Abstract

The utility model relates to a jointing clamp which is widely used in a high-voltage and low-voltage distribution circuit. The crimping quick-coupling jointing clamp comprises a substrate (1) and side pressing pieces (2), wherein the substrate is provided with two cable channels (5); the bases of two side pressing pieces (2) on two sides of the substrate (1) are connected with one flank of the substrate; the movable ends of the side pressing pieces (2) are semi-opened; and the inner cambered surfaces of the cable channels (5) are evenly provided with anti-skidding grooves (3) which are longitudinally through along the circumstance of the inner cambered surface. According to the design of the anti-skidding grooves in the cable channels, friction force between a lead and a jointing clamp is increased to further improve the electrical stability of the lead. An H-shaped jointing clamp overall tightens a coated lead after being connected with the lead by crimping instead of locally contacting the lead; current flows through an intact contact surface and is evenly distributed.

Description

A kind of compression joint type connects binding clip soon
Technical field
The utility model relates to the widely used binding clip of a kind of high and low voltage electric distribution circuit, particularly relates to a kind of compression joint type and connects binding clip soon.
Background technology
Wire clamp (or claiming electric wire connecting junction) is a kind of electric armour clamp commonly used, is widely used in wire jumper, the difference line of overhead high voltage line and low-voltage power line line pole tower, the crimping of the lead-in wire of various power equipments, service conductor, the leads such as line of entering house; Underground low-voltage aluminum power circuit hand hole connection wire, difference line, the crimping of drawing the lead of reaching the standard grade and enter house; And the non-tension lines of low pressure aluminum power circuit is intersegmental within doors, the crimping of connecting line, difference line, various power equipment low-pressure side lead-in wires etc. etc.Domestic a large amount of uses in the past be adopt the bolted mode and the plough groove type wire clamp.The shortcoming of this kind binding clip is that the contact area of wire clamp and lead is little, and CURRENT DISTRIBUTION is inhomogeneous, and it is bigger to connect resistance, and temperature rise is higher, can cause the electric energy unnecessary waste in the use, and its contact-making surface is difficult to avoid corrode and have an accident under the wind and rain invasion and attack.And, parallel groove clamp is that bolt locking and ditch aluminium flake connect lead, when live line working, because of each place of continuing needs to use 2, whenever have only the bolt more than two or two, operator needs both hands to wear rubber gloves and adds leather glove use Wrench lock nut, moves very dumb, constructional difficulties degree height, the constructor is easier to take place electric shock accidents.Be exactly that construction is inconvenient in addition.No matter which kind of bolt parallel groove clamp uses, the torsional moment that promptly is added on nut should be suitably correct, just can keep optimum continuing, but in fact the site operation peopleware is irregular, difficulty is asked suitable torsional moment, and pressure is crossed conference and caused bolt to fracture or the lead generation sex change phenomenon that continues, and the too small then contact resistance of pressure is big, temperature rise causes the failure accident that continues easily.Therefore being crimped the formula wire clamp gradually replaces.
Current normally used H molded lines anchor clamps have following distinguishing feature: 1, be one, so resistance value is little because crimping is tight, muddy, and the tight comprehensively lining lead of crimping rear sleeve, current lead-through is evenly distributed, and resistance only is several-tens micro-ohms, saves the energy.2, temperature value is low, reduces fault.Tight because of the wiring contact, resistance is little, temperature low and stretching resistance is big, can reduce failure rate more than 80%.3, be widely used.1), can be satisfied with the butt joint of the non-tension lines of various voltages (220V-hundreds of thousands volt).2), can be satisfied with (16-240mm2) various not collinearly continue through arbitrary combination.3), can be satisfied with various materials (five kinds of GB leads such as aluminium stranded conductor, copper core, aluminium core insulation line, steel reinforced aluminium conductor, copper stranded conductor).Owing to adopt high performance hydraulic tongs crimping, pressure reaches 12 tons when 4, using, reach 12 tons after hydraulic tongs automatically prompting rush down pressure, thereby reached the unified standard that continues.Avoided and bolt clamp such as ditch because of workmen's muscle power with quality is irregular differs, thereby the construction quality that is caused is uneven and the various hidden danger of generation.5,, make that construction is easy to carry, reduce stock and funds tied up because specification is few, and every kind of specification wiring span is big.The construction hydraulic tongs is an insulated handle, and the construction safety in the time of can guaranteeing live line working in particular cases like this helps on-the-spot correct construction.
Regrettably, this H molded lines folder still has some blemisies in an otherwise perfect thing: because crimping connects the grip force of the main wire clamp that relies on, and the lead groove of wire clamp and lead smoother all, frictional force is little, therefore under powerful external pull effect, might cause connection not fastening.Therefore, require further improvement its connection reliability in order fully to ensure.
The utility model content
The utility model proposes a kind of compression joint type and connects binding clip soon at the blemish in an otherwise perfect thing of existing H molded lines folder, has strengthened the frictional force between lead and the wire clamp contact-making surface, has further improved its electric stability energy.
The technical scheme that the utility model adopted:
A kind of compression joint type connects binding clip soon, comprise matrix (1), side pressure sheet (2), described matrix (1) is provided with two ducts (5), the base portion of two side pressure sheets (2) of matrix (1) both sides is connected with a flank of matrix (1), the movable end of described side pressure sheet (2) is half open configuration, is provided with the non-slip groove (3) of vertical perforation along its circumference uniform distribution at the intrados of described duct (5).
Described compression joint type connects binding clip soon, and non-slip groove (3) be arranged in parallel with the lead of the middle crimping of duct (5); Perhaps the lead of crimping has the acute angle angle in the trend of non-slip groove (3) and the duct (5).
Described compression joint type connects binding clip soon, and side pressure sheet (2) inner side end is provided with zigzag texture structure (4).
Useful good effect of the present utility model:
1, the utility model compression joint type connects binding clip soon, by the design of the non-slip groove in the duct, has increased the frictional force between lead and the wire clamp contact-making surface, has further improved its electric stability energy.H molded lines folder is tight comprehensively lining lead after crimping continues lead, and non local contact wire, electric current is passed through by complete contact-making surface, is evenly distributed, and resistance is little, temperature rise is low, fault is few, and power supply reliability is good, can reduce the power circuit energy loss, can not cause to have a power failure because of the joint accident influences the sale of electricity income, helps saving national energy.
2, the utility model compression joint type connects binding clip soon, and crimping connects fast, favourable power failure repairing, and power supply ahead of time alleviates society's injury that power outage causes, especially with traffic signals, smelting furnace, freezing and high-tech industry is the most serious.
