[0022] In recent years, driven by global energy transition and environmental policies, the new energy vehicle industry has experienced explosive growth. As its core power system, the application of high-voltage, high-current platforms is becoming increasingly widespread to meet the demands of fast charging, high power output, and long driving range. Against this backdrop, the performance and reliability of high-voltage, high-current connectors directly affect the safety and lifespan of the entire vehicle.

[0023] Currently, the sealing performance of mainstream high-voltage connectors on the market is poor, which can easily lead to safety hazards.

[0024] In view of this, the present invention proposes a connector and a connecting assembly, which forms a waterproof groove by enclosing the first flange, the outer wall of the insulating core, and the socket housing. A waterproof sealing ring is set in the waterproof groove. By fitting the waterproof sealing ring onto the outer wall of the insulating core and limiting the waterproof sealing ring by the waterproof groove, the waterproof sealing ring is ensured to be tightly set in the waterproof groove. This not only prevents liquid from entering the socket housing from the gap between the insulating core and the socket housing, but also prevents the waterproof sealing ring from falling off or shifting during vibration, thereby improving the waterproof performance of the entire connector.

[0025] To better understand the above technical solution, a detailed explanation of the technical solution is provided below with reference to the accompanying drawings.

[0026] like Figure 1-13 As shown, this utility model proposes a connector 100, including a socket housing 10, an insulating core 20, and a terminal 30: the socket housing 10 is provided with at least one limiting hole 11; the insulating core 20 is partially installed in the limiting hole 11, the insulating core 20 is provided with a fixing hole 21, the insulating core 20 is provided with a first flange 22 in the radial direction, and a gap 100a is provided between the first flange 22 and the socket housing 10 in the axial direction; the terminal 30 is fixedly installed in the fixing hole 21; wherein, the first flange 22, the outer wall of the insulating core 20, and the socket housing 10 together form a waterproof groove 100b, and a waterproof sealing ring 40 is sleeved on the outer wall of the insulating core 20 so that the waterproof sealing ring 40 is confined within the waterproof groove 100b.

[0027] Understandably, by providing at least one limiting hole 11 within the socket housing 10, a foundation can be provided for the installation of the insulating core 20, facilitating its installation. One end of the insulating core 20 is installed in the limiting hole 11, and the other end extends out of the limiting hole 11 of the socket housing 10. By providing a fixing hole 21 within the insulating core 20, the terminal 30 can be installed and positioned, maintaining the connection stability of the terminal 30. The insulating core 20 has a first flange 22 arranged radially, and the first flange 22, the outer wall of the insulating core 20, and the socket housing 10 together form a waterproof groove 100b. Understandably, the first flange 22 is located at the end of the insulating core 20 that extends out of the limiting hole 11. The waterproof groove 100b is formed by the first flange 22, the outer wall of the insulating core 20, and the socket housing 10. This groove confines the waterproof sealing ring 40 within the waterproof groove 100b, ensuring that the waterproof sealing ring 40 is tightly fitted within it and preventing it from falling off or shifting during vibration. Furthermore, by fitting the waterproof sealing ring 40 onto the outer wall of the insulating core 20, the friction between the outer wall of the insulating core 20 and the waterproof sealing ring 40 further prevents it from falling off or shifting. On the other hand, since the waterproof sealing ring 40 is located within the waterproof groove 100b, which is formed by the first flange 22, the outer wall of the insulating core 20, and the socket housing 10, it effectively prevents liquids and stains from entering the socket housing 10 through the gap between the insulating core 20 and the socket housing 10, thus improving the overall waterproof performance of the connector 100.

[0028] Furthermore, in one embodiment of the present invention, the socket housing 10 is further provided with an assembly hole 12, the limiting hole 11 and the assembly hole 12 are coaxial and connected, and the assembly hole 12 is provided with a blocking member 50.

[0029] Understandably, the socket housing 10 has a limiting hole 11 at one end and an assembly hole 12 at the other end, with the limiting hole 11 and the assembly hole 12 communicating with each other. One end of the insulating core 20 is installed in the limiting hole 11, and the other end extends out of the limiting hole 11. The barrier 50 is disposed in the assembly hole 12. The barrier 50 can block external impurities and improve the overall performance of the connector 100.

[0030] Furthermore, in one embodiment of the present invention, the socket housing 10 is provided with a mounting groove 13 around the limiting hole 11 at one end away from the barrier member 50. The mounting groove 13 communicates with the limiting hole 11. The mounting groove 13 is provided with a second flange 14 around the limiting hole 11. The first flange 22 and the second flange 14 have the same height. The first flange 22, the outer wall of the insulating core 20, and the second flange 14 together form the waterproof groove 100b.

[0031] Understandably, by providing a mounting groove 13 on the socket housing 10, a tight connection between the mounting panel 80 and the socket housing 10 is facilitated. During installation, the mounting panel 80 can partially extend into the mounting groove 13 to ensure a tight connection between the mounting panel 80 and the mounting groove 13. By providing a second flange 14 around the limiting hole 11 in the mounting groove 13, a waterproof groove 100b can be formed using the first flange 22, the outer wall of the insulating core 20, and the second flange 14, thereby facilitating the installation and limiting of the waterproof sealing ring 40. Simultaneously, since the first flange 22 and the second flange 14 are of the same height, when the mounting panel 80 is connected to the socket housing 10, the structure of the mounting panel 80 itself can cover the opening of the waterproof groove 100b, further preventing water and stains from entering the interior of the socket housing 10 from between the socket housing 10 and the insulating core 20.

[0032] Furthermore, in one embodiment of the present invention, a first waterproof groove 11a is provided on the wall of the limiting hole 11, and a first sealing ring 60 is provided in the first waterproof groove 11a. The wall of the limiting hole 11 limits the first sealing ring 60 in the first waterproof groove 11a; and / or, a second waterproof groove 30a is provided on the outer wall of the terminal 30, and a second sealing ring 70 is provided in the second waterproof groove 30a. The wall of the fixing hole 21 limits the second sealing ring 70 in the second waterproof groove 30a.

[0033] Understandably, by providing a first waterproof groove 11a on the wall of the limiting hole 11, and a first sealing ring 60 in the first waterproof groove 11a, the first sealing ring 60 is confined within the first waterproof groove 11a by the wall of the limiting hole 11. When liquid enters from the gap between the insulating core 20 and the socket housing 10, the liquid and stains can be blocked between the first sealing ring 60 and the waterproof sealing ring 40 due to the interaction between the first sealing ring 60, the first waterproof groove 11a, and the outer wall of the insulating core 20, thereby achieving a double-sealed waterproof mechanism between the insulating core 20 and the socket housing 10. To prevent liquid or stains from entering the interior of the insulating core 20 from the gap between the terminal 30 and the insulating core 20, a second waterproof groove 30a can be provided on the outer wall of the terminal 30, and a second sealing ring 70 can be provided within the second waterproof groove 30a. The second sealing ring 70 is confined within the second waterproof groove 30a by the wall of the fixing hole 21. When liquid or stains enter the interior of the insulating core 20 from the end of the terminal 30 away from the barrier 50 between the terminal 30 and the insulating core 20, the liquid or stains will not flow further into the interior of the insulating core 20 due to the action between the second sealing ring 70 and the wall of the second waterproof groove 30a and the inner wall of the insulating core 20.

[0034] Further, in one embodiment of the present invention, the assembly hole 12 includes a first mounting hole 12a and a second mounting hole 12b. The first mounting hole 12a is disposed between the limiting hole 11 and the second mounting hole 12b, and the diameter of the second mounting hole 12b is larger than the diameter of the first mounting hole 12a. The barrier 50 includes a gasket 51, a sealing body 52, and a tail buckle 53. The gasket 51 and the sealing body 52 are disposed in the second mounting hole 12b, and the tail buckle 53 is fastened to the tail end of the socket housing 10.

[0035] Understandably, by setting the diameter of the second mounting hole 12b to be larger than the diameter of the first mounting hole 12a, a stepped mounting structure is formed in the assembly hole 12. Utilizing the step formed between the first mounting hole 12a and the second mounting hole 12b, the gasket 51 and the sealing body 52 can be confined within the second mounting hole 12b, preventing displacement of the gasket 51 and the sealing body 52 within the assembly hole 12. The tail clip 53 engages with the tail end of the socket housing 10, thereby preventing the gasket 51 and the sealing body 52 from falling out of the second mounting hole 12b. Understandably, a wire-passing hole is formed on the barrier member 50. The terminal 30 includes a connecting end 31, a fixing end 32, and a wiring terminal 33 connected in sequence, with the fixing end 32 and the wiring terminal 33 disposed in the fixing hole 21. The wiring terminal 33 connects to a cable, and the other end of the cable passes through the wire-passing hole to connect to other devices.

[0036] Furthermore, in one embodiment of the present invention, the barrier member 50 further includes a first shielding ring 54 and a second shielding ring 55. The first shielding ring 54 includes an annular portion 541 and a plurality of elastic portions 542 connected to the annular portion 541. The annular portion 541 is disposed in the first mounting hole 12a. One end of the elastic portion 542 is connected to the annular portion 541, and the other end of the elastic portion 542 extends toward the axis of the annular portion 541. The second shielding ring 55 is disposed inside the first shielding ring 54 and abuts against the elastic portion 542.

[0037] Understandably, the second shielding ring 55 is fitted onto the outer wall of the cable, and the elastic portion 542 of the first shielding ring 54 abuts against the second shielding ring 55, thereby constructing a continuous conductive path to achieve the shielding function. Preferably, the socket housing 10 is made of a conductive material, such as metal. Preferably, the mounting panel 80 is made of a conductive material, such as metal.

[0038] Furthermore, in one embodiment of the present invention, the wall of the limiting hole 11 is provided with a boss 111, and the insulating core 20 is provided with a limiting recess 23 corresponding to the boss 111, and the boss 111 is limited and engaged with the limiting recess 23.

[0039] Understandably, the engagement between the boss 111 and the limiting recess 23 prevents the insulating core 20 from moving axially relative to the socket housing 10, thus ensuring the connection accuracy and stability between the insulating core 20 and the socket housing 10.

[0040] Furthermore, in one embodiment of this utility model, the terminal 30 includes a connecting end 31, a fixing end 32, and a wiring end 33 connected in sequence. The fixing end 32 and the wiring end 33 are disposed in the fixing hole 21. The fixing end 32 is provided with a protrusion 321 at one end near the connecting end 31, and a stepped groove 322 at one end near the wiring end 33. A support arm 24 is provided protruding from the wall of the fixing hole 21. The support arm 24 abuts against the stepped groove 322. A claw 25 is also provided at one end of the support arm 24 away from the stepped groove 322. The claw 25 abuts against the protrusion 321 at one end away from the support arm 24.

[0041] Understandably, by abutting the support arm 24 against the stepped groove 322, the terminal 30 is prevented from falling out of the insulating core 20 along the axial direction. By abutting the claw 25 against the protrusion 321, the terminal 30 is prevented from entering the insulating core 20 along the axial direction. The cooperation of the support arm 24 and claw 25 with the stepped groove 322 and protrusion 321 prevents the terminal 30 from reciprocating relative to the insulating core 20 along the axial direction. This configuration prevents the terminal 30 from shaking or moving relative to the insulating core 20 during use, improving overall stability. Preferably, the end of the protrusion 321 away from the stepped groove 322 is an arc surface. Understandably, setting the end of the protrusion 321 away from the stepped groove 322 to an arc surface facilitates the installation of the terminal 30.

[0042] This utility model also relates to a connecting assembly 200, including a mounting panel 80 and the aforementioned connector 100. The mounting panel 80 has a through hole 81, and an abutment portion 82 is provided around the through hole 81. The other end of the insulating core 20 extends through the through hole 81. The abutment portion 82 abuts against the socket housing 10 and covers the opening of the waterproof groove 100b. Since this connector 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0043] Understandably, the mounting panel 80 is provided with a through hole 81, through which the end of the insulating core 20 away from the socket housing 10 protrudes. The mounting panel 80 is provided with an abutment portion 82 around the through hole 81. The abutment portion 82 abuts against the socket housing 10 and covers the opening of the waterproof groove 100b. This arrangement allows the abutment portion 82 to cover the opening of the waterproof groove 100b when the mounting panel 80 is connected to the socket housing 10, further preventing water and dirt from entering the interior of the socket housing 10 from between the socket housing 10 and the insulating core 20.

[0044] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
