Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for an automobile cigarette lighter.

As is well known, automobile cigarette lighters are attached to instrument panels.

The mounting structure generally employed in the past is as follows.

That is, insert the socket of the cigarette lighter into the mounting hole of the panel from the front of the panel, bring the collar provided around the outer end of the socket into contact with the periphery of the mounting hole, and
Most of the socket is made to protrude to the back side of the panel, a cylindrical case is placed on the protruding part on the back side of the panel, and the threaded bottom of the socket and the threaded bottom of the case are screwed together and tightened, The periphery of the mounting hole of the panel is held between the flange of the socket and the periphery of the upper end of the case.

Since the conventional mounting structure is as described above, there is a drawback that the mounting work cannot be performed only from the front side of the panel, resulting in poor work efficiency.

The present invention was developed in view of these conventional drawbacks, and provides a new mounting structure that can improve work efficiency by performing all mounting work on a cigarette lighter panel from the front of the panel. It is.

The present invention will be specifically described below with reference to the illustrated embodiments.

As shown in Figures 1 and 2, this mounting structure consists of a socket 4
A cigarette lighter, into which a plug 2 is removably inserted, is inserted and fixed into a mounting hole 1a of a panel 1 via a synthetic resin cylindrical holder 6 fitted around the outer periphery of a socket 4.

As shown in Fig. 1.2.3, the holder 6 has a flange 6a on the outer circumference of the outer end of the cylindrical main body 6f, and a pair of U-shaped flange 6a on the cylindrical main body 6f itself. shaped notches 6d, 6d
' are provided to form radially flexible locking pieces 6b, 6b.

Each of the locking pieces 6b, 6b is formed to extend from the inner end 2 to the outer end of the holder 6, and has a roughly hemispherical projection on the radially inner side of its free end. 6C
t 6 e' and a free end surface 6g.

6g is formed into a flat surface.

This free end face is 6g. The distance between the surface 6g and the inner surface 6h of the flange 6a is slightly larger than the thickness of the panel 1.

Further, the holder 6 includes a protrusion 6e on the inner surface of the cylindrical main body 6f.

On the other hand, the inner diameter of the mounting hole 1a of the panel 1 is slightly larger than the outer diameter of the cylindrical main body 6f of the holder 6.

The holder 6 having the above structure is installed at a predetermined incompletely inserted position on the outer periphery of the socket 4 before the cigarette lighter is attached to the panel 1.
It is forcibly inserted at position 1, where the outer end surface of holder 6 maintains a constant distance from the edge of a (the positional relationship between socket 4 and holder 6 is the same as that shown in Fig. 1). ), in this state, each of the locking pieces 6b, 6b
Holes 4b, 4b into which the protrusions 6c, 6c: 6e fit.

4c is provided on the cylindrical surface of the socket 4.

Further, not only the socket 4 but also the outer sleeve 5 of the plug 2 that slides in contact with the cylindrical surface of the socket 4, specifically the ash guard, have recesses 5b and 5b' recessed radially inward.
is formed.

Therefore, in this state, each locking piece 6b of the holder 6
, 6b exist on the same circumferential surface as the outer circumferential surface of the cylindrical main body 6f.

Furthermore, another hole 4c is provided in the cylindrical surface of the socket 4 adjacent to the hole 4c.

Further, the ash guard 5 has a flange 5a around its outer end, and this flange 5a engages with the flange 4a of the socket 4.

3 is the plug knob. As described above, the cigarette lighter with the holder 6 fixed to the outer periphery of the socket 4 is inserted into the mounting hole 1a of the panel 1 from the front side of the panel as shown in FIG. contacts the outer surface of panel 1.

Next, when the knob 3 is forcibly pressed further, the plug 2
and the socket 4 try to move inward integrally with respect to the holder 6.

Then, the protrusions 6c y 6c' of each locking piece 6b, 6b' of the holder 6 will fit into each hole 4b, 4b' of the socket 4.
is pushed radially outward by the surrounding wall of
The free end of each locking piece 6b, 6b is bent so that its free end surface 6d, 6d' just comes into contact with the inner surface of the panel 1.

FIG. 2 shows a state in which the plug 2 and socket 4 are completely pushed in and the flange 4a of the socket 4 is locked to the flange 6a of the holder 6.

As shown in the figure, in this state, the holder 6
Each locking piece 6b.

The protrusions 6c and 6c of 6b completely fit into the hole 4b of the socket 4.
, 4b and comes into contact with the cylindrical surface of the socket 4, while
The protrusion 6e comes out of the hole 4c and fits into another hole 4c.

Therefore, each locking piece 6b. The free end of 6b' is kept in the outwardly bent state 11.

Further, the protrusion 6e engages with the inner periphery of the hole 4c, and the socket 4
is prevented from being removed from the holder 6.

Therefore, the socket 4 of the cigarette lighter is fixed to the mounting hole 1a of the panel 1 via the holder 6 so as not to be movable in the axial direction.

In the above embodiment, the outer sleeve 5 of the plug 2 also includes:
Although recesses 5b and 5b were provided into which the protrusions 6c and 6c of the locking pieces 6b and 6b of the holder 6 were fitted, the thickness of the socket 4 was sufficiently thick and the protrusions 6c+6c were inserted into the outer sleeve 5.
If it does not reach , it is not necessary to provide such recesses 5b and 5b.

In addition, in the above embodiment, the cylindrical main body 6f of the holder 6 is provided with a protrusion 6e, and by fitting the protrusion 6e into the hole 4c or 4c of the socket 4, it is possible to prevent the socket 4 from being pulled out from the holder 6. However, this objective can also be achieved by, for example, configuring the outer diameter of the cylindrical surface of the socket 4 and the inner diameter of the cylindrical main body 6f of the holder 6 in a tight fit relationship. obtain.

As described in detail in the embodiments above, the mounting structure of the automobile cigarette lighter according to the present invention employs a holder that can be inserted into the mounting hole of the panel from the front of the panel instead of the conventional socket mounting case. The holder that holds the cigarette lighter is securely fixed to the wall surrounding the mounting hole by simply fitting the holder around the socket and then forcing the cigarette lighter into the panel mounting hole from the front of the panel. Therefore, the intended purpose of the present invention can be achieved.
