Retainer for electronic modules

A retainer for securing an electronic module to a body, the retainer comprising:

• a rail that defines an extension axis extending through a center of the rail;
• and
• a plurality of wedges arranged along the rail, the plurality of wedges being engaged with the rail to be adjustable axially and radially relative to the extension axis, to move between a first configuration and a second configuration;
• each a first wedge and a second wedge of the plurality of wedges including:
• a wedge body that defines a center axis substantially parallel to the extension axis;
• a first interlocking feature extending from a first body end of the wedge body, the first interlocking feature including:
• a distal ramp disposed axially opposite the wedge body along the center axis, the distal ramp being angled at a first angle relative to the center axis;
• and
• an inner engagement surface, disposed between the distal ramp and the wedge body, the inner engagement surface being angled at a second angle relative to the center axis, the second angle being different from the first angle;
• an adjustment device that:
• adjusts the plurality of wedges from the first configuration to the second configuration by compressing the plurality of wedges in a compression direction along the extension axis to urge the distal ramp of the first wedge against of the distal ramp of the second wedge so that the first wedge moves radially away from the extension axis in an expansion direction;
• and
• adjusts the plurality of wedges from the second configuration to the first configuration by expanding the plurality of wedges along an extension direction, opposite the compression direction, so that the inner engagement surface of the first wedge engages the inner engagement surface of the second wedge to move the first wedge one or more of:
• in the extension direction, or opposite the expansion direction.

A retainer for securing an electronic module to a body, the retainer comprising:

• a rail that defines an extension axis extending through a center of the rail;
• and
• a plurality of wedges engaged with the rail and adjustable on the rail in a compression direction, axially along the extension axis, and in an expansion direction, radially relative to the extension axis, to move from an relaxed configuration to an expanded configuration;
• a first wedge of the plurality of wedges including:
• a wedge body that defines a center axis;
• a first interlocking feature extending from a first body end of the wedge body, the first interlocking feature including a first hook having a first distal end opposite the wedge body along the center axis;
• a second interlocking feature extending from the first body end of the wedge body, the second interlocking feature including a second hook having a second distal end opposite the wedge body along the center axis;
• the first distal end being axially offset from the second distal end relative to the center axis;
• and
• the first wedge being arranged on the rail so that, as the adjacent wedge is moved in an extension direction opposite the compression direction to move the plurality of wedges from the expanded configuration to the relaxed configuration, the first and second interlocking features of the first wedge engage with interlocking features of an adjacent wedge of the plurality of wedges to urge the first wedge one or more of in the extension direction or opposite the expansion direction.
