Description

Technical Field

[0001] The utility model belongs to the technical field of electrical component connection, and more specifically, relates to a high-voltage connector. Background Art

[0002] With the emergence of new energy vehicles and the continuous expansion and high-end development of automotive applications, the requirements for high-voltage connectors are also increasing. Not only are the high-voltage wire harnesses of high-voltage connectors required to be able to transmit power, but the high-voltage cable fixation is also required to be safe and reliable.

[0003] In the prior art, after the high-voltage connector is assembled into a wiring harness, the cables will move axially because they are not effectively fixed when passing through the connector. During the transportation of the wiring harness, the cable movement will drive the shielding assembly to leave its initial position, resulting in the need for repositioning during assembly.

[0004] In addition, in high-voltage connectors, the outer wall of the shielding assembly is crimped into a regular polygon structure and then embedded in the housing. The regular polygon structure is used to abut against the circular inner wall of the housing to prevent the cable from rotating. However, there will be a gap between the regular polygon structure and the inner wall of the housing, and the axial movement of the cable will also cause the crimped regular polygon structure to deviate from its original position, resulting in failure of anti-rotation. Before the high-voltage connector is installed on the equipment, if the cable twists, it will cause the terminal to rotate, and the terminal needs to be readjusted before the terminal can be installed, which increases the workload of assembly.

[0050] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0051] Please also read Figures 1 to 4 , the high-voltage connector provided by the utility model is now described. The high-voltage connector includes a shell 1, a shielding assembly 2, an anti-rotation component 3 and an axial anti-slip structure. The shielding assembly 2 is located inside the shell 1; the shielding assembly 2 is used to crimp cables; the anti-rotation component 3 is located inside the shell 1, and is sleeved on the outer periphery of the shielding assembly 2; the anti-rotation component 3 and the shielding assembly 2 are circumferentially matched, and a circumferential limiting structure 4 is provided between the anti-rotation component 3 and the shell 1; the axial anti-slip structure is arranged between the outer wall of the shielding assembly 2 and the inner wall of the shell 1, and axially connects the shell 1 and the shielding assembly 2, and is used to limit the axial movement of the shielding assembly 2.

[0052] Among them, the cable runs through the shielding component 2, and the cable passes through the shell 1. The shielding layer of the cable is electrically connected to the shielding component 2. Specifically, when the high-voltage connector is connected to the device, the shell 1 is connected to the device, and the shielding layer of the cable forms a loop with the device through the shielding component 2 (or the shielding component 2 and the shell 1) to achieve shielding. It should be noted that if the shielding component 2 is directly electrically connected to the device, then the cable forms a loop with the device through the shielding component 2, and the shell 1 does not need to form an electrical connection relationship, so that the shell 1 can be made of non-metallic materials; if the shielding component 2 is electrically connected to the device through the shell 1, then the cable forms a loop with the device through the shielding component 2 and the shell 1, and the shell 1 needs to be made of metal materials.

[0053] The anti-rotation component 3 is arranged between the shell 1 and the shielding assembly 2. Specifically, the anti-rotation component 3 and the shielding assembly 2 are connected in a detachable manner. When the shielding assembly 2 is assembled to the shell 1 together with the cable, the anti-rotation component 3 is inserted from one end of the shell 1 to limit the anti-rotation component 3 between the shell 1 and the shielding assembly 2. The anti-rotation component 3 and the shielding assembly 2 are limited along the circumferential direction, which can be formed by circumferential clamping limit, circumferential abutment limit, or by respectively setting special-shaped parts on the anti-rotation component 3 and the shielding assembly 2; similarly, a circumferential limit structure 4 is set between the anti-rotation component 3 and the shell 1, which can be specifically formed by circumferential clamping limit and circumferential abutment limit. Since the shell 1 is directly manufactured and formed, and the shell 1 is also connected to the equipment, in order to simplify the structure of the shell 1, it is not recommended to set a special-shaped part on the inner wall of the shell 1.

[0054] The axial anti-slip structure is arranged between the housing 1 and the shielding assembly 2. Specifically, the axial anti-slip structure can be a separate connector to connect the housing 1 and the shielding assembly 2 in the axial direction, or can be a clamping structure, an embedded structure, or an abutting structure formed between the outer wall of the shielding assembly 2 and the inner wall of the housing 1. This embodiment does not specifically limit the axial anti-slip structure, as long as it can limit the relative movement of the shielding assembly 2 and the housing 1 in the axial direction.

[0055] Compared with the prior art, the high-voltage connector provided by the utility model has an anti-rotation part 3 arranged between the shielding component 2 and the shell 1, and the anti-rotation part 3 and the shielding component 2 cooperate with each other in the circumferential direction to limit the circumferential position of the shielding component 2; and a circumferential limiting structure 4 is arranged between the anti-rotation part 3 and the shell 1, which can limit the rotation of the anti-rotation part 3 and the shielding component 2, thereby enhancing the anti-rotation capability and avoiding the rotation of the cable, thereby eliminating the need to readjust the posture position of the cable and the terminal when the high-voltage connector is installed, thereby improving the assembly efficiency; in addition, an axial anti-slip structure is also arranged between the shielding component 2 and the shell 1, which is used to axially connect the shielding component 2 and the shell 1 to prevent relative slippage between the shielding component 2 and the shell 1 and avoid slippage of the cable, thereby eliminating the need to reposition the cable and the shielding component 2 when the high-voltage connector is installed.

[0056] In some embodiments, the shielding assembly 2 may be configured as follows: Figure 2 and Figure 8 The structure shown, see Figure 2 and Figure 8 The shielding assembly 2 includes a shielding outer cylinder 21, a shielding inner cylinder 22, a shielding ring 23 and a stopper 24. The shielding outer cylinder 21 is located inside the housing 1; at least part of the shielding inner cylinder 22 is located inside the shielding outer cylinder 21, and at least part of it extends out of the shielding outer cylinder 21; the shielding ring 23 is arranged at the extended end of the shielding inner cylinder 22; the stopper 24 is sleeved on the extended part of the shielding inner cylinder 22 and outside the shielding ring 23, and is used to fix the shielding ring 23; wherein, the anti-rotation member 3 is sleeved on the outer periphery of the shielding outer cylinder 21, and an axial anti-slip structure is provided between the stopper 24 and the housing 1.

[0057] The shielding ring 23 is electrically connected to the shielding inner tube 22 and is pressed against the shielding inner tube 22 by the stopper 24. The shielding ring 23 is also in contact with the device. The shielding layer of the cable forms a loop with the device through the shielding ring 23 to achieve shielding.

[0058] The limiter 24 and the shielding outer cylinder 21 are respectively sleeved on the shielding inner cylinder 22, and the limiter 24 is located in front of the shielding outer cylinder 21. The limiter 24 can be connected to the shielding inner cylinder 22 by a snap-on method. For example, an elastic hook 243 is provided on the outer wall of the limiter 24, and correspondingly, a card groove is provided on the outer wall of the shielding inner cylinder 22. Preferably, the card groove does not penetrate the side wall of the shielding inner cylinder 22, that is, there is no gap or opening on the shielding inner cylinder 22, so that the shielding inner cylinder 22 can achieve 360° shielding.

[0059] The shielding inner cylinder 22 and the shielding outer cylinder 21 are connected by crimping, and the shielding layer of the cable can be crimped between the shielding inner cylinder 22 and the shielding outer cylinder 21 to improve the connection reliability between the shielding layer and the shielding inner cylinder 22 and the shielding outer cylinder 21. Specifically, the wall thickness of the shielding outer cylinder 21 is smaller than that of the shielding inner cylinder 22, which is convenient for deformation under pressure, and the thickness of the shielding inner cylinder 22 is relatively large, which can also avoid damaging the inner insulation layer of the cable during shield crimping.

[0060] In addition, by adopting the crimping method, the shielding outer cylinder 21 can also be partially deformed to form a non-rotating structure. The inner wall of the anti-rotation component 3 is also provided with a non-rotating structure, and the two cooperate to achieve circumferential connection.

[0061] In some embodiments, the shielding ring 23 may be Fig. 9 The structure shown, see Fig. 9 The shielding ring 23 includes a ring piece 231 and a plurality of elastic clip groups. The plurality of elastic clip groups are arranged on the ring piece 231 at equal intervals along the circumferential direction and extend toward the rear end of the housing 1; the elastic clip group includes a first elastic piece 232 connected to the inner edge of the ring piece 231 and a second elastic piece 233 connected to the outer edge of the ring piece 231; the first elastic piece 232 and the second elastic piece 233 are clamped together at the end of the stopper 24.

[0062] The front end of the shielding inner cylinder 22 is provided with a flange 221 protruding radially outward, and the ring piece 231 is located behind the flange 221, and the ring piece 231 abuts against the flange 221, so that the shielding ring 23 is limited in the axial direction. The first elastic piece 232 is located at the inner edge of the ring piece 231, and is used to be electrically connected to the shielding inner cylinder 22. The second elastic piece 233 is located at the outer edge of the ring piece 231, and is used to contact the device. Specifically, when the housing 1 is connected to the device, the second elastic piece 233 is squeezed and closely contacts the device, which increases the contact area, improves the reliability, and ensures the shielding effect.

[0063] In addition, multiple groups of elastic clip groups are arranged on the ring piece 231 at equal intervals along the circumferential direction, and each two adjacent groups of elastic clip groups are arranged at intervals, which can increase the number of contact points between the shielding ring 23 and the equipment, reduce contact resistance, and improve shielding effectiveness.

[0064] It should be noted that the outer wall and the inner wall of the front end of the stopper 24 are both provided with an avoidance groove for avoiding the elastic clip group. Specifically, the stopper 24 includes a connecting portion 241 and an outer expansion portion 242 which are connected in sequence along the axial direction, and the outer expansion portion 242 protrudes radially outward relative to the connecting portion 241. The connecting portion 241 is provided with an elastic hook 243; the outer expansion portion 242 is used to press the shielding ring 23.

[0065] See also Fig. 9On the basis of the above embodiment, a protrusion 234 protruding outward is provided on the outer wall of the second elastic piece 233. When the device squeezes the second elastic piece 233, the protrusion 234 contacts the device first, and the protrusion 234 can first destroy the oxide layer at the interface of the device, further reducing the contact impedance and improving the shielding effectiveness.

[0066] In some embodiments, the shielding assembly 2 and the housing 1 may be configured as follows: Figure 1 The structure shown, see Figure 1 At least part of the shielding component 2 is located in the inner cavity of the shell 1 , and at least part of it extends out of the front end of the shell 1 , and the extended part of the shielding component 2 is axially abutted against the front end surface of the shell 1 .

[0067] The cable passes through the shielding component 2, and the cable passes through the outer shell 1, and the cable and the shielding component 2 are crimped into one. Specifically, when the high-voltage connector is connected to the device, the front end (i.e., the protruding end) of the shielding component 2 abuts against the device, and the shielding layer of the cable forms a loop with the device through the shielding component 2 to achieve shielding. Since at least part of the shielding component 2 protrudes from the outer shell 1, the cable can be directly connected to the device through the shielding component 2, shortening the current transfer path, reducing the shielding contact resistance, and improving the shielding effectiveness. In addition, the outer shell 1 can be directly made of non-metallic materials, reducing the product weight and manufacturing cost.

[0068] In addition, the protruding portion of the shielding component 2 axially abuts against the front end surface of the shell 1, so that the shielding component 2 and the shell 1 are limited in the axial direction. The abutment position here and the axial anti-slip structure can improve the axial limiting performance between the shielding component 2 and the shell 1.

[0069] Specifically, in the shielding assembly 2 , the front half of the shielding inner tube 22 and the outward expansion portion 242 of the stopper 24 extend out of the outer shell 1 , and the rear end surface of the outward expansion portion 242 abuts against the front end surface of the outer shell 1 .

[0070] In some embodiments, the axial anti-slip structure can be used as follows: Figure 6 and Figure 7 The structure shown, see Figure 6 and Figure 7 The axial anti-slip structure includes at least two groups of bosses 51 and an annular platform 52. At least two groups of bosses 51 are arranged on the outer wall of the shielding assembly 2 at intervals along the circumferential direction and protrude radially outward; the bosses 51 have a first abutting surface 511 facing the front end of the shell 1; the annular platform 52 is arranged on the inner wall of the shell 1; the inner wall of the annular platform 52 is provided with guide grooves 522 corresponding to at least two groups of bosses 51; the annular platform 52 also has a second abutting surface 521 facing the rear end of the shell 1. The annular platform 52 enters the interior of the shell 1 through the guide groove 522, and after the shielding assembly 2 is rotated, the second abutting surface 521 axially abuts against the first abutting surface 511.

[0071] The ring platform 52 is arranged on the inner wall of the housing 1. It can be considered that the ring platform 52 protrudes radially inward on the inner wall of the housing 1. The housing 1 can also be divided into two parts, namely, a main body part 11 and a necking part 12 connected in sequence along the axial direction. Figure 2 and Figure 3 As shown, the necked portion 12 shrinks inwardly relative to the main body 11 , and the necked portion 12 forms the aforementioned annular platform 52 . The rear end surface of the necked portion 12 is the aforementioned second abutting surface 521 .

[0072] Specifically, at least two groups of bosses 51 are respectively arranged on the outer wall of the limiter 24, and the axial connection between the limiter 24 and the housing 1 is utilized to achieve anti-collision.

[0073] The boss 51 protrudes outward, while the annular platform 52 protrudes inward, that is, the inner diameter surrounded by the annular platform 52 is smaller than the outer diameter surrounded by at least two groups of bosses 51, so as to ensure that the first abutting surface 511 and the second abutting surface 521 abut axially, thereby realizing the axial connection relationship between the limiter 24 and the housing 1.

[0074] Since the rear end face of the outwardly expanded portion 242 in the limiter 24 is located in front of the front end face of the shell 1 and the two are abutted, the first abutting surface 511 of the limiter 24 is located behind the second abutting surface 521 of the shell 1 and the two are abutted, that is, the necking portion 12 of the shell 1 is pressed between the rear end face of the outwardly expanded portion 242 of the limiter 24 and the first abutting surface 511, thereby relatively fixing the shell 1 and the limiter 24 in the axial direction to avoid relative movement between the two.

[0075] Since the outer diameter of at least two groups of bosses 51 is larger than the inner diameter of the ring 52, in order to assemble the shielding assembly 2 and the housing 1, a guide groove 522 is provided on the ring 52. The inner diameter of the guide groove 522 is larger than the outer diameter of at least two groups of bosses 51. The guide groove 522 is used to guide the boss 51 to pass through. Specifically, when assembling the shielding assembly 2 and the housing 1, the boss 51 is first aligned with the guide groove 522. When the boss 51 completely passes through the guide groove 522, the shielding assembly 2 is rotated to make the boss 51 away from the guide groove 522, and the first abutting surface 511 abuts against the second abutting surface 521.

[0076] It should be noted that the shielding assembly 2 is first assembled with the cable, and then the shielding assembly 2 is assembled into the housing 1 , and finally the anti-rotation component 3 is installed from the rear end of the housing 1 .

[0077] See also Figure 4 , Figure 6 and Figure 7 On the basis of the above embodiment, a positioning block 512 protruding toward the front end of the housing 1 is further provided on the first abutting surface 511 ; a positioning groove 523 engaged with the positioning block 512 is provided on the second abutting surface 521 .

[0078] The positioning block 512 and the positioning groove 523 play a role in rotation positioning. When the shielding assembly 2 is rotated, when the positioning block 512 is embedded in the guide groove 522, it means that the shielding assembly 2 is rotated into place.

[0079] In order to reduce the rotational friction between the positioning block 512 and the second abutting surface 521, the length of the positioning block 512 is much smaller than the length of the first abutting surface 511, and the height of the positioning block 512 protruding forward is limited; in addition, the positioning block 512 adopts a hemispherical structure, or an arc block structure, that is, there is line contact or point contact between the positioning block 512 and the second abutting surface 521.

[0080] See also Figure 7 In some embodiments, avoidance holes 244 corresponding to at least two groups of bosses 51 are circumferentially spaced apart on the outer wall of the shielding assembly 2, and each group of bosses 51 is arranged at the corresponding avoidance holes 244; a deformation hole 513 is also formed on the boss 51.

[0081] The avoidance hole 244 is used to avoid the boss 51 so that the boss 51 can be slightly displaced radially inward to avoid hard contact with the groove wall of the guide groove 522 and pass through the guide groove 522 smoothly.

[0082] The deformation hole 513 can provide axial movement space for the boss 51 and the positioning block 512 , so that the positioning block 512 can be slightly displaced axially backward when the shielding assembly 2 is rotated, further reducing the friction with the second abutting surface 521 .

[0083] In some embodiments, the anti-rotation member 3 and the shielding assembly 2 may be connected by Figure 2 , Figure 5 and Figure 8 The structure shown, see Figure 2 , Figure 5 and Figure 8 The outer wall of the shielding assembly 2 has an outer polygonal portion 211 , and the inner wall of the anti-rotation component 3 has an inner polygonal portion 31 . The inner polygonal portion 31 is matched with the outer polygonal portion 211 , and the inner polygonal portion 31 is sleeved on the outer polygonal portion 211 and limited circumferentially with the outer polygonal portion 211 .

[0084] Specifically, the outer polygonal portion 211 is located on the shielding outer cylinder 21. The outer polygonal portion 211 is formed by crimping, and when the shielding outer cylinder 21 and the shielding inner cylinder 22 are crimped, the outer polygonal portion 211 can be crimped and formed at the same time.

[0085] The inner polygonal portion 31 is sleeved on the outer polygonal portion 211 to achieve circumferential limitation of the anti-rotation component 3 and the shielding assembly 2. The outer polygonal portion 211 is easily crimped on the shielding outer cylinder 21, making the anti-rotation structure simple and having a good anti-rotation effect.

[0086] In some embodiments, the circumferential limiting structure 4 may be Figure 2 , Figure 5 and Figure 6 The structure shown, see Figure 2 , Figure 5 and Figure 6 The circumferential limiting structure 4 includes a plurality of groups of first ridges 41 and a plurality of groups of second ridges 43. The plurality of groups of first ridges 41 are evenly spaced along the circumferential direction on the inner wall of the housing 1; a limiting gap 42 is formed between each two adjacent groups of first ridges 41; and the plurality of groups of second ridges 43 are evenly spaced along the circumferential direction on the outer wall of the shielding assembly 2.

[0087] Among them, the width of the limiting gap 42 is adapted to the width of the second ridges 43, and each group of second ridges 43 is correspondingly arranged in one of the limiting gaps 42, that is, the two side surfaces of each group of second ridges 43 respectively abut against the opposite side surfaces of two adjacent first ridges 41 to limit the rotation of the anti-rotation component 3 relative to the housing 1.

[0088] By utilizing the one-to-one corresponding engagement relationship between multiple groups of second convex edges 43 and multiple limiting gaps 42, circumferential limiting is achieved, and the anti-rotation effect is good. The implementation method is simple, making the anti-rotation component 3 and the housing 1 easy to manufacture and shape.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
