Detailed description of the invention:
Referring to Fig. 1-4, this detailed description of the invention by the following technical solutions: it comprises moving insertingSeat board 1, fingertip assembly 2 and static contact 3, fingertip assembly 2 is separately positioned on moving socket 1Both sides, moving socket 1 and static contact 3 are all positioned at the inner side of fingertip assembly 2, stationary contact3 are connected with the umbilical point contact form of high contact with every pair of fingertip.
Described fingertip assembly 2 comprises fingertip 2-1, fixed length circular shaft 2-2, disk spring2-3, securing member 2-4, pad 2-5 and position limitation bar 2-6; On fingertip 2-1, be provided withTwo bellmouth 2-1-1 and counterbore 2-1-2, fixed length circular shaft 2-2 is inserted in the right of moving socket 1Ying Kongzhong, every couple of fingertip 2-1 is separately positioned on the fixed length circular shaft 2-2 both sides on moving socket 1,The upper cover of fixed length circular shaft 2-2 that passes every pair of fingertip 2-1 outside has several pieces disk springs 2-3, fixedThe two ends of oval axle 2-2 are fastening by securing member 2-4, and the inner side of securing member 2-4 is provided withPad 2-5, the inner side at the middle part of every couple of fingertip 2-1 is provided with position limitation bar 2-6, positionThe two ends of putting limit rod 2-6 are arranged on the inside of counterbore 2-1-2. The length of position limiter certainlyInitial position and the initial contact of fingertip are determined.
In this detailed description of the invention, the installation method of multipair fingertip on moving socket is: every pair is touchedRefer to arrange at moving socket 1 both sides correspondence position, passed respectively by two fixed length circular shaft 2-2Bellmouth 2-1-1 on middle moving socket 1 on corresponding aperture and both sides fingertip outside fingertipOn side shaft, put the thick disk spring 2-3 of 0.5mm, each 5 of every side, at fixed length circular shaft 2-2 twoEnd, with 10 disk spring 2-3 on M4 fasteners compress same axis fastening, compressionAfter disk spring 2-3 make between fingertip and the ball type of contact surface of static contact to produce and initially contactPressure, and compression disk spring 2-3 can slippage on bright and clean fixed length circular shaft 2-2,The disk spring of every pair of fingertip both sides all independently compresses, and the length of fixed length circular shaft 2-2 has determined to connectTouch pressure size, the bellmouth on fingertip had both determined the position of fingertip, made again fingertip 2-1 fixedCan be to the inside on oval axle 2-2 or outer side shifting, between adjacent two couples of fingertip 2-1, there is 1mmAbove gap, non-interference, when logical super-high-current, there is good radiating condition.
In this detailed description of the invention, the length of fixed length circular shaft is fixed, at the beginning of the generation of compression disk springBeginning pressure is also definite value, also can be by M6 spacer thickness outside increase and decrease axle to initial contactDo a small amount of adjustment. The tapering that the fingertip of pressurized can be pressed bellmouth on fixed length circular shaft to the inside orA small amount of displacement is done in outside, allows moving socket to overcome initial contact shift-in static contact, moving insertingSeat board through excessive inclined-plane slippage after static contact, moving socket displacement laterally. Increase againNew contact, making the spherical before fingertip is initial value to the contact of static contactWith value added sum, every pair of fingertip can produce the contact that is greater than 14kg.
This detailed description of the invention is selected the flexible member of the high material of temperature resistant grade---disk spring,Greatly improve contact between dynamic/static contact and the stability of pressure, the contact of spherical point contactFace is more reliable, adds further at the thick silver of dynamic/static contact plated surface, therefore its overall conductive capabilityBy force, temperature rise reduces greatly.
