Shown in Fig. 2,3,5 and 6, when the lower end of housing 31 is connected in crust component 11 peripheral, the rear surface that inserts projection 32, wide projection 33 and narrow projection 34 is projected into the lower surface below of crust component 11 downwards a little, and this situation with the lower surface of portion 22 is identical.This permission insertion projection 32, wide projection 33 and narrow projection 34 low temperature are soldered to and are formed on the substrate 51 lip-deep corresponding pads.At least some pads are connected in the relevant ground traces (groundtraces) on the substrate 51.Therefore, housing 31 is a ground connection, thereby it can play electromagnetic shielding.
All pads that link to each other with narrow projection 34 all are connected in the relevant ground traces on the substrate 51.As shown in Figure 7, narrow projection 34 preferably is positioned near the tip of portion 22 of terminal 21, and planar is arranged to serve as the summit of the isosceles triangle that the tip of narrow projection 34 and portion 22 forms.In other words, cuing open in the cutaway view of getting along Fig. 2 line C-C, narrow projection 34 preferably is positioned near the tip of portion 22 of terminal 21, and be arranged to, set up identical distance between the tip of each narrow projection 34 and two portion 22, the tip of portion 22 is with the isosceles triangle shown in narrow projection 34 forms.
Shown in Fig. 5-7, the lower end of housing 31 is connected in the situation of periphery of crust component 11 therein, inserts projection 33 and is inserted among the corresponding insertion through hole 12b.In this case, the side surface 13a of the best butt end projection pieces 13 of the inner surface of wide projection 33, but this is not enforceable.The best butt of end surfaces 14a of the end surfaces 13b of end projection pieces 13 and intermediate projection pieces 14 is corresponding to the inner surface of the end portion of the housing 31 of the short side of housing 31, but this is not enforceable.In addition, insert the inner surface of the relative housings support part 12 of outer surface butt of projection 32, near the part of housing 31 lower ends the insertion projection 32 is packed among the groove-like clearance 12a.Therefore, housing 31 and crust component 11 link together reliably, and housing 31 is kept reliably by crust component 11.Thereby, can keep socket shape firmly, consistently.
The main body of housing 31 preferably includes thick wall part 31a and thin-walled portion 31b.In this case, consider the intensity of housing 31, thin-walled portion 31b preferably extends (rangeover) preset distance from the upper end of housing 31.Reference marker 31c represents the line of demarcation between thick wall part 31a and the thin-walled portion 31b.The upper part of housing 31 is in sweep 36a bending, thereby forms outward-dipping sloping portion 36.Sloping portion 36 is included among the thin-walled portion 31b.Sloping portion 36 is funneling upwards, thereby is convenient to module 53 is inserted into the housing 31 from the top.In thin-walled portion 31b, notch portion 35 is formed on the position corresponding to sweep 35a.Therefore, thin-walled portion 31b is divided into four independent sectors on four planes that are equivalent to housing 31.
As shown in figs. 1 and 6, vertically the engagement slot 47 of the length of extending is formed in the plane of housing 31, and housing 31 has the projection 32 of insertion, but does not have coupling part 37.For the direction of indicating module 53, i.e. the polarity of module 53, a polar bond is formed on the sidewall of module 53 with outwards outstanding state.When installed module 53, module 53 is inserted into the housing 31 from the top, polar bond is packed in the engagement slot 47.Like this, module 53 is installed in the socket 10 with predetermined direction, is exposed to the linking arm part 23 that predetermined pads on the basal surface of module 53 is connected in respective terminal 21.
Bridging part 48 is integrally formed with sloping portion 36, so that projects upwards from the upper end of sloping portion 36, and extends along the upper end of engagement slot 47.Bridging part 48 connects the part of the sloping portion 36 on the relative both sides that are positioned at engagement slot 47 integratedly, thereby strengthens the intensity on housing 31 planes that form engagement slot 47, and prevents this plane deformation.As illustrated in fig. 1 and 2, bridging part 48 is further crooked from sloping portion 36, with the level substantially that becomes.Therefore, as shown in figs. 1 and 4, the upper part upward opening of engagement slot 47, like this, when installed module 53, the polar bond of module 53 can easily insert the engagement slot 47 from the top.
Two first ground spring sheets 41 that serve as elastic contact chip are formed on each plane in two planes that form the housing 31 that inserts projection 32.The metal coating that forms on the sidewall surfaces 55 of the module 53 that 41 contacts of the first ground spring sheet are installed in socket 10, thus be electrically connected on the metal coating.The metal coating of module 53 plays electromagnetic shielding.By contacting the first ground spring sheet 41, the metal coating of module 53 is electrically connected on the ground trace on the substrate 51 via housing 31.Can according to circumstances select the number and the position of the first ground spring sheet 41.Because the first ground spring sheet 41 is by forming by means of for example die-cut housing 31 that partly cuts, opening 42 is formed on around the corresponding first ground spring sheet 41.
Two second ground spring sheets 43 that serve as elastic contact chip are formed on each plane in two planes that do not form the housing 31 that inserts projection 32.The metal coating that forms on the sidewall surfaces 55 of the module 53 that 43 contacts of the second ground spring sheet are installed in socket 10, thus be electrically connected on the metal coating.The formation of the second ground spring sheet 43 and function class are similar to the first ground spring sheet 41.Can according to circumstances select the number and the position of the second ground spring sheet 43.In the present embodiment, the second ground spring sheet 43 is formed adjacent to each other.Therefore, an opening 44 is individually formed around two second ground spring sheets 43.
Two locking spring leafs 45 that serve as elastic contact chip are formed on each plane in two planes that do not form the housing 31 that inserts projection 32.Locking spring leaf 45 is bonded in the re-spective engagement recess 57 (this will be described below) that forms on the sidewall surfaces 55 of the module 53 of installing in the socket 10, thus locking module 53.The same with the situation of the second ground spring sheet 43 as the first ground spring sheet 41, owing to lock spring leaf 45 by forming by means of for example die-cut housing 31 that partly cuts, opening 46 is formed on around the corresponding locking spring leaf 45.The metal coating of module 53 also is formed on and engages in the recess 57 lip-deep situations therein, and locking spring leaf 45 also plays the ground spring sheet as the first and second ground spring sheets 41 and 43.
Below with reference to Fig. 8-16 in detail, the structure of housing 31 will be described.
Fig. 8 is the perspective view of the housing 31 observed from the top along the relative direction of Fig. 1.In Fig. 8, can be clear that the upper part of engagement slot 47 and the shape of bridging part 48.Can be clear that following situation in Fig. 9,12,13 and 16: bridging part 48 is further crooked from sloping portion 36, with the level substantially that becomes; And the upper part upward opening of engagement slot 47.In Fig. 8, can be clear that the shape and the convex part 37a of coupling part 37.Can be clear that following situation in Figure 10 and 15: coupling part 37 is in the upper end of sloping portion 36 and insert between the lower end of projection 32 and extend vertically.
The first ground spring sheet 41, the second ground spring sheet 43 and locking spring leaf 45 are inwardly outstanding from the side wall inner surfaces of housing 31.Shown in Figure 13-15, the first ground spring sheet 41, the second ground spring sheet 43 and locking spring leaf 45 present a kind of form of long narrow rectangular elements, this rectangular elements has the upper end of the thin-walled portion 31b that is connected in housing 31 integratedly, this rectangular elements dips down and tiltedly extends, and is freely in its lower end.Shown in Figure 11 and 12, the end portion of the first ground spring sheet 41, the second ground spring sheet 43 and locking spring leaf 45 is outwardly-bent, makes the biggest ground of sweep inwardly outstanding.Therefore, in the process of installed module 53, the sidewall surfaces 55 of the sweep butt module 53 of the first ground spring sheet 41, the second ground spring sheet 43 and locking spring leaf 45, make module 53 sidewall surfaces 55 with the contacted while of sweep, can move smoothly.
As shown in figure 11, the end portion of each locking spring leaf 45 is crooked widely, and with the level substantially that becomes, the curved portions angle is an acute angle.Therefore, the sweep of locking spring leaf 45 is adapted at the joint recess 57 that forms on the sidewall surfaces 55 of module 53, and like this, sweep engages with engaging recess 57 regularly, in case engage, just is difficult to break away from.Shown in Figure 11,12 and 16, the sweep of locking spring leaf 45 is inwardly more outstanding more than the sweep of the first ground spring sheet 41 and the second ground spring sheet 43.This be because, the sweep of the first ground spring sheet 41 and the second ground spring sheet 43 touches the sidewall surfaces 55 of the module 53 that is installed in the socket 10, and the sweep of locking spring leaf 45 engages with the corresponding joint recess 57 that forms on the sidewall surfaces 55 of module 53.
Below with reference to Figure 17-19, will the spring function of the first ground spring sheet 41, the second ground spring sheet 43 and locking spring leaf 45 be described.In the process of installed module 53, outwards be pressed to by the sidewall surfaces 55 of module 53 for the sweep of each locking spring leaf 45 of free end portion near the position the inner wall surface of housing 31.Subsequently, when finishing the installation of module 53, the sweep of locking spring leaf 45 must enter the joint recess 57 of module 53.Therefore, the sweep long distance of must moving away in whole range of movement, must be born towards the sidewall surfaces 55 of module 53 or engages the power that recess 57 compresses sweep.In other words, locking spring leaf 45 all must play the effect of spring in the whole range of movement of sweep.
In order to satisfy above-mentioned requirements, locking spring leaf 45 and opening 46 present shape and size shown in Figure 17.Each opening 46 comprises a wide part 46a who extends laterally, and this wide part 46a is positioned at the zone of the thin-walled portion 31b of the outstanding housing 31 of locking spring leaf 45.In Figure 17, L1 represents the distance from the free end of locking spring leaf 45 to the boundary member locking spring leaf 45 and the thin-walled portion 31b; That is the length of locking spring leaf 45; L2 represents that leniently part 46a is to the distance of the upper end of sloping portion 36; W1 represents to lock the width of spring leaf 45; And W2 represents the distance between the opposite end of wide part 46a.
L1 preferably is provided with longlyer, so that make locking spring leaf 45 play spring; In other words, so that realize following situation: in the time of the moving range of the sweep that obtains locking spring leaf 45, locking spring leaf 45 bears towards the sidewall surfaces 55 of module 53 or engages the power that recess 57 compresses sweep, can not cause the permanent deformation of locking spring leaf 45.But, because, concerning L1, be difficult to long enough to the restriction of the position of the joint recess 57 of the vertical dimension of for example housing 36 and module 53.Thereby, in the present embodiment, make W2 greatly to maximum as far as possible degree, make L2 little to minimum as far as possible degree.By this process, in Figure 18, shadow region 45a presents long, narrow rectangular shape, and it plays the effect of torque spring.That is to say that regional 45a stands the elastic distortion distortion.Especially, in the present embodiment, because regional 45a is seated on the thin-walled portion 31b, even in a little less than the power that puts on this zone 45a from locking spring leaf 45, this zone 45a also stands torsional deformation; That is, play the effect of torque spring.Therefore, locking spring leaf 45 plays the effect of spring; In other words, in the time of the moving range of the sweep that obtains locking spring leaf 45, locking spring leaf 45 bears towards the sidewall surfaces 55 of module 53 or engages the power that recess 57 compresses sweep, can not cause the permanent deformation of locking spring leaf 45.Can set size L2, W1 and W2 arbitrarily, make regional 45a play torque spring.
Simultaneously, in the process of installed module 53,, do not need long moving range to being the sweep of the first ground spring sheet 41 of free end portion and the second ground spring sheet 43.Therefore, compare with locking spring leaf 45, concerning the sweep of the first ground spring sheet 41 relevant with the spring action that plays the first and second ground spring sheets 41 and 43 and the second ground spring sheet 43, moving range can be shorter, like this, the zone that has not needed the torque spring effect.Thereby as shown in figure 19, the upper end of the region distance sloping portion 36 of the thin-walled portion 31b of the housing 31 that each first ground spring sheet 41 is given prominence to is far away.Just lock spring leaf 45, wide part 46a is arranged on opening 46 places separately.Equally, with regard to the first ground spring sheet 41, wide part 42a also can be arranged on opening 42 places separately.This equally also is applicable to the second ground spring sheet 43.
Shown in Figure 20 and 21, socket 10 is installed on the substrate 51 in advance.Substrate 51 has the cloth line tracking.The cloth line tracking is exposed on the surface of substrate 51 in the zone of mounting receptacle 10 at least, thereby forms coupling part, for example lug plate (lands) and pad.The terminal 21 of socket 10 can be connected on this coupling part by means of for example eutectic welding.Specifically, the lower surface of the portion 22 of terminal 21 is connected on the corresponding coupling part by means of for example eutectic welding.Substrate 51 also has ground trace.Ground trace is exposed on the surface of substrate 51 in the zone of mounting receptacle 10 at least, thereby forms coupling part, for example lug plate and pad.The insertion projection 32 of socket 10, wide projection 33 and narrow projection 34 can be connected on the coupling part by means of for example eutectic welding.Specifically, the rear surface of insertion projection 32, wide projection 33 and narrow projection 34 is connected on the coupling part by means of for example eutectic welding.
In the state before installed module 53, the free end of the linking arm part 23 of terminal 21 projects upwards the top of crust component 11 upper surfaces widely.The sweep of the first ground spring sheet 41, the second ground spring sheet 43 and locking spring leaf 45 is inwardly outstanding widely from the inner wall surface of housing 31.If t1 represents the thickness of the thick wall part 31a of housing 31, when t2 represented the thickness of thin-walled portion 31b, then t1 and t2 presented the relation of " t1＞t2 ".
Then, module 53 is inserted into the housing 31 from the top, thereby is installed in the socket 10 shown in Figure 22 and 23.Module 53 has top surface 54, sidewall surfaces 55 and basal surface 56.On top surface 54 and sidewall surfaces 55, be formed with metal coating by for example electroplating.Predetermined pads is exposed on the basal surface of module 53, and is connected in the linking arm part 23 of respective terminal 21.Because sloping portion 36 is formed on the upper end of housing 31 so that the funneling that makes progress, module 53 can easily be inserted into the housing 31 from the top.One polar bond (not shown) is formed on outwards outstanding state on the plane of sidewall surfaces 55 of module 53.When installed module 53, module 53 is inserted into the housing 31 from the top, pack in the engagement slot 47 of housing 31 to cause polar bond.Because the upper part upward opening of engagement slot 47, the polar bond of module 53 can easily be inserted into the engagement slot 47 from the top.Therefore, module 53 is installed in the socket 10 with predetermined direction, is exposed to the linking arm part 23 that predetermined pads on the basal surface 56 of module 53 is connected in respective terminal 21.
