Description
Technical field
The utility model is about a kind of socket connector terminal, particularly about a kind of conducting terminal that is used for zero-force connector for socket.
Background technology
Chinese patent discloses a kind of socket connector terminal No. 01226353.As shown in Figure 1, this socket connector terminal 1 includes a matrix 10 and a pair of arm 20.Head 12 in the terminal containing slot that this matrix 10 comprises the body 11 that abuts against the accepting groove inwall in the terminal containing slot that is housed in connector, be retained on socket connector, and can be welded on weld part 13 on the printed circuit board (PCB) (not shown).Arm 20 extends from the relative side of body 11, and it includes the forearm 21 of relative extension setting and the metacarpus 23 of stretching and expanding outwardly to body 11 directions edge from contact site 22.Be formed with one first space 210 between this two forearm 21, and be formed with a slit 220 in first space 210 and between two contact sites 22.One second space 230 is formed between the above-mentioned metacarpus 23 and at slit 220 places and communicates with first space 210, and above-mentioned slit 220 all is wider than in first space 210 and second space 230.CPU (chip) inserting foot be able to be interposed between the above-mentioned contact site 22, with being electrically connected of realization and terminal 1.
This socket connector terminal 1 is located at the contact site of clamping chip inserted pin between its metacarpus 23 and the forearm 21, in order to have strengthened the chucking power to the chip inserted pin.The metacarpus 23 of terminal 1 is the splayed structure simultaneously, and with the transition of termination contact portion 22 smooth connection partly, can make 22 the smooth surface slippage of CPU inserting foot, avoid scratching because of 1 of CPU inserting foot and terminal contact the excessive contact-making surface that causes of resistance along metacarpus 23 to contact site.
Yet the elastic arm of this socket connector terminal is from base portion two lateral bucklings, for assurance elastic arm especially forethiga wants long enough, thereby causes the bigger waste of material.Chinese patent 01279922.x and the 01279859.2 zero insertion socket connector terminal that discloses though avoided right its base portion of the problem of waste of material narrower, are difficult to guarantee the stable of whole terminal structure in addition.
In view of the foregoing, be necessary the terminal of existing socket connector is done further to improve, can guarantee that when reducing cost terminal structure is stable.
The utility model content
The purpose of this utility model just is to provide a kind of conducting terminal of socket connector, and this conducting terminal Stability Analysis of Structures can provide enough Elastic Contact power, and the spacing of terminal base portion on strip is less, saves material, and production cost is low.
For achieving the above object, the utility model provides following technical proposals: a kind of conducting terminal of socket connector, have a base portion, a weld part from this base portion one end bending extension, and from least one elastic portion of this weld part with respect to the other end extension of base portion.
Elastic portion has a junction, this connecting portion extends two elastic arms certainly, reaches the metacarpus that extends from each elastic arm.Base portion is tabular, and its both sides are provided with some hangnails, in the respective terminal accepting groove that conducting terminal is immobilizated in socket connector.Weld part also is a tabular, is used to be soldered to circuit board.Connecting portion is to be parallel to base portion from weld part one end to extend each elastic arm and comprise the forearm that extends from connecting portion, and the postbrachium that slopes inwardly and extend from forearm.Metacarpus comprises the guidance part near base portion, and the contact site of self-aiming portion extension.Be the guiding space between guidance part and the base portion.In another embodiment, connecting portion is to be tilted to base portion from weld part one end to extend.Metacarpus comprises the contact site near base portion, reaches the guidance part that extends from contact site; Be the guiding space between two guidance parts.
Compare with the conducting terminal of existing socket connector, the elastic portion of conducting terminal of the present utility model is to extend from weld part, but not from base portion two lateral bucklings; Thereby the spacing of terminal base portion on strip is less, has the saving strip, the advantage that production cost is low.Have the quite long elasticity arm of force on the other hand again, can provide enough Elastic Contact card contact site of trying hard to keep closely to contact with contact pin.
