Abstract
The invention discloses a composite type flat cable. The composite type flat cable comprises two cable cores and a signal line. An inner protective sleeve is wrapped outside each cable core. A connection ring is connected between the inner protective sleeves outside the two cable cores in an integrated mode. The signal line is located in the connection ring. The inner protective sleeves outside the two cable cores and the connection ring are wrapped in a flat sheath. Steel bands are arranged in the flat sheath and located on the periphery of the two cable cores. According to the composite type flat cable, the structure is simple, the cable cores in the composite type flat cable are connected through the connection ring, and the overall tensile property is improved; in addition, due to the fact that the signal line is arranged in the connection ring, the signal line is protected; meanwhile, the steel bands are arranged around the cable cores, and therefore the overall strength is improved.
