[0002] High-voltage connectors play an important role in new energy vehicles, transmitting current or optical signals between modules of the vehicle. With the development and popularization of new energy vehicles, high-voltage connectors are widely used in vehicles as important components of modular connections in new energy vehicles.

[0003] The high-voltage connector includes a terminal and a cable. One end of the terminal is connected to one end of the cable, and the other end of the terminal is a plug-in end for plugging and connecting with the target device. The other end of the cable is an exposed end and is exposed to the connector. In an elbow high-voltage connector, the cable is routed out in a single direction inside the connector, and the cable route is generally at right angles to the terminal's plug-in direction. This results in a high height difference between the terminal's plug-in end and the cable's exposed end, which makes this elbow high-voltage connector occupy more assembly space to a certain extent, which is not conducive to the optimization of the vehicle layout.

[0034] An embodiment of the present application provides a high-voltage connector that can withstand and transmit high-voltage current, such as 500-1000V voltage. In new energy vehicles, the high-voltage connector can build a bridge for current transmission between electronic units such as battery packs, motors, motor controllers, air-conditioning compressors, DCDC converters, and charging systems.

[0035] Reference Figure 1 , shows a front view of the high voltage connector 100 according to an embodiment of the present application; Figure 2 , showing a cross-sectional view of the high voltage connector 100 according to an embodiment of the present application; referring to Figure 3 , shows an exploded view of the high voltage connector 100 described in an embodiment of the present application.

[0036] like Figures 1 to 3 As shown, the high-voltage connector 100 may specifically include: a sheath 10, the sheath 10 is formed with a first mounting groove 11 for accommodating a cable 30, the first mounting groove 11 has a first end and a second end, the cable 30 is suitable for being connected to the terminal 20 at the first end and passing through the first mounting groove 11 at the second end, the terminal 20 is extended along a first direction, the first end and the second end of the first mounting groove 11 are spaced apart in the first direction, and in the first direction, the second end is arranged close to the side of the terminal 20 away from the first end.

[0037] It can be understood that when the terminal 20 is extended in the first direction, since the first end and the second end of the first mounting groove 11 of the sheath 10 are spaced apart in the first direction, and the second end is arranged close to the side of the terminal 20 away from the first mounting groove 11, the end of the terminal 20 away from the first mounting groove 11 forms a plug-in end and is used for plug-in connection with the target device, and the end of the cable 30 that comes out from the second end of the first mounting groove 11 and the plug-in end of the terminal 20 can have a smaller height difference,

[0038] In actual application, the sheath 10 is further formed with a second mounting groove 12 for accommodating the terminal 20. The second mounting groove 12 extends along the first direction so that the terminal 20 can be extended along the first direction. The first mounting groove 11 has an extension direction different from that of the first mounting groove 11 and at least partially extends along the second direction. One end of the terminal 20 is connected to one end of the cable 30 to form a conductor line of the cable 30. The sheath 10 can provide support and protection for the terminal 20 and the cable 30, thereby improving the strength of the terminal 20 and the cable 30, extending the service life of the high-voltage connector 100, and playing an insulating protection role between the conductor line of the cable 30 and the housing 40.

[0039] The sheath 10 can be made of plastic material. The first mounting groove 11 and the second mounting groove 12 are receiving grooves arranged inside the sheath 10. The first mounting groove 11 is used to install the cable 30, and the second mounting groove 12 is used to install the terminal 20; wherein the first mounting groove 11 has a first end and a second end; the second mounting groove 12 has an extension direction different from that of the first mounting groove 11. After the terminal 20 and the cable 30 are assembled into the sheath 10, one end of the terminal 20 is connected to the cable 30, and the other end forms a plug-in end and is used to connect the target device; the cable 30 is arranged along the extension direction of the first mounting groove 11, and one end is connected to the terminal 20, and the other end passes through the first mounting groove 11 to form an outlet end and is exposed to the high-voltage connector 100, and the outlet end of the cable 30 also extends toward the plug-in end of the terminal 20.

[0040] It should be noted that in the embodiment of the present application, the terminal 20 and the cable 30 are ultrasonically welded to form the conductor wire of the cable 30. Of course, the terminal 20 and the cable 30 can also be connected by crimping or crimping to meet the current transmission requirements between the terminal 20 and the cable 30.

[0041] In some optional embodiments of the present application, the first installation groove 11 at least partially extends toward the second direction, and the second direction is arranged at an angle to the first direction.

[0042] Specifically, the first mounting groove 11 is a curved groove extending at least partially along the second direction. For example, the curved groove may include a plurality of straight segments connected by bends, or a plurality of straight segments and curved segments connected by bends, wherein one end of the first mounting groove 11 is connected to the second mounting groove 12, and the other end is located on the same side of the second mounting groove 12 away from the first mounting groove 11, thereby reducing the height difference between the outlet end of the cable 30 and the plug-in end of the terminal 20.

[0043] It should be noted that the first mounting groove 11 can also be set as a straight groove. Specifically, one end of the first mounting groove 11 is connected to the second mounting groove 12, and the first mounting groove 11 as a whole extends in a straight line along the second direction and is arranged at an angle with the second mounting groove 12. The angle is an acute angle. Since the angle between the first mounting groove 11 and the second mounting groove 12 is an acute angle, the outlet end of the cable 30 and the plug-in end of the terminal 20 can have a small height difference. For example, the angle between the first mounting groove 11 and the second mounting groove 12 can be 20°, 30°, 45°, etc. In practical applications, when the first mounting groove 11 is a straight groove, it can be more convenient to assemble the cable 30 into the first mounting groove 11.

[0044] In some optional embodiments of the present application, on a plane perpendicular to the extension direction of the first installation groove 11 , the cross-sectional shape of the first installation groove 11 is a circle that is adapted to the cable 30 .

[0045] Specifically, the circular diameter of the cross section of the first mounting groove 11 is larger than the diameter of the cable 30. Setting the cross-sectional shape of the first mounting groove 11 to a circle that matches the cable 30 can also provide more uniform support and protection for the cable 30 in the axial direction. At the same time, the circular inner wall of the first mounting groove 11 also avoids the setting of a folded corner, thereby preventing the outer wall of the cable 30 from contacting the folded corner of the inner wall of the first mounting groove 11, causing the outer wall of the cable 30 to be squeezed and deformed, affecting the safety performance of the high-voltage connector 100.

[0046] In some optional embodiments of the present application, the first mounting groove 11 includes a first straight section 111, a bent section 112, and a second straight section 113 connected in sequence, the first straight section 111 is arranged near the first end of the first mounting groove 11, the second straight section 113 is arranged near the second end of the first mounting groove 11, the first straight section 111 and the second straight section 113 both extend along a third direction, and the bent section 112 is bently connected between the first straight section 111 and the second straight section 113; the third direction is perpendicular to the first direction.

[0047] In actual applications, since the terminal 20 and the cable 30 need to be ultrasonically welded, in the related art, in the welding jig of the terminal 20 and the cable 30, the terminal 20 and the cable 30 are generally set at a right angle. Therefore, the end of the second mounting groove 12 connected to the first mounting groove 11 is set as a straight section, and the straight section extends along a third direction perpendicular to the first direction, so that the angle between the terminal 20 and the cable 30 after connection is required to be a right angle. Such a structure facilitates ultrasonic welding between the terminal 20 and the cable 30.

[0048] Furthermore, since the outlet end of the elbow high-voltage connector 100 is generally arranged to be perpendicular to the extension direction of the terminal 20, when the second straight section 113 and the first straight section 111 both extend in the third direction, the cable 30 in the second straight section 113 can be outlet from the outlet end of the elbow high-voltage connector 100 in the third direction, that is, the outlet direction of the cable 30 is perpendicular to the extension direction of the terminal 20, thereby reducing the bending probability of the cable 30. When performing the circuit layout of the entire vehicle, the outlet direction of the cable 30 can be adjusted according to the layout between the electronic units, and the bending of the cable 30 can be minimized.

[0049] In some optional embodiments of the present application, the bending section 112 includes at least one of a straight line section and a curved line section. For example, the bending section 112 can be set as a straight line as a whole section, or as a curve as a whole section, such as a parabola, an S-shaped curve, etc. Alternatively, the bending section 112 can also be set in the form of a straight line in the middle of the curves at both ends. The present application does not make specific limitations on this.

[0050] In the embodiment of the present application, the projections of the first straight section 111, the second straight section 113 and the bent section 112 in the plane perpendicular to the third direction z are the first projection, the second projection and the third projection respectively, and along the first direction x, the third projection is located between the first projection and the second projection. That is, along the first direction x, the projection of the bent section 112 in the plane perpendicular to the third direction z is located between the projections of the first straight section 111 and the second straight section 113 in the plane perpendicular to the third direction z. It should be noted that, with such an arrangement, in the first direction x, the highest point of the bent section 112 is not higher than the first straight section 111, and the lowest point is not lower than the second straight section 113, thereby ensuring that the volume of the high-voltage connector is small and can be easily processed and produced.

[0051] like Figure 2 As shown, the bending section 112 extends along the second direction, one end of the bending section 112 is connected to the first straight section 111, and the other end extends toward the side of the first end of the terminal 20 away from the first mounting groove 11, and is connected to the second straight section 113. The angle between the third direction and the second direction ranges from 20° to 45°.

[0052] It should be noted that the angle between the third direction and the second direction is the bending angle of the bending section 112. Figure 2The angle α in the figure is the bending angle of the bending section 112. For example, the bending angle of the bending section 112 can be 20°, 30°, 45°, etc. By setting the angle range to 20° to 45°, the height difference between the plug-in end of the terminal 20 and the outlet end of the cable 30 is reduced, while also preventing the bending angle of the bending section 112 from being too large to affect the transmission effect and service life of the cable 30. In order to ensure the transmission effect of the cable 30, it is necessary to avoid setting the bending angle of the bending section 112 too large, for example, exceeding 45°.

[0053] In practical applications, the angle can be designed according to the layout of the electronic units at both ends of the high-voltage connector 100. When the height difference between the electronic units at both ends of the high-voltage connector 100 is small, the bending angle can be set to be larger, thereby reducing the height difference between the plug-in end of the terminal 20 and the outlet end of the cable 30; similarly, when the height difference between the electronic units at both ends of the high-voltage connector 100 is large, the bending angle can be set to be smaller, thereby increasing the height difference between the plug-in end of the terminal 20 and the exposed end of the cable 30.

[0054] In some optional embodiments of the present application, the sheath 10 is a split structure, including a sheath body 13 and a sheath cover plate 14, and the sheath body 13 and the sheath cover plate 14 are detachably connected, so as to facilitate the cable 30 and the terminal 20 to enter and exit the first installation slot 11 and the second installation slot 12. Figure 5 , shows a schematic diagram of the assembly of the cable 30 and the terminal 20 and the sheath body 13 described in the embodiment of the present application; in actual applications, after the terminal 20 and the cable 30 are assembled with the sheath body 13, the sheath cover 14 can be connected to the sheath body 13, thereby forming the sheath 10 as a whole, increasing the strength of the terminal 20 and the cable 30, and playing an insulating protection role between the conductor wire of the cable 30 and the shell 40.

[0055] Reference Figure 4 , shows a schematic diagram of the structure of the sheath body 13 according to the embodiment of the present application, such as Figure 4 As shown, the sheath body 13 includes a first side and a second side disposed away from each other along a first direction, the first side is provided with an opening, and the first mounting groove 11 is provided on the first side of the sheath body 13 and communicates with the opening; Figure 6 , shows a schematic diagram of the structure of the sheath cover plate 14 according to an embodiment of the present application, such as Figure 6 As shown, the sheath cover plate 14 is a separate structure, and the sheath cover plate 14 is detachably connected to the first side of the sheath body 13 to block the opening of the sheath body 13, thereby facilitating the cable 30 and the terminal 20 to enter and exit the first installation slot 11 and the second installation slot 12.

[0056] It should be noted that when the first installation groove 11 is a curved groove, the cable 30 also extends in a curved manner in the first installation groove 11 , so the design of the sheath 10 should preferably be split, so as to make it easier to assemble the cable 30 into the curved first installation groove 11 .

[0057] In the embodiment of the present application, the sheath body 13 is provided with a first clamping portion 131 , and the sheath cover plate 14 is provided with a second clamping portion 141 , and the second clamping portion 141 is clamped to the first clamping portion 131 .

[0058] Specifically, both sides of the sheath body 13 are provided with first clamping parts 131. On one side of the sheath body 13, the number of first clamping parts 131 can be set to multiple, and the multiple first clamping parts 131 are evenly spaced along the length direction of the sheath body 13, and the number and position of the second clamping parts 141 provided on the sheath cover plate 14 match the number and position of the first clamping parts 131. The clamping cooperation of the multiple first clamping parts 131 and the multiple second clamping parts 141 improves the connection strength between the sheath body 13 and the sheath cover plate 14, and ensures the insulation protection effect of the sheath 10 on the conductor wire of the cable 30 and the housing 40.

[0059] In the embodiment of the present application, the first clamping portion 131 is one of a clamping slot and a buckle, and the second clamping portion 141 is the other of the clamping slot and the buckle; the buckle is clamped to the clamping slot.

[0060] For example, the first clamping portion 131 provided on the sheath body 13 is a buckle, and the second clamping portion 141 provided on the sheath cover plate 14 is a slot. In a specific application, the sheath cover plate 14 can be assembled with the sheath body 13 along the height direction of the sheath body 13, and the buckles on both sides of the sheath body 13 are inserted into the slots on both sides of the sheath cover plate 14, thereby completing the connection between the sheath body 13 and the sheath cover plate 14.

[0061] like Figures 1 to 3 As shown, the high voltage connector 100 further includes a housing 40 . The housing 40 is provided with a receiving cavity, and the sheath 10 is disposed in the receiving cavity of the housing 40 .

[0062] Specifically, the shell 40 is made of metal, and the shape of the accommodating cavity of the shell 40 matches the external dimensions of the sheath 10, thereby providing better protection for the sheath 10. In practical applications, for a high-voltage connector 100 with a shielding function, in addition to the shielding layer required for the cable, the connector shell 40 is made of metal material and can also provide electromagnetic shielding protection for the inside of the connector.

[0063] like Figure 3 As shown, the high voltage connector 100 further includes various structural accessories, such as a connecting ring 51 , a crimping ring 52 , a cable sealing ring 53 , a tail buckle 54 , and an end face sealing ring 55 .

[0064] like Figure 7 As shown, the connecting ring 51 is provided with a first spring piece 511, a second spring piece 512 and a convex structure 513, wherein the first spring piece 511 is clamped on the sheath cover plate 14, and the sheath cover plate 14 is also provided with a third clamping portion 142 for fixing the first spring piece 511, and the first spring piece 511 is assembled and matched with the third clamping portion 142 on the sheath cover plate 14, and the third clamping portion 142 can be a card slot; the second spring piece 512 and the crimping ring 52 are connected and conducted by riveting with the shielding wire of the cable 30, and the convex structure 513 is in contact with the inner wall of the shell 40, so as to achieve shielding conduction with the shell 40. It should be noted that when the sheath 10 is split, the connecting ring 51 is also correspondingly provided as two semicircular connecting rings 51, and is respectively provided close to the sheath body 13 and the sheath cover plate 14.

[0065] The crimping ring 52 is made of metal, is sleeved on the outside of the cable 30 , and provides support for the connecting ring 51 .

[0066] The cable sealing ring 53 is made of silicone, the inner ring of the cable sealing ring 53 contacts the cable 30 , and the outer ring contacts the inner wall of the housing 40 , thereby achieving sealing of the tail of the outlet end of the cable 30 of the high-voltage connector 100 .

[0067] The tail buckle 54 is made of plastic material and is used to limit the internal cable sealing ring 53 to prevent it from falling out.

[0068] The end face sealing ring 55 is made of silicone rubber. After the high-voltage connector 100 is plugged into the target electronic unit, the end face sealing ring 55 abuts against the box of the target electronic unit, thereby achieving sealing between the high-voltage connector 100 and the box.

[0069] It should be noted that the above structural accessories are common structural accessories in the high-voltage connector 100 in the prior art. The present application will not elaborate on the structures of the above components. The assembly of the above structural accessories can be carried out in the common assembly method in the art.

[0070] It should be noted that in some optional embodiments of the present application, the sheath 10 is provided with a plurality of first mounting grooves 11 and a plurality of second mounting grooves 12 , wherein the plurality of first mounting grooves 11 and the plurality of second mounting grooves 12 are arranged in parallel along the width direction of the high-voltage connector 100 .

[0071] The present application also discloses an electrical device, which includes the high-voltage connector 100 as described above.

[0072] The present application also discloses a vehicle, which includes the above-mentioned high-voltage connector 100 or electrical equipment.

[0073] In practical applications, the high-voltage connector 100 can build a bridge for current transmission between electronic units such as the vehicle's battery pack, motor, motor controller, air-conditioning compressor, DCDC converter, charging system, etc.; and keep the signal distortion and energy loss between the electronic units from occurring.

[0074] In summary, in the embodiment of the present application, the terminal is extended along the first direction. Since the first end and the second end of the first mounting groove of the sheath are spaced apart in the first direction, and in the first direction, the second end is arranged close to the side of the terminal away from the first mounting groove, the end of the terminal away from the first mounting groove forms a plug-in end and is used for plugging and connecting with the target device. The end of the cable outlet from the second end of the first mounting groove and the plug-in end of the terminal can have a smaller height difference. Compared with the common method of setting the terminal and the cable at right angles in the elbow connector of the prior art, the height difference between the cable outlet end and the terminal plug-in end is reduced. The technician can design the spacing distance between the first end and the second end of the first mounting groove in the first direction by themselves, thereby improving the flexibility of the assembly height between the cable outlet end and the terminal plug-in end of the high-voltage connector, which is beneficial to the layout design of the entire vehicle.
