Description

TECHNICAL FIELD

DETAILED DESCRIPTION

[0031] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the person of ordinary skill in the art without making creative labor should belong to the protection scope of the present application.

[0032] The present application will be further described below in combination with the drawings.

[0033] Embodiment 1

[0034] As Figure 1 andFigure 2 The waterproof connector of the present application comprises a connector body 1, a sealing ring 2 fixedly installed on the outer surface of the connector body 1, a terminal 5 fixedly installed inside the connector body 1, a sealing gasket 3 installed on both sides of the connector body 1, and a pressing block 4 installed on both sides of the connector body 1, with the sealing gasket 3 located inside the pressing block 4.

[0035] The working principle of the embodiment 1 is that, in use, when the connector body 1 is inserted into an external socket, the sealing ring 2 can be attached to the inner wall of the socket, so that the sealing ring 2 can be located in the gap between the connector body 1 and the socket, thereby preventing water from entering between the connector body 1 and the socket. The connector body 1 is provided with a lock on both sides, which can be connected with the groove of the socket when the connector body 1 and the socket are in contact, so as to integrate the connector body 1 and the socket, thereby completing the work.

[0036] Embodiment 2

[0037] On the basis of the embodiment 1, as shown in Figure 3 , Figure 4 and Figure 5 , a socket 6 is slidingly installed at the front end of the connector body 1. The socket 6 comprises an alignment groove 7, a plastic gasket 8, a support base 9, an alignment shell 10, a limiting sleeve 11, a limiting spring 12, a first gear 13, a support shaft 14, and a protective cover plate 15. The alignment shell 10 is fixedly installed on the outer circle of the socket 6. The alignment groove 7 is formed in the inner side of the top end and the bottom end of the alignment shell 10. The plastic gasket 8 is fixedly installed in the inner side of the alignment groove 7. The support base 9 is symmetrically fixedly installed on the top end and the bottom end of the alignment shell 10. The limiting spring 12 is fixedly installed on the support base 9. The support shaft 14 is rotatably installed on the top and the bottom of the side end of the alignment shell 10 away from the plastic gasket 8. The first gear 13 is symmetrically fixedly installed on the outer circle of the support shaft 14. The protective cover plate 15 is fixedly installed on the outer circle of the support shaft 14, with the first gear 13 located at the bottom end of the protective cover plate 15. The limiting sleeve 11 is symmetrically fixedly installed on the top end and the bottom end of the alignment shell 10, and is located below the limiting spring 12. When the connector body 1 and the socket 6 are combined, the plug plate 27 can be inserted into the inner side of the alignment groove 7 and tightly attached to the plastic gasket 8, so that the plug plate 27 and the alignment groove 7 can form secondary protection on the outer surface of the sealing ring 2, thereby improving the waterproof performance.

[0038] As shown in Figure 6 , the limiting device 16 is symmetrically slidingly sleeved on the top end and the bottom end of the connector body 1. The guiding device 17 is fixedly installed on the outer circle of the connector body 1, which can support the positioning work of the limiting device 16.

[0039] As shown in Figure 7The limiting device 16 includes a contact piece 18, a movable rod 19, a positioning rod 20, a connecting crossbar 21, a first rack 22, a special-shaped bracket 23, and a reinforcing bracket 24. The special-shaped bracket 23 is fixedly installed on the top of the first rack 22, the reinforcing bracket 24 is fixedly installed on the top of the special-shaped bracket 23, the connecting crossbar 21 is fixedly installed on the end of the reinforcing bracket 24 away from the special-shaped bracket 23, the contact piece 18 is fixedly installed on both ends of the connecting crossbar 21, the movable rod 19 is fixedly installed at the center of the top of the contact piece 18, and the positioning rod 20 is fixedly installed at the center of the bottom end of the contact piece 18. The two first racks 22 are located on both sides of the second gear 34, so that when the second gear 34 rotates, it can drive the two first racks 22 to move upward or downward respectively.

[0040] like Figure 8 The guide device 17 includes a second rack 25, an alignment slide plate 26, and a mating insert plate 27. The alignment slide plate 26 is symmetrically fixedly installed at the top and bottom of the mating insert plate 27. The second rack 25 is fixedly installed at the bottom of the inner side of the alignment slide plate 26. When the connector body 1 is displaced, it enters the limiting sleeve 11 through the alignment slide plate 26, which drives the second rack 25 to pass through the bottom of the first gear 13, thereby driving the protective cover plate 15 to flip.

[0041] like Figure 9 A second gear 34 is rotatably mounted at the rear center of the connector body 1. A support rod 33 is fixedly mounted at the rear center of the second gear 34. An extension bracket 28 is symmetrically fixedly mounted at the rear of the connector body 1. A first protective partition 30 is fixedly mounted between the two extension brackets 28. A first magnetic suction plate 29 is fixedly mounted at the top of the first protective partition 30 and at the rear of the connector body 1. A second protective partition 31 is fixedly mounted at the bottom of the rear of the connector body 1. The first protective partition 30 can be flipped to a vertical or horizontal state, so that the first protective partition 30 can flexibly switch working states to protect the second gear 34 or allow the user to operate the support rod 33.

[0042] The alignment sleeve 10 is slidably fitted onto the mating insert plate 27. The contact piece 18 is connected to the end of the limiting spring 12 near the limiting sleeve 11. The movable rod 19 is slidably inserted into the support base 9, and the movable rod 19 is located in the inner ring of the limiting spring 12. The first rack 22 meshes with the second gear 34. The mating insert plate 27 is fixedly installed on the outer ring of the connector body 1. A round hole is opened inside the limiting sleeve 11. The bottom end of the first gear 13 is flush with the surface of the second rack 25. A groove is opened inside the alignment slide plate 26 near the second rack 25, and the second rack 25 is installed inside the groove. An insertion point is opened at the top of the alignment slide plate 26. The hole, the side end of the alignment slide plate 26 is inclined at 45°, the bottom end of the positioning rod 20 is in an arc state, the outer surface of the mating plate 27 is in contact with the inner wall of the alignment groove 7, the outer ring surface of the first protective partition 30 and the second gear 34, and the first protective partition 30 and the second gear 34 are spaced 1 cm apart, the inner wall of the protective cover plate 15 is inclined at 30°, and the protective cover plate 15 is located above the limiting sleeve 11, the support base 9 has an openable hole, the mating plate 27 is horizontally aligned with the plastic washer 8, the bottom end of the limiting sleeve 11 has an open slot, and the top end of the alignment slide plate 26 is in contact with the top end of the slot.

[0043] In this embodiment, the connector body 1 is connected to an external device via the socket 6 and to an external cable via the socket 6. The connector body 1 can be inserted into the socket 6. At this time, the alignment slide plate 26 slides into the limiting sleeve 11, ensuring accurate alignment between the connector body 1 and the socket 6. Simultaneously, the side surface of the alignment slide plate 26 is inclined at 45°, and the bottom end of the positioning rod 20 is rounded, improving the smoothness of the alignment slide plate 26 passing through the positioning rod 20. Subsequently, when the connector body 1 moves to complete alignment with the socket 6, the insertion hole at the top of the alignment slide plate 26 is vertically aligned with the positioning rod 20. The elasticity of the limiting spring 12 causes the positioning rod 20 to move downwards towards the alignment slide plate 26. Inside plate 26, the alignment slide 26 can be restricted to the top of the alignment sleeve 10. When the alignment slide 26 is inserted into the limiting sleeve 11, it can move the second rack 25 to engage with the first gear 13. Thus, during the insertion of the connector body 1 into the socket 6, the second rack 25 can drive the protective cover 15 to flip via the first gear 13 until the connector body 1 and socket 6 are fully aligned. At this point, the first gear 13 can drive the protective cover 15 to flip onto the outer surface of the movable rod 19, thereby protecting the movable rod 19 and the limiting spring 12 from direct contact between external objects and the movable rod 19 and the limiting spring 12. Furthermore, when the connector body 1 and socket 6 are aligned, the insert plate 27 can... The connector is moved into the alignment slot 7 until the mating plate 27 and the plastic gasket 8 are firmly attached, thus forming a secondary protection on the outer surface of the sealing ring 2 to prevent external water from entering the joint between the connector body 1 and the socket 6. When the connector body 1 needs to be disassembled from the inside of the socket 6, the first protective partition 30 can be flipped upwards until the first magnetic piece 29 on the first protective partition 30 contacts the first magnetic piece 29 at the top rear end of the connector body 1, which can support the first protective partition 30 to be placed vertically. Then, the support rod 33 can be rotated to drive the second gear 34 to rotate. Through the meshing of the two first racks 22 with the second gear 34, when the second gear 34 rotates, it can drive the two first racks 22 to move up and down respectively. The irregular bracket 23, through the reinforcing bracket 24 and the connecting crossbar 21, can move the positioning rod 20 away from the limiting sleeve 11, allowing the positioning rod 20 to be moved out from the inside of the alignment slide plate 26, thereby unlocking the connector body 1. At this time, the connector body 1 can be pulled away from the socket 6, thus removing the connector body 1 from the inside of the socket 6. Simultaneously, as the connector body 1 moves, the second rack 25 moves and resets at the bottom end of the first gear 13, causing the first gear 13 to rotate in the opposite direction, allowing the protective cover 15 to flip outwards and reset, completing the reset of the protective cover 15. Afterwards, once the connector body 1 is removed from the inside of the socket 6, the support rod 33 can be released.The elasticity of the limiting spring 12 causes the positioning rod 20 to move closer to the limiting sleeve 11, allowing the positioning rod 20 to reset the first rack 22 via the connecting crossbar 21 and the reinforcing bracket 24. This, in turn, causes the second gear 34 to rotate and reset. Subsequently, after the second gear 34 resets, the first protective partition 30 can be flipped downwards to contact and adhere to the second protective partition 31. A second magnetic suction piece 32 is installed at the bottom of the first protective partition 30 and the opposite end of the second protective partition 31, facilitating the merging and adsorption of the second protective partition 31 and the first protective partition 30, thus protecting the second gear 34. During use, when assembling the device by connecting the connector body 1 and the socket 6, the alignment slide plate 26 can be inserted. The interior of the limiting sleeve 11 allows for accurate assembly of the connector body 1 with the socket 6. Simultaneously, as the alignment slide plate 26 shifts, the second rack 25, via the first gear 13, drives the protective cover 15 to flip upwards, allowing it to enter its working state and protect the movable rod 19 and the limiting spring 12. Furthermore, the elasticity of the limiting spring 12 causes the positioning rod 20 to insert into the alignment slide plate 26, confining it within the limiting sleeve 11. This completes the assembly of the connector body 1 and the socket 6. Moreover, the sliding of the movable rod 19 within the support frame 9 allows the positioning rod 20 to slide linearly, improving the accuracy of the docking between the positioning rod 20 and the alignment slide plate 26, thus completing the process.
