Description
Technical field
The utility model relates to the terminal welding structures of technical field of electric connectors, especially electric connector.
Background technique
Electric connector is a kind of component for transmitting electronic signal, transmits signal by most terminals in connector.Currently,
Electric connector upper plate assembling in use, some electric connectors by SMT technique connect circuit board, the one of the terminal of the electric connector
End is equipped with weld part, and the weld part of terminal is welded on the preset contact of circuit board by tin cream, specifically: the weld part of terminal
It is mounted on the preset contact of circuit board and welds, tin cream is the tin that climbs up from two avris of weld part.This mode there are it is following not
Foot:
1, it when the weld part of terminal can not be bonded completely with circuit board, be easy to cause and eats not full tin, missing solder, rosin joint etc.
It is bad, lead to not normally transmit signal.
2, the number of terminals of electric connector is more and closeer, when SMT technique, the weld part and circuit board of terminal often occurs
The case where preset contact contraposition deviation, and the tin cream on the preset contact of circuit board is centrally arranged with respect to contact, is also occurred as soon as
The weld part of terminal cannot be contacted well with tin cream, caused the weld part of terminal to be unable to reach two sides and climbed tin, be easy to cause and eat tin
Not full, missing solder, rosin joint etc. are bad；At this moment, if increasing the tin cream amount on the preset contact of circuit board, it will appear excessive tin phase
The case where neighbour is shorted, causes bad products.
3, tin cream is only the tin that climbs up from two avris of weld part, and the welding surface of terminal weld part is small, if terminal welds
Portion increases attachment area, then is unfavorable for welding exhaust and the weld job of tin is climbed in tin cream flowing.

The through-hole of the upper side of weld part.
Above scheme is further: the upper side of the attachment face of the weld part and weld part be arranged in parallel up and down, and
Height distance between attachment face and the upper side of weld part meets the upper side that tin cream via through holes climb to weld part.
Above scheme is further: the through-hole has one or more, and the shape of through-hole is ellipse, circle or polygon
Shape.
Above scheme is further: the weld part is flat and the axis of opposing terminal ontology does two sides and widens.
The weld part of the utility model has the attachment face of adaptation SMT technique, and perforation attachment face is equipped on weld part
With the through-hole of the upper side of weld part, thus have the following beneficial effects:
1, when welding, tin cream can climb tin simultaneously from the two sides of intermediate throughholes and weld part, and climbing tin can be more, opposite to weld
Understand, avoids eating not full tin, missing solder, rosin joint etc. bad.
2, what the internal perisporium of through-hole increased weld part eats tin face, facilitates promotion signal transporting and firm welding.
3, using the through-hole on weld part, it can help to welding exhaust and the weld job of tin climbed in tin cream flowing, reduction is suppressed
Bubble is welded caused by gas, promotes welding quality.
4, facilitate to solve the problems, such as the contraposition deviation of SMT technique, improve processing procedure, promote validity, the yield rate of SMT technique
And operability.
Detailed description of the invention:
Attached drawing 1 is the utility model one example structure schematic diagram；
Attached drawing 2 is Fig. 1 embodiment overlooking structure diagram；
