Description
Technical field
The utility model relates to a kind of device clamp, be specifically related to a kind of moment device clamp.
Background technology
Device clamp is widely used in bus leading and rolls off the production line with electric equipment (as transformer, circuit breaker, instrument transformer, isolating switch, wall bushing etc.) outlet terminal connects, according to the installation and application of device clamp, be divided into screw bolt-type device clamp and compression-type device clamp, device clamp is developed to the present moment interconnection technique of determining moment torsion from the crimp technology of traditional pressing mold confined pressure, though device clamp is little, but it is very important that it acts in electrical system, because of its special operational environment, the increase of its contact resistance is the problem generally facing, contact resistance increase easily causes following threat: the increase of (1) contact resistance can cause the short circuit current of circuit to reduce, extend the operate time of short-circuit protection, or the action of obstruction short-circuit protection, greatly threaten the fail safe of electric power system, (2) in actual motion is safeguarded, the fracture of cuprum aluminum transition joint is very general, particularly polluting heavy district, for example in the group of cities of the Delta of the Pearl River, monthly has repairing for several times when quantity is many.
In copper aluminium welding process, copper aluminium electrode potential difference is large, the too high corrosion that easily causes aluminium of welding temperature in addition, and the brittle substance that during welding, the counterdiffusion of copper aluminium phase generates makes clamped nipple unstable properties, has reduced terminal corrosion resistance; The external force impact of cuprum aluminum transition joint is mainly from two aspects, one is the stressed of when construction, another is the tractive effort of wire in day-to-day operation, these adverse effects will directly cause shorten the useful life of terminal in service, accelerated the process of fracture, so prevent that the oxidation of cuprum aluminum transition joint, fracture from being current device wire clamp technical field urgent problem, at present device clamp on the market generally adopts presses, confined pressure technology, electric property and torsion performance can not be taken into account completely, and installation inconvenience and versatility are not high.
Utility model content
For the deficiency existing in prior art, the utility model object is to be to provide a kind of moment device clamp, and inserted sheet design is simple in structure, model is simplified, corrosion resistance is strong, easy for installation, has taken into account electric property and torsion performance, inside there is grid tube wall, enlarge active surface, wire clamp stable performance, overload capacity and the useful life of having improved wire clamp.
To achieve these goals, the utility model is to realize by the following technical solutions: a kind of moment device clamp, comprise wire pressing block, connect main body and line ball nut, connect in main body and be provided with wire pressing block, projection in wire pressing block be connected main body in groove fit setting, the one end that connects main body is provided with flat connecting plate, and the perforate connecting in main body is connected with line ball nut thread.
As preferably, one end of described wire pressing block is provided with center positioning hole, and the inner side of wire pressing block is provided with striped wall, and the length of wire pressing block is less than the length that connects body cylindrical shape wire barrel.
As preferably, described line ball nut adopts M16 tooth torque nut.
As preferably, on described flat connecting plate, be provided with wiring hole.
As preferably, described wire pressing block, connect main body, line ball nut all adopts aluminum material.
The beneficial effects of the utility model: with respect to pressing of generally adopting on the market, confined pressure technology, moment device clamp has been taken into account electric property and torsion performance, inserted sheet design, simple in structure, easy for installation, wire clamp stable performance, corrosion resistance is strong, improve overload capacity and the useful life of wire clamp, reduced energy loss.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;
Fig. 1 is decomposition texture schematic diagram of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1, this embodiment is by the following technical solutions: a kind of moment device clamp, comprise wire pressing block 1, connect main body 2 and line ball nut 3, connect in main body 2 and be provided with wire pressing block 1, projection 13 in wire pressing block 1 is equipped with the groove 23 in being connected main body 2, the one end that connects main body 2 is provided with flat connecting plate 21, the perforate connecting in main body 2 is threaded with line ball nut 3, line ball nut 3 adopts torque nut design, the concave design of nut contact-making surface contributes to increase torsion grip, torsion is constant, need not special tool(s), and easy for installation; Connect main body 2 tube walls and be provided with netted in length and breadth groove, greatly increased effective contact area, be more easy to control installation site.
One end of it should be noted that described wire pressing block 1 is provided with center positioning hole 11, and center positioning hole 11 helps wire placed in the middle, the inner side of wire pressing block 1 is provided with striped wall 12,, contributing to fixing cord, the length of wire pressing block 1 is less than the length that connects main body 2 cylindric wire barrels.
It should be noted that described line ball nut 3 adopts M16 tooth torque nut, the constant pressure that line ball nut 3 guarantees between wire and wire clamp, guarantees that good electrical connects.
