Abstract
The utility model provides a heavy load current flexible joint device, which comprises at least a flexible joint body. The utility model is characterized in that the flexible joint body has a multi-layer structure formed by a plurality of overlapped metal foil strips <1>, the two ends <3> of the multi-layer structure are connected through pressure welding, and the middle <2> is bent and kept a free-layered state. One of the assemblage structures is that the two ends of the multi-layer structure are respectively welded with a connecting plate; and the other assemblage structure is that the screw holes for assembly are directly arranged in a pressure welding connecting area of the two ends of the multi-layer structure. The utility model has the advantages that the design is novel, the structure is skillful, and the utility model not only has excellent electric conductivity but also has excellent thermal compensation capability and vibration isolation effect.
Description
The utility model relates to a kind of connector of conductive contact, is specifically related to a kind of metal forming soft connection device of big load current.
On the equipment of industries such as metallurgy, chemical industry, electric power, electronics, carry out its specific (special) requirements that is electrically connected with of big load current.Generally speaking, high-quality to finish the electrical connection of big load current, the one, consider the electric conductivity problem; The 2nd, consider the problem on deformation of expanding with heat and contract with cold; The 3rd, consider to vibrate isolating problem; The 4th, consider safety problem.In the prior art, the electrical connection of big load current often adopts braid over braid to be flexible coupling, this flexible connection structure is to be woven into the soft copper strips of quality with many copper free wires, adds upper junction plate again at the copper strips two ends and constitutes, and its advantage is easy for installation, good heat dissipation effect, the thermal compensation ability is strong, but that shortcoming is a volume is big, and electric conductivity is undesirable, poor rigidity, reliability are not high.
The utility model purpose provides that a kind of electric conductivity is good, the big load current soft connection device of reliable operation, long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of big load current soft connection device, at least constitute by the main body that is flexible coupling, the described main body that is flexible coupling is the sandwich construction that is formed by stacking with chaff, the two ends pressure welding of sandwich construction connects, the centre is bending and keeps the free layer assignment state, and the two ends of sandwich construction are respectively equipped with mounting structure.
In the technique scheme, described " main body is flexible coupling " is meant a kind of upperseat concept of the primary structure that is flexible coupling.Described " chaff " is meant a kind of laminar metallic object, also can be tinsel, sheet metal or bonding jumper.Described " metal " generally adopts electric conductivity preferred metal such as copper, aluminium.Described " free layer assignment state " is meant the nature after a plurality of chaff stacks.
In the technique scheme, described mounting structure can be following two kinds of situations:
1, at the two ends of sandwich construction a connecting plate is set respectively, connecting plate is welded on respectively on the end face of sandwich construction.This situation is to connect by the connecting plate transition.
2, the screw hole that usefulness will be installed directly is opened in the pressure welding join domain at sandwich construction two ends.
In the technique scheme, be bending in the middle of the described sandwich construction, concrete curved shape can be decided according to the actual requirements, and generally speaking, can be bending, wave structure or domes etc.
The utility model operation principle is: conductive metal substrate is decomposed into multilayer superposed metal chaff, utilizes chaff to be easy to generate the flexural deformation principle, make a kind of being flexible coupling of excellent conductive capability that have.Adopt the natural air cooling in the work.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the utility model utilizes chaff to be easy to generate diastrophic principle, many chaffs are formed the conductivity integral that is flexible coupling by multilayer stack, its technical conceive novelty designs ingeniously, has novelty and creativeness.
2, the utility model can pass through big electric current (such as 36000A) after installing, and makes vibration obtain isolating simultaneously again, also can not cause the joint pine and jeopardize device security because of the two ends swollen shrinkage of heat that is flexible coupling.Therefore both had good electric conductivity, had good thermal compensation ability and vibration isolation effect again.
3, adopt the natural air cooling in the utility model work, have certain rigidity, and easy for installation.
4, the utility model is fit to make being flexible coupling of efficient big load current, and maximum secting area can be 40000mm
