It is used as preferred technical scheme：Described pressure tongue is wide in width≤wallboard of wallboard horizontal center line vertical direction
Degree.
It is used as preferred technical scheme：Width of the described pressure tongue in wallboard horizontal center line vertical direction>Wallboard width.
It is used as preferred technical scheme：Described projection is protruded in groove.
It is used as preferred technical scheme：Described projection is symmetricly set on wallboard, quantity at least two.
It is used as preferred technical scheme：Described projection is flexible.
The beneficial effects of the utility model are：A kind of SMD metal terminal of solidus, SMD design will using charging tray
Solidus metal terminal body braid, saves space, and small volume, machine welding precision is high, and reliability is high, each chip module it
Between can be interference-free normal work；It is provided with the groove for being formed in the middle of wallboard, wallboard and being easy to perforate line so that wire is arranged
It is attractive in appearance, do not result in wire and the bad phenomenon such as knot, get lines crossed；Projection serves the effect for blocking wire, prevents wire in welding
Shift；Pressure tongue serves wire in welding, adds the effect that wire solder joint is puted forth effort, whole with circuit pads formation one
Body impetus so that solder joint is more firm.
Brief description of the drawings
Fig. 1 is the utility model graphics；

Embodiment
The utility model is further described below in conjunction with the accompanying drawings；
In the accompanying drawings：A kind of SMD metal terminal of solidus, including the terminal body being connected with circuit pads 102；
Described terminal body includes wallboard 1；The groove 2 for being easy to perforate line 103 is formed in the middle of described wallboard 1 so that the row of wire 103
Cloth is attractive in appearance, does not result in wire 103 and knots, the bad phenomenon such as get lines crossed；The described end of wallboard 1 is provided with pressure tongue 3, and side is set
There is the projection 4 for blocking wire；Press one overall impetus of tongue 3 and the formation of circuit pads 102 so that solder joint 104 is more
Firmly；Projection 4 serves the effect for blocking wire 103, prevents wire 103 in welding shift.
In Fig. 1, Fig. 2：The plane 101 fitted with circuit pads 102 is additionally provided with described wallboard 1；Plane 101
So that during chip mounter paster, positioning is easily bonded between wallboard 1 and circuit pads 102, it is easy to machine automatic welding, welding essence
Degree is high, and speed is fast.
In Fig. 1：Described wallboard 1 is quadrilateral structure.
In Fig. 1：Described wallboard 1 is " Ω " shape structure.
In Fig. 1, Fig. 2：Described pressure tongue 3 is protruded outside wallboard 1, is serpentine structure.
In figure 3：Described pressure tongue wallboard horizontal center line vertical direction width≤wallboard width, it is specious,
Save material.
In figure 3：Width of the described pressure tongue in wallboard horizontal center line vertical direction>Wallboard width, adds pressure tongue 3
Intensity.
In figure 3：Described projection 4 is protruded in groove 2, is easy to block wire 103；Described projection 4 is symmetrical arranged
