Abstract
The utility model relates to a low voltage apparatus fitting, in particular to a flakiness-shaped contact with a mesh decorative pattern welding surface. The flakiness-shaped contact with the mesh decorative pattern welding surface comprises the welding surface with a mesh decorative pattern and a working face which is plane or spherical. Specifically, the welding surface is provided with the mesh decorative pattern, and the working face is plane or spherical. The welding surface is pressed and machined through a stamp die with the mesh decorative pattern or is rolled through a molding roller with the decorative pattern. Mesh holes are in a diamond shape, the mesh decorative pattern is a decorative pattern with acute angles of the diamond shape from 20 degrees to 70 degrees and obtuse angles from 110 degrees to160 degrees. Welding efficiency is enabled to be improved, and welding quality is good. Anti-tensioning strength is high after welding, and welding brazed rate can reach over 98%. After a contact bridge assembly of the contact is installed, rising of temperature can be guaranteed to prolong the service life in the process of working. Welding automation can be achieved.
Description
Technical field
The utility model relates to a kind of low-voltage electrical apparatus accessory, refers to that specifically a kind of solder side has the sheet contact of netted decorative pattern.
Background technology
The sheet contact is realized being connected with tactile bridge spare by electric resistance welding or soldering at present.The firm degree of welding just represents in order to ratio of brazing area.Therefore just there is the problem of ratio of brazing area height at weld interface, the sheet contact solder side of real world applications welding is the plane, when confirming welding operation, practice can not contact (contact solder side and tactile bridge welding junction) fully between two planes, so far the inequality of being heated can appear during weld heating, have loose contact or sealing room, blind area and pore between contact solder side and tactile bridge welding junction, when making expanded by heating, gas can't be got rid of.Cause not prison welding or do not weld and fuse together.Ratio of brazing area is descended, cause after the installation of contact and tactile axle assemble that temperature rise can not be guaranteed when working, electrical equipment premature failure or security incident occurs.Automatic welding None-identified when having again solder side and working face to be all the plane.
The utility model content
The purpose of this utility model is defects and the deficiency that exists in order to overcome prior art, provide a kind of and be easy to electric resistance welding and soldering and connect that ratio of brazing area is high, welding tensile strength is large, a kind of solder side that the contact assembly temperature rise is guaranteed and automatic welding can be identified when work has the sheet contact of netted decorative pattern.
For achieving the above object, the concrete technical scheme that the utility model is taked is:
A kind of solder side has the sheet contact of netted decorative pattern to include the solder side of netted decorative pattern and the working face of plane or sphere.Refer to that specifically the netted mesh of solder side is shaped as rhombus, the acute angle of rhombus is that 20 °～70 °, obtuse angle are the netted decorative pattern of 110 °～160 °, and working face is plane or sphere.Solder side is in order to the punch die press process of netted decorative pattern or use with the molding roller of netted decorative pattern is rolling and form.
The beneficial effects of the utility model are: solder side is printed on netted decorative pattern makes welding efficiency high, and welding quality is good.During welding, reticulate pattern moment can discharge gas, and the welding ratio of brazing area can be reached more than 98%.Tensile strength after welding obviously increases.Make after contact probe axle assemble installation at work that temperature rise is guaranteed, working life is extended.And can realize Automation of Welding.
