Technical Field

[0001] The utility model relates to the technical field of commercial vehicle manufacturing, and in particular to a commercial vehicle chassis wiring cable quick-insertion structure. Background Art

[0002] The electrical appliances of commercial vehicles are connected by wiring harnesses. The wiring harness of the whole vehicle runs through the whole vehicle from beginning to end. It is responsible for the information transmission between the various electrical components of the vehicle and connects the controller with various electrical appliances to form a vehicle control system. In the process of wiring harness design and layout, due to the different wheelbases of commercial vehicle chassis, the types, quantities and lengths of wiring harnesses are different. There are many wiring harness connectors, and due to the limitations of the wiring position of the wiring harness, the switching angle is difficult to control, resulting in the inability to reasonably switch the wiring harness and the connector. Summary of the invention

The wiring harness replaces the original wiring harness and is quickly connected to the wiring harness through a piercing method via a connector, replacing the original plug-in connection. The piercing method connection can be made at a reasonable position, avoiding the difficulty in switching the wiring harness due to position limitations.

[0016] like Figure 1 As shown, a commercial vehicle chassis wiring cable quick-plug structure includes a wiring cable 2, a connector 1 and a connector base 3; the connector 1 is inserted into the wiring cable 2 to contact the wire 21 provided in the wiring cable 2, and is connected to the connector base 3.

[0017] The connector 1 is provided with a plurality of terminals 11 , the upper ends of the plurality of terminals 11 are connected to the wiring harness 12 , and the lower ends of the plurality of terminals 11 are inserted into the flat cable 2 and contact with the corresponding wires 21 on the flat cable 2 .

[0018] A connecting column 13 is provided at the lower edge of the connector 1 , and the connecting column 13 is connected to the connector base 3 .

[0019] A pin hole 31 corresponding to the connecting column 13 is provided at the edge of the connector base 3 , and the connecting column 13 is inserted into the pin hole 31 to be connected to the connector base 3 .

[0020] The widths of the connector base 3 and the connector 1 are the same, and the widths of the connector base 3 and the connector 1 are greater than the width of the flat cable 2 .

[0021] The widths of the connector base 3 and the connector 1 are the same, which can make the two fit more closely; and the widths of the connector base 3 and the connector 1 are greater than the width of the flat cable 2, so that the connecting column 13 provided at the lower edge of the connector 1 is inserted into the column pin hole 31 from both sides of the flat cable 2, thereby realizing the connection between the connector base 3 and the connector 1, and preventing the flat cable 2 from being pierced by the connecting column 13, causing a short circuit of the wire 21 provided in the flat cable 2.

[0022] The utility model adopts this flat cable 2 to replace the original wiring harness, which can be optimized for the topological design link, and can be cut to the required length according to the actual wheelbase length of the vehicle and the layout position of some chassis electrical modules. The flat cable 2 is inserted into the flat cable 2 by piercing through the terminal 11 of the connector 1. After the piercing connection, the terminal 11 is connected with the wire 21, and the connecting column 13 provided by the connector 1 is matched and fixed with the column pin hole 31 provided by the connector base 3 to complete the transfer of two groups of flat cables 2, thereby reducing the cost of using the wiring harness. Cutting according to the required length and the quick piercing form can reduce the assembly risk of redundant or short length of the wiring harness. The connector 1 with the terminal 11 can be directly inserted into any position of the flat cable 2 to complete the connection and conduction, realize the piercing connection, optimize the design and improve the assembly efficiency.
