Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a relay terminal board.
The present invention relates to a relay terminal board suitable for indoor wiring of telephone lines, etc.

(Prior Art) FIG. 8 is a perspective view showing an example of a terminal board used for relaying a conventional telephone line.
An example of a terminal board that relays and connects a core cable and a 4-core device cord of a telephone is shown. In FIG. 8, a female connector 2 is attached to one end of the base member 1, and the female connector 2 is formed so that a male connector (not shown) connected to the end of the cable core wire can be removably fitted into the connector. An insertion opening 3 is formed at the end for inserting the end of the four-core cord of the telephone. One end of each contact pin CP of the female connector 2 is bent within the fitting part so as to be elastically displaced in accordance with the mating connection of the male connector, and the other end is embedded in the base part 21 of the female connector 2. ing. Each other end of the contact pin CP is connected to the other end of a lead wire 5, the other end of which is connected to a screw tip 4. Further, two terminal fittings 6 as shown in FIG. 9 are arranged on each side of the base member 1, and are fixed to the base member with screws 7 together with screw-fastening tips 4. In addition, the terminal fitting 6 shown in FIG.
is the shape of the terminal fitting 6 on the opposite side in FIG. The end of the four-core cord of the telephone is connected to the terminal fitting 6.
It will be connected to the protrusion piece 61 of. Connect the end of the 4-core cord of the telephone to the protruding piece 61 of the terminal fitting 6.
After being connected to the base member 1, the upper part of the base member 1 is covered with a cover, which is not shown.

(Problems to be Solved by the Invention) However, according to such a conventional configuration, it is difficult to attach the female connector 2 to the base member 1 and connect the lead wire 5 to the end of the contact pin CP of the female connector 2.
The terminal fittings 6 and lead wires 5 must be connected to the base member 1, and the screw tips 4 of the lead wires 5 must be fixed with the screws 7. These assembly operations require a considerable number of man-hours. The number of assembly steps increases in proportion to the number of core wires, which is a cause of high costs. Further, a space must be secured for fixing the terminal fitting 6 and the screwing tip 4 of the lead wire 5 with the screw 7, making it difficult to downsize the device. Also, the number of parts is relatively large.

The present invention was devised in view of the above-mentioned problems, and its purpose is to realize a relay terminal board that has fewer parts than conventional devices, can be easily assembled, and can be made smaller. be.

(Means for Solving the Problems) The present invention which solves the above-mentioned problems is such that the male connectors connected to the ends of the cable core wires are formed so as to be removably fitted together, and the ends protrude outside. A female connector having a contact pin formed as shown in FIG. A terminal fitting having a connecting part to which a cable core wire is connected on the side thereof and a mounting part of the female connector are integrated, and a first protrusion body is arranged to hold each bent side of the terminal fitting. A second pair of protrusions are provided in a direction substantially orthogonal to each other, and the pair of protrusions that sandwich the bent side on which the kerf is formed has a groove in which the end of the contact pin of the female connector engages. A base member having a base member formed thereon, a pressing member having a hole for protruding the end of the connecting portion to which the cable core wire of the terminal fitting is connected and pressingly supporting the terminal fitting, and a pressing member containing these respective constituent members. and a cover attached to the base member.

The terminal fitting 200 is inserted between a predetermined pair of protrusions 310 and 320 so that the contact pin CP fitted in the cut groove 311 of the pair of protrusions 310 is fitted into the groove 211 provided in the protrusion pair 310 . Then, the pressing member 400 is locked to the base member 300 so as to press the terminal fitting 200. As a result, the contact pin CP of the female connector 100
and the terminal fitting 200 are directly connected without intervening lead wires, screw tips, screws, etc. as in the conventional case. Thereafter, the cable is inserted through the insertion port 310, each core wire is connected to the bent side 220 of the predetermined terminal fitting 200 as in the conventional case, and the cable is clamped to the clamp part 340, and then the cover 500 is attached.

With this configuration, the base member 3
The female connector 100 can be easily attached to the terminal fitting 2, and the contact pins CP of the female connector 100 and the terminal fitting 200 can be easily attached to the terminal fitting 2.
Connection can be easily made by simply inserting 00 into a predetermined position. In addition, this eliminates the need for the screw tip 4, lead wire 5, screw 7, etc. for connecting the contact pin CP and the terminal fitting 6 as in the past, reducing the number of parts. Since no work space is required, the device can be made smaller.

In the above embodiment, an example of a relay terminal board for relaying connection between a 20-core cable and a 4-core cable has been described, but the number is not limited to this, and the number may be increased or decreased as necessary.

Furthermore, the present invention is not limited to relay connection of indoor wiring for telephone lines, but is also effective for relay connection of various types of wiring.

(Effects of the Invention) As explained above, according to the present invention, it is possible to realize a relay terminal board that has a relatively small number of parts, can be easily assembled, and can be downsized.
