Abstract
The utility model discloses a contact line terminal anchoring clamp. The contact line terminal anchoring clamp comprises a clamp body, and is characterized in that the clamp is integrally in a V-shaped structure, the two sides of the upper end of the clamp are respectively provided with an encapsulation hole, a pin is arranged in each encapsulation hole, a socket is formed in the bottom end of the clamp, a tapered wedge is also inserted in the clamp, a tapered hole is formed in the tapered wedge, and a tapered hole wall is provided with sawtoothed antislip threads. The clamp body is formed through casting a cast copper alloy material with high strength and good toughness at one time and is in an integral structure, and the tapered hole wall is provided with the sawtoothed antislip threads, so that the clamp has high integral structural strength and good slip resistance, and is suitable for the requirements of lines and cables with large tension and heave load. Moreover, the clamp is low in production cost, and is more convenient to install, debug and maintain; and reinforcing ribs are processed on the outer wall of the clamp body, and furthermore, the structural strength is improved.
Description
Technical field
The utility model relates to a kind of fixing and holding mechanism, is specifically related to a kind of termination fitting for contact wire.
Background technology
The contact wire of contact nets in electrified railways in use needs segmentation to cast anchor or connection segment inevitably, terminal anchoring clamp is exactly the strength member that connects with other parts for the contact wire termination, and how the performance of terminal anchoring clamp directly affects the safety of whole electrified contacting nets.
Existing termination fitting for contact wire is that contact wire is penetrated in the chock hole, and contact wire is dispersed between chock and the cone cylinder bolt, by tightening a cone cylinder bolt, and the wedging contact wire, by the contact wire extruding, chock radial shrinkage and contact wire is clamped simultaneously.Because contact wire is yielding, therefore the gripping power to chock is just less, and chock is also just less comparatively speaking to the gripping power of contact wire like this, and contact wire just skids when pulling force acquires a certain degree, and is not suitable for the clue operating needs of hightension, heavy lift.
The utility model content
For above-mentioned prior art, the technical problems to be solved in the utility model is: a kind of hightension, heavy lift, superior performance, safe and reliable terminal anchoring clamp of being applicable to is provided.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of termination fitting for contact wire, comprise wire clip body, it is characterized in that: the whole V-shaped structure of wire clamp, wire clamp upper end two walls are provided with encapsulated holes, encapsulated holes is provided with pin, and the bottom of wire clamp has plug wire hole, also is fitted with the taper chock in the wire clamp, have taper hole in the taper chock, hole wall is provided with is with zigzag antiskid thread.
The outer wall of described wire clamp is shaped with reinforced rib.
Described wire clamp is through a cast molding of cast alloy materials.
Described taper chock adopts stainless steel material to process.
Compared with prior art, the utlity model has following beneficial effect:
Intensity is high because wire clip body adopts, a cast molding of casting copper alloy material of good toughness, be an integral structure, with zigzag antiskid thread, overall construction intensity is high in the taper chock hole, antiskid capability is good, is applicable to the clue operating needs of hightension, heavy lift.And productive costs is low, installs, debugs and keep in repair more convenient; Be shaped with reinforced rib on the outer wall of wire clip body, further improved structural strength.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Reference numeral is: 1 is that wire clamp, 2 is that pin, 3 is that taper chock, 4 is antiskid thread.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and the specific embodiments.
A kind of termination fitting for contact wire, comprise wire clamp 1 body, the whole V-shaped structure of wire clamp, wire clamp upper end two walls are provided with encapsulated holes, encapsulated holes is provided with pin 2, and the bottom of wire clamp has plug wire hole, also is fitted with taper chock 3 in the wire clamp, have taper hole in the taper chock, hole wall is provided with is with zigzag antiskid thread 4.The outer wall of described wire clamp is shaped with reinforced rib.Described wire clamp is through a cast molding of cast alloy materials.Described taper chock adopts stainless steel material to process.
