Abstract

PROBLEM TO BE SOLVED: To prevent displacement of a case toward its back if the case is exerted with a force to pull it toward the back, so that the force does not work on projecting and recessed fitting parts where the case and a lid part are fitted together. SOLUTION: This mounting device has a case 1 open on its front and a lid part 2 mounted in the front opening in the case 1, and is used suitably for mounting electrical equipment such as a time switch in a hole 4 in a panel 3 in which it is mounted. A projecting piece 5 formed at the edge of the front opening in the case 1 and the outer surface of the lid 2 are locked together by a fit between the projecting and recessed parts. The fit between the projecting and recessed parts is achieved by fitting the projection 6 formed on the outer surface of the lid part 2 into a hole (or recess) 7 formed in the middle of the projecting piece 5. A positioning projecting part 8 formed outward from the front end of the projecting piece 5 has its back substantially positioned and a abutted to the front surface of the edge of the hole 4 in the panel 3.

2. Description of the Related Art Some electric devices such as a time switch are provided with a case whose front surface is open and a lid portion which is attached to the front opening of this case. In order to attach this electric device to the hole of the panel, it is often the case that this is pushed in from the front surface of the hole and a locking piece formed at an appropriate position of the front opening edge of the case is locked to the hole edge. In this attached state, the rear surface of the flange portion formed so as to project outward on the front surface side of the lid portion contacts the front surface of the hole edge. For mutual attachment of the case and the lid, it is known that the projection formed on the front opening edge of the case and the outer surface of the lid are engaged by concave and convex fitting.

However, in the above-mentioned prior art, since the lid portion is prevented from being displaced in the rear direction by the abutment of the flange portion and the panel, the case with the electric device attached to the panel is prevented. It should be noted that there is a problem to be solved in that the force is applied to the concave-convex fitting portion that is the attachment portion between the case and the lid portion if the member is carelessly pulled from the back surface. Particularly, in the case where the front end of the bent piece formed on the back surface of the case and formed on the side portion presses the back surface of the panel to provide the final installation state, a particular problem occurs. Cheap. This is because the reaction force of the pressing force applied to the back surface of the panel by the bent piece of the attachment always acts as a force for displacing the case toward the back surface. In view of such problems to be solved, the present invention, as a device for mounting an electric device in a hole of a panel, prevents displacement of the case in the back direction when a force pulling in the back direction is applied to the case. The purpose is to prevent the force from acting on the concave-convex fitting portion that is the attachment portion between the case and the lid portion.
