Optical fiber assembly and connection structure of optical fiber assembly and electronic device

An optical fiber assembly comprising:

• a circuit board including a first face and a second face on the opposite side to the first face, the first face having first and second regions being different regions from each other, and the second face having a third region on the opposite side to the first region and a fourth region on the opposite side to the second region;
• a converter being an opto-electronic or electro-optic converter on the first region of the circuit board;
• an optical fiber including a first portion being a leading end portion of the optical fiber, the first portion being optically connected to the converter;
• a circuit on the first region of the circuit board, the circuit being electrically connected to the converter;
• an external connecting part on the fourth region of the circuit board;
• a pressable part fixed directly or indirectly to the circuit board such as to be positioned on the second region of the circuit board without contacting the converter, the optical fiber, or the circuit;
• and
• a cover having electrical conductivity, wherein the circuit board further includes:
• a first mounting portion on one side of a first direction of the circuit board, the first direction extending substantially parallel to the first face of the circuit board, and
• a second mounting portion on the other side of the first direction relative to the first mounting portion and the first region of the circuit board,
• the cover includes:
• a cover body covering the first and second regions of the first face of the circuit board, the converter, the first portion of the optical fiber, and the circuit,
• a first attachment portion fixed directly or indirectly to the first mounting portion of the circuit board, and
• a second attachment portion fixed directly or indirectly to the second mounting portion of the circuit board, and
• the pressable part is constituted by a portion of the cover body that is located over the second region, and the second attachment portion,
• the second direction intersects the first direction, and the third direction is substantially orthogonal to the first and second directions and includes one and the other sides of the third direction, and
• the first attachment portion includes:
• a hook generally of L-shape in side view, the hook extending from the cover body toward the circuit board and being in contact with faces of the first mounting portion of the circuit board on the one side of the first direction and on the other side of the third direction, and
• an abutment extending from the cover body toward the circuit board and being in contact with a face of the first mounting portion on the one side of the third direction, without contacting the converter, the optical fiber, or the circuit.
