In addition, cam part 64 possesses: become rotation bearing plane (rotation receiving portion) 64c of rotating fulcrum (pivot point) when making bar 60 rotate to opening and closing direction with bottom surface 37d (bottom wall part of the bar installation portion 35) sliding contact of longitudinal wall part 37; By rotation and the contact 40 of bar 60 and keep the bearing surface of cam surface 47a, 57a sliding contact of the spring 47,57 of terminal 50 (contact bearing surface and keep terminal bearing surface) 64d.

And then, cam part 64 possesses: the first surface 64e abutted with the bottom surface 37d (bottom wall part of bar installation portion 35) of longitudinal wall part 37 when bar 60 is full open position; Second 64f abutted with the bottom surface 37d (bottom wall part of bar installation portion 35) of longitudinal wall part 37 when bar 60 is buttoned-up status.In addition, first surface 64e and second 64f angulation θ (with reference to Fig. 7) is made to be acute angle.It should be noted that, in the present embodiment, first surface 64e and second 64f angulation θ is set as about 77 degree.In addition, be provided with the rotation bearing plane 64c of above-mentioned cam part 64 between first surface 64e and second 64f, this rotation bearing plane 64c is formed as the little arc surface of radius of curvature.Further, in the present embodiment, the radius of curvature of rotating bearing plane 64c is set as about 0.05mm.

In addition, in the present embodiment, as shown in Figure 6, cam part 64 is that laterally (fore-and-aft direction X) is elongated when bar 60 is in an open position, and the size of its above-below direction Z is less than the interval of the spring 47 of contact 40 and the interval of onto 45 and spring 57 and supporting arm 55.That is, when bar 60 is in an open position, cam part 64 and spring 47,57 are in contactless state.

In addition, when making bar 60 rotate to closing direction (the arrow A direction of Fig. 7), in the midway that cam part 64 is rotated in an upright manner, the size of the above-below direction Z of cam part 64 become than spring 47 and the interval of onto 45 and the interval of spring 57 and supporting arm 55 large.

That is, when bar 60 rotates to closing direction, along with the rotation of this bar 60, cam part 64 is rotated for rotating fulcrum to rotate bearing plane 64c.Further, in the midway that bar 60 rotates to closing direction, bearing surface 64d abuts with cam surface 47a, 57a of spring 47,57, and with cam surface 47a, 57a sliding contact.And then, when bar 60 rotates to closing direction, cam part 64 is rotated while bearing surface 64d and cam surface 47a, 57a sliding contact, makes spring 47,57 flexibly deflection deformation in the mode making the interval of the interval of the front end of the front end of spring 47 and onto 45 and spring 57 and supporting arm 55 relatively open.Then, along with the deflection deformation of spring 47,57, link spring 43,53 also elastic springing, the mode flexibly deflection deformation that diminishes with the interval of the fixation side contact site 44 of the drawer at movable side contact site 46 and fixation side contact part 41 that make drawer at movable side contact part 42 of contact 40 thus, keeps the mode flexibly deflection deformation that terminal 50 diminishes with the interval of the fixation side keeping arm 54 of the drawer at movable side keeping arm 56 and fixation side maintaining part 51 that make drawer at movable side maintaining part 52.Thus, drawer at movable side contact portion 46a moves to 44a direction, fixed side contact portion, and drawer at movable side contact portion 46a and fixed side contact portion 44a crimps with cable 2, and cable 2 is connected with contact 40 conducting in this condition.In addition, drawer at movable side engaging teat 56a moves to fixation side engaging teat 54a direction, and cable 2 is kept by maintenance terminal 50.Like this, cam part 64 is applied for the pressing force that this contact 40 is crimped to cable 2 to contact 40, and to the pressing force keeping terminal 50 to be applied for keeping cable 2.

And in the present embodiment, when making bar 60 rotate from open position to off-position, before midway, the height of cam part 64 uprises gradually, but when exceeding the amount of spin of regulation, the height step-down gradually of cam part 64.In addition, the midway to the action direction of the moment that bar 60 acts on turns to off-position at bar 60 from open position is made to change from opening direction to closing direction by utilizing the elastic-restoring force of spring 47,57 to press cam part 64.

Like this, in the midway that bar 60 rotates, by reducing the radius of turn of cam part 64 or making the action direction of the moment acting on bar 60 change to closing direction from opening direction, thus bring thump sense when action bars 60.

And then, as mentioned above, in the present embodiment, form rotation bearing plane (rotation receiving portion) 64c of cam part 64 as follows, that is, the first surface 64e abutted with the bottom surface 37d (bottom wall part of bar installation portion 35) of longitudinal wall part 37 under bar 60 open mode is acute angle with second the 64f angulation θ abutted with the bottom surface 37d (bottom wall part of bar installation portion 35) of longitudinal wall part 37 under bar 60 closed condition.Therefore, it is possible to make cam part 64 width narrower, bar 60 can be made easily to rotate.Like this, easily rotate by making bar 60, when making the action direction of the moment acting on bar 60 become closing direction from opening direction when the amount of spin exceeding regulation, bar 60 can be made more promptly to rotate to closing direction than ever, thus correspondingly can strengthen thump the sense of bar operation.

In addition, by the convex structure that bearing plane (rotation bearing plane) 64c is formed as first surface 64e and second 64f to combine will be rotated, bar operation can be carried out more swimmingly, and can suppress to be ground because bar operation causes rotating bearing plane (rotation bearing plane) 64c.

In addition, same thump sense can also be provided when rotating from closing direction to opening direction.

In addition, in the present embodiment, as shown in Fig. 6 and Figure 11, the rounded portions 64a of cam part 64 is formed and engages engaging recessed part (the jog mutually engaged) 64g that teat 47d, 57d engage.This engaging recessed part 64g is formed by the side 64h that can abut with front end face 47b, 57b of engaging teat 47d, 57d, the arc surface 64i that can abut with horizontal plane 47c, the 57c engaging teat 47d, 57d.In addition, to abut and horizontal plane 47c, 57c abut with arc surface 64i by making front end face 47b, 57b with side 64h, engaging teat 47d, 57d engage with engaging recessed part 64g (reference Figure 12).

That is, in the present embodiment, front end face 47b, 57b limit rod 60 movement forwards of engaging teat 47d, 57d, horizontal plane 47c, 57c limit rod 60 movement upward of engaging teat 47d, 57d.It should be noted that, also can be configured to front end face 47b, 57b are contacted with the mutual face of arc surface 64i with side 64h and horizontal plane 47c, 57c.So, the engaging degree of engaging teat 47d, 57d and engaging recessed part 64g can be improved further.

In addition, in the present embodiment, spring 47,57 with cam part 64 is provided with the jog (engaging teat 47d, 57d and engaging recessed part 64g) mutually engage, but this engaging teat 47d, 57d and engaging recessed part 64g are configured to be engaged by the opening and closing operations of common bar 60 (reference Fig. 6).

In addition, when bar 60 is in opening and closing operations or non-working condition (not inserting the state of cable 2) etc., when the bar 60 being in open mode being applied to load forwards, bar 60 stay open state ground forwards and be moved upward (bar 60 is to the direction relative movement departed from from contact 40) and cross jut 45b, 55b of roughly chevron time, engaging teat 47d, 57d are engaged with engaging recessed part 64g, thus suppresses bar 60 to depart from (with reference to Figure 11 and Figure 12) from housing 30.

Like this, not under the state engaged, suppress bar 60 to depart from from housing 30, but be configured to engage when bar 60 is subject to excessive loads and has carried out relative movement to off-direction, thus, the disengaging improving bar 60 stops the reliability of effect, and on this basis, owing to being not only simple locking but utilizing jog (engaging teat 47d and engaging recessed part 64g) to make to engage with each other, thus bar 60 can be suppressed further to depart from from housing 30.

In addition, when being applied with load forwards to the bar 60 of open mode, by the front end face 47b of engaging protrusion 47d and side 64h limit rod 60 movement forwards of engaging recessed part 64g, and by horizontal plane 47c and the movement upward of arc surface 64i limit rod, the disengaging improving bar 60 thus further stops effect.

In the following way the bar 60 of this structure is installed on housing 30.

First, make the front end of spring 47,57 through the through hole 63 of bar 60, and between the front end and the front end of onto 45 of spring 47 and front end and the front end of supporting arm 55 of spring 57, namely insert cam part 64 between horizontal plane 47c and jut 45b and between horizontal plane 57c and jut 55b.

Then, the supporting pivot 61 at the Width Y two ends of bar 60 is placed on the bearing portion 35a at the Width Y two ends of housing 30, and be installed to by maintenance metalwork 70 and link wall portion 34f, thus, bar 60 can be installed to the bar installation portion 35 of housing 30 in opening and closing mode freely.

In addition, in the present embodiment, when bar 60 is in an open position, cam part 64 transversely (fore-and-aft direction X) is formed long, thus when the front end of spring 47,57 is through through hole 63, that is, when the state that through hole 63 is opposed with the front end of spring 47,57, cam part 64 with horizontal plane 47c, 57c and less thick opposed between jut 45b, 55b.Therefore, when from horizontal plane 47c, 57c and when inserting cam part 64 between jut 45b, 55b, without the need to being pressed into larger power, thus cam part 64 can easily be inserted.

Next, the contact 40 when according to Fig. 6 to Figure 10 pole shutoff 60 being described and keep the action of terminal 50.

First, as shown in Figure 6, when bar 60 is positioned at open position, the top wall portion 32 of the spring 47 of drawer at movable side contact part 42 and housing 30 close to but do not contact with top wall portion 32.That is, there is gap with top wall portion 32 and become the state be separated in the spring 47 of drawer at movable side contact part 42.Now, the cam part 64 of bar 60 becomes non-engagement state with the cam surface 47a of spring 47.In addition, although the diagram of eliminating, the spring 57 of drawer at movable side maintaining part 52 also becomes same state.That is, there is gap with top wall portion 32 and become the state be separated in the spring 57 of drawer at movable side maintaining part 52, and the cam part 64 of bar 60 becomes non-engagement state with the cam surface 57a of spring 57.

Subsequently, cable 2 is inserted in housing 30.Now, because the thickness of the distance D2 between fixed side contact portion (front end) 44a of the fixation side contact site 44 of contact 40 and drawer at movable side contact portion (front end) 46a of drawer at movable side contact site 46 and cable 2 is roughly equal, so can suppress to produce frictional force between cable 2 and contact 40, thus can swimmingly cable 2 be inserted in housing 30.In addition, the fixation side of terminal 50 engaging teat 54a is kept to engage distance (distance engaged between teat for a pair) D1 of teat 56a with drawer at movable side less than the thickness of cable 2, therefore, when being inserted in housing 30 by cable 2, fixation side engaging teat 54a and drawer at movable side engage teat 56a thus the table back side of cable 2 is inserted in retaining hole 2c.Thus, cable 2 is kept by maintenance terminal 50 temporarily.It should be noted that, in the present embodiment, terminal 50 is kept by respectively arranging one at the Width Y two ends of contact 40, can do one's utmost to suppress in cable 2 and the increase keeping the frictional force produced between terminal 50, can do one's utmost to suppress to keep terminal 50 to hinder cable 2 to insert in housing 30 swimmingly.

In addition, under the state that cable 2 is inserted in housing 30, when to clockwise direction dwang 60 shown in arrow A, as shown in Figure 7, contact bearing surface 64d abuts with the cam surface 47a of spring 47, and with cam surface 47a sliding contact.And then, when to closing direction dwang 60, cam part 64 is rotated while making cam surface 47a and terminal bearing surface 64d sliding contact, and makes spring 47 flexibly deflection deformation in the mode that the interval of the front end of the front end and onto 45 that make the spring 47 of contact 40 is relatively opened.And in the midway that bar 60 rotates to closing direction, the roughly pars intermedia of spring 47 contacts with top wall portion 32.In addition, also carry out same action at maintenance terminal 50, in the midway that bar 60 rotates to closing direction, the roughly pars intermedia of the spring 57 after deflection deformation contacts with top wall portion 32.

In addition, along with the deflection deformation of spring 47, spring 43 flexibly deflection deformation is linked.Like this, bend by making spring 47 and linking spring 43, the mode flexibly deflection deformation that contact 40 diminishes with the interval of the fixation side contact site 44 of the drawer at movable side contact site 46 and fixation side contact part 41 that make drawer at movable side contact part 42 (distance of drawer at movable side contact portion 46a and fixed side contact portion 44a).That is, drawer at movable side contact portion 46a moves to 44a direction, fixed side contact portion.Consequently, cable 2 is connected with contact 40 conducting under the state crimped by drawer at movable side contact portion 46a and fixed side contact portion 44a.

Now, as shown in Figure 10, in maintenance terminal 50, when spring 57 and link spring 53 bend time, flexibly carry out deflection deformation in the mode that the interval of the fixation side keeping arm 54 of the drawer at movable side keeping arm 56 of drawer at movable side maintaining part 52 and fixation side maintaining part 51 (drawer at movable side engages teat 56a to engage teat 5a distance D1 with fixation side) diminishes.Consequently, drawer at movable side engaging teat 56a and fixation side engaging teat 54a becomes the state inserting retaining hole 2c from the table rear side of cable 2 further.That is, drawer at movable side engaging teat 56a and fixation side engaging teat 54a is increased further with the engaging degree of retaining hole 2c, thus keeps terminal 50 reliably to keep cable 2.

Like this, in the present embodiment, keep the shape of terminal 50 to be formed as roughly the same with the shape of contact 40, by the rotation of bar 60, distance (distance between a pair engaging teat) D1 between drawer at movable side engaging teat 56a and fixation side engaging teat 54a changes.That is, by the rotation of bar 60, the engaging of drawer at movable side engaging teat 56a and fixation side engaging teat 54a to retaining hole 2c is carried out.

In addition, in the present embodiment, when make bar 60 to closing direction rotate and make the entirety of spring 47,57 towards top wall portion 32 direction flexure time, in the midway that bar 60 rotates to closing direction, the roughly pars intermedia of spring 47,57 contacts with top wall portion 32.

It should be noted that, as shown in figure 13, when make bar 60 to closing direction rotate and make the entirety of spring 47 towards top wall portion 32 direction flexure time, if spring 47 does not contact with top wall portion 32, the stress then produced because of the flexure of spring 47 and drawer at movable side contact site 46 is concentrated to link spring 43, thus link spring 43 may be tired.And be also same in maintenance terminal 50, linking spring 53 also may be tired.

But, as in the present embodiment, in the midway that bar 60 rotates to closing direction, contact with top wall portion 32 by making the roughly pars intermedia of spring 47, when drawer at movable side contact part 42 bends, stress the concentrating with the contact site of top wall portion (housing 30 inwall) 32 also to spring 47 produced because contact 40 bends can be made.Consequently, can make to act on the stress dispersion linking spring 43, reduce the stress raisers to the link spring 43 linking drawer at movable side contact part 42 and fixation side contact part 41, thus it is tired to suppress to link spring 43.

In addition, in the midway that bar 60 rotates to closing direction, contact with top wall portion 32 by making the roughly pars intermedia of spring 57, when drawer at movable side maintaining part 52 bends, stress the concentrating with the contact site of top wall portion (housing 30 inwall) 32 also to spring 57 produced because keeping the flexure of terminal 50 can be made.Consequently, can making to act on the stress dispersion linking spring 53, reducing link spring 53 stress raisers to linking drawer at movable side maintaining part 52 and fixation side maintaining part 51, thus it is tired to suppress to link spring 53.

In addition, when bar 60 rotates to closing direction further, under the state that the roughly middle part in keep-spring portion 47,57 contacts with top wall portion 32, bar 60 turns to off-position.That is, in the present embodiment, rotate to closing direction at bar 60, under the state that drawer at movable side contact portion 46a and fixed side contact portion 44a crimps with cable 2, the roughly pars intermedia of spring 47 contacts with top wall portion 32 (with reference to Fig. 8).In addition, although the diagram of eliminating, keep terminal 50 also same with contact part 40, under the state that bar 60 keeps terminal 50 to keep cable 2 to closing direction rotation, the roughly pars intermedia of spring 57 contacts with top wall portion 32.

Therefore, even if when using connector 1 (when bar 60 turns to off-position and makes contact 40 and keep terminal 50 to crimp with cable 2), can disperse, so the life of product of connector 1 can be improved owing to acting on the stress linking spring 43,53.

And then in the present embodiment, as shown in Figures 7 and 8, the root side near stage portion 47e, the 57e of roughly pars intermedia setting of spring 47,57 contacts with top wall portion 32.(contact 40 has been shown in Fig. 7 and Fig. 8, but has kept terminal 50 to be also same structure).That is, after spring 47,57 contacts top wall portion 32, the part deflection deformation upward of the thinner thickness of side more forward than stage portion 47e, 57e.

Like this, by making spring 47,57 bend with stage portion 47e, 57e for basic point, stress can be efficiently made to concentrate to spring 47,57.Therefore, it is possible to it is tired to suppress to link spring 43,53 further.

As mentioned above, in the present embodiment, cable 2 arranges retaining hole 2c, and be provided with on housing 30 and keep terminal 50, the drawer at movable side that this maintenance terminal 50 has the table back side insertion from cable 2 and carries out engaging engages teat 56a and fixation side engaging teat 54a (a pair engaging teat).Therefore, the drawer at movable side of terminal 50 engaging teat 56a and fixation side engaging teat 54a (a pair engaging teat) is kept to insert the retaining hole 2c of cable 2 from the table back side and engage.Therefore, even if at the uneven thickness of cable 2 or External Force Acting in cable 2, cable 2 also can be made to be not easy to extract.That is, according to the present embodiment, cable 2 can be suppressed to depart from from connector 1.

In addition, in the present embodiment, keep the shape of terminal 50 to be formed as roughly the same with the shape of contact 40, utilize the rotation of bar 60, distance (distance between a pair engaging teat) D1 between drawer at movable side engaging teat 56a and fixation side engaging teat 54a changes.That is, utilize the rotation of bar 60, carry out the engaging of drawer at movable side engaging teat 56a and fixation side engaging teat 54a to retaining hole 2c.Therefore, carry out dividually in addition keeping terminal 50 to keep the operation of cable 2 for passing through without the need to being connected with the conducting of contact 40, thus realize the raising of the operability of connector 1.

In addition, be set in the present embodiment, at least when bar 60 is in an open position, the fixation side of terminal 50 engaging teat 54a is kept to engage the distance D1 of teat 56a with drawer at movable side shorter than the distance D2 between fixed side contact portion (front end) 44a of the fixation side contact site 44 of contact 40 and drawer at movable side contact portion (front end) 46a of drawer at movable side contact site 46.Therefore, when keeping the link spring 53 of terminal 50 and the link spring 43 of contact 40 to bend respectively, can the drawer at movable side of maintenance terminal 50 be made to engage teat 56a before the drawer at movable side contact portion 46a of contact 40 contacts with conductor 2b and engage with retaining hole 2c.Therefore, when the drawer at movable side contact portion 46a of contact 40 contacts with conductor 2b, can more reliably suppress cable 2 to misplace.

In addition, in the present embodiment, the distance D1 of the fixation side of terminal 50 engaging teat 54a and drawer at movable side engaging teat 56a is kept to be set as less than the thickness of cable 2.In addition, when cable 2 is inserted in housing 30, fixation side engaging teat 54a and drawer at movable side engaging teat 56a (a pair engaging teat) is inserted in retaining hole 2c from the table back side of cable 2, thus cable 2 is kept terminal 50 keeps temporarily.Therefore, even if under the state that bar 60 is in an open position, cable 2 also can be suppressed to depart from, so can reliably suppress cable 2 to misplace further when bar 60 carries out opening and closing operations.

Above, suitable execution mode of the present invention is illustrated, but the invention is not restricted to above-mentioned execution mode, can various distortion be carried out.

Such as, maintenance terminal also can be made to link with other control members being different from bar, utilize other operations being different from the operation of bar that maintenance terminal is engaged with retaining hole.

In addition, keep the shape of terminal to be not limited to the shape gone out illustrated in above-mentioned execution mode, it can be formed as various shape.

In addition, also can change the specification (shape, size, layout etc.) of housing, bar, cam part, other details.
