Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and in particular to a mounting bracket for a power filter capacitor in an automotive amplifier. Background Technology

[0002] The power supply filter capacitor is a key component in the power supply circuit of an automotive amplifier. Its main function is to stabilize the power supply voltage and filter out noise in the current. The power supply of an automotive amplifier comes from the car battery, and its output DC power is not absolutely pure. It is mixed with high-frequency interference generated by the engine, circuit switches, etc., as well as low-frequency fluctuations (ripple) after rectification. If these noises directly enter the amplifier circuit, they will cause sound quality distortion (such as static, current noise), and may even affect the stable operation of the amplifier chip.

[0003] In existing technologies, power filter capacitor brackets typically fix capacitors of a single size. When equipment maintenance or upgrades require the replacement of filter capacitors of different sizes, the original brackets become unusable due to size mismatch and must be replaced along with the capacitors. This not only increases replacement costs but also leads to the old brackets being idle and wasted, thus increasing resource waste. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a mounting bracket for the power filter capacitor of an automotive amplifier.

[0005] This utility model is achieved by the following technical solution: a power filter capacitor fixing bracket for an automotive amplifier, comprising a housing, a rubber isolation plate fixedly connected to the inner wall of the housing, a capacitor disposed on the inner wall of the housing, a clamping assembly disposed inside the housing, a pressing assembly disposed at the top of the housing, and a fixing assembly disposed at the bottom of the housing;

[0006] The clamping assembly includes a sliding groove, a sliding plate slidably connected to the outer wall of the sliding groove, a rubber plate fixedly connected to the outer wall of the sliding plate, a threaded rod threadedly connected inside the sliding plate, a worm gear fixedly connected to the outer wall of the end of the threaded rod away from the sliding plate, a worm engaging with the worm gear, and a knob fixedly connected to the outer wall of the end of the worm gear away from the worm gear.

[0007] As a further improvement to the above solution, the slide groove is formed at the bottom of the inner wall of the housing, the threaded rod is rotatably connected inside the housing, and the worm gear is rotatably connected inside the housing.

[0008] With the above technical solution, after the capacitor is placed inside the housing, the rubber isolation plate can initially isolate the two capacitors, preventing them from being squeezed or collided. A person rotates a knob to drive the worm gear, which meshes with the worm wheel. The worm wheel rotates, driving the threaded rod to rotate inside the housing. Simultaneously, the threaded rod is threadedly connected to the sliding plate, causing the sliding plate to slide against the outer wall of the groove, thus clamping and fixing the capacitor. Furthermore, by adjusting the sliding plate, capacitors of different sizes can be fixed without replacing the housing due to changes in capacitor specifications. This reduces production and maintenance costs, minimizes resource waste, and improves the equipment's versatility and economy.

[0009] As a further improvement to the above solution, the pressing assembly includes a screw threadedly connected to the top of the housing, and a cover plate threadedly connected to the screw.

[0010] As a further improvement to the above solution, a sliding rod is slidably connected to the inner wall of the cover plate, and a rubber pressure plate is fixedly connected to the bottom of the sliding rod.

[0011] As a further improvement to the above solution, a limiting piece is fixedly connected to the end of the sliding rod away from the rubber pressure plate, and a spring is sleeved on the outer wall of the sliding rod.

[0012] Through the above technical solution, the rubber pressure plate presses the top of the capacitor under the action of the spring, thereby limiting the capacitor for a second time. The limiting plate prevents the sliding rod from falling off the cover plate. The secondary fixation enhances the fixing effect of the capacitor and effectively prevents the capacitor from longitudinally displacing. Together with the clamping assembly, it forms an all-round fixed protection.

[0013] As a further improvement to the above solution, the fixing component includes a rubber plate, which is fixedly connected to the bottom of the outer casing.

[0014] As a further improvement to the above solution, a fixing plate is fixedly connected to one end of the rubber sheet away from the outer shell, and a fixing screw is threadedly connected inside the fixing plate.

[0015] Through the above technical solution, the rubber plate at the bottom of the housing can effectively absorb and weaken the vibration generated during vehicle operation, prevent the vibration from being directly transmitted to the capacitor, reduce the loss of the capacitor caused by continuous vibration, extend its service life, and reduce the replacement frequency. With the fixing plate and fixing screw, the entire mounting bracket can be firmly installed in the designated position of the car amplifier.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention, by placing the capacitor inside the housing, allows the rubber isolation plate to initially separate the two capacitors, preventing them from squeezing or colliding. A person rotates a knob to drive the worm gear, which meshes with a worm wheel. The worm wheel's rotation drives the threaded rod to rotate inside the housing. Simultaneously, the threaded rod is threadedly connected to a sliding plate, causing the sliding plate to slide against the outer wall of the groove, thus clamping and fixing the capacitor. Furthermore, by adjusting the sliding plate, capacitors of different sizes can be fixed without replacing the housing due to changes in capacitor specifications. This reduces production and maintenance costs, minimizes resource waste, and improves the equipment's versatility and economy.

[0018] This utility model effectively absorbs and weakens vibrations generated during vehicle operation through the rubber plate at the bottom of the outer shell, preventing vibrations from being directly transmitted to the capacitor, reducing losses caused by continuous vibrations, extending its service life, and reducing replacement frequency. The fixing plate and fixing screws can firmly install the entire mounting bracket in the designated position of the car amplifier. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5 This embodiment provides a power filter capacitor mounting bracket for an automotive amplifier, comprising a housing 1, a rubber isolation plate 2 fixedly connected to the inner wall of the housing 1, a capacitor 3 disposed on the inner wall of the housing 1, a clamping assembly 4 disposed inside the housing 1, a pressing assembly 5 disposed on the top of the housing 1, and a fixing assembly 6 disposed on the bottom of the housing 1.

[0029] The clamping assembly 4 includes a slide groove 401, a slide plate 402 slidably connected to the outer wall of the slide groove 401, a rubber plate 403 fixedly connected to the outer wall of the slide plate 402, a threaded rod 404 threadedly connected inside the slide plate 402, a worm gear 405 fixedly connected to the outer wall of the end of the threaded rod 404 away from the slide plate 402, a worm 406 meshing with the worm gear 405, and a knob 407 fixedly connected to the outer wall of the end of the worm 406 away from the worm gear 405.

[0030] The slide groove 401 is formed at the bottom of the inner wall of the housing 1, the threaded rod 404 is rotatably connected to the inside of the housing 1, and the worm gear 406 is rotatably connected to the inside of the housing 1.

[0031] The pressing assembly 5 includes a screw 501, which is threaded to the top of the housing 1 and has a cover plate 502 threaded to it.

[0032] A sliding rod 503 is slidably connected to the inner wall of the cover plate 502, and a rubber pressure plate 504 is fixedly connected to the bottom of the sliding rod 503.

[0033] A limiting piece 505 is fixedly connected to the end of the sliding rod 503 away from the rubber pressure plate 504, and a spring 506 is sleeved on the outer wall of the sliding rod 503.

[0034] The fixing component 6 includes a rubber plate 601, which is fixedly connected to the bottom of the housing 1.

[0035] A fixing plate 602 is fixedly connected to the end of the rubber sheet 601 away from the outer shell 1, and a fixing screw 603 is threadedly connected inside the fixing plate 602.

[0036] The implementation principle of the power filter capacitor fixing bracket for an automotive amplifier in this embodiment is as follows: After the capacitor 3 is placed inside the housing 1, the rubber isolation plate 2 can initially isolate the two capacitors 3 to prevent squeezing and collision between them. A person rotates the knob 407 to drive the worm gear 406 to rotate. The worm gear 406 meshes with the worm wheel 405, and the worm wheel 405 rotates, driving the threaded rod 404 to rotate. The threaded rod 404 rotates inside the housing 1, and simultaneously, the threaded rod 404 is threadedly connected to the sliding plate 402, causing the sliding plate 402 to drive the rubber plate 403 to slide on the outer wall of the groove 401, thereby clamping and fixing the capacitor 3. Furthermore, by adjusting the sliding plate 402, capacitors 3 of different sizes can be fixed without replacing the housing 1 due to changes in capacitor 3 specifications. This reduces production and maintenance costs, minimizes resource waste, and improves the versatility and economy of the equipment. The screw 501 will... Cover plate 502 is installed on the top of housing 1. Cover plate 502 prevents foreign objects from entering the interior of housing 1, thereby protecting capacitor 3. Sliding rod 503 slides inside cover plate 502. Rubber pressure plate 504 presses the top of capacitor 3 under the action of spring 506, thereby limiting capacitor 3 for a second time. Limiting piece 505 prevents sliding rod 503 from detaching from cover plate 502. The secondary fixation enhances the fixing effect of capacitor 3 and effectively prevents longitudinal displacement of capacitor 3. Together with clamping assembly 4, it forms all-round fixed protection. Rubber plate 601 at the bottom of housing 1 can effectively absorb and weaken the vibration generated during vehicle operation, avoid vibration directly transmitted to capacitor 3, reduce the wear caused by continuous vibration to capacitor 3, extend its service life, and reduce replacement frequency. Through fixing plate 602 and fixing screw 603, the entire fixing bracket can be firmly installed in the designated position of car amplifier.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
