Description

Technical Field

[0001] This invention belongs to the field of electrical connector technology, and particularly relates to a coaxial wall conductive connector with a Glyd ring sealing structure. Background Technology

[0002] Electrical connectors are core components ensuring circuit continuity and signal transmission. Coaxial wall-mounted conductive connectors achieve conductivity through contact between the plug and the wall electrodes of the socket, fulfilling core requirements such as multi-channel conductivity, mechanical fixation, and coaxial mounting matching. In complex operating environments such as outdoors, high humidity, and dust, connectors must possess reliable waterproof and dustproof performance to ensure long-term stable operation of equipment. However, connectors with conventional structures often fail to meet the protection standards in practical applications due to inadequate sealing designs.

[0003] Existing coaxial wall conductive connectors consist of a plug and a socket that are inserted into each other. They use multiple electrodes evenly distributed around the circumference to achieve independent conductivity in multiple paths. O-ring grooves are machined on both sides of the plug electrodes and O-ring seals are installed. After the plug and socket are inserted, the seals are compressed to form an annular sealing area, thereby achieving waterproof and dustproof protection for the electrode area. Although this solves the problems of small contact area, easy misalignment during assembly, and basic sealing of traditional pin connectors, there are still obvious defects in actual use due to the unreasonable arrangement of the sealing structure and conductive contact structure.

[0004] Specifically, the core flaw of the aforementioned prior art lies in the fact that the sealing structure is located on the plug, and the O-ring at the front of the plug must pass through the socket electrode in an elastically contracted state to complete the insertion seal. This easily leads to O-ring wear and seal failure. On the one hand, the sealing structure and the conductive contact structure interfere with each other. During insertion and removal, the O-ring on the plug side must pass through the socket electrode in an elastically contracted state. The O-ring is easily scratched and squeezed by the edge of the socket electrode, resulting in wear, scratches, deformation, or even detachment. This leads to a short service life of the seal, easy failure, and inability to guarantee long-term waterproof and dustproof performance. On the other hand, the seal is installed on one side of the plug, and the insertion and removal actions directly affect the sealing reliability. After repeated insertion and removal, the sealing performance will significantly degrade, requiring frequent maintenance. In summary, the arrangement of the seal and the elastic electrode in the prior art presents a structural contradiction, resulting in poor sealing reliability, high maintenance costs, and difficulty in meeting the requirements for long-term stable operation in harsh working environments. Summary of the Invention

[0005] This invention provides a coaxial wall conductive connector with a Glyd ring sealing structure to solve the technical problem that the seals in existing electrical connectors are easily worn by the elastic electrodes, leading to seal failure; and how to achieve complete separation and non-interference between the sealing and conductive structures, thereby extending the service life of the seals, while ensuring that the elastic electrodes of the socket reliably press against the plug electrodes and achieve stable conductivity.

[0006] To address the aforementioned technical problems, this invention provides a coaxial wall conductive connector with a Glyd ring sealing structure, comprising a plug body, a plug wire, a plug handle, a plug electrode skeleton, and plug electrodes; the plug electrodes are uniformly embedded circumferentially in the circumferential positioning grooves of the plug electrode skeleton, and each core wire of the circumferential positioning groove is welded to the corresponding plug electrode to form an independent conductive branch; the plug handle covers the outside of the plug electrode skeleton; the outer circumferential end face of the plug electrode skeleton is provided with a sliding outer circle; a D-shaped anti-rotation hole is opened at the center of the sliding outer circle;

[0007] The socket body includes a socket handle, socket electrodes, a socket electrode frame, and socket wires. The socket electrodes are fitted into stepped holes on the outer circumference of the socket electrode frame and contract inward under the elastic force of the socket handle, making the diameter of the hole formed by the inner surface of the socket electrodes smaller than the outer diameter of the socket electrodes. Each core wire of the socket wire is welded to the corresponding socket electrode to form an independent conductive path. A D-shaped guide rod is provided at the center of the socket electrode frame, and the D-shaped guide rod cooperates with the D-shaped anti-rotation hole to achieve anti-rotation and coaxial positioning.

[0008] A first glyph ring is provided at the front end of the socket electrode, and a second glyph ring is provided at the rear end of the socket electrode. The first glyph ring and the second glyph ring are tightly fitted with the inner wall of the socket body to form a double-sealed isolation cavity, which completely encloses the socket electrode in the double-sealed isolation cavity.

[0009] The first and second Glyd rings have the same structure, both including a rubber O-ring and a polytetrafluoroethylene (PTFE) wear-resistant slip ring; the rubber O-ring provides an initial radial pre-compression force to make the PTFE wear-resistant slip ring fit tightly against the outer circle of the slip ring to form an initial seal; after the plug body and the socket body are inserted, the socket electrode tightly presses against the plug electrode to form multiple independent conductive paths, while the first and second Glyd rings form a double sealing protection.

[0010] Optionally, the plug body is further provided with a D-shaped vent hole, which is connected to the D-shaped anti-rotation hole, and is used to discharge internal air during the insertion process to reduce insertion and removal resistance.

[0011] Optionally, the socket handle is injection molded from an elastic insulating material. The inner wall of the socket handle is provided with an axial positioning step and a semi-cylindrical positioning protrusion. The side wall of the socket handle is provided with a small vent hole. The small vent hole can expel air during the insertion and removal of the plug body and the socket body, thereby reducing the insertion and removal resistance. The socket electrode skeleton is made of a high-strength insulating material.

[0012] Optionally, the outer circle of the sliding ring is prepared with a smooth layer through precision machining or precision injection molding, forming a smooth surface with the polytetrafluoroethylene wear-resistant slip rings of the first and second Glyd rings, so as to avoid scratching the polytetrafluoroethylene wear-resistant slip rings during insertion and removal.

[0013] Optionally, a mounting ring groove is reserved at the front and rear positions of the socket electrode skeleton and the socket handle. The first glyph and the second glyph are installed in the mounting ring groove. After installation, the first glyph and the second glyph are coaxially arranged with the socket electrode and the D-shaped guide rod.

[0014] Optionally, the socket electrode maintains a preset distance from the first and second glyphs in the axial direction, such that the elastic contraction deformation of the socket electrode does not interfere with the sealing function of the first and second glyphs.

[0015] Optionally, both the plug electrode and the socket electrode are made of a highly conductive alloy material, and both the surface of the plug electrode and the surface of the socket electrode are provided with an anti-corrosion layer.

[0016] In this invention, by transferring the sealing structure from the plug body to the inside of the socket body, and replacing the O-ring with a first and second Glyd ring, the Glyd ring is positioned on both sides of the elastic socket electrode without contacting it. This completely solves the problem of O-rings being scratched and worn by the elastic electrode in the prior art. At the same time, the outer circle is precision-machined to have high-precision dimensions, high roundness, and high surface finish, forming a smooth sliding fit with the PTFE wear-resistant slip rings of the first and second Glyd rings. There is no scraping or squeezing wear, which fully utilizes the wear-resistant sealing advantages of the PTFE slip ring, significantly extends the service life of the sealing component, ensures long-term stable sealing effect, low insertion and extraction resistance, and smooth operation.

[0017] This invention achieves complete separation and non-interference between the sealing and conductive structures: the first and second Glyphs within the socket body independently perform the sealing function of the connector, while the flexible socket electrode performs the conductive function. These two structures are arranged in separate zones without interference, ensuring both the sealing effect of the Glyphs and the reliable compression of the flexible socket electrode to the plug electrode for stable conductivity. The front and rear double Glyphs form a double-seal protection, completely enclosing the flexible socket electrode area within the sealed cavity. The Glyphs provide bidirectional sealing, effectively preventing moisture and dust from entering through the insertion gap at the front end of the socket body and the wire exit gap at the rear end. Compared to the single O-ring seal of existing technologies, this provides a higher level of protection and is suitable for use in [other applications]. Suitable for harsh environments such as outdoor use, rain, high humidity, and dust, and adaptable to different internal pressure scenarios, it offers enhanced sealing stability. Furthermore, the socket body's installation dimensions, anti-rotation guide structure, and conductive structure remain consistent with existing connectors of the same specifications. The plug body only optimizes the precision of the sliding outer circle without altering the overall structure and dimensions, allowing direct replacement of existing sockets of the same specifications without requiring equipment modifications, thus reducing upgrade costs. The two Glyd rings can be independently removed and replaced from inside the socket body without disassembling the elastic socket electrodes, socket wires, or replacing the entire socket body, nor is it necessary to replace the plug body. Maintenance is simple and cost-effective, and the plug body is reusable, significantly extending its service life. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] like Figures 1 to 4As shown, an embodiment of the present invention provides a coaxial wall conductive connector with a Glyd ring sealing structure, including a plug body 1, a plug wire 101, a plug handle 102, a plug electrode skeleton 103, and plug electrodes 104; the plug electrodes 104 are uniformly embedded in the circumferential positioning grooves of the plug electrode skeleton 103, and each core wire of the circumferential positioning groove is welded to the corresponding plug electrode 104 to form an independent conductive branch; the plug handle 102 covers the outside of the plug electrode skeleton 103; the outer circumferential end face of the plug electrode skeleton 103 is provided with a sliding outer circle 107; the center of the sliding outer circle 107 is provided with a D-shaped anti-rotation hole 106.

[0029] The socket body 2 includes a socket handle 201, a socket electrode 202, a socket electrode frame 203, and a socket wire 204. The socket electrode 202 is fitted into a stepped hole on the outer circumference of the socket electrode frame 203 and contracts inward under the elastic force of the socket handle 201, so that the diameter of the hole formed by the inner surface of the socket electrode 202 is smaller than the outer diameter of the socket electrode 202. Each core wire of the socket wire 204 is welded to the corresponding socket electrode 202 to form an independent conductive path. A D-shaped guide rod 206 is provided at the center of the socket electrode frame 203. The D-shaped guide rod 206 cooperates with the D-shaped anti-rotation hole 106 to achieve anti-rotation and coaxial positioning.

[0030] A first glyph ring 3 is provided at the front end of the socket electrode 202, and a second glyph ring 4 is provided at the rear end of the socket electrode 202. The first glyph ring 3 and the second glyph ring 4 are tightly fitted with the inner wall of the socket body 2 to form a double-sealed isolation cavity, completely enclosing the socket electrode 202 in the double-sealed isolation cavity.

[0031] The first Glyd ring 3 and the second Glyd ring 4 have the same structure, both including a rubber O-ring 301 and a polytetrafluoroethylene wear-resistant slip ring 302; the rubber O-ring 301 provides an initial radial pre-compression force so that the polytetrafluoroethylene wear-resistant slip ring 302 is tightly attached to the outer circle 107 to form an initial seal; after the plug body 1 and the socket body 2 are inserted, the socket electrode 202 tightly presses the plug electrode 104 to form multiple independent conductive paths, while the first Glyd ring 3 and the second Glyd ring 4 form a double sealing protection.

[0032] In one embodiment, such as Figure 2As shown, the plug body 1 is also provided with a D-shaped vent hole 105, which communicates with the D-shaped anti-rotation hole 106, and is used to expel internal air during the insertion process to reduce insertion and removal resistance. Understandably, the D-shaped vent hole 105 is provided on the plug body 1 and communicates with the D-shaped anti-rotation hole 106. During the insertion process between the plug body 1 and the socket body 2, internal air can be expelled through the channel formed by the D-shaped vent hole 105 and the D-shaped anti-rotation hole 106, thereby reducing insertion and removal resistance and making the insertion and removal operation smoother. Simultaneously, the small vent hole 205 on the side wall of the socket handle 201 can also expel air during the insertion process to reduce insertion and removal resistance. The two work together to ensure that the plug body 1 can be smoothly inserted into the socket body 2 and form an effective seal with the first Glycol ring 3 and the second Glycol ring 4, avoiding problems such as difficulty in insertion and removal or inadequate sealing due to internal air pressure accumulation.

[0033] In one embodiment, such as Figure 3 As shown, the socket handle 201 is injection molded from elastic insulating material. The inner wall of the socket handle 201 is provided with an axial positioning step (not shown) and a semi-cylindrical positioning protrusion (not shown). The side wall of the socket handle 201 is provided with a small exhaust hole 205. The small exhaust hole 205 can discharge air during the insertion process of the plug body 1 and the socket body 2, reducing the insertion and removal resistance. The socket electrode skeleton 203 is made of high-strength insulating material. Understandably, the socket handle 201 is injection molded from an elastic insulating material. Its inner wall is provided with an axial positioning step and a semi-cylindrical positioning protrusion, and the side wall is provided with a small vent hole 205. The vent hole 205 can expel internal air during the insertion process of the plug body 1 and the socket body 2 to reduce insertion and removal resistance. At the same time, the socket electrode skeleton 203 is made of high-strength insulating material. The two work together to ensure the structural strength and assembly accuracy of the socket body 2. The elastic insulating material gives the socket handle 201 the ability to elastically contract, so that the socket electrode 202 assembled inside can contract inward and tightly press the plug electrode 104 to achieve reliable conductivity. The axial positioning step and the semi-cylindrical positioning protrusion cooperate with the socket electrode skeleton 203 to achieve axial and radial positioning, ensuring that the assembly is firm and the coaxiality meets the standard, avoiding the loosening of parts during use, and ensuring the stability of the fit between the first glyph 3 and the second glyph 4 and the sliding outer circle 107 of the plug body 1.

[0034] In one embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the outer sliding circle 107 is prepared with a smooth layer by precision machining or precision injection molding, forming a smooth surface with the polytetrafluoroethylene wear-resistant slip ring 302 of the first Glyd ring 3 and the second Glyd ring 4, so as to avoid scratching the polytetrafluoroethylene wear-resistant slip ring 302 during insertion and removal. Understandably, the outer sliding circle 107 is prepared with a smooth layer through precision machining or precision injection molding, forming a smooth surface with the PTFE wear-resistant slip ring 302 of the first Glyd ring 3 and the second Glyd ring 4. This avoids scratching the PTFE wear-resistant slip ring 302 during insertion and removal, thereby ensuring the integrity of the Glyd ring sealing structure and the long-term stability of the sealing performance. Since the PTFE wear-resistant slip ring 302 is the core component for achieving sealing in the Glyd ring, its surface integrity directly determines the sealing reliability. The high smoothness of the outer sliding circle 107 effectively eliminates the defect of O-rings being scratched and worn by elastic electrodes in the prior art, allowing the plug body 1 to be repeatedly inserted and removed without damaging the sealing element, greatly extending the sealing life and ensuring the waterproof and dustproof effect of the connector in harsh environments such as outdoors, humidity, and dust.

[0035] In one embodiment, such as Figure 1 and Figure 3 As shown, the socket electrode skeleton 203 and the socket handle 201 have pre-reserved mounting ring grooves at their front and rear positions. The first glyph 3 and the second glyph 4 are installed in the mounting ring grooves. After installation, the first glyph 3 and the second glyph 4 are coaxially arranged with the socket electrode 202 and the D-shaped guide rod 206. Understandably, mounting ring grooves are reserved at the front and rear positions of the mating point between the socket electrode skeleton 203 and the socket handle 201. The first glyph 3 and the second glyph 4 are installed in the mounting ring grooves and, after installation, are coaxially arranged with the socket electrode 202 and the D-shaped guide rod 206. This ensures that the two sets of glyphs form a uniform radial sealing contact with the sliding outer circle 107 of the plug body 1, avoiding local sealing failure or abnormal wear of the PTFE wear-resistant slip ring 302 due to eccentricity or tilt. At the same time, this coaxial arrangement ensures that the sliding outer circle 107 can smoothly pass through the first glyph 3 and the second glyph 4 without scraping when the plug body 1 is inserted. This allows the glyphs to form a symmetrical and reliable double-seal isolation cavity before and after the elastic socket electrode 202, completely enclosing the socket electrode 202 in the sealing cavity and completely cutting off the intrusion path of water vapor and dust from the front insertion gap or the rear wire lead-out gap.

[0036] In one embodiment, such as Figures 1 to 3As shown, the socket electrode 202 maintains a preset distance from the first Glyph 3 and the second Glyph 4 in the axial direction. This preset distance ensures that the elastic contraction and deformation of the socket electrode 202 does not interfere with the sealing function of the first Glyph 3 and the second Glyph 4. Understandably, the socket electrode 202 is elastic. The socket electrode 202 maintains a preset distance from the first glyph 3 and the second glyph 4 in the axial direction. This preset distance ensures that the elastic contraction and deformation of the socket electrode 202 does not interfere with the sealing function of the first glyph 3 and the second glyph 4, thereby achieving complete separation of the sealing and conductive structures. Specifically, the socket electrode 202 contracts inward under the elastic force of the socket handle 201 to tightly press the plug electrode 104 to achieve reliable conductivity, while the glyphs at both ends of its axial direction independently undertake the waterproof and dustproof sealing function. The two are arranged in separate sections and do not contact each other, which avoids the scratching and wear problem caused by the sealing element passing through the elastic electrode in the prior art, and ensures that the elastic socket electrode 202 can deform freely to maintain a stable contact pressure. At the same time, it protects the glyphs from the interference of the elastic deformation of the electrode and keeps them in a complete sealing state.

[0037] In one embodiment, such as Figures 1 to 3 As shown, both the plug electrode 104 and the socket electrode 202 are made of high-conductivity alloy material, and an anti-corrosion layer is provided on the surface of both the plug electrode 104 and the socket electrode 202. Understandably, the use of high-conductivity alloy material for both the plug electrode 104 and the socket electrode 202, along with the anti-corrosion layer on their surfaces, improves conductivity stability and service life. The high-conductivity alloy material ensures a large-area reliable contact between the plug electrode 104 and the socket electrode 202, reducing contact resistance and guaranteeing the signal or high-current transmission quality of multiple independent conductive paths. The anti-corrosion layer effectively isolates moisture and dust, reducing electrode oxidation and electrochemical corrosion. Especially in harsh working environments such as outdoors, in humid conditions, and with high dust levels, this anti-corrosion treatment works synergistically with the front and rear double Dougline sealing structure to keep the electrode area in a sealed and protected state for a long time.

[0038] In one specific embodiment, before the plug body 1 and the socket body 2 are plugged in, the manufacturing process of the plug body 1 is as follows: each core wire of the plug wire 101 is welded to the corresponding plug electrode 104 to form an independent conductive branch. The welded plug electrode 104 is embedded in the circumferential positioning groove of the plug electrode skeleton 103 to achieve circumferential uniform arrangement and fixation. The plug handle 102 is wrapped around the outside of the plug electrode skeleton 103 by injection molding process. The dimensional accuracy, roundness and surface finish of the outer circle 107 are strictly controlled to ensure that it is smooth and burr-free. At the same time, the D-shaped hole in the center of the plug handle 102 is kept coaxial with the D-shaped anti-rotation hole 106 in the center of the plug electrode skeleton 103, and the D-shaped hole vent 105 is connected to the D-shaped anti-rotation hole 106.

[0039] The manufacturing process of the socket body 2 is as follows: The socket electrode skeleton 203 is processed by injection molding. Electrode mounting step holes are processed on its outer circular surface and a D-shaped guide rod 206 is set in the center. The elastic socket electrodes 202 are assembled one by one into the step holes, so that the elastic socket electrodes 202 contract inward under the elastic force of the socket handle 201. Each core wire of the socket wire 204 is welded to the corresponding elastic socket electrode 202 to form an independent conductive path. A glyph mounting ring groove is reserved at the front and rear positions of the socket electrode skeleton 203 and the socket handle 201. The first glyph 3 and the second glyph 4 are pressed into the front and rear mounting ring grooves respectively to ensure that the two sets of glyphs are coaxial and fit tightly against the inner wall of the socket body 2. Finally, the welded elastic socket electrodes 202, socket electrode skeleton 203, and socket wire 204 are pressed into the socket handle 201 as a whole. Axial and radial positioning is achieved by the axial positioning step, semi-cylindrical positioning protrusion and trapezoidal ring groove of the inner wall of the socket handle 201 in cooperation with the socket electrode skeleton 203.

[0040] The mating process of the plug body 1 and the socket body 2 is as follows:

[0041] During insertion, align the D-shaped anti-rotation hole 106 of the plug body 1 with the D-shaped guide rod 206 of the socket body 2, and slowly insert it. The D-shaped structure provides anti-rotation and coaxial guidance, ensuring precise alignment of the plug electrode 104 and the flexible socket electrode 202, preventing poor contact due to electrode misalignment. It also ensures coaxial alignment of the plug body 1 with the first and second glyphs 3 and 4, preventing scratches on the glyphs. During insertion, the sliding outer circle 107 passes sequentially through the first glyph 3 at the front end of the socket body 2, the flexible socket electrode 202, and the second glyph 4 at the rear end. Due to its high precision and smooth surface, the sliding outer circle 107 forms a smooth surface fit with the PTFE wear-resistant slip ring 302 of the first and second glyphs 3 and 4, preventing scratches and wear. The glyphs remain intact, fully utilizing their wear-resistant sealing advantages to ensure stable sealing performance. When the plug handle 102 is in contact with the end face of the socket handle 201, the plug electrode 104 and the flexible socket electrode 202 achieve a large-area tight fit. With tight contact, the flexible socket electrode 202, under the action of its own elasticity and the socket handle 201, firmly presses the plug electrode 104, forming multiple independent and stable conductive paths to meet the transmission requirements of signals or high currents, achieving the coordinated work of sealing and conductivity. After insertion, the first glyph 3 and the second glyph 4 completely seal the area of ​​the flexible socket electrode 202, forming a double seal protection, which can effectively prevent moisture and dust from entering from the insertion gap at the front end of the socket body 2 or the wire lead-out gap at the rear end, achieving a high level of waterproof and dustproof effect. At the same time, the glyphs can achieve bidirectional sealing, further improving the sealing reliability. After repeated insertion and removal, if the first glyph 3 or the second glyph 4 is worn, it can be directly removed from the inside of the socket body 2 and the glyph can be replaced without disassembling the flexible socket electrode 202, the socket wire 204, or replacing the entire socket body 2, nor is it necessary to replace the plug body 1. The maintenance operation is simple and the maintenance cost is low. The plug body 1 can be reused, and its service life is greatly improved.
