An object of the present invention is to provide a cable removal prevention structure for reliably
preventing a cable member from coming off with respect to a cable member provided with a rodlike plug. A cable member comprising a cable having an electronic component at one end and a
rod-like plug attached to the adapter at the other end, and one end attached to the attachment
portion of the adapter provided in the vicinity of the plug connection portion And a pullout
prevention member whose other end is attached to the cable of the cable member, wherein the
length of the pullout prevention member is shorter than the length of the plug. [Selected figure]

Cable disconnection prevention structure
[0001]
The present invention relates to a structure for preventing the disconnection of a microphone
cable or the like connected to an electronic device such as a wireless device.
[0002]
Heretofore, this type of cable retaining structure prevents the removal of the plug against pulling
of the cable by connecting the housing and the microphone cable with an eggplant ring or the
like.

FIG. 10 shows a conventional cable disconnection prevention structure.
In FIG. 10, 11 is a hook and fixed to the housing 12.
A jack 13 is provided in the housing 12. Reference numeral 14 denotes a ring, which is passed
through the cable 15 and connected to the eggplant ring 16. An L-shaped plug 17 is provided at
the end of the cable 15.
[0004]
Next, the operation of the above conventional example will be described. In the above-described
conventional example, when the cable 15 is pulled, the eggplant ring 16 is fixed by the hooking
fitting 11 provided in the vicinity of the jack 13 by the connection means such as the ring 14
passed through the cable 15. As described above, according to the conventional example, even if
the cable 15 is pulled, the ring 14 and the ring ring 16 passing through the cable 15 are
restricted in tension by the hooks 11, and the plug provided at the tip of the cable 15 Even if 17
is pulled, it does not come off.

[0006]
However, in the above-described conventional example, an L-shaped plug is targeted, and it is
difficult to sufficiently prevent the rod-like plug from coming off.
Also, no consideration has been given to a plurality of cable members.
[0007]
The present invention solves the above problems, and a cable member comprising an electronic
component at one end and a rod-like plug attached to the adapter at the other end is provided in
the vicinity of the connection portion of the plug. And a restriction member attached to the

[0011]
In FIG. 2, in the microphone adapter (first electronic component) 20, the connection jack 22 for
the wireless device body is attached to one end of the cable 21, and the adapter body 23 is
attached to the other end.
The adapter main body 23 is provided with a mounting portion 24 for mounting a ball chain
(first regulating member) 35 in the vicinity of the main body jack 25.

The one end of the ring portion (third regulating member) 31, the eggplant ring (fourth
regulating member) 32, and the cable (second regulating member) 33 are connected by the
coupling portion 34. There is.
A ball chain (first regulating member) 35 is connected to the other end of the cable (second
regulating member) 33.
The first cable member 40 includes a first cable 42 in which a microphone (first electronic
component) 45 which is an electronic component and the rod-like first plug 41 are connected, a
rod-like first plug 41 and a first cable 42. The connection cable 43 is connected to the jack 44 of
Further, the second cable member 50 is a second cable 52 connecting the microphone (second
electronic component) 53 and the second rod-like plug 51 connected to the first jack 44 of the
first cable member 40. It consists of
[0013]
Next, a method of assembling the cable slip prevention structure will be described with reference
to FIGS. 3 to 5.
[0014]
In FIG. 3, first, the ball chain 35 is removed from the ball chain connector, passed through the
attachment portion 24 of the adapter 20, and the ball chain 35 is attached to the ball chain
connector.
Next, the first rod-like plug 41 of the first cable member 40 is allowed to pass through the ball
chain (first regulating member) 35, and the first jack 44 also receives the ball chain (first
regulating member) 35. Let it pass. At this time, only the first cable 42 passes through the ball
chain (first regulating member) 35.
[0015]

Then, as shown in FIG. 4, the first plug 41 is connected to the main body jack 25 of the adapter
main body 23. Thereafter, the eggplant ring (fourth regulating member) 32 of the retaining
member 30 is attached to the connection cable 43 at the base of the first jack 44.
[0016]
As shown in FIG. 5, the second plug 51 of the second cable member 50 is allowed to pass
through the ring of the ring portion (third regulating member) 31 of the retaining member 30.
Then, as shown in FIG. 6, by connecting the second plug 51 and the first jack 44, the first cable
member 40 and the second cable member 50 are connected.
[0017]
By assembling in this manner, it becomes as shown in FIG. 1 and is completed. FIG. 7 is a
perspective view showing the dimensional relationship of each part in FIG.
[0018]
Referring to FIG. 7, according to the total length “A + F + C” of the first plug 41, the first jack
44, the second plug 51 and the second cable 40, the first detachment preventing member and
the second detachment preventing member When the second cord 52 is pulled, a force acts on
the first plug 41 in a direction to press it on the adapter body 23 and the second The force acts
on the plug 51 in the direction of pressing it on the jack 44, and each of the plugs 51 is
connected more firmly, and it is possible to prevent a plurality of cable members from coming
off. FIG. 8 is a perspective view showing the dimensional relationship of each part corresponding
to claim 1. In FIG. 8, the first plug 41 and the ball chain (first regulating member) 35 are
attached to the adapter body 23, and the first cord 42 is passed through the ball chain (first
regulating member) 35, Since the length "B" of the ball chain (first regulating member) 35 is
shorter than the length "A" of the first plug 41, when the first cord 42 is pulled, the first plug The
force 41 acts on the adapter body 23 in the direction to press it, so that the connection is made
more firmly, and the first plug 41 can be reliably prevented from coming off the adapter body
23. FIG. 9 is a perspective view showing the dimensional relationship of each part corresponding
to claim 2. In FIG. 9, the first jack 44 and the second plug 51 are connected, and an eggplant ring
(fourth regulating member) 32 is attached to the root of the first jack 44, and an eggplant ring

(fourth regulating member) 32 And the second cable 52 through the ring portion (third
restricting member) 31 connected through the connecting portion 34, the total length “C of the
first jack 44 and the second plug 51 Therefore, when the length of the total length “D” of the
third restricting member 31 and the fourth restricting member 32 is shortened, the third
restricting member portion is pulled when the third cord 52 is pulled. The first jack 44 and the
second plug 51 are held between the third control member 32 and the third restricting member
32, and the first jack 44 and the second plug 51 never come out of the ring portion 31. Have the
effect. Further, in the detachment prevention structure of the present invention, since two cable
members are connected in series, only one detachment prevention member 30 needs to be
attached to the adapter main body 23, which has an effect of saving a space.
[0019]
Further, the breaking force of the cable of the cable member is made larger than the breaking
force of the second slip preventing member, and the breaking force of the second slip preventing
member is made larger than the breaking force of the first slip preventing member. Before the
cable is broken, the disconnection prevention member is broken and the cable member is pulled
out of the adapter, so that it is possible to avoid the disconnection of the cable member.
[0020]
INDUSTRIAL APPLICABILITY The present invention can be used for retaining a cable or the like
used for two cable members connected to an electronic device such as a wireless device.
