Description

Technical Field

[0001] This utility model relates to the field of waterproof power supply technology, and in particular to a waterproof power supply structure. Background Technology

[0002] With the rapid development of outdoor electronic equipment, industrial automation equipment and new energy fields, waterproof power supplies, as core power supply components, are widely used in harsh environments such as LED lighting systems, electric vehicle charging piles, and underwater detection equipment.

[0003] The waterproof power supply structure commonly used in the industry currently includes a housing and cover plates located at both ends of the housing. The two cover plates have inlet and outlet holes respectively, and input and output lines are installed at the inlet and outlet holes. The inner ends of the input and output lines are connected to the circuit board located inside the housing through male and female connectors. Sealing rings are set between the input and output lines and the inlet and outlet holes respectively. The sealing rings are bonded to the cover plates. After a period of use, the adhesive fails, and gaps or even cracks appear between the sealing rings and the cover plates, affecting the waterproof effect. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a waterproof power supply structure that can effectively seal the inlet and outlet holes, has a stable structure, and is easy to use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A waterproof power supply structure includes a housing and cover plates located at both ends of the housing. The housing and cover plates form a cavity for accommodating a circuit board. The cover plates have wiring holes through which power lines pass and are connected to the circuit board.

[0007] A rubber reinforcement is fixed on the power cord. A cylinder protrudes from the cover. A protruding ring protrudes from the end of the cylinder away from the cover. A retaining sleeve is fixed to the end of the rubber reinforcement near the cover. A rigid retaining plate is fixed inside the retaining sleeve. A through hole is provided through the retaining plate. The protruding ring and retaining plate are located inside the retaining sleeve. The protruding ring, retaining plate and retaining sleeve are connected by a connecting structure.

[0008] In this way, during the assembly process, the rubber reinforcement and the sleeve are integrally formed with the outer sheath of the power cord. The clamp plate is fixed inside the sleeve. The inner end of the power cord is passed through the through hole and wiring hole of the clamp plate and connected to the circuit board. The protruding ring is placed inside the sleeve. The connecting structure is used to fix the protruding ring, clamp plate and sleeve together. The protruding ring, clamp plate and sleeve are arranged outward to form a multi-level waterproof, which improves the waterproof effect.

[0009] The connecting structure includes two semi-rings forming a circular ring. The two semi-rings are located on the outside of the cylinder. A nut is fixed on each semi-ring. A through hole is opened in the threaded hole of the semi-ring opposite the nut. A light hole is opened in the sleeve, the convex ring and the clamping plate opposite the through hole. The locking bolt passes through the light hole and the through hole and is connected to the nut.

[0010] The convex ring has an annular groove on the side facing the card plate, and a sealing ring is fixed in the annular groove, which abuts against the card plate.

[0011] The rubber reinforcement and the ferrule are integrally formed.

[0012] A sealing gasket is provided between the housing and the cover, and the housing and the cover are fixedly connected by screws.

[0013] In summary, this waterproof power supply structure has the advantages of effectively sealing the inlet and outlet holes, having a stable structure, and being easy to use. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0020] like Figure 1-5As shown, a waterproof power supply structure includes a housing 1 and a cover 2 located at both ends of the housing. The housing and the cover form a cavity for accommodating a circuit board. The cover has a wiring hole, through which a power line 3 passes and is connected to the circuit board.

[0021] A rubber reinforcing part 4 is fixed on the power cord. A cylinder 5 protrudes from the cover. A protruding ring 6 protrudes outward from the end of the cylinder away from the cover. A retaining sleeve 7 is fixed to the end of the rubber reinforcing part near the cover. A rigid retaining plate 8 is fixed inside the retaining sleeve. A through hole is provided through the retaining plate. The protruding ring and the retaining plate are located inside the retaining sleeve. The protruding ring, the retaining plate, and the retaining sleeve are connected by a connecting structure.

[0022] In this way, during assembly, the rubber reinforcement and the retaining sleeve are integrally formed with the outer sheath of the power cord. The retaining plate is fixed inside the retaining sleeve. The inner end of the power cord passes through the through hole and wiring hole of the retaining plate and connects to the circuit board. The protruding ring is placed inside the retaining sleeve, and the connecting structure securely connects the protruding ring, retaining plate, and retaining sleeve. The outwardly positioned protruding ring, retaining plate, and retaining sleeve form a multi-level waterproof structure, improving the waterproof effect. The retaining plate can be made of rubber to provide support for the retaining sleeve.

[0023] In implementation, the connecting structure includes two semi-rings 9, which form a circular ring. The two semi-rings are located on the outside of the cylinder. Nuts 10 are fixed to the semi-rings. Through holes are formed in the threaded holes of the semi-rings opposite the nuts. Slippers, convex rings, and retaining plates have open holes opposite the through holes. Locking bolts 11 pass through the open holes and through holes and are connected to the nuts. Placing the two semi-rings on the outside of the cylinder and connecting them to the nuts with the locking bolts through the open holes and through holes achieves fixation and facilitates assembly.

[0024] In implementation, an annular groove 12 is formed on the side of the convex ring facing the clamping plate, and a sealing ring is fixed in the annular groove, which abuts against the clamping plate. The sealing ring further seals the convex ring and the clamping plate, improving the waterproofing effect.

[0025] In practice, the rubber reinforcement and the ferrule are integrally molded, facilitating manufacturing. Both the rubber reinforcement and the ferrule are made of rubber, possessing elastic deformation capabilities, which facilitates the insertion of the clamping plate and the convex ring into the ferrule.

[0026] In practice, a sealing gasket is provided between the housing and the cover, and the housing and cover are fixedly connected by screws. This improves the waterproof effect and facilitates the connection between the housing and the cover.

[0027] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
