Description

Technical Field

[0001] This utility model relates to the field of resistor technology, and in particular to a combined high-performance resistor device. Background Technology

[0002] Resistors are an essential electronic component in daily life. They are mainly set in various circuits through series connection of two leads to limit the magnitude of current.

[0003] To improve resistor performance, the current method is to combine multiple resistors together to form a resistor device, and then connect the resistor device in series into the circuit for use.

[0004] However, most commonly used resistor devices are simply multiple resistors connected in series and then fixed in a frame. This type of structure often suffers from poor heat dissipation, inconvenient installation, and unstable fixing. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art and provide a combined high-performance resistor device.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0010] Furthermore, the chamber cover is also provided with a rear pin; the rear pin is located on the other side of the metal plate corresponding to the fourth hollow chamber, and passes through the chamber cover and is connected to the metal plate.

[0011] Furthermore, the resistor housing is provided with heat dissipation vents at the top, bottom, left, and right sides for heat dissipation.

[0012] Furthermore, the four hollow chambers are separated by plastic partitions; each partition is provided with heat dissipation holes.

[0013] Furthermore, the resistor housing is made of plastic; the chamber cover is made of plastic.

[0014] Compared with the prior art, the present invention has the following advantages:

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0027] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

[0028] like Figures 1-3As shown, a combined high-performance resistor device includes a resistor housing 1 made of plastic, which is non-conductive and leak-proof. The resistor housing 1 contains four cylindrical hollow chambers 2, each containing a resistor body 3. A metal spring 4 is installed at the bottom of each hollow chamber 2. A plastic chamber cover 5 is hinged to the front of the resistor housing 1, also to prevent conductivity and leakage. The chamber cover 5 is secured to the resistor housing 1 with clips. First, each resistor body 3 is placed into its respective hollow chamber 2. Due to the metal springs 4 at the bottom, the resistor body 3 protrudes from the hollow chamber 2. Closing the chamber cover 5 then pushes the resistor body 3 inward, compressing it and pressing the metal springs 4, thus securing the resistor body 3. A metal plate 6 is positioned at the front of each hollow chamber 2 of the chamber cover 5 to establish a conductive connection with the resistor body 3. The conductive connection at the other end is achieved by the metal spring 4.

[0029] To complete the series connection between each resistor body 3, the metal spring 4 in the first hollow cavity 2 and the metal spring 4 in the second hollow cavity 2 are connected by a first metal connecting plate 7; the metal plate 6 corresponding to the front of the second hollow cavity 2 and the metal plate 6 corresponding to the front of the third hollow cavity 2 are connected by a second metal connecting plate 8; and the metal spring 4 in the third hollow cavity 2 and the metal spring 4 in the fourth hollow cavity 2 are connected by a third metal connecting plate 9.

[0030] In order to connect the resistor device to an external circuit, the chamber cover 5 is provided with a front pin 10; the front pin 10 is located on the other side of the metal plate 6 corresponding to the front of the first hollow chamber 2, and passes through the chamber cover 5 and is connected to the metal plate 6; the chamber cover 5 is also provided with a rear pin 11; the rear pin 11 is located on the other side of the metal plate 6 corresponding to the front of the fourth hollow chamber 2, and passes through the chamber cover 5 and is connected to the metal plate 6.

[0031] To improve heat dissipation performance, heat dissipation vents 12 are provided on the top, bottom, left and right sides of the resistor housing 1; the four hollow chambers 2 are separated by plastic partitions 13; each partition 13 is provided with heat dissipation holes 14.

[0032] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
