Description

[Detailed Description of the Invention] The present invention relates to a terminal board that can separate and switch between a plurality of terminals using jumper connections on one terminal board.

For example, in a terminal board for communication equipment that separates and switches multiple external lines into multiple internal lines by jumper connection, there is a terminal board for external line connection equipped with multiple external line terminals and a plug terminal, and a terminal board for connecting external lines that has multiple external line terminals and plug terminals. Two terminal boards, one for connecting internal lines and the other equipped with terminals, are used, and jumper connections are made between these two terminal boards using jumper wires to separate and switch between external lines and internal lines. ing. In such conventional terminal boards, the separation and switching connections between each external line terminal and each internal line terminal are performed simply by changing the connection of each jumper wire arranged between the two terminal boards. Since two separate terminal boards are required, one for connecting external lines and the other for connecting internal lines, the cost is high, and the distance between each terminal board is high because jumper connections are made between each terminal board. Since it is necessary to increase the size of the terminal board, there is a disadvantage that the box for housing these terminal boards becomes large. Furthermore, the jumper wires placed between the two terminal boards intersect with each other, making the jumper work more complicated, and since each terminal board is separated, the number of man-hours required to assemble the terminal board increases. There was a drawback.

This idea was made in view of the above circumstances.
The purpose of this is to eliminate the above-mentioned drawbacks of the conventional method by molding the terminal board for external lines and the terminal board for internal lines into one unit, thereby miniaturizing the terminal board as one terminal board, and allowing wiring to be carried out in an orderly manner. To provide a terminal board which facilitates separation and switching work between external lines and internal lines and reduces costs.

The terminal board according to the present invention has a plurality of external line terminals (or each internal line terminal) connected to each jumper terminal on one side via each plug terminal, and a plurality of internal line terminals (or each internal line terminal) connected to each jumper terminal on the other side, respectively. or each external line terminal), and each of the plug terminals, each jumper terminal, each external line terminal, and each internal line terminal is integrally molded with an insulating material so as to be exposed to the outside.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a plan view of a 10-pair switching terminal board showing an embodiment of the present invention, Fig. 2 is a front view of Fig. 1, Fig. 3 is a side view of Fig. 1, and Fig. 4 is Figure 1A
-A' sectional view, FIG. 5 is a sectional view taken along line B-B' in FIG. 1, and FIG.

In FIGS. 1 to 6, the same parts are designated by the same reference numerals and explained. In FIGS. 1 to 6, a plurality of external line terminals 1 (only one is given a reference numeral and the same applies hereafter) are connected to one (outside line side) jumper terminal 3 or 3' via each plug terminal 2, 2'. It is designed to be connected to. In this case, as shown in FIGS. 4 and 5, each external line terminal 1 is connected integrally with each plug terminal 2', and each plug terminal 2 and 2' is electrically connected by inserting each separating ring 4. It is designed to be connected to Further, the plurality of extension terminals 5 are arranged approximately symmetrically with respect to the respective extension terminals 1, and as shown in FIGS.
As shown in the figure, each extension terminal 5 is integrally connected to the other (extension side) jumper terminal 6 or 6'. In this embodiment, 1 is described as each external line terminal and 5 as each internal line terminal, but each external line terminal 1 may be replaced with each internal line terminal, and each internal line terminal 5 may be replaced with each external line terminal, respectively. Of course.

Each of the above-mentioned external line terminals 1, each plug terminal 2, 2',
The jumper terminals 3, 3', 6, 6' and the extension terminals 5 are integrally molded with an insulating material and mounted on a common insulating base 7 so that each terminal is exposed to the outside. Note that 8 is a jumper ring and 9 is a jumper wire.

Since the present invention is constructed as described above, when connecting a plurality of outside lines to each extension line, such as in a telephone exchange, first connect each outside line to each outside line terminal 1, and then connect each extension line to each extension line. Connect to each extension terminal 5. Next, each cutting ring 4 is inserted into each plug terminal to connect each plug terminal 2 and 2', and one jumper terminal 3, 3' is connected to the other jumper terminal using each jumper wire 9 and jumper ring 8. By appropriately connecting the jumper terminals 6, 6' as shown in FIG. 6, it is possible to easily separate and switch between each external line and each internal line.

Next, referring to another embodiment of the present invention, it is possible to provide a terminal board that does not require a cutting mechanism, that is, a cutting ring. In this case, if the plug terminals 2, 2' are not provided, it is possible to obtain a terminal board having only a jumper connection between the terminals.

As described above, according to the present invention, the terminal board for external wires and the terminal board for internal wires are integrally molded to form one terminal board, thereby reducing the overall structure and making it possible to arrange each wiring in an orderly manner. This makes it possible to easily separate and switch between external lines and internal lines, and to reduce costs.
