Abstract
The utility model belongs to a jointing device for an electrical source wire, which consists of an upper clip wire support, a below clip wire support, a screw and a nut. The corresponding ends of both the upper clip wire support and the below clip wire support (1, 2) are respectively provided with a corresponding relative arc-shaped grooves (1-2, 2-2) provided with a metal clip apparatus (5); the upper clip wire support and the below clip wire support as well as a clip piece (3) arranged on the outer edge of both ends are connected with each other through a guide slot (1-3, 2-3) and the screw (6) and the nut (7) of the clip piece (3) center hole, which are positioned between the upper clip wire support and the below clip wire support. The metal clip apparatus (5) arranged inside the arc-shaped groove in both corresponding ends of the upper clip wire support and the below clip wire support are connected with each other by a lead (9). The utility model has the advantages of firm and stable joint degree, much larger contact area, smaller resistance value and damage and much better sealing ability and so on. Besides, the utility model is with beautiful appearance and long life time.
Description
Technical field: the utility model belongs to the power line connecting appliance
Background technology: at present, the connection of outdoor power system line after still following traditional peelling off earlier basically and protecting and leading layer and make power lead exposed, adopts the method for twining mutually to connect again, wraps up, seals with adhesive plaster butt joint place at last.This connecting mode, because outside adhesive plaster is exposed to throughout the year, it is aging fast through the wind and weather Exposure to Sunlight, the power lead connection place easily produces oxidation corrosion, resistance increases, and electrical loss increases, the serious spark phenomenon that also can discharge, burn power line, accidents caused, cause damage.Therefore, this power line connecting mode that follows for many years, both dangerous, take electricity again, the needs that more and more uncomfortable modern power network is built.
Summary of the invention:
Technical problem to be solved in the utility model: overcome existing power line and connect its pigtail splice connection place that exists and be easy to oxidation, corrosion, big, the unsafe defective of electrical loss, a kind of safe, vacuum low-loss puncture binding clip is provided.
Its technical scheme is: binding clip of the present utility model, form by upper and lower thread tension bracket and screw rod, nut, the corresponding end of upper and lower thread tension bracket both sides offers the arc groove of the mutual correspondence of fixing metal anchor clamps respectively, upper and lower thread tension bracket and be located at its in opposite directions the intermediate plate on the outer rim of two ends connect by passing the gathering sill offered in the middle of this upper and lower thread tension bracket and screw rod, the nut of intermediate plate centre bore, be located between the metal fixture in the corresponding end arc groove of upper and lower thread tension bracket both sides and connect by lead.
Described upper and lower thread tension bracket two ends in opposite directions is circular-arc.
Described metal fixture is an arc protruding canine teeth shape metal fixture.
Be set with sheet rubber on the described metal fixture.
Described intermediate plate is circular-arc sheet metal.
Technique effect of the present utility model: because the corresponding end in upper and lower thread tension bracket both sides is fixed with the metal fixture of mutual correspondence respectively, and these anchor clamps adopt the design of arc protruding canine teeth shape, so by fastening screw rod, the nut that is connected on the upper and lower thread tension bracket, can make the upper and lower arc protruding canine teeth shape metal fixture that is fixed on the corresponding end of upper and lower thread tension bracket puncture the layer of protecting and leading on the power lead, firmly be engaged on the power lead, not only contact, and contact-making surface is big, resistance is little; Simultaneously, because the layer of protecting and leading on the power line is not stripped from, metal fixture also only is to puncture this to protect and lead layer, so protect and lead the sealing of layer to the power lead connection place, protective effect still exists, be set in sheet rubber on the metal fixture under the stressed tightening state of upper and lower thread tension bracket, form a circle sealing on layer outer rim protecting and leading of power lead connection place again, make the relative vacuum state that is in of metal fixture with interlock place of power lead, both can prevent the invasion and attack of seeking shelter from wind and rain, make interlock place be difficult for oxidation, corrosion again, so safe in utilization, the life-span is long; In addition, because circular-arc design is adopted at the two ends in opposite directions of upper and lower thread tension bracket, and be respectively equipped with the Metallic card of arcuation at these these two ends, so when fastening screw, nut, can disperse local torsion and clamping force, make upper and lower thread tension bracket and metal fixture stressed evenly, be difficult for sustaining damage or damaging.In addition, the utility model is owing to be engaged in connecting mode on the power lead after adopting metal fixture to puncture earlier to protect and lead layer, so but charging construction need not to close electric brake, and save labor, and do not influence normal electricity consumption.
The drawing explanation:
Fig. 1 is the utility model structural representation.
Execution mode: upper and lower thread tension bracket 1,2 can adopt plastic to make, this upper and lower thread tension bracket both sides corresponding end offers mutual corresponding groove 1-2, the 2-2 of arcuation respectively, be fixed with the arc protruding canine teeth shape metal fixture 5 of mutual correspondence in the groove respectively, be set with sheet rubber 4 on the metal fixture, the center of upper and lower thread tension bracket offers gathering sill 1-3,2-3, the center of circular-arc metal intermediate plate 3 offers centre bore, screw rod 6 connects with kgf nut 7 after passing gathering sill 1-3, the 2-3 of metal intermediate plate 3 and upper and lower thread tension bracket, and is fastening.Being located at has lead 9 to connect between the metal fixture 5 in upper and lower thread tension bracket 1,2 both sides corresponding end arc groove 1-2, the 2-2.
For protecting upper and lower thread tension bracket and metal fixture, intermediate plate to exempt from wind and rain and ultraviolet invasion and attack and radiation, prolong its useful life, on the outer rim of this binding clip, be provided with protective cover 8.This protective cover adopts airflow design.
