Assemblies, components, and methods for creating a flameproof or explosion proof barrier

An assembly (100, 200), comprising:

• a barrier member (102) comprising:
• a first face (120);
• a second face (122);
• a peripheral edge (124) between the first face (120) and the second face (122);
• and an interior channel (126) that extends through a member depth (123) of the barrier member (102), the member depth (123) being between the first face (120) and the second face (122);
• an element having an aperture (104), the aperture (104) comprising
• a first opening (160);
• a second opening (162);
• and
• a conformal interior peripheral edge (150) between the first opening (160) and the second opening (162),
• wherein the barrier member (102) is at least partially engaged to the aperture (104), the barrier member (102) engaged to the aperture (104) by the peripheral edge (124) being at least partially conformally engaged with the conformal interior peripheral edge (150),
• wherein the barrier member (102) is at least partially composed of a material that is more malleable than a material of which the element having the aperture (104) is composed,
• wherein the second face (122) of the barrier member (102) is situated in an interior of the aperture (104),
• wherein the assembly (100, 200) is a pre-press assembly (200) that can be pressed to form an interference fit standard barrier (199).

A method for making an assembly (100, 200) having an interference fit standard barrier (199), the method comprising:

• engaging a barrier member (102) having a peripheral edge (124) with an aperture (104) having a conformal interior peripheral edge (150), wherein, when the barrier member (102) is engaged with the aperture (104), at least a portion of the peripheral edge (124) is engaged with and conformal to at least a portion of the conformal interior peripheral edge (150), wherein the barrier member (102) is at least partially but not entirely interior of the aperture (104);
• and
• applying pressure to the barrier member (102) to form the interference fit standard barrier (199) with the aperture (104), wherein elastic potential energy from the pressure applied is stored in the barrier member (102), and the elastic potential energy causes an application of force by the at least a portion of the peripheral edge (124) against the at least a portion of the conformal interior peripheral edge (150),
• wherein the interference fit standard barrier (199) complies with one or more of a flameproof barrier standard and an explosion proof barrier standard.
