Secondly, be described in detail in holding section that forms on the shell and the notch part that on cover body, forms with reference to Fig. 3.The figure of its middle process when Fig. 3 is embedded into shell for expression with cover body.In addition, for convenience of explanation, only the side wall portion to a side describes.
As shown in Figure 3, holding section 32 has protuberance 48 and restrictions 49 and its cross section forms T word shape, and to one side-prominent, this restrictions 49 broadens from the thickness direction of the outside shell 2 in outstanding end of protuberance 48 this protuberance 48 from the lateral surface 51 of side wall portion 5.And it is back-to-back with the gathering sill 31 that forms on the medial surface of side wall portion 5 that holding section 32 is set.Therefore, compare with the structure that gathering sill 31 separates with short transverse, can make the thickness attenuation of shell 2, thereby can realize the slimming of card connector 1 with holding section 32.(with reference to Fig. 4 (a)).
The outstanding length of protuberance 48 has, allow the side plate 36 of cover body 3 invade side wall portions 5 lateral surface 51 and and these lateral surface 51 opposed restrictions 49 between length.The upper surface 53a of protuberance 48 and the height dimension between the lower surface 53b have, with the roughly the same length of gap width of the notch part 45 that forms on side plate 36.Therefore, side plate 36 as spigot surface, invades the upper surface 53a of protuberance 48 and lower surface 53b in gap 54a, the 54b between restriction face 52a, the 52b of the lateral surface 51 of side wall portion 5 and restrictions 49.
As mentioned above, by inserting protuberance 48 in the notch part 45 and the front of side plate 36 invaded in gap 54a, the 54b, holding section 32 engaging shell 2 and cover bodies 3.In this case, card connector 1 is designed to, and embeds shell 2, the front of engaging holding section 32 and side plate 36 from the rear by making cover body 3.Therefore, the engaging of holding section 32 and side plate 36 front does not need aligned position.And, by the engaging between holding section 32 and side plate 36 front, cause the distortion of shell 2 when suppressing welding card connector 1 because of reflux heat.In addition, that the leeway of handicapped degree takes place is impassable yet because of the distortion of shell 2 to make the size of gap 54a, 54b have card connector 1.
And, be set in the above-described embodiment, at notch part 45, make and the opposed opposed faces 55a of short transverse, 55b between gap width and the height dimension of the upper surface 53a of protuberance 48 and lower surface 53b roughly the same, but also can be set at, the outstanding compacting rib that forms on the lower surface 53b of protuberance 48, before assembling than the gap width tight (harshness) of notch part 45 a bit.Under above-mentioned situation, make the distortion of compacting rib by in notch part 45, inserting protuberance 48, thereby can suppress the loosening of above-below direction.
Below, the distortion prevention structure of shell is described with reference to Fig. 4.Fig. 4 prevents the key diagram of structure for casing deformation.
Fig. 4 (a) expression card connector 1 does not have soldered initial condition.In this case, the protuberance 48 of holding section 32 is inserted in the notch part 45 of side plate 36, and the front of side plate 36 is got involved in gap 54a, the 54b.When welding card connector under this initial condition, by the distortion of the next side wall portion 5 in the engaging limit return flow torrid zone of protuberance 48 and side plate 36 front.
For example, shown in Fig. 4 (b), when side wall portion 5 when inserting the inside bend that the space narrows down, restriction face 52a, the 52b of restrictions 49 are connected to the outer surface 56 of side plate 36, thus restriction side wall portion 5 is out of shape to the inside.On the other hand, when side wall portion 5 when inserting the outside curve that the space broadens, the lateral surface 51 of side wall portion 5 is connected to the inner face 57 of side plate 36, thus restriction side wall portion 5 is out of shape laterally.
And, shown in Fig. 4 (c), when side wall portion 5 when downside twists, the upper side abuts of side wall portion 5 lateral surfaces 51 is in the upside of side plate 36 inner faces 57, the restriction face 52b of restrictions 49 downsides is connected to the downside of side plate 36 outer surfaces 56, thus 5 distortion of restriction side wall portion.On the other hand, when side wall portion 5 when upside twists, the restriction face 52a of restrictions 49 upsides is connected to the upside of side plate 36 outer surfaces 56, the downside of side wall portion 5 lateral surfaces 51 is connected to the downside of side plate 36 inner faces 57, thereby the distortion of restriction side wall portion 5.
Also have, shown in Fig. 4 (d), when side wall portion 5 was bent downwardly, the lower surface 53b of protuberance 48 was connected to the downside opposed faces 55b of notch part 45, thereby restriction side wall portion 5 is out of shape downwards.On the other hand, when side wall portion 5 was bent upwards, the upper surface 53a of protuberance 48 was connected to the upside opposed faces 55a of notch part 45, thus upwards distortion of restriction side wall portion 5.
As mentioned above, by the engaging between holding section 32 and side plate 36 front, restriction side wall portion 5 is left and right directions and direction of twist distortion up and down.Especially, because restriction side wall portion 5 is crooked to the inside, thus the space of inserting card 61 is narrowed down, thus can not hinder the insertion of 61 pairs of card connectors 1 of card and extract.And, because restriction side wall portion 5 downward lateral bending songs, so prevented from the welding of cover body 3 not to be hindered because the depression of side wall portion 5 front makes cover body 3 float from substrate 59.
The assembling operation of card connector is described with reference to Fig. 5.Fig. 5 is the key diagram of card connector assembling operation.In addition, in Fig. 5, (a), (c) overlook key diagram for the card connector assembling operation, (b), (d) be the side-looking key diagram of card connector assembling operation.
At first, shown in Fig. 5 (a) and (b), shell 2 is carried out the position alignment of upper plate portion 34, side plate 36 and the lower board unit 37 of cover body 3.Specifically, aiming at upper plate portion 34 on the upper surface of shell 2, aiming at side plate 36 on the lateral surface of shell 2, on the lower surface of shell 2, aiming at lower board unit 37 respectively.Then, embed cover body 3 from the rear of shell 2, and upper plate portion 34, side plate 36 and lower board unit 37 are used as guiding cover body 3 is slided on shell 2.At this moment, cover body 3 slides with the state to shell 2 location.
Secondly, when cover body 3 was embedded in the front of shell 2, the front of cover body 3 and holding section 32 began engaging.At this moment, shown in Fig. 5 (c), (d), the front of cover body 3 is used as the upper surface 53a of restriction face 52a, the 52b of restrictions 49, protuberance 48 and lower surface 53b as gap between restriction face 52a, the 52b that guiding invades the lateral surface 51 of side wall portion 5 and restrictions 49.And when the front of cover body 3 invaded gap 54a, 54b, protuberance 48 was used as opposed faces 55a, the 55b of notch part 45 as guiding and is inserted in the notch part 45.
Then, in the time of in cover body 3 embeds shell 2 fully, the anti-shedding part 46 of cover body 3 rear end side is connected to the abutting part 44 of shell 2, and card connector 1 is assembled.In this case, holding section 32 and notch part 45 are designed to make position alignment by cover body 3 is embedded shell 2.Therefore, when being assembled into cover body 3 on the shell 2, just there is no need to aim at the position of holding section 32 and notch part 45, thereby can improve the packaging efficiency of card connector 1.
