Next, the operator attaches the cap packing 81 to the female housing 3 . Next, the operator attaches the female cap 8 to the female housing 3 .

Next, the worker removes the female housing 3 from the jig, and then inserts the male terminal 140 into the male terminal accommodating space 4s1 of the female terminal 4 through the holder opening 6h. At this time, the operator separately moves the female holders 6 perpendicular to the female terminals 4, and inserts the male terminals 140 into the male terminal accommodating spaces 4s1. Then, the operator accommodates the male terminal 140 in the male terminal accommodating space 4 s 1 of the female terminal 4 to set the male terminal accommodating state, and electrically connects the female terminal 4 and the male terminal 140 via the connecting member 5 .

In the male terminal accommodating state, as shown in FIG. 3, the packing accommodating space 3s2 is located inside the female housing 3 radially facing the housing-side packing restricting surface 3f1 and the holder-side packing restricting surface 6f2 facing each other in the axial direction X. and the outer peripheral surface of male housing 130 .

In the male terminal accommodating state, the connecting terminal accommodating space includes a female terminal side connecting member restricting surface 4f1 and a holder side connecting member restricting surface 6f3 facing each other in the axial direction X, and an inner peripheral surface of the female terminal 4 and a male terminal facing each other in the radial direction. and the outer peripheral surface of the terminal 140 .

Next, the worker covers the female housing 3 with the shield shell 2 . Finally, the operator inserts the tip of the first bolt Bo1 into the first bolt hole of the shield shell 2, and then screws the first bolt Bo1 into the first screw hole Nu1 to attach the shield shell 2 to the substrate 201. to form the female connector 1 and the connector device 100 . In this state, female connector 1 and male connector 101 are fitted together, and female terminal 4 and male terminal 140 are electrically connected.

The female connector 1 according to this embodiment has the following configuration. The connecting member 5 is positioned between the female terminal side connecting member restricting surface 4f1 and the holder side connecting member restricting surface 6f3 facing each other in the axial direction X when the male terminal 140 is accommodated in the male terminal accommodating space 4s1. The movement in the axial direction X is restricted by . When the male terminal 140 is accommodated in the male terminal accommodating space 4s1, the packing is located between the housing-side packing restricting surface 3f1 and the holder-side packing restricting surface 6f2 facing each other in the axial direction X. movement is restricted. Suppose that the female connector 1 is provided with a first holding member that holds the connection member 5 in cooperation with the female terminal 4 and a second holding member that holds the packing in cooperation with the female housing 3. , the number of parts increases. On the other hand, the holder of the female connector 1 according to this embodiment holds the connecting member 5 in the axial direction X in cooperation with the female terminal 4 and holds the packing in the axial direction X in cooperation with the female housing 3. do. As a result, the female connector 1 according to this embodiment can be used also as a holder for holding the connecting member 5 in the axial direction X and for holding the packing in the axial direction X, thus increasing the number of parts. can be suppressed.

The connector device 100 according to this embodiment has the following configuration. The holder and the female terminal 4 have a movement permitting portion MV that allows the holder to move in the radial direction with respect to the female terminal 4 in a state where the locking portion 624 and the locking receiving portion 431 are locked. In the connector device 100 according to the present embodiment, since the female housing 3 is formed by connecting a plurality of female terminal accommodation space forming portions 31, the distance between the plurality of female terminals 4 in the orthogonal direction is constant. Moreover, in the connector device 100 according to the present embodiment, since the male housing 130 is formed by connecting the plurality of male terminal accommodation space forming portions 131, the distance between the plurality of male terminals 140 in the orthogonal direction is constant. be. If a plurality of holders are formed by connecting them in the orthogonal direction, it is impossible to change the intervals between the plurality of holder openings 6h in the orthogonal direction. It takes time and effort. On the other hand, in the connector device 100 according to the present embodiment, in a state in which the locking portion 624 and the locking receiving portion 431 are locked, there is a movement-allowing mechanism that allows the holder to move in the radial direction with respect to the female terminal 4 . Since it has the portion MV, each holder opening 6h can be moved in the direction orthogonal to the female terminal 4. As shown in FIG. As a result, in the connector device 100 according to the present embodiment, the holders can be individually moved by the movement permitting portion MV, and the intervals between the plurality of holder openings 6h can be changed in the radial direction. Workability for inserting the terminal 140 can be improved.

It should be noted that the female connector 1 according to the above-described embodiment has been described as a shield connector. However, the female connector 1 according to this embodiment may be formed as a connector without the shield shell 2 .

Moreover, the female connector 1 according to the above-described embodiment has been described as having two female terminals 4 . However, the female connector 1 according to this embodiment is not limited thereto. For example, the female connector 1 according to this embodiment may have three or more female terminals 4 .

Furthermore, in the female connector 1 according to the above-described embodiment, the female terminal 4 is provided with the locking receiving portion 431 and the female holder 6 is provided with the locking portion 624 . However, the female connector 1 according to this embodiment is not limited thereto. For example, in the female connector 1 according to this embodiment, the locking portion 624 may be provided on the female terminal 4 and the locking receiving portion 431 may be provided on the female holder 6 .

Further, in the movement permitting portion MV according to the above-described embodiment, the radius 624R from the axis XL to the locking portion 624 and the radius 431aR from the axis XL to the bottom portion 431a of the locking receiving portion 431 are the same in the orthogonal direction. explained something. However, the movement permitting part MV according to this embodiment is not limited thereto. For example, in the movement permitting portion MV according to the present embodiment, even if the radius 624R from the axis XL to the locking portion 624 in the orthogonal direction is smaller than the radius 431aR from the axis XL to the bottom 431a of the locking receiving portion 431, good. The movement permitting portion MV configured as described above provides a clearance between the tip of the locking receiving portion 431 and the bottom portion 431a of the locking receiving portion 431 in the orthogonal direction so that the locking portion 624 and the locking receiving portion 624 are separated from each other. The female holder 6 is allowed to move in the radial direction with respect to the female terminal 4 in the state where the portion 431 is locked.
