In addition, as shown in Figure 6, in arm main body 25, the sliding space 31 being provided with and sliding for detection part 70 is rearward opened wide with the form be communicated with lock hole 28.Further, arm main body 25 is provided with stretches out to the inside and a pair guide portion 32 extended in the longitudinal direction from the two sides of sliding space 31.Two guide portion 32 form the en plaque marking off lock hole 28, and detection part 70 can slide on two surfaces up and down of two guide portion 32.And, as shown in Fig. 6, Fig. 7 and Fig. 8, there is a pair engaging portion 33 in the two sides of the sliding space 31 of arm main body 25 so that the form that the upper surface to two guide portion 32 is outstanding is projecting to the inside.

Then be described detection part 70, detection part 70 is made for synthetic resin, and is formed with the smaller size that can be installed in the sliding space 31 of arm main body 25.Specifically, as shown in Fig. 9, Figure 10 and Figure 11, detection part 70 has: the detection main body 71 of the en plaque extended in the longitudinal direction; The movement limiting portion 72 of ribbed, gives prominence to downwards at the Width central portion of the lower surface detecting main body 71 and extends in the longitudinal direction; And the directed section 73 of ribbed, stretch out to Width both sides in the bottom of movement limiting portion 72 and extend in the longitudinal direction.

Projecting on the upper surface of rearward end detecting main body 71 have operating portion 74.As shown in Figure 3 and Figure 5, when detection part 70 is positioned at initial position, operating portion 74 configures in the mode of the upper surface covering the rearward end of arm main body 25, by pressing this operating portion 74 downwards, lock arm 24 can be made to locking releasing direction flexural deformation.

As shown in Figure 10 and Figure 11, on the lower surface of leading section detecting main body 71, in the projecting restricted portion 75 of its Width central portion.As shown in Figure 5, when detection part 70 is positioned at initial position, limiting unit 75 abuts to the rear surface in the locked portion 27 of arm main body 25, thus restriction detection part 70 moves from initial position to detection position.In addition, as shown in Figure 1, when detection part 70 is positioned at detection position, limiting unit 75 abuts to the front surface in the locked portion 27 of arm main body 25, thus restriction detection part 70 returns movement from detection position to initial position.

As shown in Figure 9, projecting in the both side edges detecting main body 71 have a pair engaging portion 76.As shown in Figure 3, when detection part 70 is positioned at initial position, two engaging portions 76 abut to the front surface of two engaging portions 33 of arm main body 25, thus restriction detection part 70 is rearward deviate from.In addition, be provided with along with the mould for shaping directed section 73 passes and a pair through demoulding hole 77 at detection part 70.Two demoulding holes 77 become and arrange in the longitudinal direction in the substantially central portion of fore-and-aft direction detecting main body 71 and the form of slit-shaped that extends.

As shown in Figure 10, the front surface of movement limiting portion 72 is configured to, be positioned at the front surface of two directed sections 73 front and with the mode generally perpendicularly erected in the height direction slenderly extend by bearing surface 78.When detection part 70 is positioned at detection position, movement limiting portion 72 by bearing surface 78 to the bearing surface 49 of sticking department 48 terminating in the second housing 40, thus restriction detection part 70 forwards moves further.In addition, when looking view detection part 70 from master, being configured side by side in the direction of the width by bearing surface 78 front surface with guide portion 32 of movement limiting portion 72, in the height direction, being overlapped each other with the front surface of guide portion 32 by bearing surface 78 and configure of movement limiting portion 72.Further, movement limiting portion 72 be there is by the upper end of bearing surface 78 position relationship overlapped with limiting unit 75 in the height direction, main depending on visual angle in be hidden in the rear of limiting unit 75 and cannot be observed.

The structure of the connector of embodiment 1 is described above, then, is described the chimeric method of first, second housing 10,40 and the moving method of detection part 70.

First, second housing 10,40 chimeric before, detection part 70 is inserted into the sliding space 31 of the arm main body 25 lock arm 24 of the first housing 10 from rear and arrives initial position.As shown in Figure 3, on initial position, two engaging portions 76 of detection part 70 are configured to the front surface of two engaging portions 33 that can abut to arm main body 25, and as shown in Figure 5, can abut to the rear surface (engaged face 30) in locked portion 27 in the lock hole 28 that the limiting unit 75 of detection part 70 is configured to enter into arm main body 25, thus detection part 70 remains its movable confined state.

Then, first, second housing 10,40 is fitted.In chimeric process, slide in the directed face 29 in the locked portion 27 in the lock arm 24 of the first housing 10 on the sticking department 48 of the second housing 40, lock arm 24 flexural deformation centered by two fulcrum 26 thus, makes the leading section of arm main body 25 lift upward.When first, second housing 10,40 is correctly chimeric, lock arm 24 flexibly restores, and the engaged face 30 in locked portion 27 is in the face of the locking face 51 of sticking department 48, thus first, second housing 10,40 remains chimerism.Meanwhile, first, second terminal fittings 65,60 connects with correct status conducting.

Further, along with first, second housing 10,40 is correctly fitted together to, the sticking department 48 of the second housing 40 enters in the lock hole 28 of the first housing 10, and the limiting unit 75 of detection part 70 is pressed against sticking department 48 and deviates from upward from lock hole 28.Thus, allow detection part 70 to the movement of detection position.On the other hand, during before first, second housing 10,40 is correctly chimeric, the limiting unit 75 of maintenance detection part 70 enters into the state in lock hole 28, because which limit the movement of detection part 70 to detection position.Therefore, according to whether allowing detection part 70 to the movement of detection position, can learn whether first, second housing 10,40 is correctly fitted together to.

When first, second housing 10,40 is correctly chimeric, then, is forwards pressed into the operating portion 74 of detection part 70, makes detection part 70 move to detection position.To in the moving process of detection position, slide in two directed sections 73 of detection part 70 on the lower surface of two guide portion 32 of lock arm 24, and the arm main body 25 of detection part 70 is slided on the upper surface of two guide portion 32 of lock arm 24, thus guides the movement of detection part 70.Particularly, under the state that the limiting unit 75 detecting main body 71 is pressed against sticking department 48, detect the leading section flexural deformation of main body 71, now, abutted with two guide portion 32 by two directed sections 73, guarantee the smoothness of the flexure operation detecting main body 71.

As shown in Figure 1, when detection part 70 arrives detection position, detect the front surface that main body 71 elastic recovery and the limiting unit 75 of detection part 70 abut to the locked portion 27 of lock arm 24, thus restriction detection part 70 moves to the direction turning back to initial position.In addition, the leading section of the detection main body 71 of detection part 70 is configured to the below entering into covering wall 22.Therefore, even if the leading section of arm main body 25 will lift upward, abut to covering wall 22 owing to detecting the leading section of main body 71, the locking state of therefore prevent from unlocking immodestly arm 24 and sticking department 48.

In addition, on detection position, the bearing surface 49 being abutted to the sticking department 48 of the second housing 40 by bearing surface 78 of the movement limiting portion 72 of detection part 70, thus restriction detection part 70 moves to the front (direction away from initial position) of detection position.Now, the bearing surface 49 of sticking department 48 and movement limiting portion 72 be that face abuts shape and abuts by bearing surface 78 along the short transverse that the moving direction with detection part 70 is roughly orthogonal, the detection part 70 therefore arriving detection position supports exactly and is only limited further advance effectively at sticking department 48.And then, as shown in Figure 2, the part 79 of stretching out outside Width at the operating portion 74 of detection part 70 is connected to two engaging portions 33 of the arm main body 25 of lock arm 24 with half lock-out state, thus suppresses detection part 70 to move to the front of detection position in auxiliary mode.

As discussed above, according to embodiment 1, when detection part 70 is positioned at detection position, movement limiting portion 72 abuts with the sticking department 48 of the second housing 40, thus suppresses detection part 70 forwards to move further.Now, the other side side that movement limiting portion 72 abuts is arranged on the second housing 40 side, therefore, it is possible to simplify the structure of the first housing 10.Particularly, because the abutting object of movement limiting portion 72 is made up of the sticking department 48 of the second housing 40, therefore do not need the application specific architecture of the abutting object being provided as movement limiting portion 72 on the second housing 40 yet, the simplification of connector structure on the whole can be realized.

Further, movement limiting portion 72 and directed section 73 are configured to coincide with one another in the height direction, therefore, it is possible to suppress the height dimension of detection part 70, and then can suppress the height dimension of connector entirety.

And then, the bearing surface 49 of sticking department 48 erects configuration in the height direction, therefore when detection part 70 arrives detection position, movement limiting portion 72 slides and avoids riding this sticking department 48 on the bearing surface 49 of sticking department 48, and movement limiting portion 72 becomes the state being limited movement on the position abutted with the bearing surface 49 of sticking department 48 effectively.Now, even if the bearing surface 49 of sticking department 48 vertically erects in the height direction and configures, owing to being provided with directed face 29 on the front surface of lock arm 24, therefore obstacle can not be brought to the flexure operation of lock arm 24.
