Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of new energy power transmission, and particularly relates to a new energy high-voltage connector, a plug for the high-voltage connector, and a socket for the high-voltage connector. BACKGROUND

[0002] With the rapid development of new energy industries such as new energy vehicles and energy storage power stations, the safety, stability, anti-interference, and convenience of high-voltage connectors as core power transmission components directly affect the operation reliability of the entire new energy system. There are still many technical pain points in the actual application of existing new energy high-voltage connectors. First, the conductive contact part of the socket is exposed in the uninserted state, which is easy to cause electric shock accidents due to accidental contact by personnel, and the safety is insufficient. Second, there is a lack of effective anti-misplug mechanism during the insertion process, and in the installation scene with dim light or narrow space, the positive and negative poles are easy to be connected in reverse or the direction is easy to be misaligned, which may cause short circuit, equipment damage, and other serious consequences. Third, the connection firmness of the plug and the socket is poor, and under the working conditions such as driving bumping of new energy vehicles and vibration of energy storage equipment, the plug and the socket are easy to loosen, which may cause poor contact, increased resistance, and even electric arc to cause safety hazards. Fourth, the insulation structure design of the existing connector is unreasonable, and air gaps are easy to be left between the conductive part and the insulation wall, which affects the insulation performance and may cause insulation breakdown risk in high-voltage transmission scenarios. Fifth, the heat generated during high-voltage transmission is difficult to dissipate quickly, and long-term high-temperature operation may accelerate the aging of the components and reduce the service life of the connector.

[0003] To solve the above problems, some improvement schemes exist in the prior art, such as setting a shielding assembly on the connector to improve the anti-interference, or enhancing the connection stability through a simple buckle structure, but none of them can fully solve the core requirements of anti-touch protection, anti-misplug, firm connection, insulation sealing, and efficient heat dissipation. For example, a high-voltage connector and a high-voltage connector plug are disclosed in Chinese Patent No. CN212462240U, which improves the signal transmission quality through the cooperation of the shielding sheet and the shielding ring, but does not involve the design of anti-touch and anti-misplug structures. Chinese Patent No. CN117039756B discloses a new energy vehicle double-line side-by-side high-voltage connector, which realizes limiting and anti-rotation through the cooperation of the protruding blocks, but there is still room for improvement in the insulation sealing and heat dissipation performance. Therefore, there is an urgent need for a new energy high-voltage connector that integrates anti-touch, anti-misplug, firm connection, efficient insulation sealing, and heat dissipation functions to meet the high-performance requirements of high-voltage transmission components in the new energy industry. SUMMARY

[0004] The purpose of this invention is to overcome the shortcomings of existing high-voltage connectors for new energy, such as high risk of accidental contact, easy mis-insertion, weak connection, poor insulation and sealing performance, and poor heat dissipation. This invention provides a new energy high-voltage connector and a plug and socket for use with the high-voltage connector. Through an integrated structural design, this connector achieves multiple functions including preventing accidental contact, preventing mis-insertion, secure locking, efficient insulation and sealing, and rapid heat dissipation, thereby improving the safety, stability, and reliability of high-voltage transmission and extending its service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A new energy high-voltage connector includes a plug and a socket that are mutually compatible. When the plug and socket are inserted, they form a high-voltage conductive channel. The plug includes a plug housing, a plug conductive component disposed inside the plug housing, and a locking trigger component. The socket includes a socket housing, a socket conductive component disposed inside the socket housing, an anti-accidental contact component, and an anti-misinsertion positioning component. The plug conductive component and the socket conductive component are correspondingly adapted. The locking trigger component cooperates with the socket housing to securely lock the plug and socket. The anti-accidental contact component is used to block the socket conductive component in the un-inserted state. The anti-misinsertion positioning component is used to guide the plug and socket to accurately align and insert.

[0007] Furthermore, the plug housing has a hollow structure, with a mating end at one end and a cable inlet end at the other end; the plug conductive assembly includes at least two plug conductive terminals, which are arranged along the axial direction of the plug housing, with one end extending to the outside of the mating end to form a plug mating portion, and the other end electrically connected to a high-voltage cable through a cable fixing component; the outer side of the mating end of the plug housing is provided with an annular groove, and the locking trigger assembly is disposed in the annular groove.

[0008] The locking trigger assembly includes at least two elastic locking elements symmetrically arranged within an annular groove. Each elastic locking element includes a locking block and a return spring. One end of the return spring is fixedly connected to the bottom of the annular groove, and the other end is connected to the locking block. The outer side of the locking block is provided with a guide slope, and the inner side is provided with a locking protrusion. In its natural state, part of the structure of the locking block protrudes outside the annular groove.

[0009] Furthermore, the socket housing has a hollow structure, with a mating cavity at one end adapted to the plug insertion end and a cable lead-out end at the other end; the socket conductive assembly includes at least two socket conductive terminals, which are arranged along the axial direction of the socket housing, with one end extending into the mating cavity to form a socket mating cavity adapted to the plug mating part, and the other end electrically connected to a high-voltage cable through a cable fixing component; the inner sidewall of the mating cavity is provided with a locking groove adapted to the locking protrusion, and the locking groove is arranged along the circumference of the socket housing.

[0010] The anti-accidental contact component is located at the opening end of the docking cavity and includes an anti-touch plate and a linkage push rod. The anti-touch plate is rotatably connected to the inner wall of the docking cavity via a rotating shaft. The number of anti-touch plates is the same as the number of conductive terminals of the socket, and each anti-touch plate corresponds to blocking the opening of the socket docking cavity. One end of the linkage push rod is fixedly connected to the anti-touch plate, and the other end extends to the inner side of the docking cavity. An anti-touch reset spring is sleeved on the linkage push rod. In the natural state of the anti-touch reset spring, the anti-touch plate is in a horizontal blocking state, completely covering the opening of the socket docking cavity.

[0011] Furthermore, the anti-misinsertion positioning component includes a positioning boss disposed on the plug's mating end and a positioning groove disposed on the socket's mating cavity opening end. The positioning boss and the positioning groove are adapted in shape and can only cooperate in one direction. The cross-sectional shape of the positioning boss is an asymmetrical polygon, and the cross-sectional shape of the positioning groove matches the positioning boss. A guide strip is also provided on the outer side of the plug's mating end, and a guide groove adapted to the guide strip is provided on the inner sidewall of the mating cavity. The guide strip and the guide groove cooperate to achieve axial guidance of the plug and socket.

[0012] Furthermore, the socket housing's mating cavity is also equipped with an insulating sealing assembly, which includes an insulating bushing and a dielectric grease reservoir. The insulating bushing is fitted over the outer side of the socket's conductive terminals and fits tightly against the inner wall of the mating cavity. The dielectric grease reservoir is located between the insulating bushing and the socket's conductive terminals and is filled with dielectric grease. The insulating bushing has multiple oil outlet holes, which connect the dielectric grease reservoir to the socket's mating cavity. When the plug and socket are inserted, the plug's mating portion squeezes the dielectric grease reservoir, causing the dielectric grease to overflow through the oil outlet holes and fill the gap between the plug's mating portion and the socket's mating cavity, eliminating the air gap.

[0013] Furthermore, both the plug housing and the socket housing are provided with heat dissipation channels inside, which are arranged along the axial direction of the housing and communicate with the external environment; both the plug conductive component and the socket conductive component are fitted with heat dissipation sleeves on their outer sides, which are made of metal material with high thermal conductivity, and have multiple heat dissipation fins on their outer sides, which extend into the heat dissipation channels; both ends of the heat dissipation channels are provided with dustproof nets to prevent dust from entering.

[0014] Furthermore, both the plug housing and the socket housing are provided with a shielding layer on their outer side. The shielding layer is made of conductive metal braided mesh. One end of the shielding layer is electrically connected to the shielding layer of the high-voltage cable, and the other end is grounded through a grounding terminal to achieve electromagnetic shielding.

[0015] The present invention also provides a plug for a high-voltage connector for new energy, comprising a plug housing, a plug conductive component, and a locking trigger component; the plug housing is a hollow structure, with a mating end at one end and a cable entry end at the other end; the plug conductive component is disposed inside the plug housing and includes at least two plug conductive terminals, one end of which extends to the outside of the mating end to form a plug mating portion, and the other end is used for electrical connection with a high-voltage cable; the locking trigger component is disposed outside the mating end of the plug housing and includes an elastic locking member, which is used to cooperate with the socket housing to achieve locking.

[0016] The present invention also provides a socket for a high-voltage connector for new energy, comprising a socket housing, a socket conductive component, an anti-misoperation component, and an anti-misinsertion positioning component; the socket housing is a hollow structure, with a mating cavity at one end and a cable lead-out end at the other end; the socket conductive component is disposed inside the socket housing and includes at least two socket conductive terminals, one end of which extends into the mating cavity to form a socket mating cavity; the anti-misoperation component is disposed at the open end of the mating cavity to block the socket mating cavity in the un-molded state; the anti-misinsertion positioning component is disposed at the open end of the mating cavity to guide the plug to accurately align and insert.

[0017] In summary, the beneficial technical effects of the present invention are as follows:

[0018] 1. Excellent anti-accidental contact performance: By setting up an anti-accidental contact component, the anti-contact plate can completely block the contact end of the conductive component of the socket when it is not plugged in, effectively avoiding electric shock accidents caused by accidental contact; it automatically opens when plugged in, without affecting normal connection. The ingenious structural design greatly improves safety.

[0019] 2. Reliable anti-misinsertion effect: The positioning boss and positioning groove with an asymmetrical structure are used to achieve a unique direction of insertion, which fundamentally avoids the problems of incorrect insertion such as reversed positive and negative terminals or misalignment. At the same time, the guide strip and guide groove work together to improve the accuracy and convenience of insertion, making it suitable for installation scenarios with low light and small space.

[0020] 3. Secure and stable connection: Through the cooperation of the locking trigger component and the locking slot, the plug and socket automatically lock after being inserted into place. The locking structure is stable and can effectively resist the influence of external forces such as vibration and bumps, prevent the connection from loosening, and ensure the continuity and stability of high voltage transmission.

[0021] 4. Excellent insulation and sealing performance: An insulation and sealing component is set up, and the gap between the conductive part and the insulating wall is filled with dielectric grease to eliminate air gaps, avoid the risk of insulation breakdown in high-voltage scenarios, and at the same time improve the waterproof and dustproof performance of the connector, making it suitable for complex working environments.

[0022] 5. High heat dissipation efficiency: Through the combination of heat dissipation sleeves, heat dissipation fins and heat dissipation channels, the heat generated during high voltage transmission can be quickly dissipated, reducing the operating temperature of components, slowing down the aging process and extending the service life of connectors.

[0023] 6. Strong anti-interference capability: The outer shell is equipped with a shielding layer, which can effectively block external electromagnetic interference and conduct internal electromagnetic radiation to the ground, ensuring the stability of high voltage transmission and making it suitable for complex electromagnetic environments such as new energy vehicles and energy storage power stations.

[0034] In this embodiment, both the plug housing 3 and the socket housing 6 are made of high-temperature and high-pressure resistant insulating materials, specifically polyetheretherketone (PEEK). This material has excellent insulation properties, mechanical strength, and high-temperature resistance, and can be adapted to the working environment of high-voltage transmission of new energy. Both the plug conductive component 4 and the socket conductive component 7 are made of copper with silver plating on the surface to reduce contact resistance and improve conductivity and oxidation resistance.

[0035] The plug housing 3 has a hollow structure, with a mating end 10 at one end and a cable entry end 11 at the other end. The plug conductive assembly 4 includes two plug conductive terminals 12, corresponding to the positive and negative poles respectively. The plug conductive terminals 12 are arranged along the axial direction of the plug housing 3, with one end extending to the outside of the mating end 10 to form a plug mating part 13. The plug mating part 13 has a cylindrical cross-section and an annular protrusion on the outside to enhance the contact stability with the socket mating cavity 23. The other end is electrically connected to the high-voltage cable through the cable fixing member 14. The cable fixing member 14 adopts a compression structure to ensure that the high-voltage cable is firmly connected to the plug conductive terminal 12 and to avoid poor contact.

[0036] The plug housing 3 has an annular groove 15 on the outer side of the mating end 10, and the locking trigger assembly 5 is disposed in the annular groove 15. The locking trigger assembly 5 includes two elastic locking members, which are symmetrically arranged in the annular groove 15. The elastic locking members include a locking block 16 and a return spring 17. One end of the return spring 17 is fixedly connected to the bottom of the annular groove 15, and the other end is connected to the locking block 16. The outer side of the locking block 16 is provided with a guide slope 18, and the inner side is provided with a locking protrusion 19. In the natural state, part of the structure of the locking block 16 protrudes outside the annular groove 15, which facilitates its cooperation with the locking slot 24 of the socket housing 6.

[0037] The socket housing 6 has a hollow structure. One end of the housing is provided with a mating cavity 20 that is adapted to the plug mating end 10, and the other end is provided with a cable lead-out end 21. The socket conductive component 7 includes two socket conductive terminals 22, which correspond to the positive and negative poles respectively. The socket conductive terminals 22 are arranged along the axial direction of the socket housing 6. One end of the terminals extends into the interior of the mating cavity 20 to form a socket mating cavity 23 that is adapted to the plug mating part 13. The inner side wall of the socket mating cavity 23 is provided with an annular groove that is adapted to the annular protrusion on the outer side of the plug mating part 13 to improve contact stability. The other end is electrically connected to the high-voltage cable through the cable fixing member 14. The structure of the cable fixing member 14 is the same as that of the plug side.

[0038] The inner wall of the docking cavity 20 is provided with a locking groove 24 that matches the locking protrusion 19. The locking groove 24 is arranged around the circumference of the socket housing 6. The cross-sectional shape of the locking groove 24 is arc-shaped, matching the shape of the locking protrusion 19, to ensure that it is not easy to fall off after locking. The anti-accidental contact component 8 is provided at the opening end of the docking cavity 20, including an anti-touch plate 25 and a linkage push rod 26. The anti-touch plate 25 is rotatably connected to the inner wall of the docking cavity 20 through a rotating shaft 27. There are two anti-touch plates 25, which respectively block the openings of the two socket docking cavities 23. The size of the anti-touch plate 25 matches the opening size of the socket docking cavity 23 to ensure complete blockage. One end of the linkage push rod 26 is fixedly connected to the anti-touch plate 25, and the other end extends to the inner side of the docking cavity 20. An anti-touch reset spring 28 is sleeved on the linkage push rod 26. In the natural state of the anti-touch reset spring 28, the anti-touch plate 25 is in a horizontal blocking state, completely covering the opening of the socket docking cavity 23 to prevent accidental contact by personnel.

[0039] The anti-misinsertion positioning component 9 includes a positioning boss 29 disposed on the plug mating end 10 and a positioning groove 30 disposed on the opening end of the socket mating cavity 20. The positioning boss 29 has an L-shaped cross-section, and the positioning groove 30 matches the positioning boss 29 in cross-section and can only cooperate in one direction, fundamentally preventing the positive and negative terminals from being reversed. Two guide strips 31 are also provided on the outer side of the plug mating end 10 of the plug housing 3, symmetrically arranged on both sides of the positioning boss 29. The inner sidewall of the mating cavity 20 is provided with a guide groove 32 adapted to the guide strips 31. The guide strips 31 and the guide groove 32 cooperate to realize the axial guidance of the plug 1 and the socket 2, ensuring a smooth mating process.

[0040] The socket housing 6 also has an insulating sealing assembly 33 inside the mating cavity 20. The insulating sealing assembly 33 includes an insulating bushing 34 and a dielectric grease storage section 35. The insulating bushing 34 is fitted on the outside of the socket conductive terminal 22 and is tightly fitted to the inner wall of the mating cavity 20. The insulating bushing 34 is made of silicone rubber and has excellent insulation and sealing performance. The dielectric grease storage section 35 is located between the insulating bushing 34 and the socket conductive terminal 22. The dielectric grease storage section 35 is filled with dielectric grease, which has excellent insulation and thermal conductivity. The insulating bushing 34 has multiple oil outlet holes 36, which connect the dielectric grease storage section 35 and the socket mating cavity 23. When the plug 1 and the socket 2 are plugged in, the plug mating part 13 squeezes the dielectric grease storage section 35, causing the dielectric grease to overflow through the oil outlet holes 36 and fill the gap between the plug mating part 13 and the socket mating cavity 23, eliminating air gaps and improving insulation and sealing performance.

[0041] Both the plug housing 3 and the socket housing 6 have internal heat dissipation channels 37, which are arranged along the axial direction of the housing and are connected to the external environment. Both the plug conductive component 4 and the socket conductive component 7 are fitted with heat dissipation sleeves 38. The heat dissipation sleeves 38 are made of copper alloy and have a high thermal conductivity. Multiple heat dissipation fins 39 are provided on the outside of the heat dissipation sleeves 38, which extend into the heat dissipation channels 37 to increase the heat dissipation area. Both ends of the heat dissipation channels 37 are provided with dustproof nets 40 to prevent dust from entering and affecting the heat dissipation effect.

[0042] Both the plug housing 3 and the socket housing 6 are provided with a shielding layer 41 on their outer sides. The shielding layer 41 is made of copper wire braided mesh. One end of the shielding layer 41 is electrically connected to the shielding layer of the high-voltage cable, and the other end is grounded through the grounding terminal 42 to achieve electromagnetic shielding, effectively blocking external electromagnetic interference, and at the same time, conducting internal electromagnetic radiation to ground to ensure the stability of high-voltage transmission.

[0043] This embodiment also provides a plug for a new energy high-voltage connector, including a plug housing 3, a plug conductive component 4, and a locking trigger component 5; the plug housing 3 has a hollow structure, with a mating end 10 at one end and a cable entry end 11 at the other end; the plug conductive component 4 is disposed inside the plug housing 3, including two plug conductive terminals 12, one end of which extends to the outside of the mating end 10 to form a plug mating portion 13, and the other end is used for electrical connection with a high-voltage cable; the locking trigger component 5 is disposed outside the mating end 10 of the plug housing 3, including two symmetrically arranged elastic locking members, which are used to cooperate with the socket housing 6 to achieve locking.

[0044] This embodiment also provides a socket for a new energy high-voltage connector, including a socket housing 6, a socket conductive component 7, an anti-misoperation component 8, and an anti-misinsertion positioning component 9; the socket housing 6 has a hollow structure, with a mating cavity 20 at one end and a cable lead-out end 21 at the other end; the socket conductive component 7 is disposed inside the socket housing 6, including two socket conductive terminals 22, one end of which extends into the mating cavity 20 to form a socket mating cavity 23; the anti-misoperation component 8 is disposed at the open end of the mating cavity 20 to block the socket mating cavity 23 in the un-inserted state; the anti-misinsertion positioning component 9 is disposed at the open end of the mating cavity 20 to guide the plug 1 to be accurately aligned and inserted.

[0045] When the new energy high voltage connector of the present invention is used, the plug and socket are first precisely aligned by the anti-misinsertion positioning component: the positioning boss at the plug insertion end cooperates with the positioning groove at the opening end of the socket mating cavity, and can only be inserted in one direction to avoid reversed positive and negative terminals or misalignment; at the same time, the guide strip cooperates with the guide groove to achieve axial guidance of the plug and socket, ensuring smooth insertion process.

[0046] During the insertion process, the plug mating part first contacts the linkage push rod of the anti-accidental contact component, pushing the anti-touch plate to rotate around the pivot. The anti-touch reset spring is compressed, and the anti-touch plate gradually opens, releasing the obstruction of the socket mating cavity. As the plug is continuously inserted, the plug mating part is inserted into the socket mating cavity, realizing electrical connection. At the same time, the elastic locking member on the outside of the plug is squeezed under the action of the guide slope, the reset spring contracts, and the locking block retracts into the annular groove. When the plug is fully inserted, the locking block pops out under the action of the reset spring, and the locking protrusion engages in the locking groove on the inside of the socket mating cavity, realizing a firm lock between the plug and the socket and preventing loosening due to vibration.

[0047] After the plug is fully engaged, the plug mating part squeezes the dielectric grease reservoir, causing the dielectric grease to overflow through the oil outlet and fill the gap between the plug mating part and the socket mating cavity. This eliminates the air gap between the conductive part and the insulating wall, improving the insulation and sealing performance. During high-voltage transmission, the heat generated is conducted to the heat dissipation fins through the heat dissipation sleeve. The heat dissipation fins exchange heat with the air in the heat dissipation channel, achieving rapid heat dissipation. The shielding layer can effectively block external electromagnetic interference and conduct internal electromagnetic radiation to ground, ensuring the stability of high-voltage transmission.

[0048] When disconnection is required, press the locking block of the elastic locking element to disengage the locking protrusion from the locking slot, and at the same time pull the plug outward. The anti-touch plate will reset under the action of the anti-touch reset spring, and re-cover the opening of the socket mating cavity to prevent personnel from accidentally touching the conductive parts and improve the safety of use.

[0049] The new energy high-voltage connector of the present invention can be widely adapted to high-voltage connections between battery packs and motors / controllers in new energy vehicles, and high-voltage connections between battery modules in energy storage power stations, etc. It can effectively improve the safety, stability and reliability of high-voltage transmission and has broad application prospects.
