Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a housing of a key telephone main unit that performs switching connections and the like.

Structure of the conventional example and its problems In Figs. 1 to 3, the main device housing has a top plate 3, a front plate 4, and a front plate 4, each having a bent peripheral portion.
Assemble the bottom plate 5, the two side plates 6, and the back plate 7 into a box shape as shown in FIG.
The cable 1b was introduced into the housing through the connector 2, or the cable 1b was introduced into or led out through the connector 2, which was also attached to the side plate 6. For this reason, the connector 2 is located outside the device, and the exit of the cable from the device is at the top of the device, resulting in problems such as the cable getting stuck and the placement position being restricted.

Purpose of the invention The object of the invention is to eliminate the drawbacks of the above-mentioned conventional example, and to provide a housing with a strong structure without exposing the cable input/output portion to the outside.

Structure of the Invention In order to achieve the above object, the present invention folds both side plates of a box-shaped case inward to increase the strength of the case, and inserts the folded side plates from the front.
A second side plate is provided that covers the side plate from the outside by being bent into a U-shape, and the cable is raised from below the space formed inside the second side plate, and the cable is routed through the introduction part provided at the top of the side plate. It is configured to be introduced into the body.

DESCRIPTION OF EMBODIMENTS The present invention will be described below by way of an embodiment thereof with reference to the drawings. In Figure 4, 11 is a cable, 13
is a top plate made of a rectangular flat plate. Reference numeral 14 denotes a front plate, which is a flat plate bent into a U-shape and provided with folded portions (second side plates) 14a and 14b. Reference numeral 15 designates a bottom plate, in which opposite ends of the flat plate are bent upward to provide folded portions 15a and 15b, and the remaining two sides are bent twice to provide a downwardly U-shaped folded portion for holding. There is. Reference numeral 16 denotes a back plate, and a folded part 16a facing inward is provided at the upper part of the flat plate. Reference numeral 17 denotes a side plate (first side plate) of the same shape, and L-shaped folded portions 17a and 17b each bent outward are provided at the front and rear ends thereof. Also side plate 1
One upper part of 7 has a notch 18c.
Reference numeral 18 is a cable holding fitting, and reference numeral 19 is a board.

With the above configuration, the folded portions 15a, 1 of the bottom plate 15
5b, and both ends of the back plate 16 are locked to the folded portions 17a of the side plate 17 as shown in FIG. A box-shaped casing is constructed by inserting and fixing the top plate 13 on both outer sides of the side plate 13, covering the upper part including the folded parts 17a and 17b, and fixing it to the folded part 16a. A space 20 having a rectangular cross section is formed between them. On the other hand, cable 11
For example, the notch 17 provided at the top of the side plate 17
It is connected to the board 19 stacked inside the casing via cable c, and is fixed to prevent it from coming off by a cable holding fitting 18 fixed to the side plate 17. As for the method of configuring the introduction part of the cable into the housing, the cable may be directly connected to the board 19, or other cable connectors, adapters, etc. may be used.

Effects of the invention As explained above, according to the invention, both ends of a single flat plate are bent into a U-shape, and cables can be inserted and removed using the U-shaped front plate that covers the side plates and the front and sides. Since a space is formed for this purpose, the cable can be lowered from the bottom of the space, increasing the degree of freedom in the arrangement position of the device. Additionally, since the side plates are bent into a U-shape, the strength of the casing can be increased. Furthermore, there is an advantage that a cable support or connector can be freely selected and attached to the upper part of the space.

Claims (1)

[Scope of utility model registration request] a bottom plate having folded parts at both ends;
Each of the side plates has a lower end portion locked to the folded portion, and has an L-shaped outward folded portion at the front end and rear end, and the above-mentioned side plate formed at the rear end of each of these side plates. A box with an opening on the front is formed by the back plate which is secured to the L-shaped folded parts, and the front of the box has folded parts at both ends, and these folded parts have folded parts. Therefore, a U-shaped front plate covering the outside of each of the side plates is attached to form a space for raising a cable between the folded part of the front plate and the side plate, and a cable is raised from below into the space. A casing of a key telephone main device configured such that an inserted cable is introduced into the box body through a notch formed at an upper end of the side plate.
