Description

Technical Field

[0001] This application relates to the technical field of power supply devices, and particularly to a rubber plug and a power supply device. Background Art

[0002] Power supply devices are widely used in production and daily life to provide power supply for multiple electrical appliances. For power supply devices such as UPS, Inverter, and AVR, rubber plugs are often used for dust prevention, fixing of accessories, etc.

[0003] However, currently existing rubber plugs usually need to be designed differently for different power supply devices, resulting in a large number of rubber plugs with different shapes and specifications. This not only causes the non - shareability of rubber plugs but also increases the difficulty of selecting and adapting the rubber plugs. Utility Model Content

[0004] In view of this, this application provides a rubber plug and a power supply device that can be compatible with different hole diameters.

[0005] In a first aspect, this application provides a rubber plug for use in a power supply device. The power supply device is provided with a number of jacks having one or more hole diameters. The rubber plug includes a plug cover and a plug body extending from one side of the plug cover. The plug body is for insertion into the number of jacks. The plug body is provided with a through - hole that penetrates the plug body, which is used to increase the deformation amount when the plug body is inserted into the number of jacks, so that the plug body can be adapted to the number of jacks with one or more hole diameters.

[0006] The plug body is further sequentially provided with an anti - detachment portion and a guiding portion. The anti - detachment portion is connected to the plug cover. The diameter of the guiding portion gradually decreases. The anti - detachment portion includes a first anti - detachment portion, a second anti - detachment portion, and a third anti - detachment portion protruding from the side of the first anti - detachment portion. Among them, the diameters of the first anti - detachment portion and the second anti - detachment portion both gradually increase, and the diameter growth rate of the second anti - detachment portion is greater than that of the first anti - detachment portion.

[0007] Further, the rubber plug is symmetrically arranged.

[0008] Further, the through - hole is in a long - strip shape, and the long - strip through - hole sequentially penetrates the first anti - detachment portion, the second anti - detachment portion, and the guiding portion to increase the deformation amounts of the first anti - detachment portion, the second anti - detachment portion, and the guiding portion.

[0009] Further, the plug body further includes a hole wall enclosing the long - strip through - hole. One side of the hole wall close to the first anti - detachment portion is a planar structure. The other side of the hole wall close to the guiding portion is an arc - surface structure.

[0010] Further, the third anti - detachment portion is in the shape of an inverted triangular pyramid.

[0011] Further, the number of the third anti - detachment parts is two, and the two third anti - detachment parts are symmetrically arranged on two opposite sides of the first anti - detachment part.

[0012] Further, the third anti - detachment part has easy - to - press deformability; when the plug body is inserted into a jack with a large aperture, the third anti - detachment part engages with the large - aperture jack so that the plug body fits the large - aperture jack; when the plug body is inserted into a jack with a small aperture, the third anti - detachment part is squeezed and deformed by the small - aperture jack so that the plug body fits the small - aperture jack.

[0013] Further, the plug body is generally in the shape of a semi - cone.

[0014] Further, the other end of the plug cover away from the plug body is in a dome shape.

[0015] In a second aspect, the present application provides a power supply device, which includes: a plurality of jacks with one or more apertures; and a rubber plug inserted into the plurality of jacks.

[0016] For the above - mentioned rubber plug and power supply device, when a positive pressing force is applied, the plug body is smoothly embedded into the jack through the guiding part of the cone structure. The anti - detachment part clamps the jack to prevent the rubber plug from falling out of the jack. And through the third anti - detachment part convexly arranged on the side of the first anti - detachment part, the plug body is further clamped tightly in the jack. When a negative pulling force is applied, the first anti - detachment part with an inverted cone structure disperses stress to reduce the risk of the rubber plug falling off due to stress concentration. In addition, by providing a through - hole penetrating the inside of the plug body, the deformation amount of the plug body is increased so that the plug body can fit more jacks with different apertures, thereby increasing the common use of the rubber plug.

[0037] Please refer to Figure 1 , Figure 1 which is a schematic three-dimensional structure diagram of the rubber plug provided by an embodiment of this application. This application provides a rubber plug 100, which is applied to a power supply device 1000 and is used to fix accessories and block holes of the power supply device 1000. Specifically, the power supply device 1000 includes a number of jacks 200 with one or more apertures. The rubber plug 100 includes a plug cover 1 and a plug body 2 extending from one side of the plug cover. The plug body 2 is inserted into the power supply device 1000 through the number of jacks 200, and the plug cover 1 remains exposed outside the power supply device 1000. Preferably, the rubber plug 100 in this application needs to have good heat resistance, elasticity, wear resistance, and sealing performance, etc., so that the rubber plug 100 can be adapted to more application scenarios. Correspondingly, the rubber plug 100 can be made of any material that meets the above requirements, such as rubber, silicone, etc., which is not limited herein.

[0038] The rubber plug 100 is symmetrically arranged. Correspondingly, the plug cover 1 and the plug body 2 are symmetrically arranged. One end of the plug cover 1 is flat, which is used to extend out of the plug body 2, and the other end of the plug cover 1 away from the plug body 2 is dome-shaped, so as to facilitate the removal of the rubber plug 100. At the same time, when subjected to external pressure or impact, the dome-shaped design can more effectively disperse stress, reduce the risk of damage to the plug cover 1, and thus extend the service life of the rubber plug 100. In this embodiment, the plug cover 1 covers the jack 200 to cover some local appearances that need to be shielded, and at the same time can also achieve the function of dust-proof plugging holes, so that dust and other impurities cannot be inhaled into the power supply device 1000.

[0039] Please refer to Figure 4 , Figure 4 , which is a schematic bottom view structure of the rubber plug provided by an embodiment of the present application. The plug body 2 is generally in the shape of a semi-cone. It can be understood that the plug body 2 in this embodiment is not a complete cone, but is equivalent to cutting off a part along the direction perpendicular to the plug cover 1 (equivalent to the bottom surface of the cone). The specific amount of cutting can be flexibly designed. Preferably, the amount of cutting is less than or equal to half of the complete cone. This cutting method does not change the diameter of the bottom surface of the cone, so that the rubber plug 100 with a semi-cone design can still be adapted to the jack 200 with the same hole diameter size as the rubber plug 100 with a complete cone design. And compared with the complete cone design, the half-cone design reduces unnecessary material consumption and reduces the production cost of the rubber plug 100. The specific structure of the plug body 2 will be further introduced below.

[0040] Please refer to Figure 5 , Figure 5 , which is a schematic partial structure diagram of the power supply device provided by an embodiment of the present application. The plug body 2 is provided with an anti-detachment part 21, a guiding part 22, and a through hole 23. The anti-detachment part 21 and the guiding part 22 are sequentially arranged on the plug body 2, and the anti-detachment part 21 is connected to the plug cover 1. The guiding part 22 is used to guide the plug body 2 to be inserted into the jack 200, and the anti-detachment part 21 is used to prevent the rubber plug 100 from falling off. The through hole 23 penetrates the plug body 2 and is used to increase the deformation amount when the plug body 2 is inserted into a plurality of jacks 200, so that the plug body 2 can be adapted to a plurality of jacks 200 with one or more hole diameters.

[0041] Furthermore, the diameter of the guiding part 22 gradually decreases. That is, the guiding part 22 adopts a cone structure. On the one hand, the design of the cone structure can play a guiding role during the embedding installation, so that the plug body 2 can enter the jack 200 more smoothly. On the other hand, as the cone structure gradually penetrates into the jack 200, the diameter of the cone structure gradually increases. This gradually compressed design helps the rubber plug 100 to gradually adapt to the shape and size of the jack 200 during the embedding installation, which is beneficial to the embedding installation.

[0042] The anti - detachment part 21 includes a first anti - detachment part 211, a second anti - detachment part 212, and a third anti - detachment part 213 protruding from the side of the first anti - detachment part 211. Specifically, the jack 200 includes a hole wall 201 surrounding the jack 200 and an inner edge 202. When the plug body 2 is fully inserted into the jack 200, the first anti - detachment part 211 is in interference fit with the hole wall 201, and the rubber plug 100 is clamped to the hole wall of the jack 200 through the third anti - detachment part 213. And when the plug body 2 is fully inserted into the jack 200, the inner hole edge of the jack 200 abuts against the second anti - detachment part 212, so that the second anti - detachment part 212 clamps the jack 200, thereby preventing the rubber plug 100 from falling off the jack 200.

[0043] The diameters of both the first anti - detachment part 211 and the second anti - detachment part 212 gradually increase, and the diameter growth rate of the second anti - detachment part 212 is greater than that of the first anti - detachment part 211. That is, the first anti - detachment part 211 adopts an inverted cone structure. When the rubber plug 100 is pulled by an external force, the inverted cone structure can effectively disperse the stress, avoid stress concentration in one direction, and thus reduce the risk of detachment caused by stress concentration. It can be understood that the greater the diameter growth rate of the second anti - detachment part 212, the greater the inclination angle of the second anti - detachment part 212, and at the same time, it also means that the included angle between the second anti - detachment part 212 and the inner hole edge of the jack 200 is larger. Under the same pulling force, the larger the included angle between the second anti - detachment part 212 and the inner hole edge of the jack 200, the greater the reaction force of the inner hole edge of the jack 200 on the second anti - detachment part 212 in the pulling force direction, and thus the difficulty of the rubber plug 100 being pulled off and falling off by an external force is increased.

[0044] Please refer to Figure 3 , Figure 3 which is a schematic side - view structure diagram of the rubber plug provided by an embodiment of the present application. The third anti - detachment part 213 is in the shape of an inverted triangular pyramid, that is, as the plug body 2 gradually penetrates into the jack 200, the size of the third anti - detachment part 213 gradually increases. This design helps the third anti - detachment part 213 to gradually adapt to the shape and size of the jack 200 during the embedding installation, which is beneficial to the embedding installation of the rubber plug 100. In addition, the number of the third anti - detachment parts 213 can be designed according to actual needs. Preferably, the number of the third anti - detachment parts 213 is two, and the two third anti - detachment parts 213 are symmetrically arranged on the opposite sides of the first anti - detachment part 211.

[0045] Further, when the plug body 2 is inserted into the jack 200 with a large aperture, the third anti - detachment portion 213 is latched with the jack 200 with a large aperture, increasing the difficulty of the large rubber plug 100 being pulled off by an external force, and thus enabling the plug body 2 to be adapted to the jack 200 with a large aperture. In addition, the third anti - detachment portion 213 has easy - to - press deformability. Therefore, when the plug body 2 is inserted into the jack 200 with a small aperture, the third anti - detachment portion 213 is deformed by the small - aperture jack 200, so that the third anti - detachment portion 213 does not block the insertion of the plug body 2, avoiding assembly difficulties, and thus enabling the plug body 2 to be adapted to the jack 200 with a small aperture.

[0046] Please refer to Figure 2 , Figure 2 which is a front - view structural schematic diagram of the rubber plug provided by an embodiment of the present application. The through - hole 23 sequentially penetrates through the first anti - detachment portion 211, the second anti - detachment portion 212, and the guiding portion 22, and the through - hole 23 is designed in a long - strip shape that is wide in the middle and narrow at both ends in accordance with the diameter changes of the three. Among them, the relatively wider part in the middle provides a larger deformation space when the plug body 2 is squeezed, enabling the plug body 2 to more easily adapt to jacks 200 with different apertures. The design of being narrow at both ends helps, after the plug body 2 is inserted into the jack 200, to make the deformation mainly concentrated in the middle part while keeping both ends relatively stable. This characteristic of balanced deformation helps to ensure that the plug 12 can maintain a stable fixed state after insertion.

[0047] Further, the plug body 2 further includes a hole wall 231 enclosing the long - strip through - hole 23. The end of the hole wall 231 close to the first anti - detachment portion 211 is an arc - surface structure 233, which is beneficial for the first anti - detachment portion 211 to maintain stable deformation within a certain floating range at the corresponding position of the arc - surface structure 233. The other end of the hole wall 231 close to the guiding portion 22 is a flat - surface structure 232, which is beneficial for the guiding portion 22 not to be deformed easily at the corresponding position of the flat - surface structure 232, thereby enhancing the structural strength of the guiding portion 22 at the corresponding position.

[0048] In the above - mentioned embodiment, when a positive pressing force is applied, the plug body 2 is smoothly embedded into the jack 200 through the guiding portion 22 with a conical structure. The second anti - detachment portion 212 latches the jack 200 to prevent the rubber plug 100 from falling off the jack 200. And through the third anti - detachment portion 213 convexly provided on the side of the first anti - detachment portion 211, the plug body 2 is further clamped tightly in the jack 200. When a negative pulling force is applied, the first anti - detachment portion 211 with an inverted - conical structure disperses the stress to reduce the risk of detachment caused by stress concentration. In addition, by having a through - hole 23 penetrating through the plug body 2, the deformation amount of the plug body 2 is increased, enabling the plug body 2 to be adapted to more jacks 200 with different apertures, thereby increasing the common use of the rubber plug 100.

[0049] Please refer to Figure 6 , Figure 6The complete structural schematic diagram of the power supply device provided by an embodiment of the present application. The present application also provides a power supply device 1000, which includes a plurality of jacks 200 and a plurality of rubber plugs 100 inserted into the plurality of jacks 200 one by one. Among them, the plurality of jacks 200 can be one or more aperture sizes, such as 2.7 mm, 3.0 mm, 3.4 mm, etc. And the jacks 200 can be screw holes, through holes, etc. This is not limited here.

[0050] In the above embodiment, the rubber plug 100 can be used for the assembly and fixation of accessories (such as air duct paper, insulating sheet, etc.) in the power supply device 1000 to save additional fixing parts (such as screws, rivets, etc.). In one embodiment, the rubber plug 100 is used to fix the air duct paper to the heat sink. Specifically, the air duct paper is provided with air duct paper holes, and the heat sink is provided with heat dissipation holes. The rubber plug 100 passes through the air duct paper holes to fix the air duct paper to the heat sink, and then presses the plug body 2 through the heat dissipation holes, thereby clamping the rubber plug 100 to prevent the rubber plug 100 from falling off. In another embodiment, the rubber plug 100 is used to fix the insulating sheet to the PCBA circuit board. Specifically, the insulating sheet is provided with insulating sheet holes, and the PCBA circuit board is provided with through holes. The rubber plug 100 passes through the insulating sheet holes to fix the insulating sheet to the PCBA circuit board, and then uses the plug body 2 to buckle the through holes of the PCBA circuit board, thereby preventing the rubber plug 100 from falling off.

[0051] The above are only the preferred embodiments of the present utility model, but do not limit the patent scope of the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing specific embodiments, or perform equivalent replacements on some of the technical features. Any equivalent structure directly or indirectly using the content of the specification and drawings of the present utility model in other related technical fields shall be within the scope of the patent protection of the present utility model by the same token.
