Abstract
The utility model relates to a combination type contact assembly, and especially is a double-based combination type contact assembly. The double-based combination type contact assembly of the utility model comprises a copper base and contact material. The contact material is arranged at the top of the copper base. Thereof, the contact material is divided into two zones of a front zone and a back zone; the front zone is arc-proof contact material, and the back zone is high conductivity contact material. Because the switching zone of the utility model adopts the material with good performance of arc-extincted and arc-proof, the contact material can tolerate the electroerosion created by the intensive electric arc in the switching process so as to greatly increase the electrical durability. The service life of the electric appliance can be increased. However, in the normal closed zone, that is the current-carrying zone still uses the material with small electric resistivity but favorable electric performance, the electric appliance of adopting the rated current for a long time can be ensured without creating the overhigh temperature rise. This can commendably solves the problem of ideally realizing the switching function and the current-carrying function on the same contact.
Description
Technical field
The utility model relates to a kind of combined contact, the combined contact assembly of especially a kind of double-basis.
Background technology
In the course of the work, connect the contact assembly that forms is mainly being undertaken connecting and disconnecting electrical equipment in electrical equipment effect with the copper pedestal by contact material.
In the high-power electric appliance of certain model, such contact assembly is generally paired use, its connection process is: contact at the front end position earlier, then keep two contact assemblies all the time under the state of contact camber working face along contact be rolled into the bottom contact mutually, enter normally off, be the circuit on-state, finish a connection.The disconnection process of electrical equipment is the reverse process of connection process.Contact assembly can produce strong electric arc when carrying out the break-make of circuit, thereby to contact, mainly is that the break-make district produces very strong electroerosion, causes reduce the useful life of whole electrical equipment thereby reduce its electric life.Therefore, just must have very strong blow-out and anti-orphan's property as contact material.And, therefore require contact material resistivity very little again in case after entering normally closed on-state, its function then is transformed into the current-carrying effect, have good electric conductivity and low and stable contact resistance.Particularly the electric current that it passes through in high-power electric appliance is very big, if not having these merits will produce very big temperature rise, this is unallowed.But still do not have any material at present and can have above two kinds of merits simultaneously.How to solve this contradiction? one of method is exactly to adopt main contact and two grades of contacts of arcing contact, and main contact is mainly used to current-carrying, and arcing contact then is mainly used to carry out the connection and the disjunction of electric current.Contact system as the DW16 circuit breaker adopts this mode exactly.But some electrical equipment is not because the restriction of overall space allows to adopt two grades of contacts, carries out current-carrying and can only promptly carry out break-make on a pair of contact.Because general current-carrying is the function of tonic chord of contact system, generally all be inclined to the little and material that conducts electricity very well of selection resistivity selecting for use of material, but its blow-out is relative with pitch-durable performance relatively poor, so just the break-make district very easily appears owing to thereby electroerosion makes the situation of its electric life of contact very fast damage the reduction, the useful life of also just having reduced whole electrical equipment simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of double-basis combined contact assembly, and the combined contact assembly of this double-basis not only has very strong blow-out and are-tight property and has good electric conductivity and low and stable contact resistance.
The purpose of this utility model is achieved in that
The combined contact assembly of double-basis comprises copper pedestal and contact material, and contact material is positioned at the top of copper pedestal, wherein: two districts before and after contact material is divided into, the proparea is are-tight contact material, the back zone is the high conductivity contact material.
The combined contact assembly of double-basis, wherein: the copper pedestal is made up of two copper bases, and two vertical connections of copper base are L-shaped, and contact material is positioned at the top of a copper base, and the perforation of going up of another piece copper base is provided with circular hole.
The combined contact assembly of double-basis, wherein: the spademan platform is set up in the both sides of copper pedestal.Being connected as a single entity of spademan platform and copper pedestal.
The utility model is because the break-make district has selected blow-out and pitch-durable performance excellent material for use, thereby the electroerosion that makes contact material can tolerate the strong electric arc that produces in the make and break process improves electric life greatly, has promptly improved the useful life of electrical equipment.And in normally closed district, promptly the current-carrying district still uses resistivity little and the material that conducts electricity very well guarantees that electrical equipment does not produce too high temperature rise for a long time by rated current.So just solved the problem that realizes break-make and two functions of current-carrying on same contact coideal ground well.

Reference numeral: copper pedestal 1, are-tight contact material 2, high conductivity contact material 3, circular hole 4, spademan platform 5.
Embodiment
The combined contact assembly of double-basis comprises copper pedestal 1 and contact material, and contact material is positioned at the top of copper pedestal 1, wherein: two districts before and after contact material is divided into, the proparea is are-tight contact material 2, the back zone is a high conductivity contact material 3.
The utility model makes contact material can tolerate the electroerosion of the strong electric arc that produces in the make and break process because the break-make district has selected blow-out and the good are-tight contact material 2 of pitch-durable performance for use, thus the useful life of improving electrical equipment greatly.And in normally closed district, promptly the current-carrying district still uses resistivity little and the high conductivity contact material 3 that conducts electricity very well guarantees that electrical equipment does not produce too high temperature rise for a long time by rated current.So just solved the problem that realizes break-make and two functions of current-carrying on same contact coideal ground well.
The combined contact assembly of double-basis, wherein: copper pedestal 1 is made up of two copper bases, and two vertical connections of copper base are L-shaped, and contact material is positioned at the top of a copper base, and the perforation of going up of another piece copper base is provided with circular hole 4.All the other are with embodiment 1.
The combined contact assembly of double-basis, wherein: spademan platform 5 is set up in the both sides of copper pedestal 1, and spademan platform 5 is connected as a single entity with copper pedestal 1.All the other are with embodiment 1.
Set up spademan platform 5, make the width of copper pedestal 1 and spademan platform 5 surpass contact material, be convenient to mould is placed on the spademan platform 5.Be convenient to the are-tight contact material 2 and the high conductivity contact material 3 of unlike material are welded on the copper pedestal 1.
