As mentioned above, needle stand sheet 160,162 is can be by the interaction (for example passing through snap fit) of flank and passage locked or remain in the procapsid 130.Particularly, referring to Fig. 9, the size of the first locking flank 220 is provided with like this, and in the time of in it inserts first passage groove 250 fully, rearmost hook 236 will pass shoulder 264 on the flank, and this shoulder 264 forms by the channel slot setting being passed first engaging arms 142.Similarly, in Figure 10, the size of the second locking flank 222 is provided with like this, makes the hook 246 on it will pass second shoulder 274 in assembling.Locking flank 220,222 can upwards buckle in the part of passage 250,252, and wherein these passages are set to pass completely through second engaging arms 142.Be appreciated that the first needle stand sheet 160 or the second needle stand sheet 162 with respect to procapsid 130 motion backward in, shoulder 264,274 and stop surface 236,246 mutually against, prevent that thus needle stand sheet and housing are separated from each other.In Fig. 9 and embodiment shown in Figure 10, first aims at flank 238 and second aims at flank 248 and can have similar structure with alignment slot, thereby helps the following mounting edge 182 of needle stand sheet 160,162 is remained on the housing 130.Return Fig. 2, because the first locking flank 220 and the interlaced arrangement of second locking between the flank 222, the locking flank is housed in the passage 250,252 will have formed the profile that is similar to braiding along the outer surface of first engaging arms 142.
Because therefore locking flank and passage have avoided the mistake pairing of the first and second needle stand sheets.As mentioned above, an advantage of this design is that the first needle stand sheet 160 and the second needle stand sheet 162 can be arranged to the mode differential signal transmission to cooperatively interact, thereby needs the terminal feature different mutually.For example, referring to Figure 11, the terminal that holds in the first needle stand sheet 160 and the second needle stand sheet 162 can be grouped into signal terminal 280 or earth terminal 290, signal terminal 280 is used for conducting electrical signals, earth terminal 290 is used to provide electrical ground or shielding, to prevent the interference between the adjacent signal terminal and to crosstalk.Can have first width 282 at butt joint contact site 170 and the pars intermedia of complying with between the terminal 172 signal terminal 280 that extends, and the pars intermedia of earth terminal 290 can have second width 292.Although the width 282 of each signal terminal 280 in the same needle stand sheet and the width 292 of each earth terminal 290 change between terminal and terminal slightly, but in the present embodiment, they preferably should be maintained in such scope, make that promptly the width of each earth terminal approximately is the twice of a pair of adjacent signal terminal.The cross section of signal terminal 280 and earth terminal 290 can be square or rectangle.
In order to conduct differential signal by needle stand sheet 160,162, signal terminal 280 is arranged to adjacent differential pair 284 in each needle stand sheet.But differential pair can conduct by applying the differential signal that two equal and opposite in directions opposite polarity complementary voltage produce to this each right terminal.The receiving system of reception differential signal can read the difference between these two right terminals.Earth terminal 290 separates another differential pair in each differential pair 284 and the same needle stand sheet.Personnel as the differential signal technical field are known, and the signal terminal 280 in the differential pair 284 will tend to intercouple, and avoid interference other signal terminal in the needle stand sheet, thereby reduce the distortion of transmission data.This is known as edge coupling sometimes because be coupling in together terminal along the narrower side of their rectangular cross section mutually in the face of or relatively.
For fear of the interference between the differential pair of the first needle stand sheet 160 and the second needle stand sheet 162, between the first and second needle stand sheets, in the needle stand sheet, provide the differential pair 286 of terminal row and the interleaved order of earth terminal 290 to put upside down.For example, in the first needle stand sheet 160, when looking along abutting edge 184, two terminals near the top edge 186 of the top form differential pairs 284, and it is represented with Reference numeral 300.The differential pair 300 of contiguous the top be earth terminal, it is represented with Reference numeral 302.Correspondingly, the grouping of terminal is staggered along abutting edge 184, to comprise second differential pair 304, the second earth terminals, 306, the three differential pairs 308 and near the 3rd earth terminal 310 of mounting edge 182.On the contrary,, in the second needle stand sheet 162, has the earth terminal of representing with reference marker 320, as near the terminal of the top of top edge 186 when when abutting edge 184 is looked.Along abutting edge 184 ensuing orders are differential pair 322, the second earth terminal 324, the second differential pairs, 326, the three earth terminals 328 and near the 3rd differential pair 330 of mounting edge.
Because reversed order, when the first needle stand sheet 160 and the second needle stand sheet 162 are disposed adjacent one another, the differential signal in the first needle stand sheet will be relative with the earth terminal 320,324 and 328 in the second needle stand sheet to 300,304 and 308.Similarly, the earth terminal 302,306 in the first needle stand sheet 160 will be relative to 322,326 and 330 with the differential signal in the second needle stand sheet 162 with 310.Like this, the differential pair in each needle stand sheet separates and isolates with differential pair in the adjacent needle stand sheet by relative earth terminal, crosstalks and disturbs with further minimizing.This is known as broadside coupled because terminal is wide along them or the side of broad mutually in the face of or relatively.For fear of when the needle stand sheet is adjacent mutual physics contact of relative terminal and short circuit in the first and second needle stand sheets when arranging, the insulative support frame 180 of first portion can comprise one or more thin plastic stents 196, this support 196 partly the cross terminal pars intermedia and extend keep to separate.Although each needle stand sheet is described to have three differential pairs and three earth terminals that are associated, should be appreciated that these numbers can be different with being provided with in other embodiments.
Use Lock Part and holding member that another advantage of contiguous housing aligning of the first and second needle stand sheets and maintenance is that the needle stand sheet can be designed to simplify assembling.Be shown as referring to Fig. 8 and 11, the first needle stand sheets 160 and the second needle stand sheet 162 and be spaced from each other.Because the smooth rectangular shape of insulative support frame 180, the first needle stand sheet can have two opposed major surfaces or side as can be seen, comprises lateral surface 340 and parallel side or the medial surface 342 of contacting.The second needle stand sheet 162 comprises second lateral surface 344 and the second parallel medial surface 348 equally.When the first needle stand sheet 160 and the second needle stand sheet, 162 adjacent layouts when forming needle stand, first medial surface 342 and second medial surface 348 are in contact with one another.In order to make the first needle stand sheet 160 and the second needle stand sheet 162 can slide relative, first medial surface 342 preferably be made into level and smooth and relatively flat, and it does not have can hinder any protruded stigma or the projection protruded from support frame 180 of sliding.Second medial surface 348 also is a relatively flat, can not hinder the protruded stigma or the projection of the sliding contact between the needle stand sheet.
Return Fig. 2 and Fig. 3, will explain a kind of mode below 110 assemblings of subcard connector.With the second needle stand sheet, 162 placed adjacent before, the first needle stand sheet 160 can be aimed at and be inserted in the corresponding first needle stand film traps of arranging in the procapsid 130 200.The first locking flank and first passage can engage, thereby the first needle stand sheet 160 and housing 130 are locked mutually.Be close to the mounted first needle stand sheet, another first needle stand sheet can be aimed at and be locked in another first passage.Continue this process, be loaded in the procapsid up to the first all needle stand sheets, thereby fill up all first passages.The second needle stand sheet can be aimed at second channel and insert wherein.As can be seen, the spacing between any two first needle stand sheets of installing can and the lateral surface and the thickness between the medial surface of the second needle stand sheet roughly the same.Because the first and second needle stand sheet sliding contacts mutually, the second needle stand sheet can slide by the corresponding relatively first needle stand sheet, thereby the second needle stand sheet is housed in the second needle stand film trap, and second locks the merging interlocking of joining of flank and second channel groove.Be inserted through the isolated first needle stand sheet in order to allow the second needle stand sheet to slide better, the edge of insulative support frame and bight can have chamfering.In the time of in the needle stand sheet inserts housing 130 fully, the shoulder 187 of needle stand sheet will in the face of and preferably in abutting connection with the edge or the surface 254 of housing sidewall 142,144, thereby the groove of 210,212 engage 130 of the flank on it.If being aligned in of the first needle stand sheet 160 in the housing inserted before the second needle stand sheet 162 or among must align, straightening tool can engagement grooves 194 come mobile needle stand so.
By the first needle stand sheet is installed the mode of the second needle stand sheet in the procapsid is installed then in the procapsid, as shown in Figure 1, can assembles adjacent needle stand 150 whole needle stand group 152 stacked side by side.The advantage of this method is, need not in advance needle stand half one be assembled into needle stand.In addition, because needle stand does not need the pillar and the butt hole that are used for assembling in advance, the foozle of the size of these parts can not influence the structure of electric connector, and has saved labour cost.
