A device and method for dynamically sealing between rotatable members such as a rolling cone of a rock bit. The assembly includes a seal ring having a facing surface of a relatively hard material, such as hardened steel or tungsten carbide, and a second seal ring of a softer material, the softer material being harder, however, than typical elastomers. Suitable materials for the relatively soft seal ring include tin, copper, aluminum, magnesium, lead and alloys thereof, as well as non-metallic materials such as nylon-zytel, acetal, and polypropylene. The relatively soft seal ring may be affixed to a third seal ring or maybe affixed directly to the cone steel, for example. The seal assembly provides potential for longer life relative to elastomeric seals and requires less axial space along the journal surfaces than certain conventional metal seal assemblies.

A retention feature configured to provide interference between a threaded connection of a Luer access device and a separate device, wherein the Luer access device further comprises a septum that provides a soft interfaced between the two threadedly connected devices. The retention features of the instant invention are designed to provide the user with a tactile sensation of a tightening threaded connection, despite a soft interface between the interconnected devices. The retention features of the instant invention further prevent “spring back” and unintentional disengagement of the interconnected devices.

The invention discloses an electrical socket of an electric heating bag, which comprises a socket coupler (4), a soft isolation piece (2) and wires. The electrical socket is characterized by also comprising a plugging structural piece (8) and a fixing piece (1). The fixing piece (1) made of a hard material is in buckling connection with the soft isolation piece (2), wherein the buckling connection is realized through holes (12) and buckles (3). The socket coupler (4) is mechanically connected with the fixing piece (1). The fixing piece (1) is arranged between the socket coupler (4) and the soft isolation piece (2). The fixing piece is hard at an ordinary state so as to realize the mechanical connection of the socket coupler and the electrical socket and protect components in the electrical socket. Due to the adoption of the structure of the fixing piece (1) or the buckle edge (17), and the special structure of the soft isolation piece (2) and the buckle fin (18), the fixing piece (1) and the soft isolation piece (2) are connected reliably and firmly. The liquid leakage problem of a gap between a dry-wet soft interface opening (7) and a wire (6) is solved due to the adoption of the plugging structural piece (8).
