Description

[Detailed description of the invention] [Summary] It has an inverted convex hole with an insertion part and a fixing part, and the insertion part of the wall hanging bracket fixed to the wall has a tapered part with a T-shaped cross section placed on the bottom of the box. To securely attach a terminal device to a wall with a simple structure in which a fixing protrusion is inserted, pressed, and slid in the direction of engagement.

[Industrial application field]

The present invention relates to a terminal device widely used in various electronic devices.

Recently, there has been an increasing demand for installing various terminal devices on walls, particularly in the fields of communication, information processing, and the like.
Therefore, there is a need for a structure that facilitates the attachment and fixation of various terminal devices installed on walls.

[Conventional technology]

The structure of the terminal device that has been widely used in the past is the 4th structure.
As shown in the figure, a fastening protrusion 1-0 having a T-shaped cross section with a constant length and a dimension a on the inside facing the bottom surface is large enough to match the plate thickness b of the wall hanging bracket 2 shown in FIG. As shown in FIG. 2, the two terminal devices 1 are inserted into an insertion portion 2-1 large enough to allow insertion of the above-mentioned locking protrusion 1-0, and an engagement portion 2-1 large enough to allow the base portion to slide. A reverse convex hole having a portion 2-2 is provided so as to face the locking protrusion 1-0, and combined with a wall hanging bracket 2 bent into a convex shape, a bolt 3 is inserted as shown in the installation side view of FIG. Fix the wall hanging bracket 2 to the wall with By moving the wearing protrusion 1-0 to the engaging part 2-2,
The terminal device is held by the wall hanging fitting 2 due to the gravity of the terminal device housing various electrical components and the contact between the base of the engaging protrusion 1-1 and the engaging portion 2-2.

[Problem that the invention attempts to solve]

The problems with the conventional terminal devices explained above are:
Insert the locking protrusion into the insertion part and press the bottom against the wall bracket, and then slide it in the engagement direction to hold it, so the dimension between the bottom and the inside of the opposite locking protrusion is Due to manufacturing variations, etc., a gap is provided in advance with respect to the thickness of the wall-mounting fitting, and there is a risk that the attached terminal device may vibrate or come off from the wall-mounting fitting due to external force. This is a cause of hindering the stability and reliability of the device.

The present invention aims to provide a terminal device that can be easily and reliably attached to a wall in view of the above-mentioned circumstances.

[Means for solving problems]

As shown in Fig. 1, the inner side facing the bottom surface 1a becomes a sloped surface 1b from one end, and sloped protrusions 1-2 are arranged on both sides, a part of which is sized to be able to fix a wall-hanging metal fitting. This problem is solved by the terminal device 1 in which at least one locking protrusion 1-1 having a T-shaped cross section of a certain length is arranged.

[Effect]

That is, in the present invention, as shown in the installation side view in FIG.
Thereafter, by sliding in the direction of arrow B and moving to the engaging portion 2-2, the inclined protrusion 1-2 provided inside the engaging protrusion 1-1 becomes more inclined than the end in the sliding direction. Therefore, it can be easily moved and the engaging portion 2-2
Since the minimum interval formed by the inclined protrusions 1-2 is smaller than the thickness of the wall hanging bracket 2, the elasticity of the engaging protrusions 1-1 causes the inclined protrusions 1-2 to close at least two places. 2 and the bottom of the terminal device.

Therefore, it is possible to facilitate the movement of the terminal device 1 in the direction of the engaging portion 2-2, and it is possible to improve the stability and reliability of the device by eliminating any gap between the terminal device 1 and the wall-mounted fitting.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a bottom perspective view of the terminal device according to this embodiment.

As shown in the figure, on the inner side facing the bottom surface 1a on both sides of a T-shaped cross-sectional shape having a certain length, half from the end in the sliding direction of arrow A becomes an inclined surface 1b.
The other half of the attachment protrusion 1-1 has an inclined protrusion 1-2 that is parallel to the bottom surface 1a and has a size that allows the thickness of the wall-hanging metal fitting to be press-fitted. Terminal device 1 made of synthetic resin with two pieces arranged at a constant interval on a line
mold.

Next, as shown in FIG.
An inverted convex hole is formed by combining an insertion portion 2-1 large enough to allow insertion of the locking projection 1-1, and an engaging portion 2-2 large enough to allow the base of the locking protrusion 1-1 to slide into the hole.
The wall hanging fittings 2 are bent and provided at the same intervals as the pitches of the fastening protrusions 1-1.For example, they are formed from a rolled steel plate to a predetermined size strong enough to hold a terminal device equipped with various electrical components, and the surface is coated with anti-rust coating. Manufacture metal fittings with a tack.

As shown in the installation side view of FIG.
1, insert the engaging protrusions 1-1 of the terminal device 1, press the bottom surface, and slide in the direction of arrow B until it hits the side end surface of the engaging part 2-2. 1-2 and the bottom of the terminal device 1
It can be attached to the wall hanging fitting 2 by sandwiching it with a.

[Effect of idea]

As explained above, according to the present invention, a terminal device can be removably attached to a wall-mounted metal fitting with an extremely simple structure, and significant reliability effects can be expected, making it extremely useful industrially.
