Fig. 3 is embodiment of the invention bonder terminal sketch map, and is as shown in Figure 3, and the bonder terminal of the embodiment of the invention comprises: first pin 31 and second pin 32.
One end of first pin 31 and second pin 32 all is fixed on the connector 33.The length of first pin 31 is H1, and the length of second pin 32 is H2.The length of pin is meant point that pin and golden finger contact the at first distance to connector in the embodiment of the invention.As shown in Figure 3 again, first pin 31 is different with the length of second pin 32; Be that H1 and H2 are unequal.The length H1 of first pin 31 of embodiment of the invention bonder terminal is greater than the length H2 of second pin 32.
Length difference between first pin 31 and second pin 32 is H1-H2=L.The size of L value confirms that according to actual conditions the L value can not be too big, because the L value is big more, the length difference of first pin and second pin is big more, and the contact reliability of two pins and golden finger is poor more; The L value can not be too little; Length difference between more little two pins of L value is more little; Make that the processing technology precision is high, difficulty is big, the while pin is easy abrasion in use, if the L value is too little; It is the same with second pin long to occur first pin after the wearing and tearing, thereby causes realizing the printed circuit board (PCB) hot plug.The L value is general to be confirmed according to the position difference between longer golden finger and the shorter golden finger in the golden finger of industry making at present.
Fig. 4 is the outside golden finger sketch map of embodiment of the invention bonder terminal, and as shown in Figure 4, the upper and lower surfaces of printed circuit board (PCB) 12 all is provided with golden finger 13, and the length of golden finger 13 is different, and wherein the length of golden finger D is the longest, and golden finger B length is shorter.Golden finger D and golden finger B have signal, are used for the information transmission.Golden finger C does not have signal, and just protective money finger B also can remove golden finger C in actual the setting.As shown in Figure 4 again, the alternate position spike between golden finger D and the golden finger B is L, and promptly the length difference between golden finger D and the golden finger B is L.Alternate position spike L between golden finger D and the golden finger B; Mainly be in order to make printed circuit board (PCB) in the process of inserting connector; Two pins of bonder terminal are different with the time of contact between the golden finger; Pin contacts with golden finger D earlier, and then contacts with golden finger B, thereby realizes the hot plug of printed circuit board (PCB).
Existing printed circuit board (PCB) is realized the hot plug of printed circuit board (PCB) through the alternate position spike L between golden finger D and the golden finger B.The length of the golden finger up and down of printed circuit board (PCB) is identical in the embodiment of the invention, but the length of two bonder terminals is different, can realize the hot plug of printed circuit board (PCB) equally.Concrete, let first pin, 31 corresponding golden finger D, second pin, 32 corresponding short golden finger B.In the prior art, first pin 31 is identical with second pin, 32 length, and golden finger D and golden finger B length differ L; In the embodiment of the invention; Let golden finger B length prolong L, promptly golden finger B becomes golden finger D, and second pin 32 that will be corresponding with golden finger B shortens L; Such two pins contact with golden finger and still have the time difference successively, thereby realize the hot plug of printed circuit board (PCB).
Need to prove, in the embodiment of the invention two pin difference L generally according to AMC, Advanced Mezzanine Card; The alternate position spike of golden finger D and golden finger B is confirmed in the enlargement module standard of the ATCA of a new generation platform; In the AMC standard, the alternate position spike of golden finger D and golden finger B can be 1.15mm, or is 1.45mm; Then the difference L between two of embodiment of the invention bonder terminal pins can be 1.15mm, also can be 1.45mm.The explanation that needs be that the difference L between two pins of embodiment of the invention bonder terminal also can adopt other numerical value according to actual conditions, contacts the existence priority time difference with golden finger as long as can satisfy two pins.
