They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0050] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0051] Example 1

[0052] Please refer to Figure 1 、 Figure 2, an embodiment of the utility model provides a high-voltage connection housing, wherein the front end 12 and the rear end 11 of the high-voltage connection housing 1 are connected in a first direction for inserting and connecting a conductor or a conductor assembly 3;

[0053] A connector 2 is provided on one side of the high-voltage connection housing 1 for connecting a cable 41 , and the connector 2 extends along the second direction;

[0054] The preset angle A formed between the first direction and the second direction is 180°>A>90°.

[0055] Specifically, the high-voltage connection housing 1 refers to the housing used to protect and secure high-voltage electrical connection components in a high-voltage connector. The high-voltage gas connection components include the conductor or conductor assembly 3 in the connector and the power cable 41 or cable 41 assembly. The high-voltage connection housing 1 is usually made of an insulating material that can withstand high-voltage current and has good insulation properties to ensure safety.

[0056] The first direction refers to the length direction of the high-voltage connection housing 1 , that is, the direction along which the conductor or conductor assembly 3 is inserted.

[0057] The connector 2 is a component used to secure the cable 41 and connect the cable 41 to the internal circuit (conductor assembly 3) of the high-voltage connection housing 1. In this embodiment, one end of the connector 2 is connected to the bottom of the high-voltage connection housing 1, and the other end points in the second direction.

[0058] The connecting member 2 is hollow, and its internal space is connected to the space inside the high-voltage connection housing 1. When using the high-voltage connector provided in this embodiment, the cable 41 is inserted into the connecting member 2 along the second direction and connected to the conductor or conductor assembly 3 in the part of the high-voltage connection housing 1.

[0059] The angle A between the first direction and the second direction is 180°>A>90°, which makes the layout between the connector 2 and the high-voltage connection housing 1 more reasonable, does not affect the normal use of the high-voltage connection housing 1, ensures that the relative position between the connector 2 and the high-voltage connection housing 1 is fixed, and prevents loosening or breakage due to external forces.

[0060] At the same time, the connector 2 and the high-voltage connection housing 1 are integrated, and the preset angle A between the first direction and the second direction is adjusted according to the usage scenario of the high-voltage connector and its usage space size to adapt to meet different terminal space size requirements.

[0061] The technical solution provided in this embodiment changes the external dimensions and parts layout of the high-voltage connector by setting the plug-in direction of the conductor / conductor assembly 3 and the cable 41 on the high-voltage connection housing 1, thereby realizing flexible use of the high-voltage connector in a limited space. The connection design of the preset angle formed by the connector 2 in the second direction and the high-voltage connection housing 1 in the first direction allows the connector to be installed in a limited space without the need for an additional large area of ​​space to support its installation, thereby greatly facilitating the internal layout design of the terminal product and reducing the problem of large space occupation caused by space limitations. Due to the preset angle of greater than 90 degrees and less than 180 degrees formed between the connector 2 and the housing, the connector can better utilize the space inside the terminal product without changing its function, thereby achieving better space utilization. The high-voltage connection housing 1 provided by the utility model not only solves the problems of installation position and space limitations of traditional connectors, but also improves the flexibility and compatibility of the connector in practical applications, providing more possibilities for the design of terminal products.

[0062] In one embodiment, the preset angle includes 125 degrees.

[0063] Specifically, the preset angle A is 125 degrees, so that the high-voltage connector at the preset angle A can fit the space design of the car.

[0064] In one embodiment, the preset angle A also includes 135 degrees.

[0065] In one embodiment, the preset angle A also includes 120 degrees.

[0066] In one embodiment, if Figure 1 As shown, the high-voltage connection housing 1 also includes: an upper cover shell 13 and an upper cover seal 131 arranged at the rear end 11 of the high-voltage connection housing 1, and an annular groove 132 is provided on the lower periphery of the upper cover shell 13, and the upper cover seal 131 is embedded in the annular groove 132.

[0067] Specifically, such as Figure 1 、 Figure 2 As shown, a pair of first bearing supports 15 are symmetrically arranged above the rear end 11 of the high-voltage connection housing 1, and the first bearing supports 15 are respectively provided with axial holes for the shaft 16 to pass through. The upper cover shell 13 includes a pair of second bearing supports 133, and the second bearing supports 133 are respectively provided with axial holes for the shaft 16 to pass through. During installation, the second bearing supports 133 are placed between the first bearing supports 15, and the upper cover shell 13 is connected to the high-voltage connection housing 1 by a shaft 16 passing through the axial holes on the first bearing supports 15 and the second bearing supports 133 in sequence.

[0068] A first flange 134 is provided on the side of the upper cover shell 13 on the side where the second bearing bracket 133 is installed. Correspondingly, a second flange 17 is provided below the rear end 11 of the high-voltage connecting shell 1, and screw holes are respectively provided on the first flange 134 and the second flange 17.

[0069] After the high-voltage connector is installed, the upper cover housing can be rotated downward around the shaft 16 through the connection between the shaft 16 and the second bearing bracket 133, and the upper cover housing is covered with the rear end 11 of the high-voltage connector housing 1. The third bolt fixing member 135 is passed through the screw holes on the first flange 134 and the second flange 17 to fix the position of the upper cover housing and the high-voltage connector housing 1. The rear end 11 of the high-voltage connector housing 1 is closed.

[0070] In one embodiment, if Figure 1 、 Figure 2 As shown, the outer side of the front end 12 of the high-voltage connection housing 1 extends outward perpendicular to the length direction of the high-voltage connection housing to form a mounting portion 18, and fixing holes 19 are provided around the mounting portion 18 for the second fixing member 6 to pass through the fixing holes 19 to fix the high-voltage connector to other parts to prevent the high-voltage connector from shaking and affecting electrical transmission.

[0071] In one embodiment, if Figure 1 、 Figure 2 As shown, a grid member 14 is arranged inside the high-voltage connection shell 1 along the first direction, and the grid member 14 includes a first vertical plate 141, a second vertical plate 142 and a horizontal plate 143. The first vertical plate 141 and the second vertical plate 142 are spaced a certain distance apart, and the upper and lower ends of the vertical plate are respectively connected to the upper and lower inner walls of the high-voltage connection shell 1, and the horizontal plate 143 is arranged between the first vertical plate 141 and the second vertical plate 142 and connected to the two vertical plates.

[0072] Specifically, when multiple groups of conductor components 3 are provided in the high-voltage connector, the conductor components 3 inserted between the high-voltage connectors need to be isolated to avoid being affected by adjacent conductor components 3 during the electrical connection process, thereby causing the circuit to burn or other situations to occur, resulting in the high-voltage connector being unable to be used normally.

[0073] Example 2

[0074] like Figure 3 and 4 As shown, based on the high-voltage connection housing 1 described in the above embodiment 1, this embodiment provides a high-voltage connector, the high-voltage connector comprising:

[0075] Any one of the high-voltage connection housings 1 provided in the above embodiment 1;

[0076] A conductor assembly 3 , one end of which is inserted into the high-voltage connection housing 1 from the front end 12 in the first direction, for electrically connecting to a cable 41 inserted into the connector 2 in the second direction.

[0077] Specifically, the conductor assembly 3 is used to transmit high voltage current, and the cable 41 is electrically connected to the conductor assembly to provide current thereto.

[0078] One end of the conductor assembly 3 is inserted into the front end 12 of the high-voltage connection housing 1 along a first direction, and the cable 41 is inserted into the connector 2 along a second direction. The conductor assembly 3 and the cable 41 are electrically connected in the high-voltage connection housing 1.

[0079] In this embodiment, the high-voltage connection housing 1 is provided with a preset angle A between the first direction and the second direction, so that the layout of the cable 41 and the conductor assembly 3 is more reasonable, thereby avoiding the cable 41 from falling off or being damaged due to excessive force, and improving the reliability of the connection; at the same time, the cable 41 is installed in the second direction so that the cable 41 is led out from the side, which facilitates wiring and maintenance, optimizes the layout of the cable 41, and avoids conflict with other components.

[0080] In one embodiment, if Figure 5 and Figure 6 As shown, the conductor assembly 3 includes a conductor terminal 31 and an insulating member 32 sleeved on the conductor terminal 31;

[0081] One end of the conductor terminal 31 inserted into the insulating member 32 is bent and extended to form a first fixing portion 311;

[0082] The insulating member 32 is built into the high-voltage connection housing 1 , and the other end is arranged in multiple stages in the first direction, each stage being used to abut against the inner wall of the high-voltage connection housing 1 to fix the position of the insulating member 32 in the high-voltage connection housing.

[0083] Specifically, one end of the conductor terminal 31 inserted into the insulating member is bent 90 degrees and extends upward to form a first fixing portion 311, which is used to electrically connect to the wiring harness assembly 4 in the high-voltage connection housing 1; the other end is used to electrically connect to the part structure outside the high-voltage connector, and this end is enlarged to increase the contact area with the part to avoid disconnection of the electrical connection between the conductor terminal 31 and the part.

[0084] The insulating member 32 gradually tapers inwardly in the first direction, with the innermost layer closely fitting against the surface of the conductor terminal 31, thereby securing the conductor terminal 31. Furthermore, the multi-level arrangement of the insulating member ensures that one end of the insulating member meets the dimensions required for connection with the high-voltage connection housing 1, while the other end meets the dimensions required for the conductor terminal 31. This also avoids the problem of excessive weight and material consumption caused by the insulating member being too large.

[0085] In one embodiment, if Figure 6 、 Figure 7 As shown, the conductor assembly 3 further includes a first sealing member 33 and a retaining member 34;

[0086] The first sealing member 33 is sleeved on the annular structure 121 in the high-voltage connection housing 1 ; the insulating member 32 passes through the channel of the annular structure 121 ; and the retaining member 34 is built between the annular structure 121 and the insulating member 32 .

[0087] Specifically, such as Figure 8 As shown, a plurality of snap-in grooves 323 are provided on the outer wall of the first stage of the insulating member 32 along the first direction, and the same number of snap-in members 341 are provided on the corresponding retaining member in the first direction. During installation, the snap-in grooves 323 are snap-fitted and fixed one by one with the snap-in members 341.

[0088] A clip pin extends outward from the outside of the clip, which is used to engage with the clip portion on the inner wall of the high-voltage connection housing. At the same time, the end of the retaining member away from the clip pin 342 is larger than the size of the annular structure. The larger top 343 and the clip pin secure the retaining member within the annular structure of the high-voltage housing, preventing the retaining member from shaking or sliding out of the high-voltage connection housing. Finally, the bottom of the clip pin abuts against the stepped structure of the insulating member, preventing the insulating member from sliding or sliding out of the high-voltage connection housing, ensuring the stability of the connection.

[0089] The insulating member is provided with an abutting protrusion 324 for abutting against the top 343 , so as to fix the positions of the insulating member and the retaining member and prevent the retaining member from sliding on the insulating member.

[0090] The first sealing member 33 is sleeved on the annular structure 121, and its two ends are respectively in contact with the retaining member and the high-voltage connection housing. The first sealing member 33 is fixedly sleeved on the annular structure to improve the sealing performance of the connector and prevent moisture, dust, etc. from entering the interior of the connector.

[0091] In one embodiment, if Figure 16As shown, the insulating member includes a first insulating tube 321 and a second insulating tube 322 , and the conductor terminal 31 is inserted into the first insulating tube 321 in the first direction; the second insulating tube 322 is built into the connecting member.

[0092] Specifically, the length of the first insulating tube is oriented in a first direction within the high-voltage connector housing, while the length of the second insulating tube is oriented within the connector, parallel to the second direction. A retaining member prevents the insulating member from slipping out of the front end, and the second insulating tube is internally positioned within the connector, preventing it from slipping out of the rear end. This ensures that the insulating tubes and the high-voltage connector housing are securely fixed.

[0093] Example 3

[0094] Please refer to Figures 10-16 Based on the high-voltage connector of the above-mentioned embodiment 2, this embodiment provides an electrical connection device for use in electric vehicles, mainly used to connect the battery pack with the motor, inverter, charging system and other high-voltage electrical components to ensure the reliable transmission of large currents; the device includes at least any one of the high-voltage connectors provided in the above-mentioned embodiment 2, and a wiring harness assembly 4;

[0095] The wiring harness assembly 4 includes a cable 41 and a first shielding component 42, a second shielding component 43, a second sealing component 45, and a tail cover body 46 that are sequentially sleeved on the cable 41. The first shielding component 42 is built into the second shielding component 43, and a sealing baffle 44 is provided between the second shielding component 43 and the second sealing component 45.

[0096] Specifically, the tail cover body 46 is a hollow column structure with one end fully open. A U-shaped recess 461 is provided on one side of the tail cover body 46 , and two windows 462 are symmetrically provided on the side walls on both sides of the U-shaped recess 461 .

[0097] The inner wall size of the tail cover body 46 is slightly larger than the outer wall size of the connector 2. The high-voltage connection housing 1 also includes: a protrusion 21 is symmetrically arranged on the outside of the connector 2. When the wiring harness assembly 4 is inserted into the connector 2, the tail cover body 46 is sleeved on the outside of the connector 2, and the protrusion 21 is buckled with the window 462 to fix the position between the wiring harness assembly 4 and the connector 2.

[0098] The second shielding member 43 is designed with one end larger than the other, and the larger end is recessed to form a mounting slot for the first shielding member 42. The second shielding member 43 is used to prevent external electromagnetic interference from affecting the signal transmission within the cable 41. The second shielding member 43 effectively reduces electromagnetic interference, ensuring the stability and reliability of signal transmission within the cable 41. The first shielding member 42 prevents internal electromagnetic interference from external interference. The combination of these two layers significantly enhances the electromagnetic shielding effectiveness of the cable 41, improving the quality and stability of signal transmission.

[0099] During installation, the first shielding member 42, the second shielding member 43, and the second sealing member 45 are completely built into the connector 2, and the tail cover body 46 and the connector 2 are buckled to form a first layer of sealing between the wiring harness assembly 4 and the connector 2. The sealing baffle 44 is arranged between the second shielding member 43 and the second sealing member 45, so that the second sealing member 45 and the sealing baffle 44 located between the second shielding member 43 and the tail cover body 46 form a second layer of sealing between the wiring harness assembly 4 and the connector 2.

[0100] In one embodiment, if Figure 10 As shown, the wiring harness assembly 4 further includes a connecting terminal 47, and the connecting terminal 47 includes a connecting portion 471 and a second fixing portion 472; the connecting portion 471 extends along a predetermined angle to form the second fixing portion 472 for fixing the connecting terminal 47 at a predetermined position;

[0101] A connecting plate 411 is provided at one end of the cable 41 inserted into the connector 2 , the connecting portion 471 is fitted and connected to the connecting plate 411 , and the second fixing portion 472 is provided with a through hole;

[0102] The high-voltage connector further includes a first fixing member 5 , which passes through the through hole from the rear end 11 of the high-voltage connection housing 1 and is connected and fixed to the first fixing portion 311 .

[0103] Specifically, the connecting portion 471 and the connecting plate 411 are preferably welded to ensure electrical continuity. A predetermined angle B exists between the connecting portion 471 and the second fixing portion 472, where 90° < B < 180°. This predetermined angle ensures that the second fixing portion 311 and the first fixing portion 311 mate with each other when the connecting terminal 47 is electrically connected to the conductor terminal 31 within the high-voltage connection housing.

[0104] Preferably, the first fixing portion 311 and the second fixing portion 472 are respectively provided with a through hole, and a nut 312 is riveted on the position of the through hole on the side of the first fixing portion 311 away from the second fixing portion 472. During installation, the conductor assembly 3 is first inserted from the front end 12 of the high-voltage connection shell 1 in the first direction and preliminarily fixed through the insulating member and the annular structure 121, and then the wiring harness assembly 4 is inserted from the connector 2 into the high-voltage connection shell 1. The first fixing portion 311 and the second fixing portion 472 are face to face or arranged relative to each other at a close distance, and enter from the rear end 11 of the high-voltage connection shell 1 through the first fixing member 5 or a screw, and pass through the through holes on the first fixing portion and the second fixing portion 472 in turn, and are fixed with the nut 312 riveted on the first fixing portion 311, so as to realize the electrical connection between the conductor assembly 3 and the wiring harness assembly 4.

[0105] In this embodiment, the connection portion 471 and the second fixing portion 472 of the connection terminal 47 are arranged at a predetermined angle, so that the wiring harness assembly 4 and the conductor assembly 3 inserted into the high-voltage connection housing 1 in the second direction can be smoothly electrically connected. The second fixing portion 472 and the first fixing portion 311 are connected and fixed by the first fixing member 5 or the screw and nut 312, so that the connection terminal 47 can be firmly fixed in a predetermined position, avoiding loosening or falling off during use, thereby improving the stability of the connection. The fitting connection between the connection portion 471 and the connecting plate 411 ensures the continuity and stability of current transmission and improves electrical performance.
