Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a jack for a plug-in telephone using a modular plug.

Current plug-in telephone cords have either a three-point plug or a modular plug connected to the end of the cord. These plug-in telephones are generally
It is used by inserting a plug attached to the end of a cord into a jack that is attached to a wall or buried, and the present invention relates to this jack.

[Conventional technology] Conventional telephones have a 3-point plug (NTT standard)
Recently, modular plugs (FCC standard), which are smaller than these three-point plugs, have also come into use, and are becoming popular in Japan as well.

In particular, with the liberalization of sales of telephones, the plugs of telephones on the market will shift from the conventional three-point plug to modular plugs that are smaller, have locks, and are easier to handle.

However, in households that already use plug-in telephones, three-point jacks are being installed.

[Problem that the invention aims to solve] In order to use a plug-in telephone with the latest modular plug in an already installed three-point jack, it is necessary to replace the conventional three-point jack with a modular jack. Must be replaced. However, this replacement work is legally prohibited for non-qualified personnel to carry out, and the work is expensive and requires a long waiting time, so it is difficult to install a modular plug. This was a major obstacle in installing a new telephone.

[Means for solving the problem] The present invention was made to solve this problem, and consists of a three-point plug attached to the base and a modular plug inserted parallel to the surface of the base. However, a modular jack is attached to the base so that the modular plug can be inserted so that the surface of the lock lever of the modular plug is perpendicular to the base.

[Function] With this, an already installed three-point jack can be converted into a modular jack, and the protrusion from the wall is small, and the lock
Since you won't accidentally press the surface of the lever, the modular plug won't fall out, and when it comes to removing the modular plug, it's easy to remove because the surface of the locking lever is positioned for easy handling. It is something that can be extracted.

[Example] Figure 1 shows an example of the present invention, and Figure 2 shows the first example.
The one shown in the figure with the cover removed is the third
The figure shows a bottom view.

In FIG. 1, 10 is a base, 11 is a cover, and 12a is one of three three-point plug pins 12a, 12b, and 12c forming a three-point plug.
20 is a modular jack, 21 is a locking groove, 30 is a modular plug inserted into the modular jack 20, 31 is a lock when the modular plug 30 is inserted into the modular jack 20, and a lock groove when the modular jack 20 is removed. 3 is a lock lever for releasing the lock, and 32 is a telephone cord connected between the telephone and the modular plug 30.

In Fig. 2, 13a and 13b are cords,
A modular jack 20 is connected to three-point plug pins 12a and 12b, respectively.
Here, the three-point plug pins 12b and 12c are 1
It consists of two pieces of metal. 14 is attached to the cover 1 from the back side of the base 10 with screws 15 shown in FIG.
1 is a screw hole for attaching the screw hole, and 22 is a contact for the modular jack 20.

In Figures 1 and 2, bases 10 and 3
The three-point plug pin 12 of the book is a conventional three-point plug (NTT standard), and the modular jack 20 is also an existing one (FCC standard).

The modular jack 20 is designed so that the insertion direction of the modular plug is perpendicular to the plane of the base 10, rather than parallel to the plane of the base 10 as shown in FIG.
If it is mounted upward, it will protrude a lot from the wall, making it extremely inconvenient to use.

In FIG. 1, the modular jack 20 is installed so that the lock lever 31 is on the front side, but on the other hand, the modular jack 20 is installed so that the lock lever 31 is on the opposite side after being turned 180 degrees. may be provided. but,
If the lock lever 31 is placed on the upper side, there will be more chances of touching the lock lever 31 by mistake, which increases the possibility that the modular plug 30 will fall off, which is not preferable. On the other hand, if the lock lever is placed on the lower side, this lock lever 31 will be located between the modular plug 30 and the wall surface, so operate the lock lever 31 to release the lock. This is not desirable because it makes it difficult to do so.

[Effects of the invention] As is clear from the above explanation, if the jack according to the invention is used, there is no need to replace the existing three-point jack with a modular jack, so no construction work is required. This saves costs and eliminates the need for waiting time for construction work.

Furthermore, the insertion direction of the modular plug and the orientation of the locking lever have been adjusted to ensure the most reliable use and ease of operation.
Since it is a combination of a base with pins and a modular jack, the effects of the present invention are extremely large.
