Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a communication socket for plugging and connecting a lead wire plug attached to a communication device such as a telephone.

(Prior Art) Conventionally, as shown in the exploded perspective view of FIG. 5, in this type of communication outlet, a thin steel plate is used for the middle plate 21, and the left and right ends of the middle plate 21 are bent forward. Left and right folded parts 22L and 22R are formed, and a jack unit 2 integrally formed with a terminal block 23A is formed in the center of the middle plate 21.
3 is fixed with the two jack unit fixing screws 24L and 24R inserted from the back side of the middle plate 21, and the decorative frame 25 is attached to the jack unit 2.
Left and right folded portions 22L and 22R of the middle plate 21 are fitted into vertical grooves 25L and 25R formed at both left and right ends of the decorative frame 25, respectively.
In addition, there are two outer frame mounting screws 26U and 2 on the middle plate 21.
The outer frame 26 is attached by 6D. Furthermore, a surface plate 27 is attached to the outer frame 26 in a fitted manner.
Further, as shown in the figure, a surge suppressor 28 may be attached to the lower surface of the jack unit 23 in a tie-like manner.

Note that FIGS. 6, 7, and 8 are a left side view, a front view, and a rear view of the conventional communication outlet in an assembled state.

(Problems to be Solved by the Invention) In the conventional communication outlet described above, jack unit fixing screws 24L and 24R are used to attach the jack unit 23 to the middle plate 21. Therefore, when assembling a large number of communication outlets, there was a problem that it required a large number of assembly man-hours and a large number of parts, so we reduced the number of parts and the assembly man-hours to reduce costs. It was necessary to reduce it.

Therefore, the technical object of the present invention is to solve the above problem by fixing the jack unit to the middle plate without using jack unit fixing screws.

(Means for solving the problem) A technical means for solving the above problem is to connect a communication outlet to an outer frame made of synthetic resin that surrounds a rectangular space, and a A jack unit was fixed to the back side and the jack unit into which the plug attached to the communication equipment was inserted was placed in the center, while folded parts were formed at the left and right ends, and cut-out holes were formed in the left and right folded parts. An opening is formed in the center to fit the outer circumferential surface of the insertion port of the middle plate and the jack unit, and an opening is formed at the left and right ends with a dimension between the inner surfaces so that the inner plate can slide on the outer surface of each of the left and right folded parts of the middle plate. Left and right folded parts are formed, and on the inner surfaces of each of the left and right folded parts, a decorative frame is formed with a claw that fits into the notch hole formed in the left and right folded parts of the middle plate, and an insertion opening for the jack unit is exposed. In addition to forming an exposure hole to expose the outer frame, the outer frame has a surface plate that covers the rectangular space of the outer frame.

(Function of the invention) In the case of the communication outlet with the above configuration, with the jack unit placed at a predetermined position in the center of the middle plate, a decorative frame is placed over the jack unit, and both left and right folded portions of the decorative frame are placed on the middle plate. When the decorative frame is pushed from the surface while making surface contact with the left and right folded parts of the frame, the claws formed on the left and right folded parts of the decorative frame will fit into the notches of the middle board's folded parts, and The decorative frame and the middle plate are fixed with one touch, and the jack unit between the decorative frame and the middle plate is also automatically fixed. Therefore, the jack unit fixing screws that are required when fixing the jack unit to the middle plate as in the conventional communication outlet are not only unnecessary, but also the number of assembly steps is reduced.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is an exploded perspective view of a communication outlet 1 according to this embodiment. Figure 2 also shows communication outlet 1.
The left side view in the assembled state, Figure 3 is the front view,
FIG. 4 is a rear view.

In FIG. 1, the middle plate 2 is made of a thin steel plate treated with chromate plating, for example, like a conventional communication outlet, and has folded parts 2L and 2R folded back toward the front at both left and right ends. Furthermore, notch holes 2HL and 2HR are formed in the left and right folded portions 2L and 2R, respectively. Furthermore, outer frames 5 (described later) are provided at the upper and lower parts of the middle plate 2, respectively.
The screw holes 2U and 2D for fixing are tapped.

A jack unit 3 is arranged in the center of the middle plate 2 to connect a plug attached to a communication device (not shown). This jack unit 3 includes a jack 3A into which the plug is inserted, and a terminal block 3B connected to the contactor of the jack 3A.
are integrally molded, and a surge suppressor 3C is attached if necessary.

With the jack unit 3 placed in the center of the middle plate 2, a decorative frame 4 made of resin material connects the jack 3A of the jack unit 3 to the opening 4A.
It is placed over the jack unit 3 in a state where it is fitted. The decorative frame 4 has the above-mentioned opening 4A formed in the center, and has right-angled folded parts 4 at the left and right ends.
L and 4R are formed, and furthermore, this folded part 4
A plurality of claws 4N are formed on L and 4R.
Each of the claws 4N has folded parts 4L and 4R.
and the folded portion 2L of the middle plate 2.
When the decorative frame 4 is pressed from the surface with surface contact between the outer surfaces of the holes 2 and 2R, the notch holes 2
It is designed to fit into HL and 2HR, and to integrally fix the decorative frame 4 and the middle plate 2. Therefore, at the same time that the decorative frame 4 and the middle plate 2 are fixed, the jack unit 3 held between the decorative frame 4 and the middle plate 2 is also fixed integrally. In this state, the outer frame 5 is fixed to the intermediate plate 2 by screwing the outer frame mounting screws 5U and 5D into the screw holes 2U and 2D. Thereafter, the claws 6A to 6F of the surface plate 6 enter the corresponding notches 5A to 5F of the outer frame 5, and are hooked and fixed to the notches 5A to 5F.

As described above, since the jack unit 3 is fixed to the intermediate plate 2 in a one-touch manner using the decorative frame 4, assembly is extremely easy and can be completed in a short period of time.

(Effects of the invention) As described above, according to the invention, since the jack unit can be fixed to the middle plate without using jack unit fixing screws, the number of parts of the communication outlet can be reduced, and the number of parts for the communication outlet can be reduced. This has the effect of reducing the number of man-hours required and the cost of communication outlets.
