Description

[Detailed explanation of the idea] The present invention relates to a cigarette lighter.

The prior art will be explained with reference to FIGS. 7 and 8.
FIG. 7 is a schematic explanatory diagram of the conventional device, and FIG. 8 shows its mounting hole.

70 is a cigarette lighter attached to an instrument panel 71 located in front of the front seat of the automobile;
A plug device 72 is built in the inner case 73 and includes an ignition heater section 74. The inner case 73 has a tubular male screw portion 75 on the side opposite to the open end through which the plug device 72 enters and exits. Reference numeral 76 denotes an illumination ring which is externally fitted and engaged with the inner case 73, and when the illumination lamp 77 is turned on, the illumination portion 76' lights up. Reference numeral 78 denotes a female screw portion 7 whose open end abuts against the back surface of the instrument panel 71 and which screws into the male screw portion 75 of the inner case 73 on the opposite side of the open end.
This is an outer case equipped with 9. Reference numeral 80 is a power terminal fixed to the inner case 73, and reference numeral 81 is a ground terminal fixed to the outer case.

Cigarette lighter 70 on instrument panel 7
1, insert the inner case 73 with the lighting ring 76 engaged into the mounting hole shown in FIG. At the same time, the female screw portion 79 of the outer case 78 must be screwed into the male screw portion 75 of the inner case 73 from the back side of the instrument panel 71.

Therefore, it is time consuming and difficult to install the cigarette lighter by entering the back side of the instrument panel 71, which is already occupied by other equipment.

The present application was devised to solve the above problems, and includes a cylindrical outer case fixed to the back of the panel, a bimetallic holder disposed inside the outer case, and a bimetallic holder engaged with the holder. A cigarette lighter comprising a cylindrical inner case having an ignition heater part that glows red-hot; It is provided on the outer periphery of the open end and can pass through the mounting hole from the front side to the back side of the panel, and can come into contact with the back side of the panel at the periphery of the mounting hole by rotating around the axis of the mounting hole. a cylindrical outer case having a plurality of protrusions and a female screw portion on the inner periphery, and a male screw portion on the outer periphery that fits externally into the inner case and can be screwed into the female screw portion of the outer case. a lighting ring having a flange portion that cooperates with the protrusion to clamp the peripheral edge of the mounting hole; and a lighting ring that is provided on the peripheral edge of the mounting hole on the back surface of the panel and abuts against the protrusion to align the axis of the mounting hole. The gist of the present invention is a cigarette lighter characterized by being equipped with a stopper that restricts the rotation of the cigarette lighter.

According to the above configuration, the outer case is formed to be able to pass through the mounting hole from the front side to the back side of the panel, and the male threaded part of the lighting ring externally fitted and locked to the inner case is screwed into the female threaded part of the outer case. At the same time, since the periphery of the mounting hole can be held between the flange of the lighting ring and the protrusion of the outer case, the cigarette lighter can be mounted from the front side of the panel, making the work of mounting the cigarette lighter to the panel extremely easy. .

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

FIG. 1 is a schematic explanatory diagram showing one embodiment of the present invention, and FIG. 2 is an explanatory diagram taken in the direction of the arrows in FIG.

Reference numeral 2 indicates a panel such as an instrument panel located in front of the front seat of an automobile or a center console box located in front of the rear seat, on which a cigarette lighter 4 is fixedly arranged.

The cigarette lighter 4 includes an outer case 6 having a cylindrical appearance made of sheet metal as shown in FIG. A plug device 16 having an ignition heater installed therein is inserted through an opening 14 which is a mounting hole on the instrument panel 2 side of the inner case 10. Retained.

The outer case 6 has a female screw 18 formed near the open end on the side of the instrument panel 2, and a flange 20, which is a projection bent radially outward, at the open end.
It is in contact with the back surface 22.

24 is a lighting ring made of transparent colored acrylic, as shown in FIG.
6, and a flange 32 formed at the open end of the main body 28 and abutting against the surface 30 of the panel 2. It is externally fitted and engaged. A pair of slits 33, 33 are formed on the surface of the flange 32 to enable engagement with a tool.

The opening 14 of the instrument panel 2 is
As shown in a perspective view of the mounting hole seen from the back side of the instrument panel in FIG. A stopper 38 that projects inward is provided on the back surface of the portion 34. The flange 20 of the outer case 6 has a larger diameter than the small diameter portion 34 and a smaller diameter than the large diameter portion 36, and the flange 20
are provided in the same phase as the large diameter portion 36. Further, the flange 20 is formed so that the circumferential width X of the flange 20 is smaller than the circumferential width Y of the large diameter portion 36 so that the flange 20 is inserted from the surface 30 side of the panel 2. Further, the flange 32 of the illumination ring 24 is formed to have a larger diameter than the large diameter portion 36.

40 is a power terminal connected to a bimetallic holder 12 fixed to the inner case 10, and 42 is a ground terminal fixed to the inner case 10 by a rivet 8.

44 is an opening formed in the cylindrical end surface 46 of the outer case 6, and 48 is an opening formed in the inner case 10 corresponding to the opening 44.

50 is a terminal case, which includes a terminal 52 connected to the power terminal 40 and a terminal 5 connected to the ground terminal 42.
4 and lighting terminals 56 and 58, and an illumination lamp 60 that is connected and fixed to the lighting terminals 56 and 58 is integrally provided inside. The illumination light 60 is located close to the opening 44 of the outer case 6 and the opening 48 of the inner case 10 in the terminal case 50, and passes through the openings 44 and 48 to the inner case 10.
0 and the illumination ring 24, and the flange 32 portion of the illumination ring 24 is made to emit light. It is preferable that the outer size of the terminal case 50 is smaller than the inner size of the small diameter portion 34 of the opening 14.

The cigarette lighter 4 loosely connects the illumination ring 24 that is externally engaged with the inner case 10 to the outer case 6.
The flange 20 of the outer case 6 is inserted through the large diameter part 36 of the opening 14, and the flange 32 of the illumination ring 24 is inserted into the instrument panel 2 from the surface 30 side. 3, the opening 14 is opened so that the flange 20 abuts the protrusion 38 at that position, as shown in FIG.
The illumination ring 24 is further rotated with the outer case 6 being prevented from rotating.

By rotating the illumination ring 24, the panel 2 is held between the flange 32 of the illumination ring 24 and the flange 20 of the outer case 6, and the outer case 6
hold firmly.

A slit 33 is formed in the illumination ring 24, and a tool is appropriately engaged with the slit 33 to rotate it.

Therefore, according to this embodiment, the cigarette lighter 2 can be attached to the panel 2 only from the front surface 30 side of the panel 2, and the work efficiency is improved.
