Assembly for housing wire elements

An assembly comprising at least first and second devices, each device comprising:

• a first external main face opposite a second external main face connected by a first external side face opposite a second external side face, the main faces being orthogonal to the side faces;
• a first cover;
• a second cover;
• a block including at least a semiconductor substrate, the block being in contact with the first cover and the second cover, the block separating the first cover and the second cover;
• a first electrical contact element on a first main face of the semiconductor substrate;
• a second electrical contact element connected to a second main face of the semiconductor substrate;
• a first groove in an external face of the device extending along the entire length of one of the external main faces in a direction from the first external side face to the second external side face, said first groove comprising a bottom and two sidewalls, one of the sidewalls and the bottom being formed by the first cover and the other sidewall being formed by the block, the first electrical contact element being located on the other sidewall;
• and
• a second groove in an external face of the device extending along the entire length of one of the external main faces in the direction from the first external side face to the second external side face, said second groove comprising a bottom and two side walls, one of the side walls and the bottom being formed by a second cover and the other sidewall being formed by the block, the second electrical contact element being located on the other sidewall,
• wherein a first electrically conducting wire element is embedded in one of the first and second grooves of the first device and in one the first and second grooves of the second device, the first electrically conducting wire element protruding from the first external side face of the first device and protruding from the second external side face of the second device, the first device being mobile with respect to the second device.
