A mounting assembly couples a current limiting fuse to an element that defines a longitudinal axis. The mounting assembly includes a mounting member on the element; a first attachment member coupled to the mounting member in a fixed position relative to the mounting member; and a second attachment member coupleable to the current limiting fuse. The first and second attachment members are configured to be attached to one another in a plurality of discreet positions about an axis that is non-parallel to the longitudinal axis.

Current limiting fuse

A housing for a current limiting fuse that includes a metal fuse element and a non-conductive filler material. The fuse element is configured to melt to create an open circuit when an applied current exceeds a threshold amount. The housing includes first and second cylindrical members. The first cylindrical member has an open end portion and the second cylindrical member has an integrally formed closed end portion and an open end portion configured to be attached to the open end portion of the first cylindrical member to close the housing. The housing also includes a fastening member configured to prevent the open end portion of the first cylindrical member from separating from the open end portion of the second cylindrical member when the fuse element melts.

The electrical connector of the present invention includes an electrically conductive sleeve having a passage therethrough and an elastomeric housing molded therearound. After the molding of the housing around the sleeve, a contact element is disposed within the passage of the sleeve for engagement with the contact member of another connector. An arc snuffer housing and arc snuffer are attached to one end of the contact element for guiding the contact member toward the contact element and for evolving an arc-quenching gas in response to an arc being struck between the contact member and the contact element. The contact element includes a piston member responsive to the evolved gas for jointly displacing within said passage the arc snuffer and contact element toward the contact member. A support member is provided within the sleeve for reciprocably supporting the piston member of the contact element. The piston member includes a friction surface to inhibit the movement of the piston member within the conductive sleeve until a pre-determined pressure is achieved by the arc-quenching gas and for electrically engaging the piston member with the conductive sleeve for providing electrical continuity therebetween. The support means includes a stop and a plurality of restrictions to inhibit and stop the longitudinal movement of the piston member.
