Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a novel filter. Background Technology

[0002] Electronic information engineering involves multiple fields such as electronic technology, information processing, communication engineering, and computer science. A filter is a device used for signal processing. Its main function is to remove unwanted frequency components from the input signal and retain or enhance the desired frequency components. In electronic information engineering, filters are an indispensable and important component in signal processing and communication systems. They are used to remove unwanted frequency components and retain or enhance the desired signal. When using filters, it is necessary to install them with external circuits. However, it is inconvenient for staff to install and disassemble external circuits. Therefore, there is a lack of filters in the current technology that solves this problem.

[0003] To address this issue, a search revealed a novel filter disclosed in patent application number 202222645438.8. This filter is secured by a limiting washer and a fastening nut, facilitating quick installation and easy disassembly of the wiring harness. The protective plate protects the wiring harness connections, preventing the harness from detaching during impacts, thus providing good protection for the wiring harness.

[0004] In practical use, the external wiring harness of this new filter is clamped between the limiting washer and the fastening nut. The external wiring harness is clamped and fixed by rotating the fastening nut. This connection has two problems. First, when the rotating fastening nut is pressed against the external wiring harness, it is easy to cause friction damage to the external wiring harness. Second, it does not effectively limit the stability of the external wiring harness. After the fastening nut loosens, the external wiring harness is easy to detach from the filter's wiring terminal, thus affecting the filtering function. Therefore, we propose a new type of filter. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a novel filter, including a filter body, with a connecting post connected to one end of the filter body, and further comprising:

[0006] A fixing plate is attached to the outside of the connecting post;

[0007] A pressing component is disposed outside the connecting post, and the pressing component can be close to or far from the fixed abutment;

[0008] An inlet groove for inserting external wiring harnesses is provided on the axial direction of the connecting post, and an outlet groove for the external wiring harnesses to exit is provided at the inner end of the inlet groove. The outlet groove penetrates the outer wall of the connecting post, and the end opening of the outlet groove is located in front of the fixing abutment.

[0009] In some embodiments, the pressing assembly includes a movable pressure plate sleeved on the outside of the connecting column, the movable pressure plate having at least two threaded rods passing through it, one end of each threaded rod being fixed to a fixed pressure plate, and a nut being screwed onto the outside of each threaded rod.

[0010] In some embodiments, the inlet groove is provided with a tapered guide post, the outer diameter of the tapered guide post is smaller than its inner diameter, the inner end of the tapered guide post extends to the bottom of the outlet groove, and a plug is fixed to the inner end of the tapered guide post.

[0011] In some embodiments, the transition between the inlet slot and the outlet slot is integrally formed as an outlet ramp.

[0012] In some embodiments, the diameter of the movable pressure plate is not less than the diameter of the fixed pressure plate.

[0013] In some embodiments, the movable pressure plate is provided with a protective member on its exterior, the protective member being used to protect the external wiring harness that passes through the guide slot from the periphery.

[0014] In some embodiments, the protective member includes an annular baffle fixed to the outer circumference of the movable pressure plate, the inner wall of the annular baffle being fixed with a moisture-proof cotton pad, and the inner diameter of the annular baffle being larger than the diameter of the fixed pressure plate.

[0015] This utility model has at least the following beneficial effects:

[0016] 1. By setting inlet and outlet slots on the connecting post, the stability of the external wiring harness in contact with the connecting post can be increased when connecting the external wiring harness, which can reduce the occurrence of scattering and prevent the wiring harness from falling off during collision. In addition, the set tapered guide post can guide the external wiring harness when it is inserted, which is conducive to the external wiring harness passing through the outlet slot and can reduce the difficulty of insertion.

[0017] 2. When locking and positioning the external wiring harness that passes through the guide slot, the movable pressure does not rotate, which can reduce the occurrence of friction damage to the wiring harness caused by contact with the external wiring harness.

[0018] 3. A protective component is installed. When the movable pressure plate is pressed against the fixed abutment to hold down the external wiring harness, the annular baffle moves to the outside of the fixed abutment, which can protect the external wiring harness between the movable pressure plate and the fixed abutment. In addition, the moisture-proof cotton pad is filled at the transition between the annular baffle and the fixed abutment to effectively absorb moisture and prevent dampness, reducing the occurrence of moisture.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figures 1-5As shown, this utility model provides a solution: a novel filter, including a filter body 1, with a connecting post 2 connected to the end of the filter body 1. The filter body 1 has heat dissipation holes to facilitate the dissipation of heat generated by internal components. A dustproof mesh can be installed at the heat dissipation holes to prevent dust from entering. A mounting plate is connected to the bottom of the outer wall of the filter body 1, and mounting screw holes are provided on the mounting plate for screws to pass through for mounting the filter body 1. It also includes a fixing abutment 3, an inlet groove 4, and a pressing assembly 5. The fixing abutment 3 is fixed to the outside of the connecting post 2, and the inlet groove 4 is for the insertion of external wiring harnesses. The inlet groove 4 has... Along the axial direction of the connecting post 2, the inlet groove 4 is open at the end of the connecting post 2, and the inner end of the inlet groove 4 is provided with an outlet groove 6 for the external wiring harness to pass through. The outlet groove 6 penetrates the outer wall of the connecting post 2 so that the external wiring harness can pass through the outlet groove 6. The end opening of the outlet groove 6 is located in front of the fixed abutment 3. The transition between the inlet groove 4 and the outlet groove 6 is integrally formed into an outlet slope 10 to facilitate the external wiring harness to pass through the transition. The pressing component 5 is located outside the connecting post 2, and the pressing component 5 can be close to or away from the fixed abutment 3. The end of the external wiring harness that passes through the outlet groove 6 is fixed by the pressing component 5 and the fixed abutment 3.

[0030] In the specific embodiments of this utility model, see [reference needed]. Figure 3 As shown, the pressing component 5 includes a movable pressing plate 51 sleeved on the outside of the connecting column 2. The diameter of the movable pressing plate 51 is not less than the diameter of the fixed pressing plate 3, and at least two threaded rods 52 are provided through the movable pressing plate 51. One end of the threaded rod 52 is fixed to the fixed pressing plate 3, and a nut 53 is screwed onto the outside of the threaded rod 52.

[0031] See Figure 4 As shown, the inside of the inlet groove 4 is provided with a tapered guide post 8. The outer diameter of the tapered guide post 8 is smaller than its inner diameter. The inner end of the tapered guide post 8 extends to the bottom directly opposite the outlet groove 6, and a plug post 9 is fixed to the inner end of the tapered guide post 8.

[0032] As described above, when connecting the external wiring harness, the end of the external wiring harness can be inserted into the inlet groove 4 and then out through the outlet groove 6, so that part of the end of the external wiring harness is between the movable pressure plate 51 and the fixed abutment 3. Then the sleeved movable pressure plate 51 can be moved to press the external wiring harness against the movable pressure plate 51. After that, the nut 53 outside the threaded rod 52 can be rotated to lock and position it.

[0033] The use of the inlet slot 4 and outlet slot 6 increases the stability of the external wiring harness contacting the connecting post 2 when connecting the external wiring harness, reduces the occurrence of scattering, and prevents the wiring harness from falling off during collision. In addition, the tapered guide post 8 can guide the external wiring harness when it is inserted, making it easier for the external wiring harness to pass through the outlet slot 6 and reducing the difficulty of insertion.

[0034] In addition, when locking and positioning the external wiring harness that passes through the guide slot 6, the movable pressure plate 51 does not rotate, which can prevent contact with the external wiring harness and damage to the wiring harness.

[0035] Example 2

[0036] Please see Figure 2 As shown, this embodiment is an extension based on embodiment one. Specifically, a protective member 7 is provided on the outside of the movable pressure plate 51. The protective member 7 is used to protect the external wiring harness that passes through the guide slot 6 from the outside.

[0037] The protective component 7 includes an annular baffle 71 fixed on the outer circumference of the movable pressure plate 51. A moisture-proof cotton pad 72 is fixed on the inner wall of the annular baffle 71, and the inner diameter of the annular baffle 71 is larger than the diameter of the fixed pressure plate 3.

[0038] As described above, when the movable pressure plate 51 abuts against the fixed abutment 3 and presses against the external wiring harness, the annular baffle 71 moves to the outside of the fixed abutment 3, which can effectively protect the external wiring harness between the movable pressure plate 51 and the fixed abutment 3. Furthermore, by filling the transition area between the annular baffle 71 and the fixed abutment 3 with the moisture-proof cotton pad 72, moisture absorption and moisture prevention can be effectively achieved, reducing the occurrence of dampness.
