Hereinafter, the adapter of invention is described with reference to accompanying drawing.Fig. 1 is the total structure being shown in the adapter according to inventive embodiment under the state (state before Qian He) that male housing separates with cloudy terminal shell.In the following description, the direction with three axles of right angle intersection shown in Fig. 1 is referred to as X-direction, Y-direction and Z-direction.In this case, Z-direction is corresponding to the chimeric direction (assembly orientation) of cloudy terminal shell with male housing, X-direction is corresponding to the direction that intersects at a right angle with chimeric direction (such as, horizontal direction), and Y-direction is corresponding to the direction (such as, vertical direction) intersected at a right angle with these directions.

As it is shown in figure 1, adapter 1 includes: cloudy terminal shell 5, forming multiple terminal accommodating chamber 4 in this moon terminal shell 5, female end 3 with contact site (not shown) is individually inserted into and is received in the plurality of terminal accommodating chamber 4；And the moon terminal shell 8, this the moon terminal shell 8 keeps multiple male 7, the plurality of male 7 and this contact site produce sliding contact to be connected to female end 3, and the busbar 6 that male 7 is connected to external conductor (as an example, earth conductor) is insert molded in this moon terminal shell 8.Then, in adapter 1, together with cloudy terminal shell 5 is fitted to male housing 8, so that female end 3 is electrically connected together with male 7.

Female end 3 is all formed as including: contact terminal portion 3b, comprise in this contact terminal portion 3b can the contact site of elastic deformation, 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 including: rectangular drum like accommodating chamber (hereinafter, referred to rectangular drum like portion), 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 it is assumed that material has elasticity, material to cloudy terminal shell 5 is not particularly limited, but in this embodiment, descriptions the moon terminal shell 5 is formed from a resin as an example.

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

The shaft constituted in the above described manner is by female end 3 pressing, thus before shaft engages with the lock hole generation in female end 3 being inserted in terminal accommodating chamber 4 (hereinafter, this state is referred to as half insert state) flexibly deflect with deformation, and after shaft engages with the lock hole generation in female end 3 being inserted in terminal accommodating chamber 4 (hereinafter, this state is referred to as suitable insert state), this shaft flexibly deflects to be deformed into its initial position.Specifically, under half insert state, shaft elastic deflection with deformation thus exits (as an example, downwards) from the rectangular drum like portion of terminal accommodating chamber 4.Then, under suitable insert state, position in lock hole is formed at female end 3, shaft elastic deflection is to be deformed to its initial position, hence into terminal accommodating chamber 4 rectangular drum like portion (as an example, the most upwards), so that shaft engages with the lock hole generation in female end 3.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 busbar 6 to highlight from busbar 6, thus to be attached thereto in being inserted into female end 3.Fig. 2 is the perspective view of the structure illustrating busbar 6.As in figure 2 it is shown, male 7 forms with busbar 6.In this case, male 7 is made up of the conductive material identical with the material of busbar 6.The end of male 7 is formed as entering the rectangular drum like portion of the terminal accommodating chamber 4 of cloudy terminal shell 5, is slidably connected with the contact site with 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, resin arm 80, resin connecting portion 83 and the resin cover 84 (with reference to Fig. 1) that will be described later are insert molded integratedly with busbar 6, 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, the male 7 both ends from the Y-direction of plate-shaped bus bars main part 6a highlight, and this busbar main part 6a extends along the X direction and extends into plate-like shape then towards the closure (direction shown in arrow A11 in Fig. 1) with female end 3.It addition, connecting portion 6b, 6c and the cradle portion 81 that will be described later are consecutively provided on busbar main part 6a, male 7 is connected to external conductor (as an example, earth 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 highlight from covering part 84 configured as above, thus are exposed to the outside (with reference to Fig. 1) of male housing.Fig. 2 illustrates that structure that each end that total of eight male 7 is arranged with roughly equal interval and four male 7 are arranged to from the Y-direction of busbar main part 6a extends is as an example.Certainly, male 7 should be correspondingly formed with the quantity of female end 3 being inserted in terminal accommodating chamber 4, and can at random set the quantity of male 7.It addition, annular seal member (such as, waterproof grommet etc.) is arranged between cloudy terminal shell 5 and male housing 8, thus prevent water from entering the connecting portion between female end 3 and male 7, this give adapter 1 with water proof structure.

As described above, adapter 1 is configured so that: when being entrenched togather with male housing 8 by the moon terminal shell 5, and female end 7 produces sliding contact to be connected with the contact site of female end 3.When it happens, together with cloudy terminal shell 5 is configured to male housing 8 at the first nested position and the second nested position to be fitted to (that is, with two stages).First nested position is that female end 3 is inserted in terminal accommodating chamber 4 and contact site is in the face of the position of male 7, and the contact site that the first nested position is set in male 7 and female end 3 produce sliding contact position before.Second nested position is set to the position of female end 7 and the contact site generation sliding contact of female end 3.In the following description, the state that cloudy terminal shell 5 and male housing 8 are parked in the first nested position is referred to as the first chimerism, and the state that cloudy terminal shell 5 and male housing 8 are parked in the second nested position is referred to as 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 is corresponding to suitable chimerism.By this way, adapter 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 will apply so that the load that female end 3 connects together with male 7 is divided into the load realizing the first chimerism and the load realizing the second chimerism, thus reduces for connecting the maximum load needed for terminal in the above described manner.

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 (by the direction shown in the arrow A11 in Fig. 1) being fitted to cloudy terminal shell 5, and cradle portion 81 is made of metal, and be continuously provided with busbar 6, upwardly extend chimeric side.

The arm 80 both sides from the X-direction of male housing 8 extend into plate-like shape towards the outer peripheral face (especially, the lateral surface 4d relevant with X-direction of the housing department 4c in rectangular drum like portion) of cloudy terminal shell 5.Arm 80 has groove portion (hereinafter, referred to lock slots) 82, and this groove portion 82 is formed along chimeric direction (Z-direction) extension of male housing 8 and cloudy terminal shell 5.In this embodiment, each sidepiece extension that two arms 80 are arranged to from the X-direction of male housing 8, and thus, total of four arm 80 is located towards the lateral surface 4d of housing department 4c and extends.That is, one group two arm 80 (80a, 80b and 80c in Fig. 1,80d) is arranged on each sidepiece in the X-direction of male housing 8, with constituted at the both ends in the X-direction of male housing 8 a pair such group.According to this structure, arm 80 both sides from the X-direction of male housing 8 on the chimeric direction (by the direction shown in the arrow A11 in Fig. 1) being fitted to cloudy terminal shell 5 extend, thus are maintained between arm 80 by the housing department 4c of cloudy terminal shell 5.It addition, on each sidepiece in the X-direction of male housing 8, the often end that these group of two arm is arranged in the Y-direction to male housing 8 all places an arm.Then, these arms 80 connect together via two connecting portions 83 at the both sides of male housing 8.That is, on the both sides of male housing 8, two arms 80 (such as, 80a, 80c) arranging end in the Y direction connect together via a connecting portion 83.Similarly, arrange two arms 80 (such as, 80b, 80d) at the other end in the Y direction to connect together via another connecting portion 83.Two connecting portions 83 extend each along X-direction, thus stretch (between 80a and 80c and between 80b and 80d) 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.

The cradle portion 81 sidepiece from the X-direction of busbar 6 extends into plate-like shape towards the outer peripheral face (specifically, from busbar main part 6a towards the lateral surface 4d the X-direction of housing department 4c) of cloudy terminal shell 5.That is, cradle portion 81 is continuously provided with busbar 6, 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 positions relative to cloudy terminal shell 5 and fixes simultaneously.As a result, such as, when the male being arranged on busbar 67 is inserted in female end 3, it is possible to limit between terminal and produce small slip, it is enable to limit male 7 and female end 3 and stands the abrasion of small slip.

In this embodiment, the single cradle portion 81 sidepiece from the X-direction of busbar 6 extends 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 so that arrange at the sidepiece that cradle portion 81 is positioned in the X-direction of male housing 8 between one group of two arm 80 (80a, the 80b shown in Fig. 1) at two ends in the Y direction.The docking section (Fig. 3 (c) and the extending end 81b shown in 4 (c)) of cradle portion 81 is formed as outward-dipping, thus become taper on chimeric direction (by the direction shown in the arrow A11 in Fig. 1), when making together with cloudy terminal shell 5 starts with male housing 8 to be fitted to and then 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 of cradle portion 81 is sized such that, and extending end 81b is positioned on chimeric direction (by the direction shown in the arrow A11 in Fig. 1) more prominent 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, the second copulational protuberance 51 produce the first copulational protuberance 50 engaged at the first nested position with the lock slots 82 that is formed in arm 80, engaging at the second copulational protuberance 51 with lock slots 82 generation in arm 80, the mosaic process 52 in the second joint place is embedded in the hole portion 81a being formed in cradle portion 81 and cradle portion 81 is directed to the guide portion 53 of mosaic process 52 is arranged on the moon terminal shell 5.

First copulational protuberance 50 is to be arranged to the mutually corresponding mode of lock slots 82 of arm 80 highlight from the lateral surface 4d of housing department 4c.In this embodiment, on each lateral surface 4d that two the first copulational protuberances are arranged in the X-direction of housing department 4c, thus highlight from this lateral surface 4d, and therefore, total of four the first copulational protuberance 50 is arranged to highlight from lateral surface 4d become approximately parallelepiped body shape.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, with constituted on each sidepiece in the X-direction of cloudy terminal shell 5 a pair such group.It addition, on each sidepiece in the X-direction of cloudy terminal shell 5, the often end that these one group two first copulational protuberances 50 are arranged in the Y-direction to housing department 4c all places first copulational protuberance.In the first copulational protuberance 50, docking section is formed obliquely towards lateral surface 4d, thus become taper on chimeric direction (by the direction shown in the arrow A12 in Fig. 1), when making together with cloudy terminal shell 5 starts with male housing 8 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 to be arranged to the mutually corresponding mode of lock slots 82 of arm 80 highlight from the lateral surface 4d of housing department 4c.In this embodiment, on each lateral surface 4d that two the second copulational protuberances are arranged in the X-direction of housing department 4c, thus highlight from this lateral surface 4d, and therefore, total of four the second copulational protuberance 51 is arranged on housing department 4c, thus highlights as approximately parallelepiped body 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, with constituted at two sidepieces in the X-direction of cloudy terminal shell 5 a pair such group.It addition, on each sidepiece in the X-direction of cloudy terminal shell 5, the often end that these one group two second copulational protuberances 51 are arranged in the Y-direction for housing department 4c all places second copulational protuberance.In the second copulational protuberance 51, docking section is formed obliquely towards lateral surface 4d, thus become taper on chimeric direction (by the direction shown in the arrow A12 in Fig. 1), when making together with cloudy terminal shell 5 starts with male housing 8 to be fitted to and then 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 are both positioned at the Z-direction about lateral surface 4d of lateral surface 4d on the side of male housing 8.Specifically, first junction surface 50 is positioned at relative on the nearside (corresponding with the first nested position) on the chimeric direction (by the direction shown in the arrow A12 in Fig. 1) being fitted to male housing 8, and the second copulational protuberance 51 is positioned at relative on the distally in identical chimeric direction (corresponding with the second nested position).That is, it is corresponding that the space between the first junction surface 50 and the second junction surface 51 that are arranged such 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 respectively provided at the two ends in the Y-direction of housing department 4c, and are limited to therebetween along the Z-direction of lateral surface 4d with the mutually corresponding space of relative movement distance in chimeric direction (Z-direction).

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

Mosaic process 52 is the projection in the hole portion 81a being entrenched at the second nested position in support 81, and therefore, it 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 the moon terminal shell 5 (specifically, 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, prominent 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 makes mosaic process 52 can be entrenched in hole portion 81a with the state of the edge of opening that mosaic process 52 is closely attached to hole portion 81a.Then, after mosaic process 52 is entrenched in hole portion 81a by this way, it is possible to limit between cloudy terminal shell 5 and male housing 8 any loosens, i.e. can improve the resistance to vibration of adapter 1, be enable to keep chimerism.That is, mosaic process 52 and hole portion 81a can give adapter 1 with slide lock (by locking) structure.Cradle portion 81 is made of metal, and therefore rigidity is high compared with the situation that it is formed from a resin, it is enable to improve loosening restriction (raising resistance to vibration) effect about in the vertical direction about lateral surface 4d (X-direction) outside going up except all directions (such as, Y-direction and Z-direction) on lateral surface 4d.

Guide portion 53 includes a pair hook rib 53a, 53b, this a pair hook rib is arranged along the chimeric direction (Z-direction) of cloudy terminal shell 5 and male housing 8 and extends parallel to, and guides this cradle portion 81 while cradle portion 81 being maintained between rib 53a, 53b.In other words, guide portion 53 is by hook rib 53a, 53b and the space that is limited between rib 53a, 53b (hereinafter, it is referred to as guiding groove) 53c composition, on the lateral surface 4d of housing department 4c, this hook rib 53a, 53b are positioned to face one another with defining predetermined space betwixt.In this embodiment, on the lateral surface 4d (that is, being provided with the lateral surface 4d of mosaic process 52) that rib 53a, 53b is arranged in the X-direction of housing department 4c.When it happens, rib 53a, 53b highlight from a lateral surface 4d while the distance of the width separated separately of each other in the Y-direction being substantially equal to support 81, and bending about on the rightabout of Y-direction, so that the distance between rib 53a, 53b narrows thereafter.Rib 53a, 53b are projected into the height of the thickness in the X direction being substantially equal to support 81 from lateral surface 4d.This is configured to limit the space making support 81 can be contained between rib 53a, 53b, and the space so limited constitutes 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, owing to cradle portion 81 is 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 loosening in the Y direction.Additionally, rib 53a, 53b should should be set to such size about Z-direction (cloudy terminal shell 5 and the chimeric direction of male housing 8): make under the first chimerism, the part being located close to extending end 81b of cradle portion 81 can be contained in guiding groove 53c, and under the second chimerism, cradle portion 81 include that being located close to the only about half of of extending end 81b can be contained in guiding groove 53c.

Herein, the example by the process they fitted together together with being fitted to male housing 8 by cloudy terminal shell 5 will be described.The assembling of terminal shell is performed: i.e. 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 is connectable to the state of male 7)；And make male 7 produce sliding contact, to realize another stage of the second chimerism that male 7 and female end 3 are electrically connected together with the contact site of female end 3.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 side view, and Fig. 3 (c) is along being intercepted by the line shown in the arrow A3 in Fig. 3 (b) and from the horizontal sectional view watched by the direction shown in arrow A3.It 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 side view, and Fig. 4 (c) is along being intercepted by the line shown in the arrow A4 in Fig. 4 (b) and from the horizontal sectional view watched by the direction shown in arrow A4.Note, Fig. 3 (a), 3 (c) and 4 (a), (c) eliminate female end 3 and is shown without female end 3.

In realizing the first chimerism, cloudy terminal shell 5 is positioned relative to male housing 8 so that the first copulational protuberance 50 is at a right angle with arm 80.Then, extending end and first copulational protuberance 50 of arm 80 produces and abuts.When applying predetermined thrust (acting on by the power on the direction shown in the arrow A11 in Fig. 1) in this condition, arm 80 elastic deflection is with deformation, thus laterally outward expand 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 is to be deformed inward, 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 joint hole 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 release cloudy terminal shell 5 and the Qian He of male housing 8, make arm 80 bend thus contact lock slots 82 and the locking of the first copulational protuberance 50.Thus, it is only necessary to make the contact force that arm 80 bends.

When applying thrust in the case of maintaining abuts with the first copulational protuberance 50 at the extending end of arm 80, cradle portion 81 is entrance 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 is positioned at the first nested position, cradle portion 81 be located close to being partially received in guiding groove 53c of its extending end 81b.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, it is applied to thrust be on the male housing 8 of the first chimerism, and the extending end of arm 80 and the second copulational protuberance 51 produce and abut.When applying thrust the most further, arm 80 elastic deflection is with deformation, thus laterally outward expands 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 is to be deformed inward, 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, the moon 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 release cloudy terminal shell 5 and the Qian He of male housing 8, make arm 80 distort, thus unlock groove 82 and the locking of the second copulational protuberance 51.Thus, it is only necessary to make the releasing power that arm 80 is distorted.

On the other hand, when being applied to thrust be on the male housing 8 of 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 abuts with mosaic process 52.When applying thrust the most further, cradle portion 81 elastic deflection is with deformation, thus laterally outward expands about X-direction against thrust, and then rides over and to produce in the mosaic process 52 abutted 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 is 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 to be deformed inward, thus return to its initial position from lateral magnification situation, so that mosaic process 52 can be entrenched in hole portion 81a along the raised face (projected curved surface) of mosaic process 52.As a result, cradle portion 81 is locked by mosaic process 52, makes cloudy terminal shell 5 enter the second nested position with male housing 8, i.e. the second chimerism (state shown in Fig. 4 (a) to (c)).

It is generated synchronously with the second copulational protuberance 51 with female end 3 and the electrical connection of male 7 and produces, with lock slots 82, the state engaged to lock arm 80 and mosaic process 52 is entrenched in hole portion 81a with the state of locking cradle portion 81, the i.e. second chimerism.Then, the second chimerism is utilized to maintain the electrical connection of female end 3 and male 7.When the electrical connection cut off between female end 3 and male 7, it should sequentially perform the series of steps of the assembling process described so far in the opposite manner.

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