Abstract
The utility model discloses a solve the poor problem of product soldering tin foot rosin joint and last tin infiltration nature that appears in the contact terminal welding process among the current computer input/output connector, it is insecure to avoid the solder joint welding, the defect rate is high, a better solder foot structure of contact terminal among the computer input/output connector of soldering tin nature is provided, any one side of solder foot is the cockscomb structure, the tin consumption through the multiplicable solder foot of cockscomb structure solder foot structure improves the soldering tin performance of product, it is more firm to make the solder joint. The utility model has the advantages that: the tin consumption of the welding leg is increased, so that the tin soldering performance of the product is improved, the defect rate of welding points is low, the vibration resistance is high, and the safety performance of the product is high.
Description
Technical field
The utility model relates to the leg structure that is used for surface installation technique, relates to a kind of leg structure of computer input and output connector contact terminal particularly.
Background technology
Surface installation technique (SMT) is the most frequently used a kind of technology and a technology in the present electronics assembling industry.Be characterized in: packaging density height, electronic product volume are little, in light weight, and the volume and weight of surface mount elements has only about 1/10 of traditional inserting element, generally adopts after the SMT electronic product volume-diminished 40% ~ 60%, weight saving 60% ~ 80%.Contact terminal also adopts surface installation technique in the existing computer input and output connector, in welding procedure, adopt the smooth leg structure of outer surface, the problem that product scolding tin pin rosin joint and last tin wettability difference often occur, the welding point defect rate is higher, thereby influence the antivibration ability, make product be prone to quality and safety problem.
Summary of the invention
The utility model purpose is for solving the product scolding tin pin rosin joint that occurs in the contact terminal welding process in the existing computer input and output connector and the problem of last tin wettability difference, avoid the solder joint not prison welding solid, the ratio of defects height provides solderability better a kind of leg structure.
The utility model is achieved through the following technical solutions goal of the invention, the leg structure of contact terminal in a kind of computer input and output connector, arbitrary of leg is zigzag, can increase the tin amount of eating of leg by zigzag leg structure, improve the scolding tin performance of product, make solder joint more firm.
The beneficial effects of the utility model are: increased the tin amount of eating of leg, thereby improved the solderability of product, the welding point defect rate is low, antivibration ability height, product safety performance height.
Description of drawings
Fig. 1, existing general leg structure chart.
Fig. 2, the leg structure chart of band saw dentation leg face.
Fig. 3, computer input and output connector structure chart.
Among the figure, 1 leg, 2 zigzag solders side, 3 insulating bases, 4 contact terminals.
Embodiment
A kind of computer input and output connector of band saw dentation leg structure comprises insulating base 3 and contact terminal 4, and zigzag leg 1 is positioned at the terminal of contact terminal 4, and contact terminal 4 is fixed on the insulating base 3.The computer input and output connector contact terminal 4 of this kind band saw dentation leg structure is welded to connect firmly behind surface installation technique scolding tin, and the scolding tin performance is good, transmission signals reliability height.
