[0002] Electrical connectors are a crucial basic component in electronic engineering. Their core function is to establish separable electrical signal or power transmission paths between two independent circuits or devices.

[0003] In the existing technology, when users use electrical connectors, if they perform plugging and unplugging operations, it is easy to cause hand slippage, resulting in inconvenience in operation.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN210468146U) discloses a direct-insertion circular electrical connector, including a plug housing, a socket housing, a protective shell, a disassembly structure, and pins. The socket housing has a protective shell installed at one end, and a splicing groove is provided at the end of the socket housing away from the protective shell. A plug housing is provided on one side of the splicing groove, and a splicing component is fixed to the end of the plug housing near the protective shell. One end of the splicing component extends into the interior of the splicing groove. Snap-fit ​​grooves are provided on the outer walls of both sides of the splicing component, and a disassembly structure is provided on the inner wall of the splicing groove at the snap-fit ​​groove location. A connecting block is fixed to the end of the plug housing away from the splicing component, and a fixing cover is provided on the outer side of the pins. This not only improves the convenience of disassembling and assembling the circular electrical connector and enhances the stability of the pins during insertion and removal, but also reduces the possibility of slippage when plugging and unplugging the circular electrical connector.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation. For example, when electrical connectors are used in humid environments, humid air can easily penetrate the connection points of the electrical connectors, which can easily lead to internal moisture short circuits and affect the safe use of the electrical connectors. Utility Model Content

[0006] The purpose of this invention is to provide a waterproof electrical connector with a self-locking mechanism to solve the problem mentioned in the background art that when the electrical connector is used in a humid environment, humid air can easily penetrate the connection position of the electrical connector, which can easily lead to internal moisture short circuits and affect the safe use of the electrical connector.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a waterproof electrical connector with a self-locking mechanism, comprising a first connecting end and a second connecting end connected to the inner side of the first connecting end; a first sealing air cushion is provided at the end of the first connecting end, and a waterproof component is installed at the rear end of the first sealing air cushion; a positioning chamber is installed on the outer side of the second connecting end, and a self-locking mechanism is provided inside the positioning chamber.

[0008] Furthermore, the waterproof component is provided with a second sealing gasket, and the outer side of the second sealing gasket is fixedly installed on the inner wall of the first connecting end.

[0009] Furthermore, the second sealing gasket is connected to the first sealing gasket through an air guide tube, and the first sealing gasket and the second connecting end form a pressing structure. Both the second sealing gasket and the first sealing gasket are annularly arranged, and the connection points of the second sealing gasket with the first connecting end and the second connecting end correspond.

[0010] Furthermore, the self-locking mechanism is provided with a positioning block, and the inner side of the positioning block is fixedly installed on the surface of the first connecting end. The positioning block is L-shaped, and a slot is provided on the surface of the positioning block.

[0011] Furthermore, an auxiliary pull plate is installed through the interior of the positioning chamber, and a locking block is fixedly installed on the inner side of the auxiliary pull plate. The locking block is correspondingly set with the slot, and both the slot and the locking block are inclined. A pressure spring is sleeved in the middle of the auxiliary pull plate, and the upper and lower ends of the pressure spring are installed between the positioning chamber and the locking block.

[0012] Furthermore, an air supply airbag is fixedly installed inside the positioning chamber, and the air supply airbag and the positioning block form a compression structure.

[0013] Furthermore, the second connecting end is provided with a support airbag inside, and a locking arc block is installed on the outside of the support airbag. The upper end of the locking arc block corresponds to the inner wall of the first connecting end, and the support airbag and the air supply airbag are connected through an air supply pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, the first connecting end is mated with the second connecting end. After mating, the surface of the second connecting end presses against the first sealing gasket at the end of the first connecting end. The first sealing gasket is compressed and the air inside is delivered to the second sealing gasket through the air guide tube. The second sealing gasket expands after receiving the gas, forming a ring seal at the mating point of the first and second connecting ends, improving the sealing effect and further ensuring the waterproofness of the electrical connector.

[0015] 2. When the first connecting end and the second connecting end are connected, the positioning block on the outside of the first connecting end is inserted along the second connecting end. After being inserted, the positioning block presses the locking block inside the positioning chamber. Due to the inclined shape of the locking block itself, the locking block is inserted into the slot under the action of the pressure spring, which locks the positioning block and the first connecting end, thereby achieving the effect of automatic locking. No additional steps are required, and the operation is simple and convenient. Furthermore, when the positioning block is embedded inside the positioning chamber, the positioning block compresses the air supply bladder. The compressed air supply bladder delivers the internal air to the support bladder through the air supply pipe. After receiving the air, the support bladder expands. The expanded support bladder pushes the locking arc block outward, so that the locking arc block fits tightly against the inner wall of the first connecting end, achieving a secondary locking effect, which can further improve the stability of the locking.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 5The technical solution shown is a waterproof electrical connector with a self-locking mechanism. To solve the problem of poor waterproofing, it discloses: a first connecting end 1 and a second connecting end 2 connected to the inner side of the first connecting end 1; a first sealing gasket 3 is provided at the end of the first connecting end 1, and a waterproof component is installed at the rear end of the first sealing gasket 3. The waterproof component is provided with a second sealing gasket 5, and the outer side of the second sealing gasket 5 is fixedly installed on the inner wall of the first connecting end 1. The second sealing gasket 5 and the first sealing gasket 3 are connected by an air guide tube 4, and the first sealing gasket 3 and the second connecting end 2 form a pressing structure. Both the second sealing gasket 5 and the first sealing gasket 3 are annularly arranged, and the connection point of the second sealing gasket 5 corresponds to that of the first connecting end 1 and the second connecting end 2.

[0025] In use, the first connecting end 1 is mated with the second connecting end 2. After mating, the surface of the second connecting end 2 presses against the first sealing gas pad 3 at the end of the first connecting end 1. The first sealing gas pad 3 is compressed and the internal air is transported to the second sealing gas pad 5 through the air guide tube 4. The second sealing gas pad 5 expands after receiving the gas, forming a ring seal at the mating point of the first connecting end 1 and the second connecting end 2, improving the sealing effect and further ensuring the waterproofness of the electrical connector.

[0026] Example 2: Figures 1-6 The technical solution shown, based on Embodiment 1, discloses the following to address the inconvenience of locking and unlocking: a positioning chamber 8 is installed on the outer side of the second connecting end 2, and a self-locking mechanism is provided inside the positioning chamber 8. The self-locking mechanism includes a positioning block 6, and the inner side of the positioning block 6 is fixedly installed on the surface of the first connecting end 1. The positioning block 6 is L-shaped, and a slot 7 is provided on the surface of the positioning block 6. An auxiliary pull plate 9 is installed through the interior of the positioning chamber 8, and a locking block 10 is fixedly installed on the inner side of the auxiliary pull plate 9, with the locking block 10 corresponding to the slot 7. The design includes a slot 7 and a locking block 10, both of which are inclined. A pressure spring 11 is fitted in the middle of the auxiliary pull plate 9, and the upper and lower ends of the pressure spring 11 are installed between the positioning chamber 8 and the locking block 10. An air supply airbag 12 is fixedly installed inside the positioning chamber 8, and the air supply airbag 12 and the positioning block 6 form a pressing structure. A support airbag 14 is provided inside the second connecting end 2, and a locking arc block 15 is installed on the outside of the support airbag 14. The upper end of the locking arc block 15 corresponds to the inner wall of the first connecting end 1, and the support airbag 14 and the air supply airbag 12 are connected through an air supply pipe 13.

[0027] When the first connecting end 1 mates with the second connecting end 2, the positioning block 6 on the outer side of the first connecting end 1 embeds itself along the second connecting end 2. The embedded positioning block 6 presses against the locking block 10 inside the positioning chamber 8. Due to the inclined shape of the locking block 10, it pushes the auxiliary pull plate 9 outwards when pressed until the locking block 10 aligns with the slot 7. Then, under the action of the pressure spring 11, the locking block 10 embeds itself into the slot 7, engaging the positioning block 6 with the first connecting end 1, thus achieving an automatic locking effect. Conversely, pulling the auxiliary pull plate 9 can... The first connecting end 1 can be removed and automatically locked without any additional steps, making the operation simple and convenient. At the same time, when the positioning block 6 is embedded inside the positioning chamber 8, the positioning block 6 compresses the air supply bladder 12. The compressed air supply bladder 12 delivers the internal air to the support bladder 14 through the air supply pipe 13. After receiving the air, the support bladder 14 expands. The expanded support bladder 14 pushes the locking arc block 15 outward, so that the locking arc block 15 fits tightly against the inner wall of the first connecting end 1, achieving a secondary locking effect and further improving the stability of the locking.
