[Embodiment] As shown in FIG. 1, a case 1 includes a body 10 on which components constituting a modular jack are mounted,
It is formed by joining the cover 20 to be fitted to the cable and has a size equivalent to two large square modules of wiring equipment specified in JIS standard, and a metal specified in the industrial standard of the wiring equipment industry association. The mounting portion is formed so that it can be attached to the mounting frame made of synthetic resin or the mounting frame made of synthetic resin. These mounting frames are adapted to be mounted on an embedded box such as a switch box. The mounting portions are formed on both side surfaces of the cover 20, respectively.For the metal mounting frame, protrusions of the metal mounting frame are provided in a pair of locking holes 21 formed on the left and right side surfaces of the cover 20, respectively. For the synthetic resin mounting frame, four locking claws 22 protruding from both sides of the cover 20 are inserted into the holding holes formed in the synthetic resin mounting frame. Combined by doing. Further, a decorative plate used for wiring equipment can be attached to these attachment frames, and the attachment frames can be covered. Thus, the cover 20 has dimensions corresponding to two modules of a wiring device.

On the upper surface of the cover 20, at a position corresponding to each module, an insertion hole 23 into which a modular plug can be inserted,
A receiving-side connector A to which an insertion-side connector for a coaxial cable can be connected is formed. The receiving connector A is a cover
At the center of the recess 24 that sinks from the upper surface of 20, a cylindrical platform
25 is formed in a projecting shape, an outer conductor 26 is provided along the outer peripheral surface of the protruding table 25, and a cylindrical inner conductor 27 is formed along the inner peripheral surface of the protruding table 25. Is installed.
At a portion corresponding to the receiving side connector A, a box 32 having a rectangular tubular shape and an open lower surface is extended on the lower surface of the cover 20,
In the box 32, a printed circuit board 33 connected to the outer conductor 26 and the inner conductor 27 is provided. Box 32
Are formed so that at least the inner peripheral surface has conductivity, and assembly projections projecting from both side surfaces of the box 32 are provided.
32a is also formed to have conductivity. Four contact springs 35 are electrically connected to the ground pattern of the printed circuit board 33 connected to the outer conductor 26, and the contact springs 35 elastically contact the inner peripheral surface of the box 32. The inner peripheral surface of the box 32 is grounded to the ground pattern of the printed circuit board 33, so that the box 32 functions as a shield case. On the lower surface side of the printed circuit board 33, a pair of holding springs 36 connected to the inner conductor 27 is mounted, and a frame 37 having a pair of cylindrical portions 37a respectively corresponding to the both holding springs 36 is a box 32. Will be installed inside. The frame 37 is held by a shield plate 38 that covers the lower surface of the box 32. The shield plate 38 includes a rectangular frame-shaped assembly piece 38 a
It is coupled to the box 32 by being swaged so as to be hooked on the assembly projection 32a protruding from the side surface of the box. Thus, simultaneously with the mechanical connection between the box 32 and the shield plate 38, the electrical connection is also performed, and the shield plate 38 is connected to the ground pattern of the printed circuit board 33. A pair of left and right holding pieces 38b project downward from the shield plate 38, and a holding plate 39 is rotatably held between the two holding pieces 38b. That is, the holding plate 39 is provided with the hooking piece 39a protruding therefrom. By inserting the hooking piece 39a into the holding piece 38b, the holding plate 39 is attached to the shield plate 38 so as to be freely opened and closed. This holding plate 39 is
It is fixed to the shield plate 38 by 34.

Therefore, with the fixing screw 34 removed, the inner conductor of the coaxial cable is inserted into the holding spring 36 through the cylindrical portion 37a, and the outer conductor of the coaxial cable is sandwiched between the shield plate 38 and the holding plate 39 to fix the fixing screw 34. If it is tightened, the coaxial cable is connected to the receiving connector A.

By the way, at the portion where the insertion hole 23 is formed, the cover 20
Hooks 28 project downward from the left and right side edges of the lower surface of the device. The hooks 28 are fitted in fitting holes 11 formed at both right and left ends of the body 10 to connect the body 10 to the cover 20. The body 10 is formed into a shape having a terminal storage chamber 13 and a jack storage chamber 14 inside by a partition rib 12, and three terminal storage chambers 13 are formed on each of the left and right sides. Terminals 15 are respectively mounted in the respective terminal storage chambers 13, and each terminal 15 is disposed in the terminal frame 15a and a terminal frame 15a formed in a substantially U-shape. Lock spring 15b with spring force toward the peripheral surface
And formed. That is, an electric wire introduced from the lower surface side of the body 10 is sandwiched between the terminal frame 15a and the locking spring 15b, and has a structure known as a quick connection terminal. A release button for removing the electric wire held by the terminal 15 from the terminal is formed integrally with the body 10. A modular insert 16 is provided in the jack storage room 14. The modular insert 16 has lead pieces 16a on both left and right sides of the main body 26d, and has a contact spring 16b at the center thereof, which is electrically connected to each lead piece 16a. The lead piece 16a is
It has a pressure contact slit 16c opened downward, and by press-fitting a connection piece 15c protruding from the terminal frame 15a into the pressure contact slit 16c, the contact spring 16b and each terminal 15 are connected. It is. Contact spring 16b
The middle frame 17 is fitted to the portion where is formed. A guide frame 17a into which the modular plug can be introduced is formed in the middle frame 17, and guides each contact of the modular plug so as to contact the corresponding contact spring 16b. Further, a pair of doors 1 is provided between the guide hole 17a of the middle frame 17 and the insertion hole 23 of the cover 20.
A door 18 composed of 8a and 18b is provided, and the insertion hole 23 can be opened and closed.

With the above configuration, if the modular plug is inserted into the insertion hole 23 with the door 18 opened, the contact of the modular plug is connected to the contact spring 16b. Since the contact spring 16b is connected to the terminal 15 via the lead piece 16a, if a telephone line is connected to the terminal 15, the modular plug and the telephone line can be connected. Thus, the modular jack B is formed.

[Effect of the Invention] As described above, the present invention has a mounting portion that can be engaged with a standardized mounting frame mounted on an embedding box, and provides a rectangular module of two standardized wiring devices. On the front surface of a case having equivalent dimensions, a receiving connector to which an insertion connector to which a coaxial cable is connected can be coupled, and a modular jack to which a modular plug for a telephone line can be coupled, are provided side by side. Since the receiving side connector to which the insertion side connector to which the coaxial cable is connected can be connected and the modular jack to which the telephone line modular plug can be connected in one case, the coaxial cable and the telephone line can be connected. There is an advantage that pre-wiring can be performed at one place. In addition, by engaging the mounting portion of the case with the mounting frame and mounting the case to the mounting frame, both the receiving connector and the modular jack can be mounted on the mounting frame in one operation,
The mounting operation of the receiving connector and the modular jack to the mounting frame can be easily performed. Also, since the case has dimensions equivalent to two square modules of the wiring device, it can be mounted on the mounting frame for the wiring device, and various decorative plates for the wiring device can be used, and By using a module for three modules as a mounting frame, a power outlet for modularized power lines is arranged in the space left for one module, and the information line and the power line are securely connected. There is an advantage that it is also possible to dispose them in the same place in an insulated state.
