A crimping apparatus includes an anvil for supporting a metal terminal including a base plate portion for mounting an electric wire thereon and a pair of crimping piece portions extending upwardly respectively from opposite side edges of the base plate portion and a crimper which includes a groove portion being opposed to a supporting portion of the anvil. An inner surface of the groove portion of the anvil and a terminal support face of the supporting portion of the crimper cooperate to press the crimping piece portions for crimping the crimping piece portions to the electric wire mounted on the metal terminal. A width of the groove portion of the crimper is not more than 1.0 mm. The terminal support surface of the anvil is formed into a concavely curved surface in which a depth of the concavely curved surface is not smaller than 0.06 mm and is not larger than 0.17 mm in a cross-section of the anvil perpendicular to an axis direction of the electric wire.

An object of the present invention is to provide a method and an apparatus for marking an electric wire at a low cost. An apparatus 1 for marking an electric wire forms a band mark 21 on a part of an outer face 5a of the electric wire 3. The band mark 21 is formed along the entire circumference of the part of the outer face 5a of the electric wire 3. The marking apparatus 1 tightens the electric wire 3 in a state where a tensile force is applied in a longitudinal direction. The marking apparatus 1 includes a nozzle 35 for injecting coloring agent toward an uppermost position 10 of the outer face 5a of the electric wire 3. The nozzle 35 has an open end 42 which is opposed to the electric wire 3 and capable of passing the coloring agent. A straight line L extending between a center C1 of the open end 42 and a center C2 of the electric wire 3 lies along a vertical direction.

An object of this invention is to provide a connector housing which can be prevented a terminal-receiving chamber from receiving a wrong metal terminal. A connector housing 1 comprises a plurality of terminal-receiving chambers 20 and a plurality of marks 21. The terminal-receiving chamber 20 receives a male terminal 3. Electric wire 2 is attached to the male terminal 3. A mark 6 is formed on an outer surface 5a of the electric wire 2. A color of the mark 6 of one electric wire 2 is a first color R. A color of the mark 6 of the other electric wire 2 is a second color G. The first color R is different from the second color G. The mark 21 corresponds to each terminal-receiving chamber 20. A color of one mark 21 is the first color R, which is the same as the color of the mark 6 of the one electric wire 2. A color of the other mark 21 is the second color G, which is the same as the color of the mark 6 of the other electric wire 2. By forming the mark 21 in a same color as the mark 6 of the electric wire 2 attached to the male terminal 3 which is to be inserted into the terminal-receiving chamber 20 corresponding to the mark 21, the mark 21 indicates the male terminal 3 to be received by the terminal-receiving chamber 20 corresponding to the mark 21.

Disclosed are a method of and an apparatus for cleaning a plurality of nozzles of an ink jet head. This cleaning method comprises a step of covering a nozzle surface formed with the plurality of nozzles with a cap; a step of depressurizing an air space formed between the nozzle surface and the cap by use of a depressurizing element to suck the inks from the nozzles; a step of stopping the depressurization by the depressurizing element; a step of keeping the nozzle surface covered with the cap so that the inks jetted from the nozzles due to the depressurization wet-spread over the entire nozzle surface by a capillary force; and a step of retracting the cap from the nozzle surface. Further, in this cleaning apparatus, a contact angle .theta.1 between the ink and the cap internal surface and a contact angle .theta.2 between the ink and the nozzle surface are set to 90.degree. or smaller and also set such that .theta.2 is not greater than .theta.1.

A terminal crimping structure includes a terminal crimped to a copper alloy wire. The terminal has a crimping piece portion crimped to the copper alloy core wire portion. A rate of compression of the copper alloy core wire portion, of a particular diameter, by the crimping piece portion is determined from a relative relation between a parameter varying according to the ratio of (the cross-sectional area of the copper alloy core wire portion at a crimped portion)/(the cross-sectional area of the copper alloy core wire portion before crimping) and a parameter varying according to the ratio of (a cross-sectional area of an annealed copper core wire portion at a crimped portion)/the cross-sectional area of the annealed copper core wire portion before crimping) which is the rate of compression of the annealed copper core wire portion by the crimping piece portion.

A terminal crimping apparatus includes an anvil for supporting a metal terminal including a base plate portion for placing an electric wire thereon and a pair of crimping piece portions extending upwardly respectively from opposite side edges of the base plate portion and a crimper which includes a press-deforming portion having a generally arch-shape formed of two arc-shaped surfaces which are opposed to the anvil. The anvil and the crimper cooperate to press the crimping piece portions for crimping the crimping piece portions to the electric wire placed on the metal terminal. The shape of the crimper satisfies a formula, Index a=c·cos θ, where c represents a length of the arc-shaped surface of the crimper, and θ represents an angle formed by a tangential line to the arc-shaped surface at a central portion of the crimper and a vertical line.
