Further, since the cover is made of rubber having elasticity and is opened and closed by bending, the cover has a problem of being cut off from a root portion which is a fulcrum of the opening and closing operation. Furthermore, since the elasticity of the rubber cover is used as the fulcrum for opening and closing, if an external force is applied to the cover by touching the closed cover, the holes and cover protrusions that hold the cover closed There is a problem that the cover is opened by overcoming the frictional force between the parts.

The present invention has been made to solve such a problem, and prevents the cover from protruding from the outer surface of the case during the opening / closing operation of the cover, and eliminates the portion that is bent during the opening / closing operation. It is an object of the present invention to provide a cover structure having excellent operability and durability and a high drip-proof effect.

 Hereinafter, embodiments will be described with reference to the drawings. 1 to 4 show a cover structure in an embodiment of the present invention, FIG. 1 (a) is a horizontal sectional view with the cover closed, and FIG. 1 (b) is a side sectional view with the cover closed. 2 is a plan sectional view showing a state where the cover is opened and the plug is connected to the internal connector, FIG. 3 is an external perspective view, and FIG. 4 is an enlarged view of part A of FIG.

In the figure, 11 is a case for covering an electronic device, 12 is an internal connector provided in the case 11, 13 is a printed wiring board for attaching the internal connector 12, and 14 is an internal connector 12 from the outside of the case 1. And 15 is a plug cable. Reference numeral 16 is a hole formed in the case 11 for inserting the plug 14 into the case 11.

Reference numeral 17 denotes a rectangular plate-shaped cover having a proper elasticity that slides to the left and right with respect to the case 11 to open and close the hole 16, and 18 denotes a sliding direction of the cover 17 among the four sides of the cover 17. The protrusions are formed on the two sides along the slide direction. Reference numeral 19 indicates a state in which the cover 17 closes the hole 16 and the central portion of the cover 17 facing the hole 16 is slightly recessed in a dome shape toward the hole 16 with a diameter slightly larger than the diameter of the hole 16. It is a convex inside.

Numeral 20 designates the outer surface of the case 11 as a square with the long side in the left-right direction so that the cover 17 does not protrude from the outer surface of the case 11 and can slide and move within the range in which the hole 16 can be opened and closed. The slide space 21 formed by recessing is formed on two opposite sides of the slide space 20 along the slide direction of the cover 17, and the projections 18 of the cover 17 are inserted to hold the cover 17 and slide the cover 17. It is a groove-shaped recess that serves as a guide for movement.

The hole 22 is formed by protruding the hole 16 in a tubular shape toward the outside of the case 11 so as not to prevent the cover 17 from opening and closing and to be in close contact with the inner protrusion 19 of the cover 17 in the closed state. The drip projections 23 are drainage grooves formed at both ends of the lower side of the slide space 20 in which the recess 21 is formed and are deeper than the recess 21 in the direction intersecting with the recess 21.

In the cover structure of the present embodiment having the above-described configuration, the projection 18 of the cover 17 is inserted into the recess 21 provided in the slide space 20 of the case 11 to hold the cover 17 in the case 11 and The structure is such that it can be slid on the recess 21 to open and close. In order to prevent water droplets from entering the case 11 through the hole 16 when the cover 17 is closed, a drip-proof projection 22 is formed on the case 11 side, and an inner protrusion 19 is formed on the cover 17 side. When the cover 17 is closed, the inner protrusion 19 is pressed by the elasticity of the cover 17 so as to fit into the drip-proof projection 22. Therefore, a gap between the cover 17 and the drip-proof projection 22 is formed. 20a is zero and is in close contact.

A gap 20b is opened between the slide space 20 and the cover 17 other than the inner protrusion 19 and the drip-proof protrusion 22, and water drops entering the gap 20b and the recess 21 are drained 23. Is discharged to the outside of the case 11. When connecting the plug 14 to the internal connector 12, the cover 17 is slid in the slide space 20 using the recess 21 as a guide to open the hole 16 so that the plug 14 can be connected to the internal connector 12 through the hole 16. Becomes

At this time, since the cover 17 has elasticity, the inner protrusion 19 that is in close contact with the drip-proof projection 22 does not interfere with the opening operation of the cover 17, and thus the drip-proof projection 22 does not interfere. Can get over. The cover 17 in which the hole 16 is open does not protrude from the outer surface of the case 11 and does not become a nuisance to the operation because the protrusion 18 enters the recess 21 and is housed in the slide space 20.
