As shown in Figure 11 etc., the upper surface at female connector housing 27 is provided with for by negative and positive The lock arm 33 that connector shell 1,27 locks under chimerism.Lock arm 33 connects from the moon The front end of device housing 27 is that single armed beam-like extends formation towards rear, it is possible to leading section as fulcrum Flexural deformation downwards.The prominent formation of upper surface at the central part of the length direction of lock arm 33 There is locking projection 34.In the side that lock arm 33 rearward extends with the both sides from locking projection 34 Formula is continuous with a pair connecting portion 35.The rear end of two connecting portions 35 is exceeding the shape of one-level each other It is formed by connecting under state as releasing operating portion 36.Correctly it is fitted together at male and female connectors housing 1,27 Under state, locking projection 34 is locking with the locking teat 7 in cover portion 3, thus, and the connection of negative and positive Device housing 1,27 is locked under chimerism each other.

As shown in Figure 12 etc., at the upper surface of female connector housing 27, to press from both sides in the width direction Hold the mode of lock arm 33 to erect and arrange pair of locking arm protective bulkhead 37.Two lock arms are protected Retaining wall 37 prolongs towards rear along the longitudinal direction from the leading section of the upper surface of female connector housing 27 Stretching, the back-end location that the position of its rear end reaches than releasing operating portion 36 is slightly closer to anterior position. In the side-looking visual angle of female connector housing 27, lock arm protective bulkhead 37 is formed as only locking Projection 34 conciliates the height (with reference to Figure 13) that division operation portion 36 highlights upward.

At the upper surface of female connector housing 27, erect at the lock arm rear of protective bulkhead 37 It is provided with a pair detection part protective bulkhead 38.Connected by two detection parts protective bulkhead 38 and the moon The space of the upper surface division connecing device housing 27 constitutes the receiving space of detection part 39.Such as figure Shown in 12, detection part protective bulkhead 38 is positioned at outside the width of lock arm protective bulkhead 37 Side, as shown in figure 14, the rear end face of lock arm protective bulkhead 37 and detection part protective bulkhead Inside the width of 38 relatively.

As shown in figure 12, two detection parts with the upper end of protective bulkhead 38 all towards inner side and Bend in approximate right angle.And, two detection part upper ends of the front end of protective bulkhead 38 Highlight upward, and then curve inwardly together and become a pair reversion width is relative and prevent Stop 40.On the other hand, the width both sides releasing operating portion 36 of lock arm 33 Stretch out outside width and form flange part 41 respectively.Thus, at lock arm 33 to lifting Direction distortion time, two flange parts 41 abut with the inner side of reversion preventing portion 40, it is thus possible to Enough prevent lock arm 33 from exceeding elastic limit and tilting deformation.

Further, detection part by the rear end lower of protective bulkhead 38 with outside width and rear The mode stretched out is formed and becomes and bloat frame portion 42.As shown in figure 12, two bloat frame portion 42 Be formed as C font the most unlimited in the backsight visual angle of female connector housing 27 or anti-C word Type.

As shown in Figure 13 etc., at two detection parts with the inner surface of protective bulkhead 38 respectively at width Degree direction has been arranged in pairs after carrying out detection part 39 at initial position and detection position Move back first, second locking supporting part 43,44 of restriction.As shown in figure 12, two locking supporting part 43,44 in the way of will not blocking the most each other in backsight visual angle in short transverse Offset and configure.Thereby, it is possible to by de-by front-rear direction of two locking supporting parts 43,44 Mould and shape.

And, as shown in figure 14, two locking supporting parts 43,44 are positioned at lock arm protective bulkhead 37 towards rear extend time extended line width outside.As shown in figure 13, two locking The the first locking supporting part 43 being positioned at rear side in support part 43,44 is positioned at low level side, with the moon even The upper wall connecing device housing 27 is continuous.First locking supporting part 43 be used for avoiding detection part 39 from Initial position is rearward deviate from, and as shown in figure 14, the rear surface of the first locking supporting part 43 becomes For conical surface 43A, and its front surface becomes the locking supporting surface 43B of setting.

On the other hand, it is positioned at than the first locking supporting part 43, the second locking supporting part near front side 44 are positioned at high-order side, are used for making female connector housing 27 be difficult to from detection position and rearward move. As shown in figure 14, the second locking supporting part 44 is each formed with the conical surface 44A, 44B in front and rear surfaces. But, at the conical surface 44A, 44B front and back, incline direction is opposite each other, and the conical surface 44B of front side Angle is slightly steep, is formed as the state close to setting.

(detection part 39)

Figure 15 to Figure 17 illustrates detection part 39.Detection part 39 is with can be at Figure 11 and Tu Initial position shown in 18 and the mode group of movement between the detection position shown in Figure 19, Figure 20 It is loaded on female connector housing 27.Detection part 39 can be by whether can be pressed into from initial position Detect male and female connectors F to detection position, whether M becomes correct chimerism.

Detection part 39 is also synthetic resin system, it possess matrix part 45 and with matrix part 45 The elastic arm 46 that front surface is integrally connected.Elastic arm 46 be forwards in single armed beam-like ground The form extended.Elastic arm 46 constitutes substantially square rod shape, and it can be with root portion as fulcrum In short transverse flexural deformation.In its natural state, the gradient inclination with forward upward is become Form.

The upper front end prominent teat being formed with substantially square block upward elastic arm 46 47.At the upper surface of teat 47, it is protruding that the central part of width is ribbed ground, forms auxiliary Teat 48.Forwards highlight in the bottom of the front end face of elastic arm 46 and be formed with abutting part 49. As shown in figure 11, when detection part 39 is positioned at initial position, abutting part 49 enters into setting In the receiving space S of the lower section of the locking projection 34 in lock arm 33.Therefore, in negative and positive When adapter F, M are fitted together to, when lock arm 33 flexural deformation downwards, pass through locking projection Abutting part 49 is depressed by the lower surface of 34, therefore elastic arm 46 and lock arm 33 interlock and to Lower section flexural deformation.

As shown in figure 11, the upper surface at teat 47 is formed becomes upward towards rear The guide surface 50 of the taper of degree.And then, the front surface at teat 47 is substantially erected to be formed with shifting Dynamic restriction face 51.Mobile restriction face 51 is in can when detection part 39 is positioned at initial position State that is relative with the front end face of locking projection 34 and that abut, thereby, it is possible to limit detection part 39 move to detection position from initial position accidentally.

In the midway that male and female connectors F, M are correctly fitted together to, locking projection 34 and the lock in cover portion 3 Determine teat 7 sliding contact and lock arm 33 is depressed.With this concomitantly, elastic arm 46 is also It is depressed.When male and female connectors F, M are correctly fitted together to, lock arm 33 restores, and by Locking teat 7 in auxiliary teat 48 quilt cover portion 3 presses, and therefore elastic arm 46 keeps quilt The state of pressure, as a result of which it is, move supporting of the restriction face 51 terminal surface with locking projection 34 The state of connecing is released from, and detection part 39 becomes the situation can advanced towards detection position.

On the other hand, the rear surface of matrix part 45 becomes push operation wall 52.As Figure 15,16 Shown in, the width both sides of push operation wall 52 are formed as step-like in the height direction, Its bottom becomes stretches out most first step portion 52A laterally.At detection part 39 just The period of movement between beginning position and detection position, this first step portion 52A can bloat frame Move in portion 42.Upper surface at two first step portion 52A is prominent respectively, and to be formed with end sharp-pointed Slide protrusion 53, and the top wall surface bloated in frame portion 42 substantially point cantact, thus play reduction Effect to resistance to sliding during detection part 39 push operation.And, push operation wall 52 The second end 52B formed higher than the upper surface of matrix part 45, forwards prolong from its front surface Stretch out a pair side walls 54.Two side walls 54 are formed as being embedded into female connector housing The detection part of the 27 sides inner side of protective bulkhead 38.

As shown in figure 17, from front end between the leading section of two side walls 54 and matrix part 45 A pair slit 55 of incision is played in side, face, is being formed than the slit 55 position outside width The locking arm 56 that a pair can bend.

Two locking arm 56 be formed as can in width lateral bend.And, such as Figure 16 Shown in, the terminal part two locking arm 56 outwards and is the most side by side provided with the first claw 57 With the second claw 58.The first claw 57 being wherein positioned at low level side can be with female connector housing First locking supporting part 43 of 27 sides is locking.As shown in figure 15, the rear surface of the first claw 57 Be formed as the locking face 59 erect, when detection part 39 is positioned at initial position, itself and the first card The locking supporting surface 43B determining supporting part 43 is locking.Now, locking face 59 and locking supporting surface 43B is the face of setting and the most locking, limits at the beginning of detection part 39 is in the most strongly Rearward abjection during beginning position.

On the contrary, side is the conical surface before and after the second claw 58, front end face 58A is along width The face in degree direction, i.e. along the face in the direction orthogonal with the pressing direction of detection part 39.Therefore, As shown in figure 18, when detection part 39 is positioned at initial position, the second claw 58 and the second card The rear surface determining supporting part 44 abuts, thus the advance that auxiliary carries out detection part 39 limits. And, as shown in figure 19, when detection part 39 is positioned at detection position, the second claw 58 with Second locking supporting part 44 is locking and the rear end of its front end face 58A and lock arm protective bulkhead 37 Face is relative in the way of can abutting, so that detection part 39 will not be entered one from detection position Step is forwards pressed into.

It addition, as shown in Figure 18, Figure 19, be positioned at initial position and detection at detection part 39 During position, two locking arm 56 be located substantially at lock arm protective bulkhead 37 towards rearward prolongation On line, when two locking arm 56 inside lateral bend deformation, through this prolongation inside width Line.Thereby, it is possible to using locking as two for the Dead space at the rear of lock arm protective bulkhead 37 The curved space of arm 56 utilizes.

Then, the action effect of the embodiment constituted in the above described manner is illustrated.Such as Fig. 9 Shown in, in the case of male accessory 5 is assembled in male connector housing 1, keeper 10 It is maintained at interim locking state.Now, the locking projection 22 of foot section 20 all keeps out of the way chamber The outside of body 4, therefore, it is possible to be inserted into cavity 4 by male accessory 5.It is inserted into tram Till male accessory 5 locking by convex shaped part 6 first stage.

It follows that when the press-in face 19 of keeper 10 is carried out push operation, foot section 20 Inwardly lateral bend deformation, thus locking pawl 21 disengages the locking shape with interim locking supporting part 16 State, keeper 10 entirety is inserted hole 8 to keeper and is inserted into.Then, arrive when keeper 10 When reaching formal catch positions, locking pawl 21 is locking and locking with formal locking supporting part 17 Teat 22 is locking with male accessory 5 in entering cavity 4, therefore male accessory 5 and convex Portion 6 becomes the state of dual anticreep together.

It addition, the operation that female end subassembly 29 is assembled into female connector housing 27 can also be used Main points same as described above are carried out.

It follows that the operation to making male and female connectors F, M chimeric illustrates.With sun even Connecing in the female connector F before device M is fitted together to, detection part 39 is maintained at detection position.At this Under state, make male and female connectors F, M chimeric, during this is chimeric, female connector housing The end side of 27 is fitted in cover portion 3, the locking projection 34 of lock arm 33 and the lock in cover portion 3 The front end determining projection 7 abuts.When so carrying out chimeric, lock arm 33 is by locking projection 7 Depressing force and flexural deformation downwards.When lock arm 33 is depressed, detection part 39 The also flexural deformation downwards by depressing force of the abutting part 49 of elastic arm 46.

Then, when male and female connectors F, M are fitted together to correct depth, negative and positive terminal is joined Part 1,27 the most also becomes correct connection status, and lock arm 33 restores, locking projection 34 is locking with the inner surface side of the locking teat 7 in cover portion 3.Now, due to the locking in cover portion 3 Teat 7 abuts with the auxiliary teat 48 of elastic arm 46, and therefore elastic arm 46 becomes continuation The most diastrophic state.Now, become the mobile restriction face 51 of elastic arm 46 with The state that the front end face of the locking projection 34 of lock arm 33 abuts, becomes detection part 39 The state that mobile restriction state is released from.Therefore, when push operation wall 52 is pressed, Before the guide surface 50 of the teat 47 in elastic arm 46 and the locking projection 34 of lock arm 33 End lower edge sliding contact, thus elastic arm 46 presses under side further downward, and test section Part 39 reaches to detect position.In this position, the teat 47 of elastic arm 46 enters into lock arm Become relative to both sides between locking projection 34 and the upper surface of female connector housing 27 of 33 Substantially abut state.Accordingly, because achieve the lock arm 33 bending limit to locking releasing direction System, therefore, it is possible to lock the chimerism of male and female connectors F, M effectively.

And, if arriving detecting position at detection part 39 to be set to period enforcement only to test section The press-in of part 39, first departs from the first claw 57 and the first locking supporting part of locking arm 56 The hold mode of 43 locking initial positions.Then, locking arm 56 inside lateral bend each other, the Two claws 58 cross the second locking supporting part 44.When detection part 39 reaches to detect position, Second claw 58 is locking with the second locking supporting part 44, and the front end face 58A of the second claw 58 Abut with the rear end face of lock arm protective bulkhead 37, thus realize stopping before detection part 39 Dynamic.

The effect of the present embodiment is as described below.

(1) in keeper 10, enlarged portion 11 is set from main part 18, except main part Side pressure is also formed with enlarged portion side pressure and enters face 19B outside entering face 19A.Thus, even small-sized Keeper 10, it is also possible to easily carry out the push operation of keeper 10 entirety.And, by Expansion in press-in face 19 is carried out at unilateral (rear side) only with respect to main part 18, therefore to Keeper inserts the insertion posture in hole 8 and easily becomes inclination attitude.But, in the present embodiment, It is provided with correcting posture portion 23, by its leading section being embedded the notch recesses 15 of partition wall 14 (with reference to Fig. 8), it is possible to keeper 10 is corrected into and is properly inserted posture and inclines without becoming Tiltedly posture.

(2) and, in keeper 10, correcting posture portion 23 is arranged at two foot section Between 20, therefore correcting posture portion 23 can also play the overbending limiting two foot section 20 Function.

(3) and then, in two enlarged portion 11 of keeper 10, outside width two Side is prominent forms anti-loosening projection 25, when keeper 10 is positioned at formal catch positions, two Anti-loosening projection 25 is extruded by the inner surface of two sidewalls, and therefore two enlarged portion 11 are in central authorities Between wall and two side held with state very close to each other such that it is able to by overall for keeper 10 Remain in the direction of the width and do not loosen.Further, protruding outside to width at keeper 10 It is formed a pair and loosens limiting unit 26, when keeper 10 is positioned at formal catch positions, two pines Dynamic limiting unit 26 is recessed substantially without the location of the correspondence being embedded into male connector housing 1 side with gap Between portion 13, therefore, it is possible to keeper 10 is protected with the state the most not loosened Hold.

(4) in the female connector F of the present embodiment, when detection part 39 is positioned at initial position With detection position time, when two locking arm 56 be located substantially at lock arm protective bulkhead 37 towards On the extended line at rear, when the inside lateral bend of two locking arm 56 deforms, in width Side passes this extended line.That is, configuration Dead space at the rear of lock arm protective bulkhead 37 is utilized Locking arm 56, and make they inside lateral bend deformation.Thus, bend laterally with locking arm 56 The mode of deformation is compared, it is possible to make adapter miniaturization in the direction of the width.

(5) in female connector housing 27 so that for detection part 39 is maintained at initially First, second locking supporting part 43,44 of position and detection position is the most overlapping And offset configuration, therefore, it is possible to make described first, second locking supporting part 43,44 by along front Rear shapes to the shaping dies of opening and closing.Therefore, it is possible to make the mould for female connector housing 27 Lamps structure simplifies.

(6) when detection part 39 is in initial position, except the elastic arm of detection part 39 Outside the front end in portion 46 abuts with lock arm 33, the second claw 58 of two locking arm 56 with The rear surface of the second locking supporting part 44 abuts, and realizes the advance of initial position the most effectively Limit.And, at initial position, the first claw 57 is locking with the first locking supporting part 43, And their locking and locking supporting surface are the face of setting, each other therefore, it is possible to prevent effectively The situation that only detection part 39 comes off laterally at initial position.

(7) when detection part 39 is positioned at detection position, the second claw of detection part 39 The front end face 58A of 58 abuts with the rear end face of lock arm protective bulkhead 37, thus detects The advance of parts 39 limits.Meanwhile, the second claw 58 and front table of the second locking supporting part 44 Face is locking, it is achieved that to the non-return of initial position.
