When chip module 7 presses down, the contact site 924 of conducting terminal 92 contacts with chip module conducting strip 71, along with further pressing down of chip module 7 is mobile, the elastic arm 922 meeting strains of conducting terminal 92, make contact site 924 produce a bigger displacement in the horizontal direction with on the vertical direction with respect to holding parts 920, bigger displacement makes the conducting strip 71 of conducting terminal contact site 924 disengaging chip modules 7 easily on the horizontal direction, has influence on the contact quality of whole electric connector.
Therefore, the electric connector that is necessary to design a kind of new electric connector terminal and uses this electric connector terminal is to overcome the shortcoming that above-mentioned electric connector exists.
[utility model content]
The technical problem that the utility model solved provides a kind of electric connector of electrically connecting the electric connector terminal of quality and using this electric connector terminal of can effectively guaranteeing.
For achieving the above object, the utility model adopts following technical scheme: a kind of electric connector terminal and use the electric connector of this electric connector terminal, this electric connector comprises insulating body and is contained in the interior electric connector terminal of insulating body, insulating body comprises some accepting grooves that extend up and down, electric connector terminal comprises the holding parts that is housed in the accepting groove, from a downward extended weld part and the elastic portion that is used to electrically connect printed circuit board (PCB) of holding parts one end, the arm that connects with holding parts that elastic portion comprises that the elastic arm that extends upward from the holding parts other end and own elasticity arm one end extend to form towards the holding parts direction, the end of elastic portion is provided with the contact site and the chip module that extend insulating body and electrically connects.
Compared to prior art, the utility model electric connector has following advantage: when the contact site of mode of pressing below the chip module and electric connector terminal electrically connects, the arm of electric connector terminal can slide along holding parts, make contact site produce less displacement in the horizontal direction, effectively guaranteed the contact site of electric connector terminal and the electric connection between the chip module.

Fig. 2 is the cut-away view of the utility model electric connector, and wherein electric connector terminal is not connected with chip module and printed circuit board (PCB).
Fig. 3 is the cut-away view of the electric connector relevant with the utility model, and wherein electric connector terminal is connected with chip module and printed circuit board (PCB).
[embodiment]
Below in conjunction with embodiment the utility model is described.See also shown in Fig. 1,2, a kind of electric connector 100 is used to electrically connect chip module 4 to printed circuit board (PCB) 5, and it comprises insulating body 2 and is housed in electric connector terminal 1 in the insulating body 2.Wherein insulating body 2 comprises that the accepting groove 21 that some above-below directions extend is used to accommodate electric connector terminal 1.
Please consult shown in Figure 1ly simultaneously, electric connector terminal 1 comprises vertically the holding parts 11 that extends, from the extended downwards flat weld part 12 of holding parts 11 1 ends and the head 13 and the elastic portion 14 that extend upward from holding parts 11 other ends.Holding parts 11 dual-sides are provided with the madial wall interference engagement of the accepting groove 21 of some hangnails 110 and insulating body 2, make electric connector terminal 1 firm being positioned in the insulating body 2.In the present embodiment, head 13 be the long strip-board shape structure and with holding parts 11 coplanes, it can make electric connector terminal 1 more firm being positioned in the insulating body 2, head 13 also can be designed to other shapes to reach same effect.
Please consult shown in Figure 2 simultaneously, conducting strip 41 corresponding on the contact site 1411 of electric connector terminal 1 and the chip module 4 electrically connects, and the weld part 12 of electric connector terminal 1 is by corresponding bonding pad (sign) electric connection on welding tin ball 3 and the printed circuit board (PCB) 5.When chip module 4 contacted with the contact site 1411 of electric connector terminal 1 in the mode that presses down, the elastic arm 141 of electric connector terminal 1 was subjected to the downforce effect of chip module 4 towards holding parts 11 direction strains.Simultaneously, arm 143 moves until chip module 4 and electric connector 100 along holding parts 11 and reaches final contact condition, and the contact site 1411 of electric connector terminal 1 realizes that with the conducting strip of chip module 4 41 excellent electrical property is connected.
