Abstract
The utility model relates to a be used for the shockproof resistant fastener that breaks at centre gripping wire terminal on power transmission line. The shell 1 of the cable clamp is two half pipes which can be buckled together and hinged at one side, and the other side is screwed by a bolt. Two rubber semicircular rings 2 and 5 are arranged at two ends in the shell, two opposite wedge-shaped pressing blocks 3 are arranged at the middle part, and pressing grooves 4 matched with the conducting wires are formed in the bottom planes of the wedge-shaped pressing blocks. When the wire clamp is used, the wire clamp is connected to a line tower through the hanging plate 6, the two shells are clamped after the wire terminal passes through the middle of the wire clamp, the wedge-shaped pressing block can clamp the wire, and the rubber rings at the two ends can protect the wire and delay breakage.
Description
Technical field: the utility model is a kind of electric power equipment, promptly a kind of vibrationproof strain clamp that is applicable to that the transmission line wire terminal is fixing.
Background technology:, need fix the lead terminal with a kind of device in the lead terminal of transmission line.Present fixture has a lot, but belongs to rigid fastening mostly.Because lead is among the vibration constantly, rigid fixing makes lead occur losing easily, also circuit pylon and connector caused damage simultaneously.
Summary of the invention: develop and a kind ofly can clamp the terminal lead, can cushion the vibrationproof strain clamp of conductor vibration again.The characteristics of this wire clamp are: the shell of this wire clamp is that two fans can be to the hard shell that is buckled together, and a side of two housings is hinged by pin uranium and hinged plate, and two fan shells can carry out opening and closing movement around bearing pin; On the opening of opposite side, be provided with and can wear the clamping plate that connects by bolt, when closing, can two shells be clamped by bolt; In the inboard of two fan housings, two ends are the semi-cylindrical cavity, respectively adorn an elasticity semicircular ring in the cavity, and the middle part is one and carves the shape cavity, a hard respectively is housed in the cavity carves the shape briquetting; It is big to carve shape briquetting one end, and an end is little, has one on the bottom surface from the big small end inner groovy of holding, and two fans are after housings close, the semicircular ring at two ends and middle part carve piece when relative, middlely form a through hole that matches with the lead profile.
Said surface of carving the indent on the shape briquetting bottom surface is provided with concavo-convex ring.
The said shape briquetting of carving, its baseplane have vertical semicircle indent indent, and its both sides are the plane perpendicular with the bottom surface, and upper surface is an arc surface.
Said wedge briquetting, its outer surface are the semicircle conical surface.
The said shape briquetting of carving, its cross section is a rectangle, vertical section is a right-angled triangle.
The elasticity semicircular ring at said cased side two ends, with the contact-making surface of shell on be provided with the boss that matches with shrinkage pool on the shell.
The vibrationproof strain clamp that adopts such scheme to make, lead can insert from the small end of carving the shape briquetting, when drawing outside the lead, carves the displacement immediately of shape briquetting and with its clamping.Like this, promptly allow lead that certain pull is arranged, can clamp lead again.Because the wire clamp two ends all are provided with the elasticity semicircular ring, can prevent losing of lead, thereby reach the vibrationproof strain insulator, the purpose of fixing cord terminal.
Accompanying drawing is introduced: Fig. 1 is a front view of the present utility model, and Fig. 2 is its left view, and Fig. 3 is its vertical view.
Among the figure as seen: shell 1, elasticity semicircular ring 2 is carved shape briquetting 3, indent 4, elasticity semicircular ring 5, hanging plate 6, hinged plate 7, bearing pin 8, clamping plate 9, bolt 10.
Execution mode:
First kind: as shown in the figure, but the shell 1 of this wire clamp is the semicanal of two make-ups, is hinged by connecting plate 7 and bearing pin 8 in the one side.Passing two relative clamping plates 9 at opposite side by bolt 10 can clamp two fan shells, and respectively there are an elasticity semicircular ring 3 and 5 in two ends in the shell, and available rubber is made, and the back side is provided with boss, and installation matches with shrinkage pool on the shell.The middle part has a hard to carve shape briquetting 3 in the shell, and having a cross section on the baseplane of briquetting 3 is semicircular indent 4, is provided with the concavo-convex ring of helical form in the indent 4.But two fan shell foldings, when closing, the semicircular ring 3 at two ends with 5 just to having become annulus, two carve the shape briquetting also to together, the centre is a clamp hole by 4 pairs of one-tenth of indent.Wire clamp hangs over by hanging plate 6 on the shaft tower of circuit during use, can earlier two shells be opened, and the lead terminal is put into indent 4, shell is shut again, and tights a bolt 10 can clamp lead.Concavo-convex ring and conductive line surfaces in the indent match, and when the lead interpolation, it is inoperative to carve the shape briquetting, allow to insert, and when drawing outside the lead, carve the shape briquetting and clamp immediately, and prevent the lead displacement.The rubber semicircular ring 3 at wire clamp two and 5 contacts with lead, can delay losing of lead.As seen from the figure, the shape of this wedge shape briquetting 3, it is cross-section near rectangle, and just fluted on the baseplane, upper surface is a cambered surface, and both ends of the surface are the plane vertical with the bottom surface.
Second kind: will carve shape briquetting 3 and make two semicircle frustums, and also on the baseplane, have indent.
The third: the cross section of carving shape briquetting 3 is a rectangle, and its vertical section is a right-angled triangle, removes the angle that a bottom surface is become with upper surface, forms one one end height, and an end is low, and the quadrangle that the top is oblique also can reach the purpose of clamping.
