Abstract
The utility model relates to a J-shaped parallel groove wire clamp, which comprises two clamp bodies provided with a connecting through hole respectively, the two clamp bodies are connected and buckled by fastening components arranged in the connecting through holes, a cambered surface groove is arranged in one end of each clamp body in a bending way, and the other end of each clamp body is an inclined plane taking a J shape; the cambered surface groove of one clamp body is correspondingly matched with the inclined plane of the other clamp body, thereby forming a wire clamp opening, and the size of the cambered surface grooves of the two clamp bodies can be the same or not, thereby forming a combination and permutation structure of the clamp opening. The J-shaped parallel groove clamp has a reasonable and simple structure; the J-shaped clamp bodies with the cambered surface grooves having different sizes can be combined, permutated and paired, wire clamps with various specifications can be formed by using clamp bodies with fewer specifications, so that the size of the clamp opening is more matchable with the diameter of a wire, and the clamping contact is more sufficient and more reliable; moreover, the J-shaped clamp bodies are arranged in a way that a certain angle is formed between the pressure-bearing direction of the wire and the axis of the fastening components so as to obtain more pressure on the wire, thereby ensuring the stable contact between the wire and the wire clamp.
Description
Technical field: the utility model relates to the lead non-bearing that a kind of power overhead network uses and continues and branch's gold utensil particularly a kind of parallel groove clamp.
Background technology: the gold utensil of the lead that on power overhead network, continues generally adopts parallel groove clamp or wedge type difference wire clamp.Therefore wedge type difference wire clamp is owing to cooperates closelyr with lead, electric contact performance is stable, but needs special-purpose erecting tools to install when installing, inconvenience, and also wedge core specification is many, and product processing is difficulty relatively, and production efficiency is low, the cost height.It is more convenient to use parallel groove clamp then to install, and does not need special-purpose erecting tools, and produces easily, and cost is low.But the cambered surface groove of the wire clamp mouth of common parallel groove clamp size is fixing; Because same cambered surface groove need cooperate the contact-making surface of lead and lead of multiple different-diameter not enough, and the pressurized direction of lead is identical with the bolt axis; Be that the pressure size is determined by the bolted degree fully; Cause the reliability of electric contact relatively poor relatively, the check of installation quality is also difficult, just can guarantee the safe and reliable of circuit operation so often need a plurality of parallel groove clamps be installed at the place of continuing.
Summary of the invention: to the deficiency of prior art, it is a kind of rational in infrastructure that the utility model provides, and clamping contacts reliable J-shaped parallel groove clamp.
The utility model comprises two clamps that are equipped with connecting through hole, and these two clamps connect fastening through the fastening assembly that places connecting through hole, bends in the end of each clamp to be provided with the cambered surface groove, and the other end is the inclined-plane then, and shape is J-shaped; The cambered surface groove of a clamp and the incline position corresponding matching of another clamp constitute the wire clamp mouth, and the cambered surface groove size in two clamps can be identical or different, constitutes a folder mouthful size combinations arrangement architecture.
The utility model rational in infrastructure simple; Can the J-shaped clamp that the cambered surface groove varies in size be carried out the permutation and combination pairing; Use the clamp of less specification promptly can be combined into the wire clamp of plurality of specifications, the diameter of folder mouthful size and lead is mated more, the clamping contact more fully reliably.And the J-shaped clamp to be designed to be stressed direction and fastening assembly axis of lead angled, promptly the pressure that receives of lead can obtain the bigger pressure to lead like this greater than the suffered stretching resistance of fastening assembly, has guaranteed the contact stabilization of lead and wire clamp.
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Description of drawings: Fig. 1 is the main structure sketch map of embodiment.
Fig. 2 is the front view of clamp.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is the clamping user mode sketch map of Fig. 1.
Embodiment: to shown in Figure 3, two clamps 1 are equipped with connecting through hole 4 like Fig. 1, and these two clamps 1 connect fastening through the fastening assembly that places connecting through hole 4.Interior the bending of one end of each clamp 1 is provided with cambered surface groove 2, and the other end is inclined-plane 3 then, and shape is J-shaped; The cambered surface groove 2 of a clamp 1 constitutes the wire clamp mouths with the inclined-plane of another clamp 13 position corresponding matching, and cambered surface groove 2 sizes in two clamps 1 can be identical or different, constitutes a folder mouthful size combinations arrangement architecture.Fastening assembly generally can adopt bolt 5 and supporting stop nut 6 to form, and stop nut 6 also can be lined with spring washer 7, is fastenedly connected more reliable.Connecting through hole 4 in the clamp 1 can be the track shape hole, so in use is convenient to the position adjustment of clamp 1.
During actual the use, as shown in Figure 4, according to two diameters of wire to be continued; Confirm to select for use wire clamp with the big or small cambered surface groove 2 of suitable correspondence; Lead is put into each self-corresponding wire clamp mouth, tight a bolt 5 and supporting stop nut 6, can install and use easily and fast.Generally the cambered surface groove 2 at clamp 1 also scribbles the conduction grease with 3 places, inclined-plane, so not only contacts better with lead electric, and installs and tightens back conduction grease and partly extruded, and can indicate installment state, and installation quality is checked easily.
In Fig. 4, be easy to find out; Lead receives inclined-plane 3 extruding of clamp 1, and its be stressed direction and bolt 5 axis are angled, according to stressed resolution of vectors; 5 on bolt is stressed much smaller than the lead pressure; The horizontal force that two lead pressure decomposes can offset each other basically, so the less fastening pulling force of bolt 5 usefulness can produce the pressure bigger to lead, and the effect that contacts of enhancing wire clamp and lead.And the lead stress point is longer apart from the arm of force to clamp 1 strong point, and clamp 1 can come to overcome preferably because lead expands with heat and contract with cold to the destruction of wire clamp through the strain of self like this.
