Description
Technical field
The utility model belongs to electric cable accessories technical field, relates to the special-shaped transition joint of a kind of cable.
Background technology
110kV transition joint can be divided into conventional with three kinds of forms such as the joint between cross section joint, different cross section cable and branch joints.Conventional joint refers to the electric connecting part between same cross-sectional and electric pressure cable.Adapter body is symmetrically distributed, and is conventional cable type of attachment.There is the product of comparative maturity in domestic and international electric cable accessories producer.Cable between different cross section connects, not too common, but if any the docking between particular design or new old cable, often needs the cable intermediate joint using this form.This joint probably comprises epoxy dock; Transition joint main body two ends rubber interconnection system.
Epoxy dock is the product form of early stage Japan, install more convenient, its shortcoming is that transition joint is generally inside joint well, if water logging in rainy season, waterproof sealing generally does poorly, and cable shaft needs to increase independently automatic water pumping device for water, and water plug must be very reliable, otherwise water inlet, this joint will be in unsafe condition.Transition joint main rubber interconnection system, when the cross-section of cable is more or less the same, still easily, shortcoming because one installation when being cable butting, when the cross-section of cable differs greatly, is all difficult to realize when processing and installation this cable joint exactly.
Summary of the invention
For solving prior art Problems existing; the utility model provides a kind of cable special-shaped transition joint; this transition joint realizes being installed separately of two end cables; and sealing is integration; seal with global copper containment vessel; owing to adopting two end cable splits to install, the cross-section of cable difference at two ends can be very large, do not affect whole properties of product.
The special-shaped transition joint of the cable that the utility model provides, it is characterized in that: comprise main rubber part, described main rubber part outer wrap has copper containment vessel, draws coaxial ground line from this copper containment vessel; Be provided with cable connector chamber in described main rubber part, cable inserts from described main rubber part two ends and connects in described cable connector chamber; The inwall in described cable connector chamber is provided with high-tension shielding inserts, between described high-tension shielding inserts and cable connector cavity wall, is provided with high voltage shield; In the termination of described main rubber part, described copper containment vessel and conductive cable contacts place are provided with waterproof sealing.Coaxial ground line of the present utility model is used for ground connection, external grounding box, adopts special processes to do waterproof sealing; Copper containment vessel, both as the electrical connection of metal sheath, also plays the effect of waterproof sealing simultaneously; Main rubber part completes in plant produced together with high voltage shield, high-tension shielding inserts, and dispatch from the factory withstand voltage and local discharge test simultaneously.Ensure electric property; High-tension shielding inserts and high voltage shield composition transition joint high-tension shielding structure, high-tension shielding inserts is the silver-plated structure of aluminium alloy, ensures electric property; Waterproof sealing is used for the waterproof sealing at copper containment vessel and conductive cable contacts place.
Further, also locking device is provided with in described cable connector chamber; The core print of described cable is crimped with plug-in crimping rod, and cable is by the grafting in described cable connector chamber of plug-in crimping rod; Described locking device is for locking plug-in crimping rod.After plug-in compression rod is in place, locking device plays positioning action, and making plug-in crimp rod can not shift out, and makes cable can not throw off because cable operating temperature raises, move.
Further, described locking device is the spherical steel ball along the circumference distribution of described cable connector chamber.
Further, near the inserted terminal of described plug-in crimping rod, circumferentially on described plug-in crimping rod, offer cannelure.Spherical steel ball card realizes location in spherical groove.
Further, described waterproof sealing is waterproof insulation tape.
The special-shaped transition joint of the cable that the utility model provides can process installation respectively to two end cables, be independent of each other, plug-in is electrically connected, ensure electrical load flow, be designed with locking device simultaneously, there is spherical steel ball to lock plug crimping rod after plug crimping rod is in place, cable can not be thrown off because cable operating temperature raises mobile.After transition joint main component is installed and terminated, outside has copper containment vessel to seal, and may be dipped in safe operation in water.The utility model, by the optimal design of all parts, ensures that transition joint long-term safety is run; Can be used for the installation of the cable of different-diameter size, the cable size size at these transition joint two ends can be different.The utility model has rational in infrastructure, dependable performance, advantage easy for installation.

Embodiment
As shown in Figure 1, 2, the special-shaped transition joint of cable provided by the utility model, comprise main rubber part 3, the outer wrap of main rubber part 3 has copper containment vessel 2, draw coaxial ground line 1 from this copper containment vessel 2, copper protective layer 2 does the electrical connection of metal sheath, also plays the effect of waterproof sealing simultaneously, the external grounding box of coaxial ground line, and use special processes to do waterproof sealing; Be provided with cable connector chamber in main rubber part 3, cable inserts from the two ends of main rubber part 3 and connects in cable connector chamber; The inwall in cable connector chamber is provided with high-tension shielding inserts 5, between high-tension shielding inserts 5 and cable connector cavity wall, is provided with high voltage shield 4; High-tension shielding inserts 5 and high voltage shield 4 form the high-tension shielding structure of special-shaped transition joint, and high-tension shielding inserts adopts the silver-plated structure of aluminium alloy, ensure electric property.Main rubber part 3 is as critical component of the present utility model, complete in plant produced together with high voltage shield 4, high-tension shielding inserts 5, dispatch from the factory withstand voltage and local discharge test simultaneously, ensure electric property, main rubber part and high voltage shield, high-tension shielding inserts assembly as a whole, also simplify in-site installation program.In the termination of main rubber part 3, copper containment vessel 2 and conductive cable contacts place are provided with waterproof sealing 8, and waterproof insulation tape can be used to make waterproof sealing.For ease of the connection of cable in cable connector chamber, the core print of cable is crimped in plug-in crimping rod (cable I end plug-in crimping rod 10, cable II plug-in crimping rod 12), the cable inserted from main rubber part 3 two ends is plugged in together by plug-in crimping rod, excellent electroplate can be crimped at plug-in, strengthen flow conductivity, ensure electrically reliable connection.Throw off mobile for preventing cable because of cable operating temperature rising, be also provided with locking device 11 in cable connector chamber, this locking device pins plug-in crimping rod, plays positioning action.Locking device can realize with spherical steel ball, axially evenly installs multiple spherical steel ball clamp plug-in crimping rod in cable connector chamber; Crimping rod for making plug-in locks more firm, can at the plug end of plug-in crimping rod, and circumferentially offer cannelure, spherical steel ball card is in cannelure.
