2. Description of the Related Art Electric wiring used for electric control devices, etc.
It is widely practiced to attach a short double-cut tube (hereinafter, referred to as a wiring identification tube) on which an identification code is printed to both ends for identification.

The wiring identification tube used for such an application is made of soft vinyl chloride or the like, and can be slidably inserted into the outer diameter of the electric wiring including the insulating coating, and further, during wiring work. A diameter that does not move carelessly is used.

The wiring identification tube is usually attached to the electric wiring by hand, but in order to automate this, a positioning header for holding and positioning the wiring identification tube without deforming it. Is also proposed.

[0005] This one has a pair of block bodies, each having a grip hole corresponding to the outer diameter of the wire identification tube formed at the center thereof and which can be opened / closed in a split state. The block body is opened to place the wire identification tube in the grip hole. Receive, close the block body and position the received wiring identification tube,
After the electric wiring is inserted into the positioned wiring identification tube, the block body is opened again and the block is discharged. The inner diameter of the grip hole is set slightly larger than the outer diameter of the wire identification tube so that the wire identification tube is not deformed.
It can be fixed by applying a negative pressure from the outside through a plurality of suction nozzles opening in the gripping hole in the radial direction.

[0006]

According to such a conventional technique, the wiring identification tube is inserted into and removed from the gripping hole by opening and closing the pair of block bodies.
There is a problem in that the opening operation time and the closing operation time of the block body are required for each repeated operation cycle, and the overall operation cannot be speeded up. Also, since the diameter of the matching wire identification tube is fixed to the size of the grip hole, when handling wire identification tubes of different standards,
There was also a problem that the block body had to be replaced, and the setup work was complicated.

Therefore, an object of the present invention is to form a V-shaped groove in the block main body and maintain a negative pressure in the V-shaped structure to position the wiring identification tube with high accuracy without deformation and to insert and remove it. It is an object of the present invention to provide a wiring identification tube positioning header that can be used for a wide range of wiring identification tubes of different standards in a very short time.

[0008]

The structure of the present invention for achieving the above object is to provide a block main body with a connection port for connecting a negative pressure pipe, a V-shaped groove for holding a wiring identification tube, and a V-shaped groove. The gist of the invention is to form a nozzle hole that opens at the valley portion of the nozzle and communicates with the connection port.

A plurality of nozzle holes can be provided along the V-shaped groove, or can be formed in a slit shape. Further, an equalizer groove can be provided in the V-shaped groove, and the nozzle hole can be opened in the equalizer groove.

[0010]

According to the structure of the present invention, the block body can be connected to the negative pressure pipe through the connection port, and at this time, since the nozzle hole is opened in the valley portion of the V-shaped groove, The block body can adsorb the wiring identification tube through the V-shaped groove. The adsorbed wiring identification tube can be surely positioned by making line contact with the slope forming the V-shaped groove, and moreover, the V-shaped groove is expanded only on one side, so that the wiring identification tube is , Regardless of its size, it is possible to stably attract and position. The adsorbed wiring identification tube can be easily released by removing the negative pressure.

When a plurality of nozzle holes are formed in the V-shaped groove, negative pressure can be applied to a plurality of positions in the longitudinal direction of the wiring identification tube, so that the block body holds the wiring identification tube more stably. can do.

Further, if the nozzle hole is formed in a slit shape, the wiring identification tube can be more stably sucked by the single nozzle hole.

If an equalizer groove is provided in the V-shaped groove, the equalizer groove can even out the negative pressure applied to the wire identification tube, so that the partial deformation of the wire identification tube to be adsorbed can be further reduced. it can.
