Description

Technical Field

[0001] This application relates to the field of capacitor technology, and in particular to a capacitor for a mahjong machine. Background Technology

[0002] Capacitors are components that store electrical charge and electrical energy (potential energy). In circuits, capacitors play a key role through their characteristics such as energy storage, phase shifting, filtering, and resonance. For example, starting capacitors work with the auxiliary winding of a motor to shift the phase and provide starting torque; running capacitors maintain the stable operation of the motor and improve the power factor; filtering capacitors smooth DC voltage and reduce ripple, which can ensure the normal operation of equipment and improve circuit stability and efficiency.

[0003] The shuffling motor and lifting motor in a mahjong machine require a large current to generate rotational torque when starting. Usually, the starting capacitor is connected in series with the auxiliary winding of the motor. The capacitor used in mahjong machines is generally a metallized polypropylene film capacitor. Metallized polypropylene film capacitors have the advantages of being non-polar, having high insulation resistance, wide frequency response, and very low dielectric loss.

[0004] Metallized polypropylene film capacitors typically consist of a casing and a capacitor core. The casing is usually made of PBT or plastic, while the capacitor core has gold plating at both ends and soldered leads or connecting wires. Epoxy resin is also filled into the casing for sealing. However, many existing mahjong machine capacitors have simple casing structures, making it difficult to secure the capacitor core after it is inserted, and they are inconvenient to process. Moreover, the capacitor core is only secured by the filled epoxy resin. Since the inner wall of the casing is smooth, once the epoxy resin ages, it affects the stability of the capacitor core and the performance. Therefore, it is necessary to design a mahjong machine capacitor that is easy to process and has a stable connection. Utility Model Content

[0005] This application provides a mahjong machine capacitor that is easy to process and provides a stable connection.

[0006] The technical solution for a mahjong machine capacitor provided in this application is as follows:

[0007] A capacitor for a mahjong machine includes a housing and a capacitor core disposed within the housing. A connecting portion is provided on the outer side of the housing, and a plurality of supporting portions are provided on the inner side of the housing. The supporting portions are vertically arranged along the inner sidewall of the housing. The capacitor core can be locked between the supporting portions. A gap is provided between the capacitor core and the bottom of the housing. The housing is filled with sealant, which encapsulates the capacitor core. Leads are provided on the capacitor core, and the leads pass through the sealant.

[0008] Preferably, the connecting part is integrally formed with the housing, the connecting part is a plate-shaped structure and has fixing holes.

[0009] Preferably, the shell is a shell structure with a closed lower end, and the support portion is evenly distributed circumferentially along the bottom edge of the shell.

[0010] Preferably, the support part is a plate-shaped or strip-shaped structure, and the bottom of the support part is provided with an inwardly bent part, which can be connected to the bottom of the capacitor core.

[0011] Preferably, the side of the support portion closest to the capacitor core is an inclined surface, and the width of the lower part of the support portion is greater than the width of the upper part of the support portion.

[0012] Preferably, the upper part of the housing is provided with a guide portion, the inner side of the guide portion is provided with rounded corners or chamfers, and the lower end of the guide portion can be connected with the sealant.

[0013] Preferably, the guide portion is connected to the upper end of the housing, and the distance between the inner side of the guide portion and the capacitor core is not less than the distance between the inner side of the support portion and the capacitor core.

[0014] Preferably, there are multiple guide portions, and the positions of the guide portions correspond to the positions of the support portions, with the guide portions located directly above the support portions.

[0015] Preferably, the guide portion and the support portion are integrally formed.

[0016] Preferably, the guide portion is bent inward along the inner side of the upper end of the housing, the guide portion is an annular plate structure, and a gap is provided between the lower end of the guide portion and the support portion.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. This application provides a connecting part on the outside of the housing for easy connection and fixing of the capacitor; multiple support parts are vertically arranged along the side wall of the housing on the inside, which can clamp and fix the capacitor core, ensuring that the capacitor core will not move during subsequent operations such as potting and wiring, facilitating subsequent processing. At the same time, since there is a gap between the capacitor core and the bottom of the housing, the sealant potted inside the housing can completely wrap the capacitor core, and the sealant can also connect with the support parts on the inner side wall of the housing, thereby improving the connection stability between the capacitor core and the housing, preventing the capacitor core from falling off after the sealant ages, and ensuring the performance.

[0019] 2. By uniformly arranging the support portion along the bottom edge of the housing, the stability of the connection is improved; by setting the support portion as a plate or strip structure and setting a bend at the bottom of the support portion, the capacitor core can be supported, ensuring that the sealant can enter between the capacitor core and the bottom of the housing, thus ensuring connection stability; by setting the side of the support portion near the capacitor core as a slope, it is convenient to process and can ensure the support effect of the capacitor core.

[0020] 3. By providing a guide section on the upper part of the housing, it is easier to insert the capacitor core. At the same time, the lower end of the guide section is in contact with the sealant, which can further prevent the sealant from falling off after aging and improve the stability of the connection.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a capacitor for a mahjong machine.

[0029] Example 1:

[0030] Reference Figures 1 to 4 A capacitor for a mahjong machine includes a housing 1 and a capacitor core 2 disposed inside the housing 1. The housing 1 is a square housing structure with the lower end closed. A connecting part 101 is provided on the outer side of the housing 1. The connecting part 101 is integrally disposed with the housing 1. The connecting part 101 is a plate-shaped structure and is provided with fixing holes, which can be used to fix the capacitor during installation.

[0031] Reference Figures 2 to 4The inner side of the housing 1 is provided with a plurality of support portions 102, which are vertically arranged along the inner sidewall of the housing 1. Specifically, in this embodiment, the support portions 102 are evenly arranged circumferentially along the bottom edge of the housing 1. The capacitor core 2 can be locked between the support portions 102. There is a gap between the capacitor core 2 and the bottom of the housing 1. Specifically, in this embodiment, the support portion 102 is a plate-shaped or strip-shaped structure. The bottom of the support portion 102 is provided with an inwardly bent portion, which can be connected to the bottom of the capacitor core 2. The housing 1 is filled with sealant 3 and the capacitor core 2 is wrapped by the sealant 3. The capacitor core 2 is provided with pins 201 and the pins 201 pass through the sealant 3.

[0032] Reference Figures 2 to 4 The upper part of the housing 1 is provided with a guide part 103. The inner side of the guide part 103 is provided with rounded corners or chamfers. The lower end of the guide part 103 can be connected with the sealant 3. Specifically, there are multiple guide parts 103 and the position of the guide part 103 corresponds to the position of the support part 102. The guide part 103 is located directly above the support part 102 and is connected to the upper end of the housing 1. The distance between the inner side of the guide part 103 and the capacitor core 2 is not less than the distance between the inner side of the support part 102 and the capacitor core 2, so as to ensure that the capacitor core 2 can be placed into the housing 1.

[0033] Reference Figure 3 The guide part 103 and the support part 102 are integrally set. Specifically, the guide part 103 is bent inward along the inner side of the upper end of the housing 1. The guide part 103 is a ring plate structure. There is a gap between the lower end of the guide part 103 and the support part 102 to facilitate processing and ensure the guiding effect on the capacitor core 2. Combined with the support part 102 set on the inner side wall of the housing 1, the connection stability between the capacitor core 2 and the housing 1 can be improved, and the capacitor core 2 can be prevented from falling out after the sealant 3 ages, thus ensuring the performance.

[0034] Example 2:

[0035] Reference Figure 5 The difference between this embodiment and embodiment one is that the side of the support portion 102 near the capacitor core 2 in this embodiment is an inclined surface, and the width of the lower part of the support portion 102 is greater than the width of the upper part of the support portion 102. Specifically, the distance between the lower ends of the support portions 102 provided on the two parallel inner walls of the housing 2 is less than the size of the capacitor core 2, so as to ensure that there is a distance between the bottom of the capacitor core 2 and the bottom of the housing 1, and to ensure the connection stability between the sealant 3 and the capacitor core 2 and between the sealant 3 and the housing 1.

[0036] The implementation principle is as follows: This application provides a connecting part 101 on the outside of the housing 1 to facilitate the connection and fixation of the capacitor 2; multiple support parts 102 are vertically provided on the inner side of the housing 1 along the side wall of the housing, which can clamp and fix the capacitor core 2 through the support parts 102, ensuring that the capacitor core 2 will not move during subsequent operations such as potting and wiring, which facilitates subsequent processing. At the same time, since there is a gap between the capacitor core 2 and the bottom of the housing 1, the sealant 3 potted inside the housing can completely wrap the capacitor core 2, and the sealant 3 can also connect with the support parts 102 provided on the inner side wall of the housing 1, thereby improving the connection stability between the capacitor core 2 and the housing 1, preventing the capacitor core 2 from falling off after the sealant 3 ages, and ensuring the performance.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
