Description
Technical field：
This utility model belongs to electrical engineering equipment technical field and in particular to a kind of safe wiring for electrical engineering
Head.
Background technology：
As shown in fig. 7, the electrical engineering lug such as the current socket using, distribution box is when carrying out wiring, first by wire
In the insertion circular hole of lug or square hole, then pass through screw fastened, this mode of connection has design defect, on the one hand in order that
Wire fastening needs to tighten screw, because conference of exerting oneself makes wire and the contact site of screw impression or crack line between the teeth, rear
It is susceptible to wire fracture phenomenon when continuous installation or regulation, there is potential safety hazard, on the other hand due to the tightening of wire and screw
Contact surface less so that in subsequent installation or operating process wire easily come off, thus leading to power-off or virtual connection phenomenon, safety
Property is relatively low.So, design a kind of it can be avoided that coming off or the safe lug for electrical engineering that breaks is very necessary.
Utility model content：
In place of this utility model makes up and improves above-mentioned the deficiencies in the prior art, there is provided a kind of structure is simple, design
Rationally, safe and reliable, be easy to connect, with low cost, be widely used, a kind of economic and practical safe wiring for electrical engineering
Head, can promote on a large scale and use.
The technical solution adopted in the utility model is：A kind of safe lug for electrical engineering, this lug includes
Groove base, U-shaped clamping plate and bulb tight fixed bolt, groove base is provided with arc groove, and arc groove both sides are provided with circular arc and fall
Angle, U-shaped clamping plate top is provided with screwed hole, and bulb tight fixed bolt is connected with U-shaped clamping plate by screwed hole, bulb tight fixed bolt end
It is provided with hemispherical bulb；Groove base is welded in the U-type groove of U-shaped clamping plate, and wire passes through groove base and U-shaped clamping plate to be formed
In cavity, and extruded in the arc groove being fixed on groove base after bending by bulb tight fixed bolt.
The beneficial effects of the utility model：Structure is simple, reasonable in design, safe and reliable, is easy to connect, with low cost, should
With extensive, economic and practical it is easy to promoting on a large scale and using.Its major advantage is as follows：
1）, wire defines a U-shaped back bending under the extruding of bulb tight fixed bolt, and is clamped on the arc of groove base
In connected in star, such wire will not occur break-off when by horizontal pulling force, connects easy, safe and reliable.
2）, the end of described bulb tight fixed bolt be the design of hemispherical bulb, the both sides of described arc groove are provided with
Circular arc chamfering, so it can be avoided that when tightening bulb tight fixed bolt wire impression occurs and wire fracture occurs and cracks showing of line between the teeth
As, reasonable in design, safe and reliable.
3）, groove base by welding by way of be connected with U-shaped clamping plate, reduce difficulty of processing, cost-effective, improve
Economic benefit, reasonable in design, economic and practical.

Specific embodiment：
With reference to each figure, a kind of safe lug for electrical engineering, this lug includes groove base 4, U-shaped clamping plate 2
And bulb tight fixed bolt 1, groove base 4 is provided with arc groove 10, and arc groove 10 both sides are provided with circular arc chamfering 9, U-shaped clamping plate
2 tops are provided with screwed hole 6, and bulb tight fixed bolt 1 is connected with U-shaped clamping plate 2 by screwed hole 6, and bulb tight fixed bolt 1 end is provided with
Hemispherical bulb 8；Groove base 4 is welded in the U-type groove 7 of U-shaped clamping plate 2, and wire 3 passes through groove base 4 and U-shaped clamping plate 2 shape
In the cavity 5 becoming, and extruded in the arc groove 10 being fixed on groove base 4 after bending by bulb tight fixed bolt 1.
Wire 3 defines a U-shaped back bending under the extruding of bulb tight fixed bolt 1, and is clamped on the arc of groove base 4
In connected in star 10, such wire 3 will not occur break-off when by horizontal pulling force；Described bulb tight fixed bolt 1
End is designed for hemispherical bulb 8, and the both sides of arc groove 10 are provided with circular arc chamfering 9, so it can be avoided that tight tightening bulb
Determine wire 3 during bolt 1 impression to occur and occurs wire 3 to rupture and crack the phenomenon of line between the teeth；Groove base 4 by welding by way of and U
Type clamping plate 2 connects, and reduces difficulty of processing, cost-effective.Structure of the present utility model is simple, reasonable in design, safe and reliable, just
In connection, with low cost, be widely used, economic and practical it is easy on a large scale promote and use.
