Description

Technical Field

[0001] The utility model relates to the technical field of sensor resistance detection, in particular to a sensor resistance detection device. Background Art

[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. The main component of the sensor is the resistor, and the sensor resistor needs to be tested during production.

[0003] The position for installing the resistor pin on the existing resistor detection device is located on the outer wall of the device, and the installation position is fixed. After the resistor pin is inserted into the slot at the installation position, the bolt on the side wall of the slot is used to tighten the pin to achieve fixation, which makes the installation and detachability of the resistor more troublesome. Secondly, since the slot position is fixed, when detecting resistors with different pin widths, it is necessary to bend the pin so that the pin can be inserted into the slot, which will affect the detection efficiency. In addition, the existing detection device can only detect resistors at room temperature, and cannot detect the influence of temperature on resistors, and the detection range is relatively limited. Therefore, the utility model proposes a sensor resistance detection device. Utility Model Content

A display and control buttons are installed on the surface of the detector, an electric heating wire is fixed on the top wall inside the top cover, and a refrigeration component is installed on the top wall of the top cover and on the side away from the electric heating wire.

[0006] Furthermore, the top cover is designed to be open on one side close to the display, and the inside of the top cover opening is rotatably connected to two side doors via hinges.

[0021] 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 only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 3 As shown, it relates to a sensor resistance detection device, including a detector 1, a top cover 2 is fixed on the upper surface of the detector 1, a guide seat 3 is fixed on the top of the detector 1 and located inside the top cover 2, a slide groove 4 is opened on the upper surface of the guide seat 3, two sliders 5 are slidably connected inside the slide groove 4, and pin fixing components 6 are fixed on the top of the two sliders 5. A two-way screw rod 7 is rotatably connected inside the slide groove 4, and the two-way screw rod 7 passes through the two sliders 5 and is threadedly rotatably connected to the two sliders 5. A display 9 and a control button 16 are installed on the surface of the detector 1, an electric heating wire 10 is fixed on the inner top wall of the top cover 2, and a refrigeration component is installed on the top wall of the top cover 2 and on the side away from the electric heating wire 10.

[0023] In this embodiment, the detector 1 and the display 9 are both existing technologies. The display 9 is connected to the detector 1 and the detector 1 can be controlled to work via the display 9 .

[0024] like Figure 1 As shown, the side of the top cover 2 close to the display 9 is designed to be open, and the inside of the open top cover 2 is rotatably connected to two side doors 15 through hinges.

[0025] When the temperature inside the top cover 2 is adjusted by the electric heating wire 10 and the refrigeration assembly, the side door 15 can be closed to keep the temperature.

[0026] like Figure 1-Figure 2 As shown, the refrigeration assembly includes a semiconductor refrigeration plate 11 fixed to the upper surface of the top cover 2, and a plurality of fins 12 are fixed to the bottom refrigeration side of the semiconductor refrigeration plate 11. The plurality of fins 12 extend through the top wall of the top cover 2 to the inside of the top cover 2.

[0027] After the semiconductor refrigeration sheet 11 is started, its refrigeration side will cool the fins 12 , and the fins 12 will then transfer the low temperature to the inside of the top cover 2 , thereby reducing the temperature inside the top cover 2 .

[0028] like Figure 2 As shown, a fan 14 is fixedly mounted on the inner wall of the top cover 2 .

[0029] When the interior of the top cover 2 is heated or cooled by the electric heating wire 10 or the refrigeration assembly, starting the fan 14 can accelerate the air flow inside the top cover 2, so that the temperature at various locations in the top cover 2 is quickly uniform.

[0030] A temperature sensor 13 is installed on the inner wall of the top cover 2. The temperature inside the top cover 2 can be detected in real time by the temperature sensor 13.

[0031] like Figure 2 and Figure 3 As shown, the pin fixing component 6 includes a socket 61 fixed to the top of the slider 5, a slot 62 is opened at the top of the socket 61, two copper sheets 63 are fixed to the bottom wall of the slot 62, the tops of the two copper sheets 63 are bent, and the sides of the two copper sheets 63 away from each other are fixedly connected to the inner wall of the slot 62 with springs 65, and the two copper sheets 63 are fixedly connected with a wire 64, and the wire 64 is electrically connected to the detector 1.

[0032] When installing the resistor, the two pins of the resistor can be respectively inserted into the slots 62 at the top of the two sockets 61, and the pins can be squeezed and fixed by using the two copper sheets 63 in the slots 62. At this time, the resistor is connected to the detector 1 through the wire 64. The spring 65 can increase the squeezing force of the copper sheet 63 on the pin, so that the pin is fixed more firmly.

[0033] like Figure 2 As shown, one end of the bidirectional screw rod 7 passes through the side wall of the slide slot 4 and is fixedly connected to a knob 8.

[0034] The bidirectional screw rod 7 is driven to rotate by rotating the knob 8, and the bidirectional screw rod 7 drives the two sliders 5 to move closer to or away from each other, thereby changing the distance between the two pin fixing components 6, and the resistors with different pin widths can be detected.

[0035] Working principle: by turning the knob 8 to adjust the distance between the two pin fixing components 6, the two pins of the resistor to be tested are respectively inserted into the slots 62 at the top of the two sockets 61, and the copper sheet 63 in the slot 62 is used to squeeze and fix the resistor pins. At this time, the resistor to be tested is connected to the detector 1 through the wire 64, and then the detector 1 is started on the display 9 for testing, and the test results are directly displayed on the display 9. When it is necessary to test the influence of different temperatures on the resistor, the electric heating wire 10 or the refrigeration component can be started by the control button 16 to change the internal temperature of the top cover 2.
