The conductive connector for high voltage electrical equipment that the present invention proposes; comprise contact base, be fixedly arranged on the fingertip of described contact base and contact cover; contact overlaps one end and is fixedly arranged on described contact base periphery; one end away from contact base is provided with in annular and turns edge; inside turn edge higher than described fingertip, on turning edge in annular, be installed with high temperature resistant guard ring.Contact cover is sheathed on contact base and exceeds fingertip end; electric fields uniform can be made; outside high temperature resistant guard ring is located in annular and is turned edge; the burning position due to the electric arc produced in corresponding contact head and fingertip swapping process can be shifted; avoid the contact conducting surface in arc erosion fingertip, thus improve breaking capacity and the life-span of Elecrical connector.
Fingertip one end is fixedly arranged on contact base, the other end deviates from contact base and overhangs into free end, the fingertip of described annular distribution is provided with groove on the outer shroud side face near free end side, described groove distributes circlewise, in groove, be provided with the endless elastomeric applying radial contracting forces to each fingertip, make fingertip and corresponding contact end in contact reliable; Fingertip and contact base are wholely set, and conductive connector structure is simple, are easy to assembling and use.The inner surface of all fingertips surrounds an indent cylinder, all fingertips surround a hollow cylinder, described indent cylinder and corresponding contact end in contact are electrically connected, fingertip is easy to processing, by elastomeric lock ring, fingertip axially all can be conducted electricity with corresponding contact end in contact within the scope of certain length, enlarge active surface, improve conduction switching performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1;
Fig. 2 be in Fig. 1 fingertip and contact base coordinate schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2; a kind of embodiment of conductive connector for high voltage electrical equipment; comprise contact body 1; contact body comprises contact base 1-2 and at least two the ring-shaped distributed fingertip 1-1 be wholely set; fingertip 1-1 one end is fixedly arranged on contact base 1-2; the other end deviates from contact base 1-2 and overhangs into free end; contact base excircle is welded with the contact cover 2 of hollow barrel-type; one end that contact cover 2 exceeds fingertip 1-1 free end is provided with in annular and turns edge, and is welded with high temperature resistant guard ring 4 in annular on turning edge.
Hollow circular cylinder is processed at least two elongate slot 1-3, fingertip 1-1 is formed between adjacent two elongate slot 1-3, therefore each fingertip 1-1 distributes in the form of a ring, each fingertip inner concave is a conducting surface, contact with corresponding contact jaw and be electrically connected, the excircle of the fingertip 1-1 of annular spread is provided with groove 1-4 near free end side, therefore groove 1-4 distributes and forms annular, spring 3 is provided with in described groove 1-4, described spring 3 is when free state, its internal diameter is less than the external diameter of groove 1-4, spring 3 makes fingertip 1-1 produce predeformation, contact is formed when the grafting of corresponding contact end enters Elecrical connector and between each fingertip 1-1 indent cylinder, ensure fingertip 1-1 axially in certain length and corresponding contact end reliable contacts, improve contact area, improve conduction connectivity.Fingertip free end is cambered surface 1-5, when corresponding contact end and fingertip electrical contact, has good guide effect to contact jaw.
In conduction connection procedure; when corresponding contact end by high temperature resistant guard ring 4 and contact overlap the opening part turned edge in 2 annulars enter contact body 1 to contact with fingertip 1-1 be electrically connected time; contact cover 2 makes conducting surface internal electric field even; the radially convergent force that endless elastomeric 3 couples of fingertip 1-1 apply makes the contact force of corresponding contact end and fingertip 1-1 increase; improve the electrical connectivity of fingertip 1-1 and corresponding contact end, improve conductive capability.When contact jaw is extracted; when contact jaw and fingertip 1-1 disconnect; electric arc can be produced; high temperature resistant guard ring 4 is welded with on turning edge in the annular exceeding fingertip 1-1; the burning position of electric arc can be made to shift; avoid electric arc to the ablation of fingertip 1-1 conducting surface, protection Elecrical connector is not damaged, and improves breaking capacity and life-span that conduction connects machine.
In other embodiments of the invention, fingertip 1-1 can also be square ring or straight-flanked ring distribution, then makes the groove on fingertip outer wall also in corresponding annular distribution.
What endless elastomeric adopted in the present invention is spring, can also adopt steel ring in other embodiments.
Contact cover is fixed on contact base by the mode of welding in the present invention, and the mode of screw connection or rivet interlacement can also be adopted in other embodiments to realize.
In the present invention high temperature resistant guard ring be adopt welding manner to be fixed on contact cover opening part annular in turn edge on, screw can also be adopted in other embodiments to connect or on the mode of rivet interlacement is fixed in described annular and turns edge.
