Because of the structural characteristics of the shape of the compression jointing clamp, conducting wires, the jointing clamp and the cover plate can be tightly pressed together; the compression jointing clamp and the cover plate are not broken off, and the compression jointing clamp with fewer specifications can cover the larger use range of conducting wires.
Description
The present invention relates to a kind of connector that the high-low voltage transmission-distribution line road connects that is used for, be commonly called as and be wire clamp, especially a kind of H-shaped crimped aluminium clip that wire clamp and lead can be pressed into one.
Connector is commonly called as wire clamp, is a kind of electric armour clamp commonly used, is divided into " tension-type wire clamp " and " non-tension-type wire clamp " two classes, and " non-tension-type wire clamp " is again for dividing " bolt lock type " and " crimp type " two kinds.
Domestic a large amount of uses at present be " parallel groove clamp " of " bolt lock type ", this kind wire clamp is to make two ducts and the bolt hole more than two or two on thick aluminium flat board, finish continuing of lead and lead with the two ditch aluminium flakes more than two or two and the pressure of nut clamping screw again, the contact area of wire clamp and lead is little, adapting electric voltage is bigger, electricity oxygen performance is unstable, so continuing of everywhere lead and lead needs to use two " parallel groove clamp ".
" H-shaped crimped aluminium clip " is made up of wire clamp matrix, duct, cover plate; and be integrally formed, and be coated with anti-oxygen protection oil that continuing as lead and lead is to use " hydraulic tongs " instrument at duct; wire clamp and lead are pressed into one; because of wire clamp and the whole closely pressing of lead, adapting electric voltage is little, and electric oxygen performance is extremely stable; so continuing of everywhere lead and lead; only need use one, and construction fast, it is best in quality to continue.
Because electric power can't store, for electric power can effectively be used, and the society need for electricity is ardent, and " power failure operation " causes the loss of the energy and the inconvenience of popular life, and " live line working " is the trend and the irresistible trend of electric utility line construction and accident maintenance from now on.
When " live line working ",, whenever have only the bolt more than two or two need use " spanner " instrument lock nut because of each place of continuing of parallel groove clamp needs to use two, constructional difficulties degree height, the constructor is easier to take place electric shock accidents.H-shaped crimped aluminium clip only need use one because of each place of continuing, and so that " hydraulic tongs " instrument crimping of insulated handle to be arranged, it is simple and easy to construct, and the constructor electric shock accidents can not take place.
In the prior art, the H-shaped crimped aluminium clip that the Taiwan Ju Ze company and the U.S. produce now all is U.S.'s specification, and is rather popular on the market at home and abroad, but this wire clamp is plate shaped cover plate, also has following shortcoming on the structure:
1. the H shape jointing clamp of existing plate shaped cover plate is U.S.'s specification, and the crimping that can not be fit to the metric system aluminum conductor of China's use fully continues.The steel-cored aluminium cable that China uses now, same nominal area because of using steel core linear diameter difference, causes the steel-cored aluminium cable diameter difference of same nominal area.So the H shape jointing clamp of existing plate shaped cover plate can't satisfy the demand that Chinese steel-cored aluminium cable crimping continues fully.At present also not at China's Aluminum lead 16～240mm
2The H shape jointing clamp of the plate shaped cover plate of design, (contain compression shape lining aluminum steel if need at the China's Aluminum lead, naked aluminium stranded conductor, steel-cored aluminium cable) the H shape jointing clamp of the plate shaped cover plate of redesign, for guaranteeing the H shape jointing clamp of same specification, the crimping minimum is to minimum, and maximum is to the lead driving fit fully of maximum, its pulling force, resistance, temperature rise can both meet international standard, then 16～240mm
2Need to use following 21 kinds of specifications to satisfy:
(1)16-25，16-25 (2)35-50，16-25 (3)35-50，35-50
(4)70-95，16-25 (5)70-95，35-50 (6)70-95，70-95
(7)120-150，16-25 (8)120-150，35-50 (9)120-150，70-95
(10)120-150，120-150 (11)185-210，16-25 (12)185-210，35-50
(13)185-210，70-95 (14)185-210，120-150 (15)185-210，185-210
(16)240-240，16-25 (17)240-240，35-50 (18)240-240，70-95
(19)240-240，120-150 (20)240-240，185-210 (21)240-240，240-240
2. though the H shape jointing clamp of existing plate shaped cover plate is U.S.'s specification, but the aluminum conductor of same specification crimping U.S. specification, when also having the aluminum conductor minimum to the crimping of minimum line footpath, because of plate shaped cover plate gos deep into duct, can't effectively fill up the duct space, cause pulling force, resistance, temperature rise etc. to be difficult to meet international standard, cause use after, the failure accident of power circuit takes place.
3. the H shape jointing clamp of existing plate shaped cover plate, same specification crimping aluminum conductor maximum are during to the max line footpath, and plate shaped cover plate just in time is covered and is connected H shape jointing clamp body two ends, forms the thin seam of two place's fragilities, and be more perishable and come off.
4. have the H shape jointing clamp of plate shaped cover plate now, because of not designing the space of cover plate extruding stopping groove, when often needing to do once above H shape jointing clamp crimping, cover plate often occurs from the crimping fracture first time, the crimping that the has a strong impact on aluminum conductor quality that continues.
5. have the H shape jointing clamp of plate shaped cover plate now, because of not designing stopping groove and safety rod in the cover plate, before conductor compression jointing, cover plate need do that 45 degree are gone up folding so that when inserting lead, toward up rolling over 90 degree, easily causes the cover plate fracture, because plate shaped cover plate does not have the design of interior stopping groove, lead is inserted duct and fold to down after the end prevents that lead from skidding off duct through last folding, breaking releasing easily consequently can't crimping.
6. above-mentioned the 5th situation, the easiest generation when live line working is because the operator hand is worn the leather glove that rubber gloves add protection; point very dumb; through regular meeting plate shaped cover plate is fractureed, so that during construction cost, especially often occur in unskilled operator.
The purpose of this invention is to provide a kind of H-shaped crimped aluminium clip that can overcome above-mentioned shortcoming, change the shape and the structure of cover plate and duct, make the packing of crimping better, the wire clamp cover plate constantly splits, thereby covers the bigger lead scope of application with the wire clamp letter of less specification.
For achieving the above object, the solution that the present invention adopts is: a kind of H-shaped crimped aluminium clip, comprise matrix, and it is characterized in that it also comprises: be located at and be connected with the matrix side and be sickle-shaped cover plate; Be located at the matrix both ends and be the duct of bomb shape; Be located at the outer stopping groove of matrix lateral surface cover plate head and matrix junction; Be located at the interior stopping groove of duct inner face outer end, cover plate head and matrix junction on the matrix; Be located at the safety rod of sickleshaped cover plate head end place projection, safety rod is parallel to outer stopping groove.
Described sickleshaped cover plate, maximum in the middle of its thickness, head takes second place, the afterbody minimum, described inside and outside stopping groove is corresponding, and is lower than the matrix outer point of wire clamp opening part, and described interior stopping groove is provided with interior corner cut near the matrix central side, and its opposite side is provided with outer salient angle.
After adopting such scheme, because the present invention has designed the duct of sickle-shaped cover plate and bomb shape, not only be better than traditional parallel groove clamp greatly, and existing compression joint type H shape wire clamp is also had tangible advantage, its concrete beneficial effect is as follows:
1. this H-shaped crimped aluminium clip, in cover plate and matrix junction, design has inside and outside stopping groove, reserves cover plate extruding space, makes the cover plate can be because of its body and conductor compression jointing, produces fracture or comes off.
