Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and in particular to a coaxial mounting wall conductive connector and its manufacturing method. Background Technology

[0002] Electrical connectors are core components in electromechanical equipment that enable circuit connections and signal transmission. They typically employ a pin-and-socket mating structure to achieve electrical signal connection. Existing coaxial mounting wall conductive connectors are mostly single-wall, single-electrode structures, primarily used in equipment with coaxial mounting wall structures. They must meet the basic requirements of conductive contact on both sides of the wall, mechanical fixation, and compatibility with coaxial mounting dimensions.

[0003] A typical wall-mounted conductive connector generally consists of a ring-shaped contact electrode or a cylindrical conductive rod and a fixing structure. Current / signal conduction is achieved by connecting the contact electrode and the conductive rod. The fixing structure secures the connector to the mounting wall, and the electrode and conductive rod are connected to external wires.

[0004] Existing technologies mostly employ integrated conductive mandrels without multi-channel contact structures, enabling only single-channel current / signal transmission. This fails to meet the requirements for two or more channels of electrical or signal transmission, resulting in poor adaptability. The connection between the conductive contact spring and the integrated conductive mandrel is a one-sided conduction type, which is limited by manufacturing processes and makes it difficult to achieve large-area contact. This also prevents efficient utilization of the conductive surface of the conductive mandrel, leading to low conductivity and making it difficult to meet the requirements of high-current conduction applications. Furthermore, the lack of a dedicated anti-rotation guiding structure makes it prone to rotational misalignment during assembly, resulting in poor conductive contact and affecting the stability of signal / current transmission. The absence of a venting structure prevents internal gases from escaping during assembly, increasing assembly resistance and easily leading to component misalignment and damage. Additionally, the lack of standardized manufacturing and assembly processes makes it difficult to ensure product dimensional consistency, which is detrimental to mass production. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a coaxial mounting wall conductive connector and its manufacturing method, which can achieve coaxial mounting, side wall conductivity, multi-channel conduction, and anti-rotation positioning functions. It is suitable for electromechanical equipment that requires multi-channel current / signal transmission on both sides of the coaxial mounting wall.

[0006] This invention provides a coaxial mounting wall conductive connector, including a plug and a socket.

[0008] Optionally, a circular hole is provided on the lower side wall of the socket handle and the root side wall of the hole at the center of the plug handle for venting.

[0009] Optionally, the inner wall of the socket handle is provided with the same number of semi-cylindrical protrusions as the plug electrodes in the circumferential direction at the middle and bottom. The semi-cylindrical protrusions in the middle are in elastic contact with the outer surface of the socket electrodes to realize the axial displacement of the socket electrodes. The semi-cylindrical protrusions at the bottom are matched with the wire placement groove to realize radial positioning.

[0010] Optionally, the guide rod extends beyond the socket electrode frame, and the top end of the guide rod is tapered.

[0011] Optionally, the outer surfaces of the plug handle and the socket handle are provided with annular protrusions.

[0012] This invention also provides a method for manufacturing a coaxial mounting wall conductive connector, comprising the following steps: The same number of fixing grooves as the plug electrode are evenly opened in the circumferential direction on the circumferential surface of the plug electrode skeleton, and a through hole with a D-shaped cross-section is opened in the center of the plug electrode skeleton. The core wires of the plug wire are soldered to the plug electrodes to form independent conductive branches. The soldered plug electrodes are then embedded into the fixing grooves on the circumferential surface of the plug electrode skeleton to achieve uniform circumferential distribution and positioning. The plug handle is formed by mold casting or injection molding. The center of the plug handle has a hole with the same shape as the center of the plug motor frame. A round hole for venting is opened on the side wall at the root of the hole. The through hole of the plug electrode frame and the hole of the plug handle are connected to form a plug D-shaped hole. The socket handle is made of elastic insulating material. The inner wall of the socket handle has a number of semi-cylindrical protrusions that are evenly distributed around the middle and bottom circumference, the same number as the plug electrodes. The inner wall of the socket handle has a trapezoidal annular groove, and the lower side wall of the socket handle has a circular hole for venting. The socket electrode skeleton is made of high-hardness insulating material. The socket electrode skeleton has the same number of socket electrode mounting step holes as the plug electrode evenly opened on the circumferential wall. Each hole has a wire placement groove matching the wire diameter at its root. The outer circumferential surface of the socket electrode skeleton is provided with trapezoidal annular protrusions. The center of the socket electrode skeleton is provided with a guide rod with the same cross-sectional shape as the central through hole of the plug motor skeleton, which is used to cooperate with the D-shaped hole of the plug to achieve anti-rotation and coaxial guidance. The socket wire is welded to the socket electrode to form a conductive path. The socket electrode is installed in the socket electrode mounting step hole, and the socket wire is embedded in the wire placement groove. The socket wire, the socket electrode, and the socket electrode skeleton are inserted axially into the socket handle as a whole. The semi-cylindrical protrusion at the bottom of the inner wall of the socket handle matches the groove for placing the wire to achieve radial positioning. The semi-cylindrical protrusion in the middle of the inner wall of the socket handle makes elastic contact with the outer surface of the socket electrode to achieve axial displacement of the socket electrode.

[0015] Optionally, the following steps are also included: The plug electrodes are made of highly conductive material and have been treated with anti-corrosion coating.

[0016] The above technical solution has the following technical effects: 1. Enables independent conduction of multiple channels to meet multi-channel transmission requirements. By adopting a circumferentially distributed multi-electrode independent design, replacing the traditional integrated single conductive spindle, it can transmit two or more current / signal channels simultaneously, greatly expanding the applicable range.

[0017] 2. Large conductive contact area, suitable for high current conduction. By using a large-area contact between the plug electrodes and socket electrodes, the conductive surface is fully utilized, resulting in stronger current carrying capacity, lower heat generation, and higher conduction efficiency, thus solving the bottleneck of traditional single-circuit small contact area conduction.

[0018] 3. D-shaped anti-rotation guide, high coaxiality, and stable contact. The D-shaped hole and D-shaped guide rod are forcibly positioned and matched, ensuring that the electrodes can be inserted without rotational misalignment, accurately aligned, and will not loosen or spark even after long-term use.

[0019] 4. Reliable assembly and positioning, and strong overall structural integrity. The trapezoidal engagement and semi-cylindrical groove provide dual positioning, preventing axial movement and radial offset of internal components, significantly improving mechanical stability and vibration resistance.

[0020] 5. Simple manufacturing process, good consistency, and suitable for mass production. The integrated process of mold casting / injection molding, insertion, and press fitting reduces processing difficulty, ensures good dimensional consistency, and achieves a high yield rate, thus solving the processing limitations of traditional structures.

[0021] 6. Equipped with a venting / wiring structure for smooth assembly. The socket and plug handles have round holes on the side walls, allowing internal gas to escape during press-fitting, resulting in low resistance, neat wire arrangement, and no compression damage.

[0037] The plug handle is cylindrical and made of insulating material. The plug electrode skeleton is cylindrical and made of high-temperature resistant insulating material.

[0039] The plug electrode includes multiple plug electrodes, and the specific number can be set as needed.

[0040] The plug electrode skeleton has a number of fixing slots evenly distributed around its circumference, the same number as the plug electrode, and the plug electrode is embedded in the fixing slots of the plug electrode skeleton.

[0041] The plug wires include the same number of plug wires as the plug electrodes. The core wires of the plug wires are soldered to the plug electrodes to form independent conductive branches.

[0042] Figure 4 This is a schematic cross-sectional view of the coaxial mounting wall conductive connector socket in an embodiment of the present invention. Figure 5This is a cross-sectional schematic diagram of the coaxial mounting wall conductive connector socket in an embodiment of the present invention. Figure 4 and Figure 5 As shown, the coaxial mounting wall conductive connector socket further includes a socket handle 201, a socket electrode 202, a socket electrode frame 203, and a socket wire 204.

[0043] The socket handle is a hollow cylinder made of elastic insulating material. The socket electrode frame is a cylinder made of high-hardness insulating material. The outer diameter of the socket electrode frame is the same as the inner diameter of the socket handle. The socket electrode frame is installed inside the socket handle, and the tops of the socket handle and the socket electrode frame are flush.

[0044] The upper part of the socket electrode frame is a hollow structure. The inner diameter of the socket electrode frame is the same as the outer diameter of the plug electrode frame, and the length of the hollow structure at the top of the socket electrode frame is the same as the length of the plug electrode frame.

[0045] The socket electrode skeleton has the same number of socket electrode mounting step holes as the plug electrode evenly distributed around its circumference. A wire placement groove is formed at the bottom of the socket electrode skeleton to connect each socket electrode mounting step hole.

[0046] A guide rod 507, with a cross-sectional shape identical to the central through hole of the plug motor frame, is positioned at the upper center of the socket electrode frame. The length of the guide rod is the same as the sum of the lengths of the central through hole of the plug motor frame and the central hole of the plug handle. Therefore, the guide rod matches the central through hole of the plug motor frame and the central hole of the plug handle. In one embodiment, the guide rod extends beyond the socket electrode frame, and the top of the guide rod is tapered.

[0047] The socket electrode includes the same number of socket electrodes as the plug electrode. The socket electrodes are respectively installed in the socket electrode mounting step hole. The same number of socket electrodes and plug electrodes are matched in position and connected to form a conductive path.

[0048] The socket wires include the same number of socket wires as the plug electrodes. The socket wires are embedded in the wire placement grooves. The core wires of the socket wires are soldered to the socket electrodes at soldering points 502 to form independent conductive branches.

[0049] In one embodiment, a trapezoidal annular protrusion 501 is provided on the outer circumference of the socket electrode skeleton, and a trapezoidal annular groove 503 is provided on the inner wall of the socket handle, with the trapezoidal annular protrusion and the trapezoidal annular groove being matched in position.

[0050] In one embodiment, a circular hole 505 is provided on the lower side wall of the socket handle for venting.

[0051] In one embodiment, the same number of semi-cylindrical protrusions as the plug electrodes are evenly arranged in the middle and bottom circumferential direction on the inner wall of the socket handle. The semi-cylindrical protrusions 504 in the middle are in elastic contact with the outer surface of the socket electrodes to realize the axial displacement of the socket electrodes. The semi-cylindrical protrusions 506 at the bottom are matched with the wire placement grooves to realize radial positioning.

[0052] In one embodiment, the outer surfaces of the plug handle and the socket handle are provided with annular protrusions, which can help prevent the plug from slipping when inserted into the socket.

[0053] The manufacturing process of the coaxial mounting wall conductive connector described above is described below.

[0054] Figure 6 This is a flowchart illustrating the manufacturing process of the coaxial mounting wall conductive connector in an embodiment of the present invention. Figure 6 The pattern, the process includes the following steps: Step 101: Evenly open the same number of fixing grooves as the plug electrode on the circumferential surface of the plug electrode skeleton, and open a through hole with a D-shaped cross-section at the center of the plug electrode skeleton.

[0055] Step 102: Solder the core wires of the plug conductors to the plug electrodes to form independent conductive branches. Embed the soldered plug electrodes into the fixing grooves on the circumferential surface of the plug electrode skeleton to achieve uniform circumferential distribution and positioning.

[0056] Step 103: The plug handle is formed by mold casting or injection molding. A hole with the same shape as the center of the plug motor frame is formed in the center of the plug handle. A round hole for venting is opened on the side wall at the root of the hole. The through hole of the plug electrode frame and the hole of the plug handle are connected to form a plug D-shaped hole.

[0057] Step 104: The socket handle is made of elastic insulating material. The middle and bottom of the inner wall of the socket handle are uniformly provided with the same number of semi-cylindrical protrusions as the plug electrodes. A trapezoidal annular groove is opened on the inner wall of the socket handle, and a round hole for venting is opened on the lower side wall of the socket handle.

[0058] Step 105: The socket electrode skeleton is made of high-hardness insulating material. The same number of socket electrode mounting step holes as the plug electrode are evenly opened on the circumferential wall of the socket electrode skeleton. Each hole has a wire placement groove matching the wire diameter at the root. The outer circumferential surface of the socket electrode skeleton is provided with trapezoidal annular protrusions.

[0059] Step 106: A guide rod with the same cross-sectional shape as the central through hole of the plug motor frame is set at the center of the socket electrode skeleton. This guide rod is used to cooperate with the D-shaped hole of the plug to achieve anti-rotation and coaxial guidance.

[0060] In this step, the guide rod can extend beyond the socket electrode frame, and the top of the guide rod can be set to a tapered shape.

[0061] Step 107: Weld the socket wire to the socket electrode to form a conductive path. Install the socket electrode in the socket electrode mounting step hole and embed the socket wire into the wire placement groove.

[0062] Step 108: Insert the socket wire, socket electrode, and socket electrode skeleton into the socket handle as a whole along the axial direction. The semi-cylindrical protrusion at the bottom of the inner wall of the socket handle matches the wire placement groove to achieve radial positioning. The semi-cylindrical protrusion in the middle of the inner wall of the socket handle makes elastic contact with the outer surface of the socket electrode to achieve axial displacement of the socket electrode. The trapezoidal annular protrusion on the outer circumference of the socket electrode skeleton engages with the trapezoidal annular groove on the inner wall of the socket handle to achieve axial positioning.

[0063] After assembly, the structure is stable, has high coaxiality, and is not easy to loosen.

[0064] In one embodiment, annular protrusions may also be provided on the outer surface of the plug handle and the socket handle for anti-slip purposes.

[0065] In one embodiment, the plug electrodes can be made of highly conductive material and have an anti-corrosion treatment on the surface to improve conductivity stability and service life.

[0066] When the plug of the coaxial mounting wall conductive connector is inserted into the socket, the guide rod extending from the socket electrode skeleton first enters the central through hole of the plug motor skeleton. Since the top of the guide rod is tapered, it is easy to align and insert. Furthermore, due to the D-shaped cross-section of the guide rod, it is only allowed to be inserted into the central through hole of the plug motor skeleton at one angle.

[0067] Guided by the guide rod, the plug electrode skeleton is also inserted into the socket electrode skeleton. During the insertion process, the air squeezed by the guide rod in the central through hole of the plug motor skeleton is discharged through the round hole opened on the side wall of the hole root in the center of the plug handle. At the same time, the air squeezed by the plug electrode skeleton in the socket electrode skeleton is discharged through the round hole opened on the side wall of the lower end of the socket handle, thereby reducing resistance and ensuring that the plug and socket are fully inserted.

[0068] When the guide rod is inserted to the bottom of the center hole of the plug handle, the plug is fully inserted into the socket, and the end face of the plug handle and the end face of the socket handle are in contact. In this state, the same number of socket electrodes and plug electrodes are matched, corresponding to each other, and the maximum contact area is achieved.

[0069] Because the semi-cylindrical protrusion in the middle of the inner wall of the socket handle makes elastic contact with the outer surface of the socket electrode, the socket electrode can be displaced axially and connected separately, so that the socket electrode and the plug electrode can be in close contact, thereby forming multiple conductive paths.

[0070] In the above embodiments, a multi-electrode arrangement with evenly distributed circumference is adopted to achieve parallel transmission of current / signal in two or more channels, breaking through the limitations of traditional single-core integrated structures. The D-shaped hole of the plug and the D-shaped guide rod of the socket cooperate to achieve precise coaxial positioning, anti-torsion, and anti-misalignment, improving contact reliability. The electrode skeleton is responsible for positioning and support, while the elastic handle is responsible for sealing, buffering, and assembly fixation, taking into account both strength and adaptability. The dual positioning structure of trapezoidal annular protrusion plus trapezoidal annular groove and semi-cylindrical protrusion plus wire placement groove achieves reliable axial and radial positioning of the internal components of the socket, without movement or offset. The overall manufacturing and assembly method adapted to the coaxial mounting wall includes a complete set of processes such as welding, embedding, mold casting / injection, and overall press-fit positioning. The venting / wiring structure with side wall circular holes facilitates assembly venting and internal wire arrangement, reducing assembly resistance.

The center of the socket electrode skeleton is provided with a guide rod with the same cross-sectional shape as the central through hole of the plug motor skeleton, which is used to cooperate with the D-shaped hole of the plug to achieve anti-rotation and coaxial guidance. The socket wire is welded to the socket electrode to form a conductive path. The socket electrode is installed in the socket electrode mounting step hole, and the socket wire is embedded in the wire placement groove. The socket wire, the socket electrode, and the socket electrode skeleton are inserted axially into the socket handle as a whole. The semi-cylindrical protrusion at the bottom of the inner wall of the socket handle matches the groove for placing the wire to achieve radial positioning. The semi-cylindrical protrusion in the middle of the inner wall of the socket handle makes elastic contact with the outer surface of the socket electrode to achieve axial displacement of the socket electrode. The trapezoidal annular protrusion on the outer circumference of the socket electrode skeleton engages with the trapezoidal annular groove on the inner wall of the socket handle to achieve axial positioning.
