[utility model content]
The purpose of this utility model is to provide a kind of electric connector, and its terminal can be avoided being scratched.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of electric connector, for accommodating wafer module, it comprises and is provided with insulating body and some terminals, described insulating body is provided with end face, bottom surface and some terminal grooves running through end face and bottom surface, described terminal comprises base portion, from the elastic arm that base portion upwards extends, the weld part to downward-extension is continued to the holding parts of downward-extension and from holding parts from base portion, described elastic arm end is provided with arc-shaped contact site, the definition of this convex structure has a center of circle, vertically, the end minimum point of this contact site is concordant with this center of circle or be positioned at the below in the center of circle.
Described base portion comprises the linking arm be connected with described holding parts and the bent over arms be connected with described elastic arm further, and described linking arm and bent over arms are connected to each other at a certain angle.
The end minimum point of this contact site and the line in this center of circle and start from this center of circle and angle between the straight line vertically extended is equal to or less than 90 degree downwards.
The end of this contact site is become arc section by inflection, makes this contact site be bird head.
The end of this contact site is become non-arc section by inflection.
Insulating body is provided with the some boss upwards protruded out of end face, described elastic arm is also provided with the butting section adjoining described boss, and when described elastic arm is subject to external force left and right deflection, this butting section side direction can abut to this boss, avoid elastic arm, many degree deflections cause deformation failure.
Compared to prior art, the utility model electric connector has following beneficial effect: the terminal of the utility model electric connector can reduce the risk be scratched.
[accompanying drawing explanation]
Fig. 1 is the stereogram of the utility model electric connector.
Fig. 2 is the end view of the utility model electric connector.
[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 (non-label) that is positioned at this terminal groove 11 side, for holding terminals 2.Described insulating body 10 is also provided with some boss 12, and described boss 12 upwards protrudes out from described end face 101, between described some terminal grooves 11.
The elastic arm 22 that described terminal 2 comprises base portion 21, upwards extend 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 and the bent over arms 26 be connected with described elastic arm 22 further, and described linking arm 25 is connected to each other at a certain angle with bent over arms 26.The top of described 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 above-mentioned holding slot, 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.Described elastic arm 22 is also provided with the butting section 221 adjoining described boss 12.The height 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.
Shown in composition graphs 2, elastic arm 22 is provided with contact site 220 on its top, and this contact site 220 is arc-shaped, and the center of circle defining this convex structure is P.Vertically, end 223 minimum point 225 of contact site 220 is concordant with center of circle P or be positioned at the below of center of circle P, for the ease of observation and comparison, has marked horizontal line L 1 in fig. 2.Or use another kind of representation: end 223 minimum point 225 of this contact site 220 and the line L2 of this center of circle P and start from this center of circle P and angle R between the straight line L3 vertically extended is equal to or less than 90 degree downwards.
In the preferred forms of the utility model electric connector 100, the end 223 of this contact site 220 is become an arc section by inflection, make this contact site 220 in bird head, and this arc section is still the center of circle with P; In other embodiments, can inflection be not the arc section in the center of circle with P, also can be other non-radiused; Certainly this end 223 also can not inflection, the only position of the minimum point 225 of control end 223.
Terminal 2 contact site 220 structure of the utility model electric connector 100 is relative to terminal contact portion of the prior art, and end moves down or infolding, all can reduce the risk that this contact site 220 is scraped by outer member.
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.
