Abstract
The utility model relates to an electric connector terminal which is used to electrically connect a wafer module and a printed circuit board, comprising a basal portion with a barb, a terminal waist portion and a welding portion which are respectively extend from both sides of the basal portion, an elastic arm portion which is formed by upward bending and extending from the terminal waist, and a connecting portion which connects the terminal waist portion and the elastic arm portion, wherein the widths of the terminal waists portion of the electric connector is inconsistent. The design of the utility model can scatter the stress which is caused by the elastic deformation of the elastic arm, and reduce the central stress of the connecting position, thereby increasing the service life the terminals of the electric connector.
Description
[technical field]
The utility model refers in particular to the electric connector terminal that electrically connects wafer module and printed circuit board (PCB) about a kind of electric connector terminal.
[background technology]
Electric connector is widely used in electronic applications, in order to the wafer module is electrically connected to circuit board, with the transmission of signal and data between realization wafer module and circuit board.Shape and structure according to wafer module conducting element, electric connector generally can be divided into needle-like grid array (Pin Grid Array again, 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.
A kind of electric connector terminal 1 that Fig. 1 discloses for prior art ', it comprise base portion 10 with hangnail ', the terminal waist 11 that extends from base portion 10 ' both sides respectively ' and weld part 12 ', the elastic arm 13 that extends to form from the bending of terminal waist 11 ' upwards ' and splicing ear waist 11 ' with elastic arm 13 ' connecting portion 14 ', terminal waist 11 ' be wide setting wherein.During use, electric connector terminal 1 ' base portion 10 ' be immobilizated in the insulating body (not shown), its elastic arm 13 ' the smooth circular arc contact site 131 that is provided with of free terminal ' and weld part 12 ' respectively and wafer module on conducting element, the phase of solder joint butt joint on the printed circuit board (PCB), thereby realize the electric connection of wafer module and printed circuit board (PCB).
In actual use, when the wafer module by the mode of pushing and electric connector terminal 1 ' when electrically contacting, electric connector terminal 1 ' elastic arm 13 ' elastic deformation will take place, the stress of its generation concentrates on the connecting portion 14 of terminal ' locate, therefore, excessive or stressed when being accumulated to a certain degree at the pressing force of electric connector terminal 1 ' suffered, this connecting portion 14 ' very easily rupture because of overtired.
In view of above drawback, be necessary to design a kind of electric connector terminal really at above-mentioned shortcoming.
[utility model content]
The purpose of this utility model provides a kind of electric connector terminal that disperses concentrated stress, to prolong its useful life.
For this reason, the utility model design provides the electric connector terminal of a kind of connecting wafer module and printed circuit board (PCB), it comprises: have the base portion of hangnail, the terminal waist that extends from the base portion both sides respectively and weld part, from terminal the waist upwards elastic arm that extends to form of bending and splicing ear waist and elastic arm's connecting portion, wherein the width of terminal waist is inconsistent.
With respect to prior art, the utility model design electric connector terminal has the following advantages: the waist width of electric connector terminal is inconsistent, can disperse because the stress that elastic arm generation elastic deformation produces, reduce the concentrated stress at connecting portion place, thereby improved the useful life of electric connector terminal.

Fig. 2 is the schematic perspective view of the utility model electric connector terminal.
Fig. 3 is the schematic diagram at another visual angle of electric connector terminal shown in Figure 2.
[embodiment]
Engage the concrete structure that accompanying drawing describes the utility model electric connector terminal 1 in detail below.
See also Fig. 3, the utility model electric connector terminal 1 is used for electrically connecting wafer module (not shown) and printed circuit board (PCB) (not shown), and it mainly comprises: plate-like base 10 of extending in vertical direction and the terminal waist 11 that extends to two ends from base portion 10, weld part 12 and from terminal waist 11 elastic arm 13 that extends to form of bending upwards.
Base portion 10 is en plaque and stretched flat vertically between wafer module and printed circuit board (PCB), there are some hangnails 101 position in its both sides near weld part 12, so that with insulating body (not shown) interference engagement, weld part 12 is the near normal setting with base portion 10 bendings.Elastic arm 13 and terminal waist adopt circular arc connecting portion 14 to be connected, and elastic arm 13 free terminal is provided with smooth circular arc contact site 131, with the wafer module on the contact (not shown) of corresponding conducting element dock.
Because the waist 11 of the utility model electric connector terminal 1 has adopted non-wide design, so in use, compare with existing electric connector terminal, when being subjected to onesize power or perhaps experiencing equally repeatedly the accumulation of power, the stress distribution that the stress at connecting portion 14 places is partly transferred to terminal waist 11 places and connecting portion place is even, thereby can strengthen its anti-fatigue performance, improve the useful life of electric connector terminal 1.
