Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube aligning jig. For example, when connecting a probe and a lead wire of a continuity inspection jig of a connector as an example of the tube, the probe and the lead wire are connected. The present invention relates to an alignment jig for handling such a tube.

[0002]

2. Description of the Related Art FIG. 12 shows an inspection jig for inspecting the continuity of a connector. This one is
Main body 5 for inserting and temporarily fixing connector 30 with electric wire W
0, a probe P mounted thereon, and a lead R connected thereto. The connection between the probe P and the lead wire R is wrapped in an insulating tube C. Main unit 5
Numeral 0 is formed of a soft material such as a synthetic resin so as not to damage the connector 30 inserted therein.

When manufacturing the above-described inspection jig, first, it is necessary to insert a contraction tube C into the terminal portion T of the lead wire R.

In the current operation, as shown in FIG. 13, a contraction tube C put in a tray is picked out by a finger and taken out and inserted into a lead wire R.

Then, the terminal T of the lead wire R into which the shrinkable tube C is inserted is connected to the probe P of the continuity inspection jig.
And the contraction tube C is connected to the terminal portion T of the lead wire R.
And the probe P of the main body, and heat is applied to the shrinkable tube C in that state to shrink it.
This is intended to insulate the connection portion from the outside.

[0006]

In the above operation, the shrinkable tubes C randomly placed in the tray are picked up one by one by hand, and the lead wire R is inserted therethrough. There is a poor workability in that the lead wire R is not easily inserted smoothly because it is crushed even by a slight pinching force.

[0007] In order to perform the above-mentioned work of attaching the shrinkable tube to the lead wire with good workability, the shrinkable tube C is aligned by using, for example, the alignment jig without pinching the shrinkable tube C with a finger. It is conceivable to perform the operation by applying a lead wire to the state.

[0008] Accordingly, an object of the present invention is to study mounting of a shrinkable tube on a lead wire using such an alignment jig, and to efficiently align tubes by the jig. Is to do.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention firstly arranges a tube efficiently by an alignment jig as described below, and makes it easy to take out the tube. The above problem was solved by forming a shape on the jig.

In the jig, an alignment groove in which a tube of a predetermined length and a diameter can be loosely inserted into the surface of the plate body is vertically and horizontally interposed in the width direction and the length direction through partition walls. A guide groove formed on a surface of a partition wall for partitioning the alignment groove in the longitudinal direction, coaxial with the alignment groove, connected to the alignment groove, and having a width smaller than the groove width of the alignment groove. Was formed.

[0011] With this arrangement, if the lead wire is moved toward the tube along the guide groove with respect to the tube which is fitted in the alignment groove and aligned, the lead wire naturally becomes a tube. Since the tube is inserted into the inside, it is possible to perform the operation of mounting the tube with good workability without the tube flapping as in the case where the tube is picked up by hand and the lead wire is inserted there.

Next, in the above structure, a plurality of projections are arranged on the surface of the partition wall in the length direction of the alignment groove at an interval longer than the length of the tube so that the tube can be aligned more efficiently. The arrangement of the projections is formed every other row of the partition wall in the longitudinal direction of the groove and is shifted by a predetermined distance in the width direction of the alignment groove.

[0013] In this case, the tube is rotated in the horizontal plane by the projection, so that the length direction thereof follows the groove. Therefore, the probability of falling into the alignment groove is increased, and the tube is aligned faster.

Further, a cover is provided which is detachable from the substrate and is formed by a side wall surrounding the periphery of the substrate, and the tube is put into a box formed by covering the substrate with the cover. If the tube is swung, the tube does not jump out of the board, and the tube that jumps on the board is bounced back on the inner surface of the cover and heads toward the board, so there is a high probability that the tube will fall into the groove. And the tubes are aligned faster.

In this case, furthermore, a ridge running in the depth direction is parallel to the inner surface of the side wall of the cover facing the length direction of the alignment groove along the circumferential direction of the side wall at an interval shorter than the length of the tube. In this case, the probability that the ridges are flipped in various directions toward the base further increases, so that the tubes can be aligned more quickly.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. The alignment jig for a shrinkable tube of this embodiment shown in FIG. 1 includes a substrate 1 having an alignment groove 2 into which the tubes are dropped and aligned, and a cover 6 which covers the substrate 1 and forms a box. . Both are formed of vinyl chloride.

The substrate 1 shown in FIGS. 1 and 2 is a rectangular plate body, on the surface of which is formed the alignment groove 2 into which the contraction tube of the target work of this embodiment can be loosely inserted. . The alignment grooves 2 are arranged so that their length directions are parallel to the short sides of the substrate 1 and are arranged in parallel at equal intervals along the long sides. A partition wall 3 is formed between the adjacent alignment grooves 2.

The arrangement of the alignment grooves 2 is such that the substrate 1
Are formed in such a manner that the alignment grooves 2 of each row are coaxially arranged in the short side direction.
It is divided by.

Further, as shown in FIG. 2, the alignment groove 2 is formed on the surface of a partition wall 4 which partitions the alignment groove 2 in the longitudinal direction.
Coaxially with the guide groove 4a having a depth smaller than the depth of the alignment groove 2 and a width smaller than the groove width of the alignment groove 2 at that depth.
Are formed. After the tube C is dropped into the alignment groove 2 and aligned, the guide groove 4a is used to insert a lead wire (see reference symbol R in FIG. 8) into the tube C in the alignment groove 2 along the guide groove 4a. Then, it serves as a guide for the lead wire R when the tube C is attached to the lead wire R.

Pan screws 5 are screwed into the surface of the partition wall 4 in the length direction of the alignment groove 2 of the tube C at equal intervals at an arrangement interval d longer than the length of the shrinkable tube C, and the head portion is partitioned. It protrudes from the wall surface. The pan screw 5
Are arranged in every other row of the partition wall 4 in a zigzag manner so as to be located just in the middle of the pan screw 5 of the adjacent partition wall 4 (the position of the pan screw 5 in FIG. 2 is d / 2). Has been established.

A cover 10 described below covers the peripheral portion of the substrate 1 so that a box 10 can be formed as a whole.

As shown in FIG. 1, the cover 6 is formed by integrating four side walls 6a into a rectangular shape.
As described above, the bottom inner peripheral surface of the side wall 6a covers the outer peripheral surface of the substrate 1 to form the box body 10 as a whole. The opposite long side wall 6 of the cover 6
On the inner surface of a, there are formed ridges 7 arranged at equal intervals in the depth direction along the longitudinal direction. The cross section of the ridge 7 forms a triangle, and the vertex thereof faces the inside of the cover 6. The protruding ridges 7 are provided to increase the probability that the tube that has not fallen into the alignment groove 2 in the initial vibration of the substrate 1 and that has reached the side wall 6a of the cover 6 will be repelled toward the alignment groove 2 when hitting the tube. . The spacing between adjacent ridges 7 is slightly shorter than the length of the shrink tube so that the shrink tube does not fit between the ridges 7.

When the cover 6 is placed on the substrate 1, the lower surface of the ridge 7 is placed on the periphery of the upper surface of the substrate 1.

A box 10 is formed by the above-described substrate 1 and cover 6 as shown in FIG. 3, and a handful of tubes C are put into the box 10, and as shown in FIG. Guide rod 21 laid over the open upper surface of the shrink tube tray 20
And vibrates in the longitudinal direction of the alignment groove 2 by sliding on the guide rod 21.

Then, the vibration causes the shrinkable tube C to be dropped into the alignment groove 2 and aligned. In the process, the shrinkable tube C is provided on the protrusion 7 of the side wall 6 a of the cover 6 and the surface of the partition wall 4. The pan head screw 5 plays a role of accelerating the alignment of the shrinkable tube C by the above-described operation as compared with the case where they are not provided.

When the user feels that all of the shrinkable tubes C have fallen into the alignment grooves 2, the vibration of the box 10 is stopped, and the cover 6 is removed as shown in FIG. 5, and as shown in FIG.
The extra shrink tubes C that are stacked on the shrink tubes C that have fallen into the alignment grooves 2 and are aligned are returned into the tray 20 so that only the aligned shrink tubes C are lined up on the substrate 1. (FIG. 7).

As shown in FIG. 8, the tubes C aligned on the substrate 1 are arranged along the guide grooves 4a on the surface of the partition wall 4 which partitions the alignment grooves 2 in the longitudinal direction. Insert the terminal part T of the lead wire R inside,

[0030]

As described above, according to the present invention, the tube is put on a substrate having a groove in which the tube is aligned, and the substrate is swung or the tube scattered on the upper surface of the substrate is removed. In a tube alignment jig in which a tube is dropped into the groove and aligned by diffusing it with a palm or the like, a surface of a partition wall that partitions the alignment groove in a longitudinal direction is coaxial with the alignment groove. so,
Since a guide groove with a width smaller than the groove width of the alignment groove was formed in series with the alignment groove, after aligning the tubes,
If the lead wire is moved toward the tube along the guide groove, the lead wire will be inserted into the tube naturally, as in the case of picking the tube by hand and inserting the lead wire there, The tube mounting operation can be performed with good workability without the tube squatting.

At this time, a plurality of projections are provided on the surface of the partition wall in the longitudinal direction of the groove at an interval longer than the length of the tube, and the projections are arranged in every other row of the partition wall in the longitudinal direction of the groove. If the tube is shifted by a predetermined distance in the width direction of the groove, the tube rotates in the horizontal plane by the protrusion, and its length direction follows the groove, so the probability of falling into the groove increases, Quicker alignment.

Further, a cover which is detachable from the substrate and is formed by a side wall surrounding the periphery of the substrate is provided, and the tube is put into a box formed by covering the substrate with the cover. If it is swung, the tube does not jump out of the substrate, and the tube that jumps on the substrate is bounced back on the inner surface of the cover and heads toward the substrate, so the probability of falling into the groove increases, Faster tube alignment.

At this time, ridges running in the depth direction are parallel to the inner surface of the side wall of the cover facing the length direction of the alignment groove along the circumferential direction of the side wall at an interval shorter than the length of the tube. In this case, the probability that the ridges are flipped in various directions toward the base further increases, so that the tubes can be aligned more quickly.
