Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for mounting a small light bulb to a mounting board used in amusement equipment such as pachinko machines and slot machines.

[Prior Art] For example, in a pachinko machine, a large number of small light bulbs are attached to the back side of a mounting board made of a printed circuit board attached to the back side of a front nail board. The mounting structure for this small light bulb on a mounting board is, for example, by attaching a light bulb socket to the mounting board, connecting the wiring to the metal terminal of this light bulb socket by caulking or soldering, and then attaching a light bulb with a base (Edison base) to the light bulb socket. It was equipped with a small light bulb such as a Bayonet base or a wedge bulb.

[Problems to be solved by the invention] However, with the above conventional technology, connection work such as wiring, terminal crimping, and soldering is troublesome, and moreover, the work must be done in a narrow space when replacing or attaching/disconnecting light bulbs. Therefore, the work was extremely difficult.

In addition, vibrations are generated during operation of amusement equipment such as pachinko machines, and this vibration is transmitted directly from the mounting board and light bulb socket to the small light bulb and is added to its filament, which shortens the life of the small light bulb. was.

Regarding the lifespan of small light bulbs, it is known that it is most preferable for the filament to be positioned horizontally while the light bulb is lit. In such cases, it is difficult to fix the light bulb in the preferred position as described above, which also shortens the life of the light bulb.

The present invention solves these conventional problems; it is easy to assemble, can be easily attached to and removed from the mounting board even in confined spaces, and can extend the lifespan of small light bulbs. The purpose of the present invention is to provide a structure for mounting a small light bulb on a mounting board.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the mounting structure of the present invention for attaching a small light bulb to a mounting board has a main body made of an elastic insulating material, and a light bulb attached to the main body. A mounting hole and a lead wire extraction hole are drilled consecutively through the hole,
A pedestal part is formed at the bottom of the main body to sit on the mounting board below, and a fitting part with an irregular cross-sectional shape is formed below the pedestal part, which fits into the mounting hole of the mounting board below. A locking portion is formed below the fitting portion to lock under the mounting board, and a pair of lead wire guide grooves extending from the lead wire extraction hole to the constricted portion of the fitting portion are formed. and,
A light bulb part is attached to the light bulb mounting hole, a pair of outer lead wires drawn out from the light bulb part are passed through the lead wire draw-out hole, and further passed through the pair of lead wire guide grooves to form the constriction of the fitting part. A mounting hole corresponding to the fitting cross-sectional shape of the fitting portion of the socket is drilled at the upper surface of the locking portion, and a mounting hole corresponding to the fitting cross-sectional shape of the fitting portion of the socket is drilled. It is characterized by comprising a mounting board on which a pair of printed wiring for power feeding is provided on the back surface side to make contact with the connecting portions of the pair of outer lead wires, and to fix a socket in which the small light bulb is mounted.

[Function] When the locking part of the socket in which the small light bulb is attached is passed through the mounting hole of the mounting board, and the fitting part is fitted into the mounting hole of the mounting board, the locking part will fit under the edge of the mounting hole of the mounting board. By locking, the socket is positioned and fixed, and at the same time, the connecting portion of the outer lead wire is connected to the printed wiring for power supply arranged on the back side of the edge of the mounting hole.

In addition, since the socket made of insulating material has elasticity, it acts as a buffer between the mounting board attached to the back of a pachinko machine, etc. and the small light bulb, and the vibrations applied from the pachinko machine to the small light bulb through the mounting board are absorbed. will be moderated appropriately.

Furthermore, since the small light bulb uses a wire bulb type with an outer lead wire and does not have the conventionally commonly used screw-in cap, the filament must be positioned at a preferred predetermined position with respect to the socket. Since the socket and the mounting board are also positioned and fixed in a positioning relationship in which the mating cross-sectional shape is irregular, the small light bulb is eventually positioned at a preferred predetermined position with respect to the filament with respect to the mounting board. Can be installed in any condition.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

The mounting structure of a small light bulb on a mounting board shown in FIGS. 1 to 7 shows an embodiment in which a small light bulb is mounted vertically on a mounting board.

In these figures, reference numeral 1 denotes a socket, the main body of which is made of an elastic insulating material such as elastic resin or rubber material, and also has appropriate heat resistance. The main body 2 has, for example, a circular outer periphery, and a light bulb mounting hole 3 and a lead wire draw-out hole 4 are continuously formed through the main body 2 from the top to the bottom in the vertical direction.

The fitting part 6 has one side 6a formed in a substantially semicircular cross section, and the other side 6b formed in a rectangular cross section wider than the semicircle of the one side 4a, i.e. The fitting cross-sectional shape formed by combining the one side portion 6a and the other side portion 6b can be positioned when fitted into the mounting hole 51 of the mounting board 50. It is made into an irregular shape other than circular. Also, one side 6a of this fitting part 6
is formed in a constricted shape (constricted portion 7) between the upper and lower pedestal portions 5 and the locking portions 8.
A locking part 8 is provided at the lower part of the fitting part 6.

Note that the constricted portion 7 of the one side portion 6a of the fitting portion 6 is slightly opened toward the outer periphery so that it can be easily fitted into the mounting hole 51 of the mounting board 50.

The ends of printed wiring lines 52 and 53 for power feeding arranged on the back surface of the mounting board 50 are arranged at the edges.

Incidentally, since the socket 1 has elasticity, if the size of the fitting section of the fitting portion 6 is made slightly larger than the mounting hole 51 of the mounting board 50, the mounting of the socket 1 will be stabilized.

First, the fitting part 6 of the socket 1 is inserted into the mounting hole 51 of the mounting board 50 from the side 51a of the mounting hole 51 at a slight angle from the side 6a of the fitting part 6 of the socket 1. . Then, when the other side part 6b of the fitting part 6 is fitted into the other side part 51b of the mounting hole 51, the fitting part 6 of the socket 1 is fitted into the mounting hole 51 of the mounting board 50, and the pedestal The part 5 is seated on the edge of the mounting hole 51 of the mounting board 50 and the locking part 8
The socket 1 is fixed to the mounting board 50 because it locks the lower edge of the mounting hole 51 of the mounting board 50. Also, the outer lead wires 42, 42 of the small light bulb 40 attached to the socket 1 are connected to the socket 1.
The connection parts 43, 43 formed by wiring on the upper surface of the locking part 8 are connected to the printed wiring 5 for power supply of the mounting board 50.
Contact with 2,52. If the dimensions of the constricted portion 7 are set to be appropriate for the thickness of the mounting board 50, the socket 1 has elasticity, so that the locking portion 8 can be attached to the outer lead wire 4 disposed on its surface.
