Description

  The present invention relates to a jig, and more particularly to a jig for holding a cable inserted toward a predetermined direction.

  As a conventional jig, for example, a guide jig described in Patent Document 1 is known. The guide jig described in Patent Document 1 will be described below with reference to the drawings. FIG. 11 is an external perspective view of the guide jig 500, the electric wires 502a and 502b, and the crimp terminal 504 described in Patent Document 1.

  The crimp terminal 504 is a terminal for electrical connection by holding two electric wires. The guide jig 500 is used when two electric wires are inserted into the crimp terminal 504. More specifically, as shown in FIG. 11, the guide jig 500 is provided with a guide groove 506. The width of the guide groove 506 has a structure that becomes narrower from the entrance to the exit of the electric wires 502a and 502b (that is, as it approaches the crimp terminal 504). Further, the upper side of the guide groove 506 is covered with a lid 508. In the guide jig 500 having the above-described configuration, since the entrance is wider than the exit, the electric wires 502 a and 502 b can be easily inserted into the guide jig 500 and the crimp terminal 504.

  However, the guide jig 500 described in Patent Document 1 has a problem that the electric wires 502a and 502b cannot be easily detached from the guide jig 500, as will be described below. The guide jig 500 is provided with a lid 508. Therefore, the electric wires 502 a and 502 b cannot be removed from the guide jig 500 unless the cover 508 is removed after the crimping terminal 504 is crimped and the electric wires 502 a and 502 b are fixed.

  Below, the jig | tool which concerns on one Embodiment of this invention is demonstrated.

(Configuration of jig)
First, the configuration of a jig according to an embodiment will be described with reference to the drawings. FIG. 1 is an external perspective view of a jig 10 according to an embodiment of the present invention. FIG. 2 is an external perspective view of the jig 10 with the coaxial cable 20 removed. FIG. 3 is an external perspective view of the main body 12 of the jig 10. FIG. 4 is an external perspective view of the auxiliary tool 14 of the jig 10. FIG. 5 is a plan view of the jig 10.

  As shown in FIGS. 1 and 2, the jig 10 holds a coaxial cable 20 that is inserted toward a predetermined direction, and includes a main body 12 and an auxiliary tool 14. Hereinafter, a predetermined direction in which the coaxial cable 20 is inserted is defined as an x-axis direction, a vertical direction is defined as a z-axis direction, and a direction orthogonal to the x-axis direction and the z-axis direction is defined as a y-axis direction.

  The main body 12 is a member made of metal or resin, and includes an upper surface S1 and side surfaces S2 to S4 as shown in FIG. The upper surface S1 extends in the x-axis direction and contacts the coaxial cable 20 from the positive direction side in the z-axis direction as shown in FIG. More specifically, the upper surface S1 is a plane that faces the negative direction side in the z-axis direction, and extends in the x-axis direction along the side of the main body 12 on the positive direction side in the y-axis direction. Further, the end on the negative direction side in the x-axis direction of the upper surface S1 is inclined with respect to the xy plane (horizontal plane) so as to go to the positive direction side in the z-axis direction as it goes to the negative direction side in the x-axis direction. ing.

  The side surface S2 extends in the x-axis direction, and comes into contact with the coaxial cable 20 from the negative direction side in the y-axis direction, as shown in FIG. More specifically, the side surface S2 is a plane facing the positive direction side in the y-axis direction, and extends in the x-axis direction in a state orthogonal to the upper surface S1.

  The side surface S3 extends in the x-axis direction so as to face the side surface S2, and comes into contact with the coaxial cable 20 from the positive direction side in the y-axis direction as shown in FIG. More specifically, the side surface S2 is a plane that faces the negative direction side in the y-axis direction, and extends in the x-axis direction in a state orthogonal to the upper surface S1. However, the side surface S3 does not face the entire x-axis direction of the side surface S2, but faces only the vicinity of the end of the side surface S2 on the positive direction side in the x-axis direction. Furthermore, the width of the side surface S3 in the z-axis direction is narrower than the width of the side surface S2 in the z-axis direction. As a result, as shown in FIG. 5, the side surface S2 is exposed in a lower region of the side surface S3 when viewed in plan from the positive direction side in the y-axis direction. The fact that the side surface S2 is exposed will be described later.

  As described above, the upper surface S1 positions the coaxial cable 20 in the z-axis direction by contacting the coaxial cable 20 from the positive direction side in the z-axis direction. Further, the side surfaces S2 and S3 respectively contact the coaxial cable 20 from the negative direction side and the positive direction side in the y-axis direction, thereby positioning the coaxial cable 20 in the y-axis direction. That is, the upper surface S1 and the side surfaces S2, S3 form a space Sp, and the coaxial cable 20 is positioned in the y-axis direction and the z-axis direction by passing through the space Sp.

  The side surface S4 is connected to the end portion on the negative side in the x-axis direction of the side surface S3 so as to face the side surface S2, and as shown in FIG. 3, the side surface S4 approaches the positive side in the x-axis direction. It inclines with respect to side S2 so that the space | interval with S2 may become narrow. More specifically, the side surface S4 is a surface facing the negative direction side in the y-axis direction, and extends in the x-axis direction in a state orthogonal to the upper surface S1. However, the side surface S4 is not parallel to the xz plane, but is inclined with respect to the xz plane so as to go to the negative direction side in the y-axis direction as it goes to the positive direction side in the x-axis direction. Furthermore, the side surface S4 does not face the entire x-axis direction of the side surface S2. Further, the width of the side surface S4 in the z-axis direction is narrower than the width of the side surface S2 in the z-axis direction. As a result, as shown in FIG. 5, the side surface S2 is exposed in the lower region of the side surface S4 when viewed from the positive side in the y-axis direction. The fact that the side surface S2 is exposed will be described later.

  The auxiliary tool 14 is a member made of metal or resin, and is a rectangular parallelepiped member having a longitudinal direction in the x-axis direction as shown in FIG. The auxiliary tool 14 includes an upper surface S5 and a protrusion 14a, and is disposed on the negative side of the upper surface S1 in the z-axis direction, as shown in FIGS.

  The upper surface S5 is a surface on the positive side in the z-axis direction of the rectangular parallelepiped auxiliary tool 14, and faces the upper surface S1.

  The protrusion 14a protrudes from the upper surface S5 to the positive direction side in the z-axis direction. As shown in FIG. 2, the protrusion 14a is inclined with respect to the xy plane (horizontal plane) so as to approach the upper surface S1 as it goes to the positive direction side in the x-axis direction. Further, the end of the projection 14a on the positive direction side in the z-axis direction is located on the negative direction side in the z-axis direction with respect to the upper surface S1, as shown in FIG. The distance between the protrusion 14a and the upper surface S5 is substantially equal to the thickness of the coaxial cable 20. Thereby, as shown in FIG. 5, when the side surface S2 is viewed from the positive side in the y-axis direction, the region on the negative side in the x-axis direction of the side surface S4 (that is, z of the upper surface S5 and the protrusion 14a). (Area on the positive side in the axial direction).

  Here, the side surface S2 will be described in more detail. As described above, the side surface S2 is partially exposed when viewed from the positive side in the y-axis direction. In the present embodiment, as shown in FIG. 5, the side surface S2 is a region on the negative direction side in the x-axis direction from the side surface S4 and z of the side surfaces S3 and S4 when viewed in plan from the positive direction side in the y-axis direction. The region on the negative direction side in the axial direction is exposed so as to include one strip-shaped region E having a width equal to or larger than the width W of the coaxial cable 20. Thereby, the coaxial cable 20 along the region E shown in FIG. 5 can be taken out from the jig 10 to the positive side in the y-axis direction.

(How to use the jig)
Below, the usage method of the jig | tool 10 is demonstrated, referring drawings. The jig 10 is used when the connector 30 shown in FIG. 1 is attached to the coaxial cable 20. 6, FIG. 8, and FIG. 10 are external perspective views of the jig 10, the coaxial cable 20, and the connector 30 when the connector 30 is attached. 7 and 9 are plan views of the jig 10 in the state of FIGS. 1 and 8.

  As shown in FIG. 6, the connector 30 is connected to the connection portion 32. The connector 30 and the connection part 32 are comprised with the metal plate of 1 sheet. Then, the connector 30 is positioned on the positive side of the space Sp in the x-axis direction.

  Next, as shown in FIG. 1, the coaxial cable 20 is inserted into the jig 10 toward the positive side in the x-axis direction. As shown in FIG. 7, when the coaxial cable 20 passes in the vicinity of the protrusion 14a, the coaxial cable 20 is pushed up by the protrusion 14a to the positive side in the z-axis direction and brought into contact with the upper surface S1. Thereby, the coaxial cable 20 is positioned in the z-axis direction. Furthermore, as shown in FIG. 1, when the coaxial cable 20 passes through the vicinity of the side surface S4, the coaxial cable 20 is pushed to the negative side in the y-axis direction by the side surface S4 and brought into contact with the side surface S2. Thereby, the coaxial cable 20 is positioned in the y-axis direction. Thereafter, as shown in FIG. 1, the coaxial cable 20 is inserted into the jig 10 until the tip projects out of the jig 10.

  Next, as shown in FIG. 8, the connector 30 is attached to the coaxial cable 20 using a tool 50. More specifically, the tongue piece 34 of the connector 30 is caulked by pressing the tool from the positive side in the z-axis direction. At this time, the coaxial cable 20 is pushed down to the negative side in the z-axis direction by the tool 50. Thereby, as shown in FIG.8 and FIG.9, the coaxial cable 20 is pulled out from the space Sp. As a result, the coaxial cable 20 extends along the region E (see FIG. 5) when viewed from the positive side in the y-axis direction.

  Next, as shown in FIG. 10, the connection part 32 is slid to the positive direction side in the y-axis direction. Thereby, the coaxial cable 20 is taken out from the jig 10. Then, the connector 30 next to the connector 30 to which the coaxial cable 20 is connected is set on the positive direction side in the x-axis direction of the space Sp of the jig 10.

(effect)
According to the jig 10 as described above, as shown in FIG. 5, the side surface S <b> 2 is a region on the negative direction side in the x-axis direction from the side surface S <b> 4 when viewed in plan from the positive direction side in the y-axis direction. The region on the negative side in the z-axis direction of the side surfaces S3 and S4 is exposed so as to include a single band-shaped region E having a width equal to or greater than the width W of the coaxial cable 20. Therefore, as shown in FIG. 8 and FIG. 9, the coaxial cable 20 can be taken out from the jig 10 to the positive direction side in the y-axis direction by fitting the connector 30 along the region E by attaching the connector 30. Is possible. That is, the coaxial cable 20 can be removed from the jig 10 without performing a process such as attaching and detaching the lid.

  Further, in the jig 10, the end portion on the negative direction side in the x-axis direction of the upper surface S <b> 1 is directed toward the positive direction side in the z-axis direction toward the negative direction side in the x-axis direction with respect to the xy plane. Inclined. Therefore, when the coaxial cable 20 is inserted into the jig 10, the coaxial cable 20 is guided into the jig 10 by the upper surface S <b> 1 even if it is slightly shifted to the positive direction side in the z-axis direction. Therefore, the coaxial cable 20 can be easily inserted into the jig.

  The protrusion 14a protrudes from the upper surface S5 to the positive direction side in the z-axis direction. As shown in FIG. 2, the protrusion 14a is inclined with respect to the xy plane so as to approach the upper surface S1 in the x-axis direction. Thereby, when the coaxial cable 20 is inserted into the jig 10, the coaxial cable 20 is suppressed from being caught by the protrusion 14a. Therefore, the coaxial cable 20 can be easily inserted into the jig.

  As described above, the present invention is useful for jigs, and is particularly excellent in that a cable can be easily detached.
