続する必要がある。The above-mentioned conventional technology has problems that are difficult to solve, such as water leakage from joints and the occurrence of rust. As a means to solve this problem, a technique for bonding metal plates together using a structural bonding agent has been developed and is publicly known. On the other hand, structures and reinforcing members used for the exterior of electronic equipment, such as doors and waist panels, are used to prevent danger to the human body, eliminate ground-induced noise, and determine the potential of metal inside the equipment. It is necessary to make an electrical connection to ensure that

補強部材の接地構造を提供することにある。An object of the present invention is to provide a grounding structure of a reinforcing member attached with a structural bonding agent as reinforcement to a structure made of processed thin metal plates used in electronic equipment.

とにより、達成される。The above purpose is to attach one end of a flexible metal temporary spring to a part of a reinforcing member joined to a structure made of thin metal plates using a connecting means such as a screw or rivet. This is achieved by keeping one end in constant contact with the surface of the structure.

電位は構造体と同じになる。The metal leaf spring attached to the reinforcing member is always pressed against the structure with appropriate pressure. As a result, the structure and the reinforcing member, which had been electrically insulated by the adhesive layer, are connected, and the electrical potential of the reinforcing member, which was an electrically floating metal, becomes the same as that of the structure.
以下、本発明の一実施例を第１図により説明する。構造
体１は例えば扉、腰パネルなど電子機器の外装として用
いられる金属製の構造体である。An embodiment of the present invention will be described below with reference to FIG. The structure 1 is a metal structure used as an exterior of an electronic device, such as a door or a waist panel.

方法が有効である。次に詳細を第２図により説明する。The structure 1 is formed into a box shape by bending a thin steel plate, so that if the outer shape is small, the strength of the material and the rigidity of the structure itself can withstand warping and distortion that occur when opening and closing the electronic device. However, as the structure becomes larger, it becomes unable to withstand the warping and distortion that occur during attachment/detachment, opening/closing, and may eventually suffer permanent deformation. In such cases, it is common to attach a reinforcing member 2 having a cross section with a high section modulus to the surface of the structure. The reinforcing member 2 can be attached using bolts, rivets, welding, etc., but it is difficult to avoid holes, deformation due to heat, and rust, especially in structures where you want to take advantage of the characteristics of the material, such as PVC steel plates, colored steel plates, and plated steel plates. is not suitable, and a method of bonding with structural bonding material 3 is effective. Next, details will be explained with reference to FIG.

のばね効果をもっている。A square hole 4 is drilled in the flat part of the reinforcing member 2, and the square hole 4 has a sufficient size for attaching the leaf spring 5, and a screw hole for attaching the leaf spring 5 is provided around the square hole 4. It is. One end of the plate spring 5 has a hole for attaching the plate spring itself to the reinforcing member 2, and is fixed to the reinforcing member 2 with a screw 6. The other end of the leaf spring 5 has a gentle slope and is slightly curled at the part where it contacts the surface of the structure 1, and has an appropriate spring effect that always presses the surface of the structure 1 with a constant pressure.

る。According to the present invention, the plate spring fixed to the reinforcing member and brought into contact with the structure connects the structure and the reinforcing member, which were electrically insulated by the adhesive layer, and reinforcing the electrically floating metal. Since the potential of the member is the same as that of the structure, the potential of the metal inside the device is determined, which has the effect of preventing danger to the human body, eliminating ground induced noise, and blocking external radio waves.
