A second bolt is threaded onto the second electrical contact piece. A second connecting line is provided at the end of the second lower housing away from the insertion holes.
[0007] Both the first upper housing and the second upper housing have fixing bolts that pass through them, and the fixing bolts on the first upper housing and the second upper housing are respectively threaded to the surfaces of the first lower housing and the second lower housing.
[0008] Preferably, a fixing plate is provided on the outer side of the first connecting line and the outer side of the second connecting line, and a third bolt passes through both sides of the surface of the fixing plate.
[0009] Preferably, a sealing ring is slidably fitted on the outer side of both the first connecting line and the second connecting line, and the sealing ring is elastic.
[0010] Preferably, a right-angled triangular baffle is installed on the surface of the first upper housing, and an elastic hanging plate is installed on the surface of the second upper housing, with the right-angled triangular baffle corresponding to the elastic hanging plate.
[0011] Preferably, a sealing gasket is installed at one end of both the first connector and the second connector, and the sealing gasket is a rubber elastic gasket.
[0012] Preferably, a sealing frame is installed on the surface of both the first lower housing and the second lower housing, and the sealing frame is elastic.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model combines a first upper shell, a first lower shell, a second upper shell, a second lower shell, a first contact piece, a second contact piece, a first bolt, and a second bolt. By tightening the first bolt, the first upper shell or the second upper shell can be disassembled. Then, according to the damaged connecting wire, the corresponding second bolt is tightened to separate the connecting wire from the first and second contact pieces. Then, by tightening the second bolt, the replacement connecting wire is connected to the first or second contact piece, thereby completing the replacement of the damaged connecting wire on the wire harness. Thus, when one connecting wire of the wire harness is damaged during use, it is convenient to disassemble and replace the damaged connecting wire, so as not to replace the entire wire harness, thereby reducing the replacement cost of the connecting wire harness.
[0015] 2. By combining the fixing plate and the third bolt, when the connecting wire is connected to the first connector and the second connector, the third bolt is tightened in conjunction with the fixing plate to fix the connecting wire to the first lower housing and the second lower housing, thereby avoiding the wire harness from detaching from the first connector or the second connector due to traction during wire harness connection, which would affect the stability of the wire harness connection.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0021] Example 1: A wiring harness for new energy vehicles, see [link / reference] Figures 1 to 3 The system includes a first connector 1 and a second connector 2. The first connector 1 includes a first lower housing 12 and a first upper housing 11. Connectors 15 are installed on both sides of one end of the first lower housing 12. Each connector 15 has a connecting hole 16. A first contact piece 17 is connected to one end of each connector 15, and a first bolt 18 is threaded onto the first contact piece 17. First connecting lines 13 are provided on both sides of the end of the first lower housing 12 away from the connectors 15. The second connector 2 includes a second lower housing 22 and a second upper housing 21. Insertion holes 25 are provided on both sides of one end of the second lower housing 22. Connecting posts 26 are installed inside the cavities of both insertion holes 25. Second contact pieces 27 are connected to the connecting posts 26, and second bolts 28 are threaded onto the second contact pieces 27. A second connecting line 23 is provided on the end of the second lower housing 22 away from the insertion holes 25. Fixing bolts 4 penetrate both the first upper housing 11 and the second upper housing 21. The fixing bolts 4 on the second upper housing 21 are threadedly connected to the surfaces of the first lower housing 12 and the second lower housing 22 respectively. During operation, the connector 15 is inserted into the insertion hole 25, and the connecting post 26 is inserted into the connecting hole 16, thereby connecting the first connector 1 and the second connector 2 to complete the connection of the wire harness. When one of the connecting wires is damaged during the use of the wire harness, the first upper housing 11 or the second upper housing 21 is disassembled by turning the first bolt 18. Then, according to the damaged connecting wire, the corresponding second bolt 28 is turned to separate the connecting wire from the first contact piece 17 and the second contact piece 27. Then, the replacement connecting wire is connected to the first contact piece 17 or the second contact piece 27 by turning the second bolt 28, thereby completing the replacement of the damaged connecting wire on the wire harness. Thus, when one of the connecting wires is damaged during the use of the wire harness, it is convenient to disassemble and replace the damaged connecting wire, so as not to replace the entire wire harness, thereby reducing the replacement cost of the connecting wire harness.
[0022] For details, see Figure 2 and Figure 3 A fixing plate 6 is provided on the outer side of the first connecting line 13 and the outer side of the second connecting line 23. A third bolt 61 is passed through both sides of the surface of the fixing plate 6. With the fixing plate 6 and the third bolt 61, when the connecting line is connected to the first connector 1 and the second connector 2, the third bolt 61 is tightened to fix the connecting line to the first lower housing 12 and the second lower housing 22 in conjunction with the fixing plate 6, thereby avoiding the pulling of the wire harness during the connection and causing the wire harness to detach from the first connector 1 or the second connector 2, which affects the stability of the wire harness connection.
[0023] Further, see Figure 1 — Figure 3 A sealing ring 3 is slidably fitted on the outer side of the first connecting line 13 and the second connecting line 23, and the sealing ring 3 is elastic. A sealing gasket 5 is installed on the opposite end of the first connector 1 and the second connector 2, and the sealing gasket 5 is a rubber elastic gasket. A sealing frame 7 is installed on the surface of the first lower housing 12 and the second lower housing 22, and the sealing frame 7 is elastic. The sealing ring 3 increases the sealing effect of the connection between the first connecting line 13 and the second connecting line 23 and the first connector 1 and the second connector 2, respectively. The sealing gasket 5 increases the sealing effect of the connection between the first connector 1 and the second connector 2. The sealing frame 7 increases the sealing effect of the connection between the first upper housing 11 and the first lower housing 12 and the second upper housing 21 and the second lower housing 22, further improving the overall sealing effect of the wire harness connection.
[0024] It is worth noting that, see Figure 1 A right-angled triangular baffle 14 is installed on the surface of the first upper housing 11, and an elastic hanging plate 24 is installed on the surface of the second upper housing 21. The right-angled triangular baffle 14 corresponds to the elastic hanging plate 24. The elastic hanging plate 24 passes over and hangs on the right-angled triangular baffle 14, thereby improving the stability of the connection between the first connector 1 and the second connector 2.
