Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of light-emitting cable, specifically to a mine light-emitting cable. BACKGROUND

[0002] The light-emitting cable is suitable for open-pit mine cable, and the main function is safety warning. The cable is irregularly laid and moves back and forth with the equipment without a protection device. The light-emitting cable is more eye-catching, which prevents the safety accidents caused by the rolling of vehicles and equipment on the cable. The light source of the light-emitting cable mainly comes from the silica gel light strip arranged inside. In the cable, the silica gel light strip is arranged in a mode of being wound on the power line or being laid parallel to the power line. In the use process, because the silica gel light strip is thin and soft, the winding and bending operation of the cable can easily cause the silica gel light strip to move greatly relative to the power line or to be twisted by many turns. The circuit in the light strip is extruded by the power line or is twisted and deformed by itself, which causes the circuit to be invalid and affects the light-emitting warning effect. SUMMARY

[0003] The utility model solves the technical problem of providing a mine light-emitting cable in which the silica gel light strip is not easy to move greatly relative to the power line during the winding and bending of the cable.

[0015] As an embodiment of the utility model, one side of the flexible circuit board is fixed in the accommodating cavity through a PET adhesive tape.

[0016] As an embodiment of the utility model, the limiting filler is provided with a ground wire limiting groove corresponding to the ground wire, and the ground wire is arranged in the ground wire limiting groove.

[0038] Participate Figure 3 The light-emitting assembly comprises the flexible circuit board 104 arranged in the accommodating cavity 102 and the lamp beads 105 arranged on the flexible circuit board 104, and the wire harness is connected between two adjacent light-emitting assemblies, and the length of the wire harness is greater than the spacing between the two adjacent light-emitting assemblies, so that the wire harness will not be pulled off due to insufficient length when the cable is bent and deformed.

[0039] The light-emitting form of the lamp beads 105 is of two types, one is plug-in type, and the lamp beads can emit light after the 220V or 24V power supply is turned on, and the other is electromagnetic induction light-emitting, that is, as long as the power line 200 is connected to the power supply, the special lamp strip can emit light through electromagnetic induction in the absence of load, without plugging in.

[0040] One side of the flexible circuit board 104 is fixed in the accommodating cavity 102 through the PET adhesive tape 106 to avoid the problem of friction damage of the flexible circuit board 104 caused by the displacement of the flexible circuit board 104 relative to the silica gel sleeve 101.
