Description

Technical Field

[0001] The utility model relates to the technical field of power supply filters, and more specifically, to an anti-vibration power supply filter. Background Art

[0002] A power filter is a device used to reduce interference signals in a power supply. It mainly filters out high-frequency interference signals in the power supply to ensure the normal operation of electronic equipment. In electronic equipment, the power filter can act as a "bodyguard" for the power supply system, protecting the electronic equipment from interference.

[0003] In the prior art, the power filter is usually installed directly inside the device, and then the cables are connected to the terminal. However, due to the small installation space, when the device is vibrated, the existing filter cannot effectively resist the vibration, which can easily cause the power filter and its connection port to become loose, and even cause damage to the internal connection components, thereby affecting the stability and use effect of the power filter.

[0004] Therefore, it is necessary to provide an anti-vibration power supply filter to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-vibration power supply filter to solve the problems raised in the above background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0011] The technical solution of the utility model is further configured as follows: the rotation fulcrum is eccentrically arranged toward an end of the connecting rod away from the filter body.

[0012] The technical solution of the utility model is further configured as follows: the connecting rod is a telescopic rod and the telescopic end thereof is rotatably connected to the filter body.

[0013] The technical solution of the utility model is further configured as follows: a plurality of wire harness assemblies are provided on the filter body, and the wire harness assemblies include a slide rail and a plurality of pairs of sliders, the slide rail is fixedly connected to the top surface of the filter body, and a plurality of pairs of sliders are slidably connected to the slide rail and the sliding directions of a pair of sliders are arranged opposite to each other.

[0022] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model. Example

[0023] like Figures 1 to 3 As shown, the utility model provides an anti-vibration power supply filter, including a filter body 1 and a plurality of wiring terminals 2 arranged at both ends thereof, protective plates 3 are arranged on both sides of the filter body 1, a fixing frame 4 is fixedly connected to the protective plates 3, an elastic member 5 (a spring is used here) is arranged in the fixing frame 4, two connecting rods 6 are arranged on both sides of the filter body 1, the connecting rod 6 is a telescopic rod and its telescopic end is rotatably connected to the filter body 1, one end of the two connecting rods 6 away from the filter body 1 is respectively abutted against the two ends of the elastic member 5, both ends of the fixing frame 4 in the length direction are rotatably connected to support rods 7, one end of the support rod 7 away from the fixing frame 4 is rotatably connected to the connecting rod 6 and forms a rotation fulcrum on the connecting rod 6.

[0024] like Figures 1 to 3 As shown, the end of the connecting rod 6 away from the filter body 1 is rotatably connected to a push rod 8, two push plates are slidably connected in the fixed frame 4, the two push plates are fixedly connected to the two ends of the elastic member 5, the end of the push rod 8 away from the connecting rod 6 is fixedly connected to the push plate, the top surface of the fixed frame 4 is provided with a slide groove 9 connected to the interior thereof, and a protrusion 10 extending from the slide groove 9 is fixedly connected to the push plate.

[0025] When the filter body 1 is vibrated away from the filter body 1, it can drive one end of the connecting rod 6 to move, so that the connecting rod 6 can rotate to a certain extent around the fulcrum formed by the support rod 7, and the push rod 8 on the connecting rod 6 can push the push plate located in the fixed frame 4. The push plate will move along the slide groove 9 through the protrusion 10, squeezing the elastic member 5 in the fixed frame 4 to achieve the effect of buffering vibration. In this process, because the connecting rod 6 is a telescopic rod, it can extend and shorten to a certain extent with the vibration of the filter body 1, avoiding affecting the rotation of the connecting rod 6 around the fulcrum.

[0026] like Figures 1 to 3 As shown, two extension blocks 11 are fixedly connected to one side of the fixed frame 4 away from the protective plate 3. The two extension blocks 11 are respectively located at the two ends of the length direction of the fixed frame 4. The support rod 7 is rotatably connected to the extension blocks 11, and the rotation fulcrum is eccentrically arranged toward the end of the connecting rod 6 away from the filter body 1.

[0027] The support rod 7 is connected to the fixed frame 4 through the extension block 11, so that when the filter body 1 is not subjected to vibration, the support rod 7 and the protective plate 3 can be kept as parallel as possible, and since the fulcrum formed by the support rod 7 on the connecting rod 6 is eccentrically set, the power arm on the connecting rod 6 is larger than the resistance arm, so that a slight vibration can also drive the connecting rod 6 to rotate, thereby achieving a buffering effect and reducing the influence of vibration on the filter body 1 as much as possible.

[0028] like Figures 1 to 3 As shown, a plurality of wire harness assemblies are provided on the filter body 1, and the wire harness assemblies include a slide rail 12 and a plurality of pairs of sliders 13. The slide rail 12 is fixedly connected to the top surface of the filter body 1, and the plurality of pairs of sliders 13 are slidably connected to the slide rail 12, and the sliding directions of a pair of sliders 13 are arranged facing each other. A pair of sliders 13 are provided with a fixed block 14 fixedly connected to the slide rail 12 on one side away from each other, and a limiting rod 15 is slidably connected to the fixed block 14, which penetrates through the fixed block 14 and is fixedly connected to the slider 13, and a spring is sleeved on the area where the limiting rod 15 is located between the slider 13 and the fixed block 14.

[0029] Through the wiring harness assembly, the cable connected to the terminal 2 on the filter body 1 can be bound and fixed by the slider 13 on the slide rail 12, and the slider 13 is subjected to the force of the spring on the limiting rod 15, so that the pair of sliders 13 are close to each other and fit together, and the cable is bound and clamped, thereby preventing the cable connected to the terminal 2 from being separated from the filter body 1 when the filter body 1 is vibrated, further ensuring the stability of the filter body 1. When the connection between the cable and the terminal 2 needs to be disconnected, it is only necessary to pull the limiting rod 15 on the fixing block 14 and remove the cable from the pair of sliders 13.

[0030] like Figures 1 to 3As shown, when the filter body 1 is vibrated, the filter body 1 will deviate in one direction, thereby driving the connecting rods 6 on both sides to rotate around the fulcrum. During this process, the connecting rods 6 on the same side of the filter body 1 remain parallel, while the two support rods 7 deviate one toward the filter body 1 and the other toward the fixed frame 4, thereby driving the push plates at both ends of the elastic member 5 to slide along the slide groove 9, and the sliding directions of the two push plates are the same, but due to the presence of the protrusion 10 and the slide groove 9, only one push plate can be pushed by the push rod 8 to squeeze the elastic member 5, so that the elastic member 5 can achieve the effect of buffering vibration in a fixed state, thereby avoiding the power filter from loosening, thereby affecting the stability of the power filter.

[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
