For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figure 1 As shown, the utility model relates to a wiring harness assembly, including a junction box assembly and wires 300, wherein the wires 300 are connected to the junction box assembly.

[0036] like Figure 2 As shown, the junction box assembly includes a junction box 100 , a gasket 130 and a mounting plate 200 .

[0037] Combination Figure 2 and Figure 3The junction box 100 includes a junction box body 110 and a buckle 120. The junction box body 110 is used to connect the wire 300; the buckle 120 is connected to the junction box body 110, and the buckle 120 is used to be clamped on the mounting plate 200, so as to fix the junction box 100.

[0038] like Figure 4 As shown, the buckle 120 includes a connecting portion 121 and at least two elastic clamping portions 122, the first end of the connecting portion 121 is connected to the junction box body 110, the first ends of at least two elastic clamping portions 122 are connected to the second end of the connecting portion 121, the second ends of at least two elastic clamping portions 122 are spaced apart from the junction box body 110, and at least two elastic clamping portions 122 are arranged at an acute angle to the connecting portion 121.

[0039] Specifically, the connecting portion 121 includes two opposite ends, the first end of the connecting portion 121 is connected to the bottom of the junction box body 110, and the connecting portion 121 extends from the bottom of the junction box body 110 away from the junction box body 110; the elastic clamping portion 122 includes two opposite ends, the first end of the elastic clamping portion 122 is connected to the second end of the connecting portion 121, and the elastic clamping portion 122 extends from the second end of the connecting portion 121 toward the bottom of the junction box body 110, and the elastic clamping portion 122 is arranged at an acute angle to the connecting portion 121, and the second end of the elastic clamping portion 122 is spaced from the bottom of the junction box body 110.

[0040] In addition, at least two elastic clamping parts 122 are arranged at intervals along the circumference of the connecting part 121. Specifically in this embodiment, the number of the elastic clamping parts 122 is two, and the two elastic clamping parts 122 are respectively arranged on both sides of the connecting part 121, that is, the two elastic clamping parts 122 are arranged opposite to each other. Of course, in other embodiments, the number of the elastic clamping parts 122 can also be three or more, and the three or more elastic clamping parts 122 are arranged at intervals along the circumference of the connecting part 121.

[0041] It should be noted that the elastic clamping portion 122 and the connecting portion 121 are an integral structure and are made of plastic. The elastic clamping portion 122 can deflect toward the connecting portion 121 after being compressed, and can return to its original position when the external force disappears.

[0042] like Figure 4 As shown, the gasket 130 is sleeved outside the connecting portion 121 and is located on the side of the second end of the elastic clamping portion 122 close to the junction box body 110; wherein the buckle 120 is passed through the clamping hole 210 of the mounting plate 200 so that the mounting plate 200 is clamped between the gasket 130 and the second end of the elastic clamping portion 122.

[0043] When installing the junction box assembly of the utility model, the wire 300 can be connected to the junction box 100 first, and then the gasket 130 is arranged outside the connecting portion 121 of the buckle 120, and then the buckle 120 is inserted into the clamping hole 210 of the mounting plate 200, so that the mounting plate 200 is clamped between the gasket 130 and the second end of the elastic clamping portion 122, and the junction box 100 is fixed. In this way, the installation operation of the junction box 100 is simple, which is more convenient than bundling with a cable tie.

[0044] In addition, there are many types of gaskets 130, and different types of gaskets 130 have different thicknesses, and various gaskets 130 can be selectively sleeved outside the connecting portion 121. In this way, gaskets 130 of different thicknesses can be matched according to mounting plates 200 of different thicknesses, thereby improving versatility.

[0045] It should be noted that the gasket 130 is an annular gasket, and the buckle 120 can pass through the gasket 130 so that the gasket 130 is sleeved outside the connecting portion 121 .

[0046] like Figure 5 As shown, in some embodiments, the junction box body 110 includes a box body 111, a cover body 112 and a wire limiter 113, one end of the box body 111 is provided with at least one first wire passing hole 111a, and the other end of the box body 111 is provided with at least one second wire passing hole 111b, the wire limiter 113 is movably arranged inside the box body 111, and the cover body 112 is covered on the box body 111; wherein, the wire limiter 113 includes at least one first limiter 1131 for limiting the wire 300 extending into the box body 111 through the first wire passing hole 111a, and at least one second limiter 1132 for limiting the wire 300 extending into the box body 111 through the second wire passing hole 111b.

[0047] Specifically, the wire 300 includes a first wire 310 and a second wire 320; the box body 111 includes two opposite ends, one end of which is provided with a first wire hole 111a for the first wire 310 to pass through, and the other end is provided with a second wire hole 111b for the second wire 320 to pass through. When the first wire 310 passes through the first wire hole 111a and enters the box body 111, it can cooperate with the first limiting portion 1131 and be limited by the first limiting portion 1131; when the second wire 320 passes through the second wire hole 111b and enters the box body 111, it can cooperate with the second limiting portion 1132 and be limited by the second limiting portion 1132. Thus, when the first wire 310 is pulled, the wire stopper 113 can be moved, thereby driving the second wire 320 to move. Conversely, when the second wire 320 is pulled, the wire stopper 113 can be moved, thereby driving the first wire 310 to move.

[0048] Specifically in this embodiment, the number of the first wire passing hole 111 a is one, the number of the second wire passing holes 111 b is two, the number of the first wire 310 is one, and the number of the second wire 320 is two.

[0049] Combination Figure 5 and Figure 6 Further, the first limiting portion 1131 is a first limiting groove, one end of the first limiting groove passes through one end of the wire limiting member 113 close to the first wire passing hole 111a, and the other end of the first limiting groove passes through one end of the wire limiting member 113 close to the second wire passing hole 111b.

[0050] Specifically, a first terminal 311 is provided at the end of the first wire 310, and the first wire 310 can be passed through the first limiting groove, and the first terminal 311 is against one end of the wire limiting piece 113 close to the second wire hole 111b to achieve the limitation of the first wire 310 and the wire limiting piece 113.

[0051] Furthermore, the second limiting portion 1132 is a second limiting groove, which passes through one end of the wire limiting member 113 close to the first wire passing hole 111a, and the second limiting groove has a blocking portion 1133 at one end close to the second wire passing hole 111b, and the blocking portion 1133 is provided with a through hole 11331 connected to the second limiting groove.

[0052] Specifically, a second terminal 321 is provided at the end of the second wire 320. The second wire 320 can be inserted into the second limiting groove through the through hole 11331, and the second terminal 321 is placed in the second limiting groove, so that the blocking part 1133 limits the second terminal 321, thereby realizing the limitation of the second wire 320 and the wire limiting piece 113.

[0053] It should be noted that the second terminal 321 can be connected to the end of the second wire 320 after the second wire 320 passes through the through hole 11331 and enters the second limiting groove.

[0054] Furthermore, the first wire hole 111a and the second wire hole 111b are both passed through the box body 111 on one side close to the cover 112. In this way, the first wire 310 and the second wire 320 can be inserted into the first wire hole 111a and the second wire hole 111b from top to bottom, respectively, which is more convenient to operate.

[0055] like Figure 4 As shown, in some embodiments, the cover 112 is covered on the box body 111, and the cover 112 is snap-fitted with the box body 111. In this way, the assembly of the cover 112 and the box body 111 can be facilitated.

[0056] Specifically, a card interface 1121 is provided on the cover body 112 , and a snap buckle 1111 is provided on the box body 111 . The snap buckle 1111 is snapped into the card interface 1121 to achieve snap connection between the cover body 112 and the box body 111 .

[0057] In the wiring harness assembly of the utility model, when installing the junction box assembly, the wire 300 can be first connected to the junction box 100, and then the gasket 130 can be arranged outside the connecting portion 121 of the buckle 120, and then the buckle 120 can be inserted into the clamping hole 210 of the mounting plate 200 so that the mounting plate 200 is clamped between the gasket 130 and the second end of the elastic clamping portion 122, thereby completing the fixing of the junction box 100. In this way, the installation process of the junction box 100 is simpler and more convenient than bundling with cable ties. In addition, there are many types of gaskets 130, and different types of gaskets 130 have different thicknesses. Multiple gaskets 130 can be selectively sleeved outside the connecting portion 121. In this way, gaskets 130 of different thicknesses can be matched according to mounting plates 200 of different thicknesses, thereby improving versatility.
