The first junction box 1 and the second junction box 2 can be partially or completely superimposed in structure, as long as the first wiring harness assembly 145 and the second wiring harness assembly 25 in the wiring harness adapter connector can be located in different planes in the superimposed space and can be electrically connected.

[0095] In one embodiment, if Figure 4 , Figure 6 As shown, the wiring harness adapter connector also includes:
[0096] The first screw 11 passes through the cover plate 12, the first junction box 1 and the second metal shell 22 in sequence to achieve fixed connection between the first junction box 1 and the second junction box 2. The first screw 11 is relatively long to ensure that it can enter the second junction box 2.
[0097] In one embodiment, if Figure 4 , Figure 6 As shown, the wiring harness adapter connector also includes:
[0098] The second screw 13 is arranged along the axis direction of the wiring harness adapter connector with the first screw 11, and the second screw 13 is used to connect the first plastic shell 141 and the second metal shell 22 to achieve a fixed connection between the first junction box 1 and the second junction box 2. By providing the second screw 13 and the first screw 11, the first junction box 1 and the second junction box 2 can be stably fixedly connected, and the first junction box 1 and the second junction box 2 can be prevented from being misaligned after being fixedly connected.
[0099] The length of the second screw 13 is smaller than that of the first screw 11 because the first junction box 1 and the second junction box 2 are both designed as triangular blocks or trapezoidal blocks with different thicknesses. The thickness is larger at the location where the first screw 11 is connected, and the thickness is smaller at the location where the second screw 13 is connected.

When the first screw 11 passes through the first junction box 1 and is inserted into the plastic sleeve 144, the interference fixes the first screw 11 and the first junction box 1 assembly so that they do not fall off, thereby achieving the purpose of pre-installation.

At the same time, the sheet metal part 3 and the first metal shell 142 or the second metal shell 22 can also be constructed into an electromagnetic shielding circuit, which can improve the safety of the wiring harness connection.
[0112] In one embodiment, if Figure 3 , Figure 4 As shown, the first junction box 1 also includes:
[0113] The terminal sheath 143 is disposed in the first accommodation cavity and is used to fix the terminal of the first harness assembly 145 to prevent the terminal of the first harness assembly 145 from withdrawing from the first accommodation cavity. The terminal sheath 143 is buckled onto the terminal of the first harness assembly 145 so that the terminal is positioned and prevented from withdrawing when inserted into the first junction box 1, which facilitates the subsequent first terminal screw 146 to lock the terminal of the first harness assembly 145.

[0115] The terminal 21 is arranged in the first terminal box 1 and the second terminal box 2, the first end of the terminal 21 is used to connect the terminal of the first wiring harness assembly 145, and the second end is used to connect the terminal of the second wiring harness assembly 25, so that the first wiring harness assembly 145 and the second wiring harness assembly 25 are electrically connected.
[0116] The number of the terminals 21 is set according to the number of the first wiring harness assembly 145 and the second wiring harness assembly 25. The figure shows that the first wiring harness assembly 145 and the second wiring harness assembly 25 are both two wires arranged side by side, and there are two corresponding terminals 21, which are also arranged side by side.

[0127] The first wire harness assembly 145 and the second wire harness assembly 25 in this embodiment may be formed by twisting a plurality of monofilament conductors, or may be formed by a single solid conductor.

The connectors at both ends can use two different cables respectively, providing flexible usage scenarios and conditions for the use and promotion of the solid busbar 26.
[0129] The high-power shielded circular solid busbar for charging and distribution of electric vehicles and the matching high-voltage shielded circular solid busbar are both circular solid structures with many advantages such as low cost, compact structure, strong conductivity, excellent heat dissipation performance, physical flame retardancy, etc. They provide the possibility for high-power charging and distribution within the limited layout space inside the vehicle and have broad application prospects in the future.
[0130] An embodiment of the utility model further provides an electrical device, comprising a wiring harness adapter connector according to any one of the above embodiments.
[0131] The electrical equipment may be a vehicle, a ship, a spacecraft, etc. The vehicle may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. The spacecraft includes an airplane, a rocket, a space shuttle and a spacecraft, etc. The present application embodiment does not impose any special restrictions on the above-mentioned electrical equipment.
[0132] In one embodiment, if Figure 1 , Figure 2 As shown, the electrical equipment also includes:
[0133] The sheet metal part 3, the first junction box 1 or the second junction box 2 are connected to the sheet metal part 3 to fix the wiring harness adapter connector, the first junction box 1 and the second junction box 2 can be distributed on both sides of the sheet metal part 3, and the sheet metal part 3 is provided with a through hole for accommodating the first junction box 1 or the second junction box 2. The sheet metal part 3 can be a sheet metal of a car body, a sheet metal of a hull, a sheet metal of a spacecraft, etc.
[0134] The utility model provides a wiring harness adapter connector and an electrical device, which have the following characteristics:
[0135] 1. The connector can meet the 960H salt spray resistance requirement, using the plastic coating process to evenly coat the plastic on the outside of the metal parts. This connector structure relies on the characteristics of the plastic parts themselves that can withstand high salt spray levels, and does not require additional surface treatment, which greatly saves the cost of the connector; in addition, this connector can ensure structural strength while the metal parts wrapped inside act as a shielding layer, greatly simplifying the subsequent assembly process.
[0136] 2. The first junction box and the second junction box of the connector are fixed by a center screw and a top screw: one screw is locked at the top of the connector, and the other screw passes through the center of the upper cover and is fixed to the threaded hole of the metal plastic-coated part of the second junction box. While fixing the upper cover (cover plate 12), the locking force required for the first junction box and the second junction box to be matched and fixed is provided, abandoning the traditional connection method of fixing the four corners of the upper cover with screws and fixing the connector and the body sheet metal with screws.
[0137] Through the above-mentioned screw connection method: the body sheet metal only needs two screws to fix the second junction box, and the first junction box is fixed to the threaded hole of the second junction box by screws, which reduces the use of screws, thereby reducing material costs, simplifying assembly, and reducing the risk of missing screws in the connector; in addition, the design of center-fixed screws reduces the outer contour of the connector to reduce the space reserved for screw installation, and the size and weight of the connector are reduced; furthermore, the metal cover acts as a shielding structure of the connector. When shielding a traditional connector, the cover needs to be added with a spring sheet and a reserved contact structure to achieve a stable connection. This connector does not require a spring sheet and a reserved contact contact. While fixing the cover, the screw conducts the shielding current of the cover to the metal shell of the second junction box, and the connection is stable and reliable.
[0138] 3. A pre-installed rubber sleeve is installed inside the threaded hole of the first junction box. The petal-shaped shape of the rubber sleeve makes the rubber sleeve have elastic properties that can be compressed and expanded. The protruding position of the rubber sleeve interferes with the threaded hole and can be firmly fixed by pressing it into the threaded hole. When the screw passes through, the recessed structure interferes with the thread, so that the screw and the upper cover assembly are pre-installed on the first junction box. The design of this pre-installed structure enables the first junction box to rely on the pre-installed screws to fix the upper cover and the connector when it is not assembled with the second junction box, avoiding the risk of missing the internal components of the connector during transportation, and also making the connector waterproof and dustproof, protecting the internal components from contamination; the pre-installed structure also reduces the difficulty of final assembly and improves the efficiency of final assembly.
