Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more specifically to a lightweight and small filter. Background Art

[0002] Lightweight and small filters usually refer to filter products that are small in size, light in weight and can meet specific filtering requirements. With the development of electronic technology and the growing demand for portable and embedded devices, such filters have been widely used in aerospace, communication equipment, consumer electronics and other fields.

[0003] Existing lightweight and small filters often use compact structures and miniaturized components, such as film capacitors, chip inductors, etc., which greatly reduce the overall size, and use lightweight but high-strength materials with excellent conductivity, such as aluminum alloy shells to replace traditional cast iron or copper materials to further reduce weight. Although the size is small, it still needs to maintain a high filtering efficiency and good frequency response characteristics to meet the noise suppression requirements of different frequency bands.

[0004] In actual use of the prior art, since the connectors of the filter are directly exposed to the external environment when not in use, they are easily corroded by dust, moisture, rainwater, etc., which causes corrosion to the metal parts, reduces the stability of the contact resistance, and affects the working performance of the filter. Therefore, a lightweight and small filter is proposed. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the utility model provides a lightweight and small filter, which drives the insertion rod to move outward and away from the interior of the connecting base by pulling the connecting plate and the spring outward, and then inserts the transparent protective frame into the connecting base to wrap the external joint inside, and then releases the connecting plate to drive the insertion rod to move inward again into the socket through the elastic force of the spring itself, and fixes and limits the transparent protective frame. The transparent protective frame protects the external joint to prevent the external joint from being directly exposed to the environment and eroded by dust, moisture, rainwater, etc., which will cause corrosion to metal parts, reduce the stability of contact resistance, affect the working performance of the filter, and improve the safety of the filter.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) The filter of this scheme drives the plug rod to move outward from the inside of the connection base by pulling the connection plate and the spring outward, and then inserts the transparent protective frame into the connection base to wrap the external connector inside. Then, the connection plate is released and the elastic force of the spring drives the plug rod to move inward again into the socket, and the transparent protective frame is fixed and limited. The transparent protective frame protects the external connector to prevent the external connector from being directly exposed to the environment and being corroded by dust, moisture, rain, etc., which will cause corrosion to metal parts, reduce the stability of contact resistance, affect the working performance of the filter, and improve the safety of the filter.

[0018] (2) This solution uses the heat dissipation fins on the heat sink and the convex heat sink to dissipate heat, thereby preventing the filter from overheating during use, thereby affecting the filter performance, reducing the life of the components, and causing the filter to fail or be damaged.

[0032] Example 2

[0033] Reference Figure 1 , Figure 3 and Figure 4 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. Protection mechanisms 3 are provided on both sides of the filter 1, including a connection base 301 fixedly connected to both sides of the filter 1, a transparent protection frame 302 is movably connected to the inner cavity of the connection base 301, an insertion rod 303 is inserted into the inner cavity of the connection base 301, and a connection plate 305 is fixedly connected to the upper end of the insertion rod 303;

[0035] Further, the operator pulls the connecting plate 305 and the spring 306 outward to drive the insertion rod 303 to move outward and away from the interior of the connecting base 301, and then inserts the transparent protective frame 302 into the interior of the connecting base 301 to wrap the external joint 101 inside, and then loosens the connecting plate 305 to drive the insertion rod 303 to move inward again into the interior of the socket 304 through the elastic force of the spring 306 itself, and fixes and limits the transparent protective frame 302, and protects the external joint 101 through the transparent protective frame 302.

[0036] Working principle: During the use of the device, the filter 1 is electrically connected to the external circuit through the external connector 101. When in use, the filter 1 dissipates heat through the heat sink 201 and the heat sink fins 203 on the convex heat sink 202 to prevent the filter 1 from being overheated during use, thereby affecting the filter performance, reducing the life of the components, and causing the filter to fail or be damaged.
