Abstract

(57) [Abstract] [Purpose] The present invention is a lid lock mechanism for an electronic device housing, which does not require the lid to be pressed down during maintenance, inspection, etc., so that the lid remains open. It is intended to be held in a state. [Structure] A small protrusion 26 is provided on the surface of a shaft 23 arranged in parallel along an upper edge 21a of a casing body 21, and a small projection 26 is provided along the shaft 23 at an upper end portion 22a of a lid 22 which opens and closes with the shaft 23 as a fulcrum. The arcuate portion is provided with a bent portion 25 whose tip is in sliding contact with the surface of the shaft 23. When the lid 22 is opened, the tip of the upper bent portion 25 of the lid 22 has the tip of the shaft 23.
The small projection 26 is crossed over and retained.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lid lock mechanism for an electronic device housing used for a power amplifier for communication, a signal distributor, a branching device, and the like.

[0002]

[Prior art]

 3A and 3B show a configuration of a conventional electronic device housing. FIG. 3A is a side view thereof, and FIG. 3B is a rear view thereof.

For example, the signal distributor and the branching device are used by being vertically mounted on a wall surface or a pillar of a building, and a front side surface is a lid 12 with respect to a housing body 11, and the lid 12 is a housing. A shaft 13 arranged parallel to the upper edge of the main body 11 is used as a fulcrum to open upward toward the front.

[0004]

[Problems to be solved by the device]

 However, since the above-described conventional electronic device housing does not have a mechanism for holding the lid 12 in the opened state when the lid 12 is opened from the housing body 11, it is possible to perform maintenance, inspection, etc. However, there is a very troublesome defect that the work must be carried out while holding the lid 12 by hand so as not to lower it.

The present invention has been made in view of the above problems, and it is possible to hold the lid in an open state without having to hold it by hand during maintenance, inspection, etc. so as not to lower it. An object of the present invention is to provide a lid lock mechanism for an electronic device housing.

[0006]

[Means for Solving the Problems]

 That is, a lid lock mechanism for an electronic device casing according to the present invention comprises a shaft arranged in parallel along one edge of the casing body, and a lid for opening and closing the casing body with this shaft as a fulcrum. A sliding contact portion which is provided on the inner surface of the corresponding lid facing the surface of the shaft and whose tip moves in sliding contact with the surface of the shaft when the lid is opened and closed, and a fully opened state of the lid. And a small projection provided immediately before the end point of the sliding contact of the surface of the shaft by the sliding contact portion.

[0007]

[Action]

 In other words, when the lid is fully opened, the sliding contact portion thereof rides over the small protrusion of the shaft and is engaged and held by the small protrusion.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1A and 1B show the structure of a lid lock mechanism of an electronic device housing. FIG. 1A is a central longitudinal sectional view thereof, and FIG. 1B is a rear side front view thereof.

The electronic device casing is composed of a casing body 21 facing one side and a lid 22 facing the other side, and is arranged on the upper side of the casing body 21 in parallel with the upper end edge 21 a thereof. A cylindrical shaft 23 is provided, and the lid 22 is opened from the lower side to the upper side with the shaft 23 as a fulcrum.

Here, the upper end portion 22a of the lid 22 is formed in an arc shape along the outer peripheral surface of the shaft 23, and the arc shape portion of the upper end portion 22a of the lid 22 has both end portions 24a, It is formed so as to wrap around to the back side only at 24b, and between both ends 24a and 24b, it wraps around the arc-shaped top of the arc-shaped portion at the upper end 22a of the lid 22 with the lid 22 closed. To be done.

That is, in the back side front view “see FIG. 1B” in the state where the lid 22 is closed, in the inside surrounded by the upper end portion 22 a of the lid 22 and both end portions 24 a and 24 b thereof, The upper half of the shaft 23 appears along the upper edge 21a of the housing body 21. Then, when the lid 22 is opened, the arc-shaped top portion of the lid 22 comes into contact with the upper end edge 21a of the housing body 21 to be in a fully opened state.

Further, the tip end portion of the arcuate top portion along the shaft 23 in the upper end portion 22 a of the lid 22 is bent toward the center direction of the shaft 23, and the upper end of the lid 22. The bending length of the bent portion 25 is such that the tip of the bent portion 25 is in light contact with the surface of the shaft 23. That is, the tip of the bent portion 25 is brought into light sliding contact with the surface of the shaft 23 as the lid 22 is opened and closed.

Further, a small protrusion 26 is provided at the center of the upper back surface of the shaft 23, and when the lid 22 is fully opened, the tip of the bent portion 25 at the upper end 22 a of the lid 22 is The small protrusion 26 is configured to be crossed over and engaged.

2A and 2B show a fully open locked state of the lid locking mechanism of the electronic device housing, FIG. 2A is a partial sectional side view thereof, and FIG. 2B is an enlarged partial sectional view thereof. is there.

That is, when the lid 22 is opened with respect to the housing body 21, the upper end bent portion 25 of the lid 22 moves clockwise while sliding the surface of the shaft 23 in the figure, and the The small projections 26 provided on the surface are crossed over and engaged.

At this time, the arc-shaped top portion of the lid 22 comes into contact with the upper end edge 21a of the housing body 21 to be in a fully opened state, and the lid 22 covers the small projection 26 provided on the shaft 23 on the housing body 22 side. Since the tip of the upper end bent portion 25 of 22 is engaged, the lid 22 can be fixed and held in the fully opened state.

When the lid 22 is closed, the locking piece 28 provided on the lower inside of the lid 22 is engaged with the engaging piece 27 provided on the lower portion of the housing main body 21. The lid 22 is fixedly held in the fully closed state.

Therefore, according to the lid lock mechanism of the electronic device casing having the above-described configuration, the small protrusion 26 is provided on the surface of the shaft 23 arranged in parallel along the upper end edge 21a of the casing body 21, and the shaft 23 is attached. The upper end 22a of the lid 22 that opens and closes as a fulcrum has an arcuate portion along the shaft 23 with a bent portion 25 whose tip slides on the surface of the shaft 23. When the lid 22 is opened, Since the tip of the upper end bent portion 25 of the lid 22 is configured to be engaged and held over the small protrusion 26 of the shaft 23, the lid 22 is pushed up by hand during maintenance and inspection of the inside of the electronic device housing. It is not necessary and can be fixedly held in the open state, greatly improving workability.

[0019]

[Effect of device]

 As described above, according to the present invention, a shaft that is arranged in parallel along one edge of the housing body, a lid that opens and closes the housing body with this shaft as a fulcrum, and a surface on the surface of the shaft. And a corresponding sliding contact portion provided on the inner side surface of the lid, the tip of which moves in sliding contact with the surface of the shaft when the lid is opened and closed, and the sliding contact portion in the fully opened state of the lid. A small protrusion is provided on the surface of the shaft immediately before the end point of the sliding contact, and when the lid is opened, the sliding contact portion crosses over the small protrusion of the shaft and is engaged and held by the small protrusion. During maintenance, inspection, etc., it is possible to hold the lid open without having to hold it by hand to prevent it from lowering.
