Description

[Detailed Description of the Invention] The present invention relates to a connector for a cigarette lighter.

Conventionally, as disclosed in Japanese Utility Model Application No. 54-179639, for example, a cigarette lighter has been fixed to a mounting hole in an instrument panel located in front of the driver's seat of an automobile. A cigarette lighter consists of a cylindrical outer case made of sheet metal and an inner case disposed within the outer case. The inner case also has a lighter plug that is inserted and held through an opening on the instrument panel side and ignites a cigarette, a power supply terminal that supplies current to the lighter plug, and a male screw part on the opposite side of the inner case from the opening. It is equipped with Further, a colored light-transmitting ring having a flange that abuts the outer peripheral edge of the mounting hole on the panel surface is fitted onto the outer periphery of the opening of the inner case. Further, the flange of the inner case opening is in contact with the outer peripheral edge of the outer fitting hole of the colored transparent ring.

In addition, the outer case has an open end that contacts the outer peripheral edge of the mounting hole of the instrument panel and the back surface of the panel when the inner case is inserted, and a male screw portion of the inner case at the opposite end to the open end. A female screw portion that is screwed together with the female screw portion, and a colored transparent ring, a light bulb that illuminates the inside of the inner case, and a socket that is electrically connected to the light bulb through a hole provided between the open end of the outer case and the female screw portion. have. The socket is designed to be connected separately from the power terminal for the lighter plug.

Then, insert the inner case fitted with the colored transparent ring from the front side of the mounting hole, screw the outer case from the back side of the mounting hole, and attach the instrument panel between the colored transparent ring and the open end of the outer case. What is held between the parts is disclosed.

Therefore, when making an electrical connection to the cigarette lighter, the power terminal for the lighter plug and the socket must be connected separately, and it requires skill to connect each part securely to hard-to-see parts, and it is difficult to connect them securely. It also has the problem that it is difficult to confirm whether it has been completed.

The present application solves the above-mentioned problem, and provides a connector for electrical connection with an automobile cigarette lighter, in which a power terminal at the rear end of the cigarette lighter is engaged with the inside of the connector body made of an electrically insulating material that comes into contact with the rear end of the cigarette lighter. A first power terminal that supplies power to the cigarette lighter, a light emitter that illuminates the cigarette lighter, and a second power terminal that electrically connects the light emitter and supplies power to the light emitter and electrically grounds the light emitter. According to the present invention, the terminal for electrical connection to the cigarette lighter, the lighting lamp, and its wiring are integrated by the connector. The wire can be connected easily and reliably even in a place where the operator cannot see, and the wire connection operation only needs to be done once, which has the effect of improving work efficiency.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

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 a cylindrical outer case 6 made of sheet metal, an inner case 10 built into the outer case 6, and a bimetallic holder 12 disposed inside the inner case 10 to form a current-carrying terminal.
A plug device 16 having an ignition heater installed therein is inserted and held from an opening 14 of the inner case 10 on the side of the instrument panel 2.

As shown in FIG. 5, the outer case 6 has a female screw 18 formed near the open end on the side of the instrument panel 2, and further has a flange 20 extending outward at the open end so as to connect to the back surface 22 of the instrument panel 2. are in contact.

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 to abut against the surface 30 of the instrument panel 2. It is externally engaged with the part. A pair of slits 33, 33 are formed on the surface of the flange 32.
is formed to enable engagement with a tool.

The opening 14 of the instrument panel 2 is
As shown in the perspective view of the back side of the instrument panel in FIG. 4, a circular small diameter portion 34 and a large diameter portion 36
are mutually formed, and a protrusion 38 protruding inward is provided on the back surface of the small diameter portion 34.

Further, the mutual dimensional relationship between the opening 14 of the instrument panel 2 and the flange 20 of the outer case 6 is as shown in FIG. 3, as shown in FIG. Further, the flange 20 is formed so that the circumferential width X is smaller than the circumferential width Y of the large diameter portion 36 so that the flange 20 is inserted from the front surface 30 side of the instrument 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.

As shown in FIG. 7, the connector includes a terminal case 50, a terminal 52 connected to the power supply terminal 40,
It has a terminal 54 connected to the ground terminal 42 and illumination terminals 56, 58, and an illumination lamp 60, which is a light emitting body, is connected and fixed to the illumination terminals 56, 58, and 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 is connected to the inner case 10 through the openings 44 and 48.
The interior and the illumination ring 24 are illuminated, 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 is inserted from the surface 30 side of the instrument panel 2 with the illumination ring 24 externally fitted and engaged with the inner case 10 loosely screwed into the outer case 6, and inserted into the flange 20 of the outer case 6. is inserted through the large diameter portion 36 of the opening 14, and when the flange 32 of the illumination ring 24 comes into contact with the surface of the instrument panel 2, it is moved around the axis 0 of the opening 14 so that the flange 20 comes into contact with the protrusion 38 at that position. and further rotate the outer case 6.
The illumination ring 24 is rotated in a fixed state.
A slit 33 is formed in the illumination ring 24,
A suitable tool is engaged with the slit 33 and rotated.

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.

Therefore, according to the above embodiment, the cigarette lighter 2
Since the illumination light 60 and the illumination terminals 56 and 58 for the illumination light 60 are integrally installed inside the terminal case 50 which has the terminals 52 and 54 connected to the terminal case 50, the terminal case 50 is connected to the cigarette lighter 2 with one operation. By attaching it, all electrical wiring can be done, resulting in excellent workability.

Further, according to this embodiment, the cigarette lighter 2 can be attached to the instrument panel 2 only from the surface 30 side of the instrument panel 2, resulting in improved workability.
