Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push button device for selecting a product of a vending machine, and more particularly, to a fastening structure of a harness pulled out from the push button device. 2. Description of the Related Art FIG. 3 shows the structure of a vending machine to which the present invention is applied. In the drawing, reference numeral 1 denotes a cabinet main body of a vending machine in which a product storage rack and a cooling / heating unit are mounted in a refrigerator, 2 is a front outer door, 3 is a product outlet, 4 is a coin mechanism, a building validator, and the like. A sales operation unit, 5 is a display room in which a product sample 6 is displayed, 5a is a front panel (transparent plastic light board) of the display room 5, and 7 is a front surface of the display room 5 so as to correspond to the product sample 6 individually. Is a push button device for selecting a product, which is arranged in the product. Here, the push button device 7 is shown in FIG.
As shown in (b), the push button 7a, the push button 7a
After the switch element 7b responding to the pushing operation of the button and the printed board 7c on which the input / output control IC is mounted are attached to the long button case 7d having a sheath shape, the button case 7
d is arranged on the front side of the front panel 5a, and a channel-shaped mounting metal (sheet metal processed product of thin steel plate) 8 serving also as a harness duct is arranged on the back side of the button case 7d with the front panel 5a interposed therebetween. The case 7d is fixed with a fastening bolt (not shown) penetrating the front panel 5a. Further, on the back surface of the button case 7d, there are provided connector terminals 7e respectively corresponding to the printed boards 7c of the respective switch elements 7b, which penetrate through the front panel 5a and protrude to the rear. The harness 10 connected to the connector 9 via the connector 9 is routed collectively along the inside of the U-channel duct portion 8a formed on the mounting member 8, and pulled out from the end of the mounting member 9 (on the hinge side of the outer door 2). Wiring is to be made between the electrical box in the refrigerator. Further, in order to keep a large number of harnesses 10 laid in the duct portion 8a of the mounting metal 8 in a bundle so that they do not vary, a conventional U-shaped clamp fitting 1 is used.
1 is mounted on the mounting bracket 8 via the pivot pin 11a,
With the harness 10 laid, the clamp fitting 11 is tilted from the standing position to the position shown in the drawing, so that the harness 10 is
a. [0006] By the way, as described above, in the conventional structure in which the attachment metal 8 is provided with a separate clamp metal 11 as a fastener of the harness 10, the clamp metal 1
1. The number of additional parts including the pivot pin 11a and the number of assembly steps increase, and the manufacturing cost increases. SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object the purpose of using a large number of wires that are drawn and wired to the mounting hardware of a push button device with a simple structure and operation without using parts of a harness fastener such as a clamp. To provide a push button device for selecting a product of a vending machine improved so that the harness can be collectively held. In order to achieve the above object, according to the present invention, there is provided a push button device for selecting a product of a vending machine mounted on the front of a display room for displaying a sample product. A push button, a switch element, a sheath-shaped button case assembled with a printed board, and a mounting plate also serving as a harness duct are overlapped and fastened on the front and rear surfaces of the front panel of the display room, and pulled out from the button case. In the case where the harness corresponding to each of the buttons is routed along with the inside of the mounting metal duct, a bendable tongue-shaped harness fastening piece is provided on the trailing edge side of the mounting metal duct, and the mounting hardware is provided. With the harness laid, the harness fastening pieces are bent inward so that a large number of harnesses are pressed and held collectively in the duct. Shall be. According to this configuration, the tongue-shaped harness fastening piece integrally formed by sheet metal processing of the mounting metal can be slightly used during wiring work of the harness without using a separate clamp metal as in the conventional structure. A large number of harnesses laid in the duct of the mounting metal can be pressed down and held together by a simple operation of simply bending by hand. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the embodiments shown in FIGS. In the drawings of the embodiment, members corresponding to FIGS. 4 (a) and 4 (b) are denoted by the same reference numerals, and description thereof will be omitted. In other words, in the illustrated embodiment, the channel-shaped mounting metal 8 disposed behind the button case 7d of the push-button device 7 with the front panel 5a interposed therebetween has at least a duct portion at its end side (the side from which the harness 10 is drawn out). A tongue-shaped harness fastening piece 8b is formed to protrude from the upper edge of 8a. The harness fastening piece 8b is formed by pressing a thin steel plate and processing a sheet metal to form a mounting metal 8.
Shall be formed at the same time when fabricating. Note that the harness fastening pieces 8b may be dispersedly formed at several places in the longitudinal direction of the mounting metal 8. At the time of wiring work of the harness, the harness 10 connected to the harness terminal 7e of the push button device 7 via the connector 9 is laid along the inside of the duct portion 8a of the mounting member 8, and the above-described fastening is performed. The pieces 8b are pushed and bent in the direction of the arrow by hand, and a large number of harnesses 10 are pressed together and held inside the duct portion 8a. As described above, according to the structure of the present invention, a push button device for selecting a product of a vending machine mounted on the front of a display room for displaying a product sample is provided. Push-buttons, switch elements, a sheath-shaped button case with a printed circuit board attached, and a mounting plate that also serves as a harness duct are overlapped and fastened to the front and rear sides of the front panel. In the case where the corresponding harness is routed along with the inside of the mounting metal duct, a bendable tongue-shaped harness fastening piece is provided on the trailing edge side of the mounting metal duct,
By arranging the harness fastening pieces inwardly in a state where the harness is laid on the mounting bracket and holding a large number of harnesses in the duct collectively, thereby holding the harness.
Unlike the conventional structure, the tongue-shaped harness fastening piece formed on the mounting metal can be easily bent by hand just slightly by hand when wiring the harness without using a separate clamp metal fitting. A large number of harnesses laid inside can be pressed down and held together, thereby reducing the number of parts and the number of assembling steps as compared with the conventional structure, thereby reducing costs.
