Embodiment
Those skilled in the art below will combine an above-mentioned accompanying drawing of mentioning and a preferred embodiment that the utility model is carried out detailed explanation and description, so that can realize or reproduce the utility model.
As shown in Figure 1, as shown in Figure 1, this embodiment provides a kind of high voltage connector 100; It includes a housing 11; Be provided with a liner 12 at these housing 11 inwalls, the bottom surface of this liner 12 is provided with a bobbin 13, and this bobbin is provided with coil (figure does not show).This bobbin 13 roughly is an I-shaped shape, and the intermediate portion has the space of a perforation, is used for holding moving iron core 14 and yoke 15.Should moving iron core 14 be one cylindric; And have first installing hole, 141, the second installing holes 142 that run through wherein, and these two installing holes communicate with each other; Wherein the diameter of this region installing hole 141 has so just formed annular end face 143 greater than the diameter of second installing hole 142 in moving iron core 14.Also have a push rod 16, the one of which end is connected in this moving iron core 14, and the other end is connected with movable contact spring 17.Between this moving contacting plate 17 and annular end face 143, have a spring 18, this spring 18 is set on this push rod 16.
Above this bobbin 13, be provided with magnetic conductor 20; The top that is positioned at this magnetic conductor 20 then is provided with an arc-extinguish chamber 30; This arc-extinguish chamber has a plane 301 and a spatial accommodation 302, the below that it is positioned at this plane 301, and being placed within this spatial accommodation 302 is magnet steel 31.Static iron core 19 is to be fixed on the coil (figure does not look).This static contact 21 is arranged on the top of movable contact spring 17, preferably directly over, conveniently to touch; From structure, this magnet steel is positioned at movable contact spring 17, the outside of static contact 21; And this static contact 21 keeps static with respect to this movable contact spring 17; This movable contact spring 17 is then because after the energising, moving iron core, the magnetic force that attracts each other between the static iron core promote this movable contact spring 17 and be in contact with one another with this static contact 21.The operation principle of high voltage connector 100 partly has explanation in background technology, and belongs to those skilled in the art and hold within knowing, and therefore repeats no more at this.Are magnet steel 31 magnetic line of force directions (the contact of active and static contact perpendicular to the contact?) the arcing direction, to play the arc extinguishing effect.On the plane 301 of arc-extinguish chamber, the position that deviates from this spatial accommodation 302 is provided with vacuum-pumping tube 32, and what be connected with vacuum-pumping tube 32 is a vacuum extractor (figure does not show); So that having increased, residing space, contact changes vacuum-pumping tube 32; Make it and exterior, use in order to vacuumize inflation, such structure can be got rid of the gas that is adsorbed on piece surface; Eliminate moisture and the solvent residue in the hole owing to decompose and evaporate, got rid of the organic gas in the organic material.To reduce or eliminate the harm of organic gas, need to prove that this vacuum-pumping tube 32 is a copper pipe preferably to contacts of contactor.And for the magnetic blow-out contactor, be that (contact is at contact?) begin to control electric arc and make it to get in the arc-extinguish chamber (whether before say arc-chute), come extinguish arcs with this.In arc-extinguish chamber, arc resistance increases, and electric current reduces, until circuit can't pilot arc, and force circuit to break off, that is to say and lean on the increase arc resistance to come blow-out.Why cry magnetic blow-out, because arc motion is to realize through electromagnetic force to arc-extinguish chamber.Get into after the arc-extinguish chamber, electric arc is divided into many serial arcs, so increased length, accelerates cooling.
More particularly, the top of this housing 11 is provided with a cover plate 40, and this vacuum-pumping tube 32 extends this cover plate 40, and a sealing cap 33 is arranged to seal this vacuum-pumping tube 32, when unnecessary, seals.Where necessary, remove sealing cap 33, make it to be connected, to realize the purpose of vacuumizing and exhausting with vacuum extractor.Around this vacuum-pumping tube 32, be provided with protruding 34 around this vacuum-pumping tube 32; This convexity 34 is arranged on the end face of cover plate 40; Preferably can be one-body molded with this cover plate, the internal diameter of its external diameter and sealing cap 33 should mate each other, to realize sealing effectiveness; Also can guarantee sealing cap 33 difficult drop-offs, add stiff stability.
Also have, this high voltage connector 100 has also comprised a bonnet 50, and this bonnet 50 is arranged on housing 11 outer walls.
The above person; Be merely wherein preferred embodiment of the utility model, can't be used for limiting the practical range of the utility model, promptly all variations of being done according to the application's claim protection range that is equal to; Replacement and modification, the institute that is all the utility model claim is contained.
