[Industrial applications]

 The present invention relates to an improvement of a structure for fixing an electronic component for electrically controlling a lighting device in the lighting device.

[0002]

[Prior art]

 Conventionally, in lighting fixtures, in particular in stand lighting fixtures, the structure for fixing electronically controlled electronic components to the lighting fixture has been a blocked electronic structure in which the electronic components are previously attached to the terminal frame with respect to the mounting frame. After fixing the component block to the resin insulating plate that also serves as a lid with a special screw, attach this electronic component to the terminal board to attach the resin insulating plate that also serves as a lid to the blocked electronic component block. After re-fixing with screws or electronic component blocks that are made into blocks by attaching electronic components to the terminal board beforehand, after fixing with resin insulating plates to the metal lid with locking support By fixing the electronic parts by this locking support with screws, the electronic parts block made into blocks is fixed while sandwiching the insulating plate. That the composed lid formed of a fixed to the mounting frame by a screw is generally used.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional one, the electronic component block, which is made into a block by previously mounting the electronic component on the terminal plate to the mounting frame, is fixed to the resin insulating plate also serving as the lid with the dedicated screw, and the electronic component is also mounted. The electronic component block, which is made into a block by attaching to the terminal board, is fixed to the metal lid with the locking support while sandwiching the resin insulating plate, and then fixed with the screw. A block of electronic parts that is blocked by attaching electronic parts to the terminal board is fixed directly to the resin insulating plate that also serves as the lid, or indirectly by sandwiching the insulating plate and fixing it to the metal lid with screws. Since it is necessary to fix it to the mounting frame again with screws, the workability is reduced because the mounting and fixing work is complicated, and moreover, the number of parts is large and the cost is high. There is a disadvantage that the burden of the increases, moreover, when the mounting frame is provided at the narrow on the outer shape of the luminaire is further fixing work for hardly contains the screwing tool it becomes difficult.

Further, in particular, an electronic component block, which is made into a block by attaching an electronic component to a terminal plate, is indirectly fixed by a screw to a metal lid while sandwiching an insulating plate, and then screwed again to the attachment frame. When fixing the electronic component block to the terminal plate by attaching the electronic component to the metal lid, fix the electronic component block with an insulating plate between the lid and the electronic component block in order to prevent leakage. However, if a certain level of mounting accuracy is not secured when fixing this electronic component block, there will be a leak between the backside of the terminal board where the electronic components are mounted and the metal lid. It may occur, and the control of lighting equipment may be lost.

Therefore, the present invention is to improve the drawbacks of the above-mentioned conventional ones, and by mounting the electronic component on the terminal board while ensuring sufficient insulation with respect to the mounting frame with a simple structure. This makes it possible to easily and surely fix the blocked electronic component block.

[0006]

[Means for Solving the Problems]

 For this purpose, a locking claw portion that protrudes inward is formed on the upper end edge of the mounting frame having a substantially U-shaped cross-section whose bottom surface is curved toward the flat surface or outward, and heat is applied. An electronic component holder that is made of a plastic insulating material and has outwardly protruding elastic blade pieces that project outward and that holds an electronic component block body with a locking piece is provided inside the opening. On the edge part, at the positions corresponding to the locking claw parts arranged on both edges of the mounting frame, the locking projections that elastically expand outward are formed, and Then, by dropping the electronic component holder, the locking projections are elastically locked to the locking claws of the mounting frame, and each is integrally fixed.

Further, in an electronic component holder formed of a thermoplastic insulating material fixed to a mounting frame, an electronic block body is formed by forming a guide projection integrally formed at a predetermined inner position. When it is held in the electronic component holder, the electronic component block body is held at the correct mounting position by inserting it into the guide hole provided at the predetermined position of the terminal plate that constitutes the electronic component block body. It is something that can be done.

[0008]

[Action]

 Because of the above configuration, when fixing the electronic component holder that holds the electronic component block body to the mounting frame, first attach the electronic component to the terminal board and block the electronic component block body with thermoplastic insulation. By being inserted into the electronic component holder made of a material, the electronic component block body is locked and held by the locking piece integrally formed in the electronic component holding body, and the electronic part block body is inwardly held by the locking piece. The electronic component holder that holds and holds the electronic component holder with guides protruding vertically to the left and right at the opening edge of the electronic component holder, with the bottom surface facing flat or outward. The mounting frame that has a U-shaped cross section that is curved is inserted into the mounting frame along with the locking claws that project inwardly at both edges, preventing lateral movement and preventing electronic components. Take the above-mentioned holder The elasticity of the locking projections formed at the positions corresponding to the locking claws arranged on both edges of the frame causes the elasticity to expand outwards, so that the locking projections move inward toward both edges of the mounting frame. It is easily locked by the locking claw that protrudes.

At this time, the elastic blade pieces that are formed on the outer surface of the electronic component holder that holds the electronic component block body inwardly and project outwardly are brought into contact with the bottom surface portion of the mounting frame, The elasticity of the electronic component holder acts in the repulsive direction when it is dropped into the mounting frame, and the electronic component holder itself is urged upward, resulting in both ends of the mounting frame. It has elasticity toward the outside that is formed at the positions corresponding to the locking claws that project inward at the edges and the locking protrusions that are arranged at both edges of the mounting frame of the electronic component holder. It will push against the locking part with the expanding locking projection, and the locking at this locking part will be stronger, so make sure that the electronic block is secured inward in the mounting frame. The electronic component holder that holds the body can be fixed and can be attached to the mounting frame. Even when vibrations occur due to vibration, since the elastic blades protruding from the outer surface of the electronic component holder elastically contact the bottom surface of the mounting frame, the vibrations are absorbed and absorbed. It is also possible to prevent the electronic component holder held inside from resonating.

When inserting the electronic block body into the electronic component holder, a guide protrusion is formed at a predetermined position inside the electronic component holder to form the electronic component block body, and The electronic component block body is guided to a predetermined position of the electronic component holder by inserting the guide hole provided in the terminal board on which the electronic component is attached, and the electronic component block body is quickly and accurately held in the electronic component holder. be able to.

(1) is a mounting portion of a stand lighting fixture including an embodiment of the present invention. The mounting portion (1) of the stand lighting fixture includes a metallic mounting frame (2) and this mounting frame (2). An electronic component holder (3) that is fixed integrally inside and holds an electronic component block body (4) that is formed into a block by mounting an electronic component inside the terminal plate (5). It will be done.

Then, the bottom surface portion (6) is curved inward toward the plane or outward, and is directed inward toward the upper end edges (7) and (7) of the mounting frame (2) having a substantially U-shaped cross section. And a locking claw portion (8) that protrudes outward, and an elastic blade piece (9) that is molded from a thermoplastic insulating material and that protrudes outward is formed on the outer surface, and the locking piece (9) is formed inward. At the opening edge portion (11) of the electronic component holder (3) holding the electronic component block body (4) with the above (10), the upper edge (7) (of the mounting frame (2) ( 7) A guide (12) protruding vertically to the left and right is provided at a position corresponding to the locking claw portion (8) arranged in 7), and the locking elastically expands outward. A protrusion (13) is formed, and the electronic component holder (3) is dropped into the mounting frame (2) so that the locking claw portion (8) of the mounting frame (2) is located. Then, the locking projection (13) of the electronic component holder (3) is elastically locked, and the mounting frame (2) and the electronic component holder (3) are integrally fixed.

Further, in the electronic component holder (3) formed of a thermoplastic insulating material fixed to the mounting frame (2), a guide protrusion (14) integrally formed at a predetermined inner position is formed. Thus, when the electronic block body (4) is held in the electronic component holder (3), the guide hole (15) is provided at a predetermined position of the terminal plate (5) constituting the electronic component block body. ), The electronic component block body (4) is accurately positioned and held at a predetermined position of the electronic component holder (3).

Since the present invention has the above configuration, the electronic component block body (4) for electrically controlling the lighting fixture is held with respect to the mounting frame (2) of the lighting fixture mounting frame position (1). In fixing the electronic component holder (3), first, the electronic component block body (4), which is made into a block by attaching the electronic component to the terminal board (5), is replaced with an electronic component holder (made of thermoplastic insulating material). By being inserted into 3), the electronic component holding body (3) is elastically locked and held by the locking piece (10) formed integrally with the electronic component holding body (3) while ensuring insulation. Further, the electronic component holder (3), which is elastically locked and held by the locking piece (10) inward, holds the electronic component block body (4) at the open end of the electronic component holder (3). At the edge (11), in the vertical direction to the left and right The protruding guide (12) is inwardly attached to the upper end edge (7) of the mounting frame (2) having a substantially U-shaped cross section formed by curving the bottom surface (6) toward the plane or outward. By aligning with the locking claws (8) projecting toward the inside and dropping it into the mounting frame (2), the electronic component holder (3) is attached to the end edge (7) of the mounting frame (2). The locking projections (13) formed at the positions corresponding to the locking claws (8) arranged are bent when the electronic component holder (3) is dropped into the mounting frame (2). Due to its elasticity, it spreads outward, and is easily locked by the locking claws (8) protruding inward at both edges (7) of the mounting frame (2). The electronic component holder (3) can be fixed in the mounting frame (2).

[0016] Furthermore, particularly when it is used as a stand device and is used in an upright state, there is a possibility that the device may be dropped, an external force or a shock may cause connection of the power block, and lighting failure may occur. Thus, the locking claw portion (8) of the mounting frame (2) is prevented from moving so that the above connection and lighting failure do not occur. The elastic blade pieces (9) formed on the outer surface of the electronic component holder (3) for holding the electronic component block body (4) inward and projecting outward are attached to the mounting frame (2). By contacting the bottom part (6) of the electronic component holder (6), the elastic blade pieces (9) of the electronic component holder are moved in a repulsive direction against the electronic component holder (3) being dropped into the mounting frame (2).

In addition, even if vibration is applied to the mounting frame (2) because vibration is applied to the mounting portion (1) of the lighting fixture, the electronic component protection is performed on the bottom surface portion (6) of the mounting frame (2). Since the elastic blade pieces (9) protruding to the outer side surface of the holding body (3) are always in elastic contact with each other, the vibration to the mounting frame (2) is buffered and absorbed. It is also possible to prevent resonance of the electronic component holder (3) that is held inside the bracket.

In inserting the electronic block body (4) into the electronic component holder (3), a guide protrusion (14) is formed at a predetermined position inside the electronic component holder (3). Thus, the electronic component block body (4) is configured, and the electronic component block body (4) is inserted by inserting the guide hole (15) arranged in the terminal plate (5) to which the electronic component is attached in advance. Is guided to a predetermined position of the electronic component holder (3), and the electronic component block body (4) can be held in the electronic component holder (3) quickly and accurately.

The shape of the elastic blade piece (9) formed on the outer side surface of the electronic component holder (3) for holding the electronic component block body (4) inward and projecting outward is shown in FIG. As shown in FIG. 4, in the case of this embodiment, since the bottom surface portion (6) of the mounting frame (2) is curved outward, the electronic component holder (3) is attached to the mounting frame (2). When it is dropped inside, the elastic blade piece (9) has to be in contact with the bottom surface portion (6) in the mounting frame (2) so that it has elasticity, so it has a linear shape. When the bottom surface part (6) in the frame (2) is flat, the elastic blade pieces (9) formed on the outer surface of the electronic component holder (3) and protruding outward are attached. By having a curved surface or a V-shape, the bottom surface (6) in the mounting frame (2) can be elastically contacted. You may choose to do this.
