【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a disassembled and assembled state of a first embodiment of the present invention. In FIG. 1, the rosette base 1 is integrally formed of synthetic resin, and has a substrate portion 11, a pair of supporting portions 12 and a connecting portion 13. The pair of supporting portions 12 are elastic flat plate-like members that are formed on the upper surface 11a of the substrate portion 11 so as to project. An approximately L-shaped hole 12a is formed in each of the supporting portions 12, and the jack housing 3 to be described later is provided. It can be pinched. Note that the hole 12a may be a recess instead of a hole as long as it fits into the protrusion 32 of the jack housing 3 described later. The connecting portion 13 is composed of a plurality of frames 13 a for mounting a plurality of terminal units 4 described later. The plurality of frames 13a are also projectingly provided on the upper surface 11a of the substrate portion 11. The rosette cover 2 is fitted and integrally formed with the rosette base 1, and covers the support portion 12, the connection portion 13, and a jack housing 3 described later. An opening 21 is formed in the rosette cover 2 corresponding to a plug insertion hole 31 of the jack housing 3 described later.

The jack housing 3 is formed of a synthetic resin in a case shape and has a plug insertion hole 31. The flexible lead wire 33 of the jack housing 3 is connected to the terminal unit 4 described later. Substantially L-shaped protrusions 32 are formed on both side surfaces of the jack housing 3, and the protrusions 32 can be fitted into the substantially L-shaped holes 12a of the pair of support portions 12 described above. Further, since both the protrusion 32 and the hole 12a are formed in a substantially L-shape, the fitting combination of the two can be changed to the opposite combination. By doing so, the direction of the plug insertion hole 31 becomes the direction of the plug insertion hole 31a shown by the chain double-dashed line. The plurality of terminal units 4 are for connecting the flexible lead wire 33 and a lead-in wire of a communication line such as a telephone, a fax machine, and a telex (not shown), and are adapted to be inserted into the frame 13a. There is. The composite CR part 5 is a composite element of a resistor and a capacitor, and is for a loop test of a communication line. The composite CR component 5 is connected to the lead-in wire side of the terminal unit 4.

FIG. 2 is a perspective view of the contact base 6 incorporated in the jack housing 3 described above. In FIG. 2, the contactor 61 is formed so that it can be connected to a plug (not shown) when the plug is inserted into the plug insertion holes 31, 31a of the jack housing 3. 3 is a partially cutaway front view of the first embodiment shown in FIG. 1, and FIG. 4 is a partially enlarged view of FIG. 3 and 4, the rosette base 1 and the rosette cover 2 are fitted together. Around the base plate portion 11 of the rosette base 1, a side portion 14 is formed perpendicular to the base plate portion 11 and is in contact with the inner side surface 22 of the rosette cover 2. A notch 23 is formed at the end of the inner side surface 22 (the end at the lower end in the figure). The cutout portion 23 is fitted to the side surface 11b of the substrate portion 11 of the rosette base 1.

Further, a gap 7 surrounded by the cutout portion 23 of the rosette cover 2, the substrate portion 11 and the side portion 14 of the rosette base 1 is an air reservoir. Since the gap 7 is formed in an annular shape as shown in FIG. 5, moisture is caused by capillary action from the portion in contact with the wall of the fitting portion of the rosette base 1 and the rosette cover 2 due to the capillary phenomenon. It is possible to prevent the inside of the rosette covered with the cover 2 from entering. On the lower surface 11c of the substrate portion 11 of the rosette base 1, a plurality of elongated base portions 15 are formed as shown in FIG. The thickness of the base portion 15 is about 1 mm, and the substrate portion 11 of the rosette base 1 is separated from the wall or the like by the thickness of the base portion 15. Therefore, air convects through the gap formed between the wall mounting surface / base portion 15 and the lower surface 11c of the base portion 11 of the rosette base 1, so that the temperature of the rosette base 1 does not follow the temperature of the wall. Since there is no difference between the temperature of the rosette base 1 and the temperature of the air, even if the wall is condensed, no condensation occurs inside the rosette base 1 and the rosette cover 2. The material of the rosette base 1 is synthetic resin, and the substrate portion 11, the side portion 14 and the base portion 15 are integrally formed. 16 is a screw hole for mounting. FIG. 7 is a perspective view showing an assembled state in which the rosette cover 85 of the second embodiment of the present invention is removed. In FIG. 7, the rosette base 81 has a substrate portion 81a and a side portion 81b, and the side portion 81b is formed so as to surround the periphery of the substrate portion 81a. The support portion 82 and the support portion 83 are provided so as to project from the substrate portion 81a, and substantially L-shaped holes 82a and 83a are formed in each of them. Note that these holes may also be recesses. The connecting portions 84a, 84b, 84c, 84d are respectively provided on the substrate portion 81a so as to project therefrom. The rosette cover 85 is formed so that it can be fitted to the base plate portion 81a and the side portion 81b of the rosette base 81, and has an opening portion 85a / corresponding to a plug insertion hole 86a / 87a of a jack housing 86/87 described later. It has 85b. The jack housings 86 and 87 have plug insertion holes 86a and 87a, respectively, and substantially L-shaped protrusions 86b and 87b are formed on both side surfaces thereof. The protrusions 86b and 87b are formed so that they can be fitted into the holes 82a and 83a of the support portions 82 and 83, respectively. Further, by changing the combination of fitting of the two protrusions 86b and the two holes 82a, the direction of the plug insertion hole 86a is perpendicular to the board portion 81a like the direction of the plug insertion hole 86a ₁ shown by the chain double-dashed line. You can switch to. Similarly, by changing the combination of fitting of the two protrusions 87b and the two holes 83a, the orientation of the plug insertion hole 87a can be changed to that of the board portion 81a like the orientation of the plug insertion hole 87a ₁ indicated by the chain double-dashed line. You can switch vertically. The above-mentioned holes of the pair of supporting parts of the rosette base and the projecting parts provided on both side surfaces of the jack housing are not limited to the above-mentioned L-shape, but may be substantially arc-shape, similar to the above-mentioned L-shape. Since it has the action of, a substantially arcuate shape may be used.
