Abstract
The utility model relates to a cable connector with a conical crimping spool, comprising a conical sleeve barrel type thread press cover and a conical crimping spool. The inner cavity of the conical sleeve barrel type thread press cover with threads is in interpenetrating conical shape, the external appearance of the interpenetrating inner cavity of the conical crimping spool is also in conical shape, and the conicity of the inner cavity of the conical crimping spool is the same with the conicity of the inner cavity of the conical sleeve barrel type thread press cover. The conical sleeve barrel type thread press cover is sheathed with the conical crimping spool to lock the wires of a cable needing to be connected. The utility model has the advantages of reasonable trend, small direct current resistance, reliable connection, high tensile strength, automatic stress adjustment among wires, small volume, compact structure and small space occupation, contact area between conducting wires and conducting wires and between conducting wires and the connectors of electrical equipment are enlarged, conductive electric current paths are increased, the temperature rise of the connecting positions of the conducting wires is less than or equals to the temperature rise of the conducting wires, insulating treatment is convenient, and failure rate is reduced. The cable connector with a conical crimping spool can be used as the cable in the field of electric network, etc.
Description
Technical field
The utility model relates to electric power system electric wire piecing devices technical field, particularly a kind of cable connector device with cone line ball pipe.
Background technology
At present, the connection of electric wire in the power network, mostly adopt the cable end of tubulose compression joint type, its lead contact-making surface carries out the transition to the crimping point from circular tube wall, sectional area of wire diminishes, contact resistance increases, crimping point local temperature is higher than the circuit temperature rise, multiple conducting wires in the same cable is when crimping, its end face all can't be accomplished at grade, be subjected to the stress influence that torsional forces forms between the lead, make a certain lead of same cable center and crimping point contact area be damaged gradually, its contact resistance is progressively increased, fashion of extrusion is mostly adopted in the tubulose compression joint type connection of electric wire one time, to its crimping position unprotect measure, because unpredictalbe external force is (as strong wind, external bump) causes rocking and spurring of cable, make the root of lead and the oxidation at crimping position accelerate greatly, this is to cause progressively one of cause of increased of contact resistance; Under the effect of electric current, because of contact resistance increases, it is the another kind of major reason that causes electric network fault that connector temperature raises, and this type of fault accounts for significant proportion (as the large area blackout of Canada and USA New York) in power grid accident, be the weak link in the electric power netting safe running.
Summary of the invention
The purpose of this utility model provides and a kind ofly can significantly increase the lead contact area, reduces a kind of cable connector device with cone line ball pipe of connecting portion resistance.
The technical scheme that its technical problem that solves the utility model adopts is: adopt cone lead line ball pipe and the telescopic union (screwed)bonnet (UB of cone (internal thread or locate screw thread) to finish being connected of electric wire in cable connecting arrangement.
Described cone line ball pipe 1 is by precentrum 2, and horizontal compressive plane 3 leaves the integrated metal structure that connects circular hole in the middle of tail cone body 4 constitutes.
The telescopic union (screwed)bonnet (UB 5 of described cone is to leave the integrated metal structure that connects part in the middle of being made of internal thread 6 cones 7, and its cone taper cooperates consistent with the cone taper of cone line ball pipe.
Its connection locking principle of the utility model is such: the telescopic internal and external screw thread gland of cone is enclosed within respectively on the cable that needs to connect, cone line ball pipe box is at the cable socket exposed part, after the Crimping Pliers extruding, cable socket exposed part and cone line ball pipe closely are connected as a single entity; Again the telescopic internal and external screw thread gland of cone is enclosed within on the cone line ball pipe,, connects locking, finish the connection of cable joint through internal and external screw thread because of its cone taper cooperates unanimity.
The beneficial effects of the utility model are: 1, the contact area of the same lead of lead, lead and electric equipment joint significantly increases, and lead conductive current road is through increasing, and trend is reasonable, and the little wire interconnecting piece megadyne temperature of D.C. resistance liter is less than or equal to the lead temperature rise; 2, connect reliably, tensile strength is adjusted stress between line greatly, automatically; 3, volume is little, through the structure compactness, simple, the position that takes up space is little, is convenient to insulation processing (as with heat-shrink tube or protecting pipe), the reliability height can significantly reduce failure rate; 4 use conventional tool, easy construction.The usefulness of the cable connection in the fields such as the utility model electric power network, power transformation, electrical equipment, motor.
Description of drawings
Among the figure: 1-cone line ball pipe, 2-precentrum, the horizontal compressive plane of 3-, 4-tail cone body, the telescopic union (screwed)bonnet (UB of 5-cone, the telescopic internal thread gland of 5-1-cone, the telescopic external screw thread gland of 5-2-cone, the 6-internal thread, the 7-cone, 8-cable, 9-cable exposure termination, the 10-bolt, 11-band counterbore line bank.
Implementation method
The utility model is described in further detail to engage accompanying drawing below.Embodiment one, cable end and power transformer porcelain vase bolt connecting mode, its operating process is such, earlier the telescopic internal thread gland of cone is enclosed within on the cable, cone line ball pipe box is flushed at the cable socket exposed part, after Crimping Pliers compresses, the more telescopic internal thread gland of cone is enclosed within on the cone line ball pipe, and is connected locking with bolt.
Embodiment two, cable and cable connected mode, its operating process is such, earlier be enclosed within the telescopic internal and external screw thread gland of cone on the cable respectively, press preceding method cone line ball pipe is clamped press fit with the cable socket exposed part respectively, the more telescopic internal and external screw thread gland of cone is enclosed within rear thread connection locking on the cone line ball pipe separately.
Embodiment three, cable and band counterbore line bank connected mode, its operating process is such: adopt external thread sleeve cartridge type gland, according to the method for embodiment one, after connecting with cable and cone line ball pipe, locking again is threaded external thread sleeve cartridge type gland with band counterbore line bank.
