Abstract

The utility model relates to a terminal for electric connector to electrically connect with a wafer module with PCB, which comprises a vertically extended plate-like holder, arms respectively extended from both sides of the holder, a welding portion and a neck between the holder and welding portion. Wherein, the neck is provided with a C-shaped area, which increases length and flexibility of the neck to reduce tinned ball fracture of electric connector on the terminal or PCB side due to high and low-temperature circulation for the connector environmental test.

Description

Electric connector terminal

[technical field]

The utility model relates to a kind of electric connector terminal, refers to a kind of electric connector terminal that is used to electrically connect wafer module and printed circuit board (PCB) especially.

[background technology]

Electric connector is widely used in the various electronic equipments, be used to electrically connect wafer module and printed circuit board (PCB), shape and structure according to wafer module conducting element, electric connector generally can be divided into needle-like grid array (Pin Grid Array, PGA) connector, ball-shaped grid array (Ball Grid Array, BGA) connector and planar lattice array (Land Grid Array, LGA) connector.Accordingly, the conducting terminal that is located in the electric connector also is divided into PGA type terminal, BGA type terminal and LGA type terminal.

Fig. 1 is a kind of electric connector terminal 1 ' that prior art disclosed, its general structure comprises: in the tabular holding parts 10 ' of vertical direction extension, the arm 11 ' and the weld part 12 ' that extend from holding parts 10 ' both sides respectively, and the connecting portion 13 ' that connects holding parts 10 ' and weld part 12 ', wherein, described connecting portion 13 ' is smooth circular arc, arm 11 ' free terminal is provided with contact site 110 ' to electrically connect with wafer module (not shown), weld part 12 ' bottom is provided with tin ball (not shown), and this tin ball can electrically connect electric connector terminal 1 ' to printed circuit board (PCB) (not shown).

Yet there is following shortcoming at least in the electric connector terminal 1 ' of this kind structure: when this electric connector terminal 1 ' is carrying out in the cyclic process of environmental testing high temperature low temperature, because the connecting portion 13 ' of this bonder terminal 1 ' is too short, to cause the amount of deflection of terminal 1 ' too poor, thereby make the tin ball of terminal 1 ' side or the tin ball of printed circuit board side rupture.

In view of above drawback, necessaryly provide a kind of electric connector terminal, to overcome above-mentioned shortcoming and defect of the prior art.

[summary of the invention]

Technical problem to be solved in the utility model provides a kind of electric connector terminal, and it can reduce or avoid the phenomenon of tin ball fracture.

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 and printed circuit board (PCB) that the utility model provides, it comprises: the tabular holding parts of Yan Shening vertically, arm and the weld part that extends from the holding parts both sides, and the neck between holding parts and weld part respectively.Wherein, neck is provided with a C shape zone.

Compared with prior art, the utility model electric connector terminal has the following advantages: neck C shape zone the length that has increased neck is set, strengthened the amount of deflection of electric connector terminal, thus make this electric connector terminal in the circulation of carrying out environmental testing high temperature low temperature, be easy to by.

[embodiment]

Describe the embodiment of the utility model electric connector terminal 1 in detail below in conjunction with accompanying drawing.

See also Fig. 2, the utility model electric connector terminal 1, in order to electrically connect wafer module (not shown) and printed circuit board (PCB) (not shown), its structure generally comprises: the tabular holding parts 10 of Yan Shening vertically, arm 11 and the weld part 12 that extends from holding parts 10 both sides, and the neck 13 between holding parts 10 and weld part 12 respectively.

Holding parts 10 is platy structure, and between wafer module and printed circuit board (PCB) bending extension vertically, its end free terminal near weld part 12 is provided with hangnail district 100 and cooperates and be immobilizated in wherein to interfere with insulating body (not shown).

Arm 11 is bent upwards extension from an end of holding parts 10, and its free terminal is provided with contact site 110 electrically to contact with the wafer module, is smooth circular arc setting between contact site 110 and the holding parts 10, to reduce concentrated stress.

Weld part 12 extends downwards and relative with arm 11 from the other end of holding parts 10, this plane, weld part 12 place and vertical setting the in plane, holding parts 10 place, and its underpart is welded with tin ball (not shown), and realizes and the electric connection of printed circuit board (PCB) by this tin ball.

Neck 13 is for connecting the part of holding parts 10 and weld part 12, and it comprises base portion 130, from the C shape zone 131 that base portion 130 upwards forms, and the transition part 132 that connects hangnail district 100 and C shape zone 131.The length that the neck 13 that extended is set in this C shape zone 131, the while has also increased the amount of deflection of electric connector terminal 1 neck 13, and product also is difficult for rupturing at the circulation time that carries out environmental testing experience high temperature low temperature like this.

In sum, the setting in the utility model electric connector terminal 1 neck 13C shape zone 131 has increased the length of neck 13, has improved the amount of deflection of neck 13 simultaneously, makes product at the circulation time that carries out environmental testing high temperature low temperature, easier passing through.

The above only is a kind of execution mode of the present utility model, it or not whole or unique execution mode, the variation of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
