Description

Capacitor Holder {CAPACITOR HOLDER}

The present invention relates to a capacitor holder, in particular a holder for mounting a plurality of capacitors on a circuit board.

Capacitors are widely used for charge storage, AC filtering, bypassing, smoothing, and blocking of DC signals. Different capacitors have different properties suitable for different functions and applications. In particular, electrolytic capacitors have high electrostatic storage capacity and low manufacturing cost. Electrolytic capacitors are therefore suitable for a wide range of applications, including telecommunications and electronic applications such as power supplies, motherboards, surveillance cameras and audio players.

Generally, electrolytic capacitors are installed on a circuit board by plugging leads into pre-arranged holes on the circuit board. The electrolytic capacitor is soldered to the circuit board in a tin solder furnace. In order to prevent falling away from the circuit board, spot adhesion is applied between the electrolytic capacitor and the circuit board. However, the spot adhesion process is often inefficient and the binder can peel off, resulting in an unstable installation of the electrolytic capacitor.

To solve this problem, the present inventors present a new solution.

It is an object of the present invention to provide a holder for safely mounting a plurality of capacitors.

The electrolytic capacitor includes a body in which two electrical leads are located at one end. The holder for the electrolytic capacitor includes a body structure, a top plate and a plurality of side plates extending downward from the top plate. The top plate has a plurality of slots, each slot holding one end of the electrolytic capacitor, ie the opposite end of the electrical lead. The body of each electrolytic capacitor is partially highlighted above the top surface of the top plate. Moreover, the side plates extend downward to form a plurality of latches. Each latch includes an extension and a fastening member.

The present invention has the following advantages.

1. The plurality of capacitor holders of the present invention provide excellent mounting stability. Moreover, no spot bonding is required, and the holder can be easily installed in a short time, thereby reducing labor costs.

2. The tightness of the capacitor holder shows an excellent ability, in particular for the conservation of space in the vertical direction.

3. In the case of capacitor explosion due to current overload, the capacitor holder can act as a barrier against explosion, minimizing potential secondary damage.

The above drawings and the following detailed description are examples for the purpose of better illustrating the scope of the present invention. Other objects and advantages related to the present invention will be described in the detailed description and the accompanying drawings.

See FIGS. 1-3. The present invention provides a holder 1 for mounting a plurality of electrolytic capacitors. The holder 1 is preferably made of plastic. The holder 1 comprises a body structure 10 and a plurality of latches 16.

The body structure 10 is composed of an upper plate 11 and a plurality of side plates 12 and 13. The front portion of the top plate 11 forms a plurality of holding slots 15 extending from below the bottom surface of the top plate 11 to the top surface 111 of the top plate.

The latching member 16 is located on the body structure 10 close to the side plates 12, 13. Each latching member 16 has an extension 161 and a fastening member 162. The extension 161 faces downward with respect to the top board 11. The outside of the end of the extension 161 protrudes laterally and is located below the bottom edge of the side plates 12, 13.

The number of side plates 12, 13 and latches 16 depends on the operating requirements and is therefore not limiting. In this embodiment, the side plate 12 extends down from the rear of the top plate 11. The side plates 13 extend downward on the right and left sides of the top plate 11, respectively. Therefore, the total number of side plates 12 and 13 is three in this embodiment. Thus, a total of three latches 16 are located near the side plates 12 and 13 away from the body structure.

Moreover, the upper half of the extension 161 of each latch 16 is integrally formed as part of the side plates 12 and 13. The lower half of the extension 161 extends from the bottom edge of the side plates 12 and 13. Alternatively, the upper half of the extension 161 of the latch 16 may also be spaced apart from the side plates 12 and 13 (not shown). The above-mentioned components constitute a plurality of holders 1 for the electrolytic capacitor of the present invention.

Reference is made to FIGS. 4 to 6, which show a holder 1 for mounting a plurality of electrolytic capacitors (ie EC capacitors, EC CAP: 3) on the circuit board 2. Each electrolytic capacitor 3 comprises a body 31 and three electrical leads 32 located at one end of the body 31. Parallel to the horizontal plane, the body 31 is cylindrical with two opposing ends, namely a first end 311 and a second end 312. Each of the bodies 31 is aligned with the corresponding slot 15 of the holder 1. The electrical lead 32 is electrically connected to the main body 31 at the first end 311. The two electrical leads 32 have different polarities and have the same or different lengths in dimensions.

In order to plug the electrical leads 32, the circuit board 2 has a plurality of through holes 21. The circuit board 2 also has a plurality of slits 22 for correspondingly matching the latching members 16. When mounting the electrolytic capacitor 3, the electrical leads 32 are plugged into the through holes 21 on the circuit board 2. Next, the electrical leads 32 are soldered to the circuit board 2 and are safely and electrically connected.

When mounting a plurality of holders for electrolytic capacitors, the extension 161 of the latch 16 penetrates the slit 22 of the circuit board 2. The fastening member of the latch 16 is in close contact with the bottom surface 202 of the circuit board 2 (see FIG. 8). Bottom edges of the side plates 12 and 13 are in close contact with the upper surface 201 of the circuit board 2. The fixing mechanism allows the holder 1 for the plurality of electrolytic capacitors to be securely mounted on the circuit board 2.

For the main body 31 and the opposing electric leads 32, the upper surface of the second end 312 is fixed by the top plate 11 of the holder 1. The lower surface of the main body 31 is fixed below by the circuit board 2. The body 31 of each electrolytic capacitor is partly above the top surface 111 of the top plate 11. In other words, the upper surface 111 of the upper plate 11 is slightly below the outer surface of the body 31.

Reference is again made to FIGS. 1 and 2. Each slot 15 is defined by a distal wall 151 and a pair of side walls 152. The outer surface of the body 31 is partially fixed by the side wall 152.

In addition, the side wall 152 of each slot 15 may have a curved surface to fit around the outer surface of the body 31.

See FIG. A plurality of holders for electrolytic capacitors 1 are located near the second end 312 of the body 31. For each slot 15, the distal wall 151 and the end face 3121 of the second end 312 are spaced by the distance D. Therefore, even if the electrolytic capacitor explodes due to overcurrent, the body structure 10 serves as a barrier to suppress the explosion, thereby minimizing the explosion effect.

See FIGS. 4, 7 and 8. For each body 31 of the capacitor, a corresponding opening 23 is located on the circuit board 2. Through each opening 23, the body 31 rests on the circuit board 2 and is partially highlighted from the bottom surface 202.

Therefore, the present invention of the holder for the plurality of electrolytic capacitors has the following functions and features.

1. Through the top plate and the plurality of slots, the holder for the plurality of electrolytic capacitors according to the present invention allows to protect the body of each electrolytic capacitor at opposite ends of the electrical leads. Instead, no spot bonding is required, and the side plates and latches can be easily installed in a short time by allowing the holder to be easily installed in a short time, thereby reducing labor costs.

2. In the present invention of a holder for a plurality of electrolytic capacitors, the upper surface of the upper plate is slightly lower than the outer surface of the main body of the electrolytic capacitor, so that the capacitors lie horizontally. Therefore, the holder does not occupy additional space in the vertical direction above the capacitor.

3. A plurality of holders for the electrolytic capacitors are located near the second end of the body. Even if the electrolytic capacitor explodes due to overcurrent, the body structure of the holder will act as a barrier to suppress the explosion, thereby minimizing the explosion effect.

The foregoing description is a preferred embodiment of the present invention, and the features of the present invention are by no means limited thereto. All changes, alternatives, or improvements that are generally conceivable by those skilled in the art are deemed to be within the scope of the present invention as defined in the appended claims.
