In the embodiment of the present application, the shape and the size of each terminal in the first group of terminals 400 and the second group of terminals 500 are the same, and the shape and the size of the first group of insertion holes 210 and the second group of insertion holes 310 are the same

A conventional harness system will be described with reference to fig. 6 to 9. In the existing wire harness system, a connecting loop is usually connected by one wire or connected by a crimping wire, a plurality of wires are connected among different sheaths, hundreds of wires are interwoven to form a huge and complex network, great difficulty is brought to production, and automatic equipment operation cannot be realized at all. Complex mesh structures cannot be laid out and connected entirely on board, and therefore require packet connections. More loops between the terminal jackets are placed in the same group for connection (interpolation) and the rest are connected on board (extrapolation), almost entirely by manual operation. Because of grouping, there are a large number of external plugs, it is difficult to realize automatic assembly, and production efficiency is extremely low. Even within a group, the variety of terminals limits the application of automation. And the crimping lines exist in a large number, so that the production difficulty is further improved. The automatic and integrated production cannot be realized, the working procedures are too many, and also inevitably causes a great deal of repeated action waste (such as wire-down bundling-Jie Za), transfer and conveying waste (such as conveying of terminal wires) in-transit warehouse, out-transit warehouse, handling, loading into a group rack, etc.), poor quality (e.g., manually grouped misplaced holes, not inserted in place, etc.). The end result is that the entire production process of the existing harness system is still accomplished by a significant amount of labor. Meanwhile, a large number of press lines and welding lines in the wire harness further improve the production difficulty, and increase the raw material cost and the labor cost.

A harness system according to an embodiment of the present application is described with reference to fig. 10-12. In the present embodiment, the terminal sheaths a1, b2 are connected with the second sheath 200A of the connector 10A by the wire harness and the terminals to form group 1; the terminal sheaths c1, i2, i3, j1 are connected with the third sheath 300A of the connector 10A, the second sheath 200B of the connector 10B by the wire harness and the terminals to form group 2; the terminal sheaths d1, d2, d3, d4, k1, e2, e3, e4, m1, m2 are connected with the third sheath 300B of the connector 10B, the second sheath 200B of the connector 10C by wire harnesses and terminals to form a group 3; the terminal jackets f1, g1, h1, n1 are connected with the third jacket 300C of the connector 10C, forming a group 4. Wherein the connection line of the terminal sheath and the connector is a branch line, such as the connection of d1, d2, d3, d4 with the third sheath 300B of the connector 10B; the connector-to-connector connection is a trunk, such as the connection of the third sheath 300A of the connector 10A and the third sheath 300B of the connector 10B. The point location connection sequence in the branch line can adopt wrong sequence connection according to the use requirement, the point location connection sequence in the trunk line adopts sequential connection, and the branch line and the trunk line are combined to realize connection of any point location. The sequential connection and the wrong sequential connection can be produced by adopting automatic terminal inserting equipment. Because the two jackets are connected through the trunk line instead of being directly connected, an interweaved net structure is not formed, and the production process is greatly simplified. After the processing of each group is finished, the connector sheath is abutted, the splicing of each terminal of each loop is not needed, and the production efficiency is greatly improved. The terminals inserted in the connector can use universal terminals, so that the types of the terminals in each group are reduced, and the automatic equipment is convenient for production. The contact pin assembly of the connector can replace the existing press-connection wire and welding wire by arranging the short-circuit contact pin, so that the use of press-connection nails is greatly reduced, the raw material cost and the labor cost caused by press-connection and welding are saved, and obvious benefits can be brought to enterprises.

The existing wire harness system has a plurality of production process procedures, and is basically completed by manpower, and the single-wire procedure comprises: automatic wire feeding, bundling, carrying, warehousing, delivering from warehouse, carrying, assembling, sheath taking, wire taking, terminal inserting, wiring and terminal externally inserting; the crimping process includes: automatic wire feeding, bundling, carrying, warehousing, delivering, carrying, manual crimping, carrying, warehousing, delivering, carrying, assembling, sheath taking, wire taking, terminal inserting, wiring and terminal externally inserting. The harness system of the utility model can sectionalize complicated big pencil, but every section is automated production's structure, and rethread connector combination can realize the automation of most processes in the whole harness system production process, compares the prior art and can practice thrift the manual work by a wide margin, improves production efficiency, and the flow of single line/press wiring only includes: automatic coil inserting, terminal inserting, carrying and sheath butt joint.

Furthermore, in the wire harness system of the embodiment of the application, the connector can be designed in a standardized manner according to the type of the loop, a product sequence is established, the connector is directly selected for use during use, the universality is achieved, the influence of loop change is avoided, the sequence of branch line connection is only required to be changed during loop change, and products are not required to be scrapped and changed. On the basis of generalization and standardization, the connector can be manufactured and applied in a large scale, thus forming scale effect and having extremely low cost.
