Description
Technical field
The utility model relates to electric cable fitting, particularly a kind of jockey of cable.
Background technology
In mesohigh GIS gas-insulated switchgear, circuit breaker and transformer, generally adopt inner cone socket metallic conductor and cable to carry out plug be connected, the inner cone plugging formula structure of cable and metallic conductor is good with its through-current capability, plug often, easy to install and good electric property is subject to the favor of client.
At present, for following two kinds of the more use of syndeton that inner cone cable and inner cone socket metallic conductor plug:
One is on conductor thread core, first install a taper compressing structure, and then on the outer cover of cone, a loop configuration is used for current lead-through., can there is following defect in this kind of syndeton: 1. this kind of structure needs to use special conductor crimping instrument, and does not have relevant criterion, and the equipment that each manufacturer provides is not quite similar, can not be general; 2., in onsite application process, easily come off during plug, use is brought inconvenience.
Another kind outside cable insulation, offers one hook groove, by cable conductor core with have after the loop configuration hooking groove crimps, realize the connection of cable conductor core and loop configuration in the hook groove being buckled in cable insulation and loop configuration by insulation fastener, then form the syndeton for cable and inner cone socket metallic conductor.There is following shortcoming in this syndeton: cable insulation aging or wearing and tearing after, easily cause fastener and cable insulation Joint failure, thus affect the electrical connection of cable conductor core and loop configuration; And during by external force to cable plug, also easily rupturing in the hook groove place of offering of cable insulation, causes syndeton to remain in the metallic conductor of inner cone socket, be difficult to in-situ processing.
Therefore, now need design a kind of jockey being convenient to inner cone cable plug, plug with inner cone socket metallic conductor the steadiness, convenience and the versatility that are connected to improve inner cone cable, thus realize the good electric property of electric equipment and through-current capability.
Utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, the jockey being convenient to inner cone cable plug of the simple and highly versatile of a kind of structure is provided, this jockey effectively can avoid the phenomenon of the element falling be electrically connected with cable during cable plug, thus raising inner cone cable plugs with inner cone socket metallic conductor the stability be electrically connected; Further, the electrical contact of this jockey and cable core is closely reliable, has larger through-current capability, is applicable to through-flow larger cable and uses, thus realize the good electric property of electric equipment and through-current capability.
In order to achieve the above object, the utility model is achieved by following technical proposals: a kind of jockey being convenient to inner cone cable plug, connect the conductor thread core of inner cone cable, the conductor thread core for inner cone cable is electrically connected with the plug-in of inner cone socket metallic conductor; It is characterized in that: comprise force bearing ring, compress terminal, bonding conductor and be provided with the contact ring of watch chain fingertip; Described compression terminal one end is connected with conductor thread core confined pressure, and the other end is threaded with contact ring; Described force bearing ring be set in compress terminal confined pressure be connected after conductor thread core on and be connected with cable head; Described bonding conductor is set in and compresses terminal outer and offset with force bearing ring and contact ring respectively.
In such scheme, between compression terminal of the present utility model and cable conductor core, confined pressure mode is adopted to fix, and, compress the terminal other end and be threaded with contact ring, then can realize cable conductor core and be connected with contact ring quick and facility structurally; And confined pressure mode can effectively avoid conductor thread core to crimp the problem that need be equipped with specific purpose tool, highly versatile, therefore the utility model also can realize both reliable and stable electrical connections, thus when effectively avoiding cable and inner cone socket metallic conductor to plug, the contact ring be electrically connected with inner cone socket metallic conductor holds caducous phenomenon, and then raising inner cone cable plugs with inner cone socket metallic conductor the stability be electrically connected.Simultaneously, force bearing ring plays installs the effect of locating with cable end part, bonding conductor between force bearing ring and contact ring, contact ring and force bearing ring are reliably connected with electrical contact closely reliable, and when using, force bearing ring fully contact, and has larger through-current capability with the inner cone socket metallic conductor of switch cubicle, keep equipotential, there will not be floating potential, electric discharge phenomena, thus make this jockey be applicable to the use of through-flow larger cable.
More particularly, described bonding conductor is linking springs.Linking springs also can play the same effect of bonding conductor while minimizing rapidoprint, force bearing ring is effectively connected with contact ring, thus make cable conductor and inner cone socket keep equipotential, there will not be floating potential, electric discharge phenomena are avoided to occur, and linking springs has elasticity, in use procedure, its elasticity can flexible compression and recovery, thus increases the versatility of this jockey.
