Description

Technical Field

[0001] The utility model relates to the technical field of water-cooled ozone generators, in particular to a high-voltage connection device for water-cooled ozone generators. Background Art

[0002] The working principle of an ozone generator is to use high-voltage electricity to decompose oxygen into oxygen ions and free electrons through electric field discharge. Under specific conditions, these oxygen ions and free electrons combine with oxygen atoms under the action of the electric field to form ozone molecules. A water-cooled ozone generator refers to an ozone generator with a water-cooling circulation system. Since an ozone generator generates a large amount of heat during operation, water cooling is required to cool the device in a timely manner.

[0003] The high-voltage connection device is used to connect a high-voltage power supply to a water-cooled ozone generator. Existing high-voltage connection devices generally use screws to lock the wire, which is prone to incomplete locking, resulting in loose connection at the joint and easy detachment. At the same time, the existing high-voltage connection device has poor sealing performance and is prone to internal water ingress in a humid environment. Summary of the Utility Model

[0004] The utility model provides a high-voltage connection device for a water-cooled ozone generator, which is provided with a wire fixing structure, an outgoing line sealing structure and a joint sealing structure to solve the problems existing in the above-mentioned prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The high-voltage connection device for a water-cooled ozone generator includes a plug and a socket. Both the plug and the socket include a cylinder body. A plurality of wiring holes are opened in the cylinder body. A wire fixing structure for locking the wire is arranged in the wiring hole. Outgoing line sealing structures are arranged at one ends of the two cylinder bodies away from each other. A plurality of male connectors are fixed at one end of the cylinder body of the plug close to the socket. The male connectors are connected to the wires in the corresponding wiring holes of the plug. A plurality of female connectors are fixed at one end of the cylinder body of the socket close to the plug. The female connectors are connected to the wires in the corresponding wiring holes of the socket. The male connectors and the female connectors are in plug-in fit. A joint sealing structure is arranged at the docking part of the plug and the socket. By setting the outgoing line sealing structure and the joint sealing structure, sufficient sealing protection for the plug and the socket can be formed to avoid water ingress through the gap and resulting in electric leakage.

[0007] Furthermore, the wire fixing structure includes a first toothed strip and a second toothed strip arranged in the wiring hole. A pressing block is slidably installed on the inner wall of the wiring hole. The pressing block is used to press the second toothed strip towards the first toothed strip, so that the second toothed strip cooperates with the first toothed strip to clamp the wire.

[0008] Furthermore, a first inclined surface is arranged at one end of the pressing block away from the outgoing line sealing structure. A second inclined surface cooperating with the pressing block is opened on the second toothed strip.

[0009] Furthermore, the male connector is fixedly connected to the first and second toothed bars inside the plug, and both are made of metal. The female connector is fixedly connected to the first and second toothed bars inside the socket, and both are made of metal.

[0010] Furthermore, the wire outlet sealing structure includes an annular sleeve threadedly engaged with the cylinder body. A pressure plate is sleeved inside the annular sleeve. Multiple wire outlet holes are provided on the pressure plate. A first sealing gasket is provided at the intersection of the annular sleeve and the pressure plate. A sealing member is provided on one side of the annular sleeve close to the cylinder body. A tapered wire outlet portion is provided on the sealing member.

[0011] Furthermore, the wire outlet holes are flared, and the tapered wire outlet portion cooperates with the wire outlet holes to clamp the wire passing through the tapered wire outlet portion.

A convex edge is provided on the part of the cylinder of the plug close to the socket. A second sealing gasket is provided between the convex edge and the cylinder body. A locking sleeve is sleeved on the cylinder body. The locking sleeve is threadedly engaged with the convex edge and presses the cylinder body and the convex edge against the second sealing gasket.

[0013] Furthermore, the male and female connectors are in interference fit.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By providing the plug and the socket, and opening wiring holes in the cylinders of the plug and the socket, and providing a wire fixing structure, the first and second toothed bars can cooperate to firmly bite the wire, preventing the wire from falling off; by providing structures such as the annular sleeve, the sealing member, and the pressure plate, the annular sleeve can clamp the sealing member and the pressure plate, making the seal between the annular sleeve and the cylinder body, and at the same time making the first sealing gasket and the tapered wire outlet portion seal the gaps between the annular sleeve and the pressure plate, and between the wire and the wire outlet holes respectively, realizing the sealing of the wire outlet ends of the plug and the socket.

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] As Figures 1 to 6 shown, the high-voltage connection device of the water-cooled ozone generator provided in Embodiment 1 of the present utility model includes a plug 1 and a socket 2. The plug 1 and the socket 2 are respectively connected to the high-voltage power supply and the wires of the water-cooled ozone generator. The plug 1 and the socket 2 can be docked to achieve the connection of the power supply and the electrical appliance. Specifically, as Figure 1 shown, both the plug 1 and the socket 2 include a cylinder 3, and three wiring holes 4 are opened in each of the two cylinders 3. The three wiring holes 4 are all parallel to the axis of the cylinder 3. A wire fixing structure for fixing the wire is provided in the wiring hole 4.

[0027] Combined with Figures 2 to 4 , it can be seen that three male heads 5 are fixed at one end of the cylinder 3 of the plug 1, and each male head 5 is respectively connected to the wire fixing structure in the wiring hole 4. Similarly, three female heads 6 are fixed at one end of the cylinder 3 of the socket 2, and the three female heads 6 are respectively connected to the wire fixing structures in the corresponding wiring holes 4. The male head 5 and the female head 6 can be inserted with an interference fit, so as to complete the connection between the wire of the high-voltage power supply and the wire of the water-cooled ozone generator.

[0028] As Figure 2As shown in the figure, the wire fixing structure of the present utility model includes a first toothed strip 7 and a second toothed strip 8. Among them, the first toothed strip 7 is fixed in the wiring hole 4, while the second toothed strip 8 has a certain movement space. The metal part of the wire can be inserted between the first toothed strip 7 and the second toothed strip 8, and then a pressing block 9 slidably mounted on the inner wall of the wiring hole 4 is used to cooperate with the second toothed strip 8, so that the second toothed strip 8 can cooperate with the first toothed strip 7 to clamp the wire. Since both the first toothed strip 7 and the second toothed strip 8 are multi-toothed structures and the teeth are staggered, the wire can be bitten to prevent the wire from falling off.

[0029] As Figure 2 shown, in order to make it easier for the pressing block 9 to push the second toothed strip 8 to move towards the first toothed strip 7, a first inclined surface 10 is provided at one end of the pressing block 9 close to the male head 5 or the female head 6, and a second inclined surface 11 is provided on the second toothed strip 8. When the pressing block 9 moves into the wiring hole 4, the first inclined surface 10 can press the second inclined surface 11, causing the second toothed strip 8 to move towards the first toothed strip 7, thereby clamping the wire.

[0030] At the same time, in order to strengthen the connection between the wire and the male head 5 or the female head 6, as Figure 2 shown, one end of the first toothed strip 7 and the second toothed strip 8 in the plug 1 is fixedly connected to the corresponding male head 5, and the first toothed strip 7 and the second toothed strip 8 in the socket 2 are both fixedly connected to the corresponding female head 6. The male head 5, the female head 6, the first toothed strip 7 and the second toothed strip 8 are all made of metal and can conduct electricity, while the column 3 and the pressing block 9 are both made of insulating materials.

[0031] Through the above settings, inserting the pressing block 9 into the wiring hole 4 can make the second toothed strip 8 cooperate with the first toothed strip 7 to clamp the wire and prevent the wire from falling off.

[0032] Outlet sealing structures are provided at both ends of the two columns 3 that are away from each other, and a joint sealing structure is provided at the docking part of the plug 1 and the socket 2.

[0033] Embodiment 2

[0034] On the basis of Embodiment 1, in order to increase the sealing performance and prevent water from entering the high-voltage connection device, the present utility model proposes that the outlet sealing structure is provided at the end of the column 3 away from the male head 5 or the female head 6 in Embodiment 2. Specifically, as Figure 2 and Figure 5 shown, the outlet sealing structure of the present utility model includes an annular sleeve 12, a pressure plate 13 and a sealing member 16. Among them, the annular sleeve 12 is in threaded cooperation with the column 3, and the pressure plate 13 is sleeved inside the annular sleeve 12. When the annular sleeve 12 moves towards the column 3, the annular sleeve 12 can abut against the pressure plate 13 and press the pressure plate 13 towards the column 3. And in order to be able to lead out the wire, three wire outlet holes 14 are correspondingly provided on the pressure plate 13. The wire outlet holes 14 are in a horn shape, and the diameter of the end of the wire outlet hole 14 close to the column 3 is larger.

[0035] As Figure 2 shown, a first gasket 15 is provided at the intersection of the edges of the annular sleeve 12 and the pressure plate 13, and the seal 16 is provided between the annular sleeve 12 and the cylinder 3, and a tapered wire outlet portion 17 cooperating with the wire outlet hole 14 is provided on the seal 16. The tapered wire outlet portion 17 and the seal 16 are of an integrally formed structure and are both made of an elastic insulating material. When the annular sleeve 12 is locked to the cylinder 3, the annular sleeve 12 presses the first gasket 15 and the pressure plate 13, and further presses the seal 16 and the tapered wire outlet portion 17, so that the tapered wire outlet portion 17 clamps the wire passing through the tapered wire outlet portion 17 in cooperation with the wire outlet hole 14, sealing the gap between the wire outlet hole 14 and the wire, and the first gasket 15 can seal the gap between the annular sleeve 12 and the pressure plate 13. The seal 16 can seal the gap between the annular sleeve 12 and the cylinder 3, thereby forming a seal for one end of the cylinder 3 away from the male head 5 or the female head 6, preventing water from entering from the wire outlet.

[0036] Embodiment 3

[0037] Based on Embodiments 1 and 2, the present utility model further proposes Embodiment 3 to seal the docking portion of the male head 5 and the female head 6. Specifically, as Figure 2 shown, the joint sealing structure of this embodiment includes a cylinder body 18 fixed to one end of the cylinder 3 of the socket 2 away from the annular sleeve 12, and a convex edge 19 is fixed to one end of the cylinder 3 of the plug 1 away from the annular sleeve 12. A second gasket 20 is sleeved on the convex edge 19. When the convex edge 19 and the cylinder 3 clamp the second gasket 20, a seal for the male head 5 and the female head 6 can be formed.

[0038] Specifically, a locking sleeve 21 is sleeved on the cylinder body 18. One end of the locking sleeve 21 can abut against the cylinder body 18, and the other end of the locking sleeve 21 is in threaded cooperation with the convex edge 19. In this way, when the locking sleeve 21 is rotated, the locking sleeve 21 can drive the convex edge 19 and the cylinder body 18 to approach each other, thereby squeezing the second gasket 20 to seal the gap between the cylinder body 18 and the convex edge 19, preventing water from entering the docking portion of the male head 5 and the female head 6.
