The protrusion is positioned below the welding part, with a certain distance therebetween.
Description
[technical field]
The utility model relates to a kind of electric connector terminal, refers to a kind of electric connector terminal that the wafer module is electrically connected to circuit board especially.
[background technology]
Fig. 1 is a kind of stereogram of the electric connector terminal relevant with the utility model.This kind electric connector terminal is applied in zero insertion force (ZIF) the type electric connector, correlation technique as " Development ofZIF BGA Socket " (Connector Specifier, February 2002) in announcement is arranged, United States Patent (USP) the 6th, 319,038,6,375, also disclosed this class formation No. 485.
See also Fig. 1, this electric connector terminal 1 comprise base portion 11 and from base portion 11 to the extended arm 12 of two lateral bucklings, there is a small embossment 110 at base portion 11 middle parts, the end of arm 12 is hangnail portions 120.Extend upward and bend out linking part 121 and weld part 13 from one of them arm 12 end, weld part 13 middle parts are provided with the depression 130 that is used for welding the tin ball.Extend adjutage 14 downwards from arm 12, be the least significant end that splay haptic element 15 is positioned at adjutage 14.Electric connector terminal 1 will be electrically conducted circuit board by the tin ball (not shown) with weld part 13 welding, electrically connect by the stitch of haptic element 15 with the wafer module.
With electric connector terminal 1 and insulating body (not shown) when being assembled into electric connector, promptly electric connector terminal 1 is pressed in the process of insulating body terminal groove, and these electric connector terminal 1 many places are stressed.As shown in Figure 1, be subjected to be pressed into straight down power F, be subjected to the power f reverse respectively with F at small embossment 110 and two hangnail portion 120 places of interfering with insulating body on base portion 11 tops

2, f
3As can be seen from the figure, stressed middle F in three places and f
1Very approaching, and f

3The torque M that produces might cause electric connector terminal 1 to be toppled in the process that is pressed into, thus the reliability of influence assembling.The requirement of this reliability in actual production is very high, and the corresponding numbers of terminals of large-scale wafer module has hundreds of even thousands of individual, as long as the above-mentioned situation of indivedual appearance wherein all will have a strong impact on product quality and working (machining) efficiency.
Given this, be necessary to provide a kind of new electric connector terminal to address the above problem in fact.
[utility model content]
The technical problems to be solved in the utility model provides a kind of electric connector terminal, and it can prevent to topple over when being pressed into insulating body.
The utility model solves the problems of the technologies described above like this: the arm end that is not provided with linking part at electric connector terminal is provided with the protuberance that points to weld part, this protuberance is positioned at weld part below and the two is slightly gapped, assembling adds simultaneously increases by place's point of application at weld part man-hour, and this newly-increased point of application and the former power of the being pressed into point of application lay respectively at by aforementioned torque and cause the centre of gyration line both sides of toppling over.
Compared with prior art, the utlity model has following advantage: after having increased the protuberance and the point of application, terminal is active force and reaction force balance more when being pressed into insulating body, torque by its generation also obtains balance, thereby effectively prevents the phenomenon that electric connector terminal is toppled over when being pressed into insulating body.

[embodiment]
The utility model electric connector terminal 1 is mainly used in wafer module (not shown) is electrically connected to circuit board (not shown), shown in Fig. 3,4,
Fig. 2 is the utility model electric connector terminal 2, this electric connector terminal 2 comprise base portion 21 and from base portion 21 to the extended arm 22 of two lateral bucklings, there is a small embossment 210 at base portion 21 middle parts, the end of arm 22 is hangnail portions 220.Extend upward and bend out linking part 221 and weld part 23 from one of them arm 22 end, weld part 23 middle parts are provided with the depression 230 that is used for welding the tin ball; Be not provided with at another that arm 22 of linking part is terminal to be provided with the protuberance 222 that points to weld part 23 with connecting portion opposite position, this protuberance 222 is positioned at weld part 23 belows and the two is slightly gapped.Extend adjutage 24 downwards from arm 22, be the least significant end that splay haptic element 25 is positioned at adjutage 24.Electric connector terminal 2 will be electrically conducted circuit board by the tin ball (not shown) with weld part 23 welding, electrically connect by the stitch of haptic element 25 with the wafer module.
Wherein protuberance 222 is roughly rectangular, and end face is a plane, has a determining deviation between the bottom surface of end face and weld part 23.End face is that a plane can form bigger contact area with it when weld part 23 stressed pressing down, and reduces the distortion of pressure and compression-side protuberance 222 and arm 22.As for a determining deviation that exists between the two, then mainly be to consider difficulty of processing and cost, the two be close to no gap not impact effect but giving to make to go up increases bigger difficulty, leave certain spacing so design under the prerequisite of impact effect not.
With electric connector terminal 2 and insulating body (not shown) when being assembled into electric connector, promptly electric connector terminal 2 is pressed in the process of insulating body terminal groove, and these electric connector terminal 2 many places are stressed.As shown in Figure 2, be subjected to be pressed into straight down power F on base portion 21 tops
1, weld part 23 is subjected to be pressed into straight down power F
2, be subjected to respectively and F at small embossment 210 and two hangnail portion 220 places of interfering with insulating body
1, F
2Reverse power f

3Effect is down with oriented F
1The trend that one lateral deviation is changeed is torque M shown in the figure
23, because the newly-increased power F that is pressed into
2The point of application and the former power of being pressed into F
1The point of application lays respectively at by aforementioned torque and causes the centre of gyration line both sides of toppling over, therefore by f
