The input copper bar, the adapter copper bar and the adapter contacts are arranged in the socket shell, the input copper bar is arranged at the input end 6 of the socket shell, and the at least two load wiring harness components are arranged in parallel at the output end 7 of the socket shell, each load wiring harness component is connected in series with at least one adapter contact, and the adapter contact is connected in conduction with the input copper bar through the adapter copper bar, and the input copper bar is arranged in the insertion hole of the input end of the socket shell.

[0042] After the plug and the socket are connected, the input end of the input copper bar is connected in conduction with the output end of the contact, thereby realizing the current distribution from the at least one input wiring harness component to the at least two load wiring harness components.

[0043] In an embodiment, the number of input copper bars and the number of adapter copper bars are equal to the number of contacts in the plug. After the plug and the socket are connected, the current is transmitted from the at least one input wiring harness component to the input copper bar of the socket through the contact, and then is transmitted from the input copper bar to the adapter copper bar, and then is transmitted to the load wiring harness components through the adapter contacts connected with the adapter copper bar, thereby realizing the current distribution.

[0044] On the basis of the above-described embodiment, as shown in Figure 3 The adapter contact comprises an adapter contact I (i.e. the second adapter contact described below) and an adapter contact II (i.e. the third adapter contact described below). The adapter contact I is connected in conduction with the adapter copper bar, the adapter contact II is connected in conduction with the load wiring harness component, and an overload protection element is further connected between the corresponding adapter contact I and the adapter contact II, so as to realize the overload protection of the corresponding load wiring harness component. The overload protection element can be a fuse 8 or other overload protection element.

[0045] The application will be described in detail below with reference to the accompanying drawings:

[0046] In Figures 1-5 In the embodiment shown, the plug includes a plug housing, two input harness components, two contact pieces arranged in the plug housing, the input harness components are inserted into the plug housing from the input end and connected to the input end of the corresponding contact pieces, and the output end of the contact pieces is arranged in the socket of the output end of the plug housing.

[0047] The socket includes a socket housing, two input copper bars, two adapter copper bars, nine adapter pieces, and six load harness components as outputs. The two input copper bars are defined as a first input copper bar 9 and a second input copper bar 10, the two adapter copper bars are defined as a first adapter copper bar 11 and a second adapter copper bar 12, and the nine adapter pieces are divided into three groups of three each, namely a first adapter piece 13, a second adapter piece 14, and a third adapter piece 15. Three first load harness components 16 are arranged in parallel and connected in series with the three first adapter pieces 13, respectively. The three first adapter pieces are arranged in parallel and connected in series with the first adapter copper bar 11, and the first adapter copper bar 11 is connected in series with the first input copper bar 9.

The three third adapter pieces 15 and the three second adapter pieces 14 are one-to-one corresponding, and every two corresponding third adapter pieces and second adapter pieces form a group, and an overload protection element is connected between them. In the embodiment shown in the figure, the overload protection element is an insurance 8. The three second adapter pieces are connected in series with the second adapter copper bar, and the second adapter copper bar is connected in series with the second input copper bar.

[0048] With the above scheme, the two input harness components in the plug are connected and conducted with the two contact pieces, respectively. After the plug and the socket are plugged in, the two contact pieces are connected and conducted with the two input copper bars in the socket, the current is transmitted to the first input copper bar, then to the first adapter copper bar, then to the three first adapter pieces, and finally to the three first load harness components 16 for output. Another current is transmitted to the second input copper bar, then to the second adapter copper bar, then to the three second adapter pieces, and finally to the three second load harness components 17 for output. Thus, the current can be divided into three and six.

[0049] However, the application is not limited to the structure and number of the above-mentioned embodiments. In other embodiments, the number of input harness components and load harness components can be designed according to specific application scenarios, and the number of corresponding contact pieces, input copper bars, adapter copper bars, and adapter pieces can be selected.

[0050] Further, in Figure 5In the illustrated embodiment, the contact input end is a semi-enclosed socket with a certain degree of elastic deformation. The wires of the input wiring harness are inserted into this socket and pressurized against the contact to achieve fixation and conductive connection. The contact output end is a socket adapted to the input copper busbar socket. After the headstock is inserted, the input copper busbar is inserted into the socket of the contact output end to achieve current conduction.

[0051] In other embodiments, the contact can also be connected and fixed to the wires of the input wiring harness component by means of screw fixing or crimping. Furthermore, the mating end of the input copper busbar can also be made into a socket structure. In this case, the output end of the contact is set as a insert or pin structure. When the head is inserted, the output end of the contact and the mating end of the input copper busbar are inserted to achieve connection and conduction.

[0052] In other embodiments, the contact can be made as a single piece or as a separate piece. In the separate structure, the contact input end (i.e., the end where the contact connects to the input wiring harness component) and the contact output end are each independent parts, which are assembled together to achieve electrical connection. Therefore, in this invention, the specific structure of the contact is not limited; its main purpose is to achieve the connection and conduction between the input wiring harness component and the input copper busbar after the head and base are plugged in.

[0053] Furthermore, the input copper busbar and the adapter copper busbar, the adapter copper busbar and the adapter component, and the adapter component and the load harness component can be connected by screws. In other embodiments, a crimping method can also be used for fixing.

The other two first adapter components II 13.2 are directly connected to the first adapter copper busbar 11. The first adapter component I 13.1 is fixed to the first input copper busbar 9 and the first adapter copper busbar 11 with screws, and the first adapter component II 13.2 is fixed to the first adapter copper busbar 11 with screws, which can realize the transmission of current from the first input copper busbar 9 to the first adapter component I 13.1 and the two first adapter components II 13.2.

[0055] Furthermore, the plug housing and socket housing can be fixed with screw I18 after being plugged in, which facilitates disassembly and improves shock resistance.

[0056] Further, for the convenience of disassembly and maintenance, the socket shell can be provided in a detachable structure. The socket shell at least comprises an upper cover 19 and an outer shell 20, and the upper cover and the outer shell are fixed by screws. The second input copper bar, the second adapter copper bar, the second adapter, the overload protection element and the third adapter are all arranged above the first input copper bar, the first adapter copper bar and the first adapter, i.e. the second input copper bar, the second adapter copper bar, the second adapter, the overload protection element and the third adapter are arranged in the upper half of the socket shell, and when the overload protection element needs to be maintained or replaced, the upper cover can be opened to replace the overload protection element. At the same time, the bottom of the outer shell is provided with a convex edge 21, and the convex edge is provided with a screw hole, and the socket can be fixed to the vehicle body by the screw II 22.

[0057] Further, in an embodiment, the vehicle body power supply is connected with a device end connector, part of the output end of the device end connector is connected with the input wire harness component of the plug of the wiring connector of the application, i.e. the load end of the device end connector is connected with the input end of the plug of the application. The negative pole of the output of the device end connector is connected with one input wire harness component of the plug of the application, and the positive pole of the output of the device end connector is connected with another input wire harness component of the plug of the application. In an embodiment, after the head seat is inserted, the negative pole current is transmitted to the first input copper bar, and finally transmitted to the three first load wire harness components 16 through the first adapter copper bar and the first adapter. The positive pole current is transmitted to the second input copper bar, and is shunted to the three second load wire harness components 17 through the second adapter copper bar, the second adapter and the third adapter, and the fuse is installed between the second adapter and the third adapter, so that the shunt of the positive pole circuit and the overload protection of the positive pole circuit can be realized.

[0058] In other embodiments, the fuse can also be installed on the negative pole circuit.

[0059] In other embodiments, a temperature sensor can also be connected in series between the input copper bar and the load wire harness component, so that the temperature of the part of the load circuit can be detected in real time. Other functional modules can also be connected in series between the input copper bar and the load wire harness component according to the needs, so that the functional application of the wiring connector can be realized.

[0060] In an embodiment, the input wire harness component inputs a small current, but the application is not limited thereto.

[0061] In an embodiment, the input wire harness component and the load wire harness component are high-voltage input wire harness components and high-voltage load wire harness components, but the application is not limited thereto.

[0062] The application can integrate the distribution function and overload protection function of the vehicle-mounted power distribution equipment in one distributor, and the distributor is integrated with the socket connector, so that the number of used connectors is reduced, the cost is lowered, and the installation space is saved. The socket connector is installed in the vehicle body by screws, so that the installation mode is more free and the installation position is more flexible. The current input wire harness and the load wire harness are connected by the head seat insertion mode, so that the vehicle body wiring and assembly are more convenient.

[0063] The above is only the embodiment of the application, and does not limit the application in any form.
