The utility model also disclosure an electric connector using the terminal, the base part and the bended part of the electric connector terminal are formed approximately as a right angle, so that the electric connector terminal can be better positioned in the insulating body, the space of a terminal holding groove can be reduced, and the electric connector terminals can be arranged more closely.
Description
[technical field]
The utility model is about a kind of electric connector terminal and uses the electric connector of this terminal, especially refer to a kind of can more closely arrange and accurately the location electric connector terminal and use the electric connector of this terminal.
[background technology]
At present, the IC chip that has occurred a kind of LGA (planar lattice array) type on the market, corresponding with it a kind of electric connector that connects this chip and circuit board appearred, an end that is connected with chip on the common this electric connector protrudes out insulating body, to contact with the conductive junction point elastic compression of chip.In order to increase the spacing between terminals of adjacent and to obtain preferable electric property, terminal bends portion is roughly extended along the diagonal of terminal containing slot.Be this structure as the utility model patent that the patent No. is 02254746.0, name is called " electric connector terminal ".This electric connector terminal comprises base portion, weld part and elastic portion.Wherein this base portion below is provided with holding parts; This weld part goes out from the terminal vertical extent of holding parts, to be soldered on the circuit board; This elastic portion is extended from the base portion side, and comprise kink and on this kink terminal extended bend, this bend is provided with the contact site of arcuation in its free terminal, to contact with the conductive junction point elastic compression of chip.This kink and base portion are provided with (being generally 135 degree) in obtuse angle.This base portion is provided with some hangnails in the two sides of contiguous holding parts, with by with the insulating body interference engagement electric connector terminal being immobilizated in the terminal containing slot of insulating body.But should there be following defective by existing electric connector terminal: because kink and base portion are provided with in obtuse angle, make the terminal containing slot that holds this terminal must make greatlyyer, comparatively be closely aligned thereby can't make between terminals of adjacent, can not adapt to the more needs of high density electrical connector; And the terminal that kink and base portion are provided with in obtuse angle is difficult for accurately location, and can cause the insulator structure complexity.
So the electric connector that is necessary to design a kind of novel electric connector terminal and use this terminal is to overcome above-mentioned defective.
[summary of the invention]
The electric connector that the purpose of this utility model is to provide a kind of electric connector terminal that can more closely arrange and accurately locate and uses this terminal.
Weld part and elastic portion that the utility model electric connector terminal comprises base portion, extends in an end of base portion, this elastic portion is provided with in the extended kink in the side of base portion and in the terminal further extended bend of this kink, this bend and kink are at the certain angle of lateral tilt, and roughly at right angles setting between this base portion and kink.
The utility model electric connector comprises the insulating body that is provided with terminal containing slot and is contained in terminal in this terminal containing slot, weld part and elastic portion that this terminal comprises base portion, extends in an end of base portion, this elastic portion is provided with in the extended kink in the side of base portion and in the terminal further extended bend of this kink, this bend and kink are at the certain angle of lateral tilt, and roughly at right angles setting between this base portion and kink.
Compared with prior art, the base portion of the utility model electric connector terminal and kink roughly at right angles are provided with, thereby electric connector terminal can be positioned in the insulating body preferably, and can dwindle the space of terminal containing slot, thereby it is more tight that electric connector terminal is arranged.

[embodiment]
To shown in Figure 5, the utility model electric connector terminal 1 comprises base portion 10, weld part 12 and elastic portion 14 as Fig. 1.This weld part 12 is extended by the lower end of base portion 10, to be soldered on the circuit board (not drawing among the figure); This elastic portion 14 is extended from base portion 10 sides, and comprise the kink 16 of tool certain radian and terminal extended bend 18 on this kink 16, this bend 18 is provided with the contact site 20 of arcuation in its free terminal, to contact with conductive junction point (not drawing among the figure) elastic compression of chip.This bend 18 and kink 16 are at the certain angle of lateral tilt, and this base portion 10 and 16 roughly at right angles settings of kink.This base portion 10 is provided with overhead kick 22 in a side of contiguous weld part 12, on the projection 32 that is fastened in insulating body 3, electric connector terminal 1 fixing is contained in the terminal containing slot 34 of insulating body 3, to form electric connector.This weld part 12 can directly weld with circuit board mutually, also can with terminal containing slot incompatible clamping one scolder 4 (as the tin ball) that matches, be welded to connect by this scolder and circuit board.
Above-mentioned electric connector terminal is to form like this: earlier a sheet metal stamping-out is become terminal blank 1 ' as shown in Figure 2, this blank 1 ' roughly form base portion 10, by the extended weld part 12 ' of base portion 10 ' lower end, by the extended kink 16 ' in base portion 10 ' side and with the bend 18 ' of kink 16 ' at the lateral tilt certain angle.And then with the base portion 10 ' and about 90 degree of kink 16 ' bending of this terminal blank 1 ', and kink 16 ' bent to be certain arc, bend 18 ' and kink 16 ' are bent into roughly rectangular, and bend 18 ' further bends to shape as shown in Figure 1.
Compared with prior art, the base portion of the utility model electric connector terminal and kink roughly at right angles are provided with, thereby electric connector terminal can be positioned in the insulating body preferably, and can dwindle the space of terminal containing slot, thereby it is more tight that electric connector terminal is arranged.And the kink of the utility model electric connector terminal has certain radian, thereby makes this terminal have bigger elasticity, helps being connected better with chip.Moreover the utility model electric connector terminal is established overhead kick at base portion and is held mutually with projection on the insulating body and fix, and compared to the interference engagement of prior art, can more firmly electric connector terminal be fixed in the insulating body.In addition, this weld part and base portion are approximately perpendicular to circuit board roughly at grade when welding mutually with circuit board, thereby can be directly welded on the circuit board, can terminal be welded on the circuit board with terminal containing slot incompatible clamping one scolder that matches again.
