In a method of attaching a positioning jig to a substrate or another member for fitting and connecting a connector within a fitting tolerance, a cost for providing the positioning jig is reduced. And the number of work steps increases. In addition, the method of connecting with a cable or the like also has a problem that the cost is high and human labor is required, so that the assembling work increases.

[0005] Further, the method of mounting the board on the case or the cover, positioning the case or the cover with each other, and fitting / connecting the connector mounted on the board also involves a positioning error between the case and the cover, and a method of fitting the case and the cover. Accumulated errors such as board mounting and positioning errors and connector mounting and positioning errors to the board will occur as connector fitting and connection position errors.Therefore, it is impossible to control this cumulative error within the fitting tolerance of the connector. Not easy. SUMMARY OF THE INVENTION It is an object of the present invention to provide a method and a board for connecting a connector mounted on a board which solves the above-mentioned problems of the prior art, reduces costs and facilitates fitting and connection work.

[0006]

Means for solving the problems A positioning guide portion for mutually positioning the substrate and other members is formed at a corresponding end of a substrate on which the connector is mounted and another member such as the substrate, and the connector is mounted. At the time of connection, the positioning guide portion first contacts to position the substrate with respect to the other member, and then the connector is fitted.

The positioning guide portion includes a projection formed at one end of the substrate and the other member, and a concave portion which engages with the projection formed at the other corresponding end. In the fitted state, the contact is released, and in the fitted / connected state, no stress is applied to the connector. Further, by movably attaching the substrate to a member such as a case or a cover, movement for positioning the substrate is facilitated.

[0008]

FIG. 1 is a view showing one embodiment of the present invention. FIG. 1 (a) is a front view, and FIG. 1 (b) is a side view thereof. One end 1a of the connector is attached and fixed to the end of the board 3 on which the electric circuit is mounted. The end of the board 3 to which the connector 1a is attached protrudes at both ends of the connector 1a and the tip is formed in an arc shape. Positioning guide 6
a. The board 3 is attached to a member to which the board 3 is attached, in this embodiment, to a cover 5 of a control device.
In (a), it is movably attached in the left-right direction (the width direction of the connector).

On the other hand, the other connector 1b fitted and connected to the one connector 1a is attached to an end of the board 4 on which the electric circuit is mounted, which is attached to the case of the control device, opposite to the board 3. I have. In the example shown in this embodiment, one of the connectors mounted and fixed on the board 3 side is a female connector, and the other of the connectors mounted and fixed on the board 4 side is an example of a male connector. However, the reverse case may be adopted. The end of the substrate 4 is cut into a concave shape, and the other connector 1b of the connector is attached and fixed at a position substantially at the center of the concave cut. Both ends of the cut of the concave portion are formed in an arc shape, and slightly project inward (center side of the concave portion) to form a positioning guide portion 6b.

The distance between the ends of the positioning guide portions 6a, 6a formed on the substrate 3 that protrudes maximally outside the arc-shaped portion (outside from the connector 1a) and the positioning guide formed on the substrate 4 The distance between the maximally inwardly protruding ends of the arc-shaped portions of the portions 6b, 6b is formed with substantially the same dimensions. Then, the connector 1a is positioned such that the distal end surface of the connector 1a is located on a line connecting the positions at which the outer ends of the arc-shaped portions of the positioning guide portions 6a, 6a project outward in the maximum direction.
Is fixed to the substrate 3. The connector 1b is attached and fixed to the substrate 4 such that the distal end surface of one of the connectors 1b is located on a line connecting the ends of the arcuate portions of the positioning guide portions 6b, 6b that project inward to the maximum. .

In order to fit and connect the female connector 1a and the male connector 1b, the cover 5 is moved downward in FIG.
When the female connector 1a is slightly displaced in the left-right direction from the position at which the connector is fitted, or when the opposing surfaces of the female connector 1a and the male connector 1b approach each other in an inclined manner instead of being parallel, first, the tip of the female connector 1a The positioning guides 6a, 6a protruding from the surface come into contact with the positioning guides 6b, 6b of the substrate 4. Both positioning guides 6a, 6
Since a, 6b and 6b are formed in an arc shape, the substrate 3
Of the positioning guides 6a, 6a, 6
1b, the substrate 3 moves in the left-right direction and the inclination is corrected, and as shown in FIG. 2, between the largest ends of the arc-shaped projections of the positioning guide portions 6a, 6a and the positioning guide. Guided positioning is performed so that the minimum distance between the arc-shaped protrusions of the portions 6b, 6b coincides with each other. At this time, the end face of the female connector 1a and the end face of the male connector 1b are in contact with each other, and the hole of the female connector 1a and the pin of the male connector 1b face each other. Then, when the board 3 is further lowered, the female connector 1a and the male connector 1b are fitted together as shown in FIG.
When the connection is made and the final connection position is reached, both positioning guides 6
a, 6a, 6b, and 6b are disengaged. As a result, no other force acts on the connector portion, and the fitting and connection of the connector are maintained in a state where stress is not applied to the soldered portion of the connector, so that reliable electrical connection is possible. .

In the above embodiment, the connection between the boards provided with the connectors on the boards has been described. However, the present invention can be applied even when one of the connectors is not attached to the board. is there. For example, in the above embodiment, the male connector 1b may not be mounted on the board 4 but may be mounted on the case itself of the control device. In this case, the above-described positioning guide portions 6b, 6b or the positioning guide portions 6a, 6a may be formed on a connector mounting member such as a case.

[0013]

According to the present invention, there is no need to attach a special positioning jig such as a pin to a board or the like in order to fit or connect a connector, and a positioning guide portion formed at a connector mounting end of the board or the like is used. Since the board on which the connector is mounted is positioned and the connector is fitted and connected, the cost is reduced, the operation is easy, and the automation of the connector connection is facilitated. In addition, even if the allowable fitting dimensions of the connector are small, the board on which the connector is mounted is guided before the connector fitting connection, so that the fitting / connection is easy even if a general-purpose connector is used. In this case, the cost can be reduced.

Further, when the board is mounted on a case or a cover of the control device and the boards are connected by a connector mounted on the board, or one connector is mounted on a case or the like, and the other connector is mounted on the board. Even when the connector is attached to the cover, if the board is movably attached to the cover to which the board is attached by a predetermined amount, the connector is accurately fitted and connected by being guided by the positioning guide portion,
This eliminates the necessity of strictly setting the mounting position of the case and the board, thereby improving work efficiency.
