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 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, and these substrates are arranged respectively. Some are electrically connected via connectors. 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. A probe is disposed in this probe unit. And the terminal of a jig | tool side connector is electrically connected to the terminal provided in the insulation relay board | substrate, and the probe of a probe unit contact | abuts 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. Accordingly, 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 parts to be replaced.
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.

  Some digital camera boards have a board-side connector disposed at one end and a CCD camera element disposed at the other end. In order to inspect such a substrate, with the inspected substrate side connector mounted on the inspection apparatus being electrically connected to the measuring instrument, the CCD camera element is opposed to the lens provided in the inspection apparatus and the optical axis thereof is set. Match. Therefore, the inspection substrate is positioned and arranged in the inspection apparatus so that the CCD camera element is at a fixed position with respect to the lens, and the inspection side is arranged on the inspection substrate positioned in the inspection apparatus. In order to connect the relay connector to the connector, the relay connector must also be fixed to the inspection device by adjusting its position. However, the probe disposed in the relay connector is a consumable item and needs to be replaced. If the relay connector is removed from the inspection device every time the probe is replaced, it is necessary to adjust the fixing position when attaching the probe again, which is complicated.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a relay connector that does not require position adjustment when the probe is replaced and reattached, and the operation is easy.

  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. The guide member is provided with a guide hole that is positioned by fitting and inserting the connector to be inspected, and a pin block made of an insulating material is disposed in the guide member, and the pin to be inspected is positioned on the pin block. A probe is arranged so that one end can be elastically contacted with a terminal of the side connector, a wiring board is fixed to the pin block, and the other end of the probe is elastically contacted with the wiring board, and the measuring instrument is electrically connected A wiring cable for connection is provided, and the pin block and the wiring board are screwed into the base member fixed to the inspection device by screwing from the pin block side. It is configured to constant.

  Then, a hole into which a tool can be inserted may be formed in the guide member so as to face the screw.

  Further, the wiring board may be fixed to the pin block by screwing and inserting a screw from the wiring board side.

  Further, the guide member is controlled to be separated from the pin block in the axial direction of the probe and can be moved in the separation direction, and the guide member is elastically biased from the pin block in the separation direction. It is also possible to configure.

  In the relay connector according to claim 1, the pin block and the wiring board are fixed to the base member fixed to the inspection device by screwing and inserting the screw from the pin block side. Thus, the guide member disposed on the pin block, the wiring board, and the pin block can be removed from the base member. The base member remains fixed to the inspection device. If the probe is appropriately replaced on the side of the pin block and the wiring board removed from the base member, and the pin block and the wiring board are attached to the base member again, the position of the base member is adjusted relative to the inspection apparatus. Since it is maintained, it is not necessary to adjust the position again by exchanging the probe.

  In the relay connector according to claim 2, the guide member is provided with a hole through which the tool can be inserted so as to face the screw for fixing the pin block and the wiring board to the base member. The pin block and the wiring board can be removed from the base member without removing from the block.

  Further, in the relay connector according to claim 3, since the wiring board is fixed to the pin block by screwing the screw from the wiring board side, the pin block removed from the base member is attached to the wiring board. If this wiring board is removed with the side facing up, the probe will not fall off from the pin block.

  Furthermore, in the relay connector according to claim 4, the guide member can be separated from the pin block in the axial direction of the probe and can be moved in the separation direction, and the guide member is separated from the pin block. Since the guide member is elastically biased in the direction, if the guide member is not pressed and moved against the pin block against the elastic bias, the probe is connected to the terminal of the connector to be inspected fitted into the guide hole of the guide member. Does not touch. Therefore, when inserting the connector to be inspected into the guide hole, the probe comes into contact with the terminal of the connector to be inspected in the posture that has not been correctly inserted, and either or both of the terminal of the connector to be inspected and / or the probe There will be no damage.

  1 to 17, in the relay connector of the present invention, a hinge member 12 is fixed to a base member 10 with a screw 10a, and swings by a swing shaft 16 having a pressing operation member 14 penetrating through the hinge member 12. Arranged freely. 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 as a guide member with respect to the pin block 24 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 and the distance in the separating direction. Are regulated and 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 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 back side of the substrate mounting surface 26a with a penetrating guide hole 26b as a 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 floating guide 26 is positioned on the pin block 24. 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 distance between the probe hole 52 of the position adjusting block 48, the lower pin block 40, and the probe hole 46 of the upper pin block 42 corresponds 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 is appropriately fixed to the inspection apparatus 60 in advance by a fixing screw 10b. 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 one embodiment of the relay connector of the present invention are 27 mm in height, 26 mm in width, and 60 mm in length. If removed from the inspection device 60, the external dimensions can be held by hand.

  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 board to be inspected 36 itself, and no force to shift the position of the inspected connector 38 is applied to the board to be inspected 36. While the pressing operation member 14 is maintained in the open state, the engagement protrusion 14a of the pressing operation member 14 is engaged with the engagement receiving portion 26f of the floating guide 26, and the floating guide 26 is on the pin block 24 side. There is no such thing as inadvertent movement. 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 due to contact. When the pressing operation member 14 is closed and pressed by the elasticity of the pressing spring 18, the floating guide 26 moves linearly to the pin block 24 side by the linear guide 30, and the terminal of the connector 38 to be inspected. The plunger of the probe 54 comes into contact with 38a. 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. 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. Compared to new processing and manufacturing, it is possible to respond quickly.

  The distance at which the floating guide 26 is separated from the pin block 24 in the separating direction can be arbitrarily adjusted by the floating pin 30. However, when the distance at which the floating guide 26 is separated from the pin block 24 is changed by use, What is necessary is just to adjust the screwing insertion state of the adjustment screw 32a of the floating pin 32 by inserting a tool appropriately from the adjustment hole 14d formed in the operation member 14. When the probe 54 is damaged and replaced, the hinge member 12 is removed from the base member 10 with the pressing operation member 14 attached, and a tool is inserted from the hole 26e formed in the floating guide 26. The screw 24a is removed from the base member 10. Further, with the removed pin block 24 facing the wiring board 28, the screw 28 a is removed and the wiring board 28 is removed from the pin block 24. Then, only the probe 54 that is damaged and needs to be replaced may be taken out of the probe holes 46 and 52 and replaced.

  Although the wiring board 28 is fixed to the pin block 24 with screws 28 a, the wiring board 28 may be bent due to soldering heat or the like, and its rear end side may be lifted from the base member 10. Thus, the wiring board 28 is pressed against the base member 10 by the rib 12a provided on the hinge member 12.

  When the substrate to be inspected 36 is a camera module, the CCD camera element 58 is disposed on the other end side of the substrate to be inspected 36, that is, on the opposite side to the side on which the connector 38 to be inspected is provided. In some cases, the positions where the inspected connector 38 and the CCD camera element 58 are disposed are relatively close as shown in FIG. Therefore, the upper end of the pressing operation member 14 is formed as a chamfered slanted surface 14b, so that the field of view above the CCD camera element 58 is wide and wide, and there is no obstacle in the field of view. Can be opposed to the lens 62 provided in the inspection device 60 for inspecting.

  Here, as shown in FIG. 15, the relay connector of the present invention is fixed to the inspection apparatus 60, and one end portion of the inspected substrate 36 provided with the CCD camera element 58 is disposed on the inspection apparatus 60. In some cases, the inspected connector 38 disposed on the other end of the inspected substrate 36 is connected to the relay connector of the present invention. In such a case, it goes without saying that the pedestal 64 is positioned and fixed with respect to the inspection apparatus 60 in order to arrange the optical axes of the CCD camera element 58 and the lens 62 so as to coincide with each other. In addition, the relay connector of the present invention must be adjusted in position and fixed to the inspection device 60. Therefore, when the probe 54 is damaged and replaced, the entire relay connector of the present invention is removed from the inspection device 60. When the probe 54 is replaced and attached to the inspection device 60 again, a complicated position is required each time. Adjustment work is required. However, in the present invention, the hinge member 12 is removed from the base member 10 with the pressing operation member 14 still attached, a tool is inserted through the hole 26e formed in the floating guide 26, and the screw 24a is inserted into the base member. Remove from 10. Then, as shown in FIG. 17, the pin block 24 and the wiring board 28 are removed from the base member 10 in a state where the base member 10 is fixed to the inspection apparatus 60 with the fixing screw 10 b. Therefore, after removing only the probe 54 that is damaged and needs to be replaced from the probe holes 46 and 52 and replacing it, the above-described removed members may be sequentially assembled to the base member 10 again. The base member 10 itself is not removed from the inspection apparatus 60, and the state in which the position is adjusted with respect to the inspection apparatus 60 is maintained. Therefore, the relay connector of the present invention reassembled to the base member 10 is in a state where the position is adjusted with respect to the inspection device 60 and does not require a complicated position adjustment operation. In the example shown in FIG. 15, the wiring cable 66 having one end electrically connected to the wiring board 28 by soldering or the like is appropriately electrically connected to the inspection device 60 at the other end. Although 60 is also a measuring device, a measuring device may be provided separately from the inspection device 60 to which the relay connector of the present invention is fixed, and the relay connector and the measuring device may be appropriately electrically connected by the wiring cable 66.
