Chinese patent application discloses No. 101316023 and has also disclosed a kind of electric connector terminal relevant with the utility model.This electric connector terminal comprises base portion, from the base portion top upwards the contact arm that extends of bending, extend the hook portion that is used for the fixing scolder from the base portion bottom downwards and extend the auxiliary connecting portion that is used for the splicing ear strip from base portion one side.But the contact arm of this electric connector terminal and hook portion also need roughly be positioned at same straight line up and down, can't electrically connect there are skew in chip module and printed circuit board (PCB) at vertical direction corresponding conducting strip.
Given this, be necessary to provide a kind of improved electric connector terminal in fact, to overcome the defective of described electric connector terminal.
[utility model content]
The technical problem that the utility model solved provides the electric connector terminal that has certain deviation between a kind of conducting strip that electrically connects chip module and printed circuit board (PCB).
For solveing the technical problem, the utility model relates to a kind of electric connector terminal, comprise base portion, by the upwardly extending contact arm of base portion and be located at the afterbody that the base portion lower end is used to connect scolder, wherein, described contact arm comprise all angled with plane, base portion place and an other perpendicular vertical with plane, base portion place and be inclined upwardly extend first contact arm that is provided with and by the first contact arm top oppositely towards base portion and be inclined upwardly and extend second contact arm of setting, the second contact arm top is provided with contact site, and there are certain deviation in described contact site and afterbody at vertical direction.
Compared with prior art, the utlity model has following advantage: there are certain deviation in the contact site of electric connector terminal and afterbody in the vertical direction, can satisfy the demand that vertical direction has the conducting strip of the chip module of certain deviation and printed circuit board (PCB) that is connected.

Fig. 4 is that electric connector terminal shown in Figure 3 is connected with terminal material belt and the electric connector terminal stereogram after by bending.
Fig. 5 is similar to Fig. 3, but takes from an other angle.
[embodiment]
See also Fig. 1 to shown in Figure 2, the utility model is a kind of electric connection chip module (not shown) and the electric connector terminal 1 of printed circuit board (PCB) (not shown), and this electric connector terminal 1 comprises base portion 10, by base portion 10 upwardly extending contact arms 11 and be located at the afterbody 12 that base portion 10 lower ends are used for the clamping scolder.
The base portion 10 of electric connector terminal 1 roughly is plate-like structure, and the deviation portion 101 that is provided with upwards and is forward extended on its top, and this deviation portion 101 further extension is provided with roughly c-shaped contact arm 11.This contact arm 11 comprises by be inclined upwardly first contact arm 111 that extend to be provided with and by first contact arm, 111 tops oppositely inwardly and be inclined upwardly and extend second contact arm 112 that is provided with of deviation portion 101 tops.Wherein, first contact arm 111 of this contact arm 11 and plane, base portion 10 place and the perpendicular all angled mode vertical and obliquely extend upward setting with plane, base portion 10 place.In addition, first contact arm 111 and second contact arm 112 are asymmetric design.First contact arm, 111 development lengths are greater than the development length of second contact arm 112.Second contact arm, 112 tops are provided with the contact site that is convex structure 113 that connects with chip module (not shown).So, also there are certain deviation in the contact site 113 of electric connector terminal 1 and afterbody 12 in the vertical directions, can satisfy the corresponding conducting strip that connects chip module and printed circuit board (PCB) by this has the demand of certain deviation at vertical direction, can provide client's electronic circuit bigger design flexibility.
Electric connector terminal 1 base portion 10 both sides roughly in middle and be provided with some holding parts 13 on the top, are used for electric connector terminal 1 is fixed in insulating body (not shown).Electric connector terminal 1 base portion 10 bottoms are provided with afterbody 12, and this afterbody 12 comprises two parts that parallel interval is provided with, and is used for fixing tin ball (not shown).Base portion 10 1 sides are provided with the protuberance 14 parallel with holding parts 13 in holding parts 13 upper sides to protruding out.These protuberance 14 tops are splicing ear strip 2 directly, electric connector terminal 1 need not be provided with the supplementary structure that is extended by base portion 10 1 lateral bucklings in addition and remove the splicing ear strip thus, simplified the structure of electric connector terminal 1 thus, saved taking up room of electric connector terminal 1, help realizing the high-density arrangement of electric connector terminal 1, and reduced the height of electric connector terminal 1, can satisfy the trend of electric connector miniaturization development.
