Moreover, in recent years, with the small size of cards, card connectors have been required to be miniaturized. Although the card material suitable for the above-mentioned small-sized card is attached to the circuit board by the (four) connection (four), there is a problem that the outer casing is easily deformed by the reflow heat. Conventionally, as a card connector for a small card, a card connector capable of suppressing deformation of the casing due to reflow heat has been known (for example, refer to Patent Document 1). By the locking piece extending from the metal cover to the lower side, the locking hole formed in the upper surface of the resin case is stopped, and the card and the card are connected. The outer casing is formed in a shape of a 17-shaped shape in which the side wall portion extends forward from the inner wall portion of the plurality of terminals in a plan view, and a card insertion space is formed between the pair of side wall portions. Further, a plurality of restricting pieces that restrict deformation of the pair of side wall portions are provided on the cover body at the position of the front end side of the side wall portion. The card connector restricts the front end side of a pair of side wall portions which are easily affected by the reflow heat by the restricting piece formed on the cover body, thereby suppressing deformation of the outer casing. According to the above configuration, it is possible to control the pair of side wall portions to be caught in the insertion space side of the card, and it is possible to prevent the insertion and removal of the card from the card connector from being hindered. [Provisional Technical Documents] 151882.doc 201140464 [Patent Document 1] [Patent Document 1] Japanese Patent Laid-Open Publication No. 2003-33 No. 1975 [Draft] [Problems to be Solved by the Invention] However, In the card connector, when the cover body is worn on the outer casing, it is necessary to respectively align the locking piece of the cover body with the locking hole of the outer casing, so that the restricting piece of the cover body is aligned with the one side wall of the outer casing, thereby There is a problem of poor assembly. The present invention has been made in view of the above circumstances, and an object thereof is to provide a card connector which suppresses deformation of a casing due to reflow heat and which is excellent in assemblability. [Technical means for solving the problem] In the present invention, the connector for a card is characterized in that it includes a casing having a side wall portion formed along a direction in which the card is inserted, and a cover body which is self-contained by the outer casing The casing is inserted in the direction in which the card is inserted, and is attached to the casing; and 'the side wall portion is provided with an engaging portion which is embedded by the loading body in a direction along the direction in which the card is inserted.

According to the above configuration, the engagement between the engaging portion provided in the side wall portion and the cover can suppress deformation of the outer casing due to reflow heat when the card filler is welded. In particular, when the outer casing is formed in a U-shaped shape in which the pair of side wall portions extend forward from the inner wall portion in a plan view, it is possible to suppress the deformation of the side wall portion which is easily affected by the reflow heat and by The cover body is fitted into the outer casing from the direction of the insertion direction, and the cover body is engaged with the engaging portion. Since the cover body is mounted on the outer casing, strict alignment is not required because of 151882.doc 201140464. Therefore, it is possible to prevent the outer casing from being changed by the reflow heat and to improve the assembly of the card connector. Further, in the present invention, the card (four) connector is characterized in that the cover body is formed with a notch portion that is cut rearward from the front end along the insertion direction of the card, and the engagement portion has a protruding portion. The outer surface of the side wall portion protrudes outward and is inserted into the notch 胄; and the restricting portion is connected to the protruding end portion of the protruding portion and forms a gap between the outer surface of the side wall portion and the outer surface of the side wall portion. According to the above configuration, the cover body is inserted into the outer casing from the direction along the insertion direction, and the protruding portion is inserted into the notch portion, so that the cover body is formed in the gap between the outer surface of the side wall portion and the regulating portion. The strength of the outer casing can be enhanced by the cover between the outer surface of the side wall portion and the restricting portion, thereby limiting the deformation of the peripheral device due to the heat of reflow. Further, the engaging portion = the engaging portion can be enlarged in the insertion direction, and the strength of the outer casing can be improved without increasing the size of the card connector. In the card connector of the present invention, the card connector is characterized in that the second (four) is expanded toward the distal end side in the middle of the extending direction. According to the above configuration 'when the cover body is thrown into the outer casing from the direction of the insertion direction', it is possible to easily insert the protruding portion from the front end portion of the notch portion. Further, in the invention, the card connector is characterized in that the protruding portion has a notch formed by the insertion of the missing portion and the root portion m11. p inside and deformed ribs. According to the above configuration, the ridge is deformed by inserting the protruding portion into the notch portion rib to suppress the looseness in the vertical direction.

Further, the outer side surface of the side wall portions 5 and 6 of the outer casing 2 is provided with an engaging portion 32 at the front end portion opposite to each of the guide grooves 3. The engaging portion 32 is formed to be engageable with The front end side of the side plate portion 36 of the cover 3 is mainly reinforced by the engagement with the cover 3, and the front end side of the side wall portions 5, 6 is mainly reinforced. The details of the engaging portion 3 2 will be described later. The cover 3 has an upper plate portion 34 that covers the upper surface of the outer casing 2, and an outer peripheral portion 35' that is bent from both end portions of the upper plate portion 34 to cover the outer side surface and the lower surface of the side wall portions 5, 6. The cover body 3 is attached to the outer casing 2 by pushing the upper plate portion 34 and the surrounding portion 35 from the rear along the outer casing 2. That is, the upper plate portion 34 and the surrounding portion 35 are fitted into the outer casing 2 when the cover 3 is fitted On one side of the upper plate portion 34, a pin pressing member 41 for squeezing the stopper pin 22 is formed. The pin pressing member 41 is attached to the lower plate portion 37. The upper cantilever spring is cut down to 151882.doc •10·201140464. The middle portion of the stopper pin 22 is pressed to push the other end of the stopper pin 22 toward the heart-shaped cam groove. At the insertion port 4 side of the upper plate portion 34 The front half portion is formed with a brake piece 42 for preventing the card 6m from coming out. (4) The piece 42 is a cantilever spring which is slightly cut downward, contacts the back surface of the card 61, and controls the card 61 to jump out when it is ejected. The surrounding portion 35 is a side plate portion. 36 and a lower plate portion 37 which covers the outer side surfaces of the side wall portions 5, 6. The lower plate portion 37 forms a bottom wall portion of the card connector i. The side plate portion 36 is formed with a slit from the front end to the rear side. The notch portion 45 is inserted into the outer casing 2 from the rear, and the notch portion 45 is engaged with the engaging portion 32. As described above, the front end sides of the side wall portions 5 and 6 are engaged with the cover body. 3', it is possible to suppress the deformation of the side wall portions 5, 6 which are easily affected by the reflow heat when the connector 1 for soldering the card is welded. The details of the notch portion 45 will be described later. The back side of the side plate portion 36 is formed with a shroud. The body 3 is detached from the outer casing 2 and is prevented from falling off. The cantilever spring extending rearward of the portion 36 is formed by bending the front end portion inwardly. When the cover body 3 is moved in the direction in which the casing 2 is fitted, the fall-preventing portion 46 is deflected outward from the side wall portions 5, 6 to allow The cover 3 is attached to the outer casing 2. After the cover 3 is attached to the outer casing 2, the anti-shedding portion 46 is restored from the outer side to the original position. At this time, the front end of the anti-shedding portion 46 abuts on the side wall portions 5, 6 The abutting portion 44 restricts the cover 3 from moving to the side opposite to the embedding direction. As described above, when the cover 3 is fitted into the outer casing 2, the front end portion and the side wall portions 5, 6 are prevented by the anti-shedding portion 46. The abutment between the abutting portions 44 prevents the cover 3 from coming off the outer casing 2. 1518S2.doc -11 - 201140464 Next, the engaging portion formed in the outer casing and the notched portion formed in the cover body will be described in detail with reference to Fig. 3 . Figure 3 is a view showing the process in which the cover is embedded in the outer casing. In addition, for convenience of explanation, only one side wall portion will be described. As shown in FIG. 3, the engaging portion 32 has a protruding portion 48 and a regulating portion 49, and has a T-shaped cross section. The protruding portion 48 protrudes from the outer side surface 51 of the side wall portion 5 toward one side, and the restricting portion 49 is self-protruding. The protruding end portion of the portion 48 is expanded in the thickness X direction of the outer casing 2, and the engaging portion 32 is disposed to face away from the guide groove 3 formed on the inner side surface of the side wall portion 5. Therefore, the thickness of the outer casing 2 can be made thinner than the configuration in which the engaging portion 32 and the guide groove 31 are separated from each other in the height direction, and the card connector can be made thinner. (Refer to Figure 4(a)). The protruding length of the protruding portion 48 has a length that allows the side plate portion of the cover body 3 to "invade the outer side surface 51 of the side wall portion 5 and the restricting portion 49 opposite to the outer side surface 5". Above the protruding portion 48 The south dimension between the surface 53a and the lower surface has substantially the same length as the notch width of the notch portion 45 formed on the side plate portion 36. Therefore, the side plate portion 36 is the upper surface 53a and the lower surface of the protruding portion 48. As the guide surface, 53b intrudes into the gaps 54a and 5 between the outer side surface 51 of the side wall portion 5 and the regulating surfaces 52a and 52b of the regulating portion 49. The restricting portion 49 has the outer side surface 5 of the side wall portion 5. The opposing restricting surfaces 52a and 52b form the gaps 54a and 54b of the interposing side plate portion 36 between the regulating faces 52a and 52b and the outer side surface 51. The restricting portion 49 is inserted into the gap 54a by the side plate portion. 54b, the deformation of the side wall portion 5 is restricted. When the side plate portion % k is inserted into the gaps 54a, 54b, the restriction faces 52a, 52b of the restriction portion 49 are such that the outer surface of the side portion 151882.doc 201140464 plate portion 36 serves as a guide surface. As described above, the side plate portion 36 is determined by the engaging portion 32, up and down, left and right. In the state of being placed, the gaps 54a and 54b are invaded. Further, the rear end side of the restricting portion 49 is chamfered, and the gap 54a' 54b is extended rearward. The restricting portion 49 allows the front end surface of the side plate portion 36 to easily enter the gap by chamfering. 54a, 541). The notch portion 45 is formed at a substantially intermediate position in the height direction of the side plate portion 36, and extends rearward from the front end portion. The front end portion of the side plate portion 36 is divided into two portions by the notch portion 45 and is interposed. To the gaps 54a, 54b formed above and below the engaging portion 32. Further, in the notch portion 45, the gap width between the opposing faces 55a, 55b in the height direction is as described above, and protruding The heights of the upper surface 53a and the lower surface 53b of the portion 48 are substantially the same. Therefore, the protruding portion 48 of the engaging portion 32 is inserted into the notch portion 45 by using the opposing faces 55a and 55b of the notch portion 45 as guide faces. Further, the front end side of the notch portion 45 is chamfered, and the notch width is expanded forward. The notch portion 45 is chamfered so that the protruding portion 48 of the engaging portion 32 can be easily inserted into the notch portion 45. The hinge 32 is inserted into the protrusion 48 by In the notch portion 45, the front end side of the side plate portion 36 is intruded into the gaps 54a, 54b, and the outer shout 2 is engaged with the cover 3. In this case, the card connector 1 is designed such that the cover body 3 is self-contained The rear portion is fitted into the outer casing 2, and the engaging portion 32 is engaged with the end side of the side plate portion%. Therefore, the engagement between the engaging portion 32 and the front end side of the side plate portion 36 does not require an alignment position. The engagement between the portion 32 and the front end side of the side plate portion 36 can suppress deformation of the outer casing 2 due to reflow heat when the card connector 1 is welded. Further, the size of the gaps 54a, 54b can be made such that the card connector 1 does not become dysfunctional due to the deformation of the casing 2, and the margin is 151882.doc •13-201140464. Further, in the above-described embodiment, the notch portion 45 is set such that the gap width between the opposing faces 55a and 55b facing the height direction is substantially the same as the height dimension of the upper surface 53a and the lower surface 53b of the protruding portion 48. However, it may alternatively be set such that 'the protruding rib on the lower surface 53b of the protruding portion 48' is slightly smaller than the notch width of the notch portion 45 before assembly. In the above case, the pressing rib is deformed by inserting the protruding portion 48 into the notch portion 45, so that the looseness in the vertical direction can be suppressed. The anti-deformation structure of the outer casing will be described below with reference to Fig. 4 . Fig. 4 is an explanatory view of the deformation preventing structure of the outer casing. Fig. 4(a) shows an initial state in which the card connector 丨 is not welded. In this case, the protruding portion 48 of the engaging portion 32 is inserted into the notch portion 45 of the side plate portion 36, and the front end side of the side plate portion 36 is interposed in the gaps 54a, 54b. When the card connector is welded from the initial state, the deformation of the side wall portion 5 due to the heat of reflow is restricted by the engagement of the protruding portion 48 with the front end side of the side plate portion 36. For example, as shown in FIG. 4(b), when the side wall portion 5 is bent toward the inner side where the insertion space is narrowed, the restriction surface 5 of the restriction portion 49; 2a, 52b abuts against the outer surface 56' of the side plate portion 36. The side wall portion 5 is deformed inward. On the other hand, when the side wall portion 5 is bent toward the outer side of the insertion space, the outer side surface 51 of the side wall portion 5 abuts against the inner surface 57 of the side plate portion 36, and the side wall portion 5 is restricted from being deformed outward. Further, as shown in Fig. 4(c), when the side wall portion 5 is twisted to the lower side, the upper side of the outer side surface 51 of the side wall portion 5 abuts against the upper side of the inner surface 57 of the side plate portion 36, and the regulating surface 52b of the lower side of the restricting portion 49. Abutting on the lower side of the outer surface 56 of the side plate portion 36, 151882.doc -14 - 201140464, the deformation of the side wall portion 5 is restricted. On the other hand, when the side wall portion 5 is twisted to the upper side, the regulating surface 52a on the upper side of the regulating portion 49 abuts on the upper side of the outer surface % of the side plate portion 36, and the lower side of the outer side surface 51 of the side wall portion 5 abuts against the side plate portion 36. The lower side of the surface 5 7 limits the deformation of the side wall portion 5. Further, as shown in FIG. 4(d), when the side wall portion 5 is bent downward, the lower surface 53b of the protruding portion 48 abuts against the opposite surface 55b on the lower side of the notch portion 45, thereby restricting the side wall portion 5 downward. Deformation. On the other hand, when the side wall portion 5 is bent upward, the upper surface 53a of the protruding portion 48 abuts against the opposite surface 55 5 a on the upper side of the notch portion 45, thereby restricting the upward deformation of the side wall portion 5. As described above, the deformation of the side wall portion 5 in the up, down, left, and right directions and the twisting direction is restricted by the engagement between the engaging portion 32 and the front end side of the side plate portion 36. In particular, since the bending of the side wall portion 5 toward the inner side is restricted, the space of the insertion card 61 is not narrowed so as not to hinder the insertion and removal of the card-to-card connector 1. Moreover, since the side wall portion Since the bending of the lower side is restricted, the cover 3 is prevented from floating from the substrate 59 due to the depression of the front end side of the side wall portion 5, so that the welding of the cover 3 is not hindered. Hereinafter, the card will be described with reference to FIG. Figure 5 is an explanatory view of the card connector set. In addition, in Fig. 5, (4) is an explanatory view of the card connector assembly, (9) and (4) are card connectors viewed from the side.
