DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0031] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0032] In the field of electronic circuits, resistors are indispensable components used to control the magnitude of current and adjust the voltage distribution in the circuit. In some high-power circuits, multiple resistors need to be connected in series or in parallel, resulting in the emergence of integrated resistor modules that integrate multiple resistors into one. However, existing integrated resistor modules often contain only one resistor, or even if they contain multiple resistors, they lack effective positioning and fixing mechanisms. This makes it easy for the resistor to shift or shake inside the module, thereby affecting the accuracy of the resistance value and the stability of the circuit.

[0033] Based on this, the present application provides an integrated resistor module and an electronic device to solve the above-mentioned technical problems. The technical solutions provided by the present application are described in detail one by one below.

[0034] First, refer to Figures 1 to 3, this application provides an integrated resistor module, including: a housing 100, an insulating bracket 200, a first resistor 300, a second resistor 400, a conductive sheet 500, and a potting layer 600. One end of the housing 100 is provided with an opening 110; there are two insulating brackets 200, which are oppositely arranged in the housing 100 and perpendicular to the bottom of the housing 100. At least two mounting grooves 210 are provided on the insulating brackets 200, and the mounting grooves 210 on the two insulating brackets 200 correspond to each other one by one; the first resistor 300 is arranged in the housing 100; the second resistor 400 is arranged in the housing 100, and the electrodes at both ends are respectively clamped into the corresponding mounting grooves 210 on the other two insulating brackets 200, and the first resistor and the second resistor are connected in series or in parallel; there are two conductive sheets 500, one of the conductive sheets 500 is connected to one end of one of the first resistors 300, and the other conductive sheet 500 is connected to the other end of the second resistor 400. That is, when the first resistor 300 and the second resistor 400 are arranged side by side, one conductive sheet 500 is connected to the left end electrode of the first resistor 300, and the other conductive sheet 500 is connected to the right end electrode of the second resistor 400. The two conductive sheets 500 penetrate out of the housing 100 from different positions; the potting layer 600 is formed in the housing 100 to fix the first resistor 300, the second resistor 400, the insulating bracket 200, and the conductive sheet 500 in the housing 100.

[0035] By arranging the opposite and perpendicular insulating brackets 200 in the housing 100 and providing the mounting grooves 210 on the insulating brackets 200, the first resistor 300 and the second resistor 400 can be stably clamped into the corresponding mounting grooves 210. The first resistor 300 and the second resistor 400 are connected in series or in parallel in the housing 100 through wires. At the same time, the two conductive sheets 500 penetrate out of the housing 100 from different positions, which facilitates the connection operation with the external circuit and improves the overall working power of the module. In addition, by providing the mounting grooves 210 on the insulating brackets 200, the installation process of the first resistor 300 and the second resistor 400 is simplified, the production efficiency is improved, and at the same time, positioning and fixing can be achieved for the first resistor 300 and the second resistor 400, thereby improving the stability of the module operation. A potting layer 600 is also poured at the opening 110 of the housing 100. The potting layer 600 can firmly fix the first resistor 300, the second resistor 400, the insulating bracket 200, and the conductive sheet 500 in the housing 100, prevent them from shifting or shaking during operation, can maintain the accuracy of the resistance value, and can also improve the stability of the circuit and reduce the failure rate.

[0036] It should be noted that the housing 100 can be made of insulating material or conductive material. When the housing 100 is made of conductive material, the housing 100 can be connected to one of the conductive sheets 500, so that the entire housing 100 serves as one end electrode of the integrated resistor module. Specifically, it can be determined according to the usage requirements and no specific limitation is made here.

[0037] Referring Figure 1 and Figure 2 , it can be understood that the side wall of the housing 100 is provided with a through hole 120. One of the conductive sheets 500 extends out from the opening 110, and the other conductive sheet 500 extends out from the through hole 120. The size of the through hole 120 matches the corresponding conductive sheet 500. By providing the through hole 120 on the side wall of the housing 100 and ensuring that the size of the through hole 120 matches the corresponding conductive sheet 500, it is possible to prevent liquid from leaking out from the through hole 120 during pouring. In addition, this design enables the two conductive sheets 500 to extend out from different positions (i.e., the opening 110 and the through hole 120), which increases the flexibility of connecting the module to an external circuit. For the extending positions of the two conductive sheets 500, no limitation is made in this application, and it can be specifically adjusted according to the application scenario.

[0038] Referring Figure 3 , it can be understood that the first resistor 300 includes a resistor body 310, a first conductive post 320, and a second conductive post 330. There are two first conductive posts 320 and two second conductive posts 330, which are respectively arranged on both sides of the resistor body 310. The second conductive post 330 is connected to the end of the resistor body 310 through the corresponding first conductive post 320. The diameter of the first conductive post 320 is larger than the diameter of the second conductive post 330. The second conductive post 330 matches the installation groove 210 and is snapped into the corresponding installation groove 210. The second conductive post 330 can be snapped into the corresponding installation groove 210, which improves the convenience and stability of installation. At the same time, the installation groove 210 can also play a role in positioning the second guiding post, preventing the first resistor 300 from shaking when the integrated resistor module is in use. Similarly, the structure of the second resistor 400 is similar to that of the first resistor 300 and will not be repeated here.

[0039] Continuing to refer Figure 3 , it can be understood that the front end of the installation groove 210 is provided with a guiding port 220. The guiding port 220 is in a flared shape and is used to guide the second conductive post 330 to be snapped into the installation groove 210. The design of the guiding port 220 makes it easier for the second conductive post 330 to find the correct insertion position during installation. The flared guiding port 220 can automatically calibrate the position of the second conductive post 330 within a certain range, making the installation process simpler and reducing the possibility of installation errors.

[0040] Continuing to refer to Figure 3 , it can be understood that the conductive sheet 500 is provided with an arc-shaped contact surface at one end of the housing 100 that matches the side wall of the first conductive column 320. One of the conductive sheets 500 contacts the side surface of the first conductive column 320 at one end of the resistor body 310 through the arc-shaped contact surface. The arc-shaped contact surface at one end of the conductive sheet 500 increases the contact area between the conductive sheet 500 and the first conductive column 320. A larger contact area enables the current to be more evenly distributed, improving the conductivity and allowing the resistor to transfer current more efficiently during operation. At the same time, the arc-shaped contact makes the connection between the conductive sheet 500 and the first conductive column 320 tighter and more stable, reducing the possibility of connection loosening or poor contact caused by vibration or external stress, and improving the working stability and reliability of the resistor module.

[0041] It should be noted that the other conductive sheet 500 contacts the corresponding insulating bracket 200 through the second resistor 400. The end of this conductive sheet 500 close to the second resistor 400 is also provided with the same arc-shaped contact surface, which will not be repeated here.

[0042] Referring to Figure 3 , it can be understood that the integrated resistor module provided in this application further includes a third resistor 700. The third resistor 700 is disposed inside the housing 100, and the electrodes at both ends are respectively snapped into the corresponding mounting grooves 210 of the two insulating brackets 200. The third resistor 700 does not overlap with the first resistor 300 and the second resistor 400. The third resistor 700 is connected in series or parallel with the first resistor 300 and the second resistor 400 respectively. Specifically, the first resistor 300, the second resistor 400, and the third resistor 700 are arranged in parallel inside the housing 100. The third resistor 700 can be provided with only one or multiple, which can be specifically set according to different application scenarios. The number of mounting grooves 210 on each insulating bracket 200 is equal to the sum of the numbers of the first resistor 300, the second resistor 400, and the third resistor 700.

[0043] Referring to Figure 2It can be understood that the integrated resistor module provided by the present application further includes a positioning box 800. The positioning box 800 is arranged inside the housing 100. The insulating bracket 200, the first resistor 300 and the second resistor 400 are arranged inside the positioning box 800. The length inside the positioning box 800 matches the length of the insulating bracket 200. By presetting the positions of the resistors and the insulating bracket 200 inside the positioning box 800, the assembly process of the resistor module can be greatly simplified. The operator only needs to put the positioning box 800 into the housing 100 as a whole, without separately adjusting the positions of each component, thereby improving the assembly efficiency. The existence of the positioning box 800 can also provide certain protection for the internal resistors and the insulating bracket 200, preventing them from being affected by external impacts or vibrations, prolonging the service life of the resistor module, and improving its working stability.

[0044] It can be understood that the potting layer 600 is made of an insulating and flame-retardant material, such as silicone rubber and other materials, and the present application does not make any limitations thereto.

[0045] In a second aspect, the present application further provides an electronic device, including the integrated resistor module according to any one of the first aspect. The functions and principles of the electronic device in this embodiment are all based on the above integrated resistor module. Therefore, the electronic device in this embodiment has the same beneficial effects as the above integrated resistor module. For the sake of brevity, the description will not be repeated here.

[0046] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present application.
