Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector for mounting and connecting a plate-shaped circuit body such as a package of an IC or an LSI to another printed board or the like.

Some packages for ICs, LSIs, and the like are provided with connection pads instead of connection lead wires at the ends.

When mounting and connecting such a package to another printed board or the like, a connector as shown in FIGS. 1 and 2, for example, is used.

In this connector, a package 3 is placed on an interhousing 2 in which a large number of contacts 1 are built in so that its connection pads are in contact with the contacts 1, and a separately prepared cover 4 is placed over the package 3. .

The cover 4 is hooked at one end to one end of the housing 2, and then hooked and fastened to the housing 2 at the other end to press the package 3 against the housing 2, thereby creating contact between the contact 1 and the connecting butt. generate force.

However, in the connectors shown in Figs. 1 and 2, the housing 2 and cover 4 are deflected to a maximum at the intermediate portion between the fastening positions, resulting in a portion where the specified contact force cannot be obtained, and the electrical connection is interrupted. Becomes unstable.

In particular, as the number of cores increases and the distance between hooks on the cover becomes longer, the amount of deflection of the cover 4 and the like increases.

In addition, in the case of a pan cage that has connection lead wires that spread out horizontally from the end, whether those lead wires are connected directly to a printed circuit board etc. by soldering or inserted into a connector, there are many The work efficiency is poor because it requires bending the lead wires.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a connector for a plate-shaped circuit body that can provide a stable electrical connection and is easy to operate.

A further object of the present invention is to provide a connector for a plate-shaped circuit body that can be applied even when the plate-shaped circuit body is provided with connection lead wires at its ends.

The present invention will be explained below using examples.

FIG. 3 shows an embodiment of the connector for a plate-shaped circuit body according to the present invention.

The connector of this embodiment includes an insulating housing 11 on which a plate-shaped circuit is placed, a large number of conductive contacts 12 assembled and held in the housing 11, and a plate-shaped circuit mounted on the housing 11. It includes a cover 13 for pressing the body toward the housing 11, and an operation lever 14 for moving the cover 13 along the housing 11 and parallel to the direction in which the contacts 12 are arranged.

As can be seen from FIGS. 4 and 5, the lever 14 is rotatably engaged and attached to one end of the housing 11 by a removable structure using a lever locking spring portion 15.

This lever 14 has crank parts 17 at both ends of a rotation center shaft part 16.

The cover 13 is rotatably attached to the lever 14 by fitting the crank part 17 into a long hole 18 formed in the side plate part.

The cover 13 and lever 14 are installed by fitting the elongated hole 18 of the cover 13 into the crank part 17 of the lever 14, and then pushing the rotation center shaft part 16 of the lever 14 into the lever mounting groove 19 of the housing 11. This is done by

Now, when the cover 13 and the lever 14 are both in the upright position as shown in FIG. 13 L-shaped portions 22 contact the end surface of the housing 11 and maintain that state.

That is, in this state, the lever 14 does not rotate.

Next, after folding the cover 13 onto the housing 11 as shown in FIG. 7, the lever 14 is rotated in the direction of the arrow 23.
By rotating the crank portion 17 about the rotation center shaft portion 16, the cover 13 is moved by a distance X in the direction of the arrow 24.

During the movement of the cover 13 that moves in this manner, the plurality of lock portions 25 on the side plate portions enter below the plurality of engagement protrusions 26 on the side surface of the housing 110, thereby fixing the cover 13 to the housing 11.

Further, when the key part 25 enters below the convex part 26, it is pulled downward, and the cover 13 is lowered by a distance Y.

The cover 13 descending in this way presses the plate-shaped circuit body against the housing 11.

The state of the inner cover 13 button and lever 14 after movement is shown in the seventh figure.
It is shown by a chain line in the figure.

By the way, when the plate-shaped circuit body used is a package such as an IC or LSI having a connection pad at the end, the package is directly inserted between the pair of guides 27 and 28 at the front and rear of the housing 11. It is sufficient to set the connection pad at the end so as to come into contact with the contact 12 while inserting it.

In addition, if the plate-shaped circuit body used is a package such as an IC or LSI having a lead wire for connection at the end, as shown in FIG. A package storage case 32 of the same size is prepared, and the package 31 is fitted into the case 32 and locked with the locking protrusion 33, and at the same time, the lead wire 34 is inserted into the guide groove 3.
5 and set the package 31 assembled in the case 32 in the housing 11.

Of course, when setting the housing 11, the lead wire 34 is brought into contact with the contact 12.

After setting in the housing 11 in this manner, the cover 13 is folded down as shown in FIG. 9, and then the lever 14 is also folded down as shown in FIG. 10.

In this way, the key part 25 of the cover 13 engages with the convex part 26 of the housing 11 and pushes down the case 32, as shown in FIG.
and connect the lead wire 34 to the contact 1 as shown in FIG.
It will be understood from the explanation using FIG. 7 that the pressure contact light can be used as the pressure contact light.

Therefore, a plate-shaped circuit body such as the package 31 can be easily mounted and connected to the printed board 37 by passing the terminal portion 36 of the contact 12 through the through hole 38 of the printed board 37 and soldering.

Note that the lever 14 that has been pushed down is stopped from rotating by a lever stopper 41 provided on the side surface of the housing 11, and furthermore, is engaged with a lever lock 42 and locked.

According to such a connector for a plate-shaped circuit body of the present invention, structures for engaging the cover with the housing can be provided at several locations to prevent deflection of the cover and the housing, so that a stable electrical connection can be obtained.

Furthermore, since engagement and disengagement between them can be selected by simply moving the cover along the housing, the operation is extremely simple.

Further, there is an advantage that even if the plate-shaped circuit body has not only a connection bat but also a connection lead wire, it can be used without requiring the work of bending the lead wires.
