Abstract

PURPOSE:To assemble in a good shape in a simple composition by providing a plug insertion port at the lower half side of a front side cover, and composing the lid of the insertion port with one slide piece of a self-weight dropping type. CONSTITUTION:A wall socket 1 is composed of a front side cover 5, a middle case 6, and a main body case 7. A slide piece 3 slides on a slide surface 13 between a pair of guides 2 provided at the middle case 6 along the guides. At the front side cover 5, four connecting arms 8 are provided. The connecting arms 8 are geared with the projections 10 of the main body case 7 through the holes 9 provided to the middle case 6. As a result, the front side case 5, the middle case 6, and the main body case 7 are assembled and fixed integrally. When the wall socket 1 is connected, the projections 4 of the slide piece 3 is pulled up with fingers to open the insertion port 2, and the plug at the telephone side is inserted. Consequently, the plug and the connection terminal inside the wall socket main body are connected and made operative. When the plug is pulled out, the slide piece 3 closes the insertion port 2 by its own weight.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plug-in type connection device such as a modular outlet for a telephone, and particularly to a cover structure of a plug insertion port thereof.

[Prior Art] As a connection device for a telephone, a modular outlet for a telephone has been commercialized, which allows the telephone to be stored or moved by inserting a plug when in use and removing the plug when not in use. In such a modular outlet, a plug insertion opening is provided on the front side of the outlet body, and this insertion opening is provided with a sliding lid for dustproofing and internal protection when not in use. In conventional modular outlets,
A plug insertion opening is provided at a slightly lower center of the front of the outlet body, and a self-gravity-dropping type lid that slides up and down is attached to open and close the insertion opening. Due to the vertical dimension of the electrical outlet, this conventional sliding type lid has a two-stage structure by combining two sliding pieces.

[The invention attempts to solve i! [Problem] In the plug insertion port structure of the conventional modular socket for telephones, the cover of the insertion port is composed of two sliding pieces, which results in a large number of parts, a complicated structure, and troublesome assembly work. , which was undesirable because it also increased the cost.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a connecting device having a sliding type lid structure that is simple in structure and easy to assemble.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the connection device according to the present invention, an insertion opening for a connection terminal is provided on the lower half side of the front cover of the device body, and upper and lower ends are provided on the inner surface of the front cover. A self-drop type lid is attached to open and close the insertion opening, which is composed of a single slide piece that slides in the direction of the insertion opening.

[Function] The single slide piece that makes up the lid of the insertion port slides between the upper and lower halves of the front cover of the device body, and when it falls under its own weight, it covers the insertion port and lifts it upward. In this position, the insertion port is completely opened.

[Embodiment] FIGS. 1 and 2 are a front view and a perspective view, respectively, of a modular outlet for a telephone according to the present invention, and FIG. 3 is an exploded perspective view thereof. A plug insertion opening 2 is provided in the lower half of the front cover 5 of the outlet 1. A single slide piece 3 that can be slid up and down is attached to the inner surface of the front cover 5. When the slide piece 3 is pulled up from the dotted line position to the dotted line position via the lower projection piece 4 of the slide piece 3 as shown by arrow A (FIG. 1), the insertion port 2 is completely opened. If the slide piece 3 is released, it will fall under its own weight and completely close the insertion port 2 at the lower end position.

Such an outlet 1 includes a front cover 5, an inner case 6, and a main body case 7. Slide piece 3
slides on a sliding surface 13 between a pair of guides 12 (FIG. 3) provided in the inner case 6 along the guides. The front cover 5 is provided with four connecting arms 8. Each connection @8 is connected to a protrusion 10 of the main case 7 through a hole 9 provided in the inner case 6.
engage with. Thereby, the front cover 5, the middle case 6, and the main case 7 can be assembled and fixed as one unit.

When connecting an outlet, pull up the protrusion 4 of the slide piece 3 with your finger to open the insertion slot 2, and then insert the plug (
(not shown). As a result, the plug is connected to the connection terminal (not shown) inside the outlet main body case, and the telephone becomes usable. When the plug is pulled out, the slide piece 3 is processed by its own weight and closes the insertion opening 2.

[Effects of the Invention] As explained above, in the adhesive device according to the present invention, the plug insertion opening is provided on the lower half side of the front cover, and the lid of this insertion opening is constituted by one slide piece that falls under its own weight. Therefore, a simple structure and easy-to-assemble outlet structure can be obtained, and the sliding opening/closing operation is smooth and reliable, and the effect of preventing dust from adhering to the internal connection terminals when not in use is reliably achieved.

Note that the present invention is not limited to modular sockets for telephones, but can also be applied to connection devices that have a plug-in plug insertion port and have a cover for dustproofing and internal protection at the insertion port. be.

Further, although the embodiment is a module-sized outlet with one insertion port, the present invention is not limited to this, and can be used in combination with other devices as a large rectangular multiple-use device, or as a connecting device with multiple plug insertion ports. Applicable.
