Description

Technical Field

[0001] The utility model relates to the technical field of electronic circuits, in particular to an integrated CANbus wire harness. Background Art

[0002] CAN Bus (Controller Area Network Bus) is fully called "Controller Area Network Bus Technology". It is a serial bus system that connects field devices (sensors, actuators, controllers, etc.) in a manufacturing plant and is oriented to broadcasting. It was initially developed by General Motors (GM) in the United States for the automotive industry and has increasingly appeared in the manufacturing automation industry. CAN Bus has various advantages, can achieve more control, display, and alarm functions, simplifies wiring, better eliminates potential safety hazards, and reduces the chance of spontaneous combustion caused by wire harness aging and wear.

[0003] The wire harness mainly plays a role in connecting various components in a product or system, ensuring the smoothness of the circuit and the normal operation of the system, and plays a crucial role in the reliability of the entire product or system. With the development of industrialization, manufacturers have higher and higher requirements for improving production efficiency, controlling production costs, and the reliability of products during the mass production process of products. Especially in agricultural machinery, heavy mining machinery, and construction machinery, the control system has become the mainstream, and the electrical components involved in the machinery are gradually increasing, and the interface circuits are becoming more complex.

[0004] In the system with CAN, the overall wire harness planning is restricted, the wiring is not flexible, and there are many wire harness ports, which are prone to errors during on-site construction. Therefore, it is necessary to provide an integrated CANbus wire harness to solve the above problems. Content of the Utility Model

[0005] To overcome the above disadvantages, the purpose of the utility model is to provide an integrated CANbus wire harness, which realizes the integration of the wire harness, avoids interference caused by too many wire harnesses, improves the overall circuit layout of the system, and maintains the stability of signal transmission.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: an integrated CANbus wire harness, including a PCB board and a male head installed thereon; the male head includes a row of lead terminals arranged along its length direction, and the welding ends on multiple lead terminals are welded to the upper surface of the PCB board one by one. The surface of the PCB board is respectively provided with an inductor, a resistor setting area, an integrated cable connection area, and a slide switch setting area.

[0007] Furthermore, the lead terminal is arranged in a Z shape, and its welding end is parallel to the upper surface of the PCB board. This effectively increases the contact area between the welding end of the lead terminal and the PCB board, ensuring that the welding end of the lead terminal and the upper surface of the PCB board can be fully welded, avoiding the phenomenon of short circuit of some lead terminals during use, and ensuring the service life of the integrated wire harness.

[0008] Furthermore, the inductor and resistor setting area includes a number of inductor placement platforms and resistor placement platforms that protrude from the surface of the PCB board for positioning the inductor body and the resistor body. Along its length direction, there are a number of welding bosses protruding from the surface of the PCB board, which are the same in number and corresponding in position to the lead terminals. During installation, both ends of the inductor body and the resistor body are welded to the PCB board through soldering. The settings of the inductor placement platform and the resistor placement platform can facilitate the staff to accurately position the welding positions of the inductor body and the resistor body. The setting of the welding bosses is used to position the lead terminals to be welded, avoiding the phenomenon of welding disorder caused by a large number of lead terminals, ensuring the stability of subsequent signal transmission, and reasonably distributing the layout on the PCB board.

[0009] Furthermore, a slide switch is provided in the slide switch setting area, and a number of switch terminal positioning holes for inserting the switch terminals at the bottom of the slide switch are provided on the PCB board. The slide switch is detachably connected to the PCB board, and the switch terminal positioning holes can also provide positioning for the setting of the slide switch, making the installation of the slide switch more convenient.

[0010] Furthermore, the male head includes a front cover and a rear cover that cooperate with each other. The lead terminal is arranged between the front cover and the rear cover. After assembly, the lower surface of the rear cover abuts against the upper surface of the PCB board, and the front cover abuts against the side of the PCB board. At both ends in the length direction of the male head, rivet grooves penetrating through it are provided along its width direction.

[0011] Furthermore, a protective inner shell is covered on the PCB board, and a protective outer shell is covered outside the protective inner shell and on the male head. On both the protective inner shell and the protective outer shell, screw insertion holes corresponding in position and matching in size with the rivet grooves are provided for the horizontal insertion of locking screws. On the protective inner shell and the protective outer shell, there are also switch notches that cooperate with the slide switch. The protective inner shell and the protective outer shell can protect and fix the PCB board and the internal integrated cable, thereby extending their service life. The locking screw is inserted into the screw insertion hole and the rivet groove in sequence from the end of the protective outer shell away from the male head, and extends out of the rivet groove. When the male head is connected to other external connectors, after docking with the female head, it is locked and fixed through the locking screw to achieve the fixed connection between the two.

[0012] Further, through-holes for placing the harpoons on the male connector are formed at both ends of the PCB board in the length direction. The integrated cable connection area includes a plurality of welding holes penetrating the PCB board. The through-holes can accommodate the insertion and placement of the harpoons on the male connector, avoiding interference between the male connector and the PCB board when they are connected.

[0013] Advantages of the present utility model:

[0014] In the present utility model, the male connector cooperates with the PCB board. One end of the male connector is connected to another connector, and the other end is welded to the PCB board through the lead terminals thereon. Inductors, resistors, and switch signals are respectively integrated on the PCB board. There is no need to respectively butt the welding ends of the lead terminals to different connection wire harnesses. When the signal transmission requirements of the male connector are met, it can effectively avoid mutual interference caused by excessive wire harnesses, improve the overall circuit layout of the system, and maintain the stability of signal transmission.

Inductors, resistors, and switch signals are respectively integrated on the PCB board 9. Without separately docking the welding ends of the lead terminals 44 to different connection wire harnesses, when meeting the signal transmission requirements of the male connector 4, it can effectively avoid mutual interference caused by excessive wire harnesses, improve the overall circuit layout of the system, and maintain the stability of signal transmission.

[0024] The lead terminal 44 is arranged in a Z shape, and its welding end is parallel to the upper surface of the PCB board 9. It effectively increases the contact area between the welding end of the lead terminal 44 and the PCB board 9, ensures that the welding end on the lead terminal 44 and the upper surface of the PCB board 9 can be fully welded, avoids the phenomenon of short - circuit of some lead terminals 44 during use, and ensures the service life of the integrated wiring harness.
