DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words such as "upper" and "lower" used generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0041] It is usually necessary to connect the wires to the bus in the high-voltage box (Battery Disconnect Unit, BDU) of the battery pack so that the voltage signal of the bus can be collected through the wires. In the related art, the connection between the wires and the bus can be fixed by riveting the OT terminal or the plug-in terminal to the bus, and then connecting the OT terminal or the plug-in terminal to the wire. Among them, whether the bus is connected to the wire through the OT terminal or the plug-in terminal, it is necessary to rivet and fix it, which makes the wiring method of the bus more complicated and affects the wiring efficiency of the bus.

[0042] In order to simplify the wiring method of the bus and improve the wiring efficiency of the bus, an embodiment of the present application provides a wiring terminal.

[0043] Figure 1 This is a schematic diagram of the structure of an embodiment of a high-voltage box provided in an embodiment of the present application. Figure 1 As shown, the high-voltage box 100 includes a busbar 110, a support member 120 and a terminal 130, wherein the support member 120 is arranged opposite to the busbar 110, the terminal 130 is connected to the busbar 110, and the terminal 130 is used to connect with the wire 140, so as to electrically connect the wire 140 and the busbar 110 together, so as to collect the voltage signal of the busbar 110 through the wire 140. Among them, a connection hole 1101 is opened on one side of the busbar 110, and the terminal 130 is used to be inserted into the connection hole 1101, so as to electrically connect the terminal 130 and the busbar 110. The support member 120 is arranged opposite to one side of the busbar 110.

[0044] In some embodiments, Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, the connection terminal 130 includes a clamping portion 131, a positioning portion 132 and a wiring portion 133. The clamping portion 131 is used to be inserted into the connection hole 1101 of the busbar 110 and clamped with the connection hole 1101, so that the clamping portion 131 of the connection terminal 130 can stably maintain contact with the busbar 110 to stably electrically connect the connection terminal 130 to the busbar 110. One end of the positioning portion 132 of the connection terminal 130 is connected to the clamping portion 131, and the positioning portion 132 is used to cooperate with the support member 120 located on one side of the busbar 110 for positioning. The wiring portion 133 of the connection terminal 130 is connected to the other end of the positioning portion 132, and the wiring portion 133 is used to connect with the wire 140.

[0045] The wiring terminal 130 provided in the embodiment of the present application is clamped with the connecting hole 1101 of the bus 110 through the clamping portion 131, and is positioned and matched with the support member 120 through the positioning portion 132. It not only has a simple structure and is easy to manufacture, but also can keep the position of the wiring terminal 130 relative to the bus 110 stable, thereby achieving a stable electrical connection between the wiring terminal 130 and the bus 110. When the wiring portion 133 of the wiring terminal 130 is connected to the wire 140, the wire 140 can maintain a stable electrical connection with the bus 110, so as to accurately collect the voltage signal of the bus 110 through the wire 140.

[0046] Moreover, since the clamping portion 131 of the connection terminal 130 is inserted into the connection hole 1101 of the busbar 110, the connection terminal 130 of the busbar 110 is clamped with the connection hole 1101 of the busbar 110. Therefore, during the connection between the busbar 110 and the connection terminal 130, the positioning portion 132 of the connection terminal 130 and the support member 120 can be mutually coordinated and positioned, so that the position of the connection terminal 130 relative to the support member 120 remains stable. Then, the busbar 110 is installed, and the clamping portion 131 of the connection terminal 130 is inserted into the connection hole 1101 of the busbar 110, so that the connection between the connection terminal 130 and the busbar 110 is completed, and there is no need to further rivet the connection terminal 130, which is very convenient to operate, and can save the riveting tooling mold, which is conducive to improving the wiring efficiency of the busbar 110 and reducing the wiring cost of the busbar 110.

[0047] In some embodiments, Figure 2 , Figure 5 and Figure 7As shown, the clamping portion 131 of the terminal block 130 extends along the first direction X, and the positioning portion 132 of the terminal block 130 extends along the second direction Y, and the first direction X forms an angle with the second direction Y. Thus, after the positioning portion 132 of the terminal block 130 is positioned and matched with the support member 120, the connection hole 1101 of the busbar 110 is aligned with the clamping portion 131 of the terminal block 130, and then the busbar 110 is moved relative to the terminal block 130 and close to the terminal block 130 along the first direction X, so that the clamping portion 131 of the terminal block 130 is inserted into the connection hole 1101 of the busbar 110 and clamped with the connection hole 1101.

[0048] Moreover, since the extension direction of the clamping portion 131 of the terminal block 130 forms an angle with the extension direction of the positioning portion 132, the wiring portion 133 of the terminal block 130 and the clamping portion 131 can be relatively offset by a certain distance in the second direction Y, so as to reduce the obstruction of the wiring portion 133 by the bus 110, and even make the wiring portion 133 extend out of the edge of the bus 110, so as to facilitate the connection of the wiring portion 133 with the wire 140.

[0049] It should be noted that the angle formed by the first direction X and the second direction Y can be a right angle or an acute angle, which can be determined according to the structure and position of the terminal block 130, the support member 120 and the bus bar 110. It is only necessary to connect the clamping portion 131 of the terminal block 130 to the bus bar 110, and the wiring portion 133 of the terminal block 130 can also be connected to the wire 140.

[0050] In some embodiments, Figure 4 and Figure 7 As shown, the clamping portion 131 of the terminal block 130 can include two abutment segments 1313 extending along the first direction X, one end of the two abutment segments 1313 is respectively connected to one end of the positioning portion 132, and a deformation space 1315 is provided between the two abutment segments 1313 so that the two abutment segments 1313 can produce elastic deformation toward the deformation space 1315.

[0051] The abutting section 1313 has an abutting surface 1314 for abutting against the inner peripheral surface of the connecting hole 1101 on the side away from the deformation space 1315. In the direction in which the clamping portion 131 is away from the positioning portion 132 along the first direction X, the distance between the abutting surfaces 1314 of the two abutting sections 1313 first increases and then decreases. Therefore, when the clamping portion 131 of the connection terminal 130 is inserted into the connecting hole 1101 of the busbar 110, the abutting surfaces 1314 of the two abutting sections 1313 of the clamping portion 131 respectively abut against the inner peripheral surface of the connecting hole 1101, so that the clamping portion 131 is clamped with the connecting hole 1101 of the busbar 110.

[0052] Among them, the two abutment sections 1313 can be connected to each other at one end away from the positioning portion 132 to improve the deformation resistance of the two abutment sections 1313, so that after the clamping portion 131 of the terminal 130 is inserted into the connecting hole 1101 of the bus 110, the force between the abutment surfaces 1314 of the two abutment sections 1313 of the clamping portion 131 and the inner circumferential surface of the connecting hole 1101 is greater, so as to further improve the connection stability between the clamping portion 131 and the bus 110.

[0053] In addition, in the direction where the clamping portion 131 moves away from the positioning portion 132 along the first direction X, the width of the deformation space 1315 in the distribution direction of the two abutting segments 1313 (that is, the distance between the two abutting segments 1313) can first increase and then decrease, or remain unchanged, as long as the two abutting segments 1313 of the clamping portion 131 can bend and deform toward the deformation space 1315.

[0054] In some embodiments, the middle parts of the two abutting sections 1313 of the clamping portion 131 can be bent in a direction away from each other, so that the distance between the abutting surfaces 1314 of the two abutting sections 1313 first increases and then decreases in a direction away from the positioning portion 132. In addition, the two abutting sections 1313 of the clamping portion 131 are made more compatible with the connecting hole 1101 with a circular cross section, so as to improve the clamping stability of the two abutting sections 1313 of the clamping portion 131 and the connecting hole 1101 with a circular cross section.

[0055] In other embodiments, Figure 6 , Figure 8 and Fig. 9 As shown, the clamping portion 131 of the connection terminal 130 may include two abutting protrusions 1311, and the protruding directions of the two abutting protrusions 1311 respectively form an angle with the first direction X. When the clamping portion 131 of the connection terminal 130 is inserted into the connection hole 1101 of the busbar 110, one side of the two abutting protrusions 1311 along the protruding direction can respectively abut against the inner circumferential surface of the connection hole 1101, so that the clamping portion 131 is clamped with the connection hole 1101 of the busbar 110.

[0056] Among them, the clamping part 131 is provided with a through hole 1312, and the through hole 1312 penetrates the clamping part 131 along the second direction Y. Two abutting protrusions 1311 extend along the first direction X, and the two ends of each abutting protrusion 1311 along the first direction X are respectively connected to the edge of the through hole 1312. The two abutting protrusions 1311 are distributed in sequence along the third direction Z. The two abutting protrusions 1311 of the clamping part 131 protrude along the second direction Y. The protruding directions of the two abutting protrusions 1311 are opposite. Thereby, the two abutting protrusions 1311 of the clamping part 131 are more adapted to the connecting hole 1101 with a square cross section, so as to improve the clamping stability of the clamping part 131 and the connecting hole 1101 with a square cross section. Moreover, the clamping part 131 can be stamped to form two abutting protrusions 1311, so that the processing of the clamping part 131 is very convenient.

[0057] Of course, the clamping portion 131 of the connection terminal 130 provided in the embodiment of the present application may also be other structures that can be inserted into the connection hole 1101 of the bus bar 110 and clamped with the connection hole 1101 , which will not be described in detail here.

[0058] As 7 to Fig. 9 As shown, the positioning portion 132 includes a connecting section 1321, one end of which is connected to the clamping portion 131, and the other end of the connecting section 1321 is connected to the wiring portion 133. The connecting section 1321 can be extended along the second direction Y. The connecting section 1321 includes a first end and a second end opposite to each other, and the first end and the second end are distributed at both ends of the connecting section 1321 along the extension direction of the connecting section 1321. The first end of the connecting section 1321 is connected to the clamping portion 131, and the second end of the connecting section 1321 is connected to the wiring portion 133, so that the positioning portion 132 is connected to the clamping portion 131 and the wiring portion 133.

[0059] In some embodiments, Figure 3 , Figure 6 and Figure 8 As shown, the positioning portion 132 of the connection terminal 130 may include a positioning protrusion 1322, which is protruding from one side of the connecting section 1321 along the third direction Z, and the third direction Z forms an angle with the second direction Y. Thus, when the positioning portion 132 of the connection terminal 130 cooperates with the support member 120 for positioning, the cooperation between the positioning protrusion 1322 and the support member 120 can make the cooperation between the positioning portion 132 and the support member 120 more stable, which is conducive to improving the stability of the relative position of the connection terminal 130 and the support member 120.

[0060] It should be noted that the angle formed by the third direction Z and the second direction Y can be a right angle or an acute angle, as long as the positioning protrusion 1322 cooperates with the support member 120 to further improve the stability of the connection terminal 130 relative to the support member 120.

[0061] The connection section 1321 may be provided with positioning protrusions 1322 on both sides along the third direction Z. The two positioning protrusions 1322 cooperate with the support member 120 to further improve the cooperation stability between the positioning portion 132 and the support member 120 .

[0062] In some embodiments, the support member 120 may include a mounting position 121, and the positioning portion 132 of the wiring terminal 130 may be installed at the mounting position 121 of the support member 120, so that the mounting position 121 of the support member 120 and the positioning portion 132 of the wiring terminal 130 are mutually matched and positioned. Among them, the mounting position 121 of the support member 120 may include an adapting groove that is matched with the shape of the positioning portion 132 of the wiring terminal 130, and the positioning portion 132 is installed in the adapting groove of the support member 120, so that the positioning portion 132 and the support member 120 are matched and positioned. Alternatively, the positioning portion 132 may also include an adapting groove that is matched with the mounting position 121 of the support member 120, and the mounting position 121 of the support member 120 is inserted into the adapting groove of the positioning portion 132, so that the positioning portion 132 and the support member 120 are matched and positioned.

[0063] In some embodiments, Figure 5 and Figure 7 As shown, the mounting position 121 of the support member 120 may include a positioning groove 1211, and at least a portion of the positioning protrusion 1322 of the positioning portion 132 of the terminal block 130 may be located in the positioning groove 1211. The support member 120 cooperates with the positioning protrusion 1322 through the positioning groove 1211, thereby improving the positioning effect of the positioning portion 132. When the positioning portion 132 includes two positioning protrusions 1322, at least a portion of the two positioning protrusions 1322 of the positioning portion 132 may be located in the positioning groove 1211.

[0064] In other embodiments, Figure 6 , Figure 8 and Fig. 9 As shown, the positioning portion 132 includes an anti-detachment portion 1323 connected to the connecting section 1321, and the anti-detachment portion 1323 and the clamping portion 131 respectively protrude from opposite sides of the connecting section 1321. Therefore, when the positioning portion 132 of the terminal block 130 is positioned with the support member 120, the movement of the positioning portion 132 relative to the support member 120 in the second direction Y can be limited by the cooperation of the anti-detachment portion 1323 and the support member 120, so as to further improve the cooperation stability between the positioning portion 132 and the support member 120.

[0065] One end of the anti-detachment portion 1323 can be connected to the connecting section 1321, and the anti-detachment portion 1323 extends in the direction from the first end to the second end of the connecting section 1321, and is inclined relative to the second direction Y. Thus, one end of the anti-detachment portion 1323 in the direction from the first end to the second end of the connecting section 1321 can abut against the support member 120 to limit the movement of the stopper relative to the support member 120 in the direction from the first end to the second end.

[0066] Specifically, the connecting section 1321 is provided with an avoidance hole 1324, and the avoidance hole 1324 penetrates the connecting section 1321 along the first direction X. On a projection plane perpendicular to the first direction X, the orthographic projection of the anti-slip portion 1323 is located within the orthographic projection range of the avoidance hole 1324. Thus, the connecting section 1321 can be stamped to form the anti-slip portion 1323, making the processing method of the anti-slip portion 1323 more convenient.

[0067] The mounting position 121 of the support member 120 may include an anti-slip groove 1212, and at least a portion of the anti-slip portion 1323 of the positioning portion 132 of the terminal block 130 may be located in the anti-slip groove 1212. Thus, the movement of the positioning portion 132 relative to the support member 120 in the second direction Y can be limited by the anti-slip portion 1323 abutting against the inner surface of the anti-slip groove 1212.

[0068] Specifically, the positioning groove 1211 is adapted to the shape of the connecting section 1321 and the two positioning protrusions 1322 of the positioning portion 132. At least a portion of the connecting section 1321 and the two positioning protrusions 1322 of the positioning portion 132 are installed in the positioning groove 1211. The anti-slip groove 1212 is provided on the bottom surface of the positioning groove 1211. One end of the anti-slip portion 1323 along the direction from the first end to the second end of the connecting section 1321 is located in the anti-slip groove 1212, and one end of the anti-slip portion 1323 along the direction from the first end to the second end of the connecting section 1321 is used to abut against the inner circumferential surface of the anti-slip groove 1212 to limit the positioning member from moving relative to the support member 120 along the direction from the first end to the second end of the connecting section 1321.

[0069] It should be noted that the positioning portion 132 of the terminal block 130 can include both the positioning protrusion 1322 and the anti-detachment portion 1323, or the positioning portion 132 of the terminal block 130 can include only one of the positioning protrusion 1322 and the anti-detachment portion 1323. Of course, the former can further improve the stability of the positioning portion 132 of the terminal block 130 after being positioned in coordination with the support member 120.

[0070] In some embodiments, the support member 120 may be a plastic housing for accommodating electrical components in the high-voltage box 100. The busbar 110 is mounted on the support member 120 and is electrically connected to the electrical components in the support member 120.

[0071] Of course, the support member 120 can also be other insulating components arranged opposite to one side of the bus 110, which can be determined according to the structure inside the high-voltage box 100. It only needs to form an installation position 121 on the support member 120 for cooperating with the positioning portion 132 of the terminal block 130.

[0072] In some embodiments, the material of the clamping portion 131 of the terminal block 130 may be phosphor bronze or other conductive materials with higher yield strength, so that the clamping portion 131 of the terminal block 130 can generate a greater force between the inner circumferential surface of the connecting hole 1101 of the bus bar 110, thereby improving the clamping stability between the clamping portion 131 and the connecting hole 1101 of the bus bar 110.

[0073] The clamping portion 131 , the positioning portion 132 and the wiring portion 133 of the wiring terminal 130 may be provided in one piece or in separate pieces. Of course, the former can make the structural strength of the wiring terminal 130 higher and the manufacturing is more convenient.

[0074] In some embodiments, Figures 7 to 9 As shown, the wiring portion 133 of the terminal block 130 may include a wiring groove 1331. By placing one end of the wire 140 in the wiring groove 1331 and squeezing the wiring portion 133 to deform the wiring groove 1331, the wiring portion 133 is pressed against one end of the wire 140 to achieve connection between the wiring portion 133 and the wire 140.

[0075] Of course, the connection portion 133 of the connection terminal 130 may also be other structures that can be connected to the wire 140, which is not limited here.

[0076] The extension direction of the connection portion 133 of the connection terminal 130 and the extension direction of the positioning portion 132 may be parallel or may be at a certain angle. Figures 7 to 9 As shown, the connection portion 133 of the connection terminal 130 extends along the second direction Y. Alternatively, the connection portion 133 of the connection terminal 130 may extend along the first direction X, and the connection portion 133 and the clamping portion 131 may be located on the same side or opposite sides of the positioning portion 132 .

When installing the busbar 110, the clamping portion 131 of the terminal block 130 is inserted into the connecting hole 1101 of the busbar 110 to complete the connection between the terminal block 130 and the busbar 110. There is no need to further rivet the terminal block 130, which is very convenient to operate and can save the riveting tooling mold, which is beneficial to improving the wiring efficiency of the busbar 110 and reducing the wiring cost of the busbar 110, thereby improving the production efficiency of the high-voltage box 100 and reducing the production cost of the high-voltage box 100.

[0080] In some embodiments, the positioning portion 132 of the connection terminal 130 can be clamped between the busbar 110 and the support member 120. By clamping the positioning portion 132 between the busbar 110 and the support member 120, the position stability of the connection terminal 130 relative to the busbar 110 can be further improved to prevent the connection terminal 130 from shaking relative to the busbar 110.

[0081] In some embodiments, the interference between the clamping portion 131 of the terminal 130 and the connecting hole 1101 of the busbar 110 is greater than or equal to 0.2 mm, so as to increase the force between the clamping portion 131 and the inner circumference of the connecting hole 1101, thereby improving the clamping effect between the clamping portion 131 and the connecting hole 1101. The interference between the clamping portion 131 of the terminal 130 and the connecting hole 1101 of the busbar 110 can be 0.25 mm, 0.3 mm, etc., which can be determined according to the structure of the clamping portion 131 and the connecting hole 1101.

[0082] In addition, the interference between the clamping portion 131 and the connection hole 1101 can be less than or equal to 0.4 mm to avoid excessive interference between the clamping portion 131 and the connection hole 1101, which may result in the clamping portion 131 of the connection terminal 130 being unable to be smoothly inserted into the connection hole 1101 of the busbar 110. The interference between the clamping portion 131 of the connection terminal 130 and the connection hole 1101 of the busbar 110 can be 0.35 mm, 0.32 mm, 0.27 mm, etc., depending on the structure of the clamping portion 131 and the connection hole 1101.

[0083] In some preferred embodiments, the interference between the clamping portion 131 of the terminal block 130 and the connecting hole 1101 of the bus bar 110 can be greater than or equal to 0.2 mm and less than or equal to 0.4 mm, so that the clamping portion 131 of the terminal block 130 and the connecting hole 1101 of the bus bar 110 can be stably clamped together, and the clamping portion 131 of the terminal block 130 can be easily inserted into the connecting hole 1101 of the bus bar 110.
