Embodiment
Below in conjunction with specific embodiment and accompanying drawing, chip program download apparatus of the present invention is described in further detail.
Refer to Fig. 1, a kind of chip program download apparatus, it comprises a download apparatus main body 10 substantially in rectangular parallelepiped, multiple parallel arranged and vertically run through the binding post 30 of download apparatus main body upper and lower surface, the scalable contact pin 40 be fastenedly connected with binding post 30 bottom respectively and the snap close 20 being symmetricly set on download apparatus main body about 10 two ends respectively.
Understandable, for making chip program download apparatus better be placed in the corresponding DLL (dynamic link library) of circuit board upgrading chip, binding post 30 is basic vertical with the lower surface of main body 10.
Snap close 20 and download apparatus main body 10 run through download apparatus main body 10 forward-and-rearward pin 50 respectively by one and carry out hinge type and be connected, and snap close 20 can rotate around pin 50.
The two ends, left and right of a sidewall of download apparatus main body 10 are symmetrically formed one respectively and run through download apparatus main body 10 forward-and-rearward first through hole 11, and this first through hole 11 roughly in cylindric, and can pass for pin 50.
The upper surface of download apparatus main body 10 is symmetrically formed respectively two be restricted snap close 20 rotate block 12.
The upper surface of download apparatus main body 10 is also formed with multiple parallel arranged and vertically runs through the third through-hole 13 of download apparatus main body 10 upper and lower surface, this third through-hole 13 can pass for binding post 30, understandable, be interference fit between binding post 30 and third through-hole 13, can be fasteningly arranged in third through-hole 13 to make binding post 30.
Refer to Fig. 2, snap close 20 comprises two parallel arranged and roughly in the sway brace 21 of " Z " shape, the lower surface that the first paragraph of this sway brace 21 is arranged on the upper surface of download apparatus main body 10, second segment is vertically arranged, the 3rd section is parallel to download apparatus main body 10 and towards the outside of download apparatus main body 10, the top end of same one end of these two sway braces 21 is connected in one with the two ends of the railing 22 of a column respectively.By the rotation of snap close 20, this railing 22 can ride over the upper surface of download apparatus main body 10, and inconsistent with block 12.The position that two sway braces 21 are corresponding is formed respectively one can for pin 50 through and roughly cylindrical second through hole 23.Length between two sway brace 21 opposed inner walls is not less than the length of the first through hole 11.Refer to Fig. 3, be connected between snap close 20 with download apparatus main body 10 by pin 50, and snap close 20 can rotate around pin 50, when rotation is conflicted to railing 22 with the inner side of block 12, rotate and stop, snap close 20 realizes locking.
Preferably, in the present embodiment, for ensureing electric conductivity timely, the binding post that this chip program download apparatus uses and the equal tool of described scalable contact pin adopt the metal material with electric conductivity to make.
When reality uses, refer to Fig. 4, first the outside of the snap close at two ends, left and right respectively to download apparatus main body 10 is rotated, again the DLL (dynamic link library) that scalable contact pin 40 is corresponding to chip that circuit board 60 is upgraded is alignd one by one, then to take advantage of a situation insertion, the external host computer that can send debug command to chip on circuit board 60 in top of binding post 30.Understandable, instrument case bonnet is formed the groove 71 matched with download apparatus main body 10, groove 71 is corresponding with 60 the upgrade positions of chip on circuit board, the bottom of groove 71 be formed with scalable contact pin 40 on chip program download apparatus with can for sway brace 21 the 3rd section take advantage of a situation through through hole, this through hole is corresponding to the position of the corresponding DLL (dynamic link library) of chip that circuit board 60 is upgraded.When reality uses, first the outside of the snap close 20 at two ends, left and right respectively to download apparatus main body 10 is rotated, again the DLL (dynamic link library) that scalable contact pin 40 is corresponding to chip that circuit board 60 is upgraded is alignd one by one, then to take advantage of a situation insertion, it is last that by two snap closes 20, inwardly rotation is inconsistent with the inner side of block 12 to railing 22 again, now, chip program download apparatus installation.During dismounting, outwards pulled by snap close 20 first respectively to railing 22 and block 12 and depart from, then take advantage of a situation and to be extracted by chip program download apparatus, dismounting completes.
To sum up, the scalable contact pin of chip program download apparatus of the present invention by arranging multiple binding post and be fastenedly connected with binding post respectively in download apparatus main body, can plug and play upgrade in the corresponding DLL (dynamic link library) of chip at circuit board, time saving and energy saving; Be symmetrical arranged snap close at the two ends, left and right of download apparatus main body respectively and the pin of snap close and download apparatus main body can be run through simultaneously, form hinge type to make snap close and download apparatus main body to be connected, can by the locking of chip program download apparatus on the housing of circuit board outside.Can realize the weldless connection between circuit board by this chip program download apparatus, ensure that the quality of circuit board, and structure is simple, easy for installation.
Although the description of this invention carries out in conjunction with above specific embodiment, those skilled in the art can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all like this substitute, improve and change be all included in the spirit and scope of attached claim.
