Description

  The present invention relates to a jig used when a connector is inserted into another part and fitted.

  It has been widely performed to automate the assembly of parts using an industrial robot, and the work of connecting a connector to other parts is no exception. For example, in Patent Document 1, an insertion pin of a base plate fixed to a robot arm is inserted into a connector, and a connector pin of the connector is inserted into a connection hole of a printed board. Next, the connector is pressed against the printed circuit board by the pusher, the robot arm is raised, and the base plate is separated from the connector to complete the connector insertion operation. This eliminates the relative positional error and variation of the connector pins with respect to the connector body, and the connector insertion operation is performed.

Japanese Utility Model Publication No. 5-31832

  However, even in the configuration described in Patent Document 1, if the relative position between the robot arm and the printed board is largely shifted in the first place, the connector pin of the connector held by the robot arm and the connection between the printed board and the printed circuit board. Since the relative position with respect to the hole is also greatly displaced, the connector cannot be inserted. Nevertheless, if the insertion is continued forcibly, the connector may eventually be damaged.

  The present invention has been made to solve the above-described problems. When the connector and the object to be fitted are to be inserted under a relative positional relationship where they cannot be inserted into each other, the connector is damaged. An object of the present invention is to obtain a connector insertion jig capable of preventing the above-described problem.

  The connector insertion jig according to the present invention includes a connector fixing portion having a fixed portion holding the connector at one end and a plate-shaped portion having a larger outer shape than the fixing portion fixed at the other end of the fixing portion, A base plate having a hole that is movably inserted along the insertion direction; and a spring that urges the plate-shaped portion toward the base plate along the insertion direction of the connector while the fixing portion is inserted into the hole. It is characterized by this.

  According to this invention, when inserting a connector, even if insertion operation is performed in the state in which the relative position of a connector and a to-be-fitted object has a shift | offset | difference, it can prevent that a connector is damaged.

Embodiment 1 FIG.
FIG. 1 shows a cross-sectional view of a connector insertion jig 1 according to Embodiment 1 of the present invention.
The connector insertion jig 1 includes a plate-shaped base plate 2, a connector fixing portion 3 that holds the connector 11, a screw 4 that is fixed to the base plate 2, and a screw head that has one end at the connector fixing portion 3 and the other end at the screw 4. And a spring 5 in contact with the back surface.
A hole 21 is formed in the base plate 2. The hole 21 is a hole having a size that the plate-like portion 31 of the connector fixing portion 3 described later cannot pass and the fixing portion 32 can pass. The base plate 2 is held by a robot arm (not shown) and moves in accordance with the operation of the robot arm.

  The connector fixing portion 3 includes a plate-like portion 31 that is a plate-like member, and a fixing portion 32 that can hold the connector 11 at one end and the plate-like portion 31 is fixed at the other end. The fixing portion 32 further includes a first member 32a and a second member 32b. When the connector 11 is sandwiched between the first member 32a and the second member 32b, the first member 32a and the second member 32b are screwed, for example, so that the connector 11 is fixed to one end of the fixing portion 32. . The plate-like portion 31 is located at the other end of the fixed portion 32 that is on the opposite side across the base plate 2 when viewed from the connector 11 fixed to the fixed portion 32. The plate-like portion 31 has a larger outer shape than the fixed portion 32.

  The plate-like portion 31 is slidable with respect to the screw 4 by inserting the screw portion of the screw 4 into the formed hole 31a. Further, the fixing portion 32 is inserted into the hole 21 of the base plate 2 and is slidable with respect to the base plate 2. That is, the connector fixing portion 3 is slidable with respect to the base plate 2 and the screw 4.

  The screw 4 passes through the plate-like portion 31 of the connector fixing portion 3, and one end thereof is fixed to the base plate 2 at the peripheral edge portion of the hole 21. For example, the screw 4 is fixed by screwing into a female screw (not shown) formed on the base plate 2. The other end is a screw head. Although two screws 4 are shown in FIG. 1, three or more screws may be provided. As the screw 4, a member not formed with a male screw fixed to the base plate 2 by welding or the like may be used instead. In short, a narrow-diameter portion on which the plate-like portion 31 can slide is inserted into the hole 31a, What is necessary is just a rod-shaped member by which the spring 5 is fixed to a large diameter part.

  The spring 5 is provided on the outer periphery of the threaded portion of the screw 4 and comes into contact with the plate-like portion 31 of the connector fixing portion 3 at one end, so that the plate-like portion 31 and the connector fixing portion 3 Urging in the connector insertion direction D. The other end is fixed to the back surface of the screw head of the screw 4 and the position thereof is maintained.

FIG. 2 shows a normal insertion state when the connector 11 is inserted into the fitting object 12 using the connector insertion jig 1. The to-be-fitted object 12 is a connector or the like on the receiving side with respect to the connector 11, and is mounted on a substrate (not shown), for example.
First, as shown in FIG. 2A, the base plate 2 is moved by a robot arm (not shown), and the connector 11 is arranged at a position facing the hole 12a of the object 12 to be fitted.
Then, as shown in FIG. 2B, the connector 11 is inserted into the hole 12a by the movement of the base plate 2 in the connector insertion direction D by the robot arm (not shown) and the biasing force of the spring 5, and the mating is performed. The object 12 is fitted.

  Further, the hole 21 of the base plate 2 is larger than the fixing portion 32 of the connector fixing portion 3, and the diameter of the hole 31 a of the connector fixing portion 3 is larger than the diameter of the screw portion of the screw 4. As a result, gaps are formed between the fixing portion 32 and the hole 21 and between the screw portion of the screw 4 and the hole 31a, and the connector fixing portion 3 is perpendicular to the connector insertion direction D with respect to the base plate 2 and the screw 4. Can move to some extent. Therefore, even if the connector 11 is slightly shifted from the hole 12a of the object 12 to be fitted and is opposed to the robot arm in the connector insertion direction D from the shifted position, the connector is fixed by the amount of the shift. The part 3 moves in a direction perpendicular to the connector insertion direction D, and the connector 11 is inserted into the fitting object 12.

Next, FIG. 3 shows an abnormal insertion state when the connector 11 is inserted into the fitting object 12 using the connector insertion jig 1.
First, as in FIG. 2 (a), the base plate 2 is moved by a robot arm (not shown) to attempt to place the connector 11 at a position facing the hole 12a. For example, the connector 11 may not be sufficiently opposed to the hole 12a due to a lack of appropriateness, as shown in FIG. This is a relative positional relationship in which the connector 11 cannot be inserted into the fitting object 12 even if the base plate 2 is moved in the connector insertion direction D as it is.

  From the state of FIG. 3A, the base plate 2 is moved in the connector insertion direction D by a robot arm (not shown). The amount of movement of the base plate 2 in the connector insertion direction D is the same as the amount of movement in the normal insertion state shown in FIG. Eventually, the tip of the connector 11 contacts the peripheral edge of the hole 12a. Even after the contact, the base plate 2 is further moved in the connector insertion direction D by the operation of the robot arm. At this time, the connector fixing portion 3 is connected to the base plate 2 and the screw 4 while compressing the spring 5 by the plate-like portion 31. Slide along the insertion direction D in the opposite direction.

  Finally, as shown in FIG. 3 (b), the compressed spring 5 absorbs the amount that the connector 11 cannot move in the direction of the connector insertion direction D because of contact with the peripheral edge of the hole 12a. It becomes. Thus, even if the connector fixing part 3 holding the connector 11 slides along the connector insertion direction D with respect to the base plate 2 and the screw 4, the connector 11 can be inserted into the hole 12a normally. The connector 11 is prevented from being damaged by preventing excessive force from being applied between the connector 11 and the object 12 to be fitted.

  Then, from the state shown in FIG. 3B, the connector 11 is inserted again as shown in FIG. Complete.

  In the above description, the connector 11 is inserted into the hole 12a by moving the base plate 2 with respect to the fixed object 12 to be fitted. However, the connector 11 may be inserted into the hole 12a by fixing the base plate 2 and moving the object 12 to be fitted by the robot arm.

The spring 5 is a spring having a spring constant corresponding to the insertion force required to insert the connector 11 into the fitting object 12. For example, when the number of pins of the connector 11 is large and the force required to insert the connector 11 is large, a spring having a large spring constant is used.
Further, as the screw 4, a screw having a length corresponding to the insertion amount of the connector 11 corresponding to the depth of the hole 12 a of the object to be fitted 12 is used. For example, when the depth of the hole 12a is deep and the insertion amount of the connector 11 is large, a long screw is used. As already described, the screw 4 may be a rod-shaped member, and in this case also, a rod-shaped member having a length corresponding to the amount of insertion of the connector 11 is used. However, by using a screw instead of a simple bar-like member, the screw 4 itself and the spring 5 can be easily replaced, and the workability is improved.

  Further, FIG. 1 illustrates a case where one hole 21 is provided in the base plate 2, and the connector fixing portion 3, the screw 4, and the spring 5 are provided in the hole 21. However, a plurality of holes 21 may be provided in the base plate 2, and the connector fixing portion 3, the screw 4, and the spring 5 may be provided for each hole 21. In this way, a plurality of connectors 11 can be inserted simultaneously using a single base plate 2. At this time, if the required insertion force and insertion amount differ for each connector 11, the spring constant of the spring 5 and the length of the screw 4 may be changed according to the corresponding connector 11.

FIG. 4 shows a modification of the connector insertion jig 1.
In FIG. 4A, the screw 6 is not provided, but the lid 6 fixed to the base plate 2 is provided so as to cover the plate-like part 31. The spring 5 is disposed inside the lid portion 6, one end of the spring 5 is in contact with the plate-like portion 31, and the other end is in contact with the bottom surface of the lid portion 6.

  In FIG.4 (b), the screw 4 is not provided but the plate-shaped part 31 processed into the hat shape is provided. One end of the spring 5 is fixed to the base plate 2, and the other end is fixed to the flange portion 31 b of the plate-like portion 31. In this case, the spring 5 extends to urge the plate-like portion 31 toward the base plate 2.

  In FIG. 4C, the screws 4 are not provided, and the flanges 32 c and 32 d are provided on the first member 32 a and the second member 32 b of the fixing portion 32. Further, one end of the spring 5 is brought into contact with the base plate 2 and the other end is brought into contact with the flanges 32c and 32d, and the spring 5 is provided on the side opposite to the plate-like portion 31 with the base plate 2 interposed therebetween.

Even if the connector insertion jig 1 is configured as shown in FIG. 4, the connector fixing portion 3 that holds the connector 11 can slide along the connector insertion direction D with respect to the base plate 2, and the connector 11 can be normally connected. Even when it cannot insert into the hole 12a of the to-be-fitted target object 12, damage to the connector 11 can be prevented by preventing an excessive force from being applied between the connector 11 and the to-be-fitted target object 12.
The point is that the spring 5 attaches the plate-like part 31 to the base plate 2 side along the connector insertion direction D in the state where the fixing part 32 is inserted into the hole 21 regardless of the presence of the screw 4 and the position of the spring 5. What is necessary is just to be constituted so However, a rod-like member such as a screw 4 is provided, a spring 5 is passed through the rod-like member, and one end of the spring 5 is fixed to the rod-like member, so that the rod-like member serves as a guide when the connector fixing portion 3 is slid. Can function. Further, as described above, by using the screw 4, the screw 4 itself and the spring 5 can be easily replaced.
In the case of the configuration shown in FIG. 4C, the spring 5 biases the plate-like portion 31 toward the base plate 2 via the flanges 32 c and 32 d of the fixed portion 32.

  As described above, according to the connector insertion jig 1 according to the first embodiment, when the connector 11 cannot be normally inserted into the hole 12a, the connector fixing portion 3 slides with respect to the base plate 2, and the connector 11 An excessive force is not applied to the object 12 to be fitted. This prevents the connector 11 from being damaged.

  In addition, a bar-like member fixed to the base plate 2 and provided so as to be movable through the plate-like portion 31 along the insertion direction D of the connector 11 is provided, and the spring 5 is fixed to the bar-like member. The rod-shaped member functions as a guide when the connector fixing portion 3 slides.

  Further, the spring 5 has a spring constant corresponding to the insertion force of the connector 11, and the rod-shaped member has a length corresponding to the insertion amount of the connector 11. By appropriately designing the spring 5 and the rod-shaped member, it can be used as an insertion jig for various types of connectors 11.

  A plurality of holes 21 are formed in the base plate 2, and the connector fixing portion 3, the spring 5, and the rod-shaped member are provided for each of the plurality of holes 21. Therefore, a plurality of connectors 11 can be inserted simultaneously.

  Further, the rod-like member penetrates the plate-like portion 31 with a gap, and the fixing portion 32 is inserted into the hole 21 with a gap. Accordingly, even if the connector 11 is slightly shifted from the hole 12a of the object 12 to be fitted, the connector fixing portion 3 moves in the direction perpendicular to the connector insertion direction D by the amount of the shift, and the connector 11 Is inserted.

  The rod-shaped member is a screw 4. By using the screw 4 as the rod-shaped member, the screw 4 itself and the spring 5 can be easily replaced, and workability is improved.
