On horizontal (end) surface of housing main body 11, the position of bolster 27 on the vertical axis substantially the same with bolster 25 is outstanding, this bolster 27 engages with the bearing portions 46A of the attitude updating arm 46 of lever 40, to be preferably in two position supporting levers 40 cooperating with bolster 25.(be preferably on the relative direction basically outstanding) one or more maintenance projection 27A are formed near the guiding end place of bolster 27 or its, thereby attitude updating arm 46 can not leave bolster 27 during the rotation of lever 40 is moved.One or more, preferably a pair of laterally (left side and right) regulates (preferably relative basically) width end that projection 28 is formed on the basal surface 11BS of housing main body 11, and this width end is positioned at the place, side of the retainer installing hole 17 relative with bolster 27 basically with respect to forward and backward directions FBD.(best two) regulate projection 28 and preferably give prominence to identical distances with bolster 27 basically, thereby its guiding end is aimed at the guiding end of bolster 27 basically, thereby preventing that female connector housing 10 from connecting in connecting the process of two connector shells 10,80 turns forward simultaneously.

As shown in accompanying drawing 20, cam pin inserts groove and is preferably in the position that is arranged in bolster 25 fronts with respect to forward and backward directions FBD and is formed on covering wall 22, this cam pin insertion groove extends on forward and backward directions FBD basically and forms opening at front end, and the cam pin 88 of positive connector shell 80 passes this opening and inserts.And, direction recess 22B is preferably in towards the position that cam pin insertion groove 22A opposite side is removed and is formed in the covering wall 22, this direction recess extends on forward and backward directions FBD equally basically, and at front end formation opening, the locking projection 89 of positive connector shell 80 inserts along this opening to small part.Cam pin 88 inserts, basically keep inserting (preferably relative basically) transverse edge sliding contact of groove 22A simultaneously with cam pin, and locking projection 89 inserts, and keeps basically (preferably relative basically) the transverse edge sliding contact with direction recess 22B simultaneously.And, direction recess 22E is formed in the covering wall 22, basically parallel with the cam pin insertion groove 22A that is positioned at direction recess 22B opposite side place with direction recess 22B, the projection 92 that is disengaged of positive connector shell 80 is inserted maintenance sliding contact with it basically simultaneously along this direction recess.

Lever installation surface 23 and the excision of covering wall 22 the pick ofs; locate a side (being the left side in the example shown) of spatial accommodation 21 with the rear surface that exposes housing main body 11; and the effect of protection part spatial accommodation 21A is played in the space of this exposure, is used for holding to small part the protection part 48 of the lever 40 that preferably is in the rectangular frame form basically.And, step part 29 is formed in the side surface of housing main body 11, as shown in accompanying drawing 21, this step part perpendicular extend and/or basically in the face of its laterally (on) spatial accommodation 21 at side place, and these step part 29 region in front play the effect than step recess 29B shown in the lower slightly accompanying drawing 7 of back region.Basically play the effect of contact surface 29A towards the ledge surface of preceding step part 29, this contact surface is subjected to the motion arm 49 of lever 40 and pushes when lever 40 rotates or is turned back to connection termination position CEP.

As shown in accompanying drawing 18, lever 40 preferably includes (at least one) lobe plate 47, and attitude updating arm 46 and motion arm 49 preferably are in a shape basically on the whole thereby this motion arm preferably connects the end or the end portion of lobe plate 47 and arm 46.As shown in accompanying drawing 7, the cam groove 41 that can engage with the cam pin 88 of positive connector shell 80 is on specific (that preset or predeterminable) direction in the end portion with motion arm 49 isolated lobe plates 47 and extends, and along the relatively moving of cam groove 41, two connector shells 10,80 can connect and separate by cam pin 88.Should be noted in the discussion above that this cam groove 41 preferably is not formed in the attitude updating arm 46.Below in the description to the structure of lever 40, be positioned at about forward and backward directions FBD with reference to lever 40 and be positioned at the state (state shown in the accompanying drawing 10) that connects terminal position CEP place.

The inner surface of lobe plate 47 (lower surface) cuts at the inner end positions place near cam groove 41, form (preferably circular basically) bearing portions 47A.Be in basically and the engagement recesses 47B of the arc form that this bearing portions 47A is concentric is formed near this bearing portions 47A position, and lobe plate bonding part 26 basically with this engagement recesses 47B sliding contact, lead the rotation of lever 40 is moved or turned round move.

Interim keeping arm 51 is formed on the position of the neighboring of lobe plate 47 near the inlet of cam groove 41, this interim keeping arm elastically deformable and preferably extending on forward and backward directions FBD basically when lever 40 is in CEP place, connection termination position.Before two connector shells 10,80 connected, the most advanced and sophisticated projection 51A of interim keeping arm 51 engaged with the interim holding portion 31 at the transverse edge place of the spatial accommodation 21 that is arranged on housing main body 11, thereby prevented moving or rotating of lever 40.When the attended operation of two connector shells 10,80 begins, or just begun soon, the projection 92 that is disengaged that most advanced and sophisticated projection 51 is subjected to positive connector shell 80 promotes, and with strain on the direction that unlocks, thereby allows lever 40 to rotate.

The end (the preferably side of motion arm 49) that can be formed on lobe plate 47 with the locking piece 42 of locking projection 89 resilient engagement of positive connector shell 80 is located, this end basically with set terminal relative of cam groove 41 and bearing portions 47A.Locking piece 42 preferably defines between a pair of slit 42A, this slit forms opening and basically at the Width of lobe plate 47 in the rear end of lobe plate 47, be that forward and backward directions FBD go up to extend, and can its front end as terminal laterally (basically up and down) strain in basis.One of these two slit 42A are positioned near the sloping edge part 47E that forms by a turning of excising lobe plate 47, and can't extend forward again.

In outer surface (upper surface) zone of the lobe plate 47 of locking piece 42 fronts, form and withdraw from part 52, this withdraws from part and is in the recess form, lever 40 is used to avoid disturb locking projection 89, so that can be moved further or rotate the mobile of lever 40 or during rotating.Locking projection 53 is formed on the basic end of this locking piece 42, and this locking projection is continuous with the rear end of withdrawing from part 52 basically by a step (step).The front surface that forms the locking projection 53 of above-mentioned step outwards be formed into (on) in the 53A of the oriented of rear-inclined surface, as shown in accompanying drawing 1, and the upper surface of locking projection 53 forms flat basically surface in surperficial equal height of reference basically or radial position place with lobe plate 47 basically.And the rear surface of locking projection 53 forms locking surface 53B, and the best perpendicular of this locking surface (or perpendicular to forward and backward directions FBD and/or closure CD) forms step with the recess 54 that is formed on locking projection 53 back.During the rotation of lever 40, locking projection 89 moves on the locking projection 53 along the guide surface 53A of locking projection 53, thereby makes the inside basically or downward strain of locking piece 42.When lever 40 locking projection 89 basically with the plane surface sliding contact of locking projection 53 after when arriving connection termination position CEP basically, locking projection 89 to small part is installed in the recess 54, and by the locking surface 53B of locking projection 53 locking, thereby can not deviate from.

Locking piece operation part 55 is arranged on the higher slightly position of rear end of locking piece 42.By inwardly or downwards pushing this part 55, locking piece 42 can be disengaged from locking projection 89.Protection part 48 (preferably being in the rectangular frame form basically) is formed near the rear end of lobe plate 47 or its; thereby to small part; preferably basically fully around the circumference of locking piece operation part 55, this locking piece operation part can protect the built-in function of part 48 to become to be disengaged locking piece 42 by this.This protection part 48 makes the one side combine with motion arm 49; laterally or vertically protrude with rear end from lobe plate 47; and when lever 40 was in CEP place, connection termination position, this protection part (preferably whole basically) was received among the protection part spatial accommodation 21A of housing main body 11.

And as shown in accompanying drawing 1 and 24, pressing part 44 transverse edge terminal along the basis of locking piece 42 gone up outstanding at the inner surface (lower surface) of lobe plate 47.When locking piece 42 since locking projection 89 and locking projection 53 before the CEP of the connection termination position of lever 40 or near the joint at rotation final position place and when inside or downward strain, but pressing part 44 preferably contacts with the pressing part 66 of second spring section 63 of surveying terminal 60 basically from behind basically, thereby second spring section 63 is with first spring section, 62 downward or inside strains.In the while basically of lever 40 arrival connection termination position CEP, pressing part 44 preferably stops to push second spring section 63, so that small part elastic return second spring section 63 and first spring section 62.The front end perpendicular of pressing part 44 (or perpendicular to forward and backward directions FBD and/or closure CD) is erect, and its bottom end is for making progress or outside slope towards rear-inclined.When locking piece 42 maximum flexibilities were out of shape, this slope of pressing part 44 kept substantial horizontal.

On the inner surface of lobe plate 47, the pre-pressing part 45 that separates with pressing part 44 is formed on locking piece 42 fronts and is outstanding from the position that pressing part 44 moves inward slightly on Width.Be similar to pressing part 44, pre-pressing part 45 extends on forward and backward directions FBD, and is preferably in and has the size shorter than pressing part 44 on the forward and backward directions FBD.During the rotation of lever 40, but pressing part 44 is pushed before the pressing part 66 of surveying terminal 60, but this pre-pressing part 45 contacts (preferably basically from behind) basically with pressing part 66, so that second spring section 63 and first spring section, 62 strains.Along with lever 40 is moved further or operates or rotates or turn round, but this pre-pressing part 45 moves past pressing part 66.When this pre-pressing part 45 stops to push second spring section 63, but pressing part 44 is pushed the pressing part 66 of second spring section 63, rather than pre-pressing part 45.Downward slope towards rear-inclined is formed on the bottom of the front end of pre-pressing part 45, and its bottom is preferably formed as substantially horizontal plane surface (perhaps being arranged essentially parallel to the surface of forward and backward directions FBD and/or closure CD).Because pre-pressing part 45 is formed in the scope that the strain that is not subjected to locking piece 42 influences, and spaced apart with pressing part 44, so can avoid the interference of the front end of the rear end of pre-pressing part 45 and pressing part 44, locking piece 42 is subjected to strain simultaneously.

Herein, along with operation (rotating or revolution) lever 40, contact terminal 98 to small part enters surveys terminal 60.Yet, because during the rotation of lever 40, first spring section 62 is subjected to pre-pressing part 45 with second spring section 63 and pushes, being subjected to pressing part 44 then pushes, to reduce the contact portion of first spring section 62, so the contact portion 65 of the contact terminal 98 and first spring section 62 keeps not contacting with each other.On the other hand, when lever 40 arrives contact final position CEP basically, pressing part 44 stops to push second spring section 63, make second spring section 63 with first spring section 62 to the small part elastic return, so that the contact portion 65 of the contact terminal 98 and first spring section 62 contacts, thus closed detection circuit.

As shown in accompanying drawing 13, the motion arm 49 of lever 40 preferably is in the form of the long slab of short transverse extension basically.When lever 40 arrives connection termination position CEP basically, this motion arm 49 to small part is installed among the step recess 29B of housing main body 11, and its front end is being pressed against on the short transverse on the contact surface 29A of housing main body 11 basically, thereby promptly on closure CD, push with contact surface 29A forward.The front end of motion arm 49 plays the effect that promotes surperficial 49A, connects with the attitude that tilts to prevent two connector shells 10,80.

As shown in accompanying drawing 24, the attitude updating arm 46 of lever 40 is arranged on basically the position in the face of lobe plate 47, make housing main body 11 to small part between them, and have the width shorter, thereby avoid interference retainer 90 than lobe plate 47.In the position coaxial with the bearing portions 47A of lobe plate 47 basically with respect to vertical direction VD, bearing portions 46A penetrates attitude updating arm 46 on thickness direction.One or morely withdraw from the inside edge that groove 46B and one or more trip edge 46E are formed on the bearing portions 46A of attitude updating arm 46, one or more maintenance projection 27A are installed to this to small part and withdraw from the groove, and this trip edge can engage with keeping projection 27A on the detaching direction of lever 40.

Hook portion 43 is formed on the guiding end (away from the end of motion arm 49) of attitude updating arm 46 and locates, this hook portion has and is becoming to be not equal to 0 or 180 angle with the rotation direction of lever 40, preferably vertical with it basically side upwardly extending hook-type surface 43A.Connect simultaneously at two connector shells 10,80 under the situation about tilting from their correct attitude with respect to Width WD, before lever 40 arrives connection termination position CEP, hook portion 43 engages with the holding portion 91 of positive connector shell 80, makes its hook-type surface 43A relative with the rear surface of holding portion 91 basically.And, arriving in the process of connection termination position CEP at lever 40, hook portion 43 promotes or actuates the attitude that holding portion 91 is proofreaied and correct two connector shells 10,80 that connecting basically.

Connecting CSP place, starting position, by motion arm 49 is located lean on more than the rear surface of housing main body 11 after, lever 40 preferably is arranged so that from the rear surface of housing main body 11 outstanding, as shown in accompanying drawing 7 and 20, and at CEP place, connection termination position, the rear end surface of lever 40 preferably flushes with the rear surface of housing main body 11 basically, preferably not form step with the rear end surface of housing main body 11, as shown in accompanying drawing 10 and 16.Therefore, whether flush each other basically at CEP place, connection termination position, can judge whether two connector shells 10,80 correctly connect by the rear end surface of confirming lever 40 and housing main body 11.

Next, the function of present embodiment is described.At first, positive connector shell 80 is fixed on the outer surface of electric device or electronic installation (as circuit board, terminal box, electric or electronic apparatus or device etc.), between the conductive path of male terminal joint 99 and electric device or electronic installation, set up simultaneously and be electrically connected, and keep waiting for, till the attended operation with female connector housing 10 begins.

On the other hand, in female connector housing 10, retainer 93 preferably is inserted in the retainer installing hole 17 of shell to small part, and remains on part latched position (primary importance or holding fix) and locate.Under this state, lobe plate 47 to the small part of lever 40 slides in the spatial accommodation 21 of housing main body 11, and the bearing portions 47A of lobe plate 47 engages with bolster 25, the bearing portions 46A of the arm of attitude updating simultaneously 46 engages with bolster 27 at opposite side, thereby lever 40 is installed in the housing main body 11, preferably remains on CEP place, connection termination position simultaneously.At this moment, the attitude updating arm 46 of lever 40 and retainer 93 are in partly overlapping at least position relation on the thickness direction, have avoided its phase mutual interference but a part to the small part by attitude updating arm 46 enters into the recess 96 that withdraws from of retainer 93.

Subsequently, above-mentioned female connector housing 10 is transported to the assembling place of female terminal fitting 97.In the assembling place, one or more female terminal fittings 97 for example by craft or automaton from the inserting side, preferably be inserted in the cavity 12 of housing main body 11 to small part from behind basically.In the case, owing to do not have step between the rear end of the rear end of lever 40 and housing main body 11, so female terminal fitting 97 can insert smoothly.All after small part is inserted, push or be pushed into retainer 93 to complete latched position (second place or installation site), at all female terminal fittings 97 with (preferably dual) locking female terminal fitting 97 (preferably cooperating) with lock part 13.Owing to, make it not outstanding, allow the operation of lever 40 or move (for example, rotating) from housing main body 11 by retainer 93 is pushed to complete latched position.Should be noted in the discussion above that short circuit terminal 70 and survey terminal 60 and be assembled in the housing main body 11 with female terminal fitting 97 simultaneously.

Subsequently, as shown in accompanying drawing 7 and 20, lever 40 (preferably rotate or revolution) operation to or operate and connect CSP place, starting position, the most advanced and sophisticated projection 51A of interim keeping arm 51 preferably engages with the interim holding portion 31 of housing main body 11, and causes the entering basically of cam pin insertion groove 22A that enters with housing main body 11 of cam groove 41 to be communicated with on horizontal or vertical direction.Under this state, one or more corresponding female connector housing 10 are installed to two of recipient 81 of the positive connector shell 80 that remains on wait state slightly and install in the recesses 83.Then, as shown in accompanying drawing 8, each is disengaged projection 92 and all himself is inserted between interim keeping arm 51 and the interim holding portion 31, so that they are disengaged from each other, and cam pin 88 to small part enters cam pin and inserts groove 22A and cam groove 41, and locking projection 89 enters direction recess 22B.

When by keeping or when handling or operating motion arm 49 this state under and on arrow directions X shown in the accompanying drawing 8, operate (rotation or turn round) lever 40, in the operation of lever 40 (for example, rotate) starting stage, cam pin 88 inserts groove 22A along cam pin basically and moves, locking projection 89 moves along direction recess 22B, and short circuit cancellation part 87 to small part is pushed to self them between the elastic component 71 and female terminal fitting 97 of short circuit terminal 70, keep in touch with these elastic components 71, as shown in accompanying drawing 2, thus cancellation short circuit state.And, in the operation of lever 40 (for example, rotation) under the initial condition, but pre-pressing part 45 preferably contacts with the pressing part 66 of surveying terminal 60 basically from behind basically, but and preferably sliding on each other on the closure CD of two connector shells 10,80 basically in two slopes of this pre-pressing part 45 and pressing part 66, thereby strain second spring section 63.Because the front end of second spring section 63 tilts, so first spring section 62 is out of shape (being subjected to pushing basically) downwards or inwardly on deformation direction DD, thereby the height of the contact portion 65 of first spring section 62 becomes and is lower than the height of corresponding contact terminal 98, as shown in accompanying drawing 3.By this way, enter the commitment of surveying in the terminal 60 at contact terminal 98, first spring section 62 is out of shape (being subjected to pushing basically) downwards or inwardly on deformation direction DD, and contact terminal 98 to small part is inserted into the rear side of surveying terminal 60 and separates with contact portion 65 simultaneously.

Along with lever 40 is further operated (preferably rotating or revolution), the locking projection 53 of locking piece 42 moves on the locking projection 89, as shown in accompanying drawing 4, and locking piece 42 downward or inside strains, but make pre-pressing part 45 remove from pressing part 46, and but the front end of pressing part 44 is pressing part 66, rather than pre-pressing part 45, pushes downwards or inwardly.Because second spring section 63 keeps strain during this period, so under the situation of the height and position of the contact portion 65 of first spring section 62 that do not raise, the contact portion 65 of first spring section 62 and contact terminal 98 keep separately.As shown in accompanying drawing 5 and 9, pass through in the process of locking projection 89 at locking projection 53, but the slope of pressing part 44 slides on the pressing part 66 basically, while moves as arc along the rotation path of lever 40 basically, thereby second spring section 63 and first spring section 62 keep strains (on deformation direction DD).

When lever 40 arrives CEP place, connection termination position basically, when making the locking projection 53 of locking piece 42 move past locking projection 89 basically, as shown in accompanying drawing 6, locking piece 42 is towards its initial natural recovering state or return to the initial natural state, and but pressing part 44 is removed from pressing part 66, push stopping basically, make second spring section 63 and first spring section 62 towards they the initial natural recovering state or return to the initial natural state.Then, the height and position of the contact portion 65 of first spring section 62 raises, and promoting contact terminal 98, and between them, set up and be electrically connected from following (on relative with deformation direction DD basically direction), thus closed detection circuit.By contact terminal 98 is carried out the electrical resistivity survey survey with the signal that is sent that is connected of surveying terminal 60, can know that lever 40 has arrived connection termination position CEP, and two connector shells 10,80 connect correctly.Certainly, be electrically connected, can construct particular electrical circuit by between the positive and female terminal fitting 99,97, setting up.

When lever 40 arrives CEP place, connection termination position basically; lobe plate 47 to small part is received in the spatial accommodation 21 of housing main body 11; protection part 48 to small part is received into protection part spatial accommodation 21A, and motion arm 49 to small part is installed among the step recess 29B of housing main body 11.Then, as shown in accompanying drawing 10 and 16, the rear end of the rear end of lever 40 and housing main body 11 preferably flushes basically each other, thereby eliminates step especially.By confirming this position relation, can know that also lever 40 arrives connection termination position CEP.

In the present embodiment, the center of rotation axis of lever 40 is preferably disposed on the position of removing from Width WD, and the engaging zones of cam groove 41 and cam pin 88 only is arranged in the lobe plate 47 of lever 40, as shown in accompanying drawing 12.So, the connection power of lever 40 with the central axis that rotates and the engaging zones mode effect of deflection mutually of cam groove 41 and cam pin 88, therefore there is a possibility, be that attended operation is carried out comparatively fast in this side, and postponed away from central axis and the side relative with the engaging zones of cam groove 41 and cam pin 88.

Yet, in the present embodiment, even two connector shells 10,80 all tilt from their correct connection attitude with respect to vertical direction VD, preferably basically before lever 40 will arrive connection termination position CEP, holding portion 91 is also hooked or engaged to the hook portion 43 of lever 40, and promote or spur it, as shown in accompanying drawing 15.What by this way, cause that the attended operation at the place, side of the attitude updating arm 46 that is easy to be postponed carries out is very fast.Therefore, when lever 40 arrived connection termination position CEP, the attitude of two connector shells 10,80 all was corrected into correct basically connection attitude.

And, even two connector shells 10,80 tilt from their correct basically connection attitudes with respect to Width WD, just before lever 40 arrives connection termination position CEP, the promotion surface 49A of the motion arm 49 of lever 40 also contacts with the contact surface 29A of housing main body 11 basically, and preferably push it against recipient 81, as shown in accompanying drawing 13.By this way, it is very fast that the attended operation away from the end of central axis that causes being easy to postpone is carried out.Therefore, when lever 40 arrived the connection termination position, the attitude of two connector shells 10,80 all was corrected to correct basically connection attitude.

When two connector shells 10,80 connect, locking projection 89 preferably moves and keeps direction recess 22B sliding contact with housing main body 11 simultaneously, and cam pin 88 is same moves and preferably keep simultaneously basically inserting groove 22A sliding contact with the cam pin of housing main body 11.When they moved, the attended operation of two connector shells 10,80 was led, thereby can prevent the inclination of the attitude of two connector shells 10,80.And, when lever 40 arrives connection termination position CEP, locking projection 89 location and/or be retained to small part between the locking projection 53 of the locking piece 42 of the rear end of the direction recess 22B of the cover part 22 of housing main body 11 and lever 40, as shown in accompanying drawing 14.So, under the lock-out state of lever 40, can know that two connector shells 10,80 are in their correct connection attitudes.

Usually, in lever-type connector, when operating (preferably rotating or revolution) lever 40, connector shell 10,80 is connected by the connection power (acting on the power on the direction that connects two connector shells 10,80) that acts between them by the cam pin 88 that engages with cam groove 41.Yet, especially in present embodiment,, be difficult to the above-mentioned connection power between two connector shells of balance 10,80 if 47 of lobe plates are arranged on the surface of female connector housing 10.In other words, lobe plate 47 set sides took the lead with being connected of positive connector shell 80, on the contrary, be not provided with the connection delay of the relative side of lobe plate 47, therefore two connector shells 10,80 can connect with the attitude that tilts with respect to the height central axis.And if the bonding station of cam pin 88 and cam groove 41 is removed with respect to the Width WD of two connector shells 10,80, then two connector shells 10,80 can connect with the attitude that tilts with respect to the width central axis.

In this, according to present embodiment, after finishing attended operation, except the bonding station of cam groove 41 and cam pin 88, provide another bonding station, thereby connection power is subjected to balance with respect to the Width and/or the short transverse of two connector shells 10,80.So the attitude of two connector shells 10,80 can be corrected to straight basically connection attitude.

More special is, even as top described, the lobe plate 47 set places, side that are connected of two connector shells 10,80 take the lead, when the attended operation of two connector shells 10,80 is finished, hook portion 43 by attitude updating arm 46 and holding portion 91 be at the joint with respect to the position of the height central axis substantial symmetry of two connector shells 10,80, also can be on the direction that connects two connector shells 10,80 generation power.So connection power acts on two opposite side places that connect the height central axis of shells 10,80 in the mode of balance basically, make to be connected to postpone side and carry out, and the attitude of two connector shells 10,80 all is corrected to straight basically connection attitude.

Because the bonding station of cam pin 88 and cam groove 41 preferably moves away to a side from the width central axis of two connector shells 10,80, comparatively fast is connected with positive connector shell 80 in this engage side in some cases so be provided with the female connector housing 10 of lever 40.Yet, after finishing attended operation, the promotion surface 49A of the motion arm 49 of lever 40 shifts female connector housing 10 in the positive connector shell 80 onto in relative with the bonding station of cam pin 88 and cam groove 41 basically width side, therefore if necessary, the attitude of two connector shells 10,80 can be corrected to straight basically connection attitude.

And, because the joint attitude of cam pin 88 and cam groove 41 preferably moves away to a side from the width central axis of two connector shells 10,80, can be connected with positive connector shell 80 quickly in this engage side in some cases so be provided with the female connector housing 10 of lever 40.Especially, because locking projection 89 is subjected to direction recess 22B guiding in the width side relative basically with above-mentioned bonding station, so when attended operation is finished, the connection attitude of female connector housing 10 remains on correct basically attitude, and locking piece 42 engages with the locking projection 89 of positive connector shell 80, two connector shells 10,80 are locked in their connection status.

Therefore, in order to proofread and correct the connection attitude of two connector shells, control member (as lever 40) is removable be installed on the female connector housing 10 but maybe can be operated (preferably rotationally or pivotally), and comprise at least one lobe plate 47 that is formed with at least one cam groove 41, and this lobe plate 47 preferably only is arranged on last or this surface, a surface (or position) of female connector housing 10.Bonding station except cam groove 41 and cam pin 88, by being set in place in hook-type or the bonding part 43 and the joint that is arranged on the holding portion 91 in the positive connector shell 80 at attitude updating arm 46 places of the position of facing the lobe plate 47 in the lever 40 basically, one position is arranged between lever 40 and the positive connector shell 80, to produce the power on the direction that two connector shells, 10,80 courts are spurred each other or promote basically.

And, as mentioned above, if the outstanding or indentation from the rear end surface of female connector housing 10 of the rear end surface of (as preferred movable member) lever 40 then for example may be difficult to female terminal fitting 97 is inserted in the cavity 12 by automaton.Yet, according to present embodiment,, make the rear end surface of lever 40 preferably keep flushing basically with the rear end surface of female connector housing 10 because lever 40 remains in the negative connector 10, insert operation so can carry out terminal by automaton smoothly.Certainly, also can more successfully insert the manual operation of clamped nipple.

Owing to flush basically with the rear end surface of female connector housing 10 and/or consecutive hours basically when the rear end surface of lever 40 becomes, lever 40 arrives connection termination position CEP, so by confirming the state that flushes basically of lever, just can detect that (for example, visually or by suitable detector) lever 40 has arrived connection termination position CEP and two connector shells 10,80 correctly connect.

And, because the attitude updating arm 46 of lever 40 is arranged on horizontal (end) surface of female connector housing 10, to cover the laterally at least a portion on (end) surface, and installation retainer, so retainer 93 and attitude updating arm 46 may be interfering with each other, hindering its displacement of locating in part latched position (primary importance), retainer 93 at this part latched position place the outer surface from female connector housing 10 outstanding.Yet, because according to present embodiment, the displacement of retainer 93 and lever 40 is used for when retainer 93 is positioned at part latched position (primary importance), avoiding the promotion surface 93A that recess 96 is formed on retainer 93 that withdraws from that retainer 93 and lever 40 interfere with each other, so can not hindered.

And, because unless retainer 93 is positioned at complete latched position (second place), otherwise preferably the operation of the contact preventing lever 40 by attitude keeping arm 46 and retainer 93 move or displacement (for example, rotate), if stoped so can detect the rotation of lever 40, then retainer 93 rests on the centre position by being subjected to inadequate promotion, does not arrive complete latched position (second place).

Therefore, in order (for example to insert operation by carrying out clamped nipple smoothly, by automaton or manually) improve the operability of connector, one or more terminal insertion holes are formed in the rear end surface of female connector housing 10, and one or more female terminal fittings 97 were preferably inserted this terminal insertion hole basically from behind.Formation by the lever 40 (as preferred movable member) of cam groove 41 operationally (preferably rotationally or pivotally) be installed on the female connector housing 10.This lever 40 remains in the female connector housing 10, makes the rear end surface of lever 40 keep flushing basically with the rear end surface of female connector housing 10.Therefore, owing between the rear end surface of the rear end surface of female connector housing 10 and lever 40, do not have out-of-flatness, insert operation (for example, passing through automaton) so can carry out terminal smoothly.
