DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The electronic / communication device unit structure of the present invention will now be described in detail with reference to the preferred embodiments with reference to the drawings based on the concept of the construction.

FIG. 1 shows a first embodiment of the present invention, which is UHF.
It is shown in a perspective view in a separated state as a band multiplex wireless communication device unit (hereinafter simply referred to as a device unit). In FIG. 1, the device unit 21 has a thickness of, for example, several mm.
A large number of mounting screw holes 23 are provided in a metal substrate 22 made of a flat aluminum alloy plate having a size (2 to 10 mm).

The circuit board 24, which is a printed wiring board, is attached and fixed on the metal board 22 in a close contact state by screws (not shown). A terminal block 27 to which a capacitor-type through terminal 26, which is screwed and attached to a semi-cylindrical mounting member 25 for supplying bias power near the periphery of the circuit board 24, is attached, is attached to a mounting leg 28 and a screw 2.
It is attached and fixed to the metal substrate 22 by 9.

Further, the metal housing 32 of the coaxial connector 31 for signal input / output connected to the circuit board 24 is likewise a semicylindrical shape, and is fixed to the metal board 22 by the mounting legs 33 and screws 34.

The terminal block 27 thus mounted and the metal housing 32 of the coaxial connector are electrically connected to the metal substrate 22 at the same potential.
If the metal substrate 22 is at ground potential, it will be at the same potential.

A metal lid 35 is attached from above the circuit board 24 so as to cover the circuit board 24. The metal lid 35 is a thin metal plate having a thickness of 0.4 to 1.2 mm.
It is a drawn box-shaped structural steel plate having an appropriate thickness selected from the degree, and is provided with L-shaped mounting legs 36 (only two positions on one side are shown) 36 at four peripheral positions. There is. Needless to say, it is subjected to surface treatment with good conductivity such as nickel plating for rust prevention.

Notches 38 and 39 communicating with the opening edge are formed on the side wall 37 around the metal lid 35, and the shape of one notch 38 is the fitting 2 of the terminal block.
5 corresponds to the semi-cylindrical shape, and the shape of the other notch 39 corresponds to the semi-cylindrical shape of the metal housing 32 of the coaxial connector.

In this way, the conductive rubber member 41 is arranged so as to contact the opening edge including the notch of the metal lid 35. It should be noted that, in a state where the metal lid 35 is attached to the metal substrate 22, an attachment for attaching and fixing the device unit 21 to a predetermined position such as a communication device around the outside of the metal lid 35 by applying a screw or the like. Although a hole for use is provided, it is omitted because it is complicated when illustrated. It should be understood that the same applies to each of the embodiments described below.

With the above structure, the metal lid 35 is attached to the metal substrate 22.
It is attached and fixed with four screws 42 on the top,
The circuit board 24 is entirely covered, and the conductive rubber member 41 is brought into contact with the metal fitting 32 of the semi-cylindrical attachment and the metallic housing 32 of the coaxial connector.

Such a state is a side sectional view (a) of FIG.
It is shown in (b). The figure (a) shows the positional relationship with the metal housing 32 of the coaxial connector, and the figure (b) shows the positional relationship with the mounting member 25, which are shown well in each case.

As is apparent from the drawings, the conductive rubber member 41 is conductively contacted with both the lower opening edge of the metal lid 35 and the upper surface of the metal substrate 22, and the opening edges of the notches 38 and 39. Conductive contact is made between the mounting bracket 25 and the periphery of the metal housing 32, so that electromagnetic shielding of the metal substrate 22 by the metal lid 35 is reliably achieved.

The attached state of the coaxial connector 31 is constructed so as to penetrate the side wall 37 by the notch 39 of the side wall 37 of the metal lid 35. The same applies to the terminal block 27.

FIG. 3 shows a metal lid 35 and a conductive rubber member 41.
It is a perspective view of a relationship with. In FIG. 3, the cutout 3 is representative.
9 shows only one place. The metal lid 35 is a relatively thin metal plate, which is drawn into a box shape and has side walls 37.
It has already been described that the L-shaped mounting leg 36 is attached to.

The conductive rubber member 4 is continuous with the opening edge 46 of the notch 39 communicating with the opening edge 45 around the opening.
1 are arranged so that they come into contact. The shape of the conductive rubber member shown here is shown in principle, and various modes as described later are actually applied.

A preferred state of the relationship between the metal lid 35 and the conductive rubber member 41 will be described with reference to an enlarged partial side sectional view of FIG. The opening edge 45 of the lower end opening of the side wall 37 of the metal lid 35 is formed in a curved shape 47 protruding outward in cross section.

This curved shape 47 is drawn to form an opening edge 45.
It is possible to form by means of a drawing die of a pressing device when forming, and it is not a large overhanging dimension, but is about 0.5 mm at most, and in addition to making good contact with the conductive rubber member 41. It also has a reinforcing function such that the side wall 37 is difficult to bend.

Further, the overhanging curved shape 47 is a curved surface due to the plate pressure in the lower part in the figure, but the corner angle in the upper part in the figure is bent at a right angle, which stabilizes the positioning shape and dimensional accuracy by the press die. Is being pursued.

The cross section of the conductive rubber member 41 is as shown in FIG. 5B, and the inside of the tubular shape is a cavity 48. The internal cavity 48 has an opening (slit) 49 formed in the longitudinal direction.

The material of the conductive rubber member 41 is, for example, silicone rubber, which is electrically good and has low resistance due to mixing of carbon (C). Regarding the hardness, it is relatively soft with a rubber hardness of about 30 to 50 and has a cavity 4
With the presence of No. 8, it is easy to bend and has good restorability.

When the opening edge 45 of the metal lid 35 is inserted through the opening 49 of the conductive rubber member 41 and the curved portion 47 is positioned in the hollow portion 48, it becomes as shown in FIG. In this state, the opening 49 holds the side wall 37 of the metal lid 35,
Further, since the curved portion 47 is surrounded by the hollow portion 48, the conductive rubber member 41 does not easily come off from the metal cover plate 35.

The above-described structure is the same for the cutouts 38 and 39 of the metal lid 35. By applying such a structure, one conductive rubber member 41 is formed.
The opening edges 45, 46 of the metal lid 35 continuously without interruption.
It is possible to fit along with.

This will be described with reference to the enlarged partial side sectional view of FIG. 5 in which the metal lid 35 is mounted on the metal substrate 22. As shown in FIG. 5A, the metal lid 35 is attached and fixed on the metal substrate 22 by the L-shaped attachment leg 36 and the screw 42.

In this state, the mounting leg 36 is the metal substrate 22.
The metal lid body 35 is defined by pressing it against the metal substrate 22, and the metal substrate 22 is attached to the mounting leg 36.
To the same electric potential. That is, it becomes the ground potential.

The position of the opening edge 45 of the metal lid plate 35 is set at a position spaced a predetermined distance from the surface of the metal substrate 22. This interval is nothing but the setting that the conductive rubber member 41 is compressed and contacted between the surfaces of the opening edge 45 and the metal substrate 22 with an appropriate compression amount.

The proper compression state means that the opening edge 45 is maintained in electrical contact with the metal substrate 22 and the electric shield is securely shielded during this period, and the conductive rubber member 41 is excessively large. A state in which a sufficient restoring force is maintained in the deformed shape without causing any plastic deformation.

As is apparent from the figure, the conductive rubber member 4
1 is an opening edge 45 of the metal lid 35 due to the compression deformation.
It is well shown that by closely contacting the curved shape portion 47 formed in the above, the contact area becomes a wide area without being localized and the pressing force is not concentrated.

As a result, the electrical contact resistance is reduced and the ground (earth) contact around the metal substrate 22 and the entire metal lid 35 is made stable and reliable. Good shielding and shielding.

An embodiment of the connector applied to the present invention will be described below with reference to FIG. This embodiment shows the case where the coaxial connector 31 is applied. In the coaxial connector 31, a dielectric layer (sleeve) 52 is interposed between a center conductor 51 and a metal housing 32 which is an outer conductor.

The metal housing 32 is formed by integrally forming the external connection screw at the tip, the semi-cylindrical portion and the mounting leg 33, and is made of an electrically good metal such as brass.

A conductor strip 53 is attached to the dielectric layer 52 and the central conductor 51 protruding toward the back side of the metal housing 32, and a circuit pattern (not shown) of the circuit board 24 is attached.
And the central conductor 51 are electrically connected.

As shown in FIG. 6C, the metal housing 32 is mounted and fixed to the metal substrate 22 by the mounting legs 33 and the screws 34, so that the ground potential is the same as that of the metal substrate 22. Becomes

An embodiment of the terminal block applied to the present invention will be described below with reference to FIG. Although the present embodiment shows a case where the present invention is applied to a capacitor type through terminal, such a terminal block 27 is also included in the scope of a connector for circuit connection in the present invention.

The screw-in type through terminal 26 is made of a cylindrical metal on the outside and has a thread formed on the periphery thereof. An electrically insulating layer 55 having a high dielectric constant is filled in the middle to have a capacitor function. A metal through electrode terminal 56 is provided at the center. In this way, unnecessary noise components are removed and only the necessary bias current is connected and supplied to the circuit board.

A mounting leg 28 is integrally formed with a semi-cylindrical mounting member 25 having a screw hole 57 into which the through terminal 26 is screwed, and is formed of an electrically good metal such as brass.

As shown in FIG. 1, the mounting member 25 is mounted and fixed to the metal substrate 22 by the mounting legs 28 and the screws 29, and therefore has the same ground potential as the metal substrate 22.

In the present invention, as shown in FIG. 8, the conductive rubber member 41 is connected to the flat portions 61 and 6 of the opening edge 45.
2 and four portions 63 and 64 of the cutout portions 38 and 39 may be fitted to the respective opening edges. This has the advantage that the insertion work can be performed easily.

The second embodiment of the present invention will be described with reference to the drawings. In the perspective view of FIG. 9A, a groove 67 is formed on the three peripheral surfaces of the metal housing 66 of the coaxial connector 65 in a semicylindrical shape. Similar to the previous embodiment, it has mounting legs 68 for screw fixing.

As for the terminal block, as shown in the perspective view of FIG. 7B, a groove 71 is formed on the three peripheral surfaces of a semi-cylindrical mounting bracket 69, which is the same as in the previous embodiment. Having a screw hole 72 and a mounting leg 73,
The through terminal 26 (shown in FIG. 7A) is attached to form the terminal block 74.

The coaxial connector 65 and the terminal block 74 as described above are replaced with the coaxial connector 31 and the terminal block 27 of FIG.
Instead of the above, the metal lid 35 can be reliably and easily positioned via the conductive rubber member 41. Of course, it is needless to say that the conductive rubber member 41 is set so as to fit into the grooves 67 and 71 and to be in a proper contact deformation state.

Explaining the third embodiment of the present invention, a rectangular groove 76 is formed in the metal substrate 75 as shown in the perspective view of FIG. 9B. This metal substrate 75 is similar to the metal substrate 22 of FIG.
3 is provided.

The position shape of the groove 76 corresponds to the opening edge 45 of the metal lid 35, and the coaxial connector 65 shown in FIG. 9A and the terminal block 74 shown in FIG. 7B are shown. By combining and attaching, the assembled state as shown in the side sectional views of FIGS. 10A and 10B is obtained.

FIG. 10A shows the coaxial connector 65 portion, and FIG. 10B shows the terminal block 74 portion. Further, in FIG. 5B, a portion related to the metal substrate 75 is enlarged and shown in detail. According to this embodiment, the positioning of the metal cover plate 35 with respect to the metal substrate 75 becomes more reliable.

The fourth embodiment of the present invention will be described with reference to FIG. In this embodiment, the coaxial connector 65 shown in FIG. 9A and the terminal block 74 shown in FIG. 7B are applied, but the coaxial connector 65 is omitted for convenience of explanation. It will be described with reference to FIG.

The sectional view of FIG. 11A is shown in a separated state, and the width of the groove 67 formed in the housing 66 of the coaxial connector 65 is appropriately narrower than the outer diameter of the conductive rubber member 79. . The conductive rubber member 79 of this embodiment is equivalent to the conductive rubber member 41 of the previous embodiment, but does not have a longitudinal opening (slit) as shown in the drawing. However, even if the opening is formed, the opening 6
It can be applied by directing it toward the bottom surface of 7.

Therefore, in order to insert the conductive rubber member 79 into the groove 67 as shown in FIG. 7B, the conductive rubber member 79 is pushed in based on the difference between the width and the outer diameter. As a result, the conductive rubber member 79 is compressed in the width direction and is deformed into an oval shape so as to be pressed against both side surfaces of the groove 67 and slightly increased in the height direction as shown in the figure. It is easily and securely held in 67 by frictional force.

This is because the metal housing 66
It means that it can be easily held along the curved shape around the kamaboko shape. Therefore, it is suitable to be replaced and applied as a single member like the conductive rubber members 63 and 64 of FIG.

By directly contacting the curved portion 47 of the opening edge 46 (FIG. 3) of the metal cover plate 35 from above with pressure contact.
As shown in FIG. 11C, the conductive rubber member 79
Will be elastically deformed.

Since the contact of the curved portion 47 does not locally deform compared to the contact of only the end face due to the plate thickness of the side wall 37, local stress does not act on the conductive rubber member 79, and the conductive rubber member 79 is electrically conductive. The deterioration of the elastic rubber member 79 is prevented, and the contact area is significantly widened so that good electrical contact is achieved.

The above can be applied to the terminal block 74 shown in FIG. 7B in exactly the same manner. A fifth embodiment of the present invention will be described. This embodiment is basically to use the one corresponding to the conductive rubber member 79 shown in FIG. 11A, and its mode is the conductive rubber member 61 shown in FIG.
62, 63, 64 are hollow conductive rubber members 79
It replaces with an equivalent product.

Therefore, the metal substrate is the metal substrate 75 having the groove 76 shown in FIG. 9B,
Similarly for the coaxial connector, the groove 67 of FIG.
The same applies to the coaxial connector 65 and the terminal block in which the groove 71 is formed, the terminal block 74 in which the groove 71 shown in FIG. 7B is formed.

The metal lid 35 is made of the conductive rubber 6 in the state shown in FIG.
1 to 64 are not attached to the opening edge, and the contact state is such that all parts are in the state shown in FIG. 11 (c). Therefore, the work is not required to attach the conductive rubber member to the metal lid 35, and the operation is simplified.

The curved shape 47 of the opening edge 46 is the metal lid 35.
The reinforcing effect of preventing the side wall 37 from bending in the thickness direction, the increase of the contact area, and the effect of eliminating the localized concentrated load on the conductive rubber member 79 are shown.

A sixth embodiment of the present invention will be described with reference to FIGS. 12 and 13. According to the perspective view of FIG. 12, a plurality of (two in the drawing) circuit boards 81 and 82 are attached and fixed in a close contact state on a metal board (not shown). A narrow connecting circuit board 84 for connecting a signal circuit is adhered and fixed on a metal board between the side edges of these circuit boards 81 and 82.

In this embodiment, the same coaxial connectors and terminal blocks as those of the previous embodiment are mounted and fixed to each, but they are omitted for the sake of easy understanding of the invention. There is, so please understand that way.

The metal lids 85 and 86 covering the respective circuit boards 81 and 82 are mounted on the metal board, but notches are formed in the opening edge portions of the adjacent side walls so as to avoid the connection circuit board 84 (see FIG. Then only one is visible) 8
7,87 are formed.

This portion is often shown in the enlarged partial perspective view of FIG. Between the adjoining circuit boards 81 and 82, the recess 89 is formed on the metal board 88 on both sides of the connection circuit board 84.
89 is formed, and screw holes 91, 91 are provided in the bottom thereof.

A shield plate 92 having a groove shape in a side view and a trapezoidal shape in a front view, which is fitted over the connection circuit board 84 as shown in the figure, is fitted therein, and attached and fixed by two countersunk screws 93, 93. The chevron portion of the shield plate 92 straddles the connection circuit board 84 and is provided with an appropriate interval.

A conductive rubber member 41 similar to that of the previous embodiment is fitted to the peripheral opening edge 45 of the metal lids 85 and 86 and each notch as shown in the side sectional view of FIG. By being attached, the conductive rubber member 41 is brought into contact with the metal substrate 88 and the shielding plate 92, and the electric shield is shielded without interruption. Since the detailed contents of these are the same as those already described, the description thereof is omitted here.

Also in this embodiment, the groove 76 surrounding each circuit board as shown in FIG. 9B is formed in the metal substrate, and the groove 71 shown in FIG. 7B is formed. By applying the terminal block 74 with a groove and the coaxial connector 65 with a groove 67 shown in FIG. 9A, the relationship with the conductive rubber member 79 as shown in FIG. It is possible to apply the shield shielding structure by such contact without any problem.

Needless to say, the same can be applied to the connection of a plurality of circuit boards, and the embodiment can be performed in a column or in parallel.

In the above-described embodiment, the fittings for the connector housing and the terminal block are made into a semi-cylindrical shape, but not limited to this, a trapezoidal shape, a chevron shape, and other similar shapes can be applied.

In addition, the combination of each embodiment and aspect is arbitrary, and various aspects can be applied as required.

[0084]

As described in detail above, according to the electronic / communication device unit structure of the present invention, the number of screws for mounting the metal cover plate is significantly reduced as compared with the prior art, and the number of processing steps is reduced. Assembly workability is improved.

The weight is also reduced because the cutting housing is a flat plate, and the metal lid can be a thin plate. Since it is a single plate without joints, it is possible to reduce the weight and shield the electric shield. It is a good one.

Since the basic structure can be easily standardized by standardizing the shape of the metal lid and limiting the types uniformly,
It is possible to significantly reduce the number of structural design steps. From this, a significant cost reduction can be achieved by combining with a simple structure of the metal substrate.

As for the structure, the entire circumference can be grounded and connected, so that the electric shield can be surely shielded. By bringing the circuit board into contact with the metal substrate, the heat generated during the operation is transferred to the entire metal substrate, and an efficient heat dissipation effect can be obtained.

As described above, since it has many effects, it is extremely useful when applied to this kind of field.
