Above-mentioned fixed part 61 contributes to pin connector 2 fixing with respect to this circuit substrate by being welded to connect in the corresponding portion (not shown) of circuit substrate.In addition, as shown in Fig. 7 (B) and Fig. 8 (B), the above-mentioned board 62 that turns back is contained in the maintenance recess 45A that is held in plug side shell 40 in the internal face side of end wall 45 that is the chimeric surface side of formation incorporating section 46.For this board 62 that turns back, two boards that formation is parallel to the face of above-mentioned internal face turn back in the lower end that this turns back board 62, and be arranged to on connector Width, extend turn back 62DWei border, edge and on above-mentioned terminal board column direction opposite one another.In the present embodiment, in two boards of the above-mentioned board 62 that turns back, be called " along board 62A " along the face that comprises above-mentioned internal face and upper end with the board that above-mentioned fixed part 61 links by being configured in terminal board column direction outside (left side of Fig. 7 (B)), will inside terminal board column direction, (right side of Fig. 7 (B)) be called " parallel board 62B " at the above-mentioned board configuring abreast along the opposition side of board with 62DWei border, turned-back edge edge.
As shown in Fig. 7 (B) and Fig. 8 (A), Fig. 8 (B), for along board 62A and parallel board 62B, being formed with respectively at the same position when terminal board column direction is observed the 62C(of hole portion that connects in thickness of slab direction also can be with reference to Fig. 2).In the present embodiment, these two 62C of hole portion complement each other, thereby as for bringing into play function (with reference to Fig. 7 (B)) with the locked 62C-1 of portion of sticking department 33 engagements of supporting locking metalwork 30.In addition, as shown in Fig. 8 (A), in the edge, both sides that is formed on the plate thickness surface of extending along the vertical direction along the both sides of board 62A, outstanding be formed with carry out engagement in the maintenance recess 45A that the board 62 that turns back is pressed into plug side shell 40 time and keep be pressed into teat 62A-1.
In addition, in locking metalwork 60 under posture as shown in Figure 8, for parallel board 62B, the upper end position of the edge, both sides of the plate thickness surface of extending along the vertical direction being formed on the both sides of this parallel board 62B, outstanding being formed with for prevent from locking the stop teat 62B-1 that metalwork 60 departs from the time that connector is surprisingly extracted.For this stop teat 62B-1, under state in the board 62 that turns back is maintained at the maintenance recess 45 of plug side shell 40, being positioned at can for example, in the position of extracting the upper engagement of direction (below of Fig. 7 (B)) of socket connector 1 with respect to the stop end difference (not shown) that is formed at this maintenance recess 45.If the pin connector 2 under jogged state of connector is subject to unexpected withdrawal force, act on locking metalwork 60 towards the above-mentioned withdrawal force of extracting direction of socket connector 1.Now, the stop teat 62B-1 of parallel board 62B is with respect to the above-mentioned stop end difference engagement of plug side shell 40, therefore, can prevent from locking metalwork 60 and extract extracting of direction towards above-mentioned.
By the bottom surface side from diapire 41 (top of Fig. 7 (B)) is pressed into and keeps in recess 45A via through hole 41A by the board 62 that turns back, thereby locking metalwork 60 is installed on to plug side shell 40.Under the state of installation, snap in respect to the obverse both sides of the conduct inner edge portion of extending along the vertical direction of above-mentioned maintenance recess 45A along the teat 62A-1 that is pressed into of board 62A, prevent from thus locking extracting of metalwork 60.In addition, the plate face of above-mentioned parallel board 62B exposes (also can with reference to Fig. 2) towards incorporating section 46 to be formed as the mode of the same face with the internal face of this end wall 45.
Next, with reference to Fig. 1 and Fig. 7 (A), Fig. 7 (B), the chimeric action of connector of socket connector 1 and pin connector 2 is described.First, socket connector 1 and pin connector 2 are installed on respectively to corresponding circuit substrate by the mode being welded to connect.Then, as shown in Figure 1, make socket connector 1 be formed as incorporating section 16 posture upward, and, above this socket connector 1, make the incorporating section 46(of pin connector 2 with reference to Fig. 2) be formed as posture downward.
Next, keep the posture of Fig. 1 and pin connector 2 is declined, the prominent wall 12 that makes socket connector 1 enters in the incorporating section 46 from below towards pin connector 2, and the perisporium 43 that makes pin connector 2 enters in the incorporating section 16 from top towards socket connector 1.Its result, the contact site 21 of the supporting terminal 20 of socket connector 1 and locking teat 23A enter respectively and be limited in the contact recess 52 of terminal 50 of pin connector 2 and in locked recess 53, thereby realized terminal electrically contacting and extracting the locking of direction (top) towards connector each other.
In addition, in the chimeric process of connector, the lower end of the board 62 that turns back of locking metalwork 60 is connected to the upper limb (inclination edge) of the sticking department 33 of supporting locking metalwork 30, and this sticking department 33 is pressed towards the pressing force of terminal board column direction inner side.If sticking department 33 is subject to above-mentioned pressing force, this sticking department 33 is as shown in the dotted line in Fig. 7 (A), and inwardly the bottom land 18B-2(of slot part 18B is with respect to rectangular of terminal board column direction.Also can be with reference to Fig. 4) side shifting, and be incorporated in interior slot part 18B.Now, allow the movement of sticking department 33 because of the strain of the prolongation arm 31C of supporting locking metalwork 30.Particularly, as shown in the dotted line in Fig. 7 (A), the 31C-1 of strain portion that extends arm 31C using near the boundary position with respect to maintained portion 31C-2 as fulcrum and towards terminal board column direction inner side, in other words, strain occurs the inclined plane 18A-1 of slot part 18A outward.Its result, the mode approaching each other with the linking part 31A-1 of supporting locking metalwork 30 is carried out displacement, rise part 32 and the sticking department 33 bottom land 18B-2 side shifting of slot part 18B towards above-mentioned terminal board column direction inner side that is inwardly.
In addition, if the edge 62D that turns back that is positioned at lower end of board 62 of turning back above-mentioned is connected to the upper limb of above-mentioned sticking department 33, because the upper limb that is subject to pressing force of this sticking department 33 is inclination edge, so, except being subject to, towards the pressing force of the component of above-mentioned terminal board column direction inner side, being also subject to the pressing force of component downward.But, in the present embodiment, the limiting unit 18B-1A of socket side shell 10 is positioned at the position that can be limited the 32A of portion engagement below the 32A of the portion that is limited of supporting locking metalwork 30 with this, thereby limit the movement downward of supporting locking metalwork 30, therefore, prevented supporting locking metalwork 30 extracting from socket side shell 10.
As mentioned above, sticking department 33 is received in slot part 18B inwardly, thereby allows pin connector 2 further to decline.And, as shown in Fig. 7 (B), if locking metalwork 60 the 62C of hole portion arrive supporting locking metalwork 30 sticking department 33 position and make this sticking department 33 being released on from above-mentioned pressing force, as shown in the solid line in Fig. 7 (A), Fig. 7 (B), extend arm 31C and be released from elastic deformation, thereby utilize this elastic restoring force and return to free state.Its result, as shown in the solid line in Fig. 7 (B), sticking department 33 enters in the 62C of hole portion, is positioned at respect to the locked 62C-1 of portion, the lower edge of the 62C of hole portion can be extracted the position of direction (top) engagement and be formed as lock-out state towards connector.
In the present embodiment, the board 62 that turns back is positioned at the inwall side of end wall 45 that is the chimeric surface side of a side of plug side shell 40., because the board 62 that turns back is not crossed over end wall 45, so position that can be near each other on terminal board column direction will be arranged to mutually opposed along board 62A and the 62B of parallel-plate portion.Like this, approach along the position of board 62A by parallel board 62B is arranged at, can dwindle the locked 62C-1 of portion of parallel board 62B and be held in plug side shell 60 along the distance between board 62A.Therefore, even if pin connector 2 effects under jogged state of connector are had to extracting the external force of direction and making the locked 62C-1 of portion of above-mentioned parallel board 62B be subject to above-mentioned withdrawal force towards connector as unexpected withdrawal force, because above-mentioned distance is very little, correspondingly, be difficult to produce flexural deformation at the board 62 that turns back, so also can prevent from locking the breakage of metalwork 60.
In addition, although above-mentioned withdrawal force also acts on the locked 62C-1 of portion along board 62A, but this is held in plug side shell 40 along board 62A by being pressed into teat 62A-1, this distance on above-mentioned terminal board column direction that is pressed between teat 62A-1 and above-mentioned sticking department 62C-1 is zero, so can not occur bending and deformation at the board that turns back, can prevent from locking the breakage of metalwork 60.
And, in the present embodiment, the locked 62C-1 of portion of locking metalwork 60 two boards of the board 62 that turns back of locking metalwork 60 that is outside board 62A and interior board 62B, be formed as the edge of the hole portion connecting with identical diameter at same position, so compare with the situation that only at a board, locked portion is set, the scope of part that can engagement with respect to the sticking department 33 of supporting metalwork 30 becomes the total amount of two thicknesss of slab and increases exponentially, therefore, correspondingly, can improve reliability and the stability of lock-out state.Although in the present embodiment locked portion is arranged to two boards, can certainly makes lock-out state more stable by locked portion being arranged to 3 above boards.
In addition, in the present embodiment, give prominence to from forming this edge, both sides along the plate thickness surface of board 62A along the teat 62A-1 that is pressed into of board 62A.That is, do not project upwards in thickness of slab side owing to being pressed into teat 62A-1, so can make along the plate face of board 62A and the 62B of parallel-plate portion more approaching each other.Its result, the board 62 that turns back is difficult to deform, thereby can prevent from more reliably locking the breakage of metalwork 62.In addition, because the above-mentioned teat 62A-1 that is pressed into does not give prominence in above-mentioned thickness of slab direction, therefore, correspondingly, can guarantee the wall thickness of end wall 45, thereby can maintain the larger intensity of this end wall 45.
Like this, terminal 20,50 connected each other and then locked, and supporting locking metalwork 30,60 is locked to each other, thereby completing the chimeric action of connector.As mentioned above, be provided with upper wall 12A at the prominent wall 12 of socket side shell 10, the upper limb of the rise part of this upper wall 12A and supporting locking metalwork 30 opposed and be positioned at can with the position of this upper limb engagement.Therefore, under jogged state of connector, even if pin connector 2 is extracted direction (top) and is unexpectedly lifted towards connector, because the upper limb of above-mentioned rise part 32 is limited to the lower surface of above-mentioned upper wall 12A, so also can limit the displacement on the top of above-mentioned rise part 32.Its result, the engagement state between the sticking department 33 of supporting locking metalwork 30 and the locked 62C-1 of portion of locking metalwork 60 is maintained, thereby can maintain stable lock-out state.
In addition, as mentioned above, the rise part 32 of supporting locking metalwork 30 and base arm 31A utilize from the outstanding opposed faces of the outstanding protuberance 18B-1 of the opposed internal face of interior slot part 18B and are limited in the position connector Width, so can guarantee reliably the engagement state of above-mentioned sticking department 33 and the above-mentioned locked 62C-1 of portion, thereby can maintain stable lock-out state.
Next, with reference to Fig. 7 (A), Fig. 7 (B), to connector, pull action describes.In the time extracting with respect to socket connector 1 pin connector 2 under jogged state of connector, press towards terminal board column direction inner side socket connector 1 supporting locking metalwork 30 latch-release operating portion 31B and remove operation.If latch-release operating portion 31B is subject to as the pressing force towards above-mentioned terminal board column direction inner side of removing operating physical force, upwards there is strain the party in the 31C-1 of strain portion that extends arm 31C.And, the same with the explanation of the chimeric process of above-mentioned connector, the linking part 31A-1 of supporting locking metalwork 30 is each other with mode displacement near each other, and rise part 32 and sticking department 33 are towards above-mentioned terminal board column direction inner side that is towards the bottom land 18B-2 of interior slot part 18B side shifting (with reference to the dotted line of Fig. 7 (A), Fig. 7 (B)).
Its result, sticking department 33 is incorporated in interior slot part 18B, and the lock-out state that the locked 62C-1 of portion of this sticking department 33 and the locking metalwork 60 of pin connector 2 can engagement is disengaged.And, by being extracted to direction (top) towards connector, pin connector 2 lifts, and this pin connector 2 is easily pulled out, thereby completes connector pull action.
