[Industrial application field]

The present invention relates to a distribution board for private branch exchange telephones installed in offices such as government offices, companies, factories, and banks, and more particularly to a jumper wiring method for a distribution board installed in a business office, which facilitates the wiring of jumper wires.

Measures to take when relocating subscribers or relocating extension telephones, opening lines, and adjusting traffic loads are handled by changing the wiring of jumper wires. It is required that the jumper wire installation work be easy.

Here, private branch exchange telephones include private branch exchanges, distribution boards, extension telephones, in-house cables, relay cables drawn from the telephone office, other power equipment and test equipment, etc., and interconnection of extension telephones and relay with the telephone office. A cable is used to connect an extension telephone and a regular telephone.

A distribution board is a facility for terminating relay cables, private branch cables, and private branch cables from private branch exchanges, and easily switching connections between them by wiring jumper wires.

[Conventional technology]

Figure 2 shows a wiring system diagram of a distribution board installed in a business office.

A private branch exchange telephone 50 in a business office includes a private branch exchange 51, terminal boards 52 to 55 mounted on a distribution board, and an extension telephone 56.
The terminal board (an example of mounted components) 52 and the telephone office 60 are connected by a relay cable 71, and the terminal board 5
3 and the private branch exchange (trunk circuit terminal) 51, and the terminal board 54 and the private branch exchange a (line circuit terminal) 51 are connected by internal cables 72 and 73, respectively, and the terminal board 55 and the extension telephone 56 are connected by the private cable 74. be done. Terminal board 52 and terminal board 53 and terminal board 54 and terminal board 5
5 are connected by jumper wires 75 and 76, respectively.

In the office-installed distribution panel, a relay cable termination side distribution panel (52,
53) and a local cable termination side distribution board (54, 55) that performs connection switching between the local cable 74 and the line circuit terminal of the private branch exchange 51 via the local cable 74 and the local cable 73 are formed in the same structure.

FIG. 3 is a diagram illustrating a conventional wiring method for jumper wires. The reference numbers shown in FIG. 3 correspond to those in FIG.

The terminal plates 52 to 55 are fixed in the vertical direction to supports (not shown) of the wiring board. Terminal boards 52 (yz) and 53 (y+) constituting the relay cable termination side distribution board (Y) terminate the relay cable 71 and the intra-office cable 72 on the left side of the front, respectively. Terminal boards 54 (x, ), 55 (xz) constituting the internal cable termination side distribution board (X) terminate the internal cable 73 and internal cable 74, respectively, on the left side of the front. Jumper wires 75 and 76 are connected to the front right side of each of the terminal boards 52 to 55 by passing them behind the pillars.

[Problem that the invention seeks to solve]

However, in such a conventional jumper wiring method, since the cables 71 to 74 and the jumper wires 75, 76 are not separated from each other in the installation area, the cables 71 to 74 may intrude into the jumper wires 75, 76 installation area. In the case where the jumper wires 75 and 76 are terminated, the path for routing the jumper wires 75 and 76 becomes narrow, making it difficult to wire the jumper wires.

Furthermore, when laying the jumper wires 75, 76, it was necessary to pass the wires behind the supports fixing the terminal boards 52 to 55, which worsened the workability of laying the jumper wires, such as intertwining of the jumper wires. In addition, jumper wire wiring work was performed on the sides of the terminal boards 52 to 55, resulting in poor working conditions.

The present invention solves these conventional problems,
To provide a jumper wiring method for a distribution board installed in an office, which facilitates jumper wire wiring work and allows simple wiring changes.

[Means for solving problems]

In order to achieve such an object, the present invention provides a relay cable termination side distribution board for terminating relay cables from a telephone office and intra-office cables of a private branch exchange to mounted components, and a relay cable termination-side distribution board for terminating relay cables from a telephone office and intra-office cables of a private branch exchange to mounted components, and In a jumper wiring method for an office-installed distribution board, which is comprised of an on-premises cable termination-side distribution panel that terminates the internal cable of an exchange to a mounted component, the relay cable termination-side distribution panel and an on-premises cable termination Each installed component of the side distribution board is connected to the left and right, respectively, to form a horizontal jumper line passage at the rear thereof, and a vertical jumper line passage is provided at each end of the relay cable termination side distribution frame and the premises cable termination side distribution frame. , and the jumper wires are wired using horizontal jumper wire passages and vertical jumper wire passages in each of the relay cable termination side distribution frame and the local cable termination side distribution frame.

[For production]

In the present invention, the front side of the mounted component is the jumper wire connection terminal surface,
Arrange so that the back side becomes the cable termination terminal surface, and secure a horizontal jumper wire passage between the mounted components and the support as a routing area for the jumper wires, Provide vertical jumper wire passages at each end of the distribution frame.

By separating the cable termination area and the jumper wire routing area in this manner, the jumper wire wiring work can be facilitated, and the jumper wire wiring route can be set regularly in a two-dimensional manner.

Terminal boards 11 and 12 of the relay cable termination side distribution board Y serve as the termination side yI of the intra-office cable 21 connected to the trunk circuit terminal of the private branch exchange and the termination side y2 of the relay cable 22 from the central office, respectively. , terminal boards 13 and 14 of the local cable termination side distribution board X serve as the termination side x1 of the local cable 23 and the termination side x2 of the local cable 24, respectively, which are connected to the line circuit terminals of the private branch exchange. The termination side y1 of the intra-office cable 21, the termination side y2 of the relay cable 22, the termination side X of the intra-office cable 23, and the termination side x2 of the intra-office cable 24 are connected by jumpers 'a25 and 26, respectively. In the embodiment of the present invention, a horizontal jumper wire passage 31 is formed between each terminal board 11 to 14 and the support, and a vertical jumper wire passage 33 is formed between the relay cable termination side distribution board Y and the premises cable termination side wiring iXO. The horizontal jumper wire passage 31 and the vertical jumper wire passage 33 are used to connect the jumper wires 25 and 26.
It is characterized by carrying out the installation work.

The relay cable 21, intra-office cables 22, 23, and local cable 24 are terminated on the back surfaces of the terminal boards 11-14.

The wiring routes of the jumper wires 25 and 26 are set using horizontal jumper wire passages 31 and vertical jumper wire passages 33 between the terminals indicated by black dots.

For example, terminal a of the terminal board 14, where the local cable 24 from the extension telephone is terminated, and terminal a2 of the terminal board 13, where the local cable 23 from the line circuit terminal of the private branch exchange is terminated, are connected to the jumper. When connected by the wire 26, the jumper wire 26 is accommodated in the lateral jumper wire passage 31. If there is no room to connect a jumper wire to a horizontal terminal board, the jumper wire is connected to the corresponding terminal on the upper or lower terminal board via the vertical jumper wire passage 33.

Therefore, by providing the horizontal jumper wire passage 31 and the vertical jumper wire passage 33, the wiring route of the jumper wires is organized, and the work of laying or changing the wiring can be easily performed.
