In addition, have the fastening connecting hole 35 that is electrically connected and carries out the fastening of machinery for forming with pressure strip 5 fastenings at metallic plate 3.Fastening connecting hole 35 is on each of plate sidepiece 32.Relatively perforate of substantial middle at plate sidepiece 32.Have again, on plate sidepiece 32, having and forming the slot part 36 of コ font with the opposite side that the rotation axis of fastening connecting hole 35 forms arm 33.This slot part 36 becomes plate sidepiece 32 and ends plate main body 31 opposite sides by being processed into to lead to, in order to allow the fastening teat that is arranged on the pressure strip 5 enter.
Shell 2 is made of square tabular and its central shape with grooving, and makes with the resin with insulating properties as shown in Figure 2.And the mode with inside one deck step-down of shell 2 forms by along interior week stage portion 22 being set as the frame section 21 of peripheral part of shell 2.In addition, in an end of shell 2 stage portion 22 is not set, and to do lowlyer with the bottom of stage portion 22 as the mode of same level, from the side of this end, shell is made the upward コ font of opening.Between this end of covering upper part of the cover metallic plate 3 and shell 2, form the space 23 of clamping storage card MC.
Have again, hold 26 sides to rotate in the rotation relative with the end that is provided with space 23 and connecting freely metallic plate 3.That is, shell 2 is provided with the rotational axis hole 25 that rotation engages metallic plate 3 freely on the side 24a, the 24b that have between the end that is provided with space 23 and the end relative with it.Rotational axis hole 25 the end side opposite with space 23 of side 24a, 24b respectively relatively perforate be arranged to identical shape.At this, describe as an example of the rotational axis hole 25 on the 24a of side, opened example.
Like this, by being made, can move in rotational axis hole 25 interior slips the rotation teat 34 of metallic plate 3, although metallic plate 3 can not be rotating rotation centered by the teat 34 when being positioned at the first hole 25a rotating teat 34, can make metallic plate 3 when teat 34 is positioned at the second hole 25b storage card MC can come in and go out to rotate rotation centered by the teat 34 rotating.
The contact 4 that is fixed on the shell 2 has the structure identical with the past, by the elongated metallic plate that belongs to good conductor being carried out bending and bending machining forms, make simultaneously institute's bar by pressure processing, and utilize the mould of shell 2 when being shaped, to be fixed on integratedly on the shell 2 simultaneously.Contact 4 is shown in Fig. 2 waits, and pars intermedia 41 is formed on the shell 2, end the space of shell 2 23 sides form be positioned at below 2b side and the soldering fixed part 42 that is electrically connected and fixes with other electronic unit such as printed circuit board (PCB) (not shown).The following 2b of the position of this soldering fixed part 42 and shell 2 is same level or gives prominence to a bit a little.In addition, contact 4 is forming splicing ear section 43 with the end of soldering fixed part 42 opposite sides.Splicing ear section 43 forms agley in the outstanding mode of 2a above shell 2, thereby makes storage card MC be installed on the shell 2 and have the elastic force that can be electrically connected with the contact section (not shown) of storage card MC with good contact.And contact 4 forms when forming shell and being connected of storage card MC needed quantity and being fixed.In addition, contact 4 does not have anything to change with the contact 4 of implementing in the past, as long as the contact of right quantity suitable shape is set.
On shell 2, similarly be fixedly installed integratedly pressure strip 5 with contact 4.Compressing blackboard newspaper 5 forms metallic plate through pressure processing, it is as one man forming along the mode of configuration around the shell 2 and the shape of frame section 21, by forming under the state that is positioned at shell 2 inside at the position that makes regulation, thereby shell 2 is given the metal rigidity of pressure strip 5, and then the regulation position is exposed slightly highlightedly from following 2b, and can utilize soldering etc. to be connected and fixed when being electrically connected with printed circuit board (PCB) (not shown).Pressure strip 5 is arranged on rotational axis hole 25 parts of side 24a, the 24b of shell 2 at the sidepiece that will configure along the frame section 21 of shell 2 shown in Fig. 1 and Fig. 2 etc., form axial region stiffener 51 in the mode along side 24a, 24b from following 2b bending ground.Axial region stiffener 51 has the reinforced hole 52 in the outside of the rotational axis hole 25 that can be fitted to shell 2.Therefore, aperture efficiency rotational axis hole 25 tips of this reinforced hole 52 are large, peripheral part that makes rotational axis hole 25 at shell 2 from the side 24a, 24b is outstanding and edge part 27 is formed the bead shape, and edge part 27 and reinforced hole 52 are chimeric and form reinforced hole 52 in the mode of stiffened edge edge 27 peripheral part.Like this, edge part 27 by making shell 2 and the reinforced hole 52 of pressure strip 5 are chimeric, by giving around the rotational axis hole 25 of the relatively poor shell of its intensity 2 as the mechanical strength of the metal rigidity of pressure strip 5, thereby when the metallic plate 3 by the rotation projection 34 of metallic plate 3 and rotational axis hole 25 pivot suspensions rotates, can not destroy rotational axis hole 25 ground and be strengthened.
In addition, pressure strip 5 is in the centre position separately of the side of shell 2 24a, 24b, with axial region stiffener 51 similarly along side 24a, 24b ground is from the bending of following 2b side and form plate fixed part 53.Plate fixed part 53 is arranged to, when metallic plate 3 with covering shell 2 above the mode of 2a when being in closed condition, it is in the position relative with the fastening connecting hole 35 of metallic plate 3.This plate fixed part 53 is arranged to, and the side 24a that is in shell 2 of plate fixed part 53, the part of 24b form concavity, makes it be exposed to side 24a, 24b surface.Have again, be provided with teat at the middle body of plate fixed part 53.Like this, by plate fixed part 53 is set, carries out fastening and realize being electrically connected thereby can utilize in the fastening connecting hole 35 that enters metallic plate 3 and be provided with elastic force that the part plate sidepiece 32 of the fastening connecting hole 35 of metallic plate 3 has.
Have, the following 2b side of the outside shell 2 in a plurality of regulations position of pressure strip 5 is exposed again, and the electronic unit of formation and printed circuit board (PCB) (not shown) etc. carries out the compressed part 54 of ground connection.This compressed part 54 is arranged in the present embodiment, space 23 sides of the substantial middle section below setting arranges axial region stiffener 51 between 2b side, the stiffener 51,51 and frame section 21 be exposed to respectively frame section 21 below 2b.Therefore, pressure strip 5 is so that compressed part 54 and following 2b are in same level or outstanding slightly mode forms compressed part 54 to following side bending ground, and forms with shell 2.In addition, in the present embodiment, although be formed as described above compressed part 54, as long as also setting consistent with the shape of implementing is in position.
In addition, pressure strip 5 is by forming concurrently the reinforcement bending part (not shown) that is bent into the L font with the side of shell 2 in the length range in being formed with the frame section 21 of side 24a, 24b, also hold 26 sides to form similarly in the rotation of frame section 21 and strengthen bending part (not shown), form the shell rib of L font in the inside of frame section 21, thereby shell is further strengthened.In addition, if pressure strip 5 to major general's metallic plate is set to shaped as frame, thereby the reinforced hole 52 that will be arranged on both sides is interconnected between the rotational axis hole 25 of frame section 21, when metallic plate 3 is rotated, even the power to rotational axis hole 25 partial actions traction upward and so on, owing to shell 2 compacted plates 5 are strengthened being not easy distortion, thereby can eliminate the rotation teat 34 of metallic plate 3 from the problem of rotational axis hole 25 disengagings and so on.
Card connector for memory card 1 in the above-described embodiments, although contact 4 and pressure strip 5 and shell 2 is integrally formed and be fixed on the shell 2, also can make and arrange the fastening section of shell 2 and chimeric fixing with shell 2.
The card connector for memory card 1 that forms as mentioned above rotates the rotation teat 34 of metallic plate 3 under the state of the second hole 25b that is positioned at the rotational axis hole 25 that is arranged on the shell 2,23 sides are opened wide greatly in the space, and the top 2a that makes shell 2 exposes and storage card MC is placed on above this on 2a.At this moment, the contact section (not shown) of storage card MC positions with the 22 couples of storage card MC of stage portion of the mode shell 2 in the splicing ear section 43 that is positioned at contact 4 and is located on the top 2a.
When storage card MC has been placed into assigned position, realize good being electrically connected in order to make storage card MC and contact 4, metallic plate 3 is rotated and be in and make storage card MC should push from the top closed condition of contact 4 sides.At this moment, since the rotation teat 34 of metallic plate 3 be positioned at the second hole 25b of rotational axis hole 25 and can rotate.
When metallic plate 3 is rotated covering shell 2 above the time, because it is consistent with the longer dimensional directions of the first hole 25a to rotate the longer dimensional directions of teat 34, and the shorter dimensional directions of rotating teat 34 is consistent with the shorter dimensional directions of the first hole 25a, thereby rotation teat 34 is in the position that can enter in the first hole 25a.
In addition, when rotation teat 34 is positioned at the second hole 25b of rotational axis hole 25, be arranged on the plate fixed part 53 of pressure strip 5 that slot part 36 on the metallic plate 3 is positioned at the side 24a, the 24b that are in shell 2, during 2a, then plate fixed part 53 enters into slot part 36 on covering shell 2.
Under this state, make metallic plate 3 above shell 2 2a 23 Slideslips move to the space.At this moment, because the shorter dimensional directions of rotation teat 34 is consistent with shorter dimensional directions and the longer dimensional directions of the first hole 25a with longer dimensional directions, thereby be in slidably state.
When rotation teat 34 enters in the first hole 25a, because the slot part 36 of metallic plate 3 is also mobile, thereby the plate fixed part 53 of pressure strip 5 pushes away the plate sidepiece 32 of metallic plate 3 on still and enters downside (shell side 24a one side of plate sidepiece 32), makes the plate fixed part 53 of pressure strip 5 enter into fastening connecting hole 35 by further slip.At this moment, plate fixed part 53 is connected with splicing ear section 43, is extruded and connects and also form good connection aspect electric because plate fixed part 53 is subject to elastic force that some deflections of the plate sidepiece 32 of metallic plate 3 produce.Certainly, metallic plate 3 easily slides, and rotates teat 34 in fact also by fastening and can not be to the second hole 25b side shifting of rotational axis hole 25.
And metallic plate 3 is owing to being electrically connected with the plate fixed part 53 of pressure strip 5, thereby, can bring into play good shield effectiveness in the information reception of storage card MC and contact 4 and the transmission.
When taking out storage card MC, make metallic plate 3 to rotating end 26 Slideslips, and remove plate fixed part 53 with to being connected of fastening connecting hole 35, thereby make plate fixed part 53 be arranged in groove 36.At this moment, owing to rotate the second hole 25b that teat 34 enters into rotational axis hole 25, thereby metallic plate 3 is in rotation state freely.
So, become open mode so that the free end side with the opposite side of rotation axis formation arm of metallic plate 3 is rotated away from the mode of top 2a.At this moment, if operating personnel apply excessive power and make its rotation, pressure strip 5 do not strengthen rotational axis hole 25 peripheral part and not about rotational axis hole between scope in the existing example of connection reinforcement, as shown in Figure 5, the rotation teat 34 that has been out of shape of 25 of two rotational axis holes of the deflection of A section and shell 2 will produce the problem that breaks away from and so on from rotational axis hole 25.But, in the present embodiment, owing to pressure strip 5 strengthen rotational axis hole 25 peripheral part and about rotational axis hole between scope in connect and strengthened shell, thereby, can not produce deflection as shown in Figure 5, produce the situation of the problem that metallic plate 3 breaks away from and so on from rotational axis hole 25 seldom.
In addition, in rotating teat 34 and enter into the first hole 25a of rotational axis hole 25 and with storage card MC folding and unfolding to and shell 2 between state under, because the plate main body 31 of metallic plate 3 is pushed storage card MC to shell 2 sides, thereby, the splicing ear section 43 of contact 4 and the contact section (not shown) of storage card MC are though can electrically contact with good contact, but such structure is identical with the past also, also can adopt a part of grooving that will dig main body 31 to become the コ font and to shell 2 side bendings, with the elastic force that metallic plate was had that forms plate main body 31 with storage card MC to other methods such as shell 2 side extruding.
