EXAMPLES Hereinafter, examples in which the present invention is applied to connectors for various electronic devices will be described with reference to the drawings.

First, in FIGS. 1 to 4, reference numerals 1 and 2 indicate a pair of sheet metal substrates, which are made of sheet metal such as an aluminum plate, an iron plate, or a stainless steel plate.

A large number of wiring patterns 3 and 4 to be connected to each other are printed on the opposing surfaces of both of the substrates 1 and 2.

In this printed wiring, insulating layers 5 and 6 are formed by first applying a synthetic resin adhesive or adhering a synthetic resin film to each of the opposing surfaces.

Next, conductive foils 7 and 8 such as copper foil are bonded onto each of the insulating layers 5 and 6.

Next, each conductive foil 7, 8 is etched to form a wiring pattern 3.4.

Finally, the upper resist layers 9 and 10 are removed, excluding each land portion of the wiring pattern 3.4 and the lead portions 3a and 4a for connection.
It is coated with

The printed wiring for wiring patterns 3 and 4 is printed on each sheet metal board 1.
, 2 can also be formed on the non-opposing surfaces to make a double-sided substrate; however, in this case, a single-sided substrate is shown in which it is formed only on the opposing surfaces.

By the way, a pair of locking pieces 12 are integrally provided at the end of one of the sheet metal substrates 1 with a space therebetween.

It should be noted that these circumferential body retaining pieces 12 are bent, for example, into a substantially Z-shape as shown in FIG.

A pair of locking holes 13 into which the circumferential body stopper pieces 12 are locked are formed at the end of the other sheet metal substrate 2.

Lead portions 3a and 4a of the wiring patterns 3 and 4 are drawn out in parallel between the circumferential body retaining piece 12 and the circumferential body retaining hole 13 so as to face each other from above and below.

For example, a pair of protrusions 14 are integrally provided at the end of the other sheet metal substrate 5 with a space therebetween.

Next, a pressurized conductive rubber connector 15 is used to electrically connect the lead portions 3a*4a of the wiring patterns 3 and 4.

As shown in Fig. 4, this pressurized conductive rubber connector has a conductive rubber layer 16 and a non-conductive rubber layer 11 of a thickness B thinner than the pitch A of the lead parts 3a, 4a, which are alternately adhered in a gelatinous manner. In this case, a prismatic type is used.

Reference numeral 19 denotes a positioning plate for the pressurized conductive rubber connector 15, which has a fitting hole 20 for the connector 15 and a locking hole 21 for engaging the circumferential projection 14.

According to the connector configured as described above, first, as shown in FIG.
9 is positioned by engaging with the circumferential protrusion 14 through its circumferential mating hole 21, and the pressurized conductive rubber connector 15 is fitted into the fitting hole 20 of the positioning plate 19, and this connector 15 is connected to the wiring pattern 4. It is positioned perpendicular to the lead wire 4a.

Next, as shown in FIGS. 2 and 3, one of the sheet metal substrates 1 is engaged with the circumferential body stopper hole 13 of the other sheet metal substrate 2 by the circumferential body stopper piece 12, and the entire substrates 1.2 of both plates are locked. are connected in parallel to S.

At this time, after inserting the circumferential body stopper 12 obliquely into the circumferential body retaining hole 13 from the direction of arrow C as shown in FIG. By rotating in the direction indicated by the arrow in the figure, both substrates 1 and 2 are connected in a parallel state.

In addition, in the drawing, a board bent in an fL shape is used as one of the sheet metal boards 1, but the lead parts 3a and 4a, which are the ends of both boards 1 and 2, are Both substrates 1 and 2 are in a substantially parallel state.

However, at the moment when one of the sheet metal substrates 1 is rotated in the direction indicated by the arrow in FIG.
The pressurized conductive rubber connector 15 is pressurized from above and below between both boards 1 and 2, and the lead wires 3a and 4a of the opposing wiring patterns 3 and 4 are electrically conductive under pressure. Electrical connection is ensured by the conductive rubber 16 of the conductive rubber connector 15.

At this time, as shown in FIG. 4, the peripheral protrusion 14 of the other sheet metal substrate 2 is brought into contact with one of the sheet metal substrates 1, and the entire substrate 1,
Since the gap E between the two is regulated, the maximum pressing force from above and below the pressurized conductive rubber connector 15 is always constant.
Electrical connection between the lead wires 3a*4a is ensured.

In addition, although the thickness of the positioning plate 19 is made thin in FIG. 4, if the thickness of the positioning plate 19 is configured to be the same as the thickness of the gap E, the gap E can be regulated by the positioning plate 19. I can do it.

However, the positioning plate 19 is not necessarily necessary; for example, a recess or a hole in which the pressurized conductive rubber connector 15 is fitted and positioned is provided in one of the boards 1 and 2, and the connector 15 is It is also possible to determine the position.

As described above, the connector of the present invention can mechanically connect the two boards 1 and 2 very easily without using fastening fittings such as screws, but this connector is actually used in electronic equipment. If so, both boards 1 and 2
One of them is fixed to the chassis or the like, and the free end of the other sheet metal board is fixed to the chassis or the like simply by screwing or the like.

Note that FIG. 5 shows a modified example, in which the locking piece 12 is provided on the other sheet metal substrate 2 side, the locking hole 13 is provided on the one sheet metal substrate 1 side, and these locking pieces are provided. The pieces 12 and the locking holes 13 allow the two plates 1 and 2 to be connected in the same manner as described above.

Therefore, according to the present invention, the circumferential body retaining piece 12 and the circumferential body retaining hole 13 may be provided on either side of the entire board 1, 2, or the retaining piece 12 and the retaining hole 13 may be provided on either side of both the plates 1, 2. It is also possible to separately provide one each on the substrates 1 and 2.

Further, the locking piece 12 referred to in the present invention is not limited to the S'Z shape shown in the drawings, but can be deformed into, for example, a hook shape or other various shapes.

Application Examples Although the embodiments of the present invention have been described above, the sheet metal substrate of the present invention is suitable for use as a chassis board to which various mechanical parts are attached in various electronic devices, and is also suitable for various other uses. Available for use.

Effects of the Invention As described above, the present invention not only enables the pressurized conductive rubber connector to be sandwiched between a pair of sheet metal substrates to reliably connect the wiring patterns of the pair of sheet metal substrates, but also A pair of sheet metal substrates can be mechanically coupled extremely easily without using fastening fittings such as screws.

Moreover, since each of the pair of sheet metal substrates has mechanical strength, even if a somewhat excessive force is applied to the engagement part between the locking piece and the locking hole, there is no possibility that they will be accidentally damaged. There is no problem and the reliability is high.
