Abstract
The utility model provides a kind of novel switched terminal, including terminal shrapnel and terminal bodies, the afterbody right-angled intersection of the terminal shrapnel and terminal bodies is fixed, the end of the terminal shrapnel is welded with silver layer, the silver layer is bulge-structure, and the silver layer is in the terminal bodies in same level.The switch terminal using by the way of welding silver contact come contact surface caused by solving to rivet is not complete, electric current is unstable the problems such as.The firmness of welding is good, and contact surface is relatively more firm, the loose phenomenon will not be expanded with heat and contract with cold, generated after frequent movement；Contact resistance is stablized, so as to ensure better electric performance stablity；Automatic welding operation can be achieved, reduce operating procedure and operating time, greatly improve work efficiency and production cost.Therefore, the utility model is simple in structure, is readily produced, is highly practical, convenient for being widely popularized on a large scale.
Description
Technical field
The utility model belongs to switching technique field, and in particular to a kind of novel switched terminal.
Background technology
Silver contact is to turn on the critical component with turn-off current, and switch terminal silver contact currently on the market is mostly using riveting
Mode, however contact area is not complete between contact and shrapnel during riveting, according to thermal expansion and contraction principle, connecing when riveting over time
Contacting surface can reduce, and be become higher so as to cause Wen Sheng, can not through safety certification, meanwhile, contact is touched poor with touching bridge joint, and when energization contacts
Resistance can increase, and circuit condition is caused to change；In sound contact frequent breaking and closing after a certain period of time, riveting firmness with
Gap can change, and influence the stabilization of electrical property；In use, arc heat can cause contact material softening under the conditions of high current
And tactile bridge (reed) oxidation, contact performance is caused to reduce.
Utility model content
For technical problem existing in the prior art more than solving, new opened the purpose of this utility model is to provide a kind of
Terminal is closed, the defects of riveting silver contact generates is made up by way of welding silver contact.
A kind of novel switched terminal, including terminal shrapnel and terminal bodies, the afterbody of the terminal shrapnel and terminal bodies
Right-angled intersection is fixed, and the end of the terminal shrapnel is welded with silver layer, and the silver layer is bulge-structure, the silver layer and the end
Sub- main body is in same level.
In a kind of novel switched terminal described in the utility model, the terminal shrapnel with the bulge-structure face of the silver layer
Another side be equipped with groove.
In a kind of novel switched terminal described in the utility model, the afterbody of the terminal shrapnel and terminal bodies passes through weldering
Connect fixation.
Silver layer welding concrete technology flow process be：（1）Terminal shrapnel is welded with silver layer or silver strip on one side,（2）By squeezing
The silver layer reverse side of terminal shrapnel is squeezed into groove by pressure mode, and silver layer face forms protrusion.
Advantageous effect：The utility model provides a kind of novel switched terminal, and the switch terminal is using welding silver contact
Mode is come the problems such as contact surface caused by solving to rivet is not complete, electric current is unstable.The firmness of welding is good, and contact surface is more steady
Gu the loose phenomenon will not be expanded with heat and contract with cold, generated after frequent movement；Contact resistance is stablized, so as to ensure preferably electrically
Stabilizability；Automatic welding operation can be achieved, reduce operating procedure and operating time, greatly improve work efficiency and life
Produce cost.Therefore, the utility model is simple in structure, is readily produced, is highly practical, convenient for being widely popularized on a large scale.

Specific embodiment
Further describe the utility model with reference to specific embodiment, but embodiment be only it is exemplary, it is not right
The scope of the utility model forms any restrictions.It will be understood by those skilled in the art that without departing from the utility model
Can the details and form of technical solutions of the utility model be modified or replaced under spirit and scope, but these are changed and replace
It changes and each falls in the scope of protection of the utility model.
A kind of novel switched terminal, including terminal shrapnel 1 and terminal bodies 2, the terminal shrapnel 1 and terminal bodies 2
Afterbody right-angled intersection is fixed, and the end of the terminal shrapnel 1 is welded with silver layer 3, and the silver layer is bulge-structure, the silver layer with
The terminal bodies are in same level.
Further, it is equipped with groove 4 with the another side of the terminal shrapnel of the bulge-structure face of the silver layer.
Further, the terminal shrapnel 1 and the afterbody of terminal bodies 2 are by being welded and fixed.
