Description
Technical field
Strain clamp technical field is the utility model is related to, specifically provides a kind of integrated precast strain clamp.
Background technology
Strain clamp is the gold for being used on overhead power line and electric substation's strain rod tower fix conducting wire in electric system
Tool, conducting wire is connected by it with insulator chain, and insulator chain is connected with steel tower again, is led to carrying the pulling force of conducting wire and forming electric current
Road.The strain clamp of fixed conducting wire by wire clip body, the conduction wire clamp being connected with wire clip body and inserts wire clip body aluminium at present
Steel anchor composition in tube portion.During installation, the drainage plate of conduction wire clamp and wire clip body is bolted, due to therebetween
Contacted for face, to meet current-carrying requirement, the processing, transport and installation requirement to gold utensil are higher, due to conducting wire, the gentle breeze of drainage thread
Vibration and conduction wire clamp, wire clip body drainage plate and bolt expand with heat and contract with cold caused by material difference difference be used in fasten drain
There is the possibility loosened in the attachment bolt of wire clamp and wire clip body drainage plate, add conduction wire clamp and connect with wire clip body drainage plate
The resistance of contacting surface, causes the fever of strain clamp, and the safe operation to electric power impacts.
Therefore, the improvement in structure how is carried out to existing strain clamp, to avoid wire clip body and conduction wire clamp it
Between existing fever hidden danger, become people's urgent problem to be solved.
Utility model content
In consideration of it, the purpose of this utility model is to provide a kind of integrated precast strain clamp, to solve wire clip body
There is the problem of fever hidden danger between conduction wire clamp.
Technical solution provided by the utility model is：Integrated precast strain clamp, including：Wire clip body and with wire clamp master
The steel anchor of body crimping, wherein, wire clip body is L-shaped, and the both ends of wire clip body are respectively conduit and drainage tube, the conduit
It is used to be inserted into after drainage thread with draining wire crimp with conductor compression jointing, the drainage tube after conducting wire for being inserted into.
It is preferred that the empty intra-bladder instillation aluminium core connected in the wire clip body with drainage tube, to prevent from passing through line in drainage tube
The cavity water inlet of clip main body, protection drainage tube under cryogenic will not the spalling because of water freezing.
Further preferably, crimping mark is both provided with the outside of the conduit and drainage tube, for prompting rising for crimping
Beginning position.
Integrated precast strain clamp provided by the utility model is effectively by wire clip body, conducting wire, drainage thread and steel anchor
Firmly it is crimped together to form good conductor, and to conducting wire without any damage, wire clip body both ends are respectively conduit and drainage tube,
Conduit and drainage tube be respectively used to conducting wire and drainage wire crimp, realize water conservancy diversion.
Integrated precast strain clamp provided by the utility model, rational in infrastructure, impact resistance fatigue resistance is strong, carrying holds
Power is strong, reduces intermediate current-carrying transition connection, improves security reliability, suitable to promote and apply.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is described in further detail the utility model：
Fig. 1 is integrated precast strain clamp structure diagram.
Embodiment
The utility model is further explained below in conjunction with specific embodiment, but does not limit to this practicality
It is new.
As shown in Figure 1, the utility model provides a kind of integrated precast strain clamp, including：Wire clip body 1 and and line
The steel anchor 2 that clip main body 1 crimps, wherein, wire clip body 1 is L-shaped, and the both ends of wire clip body 1 are respectively conduit 11 and drainage tube
12, the conduit 11 is used to being inserted into after conducting wire to be used to being inserted into after drainage thread and drainage thread with conductor compression jointing, the drainage tube 12
Crimping.
The integrated precast strain clamp is rationally and effectively combined together conducting wire and drainage thread by wire clip body, is not required to
Conduction wire clamp is bolted, solve due to size of finished face precision not enough, fastening bolt when torque be not easy grasp and
During long-play the problem of fastener coming loose, the safe and reliable connection of drainage thread and overhead power transmission conducting wire is effectively realized, from
And ensure the safe and stable operation of power grid and electrical equipment, simultaneously because it is resistance to so as to reduce to eliminate conduction wire clamp and fastener
The weight of bracing cable folder, has reached energy-saving target, great application value and vast potential for future development.
To prevent from intaking by the cavity of wire clip body in drainage tube, protection drainage tube under cryogenic will not be because of water knot
Ice and spalling, as the improvement of technical solution, as shown in Figure 1, the interior filling of cavity connect in the wire clip body 1 with drainage tube 12
Note aluminium core 13.
As the improvement of technical solution, the outside of the conduit 11 and drainage tube 12 is both provided with crimping mark, is used for
The initial position of crimping is prompted, when conducting wire is inserted into conduit and is anchored after touch with steel, with hydraulic method to wire clip body from conducting wire
Guide conduit end is crimped at crimping mark 31, so that steel anchor, conducting wire and wire clip body are connected as one, afterwards, will
To at aluminium core in drainage thread insertion drainage tube, with hydraulic method to wire clip body at drainage thread crimping mark 32 to drainage tube end
Crimped, so that steel anchor, drainage thread and wire clip body are connected as one.
Specific embodiment of the present utility model is write according to progressive mode, highlights each embodiment party
The difference of case, its similar portion can be with cross-reference.
The embodiment of the utility model is elaborated above in conjunction with attached drawing, but the utility model is not limited to
The above embodiment, within the knowledge of a person skilled in the art, can also not depart from the utility model
Various changes can be made on the premise of objective.
