Here, the angle a2 refers to a correction angle. - Next, the
second press bar 700 will be described. As shown inFIG. 4 or6 , thesecond press bar 700 may be provided on the rear surface of thebody housing 100 to be movable forwards or backwards by the cylinder or the like, thus pressing the rear-endvertical portion 15 supported by thesecond angle adjuster 600 and thereby forming the corrected angle a2 between the firsthorizontal portion 11 and the rear-endvertical portion 15, as shown inFIG. 12E . - Next, the
press block 800 will be described. As shown inFIG. 4 or5 , thepress block 800 is provided above thebody housing 100 to press the firsthorizontal portion 11 and thereby fix the terminal 10. - Next, the

As shown inFIG. 4 or11 , thepress hook pin 1000 is a component which is rotatably formed on a front surface of thepress block 800 to press the front-endvertical portion 12 by pressing thethird press bar 900 and thereby have an angle a3 between the firsthorizontal portion 11 and the front-endvertical portion 12, and is composed of ahinge portion 1010, acircular head 1020, and apress protrusion 1030. Here, the angle a3 refers to a correction angle. - The
hinge portion 1010 is a component which is hinged to thepress block 800 to allow thepress hook pin 1000 to be rotatably connected to thepress block 800. - The
circular head 1020 is a circular component which is formed above thehinge portion 1010 to be positioned between thethird adjusting screw 1110 and thethird press bar 900, and guides thepress hook pin 1000 to smoothly lie forwards or backwards about thehinge portion 1010 by manipulating thethird angle adjuster 1100 which will be described later. - The
press protrusion 1030 is a ring-shaped component which is formed under thehinge portion 1010 to protrude inwards from thebody housing 100, and may directly strike the front-endvertical portion 12 by pressing thethird press bar 900 to form the correction angle a3 as shown inFIG. 12E . - Next, the
third angle adjuster 1100 will be described. As shown inFIG. 4 or11 , thethird angle adjuster 1100 is a component which is provided on the front surface of thebody housing 100 to be moved forwards and backwards by a worker's manipulation and thereby adjust the angle of thepress hook pin 1000, and is composed of athird adjusting screw 1110 and anelastic member 1120. - The
third adjusting screw 1110 is a component which is formed on the front surface of thebody housing 100 to move forwards or backwards depending on the rotating direction, and has a curved surface on a portion coming into contact with thepress hook pin 1000. As the third adjusting screw is moved forwards or backwards by theelastic member 1120 which will be described later, thepress hook pin 1000 may lie forwards or backwards or may be kept vertical. - The
elastic member 1120 is a component which is provided between the lower portion of thethird adjusting screw 1110 and thepress hook pin 1000 to provide an elastic force to thepress hook pin 1000. When thethird adjusting screw 1110 moves backwards, the elastic member becomes in a tension state, thus maintaining a state in which thepress hook pin 1000 lies backwards. When thethird adjusting screw 1110 moves forwards, the elastic member becomes in a compressed state, thus maintaining a state in which thepress hook pin 1000 lies forwards. -
