Electronic component having a resonator element arranged in an hermetically closed housing and method for manufacturing such an electronic component

An electronic component comprising at least one resonator element arranged in a first housing of a case, the case comprising:

• (a) a main part provided with a base and at least one lateral wall of annular shape;
• and
• (b) a glass cover fixed onto the main part to hermetically seal the first housing of the case, wherein at least one portion of the glass cover is transparent to a determined wavelength of a light beam to allow the resonator element to be optically adjusted, wherein the glass cover is friable or breakable,
• wherein the glass cover is fixed onto an annular rim of the lateral wall of the main part, wherein the main part is made of a hard material so that one part of the rim surrounds at least certain portions of lateral surfaces of the glass cover and ensures protection of the glass cover of the electronic component against lateral shocks, and
• wherein a height of the one part of the rim surrounding all the lateral surfaces of the glass cover is larger than or equal to a thickness of the glass cover fixed onto the rim, and wherein the one part of the rim entirely surrounds the lateral surfaces of the glass cover, and
• wherein the lateral surfaces of the glass cover comprise edges and corners, and the space provided between all the lateral surfaces of the glass cover and the one part of the rim surrounding the glass cover narrows at the corners of the glass cover.

• wherein a space is provided between the lateral surfaces of the glass cover and the one part of the rim surrounding the glass cover, wherein the space is substantially of smaller dimensions than the thickness of the glass cover in order to facilitate mounting of the glass cover on the rim of the lateral wall of the main part,
• wherein the lateral surfaces of the glass cover comprise edges and corners, and the space provided between all the lateral surfaces of the glass cover and the one part of the rim surrounding the glass cover narrows at the corners of the glass cover, and
• wherein the space is disposed to avoid propagation on the glass cover of lateral shock against the rim.
