Abstract
The invention discloses a cable clamp device capable of preventing joints from overheating. The cable clamp device is characterized by comprising a pair of cable clamps and a pair of O-shaped guide rings. Each of the cable clamps is provided with a flat connection end having connection fixing holes; the lower surface of one of the cable clamps is provided with a guide slot; and the upper surface of the other cable clamp is provided with a protrusion in clearance fit with the guide slot. The O-shaped guide rings sleeve the connection ends of the two cable clamps side by side and are provided with through holes corresponding to the connection fixing holes of the cable clamps. The O-shaped guide rings sleeve the connection ends of the cable clamps to expand contact areas of the joints, thereby bringing convenience for operators to do installation, facilitating heat dissipation and improving contact tightness; through the guide slot and the protrusion structures arranged on contact surfaces of the cable clamps, the contact area is expanded further, line faults caused by heating of the joints are eliminated, and running reliability of a power grid is improved.
Description
Technical field
The present invention relates to power domain, specifically a kind of wire clamp equipment for eliminating the end of a thread overheat.
Background technology
In this year, as Regional Economic is developed rapidly, people's material and cultural life quality is stepped up, and power consumption is obvious
Increase, and the requirement of the reliability to powering also is significantly improved, to ensure continuous reliable power supply, it is necessary to assure power network power transmission and distribution set
Standby safe and reliable operation, just can guarantee that the continuous reliable power supply of Electricity customers.But, power network equipment for power transmission and distribution quantity is ramped,
Equipment-patrolling and maintenance workload substantially increase；Because power load increases, equipment current-carrying capacity is progressively increased, and connects thin in equipment
The number of stoppages of weak link, also gradually increases；The apparatus connecting unit position defect such as production technology and construction quality, also reduces equipment fortune
Capable reliability.It has been investigated that, electric power transmission line joint area overheat is a big principal element of line fault, and joint
Position overheat is relatively not caused enough mainly due to wire clamp contact surface.
The content of the invention
The present invention is in order to solve the weak point that prior art is present, there is provided a kind of contact area is big, and screw is fixed
And device clamp easy for installation, to eliminate the problem of transmission line of electricity joint area overheat.
The present invention solves technical problem and adopts the following technical scheme that：
A kind of wire clamp equipment for eliminating joint overheat, its design feature is, including a pair of wire clamps and a pair O-shaped water conservancy diversion
Ring, the wire clamp includes a flat connection end with the hole that is connected, wherein the connection end lower surface of a wire clamp is provided with
Guide groove, the upper surface of another wire clamp is provided with the projection coordinated with guide groove gap；Set is pressed in a pair described O-shaped guide rings side by side
Outside two wire clamp connection ends, and it is provided with the through hole in the hole that is connected corresponding to wire clamp.
Design feature of the present invention is also resided in：
The cross section of the guide groove is that the projection is the ball matched with guide groove more than the arc surface of 1/2nd circles
Body.
The cross section of the guide groove is inverted trapezoidal, and the longitudinal direction is trapezoidal with what guide groove matched.
The guide groove is a plurality of, and the projection is identical with guide groove bar number.
The guide groove and projection are for laterally or longitudinally.
Compared with the prior art, the present invention has the beneficial effect that：
In order to increase junction contacts area, the present invention uses a pair O-shaped guide ring casing pressures, the peace of convenient operating personnel
Dress, and advantageous heat dissipation, contact are tight, and pass through wire clamp contact surface and set guide groove and bulge-structure, also further increase contact
Area, eliminates because of line fault caused by wire clamp conductor joint heating, improves operation of power networks reliability.
Guide groove of the present invention is using the arc surface or inverted trapezoidal more than 1/2nd circles, and projection uses corresponding spheroid
With it is trapezoidal when, wire clamp itself can be allowed to carry out upper and lower locked positioning, according to lateral guide groove and projection, then can further laterally
Locked positioning, makes the bolt being arranged on wire clamp be difficult to loosen, it is ensured that the connection end fixing of wire clamp.

Label in figure：11st, wire clamp one；12nd, wire clamp two；101st, 102 connection ends, 1011 be connected hole, 1012 guide grooves,
1013 is raised；2nd, O-shaped guide ring；201st, through hole.
Explanation is further explained to technical solution of the present invention by specific embodiment below in conjunction with accompanying drawing.
Specific embodiment
As illustrated, wire clamp equipment, including wire clamp 1, wire clamp 2 12, a pair O-shaped guide rings 2, wire clamp includes that one is flat
The connection end 101 with the hole 1011 that is connected, the connection end lower surface of wherein wire clamp one is provided with guide groove 1012, wire clamp two
Upper surface is provided with raised 1013 coordinated with guide groove gap；Set is pressed in two wire clamp connection ends to a pair described O-shaped guide rings 2 side by side
Outside 101, and it is provided with the through hole 201 in the hole that is connected corresponding to wire clamp.
The cross section of the guide groove is the arc surface or inverted trapezoidal more than 1/2nd circles, and projection matches with guide groove
Spheroid is trapezoidal, so as to ensure that wire clamp one and wire clamp two can up and down be positioned by guide groove and projection.
During specific implementation, guide groove can be set to a plurality of, can laterally or vertically set, raised identical with guide groove bar number, just
To corresponding with guide groove.
The connected mode of wire clamp equipment is：A pair of guide rings 2 first on set at device clamp connection end, then by wire clamp
One and the matching docking of wire clamp two, it is fixedly connected through the hole that is connected on guide ring through hole and device clamp finally by bolt
Two wire clamps.
