[embodiment]
As shown in Figure 1 to Figure 3, card edge connector combination of the present invention comprises accommodating the first bayonet connector 1 and second bayonet connector 2 of electronic cards.In the present embodiment, the first bayonet connector 1 is a kind of standard DDR SODIMM connector be used in notebook computer, and the second bayonet connector 2 is a kind of reverse DDR SODIMM connectors that are used in notebook computer.Certainly, in other embodiments, the first bayonet connector 1 and the second bayonet connector 2 can be also the bayonet connectors of other types.In the description of the following concrete structure to the first bayonet connector 1 and the second bayonet connector 2, be all to carry out in the face of the front side of the first bayonet connector 1 and the second bayonet connector 2 with forward.
The first bayonet connector 1 comprises insulating body 11, is arranged at the support arm 12 at insulating body 11 two ends and is contained in the conducting terminal 14 in insulating body 11.Insulating body 11 is by insulating material injection mo(u)ldings such as plastic cement, and its inside is provided with central slot 115 to accommodate the leading edge of electronic cards along longitudinally, and central slot 115 misplugs when preventing that electronic cards from installing also being provided with knob of key 13 near the right support arm 12 places.Conducting terminal 14 is divided into two rows, and the both sides up and down that are contained in respectively central slot 115 are with the contact electronic cards.The welding foot of conducting terminal 14 is the needle-like leg, thereby this will dwindle the first bayonet connector 1 of the space discount something or somebody to fall back on setting that conducting terminal 14 takies below insulating body 11 and the distance between the second bayonet connector 2 can be dwindled.Certainly, the welding foot of conducting terminal 14 can be also other structures, for example ball structure.In the present embodiment, support arm 12 is formed by plastic material, and certainly, in other embodiments, support arm 12 also can be formed by metal material.Support arm 12 extends to form forward from body 11 two ends of insulating, the stop arm 122 that it comprises the clasp arm 121 of inner setting and is positioned at clasp arm 121 outsides.Clasp arm 121 provides the clasp effect when electronic cards is installed, and stop arm 122 can stop clasp arm 121 excessively outwards mobile.The two ends of insulating body 11 also extend back and form the protuberance 110 be oppositely arranged, and form a receiving space 112 between protuberance 110.The bottom of insulating body 11 forms reference column 111 so that positioning action to be provided when installing on circuit board at the first bayonet connector 1 in the downward projection of the correspondence position of protuberance.
The structural similarity of the structure of the second bayonet connector 2 and the first bayonet connector 1, it comprises insulating body 21, is arranged at the support arm 22 at insulating body 21 two ends and is contained in the conducting terminal 24 in insulating body 21.The bottom of insulating body 21 does not arrange reference column.Thereby insulating body 21 is provided with a pair of depressed part 210 in the contrary side of support arm 22 allows the rear side of insulating body 21 be outside projection state.
As shown in Figures 2 to 4, be provided with installing hole 31 on circuit board 3, at card edge connector combination when installing on circuit board 3, at first the reference column of the first bayonet connector 1 111 is aimed to installing hole 31 and be mounted to circuit board 3, due to the fixing relation between reference column 111 and installing hole 31, at first the position of the first bayonet connector 1 is determined.Secondly, allow the second bayonet connector 2 near the first bayonet connector 1, and the second bayonet connector 2 is fit in the receiving space 112 between the protuberance 110 of the first bayonet connector 1 and is positioned on circuit board, at this moment, the protuberance 110 of the first bayonet connector 1 is contained in the depressed part 210 of the second bayonet connector 2, thereby allow the first bayonet connector 1 and the second bayonet connector 2 be interlocked, this will shorten the distance between the first bayonet connector 1 and the second bayonet connector 2 greatly, thereby reduce the space that this takies on circuit board card edge connector combination.In addition, the protuberance 110 of the first bayonet connector 1 can prevent that the second bayonet connector 2 is to two lateral movements, thereby realizes locating effect preferably.
The protuberance 110 of the present invention's the first bayonet connector 1 and the depressed part 210 of the second bayonet connector 2 can provide guiding and positioning action when installing on circuit board at card edge connector combination, therefore also can be called as the cooperation installation portion.In addition, the localization method of card edge connector combination of the present invention is simple and convenient, is conducive to simple flow.
