Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connector installed on a wall for connecting a two-way telephone.

[Conventional technology]

In this type of telephone connector, the cover plate 1 and the connector main body 2 are formed separately as shown in FIG. This is done by attaching the cover plate 1 to the connector main body 2 after attaching it to the opening formed in the wall surface (not shown). Conventionally, such connectors are
Since there is not enough space to slide the socket cover near the socket opening 2a of the connector body 2, the connector opening 1a of the cover plate 1
A socket cover 1b was attached to the bottom of the tank so as to be movable, and the socket cover 1b was configured to be able to be opened and closed. This is to prevent dust from adhering to the socket opening 2a of the connector main body 2 and causing conduction failure during plug connection.

Further, some connectors of this type have a built-in 08 circuit connected in parallel to a telephone line contact. This 08 circuit is recommended to be built in so that the telephone office can detect malfunctions in the telephone. For this reason, there are two types of telephone connectors: those that incorporate the 08 circuit and those that do not. Conventionally, this distinction has been made by displaying a message to that effect on connectors incorporating the 08 circuit.

[Problem that the invention seeks to solve]

In the conventional connector as described above, the cover plate 1 and the connector body 2 are formed separately, so when these are attached to a wall, the connector opening 1a of the cover plate 1 and the connector body 2 are formed separately. There is a problem in that the position of the socket opening 2a of the socket 2 may be misaligned, making it impossible to insert the plug. In addition, in conventional connectors, as shown in b-A, the built-in CR circuit was indicated by pasting a label on it, so the label peeled off and became indistinguishable from the outside, which hindered installation work. There was a risk of this happening.

The present invention solves the above-mentioned problems, and allows the plug to be inserted reliably, prevents dust from entering through the socket opening, and allows the presence or absence of a built-in 08 circuit to be indicated by a label. The purpose is to provide a connector that can be reliably confirmed without any trouble.

[Means for solving problems]

The configuration of the connector according to the present invention for achieving the above object of the present invention is such that a modular jack is attached to the front side and a terminal is attached to the back side, and the modular jack and the terminal are installed inside. The main body of the connector, which is wired by A socket cover that can be opened and closed by engaging, a back cover (=1 part) formed on the back side of the connector body, and a cover that is attached to the connector body so as to cover the terminals. This configuration includes a terminal cover and a terminal cover.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings.

1 to 4 show an embodiment of the connector according to the present invention, FIG. 1(A) is a front view with the socket cover closed, and FIG. 1(B) is a front view with the socket cover closed. Fig. 2 is a partially cutaway bottom view of the connector in the same embodiment, Fig. 3 is a side view of the same embodiment, and Fig. 4 is the same embodiment with the terminal cover removed. FIG.

In the figure, reference numeral 10 denotes a connector main body, and this connector main body IO is composed of a first connector main body 11 and a second connector main body 12, and has four hooks protruding in the front direction of the second connector main body 12.

A shaft 2 is attached to the corner (cover storage section side) at the end in the width direction.
1 is fixed, and this shaft 21 engages with rotation support part 18 to enable opening and closing. When the angle of approximately 90' is reached, the engagement between shaft 21 and rotation support part 18 is released, and the rotation support part 18 is disengaged. As shown in FIG. 2, a support protrusion 12 is formed integrally with the inner surface of the second connector main body 12 by moving in the vertical direction with respect to the cover storage part 16.
It is stored by being supported by d.

In addition, to close the socket cover 20, pull out the socket cover 20 stored in the cover storage part 1θ with your fingertips, engage @21 with the rotation support part 18, and then turn the socket cover 20 at an angle of approximately 80°. Modular jack 1
5 can be occluded. The socket cover 20 in this closed state is closed with moderation, and this is because a knee protrusion 22 is formed at the end of the socket cover 20 opposite to the axis 21, and when the socket cover 20 is closed, the opening/closing part 19 is closed. By engaging the engagement member 11 with the hole 19a, a reliable closed state can be maintained.

Furthermore, the socket cover 20 is formed with a notch 20a in the width direction so that a nail can easily fit therein when opening the socket cover 20, and correspondingly, a notch 11b is formed in the vicinity of the opening/closing part 19 of the first connector main body 11. is formed and is substantially flush with the opening/closing portion 13.

Therefore, since the socket cover 20 of this embodiment can be stored in the cover storage part 1G formed on one side of the modular jack mounting part 13, a cover storage part 1G is formed in the lower direction, and the socket cover 20 can be stored in this. Compared to the possible 17
Since ample space can be taken up for the storage mechanism, it becomes easier to mold, it can be formed into an hour wheel R structure, and the mold can be made at a lower cost. In addition, since the opening and closing operation is from the side, it becomes easier to open and close.

On the other hand, reference numeral 30 denotes a back cover mounting portion 12 that is opened and formed on the back side of the connector body 10, that is, on the back side of the second connector Kokyu 12.
This back cover 30 is provided with a confirmation window 31 for directly confirming from the outside that the CR circuit is built-in.

FIG. 5 is a partially cutaway bottom view showing a connector which is a modification of the storage means of the socket cover 20 in the embodiment described in F above. In the previously described embodiment, the socket cover 20 was manually stored, but in the modified example shown in FIG.
The socket cover 20 is interposed between the base end portion 20d and the support protrusion 12d, and the tension force of the tension spring 50 causes the socket cover 20 to
The structure allows for storage operations. With this configuration, the storage operation can be simplified, and the socket cover 20 can be stored and kept in a stable state without rattling.

Note that the present invention is not limited to the above embodiments,
For example, the connector body may use other engagement means to engage the first connector body and the second connector body.

〔Effect of the invention〕

As explained above, according to the connector according to the present invention, a modular jack is attached to the front side and a terminal is attached to the back side, and the modular jack and the terminal are connected internally. It can be stored in a cover storage part formed on one side of the connector main body and the modular jar mounting part, and can be engaged with a rotation support part provided in an opening of the cover storage part. a socket cover that can be opened and closed by the user; a back cover attached to a back cover attachment portion formed on the back side of the connector body; and a terminal cover attached to the connector body so as to cover the terminals. Therefore, the plug can be inserted reliably and easily, and dust can be prevented from entering through the socket opening, and children can be prevented from inserting their fingertips.

In addition, since it has an A lid, a back cover with a confirmation window is attached to the connector body with a built-in CR circuit, while a back cover with the confirmation window is attached to a connector body without a built-in CR circuit. By attaching the lid, the presence or absence of the -CR circuit can be easily confirmed.

Moreover, the same connector main body can be used regardless of the presence or absence of the CR circuit, and manufacturing can be simplified.

Furthermore, since the terminal cover is provided, there is no contact with the heat insulating material in the wall when the terminal cover is attached, and it is possible to prevent dust from adhering to the terminal cover.
