Abstract
Separation device assemblies include a first plate defining respective contact surfaces and engagement surfaces and a second plate defining a respective contact surfaces and engagement surfaces. A fracture groove is located on separation walls of the first and second plates. A first end member, a second end member, and the separation wall of the first plate define a first plate expansion device channel and the second plate defines a similar second plate expansion device channel. When assembled, the first plate and the second plate form an expansion device cavity and the first and second plates form a frangible joint. The respective engagement surfaces are configured to engage with receiving channels of attachable mounting devices.
Claims18
A separation device assembly comprising:
- a first plate having a first end member, a second end member, and a separation wall extending between the first end member and the second end member with a fracture groove located proximate the first end member, the first end member and the second end member each defining a respective contact surface and a respective engagement surface, wherein the contact surface of the second end member comprises a positioning member groove configured to receive a portion of at least one of a positioning member or a retaining member;
- a second plate having a first end member, a second end member, and a separation wall extending between the first end member and the second end member with a fracture groove located proximate the first end member, the first end member and the second end member each defining a respective contact surface and a respective engagement surface, wherein the contact surface of the second end member comprises a positioning member groove configured to receive a portion of the at least one of the positioning member or the retaining member;
- and
- wherein the first end member, the second end member, and the separation wall of the first plate define a first plate expansion device channel and the first end member, the second end member, and the separation wall of the second plate define a second plate expansion device channel,
- wherein, when the respective contact surfaces of the first and second end members of the first plate contact the respective contact surfaces of the first and second end members of the second plate, the expansion device channels of the first and second plates form an expansion device cavity in which an expansion device is disposed,
- wherein, when the respective contact surfaces of the first and second end members of the first and second plates are joined, the first and second plates form a frangible joint;
- wherein the respective engagement surfaces are configured to engage with receiving channels of attachable mounting devices;
- and
- wherein the positioning member or the retaining member supports the expansion device off-centered to a side of the expansion device cavity.
