Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a case body used for antenna-related equipment such as boosters and mixers, and a structure of a slide lid that fits into the case body.

Construction products such as the booster described above require work such as attaching the booster to other objects as well as connecting and adjusting cables to the booster itself. In this case, the sliding lid must be closed during shipping to protect the inside, and the lid must be opened during construction. In such a case, conventionally there was only one locking position when the slide lid was opened, resulting in the following drawbacks. In other words, when you casually open the slide lid,
The force of the opening could cause the lid to come off the case beyond the locking position, causing it to fall out of your hand, resulting in damage or loss. Furthermore, when one case lid is shared by various other devices, the proper locking position of the slide lid differs from device to device, making it difficult to perform construction work. If you set the lock position so that the slide cover is close to fully open so that it can be used for all devices temporarily, parts on the wiring board inside the case body may come into contact with tools such as screwdrivers, or hands may deteriorate performance. There was a high possibility that this would happen.

The present invention eliminates the above-mentioned drawbacks and allows the slide lid to be easily locked in any position convenient for the construction worker. In addition, there are two or more lock positions,
Moreover, by setting the locking strength to gradually increase as the slide cover is opened, even if the cover is opened casually, the force of opening the cover prevents the cover from coming off from the case body.

An embodiment of the present invention will be described below in detail with reference to the drawings. Fig. 1 is a perspective view of the case body with the slide lid completely closed. 2 is a cross-sectional view taken along line bb' in FIG. 1, FIG. 3 is a cross-sectional view taken along line b-v in FIG. 1, with the case body and lid separated, and FIG. Figure 6 is a sectional view taken along line a-a' in Figure 1 showing the case body and lid fitted together (lid closed), and Figure 6 is a sectional view with the lid partially open for construction purposes. be.

In the figure, reference numeral 1 denotes the case body, which has a box-like shape with only the top open, and is attached to the upper edge of a pair of opposing side walls in a direction perpendicular to the side walls so that it fits with the slide lid 1 and allows the slide lid 2 to slide. A protruding piece 3°3 is provided integrally. Moreover, a plurality of bosses 4 are integrally provided inside the case body 1 so that the wiring board P can be fixed thereto.

On the other hand, the sliding lid 2 has grooves 6, 6 formed by processing a pair of opposite edges into a U-shape so that the sliding lid 2 can fit into the projections 3, 3, and the sliding lid 2 can be moved to any position. A plurality of protrusions 6° 7, 8 are continuously provided at a predetermined interval on the back surface of the main plane portion in the sliding direction so as to be locked in the open state. Here, protrusion 6. 7.8, the height hs of the protrusion 8 located at the tip in the sliding direction when closing is the highest, and the height h2 of the protrusion 7 located behind it is set to the height hs of the protrusion 8
The height hl of the protrusion 6 located at the rearmost end, that is, the tip in the sliding direction when opening the slide lid 2, is set to be the lowest. In the illustrated example, the protrusion 6. 7
．． Two rows of 8 are provided. The number of columns may be one, or three or more.

Further, for the case body 1, a protruding piece 9 serving as a stopper is integrally provided on the upper edge of one of the side walls located between the side walls provided with the protruding pieces 3.
Correspondingly, the slide lid 2 is integrally provided with a U-shaped portion constituting a groove 1o into which the protruding piece 9 fits. In addition,
The protruding piece 9 on the case body 1 side may not be provided, and the slide lid 2 may be provided with a protruding piece that protrudes perpendicularly (downward) to its main plane.

FIG. 4 shows the state in which the slide lid 2 is completely closed. When the slide lid 2 is opened from this state by sliding it in the direction of the arrow, the protrusion 6 first forms the protrusion piece 9. However, as the sliding lid 2 is deflected outward (in the direction of arrow C) due to the opening force, the protrusion 6 overcomes the protrusion 9 and further moves in the direction of the arrow.

Figure 5 shows that the protrusion 6 has completely climbed over the protrusion 9 and is located outside of it, and the next protrusion 7 comes into contact with the upper end of the side wall that has the protrusion 9, and the slide lid 2 is locked. Indicates the condition. That is, the slide lid 2 is opened halfway, and in this state, work inside the case body 1 can be performed using the screwdriver 11. At this time, the distance between the protrusions 36 and 7 and between the protrusions 7 and 8 may be equal to the width of the protrusion piece 9, or may be wider than the width of the protrusion piece 9. And protrusion 6. 7. The height of 8 is h+<
Since h2<hs is set, the locking strength increases sequentially as the slide lid 2 is opened. Therefore, there is no possibility that the slide cover 2 will come off the case body 1 even if the cover 2 is casually opened, and there is no risk of the slide cover 2 being lost or damaged. Moreover,
Since the open state of the slide lid 2 can be made larger or smaller depending on the degree of work, there is no fear that parts will be accidentally touched by a screwdriver, hand, etc. and the performance will be degraded during work.

On the other hand, when closing the slide lid 2, it is sufficient to slide the slide lid 2 in the direction of arrow B in the opposite direction to when opening it. In addition, in the above embodiment, the slide lid 2 is not easily opened from the completely closed state.
A protrusion 12 is integrally provided on the back surface of the edge of the slide lid 2 opposite to the edge provided with the groove 1o, so that the closed state is locked. In addition, in this embodiment, the protrusions 6 having different heights
．． Although three 7.8s were provided, more may be used.

As explained above, according to the present invention, by providing a plurality of locking protrusions on the back surface of the slide cover, when opening the slide cover, the slide cover can be locked at a plurality of positions. The opening/closing state can be adjusted, and as a result, there is no risk of tools or hands touching parts that should not be touched during work.This also eliminates the risk of touching parts, improving work efficiency. By sequentially changing the height of the multiple protrusions so that the locking strength increases as the slide cover is opened, the slide cover will not come off from the case body even if the slide cover is opened casually. Therefore, there is no risk of losing or damaging the slide lid.
