[0035] In order to make the technical problems, technical schemes and beneficial effects solved by the utility model more clearly understood, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.

[0036] As shown in Figure 1 and Figure 2 In an embodiment, the conductive bar 1 is provided with a first limiting structure 11, and the first limiting structure 11 is adapted to abut against a second limiting structure 21 on the wire lug 2 to block the rotation of the wire lug 2 relative to the conductive bar 1. In this way, the wire lug 2 can be effectively prevented from rotating relative to the conductive bar 1 under the action of the wire harness 3 connected thereto, thereby preventing the connection between the wire lug 2 and the conductive bar 1 from loosening.

[0037] The conductive bar 1 can be applied to a power distribution device 10, and in this case, the conductive bar 1 can be electrically connected to the corresponding terminal. In addition, the material of the conductive bar 1 can be copper, aluminum, etc.

[0038] As shown in Figure 1 In an embodiment, the conductive bar 1 is provided with a first connecting hole 12, and the first connecting hole 12 penetrates the conductive bar 1. The first connecting hole 12 is adapted to cooperate with a connecting piece to connect the wire lug 2 to the conductive bar 1 through the connecting piece. The connecting piece can include a bolt and a nut. During assembly, the bolt passes through the first connecting hole 12, penetrates the wire lug 2 from the perforated portion on the wire lug 2, and cooperates with the nut to lock the conductive bar 1 and the wire lug 2 together.

[0039] In some embodiments, the first connecting hole 12 may also be a threaded hole, in which case the connector may be a bolt (excluding the nut). The bolt passes through the through hole on the lug 2 and engages with the threaded connection hole 12, thereby locking the conductive busbar 1 and the lug 2 together.

[0040] like Figure 1 As shown, in one embodiment, the conductive bus 1 includes a first surface 13 and a second surface 14 disposed opposite to each other, wherein the first surface 13 and the second surface 14 are two surfaces in the thickness direction of the conductive bus 1, and the first connecting hole 12 penetrates through the first surface 13 and the second surface 14. At least one of the first surface 13 and the second surface 14 is adapted to connect a lug 2, that is, the lug 2 can be placed on the first surface 13, and after assembly, the lug 2 is pressed on the first surface 13; or, the lug 2 can also be placed on the second surface 14, and after assembly, the lug 2 is pressed on the second surface 14; or, one lug 2 can be placed on each of the first surface 13 and the second surface 14, and after assembly, the two lugs 2 and the conductive bus 1 are locked together, and one lug 2 is pressed on the first surface 13 and the other lug 2 is pressed on the second surface 14.

[0041] like Figure 1 As shown, in one embodiment, the conductive bus 1 further includes a side surface 15. In the thickness direction of the conductive bus 1, the side surface 15 is located between the first surface 13 and the second surface 14, and the side surface intersects the first surface 13 and the second surface 14 respectively. The first limiting structure 11 is disposed on the side surface 15, which makes it easier to prepare the first limiting structure 11.

[0042] like Figure 1 As shown, in one embodiment, the first limiting structure 11 can be a limiting groove, a limiting hole, or a stop. When the first limiting structure 11 is a limiting groove or a limiting hole, the second abutting structure is a limiting hole; when the first limiting structure 11 is a stop, the second abutting structure is a limiting hole, a limiting groove, or a stop.

[0043] When the first limiting structure 11 is a limiting groove, the limiting groove can penetrate through the first surface 13 and the second surface 14. After assembly, the second limiting structure 21 is located inside the limiting groove and abuts against the side wall of the limiting groove, thereby preventing the wire lug 2 from rotating. This arrangement makes it easier for the first limiting structure 11 and the second limiting structure 21 to cooperate.

[0044] When the first limiting structure 11 is a limiting hole, the limiting hole can penetrate through the first surface 13 and the second surface 14. After assembly, the second limiting structure 21 is located inside the limiting hole and abuts against the side wall of the limiting hole, thereby preventing the lug 2 from rotating. This arrangement makes it easier for the first limiting structure 11 and the second limiting structure 21 to cooperate.

[0045] When the first limiting structure 11 is a block, and the first limiting structure 11 is arranged on the side surface 15, in the arrangement direction of the first surface 13 and the second surface 14, one end of the block is flush with the first surface 13, and the other end of the block is flush with the second surface 14, so that the production of the first limiting structure 11 is more convenient.

[0046] In an embodiment, the conductive strip 1 has a plurality of connecting regions, the connecting regions are suitable for connecting the wire lug 2; each connecting region is provided with the first limiting structure 11. Wherein, "a plurality of" means greater than or equal to two, and the meaning of the word "a plurality of" in each embodiment is the same, and will not be repeated hereinafter.

[0047] Wherein, the connecting region is the region supporting the wire lug 2, when the connecting region is provided with a plurality of connecting regions, the first connecting hole 12 is also provided with a plurality of first connecting holes 12, and each connecting region is provided with the first connecting hole 12. Usually, one connecting region is provided with one first connecting hole 12, of course, one connecting region can also be provided with a plurality of first connecting holes 12.

[0048] When assembling, one connecting region is installed with one wire lug 2, and in the installation region, only one first limiting structure 11 can be arranged, or a plurality of first limiting structures 11 can be arranged.

[0049] In an embodiment, when the number of the first limiting structure 11 is a plurality, the structure of each first limiting structure 11 can be the same, or at least two first limiting structures 11 can be different. For example, in the example shown in the figure, the number of the first limiting structure 11 is three, wherein two first limiting structures 11 are blocks, and the other limiting structure is a limiting groove. In addition, in this embodiment, the conductive strip 1 has three connecting regions, each connecting region is provided with one first connecting hole 12, and each installation region is provided with one limiting structure. Figure 1

[0050] In the prior art, the conductive strip 1 is usually a straight plate structure, and the two ends thereof can be respectively used for electrically connecting corresponding target objects, and the target objects can be terminals of a power distribution device, etc. When it is necessary to realize the electrical connection among three target objects, it is necessary to arrange two conductive strips 1, wherein one end of the first conductive strip 1 is electrically connected with the first target object and the second target object respectively, so as to realize the electrical connection between the two target objects; one end of the second conductive strip 1 is electrically connected with the third target object, and the other end of the second conductive strip 1 is locked on the first conductive strip 1 through a bolt or the like, so as to realize the electrical connection between the two conductive strips 1, so that the three target objects are finally electrically connected together. In this way, the number of the conductive strips 1 is too large, and it is necessary to lock the two conductive strips 1 together through a bolt or the like fastener, which is complicated to operate and needs to occupy a large space.

[0051] For this purpose, as shown in the figure, the conductive strip 1 has a plurality of connecting regions, and each connecting region is provided with the first limiting structure 11. Figure 3 ​As shown, in an embodiment, the conductive row 1 comprises a first conductive section 16 and a second conductive section 17; one end of the second conductive section 17 is electrically connected to a middle part of the first conductive section 16; the other end of the second conductive section 17 is arranged apart from the first conductive section 16; the first conductive section 16 and the second conductive section 17 are of an integral structure.

[0052] In use, the first conductive section 16 and the second conductive section 17 can be electrically connected to corresponding target objects. When the conductive row 1 is electrically connected to three target objects, the two ends of the first conductive section 16 are electrically connected to the first target object and the second target object respectively, and the second conductive section 17 is electrically connected to the third target object.

[0053] In this way, at least three target objects can be electrically connected by using only one conductive row 1, without using two (or other number) of conductive rows 1 as in the prior art. Compared with the prior art, the embodiment eliminates the need for fasteners and other settings for connecting two conductive rows 1, which facilitates assembly and reduces the occupation of space.

[0054] In addition, the "one end of the second conductive section 17 is electrically connected to a middle part of the first conductive section 16" can mean that the two ends of the first conductive section 16 are both arranged apart from the second conductive section 17. In this case, the conductive row 1 is equivalent to having three connecting arms, wherein the part between the one end of the first conductive section 16 and the region where the first conductive section 16 is connected to the second conductive section 17 is one connecting arm, the part between the other end of the first conductive section 16 and the region where the first conductive section 16 is connected to the second conductive section 17 is one connecting arm, and the second conductive section 17 is one connecting arm.

[0055] In addition, the first conductive section 16 and the second conductive section 17 can each be provided with the first limiting structure 11.

[0056] In an embodiment, the conductive row 1 has a bending part. Along the extension direction of the conductive row 1, the conductive row 1 comprises a first section structure 18, a second section structure 19 and a third section structure 1a connected in sequence. In the thickness direction of the conductive row 1, the first section structure 18, the second section structure 19 and the third section structure 1a are arranged in sequence, so that the first section structure 18, the second section structure 19 and the third section structure 1a are connected to form a bending part. This arrangement can avoid the structure of the partition plate in the power distribution device, and at the same time, it can also reduce the length of the conductive row 1.

[0057] When the conductive row 1 comprises the first conductive section 16 and the second conductive section 17, either of the first conductive section 16 and the second conductive section 17 can be provided with the above-mentioned bending part.

[0058] As shown in the drawings, Figures 4 to 6As shown, the utility power distribution device 10 includes at least one wire lug 2 and at least one conductive strip 1 according to any one of the above embodiments. The wire lug 2 is electrically connected to the conductive strip 1. The wire lug 2 has a second limiting structure 21, and the first limiting structure 11 and the second limiting structure 21 are in contact to prevent the wire lug 2 from rotating relative to the conductive strip 1.

[0059] As shown, in an embodiment, the utility power distribution device 10 further includes a first target object, a second target object, and a third target object. In this case, the at least one conductive strip 1 includes a first conductive strip 1b, which is the conductive strip 1 including the first conductive section 16 and the second conductive section 17. The two ends of the first conductive section 16 are electrically connected to the first target object and the second target object, respectively. The second conductive section 17 is electrically connected to the third target object. Figures 4 to 6

[0085] In one embodiment, the structure of the first output terminal 5a is the same as that of the second output terminal 5b.

[0086] like Figure 9 As shown, in one embodiment, the second output terminal 5b includes a second substrate 51, a support member 52, a third terminal post, a fourth terminal post, a third sleeve 53, a fourth sleeve 54, and a second baffle 55; wherein, the second substrate 51 has a third plate surface 511 and a fourth plate surface 512 disposed opposite to each other, the second substrate 51 is provided with a third mounting hole, the third mounting hole penetrates the third plate surface 511 and the fourth plate surface 512, the support member 52 is installed in the third mounting hole, the third terminal post and the fourth terminal post are installed on the support member 52 and both protrude from the third plate surface 511 and the fourth plate surface 512, the third sleeve 53 and the fourth sleeve 54 are both installed on the side of the support member 52 away from the third plate surface 511, the third terminal post is located in the third sleeve 53, and the fourth terminal post is located in the fourth sleeve 54.

[0087] Along the direction from the third plate surface 511 to the fourth plate surface 512, the third pole does not protrude from the third sleeve 53, the fourth pole does not protrude from the fourth sleeve 54, and both the third pole and the fourth pole protrude from the support member 52.

[0088] The second baffle 55 has an annular structure, with one end connected to the third plate surface 511 and surrounding the outside of the third mounting hole. Along the direction from the fourth plate surface 512 to the third plate surface 511, both the third and fourth poles protrude from the support member 52, but neither protrudes from the second baffle 55.

[0089] Additionally, the third electrode post is used to form the first electrode of the second output terminal 5b, and the second electrode post 43 is used to form the second electrode of the second output terminal 5b. Both the third and fourth electrodes can be embedded in the support member 52. In this case, along the arrangement direction of the third plate surface 511 and the fourth plate surface 512, the support member 52 is provided with two mating holes. Both mating holes penetrate the support member 52 and are spaced apart. The third electrode post passes through one mating hole, and the fourth electrode post passes through the other mating hole.

[0090] During assembly, the wire harness 3 can be inserted into the third sleeve 53 to electrically connect to the third terminal, and can be inserted into the fourth sleeve 54 to electrically connect to the fourth terminal.

[0091] Additionally, the second substrate 51 is mounted on the outer surface of the housing 7. For example, the second substrate 51 has a through hole, and the housing 7 has a threaded hole. A corresponding bolt passes through the through hole, passes through the second substrate 51, and engages with the threaded hole on the housing 7, thereby locking the second substrate 51 onto the housing 7. After assembly, the fourth plate surface 512 abuts against the housing 7.

[0092] In addition, the second baffle 55 and the second base plate 51 can be made of insulating material, such as plastic, etc., and can be integrally formed, such as by injection molding. 222

[0093] 223It should be noted that the wire lug 2, the overcurrent protector 6, the wire harness 3, the input terminal 4 and each output terminal can be of existing design, and the present embodiment does not make a detailed description here. 224
