The utility model has reasonable and compact structure and convenient use, and can realize the complete cutting and reduction of the vertical edges and corners at the wire inlet and outlet positions of the existing parallel groove clamp by rounding the upper clamping plate and the lower clamping plate corresponding to the wire clamping groove, thereby avoiding the occurrence of strand breakage and wire breakage after a wire is cut by the edges and corners.
Description
Technical Field
The utility model relates to the technical field of wire splicing fittings, in particular to an anti-abrasion parallel groove clamp.
Background
The parallel groove clamp is mainly used for connecting aluminum stranded wires or steel-cored aluminum stranded wires with middle and small cross sections and steel stranded wires of overhead lightning conductors at positions which do not bear tension, such as T-connection wires at non-bearing connection positions, branch wires, down leads of electrical equipment such as switches and transformers, grounding down leads of lightning conductors and the like, and can also be used for jumper connection of non-linear towers. The parallel groove clamp used at present is easy to be cut by the perpendicular edges and corners of the inlet and outlet of the parallel groove clamp due to the fact that the length of the clamped wire is short and the wire can swing under the action of wind load, abrasion and fatigue damage occur to the wire, the wire is broken, and the safe operation of the wire is seriously influenced.
Disclosure of Invention
The utility model provides an anti-abrasion parallel groove clamp, overcomes the defects of the prior art, and can effectively solve the problem that the existing parallel groove clamp causes strand breakage and wire breakage of a wire due to abrasion and fatigue damage of the wire at the wire inlet and the wire outlet of the parallel groove clamp under the action of wind vibration.
The technical scheme of the utility model is realized by the following measures: an anti-abrasion parallel groove clamp comprises a lower clamp plate, an upper clamp plate and a threaded fastener, wherein the upper clamp plate is arranged above the lower clamp plate, and the lower clamp plate and the upper clamp plate are fixedly installed together through the threaded fastener; two arc-shaped lower grooves with upward openings are arranged in the middle of the upper side of the lower clamping plate at the front and back intervals, an arc-shaped upper groove with a downward opening is arranged on the lower side of the upper clamping plate corresponding to each lower groove, each lower groove and the corresponding upper groove form a wire clamping groove, and rounding is arranged on the upper clamping plate and the lower clamping plate corresponding to the left end and the right end of each wire clamping groove.
The following are further optimization or/and improvement of the technical scheme of the utility model:
the upper clamping plate can comprise at least two short clamping plates arranged at left and right intervals.
The left end and the right end of the short clamping plate corresponding to each wire clamping groove can be provided with rounding.
The utility model has reasonable and compact structure and convenient use, and can realize the complete cutting and reduction of the vertical edges and corners at the wire inlet and outlet positions of the existing parallel groove clamp by rounding the upper clamping plate and the lower clamping plate corresponding to the wire clamping groove, thereby avoiding the occurrence of strand breakage and wire breakage after a wire is cut by the edges and corners.
Drawings
FIG. 1 is a schematic sectional view of the preferred embodiment of the present invention.
Fig. 2 is a schematic perspective view of fig. 1.
The codes in the figures are respectively: 1 is the lower plate, 2 is the threaded fastener, 3 is the wire clamping groove, 4 is the short splint, 5 is the radius, 6 is the wire.
Detailed Description
The present invention is not limited by the following examples, and specific embodiments may be determined according to the technical solutions and practical situations of the present invention.
In the present invention, for convenience of description, the description of the relative positional relationship of the components is described according to the layout pattern of fig. 1 of the specification, such as: the positional relationship of front, rear, upper, lower, left, right, etc. is determined in accordance with the layout direction of the drawings of the specification.
The utility model is further described with reference to the following examples and figures:
as shown in the attached drawings 1 and 2, the abrasion-proof parallel groove clamp comprises a lower clamp plate 1, an upper clamp plate and a threaded fastener 2, wherein the upper clamp plate is arranged above the lower clamp plate 1, and the lower clamp plate 1 and the upper clamp plate are fixedly installed together through the threaded fastener 2; two arc-shaped lower grooves with upward openings are arranged in the middle of the upper side of the lower clamping plate 1 at the front and back intervals, an arc-shaped upper groove with a downward opening is arranged on the lower side of the upper clamping plate corresponding to each lower groove, each lower groove and the corresponding upper groove form a wire clamping groove 3, and rounding 5 are arranged on the upper clamping plate corresponding to the left end and the right end of each wire clamping groove 3 and the lower clamping plate 1. The threaded fastener 2 is a bolt, a nut, a flat spring washer and the like which are well known in the prior art center according to requirements; the radius 5 is a fillet in the prior art, and the radius 5 can completely remove the vertical edge at the wire inlet and outlet position of the parallel groove clamp, and can effectively prevent the wire 6 from being broken after being cut and worn by the vertical edge.
The anti-abrasion parallel groove clamp can be further optimized or/and improved according to actual requirements:
as shown in fig. 1 and 2, the upper clamping plate comprises at least two short clamping plates 4 which are arranged at intervals left and right. The arrangement is mainly that the stress of the wires 6 in the wire clamping groove 3 can be more balanced after the upper clamping plate is divided into the plurality of short clamping plates 4, and the crimping effect is more reliable.
As shown in fig. 1 and 2, the left end and the right end of the short clamping plate 4 corresponding to each wire clamping groove 3 are provided with rounding circles 5. The arrangement can ensure that the short splint 4 has interchangeability, and is more convenient to process, replace or maintain.
The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect, and unnecessary technical features can be increased or decreased according to actual needs to meet the requirements of different situations.
