Background technology

Ring main unit is that a kind of high voltage switchgear is contained in the steel sheet metal cabinet or makes the electric equipment of assembly unit compartment ring network power supply unit, on-load switch and fuse are adopted in its core, it have simple in structure, volume is little, price is low, can improve power supply parameter and advantages such as performance and power supply safety, be widely used in the power distribution station and box-type substation of load centers such as Urban House sub-district, skyscraper, large public building, factory and enterprise.

Ring main unit generally is divided into air insulation and SF6 insulate two kinds; be used for a deciliter load current, cut-off short circuit current and no-load transformer electric current, the charging current of certain distance overhead transmission line, cable line; playing control and protective effect, is the important switchgear of ring network power supply and terminal power supply.In cabinet, the on-load switch that matches with air insulation mainly contains air-generating, air pressing type, vacuum type, and the on-load switch that matches with the SF6 insulation is the SF6 formula, because SF6 gas is enclosed in the housing, the partition fracture that it forms is invisible.

Along with coming into operation in a large number of domestic inflation ring main unit, the utilization of each manufacturer's standard unit cabinet, difficulty has appearred in the connectivity problem of standard cell and metering cabinet, if press twisted polyethylene cable to connect in adopting, then can produce the not enough situation of bending radius; If adopt flexible cord to connect, then shielding, Insulation Problems can not solve; And mostly the interface of producer's ring main unit is the internal cone type interface, must make and adopt other form annexes to connect again after special crossover sub is drawn high pressure, and connecting link increases, and installs comparatively loaded down with trivial detailsly, has reduced production efficiency, the also corresponding raising of production cost.

The utility model content

The purpose of this utility model is to solve the problems of the prior art, provide a kind of quick and easy for installation, shield effectiveness good and can satisfy the flexible cable jockey of the inner cone size of different manufacturers.

The technical solution of the utility model is: a kind of flexible cable jockey, described jockey comprises connection-peg, cable and cable termination, described connection-peg is three-layer co-extruded all insulation, full-shield, hermetic plug-in type connection-peg, fixedly connected by screw thread crimping mode between the cable core of described connection-peg and cable one end, described cable holds integral type to be connected in described cable termination in addition.

Preferably, the two ends of described connection-peg are the plug-in type connection-peg of taper, are provided with staggered a plurality of first fixing threaded hole in a side of connection-peg.

Preferably, described connection-peg circumferentially is set with pressing plate, and described pressing plate is provided with second fixing threaded hole that is used for fixing described connection-peg.

Preferably, described cable is middle pressure rubber-covered shielded flexible cable.

Preferably, described cable termination is the umbrella shape terminal of full-shield.

Preferably, described cable termination is separable connector, adopts the terminal or the totally enclosed plug connector of open type to be electrically connected, joint and PT plug before and after comprising.

The beneficial effects of the utility model are: adopt integral structure directly connection-peg to be connected with cable with cable termination, need not the intermediate conversion parts, connection-peg adopts three-layer co-extruded technology manufacturing, electric property is more excellent, be electrically connected with the cabinet socket and adopt the fingertip structure, one slotting getting final product, convenient and swift, and connection-peg is connected with cable and adopts screw thread crimping mode to connect, need not special-purpose crimping tool, and time saving and energy saving, through-current capability is good, meet complete machine temperature rise requirement, have detachable, removable function, connection-peg structure advanced person, have good insulation performance and shielding action, intermediate cable adopts the rubber-covered shielded type cable, and bending radius is little, the connection between being convenient between the ring main unit cabinet.

Description of drawings
