Description

Electric connector terminal

[technical field]

The utility model relates to a kind of electric connector terminal, relates in particular to a kind of electric connector terminal that electrically connects the chip module to printed circuit board (PCB).

[background technology]

A kind of electric connector terminal relevant with the utility model, it is used to electrically connect the chip module to printed circuit board (PCB), comprises the first terminal, second terminal and the elastic component between the first terminal and second terminal.The first terminal comprises flat base portion, base portion is provided with first contact site that electrically connects with the chip module, second terminal comprises flat main part and the upwardly extending a pair of arm of autonomous body, and main part is provided with second contact site that electrically connects with printed circuit board (PCB).Base portion and main part are provided with the limiting section of restriction elastic component respectively, and this limiting section can prevent that elastic component upwards breaks away from the first terminal and breaks away from second terminal downwards.Base portion contacts between a pair of arm and with arm, and when the chip module pressed down the first terminal, arm and base portion vertically relatively moved and keep in touch state always, makes to realize between chip module and the printed circuit board (PCB) that excellent electrical property is connected.

Because the first terminal only relies on the chucking power and second terminal of the arm of second terminal to reach electric connection, in use, if chucking power is not enough, the first terminal and second terminal is disengaged, and influences the contact quality of electric connector terminal.

Therefore, be necessary to design a kind of new electric connector terminal to overcome the defective that above-mentioned electric connector terminal exists.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector terminal, and it has strengthened the effect that contacts between the first terminal and second terminal effectively.

For achieving the above object, the utility model adopts following technical scheme: a kind of electric connector terminal, be used to electrically connect the chip module to printed circuit board (PCB), comprise the first terminal, second terminal and the elastic component between the first terminal and second terminal, the first terminal comprises the base portion that main part and autonomous body extend downwards, main part is provided with first contact site, base portion is provided with first surface and reaches and the first surface opposing second surface, second terminal is provided with the arm that contacts with first surface, and first contact site is obliquely installed to second surface from first surface.

Compared to prior art, the base portion of the first terminal of the utility model electric connector terminal is provided with first surface and reaches and the first surface opposing second surface, second terminal is provided with the arm that contacts with first surface, first contact site is obliquely installed to second surface from first surface, when the chip module presses down first contact site, its base portion tilted to the arm direction of second terminal when the first terminal moved down, and made to keep the excellent contact state between base portion and the arm.

[embodiment]

See also Fig. 1 to shown in Figure 3, the utility model electric connector terminal 100 is used to electrically connect chip module (not shown) to printed circuit board (PCB) (not shown), comprise the first terminal 1, second terminal 2 and be arranged on the first terminal 1 and second terminal 2 between elastic component 3.

The first terminal 1 comprises the base portion 11 that flat main part 10 and autonomous body 10 extend downwards, and the thickness of main part 10 is greater than the thickness of base portion 11.The top of main part 10 is provided with first contact site 101 that electrically connects with the chip module, and main part 10 has extended to form a pair of first stop part 102 near two side position along continuous straight runs of base portion 11.The bottom of base portion 11 is provided with holding part 112, base portion 11 is provided with first surface 110 and makes first contact site 101 first surface 110 and second surface 111 between have difference in height from first surface 110 to second surface 111 diagonally extendings with first surface 110 opposing second surface 111, the first contact sites 101.

Second terminal 2 comprises that flat head 20 reaches from head 20 upwardly extending a pair of arms 21.The top of a pair of arm 21 is respectively equipped with toward each other the hook portion 211 of extending, and these hook portions 211 contact with second surface 111 with the first surface 110 of the base portion 11 of the first terminal 1 respectively.The bottom of head 20 is provided with second contact site 202 that electrically connects with printed circuit board (PCB), and head 20 has extended to form a pair of second stop part 201 near two side position along continuous straight runs of arm 21.The top of elastic component 3 is subjected to the keeping out of first stop part 102 of the first terminal 1, prevents that elastic component 3 breaks away from from the first terminal 1, and the bottom of elastic component 3 is subjected to the keeping out of second stop part 201 of second terminal 2, prevents that elastic component 3 breaks away from from second terminal 2.

Please consult shown in Figure 3ly simultaneously, the utility model electric connector terminal 100 is in initial condition, and the holding part 112 of hook portion 211 and the first terminal 1 of second terminal 2 interlocked and held this moment, prevented the

first terminal

1 and 2 disengagings of second terminal.

Please consult shown in Figure 4ly simultaneously, when the tin ball 4 of chip module pressed down the first terminal 1, the first terminal 1 can move down compression elastic piece 3 simultaneously.In this process, base portion 11 moves down along arm 21, and its first surface 110 keeps in touch state with second surface 111 and hook portion 211, so that realize that excellent electrical property is connected between chip module and printed circuit board (PCB).Because first contact site 101 makes first contact site 101 have difference in height from first surface 110 between first surface 110 and second surface 111 to second surface 111 diagonally extendings, when moving down, base portion 11 can tilt, to guarantee excellent contact state between base portion 11 and the arm 21 to arm 21.After the chip module was removed, the reaction force that the first terminal 1 is subjected to elastic component 3 was moved upward to initial condition, and the holding part 112 of the hook portion 211 of second terminal 2 and the first terminal 1 interlocks and holds at this moment.

The emphasis structure of the utility model electric connector terminal 100 is: there is difference in height in first contact site 101 of the first terminal 1 of electric connector terminal 100 between the first surface 110 of base portion 11 and second surface 111, when the chip module presses down first contact site 101, the base portion 11 of the first terminal 1 tilts to the direction of the arm 21 of second terminal 2, makes between the hook portion 211 of base portion 11 and arm 21 to keep contact condition closely.

Should be understood that, the above only is a preferred forms of the present utility model, it or not whole execution modes, 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.
