Abstract
The utility model relates to SMD technical field, especially a hardware terminal pin SMD, comprising a body and pins protruding therefrom, wherein the upper and lower ends of the tail portion of each pin are respectively provided with an inclined surface, the end surface of the tail portion of the pin and the two inclined surfaces form a trapezoid platform structure, the surface of the end surface of the tail portion of each pin is reduced, therefore the loss brought by oxidation of the end surface of the tail portion of each pin is avoided, the performance and service life of the product are improved, the production cost is effectively saved and the production efficiency is raised.
Description
Technical field:
The utility model relates to the SMD technical field, refers in particular to five metals terminal pins SMD.
Background technology:
SMD is the abbreviation of Surface Mounted Devices, means: surface mount device.After the SMD moulding, the five metals terminal pins that is exposed to the SMD body forms bending shape earlier by bending, and electroplates then, after plating is finished pin is separated with the strip cut-out.The cross section that cuts off the back pin is copper face, owing to the easy oxidation of this copper face causes scolding tin bad, can't reach the serviceability of product, has influenced the useful life of five metals terminal pins SMD.
The utility model content:
The purpose of this utility model is exactly to provide a kind of five metals terminal pins SMD that enhances product performance at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is: five metals terminal pins SMD, include body and stretch out this external pin, the two ends up and down of described pin tails respectively are provided with the inclined-plane, and the end face of pin tails encloses mutually with two inclined-planes and forms the bucking ladder structure.
The angle of inclination on described inclined-plane is 30～60 °.
The angle of inclination on described inclined-plane is 45 °.
Described bending pins becomes " Z " shape mechanism.
The ratio of the face area of described pin tails and pin area of section is less than 5%.
The utility model beneficial effect is: the five metals terminal pins SMD that the utility model provides, include body and stretch out this external pin, the two ends up and down of described pin tails respectively are provided with the inclined-plane, the end face of pin tails encloses mutually with two inclined-planes and forms the bucking ladder structure, reduce the pin tails face area, solved the loss that the end face oxidation because of pin tails brings, the performance and the useful life of having improved product, effectively saved production cost and improved production efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an end view of the present utility model.
Fig. 3 is the structural representation of the utility model pin.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1～3, the utility model five metals terminal pins SMD includes body 1 and the pin 2 that stretches out outside the body 1, the two ends up and down of described pin 2 afterbodys respectively are provided with inclined-plane 21, the angle of inclination on inclined-plane 21 is 30～60 °, in present embodiment, the angle of inclination on inclined-plane 21 is 45 °.The end face 22 of pin 2 afterbodys encloses mutually with two inclined-planes 21 and forms the bucking ladder structure, and end face 22 areas of pin 2 afterbodys and the ratio of pin 2 areas of section are less than 5%.Pin 2 is bent into " Z " shape mechanism.
After the SMD moulding, the utility model mainly is earlier by electroplating, and then through the cut-out one step forming that bends, so pin 2 cross sections that form are covered more than 95% by electrodeposited coating, and the ratio that is to say end face 22 areas of above-mentioned said pin 2 afterbodys and pin 2 areas of section is less than 5%.It had both solved because of the cross section oxidation brings loss, had improved the performance and the useful life of product simultaneously, and structure of the present utility model has effectively been saved production cost and improved production efficiency.
Certainly, the above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
