Referring to (A) and (B) of Fig. 1, the insertion jig 10 of the present embodiment is a tweezers type jig having an elongated pair of plate-like bodies 12a and 12b. The plate-like bodies 12a and 12b are made of stainless steel and have the same shape as each other. In other words, in consideration of the operability and gripability of the finger, the center of the longitudinal direction of the plate-like bodies 12a and 12b is wide, and the length of the plug 20 (described later in detail) shown in FIG. 4 is considered. One end is set to a narrow width. The plate-like bodies 12a and 12b having the above-described shape are joined to each other in the longitudinal direction and the other end side in a posture in which the respective one main faces face each other.

Therefore, one main surface of the plate-like bodies 12a and 12b is the inner side surface of the die, and the other main surface of the plate-like bodies 12a and 12b is the outer side surface of the die, and the one side of the longitudinal direction of the plate-like bodies 12a and 12b The ministry is the front end of the dice. Further, since the plate-like members 12a and 12b are made of stainless steel, the spring characteristics are exhibited in the direction in which the tweezers face away from each other when pressing the outer side faces.

In addition, as shown in FIG. 1(B), the plate-like bodies 12a and 12b are slightly curved inward in the longitudinal direction to the inner side so that the inner side surfaces of the front end portions face each other without applying an external force.

Hereinafter, for convenience of explanation, the longitudinal direction of the plate-like bodies 12a and 12b is designated as the X-axis, the width direction of the plate-like bodies 12a and 12b is designated as the Y-axis, and the thickness along the plate-like bodies 12a and 12b will be specified. The direction is specified as the Z axis. Thus, the inner side surface of the front end portion of the plate-like body 12a faces the negative side of the Z-axis, and on the other hand, the inner side of the front end portion of the plate-like body 12b. The face faces the positive side of the Z axis.

Further referring to FIG. 2, FIG. 3(A) and FIG. 3(B) after the enlarged front end portion, a groove GRa extending along the Y-axis and a plate-like body 12b at the front end portion are formed on the inner side surface of the plate-like body 12a. The inner side surface is also formed with a groove GRb extending along the Y axis. Among them, the positions of the grooves GRa and GRb coincide with each other in the X-axis direction. Since the inner side faces of the front end portions face each other, the grooves GRa and GRb also face each other.

The groove GRa is formed by the side faces SD1a and SD2a and the bottom face BTa, and the groove GRb is formed by the side faces SD1b and SD2b and the bottom face BTb. The side faces SD1a and SD1b are provided on the front end side, and the side faces SD2a and SD2b are provided on the opposite side of the front end.

Further, in the groove GRa, the bottom surface BTa expands in parallel with the inner side surface and the outer side surface of the plate-like body 12a, and in the groove GRb, the bottom surface BTb also expands in parallel with the inner side surface and the outer side surface of the plate-like body 12b.

The cross-sectional shape of each of the grooves GRa and GRb is substantially V-shaped, that is, the side surface SD1a faces the positive side of the X-axis and is slightly inclined toward the negative side of the Z-axis to have an angle with respect to the Z-axis. Further, the side surface SD2a faces the negative side of the X-axis and is slightly inclined toward the negative side of the Z-axis to have an angle with respect to the Z-axis. The side surface SD1b faces the positive side of the X-axis and is slightly inclined toward the positive side of the Z-axis so as to have an angle with respect to the Z-axis. Further, the side surface SD2b faces the negative side of the X-axis and is slightly inclined toward the positive side of the Z-axis so as to have an angle with respect to the Z-axis. As a result, the width of the groove GRa decreases as the groove GRa becomes deeper, and the width of the groove Grb also decreases as the groove GRb becomes deeper.

In addition, the front end surface of the plate-like body 12a (= the surface on the negative side of the X-axis) is defined as "FTa", and the front end surface of the plate-shaped body 12b (= the surface on the negative side of the X-axis) is defined as "FTb", further, the wall portion formed by the front end surface FTa and the side surface SD1a is defined as "WLa", The wall portion formed by the front end face FTb and the side face SD1b is defined as "WLb".

The inner side surface of a part of the inner side surface of the plate-like body 12a which forms the wall part WLa is the side of the negative direction of the Z-axis, and is inclined toward the positive side of the X-axis. In other words, the inner side surface forming a part of the wall portion WLa forms a tapered surface, and the height of the wall portion WLa is lowered from the front end surface FTa toward the side surface SD1a by a predetermined inclination. Further, the inner side surface of a part of the inner side surface of the plate-like body 12b which forms the wall portion WLb faces the positive side of the Z-axis, and is slightly inclined toward the positive side of the X-axis. In other words, the inner side surface forming a part of the wall portion WLb also forms a tapered surface, and the height of the wall portion WLb also decreases from the front end surface FTb toward the side surface SD1b by a predetermined inclination.

A notch NTa is formed in the wall portion WLa, and a notch NTb is formed in the wall portion WLb. Each of the notches NTa and NTb has a curved surface which is curved along the outer peripheral surface of the cylindrical body 26 provided in the plug 20 shown in Fig. 4 . However, the curvature of the curved surface forming the notch NTa increases as it approaches the groove GRa, and the curvature of the curved surface forming the notch NTb also increases as it approaches the groove GRb.

That is, the curvature of the notch NTa coincides with the curvature of the cylindrical body 26 at the position where it is connected to the front end surface FTa, and is lower than the curvature of the cylindrical body 26 at the position connected to the side surface SD1a. Similarly, the curvature of the notch NTb coincides with the curvature of the cylindrical body 26 at a position where it is connected to the front end surface FTb, and is lower than the curvature of the cylindrical body 26 at a position where it is connected to the side surface SD1b. As a result, the depth of the notch NTa gradually increases from the front end surface FTa toward the side surface SD1a as the opening position, and the depth of the notch NTb gradually increases from the front end surface FTb to the side surface SD1b as the opening position.

Referring to FIGS. 4 and 5(A) and (B), and FIG. 6(A) and (B), the plug 20 is formed of a coaxial cable 22 and a connector 24 provided at the tip end of the coaxial cable. Further, the connector 24 is formed by a cylindrical body 26 and a cover 28 which extend in the insertion and removal direction, wherein the cover 28 covers one end of the cylindrical body 26 and the front end of the coaxial cable 22. In addition, the conductor 30 is in the cylindrical body 26 The other side of the end is exposed.

In consideration of the uniformity between the XYZ axes specified for the insertion jig 10, the pin 20 is designated as the X-axis along the length direction of the cylindrical body 26, and is designated as the Y-axis along the length direction of the coaxial cable 22, and is coaxial. The width direction of the cable 22 is designated as the Z axis.

At this time, a part of the cover 28 protrudes toward the positive side of the Z-axis, and the other part of the cover 28 protrudes toward the negative side of the Z-axis. Further, the front end of each of the protruding portions is curved toward the negative side of the X-axis. Hereinafter, the protrusion including the positive side of the portion from the curved portion to the front end is defined as "flange 28a", and the protrusion including the negative side of the portion from the curved portion to the front end is defined as "flange 28b".

As shown in (A) and (B) of FIG. 6, when the connector 24 is viewed from the X-axis direction, at least a part of the outline of the flange 28a depicts a straight line La extending along the Y-axis, and the outline of the flange 28b At least a portion depicts a line Lb extending along the Y-axis. The two straight lines La and Lb have the same length and overlap each other when viewed in the Z-axis direction. Further, the distance from the curved portion to the front end in the X-axis direction coincides between the flanges 28a and 28b. Further, the distance substantially coincides with the respective widths of the bottom faces BTa and BTb forming the grooves GRa and GRb described above.

Further, the distance from the lower surface (=surface on the negative side in the X-axis direction) of the flanges 28a and 28b to the other end side of the cylindrical body 26 is set to "X2" (refer to FIG. 5(B)). The maximum distance from the side surface SD1a or SD1b provided on the insertion jig 10 to the front end surface FTa or FTb is "X1" (see FIG. 3(A)), and the distance X1 is made shorter than the distance X2.

The plug 20 is inserted and removed with respect to the socket 40 by the insertion and removal jig 10 and by the methods shown in Figs. 7(A) and (B), and Figs. 8(A) and (B). Further, the socket 40 is attached to a substrate (not shown).

At the time of insertion, first, the connector 24 forming the plug 20 is disposed above the socket 40 as shown in FIG. 7(A). At this time, the shaft of the cylindrical body 26 provided in the plug 20 overlaps with the shaft of the cylindrical body 42 provided in the socket 40, and the conductor 30 provided in the socket 20 faces the conductor 44 provided in the socket 40, The relative position of the latch 20 and the socket 40 is determined.

Further, the insertion jig 10 is disposed above the connector 24 such that the pair of front ends sandwich the connector 24. At this time, the XYZ axes designated for the insertion jig 10 coincide with the XYZ axes designated for the plug 20, and the grooves GRa and GRb provided in the insertion jig 10 oppose the flanges 28a and 28b provided on the plug 20.

Next, an external force is applied to the outer side surfaces of the plate-like bodies 12a and 12b forming the insertion jig 10. Thereby, as shown in FIG. 7(B), the grooves GRa and GRb are engaged with the flanges 28a and 28b, and the notches NTa and NTb are engaged with the cylindrical body 26, respectively.

At this time, the bottom surface BTa of the groove GRa is in contact with the end surface on which the flange 28a is formed and faces the Z-axis positive direction side, and the bottom surface BTb of the groove GRb is formed to abut against the end surface on the side opposite to the Z-axis in the flange 28b. Further, the curved faces forming the notches NTa and NTb, respectively, abut against the outer peripheral surface portion of the cylindrical body 26. Since the distance X1 shown in FIG. 3(A) is shorter than the distance X2 shown in FIG. 5(B), the front end faces FTa and FTb stay in the positive X-axis direction from the other end side of the cylindrical body 26. Side position.

When the insertion jig 10 is lowered in this state, the cylindrical body 26 forming the plug 20 is fitted into the cylindrical body 42 forming the socket 40 (see FIG. 8(A)), whereby the plug 20 side The conductor 30 is electrically connected to the conductor 44 on the side of the socket 40. Thereby, the plug 20 is assembled to the socket 40. When the assembly is completed, the external force acting on the outer side surfaces of the plate-like bodies 12a and 12b forming the insertion jig 10 is released (see FIG. 8(B)). Thereby, the operation of inserting the plug 20 into the socket 40 carry out. In addition, the operation of unplugging the latch 20 from the socket 40 is performed in the reverse of the above.

As apparent from the above description, the plug 20 has a cylindrical body 26 extending in the X-axis direction, and has flange portions 28a and 28b which are drawn parallel to each other at least a part of the outline viewed from the X-axis direction. The two straight lines La and Lb extending in the ground protrude toward the outside of the cylindrical body 26. The forceps type insertion jig 10 is a jig for inserting and removing the above-described plug 20 with respect to the socket 40. Grooves GRa and GRb that engage with the flanges 28a and 28b at positions corresponding to the two straight lines are formed on the inner side surfaces of the pair of front ends, and notches NTa and NTb that are engaged with the cylindrical body 26 are formed.

By forming the grooves GRa and GRb, the relative position of the insertion jig 10 in the circumferential direction of the cylindrical body 26 can be determined. Further, by forming the notches NTa and NTb, it is possible to determine the relative position of the insertion and removal jig 10 in the longitudinal direction of the straight lines La and Lb forming the contours of the flanges 28a and 28b. Thereby, the plug pin 20 can be reliably held, and the plug pin 20 can be easily inserted and removed with respect to the socket 40.

Further, since the respective cross-sectional shapes of the grooves GRa and GRb are substantially V-shaped, when the pin 20 is held by the insertion jig 10, the flange 28a can be easily guided to the bottom surface BTa of the groove GRa and the bottom surface BTb of the groove GRb. And 28b. Further, the inner side surface of the wall portion WLa is formed as a tapered surface that is slightly inclined toward the positive side in the X-axis direction, and the inner surface of the wall portion WLb is also directed toward the positive side of the Z-axis and slightly in the positive direction of the X-axis. Since the tapered surface is inclined at the side, even when the plugs 20 are clamped, the wall portions WLa and WLb are erroneously brought into contact with the flanges 28a and 28b, and the flanges 28a and 28b can be easily guided to the grooves GRa and GRb.

Further, in the present embodiment, the respective cross sections of the grooves GRa and GRb are formed in a substantially V shape, and the inner side surface forming the wall portion WLa is directed toward the Z-axis negative direction side and slightly toward the X-axis direction. A tapered surface that is inclined to the side. Further, the inner side surface of the wall portion WLb is formed as a tapered surface that is inclined toward the positive side in the Z-axis direction and slightly inclined toward the positive X-axis side. However, as shown in FIG. 9(A), the respective cross sections of the grooves GRa and GRb can be formed into a substantially U shape, and as shown in FIG. 9(B), the respective wall portions WLa and WLb can be formed. The inner side intersects the Z axis perpendicularly.

Further, in the present embodiment, the plate-like members 12a and 12b are made of stainless steel, but the plate-like bodies 12a and 12b may be made of a copper alloy. Further, the material of the front end portion may be ceramic or resin or the like for the tweezers which can replace the structure of the front end portion.
