Description

Technical Field:

[0001] The utility model relates to the technical field of automotive optoelectronic signal transmission, and particularly refers to an optoelectronic signal composite system. Background Art:

[0002] With the development of society, cars have gradually become a standard configuration for ordinary families.

[0003] An automotive camera, as the name implies, is a camera used for cars or other ground motor vehicles. Automotive cameras are widely used in the automotive field. They can be used to detect the distance between the vehicle body and obstacles, and transfer it to a display screen for image display or alarm the driver through a buzzer, so that the driver can understand the road conditions in front of and behind the vehicle body and avoid collisions with obstacles.

[0004] Moreover, there are more and more electronic devices on cars. These electronic devices need to be connected to a junction box for centralized control to ensure the normal operation of the internal functions of the car.

[0005] The Chinese utility model patent with the application number 201920901151.2 discloses an automotive junction box, which includes a junction box body, a printed circuit board, a fixed sandwich layer and a rear cover. The printed circuit board includes a first circuit board and a second circuit board. The fixed sandwich layer includes a first fixed sandwich layer and a second fixed sandwich layer. Inside the junction box body, the first fixed sandwich layer, the first circuit board, the second fixed sandwich layer, the second circuit board and the rear cover are sequentially arranged from inside to outside. A plurality of connecting columns are arranged around the junction box body. The connecting columns include wall-attached connecting columns, raised connecting columns and combined connecting columns. Two combined connecting columns are arranged on the top of the junction box body. Two wall-attached connecting columns and one raised connecting column are sequentially arranged on both sides of the junction box body from top to bottom. Two raised connecting columns are arranged at the bottom of the junction box body. This junction box is convenient for installation through the connecting columns with different structures on the outside, and has a firm structure and is not easy to loosen.

[0006] The above-mentioned junction box has the following deficiencies: Combining the patent (application number 201920901151.2) Figure 1 and Figure 5 as shown, the front of the automotive junction box has a plurality of slots for plugs to be inserted. A plurality of conductive metal sheets are arranged in the slots, and the conductive metal sheets are welded and fixed on the same PCB board. The automotive junction box with this structure can only achieve electrical connection through the conductive metal sheets, and it cannot achieve optical signal transmission. For example, it cannot transmit the signals collected by the automotive camera to the automotive junction box by optical transmission; at the same time, because the conductive metal sheets are welded and fixed on the same PCB board and cooperate with the slots on the front of the automotive junction box to form a plurality of socket structures with different shapes, but it cannot be disassembled and replaced easily, and it is not convenient to use.

[0054] In summary, in the present utility model, the first optoelectronic signal hybrid socket 1 of the first optoelectronic signal transmission line 100 is installed in the insertion position 501 of the junction box 5, and the first optoelectronic signal hybrid socket 1 is directly used for plugging and installing with the second optoelectronic signal transmission line 200, rather than being directly plugged and fixed on the junction box 5. As a result, the first optoelectronic signal hybrid socket 1 of the first optoelectronic signal transmission line 100 can be disassembled and replaced relative to the junction box 5, and can better adapt to the second optoelectronic signal hybrid plug 2 of the second optoelectronic signal transmission line 200, so that the second optoelectronic signal hybrid plug 2 is not restricted during use and is more convenient to use. At the same time, in the present utility model, the second optoelectronic signal hybrid plug 2 is plugged and conducted with the first optoelectronic signal hybrid socket 1, thereby connecting the first optoelectronic signal transmission line 100 and the second optoelectronic signal transmission line 200 to achieve electrical connection (power transmission) and optical connection (optical signal transmission), and further realizing the composite optoelectronic signal transmission to the camera, which is more convenient to use. Moreover, the optoelectronic signal is adopted, and the signal is more stable, ensuring the communication quality.
