[0031] In the related art, the high-voltage wire harness of a new energy vehicle is usually two in a group, one positive wire and the other negative wire. When arranging the high-voltage wire harness, sometimes it needs to be divided, that is, one main wire is divided into multiple branch wires. However, the conventional wire dividing box usually adopts wire harness flat arrangement, that is, each branch wire port on the wire dividing box is arranged in a single row. This arrangement will result in a larger volume of the wire dividing box, thus requiring a larger arrangement space.

[0032] In view of the problems in the prior art, the utility model provides a distribution box and a vehicle.

Among them, the first side surface 111 and the second side surface 112 can be arranged adjacently, can be arranged oppositely, and for other polyhedral distribution boxes, can also be arranged at intervals without being adjacent or opposite, for example, Figure 1 and Figure 2 the shell 1 is in a cuboid structure, the first side surface 111 and the second side surface 112 of the shell 1 are an example of two side surfaces arranged oppositely on the shell 1, and an example that two wire inlet interfaces 2 are arranged on the first side surface 111 and four wire outlet interfaces 3 are arranged on the second side surface 112 and distributed in two rows and two columns is also given.

[0035] The distribution box in the embodiment can connect one end of one wire bundle 900 to the wire inlet interface 2 and one end of multiple other wire bundles 900 to the multiple wire outlet interfaces 3 on the second side 112 of the shell 1, so as to realize the connection of one main wire and multiple branch wires. Meanwhile, the multiple wire outlet interfaces 3 are arranged in multiple rows and columns on the second side 112, so that the distribution of the wire outlet interfaces 3 on the second side 112 is more uniform, the size of the second side 112 in one dimension is prevented from being too large, the volume and the occupied space of the distribution box in the dimension are prevented from being large, the requirement of the distribution box for the installation space is reduced, the distribution is facilitated, and the multiple wire bundles 900 connected to the wire outlet interfaces 3 of the distribution box can be arranged in multiple rows and columns instead of being arranged flatly, so that the wire bundles 900 can be arranged more compactly and the wiring space is saved.

[0036] Optionally, in combination with Figure 2 As shown in the figure, the multiple wire outlet interfaces 3 include a first group of wire outlet interfaces and a second group of wire outlet interfaces arranged along a first direction, the first group of wire outlet interfaces and the second group of wire outlet interfaces each include at least two wire outlet interfaces 3 arranged along a second direction, and the wire outlet interfaces 3 in the first group of wire outlet interfaces and the wire outlet interfaces 3 in the second group of wire outlet interfaces are arranged one by one, wherein the first direction and the second direction are perpendicular to each other and parallel to the second side 112 respectively.

[0037] The central axis of the wire outlet interface 3 in the first group of wire outlet interfaces is perpendicular to the second side 112, the central axis of the wire outlet interface 3 in the second group of wire outlet interfaces is arranged obliquely relative to the second side 112, and the distance between the wire outlet interface 3 in the first group of wire outlet interfaces and the corresponding wire outlet interface 3 in the second group of wire outlet interfaces increases along the direction from the end of the wire outlet interface 3 connected to the shell 1 to the end away from the shell 1.

[0038] It should be noted that the first direction refers to Figure 1 the X-axis direction, i.e. the front-rear direction, and the second direction refers to Figure 1 the Z-axis direction, i.e. the up-down direction, which is also the vertical direction.

[0039] Specifically, the first side 111 and the second side 112 of the shell 1 are vertical planes, wherein the central axis of the incoming line interface 2 is perpendicular to the first side 111, and the central axis of the outgoing line interface 3 in the first group of outgoing line interfaces is perpendicular to the second side 112, that is, the incoming line interface 2 and the outgoing line interface 3 in the first group of outgoing line interfaces are both horizontally arranged. At the same time, the distance between the outgoing line interface 3 in the first group of outgoing line interfaces and the corresponding outgoing line interface 3 in the second group of outgoing line interfaces increases from the end of the outgoing line interface 3 connected to the shell 1 to the end away from the shell 1, that is, the outgoing line interface 3 in the second group of outgoing line interfaces is inclined relative to the outgoing line interface 3 in the first group of outgoing line interfaces, and the distance between them gradually increases away from the shell 1, for example, the outgoing line interface 3 in the first group of outgoing line interfaces is horizontally arranged, and the outgoing line interface 3 in the second group of outgoing line interfaces is inclined upward or downward. In addition, the number of the first group of outgoing line interfaces and the second group of outgoing line interfaces can be one or more, and one first group of outgoing line interfaces and one second group of outgoing line interfaces form a row of outgoing line interfaces 3, for example Figure 2 As shown, one first group of outgoing line interfaces and one second group of outgoing line interfaces can be arranged to form two rows of multiple columns of outgoing line interfaces 3, and for example, two first groups of outgoing line interfaces and one second group of outgoing line interfaces can be arranged to form three rows of multiple columns of outgoing line interfaces 3, and for example, one or more first groups of outgoing line interfaces and two second groups of outgoing line interfaces can be arranged, all the first groups of outgoing line interfaces are arranged in sequence, and the two second groups of outgoing line interfaces can be located at both ends of the arrangement direction of all the first groups of outgoing line interfaces, so that the outgoing line interface 3 in each second group of outgoing line interfaces can be inclined toward the direction away from all the first groups of outgoing line interfaces.

[0040] In this optional embodiment, by arranging the central axis of the outgoing line interface 3 in the first group of outgoing line interfaces to be perpendicular to the second side 112, the central axis of the outgoing line interface 3 in the second group of outgoing line interfaces is inclined relative to the second side 112, and the distance between the outgoing line interface 3 in the first group of outgoing line interfaces and the corresponding outgoing line interface 3 in the second group of outgoing line interfaces is arranged to increase from the end of the outgoing line interface 3 connected to the shell 1 to the end away from the shell 1, so that the distance between the wiring end (the end away from the shell 1) of the outgoing line interface 3 in the first group of outgoing line interfaces and the wiring end (the end away from the shell 1) of the outgoing line interface 3 in the second group of outgoing line interfaces is relatively large. Compared with arranging the outgoing line interfaces 3 in each row to be horizontally arranged, the installation space of the wire harness 900 at the outgoing line interface 3 can be increased, thereby facilitating the connection of the wire harness 900 and improving the wiring efficiency.

[0041] Optionally, in combination with Figure 3 and Figure 6As shown, the incoming wire interface 2 and the outgoing wire interface 3 each include a sleeve 71, a terminal 72 and a sealing body 73, the sleeve 71 is connected to the shell 1, one end of the terminal 72 is located in the sleeve 71 and is used to be crimped with the wire harness 900, the other end is located in the shell 1, the sealing body 73 is embedded in the sleeve 71 and is located on the side of the terminal 72 away from the shell 1, and the sealing body 73 is used to be sleeved on the wire harness 900, and the terminals 72 of the plurality of outgoing wire interfaces 3 are respectively connected with the terminal 72 of the incoming wire interface 2.

[0042] In the alternative embodiment, the incoming wire interface 2 and the outgoing wire interface 3 are the same or similar in structure and each is composed of a sleeve 71, a terminal 72 and a sealing body 73, wherein the sleeve 71 is usually made of metal material and is integrally connected with the shell 1, the sleeve 71 of the incoming wire interface 2 is connected to the first side surface 111 of the shell 1, and the sleeve 71 of the outgoing wire interface 3 is connected to the second side surface 112 of the shell 1, and the sleeve 71 of the incoming wire interface 2 and the sleeve 71 of the outgoing wire interface 3 in the first group of outgoing wire interfaces are horizontally arranged, and the sleeve 71 of the outgoing wire interface 3 in the second group of outgoing wire interfaces is arranged obliquely upward or downward. The terminal 72 is arranged in the sleeve 71 and extends into the shell 1, and by crimping one end of the wire harness 900 with the terminal 72, the wire harness 900 is fixed at the wire port of the distribution box. The sealing body 73 is arranged in the sleeve 71 and is located on the side of the terminal 72 away from the shell 1. During assembly, the wire harness 900 is passed through the sealing body 73 and crimped into the terminal 72, so that the end of the wire harness 900 is sealed by the sealing body 73, and the sealing body 73 is embedded in the sleeve 71 by interference fit with the sleeve 71, so as to ensure firm installation of the sealing body 73. Moreover, by connecting the terminals 72 of the plurality of outgoing wire interfaces 3 and the terminal 72 of the incoming wire interface 2 inside the shell 1, the main wire connected at the incoming wire interface 2 is in conduction with the branch wire connected at the outgoing wire interface 3.

[0043] Optionally, in combination with Figure 3 and Figure 6 As shown, the incoming wire interface 2 and the outgoing wire interface 3 further include an end cover 74, the end cover 74 is arranged at the end of the sleeve 71 away from the shell 1 and is clamped with the sleeve 71, and the end face of the end of the sealing body 73 away from the terminal 72 abuts against the end cover 74.

[0044] In the optional embodiment, one end of the end cover 74 is usually provided with a through hole for the wire harness 900 to pass through, and the other end is sleeved outside the sleeve pipe 71 and is in clamping connection with the sleeve pipe 71. In assembly, the wire harness 900 passes through the end cover 74 and the wire sealing body 73 in sequence and is crimped into the terminal 72, and the end face of the wire sealing body 73 away from the terminal 72 abuts against the end cover 74. In this way, the end cover 74 can be used to axially limit the wire sealing body 73, so as to further ensure that the wire sealing body 73 is firmly installed in the sleeve pipe 71; and the clamping connection between the end cover 74 and the sleeve pipe 71 can improve the convenience and efficiency of assembly and facilitate disassembly and assembly.

[0045] Optionally, in combination with Figure 3 and Figure 6 As shown in the figures, the wire inlet interface 2 and the wire outlet interface 3 further comprise a pressing sleeve 75 for crimping the shielding layer of the wire harness 900, the pressing sleeve 75 is embedded in the sleeve pipe 71 and located on the side of the wire sealing body 73 close to the terminal 72, and the pressing sleeve 75 is in abutting connection with the wire sealing body 73.

[0046] Specifically, since the wire harness 900 with a shielding layer is usually a high-voltage wire harness, the pressing sleeve 75 is usually used to crimp the shielding layer of the high-voltage wire harness, wherein the pressing sleeve 75 is usually composed of a wire pressing end 751 and a wire inserting end 752, and the wire pressing end 751 of the pressing sleeve 75 is used to crimp the shielding layer of the high-voltage wire harness. Before crimping, the shielding layer of the high-voltage wire harness usually needs to be stripped and combed in the direction opposite to the insertion direction, and then the shielding layer is crimped by the wire pressing end 751 of the pressing sleeve 75, and the wire core after stripping the shielding layer extends from the wire inserting end 752 of the pressing sleeve 75 and is crimped into the terminal 72.

[0047] In the optional embodiment, by providing the pressing sleeve 75, the shielding layer of the high-voltage wire harness is crimped onto the wire core of the high-voltage wire harness by the pressing sleeve 75, so as to ensure that the wire distribution box can distribute the high-voltage wire harness; and by abutting the pressing sleeve 75 with the wire sealing body 73, the wire sealing body 73 is axially limited by the pressing sleeve 75 and the end cover 74 together, so as to further ensure that the wire sealing body 73 is firmly installed. Moreover, after the shielding layer of the high-voltage wire harness is crimped by the pressing sleeve 75, the wire core of the high-voltage wire harness is isolated from the shielding layer, and at the same time, since the pressing sleeve 75 is embedded in the sleeve pipe 71, the pressing sleeve 75 is in conduction with the metal shell 1 through the sleeve pipe 71 made of metal material, so that the shielding layer of the high-voltage wire harness is in conduction with the shell 1 through the pressing sleeve 75, and thus the entire shell 1 of the wire distribution box can play a role of anti-interference and shielding.

[0048] Optionally, in combination with Figure 3 and Figure 6As shown, the incoming line interface 2 and the outgoing line interface 3 further comprise a limiting piece 76, which is arranged between the sealing line body 73 and the pressing sleeve 75, and the sealing line body 73 and the pressing sleeve 75 respectively abut the end faces of the two ends of the limiting piece 76. The limiting piece 76 is usually a gasket structure. In this way, the limiting piece 76 can be used to axially limit the pressing sleeve 75, so as to ensure that the pressing sleeve 75 can effectively press the shielding layer of the high-voltage wire harness.

[0049] Optionally, in combination with Figure 3 and Figure 6 As shown, the distribution box further comprises a conductive piece 4 arranged in the shell 1, and the terminal 72 of the incoming line interface 2 is connected with the terminals 72 of the plurality of outgoing line interfaces 3 through the conductive piece 4.

[0050] In this way, the terminal 72 of the incoming line interface 2 is connected with the terminals 72 of the plurality of outgoing line interfaces 3 through the conductive piece 4, which can shorten the length of the terminal 72 on the one hand, and on the other hand, for different sizes of the distribution box, the distance between the incoming line interface 2 and the outgoing line interface 3 may not be the same, at this time, the terminal 72 of the incoming line interface 2 can be connected with the terminals 72 of the plurality of outgoing line interfaces 3 by replacing the conductive piece 4 of different sizes, so that the incoming line interface 2 and the outgoing line interface 3 can be adapted to different distribution boxes, thereby improving the versatility of the incoming line interface 2 and the outgoing line interface 3.

[0051] Optionally, in combination with Figure 3 , Figure 4 and Figure 5 As shown, the conductive piece 4 comprises a plurality of conductive sheets 41, and the incoming line interface 2 is provided with a plurality of the conductive sheets 41, the number of the incoming line interfaces 2 and the number of the conductive sheets 41 are the same as the number of columns of the outgoing line interfaces 3, and the terminal 72 of each column of the outgoing line interfaces 3 is connected to the terminal 72 of one of the incoming line interfaces 2 through one of the conductive sheets 41.

[0052] Alternatively, the conductive piece 4 comprises a plurality of conductive sheets 41, and the incoming line interface 2 is provided with a plurality of the conductive sheets 41, the number of the incoming line interfaces 2 and the number of the conductive sheets 41 are the same as the number of rows of the outgoing line interfaces 3, and the terminal 72 of each row of the outgoing line interfaces 3 is connected to the terminal 72 of one of the incoming line interfaces 2 through one of the conductive sheets 41.

[0053] In the optional embodiment, each of the conductive sheets 41 is provided with a first connecting hole 411 and a plurality of second connecting holes 412, and the terminal 72 of the incoming wire interface 2 is connected to the conductive sheet 41 at the first connecting hole 411 by a fastener, and the terminals 72 of the plurality of outgoing wire interfaces 3 in a column or a row are respectively connected to the conductive sheet 41 at the plurality of second connecting holes 412 by fasteners. When the number of the incoming wire interfaces 2 and the number of the conductive sheets 41 are both equal to the number of the rows of the outgoing wire interfaces 3, the main wire connected to one of the incoming wire interfaces 2 is branched from the plurality of outgoing wire interfaces 3 in a row, so that the branch wire harnesses connected to the outgoing wire interfaces 3 are arranged in layers in the column direction, and when the number of the incoming wire interfaces 2 and the number of the conductive sheets 41 are both equal to the number of the columns of the outgoing wire interfaces 3, the main wire connected to one of the incoming wire interfaces 2 is branched from the plurality of outgoing wire interfaces 3 in a column, and the branch wire harnesses connected to the outgoing wire interfaces 3 are arranged in layers in the row direction. Taking the example that the incoming wire interfaces 2 are provided with two and the outgoing wire interfaces 3 are provided with two columns or two rows, at this time, the terminals 72 of the outgoing wire interfaces 3 in one column or one row are connected in conduction to the terminal 72 of one of the incoming wire interfaces by one of the conductive sheets 41, and the terminals 72 of the outgoing wire interfaces 3 in the other column or the other row are connected in conduction to the terminal 72 of the other incoming wire interface by the other conductive sheet 41. In this way, the wire distribution box can branch the plurality of main wire harnesses, so as to further save the laying length of the wire harness 900. In addition, when the incoming wire interfaces 2 are provided with two, the two incoming wire interfaces 2 can be respectively taken as the positive incoming wire interface and the negative incoming wire interface, so that the wire distribution box can branch the positive high-voltage wire harness and the negative high-voltage wire harness.

[0055] In the optional embodiment, the insulator 5 is generally provided with at least one partition plate 51, and the partition plate 51 divides the insulator 5 into a plurality of mounting areas, and the plurality of conductive sheets 41 are respectively arranged in different mounting areas. In this way, when the wire distribution box is used to branch the positive high-voltage wire harness and the negative high-voltage wire harness, the insulator 5 can be used to isolate the positive high-voltage wire harness and the negative high-voltage wire harness; and the arrangement of the insulator 5 can support the conductive sheets 41, so as to ensure the stable connection between the terminal 72 of the incoming wire interface 2 and the terminals 72 of the plurality of outgoing wire interfaces 3.

[0056] Optionally, as shown in Figure 3 , the wire distribution box further comprises a sealing member 6, and the shell 1 comprises a shell body 11 provided with an opening 113 and a cover plate 12 arranged at the opening 113, and the sealing member 6 is arranged at the opening 113 and sealingly connected to the cover plate 12.
