Description

Technical Field

[0001] This application relates to the technical field of high-voltage connectors, and more particularly to a high-voltage connector. Background Technology

[0002] With the rapid development of electric vehicles, renewable energy systems, and industrial equipment, high-voltage connectors, as core components for power transmission, are facing increasingly stringent performance requirements. Because high-voltage connectors generate strong electromagnetic interference (EMI) during operation, without effective shielding measures, they may cause signal interference or even malfunctions in surrounding electronic equipment. Therefore, current technologies commonly employ metal shielding components (such as braided layers or metal shells) to encase the internal conductors of the connector to achieve electromagnetic shielding.

[0003] However, conventional shielding installation structures have significant drawbacks: on the one hand, the fit between the shielding component and the connector housing or insulator is mostly mechanical crimping or welding, lacking a reliable sealing design. This makes it easy for gas or liquid permeation channels to form between the connector's interior and the external environment, resulting in poor airtightness. On the other hand, external moisture, dust, and other contaminants may penetrate the connector's interior through gaps between the shielding component and the housing, accelerating the aging or corrosion of internal components and reducing electrical performance and long-term reliability. Furthermore, insufficient airtightness may also weaken the electromagnetic shielding effectiveness of the shielding component, creating a vicious cycle. Utility Model Content

[0004] The purpose of this application is to provide a high-voltage connector, in which a first sealing element surrounds a bent portion on the end face of the socket housing, thereby forming a more perfect seal on the shielding element and effectively ensuring that the airtightness of the socket assembly will not leak from the shielding element when used alone.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On one hand, a high-voltage connector is provided, comprising: a socket assembly and a plug assembly that is inserted into the socket assembly in a insertion / removal direction. The socket assembly includes: a socket housing, socket terminals, a shield, and a first sealing member. The socket terminals are inserted into the socket housing, and a first through hole is provided on the socket housing. The shield includes a bent portion and a shielding portion. The bent portion is locked to the end face of the socket housing through the first through hole, such that the shielding portion surrounds the socket terminals. The shield is fitted into the end face of the socket housing and surrounds the outer periphery of the bent portion.

[0007] Furthermore, the other end of the socket housing is provided with a guide baffle surrounding the outer periphery of the shielding part. The plug assembly includes a plug housing and a second sealing member. The plug housing is guided and engaged with the guide baffle to be inserted into the socket housing. The second sealing member is disposed between the guide baffle and the plug housing to form a sealing structure.

[0008] Furthermore, the inner side of the guide baffle is provided with a sealing protrusion that abuts against the second sealing element.

[0009] Furthermore, the outer side of the guide baffle is provided with a plurality of guide strips at intervals, and the plug housing is provided with guide grooves that cooperate with the guide strips.

[0010] Furthermore, the socket housing is provided with a first protrusion, and the first protrusion is provided with a locking hole. The plug housing is provided with a second protrusion corresponding to the first protrusion, and the second protrusion is provided with a second through hole corresponding to the locking hole. After the plug housing is inserted into the socket housing, the fastener passes through the second through hole and locks itself in the locking hole.

[0011] Furthermore, the plug assembly also includes an end cap, which is installed at the opening of the plug housing to lock the second seal inside the plug housing.

[0012] Furthermore, the socket assembly also includes a wire harness assembly that is locked onto the socket housing by an interlocking structure, and the end cap is integrally formed with a PIN pin that mates with the wire harness assembly, and a retaining member is provided around the PIN pin.

[0013] Furthermore, the inner side of the plug housing is provided with a plurality of gap ribs that contact the outer wall of the guide baffle.

[0014] Furthermore, the outer side of the plug housing is provided with an auxiliary protrusion for assisting insertion and removal.

[0015] Furthermore, the socket terminals are integrally molded onto the socket housing via injection molding.

[0016] The beneficial effects of this application are as follows: the integrated design of the bend locking and the sealing element significantly improves the performance of the high-voltage connector. First, the circumferential sealing of the bend by the first sealing element solves the problem of poor airtightness after installation of traditional shielding elements. When the socket is used alone, it can effectively prevent the intrusion of external contaminants and the leakage of internal media, ensuring long-term reliability under independent operating conditions. Second, the bend serves as both a fixing structure for the shielding element and a sealing interface in conjunction with the first sealing element, achieving a high degree of integration of electromagnetic shielding and sealing functions. This simplifies the complex process of the split sealing structure in traditional solutions, reduces costs, and makes assembly easier. Attached Figure Description

[0025] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] like Figures 1 to 6 As shown, this embodiment provides a high-voltage connector, including: a socket assembly 1 and a plug assembly 2 that is inserted into and removed from the socket assembly 1 in the insertion / removal direction. The socket assembly 1 includes: a socket housing 101, a socket terminal 102, a shield 103, and a first sealing member 104. The socket terminal 102 is inserted into the socket housing 101. The socket housing 101 has a first through hole. The shield 103 includes a bent portion 1031 and a shield 1032. The bent portion 1031 is locked to the end face of the socket housing 101 through the first through hole, so that the shield 1032 surrounds the socket terminal 102. The shield 103 is fitted into the end face of the socket housing 101 and surrounds the outer periphery of the bent portion 1031.

[0029] The high-voltage connector in this application embodiment achieves synergistic optimization of electromagnetic shielding and airtight sealing through structural innovation. Specifically, the end face of the socket housing 101 is provided with a first through hole. The bent portion 1031 of the shielding member 103 (e.g., a metal sheet bent at a right angle or arc) passes through the first through hole and is locked to the end face. It is fixed by mechanical snap-fit, threaded fastening, or crimping process to ensure that the shielding portion 1032 (such as a metal shielding cover or braided layer) completely covers the socket terminal 102, forming a continuous electromagnetic shielding layer and blocking the leakage of internal high-frequency electromagnetic fields. At the same time, the first sealing member 104 (such as an annular sealing ring made of silicone or fluororubber) is fitted into the annular groove on the end face of the socket housing 101 in an interference fit manner and tightly wraps the outer peripheral surface of the bent portion 1031. When the socket assembly 1 is used alone, the elastic body of the first seal 104 is compressed by the bending part 1031 and undergoes radial deformation, filling the tiny gaps formed by the electroplating layer or machining tolerance, while forming an axial sealing surface on the end face, completely blocking external moisture and dust from entering the interior through the assembly gap between the shield 103 and the housing, or preventing internal insulating gas / liquid from leaking out.

[0030] This solution achieves a dual breakthrough in electromagnetic shielding and hermetic sealing performance of high-voltage connectors through the coordinated design of the bent portion 1031 of the shielding component 103 and the first sealing component 104. Its core advantage lies in the fact that the first sealing component 104 directly wraps around the bent portion 1031 of the shielding component 103, forming a full-circumferential seal on the assembly gap of the shielding component 103 when the socket is used alone. This completely prevents gas or contaminants from leaking through the interface between the shielding component 103 and the outer shell, overcoming the inherent defect of traditional solutions that rely on passive sealing after plug insertion. Simultaneously, the design of the bent portion 1031 locking to the end face of the socket outer shell 101 through the first through hole not only ensures a stable connection between the shielding component 103 and the outer shell to maintain electromagnetic shielding effectiveness, but also creates an adaptive sealing interface through the elastic compression deformation of the first sealing component 104. This effectively compensates for gap changes caused by machining tolerances or vibration, significantly improving long-term sealing reliability. Furthermore, this structure eliminates the complex processes required for traditional split-type seals (such as potting or independent sealing flanges), significantly simplifying the assembly process and reducing manufacturing costs through integrated design, while also being compatible with the expansion needs of different terminal specifications. Utilizing special elastomer materials that are resistant to high temperatures and chemical corrosion, the connector's stability is further enhanced in extreme temperature, humidity, or polluted environments. It can be widely used in fields with stringent requirements for airtightness and electromagnetic compatibility, such as new energy vehicles, industrial equipment, and energy storage systems, providing a highly reliable and environmentally adaptable solution for high-voltage power transmission.

[0031] Furthermore, the other end of the socket housing 101 is provided with a guide baffle 1011 surrounding the outer periphery of the shielding portion 1032. The plug assembly 2 includes a plug housing 201 and a second sealing member 202. The plug housing 201 is inserted into the socket housing 101 in a guiding fit with the guide baffle 1011. The second sealing member 202 is disposed between the guide baffle 1011 and the plug housing 201 to form a sealing structure. The guide baffle 1011 protruding from the other end of the socket housing 101 surrounds the outer periphery of the shielding portion 1032, and its inner wall is provided with a guiding surface, forming a physical guiding fit with the corresponding structure on the outer periphery of the plug housing 201. When the plug assembly 2 is inserted into the socket in the insertion / removal direction, the plug housing 201 contacts and slides against the guide surface of the guide baffle 1011, forcing the plug housing 201 to automatically correct its coaxiality with the socket housing 101, thus preventing terminal misalignment or deformation of the shield 103 due to angular deviation. Simultaneously, the outward expansion structure of the guide baffle 1011 mechanically limits the insertion depth of the plug housing 201, ensuring precise pressing between the plug housing 201 and the end face of the socket housing 101. During this process, the guide baffle 1011 also acts as a physical barrier, preventing external foreign objects from directly colliding with the shield 1032 or the socket terminal 102, reducing the risk of mechanical damage during insertion and removal.

[0032] Simultaneously, the second sealing element 202 (such as an O-ring or a shaped sealing ring) is pre-installed inside the plug housing 201. When the plug housing 201 is inserted into place, the second sealing element 202 is subjected to radial compression by the side wall of the guide baffle 1011 and the outer wall of the plug housing 201, resulting in elastic deformation to fill the assembly gap between them and form a radial sealing interface. This sealing interface, together with the first sealing element 104 at the socket end, constitutes a "double sealing layer": the first sealing element 104 blocks the leakage path between the shield 103 and the socket housing 101, while the second sealing element 202 isolates the external environment from the communication channel between the plug and socket mating surfaces. The combined effect of the two can effectively prevent high-pressure water jets, oil mist, or dust from entering the connector from the insertion direction. In addition, the elastic restoring force of the second sealing element 202 provides a retaining force for the plug housing 201, preventing the plug from accidentally loosening due to vibration or external pulling.

[0033] Furthermore, the inner side of the guide baffle 1011 is provided with a sealing protrusion 1012 that abuts against the second sealing member 202. The sealing protrusion 1012 on the inner side of the guide baffle 1011 protrudes relative to the inner wall, forming a stepped sealing interface. During the insertion process of the plug housing 201, the second sealing member 202 (such as a shaped sealing ring) pre-installed on the plug housing 201 first contacts the smooth area of ​​the inner wall of the guide baffle 1011. Since the contact surface between the inner wall and the second sealing member 202 is a continuous and smooth surface, and the sealing protrusion 1012 has not intervened, the second sealing member 202 is only subjected to slight radial compression at this time, and the friction is small. The plug housing 201 can easily slide into the guide baffle 1011, avoiding jamming or wear caused by premature over-compression of the second sealing member 202. When the plug housing 201 is inserted into place, the second seal 202 continues to move with the plug housing 201 until it aligns with the sealing protrusion 1012. At this point, the sealing protrusion 1012 applies additional radial compressive force to the second seal 202, forcing it to further deform and tightly fill the gap between the guide baffle 1011 and the plug housing 201, forming a high-pressure sealing interface. This staged contact mechanism ensures both the smoothness of the insertion process and the concentration of the final sealing pressure at the precise position after insertion.

[0034] The stepped structure of the sealing protrusion 1012, combined with a phased contact mechanism, significantly optimizes sealing performance and the insertion experience. Firstly, the low-friction contact between the second seal 202 and the smooth inner wall during the initial insertion phase reduces insertion and extraction forces (especially suitable for large-size or multi-core connectors), avoiding the sharp increase in resistance caused by the friction between the second seal 202 and the protrusion structure throughout the entire process, as is common in traditional solutions, thus improving the smoothness of manual or robotic arm insertion and extraction operations. Secondly, once in place, the directional pressure applied by the sealing protrusion 1012 to the second seal 202 increases the local compression at the sealing interface, forming a stronger sealing barrier that effectively resists external high-pressure water jets or aerosol penetration. Thirdly, the phased compression avoids excessive deformation of the second seal 202 throughout the insertion process, reducing material fatigue damage and extending the service life of the second seal 202. Simultaneously, the limiting effect of the sealing protrusion 1012 on the second seal 202 prevents creep displacement due to vibration during use, ensuring long-term sealing stability. This design balances lightweight plug-in design with high sealing reliability, making it particularly suitable for scenarios requiring frequent plugging and unplugging or stringent sealing requirements (such as charging pile interfaces and underwater equipment connectors).

[0035] Furthermore, the outer side of the guide baffle 1011 is provided with a plurality of guide strips 1015 spaced apart, and the plug housing 201 is provided with a guide groove 2011 that guides and cooperates with the guide strips 1015. The plurality of guide strips 1015 spaced apart on the outer side of the guide baffle 1011 (such as 3-6 raised ridges evenly distributed along the circumference) and the corresponding guide grooves 2011 (such as grooves or slide rails) in the plug housing 201 form a staged guiding mechanism. When the plug assembly 2 is initially inserted, the inclined front end of the guide strip 1015 contacts the flared structure at the entrance of the guide groove 2011, guiding the plug housing 201 to quickly center, and allowing adaptive correction of small angular deviations through the width difference between the guide strip 1015 and the guide groove 2011; as the plug continues to be inserted, the guide strip 1015 gradually embeds into the straight section of the guide groove 2011, forcibly restricting the radial displacement and circumferential rotation between the plug housing 201 and the socket housing 101, ensuring precise coaxial alignment of the plug terminals and the socket terminals 102. Meanwhile, the spacing design of the guide bar 1015 creates a chip removal channel during insertion and removal, allowing external foreign objects (such as sand and debris) to be discharged from the gaps and preventing jamming. When the plug is fully inserted, the end of the guide bar 1015 contacts the limiting surface at the bottom of the guide groove 2011, providing clear insertion feedback.

[0036] Optionally, the socket housing 101 is provided with a first boss 1013, and the first boss 1013 is provided with a locking hole 1014. The plug housing 201 is provided with a second boss 2012 corresponding to the first boss 1013, and the second boss 2012 is provided with a second through hole corresponding to the locking hole 1014. After the plug housing 201 is inserted into the socket housing 101, the fastener 3 passes through the second through hole and locks itself in the locking hole 1014. The first boss 1013 (such as a square or cylindrical protrusion) on the socket housing 101 is provided with a locking hole 1014 (such as a threaded hole), and the second boss 2012 (whose shape matches that of the first boss 1013) on the plug housing 201 is provided with a coaxial second through hole. When the plug housing 201 is fully inserted into the socket housing 101, the end faces of the first boss 1013 and the second boss 2012 are fitted together, and the second through hole aligns with the locking hole 1014. A fastener 3 (such as a bolt, screw, or pin) passes through the second through hole and locks into the locking hole 1014, achieving a rigid connection between the plug and the socket. During this process, the mating surfaces of the first boss 1013 and the second boss 2012 also act as radial limiters, suppressing lateral displacement of the plug housing 201. Simultaneously, the preload of the fastener 3 presses the plug housing 201 tightly against the end face of the socket housing 101, further compressing the first seal 104 and the second seal 202, ensuring uniform pressure distribution at the sealing interface. This design allows for flexible selection of manual or tool-based locking after insertion, adapting to different installation scenarios.

[0037] In some embodiments, the plug assembly 2 further includes an end cap 203, which is installed at the opening of the plug housing 201 to lock the second seal 202 within the plug housing 201. The end cap 203 (such as an annular cap made of metal or engineering plastic) is installed at the opening end of the plug housing 201 by threaded connection, snap-fit, or interference fit. During assembly, the second seal 202 (such as a shaped sealing ring) is pre-placed in a pre-set annular groove within the plug housing 201. Subsequently, the end cap 203 is axially pressed into the opening, with its inner wall or end face contacting the non-compression side of the second seal 202. The radial limiting structure of the end cap 203 (such as an annular flange or barb) axially locks the second seal 202 within the plug housing 201, preventing displacement due to vibration or insertion / removal operations. Meanwhile, the installation depth of the end cap 203 can be adjusted to pre-tighten the second seal 202, ensuring that the second seal 202 remains under moderate compression when the plug is not in use, thus preventing material deformation or sealing interface failure due to long-term relaxation. When the plug housing 201 is inserted into the socket housing 101, the compression side of the second seal 202 is squeezed by the guide baffle 1011, while the end cap 203 acts as a rigid support to prevent the second seal 202 from collapsing in the opposite direction, maintaining the stability of the sealing pressure.

[0038] Meanwhile, the socket assembly 1 also includes a wire harness assembly 105 locked to the socket housing 101 by an interlocking structure. A PIN pin 204, which mates with the wire harness assembly 105, is integrally formed on the end cap 203. A retaining member 205 is provided around the PIN pin 204. The wire harness assembly 105 of the socket assembly 1 is fixed to the socket housing 101 by an interlocking structure (such as a snap-fit, dovetail groove, or threaded locking ring). Its internal conductor is electrically connected to the socket terminal 102 to achieve power or signal transmission. The PIN pin 204 integrally formed on the end cap 203 is combined with the end cap 203 base through injection molding or insert molding processes. The tail end of the PIN pin 204 extends into the plug housing 201 and is conductive to the plug terminal. When the end cap 203 is installed onto the plug housing 201, the head of the PIN pin 204 is precisely aligned with the interface of the wiring harness assembly 105. The retainer 205 surrounds the outer periphery of the PIN pin 204. During the plug-socket connection process, the retainer 205 is inserted first into the mating area of ​​the wiring harness assembly 105, physically isolating the PIN pin 204 from accidental contact with surrounding metal parts that could cause a short circuit. Simultaneously, it guides the PIN pin 204 to coaxially align with the wiring harness interface. After insertion, the end face of the retainer 205 presses against the sealing surface of the wiring harness assembly 105, forming an additional dustproof barrier.

[0039] Preferably, the inner side of the plug housing 201 is provided with a plurality of gap ribs that contact the outer wall of the guide baffle 1011. These gap ribs, such as 4-8 circumferentially distributed arc-shaped ribs, form localized point / line contacts with the outer wall of the guide baffle 1011, rather than traditional large-area surface contacts. During plug insertion, the arc-shaped convex surfaces of the gap ribs preferentially slide against the outer wall of the guide baffle 1011, significantly reducing frictional resistance by decreasing the effective contact area.

[0040] It is worth mentioning that the outer side of the plug housing 201 is provided with auxiliary protrusions 2013 for assisting insertion and removal. These auxiliary protrusions 2013, such as symmetrically distributed arc-shaped protrusions or strip-shaped ridges, provide a force fulcrum for manual or mechanical insertion and removal operations through optimized outer contour geometry and ergonomic design. During manual insertion and removal, the operator's fingers can grip the concave arc surface or anti-slip textured area of ​​the auxiliary protrusions 2013, converting the applied axial force into a smooth displacement of the plug housing 201, avoiding slippage or uneven force application caused by gripping a smooth housing. If mechanical gripper operation is used, the standardized contour of the auxiliary protrusions 2013 (such as cylindrical or rectangular protrusions) can match the universal clamps of automated equipment, ensuring accurate clamping and positioning, and reducing the risk of terminal misalignment due to off-center loading during insertion and removal. Furthermore, the height and spacing design of the auxiliary protrusions 2013 takes into account the overall dimensional constraints of the plug housing 201, ensuring that they protrude from the housing surface to provide effective gripping space without interfering with surrounding equipment or cables.

[0041] Furthermore, the socket terminal 102 is manufactured using a stamping process, and after forming, a nut is riveted. This stamped socket terminal 102 can be locked parallel to the thickness direction of the copper busbar. Then, the socket terminal 102 is integrally molded into the socket housing 101 by injection molding. The socket terminal 102 is made using a metal sheet stamping process. The terminal body with riveting holes is formed by precision punching and bending using a mold. Then, the nut is inserted into the riveting hole and fixed by hydraulic or cold riveting process, so that the nut and the terminal form a rigid connection in both the thickness direction and the parallel direction, which can adapt to the bolt locking requirements of copper busbars or cables of different thicknesses. The riveted terminal is integrally formed into the socket housing 101 by an insert injection molding process: the terminal is pre-placed in the injection mold cavity, and molten engineering plastic is injected into the mold to wrap the non-contact area of ​​the terminal. After curing, the terminal is precisely fixed in the socket housing 101, and the locking end of its nut is exposed on the surface of the housing, realizing the efficient integration of electrical connection interface and insulation structure. This process ensures a gapless connection between the terminals and the housing, while the plastic coating enhances the terminals' resistance to bending and vibration.
