Description

Technical Field

[0001] This application relates to the field of resistors, and more particularly to a flexible-connected aluminum-cased resistor. Background Technology

[0002] Resistors are commonly used passive components in electronic circuit design and are widely used in various electronic devices. As electronic devices become smaller and more integrated, the layout density of circuit boards is increasing, placing higher demands on the installation and connection of components.

[0003] Currently, resistor leads are typically constructed by installing steel core wires at both ends of the resistor, extending the steel core wires beyond the resistor's exterior, and then connecting the electrical wires to these steel core wires. Because steel core wires are relatively rigid and difficult to bend, the steel core wires extending beyond the resistor's ends increase the space occupied by the resistor, resulting in a larger installation space required and making it difficult to meet the need for a smaller footprint. Utility Model Content

[0004] To reduce the installation space occupied by the resistor, this application provides an aluminum-cased resistor with a flexible connection at the wiring point.

[0005] The flexible connection aluminum shell resistor provided in this application adopts the following technical solution:

[0006] A flexible aluminum-cased resistor with a flexible connection includes a resistor body, a galvanized iron cap, and a flexible wire. The galvanized iron cap is provided at both ends inside the resistor body, and the flexible wire passes through the resistor body and is connected to the galvanized iron cap.

[0007] By adopting the above technical solution, the galvanized iron cap is installed inside the resistor body, and then the flexible wire is threaded through the resistor body and connected to the galvanized iron cap, which directly realizes the connection between the flexible wire and the resistor body. When installing the resistor body later, the flexible wire can be bent as needed, effectively reducing the installation space occupied by the resistor.

[0008] Optionally, the resistor body includes an aluminum alloy shell, a resistor core, and a filler, wherein the resistor core is disposed inside the aluminum alloy shell, and the filler is filled between the resistor core and the aluminum alloy shell.

[0009] By adopting the above technical solution, the aluminum alloy shell protects the resistor core, and the filler fills the space between the resistor core and the aluminum alloy shell, increasing the stability of the resistor core, galvanized iron cap and flexible wire inside the aluminum alloy shell, thereby improving the stability and reliability of the resistor.

[0010] Optionally, the galvanized iron cap is provided to cover the end of the resistor core.

[0011] By adopting the above technical solution, the galvanized iron cap is used to cover the resistor core, thereby improving the stability of the resistor core.

[0012] Optionally, the aluminum alloy casing has multiple grooves.

[0013] By adopting the above technical solution, multiple grooves increase the structural strength of the aluminum alloy shell and increase the surface area of ​​the aluminum alloy shell, which is beneficial for heat dissipation of the aluminum alloy shell.

[0014] Optionally, the aluminum alloy housing is provided with lugs for screws to pass through.

[0015] By adopting the above technical solution, when positioning and installing the aluminum alloy shell, the screws can be easily positioned and installed by passing them through the lugs and screwing them into the installation position.

[0016] Optionally, the aluminum alloy shell is provided with a positioning component for positioning the flexible wire. The positioning component includes a positioning plate and a control component. One positioning plate is slidably disposed on each side of the aluminum alloy shell, and the control component is disposed on the aluminum alloy shell and is used to drive the two positioning plates to move closer to each other.

[0017] By adopting the above technical solution, after the flexible wire is connected to the galvanized iron cap, the two positioning plates are driven to move closer to each other by the control components. The two positioning plates can clamp and position the flexible wire, reducing the possibility of the flexible wire coming off the galvanized iron cap and improving the stability of the flexible wire in the aluminum alloy shell.

[0018] Optionally, the control component includes a bidirectional screw, which is rotatably mounted on an aluminum alloy housing and threadedly connected to both positioning plates. The bidirectional screw is used to drive the two positioning plates closer to or further apart from each other.

[0019] By adopting the above technical solution, the two positioning plates can be easily driven to move closer or further apart by turning the bidirectional screw.

[0020] Optionally, the positioning plate is arranged in an arc shape to fit against the outer wall of the flexible wire.

[0021] By adopting the above technical solution, the arc-shaped positioning plate increases the contact area with the flexible wire, thereby enhancing the stability of clamping the flexible wire.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Directly connects the flexible wire to the resistor body. When installing the resistor body later, the flexible wire can be bent as needed, effectively reducing the installation space occupied by the resistor.

[0024] 2. Two positioning plates can clamp and position the wire, reducing the possibility of the wire coming off the galvanized iron cap and improving the stability of the wire inside the aluminum alloy shell. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] Example 1

[0031] This application discloses a flexible aluminum-cased resistor with a flexible connection at the wiring point.

[0032] Reference Figure 1 , Figure 2 The flexible aluminum-cased resistor at the connection point includes a resistor body 1, a galvanized iron cap 2, and a flexible wire 3. The resistor body 1 includes an aluminum alloy shell 11, a resistor core 12, and a filler 13. The aluminum alloy shell 11 is hollow inside and open at both ends. Multiple grooves 4 are formed on the aluminum alloy shell 11. The multiple grooves 4 form multiple raised ridge-like supports on the aluminum alloy shell 11, which improves the structural strength of the aluminum alloy shell 11 and increases the surface area of ​​the aluminum alloy shell 11, which is beneficial for dissipating the heat of the resistor core 12 through the aluminum alloy shell 11 during subsequent resistor operation.

[0033] Reference Figure 1 , Figure 2 The aluminum alloy housing 11 has multiple lugs 5 mounted on its side wall, and each lug 5 has a through hole for screws to pass through. When positioning and installing the aluminum alloy housing 11 onto the equipment, screws are passed through the lugs 5 and screwed into the mounting position on the equipment, thus conveniently positioning and installing the aluminum alloy housing 11 onto the equipment.

[0034] Reference Figure 1 , Figure 2The resistor core 12 is installed inside the aluminum alloy casing 11, and the filler 13 is filled between the resistor core 12 and the aluminum alloy casing 11. In this embodiment, the filler 13 is composed of insulating materials such as silicides and ceramic particles. The aluminum alloy casing 11 encloses the resistor core 12, thereby protecting it. The filler 13 fills the space between the resistor core 12 and the aluminum alloy casing 11, increasing the stability of the resistor core 12, the galvanized iron cap 2, and the flexible wire 3 within the aluminum alloy casing 11, thereby improving the stability and reliability of the resistor.

[0035] Reference Figure 1 , Figure 2 One galvanized iron cap 2 is installed at each end of the resistor core 12. The flexible wire passes through both ends of the aluminum alloy shell 11 and is welded to the galvanized iron cap 2. The galvanized iron cap 2 covers the resistor core 12, improving its stability and facilitating the subsequent connection of the flexible wire 3.

[0036] The implementation principle of Embodiment 1 of this application is as follows: First, the resistor core 12 is installed inside the aluminum alloy shell 11. Then, the galvanized iron cap 2 is wrapped and installed on both ends of the resistor core 12. Next, the flexible wire 3 is inserted into the aluminum alloy shell 11 and welded to the galvanized iron cap 2, so that the flexible wire 3 and the resistor core 12 can be connected. Then, the filler 13 is filled into the aluminum alloy shell 11. When installing the resistor later, the flexible wire 3 can be bent as needed, effectively reducing the installation space occupied by the resistor.

[0037] Example 2

[0038] Reference Figure 3 The difference between this embodiment and Embodiment 1 is that a positioning component 6 is installed on the aluminum alloy shell 11. The positioning component 6 is used to position the flexible wire 3. The positioning component 6 includes a positioning plate 61 and a control component. One positioning plate 61 is slidably installed on the inner wall of each side of the aluminum alloy shell 11. The two positioning plates 61 are located on both sides of the flexible wire 3. The side of the positioning plate 61 facing the flexible wire 3 is arc-shaped and fits against the outer wall of the flexible wire 3, so that when the positioning plate 61 abuts against the flexible wire 3, it can have a larger contact area with the flexible wire 3, thereby enhancing the stability of the positioning plate 61 in clamping the flexible wire 3.

[0039] Reference Figure 3 The control component 62 is mounted on the aluminum alloy housing 11. The control component 62 is used to drive the two positioning plates 61 to move closer to each other. The control component 62 includes a bidirectional screw 621, which is rotatably mounted on the aluminum alloy housing 11. The bidirectional screw 621 is threadedly connected to both positioning plates 61. The two threads of the bidirectional screw 621 connected to the two positioning plates 61 are in opposite directions, and the bidirectional screw 621 is embedded in the outer wall of the aluminum alloy housing 11 to avoid the bidirectional screw 621 extending into the aluminum alloy housing 11 and occupying space.

[0040] The implementation principle of Embodiment 2 of this application is as follows: After the flexible wire 3 is welded to the galvanized iron cap 2, the double-ended screw 621 is turned. The double-ended screw 621 drives the two positioning plates 61 to move closer to each other. The two positioning plates 61 can clamp and support a section of flexible wire located inside the aluminum alloy shell 11, reducing the possibility of the flexible wire 3 detaching from the galvanized iron cap 2 and improving the stability of the flexible wire 3 inside the aluminum alloy shell 11.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
