Please refer to fig. 1, and if necessary, fig. 2 to 7. The connection harness structure 100 includes at least one connection circuit board 10, at least two cables 20, and an SR structure 30. Opposite ends of each connection circuit board 10 are provided with corresponding electric connection keys. At least two cables 20 are respectively connected to the electric connection keys at opposite ends of the connection circuit board 10. The SR structure 30 comprises a prefabricated protective housing 31 and a mounting portion 32 disposed on the protective housing 31, the protective housing 31 has a receiving cavity 301 penetrating through opposite ends of the protective housing 31, and the mounting portion 32 comprises at least a mounting body disposed on an outer edge of the protective housing 31; the connection circuit board 10 is disposed in the accommodating cavity 301, at least one of the at least two cables 20 extends from one end of the accommodating cavity 301, and the other cables 20 of the at least two cables 20 extend from the other end of the accommodating cavity 301.
The connection circuit board 10 is understood herein to be a PCB board with electrical connection keys. The electrical connection key is understood herein to be a soldering point or a metal soldering pad, such as the electrical connection keys 11, 12, 13, 14 shown in fig. 7 of fig. 5, etc. Wherein, the PCB board is internally provided with connecting circuits which are respectively connected with the corresponding electric connecting keys at the two ends. The cables 20 are connected to the electric connection keys at opposite ends of the connection circuit board 10, which is understood to mean that the ends of the cables 20 are soldered to the corresponding electric connection keys.
The cable 20 may be a cable having one core in the middle, or may be a cable having a plurality of insulated cores. The cable has an insulating layer or coating outside the core. The insulating layer, the coating, and the like outside the core of the cable 20 may be a hard structure such as PVC, SR-PVC, or a flexible structure such as teflon, PE, or elastomer.
It should be understood that, taking the cables 21 and 22 (such as shown in fig. 1) at two ends of the connection circuit board 20 as an example, each wire core in the cable 21 at one end of the connection circuit board 20 may be soldered to one electrical connection key at the end of the connection circuit board 20 and connected to a corresponding electrical connection key at the other end of the connection circuit board 20 through a corresponding connection circuit inside the PCB board, and then connected to a corresponding wire core in the corresponding cable 22 through a corresponding electrical connection key, so as to realize transmission of electrical signals.
Here, the SR structure 30 is configured to have the prefabricated protective housing 31 and the mounting portion 32 provided on the protective housing 31, so that the SR structure 30 can be detachably mounted in other structures (such as a body housing), and problems occur in the connection harness structure 100 or the body housing of the electronic device having the connection harness structure 100, so that the connection harness structure 100 and the body housing can be detached, and then only the problematic connection harness structure 100 or body housing needs to be replaced, thereby facilitating maintenance and replacement, and being beneficial to reducing maintenance difficulty and cost.
The connection circuit board 10 is adopted to realize the switching of the cables at two ends in the SR structure 30, so that the selection of the cables is not limited by an insulating layer and an outer cover which need a hard insulating structure such as PVC, but can have more different types of selections, such as a cable with a core outer insulating layer or a flexible structure which is externally coated with teflon, PE or elastomer. The cable can also be improved in various performances according to the material and structure of the cable, such as temperature resistance, swing resistance, torsion resistance, high frequency resistance and the like of the required connecting harness structure can be set according to the requirements. Compared with the mode of realizing the sealing of the connecting wire harness structure through waterproof glue in the related art, the problem that the waterproof glue is not firmly bonded with the cable insulating layer or the outer quilt can be well solved.
