Description

Electric connector terminal

[technical field]

The utility model is about a kind of electric connector terminal, refers in particular to a kind of electric connector terminal that is used to electrically connect circuit board and planar grid encapsulation.

[background technology]

Along with the direction of calculator technology to miniaturization develops, electric connector also develops to more and more littler direction thereupon, and this electric connector has generally comprised insulating body and terminal.Because the insulating body size reduces, and makes that taking up room of terminal is more and more littler, guarantees the Elastic Contact performance that the terminal tool is preferable like this, to carry out the technical barrier that excellent electrical property connects just becomes the terminal manufacturing with corresponding planar grid encapsulation.In the face of the problems referred to above, a kind of existing technology is the arrangement mode of transforming between the insulating base of terminal and socket connector, such as No. the 444960th, the Taiwan patent announcement announced July 1 calendar year 2001 a kind of electric connector for socket of announcement.See Fig. 6, Fig. 7 for details, set in a row on the pedestal 8 of this electric connector for socket and be the terminal containing slot 80 that clathrate distributes, to accommodate corresponding terminal (not shown) in wherein, and every row's terminal containing slot 80 is the miter angle setting with the sidewall 82 of pedestal 8 respectively, by this scheme, can increase terminal in terminal containing slot 80 than large space, providing the terminal tool long elastic contact part, thereby obtain desirable electrical contact performance.Yet, because the restriction of existing terminal manufacturing technology, cause the terminal can't be simultaneously in a row or in the terminal containing slot 80 that accurately is assembled in pedestal 8 of embarking on journey.In addition, because the sidewall 82 of terminal containing slot 80 and pedestal 8 is the miter angle setting, thereby the core of mould also should be the miter angle setting, thereby increased the manufacture difficulty of core.

See also Fig. 8 and Fig. 9, be depicted as existing terminal 60 and a kind of terminal material belt 70 of making this terminal 60 that another kind is used for socket connector.Terminal material belt 70 is to be stamped to form on a slice metal material, the connecting portion 65 of plurality of terminals 60 that it comprises base band 66, be arranged side by side and splicing ear 60 and base band 66.Wherein each connecting portion 65 links to each other with two abutting ends 60, and corresponding each connecting portion 65 is provided with a location hole 67 on base band 66.Terminal 60 comprises a base portion 61, reaches the weld part 64 and elastic portion 63 that extend in the relative both side edges of base portion 61.Wherein base portion 61 is provided with protruding thorn 611 in relative two lateral margins of not establishing weld part 64 and elastic portion 63, in the pedestal (not shown) that terminal 60 is positioned socket connector.Elastic portion 63 is to extend sufficient length in the lateral margin bending of base portion 61, so that the preferable Elastic Contact performance of terminal 60 to be provided.Yet, because elastic portion 63 bending lengths of this terminal 60 are longer, and with the lengthwise of terminal material belt 70 to be arrangeding in parallel, make that the spacing of adjacent two terminals 60 on terminal material belt 70 is bigger, cause the manufacturing cost of terminal 60 to be difficult to reduce.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector terminal, machinery that its tool is preferable and electric property, and be installed in behind the electric connector and the pad of planar grid encapsulation between accurate positioning.

The purpose of this utility model is achieved in that this electric connector terminal comprises holding parts, and in extended cantilever of this holding parts opposite end and connecting portion.Wherein this cantilever comprise a base portion that links to each other with holding parts, from the big surface of base portion bearing of trend away from the oblique extension that extends to form of holding parts one end one, and from location division that the extending end bending of extension is extended.Extension is provided with the bigger first surface of surface area and bends in its bearing of trend and is provided with contact site.

Compared with prior art, the utlity model has following advantage: be subjected to improper external force effect when electric connector terminal and contact site is taken place when crooked, the location division can be connected to the madial wall of terminal containing slot, thereby restriction contact site offset displacement amount, thereby guarantee that contact site accurately is positioned the pad of planar grid encapsulation.When this electric connector terminal electrically contacts mutually with the planar grid encapsulation, the part first surface of contact site correspondence electrically connects mutually with the planar grid encapsulation, to guarantee to connect well, the base portion of cantilever and extension will produce strain jointly, so that the preferable Elastic Contact performance of electric connector terminal to be provided.
