The various functional wires are fed into the housing 120 of the splitter 12. It can be understood that the third cable 33 and the housing 120 of the splitter 12 can be fixedly connected to the first cable 31, the second cable 32 and the housing 120 of the splitter 12 in the same manner. In some embodiments, the fixed connection method may include the third cable 33 being fixedly connected to an additional connection hole by using an additional engagement mechanism (not shown). The engaging mechanism forms a passage (not shown) at the further connecting hole such that the third cable 33 can only extend into the housing 120 unidirectionally, when reaching a defined distance, the engaging mechanism will prevent the third cable 33 from continuing to protrude into the housing 120. In this case, the third cable 33 is also restricted from moving outside the housing 120 and the third cable 33 is fixedly connected to the additional connecting hole.
Within the housing 120 of the splitter 12, the respective functional wires respectively covered by the first cable 31, the second cable 32, and the third cable 33, will be connected one by one to form a circuit for a predetermined function. As a result, by using the splitter 12, on-site pre-wiring can be avoided.
