Plugger 15 moves up and down along with the motion of cam follower 27, its speed as shown in Figure 9, dead point and bottom dead centre become low speed thereon, its speed that moves up and down reaches at a high speed therebetween.

Because the beginning of crimping (or pressure) is carried out with the low-speed region of finishing all at plugger 15, therefore when crimping (or pressure), can not cut off the fine rule (core) in the lead 13.Yet, since can be between top dead-centre and bottom dead centre (or having only bottom dead centre) raising speed, so can significantly shorten the activity duration.In addition, crimping simultaneously, pressing when a plurality of also identical.

As shown in Figure 4, when making plugger 15 move left and right in this example, lead 13 is pursued root ground crimping (or pressure) each utmost point to connector, still, certainly also can make connector group 1,2 move left and right, make the utmost point of the connector that need carry out conductor compression jointing (or pressure) relative with plugger 15.

The number of poles, arrangement, the use number that constitute each connector of connector group 1,2 can be selected arbitrarily.

In illustrated example, for the speed limit that moves up and down with plugger in crimping (or pressure) operation is not damage the speed of the fine rule of lead, and used the combination of guider 18 and cam 23, cam follower 27 and cam 28, but also can use fulcrum one end in conjunction with plugger, at the other end in conjunction with following the control lever of the connecting rod of cam, make plugger move back and forth (moving up and down) thereby make cam rotation be fulcrum with the control lever as the center by connecting rod.Also can reduce the speed of plugger in crimping (or pressure) operation by the shape of selecting cam, improve the speed in other operations, shorten the activity duration.

Should be noted that: though use this speech of crimping in the claim, this speech comprises the meaning of pressing.
