Description
Technical field
The utility model relates to a kind of binding clip of high and low voltage electric distribution circuit, particularly relates to a kind of wire clamp of installing for electric power.
Background technology
Wire clamp (also referred to as binding clip, electric wire connecting junction or parallel groove clamp) is a kind of conventional electric armour clamp, and according to design feature, wire clamp is divided into bolt type, H type and wedge shape.Wherein the primary structure (as shown in Figure 4) of bolt type wire clamp comprises wire clamp 2, drop wire clip 4 and bolt assembly 1, wherein bolt assembly 1 forms primarily of nuts and bolt, bolt (English: bolt), for the shaft-like object of taking the lead of attached threaded cylinder, the screwed cylinder part in one end is called stud, for with nut screw connection, the other end is head, be called bolt head, upper and lower wire clamp is located between bolt head and nut, and between described upper wire clamp 2 and drop wire clip 4, clamping is formed with two clamp holes 3.
Wire clamp is mainly used in the wire jumper of high-tension line and low-voltage power line line pole tower, the continuing of shunt line.Example is installed as now with shunt line, introduce the operation principle of wire clamp: to be penetrated into by main line in wire clamp in a clamp hole 3, shunt line is penetrated in another clamp hole 3, with drop wire clip 4, main line and shunt line are clamped by bolt assembly 1, upper wire clamp 2.And upper wire clamp 2 and the clamp 4 that rolls off the production line itself possess electric conductivity, such wire clamp not only realizes main line and shunt line merging spatially, also achieves both electrical energy transfer.What deserves to be explained is, upper wire clamp 2 and drop wire clip 4 are respectively equipped with the serration for pierce cable insulating outer layer, even if do not peel off insulating outer layer like this, wire clamp also can be electrically connected with cable; If certainly directly peel off the insulating outer layer of one section of cable, then penetrate in clamp hole 3 by corresponding naked core, circle design can be led in that clamp hole 3, without the need to above-mentioned serration.
Because whole wire clamp only relies on bolt assembly 1 to realize connecting, if occur between bolts and nuts to loosen, the contact gap of upper and lower wire clamp and cable will be increased, and then the contact resistance of wire clamp and cable also can increase thereupon, the electric conductivity of wire clamp itself reduces, and the effect that continues of the electric energy between cable is had a greatly reduced quality.
Utility model content
The utility model is intended to provide a kind of electric power to install wire clamp, with anti-loosening bolt assembly, ensures the electric conductivity of wire clamp itself.
Electric power in this programme installs wire clamp, comprise wire clamp, drop wire clip and bolt assembly, wherein bolt assembly comprises bolt and nut, described bolt comprises bolt head and screw rod, described nut is provided with the screwed hole be connected with described screw flight, upper and lower wire clamp is located between bolt its head and nut, and between upper wire clamp and drop wire clip, clamping forms clamp hole; The opposing one side of described nut itself and bolt is provided with the located lateral groove that one group of circumference distributes, and described located lateral groove all passes into described screwed hole; Described bolt entirety is made up of aluminium; Its bottom of described screw rod is provided with one group of uniform vertical spacer of circumference, and position and the shape of described vertical spacer and located lateral groove are corresponding.
The utility model is adopted to have following technique effect:
Need during installation with drop wire clip, cable to be clamped, then by drop wire clip on bolt-through, screw rod bottom is exposed.At this moment again nut is screwed on screw rod; Then the vertical spacer of screw rod bottom is folded in the located lateral groove of nut.Because the position and shape of stating vertical spacer and located lateral groove are corresponding, each vertical spacer and located lateral slot fit, nut can be realized locate relative to the circumference of screw rod, avoid, between nut and screw rod, circumferential deflection occurs, and nut is connected with screw flight, also cannot axial dipole field be there is in both when circumferential deflection.
Described bolt entirety is made up of aluminium, is one-body molded in order to ensure vertical spacer and screw rod, and still keeps the feature of certain metal strength after can utilizing aluminium bending, guarantee that vertical spacer can not be damaged because of bending.
Just loosening of bolt assembly can be prevented thus, gap between upper and lower like this wire clamp can be guaranteed, the electric conductivity of the contact resistance of wire clamp and cable and wire clamp itself also can not change, and the electric energy finally maintained between good cable continues effect.
Further, described nut outer side edges is along being provided with between described located lateral groove the opening communicated.
In order to strengthen described vertical spacer located lateral groove between gripping effect, by nut outer side edges along and described located lateral groove between offer opening, vertical spacer can be made always to be folded into edge outside nut, to make vertical spacer locking nut better.
Further, also comprise the outside housing cover mated with described nut shape, described screw rod center bottom is provided with embedded hole, and described outside housing cover is provided with the convex key with described embedded hole form fit.
During use, only need according to shape corresponding, outside housing cover is covered on nut, and described convex key should insert in embedded hole.Setting up one be plugged on screw rod and cover the outside housing cover on nut, is the connection in order to strengthen further between nut and screw rod, avoids relative motion occurs.
Further, described nut is hex nut, described nut is provided with altogether six located lateral grooves, and described embedded hole is hexagon ring.
If described nut is round nut, embedded hole is circular hole, then the locking effect of above-mentioned outside housing cover can weaken relatively.Therefore individual features is defined as and is different from circular hexagon.
