Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a car plug which uses a jack portion of a cigarette lighter provided in a cabin of an automobile, replaces the cigarette lighter in the jack portion, and inserts a plug to take out a power source.

[0002]

[Prior art]

 The inside diameter of the jack part of the cigarette lighter installed in the cabin of a car differs depending on the car model.

[0003] Therefore, when a car plug, which is sold on a different sales route from an automobile, is inserted into the insertion port of this cigarette lighter as a car article, there is looseness between the inner peripheral surface of the insertion port and the car plug. Car plugs are provided with measures against this, as they may occur or they may become too tightly fitted.

As a countermeasure against this, there is a means disclosed in Japanese Utility Model Laid-Open No. 6-64384. As shown in FIGS. 1 and 2, this means is a part of the peripheral wall of the body 1 of the car plug A formed in a tubular shape, and the terminal portion of the elastic terminal plate 2 assembled to the body portion of the body 1. A cutout window hole 3 is formed at an intermediate portion in the circumferential direction between the terminal 20 and the terminal 20, and one end side is connected to the peripheral wall of the body 1 and the other end side is outside the peripheral wall of the body 1 in the window hole 3. An elastic arm 40 that moves inward and outward relative to the surface is provided, and a protrusion 41 that radially projects from the outer surface of the peripheral wall of the body 1 is provided on the outer surface side at the other end side of the elastic arm 40. When the body 1 is inserted into the insertion port 5 of the cigarette lighter provided in the cabin of the automobile as shown in FIG. 5, it is attached to the body of the body 1 with respect to the inner peripheral wall of the insertion port 5. The terminals 20 and 20 of the elastic terminal plate 2 and the projections 41 and 41 of the elastic arm 40 are elastic. Even if the inner diameter of the insertion port 5 is larger than the outer diameter of the body 1 of the car plug A by sexually pressure-contacting, there is no backlash. There is.

[0005]

[Problems to be solved by the device]

 The above means is designed to have a large inside diameter of the cigarette lighter outlet 5, and is applicable to the outlet 5 of a cigarette lighter for European cars, which has a large inside diameter. However, it is not applicable to Japanese cars, which have a slightly smaller inner diameter than that of European cars, and when the body 1 is inserted into the insertion port 5, the elastic arm The protrusions 41 provided on the 40 cause problems such as hindering the insertion operation, and the cord 6 coming out at the time of withdrawal due to excessive insertion.

The present invention has been made in order to solve the above-mentioned problems that have occurred in the conventional means, and is intended to be used as a cigar lighter insertion port of a European car in which the inner diameter of the insertion port is formed to be large. The body of the car plug should be inserted into the insertion port of the cigarette lighter of a Japanese car whose inner diameter is slightly smaller, and in such a state that they fit snugly, and It is an object of the present invention to provide a new means by which the operation of inserting / removing the body into / from the insertion port can be performed lightly.

[0007]

[Means for Solving the Problems]

 In the present invention, as a means for achieving the above-mentioned object, a car body for taking out a power source, in which a tubular body 1 is removably inserted into an insertion port 5 of a cigarette lighter provided in a cabin of an automobile. In the plug A, a notch window hole 3 is formed in a part of the peripheral wall of the body 1 at an intermediate portion in the circumferential direction of the body 20 between the terminal portion 20 of the elastic terminal plate 2 assembled to the body 1 and the terminal portion 20. Then, inside the cutout window hole 3, there is provided a pressure contact member 8 which is connected to the peripheral wall of the body 1 at one end side by a freely bendable arm portion 80 and whose other end side is moved in the radial direction with respect to the peripheral wall of the body 1. The surface is installed so as to be aligned with the outer diameter of the peripheral wall of the body 1 or located inside the outer diameter in a normal state. Inside the body 1, the inner surface of the pressure contact member 8 is located at the inner position of the pressure contact member 8. Away from the pressure contact member The is to raise the car plug made by instrumentation set the switching cam 9 switches to a to state extruded on the outer surface side of the body 1.

[0008]

[Action]

 In the means of the present invention configured as described above, the pressure contact member 8 arranged in the notched window hole 3 provided in a part of the peripheral wall of the body 1 and movably provided in the radial direction of the body 1 is provided in the body 1. The outer diameter of the body 1 is set to a position where the outer surface is aligned with the outer surface of the peripheral wall of the body 1 or a position closer to the inner side than the outer surface of the peripheral wall when it is free from the switching cam 9 provided on the. It will be adapted to small-diameter type inlets that match the inner diameter. Further, when the radially movable pressure contact member 8 is pushed out from the inner side by the switching cam 9 whose operating position is changed, the outer surface of the pressure contact member 8 is extended to the outside from the outer surface of the peripheral wall of the body 1. As a result, the outer diameter of the body 1 is expanded by an amount corresponding to the protrusion of the pressure contact member 8, so that the insertion port of a type having a slightly larger inner diameter can be adapted.

From this fact, the outer diameter of the body 1 is expanded and contracted by the operation of the pressure contact member 8 which is switched between the extended position and the retracted position by the switching operation of the switching cam 9, which is often caused in a European vehicle. You can fit it into both the outlet of a cigarette lighter with a slightly thicker inside diameter and the outlet of a cigarette lighter with a slightly smaller inside diameter that is often found in ordinary Japanese cars. In addition, it is easy to insert and remove, and you can do it smoothly.
