Abstract
The utility model provides a kind of solder contacts for switching seesaw, including seesaw and contact, described seesaw has contact weld part, described contact weld part includes upper surface and lower solder side, described contact includes solder side and contact lower surface on contact, is welded and fixed between described contact and seesaw by the lower solder side of solder side on contact and contact weld part as integral type structure.Solder side has pedestal on described contact.The lower solder side of described contact weld part is plane.Described pedestal includes big salient point and some small salient points, and big salient point thickness is more than small salient point, and described small salient point is circumferentially positioned on the contact of big salient point periphery on solder side, and the spacing between small salient point is equal.The contact of this product and seesaw are not in contact with gap, being merged completely, the temperature rise that contact be connected generation with seesaw does not have by being welded and fixed as integral type between seesaw and contact, negligible, substantially increase switch service life.
Description
Technical field
The utility model is related to a kind of switch, more particularly to a kind of solder contacts for switching seesaw.
Background technology
Switch seesaw and contact in the market is fixed using riveting, and the problem of existing is fixed in riveting：Contact with
Seesaw is connected, and uses the space between external force crimp, filling seesaw and contact portion.Switch is easy in a state of use
Heating, metalwork object all has expanded by heating, the physical principle of contract on cooling；Seesaw is heated, and is heated between seesaw and contact
Expansion, contract on cooling, the gap between seesaw and contact portion becomes larger；The temperature that gap change is produced greatly is also higher, switch
Seesaw is by current heating, the more high easy soft plastics part of temperature, and temperature rise rise is also easy to produce fire；Expanded by heating, contract on cooling is stuck up
Plate becomes big with contact portion gap, then switch contact resistance becomes big, and temperature rise rise, switch life weakens significantly.
Utility model content
For existing technical deficiency, the utility model provides a kind of solder contacts for switching seesaw.
To achieve these goals, technical solution adopted in the utility model is：A kind of solder contacts for switching seesaw,
Including seesaw and contact, described seesaw has contact weld part, and described contact weld part includes upper surface and lower solder side,
Described contact include contact on solder side and contact lower surface, between described contact and seesaw by solder side on contact with
The lower solder side of contact weld part is welded and fixed as integral type structure.
Solder side has pedestal on described contact.
The lower solder side of described contact weld part is plane.
Described pedestal includes big salient point and some small salient points, and big salient point thickness is more than small salient point, and described is small convex
Point is circumferentially positioned on the contact of big salient point periphery on solder side, and the spacing between small salient point is equal.
The beneficial effects of the utility model：The utility model provide it is a kind of switch seesaw solder contacts, this product touch
Point, by being welded and fixed as integral type, is not in contact with gap, is merged completely with seesaw between seesaw and contact, contact with
The temperature rise that seesaw connection is produced does not have, and can be neglected, substantially increases switch service life.
