  Referring to FIGS. 1A and 1B, an insertion / extraction jig 10 of this embodiment is a tweezers-type jig, and has a pair of elongated plates 12a and 12b. The plate-like bodies 12a and 12b are made of stainless steel and have the same shape. In other words, the plate-like bodies 12a and 12b are widened in the center in the length direction in consideration of operability or gripping ability with fingers, and long in consideration of the size of the plug 20 shown in FIG. 4 (details will be described later). The width is narrow at one end in the vertical direction. The plate-like bodies 12a and 12b having such a shape are coupled to each other on the other end side in the length direction with the respective principal surfaces facing each other.

  Therefore, one main surface of the plate-like bodies 12a and 12b is the inner side surface of the tweezers, the other main surface of the plate-like bodies 12a and 12b is the outer side surface of the tweezers, and one end in the length direction of the plate-like bodies 12a and 12b is It becomes the tip of tweezers. In addition, since the plate-like bodies 12a and 12b are made of stainless steel, the tweezers exhibit a spring property in a direction away from each other when the respective outer surfaces are pressed.

  As can be seen from FIG. 1 (B), the plate-like bodies 12a and 12b are bent slightly inward at the approximate center in the length direction so that the inner surfaces of the tip portions face each other in a state where no external force is applied. To do.

  Below, for convenience of explanation, an X axis is assigned along the length direction of the plate-like bodies 12a and 12b, a Y-axis is assigned along the width direction of the plate-like bodies 12a and 12b, and the plate-like bodies 12a and 12b Z axis is assigned along the thickness direction. Then, the inner surface of the tip portion of the plate-like body 12a faces the negative side in the Z-axis direction, while the inner surface of the tip portion of the plate-like body 12b faces the positive side in the Z-axis direction.

  With further reference to FIGS. 2, 3A and 3B in which the tip portion is enlarged, a groove GRa extending along the Y axis is formed on the inner surface of the plate-like body 12a, and the plate at the tip portion is formed. A groove GRb extending along the Y axis is also formed on the inner surface of the body 12b. Here, the positions of the grooves GRa and GRb coincide with each other in the X-axis direction. Since the inner surface of the tip portion faces each other, the grooves GRa and GRb also face each other.

  Groove GRa is formed by side surfaces SD1a and SD2a and bottom surface BTa, and groove GRb is formed by side surfaces SD1b and SD2b and bottom surface BTb. The side surfaces SD1a and SD1b are provided on the tip side, and the side surfaces SD2a and SD2b are provided on the side opposite to the tip.

  Further, in both of the grooves GRa and GRb, the bottom surface BTa extends in parallel to the inner surface and the outer surface of the plate-like body 12a, and the bottom surface BTb also extends in parallel to the inner surface and the outer surface of the plate-like body 12b. .

  However, the cross-sectional shapes of the grooves GRa and GRb are substantially V-shaped. That is, the side surface SD1a is slightly inclined to the negative side in the Z-axis direction while facing the positive side in the X-axis direction, and has an angle with the Z-axis. Further, the side surface SD2a is slightly inclined toward the negative side in the Z-axis direction while facing the negative side in the X-axis direction, and has an angle with the Z-axis. The side surface SD1b is slightly inclined to the positive side in the Z-axis direction while facing the positive side in the X-axis direction, and has an angle with the Z-axis. The side surface SD2b is slightly inclined to the positive side in the Z-axis direction while facing the negative side in the X-axis direction, and has an angle with the Z-axis. As a result, the width of the groove GRa is reduced as the groove GRa is deepened, and the width of the groove GRa is also reduced as the groove GRb is deepened.

  In the following, the tip surface of the plate-like body 12a (= surface facing the negative side in the X-axis direction) is defined as “FTa”, and the tip surface of the plate-like body 12b (= surface facing the negative side in the X-axis direction). ) Is defined as “FTb”. Further, a wall portion formed by the front end surface FTa and the side surface SD1a is defined as “WLa”, and a wall portion formed by the front end surface FTb and the side surface SD1b is defined as “WLb”.

  Of the inner surface of the plate-like body 12a, a part of the inner surface forming the wall portion WLa is slightly inclined to the positive side in the X-axis direction while facing the negative side in the Z-axis direction. That is, a part of the inner surface forming the wall portion WLa has a tapered surface, and the height of the wall portion WLa decreases with a predetermined inclination from the front end surface FTa toward the side surface SD1a. In addition, a part of the inner surface of the plate-like body 12b that forms the wall portion WLb is slightly inclined toward the positive side in the X-axis direction while facing the positive side in the Z-axis direction. That is, a part of the inner surface forming the wall portion WLb also has a tapered surface, and the height of the wall portion WLb also decreases with a predetermined inclination from the front end surface FTb toward the side surface SD1b.

  Cutout NTa is formed in wall portion WLa, and cutout NTb is formed in wall portion WLb. Each of notches NTa and NTb has a curved surface that curves along the outer peripheral surface of cylindrical body 26 provided in plug 20 shown in FIG. However, the curvature of the curved surface forming notch NTa increases as it approaches groove GRa, and the curvature of the curved surface forming notch NTb also increases as it approaches groove GRb.

  That is, the curvature of the notch NTa coincides with the curvature of the cylindrical body 26 at a position in contact with the front end surface FTa, and is lower than the curvature of the cylindrical body 26 at a position in contact with the side surface SD1a. Similarly, the curvature of notch NTb coincides with the curvature of cylindrical body 26 at a position in contact with tip surface FTb, and is lower than the curvature of cylindrical body 26 at a position in contact with side surface SD1b. As a result, the depth of the notch NTa increases as the notch position moves from the front end surface FTa toward the side surface SD1a, and the depth of the notch NTb also increases as the notch position moves from the front end surface FTb toward the side surface SD1b.

  Referring to FIGS. 4, 5A, 5B, 6A, and 6B, plug 20 is formed by coaxial cable 22 and connector 24 provided at the tip thereof. Is done. The connector 24 is formed by a cylindrical body 26 that extends in the insertion / extraction direction, and a cover 28 that covers one end of the cylindrical body 26 and the distal end of the coaxial cable 22. The conductor 30 is exposed at the other end of the cylindrical body 26.

  In consideration of the consistency with the XYZ axes assigned to the insertion / extraction jig 10, the X axis is assigned along the length direction of the cylindrical body 26 in the plug 20, and Y along the length direction of the coaxial cable 22. An axis is assigned, and a Z axis is assigned along the width direction of the coaxial cable 22.

  At this time, a part of the cover 28 protrudes to the positive side in the Z-axis direction, and another part of the cover 28 protrudes to the negative side in the Z-axis direction. Further, the tip of each protrusion is bent to the negative side in the X-axis direction. Hereinafter, the positive protrusion including the portion from the bent portion to the tip is defined as “鍔 28a”, and the negative protrusion including the portion from the bent portion to the tip is defined as “鍔 28b”.

  As shown in FIGS. 6A and 6B, when the connector 24 is viewed from the X-axis direction, at least a part of the outline of the flange 28a draws a straight line La extending along the Y-axis, At least a part of the contour also draws a straight line Lb extending along the Y axis. The two straight lines La and Lb have a common length and overlap each other when viewed from the Z-axis direction. Furthermore, the distance in the X-axis direction from the bent portion to the tip is the same between the flanges 28a and 28b. Further, this distance substantially coincides with the width of each of bottom surfaces BTa and BTb forming grooves GRa and GRb described above.

Further, the distance from the lower surface of each of the flanges 28a and 28b (= the surface facing the negative side in the X-axis direction) to the other end of the cylindrical body 30 is “X2” (see FIG. 5B), and the insertion / extraction jig 10 The maximum distance from the side surface SD1a or SD1b provided on the tip surface to the tip surface FTa or FTb is “X1”.
Then (see FIG. 3A), the distance X1 is shorter than the distance X2.

  The plug 20 is inserted into and removed from the receptacle 40 in the manner shown in FIGS. 7A, 7B, 8A, and 8B using the insertion jig 10. The receptacle 40 is mounted on a substrate (not shown).

At this time, the axis of the cylindrical body 26 provided on the plug 20 overlaps the axis of the cylindrical body 42 provided on the receptacle 40, and the conductor 30 provided on the plug 20 is connected to the conductor 44 provided on the receptacle 40. The relative positions of the plug 20 and the receptacle 40 are determined so as to face each other.

  Further, the insertion / extraction jig 10 is arranged above the connector 24 so that the pair of tips sandwich the connector 24. At this time, the XYZ axes assigned to the insertion / extraction jig 10 are aligned with the XYZ axes assigned to the plug 20, and the grooves GRa and GRb provided on the insertion / extraction jig 10 are provided with flanges 28 a and 28 b provided on the plug 20. Face each other.

  Subsequently, an external force is applied to the outer surfaces of the plate-like bodies 12a and 12b constituting the insertion / extraction jig 10. Accordingly, as shown in FIG. 7B, the grooves GRa and GRb engage with the flanges 28a and 28b, and the notches NTa and NTb engage with the cylindrical body 26, respectively.

  At this time, the bottom surface BTa forming the groove GRa makes contact with the end surface facing the positive side in the Z-axis direction forming a flange 28a, and the bottom surface BTb forming the groove GRb forms an end surface facing the negative side in the Z-axis direction forming the flange 28b. Abut. Further, the curved surfaces forming the notches NTa and NTb partially abut on the outer peripheral surface of the cylindrical body 26. Since the distance X1 shown in FIG. 3A is shorter than the distance X2 shown in FIG.

  When the insertion / extraction jig 10 is lowered in this state, the cylindrical body 26 that forms the plug 20 is fitted to the cylindrical body 42 that forms the receptacle 40 (see FIG. 8A), thereby the conductor on the plug 20 side. 30 is electrically connected to the conductor 44 on the receptacle 40 side. Thus, the plug 20 is attached to the receptacle 40. When the mounting is completed, the external force on the outer surfaces of the plate-like bodies 12a and 12b forming the insertion / extraction jig 10 is released (see FIG. 8B). Thereby, the operation of inserting the plug 20 into the receptacle 40 is completed. In addition, the operation | work which removes the plug 20 from the receptacle 40 is performed in the reverse process to the above-mentioned.

  By forming the grooves GRa and GRb, the relative position of the insertion / extraction jig 10 in the circumferential direction of the cylindrical body 26 is determined. Further, by forming the cutouts NTa and NTb, the relative position of the insertion / extraction jig 10 in the length direction of the straight lines La and Lb forming the contours of the flanges 28a and 28b is determined. As a result, the plug 20 can be securely held, and as a result, the plug 20 can be easily inserted into and removed from the receptacle 40.

  Further, since the cross-sectional shape of each of the grooves GRa and GRb is substantially V-shaped, when the plug 20 is sandwiched by the insertion / extraction jig 10, the flanges 28a and 28b are easily placed on the bottom surface BTa of the groove GRa and the bottom surface BTb of the groove GRb. Can lead to. Furthermore, the inner side surface forming the wall portion WLa forms a tapered surface that faces the negative side in the Z-axis direction and slightly tilts to the positive side in the X-axis direction, and the inner side surface that forms the wall portion WLb is also the positive side in the Z-axis direction.鍔 28a and 28b even when the wall portions WLa and WLb accidentally abut against the flanges 28a and 28b when the plug 20 is sandwiched, because the tapered surface is slightly inclined toward the positive side in the X-axis direction.
