Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Refer to shown in Fig. 1, the component of fingertip 2 of the invention, including fingertip 21 and some fingertips 2, described fingertip 2
1 is that 21 outer walls of tubulose and the fingertip are provided with stopper slot 53, and described fingertip 2 is circumferentially disposed along fingertip 21 and and fingertip
21 ends are slidably connected, and the described side of fingertip 2 is provided with the limited block 4 contradicted with stopper slot 53 and opposite side is provided with least one
Individual groove 5, in addition at least one ring spring 6, described ring spring 6 on each fingertip 2 with groove 5 with coordinating, conducting rod
When being inserted in the component of fingertip 2, fingertip 2 is pressed on conducting rod by spring, is matched somebody with somebody using the component internal diameter of fingertip 2 and the appropriate of conducting rod
Close, every fingertip 2 is formed two lines with conducting rod and contact, so as to obtain reliable contact.It ensure that negative on each fingertip 2
Uniformity is carried, ensure that prevents the equipment caused by phenomenon of arc discharge caused by loose contact from damaging, so as to reduce the fortune of enterprise
Seek cost.Meanwhile the pressure direction of fingertip 2 and fingertip 21 is vertical with the direction of motion, spring when contact is connected is small.Fingertip 2
With producing friction during 21 relative motions of fingertip, there is self-cleaning action.Short circuit current by when, due to fingertip 2 and fingertip 21 with
The sense of current is consistent between conducting rod, and electric power tends to fingertip 2 pressing to conducting rod, and dynamic stability is good.
The described bottom of fingertip 2 and it is provided with step trough 5, the described side wall of ladder one and fingertip close to the side of fingertip 21
21 ends be slidably connected and another side wall be provided with stopper slot 53 contradict limited block 4, by step trough 5 realize fingertip 2 with
The thickness for connecting and reducing radial direction that fingertip is 21, volume is reduced, and because glide direction is consistent with spacing direction is contradicted,
Make operation more stable, stopper slot 53 and limited block 4 coordinate the volume for not increasing the direction of motion.The described section shape of stopper slot 53
Shape is triangle, and described limited block 4 is arc convex, described limited block 4 and the linear contact lay of stopper slot 53, ensure uniformly by
