[embodiment]
As depicted in figs. 1 and 2, the combination of this creation bayonet connector comprises first bayonet connector 10 and second bayonet connector 20 that is installed on circuit board 200, wherein second bayonet connector 20 is positioned at the forward position, below of first bayonet connector 10, and electronic cards module 300 is respectively so that from up to down mode and bottom-up mode are mounted in first bayonet connector 10 and second bayonet connector 20.
As shown in Figure 3 and Figure 4, first bayonet connector 10 is the lengthwise shape, the support arm 12 that it comprises OBL insulating body 11 and extend forward straight at the body 11 relative two ends of insulating certainly.Insulating body 11 comprises upper wall 111 and the lower wall 112 that is oppositely arranged, and is respectively equipped with the terminal conduit in upper wall 111 and the lower wall 112 accommodating conducting terminal 13, and is provided with slot 113 between upper wall 111 and the lower wall 112 to accommodate electronic cards module 300.Thereby slot 113 forms a knob of key 114 on the vertical direction of a close wherein support arm 12 is divided into the different two parts of length with slot 113, the breach (not shown) that electronic cards module 300 front ends form must with knob of key 114 corresponding could insertions in the slot 113, so knob of key 114 can play the effect of anti-mis-insertion.Support arm 12 is closing on brace table 122 that lower wall 112 places form a level to provide a supporting role when electronic cards module 300 is installed, in addition, support arm 12 closes on the end and also is formed with the holding part 121 of the shape of falling L so that the card effect of detaining to be provided.Wherein, the front end face of upper wall 111 is positioned at the rear of the front end face of lower wall 112, and therefore, the slot 113 between upper wall 111 and lower wall 112 forms the insertion space that is tilted to.
As shown in Figure 5 and Figure 6, the conducting terminal 13 in first bayonet connector 10 comprises upper terminal 132 and the lower terminal 131 that is contained in respectively in upper wall 111 and the lower wall 112.Upper and lower terminal 132,131 is respectively equipped with contact site 1321,1311 that protrudes in the slot 113 and the weld part 1322,1312 that extends downwards.The contact site 1321 of upper terminal 132 is positioned at the rear of the contact site 1311 of lower terminal 131, that is to say the inboard of the contact site 1321 more close slots 113 of upper terminal 132, contact with the contact site 1311 of lower terminal 131 earlier when therefore electronic cards module 300 inserts, move down along with electronic cards module 300 then and contact with the contact site 1321 of upper terminal 132.Therefore electronic cards module 300 is mounted in first bayonet connector 10 in top-down mode.In addition, weld part 1322,1312 is surface soldered type leg, and weld part 1322,1312 is welded in first solder side 130 of the upper surface that is positioned at circuit board 200.
Conducting terminal 23 in second bayonet connector 20 comprises last conducting terminal 232 and the following conducting terminal 231 that is contained in respectively in upper wall 211 and the lower wall 212.Upper and lower conducting terminal 232,231 is respectively equipped with contact site 2321,2311 that protrudes in the slot 213 and the weld part 2322,2312 that extends downwards.The contact site 2321 of last conducting terminal 232 is positioned at the place ahead of the contact site 2311 of conducting terminal 231 down, that is to say down the inboard of the contact site 2311 more close slots 213 of conducting terminal 231.Contact with the contact site 2321 of last conducting terminal 232 earlier when therefore electronic cards module 300 inserts, move down along with electronic cards module 300 then and contact with the contact site 2311 of following conducting terminal 231.Therefore electronic cards module 300 is mounted in second bayonet connector 20 in from bottom to top mode, and can not interfere with first bayonet connector 10, and this is convenient to consumer's operation.In addition, weld part 2322,2312 is stitch type leg and 215 extends upward from the resettlement section, and weld part 2322,2312 is connected in second solder side 230 of the upper surface that is positioned at circuit board 200.That is to say, first solder side 130 and second solder side 230 are positioned at the same side of circuit board and are in same plane,, only need weld in a side of circuit board 200 and get final product when circuit board 200 is installed at first bayonet connector 10 and second bayonet connector 20, this will simplify installation process.Since first bayonet connector 10 different with second bayonet connector, 20 structures and be before and after arrangement, the distance between the contact site 2321 of the contact site 1321 of the upper terminal 132 of first bayonet connector 10 and the upper terminal 232 of second bayonet connector 20 is greater than the distance between the contact site 2311 of the lower terminal 231 of the contact site 1311 of the lower terminal 131 of first bayonet connector 10 and second bayonet connector.
After first bayonet connector 10 and second bayonet connector 20 are mounted to circuit board 200, the resettlement section 215 and the lower wall 212 of second bayonet connector 20 is positioned at the below of circuit board 200, and upper wall 211 is positioned at the place ahead of first bayonet connector 10, in addition, the location division 222 of support arm 22 both sides is fixed on the circuit board 200.Being provided with like this can effectively reduce the whole height of stack cards edge connector, thereby helps the miniaturization development of electronic product.In addition, insertion space (promptly two bearing of trends that insert spaces are different) under first bayonet connector 10 and second bayonet connector 20 are respectively equipped with the insertion space that is tilted to and are tilted to, electronic cards module 300 just can insert in the corresponding slot with different directions respectively like this, and can not interfere phenomenon.This creation also can be adopted other execution modes, and this place will repeat no more.
