Detailed description of the invention
With reference to Fig. 1, a kind of outdoor high-voltage alternating current isolating switch contact, mainly include contact 1, fingertip spring 2, felt pad 3, fingertip is every rod 4, cross-over block 5, fingertip 6.
With reference to Fig. 2, the profile of fingertip 6 designs for warp architecture, including fixed area 12, spring region 13 and fingertip cambered surface region 14.
Fingertip 6 bends round and smooth design, and fingertip 6 when contact point C contacts with contact 1, had both ensured that the contact of conductive contact position contact point C was reliable, and added again the effect of extinguishing arc.
It is respectively equipped with transitional region between fixed area 12 and spring region 13, spring region 13 and fingertip cambered surface region 14.
With reference to Fig. 3, fixed area 12 is provided with fixing hole 15, and two symmetrical fingertips 6 are connected with conductive arm 17 through fixing hole 15 by fingertip every rod 4.Fingertip is provided with nut every the two ends of rod 4 and fixes.
Spring region 13 is provided with spring eye 16.Fingertip spring 2 is positioned by spring eye 16 with fingertip 6, and fingertip spring 2 two ends are provided with bolt and are fixed.
With reference to Fig. 4, the fingertip cambered surface region 14 of fingertip 6 is designed for cambered surface, uses point cantact mode, ensure that pressure is reliable while, achieves again flexible deciliter of contact 1, fingertip 6.
Fingertip is used for being supported in fingertip 6 every rod 4, stops to cause conductive arm to deform owing to pressure is excessive so that pressure is more stable.
Felt pad 3 it is provided with between fingertip spring 2 and fingertip 6.
Fingertip spring 2 uses external-compression type spring structure.By fingertip spring 2, two fingertips 6 are inwardly compressed.
The felt pad 3 arranged between fingertip spring 2 and fingertip 6, both ensure that contact 1 pressure was the most constant, turn avoid the situation of old-fashioned interior pulling spring spring structure spring shunting, it is to avoid because the phenomenon of spring STRESS VARIATION or ablation occurs in spring shunting.It addition, except the external-compression type spring structure of fingertip spring 2 ensures in addition to contact 1 contact pressure, fingertip 6 can rely on structure and material elasticity own to ensure contact 1 pressure, the contact pressure of the most dual guarantee contact 1.
Felt pad 3 is the electrical insulating material that a kind of elasticity, wearability, corrosion resistance, thermostability, mechanical strength, insulating properties and machining molding performance are the most excellent, is effectively come with current-carrying part fingertip 6 insulation by fingertip spring 2.
The position of spring region 13 is provided with cross-over block 5 between two fingertips 6.
Contact 1 is connected with conductive arm 17 every rod 4 by another fingertip.Fingertip is installed every the two ends of rod 4
Nut is had to fix.
Contact 1 is made up of the duplicate contact of two panels, and described contact is symmetrically installed, and is fastenedly connected by bolt 11.Described contact is to be formed by two panels copper coin bending, and surface carries out silver-plated process.Contact is symmetrically installed fastening by bolt 11, changes the Welding Structure of conventional contact, through-flow uniformly；And solving the melting welding that disconnecting switch is brought to contact due to heating effect of current, it is to avoid contact, fingertip bond, and disconnecting switch is difficult to drawing problem.
Although being disclosed this utility model by above example, but protection domain of the present utility model is not limited to this, and the equivalent under the conditions of conceiving without departing from this utility model broadly falls into protection domain of the present utility model.
