Abstract
The utility model relates to a terminal for electric connector to electrically connect wafer module to circuit board, which comprises a vertically extended holder, a welding portion electrically connected with the circuit board, a contact part bended and extended upwards on one side of the holder and a connecting part to connect the holder with the welding portion. Wherein, the connecting part is provided with a torsion area to provide three-dimensional flexibility for the terminal, effectively avoid tinned ball burst and strengthen electric contact stability.
Description
[technical field]
The utility model relates to a kind of electric connector terminal, especially refers to electrically connect the electric connector terminal of wafer module to circuit board.
[background technology]
As depicted in figs. 1 and 2, a kind of existing electric connector terminal 100 ' can electrically connect wafer module 40 ' to circuit board 60 ', it comprise with wafer module 40 ' electrically contact contact site 31 ', the holding parts 32 ' that extends in vertical direction, be welded with tin ball 50 ' with weld part 34 ' that electrically connects circuit board 60 ' and the connecting portion 35 ' that is connected weld part 34 ' and holding parts 32 '.Holding parts 32 ' is provided with some projections 321 ' and interferes with insulating body 20 ' and cooperate, to fix this electric connector terminal 100 '.Connecting portion 35 ' is that rounding off is to weld part 34 ', between connecting portion 35 ' and weld part 34 ', form an arc thus, offer electric connector terminal 100 ' flexible on Z ' direction (Z ' direction be meant the bearing of trend of holding parts 32 ') and the Y ' direction (Y ' direction be meant the bearing of trend of weld part 32 ') in diagram.
Yet, when electric connector terminal 100 ' is done environmental testing, circuit board 60 ' is so that whole measurement jig (not shown) all can produce the power of upholding or compressing to tin ball 50 ', simultaneously, tin ball 50 ' also can be subjected to the stress of electric connector terminal 100 ', wherein tin ball 50 ' is stressed from Y ' in the diagram, Z ', making a concerted effort of X ' (X ' direction is meant and Y ' direction and Z ' direction constitute the vertical direction in plane) three directions, and electric connector terminal 100 ' only has flexible on Z ' direction and Y ' direction, promptly can reduce tin ball 50 ' stressed on Z ' direction and Y ' direction, and it is no flexible on X ' direction, so when stressed bigger on X ' direction, tin ball 50 ' will break, and influences the electric connection of electric connector terminal 100 '.
Given this, be necessary to provide a kind of improved electric connector terminal in fact, to overcome the defective of above-mentioned electric connector terminal.
[utility model content]
Technical problem to be solved in the utility model provides a kind of electric connector terminal of tool good characteristics of flexibility.
For solving the problems of the technologies described above, it is a kind of in order to electrically connect the electric connector terminal of wafer module to circuit board that the utility model provides, it is included in holding parts that vertical direction extend to be provided with, on holding parts one side direction the bending extension setting with the contact site that electrically connects the wafer module, the weld part that electrically connects circuit board, and the connecting portion that connects weld part and holding parts, wherein, connecting portion is provided with and reverses the zone.
Compared with prior art, the utility model has the following advantages at least: be provided with at the electric connector connecting portion and reverse the zone, change electric connector terminal and only on holding parts bearing of trend and weld part bearing of trend, had flexible defective, offer flexible on the electric connector terminal stereoscopic three-dimensional direction, can reduce the stressed of tin ball thus, avoid breaking of tin ball, realize the firm connection of electric connector terminal.
[description of drawings]
Fig. 1 is the cross-sectional schematic after a kind of existing electric connector terminal is assembled in insulating body, and wherein electric connector terminal does not dock with the wafer module as yet.
Fig. 2 is the schematic perspective view of electric connector terminal shown in Figure 1.
Fig. 3 is the schematic perspective view of the utility model electric connector terminal.
[embodiment]
Please join shown in Figure 3, the utility model electric connector terminal 100 is in order to electrically connect wafer module (not shown) to circuit board (not shown), the weld part 34 that it comprises the contact site 31 that electrically connects with the wafer module, extends the holding parts 32 that is provided with, electrically connects with circuit board in vertical direction, and the connecting portion 35 that connects holding parts 32 and weld part 34.
Near bending extension on wafer module one side direction, its free terminal is provided with contact area 311 to contact site 31, electrically to contact with the wafer module from holding parts 32.
Connecting portion 35 comprises the base portion 351 that extends out from holding parts 32 lower ends, reverse zone 352 and reversing transitional region 353 between zone 352 and the weld part 34.Wherein reverse the diverse location that zone 352 can be arranged on connecting portion 35 according to actual needs, torsional direction can be set to clockwise direction, also can be set to counterclockwise, thus, reverses zone 352 and can offer electric connector terminal 100 flexible on directions X.In addition, the width that reverses zone 352 can be adjusted into different sizes with actual conditions, and a plurality of zones 352 of reversing also can be set on connecting portion 35.Transitional region 353 be rounding off to weld part 34, and the plane that constituted perpendicular to weld part 34, the plane that constituted of transitional region 353, thus, transitional region 353 offers electric connector terminal 100 flexible on Y direction and Z direction.Like this, electric connector terminal has just possessed flexible on X, Y, the Z three-dimensional.
When doing environmental testing, the stress that circuit board and even whole testing making apparatus (not shown) have extension or compress the tin ball, electric connector terminal 100 also can have individual counter-force to the tin ball, but because this moment, electric connector terminal 100 possessed flexible on X, Y, the Z three-dimensional, so can reduce the stressed of tin ball, avoid breaking of tin ball, realize that electric connector terminal 100 firmly electrically connects.
Should be pointed out that the above a kind of execution mode of the present utility model that only is, other any equivalent transformation that carries out on this execution mode basis does not break away from essence technical scheme of the present utility model.
