Description

TECHNICAL FIELD The present invention relates to a structure for supporting a connecting portion of a cord used in a communication device such as a telephone.

2. Description of the Related Art Examples of conventional cord connection structures for communication devices are shown in FIGS.
Shown in the figure. Although these figures show a telephone as an example of the communication device, the same connection structure is adopted in other communication devices such as a facsimile.

As shown in FIG. 2, the upper case 1 and the lower case 2 of the telephone
A bush 3 made of an elastic body is disposed so as to be sandwiched between the curls 4 and a curl cord 4 passes through the bush 3, and a core wire 5 is electrically connected inside the telephone.

Further, FIG. 3 uses a modular type connector. The modular type connector 6 is a connector consisting of a male side 7 and a female side 8. The cord 4 is connected to the male side 7, and the male side is actuated by the elastic claw 9 provided on the male side. 7 and the female side 8 are connected by a one-touch method. That is, when the male side 7 is inserted into the female side 8, the inclined portion of the claw 9 is pressed by the groove of the male side 8 to bend, and the step portion continuous to this inclined portion engages with the groove by snapping. Then the connection is made. When the connection is released, the claw 9 and the cord 4 are pinched with fingertips to disengage the stepped portion from the groove, and the male side 7 is pulled out. In this way, connection and disconnection are performed with one touch.

However, in the connection structure shown in FIG. 2, in order to connect or disconnect the cord 4, the upper case 1 and the lower case 2 of the telephone are disassembled by removing screws or the like. I had to. In the connection structure shown in FIG. 3, the modular type connector facilitates connection and disconnection of the cord 4, but the external force applied to the cord 4 is directly applied to the modular type connector. It was easy for abrasion of the electrical contacts and defective electrical connection to occur.

The present invention has been made in view of the above problems, and is provided with a structure in which connection and disconnection with a cord are easy, and an external force applied to the cord is difficult to be transmitted to the connector, and dust and dust do not enter the connector. An object is to obtain a cord connection device for communication equipment.

Means for Solving the Problems In order to achieve the above object, the present invention has a recess formed in a part of a communication device case, a female side is attached to the communication device case, and one end of the male side is attached to and detached from the female side. A modular type connector that freely fits and a cord is connected to the other end,
A lid that covers the concave portion and is attached and detached with a claw, and a pressing portion that is formed on both edges of the lid and the communication device case and holds the cord by sandwiching the cord are provided.

Effect The present invention has the above-described configuration, and the cord connected by the modular type connector is sandwiched and held by the pressing portion formed on the lid and the pressing portion formed on the edge of the recess of the case, and is added to the cord. External force is received by the pressing portion and is not directly applied to the modular type connector. Further, since the lid is simply fitted into the concave portion and disengaged with a single touch, and since the modular type connector is used as it is, connecting and disconnecting the cord can be performed easily without using a screw or the like. In addition, the modular type connector is covered with a lid to prevent dust and dirt from entering.

Example FIG. 1 shows a cross section of a telephone, which is one of communication devices. It should be noted that this figure is a portion of the handset of the telephone as in FIGS. 2 and 3 shown as the conventional example. The upper and lower cases 1 and 2 of the handset are fixed by screws or the like.
A concave portion 11 is provided at a portion where the upper case 1 and the lower case 2 are joined.
Are formed. The recess 11 has an L-shaped cross section as shown in the figure, and a modular type connector 6 is provided inside.
The female side 8 of is fixed. The curl cord 4 is connected to the male side 7 of the modular type connector 6, and the male side 7 is inserted and connected to the female side 8. A lid 12 is arranged so as to cover the recess 11. The lid 12 has an L-shaped cross section, and can be fitted into the recess 11 with one touch by a claw 13 shown in the figure and a claw not shown. Pressing portions 14 and 15 are formed on the edge of the upper case 1 and the edge of the lid 12, respectively, and hold the curl cord 4 therebetween.

Next, the procedure for connecting and disconnecting the cord 4 in this embodiment will be described. First, for connection, the female side 8 of the modular type connector 6 is incorporated into the case side in a state where the upper case 1 and the lower case 2 are fixed together by screws (not shown) or the like. The curl cord 4 is connected to the male side 7 of the modular type connector, the male side 7 is inserted into the female side 8, and the connection is made with one touch by the action of the claw 9 as in the conventional case. After that, the lid 12 is pushed from the direction A in the drawing with a fingertip to be fitted into the snapping to cover the recess 11. At this time, the two pressing portions 14 and 15 sandwich and hold the telephone 4 outside portion of the cord 4 which was previously connected. On the contrary, when the connection is released, the lid 12 is removed with a fingertip and the male side is pulled out from the female side of the modular type connector so that the claw 9 and the cord 4 are sandwiched.

As described above, according to the present embodiment, it is not necessary to use a tool such as a screwdriver at the time of connection and disconnection, and the external force applied to the cord 4 is supported by the two pressing portions 14 and 15, and the modular type connector 6 is directly connected. There is no transmission to. Further lid
The recess where the modular connector is placed by 12
Since 11 is covered, it is possible to prevent dust and dirt from entering the concave portion 11 and further the modular type connector 6. The two pressing portions 14 and 15 have a rounded shape so that the cord can be sandwiched and held in a wide area, and the cord 4 will not be broken even when receiving an external force. In the above embodiments, the recess 11 and the lid 12 have an L-shaped cross section, but in other embodiments, the recess may be a U-shaped recess and the lid may be a flat lid.

Effects of the Invention As is apparent from the above description, the present invention has the following effects.

(1) The conventional modular type connector can be used as it is, and the lid covers the recess by fitting into the recess, so that the cord can be easily connected and disconnected without using a tool.

(2) Since the lid covers the recess where the modular type connector is placed, it prevents dust and dirt from entering the modular type connector, and prevents contact failure of the connector due to these dust and dirt. it can.

(3) Since the cord is sandwiched and held by the pressing part formed on the case and lid, the external force applied to the cord is not directly transmitted to the modular type connector, and the contacts of the modular type connector are less likely to wear or have poor contact. it can.
