Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and particularly to a dual-resistor integrated module. Background Art

[0002] Resistors are basic components in circuits and are widely used in various electronic devices. With the improvement of circuit integration, the requirements for the performance, stability, and reliability of resistor modules are also increasing day by day. Traditional resistor modules usually encapsulate multiple resistors separately and then assemble them. This method not only has low production efficiency, but also it is difficult to ensure the connection stability between resistors. At the same time, it is easily affected by the external environment, resulting in changes in resistance values, thus affecting the stability and reliability of the circuit.

[0003] Particularly, for an integrated module containing multiple resistors, during the assembly process, due to the lack of effective positioning measures, the resistors are prone to position offset, resulting in poor connection or unstable resistance values. In addition, the fixing method of the resistors in the housing also directly affects their stability and reliability. Traditional fixing methods may have problems such as insecure fixing and easy loosening, resulting in the movement or vibration of the resistors during operation, thus affecting the normal operation of the circuit.

[0034] Resistors are basic components in circuits and are widely used in various electronic devices. With the improvement of circuit integration, the requirements for the performance, stability, and reliability of resistor modules are also increasing day by day. In traditional resistor modules, multiple resistors are usually individually encapsulated and then assembled. This method not only has low production efficiency, but also it is difficult to ensure the connection stability between resistors. At the same time, it is easily affected by the external environment, resulting in changes in resistance values, thereby affecting the stability and reliability of the circuit.

[0035] In particular, for an integrated module containing multiple resistors, during the assembly process, due to the lack of effective positioning measures, the resistors are prone to positional offset, resulting in poor connection or unstable resistance values. In addition, the fixing method of the resistors within the housing also directly affects their stability and reliability. Traditional fixing methods may have problems such as insecure fixing and easy loosening, causing the resistors to move or vibrate during operation, thus affecting the normal operation of the circuit.

[0036] Based on this, the present application provides a dual-resistor integrated module to solve the above-mentioned technical problems. The technical solutions proposed in the present application will be elaborated in detail one by one below.

[0037] Referring to Figure 1 and Figure 2 , the present application provides a dual-resistor integrated module, which includes a housing 100, a first resistor 200, a second resistor 300, a clamping structure, and a potting layer 600. An opening 110 is provided at one end of the housing 100; the first resistor 200 and the second resistor 300 are arranged side by side within the housing 100. First metal contacts 210 and second metal contacts 310 are respectively provided at the electrodes of the first ends of the first resistor 200 and the second resistor 300 close to the opening 110. The first metal contacts 210 and the second metal contacts 310 extend out from the opening 110. The electrodes of the second ends of the first resistor 200 and the second resistor 300 far from the opening 110 are connected by a conductive component 330. First card slots 220 and second card slots 320 are respectively provided at the first ends of the first resistor 200 and the second resistor 300; both ends of the clamping structure are respectively clamped within the first card slot 220 and the second card slot 320; the potting layer 600 is formed within the housing 100 for fixing the first resistor 200 and the second resistor 300 within the housing 100 and protecting them.

[0038] The first resistor 200 and the second resistor 300 are arranged side by side within the housing 100, and the electrodes at the second ends of the first resistor 200 and the second resistor 300 are connected through the conductive component 330 to form a series structure, and the integrated module is led out through the first metal contact 210 and the second metal contact 310 at the first ends. Secondly, a first card slot 220 and a second card slot 320 are respectively provided at the first ends of the first resistor 200 and the second resistor 300. By introducing a clamping structure, both ends are respectively clamped within the first card slot 220 and the second card slot 320, ensuring the accuracy of the positions between the first resistor 200 and the second resistor 300, avoiding the problem of position deviation of the first resistor 200 and the second resistor 300 during the assembly process, and thus ensuring the stability of the connection between the first resistor 200 and the second resistor 300 and the accuracy of the resistance value. In addition, the potting layer 600 fixes the first resistor 200 and the second resistor 300 within the housing 100. This fixing method is not only firm and reliable, but also can effectively prevent the resistors from moving or vibrating during operation, and can also play the roles of moisture-proof, dust-proof, and shock-proof, extending the service life of the resistors. The dual-resistor integrated module provided in this application realizes the precise positioning and stable fixing of the resistors within the housing 100, improving the overall stability and reliability of the dual-resistor integrated module.

[0039] Referring to Figure 4 , it can be understood that the first metal contact 210 includes a first U-shaped metal sheet 211 and an extension metal sheet 212. The first U-shaped metal sheet 211 is sleeved between the outer wall of the first resistor 200 and the inside of the first card slot 220. One end of the extension metal sheet 212 is connected to the first U-shaped metal sheet 211, and the other end extends out from the opening 110. The first U-shaped metal sheet 211 is sleeved between the outer wall of the first resistor 200 and the inside of the first card slot 220. The U-shaped structure of the first U-shaped metal sheet 211 can prevent the dual-resistor integrated module from moving or vibrating during operation, so as to avoid the disconnection or even detachment between the first metal contact 210 and the electrode, ensuring the stability of the dual-resistor integrated module and the normal operation of the circuit.

[0040] In addition, it should be noted that the structure of the second metal contact 310 is similar to that of the first metal contact 210, and there is no need to repeat it here to waste space. For the specific structure and function of the second metal contact 310, reference can be made to the introduction of the first metal contact 210 in the above embodiment.

[0041] It can be understood that the first metal pin 210 abuts against the inner wall of the first card slot 220 away from the second resistor 300, and the second metal pin 310 abuts against the inner wall of the second card slot 320 away from the first resistor 200. By maximizing the distance between the first metal pin 210 and the second metal pin 310, the electromagnetic coupling between them can be effectively reduced, thereby preventing the occurrence of electromagnetic interference and reducing signal crosstalk, ensuring that the resistor module can maintain stable performance during operation, and reducing the potential impact on other circuit components.

[0042] Referring to Figure 5 , it can be understood that the first resistor 200 and the second resistor 300 are respectively provided with a first connection slot 230 and a second connection slot 340 at the second end. The conductive component 330 includes a second U-shaped metal sheet 331 and two third U-shaped metal sheets 332. One of the third U-shaped metal sheets 332 is sleeved between the outer wall of the first resistor 200 and the inner wall of the first connection slot 230, and the other third U-shaped metal sheet 332 is sleeved between the outer wall of the second resistor 300 and the inner wall of the second connection slot 340; the second U-shaped metal sheet 331 is sleeved on one side where the two third U-shaped metal sheets 332 are away from each other. Similar to the first U-shaped metal disc, one of the third U-shaped metal sheets 332 is sleeved between the outer wall of the first resistor 200 and the inner wall of the first connection slot 230, and the other third U-shaped metal sheet 332 is sleeved between the outer wall of the second resistor 300 and the inner wall of the second connection slot 340, which can prevent the dual-resistor integrated module from moving or vibrating during operation. In addition, the second U-shaped metal sheet 331 is sleeved on one side where the two third U-shaped metal sheets 332 are away from each other, which can also prevent itself from falling off and shaking, and at the same time increase the contact area between the second U-shaped metal sheet 331 and the third U-shaped metal sheet 332. While avoiding the disconnection or even detachment between the conductive component 330 and the electrode, it also improves the transmission stability of the electrical signal, ensuring the stability of the dual-resistor integrated module and the normal operation of the circuit.

[0043] Referring to Figure 5 , it can be understood that one of the third U-shaped metal sheets 332 abuts against the inner wall of the first connection slot 230 close to the second resistor 300, and the other third U-shaped metal sheet 332 abuts against the inner wall of the second connection slot 340 close to the first resistor 200. Through the above design, the distance between the two third U-shaped metal sheets 332 can be minimized, improving the conductive effect.

[0044] Referring to Figure 2 and Figure 4It can be understood that the clamping structure includes an I-shaped clamping member 500, and the first clamping slot 220 and the second clamping slot 320 are T-shaped and respectively match the two ends of the clamping member 500. The clamping member 500 is in an I-shaped shape, and its two ends are matched and clamped with the first clamping slot 220 and the second clamping slot 320 in the T shape, so that it can be fixed at multiple angles on the horizontal plane, thereby ensuring the accuracy of the position between the first resistor 200 and the second resistor 300, and avoiding the position offset problem of the first resistor 200 and the second resistor 300 during the assembly process.

[0045] Reference Figure 4 and Figure 5 It can be understood that the first connection slot 230 and the first clamping slot 220 are symmetrical about the center point of the first resistor 200, and the second connection slot 340 and the second clamping slot 320 are symmetrical about the center point of the second resistor 300. Due to the symmetrical design of the connection slot and the clamping slot, the resistor does not need to distinguish between the front and back sides during assembly, and can be installed either forward or backward. This flexibility greatly simplifies the installation steps, reduces the complexity of assembly, and improves work efficiency.

[0046] Continue to refer to Figure 4 and Figure 5 It can be understood that the first card slot 220, the second card slot 320, the first connection slot 230 and the second connection slot 340 are all cross-shaped. Since the card slots and the connection slots are all designed to be cross-shaped, the resistor can be installed not only upside down but also rotated during assembly. The staff has more freedom during the assembly process and can choose the best assembly angle and direction according to actual needs, thereby greatly improving the flexibility and convenience of assembly.

[0047] Reference Figure 3 It can be understood that a plurality of protrusions 120 are provided along the circumference of the edge of the inner side of one end of the housing 100 away from the opening 110. The design of the protrusions 120 can enhance the structural strength and rigidity of the housing 100 to effectively resist external pressure and deformation and improve the overall stability of the housing 100. At the same time, the protrusions 120 can effectively increase the contact area between the potting layer 600 and the housing 100. During the potting process, the potting material will penetrate between these protrusions 120 to form a tighter combination, which not only enhances the adhesion between the potting layer 600 and the housing 100, but also improves the sealing and durability of the potting layer 600.

[0048] Reference Figure 1 and Figure 2, it can be understood that the dual-resistance integrated module provided in this application further includes a protection frame 400. The protection frame 400 is sleeved outside the housing 100, and the protection frame 400 is provided with elastic pieces 410 facing outward. As an external layer of protection, the protection frame 400 can effectively enhance the structural strength and stability of the entire module. In a vibrating or impact environment, the elastic pieces 410 can absorb part of the vibration energy, reduce the vibration amplitude inside the module, thereby improving the seismic performance of the module and ensuring its stable operation in a harsh environment. At the same time, the protection frame 400 and the elastic pieces 410 can also play a certain shielding role to prevent the influence of external static electricity and electromagnetic interference on the internal circuit of the module, ensuring the safety of the dual-resistance integrated module during use.

[0049] The embodiments of the present application have been described in detail above in conjunction with 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.
