Description
Technical Field
[0001] This invention relates to the field of electronic component technology, specifically a waterproof electronic connector. Background Technology
[0002] An electronic connector is a conductive device that bridges two conductors in a circuit, allowing current or signals to flow from one conductor to the other. It is widely used in various electrical circuits to connect or disconnect current or signals. This connection can be temporary and easily plugged in and out, or it can be a permanent junction between electrical devices or wires. Electronic connectors are devices for transmitting electronic signals (analog or digital signals), providing a separate interface for connecting two secondary electronic systems; they are components used to complete electrical connections between circuits or electronic devices.
[0003] With increasingly stringent waterproof and dustproof requirements for communication equipment, external interfaces of these devices must ensure structural reliability while meeting high levels of waterproof and dustproof standards. Current methods for waterproofing electronic connectors involve injecting waterproof adhesive into the gaps at the connection points or using sealing gaskets; however, waterproof adhesives tend to crack over time, and sealing gaskets cannot completely seal the gaps, resulting in relatively poor waterproof performance. Summary of the Invention
[0004] The purpose of this invention is to provide a waterproof electronic connector to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A waterproof electronic connector includes a socket body and a plug part. A wire runs through the middle of the socket body, with an electrical contact at its front end. The plug part has a insertion groove in its center, and the front end of the wire is inserted into the insertion groove. The insertion groove contains an electrical contact groove that mates with the electrical contact. A pressure platform is provided at the rear of the socket body, and a step and a drainage groove are provided on the outer wall of the socket body. When the front end of the socket body is inserted into the insertion groove, the pressure platform fits against the front face of the plug part, and multiple grooves are provided on the outer wall of the pressure platform. The drain hole is connected to the drain groove. The stepped part and the inner wall of the plug-in cylinder groove are threaded together, and the drain groove is located on the side of the stepped part near the pressure table. The plug part is also provided with an annular cavity, and the end of the annular cavity near the socket body is provided with a storage port that can be connected to the drain groove. An air bladder is installed at the storage port. The annular cavity is provided with a pressure regulating component for adjusting the air pressure inside the annular cavity. When the air bladder is inflated, it can extend into the air bladder and seal the connection between the outer wall of the socket body and the inner wall of the plug-in cylinder groove.
[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions:
[0008] In one alternative: the radial depth of the drainage channel gradually increases from the stepped section to the pressure plate.
[0009] In one alternative embodiment: the annular cavity is further provided with a plurality of first springs, one end of which is connected to the inner wall of the annular cavity and the other end is connected to the airbag component; the first springs are always in a stretched state.
[0010] In one alternative embodiment: the pressure regulating assembly includes a piston ring, a connecting rod, a magnetic ring, an electromagnetic block, and a pressure-boosting spring. The piston ring and the magnetic ring are both slidably disposed inside the annular chamber. The piston ring and the magnetic ring are fixedly connected by the connecting rod. The end face of the piston ring away from the magnetic ring is connected to the end wall of the annular chamber by the pressure-boosting spring. The electromagnetic block is disposed on the end face of the plug portion away from the socket body, and the electromagnetic block generates a magnetic attraction force with the magnetic ring after being energized.
[0011] In one alternative embodiment: the end of the socket body extending into the plug-in slot is further provided with a protruding ring portion, and an annular groove is formed between the protruding ring portion and the stepped portion. A connecting hole is provided on the side wall of the annular chamber. When the socket body is inserted into the plug-in slot, the connecting hole corresponds to the annular groove. A limiting component is provided inside the connecting hole, and one end of the limiting component can extend into the plug-in slot, while the other end is slidably connected to the connecting rod. When the connecting rod moves away from the electromagnetic block, the limiting component can move into the plug-in slot and extend into the annular groove. When the connecting rod moves towards the electromagnetic block, the limiting component moves radially outward from the plug portion and the end of the limiting component disengages from the annular groove.
[0012] In one alternative embodiment: the limiting component includes a limiting strip, a wedge, and a limiting head. The limiting strip passes through a connecting hole, and the wedge is located on one end face of the limiting strip. The inclined surface of the wedge abuts against the side of the connecting hole. The limiting strip is provided with a connecting through hole, and a connecting rod passes through the connecting through hole. The limiting strip can move radially relative to the connecting rod. The end of the limiting strip that extends into the insertion slot has a limiting head.
[0013] In one alternative: the inner wall of the connecting through hole has a guide groove, the side of the connecting rod is provided with a protrusion that slides inside the guide groove, and the end face of the connecting rod is connected to the end wall of the limiting strip by a second spring.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] 1. In this invention, water stains on the outside of the socket body and the plug may enter the drain groove through the part of the plug that contacts the pressure table at the front end. Most of the water stains flow out through the drain hole, which can reduce the amount of water stains entering the plug groove.
[0016] 2. In this invention, the pressure regulating component is used to increase the air pressure inside the annular chamber. The increase in air pressure in the annular chamber can cause the airbag to extend into the drainage groove and bulge, thereby sealing the gap between the step and the inner wall of the plug-in groove, effectively increasing the sealing between the socket body and the plug-in groove, and further improving the waterproof effect.
[0017] 3. The present invention has a simple structure and is easy to install. It drains water stains in time through drainage grooves and drainage holes, and seals the gap between the step part and the inner wall of the plug-in cylinder groove through the airbag component, which greatly improves the waterproof performance, ensures the safety of electrical connection, and has strong practicality.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.
[0024] In one embodiment, such as Figures 1-3As shown, a waterproof electronic connector includes a socket body 100 and a plug portion 200. A wire 110 is disposed in the middle of the socket body 100, passing through both ends. The front end of the wire 110 has an electrical contact. The plug portion 200 has a insertion groove 210 in its center, and the front end of the wire 110 is inserted into the insertion groove 210. The insertion groove 210 has an electrical contact groove 211 that mates with the electrical contact. A pressure plate 120 is disposed at the rear of the socket body 100, and a step portion 130 and a drainage groove 140 are disposed on the outer wall of the socket body 100. When the front end of the socket body 100 is inserted into the insertion groove 210, the pressure plate 120 is in contact with the front end face of the plug portion 200, and the outer wall of the pressure plate 120 has... Multiple drainage holes 160 are connected to the drainage groove 140. The stepped portion 130 is threadedly engaged with the inner wall of the plug-in tube groove 210, and the drainage groove 140 is located on the side of the stepped portion 130 near the pressure table 120. The plug portion 200 is also provided with an annular chamber 220, and the end of the annular chamber 220 near the socket body 100 is provided with a storage port 221 that can be connected to the drainage groove 140. An airbag component 222 is installed at the storage port 221. The annular chamber 220 is provided with a pressure regulating component for adjusting the air pressure inside the annular chamber 220. When the airbag component 222 is inflated, it can extend into the airbag component 222 and seal the connection between the outer wall of the socket body 100 and the inner wall of the plug-in tube groove 210.
[0025] In this embodiment of the invention, the front end of the socket body 100 is inserted into the plug slot 210 and is fastened by threaded engagement between the outer wall of the stepped portion 130 and the inner wall of the plug slot 210. The end face of the pressure plate 120 abuts against the front end face of the plug portion 200, and the portion of the plug portion 200 in contact with the pressure plate 120 covers the outer side of the drain groove 140. At this time, the receiving opening 221 is opposite to the drain groove 140, and the airbag 222 is recessed inside the annular chamber 220. The pressure regulating component increases the air pressure inside the annular chamber 220. The increased air pressure in the annular chamber 220 causes the airbag 222 to extend into the drain groove 140 and bulge, thereby... The airbag component 222 can seal the gap between the stepped portion 130 and the inner wall of the plug slot 210, thereby effectively increasing the sealing between the socket body 100 and the plug slot 210. Water stains on the outside of the socket body 100 and the plug portion 200 may enter the drain groove 140 through the part of the plug portion 200 that contacts the pressure plate 120. Most of the water stains flow out through the drain hole 160. At the same time, 22 can seal the gap between the stepped portion 130 and the inner wall of the plug slot 210, preventing water stains from entering the part of the contact groove 211 that contacts the electrical contact through the gap between the socket body 100 and the plug slot 210, thereby effectively improving the waterproof effect.
[0026] In one embodiment, such as Figure 2 and Figure 3As shown, the radial depth of the drainage groove 140 gradually increases from the step portion 130 to the pressure plate 120; when water stains enter the drainage groove 140 through the upper side of the socket body 100 and the plug portion 200, the water stains will first flow to the deeper part of the drainage groove 140, thereby moving away from the step portion 130, and finally being discharged through the drainage hole 160, thereby further improving the waterproof performance.
[0027] In one embodiment, such as Figure 1 and Figure 3 As shown, the annular chamber 220 is also provided with a plurality of first springs 223. One end of the first spring 223 is connected to the inner wall of the annular chamber 220 and the other end is connected to the airbag component 222. The first spring 223 is always in a stretched state. In this embodiment of the invention, when the air pressure inside the annular chamber 220 decreases, the contraction force of the first spring 223 can pull the airbag component 222 and cause the airbag component 222 to be recessed into the annular chamber 220, so as to prevent the airbag component 222 from obstructing the disassembly of the socket body 100.
[0028] In one embodiment, such as Figure 1 and Figure 3 As shown, the pressure regulating assembly includes a piston ring 230, a connecting rod 240, a magnetic ring 260, an electromagnetic block 270, and a pressure-boosting spring 290. Both the piston ring 230 and the magnetic ring 260 are slidably disposed inside the annular chamber 220. The piston ring 230 and the magnetic ring 260 are fixedly connected by the connecting rod 240. The end face of the piston ring 230 away from the magnetic ring 260 is connected to the end wall of the annular chamber 220 via the pressure-boosting spring 290. The electromagnetic block 270 is disposed on the end face of the plug portion 200 away from the socket body 100, and the electromagnetic block 270 is energized. A magnetic attraction force is generated between the electromagnetic block 270 and the magnetic ring 260. In this embodiment of the invention, when the electromagnetic block 270 is energized, the electromagnetic block 270 and the magnetic ring 260 generate a magnetic attraction force, so that the magnetic ring 260 and the piston ring 230 can overcome the elastic force of the pressure spring 290 and move toward the electromagnetic block 270. As a result, the space between the piston ring 230 and the end wall of the annular chamber 220 increases, and the internal air pressure decreases. Under the pull of the first spring 223, the airbag 222 retracts into the annular chamber 220, thereby facilitating the disassembly and installation of the socket body 100 and the plug part 200.
[0029] In one embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the end of the socket body 100 that extends into the plug-in slot 210 is also provided with a protruding ring portion 150. A ring groove is formed between the protruding ring portion 150 and the stepped portion 130. A connecting hole 280 is provided on the side wall of the annular chamber 220. When the socket body 100 is inserted into the plug-in slot 210, the connecting hole 280 corresponds to the annular groove. A limiting member 250 is provided inside the connecting hole 280, with one end extending into the plug-in slot 210 and the other end slidably connected to the connecting rod 240. When the connecting rod 240 moves away from the electromagnetic block 270, the limiting member 250 can move into the plug-in slot 210 and extend into the annular groove. When the connecting rod 240 moves towards the electromagnetic block 270, the limiting member 250 moves towards the plug portion 20. The outer side of the socket body 100 moves radially and restricts the end of the component 250 from disengaging from the annular groove. In this embodiment of the invention, after the front end of the socket body 100 is inserted into the insertion cylinder groove 210, the piston ring 230, connecting rod 240 and magnetic ring 260 move away from the electromagnetic block 270 under the action of the electromagnetic block 270, thereby restricting the component 250 from moving towards the center line of the plug part 200, and the end of the restricting component 250 extends into the annular groove, thereby effectively preventing the socket body 100 from disengaging from the plug part 200, increasing the connection strength between the socket body 100 and the plug part 200. When the connecting rod 240 moves towards the electromagnetic block 270, the restricting component 250 moves away from the center line of the plug part 200 and disengages from the annular groove, thereby not hindering the socket body 100 from being disassembled from the plug part 200.
[0030] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the limiting component 250 includes a limiting strip 251, a wedge 252, and a limiting head 253. The limiting strip 251 passes through the connecting hole 280, and the wedge 252 is disposed on one end face of the limiting strip 251. The inclined surface of the wedge 252 abuts against the side portion of the connecting hole 280. The limiting strip 251 is provided with a connecting through hole 254, and the connecting rod 240 passes through the connecting through hole 254. The limiting strip 251 can move radially relative to the connecting rod 240. The limiting strip 251 extends into the insertion slot. The end of 210 has a limiting head 253. In this embodiment of the invention, when the connecting rod 240 moves inside the annular chamber 220, the limiting strip 251 moves with the connecting rod 240. Since the inclined surface of the wedge block 252 contacts the end wall of the connecting hole 280, the limiting strip 251 can move radially. When the lower end of the limiting strip 251 extends into the annular groove, the limiting head 253 can abut against the protruding ring portion 150, thereby preventing the socket body 100 from disengaging from the plug portion 200.
[0031] In one embodiment, such as Figure 4As shown, the inner wall of the connecting through hole 254 has a guide groove 255, and the side of the connecting rod 240 is provided with a protrusion that slides inside the guide groove 255. The end face of the connecting rod 240 is connected to the end wall of the limiting strip 251 by a second spring 256.
[0032] The above embodiment provides a waterproof electronic connector, wherein the front end of the socket body 100 is inserted into the insertion slot 210 and a tight connection is achieved through a threaded engagement between the outer wall of the stepped portion 130 and the inner wall of the insertion slot 210; the end face of the pressure plate 120 abuts against the front end face of the plug portion 200, and the portion of the plug portion 200 in contact with the pressure plate 120 covers the outside of the drainage groove 140; at this time, the receiving opening 221 is opposite to the drainage groove 140 and the airbag 222 is recessed inside the annular chamber 220; the pressure regulating component increases the air pressure inside the annular chamber 220, and the increased air pressure in the annular chamber 220 allows the airbag 222 to extend into the drainage groove 140 and... The airbag 222 bulges up, thus sealing the gap between the stepped portion 130 and the inner wall of the plug slot 210, effectively increasing the sealing between the socket body 100 and the plug slot 210. Water stains on the outside of the socket body 100 and the plug portion 200 may enter the drain groove 140 through the part of the plug portion 200 that contacts the pressure plate 120. Most of the water stains flow out through the drain hole 160. At the same time, the airbag 222 can seal the gap between the stepped portion 130 and the inner wall of the plug slot 210, preventing water stains from entering the part of the contact groove 211 that contacts the electrical contact through the gap between the socket body 100 and the plug slot 210, thereby effectively improving the waterproof effect.
[0033] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
