Abstract
The utility model discloses a maintenance-free C-shaped connecting wire clip, which mainly comprises an outer limiting component with a 'C'-shaped cross section, an inner wedge with wire casings and backstop teeth, a backstop limiting clamp, rivets and a clamp ring, wherein the outer limiting component and the inner wedge longitudinally form wedge shapes with an identical included angle; when moving inwards along the included angle, the inner wedge can clamp two conducting wires between the wire casings of the inner wedge and wire casings of the outer limiting component; one end of the backstop limiting clamp is riveted on one side of the outer limiting component by the rivet, and can rotate about the rivet; a waist-shaped hole is formed in the other end of the backstop limiting clamp; the clamp ring is riveted to the other side of the outer limiting component by the other rivet in a waist shape, and can rotate; after passing through the clamp ring, the backstop limiting clamp can be prevented from being separated from the clamp ring by rotating the clamp ring; when the outer limiting component is stressed and opened to a certain degree, the clamp ring blocks and prevents the backstop limiting component from being opened excessively, and gives an indication; a backstop tongue of the backstop limiting clamp clamps the teeth in a backstop groove of the inner wedge, so that the inner wedge can be prevented from moving back to further prevent the loosening of the pressed conducting wires from causing poor connection; and the 'C'-shaped outer limiting component can be expanded with heat and contracted by cold along with the conducting wires to press tightly the conducting wires all the time. Compared with the prior art, the maintenance-free C-shaped connecting wire clip has the advantages of simple structure, convenience for mounting, capabilities of giving an indication that the outer limiting component is opened enough and preventing the inner wedge from being loosened, applicability to a wide range of conducting wires, no need of maintenance and the like.
Description
Technical field
The utility model relates to a kind of connecting clip; Belong to non-bearing connector field in the electric power networking; According to our called after " non-maintaining C type connecting clip " of its design feature, this wire clamp is specially adapted to that main line continues with the wire jumper that the offset of sub-line is connected between work and the main line in the electric power networking.
Background technology
Existing electric power has various connecting clips in the networking, and commonly used have a parallel groove clamp, it is characterized in that utilizing bolt and clamping plate directly lead to be clamped, loosening easily.Also have a kind of C type connecting clip, be made up of the interior wedge of outer limit element of the C type that is tapering and wedge type, install with the specific purpose tool that explosive is housed, extremely inconvenience is installed, and the lead scope that is suitable for is little, model specification is many.China's utility model patent " a kind of wedge type automatic locking principal vertical line folder " (ZL200620096465.2) has been introduced a kind of improved wedge type automatic locking principal vertical line and has been pressed from both sides; It is characterized in that the zigzag self-locking back stop slot that snaps in the locking tongue is arranged at C type element top or chock bottom; The locking tongue other end has shell fragment or spring; The other end of shell fragment or spring has screw, and the locking tongue is arranged in the locking hole of C type element or chock.Though this utility model patent have prevent in the loosening effect of wedge, have complex structure, the indication that do not put in place when installing, will cause shortcoming such as stopping effect inefficacy like screw loosening.
Summary of the invention
The utility model provides a kind of improved non-maintaining C type connecting clip, has possessed simple in structure, easy for installation and provides the indication that puts in place, is suitable for advantages such as the lead scope is big, anti-loosening and non-maintaining.
The technical measures of implementing the utility model non-maintaining C type connecting clip above-mentioned purpose and adopting are described below: this non-maintaining C type connecting clip comprises that a cross section is the spacing card of interior wedge 2, the stopping of the outer limit element 1 of " C " shape, band wire casing and anti-back tooth 3, snap ring 6, rivet 4 and 5; It mainly is outer limit element 1 and interior wedge 2 at the wedge type that vertically is equal angular, when interior wedge 2 when this angle moves inward, can clamp interior wedge line groove 21 and outside two leads between the limit element wire casing 11; The outer limit element 1 of " C " shape can expand with heat and contract with cold with lead, compresses lead all the time.Spacing card 3 one ends of stopping are riveted on a side of outer limit element 1 by rivet 4 and can are that rotate at the center with rivet 4; The other end has a mounting hole 32; The axle sleeve that snap ring 6 is waist type boss is also turned by the opposite side that another rivet 5 is riveted on outer limit element 1; After the spacing card 3 of stopping passes, rotate snap ring 6 and can stop the spacing card 3 of stopping to be deviate from, outer limit element 1 is stressed when opening up into to a certain degree, and snap ring has been lived the spacing card 3 of stopping for 6 grades, prevents that outer limit element 1 from opening excessive and provided indication; The locking tooth 22 of wedge in the stopping tongue 33 of the spacing card 3 of stopping blocks, wedge 1 is retreated and is caused that line ball is loosening to cause bad connection in can preventing.
The length of the interior wedge 2 of said non-maintaining C type connecting clip is longer than the length of outer limit element 1, and interior wedge 2 can move inward long distance by external mutually limit element 1 along the wedge type angle along directions X, thereby clamps the lead of different-diameter; One end of interior wedge 2 is provided with the abundant anti-back tooth 22 vertical with interior wedge moving direction, can both prop up the stopping tongue 33 on the spacing card 3 of stopping in different positions, and wedge is retreated in preventing.
Can know that from above-mentioned improvement compared with present technology the present technique scheme has following advantage:
1, simple in structure, easy for installation and be given to bit flag;
2, suitable lead scope is big;
3, wire clamp is the C type and expands with heat and contract with cold with lead and compress lead all the time;
4, prevent that interior wedge is loosening, non-maintaining.
