threading hole 3.

[0029] like Figure 2 As shown, the housing 1 includes a base 11 and an upper cover 12 , and the circuit board 2 is installed on the base 11 .

[0030] like Figure 3 As shown, the upper cover 12 is provided with a groove 121 for installing the temperature sensor 4. The upper cover 12 is provided with a folding foot 122 for tying the temperature sensor 4. The device also includes a tie for tying the temperature sensor 4 and the folding foot 122, so that the tie is not easy to slip after being tied. The upper cover 12 is provided with an inclined surface 123 for facilitating the introduction of the temperature sensor 4, so that the temperature sensor is easier to enter the groove when installing the upper cover. .

[0031] like Figure 4 As shown, the support frame 5 is provided with a protrusion 51 for fixing with the circuit board 2. There are two protrusions 51. The support frame 5 is provided with an inclined mounting groove 52 for placing the pin of the temperature sensor 4. The detection surface of the temperature sensor 4 is higher than the inner wall of the threading hole 3.

[0032] The support frame 5 presses and tilts the temperature sensor so that it is tangent to the inner wall of the threading hole and slightly higher than the inner wall. The support frame 5 has two raised bumps, which are fixed to the circuit board to fix the position of the temperature sensor. The support frame 5 slightly exposes the upper surface of the temperature sensor to facilitate close contact with the cable.

[0033] The temperature sensor 4 adopts the NS1001 digital sensor, and the contact surface is a plane. The temperature sensor 4 and the support frame 5 are assembled together and then welded on the circuit board 2. The support frame 5 presses the temperature sensor 4 to press the sensor head and the threading hole, so that the detection surface of the temperature sensor 4 is tangent to the inner wall of the threading hole. Then the upper cover 12 is on the outer shell, and the temperature sensor 4 is stuck in the groove of the upper cover 12. At the same time, after the cable passes through the wire hole, the support frame and the cable in the groove are tied with a cable tie, so that it is very convenient to make the sensor in close contact.
