As shown in Figure 1, connector 1 comprises: cloudy terminal shell 5, in this cloudy terminal shell 5, form multiple terminal accommodating chamber 4, and female end 3 with contact site (not shown) inserts individually and is received in the plurality of terminal accommodating chamber 4; And cloudy terminal shell 8, this cloudy terminal shell 8 keeps multiple male 7, the plurality of male 7 produces sliding contact to be connected to female end 3 with this contact site, and the busbar 6 male 7 being connected to external conductor (as an example, earthing conductor) is insert molded in this cloudy terminal shell 8.Then, in connector 1, together with cloudy terminal shell 5 is fitted to male housing 8, thus make together with female end 3 is electrically connected to male 7.

Female end 3 is all formed as comprising: contact terminal portion 3b, and comprising in this contact terminal portion 3b can the contact site of strain, and this contact terminal portion 3b is formed as tubular; Crimp type terminal portion 3c, electric wire 2 is fastened in this crimp type terminal portion 3c; And endless member (as an example, annular seal ring) 2a, this endless member 2a is arranged on the peripheral of the end of electric wire 2.The terminal accommodating chamber 4 of cloudy terminal shell 5 is all formed as comprising: rectangular drum like accommodating chamber (hereinafter, referred to rectangular drum like portion), and the contact terminal portion 3b of female end 3 is contained in this accommodating chamber; And tubular accommodating chamber (hereinafter, referred to cylindrical portion) 4b, the crimp type terminal portion 3c of female end 3 and the annular seal ring 2a of electric wire 2 are contained in this tubular accommodating chamber.Rectangular tubular portion is positioned to than cylindrical portion 4b closer to cloudy terminal shell 8.Although suppose that material has elasticity, is not particularly limited the material of cloudy terminal shell 5, in this embodiment, cloudy for description terminal shell 5 is formed from a resin as an example.

In this case, be formed in can strain contact terminal portion 3b a side in lock hole (not shown) produce with the shaft (not shown) be formed in by elastomeric element on the inwall of terminal accommodating chamber 4 and engage, thus can prevent female end 3 from misplacing from terminal accommodating chamber 4 (directly describing, cloudy terminal shell 5).Such as, shaft is formed on the inwall of predetermined side (as an example, downside) in the Y direction in the rectangular tubular portion of terminal accommodating chamber 4.In this case, shaft can be made up of the material identical with the material of cloudy terminal shell 5, and can extend to the rectangular drum like portion of the contact terminal portion 3b holding female end 3 by the cylindrical portion 4b of the terminal accommodating chamber 4 shaft being formed as the annular seal ring 2a from the crimp type terminal portion 3c and electric wire 2 holding female end 3 and make shaft be formed integrally as cantilevered construction.A shaft is arranged to each terminal accommodating chamber 4, and therefore, for cloudy terminal shell 5, the shaft with the number of female end 3 should be formed.

The shaft formed in the above described manner is by female end 3 pressing, thus shaft and the lock hole in female end 3 be inserted in terminal accommodating chamber 4 produce engage before (hereinafter, this state is called half insert state) flexibly deflect to be out of shape, and shaft and the lock hole in female end 3 be inserted in terminal accommodating chamber 4 produce engage after (hereinafter, this state is called suitable insert state), this shaft flexibly deflects to be deformed into its initial position.Particularly, under half insert state, shaft elastic deflection is to be out of shape thus to exit (as an example, in the Y direction downwards) from the rectangular drum like portion of terminal accommodating chamber 4.Then, under suitable insert state, the position in female end 3 is formed at lock hole, shaft elastic deflection is to be deformed to its initial position, thus the rectangular drum like portion entering terminal accommodating chamber 4 (as an example, in the Y direction upwards), thus shaft is produced with the lock hole in female end 3 engage.Under suitable insert state, female end 3 locks together with shaft, thus prevents female end 3 from misplacing from terminal accommodating chamber 4.

Busbar 6 is insert molded in male housing 8.In this embodiment, male 7 is arranged on to give prominence to from busbar 6 on busbar 6, thus is inserted in female end 3 to be attached thereto.Fig. 2 is the perspective view of the structure that busbar 6 is shown.As shown in Figure 2, male 7 and busbar 6 form.In this case, male 7 is made up of the electric conducting material identical with the material of busbar 6.The end of male 7 is formed as the rectangular drum like portion of the terminal accommodating chamber 4 entering cloudy terminal shell 5, to be slidably connected with the contact site of female end 3.Such as, busbar 6 can be made by punching press or bending metals conducting plate.When processing metallic conduction flat board to manufacture busbar 6 as mentioned above, male 7 can be formed together with busbar main part 6a.Then, the resin arm 80 that will be described later, resin connecting portion 83 and resin cover 84 (with reference to figure 1) and busbar 6 are insert molded integratedly, thus make male housing 8, busbar 6, arm 80, connecting portion 83 are integrated into this male housing 8 with covering part 84.

In the structure shown in Fig. 2, male 7 is given prominence to from the both ends the Y-direction of plate-shaped bus bars main part 6a, and this busbar main part 6a extends along the X direction and then extends into plate-like shape towards the closure (direction shown in the arrow A 11 in Fig. 1) with female end 3.In addition, connecting portion 6b, 6c and the cradle portion 81 that will be described later are arranged on busbar main part 6a continuously, and male 7 is connected to external conductor (as an example, earthing conductor) via this connecting portion 6b, 6c.In this case, busbar main part 6a is covered by covering part 84, and integrated with arm 80 and connecting portion 83.Male 7, connecting portion 6b, 6c and cradle portion 81 are given prominence to from the covering part 84 constructed as mentioned above, thus are exposed to the outside (with reference to figure 1) of male housing.Fig. 2 illustrates that eight male 7 are altogether arranged with roughly equal interval and four male 7 are arranged to the structure that extends from each end the Y-direction of busbar main part 6a as an example.Certainly, male 7 should be formed accordingly with the quantity of female end 3 be inserted in terminal accommodating chamber 4, and at random can set the quantity of male 7.In addition, annular seal member (such as, waterproof grommet etc.) is arranged between cloudy terminal shell 5 and male housing 8, thus anti-sealing enters the connecting portion between female end 3 and male 7, this gives connector 1 with water proof structure.

As described above, connector 1 is configured so that: when being entrenched togather with male housing 8 by cloudy terminal shell 5, and female end 7 produces sliding contact to be connected with the contact site of female end 3.When it happens, cloudy terminal shell 5 and male housing 8 are formed at the first nested position and the second nested position place (that is, with two stages) is fitted to together.First nested position be female end 3 to be inserted in terminal accommodating chamber 4 and contact site in the face of the position of male 7, and the first nested position is set in before male 7 produces the position of sliding contact with the contact site of female end 3.The contact site second nested position being set to female end 7 and female end 3 produces the position of sliding contact.In the following description, the state that cloudy terminal shell 5 and male housing 8 are parked in the first nested position is called the first chimerism, and the state cloudy terminal shell 5 and male housing 8 being parked in the second nested position is called the second chimerism.Under the first chimerism and the second chimerism, the lock hole in female end 3 engages with shaft, and any one chimerism in two kinds of chimerisms corresponds to suitable chimerism.By this way, connector 1 is constructed such that: when cloudy terminal shell 5 transfers the second chimerism (moving to the second nested position from the first nested position) with male housing 8 to from the first chimerism, male 7 produces sliding contact with the contact site of female end 3.This is divided into the load realizing the first chimerism and the load realizing the second chimerism by applying with the load making female end 3 connect together with male 7, thus reduces for the maximum load in the above described manner needed for splicing ear.

In this embodiment, arm 80 and cradle portion 81 are arranged on male housing 8.Arm 80 is formed from a resin, and in the upper extension in the chimeric direction (direction by shown in the arrow A 11 in Fig. 1) being fitted to cloudy terminal shell 5, and cradle portion 81 is made of metal, and arrange continuously with busbar 6, chimeric direction extends.

Arm 80 extends into plate-like shape from the both sides the X-direction of male housing 8 towards the outer peripheral face of cloudy terminal shell 5 (especially, the lateral surface 4d relevant with X-direction of the housing department 4c in rectangular drum like portion).Arm 80 has groove portion (hereinafter, referred to lock slots) 82, and this groove portion 82 is formed as extending along the chimeric direction (Z-direction) of male housing 8 and cloudy terminal shell 5.In this embodiment, two arms 80 are arranged to extend from each sidepiece the X-direction of male housing 8, and thus, four arms 80 are arranged to extend towards the lateral surface 4d of housing department 4c altogether.That is, one group of two arm 80 (80a, 80b and 80c in Fig. 1,80d) is arranged on each sidepiece in the X-direction of male housing 8, is formed a pair such group with the both ends place in the X-direction of male housing 8.According to this structure, arm 80 is being fitted to from the both sides extension the X-direction of male housing 8 on the chimeric direction of cloudy terminal shell 5 (direction by shown in the arrow A 11 in Fig. 1), thus is remained between arm 80 by the housing department 4c of cloudy terminal shell 5.In addition, on each sidepiece in the X-direction of male housing 8, these group of two arm is arranged to all place an arm to the often end in the Y-direction of male housing 8.Then, these arms 80 connect together via two connecting portions 83 at the both sides place at male housing 8.That is, on the both sides of male housing 8, two arms 80 (such as, 80a, 80c) arranging one end place in the Y direction connect together via a connecting portion 83.Similarly, two arms 80 (such as, 80b, 80d) at the other end place arranged in the Y direction connect together via another connecting portion 83.Two connecting portions 83 extend all along the X direction, thus (between 80a and 80c and between 80b and 80d) stretches between two arms 80.Two connecting portions 83 are all integrated with the arm 80 (80a and 80c and 80b and 80d) at its two ends place.

The outer peripheral face of cradle portion 81 from the sidepiece the X-direction of busbar 6 towards cloudy terminal shell 5 (particularly, from busbar main part 6a towards the lateral surface 4d the X-direction of housing department 4c) extends into plate-like shape.That is, cradle portion 81 and busbar 6 are arranged continuously, thus integrated with it.According to this structure, when cradle portion 81 is locked by the mosaic process 52 on the cloudy terminal shell 5 that will be described later, busbar 6 is located relative to cloudy terminal shell 5 simultaneously and is fixed.As a result, such as, when the male be arranged on busbar 67 is inserted in female end 3, can limits between terminal and produce small slip, thus make it possible to limit the wearing and tearing that male 7 and female end 3 stand small slip.

In this embodiment, single cradle portion 81 extends from the sidepiece the X-direction of busbar 6 towards the lateral surface 4d of housing department 4c.When it happens, cradle portion 81 is arranged on the sidepiece in the X-direction of busbar 6, and the sidepiece place that cradle portion 81 is positioned in the X-direction of male housing 8 is arranged between one group of two arm 80 (80a, 80b shown in Fig. 1) at two ends place in the Y direction.The docking section (the extending end 81b shown in Fig. 3 (c) He 4 (c)) of cradle portion 81 is formed as outward-dipping, thus taper is become on chimeric direction (direction by shown in the arrow A 11 in Fig. 1), when to make together with cloudy terminal shell 5 and male housing 8 start to be fitted to and then to transfer the second chimerism (from the first nested position to the second nested position) to from the first chimerism, when this docking section is docked with mosaic process 52, this docking section can easily ride in the mosaic process 52 on cloudy terminal shell 5.In this case, the extending end 81b of cradle portion 81 tilts, thus along the gradient of mosaic process 52.The extension size of cradle portion 81 is set to that extending end 81b is positioned on chimeric direction (direction by shown in the arrow A 11 in Fig. 1) is more outstanding than arm 80.Hole portion 81a is formed in cradle portion 81 near extending end 81b, thus runs through cradle portion 81 in the X direction.Fig. 2 show hole portion 81a be circular structure as an example.Hole portion 81a is such hole: when cloudy terminal shell 5 and male housing 8 are in the second nested position, the mosaic process 52 of the cloudy terminal shell 5 that will be described later is entrenched in this hole, and can set the structure (size and dimension) of this hole portion 81a according to the structure of mosaic process 52.

In contrast, produce with the lock slots 82 be formed in arm 80 at the first nested position place engage the first copulational protuberance 50, to produce the second copulational protuberance 51 engaged with the lock slots 82 in arm 80 at the second copulational protuberance 51 place, the guide portion 53 being embedded in the mosaic process 52 in the hole portion 81a that is formed in cradle portion 81 in the second joint place and cradle portion 81 being directed to mosaic process 52 is arranged on cloudy terminal shell 5.

First copulational protuberance 50 is arranged to give prominence to from the lateral surface 4d of housing department 4c in the mode that the lock slots 82 to arm 80 is mutually corresponding.In this embodiment, two the first copulational protuberances are arranged on each lateral surface 4d in the X-direction of housing department 4c, thus give prominence to from this lateral surface 4d, and therefore, four the first copulational protuberances 50 are arranged to become roughly rectangular shape from lateral surface 4d is outstanding altogether.That is, one group two the first copulational protuberances 50 (as an example, 50a, the 50b shown in Fig. 1) are arranged on each sidepiece in the X-direction of cloudy terminal shell 5, each sidepiece in the X-direction of cloudy terminal shell 5 to be formed a pair such group.In addition, on each sidepiece in the X-direction of cloudy terminal shell 5, these one group two first copulational protuberances 50 are arranged to all place first copulational protuberance to the often end in the Y-direction of housing department 4c.In the first copulational protuberance 50, docking section is formed obliquely towards lateral surface 4d, thus taper is become on chimeric direction (direction by shown in the arrow A 12 in Fig. 1), when making together with cloudy terminal shell 5 and male housing 8 start to be fitted to, when arm 80 docks with docking section, docking section makes arm 80 easily to ride on docking section.

Second copulational protuberance 51 is arranged to give prominence to from the lateral surface 4d of housing department 4c in the mode that the lock slots 82 to arm 80 is mutually corresponding.In this embodiment, two the second copulational protuberances are arranged on each lateral surface 4d in the X-direction of housing department 4c, thus give prominence to from this lateral surface 4d, and therefore, four the second copulational protuberances 51 are arranged on housing department 4c altogether, thus give prominence to as roughly rectangular shape from housing department 4c.That is, one group two the second copulational protuberances 51 (as an example, 51a, the 51b shown in Fig. 1) are arranged on each sidepiece in the X-direction of cloudy terminal shell 5, are formed a pair such group with two sidepiece places in the X-direction of cloudy terminal shell 5.In addition, on each sidepiece in the X-direction of cloudy terminal shell 5, these one group two second copulational protuberances 51 are arranged to all place second copulational protuberance for the often end in the Y-direction of housing department 4c.In the second copulational protuberance 51, docking section is formed obliquely towards lateral surface 4d, thus taper is become on chimeric direction (direction by shown in the arrow A 12 in Fig. 1), when to make together with cloudy terminal shell 5 and male housing 8 start to be fitted to and then to transfer the second chimerism (moving to the second nested position from the first nested position) to from the first chimerism, when arm 80 abuts with docking section, docking section makes arm 80 easily to ride on docking section.

First copulational protuberance 50 and the second copulational protuberance 51 have roughly the same size and dimension, and the X-direction about lateral surface 4d being both positioned at lateral surface 4d is on the side of male housing 8.Particularly, first junction surface 50 is positioned to be arranged in relative on the nearside (corresponding with the first nested position) on the chimeric direction being fitted to male housing 8 (direction by shown in the arrow A 12 of Fig. 1), and the second copulational protuberance 51 is positioned to be positioned on the distally (corresponding with the second nested position) relative to identical chimeric direction.That is, it is corresponding that the space between the first junction surface 50 so arranged and the second junction surface 51 and cloudy terminal shell 5 and male housing 8 move to from the first nested position the distance that the second fitting portion crosses.In other words, when cloudy terminal shell 5 and male housing 8 move to the second nested position from the first nested position, first copulational protuberance 50 and the second copulational protuberance 51 should be arranged on the two ends place in the Y-direction of housing department 4c respectively, and are limited to therebetween along the Z-direction of lateral surface 4d in corresponding space mutually with the relative movement distance in chimeric direction (Z-direction).

Mosaic process 52 is arranged to give prominence to from the lateral surface 4d of housing department 4c, thus corresponding with the hole portion 81a in cradle portion 81.In this embodiment, mosaic process 52 is made to protrude projected curved surface (as an example, outstanding sphere) from a lateral surface 4d the X-direction of housing department 4c.When it happens, mosaic process 52 arranges on a lateral surface 4d in the X direction, thus the roughly pars intermedia place be positioned between one group of first copulational protuberance 50 (50a, 50b shown in Fig. 1) and between one group of second copulational protuberance 51 (51a, 51b shown in Fig. 1), this two groups of copulational protuberances side in the X-direction of housing department 4c is arranged two ends place in the Y direction, and be arranged on contrary end, the end that arranges about X-direction with the first copulational protuberance 50 and the second copulational protuberance 51.In addition, mosaic process 52 is arranged on a lateral surface 4d in the X direction, thus is positioned at the roughly pars intermedia in Y-direction and this both direction of Z-direction about rib 53a, the 53b of the guide portion 53 on the side in the X-direction being arranged on housing department 4c that will be described later.

Mosaic process 52 is entrenched in the projection in the hole portion 81a in support 81, and therefore, should set the structure (size, shape etc.) of this mosaic process according to the structure of hole portion 81a.As an example, in this embodiment, by on cloudy terminal shell 5 (particularly, on lateral surface 4d) the diameter of circular cross-section of mosaic process 52 be set to the opening diameter being substantially equal to hole portion 81a, make mosaic process 52 can protrude projected curved surface (as an example, outstanding sphere) from the lateral surface 4d of cloudy terminal shell 5.When cloudy terminal shell 5 and male housing 8 move to the second fitting portion from the first fitting portion, this state making mosaic process 52 can closely be attached to the edge of opening of hole portion 81a with mosaic process 52 is entrenched in hole portion 81a.Then, after mosaic process 52 is entrenched in hole portion 81a by this way, can limit between cloudy terminal shell 5 and male housing 8 any loosen, that is, the resistance to vibration of connector 1 can be improved, thus make it possible to keep chimerism.That is, mosaic process 52 and hole portion 81a can give connector 1 with slide lock (by locking) structure.Cradle portion 81 is made of metal, and rigidity is high compared with situation about being therefore formed from a resin with it, thus make it possible to improve upper about all directions (such as, Y-direction and Z-direction) on side 4d except for the outer outside the vertical direction about lateral surface 4d (X-direction) on loosening restriction (raising resistance to vibration) effect.

Guide portion 53 comprises a pair hook rib 53a, 53b, this a pair hook rib is arranged to extend abreast along cloudy terminal shell 5 with the chimeric direction (Z-direction) of male housing 8, and guides this cradle portion 81 while remaining between rib 53a, 53b by cradle portion 81.In other words, guide portion 53 is by hook rib 53a, 53b and be limited to space between rib 53a, 53b (hereinafter, be called guiding groove) 53c composition, on the lateral surface 4d of housing department 4c, this hook rib 53a, 53b are positioned to and face one another with being limited with predetermined space betwixt.In this embodiment, rib 53a, 53b is arranged on the lateral surface 4d (that is, being provided with the lateral surface 4d of mosaic process 52) in the X-direction of housing department 4c.When it happens, rib 53a, 53b separated from each other separate the distance of the width in the Y-direction being substantially equal to support 81 while give prominence to from a lateral surface 4d, and bending about on the rightabout of Y-direction thereafter, thus the distance between rib 53a, 53b is narrowed.Rib 53a, 53b are projected into the height of the thickness being in the X direction substantially equal to support 81 from lateral surface 4d.This structure can limit and make support 81 can be contained in space between rib 53a, 53b, and the space so limited forms guiding groove 53c.

That is, cradle portion 81 moves along rib 53a, 53b, thus after cradle portion 81 enters guiding groove 53c, cradle portion 81 is directed to the mosaic process 52 of cloudy terminal shell 5.When it happens, because cradle portion 81 guided by guide portion 53 while being maintained between rib 53a, 53b, so when cloudy terminal shell 5 and male housing 8 move to the second nested position from the first nested position, limit these housings 5,8 in the Y direction loosen.In addition, rib 53a, 53b should should be set to such size about Z-direction (the chimeric direction of cloudy terminal shell 5 and male housing 8): make under the first chimerism, the part be arranged near extending end 81b of cradle portion 81 can be contained in guiding groove 53c, and under the second chimerism, be arranged in the comprising of cradle portion 81 and can be contained in guiding groove 53c near the only about half of of extending end 81b.

Herein, by be described through cloudy terminal shell 5 is fitted to male housing 8 together with and the example of the process that they are fitted together.The assembling of terminal shell is performed: namely with two stages, male housing 8 is entrenched on cloudy terminal shell 5 to realize the first chimerism, to make female end 3 be inserted in corresponding terminal accommodating chamber 4 to realize the stage of suitable insert state (that is, female end 3 can be connected to the state of male 7); And make male 7 and the contact site of female end 3 produce sliding contact, with realize male 7 to be electrically connected to female end 3 together with another stage of the second chimerism.Fig. 3 (a) to (c) illustrates that cloudy terminal shell 5 and male housing 8 are positioned at the state of the first nested position (the first chimerism).Fig. 3 (a) is perspective view, and Fig. 3 (b) is end view, and Fig. 3 (c) be along by shown in the arrow A 3 in Fig. 3 (b) line intercept and from by shown in arrow A 3 direction watch horizontal sectional view.In addition, Fig. 4 (a) to (c) illustrates that cloudy terminal shell 5 and male housing 8 are positioned at the state (the second chimerism) of the second nested position.Fig. 4 (a) is perspective view, and Fig. 4 (b) is end view, and Fig. 4 (c) be along by shown in the arrow A 4 in Fig. 4 (b) line intercept and from by shown in arrow A 4 direction watch horizontal sectional view.Note, in Fig. 3 (a), 3 (c) and 4 (a), (c), eliminate female end 3 and female end 3 is not shown.

Realizing in the first chimerism, cloudy terminal shell 5 is relative to each other located with male housing 8, makes the first copulational protuberance 50 at a right angle with arm 80.Then, the extending end of arm 80 produces with the first copulational protuberance 50 and abuts.When applying predetermined thrust (acting on by the power on the direction shown in the arrow A 11 in Fig. 1) in this condition, arm 80 elastic deflection is with distortion, thus laterally expand outwardly about X-direction against the thrust applied, and finally ride on the first copulational protuberance 50.Then, when arm 80 rides on the first copulational protuberance 50 completely, arm 80 elastic deflection with to internal strain, thus returns to its initial position from lateral magnification situation.As a result, the lock slots 82 that the first copulational protuberance 50 enters in arm 80 engages to produce with lock slots 82, thus arm 80 is locked in appropriate location.In other words, cloudy terminal shell 5 is positioned at the first nested position with male housing 8.Then, female end 3 is inserted in corresponding terminal accommodating chamber 4, and the conjugate foramen in female end 3 is locked by shaft, thus prevents female end 3 from misplacing from terminal accommodating chamber 4.This makes cloudy terminal shell 5 and male housing 6 enter the first chimerism (state shown in Fig. 3 (a) to (c)).When realizing the first chimerism by this way, in order to remove cloudy terminal shell 5 and the Qian He of male housing 8, make arm 80 bending thus the locking of contact lock slots 82 and the first copulational protuberance 50.Thus, only need the contact force making arm 80 bending.

When maintain at the extending end of arm 80 abut with the first copulational protuberance 50 applied thrust time, cradle portion 81 enters guiding groove 53c while directed along rib 53a, 53b of guide portion 53.Then, when the first copulational protuberance 50 locks arm 80 and cloudy terminal shell 5 and male housing 8 are positioned at the first nested position, cradle portion 81 be arranged near its extending end 81b be partially received in guiding groove 53c.That is, at the first nested position, cradle portion 81 is in the state (state shown in Fig. 3 (c)) that extending end 81b contacts with the mosaic process 52 of cloudy terminal shell 5.

When cloudy terminal shell 5 transfers the second chimerism with male housing 8 to from above-mentioned first chimerism, thrust is applied to and is on the male housing 8 of the first chimerism, and the extending end of arm 80 produces with the second copulational protuberance 51 and abuts.When in this condition further applied thrust time, arm 80 elastic deflection with distortion, thus laterally expands outwardly about X-direction against thrust, and then arm 80 rides on the second copulational protuberance 51.Then, when arm 80 rides on the second copulational protuberance 51 completely, arm 80 elastic deflection with to internal strain, thus returns to its initial position from lateral magnification situation.As a result, the lock slots 82 that the second copulational protuberance 51 enters in arm 80 engages to produce with lock slots 82, thus arm 80 is locked in appropriate location.That is, cloudy terminal shell 5 is positioned in the second nested position with male housing 8.This makes cloudy terminal shell 5 enter the second chimerism (state shown in Fig. 4 (a) to (c)) with male housing 8.Under above-mentioned second chimerism, the first copulational protuberance 50 also keeps engaging with the lock slots 82 in arm 80.Then, under the second chimerism, male 7 can produce sliding contact with the contact site of female end 3, thus male 7 is electrically connected to female end 3.Once achieve the second chimerism, in order to remove cloudy terminal shell 5 and the Qian He of male housing 8, arm 80 is distorted, thus the locking of unlock groove 82 and the second copulational protuberance 51.Thus, only need the releasing power that arm 80 is distorted.

On the other hand, when thrust being applied on the male housing 8 being in the first chimerism, cradle portion 81 is further moved in guiding groove 53c while directed along rib 53a, 53b of guide portion 53, and cradle portion abut with mosaic process 52.When in this condition further applied thrust time, cradle portion 81 elastic deflection with distortion, thus laterally expands outwardly about X-direction against thrust, and then rides over and will produce in the mosaic process 52 that abuts with rib 53a, 53b.Then, cradle portion 81 is slided in mosaic process 52 and rib 53a, 53b, and continues to move in lock slots 53c until whole hole portion 81a and be positioned in mosaic process 52.When whole hole portion 81a is positioned in mosaic process 52 in the above described manner, cradle portion 81 elastic deflection is with to internal strain, thus return to its initial position along the raised face (projected curved surface) of mosaic process 52 from lateral magnification situation, thus mosaic process 52 can be entrenched in hole portion 81a.As a result, cradle portion 81 is locked by mosaic process 52, makes cloudy terminal shell 5 enter the second nested position, that is, the second chimerism (state shown in Fig. 4 (a) to (c)) with male housing 8.

Synchronously produce the second copulational protuberance 51 with female end 3 and the electrical connection of male 7 to produce to engage with lock slots 82 and be entrenched in the state in lock bracket portion 81 in hole portion 81a with the state locking arm 80 and mosaic process 52, i.e. the second chimerism.Then, the second chimerism is utilized to maintain the electrical connection of female end 3 and male 7.When cutting off the electrical connection between female end 3 and male 7, the series of steps of the assembling process described so far sequentially should be performed in the opposite manner.

Thus, according to the connector 1 of this embodiment, the maximum load (load) when being connected together with male 7 by female end 3 can be reduced, and together with being fitted to male housing 8 when can improve together with cloudy terminal shell 5 is fitted to male housing 8 and by cloudy terminal shell 5 after the resistance to vibration of connector 1.
