Description
Technical field
The utility model relates to a kind of electrician's instrument, the Press Plier that particularly a kind of house lead in connects.
Background technology
When laying-out, usually can run into the lead connectivity problem.Because it is improper that terminal connects, and tends to burn out lead, causes accidents such as fire.Statistics are arranged, and the terminal fault is occupied larger specific gravity in fire incident.Therefore, when laying-out, should avoid joint as far as possible, as the need joint, should mode according to the rules connect yet, the mechanical strength of joint should be less than 80% of lead mechanical strength; It is the same that its dielectric strength also should keep.
The method that lead connects is more, adopts which kind of method of attachment will depend on the size of using sectional area of wire, no matter and use which kind of method of attachment, the lead connection all should reach following basic demand:
(1) require the resistance of tie point little and stable;
(2) enough mechanical strengths to be arranged;
(3) wanting can be corrosion-resistant, anti-oxidant;
(4) wanting can vibration resistance.
At present, main method of attachment has the soldering conductor to connect, the machinery conductor connection etc. of colding pressing.Though copper conductor soldering connection quality is reliably, and is also uncomplicated on the technology, compares with mechanical cold-press method, it is lower to exist efficiency of construction, needs to consume non-ferrous metal tin and lead, problem such as need naked light to operate and working condition is relatively poor.Above-mentioned basic demand is then satisfied in the copper conductor cold weld easily on technical performance.And can generally not be strict with the superficial layer that forms a metal penetration by the tight purpose that reaches conduction that contacts on surface between copper and the copper, and so colding pressing, the machinery of copper conductor succeeds after soldering connects, obtained applying.
In fact up to the present the kind and the specification that are not all lead product are all selected mechanical cold weld method for use.From in 1958, the lead machinery cold weld of China, research is used through national all departments, accumulated the experience of comparative maturity, formed unified tube connector, the shape criteria of binding post and the series of products of specification, from conductor cross-section 10-400 square millimeter, the lead connection auxiliary products that arrive the 0.9-0.2 cross section again are available in all varieties, the relevant lead of the sectional area of wire 4.0-1.5 square millimeter technology that connects the kind that matches and specification and cold weld is used and is formed blank out only, the principal element that forms above-mentioned reason is the wherein regulations of the electrical safe working order (quality standard of line construction and technological requirement) issued with Electricity Department: promptly have only copper conductor to allow that using splices and twine the method for attachment rules that connect substantial connection, decades are consistent, can not adapt to the requirement of modern electric industry development and safety utilization of electric power far away.According to the current value and the safe carrying capacity of in recent years household electricity and office electricity consumption, the suitable sectional area lead of house lead in should be at the 4.0-1.5 square millimeter.Not only lead connection workload is very big for house lead in, also be the district occurred frequently of latent defect, existing house lead in is connected with the lead of service conductor, has house lead in to be connected with the lead of house lead in again, lead-connecting quality how, is with safety utilization of electric power, prevents that fire from having weighty responsibility.Because copper conductor is spliced and is twined that to connect technology simple, with low cost, is manual operations substantially, so manual operations has certain randomness, the lead-connecting quality height not only depends on level professional technology, also depend on good moral consciousness, thereby also be difficult to define quality and operation standard.Show with electrification and fire incident in a large number, allowing copper conductor to splice and twine the operational procedure that connects is in use to now, not only dragged the back leg of electric industry economic growth development, also existed the defective of technology, copper cash twines to connect and has formed oxidation, sparking, more oxidation, the more vicious circle of sparking cause when serious that lead melts short-circuit fire (this is the main cause that causes electrical fire), the basic demand that is connected with lead has a long way to go, and dielectric strength does not reach due standard yet.The performance quality of insulating barrier, the safe operation relation that connects for lead greatly the insulation level of lead connector and useful life, depend on the quality of insulating material to a great extent.For the lead connector of Miru's fishnet if will keep in repair or change insulating tape, in general be very difficult, therefore, the insulation of house lead in is a ring that the most easily gets the brush-off in the electrical safety operation, because the insulation property of insulating tape are relatively poor, peel off breakage as the shellac varnish layer, thereby cause leaking electricity, the generation of electric shock phenomenon and disaster hidden-trouble.
