Abstract
The invention discloses a tension-resistance wire clamp which comprises a wire clamp body, a steel anchor and a drainage tube. A U-shaped drainage plate with an internally-formed groove is arranged at the designated position of the wire clamp body, the drainage plate is provided with a forked clamping opening, a panel is arranged at one end of the drainage tube, a protrusion corresponding to the groove of the drainage plate is arranged in the panel, a hollow blind tube is arranged at one end of the panel, and a wire jumper can be arranged in the hollow blind tube. A lock hole is formed in the U-shaped drainage plate, a corresponding lock hole is formed in the segment where the drainage tube is matched with the drainage plate, when the drainage tube is inserted into the drainage plate, the drainage tube is locked by a bolt, and good locking is obtained. According to the tension-resistance wire clamp, the drainage tube for containing the wire jumper and the drainage plate have the excellent contact area, the stability of current transmission is ensured, the tension-resistance wire clamp is particularly suitable for being used for mutual connection between a wire on an iron tower and the wire jumper, the higher current-carrying capacity is met, the protrusion and the groove which are mutually matched are arranged at the position where the drainage plate is locked with the drainage tube, the matching strength of the drainage plate and the drainage tube is increased, and the tension-resistance wire clamp can bear stronger wind.
Description
Technical field
The present invention relates to a kind of strain clamp, belong to the power circuit assorted golden tool.
Background technology
Overhead transmission line is by strain tower the time, need to be fixed on the strain insulator of strain tower, and use wire jumper to carry out drainage to complete the leap connection of overhead transmission line to overhead transmission line, at this moment need to use strain clamp to complete fixing between overhead transmission line and strain insulator, and to the drainage of overhead transmission line.Strain clamp comprises strain clamp body, steel anchor, drainage plate and drainage tube.Strain clamp is mainly to be inserted in the strain clamp body by the steel core by overhead transmission line to the drainage of overhead transmission line, and the other end of the drainage plate that an end is combined with the strain clamp body is connected with drainage tube, and drainage tube is connected to realize with wire jumper.
At present, drainage plate one end shape is designed to sheet, coordinate an end also drainage tube in the form of sheets form to paste and touch sealed connection, i.e. the drainage of drainage plate and drainage tube is single contact-making surface drainage way.The voltage transmitted due to overhead transmission line is more and more higher, and the ampacity of single contact-making surface drainage can't meet the demands.
Summary of the invention
In view of this, the object of the invention is to provide a kind of strain clamp, to meet higher ampacity requirement.Intensity is higher.
For achieving the above object, the invention provides following technical scheme: a kind of strain clamp, comprise a wire clip body, a steel anchor and a drainage tube, it is characterized in that described wire clip body arranges the U-shaped drainage plate of built-in groove in select location, described drainage plate has a jag jaws; One end of described drainage tube is for having the projection corresponding with the drainage plate groove in flat board, flat board, and an end is the hollow blind pipe, in described hollow blind pipe, a wire jumper can be set.
Further, described U-shaped drainage plate is welded on the strain clamp body.
Further, on described U-shaped drainage plate, lockhole is set, drainage tube arranges corresponding lockhole with the drainage plate section of cooperation, when drainage tube inserts drainage plate, by the bolt locking, is obtained good sealed.
Compared with prior art, strain clamp of the present invention settles drainage tube and the drainage plate of wire jumper to have good contact area, guarantee the stability of current delivery, be particularly suitable for steel tower upper conductor and wire jumper as interconnecting use, meet higher ampacity requirement, the sealed place of drainage plate and drainage tube is provided with projection and the groove cooperatively interacted, and the strength increase that coordinates of drainage plate and drainage tube, can make the strain insulator line bear larger wind-force.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The A-A profile that Fig. 2 is Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further described.
As depicted in figs. 1 and 2, strain clamp of the present invention, comprise a wire clip body 2, a steel anchor 4 and a drainage tube 5, it is characterized in that described wire clip body 2 arranges the U-shaped drainage plate 3 of built-in groove in select location, and described drainage plate 3 has a jag jaws; Described drainage tube 5 one ends are for having the projection corresponding with drainage plate 3 grooves in flat board, flat board, and an end is the hollow blind pipe, in described hollow blind pipe, a wire jumper can be set.
Described U-shaped drainage plate 3 is welded in or directly is cast on strain clamp body 2.On described U-shaped drainage plate 3, lockhole is set, drainage tube 5 arranges corresponding lockhole with drainage plate 3 sections of cooperation, when drainage tube 5 inserts drainage plate 3, by the bolt locking, is obtained good sealed.
Technical scheme of the present invention is not limited to the restriction of above-mentioned specific embodiment, and the technology distortion that every technical scheme according to the present invention is made, within all falling into protection scope of the present invention.
