Summary of the invention
The utility model provides a kind of USB interface electric connector terminal structure of being convenient to the one-to-many welding, its objective is the difficulty that will reduce the welding of one-to-many terminal, improves one-to-many terminal welding reliability, to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of USB interface electric connector terminal structure of being convenient to the one-to-many welding, this terminal is on length, comprise that the front portion is provided with the Elastic Contact section, the middle part is provided with the positioning and fixing section, the rear portion is provided with welding wiring section, and its innovation is: the afterbody of welding wiring section is designed to " Y " shape branched structure.
Related content in the technique scheme is explained as follows:
1. this programme is at USB 2.0 terminals and USB 3.0 terminal combination together the time, the improvement that the defective that USB 3.0 terminals exist is carried out.Described " Elastic Contact section " is meant the front portion that is positioned at USB 3.0 terminal length directions, is used for the part that elasticity is electrically connected; " positioning and fixing section " is meant the middle part that is positioned at USB 3.0 terminal length directions, is used to locate the part with fixed terminal; " welding wiring section " is meant the rear portion that is positioned at USB 3.0 terminal length directions, is used for the part of soldered wires.
2. in the such scheme, can in each branch of " Y " shape branched structure, deep-slotted chip breaker be set along its length for the ease of welding.
The utility model principle and effect are: in order to solve the problem of USB3.0 earth terminal one-to-many welding difficulty, the welding wiring segment trailer of terminal is designed to " Y " shape branched structure.Share the weld task of one-to-many by " Y " shape branched structure, can reduce the welding difficulty like this, improve welding reliability, simple in structure simultaneously and be easy to processing.
