A kind of SMT products connector

Technical field

The utility model is related to a kind of connector, more particularly, to a kind of SMT products connector.

Background technology

New energy vehicle air spring control connector, to stability, volume, energy consumption, cost proposes very high request.SMT connects Connecing device includes the plastic parts bending terminal different with two kinds, and plastic parts is provided with the two rows grafting inserted for bending terminal Mouthful, two kinds of different bending terminals are inserted in this two sockets interface respectively.For the welding of the bottom that ensures two kinds of bending terminals Pin is located at interval in same welding plane, good contact effect during realizing that connector is welded with pcb board, existing connector Bending terminal use flat board process technology, i.e., one flat plate is processed into structure as shown in Figure 1, wherein, (a) in Fig. 1, (b) two kinds of flat boards are represented respectively, then structure in Fig. 1 is subjected to twice bending, that is, form two kinds of bending terminals as shown in Figure 2. Such processing has following several defects：(1) due to the processing of flat board to be ensured, the thickness of bending part must be processed very Thin, which results in the current carrying capacity of bending terminal decrease；(2) during bending, dimensional accuracy is difficult to hold, and processing is stable Property it is poor, cause all bending terminals of connector welding foot be difficult to be located at same welding plane when；(3) two kinds of bending terminals Bending part is respectively positioned in same perpendicular so that the width of bending terminal is also excessively limited, and further reduces connector Current carrying capacity.

Utility model content

The purpose of this utility model is exactly the defect in order to overcome above-mentioned prior art presence and provides a kind of SMT products and use Connector.

The purpose of this utility model can be achieved through the following technical solutions：

A kind of SMT products connector, includes two row's bending terminals of plastic parts and access plastic parts, the two rows bending Terminal is respectively the long terminal of bending positioned at upper row and bending short end positioned at lower row, and the bending terminal includes access modeling The linkage section of glue part, lower surface forms the welding foot section of same weld interface, and the connection linkage section and welding foot section Bending section, the length that the linkage section of the long terminal of bending exposes plastic parts exceedes bending short end, and make it that bending is long Terminal is located in two different perpendiculars respectively with the bending section of bending short end.

It is preferred that, the bending section of the long terminal of described bending bending beat to the right, its side is in straight arm shape, and the bending is short The bending section of terminal bending beat to the left, its side is L-shaped.

It is furthermore preferred that the bottom of the plastic parts is additionally provided with limiting plate, stopper slot side by side, institute are additionally provided with limiting plate The welding foot section for stating bending terminal is caught in the stopper slot, and is met：The welding foot inserted in the stopper slot is so that " bending is short The mode of the long terminal of terminal-bending-bending short end " is spaced.

Even more preferably, the length of the bending section of described bending short end is met：Its lower surface just with it is described Limiting plate upper surface.

It is furthermore preferred that the deflection angle of the bending section of the long terminal of described bending and bending short end is met：With deflection angle It is one group, same group of the long terminal of bending and bending short end to spend the relative long terminal of adjacent bending in left and right and bending short end Linkage section be located at same perpendicular in.

It is preferred that, linkage section, welding foot section and the bending section punching press of described bending terminal are integrally formed.

Compared with prior art, the utility model has advantages below：

(1) middle part compared to two kinds of conventional bending terminals is respectively positioned in same perpendicular, the utility model By rational space arrangement, the middle part of the long terminal of bending with bending short end is changed to different positioned at two respectively Perpendicular in, the thickness of increase bending terminal that thus can be suitably improves its current carrying capacity.

(2) by the long terminal of bending and the relative bending deflection angle of the bending section of bending short end, it can make originally The bending terminal extended out from the linkage section positioned at same perpendicular that is located at be located at two different perpendiculars respectively, Prevent that bending terminal thickness can be increased while interference as far as possible.

(3) bending section of bending short end has also cooperatively formed a structural strengthening part with limiting plate, when positioned at welding When the welding foot of interface is by upward pressure, rigid counteracting can be carried out by the cooperation of bending section and limiting plate, to keep away Exempt from the interface that pressure on this is applied directly to bending terminal and plastic parts, and then interface is lost so that bending terminal and modeling The quality of connection of glue part is deteriorated.

(4) bending terminal of the present utility model is integrally formed using punching press, compared to conventional flat board bending technique, processing Stability and quality have obtained very big improvement.
