Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plug for connecting a cigarette lighter power supply of an automobile, which can be stably and detachably inserted / coupled into a power hole of a cigarette lighter of the automobile and can be prevented from rattling after the insertion.

[0002]

[Prior art]

 Usually, most cars have a cigarette lighter inside. When the cigarette lighter is not used for igniting a cigarette, the power source of the cigarette lighter can be used as a driving source for other electric appliances by inserting the power source connecting plug into the power source hole of the cigarette lighter.

As shown in FIG. 5, the structure of a conventional cigarette lighter power supply connection plug is such that an end portion of a cylindrical plug body 90 is electrically contacted with a positive electrode in a power hole of the cigarette lighter. And a pair of elastic pieces 91 for making electrical contact with the negative electrode in the power source hole of the cigarette lighter on the outer peripheral surface near the end of the connection plug body 90.

[0004]

[Problems to be solved by the device]

 However, the size of the car cigarette lighter produced by each manufacturer is not fixed, so when the conventional power plug is inserted into the power hole of the cigarette lighter of a different car, it often does not fit.

Further, since the pair of elastic pieces 91 provided on the outer peripheral surface of the power supply connecting plug have elasticity, even if elastically deformable in a recoverable manner, only two points are held on the peripheral wall inside the power supply hole. Depending on what is done, the insertion state is not very stable.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a plug for connecting a cigarette lighter power supply of an automobile, which can be tightly inserted and fixed in a power supply hole of a cigarette lighter of a different size. To that end.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a fuse for electrically contacting a positive electrode of a cigarette lighter power supply at one end, and an elastic piece and a plurality of slots for electrically contacting a negative electrode of a cigarette lighter power supply on an outer peripheral surface. And a push-in tool having an insertion post that can be inserted into a slot provided on the outer peripheral surface of the plug body, and with the plug body inserted into the power hole of the cigarette lighter, By inserting and pushing the insertion post of the push-in tool into the slot provided on the outer peripheral surface of the plug body, the plug body can be tightly fixed to the power hole of the cigarette lighter.

Further, a taper surface that is inclined from the base portion to the end portion may be formed on the insertion column of the pushing tool.

[0009]

[Action]

 Since the present invention has the above-mentioned configuration, in the case of a cigarette lighter power supply hole having an inner diameter larger than the outer diameter of the flag body, the gap between the outer diameter of the plug body and the inner diameter of the power supply hole is The post is sealed by inserting it into a slot provided on the outer peripheral surface of the plug body. Therefore, the insertion state of the connection plug is stable, and it is possible to prevent the connection plug from coming off the power supply hole.

Further, if the insertion post of the push-in tool is provided with a tapered surface, the insertion end can be easily inserted because the tip is thin during insertion of the insertion post into the slot of the plug body. Further, since the tapered surface of the insertion pole has a degree of inclination, the insertion tightness of the plug in the power supply hole can be freely controlled depending on the degree of pushing of the pushing tool, which makes it suitable for use in various vehicles.

[0011]

【Example】

 Next, a preferred embodiment of the present invention will be described with reference to FIGS. The present invention mainly comprises a plug body 10 and a pushing tool 20, as shown in FIG.

A fuse 101 is provided at the end of the plug body 10 for making electrical contact with the positive electrode in the power source hole of the cigarette lighter, and the outer peripheral surface of the fuse 101 is electrically contacted with the negative electrode in the power source hole of the cigarette lighter. Is provided with an elastic piece 12 and a pair of slots 11 into which an insertion post 21 of the push-in tool 20 described below can be inserted are provided on the outer peripheral surface of the plug body 10. A grip portion 13 that is used for gripping and pushing is provided.

The push-in tool 20 is provided with two insertion columns 21 corresponding to the pair of slots 11 of the plug body 10, and the insertion columns 21 are provided with tapered surfaces 210 inclined from the base to the end. At the rear end of the push-in tool 20, a base portion used for a user's gripping and pressing operation is formed.

Further, as shown in FIGS. 2 and 4, the cross section of the slot 11 of the plug body 10 is formed in a substantially L shape, and the cross section of the bottom of the slot 11 is formed in an arc shape.

As shown in FIGS. 3 and 4, when the connection plug body 10 is inserted into the power hole 30 of the cigarette lighter, the fuse 101 at the tip of the plug body 10 electrically contacts the positive electrode at the back of the power hole 30, Further, the elastic piece 12 provided on the outer peripheral surface comes into electrical contact with the negative electrode in the power supply hole 30. At this time, if the insertion post 21 of the push-in tool 20 is pushed from the rear end of the plug body 10 along the slot 11 of the plug body 10, the plug body 10 is tightly closed by the closing action of the push-in tool 20. Can be fixed to.

Further, since the insertion post 21 of the push-in tool 20 is provided with the tapered surface 210 inclined from the base to the end, the insertion post 21 can be easily inserted during insertion into the slot 11 because the tip of the insertion post 21 is thin. In addition, the cross-section of the column 21 increases as the degree of indentation increases, so if the degree of indentation is adjusted appropriately, the plug body 10 can be stably fixed in the power supply hole 30 with an appropriate tightness. be able to.

[0017]

[Effect of device]

 Since the present invention has the above-mentioned configuration, if the inner diameter of the power hole of the cigarette lighter is larger than the outer diameter of the plug body, the plug body can be adjusted to a proper tightness by adjusting the insertion degree of the pillar. It can be stably and detachably connected to the power hole of the lighter, and it can solve the problem of rattling easily when the conventional connection is made. Further, as described above, since the slot of the plug body has a substantially L-shaped cross section, and the bottom of the slot has an arc shape, when the push-in tool 20 is pushed in, the pillar is inserted. Is easily inserted, and since the cross section of the slot is L-shaped, there is an effect that the column can be guided along the bottom of the slot.
