Abstract
The invention discloses a special-shaped parallel groove clamp. The special-shaped parallel groove clamp includes an upper pressing component and a lower pressing component; wire clamping grooves are arranged between the upper pressing component and the lower pressing component; the outer surface and the inner surface of the upper pressing component intersect with each other at tail ends, so that tilted ends can be formed; the tilted ends are bent inwards, so that inwards-bent hooks can be formed; the tilted ends are fittingly attached to the inner surface of the lower pressing component; and the inward-bending radian of the tilted ends is larger than 90 degrees. With the above technical scheme of the invention adopted, rain will not penetrate the wire clamping grooves. The special-shaped parallel groove clamp is of an integrally-molded structure, and therefore, mechanical strength can be ensured, and at the same time, sealing requirements can be satisfied.
Description
Technical field
The present invention relates to power circuit field, especially relate to a kind of Special-shaped parrel-slot cable clamp.
Background technology
In the connection of electrical lead, usually will use the ability that unlike material wire continues conduct power indirectly, therefore, Special-shaped parrel-slot cable clamp arises at the historic moment.In electric power system, most element all needs to be arranged on open air, and Special-shaped parrel-slot cable clamp equally also can be exposed to outdoor.Inevitably, in time running into rainwater or snow sky, in Special-shaped parrel-slot cable clamp, have water enter, affect the useful life of wire clamp on the one hand, easily cause the connecting wire electricity in wire clamp on the other hand, cause the fault of power delivery circuit.Can install bucker in the outside of Special-shaped parrel-slot cable clamp in prior art, meanwhile bring the inconvenience of Special-shaped parrel-slot cable clamp installation and removal, the design of bucker also causes the increase of wire clamp cost of manufacture.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is to propose a kind of Special-shaped parrel-slot cable clamp.
Object of the present invention will be achieved by the following technical programs: a kind of Special-shaped parrel-slot cable clamp, comprise casting die and piece under pressure, wire clamp groove is provided with between described upper casting die and described piece under pressure, the outer surface of described upper casting die and inner surface intersect at end and are formed to tilt and hold, crotch in described tilting end introversion becomes, the described end that tilts fits with the inner surface of described piece under pressure, and the described introversion radian tilting end is greater than 90 °.
Preferably, above-mentioned a kind of Special-shaped parrel-slot cable clamp: the two ends introversion of described piece under pressure becomes hook solid.
Preferably, above-mentioned a kind of Special-shaped parrel-slot cable clamp: the bending two ends degree of described piece under pressure is greater than 90 °.
Preferably, above-mentioned a kind of Special-shaped parrel-slot cable clamp: described upper casting die is fixedly connected with by bolts and nuts with between described piece under pressure.
Preferably, above-mentioned a kind of Special-shaped parrel-slot cable clamp: the shape of described wire clamp groove is oval or circular.
Preferably, above-mentioned a kind of Special-shaped parrel-slot cable clamp: described tilting end is one or two.
Preferably, above-mentioned a kind of Special-shaped parrel-slot cable clamp: the space size of described wire clamp groove is regulated with the fitting area of described piece under pressure by the described end that tilts.
Preferably, above-mentioned a kind of Special-shaped parrel-slot cable clamp: described tilting end and described upper casting die one-shot forming.
Outstanding effect of the present invention is: 1) the bending setting of upper casting die and piece under pressure, no matter make the installation site of Special-shaped parrel-slot cable clamp, rainwater can not be entered by the gap between two casting dies, the good airproof performance of Special-shaped parrel-slot cable clamp, and overall structure is good; 2) upper inwall between casting die and piece under pressure can be fitted movement, thus the spatial accommodation of adjustment wire clamp groove, ensures that Special-shaped parrel-slot cable clamp meets varying cross-section and to amass or the wire of varying number enters; 3) upper casting die adopts integral one-step molding structure, has both ensured the robustness of casting die, ensures again to tilt end and the joining place good airproof performance of other parts, can not cause the infiltration of ponding.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of Special-shaped parrel-slot cable clamp.
Embodiment
As shown in Figure 1, a kind of Special-shaped parrel-slot cable clamp of the present embodiment, comprise casting die 1 and piece under pressure 2, upper casting die 1 is fixedly connected with being installed by bolt 5 between piece under pressure 2, the inner surface of upper casting die 1 is provided with the circular arc wire casing of indent, piece under pressure 2 upper surface is provided with the circular arc indent wire casing corresponding with the wire casing of upper casting die 1, and both are mutually corresponding, forms the wire clamp groove 3 holding wire.The outer surface of upper casting die 1 and inner surface intersect at end and are formed and tilt end 4, the two ends of piece under pressure 2 form corresponding sweep equally, tilt end 4 introversion and become interior crotch, tilt end 4 to fit with the crotch inner surface of piece under pressure 2, namely movement that between the two can be mutual, remains sealing state both cutting in moving process.The introversion radian tilting end 4 is greater than 90 °, can ensure that rainwater can not stretch into wherein with the junction of piece under pressure 2 by upper casting die 1 like this, and be integrated between tilting end 4 and other parts of upper casting die 1, ensure that the ponding tilting end 4 can not infiltrate in wire clamp groove.
When the Special-shaped parrel-slot cable clamp of the present embodiment is installed, only bolt 5 need be unclamped, the wire of unlike material be put into two wire clamp grooves 3, then cover casting die 1 and piece under pressure 2, tight a bolt 5.If increase the number of conductors in adjustment wire clamp groove 3, only bolt 5 need be unclamped, upper casting die 1 is moved to appropriate location with piece under pressure 2 along fitting part.
The technique effect of the present embodiment is: by tilting the setting of end, rainwater can not infiltrate in wire clamp groove; While integrated structure ensures mechanical strength, the also requirement of robust sealed.
Optionally, upper casting die 1 also can be square, trapezoidal or other shapes with the circular arc wire casing of piece under pressure 2.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
