JP 05-291759 A

The conventional electrical component storage case has the following problems, for example.
(1) A cylindrical case, a packing that seals the outer periphery of the opening of the case and the periphery of the wire at both ends of the case, and a structure that includes a mounting bracket for holding the packing and attaching it to a lighting fixture. The work was complicated, such as passing through the packing and fixing the mounting brackets to the both ends of the electrical component storage case with screws, and it took time to assemble.
(2) Normally, the luminaire main body to which the electrical component storage case is attached is diverted from the general environmental luminaire main body to which the stored electrical component is attached or the drilling of the main body. Since the mounting holes are covered with the case, the electrical component storage case cannot be mounted in the mounting holes processed in the lighting fixture body in accordance with the mounting hole pitch of the electrical components. In order to attach the electrical component storage case to the main body of the luminaire, an attachment structure for making the mounting hole of the electrical component storage case and the mounting hole of the luminaire main body the same pitch is added, or the electrical component storage case In accordance with the pitch of the mounting holes, it was necessary to additionally process the mounting holes in the lighting fixture body.

The present invention provides, for example, an electrical component storage case that does not have a packing retainer and mounting bracket, reduces the number of components, significantly reduces assembly time, and has high waterproof performance. Objective. Another object is to provide an electrical component storage case that is compatible with the mounting pitch of a single electrical component to be stored.
For example, when an electrical component has a quick connection terminal, it aims at providing the electrical component storage case which can be connected to an electrical component after the assembly of an electrical component storage case, and can visually confirm the connection state.

The electrical component storage case of the present invention is
Among the electrical parts having a main body part and an attachment hole provided at the end of the main body part, a storage case main body for housing the main body part of the electric part, and an opening for protruding the attachment hole of the electric part A storage case body having,
A packing for covering the mounting hole of the electrical component protruding outward from the storage case body and closing the opening of the storage case body.

  ADVANTAGE OF THE INVENTION According to this invention, it can be set as the electrical component storage case with high waterproof performance reliability. Furthermore, an electrical component storage case compatible with the mounting pitch of the electrical components to be stored can be provided.

The position of the mounting hole 232 of the ground metal fitting 230 overlaps the position of the mounting hole 224 of the packing 220. The tip of the convex portion 231 is not molded and is in contact with the electrical component 300 to conduct.

  The screw 331 is inserted into the aligned mounting hole 311 of the electrical component 300, the mounting hole 224 of the packing 220, and the mounting hole 232 of the grounding metal 230, and is fixed by the nut 332.

The packing 220 includes a main body contact portion (a portion where the convex portion 221 is provided) in contact with the outer periphery of the end portion of the storage case main body 210 and a component contact portion (a portion where the mounting hole 224 is provided) which is in contact with the main body portion 310 of the electrical component 300. And at least one portion excluding the wire contact portion (the portion where the through hole 222 is provided) in contact with the electric wire 322, the pressure adjusting portion 240 for adjusting the pressure in the electric component storage case 200 is provided. Since the packing 220 enhances the airtightness inside the case, the temperature inside the case rises due to the heat generated by the electrical component 300, the air inside the case expands, the air pressure inside the case increases, and each contact portion of the packing 220 (main body This is to prevent the sealing function (adhesion) of the contact portion, the component contact portion, and the wire contact portion) from being weakened.
