Some examples of clamping mechanisms are: a) direct bearing screws with or wit

39、hout use of a pressure plate; b) a pressure plate or plates and a screw or screws; c) deformation of the equipment wiring terminal barrel (crimping) using a special tool; d) a spring pressure terminal; and e) an element for insulation-piercing or displacement. 6.1.4 Any rearrangement or adjustment o
