As mentioned above, locking metalwork 80 for the related pin connector 2 of present embodiment, two locked foots 82,83 are configured to along the inside and outside two ends wall of each end wall 65 of plug side shell 60, in any one party of locked foot 82,83, are all formed with the locked 82D-1 of portion, 83D-1.Therefore, even if make socket connector 1 form the posture that the posture left and right reversion shown in Fig. 5, Fig. 6 is obtained, also can supporting locking metalwork 30 lockings with socket connector 1 by the locking metalwork of pin connector 2 80.In this case, by the locked 83D-1 of portion in outside of a distolateral locking metalwork 80 and the locked 82D-1 of portion in another distolateral inner side as locked portion.

Turn back to the explanation to plug side shell 60.Examine Fig. 2 known, at the upper wall surface (lower surface in Fig. 1, Fig. 6) of end wall 65, for taking in the recess 65A of base portion 81 of locking metalwork 80, form the slot part that extends along connector Width and slot part along the extension of terminal board column direction and intersect such criss-cross recess.End wall surface in the inner side of end wall 65, also can be with reference to Fig. 7 (B) for taking in the interior slot part 65B(of the locked foot 82 in inner side of locking metalwork 80) with above-mentioned recess 65A continuously and extend along the vertical direction and form.End wall surface in the outside of end wall 65, also can be with reference to Fig. 7 (B) for taking in the outer slot part 65C(of the locked foot 83 in outside of locking metalwork 80) with above-mentioned recess 65A continuously and extend along the vertical direction and form.At the side wall surface of end wall 65 that is be positioned at the face on the extended line of outer surface of sidewall 64 on terminal board column direction, continuous and extend along the vertical direction and form with above-mentioned recess 65A for the side groove portion 65D of shielding connecting portion 84 that takes in locking metalwork 80.

By locked foot 82,83 respectively the top from Fig. 2 be pressed into interior slot part 65B and outside in slot part 65C, thus locking metalwork 80 is installed on to plug side shell 60.Installing under the state finishing, the locked foot 82 in base portion 81, inner side of locking metalwork 80, the locked foot 83 in outside and shielding connecting portion 84 are incorporated in respectively in the recess 65A of plug side shell 60, interior slot part 65B, outer slot part 65C and side groove portion 65D.In addition, what be held board 82C, 83C is pressed into teat 82C-1,83C-1(all with reference to Fig. 7 (A)) be clamped into the both sides inner edge extending along the vertical direction of interior slot part 65B and outer slot part 65C, prevent from thus locking metalwork 80 and come off.

Terminal 70 is bent upwards and makes in thickness of slab side by making that metallic plate is carried out to the die-cut banded sheet obtaining.As shown in Figure 1 and Figure 2, for this terminal 70, by the molded mode of Integral mold, be held in each sidewall 64 of plug side shell 60, and with equal intervals, arrange on the long side direction of this sidewall 64.This terminal 70 has: the connecting portion 71 of comparing the roughly the same height and position straight shape that stretch out in outside from sidewall 64 towards connector Width at the diapire 61 with plug side shell 60; And with this connecting portion 71 continuously and towards the top (below in Fig. 1) in Fig. 2 crooked and buried underground be held in above-mentioned sidewall 64 contact arm 72.This contact arm 72 extends along the medial surface of above-mentioned sidewall 64, and so that the plate face of this contact arm 72 and the medial surface of this sidewall 64 form coplanar mode towards receiving portion 66, exposes.At the plate face exposing of this contact arm 72, in the mode of slave plate face depression, be formed with contact recess 72A, this contact recess 72A for accept socket connector 1 terminal 20 contact teat 22A and contact teat 22A with this and contact.

Next, in conjunction with Fig. 1 and Fig. 6, the chimeric action of connector of socket connector 1 and pin connector 2 is described.First, by the mode of brazing, socket connector 1 and pin connector 2 are installed on to each self-corresponding circuit substrate.Next, as shown in Figure 1, make socket connector 1 form receiving portion 16 towards the posture of top, and, above this socket connector 1, make the receiving portion 66(of pin connector 2 with reference to Fig. 2) form posture downward.

Next, the posture that maintains Fig. 1 makes pin connector 2 decline unchangeably, in the receiving portion 66 of the prominent wall portion 12 that makes socket connector 1 from below towards pin connector 2, enter, and enter in the receiving portion 16 of the perisporium 63 that makes pin connector 2 from top towards socket connector 1.Its result, makes in the contact recess 72A of the outstanding terminal 70 that enters into pin connector 2 of the contact teat 22A of supporting terminal 20 of socket connector 1, thereby realizes terminal electrically contacting each other.

In addition, in the chimeric process of connector, the lower end that is arranged at two of pin connector 2 locking metalworks 80 is illustrated by solid line respectively with sticking department 35A, the 35B(Fig. 6 of supporting locking metalwork 30 in latched position) upper limb (inclination edge) butt, on terminal board column direction this sticking department 35A, 35B are pressed towards the pressing force of another distolateral (the right-hand member side in Fig. 6).For sticking department 35A, 35B, if be subject to above-mentioned pressing force, as shown in phantom in Figure 6, towards other end side shifting (retreating), be incorporated in respectively in the first prominent wall slot part 18D, in the second end wall slot part 18C and arrive latch-release position together with rising portions 32A, 32B.Now, the movement of sticking department 35A, 35B is because of elastic deformation part 40 strain (compression) that is being allowed to towards another distolateral strain of elastic arm 41,42.

As mentioned above, make sticking department 35A, 35B arrive latch-release position, allow thus pin connector 2 further to decline.And, as shown in Figure 6, if the 83D of hole portion of the locked foot 83 in outside of the locking metalwork 80 of the 82D of hole portion of the locked foot 82 in inner side of the locking metalwork 80 of distolateral (left end side in Fig. 6) and another distolateral (the right-hand member side in Fig. 6) arrives the sticking department 35A of locking metalwork 30, the position of 35B, this sticking department 35A, 35B are discharged from above-mentioned pressing force.Its result, elastic deformation part 40 elastic arm 41,42 returns to initial latched position to reduce elastic deformation amount's mode towards a distolateral recovery.As shown in the solid line in Fig. 6, the sticking department 35A, the 35B that turn back to latched position enter respectively in the above-mentioned hole 82D of portion, 83D, with respect to the locked 82D-1 of portion, 83D-1(with reference to Fig. 7 (A), Fig. 7 (B)) that is the lower edge of the 82D of hole portion, 83D be positioned at and can extract the position that direction (top) locks and form lock-out state towards connector.

In addition, as shown in Figure 8, the shielding tongue piece 55 of the shield member 50 of corresponding respectively socket connector 1 is pressed and made them that strain occur towards connector Width outside, make thus the shielding connecting portion 84 of the locking metalwork 80 of pin connector 2 contact with this shielding tongue piece 55 with contact.

Like this, terminal 20,50 is interconnected with one another, locking metalwork 30,80 is locked to each other, make to shield tongue piece 55 and interconnect with shielding connecting portion 84, complete thus the chimeric action of connector.Under jogged state of connector, even if unexpectedly pin connector 2 being extracted to direction (top) towards connector lifts, due to rising portions 32A, 32B and be limited the 34A of portion, 34B upper limb separately and restriction face 18D-2,18C-2,18B-2, the 18E-2 butt of socket side shell 10, so also can limit the movement towards top of supporting locking metalwork 30.Its result, can maintain sticking department 35A, the 35B of supporting locking metalwork 30 and the locked 82D-1 of portion of locking metalwork 80, the locking state of 83D-1, thereby can maintain stable lock-out state.

Next, in conjunction with Fig. 6, to connector, pull action describes.When the pin connector of the jogged state of connector in respect to socket connector 12 is extracted, on terminal board column direction towards another is distolateral (in Fig. 6 right-hand) press socket connector 1 supporting locking metalwork 30 latch-release operating portion 36 and remove operation.If latch-release operating portion 36 be subject to as remove operating physical force towards above-mentioned another distolateral pressing force, elastic deformation part 40 carries out strain in the same direction.And identical with situation about illustrating in the chimeric process of connector above-mentioned, elastic deformation part 40 carries out strain in compressed mode, make sticking department 35A, 35B together with rising portions 32A, 32B towards above-mentioned other end side shifting.

Its result, sticking department 35A, 35B are incorporated in the first prominent wall slot part 18D, in the second end wall slot part 18C and arrive latch-release position (with reference to the dotted line in Fig. 6), and the locked 82D-1 of portion, the 83D-1(of the locking metalwork 80 of this sticking department 35A, 35B and pin connector 2 is with reference to Fig. 7 (A), Fig. 7 (B)) lock-out state that can lock is disengaged.And, towards connector, extract direction (top) and lift pin connector 2, thus this pin connector 2 is extracted like a cork, thereby completed connector pull action.

For supporting locking metalwork 30, rising portions 32A, 32B are positioned at the first prominent wall slot part 18D, the second end wall slot part 18C, and sticking department 35A, 35B give prominence to from the top of above-mentioned rising portions 32A, 32B and be positioned at receiving portion 16.That is, rising portions 32A, 32B and sticking department 35A, 35B are positioned at the scope of this socket side shell 10 and move in this scope on the long side direction of terminal board column direction that is socket side shell.Therefore, even if guaranteed the larger overhang of sticking department 35A, 35B, no matter whether configured locking metalwork 30, also can both easily guarantee the space that allows this sticking department 35A, 35B and rising portions 32A, 32B to move in the above-mentioned scope originally existing on above-mentioned terminal board column direction, therefore, can on above-mentioned terminal board column direction, avoid the maximization of connector.In addition, in the present embodiment, do not carry out bending machining, but maintain with respect to the rectangular plate face of connector Width, make supporting locking metalwork 30.Therefore, as long as the sidewall 14 of the size of thickness of slab of guaranteeing supporting locking metalwork 30 on this connector Width in identical connector Width direction scope each other, so, even also can avoid the maximization of connector in identical connector Width direction.

In addition, in the present embodiment, because elastic deformation part 40 strain allows the movement of supporting locking metalwork 30 on terminal board column direction.Like this, 40 of elastic deformation parts that are different from supporting locking metalwork 30 by setting are without making sticking department 35A, 35B itself have elasticity, therefore, can improve rigidity and the intensity of sticking department 35A, 35B itself, thereby can access stable lock-out state.In addition, by increasing the overhang of sticking department 35A, 35B, can further improve rigidity and the intensity of this sticking department 35A, 35B, so can realize the further raising of the stability of lock-out state.

As mentioned above, in the present embodiment, two locked foots 82,83 of locking metalwork 80 are configured to along the inside and outside two ends wall of the end walls 65 of plug side shell 60, in any one party of locked foot 82,83, are all formed with the locked 82D-1 of portion, 83D-1.Therefore, the pin connector 2 of present embodiment is not limited to the connector of the form of socket connector 1 inner side such, that be sticking department 35A, the 35B distolateral and end wall 15 that another is distolateral that is arranged at respectively prominent wall portion 12, and sticking department can further lock with respect to the mating connector in diverse location setting.

For example, in the situation that socket connector have from the end walls of socket side shell medial surface separately towards terminal board column direction in side-prominent sticking department, the locked 83D-1 of portion in each outside of locking metalwork 80 that is arranged at the end walls 65 of pin connector 2 is used as locked portion.In addition, in the situation that socket connector does not have outstanding sticking department outside the end walls of the prominent wall portion of socket side shell faces terminal board column direction, the locked 82D-1 of portion in each inner side of locking metalwork 80 that is arranged at the end walls 65 of pin connector 2 is used as locked portion.

In addition, socket connector is that the perisporium embed wholly of socket side shell is to the connector in the receiving portion 66 of pin connector 2, in the situation that outstanding sticking department outside having from the end walls of above-mentioned socket side shell lateral surface separately towards terminal board column direction, the locked 82D-1 of portion in each inner side of locking metalwork 80 that is arranged at the end walls 65 of pin connector 2 is used as locked portion.

Like this, the pin connector 2 related according to present embodiment, even for the socket connector of the different various forms in sticking department position, also can optionally be locked by a kind of locking metalwork 80.Its result, can expand the amplitude of the form of the mating connector that can tackle.

In the present embodiment, the above-mentioned locked 82D-1 of portion of locking metalwork 80, 83D-1 is in the locked foot 82 of locking metalwork 80, 83 two boards separately, expose board 82A, 83A and be held board 82C, 83C forms the edge of the hole portion connecting with same diameter in same position, so, with the situation comparison of locked portion is only set at a board, can with the sticking department 35A of supporting locking metalwork 30, the scope of the part that 35B locks becomes the amount of two thicknesss of slab and doubles, correspondingly, can improve reliability and the stability of lock-out state.In the present embodiment, although locked portion is arranged to two boards, can certainly be arranged at three above boards, can make thus lock-out state further stable.In addition, as long as just can guarantee enough locking locking amounts with the thickness of slab size of a board, so can also be only exposing that board 82A, 83A form hole portion and using the edge of this hole portion as locked portion.

< the second execution mode >

In the first embodiment, the locked 82D-1 of portion, the 83D-1 of the locking metalwork 80 of pin connector 2 is arranged at the 82D of hole portion of locked foot 82,83, the edge of 83D, but in the second execution mode, locked portion forms from the outstanding protuberance of the plate face of locked foot, and this point is different from the first execution mode.Fig. 9 is the cutaway view shown in a part for the related socket connector of the second execution mode and pin connector is amplified, and utilizes with respect to the cross section in rectangular of connector width side and shows the locking metalwork of pin connector of a distolateral setting and the lock-out state of the supporting locking metalwork of socket connector at terminal board column direction.For the shape of the pin connector 102 of the second execution mode, except the above-mentioned locked 182D of portion, 183D, all the other are all identical with the pin connector 2 of the first execution mode, therefore, for identical part, be labeled in and on the basis of Reference numeral of the first execution mode, add the Reference numeral of " 100 " and the description thereof will be omitted.

As shown in Figure 9, the locked 182D of portion, the 183D of locking metalwork 180 form the outstanding protuberance of plate face that exposes board 182A, 183A from locked foot 182,183.The above-mentioned locked 182D of portion, 183D are for example by carrying out punch process and form exposing board 182A, 183A.Under jogged state of connector, as shown in Figure 9, the above-mentioned locked 182D of portion, 183D are being arranged at the sticking department 135A of the supporting locking metalwork 130 of socket connector 101, the lower position of 135B, are arranged to extract direction (top) towards connector and lock with this sticking department 135A, 135B.

The shape of the locked portion of pin connector is not limited to the such hole portion of the first execution mode, the such protuberance of the second execution mode, for example can be not the board that exposes of locked foot is not connected but forms the recess that exposes the plate face depression of board from this.In such mode, form and with respect to rectangular of connector plugging direction (pin connector, from the chimeric situation in top, is downside internal face), as locked portion, bring into play function in the internal face of this recess.

In the first and second execution mode, the lower edge of the sticking department of supporting locking metalwork roughly extends with respect to above-below direction with meeting at right angles, but also can instead have the inclination edge that square neck is oblique along with trend front end on terminal board column direction upward.When inclination edge being arranged in the situation of sticking department with which, if when extracting connector with withdrawal force more than constant basis towards above lift pin connector, above-mentioned locked portion from below inclination edge (lower edge) butt with above-mentioned sticking department in latched position, and towards latch-release position, press this sticking department on terminal board column direction.Its result, because the strain of elastic deformation part or strain portion allows the movement towards latch-release position of above-mentioned sticking department, lock-out state is removed, and therefore, pin connector can be extracted.That is, only by lifting the operation of pin connector, just can extract this pin connector, so without latch-release operating portion being arranged to supporting locking metalwork.Such mode is preferably applied to lock the connector that intensity is not too large.In addition, when replacing the lower edge of sticking department, at the rising wood of locked portion or when the rising wood of locked portion and the lower edge of sticking department are arranged on the inclination edge that on terminal board column direction, square neck is oblique along with trend sticking department side down, also can access same effect.

In addition, in the first and second execution mode, pin connector and socket connector are made as circuit board electrical connector, and still, the kind of two connectors is not limited to this, for example, can be also the cable electric connector being connected with cable.
