Description

RELATED APPLICATIONS The present application claims priority to Chinese Patent Application No. 202110876044.0 filed on July 30, 2021, and also claims priority to Chinese Utility Model Patent Application No. 202121766135.0 filed on July 30, 2021. TECHNICAL FIELD The present disclosure relates to the technical field of electrical connection, in particular to a wiring harness module and a combined wiring harness. BACKGROUND As the electrical functions of transportation such as automobiles, trains and ships become more and more complex, there are more and more corresponding electrical circuits. Correspondingly, there are more and more wiring harness circuits configured to connect the various electrical devices and the power supply. As a result, the wiring harness gradually becomes large and complex. For example, the main wiring harness of the body of a C-class car has about 800-1000 circuits, which are assembled into a large wiring harness and distributed in various positions of the car body. When the wiring harness is partially damaged, the entire wiring harness has to be replaced. In addition, due to reasons such as personalized customization, the circuits and branches of the wiring harness are tended to be made flexible gradually, different types of wiring harnesses need to be produced at the same time, and the methods for large batch production are no longer suitable. Accordingly, a lot of special equipment and technical equipment are added, which requires high requirements for the skills of the production personnel and the wiring harness detection ability. Therefore, it is extremely difficult to produce and maintain complex wiring harnesses. A vehicular circuit body routed in a vehicle is known from the prior art, for example from US2019/126860A1. An electricity conductor unit is known from the prior art, for example from US2218545A. A surface mounted component using strip line conductors for surface wiring is known from the prior art, for example from US7205477B1. A wiring member, a manufacturing method of a wiring member, and a wiring member connection structure are known from the prior art, for example from US2018/174716A1. A harness comprising wiring harness modules according to the preamble of claim 1 is known from the prior art, for example from JP2007305379A. An automobile wire harness lead plug is known from the prior art, for example from CN213400671U. SUMMARY The present invention is defined by the independent claim 1.
