Abstract
Description
Technical Field
[0001] This invention relates to a connector, and more particularly to a magnetic waterproof connection device. Prior Technology
[0002] Existing waterproof magnetic connectors are typically designed with a circular washer shape, requiring significant magnetic force and radial pressure from the washer to achieve a waterproof effect. However, because the magnetic force needs to be increased by increasing the magnetic area, such as by using a magnet, this results in a large contact area and a large volume and space required for the connector.
[0003] In view of this, the inventor, in order to improve and solve the above-mentioned deficiencies, has devoted himself to research and applied theoretical knowledge, and finally proposed an invention with a reasonable design that effectively improves the above-mentioned deficiencies. Summary of the Invention
[0004] The main objective of this invention is to provide a magnetic waterproof connection device, which adds two spaced-apart sealing rings to the waterproof gasket. These rings have different outer diameters and a tapering design, so that they can make oblique contact and interference with the inner wall of the connector. This allows excess air between the connectors to be easily squeezed out, effectively reducing the pressure of the gaskets, achieving easier connection and waterproofing. Furthermore, the reduced magnetic attraction area decreases the magnetic adsorption area, which also reduces the size of the connector.
[0005] To achieve the above objectives, the present invention provides a magnetic waterproof connection device, comprising a first connector and a second connector; the first connector has a first connecting body, a first insertion portion protruding from the first connecting body, and a first terminal block disposed in the first insertion portion, the first insertion portion having a socket end, the first terminal block being disposed within the first insertion portion corresponding to the socket end, and the first terminal block having at least one first terminal and at least one first magnetic element; the second connector has a second connecting body, a second insertion portion protruding from the second connecting body, and a second insertion portion. The first connector includes a connector portion and a second terminal block disposed on the second connector portion. The second connector portion corresponds to the socket end, and the second terminal block is disposed inside the second connector portion. The second terminal block is provided with at least one second terminal and at least one second magnetic attraction element. The second connector portion is provided with an annular sealing structure. The annular sealing structure has a sealing body and a first sealing ring and a second sealing ring arranged in a ring at intervals outside the sealing body. The inner wall of the socket end of the first connector portion is inclined. When the first connector and the second connector are mated, the first sealing ring and the second sealing ring abut against the inner wall of the socket end. Simple Explanation of the Diagram

[0012] To enable your review committee to further understand the features and technical content of this invention, please refer to the following detailed description and drawings of this invention. However, the drawings are provided for reference and illustration only and are not intended to limit this invention.
[0013] Please refer to Figures 1 and 2, which are perspective views of the present invention in a separated state and a perspective view of it in a mated state, respectively. The present invention provides a magnetic waterproof connection device, comprising a first connector 1 and a second connector 2; wherein:
[0014] Please refer to Figure 3. The first connector 1 has a first connecting body 10, a first plug-in portion 11 protruding from the first connecting body 10, and a first terminal block 12 disposed on the first plug-in portion 11. The first connecting body 10 may have a first buffer end 100 and be connected to a first cable 101, while the first plug-in portion 11 may be disposed on one surface of the first connecting body 10, so that the plugging direction of the first connector 1 and the second connector 2 is perpendicular to the first cable 101. The first plug-in portion 11 has a socket end 110, so that the first terminal block 12 is disposed in the first plug-in portion 11 corresponding to the socket end 110. The first terminal block 12 is provided with at least one first terminal 120 and a first magnetic attraction element 121; in the embodiment of the present invention, the first magnetic attraction element 121 is in a ring shape surrounding the first terminal 120.
[0015] As described above, the second connector 2 has a second connecting body 20, a second plug-in portion 21 protruding from the second connecting body 20, and a second terminal block 22 disposed on the second plug-in portion 21. The second connecting body 20 may have a second buffer end 200 and be connected to a second cable 201, while the second plug-in portion 21 may be disposed on one surface of the second connecting body 20, so that the insertion direction of the second connector 2 and the first connector 1 is perpendicular to the second cable 201. The second plug-in portion 21 corresponds to the socket end 110 of the first connector 1 and at least allows the front end 210 of the second plug-in portion 21 to be inserted into the socket end 110, and the second terminal block 22 is disposed in the second plug-in portion 21, and the second terminal block 22 is provided with at least one second terminal 220 and a second magnetic attraction element 221; in the embodiment of the present invention, the second magnetic attraction element 221 is annular and surrounds the second terminal 220. Accordingly, as shown in Figure 4, when the first connector 1 and the second connector 2 are plugged in, the second plug-in part 21 is inserted into the plug end 110 of the first connector 1, so that the first terminal 120 and the second terminal 220 are plugged in to achieve electrical connection. At the same time, the first magnetic element 121 and the second magnetic element 221 can also attract each other because the first terminal base 12 and the second terminal base 22 are close to each other, thereby preventing the first connector 1 and the second connector 2 from being easily separated.
[0016] Please refer to Figures 3 and 3A. The main feature of this invention is that an annular sealing structure 23 is provided outside the second insertion portion 21. The annular sealing structure 23 has a sealing body 230 and a first sealing ring 231 and a second sealing ring 232 arranged in a spaced ring outside the sealing body 230. The outer diameter d of the first sealing ring 231 is smaller than the outer diameter D of the second sealing ring 232, and the first sealing ring 231 is closer to the end face of the second insertion portion 21 than the second sealing ring 232. In the embodiment of the present invention, the second insertion part 21 is provided with a laterally recessed annular groove 211, and the sealing body 230 is embedded in the annular groove 211 so that the first sealing ring 231 and the second sealing ring 232 extend out laterally; specifically, the annular groove 211 may also have a first fitting surface 211a and a second fitting surface 211b, the first fitting surface 211a and the second fitting surface 211b are respectively inclined and connected at the high point of their inclination to increase the tightness when fitted with the sealing body 230. Furthermore, as shown in Figure 3A, the sealing body 230 may have a first annular surface 230a and a second annular surface 230b on the outside, and the first sealing ring 231 and the second sealing ring 232 are respectively disposed on them. The first annular surface 230a may be inclined so that an extension line C of the first sealing ring 231 forms an angle α with a horizontal line L, thereby increasing the distance between it and the second sealing ring 232, so as to reduce the squeezing force of the first sealing ring 231 when it is mated.
[0017] As shown in Figures 4 and 4A, the inner wall of the socket end 110 of the first plug-in portion 11 may be inclined. Specifically, the socket end 110 may have a first inner wall 110a and a second inner wall 110b sequentially from the inside to the outside, and there is an inclined inner wall 110c between the first inner wall 110a and the second inner wall 110b, so that when the first connector 1 and the second connector 2 are mated, the first sealing ring 231 and the second sealing ring 232 of the above-mentioned annular sealing structure 23 can abut against the inclined inner wall 110c to achieve a sealing or waterproof effect.
[0018] Therefore, the magnetic waterproof connection device of the present invention can be obtained by means of the above-described structure.
[0019] Therefore, the magnetic waterproof connection device of the present invention has a first sealing ring 231 and a second sealing ring 232 spaced apart, with different outer diameters and a tapering design, so as to make oblique contact and interference with the inner wall of the first connector 1. In this way, excess air between the first connector 1 and the second connector 2 can be easily squeezed out, and the pressure force of the annular sealing structure 23 can be effectively reduced, so as to achieve easy docking and waterproof effect. In addition, due to the reduction of attraction force, the magnetic adsorption area is reduced, and the volume of the first connector 1 and the second connector 2 can be reduced.
[0020] In conclusion, this invention can indeed achieve the intended use described in the above specification and solve the deficiencies of the prior art. Furthermore, due to its novelty and progressiveness, it fully meets the requirements for an invention patent application. Therefore, this application is filed in accordance with the Patent Act.
