Abstract
The utility mode discloses an electric connector terminal for electrically connecting a chip module to a printed circuit board. The electric connector terminal comprises a base part and an elastic part which is upwards extended from the base part; the tail end of the elastic part is provided with a contact part; the bottom end of the base part is provided with a containing part and clamping parts positioned at both sides of the containing part; each holding part is provided with a knife part; the thickness of the knife part is smaller than that of the base part; during the process of assembling solder into the electric connector terminal, the knife part can puncture and pierce into the solder and can be firmly positioned with the solder; and thus the solder is prevented from falling from the electric connector terminal, and the solder can be firmly positioned on the electric connector terminal without welding.
Description
[technical field]
The utility model relates to a kind of electric connector terminal, relates in particular to a kind of electric connector that fixedly positioning scolder.
[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 that flat base portion, the elastic portion that extends upward from base portion reach from the downward extended weld part of base portion.The end of base portion is provided with contact site.Weld part is plate-like structure, and its bottom is welded with scolder.Contact site and chip module electrically connect, and scolder is soldered to printed circuit board (PCB), realize that excellent electrical property is connected between chip module and printed circuit board (PCB).
Yet this electric connector terminal is in the process of using, and the tin ball will be soldered to printed circuit board (PCB), has increased operation, is unfavorable for saving cost.
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 need not weld and can fixedly positioning scolder.
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 base portion and the elastic portion that extends upward from base portion, the end of elastic portion is provided with contact site, the bottom of base portion is provided with the resettlement section and is positioned at the clamping part of both sides, resettlement section, and clamping part is provided with sharp knife portion, and the thickness of sharp knife portion is less than the thickness of base portion.
Compared to prior art, the utility model electric connector terminal has following advantage: be assembled in the process of electric connector terminal at scolder, sharp knife portion can puncture scolder and thrust scolder inside and fixedly positioning with scolder, prevent that scolder from dropping from electric connector terminal, scolder need not weld and can be positioned on the electric connector terminal securely.
[description of drawings]
Fig. 1 is the stereogram of the utility model electric connector terminal first embodiment.
Fig. 2 is the schematic diagram of electric connector terminal shown in Figure 1 and the assembling of tin ball.
Fig. 3 is the schematic diagram of the utility model electric connector terminal second embodiment and the assembling of tin ball.
[embodiment]
See also shown in Figure 1, disclosed the stereogram of the utility model electric connector terminal 1 first embodiment, it is used to electrically connect chip module (not shown) to printed circuit board (PCB) (not shown), comprises flat base portion 10, the location division 12 of extending straight up from base portion 10 tops, self-align the 12 1 extended transition part 13 of lateral buckling and upwards bends extended elastic portion 14 from transition part 13 tops.
The both sides of base portion 10 are provided with hangnail 101, and the bottom of base portion 10 is provided with the resettlement section 113 of accommodating scolder 2 and is positioned at a pair of clamping part 11 of 113 both sides, resettlement section.The bottom of clamping part 11 and a side are provided with sharp knife portion 112, and the sharp knife portion 112 that is positioned at clamping part 11 1 sides extends into resettlement section 113.Base portion 10 is provided with the portion of thrusting 102 that extends into resettlement section 113, thrusts the top that portion 102 is positioned at resettlement section 113.The thickness of sharp knife portion 112 is less than the thickness of base portion 10.In the present embodiment, sharp knife portion 112 forms from clamping part 11 outside convergents, and its end is linear structure.
See also shown in Figure 2ly, scolder 2 is the tin ball, and scolder 2 is assembled into resettlement section 113 from the lower end of electric connector terminal 1.In the process of assembling, sharp knife portion 112 can puncture scolder 2 and thrust scolder 2 inside and fixedly positioning with scolder 2, prevents that scolder 2 from dropping from electric connector terminal 1.In the present embodiment, thrust portion 102 and do not thrust in the scolder 2, this does not constitute any restriction to the utility model, thrusts portion 102 and can thrust in the scolder 2 further to fixedly positioning scolder 2 yet.
Fig. 3 is the another one embodiment of the utility model electric connector terminal 1 ', be with the difference of first embodiment: base portion 10 ' only is provided with sharp knife portion 112 ' in the bottom of clamping part 11 ', be assembled in the process of electric connector terminal 1 ' at scolder 2, sharp knife portion 112 ' can puncture scolder 2 and thrust scolder 2 inside and fixedly positioning with scolder 2, prevents that scolder 2 from dropping from electric connector terminal 1.
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.
