Abstract
The invention discloses a copper aluminium wire transition crimping clamp comprising a tubular clamp body and a forcing screw arranged on the clamp body, wherein the forcing screw is connected with the clamp body by virtue of a screwed hole, and the end part of the forcing screw is provided with a blanking plate. The clamp body is a product made of a silicon-magnesium-aluminium alloy, and an electric force compounded grease layer is coated on the surface of the clamp body. According to the crimping clamp disclosed by the invention, material selection and reasonable design on a body structure are carried out, thus a copper wire and an aluminium wire are effectively connected in a transition manner, a constant and high enough contact pressure and the maximum contact area are obtained, low contact resistance can be maintained for a long time, and the overload capacity is strong. In a using process, along with variation of external environment and load condition, stable contact performance on connection between wires can be realized, the electric force compounded grease layer is coated on the surface of the clamp body, oxidation resistance and corrosion resistance are high, the service life is relative long, maintenance and overhaul are avoided, the copper aluminium wire transition crimping clamp disclosed by the invention can be repeatedly used for multiple times, and the maintenance cost is reduced. The copper aluminium wire transition crimping clamp disclosed by the invention is convenient to mount and has stable and reliable performance.
Description
Technical field
The invention belongs to adapted electricity equipment auxiliary technical field, particularly a kind of copper aluminum steel transition crimp wire clamp.
Background technology
At present, being connected of the voltage copper conductor of the aluminum conductor of distribution step down side and transformer metering units, the jointing clamp of use is made up of conductive connection plates and the housing pin that is positioned at the conductive connection plates two-end part usually.When implementing wiring, the aluminum steel that the distribution step down side is drawn and the voltage copper cash of transformer metering units adopt hand wiring mode respectively around bundle on two housing pins, and aluminum steel and copper cash are compressed respectively through housing pin.Long-term practice shows that this jointing clamp adopts hand wiring connected mode, though convenient installation and operation; But randomness is too big; The crimp quality poor reliability exists the conductor compression jointing area little, loose contact, couple corrosion, the easy scaling loss of crimping member problem such as come off; Cause equipment operation and power supply trouble, bring economic loss in various degree for electric power enterprise and user; Or the long-time back electric energy meter that uses shows decompression, and causes few metering or do not measure, and brought many troubles and inconvenience for the electric-power metering maintenance work, also caused the business electric quantity loss simultaneously, and directly influence business is examined the line loss index.Secondly, the jointing clamp that uses at present generally adopts the low-carbon steel material product, because of the wind and weather Exposure to Sunlight is very easily got rusty, corrosion spalling, cause to connect electricity and connection device operation troubles thereof in the long-term open-air use, and a little less than the overload capacity, the conduction transiting performance is poor.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome defective of the prior art, overload capacity is strong, and non-oxidizability and corrosion resistance are strong, stable and reliable for performance, can prevent the copper aluminum steel transition crimp wire clamp that the scaling loss of lead and crimping member comes off effectively.
A kind of copper aluminum steel transition crimp wire clamp comprises the tubulose wire clip body and is arranged on the housing pin on the wire clip body that said housing pin is connected with said wire clip body through screwed hole, and the end of said housing pin is provided with the wiring pressing plate.
Said wire clip body adopts the magnesia-alumina-silica product.
Said wire clip body surface scribbles the electric force compounded grease layer.
Said wire clip body adopts the special-shaped tubular structure.
The quantity of said housing pin is at least two.
The bottom side of said wiring pressing plate is provided with arc groove.
Copper aluminum steel transition crimp wire clamp of the present invention; Through the appropriate design of Material Selection and physique structure, the effective transition of copper cash and aluminum steel is connected, have constant and enough big contact pressure and maximized contact area; Can keep low-down contact resistance for a long time, overload capacity is strong.And, in use, along with the variation of external environment and loading condiction; Connection between lead is had the stable contact performance, and in addition, the surface of wire clip body scribbles the electric force compounded grease layer; Non-oxidizability and corrosion resistance are strong, have long useful life, and be non-maintaining; Exemption from inspection can be repeatedly used, and reduces maintenance cost.This wire clamp is easy for installation, and is stable and reliable for performance.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view among Fig. 1.
Embodiment:
As shown in Figure 1: copper aluminum steel transition crimp wire clamp of the present invention, have the wire clip body 1 of a tubulose, through screwed hole at least 2 housing pins 2 are installed on this wire clip body 1.In wire clip body 1, be provided with the wiring pressing plate 4 that touches mutually with said housing pin 2 ends, be used for compressing of copper, aluminum conductor 5,6, the bottom side of this wiring pressing plate 4 is provided with arc groove 7, and making it has maximum envelope contact area with copper, aluminum conductor 5,6.Said wire clip body 1 adopts the magnesia-alumina-silica product; Utilize magnesia-alumina-silica to have elasticity; Further increase the crimping area of wire clip body and copper, aluminum conductor, and can keep contact pressure constant between lead and wire clamp for a long time, constant and enough big contact pressure and maximized contact-making surface can keep low-down contact resistance for a long time; Strengthen the overload capacity of connecting portion, simultaneously lead is formed the pressure stable load.Said wire clip body 1 surface scribbles electric force compounded grease layer 3; Very strong anti-oxidant, corrosion resistance are arranged, and electric conductivity is also very strong, can prevent the oxidation and the corrosion of wire clip body 1 effectively; Increase the service life, and remain that good connection is led, electrical property.The wire clip body 1 of magnesia-alumina-silica material and the electric conductivity that protective layer had of electric force compounded grease material, the connector electric conductivity that makes copper- aluminum conductor 5,6 and wire clip body 1 form obtains effective transition.Said wire clip body 1 adopts the special-shaped tubular structure, makes its body compact more, and guarantees itself and copper-aluminum conductor 5, has bigger contact area between 6.
Copper aluminum steel transition crimp wire clamp of the present invention through the appropriate design of Material Selection and physique structure, makes it in use; Along with the variation of external environment and loading condiction, the connection between lead is had the stable contact performance, and also non-maintaining; Exemption from inspection; Reduce maintenance cost, can be repeatedly used, belong to environmental protection and energy saving property product.This jointing clamp is peeled off backbone copper insulation joint point with electrician's instrument in use, and strip length is about 20 ~ 25mm; Again length an end that is about 35 ~ 40mm aluminum conductor and the insulation backbone copper conductor that strips are carried out the crimping encapsulation, lead (aluminum steel) other end inserts the inlet side of wire clip body, wire clip body go out the phase voltage line (copper cash) that termination is gone into electric energy meter.Then, tighten the hold-down bolt on the wire clip body respectively, make hold-down bolt suppress the wiring pressing plate in the wire clip body, it is connected the effective transition of low pressure side line (aluminum steel) and pressure-wire (copper cash) gets final product with spanner.
