BRIEF DESCRIPTION OF THE DRAWINGS FIG.
This will be described with reference to FIG. FIG. 1 is a plan view showing an embodiment of the jumper wire assembly according to the present invention before mounting, and FIG. 2 is a perspective view showing the jumper wire assembly shown in FIG. 1 in a mounted state.

A jumper wire assembly 11 shown in FIG. 1 shows a state before mounting for automatic insertion on a printed circuit board 10 by an automatic insertion device, and a pair of piers standing on a conductor pattern on the printed circuit board 10. A jumper wire 1 including a bridge portion 2 and a bridging portion 3 connecting the pair of pier portions 2 extends straight, and both ends thereof are adhesively held by a taping portion 4 for automatic insertion. A pair of insulating spacers 12 made of a spherical insulator are fixed to the bridging portion 3 of the jumper wire 1 so as to face each other with a predetermined space therebetween. The jumper wire 1 between the insulating spacers 12 and 12 is covered with a surface plating 13. I have. The insulating spacer 12 has a jumper wire insertion hole 12a penetrating the center portion and a jumper wire insertion hole 12a
And a cut-off line 12b leading to a spherical insulator. The inner diameter of the jumper wire insertion hole 12a is slightly smaller than the outer diameter of the jumper wire 1;
b may have a width that allows the introduction of the jumper wire 1.

The insulator spacer 12 shown in this embodiment
Is made of a synthetic resin material, etc., which is easy to mold and has heat resistance, and is shaped into a sphere.The surface has some elasticity so that it can withstand some external impact. ing. Further, since the insulating spacer 12 can be expanded right and left across the cut line 12b, when the insulating spacer 12 is mounted on the jumper wire 1, the insulating spacer 12 expanded left and right across the cut line 12b is assembled to the jumper wire 1. Can be. In addition, as the insulating spacer 12,
Not only a synthetic resin material but also a material obtained by processing a rubber material or the like can be used.

When the jumper wire assembly 11 is to be inserted into a predetermined position on the printed circuit board 10 by an automatic insertion device, first, the jumper wire 1 having both ends adhered and held to the automatic insertion taping portion 4 is removed. Cut at the boundary with the part 4. Cut jumper wire assembly 1
Reference numeral 1 denotes a bridge pier 2 which is bent substantially at a right angle from both ends by a predetermined length to form a bridge pier 2, and left and right bridge piers 2 are inserted into through holes of the printed circuit board 10 in a state where the bridge pier 2 is formed from a linear shape to a concave shape. . The tip of the pier 2 penetrating the through-hole is turned inward and locked on the back surface of the printed circuit board 10.

In this case, the jumper wire assembly 11 is inserted so as to straddle the other already inserted jumper wires 5 and 6, but the pier 2 of the jumper wire 11 is
Immediately before being inserted and locked in the through hole, the insulating spacer 12 contacts and locks the surface of the printed circuit board 10.
Therefore, the jumper wire 1 at a portion sandwiched between the insulating spacers 12 is separated from the printed circuit board 10 by a radial distance of the insulating spacers 12. That is, jumper wire 1
Is a printed circuit board 10 formed by a pair of insulating spacers 12.
The other jumper wires 5 and 6 are straddled in a state where the height of the jumper wires 5 and 6 is maintained, and the three-dimensional intersections with the other jumper wires 5.6 do not contact each other.

As described above, the jumper wire assembly 11
A pair of insulating spacers 12 are separated from each other by a predetermined distance between the bridging portions 3 of the jumper wire 1 including the pair of pier portions 2 erected on the printed circuit board 10 and the bridging portions 3 connecting the pair of pier portions 2. The jumper wires 1, 5, and 6 intersect in a three-dimensional crossing manner in the air in a non-contact manner. And each crossing jumper line 1
Height can be arbitrarily set according to the size and shape of the insulating spacer 12 to be used, whereby complicated wiring is possible even on the printed circuit board 10 having a limited plane space, and the space efficiency is increased accordingly. Since the printed circuit board 10 having a complicated conductive pattern can be easily designed, and especially the conductive patterns for transmitting and receiving a large current can be securely connected to each other by the jumper wires 1. Reliability can be improved. Furthermore, when the jumper wire 1 is automatically inserted by the automatic insertion device, the insulating spacer 1 is not affected by any impact.
Since 2 functions as a cushioning material, deformation of the jumper wire 1 can be prevented.

Further, since the jumper wire 1 is formed of a plated wire in which a portion sandwiched between a pair of insulating spacers 12 is covered with a surface plating 13, the jumper wire 1 straddles the other jumper wires 5 and 6. When mounted in the above manner, the jumper wire 1 straddling the other jumper wires 5 and 6 is bent or deformed by a physical shock despite being maintained at a height by the insulating spacer 12. Even if the dropped part comes into contact with another jumper wire 5 or 6, a short circuit accident does not occur immediately, and erroneous contact due to the three-dimensional cross connection by the insulating spacer 12 can be safely dealt with.

Further, the insulating spacer 12 is made of a spherical insulator having a jumper wire insertion hole 12a passing through the center portion and a cut line 12b extending from the outer peripheral portion to the jumper wire insertion hole 12a. Spacer 1
When assembling 2, cut the jumper wire 1
It is only necessary to guide the jumper wire 1 through the insulating spacer 12 by guiding the jumper wire 1 along the jumper wire insertion hole 12a. Therefore, it is easy to assemble the spherical insulator to the jumper wire 1 and once assembled. Even if the spherical insulator rotates around the jumper wire insertion hole 12a, the spherical insulator keeps its height with the printed circuit board 10 with its spherical radius, so that the original function can be reliably performed.

In the above embodiment, the insulating spacer 1
Although the case where a spherical insulator is used as 2 is taken as an example, the insulating spacer 12 is a disc-shaped insulator having a jumper wire insertion hole passing through the center portion and a cut line extending from the outer peripheral portion to the jumper wire insertion hole. Can also be configured. When assembling an insulating spacer to a jumper wire, the insulating spacer made of this disc-shaped insulator also guides the jumper wire along the cut line into the insulating spacer, and simply sets the jumper wire insertion hole so that the jumper wire can be inserted. Therefore, it is easy to assemble the disc-shaped insulator with respect to the jumper wire, and even if the disc-shaped insulator once assembled is rotated around the jumper wire insertion hole, the disc-shaped insulator can be attached to the board with the radius of the disc. Since the height is maintained, the original function can be reliably performed.

In the above embodiment, the insulating spacer 1
Although the detachable 2 is used for the jumper wire 1 along the cut line 12b, an insulating spacer molded to the jumper wire 1 without the cut line 12b may be used. Further, as the jumper wire 1, the one sandwiched between the pair of insulating spacers 12, 12 is made of a plated wire covered with surface plating, but the plating of the plated wire portion can be omitted. is there.

[0019]

As described above, according to the jumper wire assembly of the present invention, a bridge of a jumper wire having a pair of piers standing on a substrate and a bridge connecting the pair of piers is provided. In the part, a pair of insulating spacers are fixed to face each other with a predetermined spacing therebetween, and the height is maintained by interposing between the insulating spacers and the substrate. It is possible to intersect in a state, and the height of each intersecting jumper line can be arbitrarily set according to the size and shape of the insulating spacer to be used, so that even a substrate with limited plane space is complicated. Wiring is possible, space efficiency can be improved accordingly, and printed circuit boards with complex conductive patterns can be easily designed, especially between conductive patterns that send and receive large currents. Since jumper wires can be connected to each other, the reliability of the circuit design can be improved.In addition, when the jumper wire is automatically inserted by the automatic insertion device, the insulating spacer functions as a cushioning material even if any impact is applied, An excellent effect is obtained such that deformation of the jumper wire can be prevented.

Further, since the jumper wire is formed of a plated wire in which a portion sandwiched between a pair of insulating spacers is covered with surface plating, when the jumper wire is mounted so as to straddle another jumper wire, Despite the fact that the jumper wire straddling another jumper wire is maintained at a height by the insulating spacer, the part that has been bent or deformed by physical impact contacts the other jumper wire. However, the short-circuit accident does not occur immediately, and it is possible to safely cope with erroneous contact caused by the three-dimensional cross connection by the insulating spacer.

Further, since the insulating spacer is made of a spherical insulator having a jumper wire insertion hole passing through the center portion and a cut line extending from the outer peripheral portion to the jumper wire insertion hole, when the insulating spacer is attached to the jumper wire, It is only necessary to guide the jumper wire along the cut line into the insulating spacer and make the jumper wire insertion hole a state where the jumper wire can be inserted.Therefore, it is easy to assemble the spherical insulator to the jumper wire, and once assembled. Even if the spherical insulator rotates around the jumper wire insertion hole, it keeps the height with the board with the radius of the sphere,
This has the effect that the original function can be reliably performed.

Furthermore, since the insulating spacer is made of a disc-shaped insulator having a jumper wire insertion hole passing through the center portion and a cut line extending from the outer peripheral portion to the jumper wire insertion hole, the insulating spacer is attached to the jumper wire. If
It is only necessary to guide the jumper wire along the cut line into the insulating spacer, and make the jumper wire insertion hole a state where the jumper wire is inserted. Therefore, it is easy to assemble the disc-shaped insulator to the jumper wire, and once assemble Even if the disc-shaped insulator is rotated around the jumper wire insertion hole, it keeps its height from the board with the radius of the disc, so that it can reliably perform its original function. To play.
