Abstract
The utility model discloses a kind of M shaped cable clamps longitudinally crimped, including pressing plate one, intermediate wedge and pressing plate two, pressing plate one and pressing plate two are locked after converging intermediate wedge using two bolts, corresponding notch is provided between pressing plate one and intermediate wedge and pressing plate two and the contact of intermediate wedge, notch arcwall face structure, two notches constitute cable keying aperture, and cable keying aperture is arranged between two bolts.The utility model is laminated by the transverse direction of original parallel groove clamp and is improved to longitudinal extruding, section is M shape, increase the contact area of fitting and conducting wire, and M type structure can also increase lever moment and come into full contact with conducting wire with wire clamp, reduce contact resistance, under the same conditions compared to parallel groove clamp, calorific value will weaken significantly, since to send out failure rate thermogenetic just corresponding reduces for wire clamp.
Description
Technical field
The utility model relates to a kind of M shaped cable clamps longitudinally crimped, belong to wire clamp technical field.
Background technique
Currently, since wire clamp and conductor compression jointing power are lower than normal value, contact resistance is caused to increase in 10kV distribution line
Add, wire clamp temperature rise, phenomena such as burning, fuse, will result directly in line interruption and cause corresponding area large-area power-cuts, cause
Unnecessary loss.
Summary of the invention
Technical problem to be solved by the utility model is: a kind of M shaped cable clamp longitudinally crimped is provided, to solve the prior art
The problem of.
The technical solution that the utility model is taken are as follows: a kind of M shaped cable clamp longitudinally crimped, including pressing plate one, intermediate wedge
With pressing plate two, pressing plate one and pressing plate two are locked after converging intermediate wedge using two bolts, pressing plate one and intermediate wedge and pressing plate two
Corresponding notch, notch arcwall face structure are provided between the contact of intermediate wedge, two notches constitute cable keying aperture, and cable is stung
Hole is closed to be arranged between two bolts.
Preferably, above-mentioned intermediate wedge upper end two sides are up-small and down-big symmetrical arcwall face structure, with arcwall face structure pair
It answers and matched arcwall face structure is set on pressing plate one and pressing plate two, the square hole of upside bolt is provided through on the upside of intermediate wedge,
U notch is arranged in downside.
Preferably, the arcwall face of above-mentioned two notch is provided with salient point.
The utility model has the beneficial effects that compared with prior art, the utility model by original parallel groove clamp transverse direction
It laminates and is improved to longitudinal extruding, section is M shape, increases the contact area of fitting and conducting wire, and M type structure can also increase lever
Torque comes into full contact with conducting wire with wire clamp, reduces contact resistance, and under the same conditions compared to parallel groove clamp, calorific value will be significantly
Weaken, due to wire clamp just corresponding reduction of send out thermogenetic failure rate.

Specific embodiment
With reference to the accompanying drawing and the utility model is described further in specific embodiment.
Embodiment: as shown in figs 1 to 6, a kind of M shaped cable clamp longitudinally crimped, including pressing plate 1, intermediate wedge 2 and pressure
Plate 23, pressing plate 1 and pressing plate 23 are locked after converging intermediate wedge 2 using two bolts 4, pressing plate 1 and intermediate wedge 2 and pressing plate
Corresponding notch 5,5 arcwall face structure of notch are provided between 23 and the contact of intermediate wedge 2, two notches 5 constitute cable keying aperture
6, cable keying aperture 6 is arranged between two bolts 4.
Preferably, above-mentioned 2 upper end two sides of intermediate wedge are up-small and down-big symmetrical arcwall face structure, with arcwall face structure pair
It answers and matched arcwall face structure is set on pressing plate 1 and pressing plate 23, the side of upside bolt 4 is provided through on the upside of intermediate wedge 2
U notch 8 is arranged in hole 7, downside.
Preferably, the arcwall face of above-mentioned two notch 5 is provided with salient point.
The utility model can also judge whether crimp force reaches normal value and (demarcate real according to the degree of convexity of intermetallic metal block
Now), it can be freely combined between wire clamp metal block and wire range is wide (it is 70-150 that reducing, which can press from both sides range), type selecting is very convenient.
As shown in Figure 1, the lateral distance when pressing plate one (symmetrical with pressing plate two) is with separation beam plate closing of cable keying aperture 6 is
7mm is suitable for 70-95 line footpath.
As shown in Fig. 2, the lateral distance when pressing plate one (symmetrical with pressing plate two) is with separation beam plate closing of cable keying aperture 6
For 14.2mm, it is suitable for 95-150 line footpath.
As shown in Fig. 3, cable keying aperture 6 pressing plate one and pressing plate two it is symmetrical respectively with separation beam plate closing when laterally away from
From for 14.2mm and 7mm, it is suitable for 70-150 line footpath.
Above-mentioned pressing plate and separation beam board group are closed, it can be deduced that different applications.
The M type structure of the utility model wire clamp makes have reliable electrical connection between sliding block, different simultaneously for crimping
The conducting wire of line footpath can make corresponding adjustment to hole slot, and it is uneven to the conductor compression jointing power for crimping different line footpaths to solve parallel groove clamp
The problem of.
The major advantage of the wire clamp of the utility model: increasing contact force, connects to preventing corrosive gas, dust from entering electricity
There is some superiority on touching surface, also reduces film layer resistance while reducing contact resistance, effectively inhibits temperature.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model, therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
