Description

Technical Field

[0001] This utility model relates to the field of high-voltage connectors, specifically to a shielding structure for a high-voltage connector and a high-voltage connector. Background Technology

[0002] New energy vehicle motors have high voltage and current, resulting in strong electromagnetic radiation that can easily cause electromagnetic interference to other electronic components in the vehicle. Therefore, shielded high-voltage cables are generally used for current transmission to reduce external radiation and prevent other components from malfunctioning due to electromagnetic interference. For integrated solutions, the motor controller, motor, and reducer are highly integrated, with the motor controller and motor transmitting current through a high-voltage connector. High-voltage connectors typically use wave springs, metal springs, etc., for shielding, resulting in complex structures and high manufacturing costs.

[0003] Existing connectors have complex shielding structures with many components, making assembly difficult and resulting in high R&D and production costs. At the same time, existing connector shielding structures are relatively fragile and are prone to detachment under stress, leading to shielding failure and overall weak shielding performance.

[0004] For example, Chinese patent CN115441242A discloses a high-voltage connector shielding structure, which reduces the production process time by setting the first connecting component, the second connecting component, the third connecting component and the fourth connecting component as a snap-fit ​​structure, while making the connection between the components tighter.

[0005] However, the high-voltage connector shielding structure of the above scheme requires the fastening of the first connecting component, the second connecting component, the third connecting component, and the fourth connecting component, which is complicated to operate. Moreover, after the four components are fastened, the size of the shielding structure is fixed. Electrical connection between shielding covers can only be achieved by inserting it into a shielding cover of the appropriate size. In the event of human calculation or operational errors, inserting it into a shielding cover of an unsuitable size will damage the shielding cover of the high-voltage connector. Utility Model Content

[0006] To overcome the problems of existing high-voltage connector shielding structures requiring the fastening of a first, second, third, and fourth connecting component, which is complex and results in a fixed size shielding structure after the four components are fastened, allowing electrical connection between shielding covers only when inserted into a shielding cover of the appropriate size, and the potential damage to the high-voltage connector shielding cover due to human error in calculation or operation, this utility model provides a shielding structure for a high-voltage connector and a high-voltage connector.

[0007] The technical solution of this utility model is as follows:

[0008] On the one hand, this utility model provides a shielding structure for a high-voltage connector, including a first shielding cover and a second shielding cover.

[0009] The first shield is disposed in the first receiving cavity of the plug assembly and surrounds the crown spring for receiving the cable in the first receiving cavity. The first shield is provided with a plurality of elastic parts and a gap is left between adjacent elastic parts. The elastic parts are sleeved on the second shield and are elastically connected to the second shield, so that the first shield and the second shield are electrically connected.

[0010] The second shield is disposed within the second receiving cavity of the socket assembly and surrounds the plug terminals within the second receiving cavity.

[0011] Furthermore, the first shielding cover includes a first main body, and the elastic part is a first elastic arm extending upward from the first main body. The first elastic arm includes a connecting part and a bending part. The connecting part connects the first main body and the bending part. The bending part is provided with a first protrusion for secure connection with the second shielding cover.

[0012] Furthermore, the first main body extends downward to form a second elastic arm, which is provided with an inwardly bent second protrusion, so that the second protrusion is elastically connected to the cable shield.

[0013] Furthermore, the second shielding cover includes a second main body, and the second main body extends upward with a third elastic arm, which is elastically connected to an external device.

[0014] Furthermore, there is a gap between adjacent first elastic arms, a gap between adjacent second elastic arms, and a gap between adjacent third elastic arms.

[0015] On the other hand, this utility model provides a high-voltage connector, including a socket assembly, a plug assembly, a crown spring fixing structure, and a shielding structure for the high-voltage connector.

[0016] The crown spring fixing structure is disposed in the first receiving cavity within the plug assembly and is used to limit the crown spring that houses the cable.

[0017] The first shield of the shielding structure of the high-voltage connector is limited in the plug assembly by the cooperation of the crown spring fixing structure and the limiting part in the first receiving cavity;

[0018] The second shield of the shielding structure of the high-voltage connector is confined within the socket assembly.

[0019] Furthermore, the crown spring fixing structure includes a crown spring insulating sleeve and a crown spring fixing sleeve.

[0020] The crown spring fixing sleeve and the crown spring insulating sleeve are engaged, forming a space for receiving the crown spring.

[0021] The crown spring fixing sleeve is provided with a first buckle, and the crown spring insulating sleeve is provided with a second buckle. The first buckle and the second buckle cooperate to limit the crown spring within the receiving space.

[0022] Furthermore, the crown spring fixing sleeve is cylindrical, and the inner circumference of the crown spring fixing sleeve is arrayed with multiple plate ribs, and the upper surface of the plate ribs is provided with protruding ribs, which abut against the outer side of the crown spring.

[0023] Furthermore, the side of the rib near the crown spring insulating sleeve is bent inward to form a first buckle, and the crown spring is provided with a groove at the position of the first buckle. The first buckle is engaged with the groove to restrict the crown spring from moving downward.

[0024] The crown spring insulating sleeve is cylindrical, and the end of the crown spring insulating sleeve is recessed to form a third stop, which is used to abut against the upper end of the crown spring and restrict the crown spring from moving upward.

[0025] Furthermore, a first hook is provided on the side of the crown spring insulating sleeve near the crown spring fixing sleeve, and a gap is left between adjacent first hooks. A second hook is provided at the corresponding position of the crown spring fixing sleeve. The first hook and the second hook cooperate to engage the crown spring insulating sleeve and the crown spring fixing sleeve.

[0026] Furthermore, the outer wall of the crown spring insulating sleeve is provided with a first abutting part and a first limiting groove above the first hook, the first abutting part and the first limiting groove being spaced apart.

[0027] The plug assembly has a fourth stop that mates with the first abutment and a first limiting rib that mates with the first limiting groove in the first terminal receiving groove. The first abutment mates with the fourth stop and the first limiting groove mates with the first limiting rib, which are used to limit the rotation of the crown spring structure of the high-voltage connector.

[0028] According to the above-described solution, the advantages of this utility model are as follows: the first shielding cover of this utility model is provided with an elastic part, which can move within the deformation range and abut against second shielding covers of different sizes. Even in the event of human calculation or operational errors, it can still stably abut against the second shielding cover and achieve electrical connection with the second shielding cover. In use, it is only necessary to put the bottom of the second shielding cover inside the first shielding cover, and the elastic part of the first shielding cover can abut against the outer side wall of the second shielding cover. It is convenient and quick to use. Moreover, after the first shielding cover is separated from the second shielding cover, the elastic part of the first shielding cover will automatically reset, resulting in a longer service life.

[0050] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0051] It should be noted that the terms "comprising" and "having," and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. Terms such as "set up" should be interpreted broadly; for example, it can refer to a fixed connection, a detachable connection, or an integral part; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements or the interaction between two elements, unless otherwise expressly defined. Terms such as "upper," "lower," "left," "right," "front," "rear," and "bottom" indicate orientations or positions based on the orientations or positions shown in the accompanying drawings, and are only for ease of description and should not be construed as limiting the present technical solution.

[0052] like Figures 1-11 As shown, a shielding structure for a high-voltage connector includes a first shielding cover 43 and a second shielding cover 44. The first shielding cover 43 is disposed within a first receiving cavity 411 of the socket housing 401 of the plug assembly 41 and surrounds the crown spring 3 for housing the cable 413 within the first receiving cavity 411. The first shielding cover 43 has a plurality of elastic portions with gaps between adjacent elastic portions. The elastic portions are fitted over the second shielding cover 44 and are elastically connected to the second shielding cover 44, thereby electrically connecting the first shielding cover 43 and the second shielding cover 44. The second shielding cover 44 is disposed within a second receiving cavity 421 of the socket assembly 42 and surrounds the plug terminal 423 within the second receiving cavity 421. The socket assembly 42 has a plug housing 402, and the plug can extend downward to form a plug-in portion 424, which forms the second receiving cavity 421. The first shield 43 and the second shield 44 are elastically connected, ensuring that the high-voltage connector 4 remains firmly connected under external pressure or other conditions, preventing interference from the high-voltage connector 4 and protecting it. Furthermore, the socket assembly 42 automatically resets when detached from the plug assembly 41, extending the service life of the first shield 43.

[0053] In a preferred embodiment, such as Figure 1 As shown, the first shielding cover 43 includes a first main body 431 and an elastic part, which is a first elastic arm 432 extending upward from the first main body 431. The first elastic arm 432 includes a connecting part 4321 and a bending part 4322. The connecting part 4321 connects the first main body 431 and the bending part 4322. The bending part 4322 is provided with a first protrusion 4323 for secure connection with the second shielding cover 44. During use, the first protrusion 4323 of the first elastic arm 432 contacts the second shielding cover 44, realizing the electrical connection between the first shielding cover 43 and the second shielding cover 44. Driven by the connecting part 4321, the bending part 4322 can move within the deformation space of the connecting part 4321. Even if the second shielding cover 44 has size deviations or positional shifts due to human error, the first elastic arm 432 can still abut against the outer wall of the second shielding cover 44, realizing the electrical connection between the first shielding cover 43 and the second shielding cover 44. Each first elastic arm 432 is an individual unit that can accommodate second shields 44 of various sizes.

[0054] In a preferred embodiment, such as Figure 1As shown, a second elastic arm 433 extends downward from the first main body 431. The second elastic arm 433 is provided with an inwardly bent second protrusion 4331, which allows the second protrusion 4331 to elastically connect with the shielding cover of the cable 413. The second protrusion 4331 can better abut against the shielding cover of the cable 413, thereby achieving an electrical connection between the first shielding cover 43 and the shielding cover of the cable 413. The second elastic arm 433 can move within the deformation space. Even if the shielding cover of the cable 413 deviates in size or position due to human error, the elastic arm can still abut against the outer wall of the shielding cover of the cable 413, achieving an electrical connection between the first shielding cover 43 and the shielding cover of the cable 413. Each second elastic arm 433 is an individual unit and can accommodate shielding covers of more sizes of cable 413.

[0055] In a preferred embodiment, such as Figure 2 As shown, the second shielding cover 44 includes a second main body 441, from which a third elastic arm 442 extends upward. The third elastic arm 442 is elastically connected to external equipment. The third elastic arm 442 extends outward and upward a certain distance, then upward a certain distance again, then inward and upward a certain distance, and finally upward a certain distance again. This allows the third elastic arm 442 to connect to external equipment of various sizes and to maintain a tight connection. The third elastic arm 442 can move within its deformation range. Even if the external equipment's size deviates or its position shifts due to human error, the third elastic arm 442 can still abut against the outer wall of the external equipment, achieving electrical connection between the second shielding cover 44 and the external equipment. Each second elastic arm 433 is an independent unit, capable of accommodating external equipment of various sizes.

[0056] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, there is a gap between adjacent first elastic arms 432, a gap between adjacent second elastic arms 433, and a gap between adjacent third elastic arms 442. The purpose of this arrangement is to ensure that there is sufficient distance between the first elastic arms 432, the second elastic arms 433, and the third elastic arms 442 to ensure deformation in each direction.

[0057] like Figures 3-11As shown, a high-voltage connector includes a socket assembly 42, a plug assembly 41, a crown spring fixing structure, and a shielding structure of the high-voltage connector 4 according to any of the above-described solutions. The crown spring fixing structure is disposed in the first receiving cavity 411 of the socket housing 401 within the plug assembly 41, and is used to limit the crown spring 3 that houses the cable 413. The first shielding cover 43 of the shielding structure of the high-voltage connector 4 is limited in the plug assembly 41 by cooperating with the limiting part in the first receiving cavity 411 through the crown spring fixing structure. The second shielding cover 44 of the shielding structure of the high-voltage connector 4 is limited in the socket assembly 42.

[0058] In a preferred embodiment, such as Figure 6 As shown, the lower end of the crown spring fixing sleeve 1 is provided with a first stop 101 that abuts against the lower end of the first main body 431, and the first terminal receiving groove 412 (the first terminal receiving groove 412 is provided in the first receiving cavity 411 for receiving the crown spring) is provided with a second stop 4123 that abuts against the upper end of the first main body 431, thereby fixing the crown spring 3 in the first terminal receiving groove 412.

[0059] In a preferred embodiment, such as Figure 5 , Figure 6 , Figure 7 As shown, the crown spring fixing structure includes a crown spring insulating sleeve 2 and a crown spring fixing sleeve 1. The crown spring fixing sleeve 1 and the crown spring insulating sleeve 2 are snapped together, forming a receiving space for the crown spring 3. A first buckle 103 is provided on the fixing block of the crown spring 3, and a second buckle is provided on the crown spring insulating sleeve 2. The first buckle 103 and the second buckle cooperate to limit the crown spring 3 within the receiving space. The crown spring fixing structure of this utility model does not require a crown spring 3 insertion hole. The crown spring 3 only needs to be placed in the receiving space formed by the snapping of the crown spring fixing sleeve 1 and the crown spring insulating sleeve 2, and the crown spring 3 is fixed in the first buckle 103 and the second buckle, limiting the crown spring 3 within the receiving space. In use, the crown spring 3 only needs to be pushed into the receiving space, which is simple to use and convenient to operate.

[0060] In a preferred embodiment, such as Figure 6 As shown, the crown spring fixing sleeve 1 is cylindrical, with multiple ribs 102 arranged in an array around its inner circumference. The upper surface of each rib 102 has a protruding rib 104, which abuts against the outer surface of the crown spring 3. The purpose of this arrangement is to reduce the contact area between the crown spring fixing sleeve 1 and the crown spring 3 by having the protruding rib 104 abut against the outer surface of the crown spring 3, thereby reducing the frictional force during crown spring 3 insertion. It should be noted that the cylindrical shape of the crown spring fixing sleeve 1 is only a preferred embodiment of this utility model and is not a limitation thereof. Other shapes that can be used to fit the crown spring 3 are also within the protection scope of this utility model.

[0061] In a preferred embodiment, the side of the rib 102 near the crown spring insulating sleeve 2 is bent inward to form a first buckle 103. The crown spring 3 has a groove 301 at the position of the first buckle 103. The first buckle 103 engages with the groove 301 to restrict the crown spring 3 from moving downward. The crown spring insulating sleeve 2 is cylindrical, and its end is recessed to form a third stop 202. The third stop 202 abuts against the upper end of the crown spring 3 to restrict the crown spring 3 from moving upward. In other optional embodiments, the ends of both the crown spring fixing sleeve 1 and the crown spring insulating sleeve 2 are recessed to form stops that restrict the movement of the crown spring 3. Both the crown spring fixing sleeve 1 and the crown spring insulating sleeve 2 are provided with buckles that engage with the groove 301 of the crown spring 3 to restrict the movement of the crown spring 3.

[0062] In a preferred embodiment, the size of the crown spring insulating sleeve 2 is smaller than the size of the crown spring fixing sleeve 1. A first hook 203 is provided on the side of the crown spring insulating sleeve 2 closest to the crown spring fixing sleeve 1. The first hook 203 is located on the outer circumferential surface of the crown spring insulating sleeve 2, facing outwards, and a gap is left between adjacent first hooks 203. A second hook 105 is provided on the corresponding position of the first hook 203 on the crown spring fixing sleeve 1. The second hook 105 is located on the inner circumferential surface of the crown spring fixing sleeve 1, facing inwards. The first hook 203 and the second hook 105 cooperate to engage the crown spring insulating sleeve 2 and the crown spring fixing sleeve 1. In other optional embodiments, the surface of the first hook 203 is provided with a protrusion, and the surface of the second hook 105 is provided with a corresponding groove. The groove and the protrusion cooperate to ensure a more stable connection between the crown spring fixing sleeve 1 and the crown spring insulating sleeve 2.

[0063] In a preferred embodiment, the crown spring fixing structure of the high-voltage connector 4 includes a crown spring insulating sleeve 2 and a crown spring fixing sleeve 1. The outer side wall of the crown spring insulating sleeve 2 is provided with a first abutting portion 204 and a first limiting groove 205 above the first hook 203. The first abutting portion 204 is convex, and the middle part of the first limiting groove 205 is a through structure. The first abutting portion 204 and the first limiting groove 205 are spaced apart and positioned above the spaced positions of adjacent first hooks 203, ensuring a stable connection between the crown spring fixing structure and the first terminal receiving groove 412, and between the crown spring insulating sleeve 2 and the crown spring fixing sleeve 1. The snap-fitting of sleeve 1 does not affect each other. The first terminal receiving groove 412 of plug assembly 41 is provided with a fourth stop 4121 that cooperates with the first abutment 204 and a first limiting rib 4122 that cooperates with the first limiting groove 205. The first abutment 204 cooperates with the fourth stop and the first limiting groove 205 cooperates with the first limiting rib 4122 to limit the rotation of the crown spring fixing structure of high voltage connector 4, so that the crown spring fixing structure of high voltage connector 4 is stably set in the first terminal receiving groove 412, ensuring a continuous and stable electrical connection between socket assembly 42 and plug assembly 41.

[0064] In use, the socket assembly 42 is plugged into the plug assembly 41, the plug terminal 423 extends into the first terminal receiving groove 412, and then the crown spring 3 with the cable 413 is connected to the first terminal receiving groove 412. The plug terminal 423 is inserted into the connecting groove of the crown spring 3 to achieve electrical communication between the crown spring 3 and the plug terminal 423. The crown spring insulating sleeve 2 and the crown spring fixing sleeve 1 cooperate with each other to fix the crown spring 3 in the first terminal receiving groove 412. The shielding assembly is surrounded by the crown spring 3 and the plug terminal 423 to shield the electromagnetic field generated during the power-on process and avoid interference with the signal terminal.
