The depth dimension of the coupling recess 33 in the vertical direction is substantially equal to the thickness dimension of the clamping portion 54 of the case 5, and the upper surface of each of the clamping portions 54 of the case 5 is substantially flush with the upper surface of the arm portion 32 of the base 3. Further, by the rearward facing inner surface of the coupling recess 33, the amount of displacement of the casing 5 with respect to the base 3, that is, the amount of displacement to the front is restricted, and the shell 5 is prevented from falling forward from the base 3. That is, the rearward facing inner surface of the coupling recess 33 constitutes a restriction portion in the technical solution. Further, in each of the coupling recesses 33, the locking convex portions 33a are protruded from the inner surfaces on the outer sides in the left-right direction, and the respective clamping portions 54 of the casing 5 are respectively provided inwardly in the left-right direction. The locked convex portion 54a is located on the rear side of the locked convex portion 54a by the locking convex portion 53a, and the amount of displacement of the casing 5 with respect to the base 3, that is, the amount of displacement to the rear is restricted, and the casing 5 is prevented from being The base body 3 is detached rearward.

The base portion of the nip portion 54 that is displaced downward along with the elastic deformation (near the vicinity of the joint portion of the side wall portion 53) is avoided.

By the use of the above-described configuration, the inventors succeeded in reducing the thickness of the plug 1 (the reduction in the size in the vertical direction described in the above description), and the connection in the state where the plug 1 can be connected to the socket. The overall height dimension (ie, stacking height) of the device is reduced from 1.5 mm to 0.8 mm in the conventional example.

Further, as shown in FIG. 5, it is also possible to provide contact which is protruded upward from the arm portion 52 of the case 5 and elastically contacts (contacts) with the contact portion 44 of the inner case 4, for example, by embossing. Projection 52a.

(Embodiment 2)

Since the basic configuration of the present embodiment is the same as that of the first embodiment, the description of the common portions will be omitted.

In the present embodiment, the specific configuration of the locking portion and the locked portion that prevent the casing 5 from falling rearward from the base 3 is different from that of the first embodiment. That is, instead of the locking convex portion 33a and the locked convex portion 54a, as shown in Figs. 6 and 7, the lower surface of each arm portion 32 of the base 3 (the upper surface in Figs. 6 and 7) is provided with a The outer side in the left-right direction is opened to accommodate the locking recessed portion 34 of the arm portion 52 of the case 5. In other words, in the present embodiment, each of the arm portions 52 of the case 5 is housed in the locking recessed portion 34 to prevent displacement of the case 5 with respect to the base body 3, that is, displacement in the front-rear direction, and each of the locking recesses 34 is formed. The rear surface facing the rear portion constitutes a restricting portion, and a portion of each of the arm portions 32 of the base body 3 on the rear side of the locking recess portion 34 constitutes a locking portion of the present invention, and each arm portion 52 of the casing 5 constitutes a technical solution. The card is locked.

Further, as shown in FIG. 8, the contact portion 44 of the inner casing 4 is not exposed to the lower side of the arm portion 32 of the base member 3, but is exposed to the coupling recess portion 33 at the upper side. That is, in the present embodiment, the arm portion 52 of the case 5 is not the arm portion 52 of the case 5, but the contact portion 54 is a contact portion that is in contact with the contact portion 44 of the inner case 4. In addition, it is needless to say that the arrangement of the contact portions 44 can be appropriately changed in the first embodiment and the present embodiment, so that, for example, in the first embodiment, the contact portion 44 of the inner casing 4 is on the base body 3 as in the present embodiment. The upper side is exposed, or in the present embodiment, the contact portion 44 of the inner casing 4 is exposed on the lower side of the base 3 in the same manner as in the first embodiment.

Further, on each of the arm portions 32 of the base body 3, guide projections 35 are protruded rearward from the outer end portions in the left-right direction. Each of the guide convex portions 35 is an inclined surface that is inclined downward toward the rear (the upper surface in FIGS. 6 and 7) and upward (that is, the smaller the size in the vertical direction is toward the rear).

In the present embodiment, when the case 5 is attached to the base 3, the case 5 is introduced in a state where the guide projections 35 of the base 3 are introduced between the arm portion 52 of the case 5 and the nip portion 54. Pushed in forward with respect to the base 3. Then, the upper surface of each arm portion 52 of the case 5 is in sliding contact with the lower surface (the inclined surface) of the guide convex portion 35, and the case 5 is elastically deformed so that the distance between the arm portion 52 and the holding portion 54 is changed. Large, and finally, as the elastic return of the casing 5, the arms 52 are respectively engaged in the locking recesses 34.

Here, in the elastic deformation during the above-described mounting process, the end portion on the side wall portion 53 side of the arm portion 52 of the case 5 is lower than the portion on the side of the cover portion 51 (in FIGS. 6 and 7). The amount of displacement of the upper part becomes smaller. Therefore, on the lower surface of the arm portion 32 of the base member 3, the portion on the rear side of the locking recessed portion 34 is inclined upward toward the outer side in the left-right direction (that is, the dimension in the vertical direction is made smaller toward the outer side in the horizontal direction). The above end portion of the arm portion 52 of the case 5 is opened.

By adopting the above configuration, the inventors have succeeded in achieving the reduction in thickness of the plug 1 (the reduction in the size in the vertical direction described in the above description).

The present invention has been described above with reference to the embodiments, but various modifications, changes and modifications may be made in the technical scope without departing from the scope of the invention. The technical idea of the present invention should be construed as exemplifying the present invention.
