Abstract: A female connector comprises an insulating body having a socket inside and a rib positioned along a long direction of the socket. A gap is formed on the socket opposite to that rib, and a slot is positioned under the gap. A plurality of electrical leads protrude out of the insulating body. A metal housing enclosing the insulating body has a discontinuous portion. The discontinuous portion has a latch disposed on a first end of the discontinuous portion and a wing extending and inwardly hooking from a second end of said discontinuous portion. The latch is inserted into and engages with the slot.

Abstract: A liquid filter comprising a casing having a feed pipe, at least a drain pipe and at least a flushing pipe respectively fastened at different level positions, at least a circular filter and at least a rotary wire brush device. Feeding liquid which is pumped through the feed pipe along the inner wall into the casing is induced by the drain pipe and stirred by the wire brush device to rotate inside the casing permitting the mid-stream of the rotating liquid to penetrate through the circular filter. The filter has a smooth, elastic, convex outer surface which prevents fibrous or other debris from attaching thereto, form mid-stream osmosis filtration effect under straining rotation fluid at constant flowing pressure.
