[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a distribution line ends insulated apparatus and the wiring end insulation processing method for performing insulation treatment of the electric wiring end.
[0002]
[Prior art]
An electric wire in which the periphery of a conductive core wire is covered with an external coating such as plastic is used as wiring for various electric devices. In order to connect these wirings to the terminals of the electrical equipment, connecting tools such as crimp terminals are often attached to the terminal ends of the wirings. In order to prevent an electrical short circuit from occurring when the outer sheath of the wiring end is peeled off to attach a crimping terminal, etc., glass fiber, plastic, rubber Insulation is performed using an insulating tube made of an insulator such as paper or cloth.
[0003]
FIG. 7 shows the state of insulation treatment at the end of the wiring. The wiring 10 has a structure in which an inner core wire 12 is covered with an outer sheath 14. In order to obtain electrical contact, the outer covering 14 of the end portion 16 of the wiring 10 is peeled off, and the crimping terminal 18 is attached by crimping the caulking portion 20. At this time, the exposed portion 22 where the core wire 12 is exposed from the caulking portion 20 to the terminal portion of the outer coating 14 is left. The exposed portion 22 comes into contact with the exposed portion 22 of the other wiring 10, etc., and the electrical insulation characteristics are deteriorated, sometimes causing an electrical short circuit.
[0004]
Therefore, an insulating process such as winding an insulating tape made of an insulating material around the exposed portion 22 or covering an insulating tube is performed.
[0005]
FIG. 8 shows the state of the end of the wiring that has been insulated using the insulating tube. 8 (a) shows a perspective view of the appearance, FIG. 8 (b) shows a perspective view of a transmission. By attaching the insulating tube 24 around the exposed portion 22 in FIG. 7 , the exposed portion 22 is completely electrically protected.
[0006]
[Problems to be solved by the invention]
However, when the insulating tube 24 is attached to the end portion 16, the wiring 10 is flexible, and the wiring 10 is curved, so that it is not easy to insert the end portion 16 into the insulating tube 24. Further, when the core wire 12 is formed by a collection of a large number of thin wires, each wire is caught on the end of the insulating tube 24, and the insulating tube 24 may not be smoothly mounted.
[0007]
In addition, due to the above-described difficulty, the automation of the insulation treatment at the end portion of the wiring has not been realized so far, and the insulation treatment of the end portion 16 has been performed manually.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, a wiring end insulating device in which an insulating tube is attached to a terminal end of a wiring, and one end is fixed and guide claws urged outwardly have a predetermined interval. In the case where the guide claw is closed using an insulating tube guide frame, the outer diameter is smaller than the inner diameter of the insulating tube , and the wiring is used when the guide claw is opened using the insulating tube guide frame.
