Modern telephones connect the telephone housing, the machine string, and the handset cord by means of a modular jack/modular plug as disclosed in, for example, Japanese Utility Model Application No. 179279/1983 entitled "Connector Structure." This modular connector structure has the feature that the plug can be attached and detached from the modular jack with a single touch, and that it can be firmly connected by the action of the locking structure when it is inserted. As shown, modular jacks 2 and 3 for a machine string and a handset are fixedly arranged inside a telephone housing 1, and modular jacks 6 and 7 are attached to one end of a machine string 4 and a handset cord 5, respectively. The modular jacks 2 and 3 have a block shape as a whole, and are assembled and fixed to an assembly portion provided on the inner surface of the casing so as to fit into a plug insertion hole provided in the casing 1.

がある。 Various fixing structures for the modular jacks 2 and 3 have been proposed in the past.
A structure in which a notch is provided on the upper edge of the upper case 12 or the lower case 8 and the modular jack is inserted into the cut and held between the two cases 8 and 12; There is a structure in which an elastic engagement piece is used to lock onto a printed circuit board 13 that is incorporated into the housing 1.

However, although the fixing structure using the elastic engagement piece 10 allows the modular jack 2 to be assembled with a single touch, the engagement piece may be damaged or a modular jack having an engagement portion may be required, and the location where the elastic engagement piece 10 is provided may be difficult. In some cases, it becomes a so-called undercut, and when forming the lower case 8,
There was a problem that required slide die cutting. On the other hand, although the structure in which the upper case 12 and the lower case 8 are sandwiched and held has the simplest case shape, it is not practical because a part of the modular jack is exposed from the surface of the casing, spoiling the appearance. Moreover, the structure mounted on the printed circuit board 13 has the disadvantage that the elastic engagement piece is integrally provided on the module jack itself, and that the manufacturing of the mold is troublesome and expensive. In addition, when mounting on the printed circuit board 13, the plug is generally fixed to the edge of the printed circuit board so that the insertion direction is parallel to the surface of the printed circuit board, so there is a problem that the mounting position is severely restricted.
