Transmitting and distribute the cable product of high-power power in the basic routing line of electric system, including 1 to 500KV and more than it is each
Kind voltage class, the power cable of various insulation.
Cable is made of the conductor and external insulating protective layer of one or more mutually insulated, by electric power or information from one
Place is transferred to the conducting wire at another place；It is needed in the installation process of cable using to cable connector.Current laying cable has very
It is all mostly mounted in open air, the case where connector once seeps water, the destruction to cable run is very big, and current electricity
Cable joint is mostly separate type, and structure is more complicated, is open more, and infiltration, and the junction meeting of connector and cable are easy
It has the gap, rainwater is also easy to enter out of gap.
Usually using wire stripper by the outside of two cable sockets to be connected when at present there are also some power cable wiring
Insulating layer removal, keeps core wire sufficiently exposed, then firmly kinks two core wires together, is finally connected using insulating tape winding
Socket part position, curls only according to connecting line, connects unstable, and leakproofness is poor, is prone to wear at general cable connection, damage or
Person destroys cable.
Summary of the invention:
In order to solve, structure existing for traditional cable connector in the prior art is more complex, opening is more, is easy lacking for infiltration
Point, the present invention provides a kind of power cable connector being different from the prior art, structure is simple, opening is few, and leakproofness is preferable
And stable connection.
To achieve the goals above, realization that the present invention adopts the following technical solutions:
A kind of power cable connector, including the first cable connector and the second cable connector, first cable connector and
Two cable connectors connect and structure is identical, and first cable connector and the second cable connector include insulating layer, the insulation
Layer is connect with bell flange, is equipped in the insulating layer and is equipped with one with the close-connected fastened layer of insulating layer, the fastened layer
Secondary clamping structure and secondary clamping structure.
Further, a clamping structure includes stress cone and spring, and the outer ring of the stress cone passes through fastened layer
Clamping, inner ring are mounted on contact cylinder, one end of the spring and stress cone clamping, and the other end connects by the way that bell flange is fixed
It connects.
Further, the secondary clamping structure includes holding screw, and the holding screw passes through insulating layer and fastened layer.
Further, the secondary clamping structure includes torsional spring, connecting plate and head clamp, and the connecting plate is mounted on insulation
On layer and fastened layer, the connecting plate is connect with head clamp, and the both ends of the torsional spring are stuck on connecting plate and head clamp.
Further, the insulating layer is connect by screw with bell flange.
Further, sealing ring is equipped in the bell flange.
Further, the secondary clamping structure is equipped with four to eight places, radial to be stuck on the excircle of cable.
Compared with prior art, the beneficial effects of the present invention are:
1, the configuration of the present invention is simple, opening are few, and leakproofness is preferable, stable connection, and junction electric conductivity is preferable and will not
Damage cable；
2, using a clamping structure, preliminary clamping is carried out when can insert the cable into cable connector, prevents from leaping up out；
3, using secondary clamping structure, secondary clamping structure is stuck on the excircle of cable and carries out clamping again, into one
Step guarantees that cable will not leap up out；
4, by the sealing ring of bell flange and inside, clamping three times may be implemented, on the basis of guaranteeing solid enough
It is avoided that rainwater penetrates into cable again.

Specific embodiment:
Below by specific embodiment and in conjunction with attached drawing, the invention will be further described.
Embodiment 1:
As shown in Figure 1, a kind of power cable connector, including the first cable connector and the second cable connector, first electricity
Cable joint is connected with the second cable connector and structure is identical, and first cable connector and the second cable connector include insulating layer
2, the insulating layer 2 is connect with bell flange 6, be equipped in the insulating layer 2 with the close-connected fastened layer 3 of insulating layer 2, it is described
Fastened layer 3 is equipped with a clamping structure and secondary clamping structure.
Clamping structure includes stress cone 4 and spring 5, and the outer ring of the stress cone 4 passes through 3 clamping of fastened layer,
Inner ring is mounted on contact cylinder 8, and one end of the spring 5 and 4 clamping of stress cone, the other end are fixedly connected by bell flange 6.
Embodiment 2:
As shown in Figure 1, a kind of power cable connector, the secondary clamping structure includes holding screw 7, the holding screw
7 pass through insulating layer 2 and fastened layer 3.Other parts are same as Example 1.
The working principle of the present embodiment are as follows:
It is structure as a whole after first cable connector and the connection of the second cable connector, centre is connected simultaneously by conductive transition body 1
First cable 9 is inserted into the contact cylinder 8 in the first cable connector when use by conduction, is continued into until with conductive transition body 1
Then connection is given 9 one vertical forces of the first cable by rotation holding screw 7, is tightened, and stress cone 4 is with flexible
, the diameter of contact cylinder 8 is just less than the diameter of the first cable 9 before the use, therefore just exists when the insertion of the first cable 9
