Abstract
Abstract An electronic device (1) includes a set of boards (2) carrying electronic components (3). The boards are mounted so as to be separated from and parallel to one another. The electronic device (1) is capable of withstanding shocks in a defined direction approximately orthogonal to the planes of the boards (2). The electronic device (1) also includes a protective body (5) made of an elastomeric substance encapsulating the set of boards (2). The elastomeric substance fills the spaces between the boards (2) and forms at least one front shield (6), in the direction of the shocks (E) for the set of boards (2).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
124 words
An electronic device comprising a set of boards (2) carrying electronic components (3), said boards being mounted so as to be separated from and parallel to one another, said electronic device (1) being capable of withstanding shocks in a defined direction approximately orthogonal to the planes of said boards (2), which comprises a protective body (5) made of an elastomeric substance encapsulating said set of boards (2), said elastomeric substance filling the spaces between said boards (2) and forming at least one front shield (6), in the direction of the shocks (E), for said set of boards (2), said front shield (6) of said protective body (5) having a peripheral conical recess (8) intended to allow expansion of the elastomeric substance during a shock.
Claim 2
Dependent Claim
124 words
An electronic device comprising a set of boards (2) carrying electronic components (3), said boards being mounted so as to be separated from and parallel to one another, said electronic device (1) being capable of withstanding shocks in a defined direction approximately orthogonal to the planes of said boards (2), which comprises a protective body (5) made of an elastomeric substance encapsulating said set of boards (2), said elastomeric substance filling the spaces between said boards (2) and forming at least one front shield (6), in the direction of the shocks (E), for said set of boards (2), said front shield (6) of said protective body (5) having a peripheral conical recess (8) intended to allow expansion of the elastomeric substance during a shock.
Claim 3
Dependent Claim
30 words
The electronic device as claimed in claim 1, wherein said elastomeric substance forms a rear shield (7), in the direction of the shocks (E), for said set of boards (2).
Claim 4
Dependent Claim
23 words
The electronic device as claimed in claim 2, wherein said rear shield (7) of said protective body (5) has a peripheral recess (9).
Claim 5
Dependent Claim
18 words
The electronic device as claimed in claim 1, wherein said protective body (5) has a cylindrical general shape.
Claim 6
Dependent Claim
17 words
The electronic device according to claim 1, wherein said protective body (5) has a parallelepipedal general shape.
Claim 7
Dependent Claim
16 words
The electronic device as claimed in claim 1, wherein silicone is used as the elastomeric substance.
Claim 8
Dependent Claim
17 words
The electronic device as claimed in claim 1, wherein said elastomeric substance is at least partially transparent.
Claim 9
Dependent Claim
32 words
The electronic device as claimed in claim 1, which comprises at least one honeycomb auxiliary piece (13) mounted in front of the protective body (5) in the direction of the shocks (E).
Claim 10
Dependent Claim
20 words
The electronic device as claimed in claim 1, wherein said protective body (5) is surrounded by a rigid casing (10).
Claim 11
Dependent Claim
18 words
The electronic device as claimed in claim 9 wherein said rigid casing (10) is made of a composite.
Claim 12
Dependent Claim
96 words
A process for producing the electronic device (1) specified in claim 9, wherein: said set of boards (2) is inserted into said rigid casing (10) provided with openings (12) which are distributed along its longitudinal direction; the ends of said rigid casing (10) are plugged; an elastomeric substance is poured into said rigid casing (10) through said openings (12) so that said elastomeric substance encapsulates said set of boards (2) and fills the spaces between said boards (2); and said elastomeric substance solidifies, thus forming said protective body (5) and at least said front shield (6).
