Description
Technical field
This utility model is related to a kind of terminal anchoring clamp, and in particular to a kind of separation preventing ears wedge type terminal anchoring
Folder.
Background technology
Ears wedge type terminal anchoring clamp is one of most widely used product in electrifing railway contacting net system.It is by double
Ear wedge type cavity and chock composition, during use, twisted wire drives chock to microcephaly to move when twisted wire stress around chock in later shape,
Chucking power is formed between wedge chamber and chock, and is to draw tighter and tighter.The product has two aspect shortcomings：1. clamp the initial stage necessary
There is a starting force, it is ensured that twisted wire and chock are simultaneously mobile, can otherwise produce that chock is motionless, 2. the phenomenon that twisted wire is extracted out works as twisted wire
Generation tension force, chock when replacing that relaxes are likely to occur rollback phenomenon, the phenomenon for causing twisted wire to extract out.
Utility model content
This utility model is to solve existing ears wedge type terminal anchoring clamp easily because not applying starting force or chock
Rollback and cause twisted wire extract out problem, and then provide a kind of separation preventing ears wedge type terminal anchoring clamp.
This utility model by solving the technical scheme that adopts of above-mentioned technical problem is：
A kind of separation preventing ears wedge type terminal anchoring clamp, including ears wedge type cavity, chock, steady pin, the first nut,
Bolt pin, the second nut and split pin, ears wedge type cavity include main cavity and are parallel to each other being fixed in the two of main cavity one end
Individual otic placode, bolt pin are installed on two otic placodes and affixed by the second nut and split pin, and it is in circular arc that chock is two ends
Stripe board, wherein one end of chock is stub end, and the other end of chock is little head end, chock be located in main chamber body and chock with
Contain gap between main cavity, the stub end of chock is arranged towards one end of main cavity, and the little head end of chock is towards main cavity
The other end is arranged, and long through-hole is offered in the middle part of chock, and main cavity is fixedly connected by steady pin and the first nut with chock.
The side of chock offers the groove around the circle of chock one.
The stub end of chock is semicircle.
Steady pin be located on long through-hole near the position of chock little head end when, be initial position that twisted wire is clamped, steady pin
On long through-hole during the position of close chock stub end, it is the position of chock when twisted wire meets maximum tension.
This utility model is had the effect that compared with prior art：
Chock forms chucking power by the mobile twisted pair wire in ears wedge type cavity, and steady pin is to ensure chock along long through-hole
It is mobile, and chock initial position and chock rollback are limited, when actually used, it is necessary to which twisted pair wire applies starting force, just can guarantee that master
Hole on cavity is corresponding with the long through-hole on chock, and inserts steady pin, so as to eliminate human negligence forget plus starting force and lead
The phenomenon that the twisted wire of cause is extracted out, and steady pin is prevented from chock rollback, compared with existing wedge type terminal anchoring clamp, carries
The high reliability of terminal anchoring clamp.Terminal anchoring clamp of the present utility model passes through 2,000,000 vibration tests and 500,000 times
Fatigue test, did not occurred to take out de- phenomenon, and by lax, tensioning test, non-loosening sign.

Specific embodiment
Specific embodiment one：Present embodiment, a kind of separation preventing ears of present embodiment are illustrated with reference to Fig. 1～Fig. 7
Wedge type terminal anchoring clamp, including ears wedge type cavity 1, chock 2, steady pin 3, the first nut 4, bolt pin 5, the second nut 6
And split pin 7, ears wedge type cavity 1 includes main cavity 1-1 and is parallel to each other being fixed in two otic placode 1- of main cavity 1-1 one end
2, bolt pin 5 is installed on two otic placode 1-2 and affixed by the second nut 6 and split pin 7, and it is in circular arc that chock 2 is two ends
The stripe board of shape, wherein one end of chock 2 are stub end 2-1, and the other end of chock 2 is little head end 2-2, and chock 2 is positioned at main chamber
Body 1-1 is interior and contains gap between chock 2 and main cavity 1-1, and the stub end 2-1 of chock 2 is set towards one end of main cavity 1-1
Put, the little head end 2-2 of chock 2 is arranged towards the other end of main cavity 1-1, and the middle part of chock 2 offers long through-hole 2-3, main chamber
Body 1-1 passes through steady pin 3 with chock 2 and the first nut 4 is fixedly connected.
This utility model is connected to naked twisted wire terminal suitable for electrifing railway contacting net system.
The circular hole that for steady pin 3 pass through is offered on main cavity 1-1 symmetrically, chock 2 penetrates ears wedge by little head end 2-2
In the main cavity 1-1 of cavity 1, twisted wire passes main cavity 1-1 around 2 stub end 180 degree of chock, and twisted pair wire applies starting force, makes
