Description

Arrangements of terminal

Technical field

The utility model relates to a kind of arrangements of terminal, and it mainly is to bear portion in the epimere formation one of this terminal, and it is engaged with the spliced eye of pedestal, and the hypomere of this terminal then forms an elastic contact part.

Background technology

ZIF (CPU adapter) the runners terminal construction of general computer CPU (centre device), after the major function of its terminal was to insert the main frame substrate, conducting CPU and substrate circuit made CPU be fixed simultaneously.

Wherein, above-mentioned ZIF runners terminal is the grafting of clamping CPU terminal, it is to avoid the situation of loose contact to take place in the part that contacts with the CPU terminal, it promptly can have the effect that be difficult for to produce elastic fatigue so that the CPU terminal contacts with ZIF runners terminal closely in the back of pegging graft in the part that contacts with the CPU terminal, therefore, when ZIF runners terminal is accepted the CPU terminal, promptly can produce slotting power in a way because of the part that contacts with the CPU terminal on the ZIF runners terminal.

And following in the perfect day by day situation of computer function, the terminal supportor quantity that CPU uses the conduction signal also increases with work, so under the grafting of the CPU with a large amount of terminals, when its slotting power of accumulating promptly can cause assembling, the power that must apply relatively increase, and then also relatively change is big to cause pressure that this XIF runners terminal born.

Therefore, when its in when assembling, the crushing resistance of this ZIF runners terminal is just very important, but, the inserting terminal that this point but is at present general modified form is failed effectively solution.

See also Fig. 1, Fig. 6, as shown in the figure: be to be general XIF runners terminal, the contact feet 21 of this terminal 2 is to be a sheet, so after the terminal supportor 61 of CPU6 is plugged in the spliced eye 71 of upper pedestal 7, combine with terminal 2 in the spliced eye 11 that is plugged on lower base 1 again, wherein, this lower base 1 is the spliced eye 32 that is welded in circuit board 3 by terminal 2, so the slotting power that several spliced eye 11 interior terminals 2 that are plugged on lower base 1 are accumulated promptly can make user's misoperation easily, and then causes the contact feet 21 of the spliced eye 32 that is welded in circuit board 3 to produce distortion and crooked.

In addition, this terminal 2 does not have the elastic space that expansion is shunk, and makes it when assembling is pegged graft, and injures the weld 31 on the circuit board 3 that is connected with terminal 2 easily because of operational careless mistake, and then causes its loose contact.

Summary of the invention

The purpose of this utility model provides the arrangements of terminal of the good crushing resistance of a kind of tool.

Above-mentioned purpose of the present utility model is achieved in that a kind of arrangements of terminal, and it mainly is to bear portion in the epimere formation one of this terminal, and it is engaged with the spliced eye of pedestal, and the hypomere of this terminal then forms an elastic contact part; Wherein: this elastic contact part is the U-shaped body of a bottom continuous bending that is provided with protuberance and in its inner elastic space that forms.

Above-mentioned purpose of the present utility model and 26S Proteasome Structure and Function thereof are elaborated with instantiation below in conjunction with accompanying drawing.

Specific embodiment

The utility model provides a kind of arrangements of terminal, see also Fig. 4, it mainly is to bear portion 41 in the epimere formation one of this terminal 4, and the middle section of its base plate 411 both sides forms a trapezoidal flank 412 respectively, extend and the following L shaped lamellar body 413 of bending forward that is formed with respectively in two flanks 412, and the upper end of two L shaped lamellar bodies 413 forms each lamellar body that extends to central authorities' turnover, and form an elastic contact part 42 in the hypomere of this terminal 4, and this elastic contact part 42 is a U-shaped body 424 that bends continuously, and form an elastic space 421 in the inside of U-shaped body 424, its bottom 423 then is provided with a protuberance 422.

See also Fig. 2, Fig. 4, Fig. 7, as shown in the figure: after the terminal supportor 61 of CPU6 is plugged in the spliced eye 71 of upper pedestal 7, combine with terminal 4 in the spliced eye 91 that is plugged on lower base 9 again, wherein, this lower base 9 is to be welded on the circuit board 8 with SMT (surface mounted) by terminal 4, and then this is provided with the terminal 4 of elastic contact part 42, forms when electrically connecting in itself and circuit board 8, this elastic space 421 can reach measuring body effect, and then avoids the weld 81 of circuit board 8 to suffer damage.

See also Fig. 5, another embodiment for this creation, as shown in the figure: it mainly is to bear portion 51 in the epimere formation one of this terminal 5, and the middle section of its base plate 511 both sides forms a trapezoidal flank 512 respectively, extend and the following L shaped lamellar body 513 of bending forward that is formed with respectively in two flanks 512, and the upper end of two L shaped lamellar bodies 513 forms each lamellar body that extends to central authorities' turnover, and form an elastic contact part 52 in the hypomere of this terminal 5, and this elastic contact part 52 is a semi arch body 523 that bends continuously, and forms an elastic space 522 in the inside of semi arch body 523.
