  FIG. 1A is a top view of a connector removal jig (hereinafter referred to as a removal jig) 1 according to the first embodiment, and FIG. 1B is a side view of the removal jig 1 according to the first embodiment. The removal jig 1 includes a main body part 10, a support part 20, and a holding part 30. Although the main-body part 10, the support part 20, and the holding | maintenance part 30 are metal, for example, it is not limited to this, A product made from a synthetic resin may be sufficient. The main body 10 has a rod shape extending in one direction, that is, a predetermined direction. The support portion 20 protrudes from the main body portion 10 in another direction different from the one direction. The holding portion 30 protrudes along the direction in which the support portion 20 protrudes from the main body portion 10, that is, the other direction. That is, the support portion 20 and the holding portion 30 protrude on the same side with respect to the main body portion 10. The support part 20 protrudes from the first position of the main body part 10. The holding part 30 protrudes from a second position different from the first position of the main body part 10. The base end portion 22 of the support portion 20 is rotatably connected to the first end portion 11 of the main body portion 10 by a support pin AP. As shown in FIG. 1A, a slit 16 is formed on the first end 11 side of the main body 10. The support portion 20 has a thin plate shape, and the support portion 20 is set to a thickness that can rotate with respect to the main body portion 10 and enter the slit 16.

  Unlike the support portion 20, the holding portion 30 is fixed between the first end portion 11 and the second end portion 12 of the main body portion 10 so as not to rotate. A fixing piece 37 is fixed to the surface of the holding unit 30 on the support unit 20 side. The holding portion 30 is formed with a concave portion 33 and a convex portion 34 on the surface facing the fixed piece 37. The base end portion 32 of the holding portion 30 is fixed to the main body portion 10 with two screws S. The fixing piece 37 is fixed to the holding part 30 by a fixing pin FP. The fixing pin FP is screwed with the holding unit 30. The fixing piece 37 can be pulled away from the holding part 30 by adjusting the screwing amount between the fixing pin FP and the holding part 30. In the state shown in FIG. 1B, the fixed piece 37 is fixed to the holding unit 30. A convex portion 38 is formed on the surface of the fixed piece 37 facing the holding portion 30. In a state where the fixed piece 37 is fixed to the holding part 30, a predetermined space is formed between the holding part 30 and the fixed piece 37. This space will be described in detail later. The convex portion 34 formed on the holding portion 30 protrudes toward the fixed piece 37, and the convex portion 38 formed on the fixed piece 37 protrudes toward the holding portion 30.

  A grip G for an operator to hold is fixed to the second end 12 of the main body 10. The grip G is an example of a grip portion that is gripped when an operator operates the main body portion 10. The grip G is made of, for example, a synthetic resin. Note that the grip G may not be provided.

  Next, the connector 100 mounted on a printed circuit board (hereinafter referred to as a board) PS will be described. FIG. 2 is a perspective view of a plurality of connectors 100 mounted on the substrate PS. The connector 100 includes a body portion 110 extending in a predetermined direction, a latch portion 120 formed at a first end portion of the body portion 110, and a latch portion 130 formed at a second end portion of the body portion 110. The body part 110 and the latch parts 120 and 130 are made of synthetic resin. A plurality of metal terminal pins 115 are formed on the bottom surface of the body portion 110.

  The terminal pin 115 is inserted into the through hole of the substrate PS. The through hole is electrically connected to a conductor pattern formed in the inner layer or the outer layer of the substrate PS. By inserting the terminal pin 115 into the through hole, the terminal pin 115 of the connector 100 and the conductor pattern of the substrate PS are electrically connected. An insertion port 117 is formed in the body portion 110 over the longitudinal direction. By inserting the terminal portion of the mating connector into the insertion port 117, the conductor pattern of the board PS and the mating connector are conductively connected via the connector 100.

  The latch portions 120 and 130 prevent the mating connector from being removed from the insertion port 117 by engaging with the mating connector inserted into the insertion port 117. By operating the latch portions 120 and 130, the engagement with the counterpart connector is released, and the counterpart connector can be detached from the connector 100. The latch portions 120 and 130 protrude upward from the end portion of the body portion 110.

  The connector 100 is mounted on the substrate PS by press-fit mounting. That is, the terminal pin 115 of the connector 100 is press-fitted into the through hole of the substrate PS. Therefore, the connector 100 is mounted on the substrate PS without using solder. The operation of removing the connector 100 from the board PS is performed, for example, in order to replace the connector 100 with a normal connector when the connector 100 mounted on the board PS is defective.

  FIG. 3 is a side view of the connector 100. The front end portion 133 of the latch portion 130 slightly protrudes in the horizontal direction toward the outside of the body portion 110. A concave portion 134 is formed on the outer surface of the latch portion 130, and a concave portion 138 is formed on the surface of the latch portion 130 on the body portion 110 side. The latch unit 120 has the same shape as the latch unit 130, and has a front end portion 123 and concave portions 124 and 128.

  FIG. 4 is a view of the removal jig 1 set on the connector 100. In the set state, the support portion 20 is located on the latch portion 120 side of the insertion port 117 of the connector 100. In other words, the support portion 20 is located closer to the latch portion 120 than the latch portion 130. The holding unit 30 holds the latch unit 130. In other words, the holding unit 30 is located closer to the latch unit 130 than the latch unit 120. In the set state, the support part 20 and the holding part 30 are substantially parallel and substantially perpendicular to the substrate PS. The main body 10 is substantially parallel to the substrate PS and the connector 100.

  The removal jig 1 is set on the connector 100 as follows. First, the fixing pin FP is adjusted, and the fixing piece 37 is pulled away from the holding portion 30. Next, the concave portion 33 is engaged with the distal end portion 133 and the convex portion 34 is engaged with the concave portion 134. Next, the fixing pin FP is adjusted, and the fixing piece 37 is brought into contact with the holding portion 30 so that the concave portion 138 is engaged with the convex portion 38 of the fixing piece 37. Next, the fixing piece 37 is fixed to the holding portion 30 by the fixing pin FP. In this way, the holding unit 30 holds the latch unit 130. Next, the support unit 20 is inserted into the insertion port 117 at a position on the latch unit 120 side in a state where the support unit 20 is perpendicular to the substrate PS. Thereby, the support part 20 is located on the latch part 120 side, and the holding part 30 is located on the latch part 130 side. Thereby, the removal jig 1 is set in the connector 100.

  In this state, the operator grasps the grip G and rotates the main body portion 10 around the support portion 20 in the counterclockwise direction. Specifically, the main body 10 is rotated with the support pin AP as a fulcrum. Accordingly, the holding unit 30 moves in a direction away from the substrate PS while the support unit 20 supports the main body unit 10 and pushes the latch unit 120 side of the connector 100 toward the substrate PS. Thereby, the latch part 130 is separated from the substrate PS, and the body part 110 is peeled in order from the latch part 130 side to the latch part 120 side. In this way, the connector 100 can be removed from the board PS. As described above, the removal jig 1 of this embodiment uses the latch portion 130 provided in the connector 100 to pull up the latch portion 130 to remove the connector 100 from the board PS. Details will be described later.

  Next, the deformation of the connector 100 when the connector 100 is detached from the board PS by pulling up the latch portion 130 from the board PS will be described. FIG. 5A is an explanatory diagram of deformation of the connector 100 when the connector 100 is detached from the board PS. FIG. 5B is a partially enlarged view of FIG. 5A. In FIG. 5A and 5B, each part is typically described for easy understanding. 5A and 5B show the connector 100 before and during removal from the substrate PS. 5A and 5B, the latch part 130 in the middle of the body part 110 being peeled from the substrate PS is described with reference numerals of the latch parts 130 ′ and 130 ″. The boundary positions between the part peeled from the substrate PS and the part not peeled are defined as boundary positions H1 and H2. 5A and 5B, the terminal pins 115 are not shown.

  As shown in FIG. 5B, before peeling, it is ideal that the latch portion 130 is pulled upward in the Z direction perpendicular to the surface of the substrate PS, or in the upper left direction inclined slightly to the left side from the Z direction. When the latch part 130 is pulled up in a direction slightly tilted to the right side from the Z direction, a force acts in the X direction perpendicular to the Z direction on the part of the body part 110 peeled from the substrate PS, so that the body part 110 becomes X This is because there is a possibility of breaking in the direction.

  When the latch part 130 is pulled up and the body part 110 is peeled to the boundary position H1, the peeling part R1 which is a part of the body part 110 is peeled from the substrate PS, and the latch part 130 ′ is slightly more than the latch part 130. It is located in the upper left in the figure. At this time, the distance D1 between the latch parts 120 and 130 'is shorter than the distance D between the latch parts 120 and 130. This is because a part of the body part 110 is peeled off from the substrate PS and the latch part 130 ′ is inclined toward the latch part 120. The peeling portion R1 is slightly curved so that the bottom surface of the peeling portion R1 is convex toward the substrate PS. Since the body part 110 is made of synthetic resin, it bends in this way. Therefore, the distance D1 is shorter than the distance D because not only a part of the body portion 110 is peeled from the substrate PS but also the peeled portion R1 is curved.

  Ideally, the latch portion 130 'is pulled up in the Z' direction, which is a direction perpendicular to the longitudinal direction of the peeling portion R1 peeled from the substrate PS. For example, when the latch part 130 ′ is pulled up in the Z direction perpendicular to the substrate PS, a force in the X ′ direction substantially orthogonal to the Z ′ direction acts on the peeling portion R 1. Since the part of the body part 110 other than the peeling part R1 remains fixed to the substrate PS, the peeling part R1 is pulled in the X ′ direction (longitudinal direction of the peeling part R1). Therefore, depending on the magnitude of the force that pulls up the latch portion 130 ′, the root portion of the latch portion 130 may be broken.

  Further, when the body portion 110 is peeled to the boundary position H2, the peeled portion R2 is peeled from the substrate PS, and the latch portion 130 ″ is located at the upper left in the drawing relative to the latch portion 130. At this time, the distance D2 between the latch units 120 and 130 '' is shorter than the distance D1 between the latch units 120 and 130 '. This is because the peeling portion R2 is longer than the peeling portion R1, and the peeling portion R2 is inclined more greatly than the peeling portion R1. Moreover, since peeling part R2 is longer than peeling part R1, it is because the peeling part R2 is curved more largely than peeling part R1. Therefore, the longer the peeled peeled portion, the greater the curvature of the curved peeled portion. For this reason, the longer the peeled portion, the greater the degree of shortening of the distance between the latch portions 120 and 130 due to the curved peeled portion.

  Also in the latch part 130 ″, it is desirable to pull up in the Z ″ direction, which is a direction substantially perpendicular to the longitudinal direction of the peeling portion R2 peeled off from the substrate PS. Also in this case, for example, when the latch portion 130 ″ is pulled up in the Z ′ direction or the Z direction, a force in the X ″ direction perpendicular to the Z ″ direction acts on the body portion 110. For this reason, if the force in the Z ′ direction is large, a large force acts on the latch portion 130 ″ in the X ′ direction, the peeling portion R2 is pulled, and the peeling portion R2 may be broken.

  As described above, the distance between the latch portions 120 and 130 gradually decreases as the body portion 110 is peeled from the substrate PS. This is because, as described above, the peeled portion becomes not only gradually longer, but the peeled portion is curved, and the larger the peeled portion, the larger the curvature of the curve. The removal jig 1 of the present embodiment can remove the connector 100 from the board PS in consideration of such deformation of the connector 100.

  6A to 7B are explanatory views of the removal of the connector 100 by the removal jig 1. In addition, in FIG. 6A-7B, in order to understand easily, each part is shown typically. FIG. 6A shows a state where the removal jig 1 is set on the connector 100. 6B is a cross-sectional view taken along the line AA in FIG. 6A. The distal end portion 21 of the support portion 20 is inserted into the insertion port 117, the holding portion 30 is held by the latch portion 130, and the removal jig 1 is set on the connector 100. Let E be the distance between the support pin AP and the holding portion 30 in the longitudinal direction of the main body 10. Further, let L be the distance between the side surface of the distal end portion 21 of the support portion 20 and the side surface of the distal end portion 31 of the holding portion 30 facing each other. The distance E is, for example, two thirds or more of the length in the longitudinal direction of the connector 100, but is not limited thereto. The distance E is, for example, about 120 mm, and the height of the support portion 20 is 3 to 12 mm, but is not limited thereto. In addition, the size of each member may be appropriately changed according to the size and shape of the connector 100.

  After setting the removal jig 1 on the connector 100, the operator pushes the main body 10 in the direction from the holding part 30 toward the support part 20 (the direction of -X in the figure), while using the support pin AP as a fulcrum. The main body 10 is rotated counterclockwise. The −X direction means a direction parallel to the plane of the substrate PS. Accordingly, as shown in FIG. 7A, the support portion 20 is inclined in the insertion port 117 so that the distal end portion 21 of the support portion 20 approaches the holding portion 30, and the first end portion 11 of the main body portion 10 is latched. It moves outside the part 120. Specifically, when the base end portion 22 side of the support portion 20 is pushed in the −X direction, the support portion 20 comes into contact with the latch portion 120, whereby the distal end portion 21 of the support portion 20 moves to the X direction side and moves to the base. The end 22 moves in the −X direction. In this way, the support portion 20 is inclined toward the holding portion 30 side. In other words, the support part 20 is inclined so that the distance between the tip part 21 of the support part 20 and the tip part 31 of the holding part 30 is shortened. Thereby, the distance L1 between the side surface of the distal end portion 21 of the support portion 20 and the side surface of the distal end portion 31 of the holding portion 30 is shorter than the distance L in the state where the removal jig 1 is set.

  Further, when the support portion 20 is tilted, the support pin AP moves in the −X direction and the −Z direction. The −Z direction is a direction perpendicular to the −X direction and toward the substrate PS. In this way, the position of the support pin AP that becomes the fulcrum of rotation of the main body 10 moves. For this reason, it is considered that the direction of the force acting on the latch portion 130 by the holding portion 30 is close to the Z ′ direction.

  When the operator further rotates the main body part 10 in the direction from the holding part 30 toward the support part 20 and rotates it counterclockwise, the support part 20 is further inclined toward the main body part 10 side. Thereby, the distance L2 between the side surface of the distal end portion 21 of the support portion 20 and the side surface of the distal end portion 31 of the holding portion 30 is shorter than the distance L1. Further, the support pin AP further moves in the −X direction and the −Z direction. In this way, the position of the support pin AP that becomes the fulcrum of rotation of the main body 10 moves. For this reason, the direction of the force acting on the latch part 130 by the holding part 30 seems to be a direction close to the Z ″ direction. The distance E is not changed regardless of the inclination of the support portion 20, and the distance between the support pin AP and the latch portion 130 is also unchanged.

  As described above, the distance between the distal end portion 21 of the support portion 20 and the distal end portion 31 of the holding portion 30 becomes shorter as the connector 100 is peeled from the substrate PS. As described above, the connector 100 is also deformed so that the distance between the latch portions 120 and 130 becomes shorter as the peeling progresses. Accordingly, the distance between the distal end portion 21 of the support portion 20 and the distal end portion 31 of the holding portion 30 is also shortened so as to correspond to the deformation of the connector 100. In addition, the position of the support pin AP also moves in the −X direction and the −Z direction when the support portion 20 is tilted. This means that the position of the rotation fulcrum of the holding unit 30 moves in the −X direction and the −Z direction. Accordingly, the posture of the holding unit 30 that holds the latch unit 130 is changed corresponding to the deformation of the connector 100. Thereby, the latch part 130 is pulled up without a large tensile force in the longitudinal direction acting on the peeled portion of the body part 110. Thereby, the connector 100 can be removed from the board PS without being damaged.

  Immediately before the peeling of the connector 100 is completed, the connector 100 is inclined at a steeper angle than the state shown in FIG. 7B. Thereby, the peeling of the connector 100 is promoted by the action of the elastic restoring force that the body portion 110 of the connector 100 tries to return to a straight line.

  Note that a plurality of metal terminal portions are provided in the insertion port 117. When the distal end portion 21 of the support portion 20 is inserted into the insertion port 117, the distal end portion 21 is sandwiched from both sides by the terminal portion in the insertion port 117. Thereby, even if the support part 20 inclines, it is hold | maintained with the terminal part in the insertion port 117 with that state. Thereby, even if the support part 20 inclines, the main-body part 10 can be rotated stably by using the support part 20 as a fulcrum. Moreover, since the support part 20 is pressed against the board | substrate PS toward the board | substrate PS, when pulling up the latch part 130, it is preventing that the board | substrate PS floats with the connector 100. FIG. Further, since the support portion 20 is inserted into the insertion port 117 of the connector 100 and the connector 100 is removed, the substrate PS is prevented from being damaged by the support portion 20. This is because when the connector 100 is replaced, it is desired that the substrate PS to be reused is not damaged.

  Next, the case where the connector 100 is removed from the board PS without considering the deformation of the connector 100 will be described. First, a case where an operator removes the connector 100 with pliers will be described. FIG. 8A is an explanatory diagram when the connector 100 is removed with pliers. It is assumed that the operator pulls the latch part 130 with the pliers PC vertically upward (Z direction) with respect to the substrate PS.

  If the operator pulls up the pliers only vertically upward without moving the pliers in the vertical posture in the vertical posture, it is considered that a tensile force acts on the peeling portion R1 in the X direction, that is, the longitudinal direction of the peeling portion R1. When the tensile force in the X direction acting on the peeling portion R1 exceeds the elastic limit of the body portion 110, the root portion of the latch portion 130 may be broken as shown in FIG. 8A. Alternatively, the body part 110 may be broken near the boundary position H1. Further, for example, when the operator moves the pliers not only vertically upward in the vertical posture but also in the horizontal direction (−X direction) as the peeling of the connector 100 progresses, the pliers are maintained in the vertical posture. Therefore, there is a possibility that the root portion of the latch portion 130 may be lost during the peeling process.

  In this case, the operator needs to grasp the latch portion 120 again and peel it off so that the connector 100 does not break. In this case, the operator is forced to perform a plurality of operations in order to remove one connector 100. Further, in order to remove the connector 100 so as not to be damaged, it is necessary to pull the latch portion 130 while changing the posture of the pliers PC in consideration of the deformation of the connector 100 during peeling. Therefore, a skilled work is required for the worker, and the work using the pliers is difficult.

  Next, a case where the connector 100 is detached using a removal jig 1x having a structure different from that of the removal jig 1 of the present embodiment will be described. FIG. 8B is an explanatory diagram when the connector 100 is detached using a removal jig 1x having a structure different from that of the removal jig 1 of the present embodiment. The support portion 20x of the removal jig 1x holds the latch portion 120. For this reason, the support part 20x cannot incline with respect to the latch part 120, and the position of the support pin AP cannot move. For this reason, the holding | maintenance part 30 rotates counterclockwise by using the support pin AP which does not move as a fulcrum. When the main body 10 rotates counterclockwise with the support pin AP as a fulcrum, the tip 31 of the holding part 30 tends to move not only in the Z direction but also in the X direction. If a large force in the X direction acts on the peeling portion R1 and exceeds the elastic limit, the root portion of the latch portion 130 may be broken. For this reason, the connector 100 cannot be detached from the board PS without damaging the connector 100.

  Here, comparing FIG. 7A and FIG. 8B, since the support pin AP moves in the removal jig 1 of the present embodiment, the component in the X direction of the force acting on the latch portion 130 by the holding portion 30 is removed. The force acting on the latch part 130 by the holding part 30 of the outer jig 1x is considered to be smaller than the X-direction component. For this reason, in this embodiment, the connector 100 can be removed without exceeding the elastic limit of tension in the longitudinal direction of the body portion 110.

  In the case of the present embodiment, while the connector 100 is being peeled from the substrate PS, in other words, while the main body portion 10 is being rotated, the support portion 20 is inclined toward the holding portion 30 and the support pins AP are inclined. The position moves. Thereby, it is possible to cope with the deformation of the connector 100 during peeling, and the connector 100 can be peeled from the substrate PS without applying a large force in the longitudinal direction of the body portion 110. For this reason, the connector 100 can be removed even if it is not a skilled worker.

  9A to 11 are explanatory views of the removal jig 1a of the first modification. In the following modifications, the same or similar members as those in the above embodiment are given the same or similar reference numerals. The movable pin FPa passes through the holding portion 30a and the fixed piece 37a. Both ends of the movable pin FPa are in a flange shape so that the movable pin FPa is not detached from the holding portion 30a and the fixed piece 37a. The movable pin FPa penetrates the holding portion 30a and the fixed piece 37a so as to be slidable in the axial direction. A lock piece 35a is rotatably connected to the side surface of the holding portion 30a. The lock piece 35a is substantially L-shaped in a side view. A locking projection 39a is formed on the side surface of the fixed piece 37a.

  As shown in FIG. 9A, the fixing piece 37a is pulled away from the holding portion 30a, and the removal jig 1a is set so that the latch portion 130 is sandwiched between the holding portion 30a and the fixing piece 37a. Next, as shown in FIG. 9B, the removal jig 1 a is moved so that the concave portion 33 of the holding portion 30 a engages with the distal end portion 133 of the latch portion 130, and the distal end portion 21 of the support portion 20 is moved to the connector 100. Insert into the insertion port 117. Next, as shown in FIG. 10A, the movable pin FPa is pulled toward the grip G, and the fixed piece 37a is brought into contact with the holding portion 30a.

  Next, as shown in FIG. 10B, the lock piece 35a is rotated to engage the lock piece 35a with the locking projection 39a. Thereby, the fixed piece 37a is locked in the state fixed to the holding | maintenance part 30a. The lock piece 35a is kept engaged with the locking protrusion 39a by its own weight. As a result, the holding unit 30 a holds the latch unit 130. In this state, the operator can peel the connector 100 from the substrate PS as shown in FIG. 11 by operating the removal jig 1a in the same manner as the removal jig 1 of the first embodiment described above. .
