摘要:
A lock includes a housing, a cable, a restrictor, and a lock unit. One end of the cable is fixed to the housing while the other end is detachably connected to the housing so as to selectively form an adjustable loop with the housing. The restrictor is rotatably disposed on the housing to selectively wedge together with the cable. The lock unit is disposed on the housing and can be selectively moved among a first position, a second position, and a third position. When the lock unit is moved toward the first position, the restrictor moves together with the lock unit to detach from the cable so as to allow the other end of the cable to disassemble from the housing. When the lock unit is moved to the second position, the restrictor restricts the cable to move toward a specific direction so as to shrink the adjustable loop. When the lock unit is moved to the third position, the restrictor wedges together with the cable, so that the length of the adjustable loop is fixed and not adjustable.

A loop connector and a cable lock having the loop connector are provided. The cable lock includes a cable, a lock body, and the loop connector. The lock body has a lock unit and a restricting unit. The lock unit can restrict or release the restricting unit to allow the restricting unit to movably restrict or release the cable. The cable thereby extends or retracts in this manner. The loop connector has a connector body that includes a first through hole and a second through hole. The first through hole and the second through hole are adjacent to each other, wherein the normal direction of the cross section of the first through hole is perpendicular to the normal direction of the cross section of the second through hole. When the cable passing through the lock body passes through the loop connector, the cable forms a plurality of loops at the lock body with the loop connector and the lock body to secure and protect one or more articles from being stolen.

An improved waveguide feed includes a ridged waveguide section and a feed section. The ridged waveguide section includes a wall structure and spaced-apart opposing ridges disposed on an internal surface of the wall structure, with the spaced-apart opposing ridges extending along a major axis of the wall structure. The feed section is coupled to the ridged waveguide section, and includes an extension of only a portion of the wall structure of the ridged waveguide section, and an extension of the spaced-apart opposing ridges disposed on an internal surface of the extended wall structure of the feed section.
