Description

Technical Field

[0001] This utility model relates to the field of electronic component mounting technology, and in particular to a mounting bracket for a Hall sensor. Background Technology

[0002] Hall effect sensors, with their significant advantages such as non-contact operation, fast response, and long lifespan, are widely used in motor commutation, speed detection, and position detection. However, existing Hall effect sensors have several problems during installation. Their fixing methods are relatively simple and lack effective limiting mechanisms, making the sensors easily dropped due to accidental contact, leading to internal structural damage and severely affecting the sensor's lifespan and stability.

[0003] To address this issue, existing technologies include a Hall sensor positioning mechanism, as disclosed in Chinese Patent Publication No. CN218445933U. This mechanism can position the Hall sensor during installation, improving installation stability to some extent. However, this positioning mechanism still has significant shortcomings. Its installation and disassembly process is not convenient, reducing installation efficiency. Furthermore, the mechanism's design does not adequately consider the heat dissipation of the Hall sensor. During prolonged operation, the sensor is prone to overheating due to poor heat dissipation, affecting its performance and reliability.

[0004] Therefore, in order to optimize the ease of installation and reliability of existing Hall sensors, we propose a mounting bracket for Hall sensors. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as inconvenient installation and disassembly processes that reduce installation efficiency, and to propose a mounting bracket for a Hall sensor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The base and the mounting bracket detachably connected to the base;

[0009] The upper end of the mounting base has a mounting cavity and a pin hole communicating with the mounting cavity. The end face of the base has a clearance hole that is opposite to the pin hole.

[0010] A pressure cover is detachably connected to the mounting base above the mounting cavity, and a heat dissipation part is provided on the pressure cover.

[0011] Furthermore, the mounting base has snap-fit ​​arms on both sides of its bottom, and two snap-fit ​​holes are provided on the end face of the base, with the two snap-fit ​​arms and the two snap-fit ​​holes snapping into each other respectively.

[0012] Furthermore, the bottom of the mounting base is formed with a foolproof post, and the upper surface of the base is provided with a positioning hole that is inserted into the foolproof post.

[0013] Among them, stop wings are also formed on both sides of the mounting base to stop the upper surface of the base.

[0014] Furthermore, the pressure cap has a U-shaped structure;

[0015] The pressure cap covers the upper part of the mounting cavity, and wedge-shaped protrusions are provided on both inner sides of the pressure cap. The upper sides of the mounting base are formed with slots that fit and engage with the wedge-shaped protrusions.

[0016] Furthermore, the heat dissipation part includes a mounting hole in the middle of the pressure cover, a copper plate is embedded inside the mounting hole, a plurality of fins are formed on the upper end of the copper plate, a thermally conductive silicon pad is formed on the bottom of the copper plate, the thermally conductive silicon pad is used to contact the upper end face of the Hall sensor, and a heat dissipation cavity is also formed on the end face of the mounting cavity, facing the lower end face of the Hall sensor.

[0017] Furthermore, the base has a clearance notch at its bottom, and a plurality of mounting holes are distributed in a matrix on the end face of the base.

[0018] The present invention provides a mounting bracket for a Hall sensor, which has the following advantages: Firstly, the present invention uses a modular assembly method consisting of a base, a mounting seat, and a pressure cap to achieve the installation and fixation of the Hall sensor. Since all components are detachably connected, the installation and fixation efficiency of the Hall sensor is greatly improved. Secondly, the present invention also incorporates a heat dissipation section on the upper surface of the pressure cap to conduct heat away from the Hall sensor, thereby improving its weather resistance and reducing the impact of temperature on its detection. The overall design is simple, effectively improving the convenience and reliability of the Hall sensor during installation and operation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-4 As one embodiment of this utility model, a mounting bracket for a Hall sensor is disclosed. Specifically, the mounting bracket includes a base 1 and a mounting seat 2 detachably connected to the base 1. In this embodiment, the base 1 is used to fix the circuit board as the mounting base for the mounting seat 2.

[0026] The upper end of the mounting base 2 has a mounting cavity 21, and the interior of the mounting cavity 21 has pin holes 22 that communicate with the mounting cavity 21. Specifically, in this embodiment, there are three pin holes 22. When installing the Hall sensor 4, the pins of the Hall sensor 4 can be inserted along the three pin holes 22 until the head end of the Hall sensor 4 sinks into the interior of the mounting cavity 21, thus completing the installation of the Hall sensor 4. The end face of the base 1 has a clearance hole 11 that is opposite to the pin holes 22. The clearance hole 11 is used to ensure that the pins of the Hall sensor 4 can extend downward through the clearance hole 11 to realize the wiring and power supply of the pins.

[0027] A pressure cover 3 is detachably connected to the mounting base 2 above the mounting cavity 21, and a heat dissipation part 31 is provided on the pressure cover 3.

[0028] In some embodiments, the mounting base 2 of this invention is provided with locking arms 23 on both sides of its bottom. The locking arms 23 are L-shaped claws and are symmetrically designed. Two locking holes 12 are provided on the end face of the base 1. The two locking arms 23 and the two locking holes 12 are respectively locked together. That is, when the mounting base 2 needs to be installed, the mounting base 2 can be directly pressed onto the base 1, and the locking arms 23 on the mounting base 2 are locked together with the locking holes 12. In this way, the entire mounting base 2 can be easily installed. Conversely, the entire mounting base 2 can be disassembled by pressing the locking arms 23 on both sides to deform them and disengage them from the locking holes 12. Preferably, the mounting base 2 in this embodiment is made entirely of plastic to ensure insulation and the elasticity of the locking arms 23.

[0029] Of course, in order to ensure that the mounting base 2 and the base 1 can be installed correctly and to avoid the problem of reverse insertion of the Hall sensor 4 pins, the bottom of the mounting base 2 in this embodiment is formed with a foolproof post 24, and the upper surface of the base 1 is provided with a positioning hole 13 that is inserted into the foolproof post 24. That is, when installing the mounting base 2 and the base 1, the mounting base 2 can be engaged with the base 1 only when the foolproof post 24 and the positioning hole 13 are in the correct position, so as to avoid the problem of reverse insertion of the mounting base 2.

[0030] Among them, stop wings 25 are formed on both sides of the mounting base 2 to stop the upper surface of the base 1. The stop wings 25 are used to position the installation depth of the mounting base 2, so as to ensure that the entire mounting base 2 can be installed quickly and accurately.

[0031] Based on the above embodiments, the pressure cap 3 in this embodiment has a U-shaped structure;

[0032] The pressure cap 3 covers the upper part of the mounting cavity 21. Wedge-shaped protrusions 32 are provided on both inner sides of the pressure cap 3. The upper sides of the mounting base 2 are formed with slots 26 that are adapted to engage with the wedge-shaped protrusions 32.

[0033] Of course, the pressure cover 3 described in this embodiment is also made of plastic to ensure that its two sides have a certain deformation capacity. In this way, during the installation or disassembly of the pressure cover 3, the two sides of the pressure cover 3 can be bent to deform it, and the wedge-shaped protrusion 32 and the slot 26 can be engaged or separated to fix the pressure cover 3 above the mounting base 2, so as to press and fix the upper side of the Hall sensor 4.

[0034] It should be noted that the pin hole 22 described in this embodiment is adapted to the pin of the Hall sensor 4. The pressure cover 3 is provided to achieve the clamping and positioning of the entire Hall sensor 4. Of course, those skilled in the art can also design multiple bases 1 and mounting bases 2 of different sizes according to the model of the Hall sensor 4. This method is a conventional method for those skilled in the art and will not be elaborated here.

[0035] Furthermore, in this embodiment, the heat dissipation part 31 includes a mounting hole formed in the middle of the pressure cover 3. A copper plate 311 is embedded inside the mounting hole. A plurality of fins 312 are formed on the upper end of the copper plate 311, and a thermally conductive silicon pad 313 is formed on the bottom of the copper plate 311. The thermally conductive silicon pad 313 is used to contact the upper end face of the Hall sensor 4. A heat dissipation cavity 27 is also formed on the end face of the mounting cavity 21, facing the lower end face of the Hall sensor 4. Of course, a copper plate 311 can also be embedded in the mounting base 2 at the heat dissipation cavity 27. The copper plate 311, together with the fins 312, actively dissipates the heat inside the heat dissipation cavity 27. Those skilled in the art can choose according to actual needs, which will not be elaborated here.

[0036] In this embodiment, a copper plate 311 embedded in the upper end face of the pressure cover 3 is used for heat conduction and heat dissipation. Since the copper plate 311 can conduct heat well to the Hall sensor 4 through the thermally conductive silicon pad 313, the heat is then dissipated outward from the fins 312 on the upper surface of the copper plate 311. This achieves the purpose of actively dissipating heat when the Hall sensor 4 is working, thereby improving the weather resistance of the Hall sensor 4 and avoiding the impact of high temperature on it.

[0037] It should be noted that the base 1 in this embodiment has a clearance notch 14 at its bottom. The clearance notch 14 is used to avoid the lower claw of the snap-fit ​​arm 23, and also provides space for wiring operations between the Hall sensor 4 and the circuit board. Of course, in order to fix the base 1, several mounting holes 15 are also distributed in a matrix on the end face of the base 1 in this embodiment. The mounting holes 15 can be fixed to the circuit board by fasteners such as bolts. This method is a conventional method for those skilled in the art and will not be described in detail here.

[0038] In summary, this utility model uses a modular assembly method consisting of a base 1, a mounting base 2, and a pressure cap 3 to install and fix the Hall sensor 4. Since all components are detachably connected, the installation and fixing efficiency of the Hall sensor 4 can be greatly improved. Secondly, this utility model also designs a heat dissipation part 31 on the upper surface of the pressure cap 3 to conduct heat and dissipate heat from the Hall sensor 4, thereby improving the weather resistance of the Hall sensor 4 and reducing the impact of temperature on its detection. The overall design is simple and effectively improves the convenience and reliability of the Hall sensor 4 during installation and operation.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
