Abstract
The utility model relates to an electric connecting technology, in particular to a technology of using a cone to realize the electric connection. According to the technic proposal of the utility model, the utility model consists of an outer cone sleeve joint and an inner cone sleeve joint, besides, the interface of the inner cone sleeve and the outer cone sleeve is a taper face, an internal screw thread is arranged inside the inner cone sleeve joint that is connected with a connector with an external screw thread by using the internal screw thread, the outer cone sleeve joint is sleeved outside the inner cone sleeve joint, then which are fixed together by using a nut matched with the connector. The cone electrical connection can completely avoid the problems of point contact and line contact that exist in traditional plane electrical connection so as to realize real surface contact, thus promoting contact performance of electrical connection and reducing fault, the security and reliability of electricity transmission and operation can be ensured.
Description
Technical field
The utility model relates to electric connection technology, and specifically a kind of conical surface that utilizes is realized the technology that is electrically connected.
Background technology
Power grid enterprises are as the intermediate link in the electric power energy process of consumption, its operating electric equipment is a primary element of forming electric power system, in case break down, will cause local even regional power failure, cause enormous economic loss and bad social influence.The powerful electric power of power plant production is delivered to power consumer through facilities such as step-up substation, transmission line, stepdown substation, high-tension distributing lines.Electric equipment in these power distribution equipments and conductor, conductor and being connected of lead and electric line self or the like all be unable to do without electrical connection.
The principal mode that is electrically connected comprises that manual colligation connection, bolt connection, welding compression connect and wedge is pressed connection etc.Its principle is by contact-making surface being exerted pressure, realizing the requirement of making current.Therefore,, enough pressure-bearing surfaces must be arranged, avoid a contact to contact, form effective face contact and connect with line in order to reach the purpose of tight contact.But, existing electrical connection is owing to the reason on the structural design, in actual use, its joint has and much is in a contact and line contact condition, as shown in Figure 4, contact point by the part is providing very long current path and ampacity, and contact resistance is progressively increased, and finally causes breaking down.
Summary of the invention
The purpose of this utility model is to design a kind of conical surface electrical connector, existing some contact and line contact problems when this conical surface electrical connection can avoid traditional plane to be electrically connected fully, realize face contact truly, thereby improved the contact performance that is electrically connected, reduced the generation of fault, electric power has been carried with fail safe and the reliability moved be guaranteed.
According to design provided by the utility model, electrical connector is made up of external conical sleeve joint and inner conical drogue joint, and the contact-making surface between interior external conical sleeve is a taper surface.
In the inner conical drogue joint, internal thread is set, this screw thread of inner conical drogue connector by using with have externally threaded connector and be connected, the external conical sleeve fitting sleeve is in the outside of inner conical drogue joint, and utilization and connector nut engaged tighten together.
Described connector can be a kind of pile crown, connects ceramic storage battery in the lower end of pile crown.Connecting clamp on the external conical sleeve joint connects the wire clamp pull bar that is used for fixing lead on wire clamp.
On the external conical sleeve joint, be provided for connecting the conductor mounting hole.Connector is a bolt, on the inner conical drogue joint linking arm is set, and linking arm is connected with the outdoor AC high-voltage isolating switch.
The utility model has the advantages that: because the interior external conical sleeve connector by using conical surface interconnects, when utilizing screw element to be fastenedly connected, two cooperation conical surfaces can be more and more tightr, make whole electric face be in whole closely contact condition, thereby both contacts area have been increased, the length of electric current streamline is shortened, CURRENT DISTRIBUTION more evenly, comprehensively, reduced the contact resistance between two connectors, reduced the surface temperature between two connectors, eliminated because of accident potential such as the caused conductor joint heating of loose contact, the fail safe that has improved operation power.
Awl is connected under the effect of nut, to produce radial deformation and extruding force on the matching surface, when connector bears external applied load, matching surface is under the effect of radial compression power, all tightr than other any connected mode, thereby can greatly reduce the contact resistance in when electricity, and reduce heating, the degree of oxidation of contact-making surface to greatest extent, improve the reliability that is electrically connected.
In addition, this conical surface connected mode has reliable self-locking performance when being subjected to cross force, show superior performance when bearing this varying load of electric current, and is also more convenient when installation and removal, especially repeatedly therefore dismounting has good dismoutability to not influence of positioning accuracy.
