Description
Technical field
The present invention relates to a kind of electrical contact, in particular to a kind of tap switch electrical contact.
Background technique
The contact of switch currently used in the market is horizontal bridge architecture, and the contact of the structure type is in switch connection
When, since movable feeler lever moves vertically with moving contact with respect to static contact, so that moving contact brings vertical impact to static contact, in this way
The spring formed by impact force easily causes to switch the secondary bounce arcing in making process, influences the electricity of switch with regard to bigger
The gas service life.
Summary of the invention
The object of the invention is that it is simple to provide a kind of structure, easy for installation, tap switch electricity consumption with long service life
Contact.
To achieve the goals above, the technical solution adopted by the present invention is that such: tap switch electricity consumption touching of the invention
Head, including contact body, the contact body include matrix, and contact is provided on matrix, and the contact top surface is arc-shaped, base
Body bottom is provided with mounting portion, and matcoveredn is arranged in the contact body surface.
Preferably, described matrix top and bottom are respectively arranged with thread groove, contact and mounting portion pass through screw thread and base
Body connection.
Preferably, the protective layer is made of high conductive material.
Preferably, the mounting portion bottom surface is provided with a groove.
Compared with the prior art, the advantages of the present invention are as follows: the configuration of the present invention is simple, easy for installation, long service life, touching
Head is used with mounting portion with matrix and matrix and is threadedly coupled, and contact resistance is small, and electric energy loss is low；Height is provided in contact body to lead
Electric layer extends the service life of electrical contact, reduces costs.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
Referring to Fig. 1, tap switch electrical contact of the invention, including contact body, the contact body include matrix, base
Be provided with contact on body, the contact top surface be it is arc-shaped, base bottom is provided with mounting portion, the contact body surface setting
Matcoveredn, described matrix top and bottom are respectively arranged with thread groove, contact and mounting portion and are connect by screw thread with matrix, institute
It states protective layer to be made of high conductive material, the mounting portion bottom surface is provided with a groove.
The configuration of the present invention is simple, easy for installation, long service life, contact and matrix and matrix and mounting portion are connected using screw thread
It connects, contact resistance is small, and electric energy loss is low；It is provided with high connductivity layer in contact body, extends the service life of electrical contact, reduces
Cost.
