Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic capacitors, in particular to an anti-falling electrolytic capacitor. Background Art

[0002] Electrolytic capacitors are a type of capacitor that are characterized by their very large capacitance per unit volume and the ability to store more energy than other types of capacitors. They usually consist of a metal foil (such as aluminum or tantalum) as the positive electrode, an insulating oxide layer (aluminum oxide or tantalum pentoxide) on the metal foil as the dielectric, and a cathode composed of a thin paper, film, or electrolyte polymer soaked in an electrolyte solution, which can be liquid or solid.

[0003] With reference to the authorized patent number CN218769107U, a utility model patent discloses an anti-falling electrolytic capacitor, including a protective shell, a capacitor body is installed inside the protective shell, a wire is arranged on the upper surface of the protective shell, an anti-falling component is arranged at the bottom of the protective shell, a temperature measuring component is installed on the left side of the protective shell, the anti-falling component includes a mounting groove, a rotating shaft is installed inside the mounting groove, a connecting rod is fixedly connected to the surface of the rotating shaft, a mounting plate is fixedly connected to the bottom end of the connecting rod, a sliding cavity is opened inside the mounting plate, a suction cup is arranged at the bottom of the mounting plate, and a sealing plate is installed inside the sliding cavity.

[0004] The above patent has the following technical defects in practical application: the above patent uses a suction cup as an anti-dropping fixing structure for the electrolytic capacitor, and the suction cup can generally only play a temporary fixing role. When the air port enters the inside of the suction cup, the adsorption force will be immediately lost. In addition, when the suction cup is used, when the electrolytic capacitor produces lateral slippage, the suction cup cannot play a good fixing role. In summary, the suction cup fixing method is unstable for the anti-dropping of the electrolytic capacitor and has poor practicality. For this reason, we propose an anti-dropping electrolytic capacitor to solve the above technical defects. Utility Model Content

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1-Figure 5 ,in, Figure 1 A three-dimensional structure diagram of an anti-drop electrolytic capacitor proposed in the utility model Figure 1 ; Figure 2 A three-dimensional structure diagram of an anti-drop-off installation mechanism for an anti-drop-off electrolytic capacitor proposed in the utility model Figure 1 ; Figure 3 A three-dimensional structure diagram of an anti-drop-off installation mechanism for an anti-drop-off electrolytic capacitor proposed in the utility model Figure 2 ; Figure 4 This is a schematic cross-sectional structure diagram of an anti-drop-off installation mechanism for an anti-drop-off electrolytic capacitor proposed in the utility model; Figure 5 for Figure 4 An anti-drop-off electrolytic capacitor comprises: a base 1, an electrolytic capacitor outer protective cover 2 is arranged on the base 1, an electrolytic capacitor body is arranged inside the electrolytic capacitor outer protective cover 2, an electrode interface 3 is installed on the upper side of the electrolytic capacitor outer protective cover 2, and an anti-drop-off installation mechanism 4 is arranged between the base 1 and the electrolytic capacitor outer protective cover 2.

[0025] In this embodiment, the anti-falling mounting mechanism 4 includes a cylinder seat 41 and a mounting seat 47. The cylinder seat 41 is fixedly mounted on the base 1. A threaded rod 42 is screwed on the inner side of the cylinder seat 41. A threaded groove 45 matching the threaded rod 42 is opened on the inner side of the cylinder seat 41. A sliding push block 44 is rotatably mounted on the upper end of the threaded rod 42. The fixing rod of the mounting seat 47 is installed at the bottom of the outer protective cover 2 of the electrolytic capacitor. A plug-in groove 48 is opened on the inner side of the mounting seat 47. A sliding cavity 46 is opened inside the cylinder seat 41. A sliding groove 410 is opened on the side of the sliding cavity 46. A lateral slider 411 is slidably installed inside the sliding groove 410. A rebound mechanism is set at the bottom of the lateral slider 411. The sliding push block 44 is a quadrangular pyramid structure. The cross section of the sliding cavity 46 is rectangular. The inner wall of the sliding cavity 46 is in sliding contact with the sliding push block 44.

[0026] Through the above-mentioned arrangement, the cross-section of the sliding cavity 46 is designed to be rectangular, and the inner wall of the sliding cavity 46 is in sliding contact with the sliding push block 44. The sliding cavity 46 limits the rotational freedom of the sliding push block 44. When the threaded rod 42 rotates, the sliding push block 44 can be driven to slide inside the sliding cavity 46 through the screw transmission action with the cylinder seat 41. In addition, the sliding push block 44 is set as a quadrangular pyramid, and the cross-sectional area is in an increasing state from bottom to top. When the threaded rod 42 drives the sliding push block 44 to move upward, the side of the sliding push block 44 directly pushes the lateral slider 411 to move toward the outside of the sliding groove 410, so that the lateral slider 411 slides and is inserted into the inner side of the insertion groove 48 to form a clamping and fixing effect.

[0027] In this embodiment, the rebound mechanism includes a rebound bottom groove 412 and a lower ear seat 413. The rebound bottom groove 412 is opened at the bottom of the slide groove 410, and the lower ear seat 413 is fixedly installed at the bottom of the lateral slider 411. A pull-back spring 414 is fixedly connected between the lower ear seat 413 and the rebound bottom groove 412.

[0028] By the arrangement in the above manner, when the threaded rod 42 is rotated in the opposite direction to drive the sliding push block 44 to move downward, the rebound mechanism arranged at the bottom of the lateral slider 411 plays a rebound role. In the rebound mechanism, the rebound force of the rebound spring 414 acts on the lateral slider 411 through the lower ear seat 413, and pulls the lateral slider 411 back to the inside of the slide groove 410, so that when the threaded rod 42 drives the sliding push block 44 to move downward in the slide cavity 46, the lateral slider 411 can automatically pull back, thereby realizing the convenience of disassembly.

[0029] In this embodiment, four sets of anti-falling installation mechanisms 4 are provided and the anti-falling installation mechanisms 4 are located at the four corners of the bottom of the electrolytic capacitor outer protective cover 2 .

[0030] By the above arrangement, the anti-falling installation mechanism 4 is arranged at the four corners of the bottom of the electrolytic capacitor outer protective cover 2, realizing four-point clamping and fixing, limiting the rotational freedom, making the installation of the electrolytic capacitor body more stable and preventing it from falling off.

[0031] In this embodiment, a round hole is formed on the side of the threaded rod 42, and a transverse insertion rod 43 is inserted into the round hole.

[0032] By means of the above arrangement, the transverse insertion rod 43 is inserted into the inner side of the circular hole, so that it is easier to twist the threaded rod 42 by holding the transverse insertion rod 43 .

[0033] In this embodiment, four lateral sliding blocks 411 are evenly spaced along the circumference of the cartridge seat 41 .

[0034] Through the arrangement in the above manner, four lateral sliders 411 are evenly arranged, which increases the insertion points between the upper end of the cartridge seat 41 and the internal insertion groove 48 of the mounting seat 47, making the insertion more stable and preventing it from falling off.

[0035] In this embodiment, a cushion block 49 is installed on the inner wall of the plug-in slot 48, and the cushion block 49 is arranged in an L-shaped circle.

[0036] By the above-mentioned arrangement, the pad 49 is arranged so that a tight buffer zone is formed between the lateral slider 411 and the inner side of the plug-in slot 48, so that there is no gap at the plug-in point of the lateral slider 411 inside the plug-in slot 48, thereby avoiding shaking of the plug-in point and causing unstable plug fixation.

[0037] The working principle of an anti-drop-off electrolytic capacitor provided by the utility model is as follows:

[0038] During use, when installing the electrolytic capacitor body, align the mounting seat 47 at the bottom of the electrolytic capacitor outer protective cover 2 with the cartridge seat 41 on the base 1, so that the upper side end of the cartridge seat 41 is inserted into the mounting seat 47, and the threaded rod 42 is rotated to drive the sliding push block 44 to slide into the sliding cavity 46. Since the sliding push block 44 is a quadrangular pyramid, the sliding push block 44 can push the lateral slider 411 set on the side out of the slide groove 410. Then, under the push of the side wall of the sliding push block 44, the lateral slider 411 slides out of the slide groove 410 and is inserted into the inner side of the plug-in groove 48 set on the inner side of the mounting seat 47, forming a snap-fitting effect, and the anti-fall-off mounting mechanisms 4 at the four corners are all completed. When the lateral slider 411 is fixedly connected, the fixing work of the bottom of the electrolytic capacitor body is completed. When it is necessary to disassemble, the threaded rod can be rotated in the opposite direction to drive the sliding push block 44 to move downward. At this time, the rebound mechanism arranged at the bottom of the lateral slider 411 plays a rebound role. In the rebound mechanism, the rebound force of the rebound spring 414 acts on the lateral slider 411 through the lower ear seat 413, and the lateral slider 411 is pulled back to the inside of the slide groove 410, thereby releasing the clamping and fixing effect of the lateral slider 411 on the inner side of the plug-in groove 48. As a result, when the threaded rod 42 drives the sliding push block 44 to move downward in the slide cavity 46, the lateral slider 411 can automatically pull back, thereby realizing the convenience of disassembly.

[0039] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
