Description

Technical Field

[0001] The utility model belongs to the technical field of sensors, and particularly relates to a special sensor for a new type of circuit board. Background Art

[0002] The circuit board miniaturizes and visualizes the circuit, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. The circuit board can be called a printed wiring board or a printed circuit board. Multiple sensors are integrated on the circuit board, including sensors for emergency power-off operations when the device fails.

[0003] There is no fixed limit structure inside the existing sensor. During installation, once the dimensional tolerance between the internal structure of the sensor and the functional component is large, the stability cannot be guaranteed, which is likely to have a certain impact on the subsequent induction detection function. Moreover, the installation of the current functional component and the sensor is also relatively cumbersome. Therefore, there are great limitations in actual use and there is room for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a special sensor for a new type of circuit board to solve the problem that there is no structure for limiting the functional component inside the existing sensor, which is likely to become loose after installation as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A special sensor for a new type of circuit board includes a housing, which is overall cylindrical, hollow inside, and has an opening reserved at the bottom; a square inner housing is installed inside the housing, and installation grooves are opened on both sides of the square inner housing. A functional component is clamped in the installation groove. The functional component is square and is adapted to the installation groove; side grooves are opened on both sides of the end face of the installation groove, and a reinforcement component is arranged in the side grooves. The reinforcement component is composed of an adjustment part and a pressing part. One part of the pressing part is placed inside the side groove, and the other part protrudes outside the side groove and abuts against the side wall of the functional component, so as to realize the pressing and limiting of the functional component, and avoid the phenomenon of unstable installation due to the tolerance problem between the square inner housing and the functional component; the adjustment part is arranged inside the pressing part and is separated from or abuts against the pressing part. Through the adjustment part, the pressing part can be pushed towards the outside of the installation groove to increase the clamping force between the pressing part and the functional component.

[0006] Preferably, the pressing part is a metal sheet, which is bent to form a vertical part and an inclined part. The vertical part is inside the side groove, and the inclined part protrudes outside the side groove and abuts against the side wall of the functional component to achieve the purpose of pressing.

[0007] Preferably, integral pressing pieces are further arranged on both sides of the vertical part of the metal sheet, and the pressing pieces are inclined and abutted against the side wall of the side groove, so as to ensure that the stable installation of the metal sheet and the side groove is not affected.

[0008] Preferably, the adjusting part is a silica gel block, which is located inside the metal sheet and fits with the vertical part of the metal sheet. A double-sided adhesive is also provided between the silica gel block and the vertical part of the metal sheet to connect the silica gel block and the metal sheet. During use, when the metal sheet presses the functional part, it will be compressed itself, and at the same time, it will press the silica gel block. Then, the silica gel block rebounds and bounces the metal sheet, achieving the purpose of further pressing the functional part by the metal sheet.

[0009] Preferably, a guiding groove is formed on the top side of the silica gel block facing the inclined part of the metal sheet, and the guiding groove fits with the inclined part of the metal sheet. Through the setting of the guiding groove, it can better fit with the metal sheet, and at the same time, it can also reduce the damage caused to the silica gel block when being squeezed, prolonging the service life.

[0010] Preferably, it further includes a bottom plate, which is located inside the housing and seals the bottom opening of the housing.

[0011] Preferably, holes for the pins to penetrate are formed on the bottom plate, and the bottom end surface of the bottom plate is on the same plane as the housing.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] Through the design of the present utility model, it can not only facilitate the rapid installation of the functional part, but also eliminate the tolerance between the internal structure size of the sensor and the functional part, ensuring that there will be no displacement phenomenon after installation, guaranteeing that the normal detection function in the later stage is not affected, and improving the deficiencies existing in the use of the existing structure.

A functional component 102 is snapped into the installation grooves 101a. The functional component 102 is square and is adapted to the installation grooves 101a;

[0026] On both sides of the end face of the installation groove 101a, side grooves 101b are formed. A reinforcement assembly is provided in the side grooves 101b. The reinforcement assembly is composed of an adjustment part and a pressing part. Among them

[0027] A part of the pressing part is placed inside the side groove 101b, and the other part protrudes outside the side groove 101b and abuts against the side wall of the functional component 102, so as to realize the pressing and limiting of the functional component 102, and avoid the phenomenon of unstable installation caused by the tolerance problem between the square inner shell 101 and the functional component 102;

[0028] The adjustment part is arranged inside the pressing part and is separated from or abuts against the pressing part. Through the adjustment part, the pressing part can be pushed towards the outside of the installation groove 101a to increase the clamping force between the pressing part and the functional component 102.

[0029] In this embodiment, preferably, the pressing part is a metal sheet 103. The metal sheet 103 is bent to form a vertical part and an inclined part. The vertical part is inside the side groove 101b, and the inclined part protrudes outside the side groove 101b and abuts against the side wall of the functional component 102 to achieve the purpose of pressing.

The connection between the silica gel block 104 and the metal sheet 103 is realized through the double-sided adhesive 105. During use, when the metal sheet 103 presses the functional part 102, it will be compressed itself, and at the same time, it presses the silica gel block 104.
