Description
Technical field
The utility model relates to a kind of power cable and equipment that the outlet terminal of power cable and electric equipment is connected of being used for, and relates in particular to a kind of crimp type device clamp.
Background technology
In recent years, along with deepening continuously of power grid construction and county town electric network reconstruction, power cable is able to a large amount of uses, and the demand of power equipment wire clamp increases greatly.The cable pigtail folder that now uses has following defective with electric equipment (as transformer, circuit breaker, isolating switch, wall bushing, various switch cubicle) when being connected: 1, because most equipment outlet terminals are copper coin, aluminum equipment wire clamp is connected with copper tip, the electric transition of the metal that the appearance potential difference is different, the generation couple corrosion is in operation; 2, the cable outlet wire clamp mostly is a connecting hole, crimping area deficiency, under hyperbaric environment, when outlet connects big cable, can occur overheated burn or long-term overheated lead-in wire junction oxidation until damage and crack; 3, cable outlet wire clamp pressure contact portion plane and surface pressure are not enough, cause the ampacity deficiency, and it is overheated to take place then.
Existing copper-aluminium transition equipment cable clamp be with wire clamp adopt flash of light welding, friction welding on the aluminium sheet, soldering connects or the process of copper-aluminium transition after compound, welding lastblock copper coin.The copper coin part links to each other with the copper screw bolt of electric equipment; Aluminium sheet part links to each other with aluminum lead, makes lead clamp in the online folder or simply uses aluminium or copper " nose " with the pressure of bolt.Though these two kinds of methods are available, shortcoming is more, shows a lot of limitation, mainly shows:
(1) volume is big, and the cost height is installed trouble, and the electric contact performance and the installation quality relation of wire clamp are very big;
(2) use the bolted aluminum conductor, contact area is little, and CURRENT DISTRIBUTION is inhomogeneous, and resistance is bigger, and temperature rise is higher, and useful life is short;
(3) lead and bolt contact-making surface long term exposure are in air, and the wind and rain invasion and attack are corrosion easily down, causes loosening loose contact, easily causes overheated burning out.
(4) power cable that mates relatively, the quantity not sufficient of obviously damming.
The utility model content
The technical problems to be solved in the utility model is to realize a kind of highly versatile, long service life, and also processing technology is simple, the wire clamp of convenient construction, thus the security and stability of raising device clamp guarantees power supply reliability.
To achieve these goals, the technical solution adopted in the utility model is: the special-purpose crimp type device clamp of power cable, this wire clamp is made up of conductor compression jointing pipe and connecting plate one, produce the mode that adopts the integrally casting moulding, described conductor compression jointing pipe is provided with and cooperates lead to insert and fixing cylindrical cavity, and connecting plate is provided with the installing hole that is connected with electric equipment leading-out terminal daughter board.Installing hole on the described connecting plate can doublely be symmetrical arranged or vertically open the diplopore setting.
Described installing hole quantity is more than two.
Described wire clamp respectively protrudes edges and corners is arranged to circular arc.
There is angle in bending between described conductor compression jointing pipe and the connecting plate.
Advantage of the present utility model is 1, has strengthened the contact area of lead and device clamp, has reduced resistance, has reduced loss.
2, installation is very convenient, and is quick, reduced human factor, improved efficient.
3, crimping connects and effectively to eliminate the hot stall that lead is connected with equipment, has significantly reduced the equipment that causes thus and the massive losses of power failure.
4, the copper connecting plate of arcuation has effectively been avoided point discharge phenomenon, has improved useful life.
5, the special-purpose crimp type device clamp of this power cable can guarantee that the connecting portion ampacity is greater than the power cable that matches after by the installation provision construction.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model specification and the mark among the figure are made brief description:
Fig. 1 is the wire clamp structural representation;
Fig. 2 is the side perspective of wire clamp shown in Figure 1;
Mark among the above-mentioned figure is:
1, conductor compression jointing pipe; 2, connecting plate.
Embodiment
As Fig. 1, wire clamp structural representation shown in 2 is as can be known: the special-purpose crimp type device clamp of a kind of power cable by conductor compression jointing pipe 1 and connecting plate 2 mutually amalgamation form, conductor compression jointing pipe 1 is an integral structure with 2 cast moldings of connecting plate, it is a kind of crimp type copper device clamp, wherein conductor compression jointing pipe 1 is provided with and cooperates lead to insert and fixing cylindrical cavity, connecting plate 2 is provided with the installing hole that is connected with electric equipment leading-out terminal daughter board, the position of installing hole is arranged according to the location site in hole on the electric equipment leading-out terminal daughter board of the needs connection that matches, this connecting plate 2 has increased thickness with respect to old-fashioned wire clamp, and when adopting tin plating technique or high grade requirements, connecting plate 2 surface treatments can adopt silver plating process, add zinc-plated or silver coating, the shape of connecting plate 2 can be the shape of rectangle or circular or the required cooperation of other electric equipment leading-out terminal daughter boards; All right wrap insulate overcoat outside the entire equipment wire clamp makes that exposed device clamp is not perishable and safe and reliable.This wire clamp can be widely used in the junction of equipment leading-out terminal and lead, guarantees safe and reliable power supply.
Installing hole on the connecting plate 2 is double, and to be symmetrical arranged its quantity generally be even numbers and more than two, according to being installed, needs can hole then and there or pre-set, make that like this versatility of this wire clamp is stronger, a plurality of installing holes have guaranteed that also wire clamp contacts more fully with electric equipment leading-out terminal daughter board.
The cavity of conductor compression jointing pipe 1 can use Press Plier with tight firm connection of lead and wire clamp after lead inserts, and is not only simple to operate, can also effectively increase contact area, reduces to take place the probability of hot stall.
Add man-hour connecting plate 2 and protrude edges and corners through being machined into circular shape with each of conductor compression jointing pipe 1, like this with effective point discharge phenomenon of avoiding, save manufacturing cost, improve device clamp useful life, improve the fail safe of wire clamp and power equipment, and the design of hommization like this make installation personnel can be because of sharp prism the scratch hand.
There is angle in bending between the conductor compression jointing pipe 1 of wire clamp and the connecting plate 2.According to downlead with the different of electric equipment terminal angulation are installed, generally be bent into and be divided into 30 °, 180 ° or 90 °.Copper connecting plate 2 also can increase certain thickness according to concrete cross-section of cable difference, can increase the ampacity of copper connecting plate so greatly, has improved the quality of device clamp, makes it not only can bear load current, has also left certain nargin.Simultaneously according to use occasion difference also can extend conductor compression jointing pipe 1 and connecting plate 2, increase and connect distance, strengthen the versatility of wire clamp.
