[0002] Capacitors are usually called capacitors, which are also called "capacitance". They refer to the amount of charge stored under a given potential difference. Generally speaking, charges will move under force in an electric field. When there is a medium between conductors, the movement of charges is hindered and the charges accumulate on the conductors, resulting in the accumulation of charges. The amount of stored charge is called capacitance.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 8As shown, the utility model provides a film capacitor that is easy to install, including a capacitor body 2, a protective box 1 is sleeved on the outer side of the capacitor body 2, an elastic support member 3 for supporting the capacitor body 2 is provided at the bottom end of the inner side of the protective box 1, and both sides of the protective box 1 are provided with a limiter 4 that limits the upward translation of the capacitor body 2 by sliding with the capacitor body 2, and the other two sides of the protective box 1 are provided with a clamping mechanism 5 for clamping the capacitor body 2. By placing the capacitor body 2 inside the protective box 1 and supporting it through the elastic support member 3, and then squeezing the capacitor body 2 downward to make it cooperate with the limiter 4, the limiter 4 can limit the upward movement of the capacitor body 2, thereby realizing the rapid installation of the capacitor body 2.

[0025] The elastic support member 3 includes a support plate 31, which is slidably connected to the bottom end of the inner side of the protection box 1, and springs 1 32 are welded at both ends of the bottom of the support plate 31. The bottom ends of the two springs 1 32 are welded to the bottom wall of the inner side of the protection box 1, and both ends of the support plate 31 are provided with assembly grooves 33 corresponding to the pins of the capacitor body 2, and the pins of the capacitor body 2 are slidably matched with the corresponding assembly grooves 33. During installation, the capacitor body 2 is placed on the support plate 31, and the capacitor body 2 is pressed downward to apply pressure to the support plate 31, which makes the support plate 31 slide downward and apply pressure to the spring 1 32, so that the spring 1 32 is compressed and accumulates potential energy, and then the capacitor body 2 is matched with the limiter 4, so that the capacitor body 2 is installed; by separating the limiter 4 from the capacitor body 2, the spring 1 32 releases the potential energy, so that the capacitor body 2 pops up to achieve rapid pop-up, which can facilitate the placement and removal of the capacitor body 2.

[0026] Among them, the limiting member 4 includes a pull rod 41, which passes through the side wall of the protection box 1 and is slidably connected to the side wall of the protection box 1. One end of the pull rod 41 is fixedly connected to a wedge-shaped limiting block 42. Both sides of the capacitor body 2 are provided with a slot 21 that slides with the wedge-shaped limiting block 42. The other end of the pull rod 41 is fixedly connected to a pull block 43. A spring 44 is sleeved on the pull rod 41. One end of the spring 44 contacts the wedge-shaped limiting block 42, and the other end of the spring 44 contacts the inner wall of the protection box 1. When the capacitor body 2 is squeezed downward to move downward, the slot 21 of the capacitor body 2 will cooperate with the wedge-shaped limit block 42, and the wedge-shaped limit block 42 will limit the upward movement of the capacitor body 2; when disassembling, the pull block 43 is pulled outward to make the pull rod 41 slide outward, which makes the wedge-shaped limit block 42 disengage from the slot 21. At this time, the capacitor body 2 is no longer restricted and pops up upward under the elastic force of the spring 32, thereby realizing the rapid removal of the capacitor body 2.

[0027] Among them, the clamping mechanism 5 includes a sliding rod 51, one end of which is provided with an elastic clamp 52 for buffering the capacitor body 2, and the other end of the sliding rod 51 is fixedly provided with an adjusting member 53 for driving the sliding rod 51 to slide; the elastic clamp 52 includes a mounting plate 521 on one side of which is fixedly connected to the sliding rod 51, and the other side of the mounting plate 521 is fixedly connected with a sliding block 522, one end of the sliding block 522 is slidably connected with a clamping plate 523, the inner side of the clamping plate 523 is slidably connected with a guide plate 524, the guide plate 524 is fixedly connected to the end of the sliding block 522, and springs 525 are welded at both ends of the guide plate 524, and the ends of the two springs 525 away from the guide plate 524 are in contact with the inner wall of the clamping plate 523.

[0028] The adjusting member 53 includes a connecting rod 531, one end of which is hinged to the sliding rod 51, and the other end of the connecting rod 531 is hinged to a connecting seat 532. A fixing plate 533 is fixedly connected to the top of the outer side of the protection box 1, and an adjusting bolt 534 that passes through the fixing plate 533 is threadedly connected to the fixing plate 533. The bottom end of the adjusting bolt 534 is rotatably connected to the top of the connecting seat 532.

[0029] By rotating the adjusting bolt 534, the connecting seat 532 can be translated downward, which makes the connecting rod 531 apply a thrust to the sliding rod 51, so that the sliding rod 51 drives the mounting plate 521 to approach the capacitor body 2, which makes the clamping plate 523 contact with the capacitor body 2, so that the clamping plate 523 can clamp the capacitor body 2 to improve the overall stability; and the elastic properties of the spring three 525 itself can provide a buffering force for the capacitor body 2, so that the spring three 525 can buffer the capacitor body 2 when the protective box 1 is impacted, thereby avoiding damage to the capacitor body 2.
