JP5334027B1 - LAN cable spiral forming metal wire straight line forming tool - Google Patents

Abstract

PROBLEM TO BE SOLVED: To connect a spiral metal wire 13 to a connector plug, it is necessary to rub the spiral metal wire with a fingertip many times by a screwdriver or the like to make a straight line. The metal wire insulation coating and fingertips have been subjected to straight line molding with considerable stress. The present invention relates to a linear forming tool for a LAN cable helical metal wire that can easily form a helical metal wire 13 into a straight line.
SOLUTION: A spiral metal wire 13 is placed in a wire forming groove 7 of a linear molding machine lower plate 1 and crushed by a linear molding machine upper plate 8 to be planar molded with left and right meanders remaining. . By pulling the spiral metal wire 13 through the U-shaped groove 4, the left and right meanders are unwound on the wire forming wall surface 14, and the taper surface 5 for the lower plate of the linear shaper and the taper surface 10 of the upper plate of the linear shaper It is straightened by the surface and comes out as a straight line. This reduces the stress on the cables and fingertips, and enables stable and efficient linear molding work to be continued.

Description

  The present invention relates to a linear forming tool for a LAN cable helical metal wire, which can easily form a helical metal wire.

  As a conventional method, a method using a fingertip, a driver, a whale, or the like is known. When it is done with the fingertips, the twisted pair wires are each made of two spiral metal wires. I applied a screwdriver or a whale to the single wire, pushed and bent the wire to about 90 degrees, picked it up with a screwdriver or a fingertip and a fingertip, and pulled out the rubbing.

  When using a screwdriver or whale, open the gap on the sheath side of the twisted-pair wire a little by hand, insert a whale or thin screwdriver into the gap, and move the wire from the base of the wire toward the cut end. It was pulled away at once while rubbing. (See Non-Patent Document 1.)

  Because straight molding is not performed well due to tool usage, work method, individual differences, etc., there is an adverse effect on the terminal connection processing of the connector plug, and unstable situations such as poor connection and disconnection in the middle are occurring It was.

  As an example of twisting by twisting a twisted pair wire between chucks, there is one disclosed in Patent Document 1

  “General Catalog 2012 P454” Sanwa Supply Co., Ltd.

  Until the twisted-pair wire was unwound and the spiral of the spiral metal wire was unwound and straight-line molding was possible, there was no other way than rubbing and twisting back together. The work of pinching with the thumb and forefinger and putting pressure on the fingertip has considerable pain on the fingertip. In order to use a straight-line-formed single wire without twisting, the more the line was formed, the more damage to the fingertips occurred. A tool with less damage and a reduction in work time and certainty were desired.

  There are a method of inserting a screwdriver or whale through the gap between the twisted pair cables and pulling it out, or a method of pressing a helical metal wire against the screwdriver or whale and bending the wire with a fingertip. Twisting can be done quickly by applying the force of the fingertips, but the cable is spiral and has resistance, making the insulation of the wire thinner or scratched. The thing with very few these obstacles was calculated | required.

  Spiral metal wires that have insufficient linearity due to the force applied during linear molding are inserted into connector plugs and crimped. Inconvenience occurred, such as leaving. There has been a demand for stabilization of processing of a spiral metal wire.

  As a method of twisting the twisted pair wire by rotating it, there is a method of rotating the twisted pair wire between the chuck of the charging driver. Twisted pair wires have different twist intervals, so if the stop timing is delayed, the twist may return to the back of the sheath more than necessary, affecting communication performance. Since this method cannot be performed with one hand and takes time, a stable tool with high work efficiency has been demanded. (See Patent Document 1.)

  For example, peel off the sheath of a LAN cable having four pairs of twisted pair wires, break it into eight spiral metal wires, and put that one wire into the LAN cable spiral metal wire linear forming tool of the present invention. Can be easily straight-line molded.

  A linear molding machine lower plate magnet 6 is provided on the work surface of the linear molding machine lower plate 1, and a linear molding machine upper plate magnet 15 is provided on the linear molding machine upper plate 8. The magnets face each other with the same magnetic pole and are opened by the repulsive force of the magnetic pole. It has the effect of a spring that governs opening and closing, and eliminates obstructive projections from the work surface. The opening angle is determined by the opening angle stopper surface 3 of the linear molding machine lower plate 1 and corresponds to the holding of the linear molding machine upper plate 8.

  The spiral metal wire 13 is placed in the U-shaped groove 4 having a depth equal to or less than 130% of the diameter of the wire, and the tip is placed on the wire forming groove 7 having the same depth.

  When the spiral metal wire 13 is sandwiched between the linear molding machine lower plate 1 and the linear molding machine upper plate 8, the linear molding machine lower plate 1 is crushed by the wire molding groove 7 and has a planar shape with left and right meandering. At this time, the electric wire crushed by the wall of the electric wire forming groove 7 is shaped so as not to protrude outside.

  When the metal wires with left and right meandering shapes are pulled and passed between the U-shaped lectures 4 while being crushed, the left and right meanders are unwound by the wall surface 14 for forming the wire, and the taper surface of the lower plate of the linear molding machine 5 and the straight shaper upper plate taper surface 10 are protected. Thereby, work efficiency can be improved even if the number of parts is small.

  According to the present invention, there are effects of reducing fingertip damage, shortening the processing time for straightening a spiral metal wire, improving processing quality and stabilizing.
