Description

Technical Field

[0001] This utility model relates to an automotive combination switch, belonging to the technical field of automotive combination switches. Background Technology

[0002] In existing automotive combination switches, the wiring inside the levers is connected to each contact via a single wire, with the other end of the wire connected to the main circuit board of the switch. This connection method results in messy wiring, difficult wiring, and a tendency for the wires to pull against each other, leading to malfunctions. In addition, the upper and lower clamps of existing levers are usually connected by clips or screws. Clips may not be properly engaged or may have large gaps, while screws require a large amount of structural space and affect the appearance.

[0003] In other words, there is a need for an automotive combination switch that can connect the contacts to the main circuit board of the switch in a simpler, more convenient and stable way, while ensuring a secure connection between the upper and lower clamps. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an automotive combination switch that can connect the contacts to the main circuit board of the switch in a simpler, more convenient and stable way, while ensuring a stable connection between the upper and lower clamps; it can overcome the shortcomings of the prior art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] This utility model discloses an automotive combination switch, which includes an integrated mounting base. A lever is provided on the left and right sides of the integrated mounting base. Each lever is equipped with a rotary switch, an upper clamping plate, and a lower clamping plate. The upper and lower clamping plates are connected by fastening pins. The rotary switch is connected to a main circuit board for the switch housed within the integrated mounting base via a flexible wiring harness.

[0007] As mentioned above, the upper and lower clamping plates are provided with pin holes for fastening pins at corresponding positions, the fastening pins are provided with knurling, and the inner wall of the pin hole is provided with protrusions that cooperate with the knurling.

[0008] The rotary switch described above includes a drive shaft located inside the lever, a retaining ring located at the end of the drive shaft, and a knob. Contacts are distributed on the retaining ring, and contact pieces that cooperate with the contacts are provided on the knob. The contacts are connected to a flexible wire harness.

[0009] The aforementioned integrated mounting base is provided with PCBA pin headers, which include a circuit board and pins. The circuit board has sockets, and the pins engage with the sockets.

[0010] As mentioned above, the upper end of the pin is provided with a pre-tightening fisheye structure that cooperates with the socket.

[0011] As mentioned above, the pin is equipped with a limiting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model utilizes multiple flexible wire harnesses that can be individually connected to the contacts on a rotary switch. At the same time, the flexible wire harness can solve the problems of messy wiring and high failure rate of existing single wires. Furthermore, by connecting the upper and lower clamping plates with fastening pins, the stability of the connection between the upper and lower clamping plates can be improved, which helps to prevent loosening.

[0014] 2. The upper and lower clamping plates are provided with pin holes for fastening pins at corresponding positions. The fastening pins are knurled, and the inner wall of the pin hole is provided with protrusions that cooperate with the knurling. In this way, the upper and lower clamping plates can be connected by the fastening pins during installation.

[0015] 3. PCBA pin headers include circuit boards and pins. The circuit boards have sockets, and the pins engage with the sockets. The method of connecting the pins to the circuit boards facilitates the installation, removal, and replacement of individual pins, which helps improve efficiency and reduce potential quality issues.

[0016] 4. The upper end of the pin is provided with a pre-tightening fisheye structure that cooperates with the socket. The fisheye structure is conducive to pre-tightening and preventing dislodgement. At the same time, the pin is provided with a limiting block, which makes it easy for the pin to be installed in place.

It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0028] Example 1

[0029] like Figures 1-5 As shown, this utility model discloses an automotive combination switch, which includes an integrated mounting base 1. A lever 2 is provided on the left and right sides of the integrated mounting base 1. A rotary switch 3, an upper clamping plate 4, and a lower clamping plate 5 are provided on the lever 2. The upper clamping plate 4 and the lower clamping plate 5 are connected by a fastening pin 6. The rotary switch 3 is connected to a main switch circuit board provided inside the integrated mounting base 1 via a flexible wire harness 7. Specifically, the rotary switch 3 includes a drive shaft 9 located inside the lever 2, a fixing ring 10 located at the end of the drive shaft 9, and a knob 11. Contacts are distributed on the fixing ring 10, and a contact mechanism that cooperates with the contacts is provided on the knob 11. The contact point is connected to the flexible wire harness 7. The connection end of the flexible wire harness 7 and the fixing ring 10 is provided with a collar. The collar is sleeved on the drive shaft 9 and fixed to the fixing ring 10 by screws. The other end of the flexible wire harness 7 is connected to the main circuit board of the switch. This structure allows multiple wires of the flexible wire harness 7 to be connected to the contacts on the rotary switch 3 respectively. At the same time, the flexible wire harness 7 can solve the problems of messy wiring and high failure rate of existing single wires. In addition, the upper clamping plate 4 and the lower clamping plate 5 are connected by the fastening pin 6, which can improve the stability of the connection between the upper clamping plate 4 and the lower clamping plate 5 and help to prevent loosening.

[0030] Furthermore, pin holes 8 for fastening pins 6 are provided at corresponding positions on the upper clamping plate 4 and the lower clamping plate 5. Knurling is provided on the fastening pin 6, and protrusions that cooperate with the knurling are provided on the inner wall of the pin hole 8. In this way, the upper clamping plate 4 and the lower clamping plate 5 can be connected by the fastening pin 6 during installation. At the same time, the knurling on the fastening pin 6 and the protrusions on the inner wall of the pin hole 8 cooperate with each other to further prevent the upper clamping plate 4 and the lower clamping plate 5 from loosening during use.

[0031] Example 2

[0032] like Figures 6-7 As shown, this embodiment improves the structure of the PCBA pin header 12 located in the integrated mounting base 1 based on embodiment 1. Specifically, the PCBA pin header 12 includes a circuit board 13 and a pin 14. A socket 15 is provided on the circuit board 13, and the pin 14 is engaged with the socket 15. The existing PCBA pin header is an integrated structure and uses a soldering method. The integrated structure cannot replace individual pins, resulting in high maintenance costs and complex soldering operations that are prone to causing cold solder joints. Therefore, by connecting the pin 14 to the circuit board 13, it is easier to install, remove, and replace individual pins 14, which helps to improve efficiency and reduce potential quality problems.

[0033] Furthermore, the upper end of the pin 14 is provided with a pre-tightening fisheye structure 16 that cooperates with the socket 15.
