Description

  The present invention relates to a relay connector used for electrically connecting a connector to be inspected disposed on a substrate to be inspected such as an electronic component to a measuring instrument or the like for inspection.

  In a small electronic device such as a mobile phone or a digital camera, in order to mount a large number of electronic circuits in a small space, a plurality of substrates are arranged so as to overlap each other. Some are electrically connected via a provided connector. Therefore, in order to inspect the board and the connector disposed thereon, a measuring instrument or the like may be appropriately electrically connected to the connector. Here, in order to inspect the entire board to be inspected and the connector to be inspected, it is desirable to fit the connector on the jig side to be a pair to the connector to be inspected and to electrically connect to the measuring instrument. However, the number of endurance times for fitting and pulling out is about 50, which is relatively small, regardless of whether the connector is to be inspected or the jig side. Therefore, the jig-side connector must be replaced every time the number of inspections reaches the endurance number. If this jig-side connector is fixed to the jig-side board by soldering and a large number of wiring cables connected to the measuring instrument etc. are soldered to the jig-side board, only the jig-side connector will be Cannot be easily replaced. Therefore, the entire jig-side connector, jig-side substrate, and wiring cable must be replaced. Then, the malfunction that the cost of a measurement inspection becomes large arises.

Therefore, the applicant of the present invention has already proposed a technique as disclosed in Japanese Patent Application Laid-Open No. 2004-273192, and has reduced the cost of measurement and inspection by reducing the number of parts to be replaced. In the previously proposed technique, a jig-side connector that is paired with a connector to be inspected is disposed on an insulating relay substrate, and this insulating relay substrate is detachably disposed on a probe unit made of an insulating material. The probe unit is provided with a probe. And the terminal of a jig side connector is electrically connected to the terminal provided in the insulation relay board | substrate, and the probe of a probe unit contact | abuts and is electrically connected to the terminal of this insulation relay board | substrate. The other end of the probe provided in the probe unit is appropriately electrically connected to a number of wiring cables connected to a measuring instrument or the like. Therefore, the connector to be inspected is electrically connected to a measuring instrument or the like via the jig side connector, the insulating relay substrate, the probe, and the wiring cable. Therefore, when the number of times of inspection and use of the jig-side connector reaches the endurance number, the jig-side connector and the insulating relay substrate may be replaced, and the cost of measurement and inspection can be reduced by the amount of replacement.
JP 2004-273192 A

  In the technique proposed in the above-mentioned Japanese Patent Application Laid-Open No. 2004-273192, only the jig-side connector and the insulating relay board need be replaced, and the cost of measurement and inspection can be reduced as compared with the prior art. It is not satisfactory. Therefore, the inventors make the probe directly contact the terminal of the connector to be inspected, and it is not necessary to replace the jig-side connector and the insulating relay board, and if the contacted probe is damaged, only the probe is replaced. We thought that the cost of measurement and inspection could be further reduced by adopting such a structure.

  The present invention has been made based on such a concept, and an object thereof is to provide a relay connector in which a probe is brought into contact with a connector to be inspected.

  In order to achieve such an object, the relay connector of the present invention is a relay connector for bringing a probe into contact with a terminal of a connector to be inspected disposed on a substrate to be inspected and electrically connecting it to a measuring instrument.

  Then, the pressing operation member is provided with an engagement protrusion and the floating guide is provided with an engagement receiving portion, and the engagement protrusion is engaged with the engagement receiving portion in the open state of the pressing operation member, and the floating operation is performed. You may comprise so that a guide may control that it moves to the said pin block side.

  Further, the pressing operation member is brought into the opening state and the pressing state by a swing shaft disposed on a surface parallel to a surface facing the pin block side of the connector to be inspected and fitted into the guide hole. In addition to being disposed so as to be able to swing, a pressing block can be swingably disposed on a distal end side that presses the connector to be inspected with a second swinging shaft parallel to the swinging shaft. .

  Further, a floating pin having enormous portions at both ends is disposed through the floating guide and the pin block in the approaching and separating direction of the floating guide, and the floating guide is separated from the pin block by the enlarging portions at both ends. It is also possible to restrict the distance that can be moved, and to loosely fit a float spring to the floating pin and to contract between the floating guide and the pin block.

  In addition, the distance that the floating pin can move in the separation direction is adjusted by an adjustment screw that is screwed to one end thereof, and an adjustment hole is formed in the pressing operation member facing the adjustment screw, It is also possible to configure so that the adjustment screw can be adjusted from the outside.

  Further, a plane that is larger than the board to be inspected is formed on the board mounting surface of the floating guide for fitting and inserting the board to be inspected into the guide hole toward the pin block side. You may comprise so that the position of the to-be-inspected board | substrate is not regulated at all in the state which fitted and inserted the inspection side connector in the said guide hole.

  Still further, a restricting portion for restricting the swingable pressing operation member to the opening state side is provided, and the engaging protrusion is in the state where the pressing operation member is restricted by the restricting portion. You may comprise so that it may engage with an engagement receiving part.

  The relay connector according to the present invention is a relay connector for bringing a probe into contact with a terminal of a connector to be inspected disposed on a substrate to be inspected and electrically connecting it to a measuring instrument, and is a base made of an insulating material. A floating guide made of an insulating material is disposed in contact with and separated from the member, and the inspected-side connector is fitted to the floating guide with the inspected substrate inserted between the base member and the floating guide. A guide hole is formed for insertion and positioning, and a pressing operation member is disposed so that the floating guide side can be approached and separated while the floating guide is sandwiched between the base member, and the floating operation is provided in the pressing operation member. A pin block made of an insulating material is arranged facing the guide, and the pin block is placed on the floating guide. The pressing operation in the direction of separating the pin block from the floating guide by arranging a probe on the pin block so as to contact the terminal of the connector to be inspected fitted and inserted into the guide hole in a contact state The floating guide is separated from the base member in conjunction with the operation of the member, and an open state allowing insertion of the substrate to be inspected between the base member and the floating guide and the guide hole of the floating guide You may comprise so that the said press operation member may be operated to the press state which pressed the said pin block to the said to-be-tested side connector side inserted by fitting.

  Then, facing the guide hole of the floating guide, the substrate mounting surface provided on the base member is provided with a substrate positioning recess having a shape of a tip portion on the insertion side of the substrate to be inspected from the edge, The substrate positioning recess may be used to position the substrate to be inspected by restricting the insertion size and lateral displacement of the substrate to be inspected.

  The floating guide may be guided by a linear guide provided on the base member so as to abut and separate in a vertical direction with respect to the substrate mounting surface of the base member.

  Further, the pressing operation member is swingably disposed so that the floating guide side approaches and separates from the base member, and is elastically biased in a direction in which the floating guide side of the pressing operation member approaches. A pressing spring may be contracted between the pressing operation member and the base member.

  In addition, the pressing operation member is swingably disposed so that the floating guide side approaches and separates from the base member, and the lever member is parallel to the swing shaft of the pressing operation member with respect to the base member. The lever member is arranged so as to be swingable, and one end portion of the lever member is engaged with the floating guide, and the other end portion is pressed by the operation of the pressing operation member. As the floating guide side swings in the separation direction from the base member, the floating guide may swing in the separation direction from the base member to be in the open state.

  Furthermore, the depth of the guide hole drilled in the floating guide can be configured to coincide with the height of the connector to be inspected.

  Further, a concave portion is provided on the surface of the floating guide on the pin block side, and a convex portion that fits into the concave portion is formed on the surface of the pin block on the floating guide side. Accordingly, the floating guide and the pin block can be relatively positioned.

  Furthermore, the tip outer side portion of the pressing operation member on the floating guide side can be formed as a chamfered oblique surface.

  In the relay connector according to claim 1, the inspected connector faces the pin block side toward the guide hole of the floating guide that is elastically biased and separated from the pin block in the open state of the pressing operation member. In this state, the floating guide and the connector to be inspected are pressed to the pin block side, and the connector to be inspected is inserted into the guide hole. When positioning, the connector to be inspected does not come into contact with the probe in an inappropriate posture, and a force that relatively shifts laterally when the connector to be inspected contacts the probe acts. And the probe or the connector to be inspected is not damaged.

  In the relay connector according to claim 2, the pressing operation member is provided with the engagement protrusion and the floating guide is provided with the engagement receiving portion, and the engagement protrusion and the engagement receiving portion are provided in the open state of the pressing operation member. Since the floating guide is restricted from moving to the pin block side by engaging, the force toward the pin block side to the floating guide when the connector to be inspected is fitted and inserted into the guide hole of the floating guide. The floating guide does not move even if this occurs, the inspected connector that is not properly positioned does not contact the probe, and the probe or the inspected connector is not damaged.

  In the relay connector according to the third aspect of the present invention, since the pressing operation member is swingably disposed between the open state and the pressing state by the swing shaft, the structure for disposing the pressing operation member is simple. In addition, since the pressing block is swingably disposed on the tip end side that presses the connector to be inspected by the second swinging shaft parallel to the swinging shaft, the floating guide is correctly pressed toward the pin block side in the approaching direction. be able to.

  Furthermore, in the relay connector according to the fourth aspect, the distance that the floating guide can move from the pin block in the separating direction is regulated by the floating pins having the enormous portions at both ends. Moreover, the floating guide is elastically biased in the separation direction by the float spring, and the floating guide can be separated from the pin block in the open state of the pressing operation member.

  In the relay connector according to claim 5, the distance that the floating pin can move in the separating direction is adjusted by the adjusting screw that is screwed to one end side thereof. Can be set arbitrarily. Moreover, since the adjustment hole is formed in the pressing operation member facing the adjustment screw, even if the adjustment screw is loosened during use, it can be easily readjusted from the outside.

  Further, in the relay connector according to claim 6, the board mounting surface of the floating guide for fitting and inserting the connector to be inspected into the guide hole toward the pin block side has a larger plane than the board to be inspected. Since the position of the board to be inspected is not restricted in a state where it is formed and the connector to be inspected is fitted and inserted into the guide hole, the connector to be inspected is mounted with the position shifted from the board to be inspected. Even if it is done, a force that shifts the connector to be inspected sideways with respect to the substrate to be inspected does not act from anywhere, and no problem is caused in the inspection.

  Furthermore, in the relay connector according to claim 7, a state is provided in which a restricting portion for restricting the swingable pressing operation member to the open state side is provided, and the pressing operation member is restricted by the restricting portion. Since the engagement protrusion engages with the engagement receiving portion, when the pressing operation member is restricted to the open state, the engagement protrusion engages with the engagement reception portion, and the floating guide is pinned. The movement to the block side is reliably restricted.

  In the relay connector according to claim 8, with the board to be inspected inserted between the base member and the floating guide, the connector to be inspected is fitted and inserted into the guide hole drilled in the floating guide. If the base member is arranged on the lower side, the pin block is brought into contact with the floating guide and the probe is brought into contact with the terminal of the connector to be inspected fitted and inserted into the guide hole. The inspection can be performed in a state where the inspected connector is disposed on the upper side of the inspected substrate.

  In the relay connector according to claim 9, the board positioning concave portion having the shape of the tip portion on the insertion side of the board to be inspected is bordered on the board mounting surface of the base member facing the guide hole of the floating guide. Therefore, the substrate positioning concave portion restricts the insertion dimension and lateral displacement of the substrate to be inspected, and positions the substrate to be inspected. Thus, the inspected connector disposed on the inspected substrate is positioned relative to the guide hole drilled in the floating guide.

  In the relay connector according to claim 10, the floating guide is guided by the linear shaft provided on the base member and abuts and separates in a direction perpendicular to the substrate mounting surface of the base member. When the connector to be inspected is inserted into the guide hole drilled in the floating guide, a force that shifts the connector to be inspected to the side does not act, and the inspected connector is provided. A force that shifts the substrate to the side does not work.

  Furthermore, in the relay connector according to claim 11, the pressing operation member is swingably disposed so that the floating guide side approaches and separates from the base member, and the direction in which the floating guide side of the pressing operation member approaches. Since the pressing spring is contracted between the pressing operation member and the base member so as to be elastically biased, the structure is simple. During the pressing operation of the pressing member, the inspected board is allowed to be inserted, and when the pressing operation is released, the pressing state of pressing the pin block against the inspected connector is measured. It is possible to perform the operation without requiring a pressing operation during the measurement.

  Further, in the relay connector according to claim 12, as the floating guide side of the pressing operation member swings in the separating direction from the base member, the floating guide swings in the separating direction from the base member and opens. Thus, while the pressing operation member is being pressed, the floating guide is separated from the base member, and insertion of the substrate to be inspected is reliably permitted.

  Furthermore, in the relay connector according to claim 13, the depth of the guide hole formed in the floating guide is made to coincide with the height of the connector to be inspected. The surface on the pin block side of the connector to be inspected that is fitted and inserted into the guide hole is in the same plane, and the probe is arranged on the pin block on the basis of this surface, so that It can be elastically contacted with appropriate force.

  Further, in the relay connector according to claim 14, a concave portion is provided on the surface of the floating guide on the pin block side, and a convex portion that fits into the concave portion is formed on the surface of the pin block on the floating guide side, Since the floating guide and the pin block are relatively positioned by the engagement of the concave and convex portions, the probe disposed on the pin block is attached to the inspected connector positioned in the guide hole of the floating guide. The contact can be made at an appropriate position.

  Furthermore, in the relay connector according to claim 15, since the tip outer portion on the floating guide side of the pressing operation member is formed in a chamfered oblique surface, the inspected side connector and the inspected substrate are connected to the inspected substrate. When inspecting the CCD camera elements and the like disposed in close proximity, the pressing operation member of the relay connector of the present invention does not interfere with the inspection.

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a side view of the relay connector according to the first embodiment of the present invention in a pressed state. FIG. 2 is a plan view of FIG.

FIG. 11 is an exploded perspective view of the pressing operation member, the hinge member, and the base member. 12 is a cross-sectional view taken along the line AA in FIG. FIG. 13 shows a structure in which the wiring board is pressed against the base member by the rib provided on the hinge member, (a) is a partially cutaway side view, and (b) is a rear view. FIG. 14 is a diagram for explaining the action due to the upper end of the pressing operation member being cut out into a chamfered oblique surface.

  1 to 14, the relay connector according to the first embodiment of the present invention is configured as follows. First, a hinge member 12 is fixed to the base member 10 with a screw 10a, and a pressing operation member 14 is swingably disposed in the hinge member 12 through a swing shaft 16. A pressing spring 18 is contracted between the rear side of the pressing operation member 14 and the hinge member 12. A pressing block 22 is swingably disposed on the distal end side of the pressing operation member 14 by a second swinging shaft 20 penetratingly disposed parallel to the swinging shaft 16. Then, the floating guide 26 made of an insulating material can be linearly approached and separated in a substantially swinging direction on the distal end side of the pressing operation member 14 with respect to the pin block 24 made of an insulating material, and the distance in the separating direction is restricted. Arranged. Further, the wiring board 28 is fixed to the side of the pin block 24 opposite to the floating guide 26 by screws 28a. The wiring board 28 is fixed to the base member 10 side, and the pin block 24 and wiring board 28 are fixed to the base member 10 by screws 24a. Is done. Then, the engagement receiving portion 26f is projected from the floating guide 26, the engagement projection 14a is projected from the pressing operation member 14, and the engagement projection 14a is formed at the engagement receiving portion 26f in the open state of the pressing operation member 14. Formed to engage. Therefore, when the pressing operation member 14 is in the open state, the floating guide 26 is separated from the pin block 24 and is restricted from moving to the pin block 24 side. When the pressing operation member 14 is in the open state, the rear end of the pressing operation member 14 abuts on the hinge member 12 to restrict the swinging, and the contacted portion of the hinge member 12 acts as a restricting portion.

  With respect to the pin block 24, the floating guide 26 is linearly moved in the vertical direction in FIGS. 1 and 3 in accordance with the swing of the pressing operation member 14 between the open state and the pressing state in which the pressing member 14 is closed. It can be moved. Therefore, a linear shaft 30a is planted in the vertical direction on the pin block 24, and a linear cylindrical member 30b inserted in the floating guide 26 so that the linear shaft 30a is slidable in the axial direction is disposed in the vertical direction. The linear movement is realized by the linear guide 30 including the linear shaft 30a and the linear cylindrical member 30b. Further, floating pins 32 having enormous portions at both ends in the vertical direction are provided through the pin block 24 and the floating guide 26. The distance between the enormous portions at both ends can be adjusted by screwing the adjusting screw 32a provided on one end side. Further, a float spring 34 loosely fitted to the floating pin 32 is contracted between the pin block 24 and the floating guide 26 and elastically biased in a direction to separate the floating guide 26 from the pin block 24. Therefore, the distance at which the floating guide 26 can be separated from the pin block 24 is arbitrarily regulated by adjusting the floating pin 32, and the pressing operation member 14 is in the open state by the elastic force of the float spring 34 that is contracted. The floating guide 26 is separated from the pin block 24.

  The floating guide 26 is provided with a board mounting surface 26a on which the board to be inspected 36 is mounted. A connector 38 to be inspected provided on the board to be inspected 36 can be fitted and inserted into the board mounting surface 26a. A guide hole 26b is formed through. The outer peripheral wall of the inspected connector 38 is in contact with the inner peripheral wall of the guide hole 26b so that the inserted inspected connector 38 is positioned. The substrate mounting surface 26a around the guide hole 26b is not provided with any configuration for positioning the mounted substrate to be inspected 36, and has a sufficiently large plane. In addition, a recess 26c is provided on the surface on the pin block 24 side on the back side of the substrate mounting surface 26a with the guide hole 26b formed through the hole being substantially at the center. The thickness of the bottom surface of the recess 26c and the substrate mounting surface 26a, that is, the depth of the guide hole 26b is formed by adjusting the substrate mounting surface 26a by cutting or the like so as to coincide with the height of the connector 38 to be inspected. Reinforcing ribs 26d for increasing the mechanical strength are provided on the back sides of both ends of the substrate mounting surface 26a.

  In the pin block 24, a lower pin block 40 and an upper pin block 42 are integrated by a screw 42b, a convex portion 42a is provided on the upper pin block 42, and is fitted into a concave portion 26c of the floating guide 26. The pin block 24 and the floating guide 26 are configured to be relatively positioned. Further, a large number of probe holes 46 are formed in a row so as to penetrate the lower pin block 40 and the upper pin block 42 in the vertical direction. And the insertion hole 50 which penetrates the lower pin block 40 and the upper pin block 42 to the up-down direction and in which the position adjustment block 48 which consists of an insulating material is inserted is drilled. The position adjustment block 48 is also composed of a lower position adjustment block 48a and an upper position adjustment block 48b, which are appropriately integrated, and a plurality of probe holes 52 are perforated in the vertical direction. The position adjustment block 48 is adjusted so that the position of the probe hole 52 is adjusted within the insertion hole 50 so that the distance between the lower pin block 40 and the probe hole 46 formed in the upper pin block 42 is appropriate. The pin 56 is fixed. In the insertion hole 50, the position adjustment block 48 can be moved only in the direction for adjusting the distance between the probe holes 46 and 52, and cannot be moved in the direction orthogonal thereto. . The probe holes 46 and 52 are provided with a narrowed portion at the upper end so that the probe 54 can be appropriately inserted from the lower side and does not come out upward. Of course, the pitch in which the probe holes 46 and 52 are drilled is matched with the pitch P of the terminals 38a of the connector to be inspected 38 shown in FIG. Further, the distances between the probe holes 52 of the position adjustment block 48, the lower pin block 40, and the probe holes 46 of the upper pin block 42 correspond to the distance d between the two rows of the terminals 38a of the connector 38 to be inspected. Of course, it is adjusted appropriately. Moreover, an appropriate number of probes 54 are inserted into the probe holes 46 and 52 from the lower side at appropriate positions according to the terminals 38a of the connector 38 to be inspected.

  The wiring board 28 is disposed from the lower side with respect to the pin block 24 in which the probe 54 is inserted into the probe holes 46 and 52, and is fixed and integrated by screws 28a from the lower side. By fixing the wiring board 28, the probe 54 does not come out of the probe holes 46 and 52. Then, the pin block 24 to which the wiring board 28 is fixed is fixed to the base member 10 with screws 24a from above. Note that the base member 10 may be appropriately fixed to an inspection jig or the like (not shown) with a fixing screw 10b in advance. Therefore, as shown in FIG. 9, the plunger of the probe 54 inserted into the probe holes 46 and 52 can be brought into contact with the terminal 38 a of the inspected connector 38 shown in FIG. 8. As shown in FIG. 10, the terminal pattern 28 b provided on the wiring board 28 is formed long in the moving direction so that the plunger of the probe 54 can contact even if the position adjusting block 48 moves.

  Further, the swing operation of the pressing operation member 14 that is swingably disposed on the hinge member 12 is restricted by the hinge member 12 from being moved in the swing direction. The engagement protrusion 14a and the engagement receiving portion 26f are formed so as to engage with each other in a state where the movement in the swinging direction to be in the open state is restricted. The hinge member 12 is provided with ribs 12a as shown in FIG. 13 and acts to press the wiring board 28 against the base member 10 from above, thereby restricting the wiring board 28 from being lifted from the base member 10. Yes.

  The pressing operation member 14 is provided with a hole 14c and an adjustment hole 14d so as to face the linear guide 30 and the floating pin 32, respectively. The floating guide 26 has a hole 26e facing the screw 24a that fixes the pin block 24 to which the wiring board 28 is fixed to the base member 10. Further, the upper end of the pressing operation member 14 is formed as a chamfered oblique surface 14b. The external dimensions of the first embodiment of the relay connector of the present invention are 27 mm in height, 26 mm in width and 60 mm in length, and can be held by hand for inspection work.

  In such a configuration, the pressing operation member 14 is oscillated against the elasticity of the pressing spring 18 to be in an open state, the substrate to be inspected 36 is disposed on the substrate mounting surface 26a of the floating guide 26, and the connector to be inspected is provided. 38 is fitted and inserted into the guide hole 26b. The connector 38 to be inspected is positioned by fitting and inserting into the guide hole 26b. Here, no positioning force is applied to the inspected board 36 itself, and no force is applied to the inspected board 36 to shift the position of the inspected side connector 38 to the side. While the pressing operation member 14 is maintained in the open state, the engagement protrusion 14 a of the pressing operation member 14 is engaged with the engagement receiving portion 26 f of the floating guide 26, and the floating guide 26 is moved from the pin block 24. It is in a separated state and does not move inadvertently to the pin block 24 side. Accordingly, the floating guide 26 is erroneously moved downward during the operation of fitting and inserting the connector to be inspected 38 into the guide hole 26b, and the probe 54 is moved with respect to the connector 38 to be inspected in an inappropriate posture. There is no possibility that either the inspected connector 38 or the probe 54 will be damaged by contact. Then, when the pressing operation member 14 is closed and pressed by the elasticity of the pressing spring 18, the floating guide 26 is linearly moved to the pin block 24 side by the linear guide 30, and the terminal 38 a of the connector 38 to be inspected. The plunger of the probe 54 comes into contact with the above. At this time, the concave portion 26c of the floating guide 26 and the convex portion 42a of the pin block 24 are fitted, so that the floating guide 26 and the pin block 24 are reliably aligned relative to each other. Accordingly, the inspected connector 38 is positioned with respect to the pin block 24, and the terminal 38a is positioned with respect to the probe 54. Needless to say, the elasticity of pressing the pressing operation member 14 of the pressing spring 18 is set larger than the elasticity of separating the floating guide 26 of the float spring 34 from the pin block 24. In addition, since the depth of the guide hole 26b of the floating guide 26 is set to coincide with the height of the inspected connector 38, the pin block 24 of the inspected connector 38 that is fitted and inserted into the guide hole 26b. Since the probe 54 is disposed so that the side surface is in the same plane as the bottom surface of the concave portion 26c and the protruding height of the plunger is appropriate with reference to the bottom surface of the concave portion 26c, the probe is provided with an appropriate elasticity. 54 plungers can be brought into contact with the terminals 38a of the connector 38 to be inspected.

  The pressing operation member 14 is configured to be swingable between an open state and a pressed state by a swing shaft 16, and the structure thereof is relatively simple. Moreover, since the pressing block 22 is provided by the second swing shaft 20 on the distal end side of the pressing operation member 14, the floating guide 26 is correctly pressed toward the pin block 24 by the pressing block 22 in the approaching direction. Can do.

  By the way, in order to make the relay connector of the present invention correspond to the to-be-inspected side connector 38 of various sizes, first, the size and depth of the guide hole 26b of the floating guide 26 are appropriately determined according to the to-be-inspected side connector 38. Set the adjustment. The depth of the guide hole 26b can be adjusted by appropriately cutting the substrate mounting surface 26a. Also on the pin block 24 side, the position of the position adjustment block 48 is set appropriately in the insertion hole 50, so that the distance between the two rows of probe holes 46 and 52 is 2 of the connector 38 to be inspected. It is made to correspond to the distance d between the terminals 38a of a row | line | column. This can be achieved by appropriately drilling the position of the hole into which the positioning pin 56 is inserted. Needless to say, the probe 54 is inserted into the probe holes 46 and 52 so as to face the terminal 38a of the connector 38 to be inspected. As described above, the operation for making the relay connector of the present invention correspond to the connector 38 to be inspected of various sizes is relatively simple if each member immediately before final processing is prepared in advance.
