In the power supply signal composite rope that the present embodiment two provides, holding wire 23, live wire 24 and ground wire 25 are uniformly distributed, and in three, the difference of both external diameters is less than 1mm arbitrarily.More preferred, the external diameter of live wire 24, ground wire 25 and holding wire 23 can equate, concentrates with further relieve stresses.Preferably, in the present embodiment two, holding wire 23 is two, and two holding wires 23 are crosswise with live wire 25 and ground wire 24 and distribute, and this distribution mode makes the structure of power supply signal composite rope more stable.
In current power supply signal mixing cable, holding wire 23, ground wire 25 and live wire 24 are common bundle structure (axis that is holding wire 23, ground wire 25 and live wire 24 is all parallel with the center line of whole power supply signal composite rope), this power supply signal composite rope is being subject to pulling easy generation turn-knob when connection module is connected, and then causes the joint of each cable in power supply signal mixing cable in turn-knob tensioned state.This state can cause the joint of ground wire 25, live wire 24 and holding wire 23 in discrete state, finally causes wiring operating difficulties.Meanwhile, the cable head of the joint of connection module being tightened at turn-knob is easy to be damaged under pulling.For head it off, in the power supply signal mixing cable that the present embodiment two provides, holding wire 23, live wire 24 and ground wire 25 distribute along the axis layer strand of power supply signal composite rope.The mode that holding wire 23, live wire 24 and ground wire 25 adopt layer strand to distribute, make whole power supply signal composite rope in the time suffering torsion, itself just there is the active force recovering along torsion direction, this finally can reduce the impact of torsion on each cable, and then operating difficulties and to the flimsy problem of connection module when reducing power supply signal composite rope and connection module being connected.
More preferred, the power supply signal composite rope that the present embodiment two provides also comprises screen 22, for shielding the impact of external electromagnetic signal on holding wire 23.Screen 22 depends on envelope and moulds in oversheath 21, and is coated on cable bundle.After power supply signal composite rope is connected with to connection module, screen 22, for being connected with ground wire 25, makes outside electromagnetic interference signal ground, can eliminate preferably outside electromagnetic interference signal.For this reason, preferred, screen 22 comprises the wrapped belt of semiconductor that is positioned at outer field braiding copper wire layer and be positioned at internal layer, and semiconductor twining package tape laminating invests on braiding copper wire layer, for wrapping cable bundle.After power supply signal composite rope is connected with to connection module, braiding copper wire layer is for being connected with ground wire 25, for electromagnetic interference signal is eliminated.
