The lower body 10 forms a lower side of the jig to serve to support the upper body 20. And, the lower body 10 forms a lower seating groove portion 12 which is simultaneously open to the upper side and both sides. That is, the lower seating groove 12 is formed above the lower body 10. The lower seating groove 12 serves to seat the shielding line 2 formed inside the wire harness. In particular, the lower seating groove 12 has a lower current sensor 14 therein. The lower current sensor 14 serves to detect the energized state of the shielding wire 2 through which current flows. The lower current sensor 14 is a general detection system sensor that can detect an energized state of a wire when an external power is applied.

In addition, the lower current sensor 14 is embedded and fixed inside the lower seating groove 12, and is fixed by various methods such as bonding.

Here, the lower body 10 can be modified in various shapes and various materials.

In addition, the upper body 20 is formed above the lower body 10 is supported from the lower body (10). And, the upper body 20 forms the upper seating groove 22 on the lower side to face the lower seating groove 12 of the lower body (10). The upper seating groove 22 is simultaneously opened to the lower side and both sides. At this time, both sides of the lower seating groove 12 and both sides of the upper seating groove 22 are the same. In particular, when the upper body 20 is in contact with the lower body 10, the lower seating groove 12 is closed in the up, down direction by the upper seating groove (22). Thus, the upper seating groove 22 serves to prevent the shielding line 2 from escaping to the outside of the upper body 20 and the lower body 10.

In particular, the upper seating groove 22 has an upper current sensor 24 on the inside. The upper current sensor 24 is preferably the same as the lower current sensor 14 formed in the lower seating groove 12. Of course, the current sensors 14 and 24 may be formed only in any one of the lower seating recess 12 and the upper seating recess 22, but the inspection of the energization of the shielding line 2 may be poor. Thus, the lower current sensor 14 and the upper current sensor 24 are preferably formed in the lower seating groove 12 and the upper seating groove 22, respectively.

In addition, the upper current sensor 24 of the upper body 20 is firmly fixed to the upper seating groove 22 by various methods such as bonding. In addition, the upper body 20 can be modified in various shapes and various materials.

This is to prevent the shield wire 2 from being damaged by this gap.

Here, the blocking member 40 includes a blocking plate 42, a side plate 44, and a fastening member 43.

The blocking plate 42 serves to directly prevent a gap generated between the lower current sensor 14 and the upper current sensor 24. Thus, the blocking plate 42 may be formed larger than the size of the gap generated between the lower current sensor 14 and the upper current sensor 24, and may be formed in various shapes.

In addition, the side plate 44 is formed on both sides of the blocking plate 42 is in contact with the side of the lower body 10 or the upper body 20, respectively. Thus, the side plate 44 prevents external exposure of the gap by blocking both sides of the lower current sensor 14, both sides of the lower body 10, both sides of the upper current sensor 24, and both sides of the upper body 20.

At this time, the side plate 44 is preferably in contact with the side of the lower body 10 or the upper body 20. This is to firmly fix the blocking member 40. Thus, the side plate 44 is coupled to the side portion of the lower body 10 or the upper body 20 as a fastening member 43. The coupling member 43 is preferably a mechanical fastening element such as a bolt.

In addition, each of the side plates 44 passes through the long hole 45. In particular, the long hole 45 is formed along the arc trajectory. In addition, the upper body 20 or the lower body 10 connects the guide pin 46 inserted into the long hole 45 to limit the degree of wetting of the upper body 20 with respect to the lower body (10).

As an example, the fastening member 43 is fastened to the side portion of the lower body 10 while being inserted into the side plate 44. Thus, the blocking member 40 is fixed. The guide pin 46 is inserted into the long hole 45. Then, the guide pin 46 is connected to the side portion of the upper body 20, the guide pin 46 is inserted into the long hole (45). At this time, the guide pin 46 is preferably fastened to the upper body (20).

Thus, the guide pin 46 is moved by the moving distance range of the long hole 45.

That is, the long hole 45 serves to limit the amount of opening of the upper body 20 with respect to the lower body 10 by limiting the amount of movement of the guide pin 46.

In addition, the lower body 10 forms a magnetic member 52, the upper body 20 is provided with an attachment member 54 attached to the magnetic member 52 to maintain contact with the lower body 10. It is preferable to.

That is, when the magnetic member 52 does not receive the force to rotate the upper body 20 by the magnetic force of the magnetic member 52 by attaching the attachment member 54 by magnetic force, the upper body 20 and the lower body 10 ) Is firmly fixed.

Of course, if a force greater than the magnetic force of the magnetic member 52 to act to rotate the upper body 20, the upper body 20 and the lower body 10 is opened. At this time, the upper body 20 and the lower body 10 is opened until the guide pin 46 reaches the top or bottom of the long hole (45).

Here, the magnetic member 52 is preferably made of a permanent magnet, the attachment member 54 is preferably formed of a steel material. In addition, the lower body 10 firmly fixes the magnetic member 52 in various ways such as bonding, and the upper body 20 firmly fixes the attachment member 54 in various ways such as bonding.
