14A is used. That is, as shown in FIG. 5 (B), the lid member 113A is provided with a horizontally elongated concave slit 115 in the front wall portion 114A.
It is formed by forming A.

On the base end side of the lid member 113A, a concave groove 113a is formed over the entire width. This groove 1
Reference numeral 13a is a portion serving as a fulcrum when the cover member 113A is turned inside the opening 111A (see FIG. 7).

The width of the cover 113A is set slightly smaller than the width of the opening 111A. Further, the height of the lid member 113A is determined by the size of the opening 111A.
Is set to be approximately equal to the width dimension.

On the other hand, inside the bottom side of the opening 111A,
A locking portion 116A is provided for locking the lid member 113A that has been folded inward. The locking portions 116A are provided at a total of three places: a center portion and both end portions of the opening 111A.

Therefore, the lid member 113A is connected to the female body 1
At the time when 10A is formed, as shown in FIG. 5B, it is substantially flush with the front wall 114A, but before the female contact 100A is attached to the printed circuit board 300A, the opening 111A is closed. The locking portion 116

The closing of 1A is performed by pushing the lid member 113A into the inside of the opening 111A.

Further, a pair of mounting legs 117A and a pair of soldering legs 117a are provided on the bottom surface of the female body 110A. The mounting leg 117A is a portion to be inserted into a mounting hole (not shown) formed in the printed circuit board 300A. The soldering leg 117a is a portion to be inserted into a mounting hole (not shown) formed in the printed circuit board 300A. The soldered leg 117a
Is performed simultaneously with dip soldering of electronic components.

The mounting leg 117A is provided at the same position as the third contact holding hole 112A from the outside. The soldering leg 117a is provided near both ends of the female body 110A.

The other female connector 100B is exactly the same as the female connector 100A described above.

Next, as described above, one male contact 200 and two female contacts 200A, 200B
The procedure for connecting the two printed boards 300A and 300B by the inter-printed board connecting mechanism consisting of the following will be described with reference to FIGS.

The female connector 100A is connected to the printed circuit board 30.
0A, connect the female connector 100B to the printed circuit board 300B.
To each. At this time, the opening 111A is made to coincide with the substrate-side opening 330A, and the opening 111B is made to coincide with the substrate-side opening 330B. The opening 111 is formed by the mounting legs 117A and 117B and the soldered legs 117a and 117b.
A and the like coincide with the substrate side opening 330A and the like.

Dip solder is applied to the two printed boards 300A and 300B on which other electronic components are mounted. This allows not only the electronic components but also the female connectors 100A,
00B was attached to the two printed circuit boards 300A and 300B.

At the time of this dip soldering, the lid member 11
3A and 113B substantially close the openings 111A and 111B, respectively.
A does not enter the openings 111A and 111B through the openings A and 330B. Therefore, the openings 111A, 111B
There is no risk of short-circuiting the contact portions 121A and 121B of the female contacts 120A and 120B exposed inside.

Next, the two printed circuit boards 300A, 30
OB are opposed to each other at a predetermined interval. At this time, it goes without saying that one female connector 100A and the other female connector 100B face each other. The interval between the two printed boards 300A and 300B is maintained by an inter-board holder (not shown).

The male connector 200 is inserted into the opening 111A of one female connector 100A. At this time, the male contact 220 of the male connector 200 is
It is made to face the contact part 121A of 00A. Of course, the male contact 220 is made to face the contact portion 121B of the other female connector 100B.

As described above, when the male connector 200 is inserted into the opening 111A, the lid member 113A, which is locked by the locking portion 116A and substantially closes the opening 111A, is pushed away and opened. Further, when the male connector 200 is inserted, the tip of the male connector 200 is
A of the printed circuit board 300A through the substrate side opening 330A
And the printed circuit board 300B.

When the male connector 200 is further inserted from this state, the board-side opening 330 of the printed circuit board 300B is opened.
Through B, it enters into the opening 111B of the female connector 100B. At this time, the cover member 113 of the female connector 100B
B is displaced by the male connector 200.

The male contact 220 of the male connector 200 having the cover member 113B pushed away is connected to the female connector 100.
B contacts the contact portion 121B of the female contact 120B exposed inside the opening 111B. by this,
The two female connectors 100A and 100B are electrically connected by the male connector 200. As shown in FIGS. 1 and 10, the male connector 200 is inserted until the stopper 212 contacts the body 110B of the female connector 100A.

In the above-described embodiment, the connection mechanism between printed circuit boards including two female connectors 100A and 100B and one male connector 200 has been described, but the present invention is not limited to this. The connector may be composed of one female connector and one male connector.

First, a first example of such a connector will be described with reference to FIG. This connector is a female connector 100 in the connection mechanism between printed boards described above.
A, the same female connector 100C as 100B is used. That is, the female connector 100C includes a female body 100C formed of a synthetic resin having an insulating property,
It is composed of a plurality of female contacts 120C held by the female body 110C.

The opening 111C of the female connector 100C
Is provided with a lid member 113C. This lid member 11
3C closes the opening 111C on the printed circuit board 300C side. The printed circuit board 300C is provided with a substrate-side opening 330C.
The female connector 100C is attached with the opening 111C aligned with 30C.

On the other hand, as the male connector 200C, the male connector 2 in the above-described connection mechanism between printed boards is used.
In addition to the 00 type, there are a type in which one end of a printed board is formed to project in a convex shape, and a type in which a thin plate is attached to one end of a flexible substrate.

This connector connects a male contact (not shown) and a female contact 120C by inserting the male connector 200C into the opening 111C of the female connector 100C. Here, since the opening 111C is closed by the lid member 113C, when the female connector 100C is attached to the printed circuit board 300C by dip soldering, the solder does not enter the inside of the opening 111C and the female contact 120C is short-circuited. I will not let you.

A second example of such a connector will be described with reference to FIG. The female connector 100D in this connector is different from the female connectors 100A and 100B in the above-described connection mechanism between printed boards in that the opening 111D does not penetrate.
That is, the openings 111A, 11A of the female connectors 100A, 100B in the above-described connection mechanism between printed circuit boards.
Except that 1B is closed on the opposite side of the printed circuit board 300D side, the configuration is substantially the same.

The male connector 200D may be independent from the printed circuit board 300A or the like, like the male connector 200 in the above-described inter-printed-board connecting mechanism, or a part of the printed circuit board 300D may have a convex shape. It may be formed by protruding and forming. If the male connector 200D is part of a printed circuit board, the printed circuit board 300D to which the female connector 100D is attached
And the printed board on which the male connector 200D is formed is connected substantially orthogonally.

For example, as shown in FIG. 14, the present invention can be used when a plurality of sub printed circuit boards 300d are mounted on one main printed circuit board 300D. That is, the sub printed circuit board 300d is substantially perpendicular to the main printed circuit board 300D and substantially parallel to the other sub printed circuit boards 300d. Thus, a plurality of sub printed circuit boards 30
When 0d is attached to the main printed circuit board 300D, cooling air can flow between the sub printed circuit boards 300d, which is very convenient.

The female body 110D of the female connector 100D has a lid member 11 for closing the opening 111D.
3D, the female connector 100D
Does not enter the opening 111D via the board-side opening 330D at the time of dip soldering for mounting on the printed circuit board 300D.

Further, a third example of the connector will be described with reference to FIG. The opening 111E of the female connector 100E used for this connector is
The 0E side is closed. Accordingly, although there is little possibility that the solder enters the opening 111E during the dip soldering, the possibility that the solder enters the opening 111E can be remarkably reduced because the opening 111E is closed by the lid member 113E. Further, the possibility that foreign matter such as dust enters the opening 111E during storage can be significantly reduced.

With such a female connector 100E, a plurality of sub-printed circuit boards can be mounted substantially orthogonally on one main printed circuit board, similarly to the connector of the second example described above. .

[0058]

The connector according to the present invention has a female connector attached to a printed circuit board and a male connector inserted into an opening of the female connector. The male connector has an insulating property. A male body having a male body and a male contact held by the male body. The female connector has an insulating female body with the opening formed therein, and a contact portion on an inner surface of the opening. A connector having a female contact exposed and held by a female body, wherein when the male connector is inserted into the opening of the female connector, the male contact and the female contact are in contact with each other; The opening is provided with a lid member that closes the opening before inserting the male connector and opens the opening by inserting the male connector. Therefore, when the female connector is attached to the printed circuit board, the dip solder does not enter the opening, so that the female contact exposed in the opening is not short-circuited.

Further, a lid member in a state where the opening is closed is locked on the inner side surface of the opening, and the lid member is inserted through the opening.
Since the locking portion is provided with a locking portion that comes into contact with the male connector , the lid member reliably closes the opening until the male connector is inserted, thereby preventing solder from entering. In addition, foreign matter such as dust can be prevented from entering. In addition, on the base end side of the lid member,
A concave groove is formed over the entire width.

On the other hand, the connection mechanism between printed boards according to the present invention is a connection mechanism between printed boards having two female connectors and one male connector for electrically and mechanically connecting two printed boards. The female connector is provided with a lid member for closing the opening. Therefore, the female connector can be attached to the printed board at the same time as other electronic components by dip soldering without invading the solder into the opening, thereby improving work efficiency.

In addition, since this printed board connecting mechanism connects two printed boards with their soldering surfaces facing each other, the distance between the printed boards can be made smaller than that of the conventional one. That is, when the component mounting surfaces face each other, the distance between the two printed boards is determined by the height dimension of the mounted electronic component or the like. In addition, since there is no restriction on the height dimension of the electronic components and the like, the intervals can be arbitrarily determined to some extent. Therefore, the degree of freedom in designing the electronic device is improved.
