Description
Technical field
The utility model relates to the joint element of integrated circuit contact terminal, specifically a kind of structure of novel integrated circuit contact terminal, this structure can make contact terminal when plugging and flatten the stage, the supporting part of contact terminal can be positioned on the same horizontal plane, and be unlikely to compressive deformation when assembling, help adhering to of tin ball.
Background technology
Contact combination between the pedestal of integrated circuit and motherboard now, broken away from the mode of welding again after in the past plugging, dispose the tin ball on the contact terminal in the integrated circuit pedestal earlier and be improved to, carry out soldering processing again, direct pedestal with integrated circuit is welded in the flow process on the motherboard.
The architecture advances that for this reason needs the integrated circuit contact terminal, a kind of contact terminal is arranged at present, and it offers a slotted hole, and is bent into a clip shape, slotted hole on this contact terminal plugs for the pin of integrated circuit, and its welding tin ball then is disposed at the open end of this contact terminal.
For this structure, this contact terminal and combining of tin ball are the open ends at contact terminal, be difficult to location and constraint, quite difficult, be easy to generate the vertical parallax between tin ball and adjacent tin ball again, and this tin ball is easy to generate the phenomenon that drops in implantation process, moreover, there is no a location structure or restraining structure between this contact terminal and pedestal, so this contact terminal equally also can produce the vertical parallax between contact terminal behind the terminal groove that inserts pedestal; Therefore, this kind structure can't make obtain between the pedestal of integrated circuit and motherboard accurately, excellent contact.
Another processing mode is as being the U.S. the 6th, 267, No. 615 the patent case is described, this contact terminal mainly includes base portion, alar part, elastic arm, clamping part and supporting part, and wherein this alar part is curved is located at substrate two side appropriate positions, and the tail end of alar part upwards extends into the gradually-reducing shape elastic arm, and be provided with clamping part in its apical margin, this clamping part has an asymmetric guiding face, and simultaneously supporting part is that lower end by base portion bends naturally and forms, and there is no any annexation with other position.
In the actual application process, because the supporting part of this contact terminal itself there is no any support, so when this contact terminal during in the set terminal pilot trench, this supporting part is very easily owing to collide, rub and cause the phenomenon of bending, and this supporting part can't be fixed on the same plane, thereby cause vertical parallax make contact terminal and tin ball can't in conjunction with or be difficult to reach well in conjunction with effect, badly influence the welding quality of integrated circuit contact terminal.
The guiding face of this contact terminal clamping part is asymmetric shape again, so make the displacement moving-wire of integrated circuit pin not smooth, therefore might cause the integrated circuit pin to produce curving in contact process, and then causes the phenomenon of loose contact to produce.Simultaneously, there is no a location structure between this contact terminal and pedestal, only depend on the frictional interference between contact terminal and pedestal terminal groove to locate, therefore this contact terminal is behind the terminal groove that inserts pedestal, can produce the difference of height between contact terminal, and make contact terminal quite difficult, and then cause producing between follow-up tin ball and adjacent tin ball difference of height with combining of tin ball; Moreover, because the quantity of contact terminal is quite a lot of in this pedestal, therefore under the situation of interference and extruding mutually, will make this pedestal produce distortion.
Therefore, this kind structure and can't make the pedestal of integrated circuit and motherboard between one accurately, excellent contact.
Summary of the invention

Another purpose of the present utility model is to make contact terminal when plugging and flatten the stage, and the supporting part of this contact terminal can be positioned on the same horizontal plane, and compressive deformation when being unlikely to assemble helps adhering to of tin ball.
Another purpose of the present utility model is the displacement moving-wire smoothness that makes the integrated circuit pin, contact terminal plug smoothness, accurate positioning, can not produce the pin distortion and the tin ball that causes thus between the problem of difference of height.
In order to achieve the above object, the utility model is achieved in that
A kind of contact terminal structure-improved of integrated circuit, it is disposed in a plurality of terminal grooves set on the base of integrated circuit pedestal; The supporting part that contact terminal includes base portion, Ji portion, elastic arm, clamping part and adheres to for the tin ball; Wherein, the curved aforesaid base plate two side appropriate positions of being located at of this alar part, and this alar part upwards extends spacing and is the gradually-reducing shape elastic arm, the apical margin of this elastic arm is provided with clamping part, and in the other end of this alar part each is extended with a support portion respectively, and the appropriate location of contiguous alar part respectively is respectively equipped with a stopper section in the substrate both sides; Can make contact terminal when plugging and flatten the stage by said structure, the supporting part of this contact terminal can be positioned on the same horizontal plane, and compressive deformation when being unlikely to assemble helps adhering to of tin ball.
This support portion is that the direction to supporting part is bending, and is connected in supporting part.
The relative both sides of the terminal groove of this base are respectively to offer a profile groove.
Above-mentioned profile groove is to be a downward gradually-reducing shape.
The set clamping part of the above-mentioned apical margin by elastic arm is a symmetrical structure.
Described clamping part has the guide surface that expands outwardly.
Described guide surface is a bending arc shape.
The utility model is connected alar part with supporting part by the support portion, make it to have the robust structure that can support, suitable collision, friction that can not be subjected to external force etc. influences, make the utility model in assembling process, guarantee enough intensity, the distortion of any parts can not take place, and can guarantee plugging smoothly of contact terminal.And the supporting part of contact terminal can be positioned on the same horizontal plane, and compressive deformation when being unlikely to assemble helps adhering to of tin ball.Can make the pedestal of integrated circuit accurate, well contact with motherboard.
And the utility model can make the displacement moving-wire smoothness of integrated circuit pin, contact terminal plug smoothness, accurate positioning can not produce the difference of height of contact terminal, can not produce the pin distortion and the tin ball that causes thus between the problem of difference of height.
