Description

The connector that lead and transformer are lifted one's head
Technical field
The utility model relates to the connector of electric power system, the connector that particularly a kind of lead and transformer are lifted one's head.
Background technology
At present; In electric power system, also be provided with and be specifically designed to lead is connected usefulness with transformer connector; Still adopt common lead and conductor jointer; Lower plate, an outside of circular arc flange were provided with interior concaved circular cambered surface in this connector was provided with by both sides, and the inboard is that first train wheel bridge of a breach cylinder, an outside are provided with interior concaved circular cambered surface, and the inboard is that second train wheel bridge and the fastening bolt on a face of cylinder that cooperates with the first train wheel bridge breach cylinder formed.This connector only is fit to lead and is connected with lead, is connected with transformer is lifted one's head and be used for lead, and lifting one's head owing to transformer is a complete screw rod; Under the interior concaved circular cambered surface of the circular arc in-flanges of lower plate and train wheel bridge clamps, can not produce distortion, and train wheel bridge has only part to contact with the arc surface of lower plate to the clamping of lifting one's head, and skids easily; Folder is not fastening again; Cause heating, come off and wait the human accident generation, often will keep in repair; Influence efficiency of construction and usefulness, this is the weak point of prior art existence just.
The utility model content
The purpose of the utility model is to solve the above-mentioned defective that existing connector exists, and provides a kind of gripping performance good, the connector that lead that is not easy to get loose and transformer are lifted one's head.
Above-mentioned task realizes by this way: the connector that a kind of lead and transformer are lifted one's head; Include lower plate, first train wheel bridge, second train wheel bridge and fastening bolt; Its improvements are: the side that lower plate is relative with first train wheel bridge be one with the lower plate disjunctor, but the terminal reel that is not connected, its endoporus with lower plate be one tangent with lower plate and lift one's head the screwed hole that is connected with transformer; The reel end thickness is 1.5~3.0 millimeters; The thickness of reel outside Lower Half is identical with lower plate thickness, and the circular arc that is connected to that its first half outer rim to reel is terminal connects, and the interior concaved circular cambered surface in first train wheel bridge outside is connected with the exterior arc surface of reel.
The utility model can take following measure further perfect:
Upper end at the inboard breach cylinder of first train wheel bridge is provided with a platform, can prevent that behind last jack panel first train wheel bridge from sliding, and guarantees that two train wheel bridges are lifted one's head to transformer and the chucking power of lead.
On the inner arc surface of the lower plate and the second train wheel bridge corresponding position, be provided with some vertical profile of tooth fins, can increase frictional force, make the lead after the clamping be not easy to come off lead.
Have a radius in reel upper end and be 1~1.5 millimeter semicircle longitudinal fluting, help reel to produce slight deformation, improve chucking power in stressed back.
The thickness of described lower plate is not less than 7 millimeters at least, to improve the anti-ability of fractureing of lower plate.
The utility model is to use like this: earlier the lower plate of this connector screw thread through endoporus was threaded on lifting one's head of transformer during use; Then with lead placement in the interior concaved circular cambered surface of the lower plate other end; Put into first train wheel bridge and second train wheel bridge toward lower plate again; Load onto fastening bolt, make its both sides that lead and transformer are lifted one's head to clamp just can with fastening first train wheel bridge and second train wheel bridge are compressed of nut.
The beneficial effect of the utility model is following: lift one's head the screwed hole that is threaded because the reel endoporus of this connector is one with transformer, be not easy after the assembling to get loose.Because the reel first half to end is a cylindrical shell that thickness reduces gradually, receive the slight distortion of lateral thrust effect meeting generation of first train wheel bridge after fastening in addition, make it lift one's head the more firm of clamping transformer.Have again; This connector is provided with a platform in the upper end of the breach cylinder of first train wheel bridge; Prevented that first train wheel bridge from sliding, and on the inner arc surface of lower plate and lead bare terminal end, be provided with some vertical profile of tooth fins, improved the chucking power of this connector greatly.Therefore, it is good that this connector has chucking power, is not easy to become flexible, and advantage easy to use can be removed the thermal boundary accident of the bad appearance of clamping effectively, improves construction quality and efficient, increases the service life.
Description of drawings
Below in conjunction with accompanying drawing the structure of the utility model is done further to describe.
The front view of the connector that Fig. 1 lifts one's head for a kind of lead and transformer.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
With reference to Fig. 1~Fig. 2; The connector that a kind of lead and transformer are lifted one's head; Include lower plate 1, the first train wheel bridge 2, second train wheel bridge 3 and fastening bolt 4, it is characterized in that: lower plate 1 and first train wheel bridge, 2 relative sides be one with lower plate 1 disjunctor; But terminal and lower plate 1 unconnected reel 5; Its endoporus 6 be one tangent with lower plate 1 and lift one's head the screwed hole that is connected with transformer, the thickness of the end of described reel 5 is 1.5~3.0 millimeters, the thickness of reel 5 outside Lower Halves is identical with lower plate 1 thickness; Its first half outer rim to reel 5 terminal circular arcs that are connected to connect, and the interior concaved circular cambered surface in first train wheel bridge, 2 outsides is connected with the exterior arc surface of reel 5.
