[embodiment]
Refer to shown in Fig. 1 to Fig. 2, the electric connector 100 of the better embodiment of the utility model one, be installed on printed circuit board (PCB) (not shown) for being electrically connected wafer module (not shown), it includes insulating body 1 and some terminals 2.More show the insulating body 1 of electric connector 100 of the present utility model and the minutia of some terminals 2 in order to clearer, Figure of description only show the structure of the subregion of this electric connector 100.
Insulating body 1 has end face 101 and the bottom surface 102 towards printed circuit board (PCB) (not shown).This insulating body 1 is provided with the some terminal grooves 11 running through end face 101 and bottom surface 102.Each terminal groove 11 also comprises the holding slot 110 that is positioned at this terminal groove 11 side, for holding terminals 2.Shown in Fig. 3, described terminal groove 11 is matrix arrangement along longitudinally X and horizontal Y, is provided with blank space 15 between adjacent row's terminal groove 11.Described insulating body 10 is also provided with some boss 12, and described boss 12 protrudes out from described end face 101, between described some terminal grooves 11.Described boss 12 comprises Part I 120 and Part II 122, and two parts are arranged in splayed substantially, and concrete structure and the function of this boss 12 will be introduced later in detail.
Shown in figure 1, described terminal 2 comprises base portion 21, the elastic arm 22 that upwards extends from base portion 21, continue the weld part 24 to downward-extension from base portion 21 to the holding parts 23 of downward-extension and from holding parts 23.Described base portion 21 comprises the linking arm 25 be connected with described holding parts 23 further, and the bent over arms 26 be connected with described elastic arm 22, and described linking arm 25 is connected to each other at a certain angle with bent over arms 26.The top of linking arm 25 is for connecting material strip.Described terminal 2 from top to bottom group enters described insulating body 1, described holding parts 23 and connecting portion 25 hold with in holding slot 110, described elastic arm 22 extends upward the end face 101 of insulating body 1, and described weld part 24 is fixed with a tin ball (not shown) jointly with insulating body 1.The end of elastic arm 22 is provided with contact site 220, in electrical contact with wafer module.
Shown in composition graphs 3 and 4, described elastic arm 22 is inclined upwardly extension above the end face 101 of insulating body 1, run through from end face, the bearing of trend of elastic arm 22 relative to aforementioned longitudinally X and horizontal Y all at an angle, defining this bearing of trend is first direction A, and define another direction perpendicular to above-mentioned first direction A is second direction B simultaneously.Described boss 12 is positioned at the side of this elastic arm 221 along this second direction.Through this boss 12 when described elastic arm 22 extends, corresponding contact portion 220 is positioned at the front of this boss 12 along described first direction.Described elastic arm 22 is also provided with the butting section 221 adjoining described boss 12.Shown in composition graphs 4, observe from side, the part-structure of this butting section 221 is lower than this boss 12, and when described elastic arm 22 is subject to external force left and right deflection, this butting section 221 side direction can abut to this boss 12, avoids elastic arm more than 22 to spend deflection and causes deformation failure.
The above-mentioned Part I 120 of described boss 12, near above-mentioned butting section 221, is roughly arranged along above-mentioned second direction.Above-mentioned Part II 122 from Part I 120 transversely Y extend away from direction, above-mentioned butting section 221, and extend to adjacent blank space 15.So that for the elastic arm 22 of adjacent another terminal 2 provides spacing left and right.Shown in composition graphs 3, be the boss of 13 for label, it is crooked counterclockwise that the Part I 130 of this boss 13 can limit the terminal 26 being positioned at one side, and can to limit the terminal 27 being positioned at opposite side crooked clockwise for the Part II 132 of this boss 13 simultaneously.That is, same boss 12 can provide position-limiting action to adjacent two terminals 2.Change kind of a mode to describe, terminal 26 is subject to the restriction of adjacent two boss 13,14, can avoid excess divergence in the both direction of left and right.Electric connector 100 boss 12 of the present utility model is set to by Part II 122 position-limiting action that terminal 2 provides other direction, can protect terminal 2 preferably.
On the other hand, the boss 12 of the utility model electric connector 100 can also terminal 2 amplitude of deformation that causes when pounding for 5 times of the wedge angle of limit wafer module, shown in figure 3, still illustrate with boss 13,14, the Part II 142 of boss 14 shortens the horizontal Y space between boss 14 and adjacent lands 13.Fig. 5 is schematic diagram, pounds between boss 13,14 under the wedge angle of display wafer module, is omitted for the ease of observing terminal 26.Shown in composition graphs 5, because horizontal Y space is by limit, namely the distance of Part II 142 to boss 13 Part I 130 reduces, the height that the wedge angle of wafer module is pounded for 5 times is reduced, so corresponding by under the amplitude that is pressed down of the terminal 26 pounded be reduced, the inefficacy caused because excessively pressing down can be avoided.
In sum, these are only preferred embodiment of the present utility model, scope of the present utility model should do not limited with this, namely every simple equivalence change done according to the utility model claims and description with modify, all should still belong in scope that the utility model patent contains.
