It is known from the paper. Such a known terminal board used as a connection terminal accommodating member has a drawback 7 in that a lightning arrester cannot be incorporated therein.

OBJECTS OF THE INVENTION An object of the present invention is to provide a terminal board of the type mentioned at the outset, which allows the installation of a lightning arrester and at the same time allows efficient wiring of the terminal board.

Structure of the Invention According to the present invention, the subject is: a terminal board of the type mentioned at the outset, which is separated by an intermediate wall in the longitudinal direction of the insulating material member at the top of the insulating material member and is open at the top; A predetermined number of accommodation chambers 7 are provided, a contact spring connected to the connection terminal is provided on the side wall of the accommodation chamber adjacent to the connection terminal, and a ground bus member is provided between the two contact springs provided oppositely. This problem is solved by making the part rush into the containment chamber.

Effects of the Invention The terminal board according to the present invention can be easily constructed, and the volume can be reduced if the insertion depth is small. The terminal board according to the invention is advantageous in that it can be used as a terminal receiving element itself and, at the same time, can additionally be equipped with a lightning arrester.

In the embodiment of the terminal board according to the present invention, when a 6-pole surge arrester is used, the intermediate connection terminal of the 6-pole surge arrester is held between the leg springs of the ground bus member provided in the plane of the ground bus member. There is.

Additionally, a two-pole lightning arrester or a six-pole lightning arrester 7 can be incorporated into the terminal board according to the invention.

In a further embodiment of the terminal board according to the invention, at least two projections are provided on the sides of the intermediate wall forming the respective receiving chamber, these projections being guided on one side of the terminal board and carrying the voice conductor. Used to guide the twin connection terminals provided on the other side of the terminal board.

Furthermore, in the terminal board according to the present invention, conductor guide slits (Y) are provided juxtaposed at least on the longitudinal edges of the upper and lower longitudinal surfaces of the side walls of the terminal board, and the conductor guide slits are provided vertically below the upper conductor guide slit, respectively. Guide slits are provided corresponding to the core wires, and a predetermined number of conductor guide ear holes are provided in parallel in the longitudinal direction on the lower surface of the terminal board, in which case each conductor guide ear hole is provided corresponding to a plurality of core wires. ing.

This makes it possible to easily pre-wire the incoming wires, in which case the special star cables (according to their respective color codes) are guided through the conductor guide holes provided on the underside of the terminal board and then into the individual cores. The wires can then be clamped separately to the terminal board using two mutually arranged conductor guide slots y. Therefore, it becomes possible to perform clear wiring where the wiring progress of the line can be seen at a glance.

In a further embodiment of the terminal board according to the invention, each corner of the terminal board is provided with a conductor guiding channel having openings on both sides of the side walls adjacent to the respective corner; The external forming surface is formed by two wedge-shaped projections connected to the terminal board, these wedge-shaped projections forming an introduction slit for the conductor running downwardly inclined. .

For example, with such a conductor guiding channel, the lateral guiding of the jumper wires to be connected is considerably simplified.

Description of examples The invention will now be explained in detail with reference to the illustrated embodiments.

The illustrated terminal board 1 has an insulating material part 2 which has, in its upper part, a receiving chamber 3 for accommodating a lightning arrester.

A number of twin terminals 4 are housed on the upper longitudinal side of the insulating material part 2, and are connected to contact springs 5 which project into the adjacent side walls of the receiving chamber 6. 1st
In the terminal board 1 shown in the figure, the contact spring 5 is
A six-pole lightning arrester 6 is provided between them.

In that case, the intermediate connection terminal of the 6-pole lightning arrester B is the ground bus member 7.
(see Figure 2).

The insulating material member 2 is assembled with an upper part 8 by a mounting lock.
and a lower part 9. Before assembling both the upper and lower parts, the corresponding ground bus member is inserted into the upper part 8 from below.The intermediate walls 1o of the storage chamber A are each provided with a groove in the middle in the lower part. . Further, since the bottom of the storage chamber 3 is provided with a slit in the center relative to the intermediate wall 10, the web of the ground bus member can be inserted into the storage chamber 3 through this slit.

Next, the ground lines 7 and 11 will be explained using FIGS. 5 and 6. Since it should be possible to incorporate the three-pole arrester 6 at the same time as the two-pole arrester 12 in the terminal board according to the invention, a different ground bus member is required. Both ground busbars are formed with substantially hollow metal strips which are curved at both ends to form ears for the mounting screws forming the ground contact. .

As shown in FIG. 5, the ground line 11 for the two-pole surge arrester 12 can be deformed so that the individual surge arresters in the accommodation chamber are contact-connected to the ground bus member on both sides. 6
Since the ground bus member 7 for the pole arrester 6 has two leg springs for each storage chamber, a reliable contact connection can be made between the intermediate connection terminal of the surge arrester and the ground bus member 7.

Also shown in FIGS. 5 and 6 is the connection between the twin connecting terminal 4 and the contact spring 5. In this case, the component with the respective contact spring 5 and twin connection terminal 4 can be constructed in two parts or, as shown in FIG. 6, can be constructed in one piece. Moreover, 16 shows another modification of the contact spring.

Figures 2 to 4 show the lightning arrester built into the terminal board, in which case a 6-pole lightning arrester 6 is shown built into the terminal board in the right half of each figure, and Figures 2 to 4 show the lightning arrester 6 built into the terminal board. In the left half of the figure, a two-pole lightning arrester 12 is shown assembled into a terminal board, and as can be seen from FIGS. They are staggered from each other. Since the two twin connection terminals provided for each storage chamber B are provided corresponding to one double center line, the conducting wire can be guided accurately. Furthermore, such a conductor guiding method is such that a protrusion 15 is provided on the intermediate wall 10, and between the protrusions 15, a conductor entering from one side of the terminal board is connected to a twin connecting terminal provided on the other side of the terminal board. By being able to guide you through the process, it becomes much easier.

Also, as shown in FIGS. 2 to 4, conductor receptacles are provided at the longitudinal edges of the upper and lower longitudinal surfaces of the insulating material member, in which case the upper and lower conductor receptacles are connected to one
One ear hole is provided for a predetermined number of conductor receivers provided together at the bottom of the terminal board, and the output wire and the human core wire are passed through the ear hole into the predetermined number of conductor receivers. I am trying to guide you.

Next, the present invention 1. The wiring of conductive wires will be explained below. Different terminal boards 16 are shown in FIGS. 7 to 10, in which case FIG. 7 shows a terminal board for distribution wiring as a separate wiring member, and FIGS. The figure shows a terminal board that is used as a connection terminal member and incorporates a lightning arrester. These two types of terminal boards commonly have connection terminals 17, which are used for connecting conductors, provided on the longitudinal side surface above the insulating material member. Conductor guide grooves 18 are provided in parallel on the longitudinal edge of the upper longitudinal surface of the terminal board 16.

It can be seen from FIGS. 8 and 10 that conductor guide slits are provided side by side on the lower longitudinal side of the terminal board 16. For example, as shown in FIG. 8, a conductor guide ear hole 20 is provided on the lower surface of the terminal board according to the present invention. In this case, the conductor guide ear hole 20 can be provided in the center of the lower surface for symmetry.

FIG. 10 shows the wiring for incoming lines from the outside. In this case, the four incoming core wires are grouped together and guided to the lower side of the distribution terminal/slave board 16 through the conductor guide ear holes 20, respectively.

As shown, each conductor is then inserted and clamped into two corresponding conductor guide slits. The individual core wires are colored in various colors to make them easy to distinguish, so they are easy to understand, and the wiring progress of the wire circuit can be seen at a glance. It is thus advantageous that incoming lines from the outside can be wired before the distribution terminal board 16 is finally fixed to the terminal board rack. After installing the distribution terminal board 16 on the rack, it is only necessary to contact and connect the individual core wires coming in from the outside to the connection terminals 17.

The connection pin of the incoming line 26 from the outside and the jumper line 24 can be connected. When wiring the jumper wires 24, the conductor guide slit provided at the longitudinal edge of the lower surface of the distribution terminal board can be omitted. The jumper wires connected to the connection terminals 17 are then guided through the upper conductor guiding slits and then bundled and guided laterally through the conductor guiding channels 21. The outgoing jumper wire can be inserted into the conductor guide channel 21 on the F streetcar through the introduction slit 22, in which case the jumper wire can be inserted into the conductor guide channel 21 through the introduction slit 22.
A suitable configuration of 2 ensures reliable guidance.

Of course, as mentioned above, there is no need to provide a lower conductor guide slit to guide the jumper wires, so the terminal board is configured symmetrically so that the incoming wires from the outside can be routed into the frame structure regardless of the configuration of the terminal board. According to the arrangement of terminal board 1 or 16,
It is advantageous to be able to guide from the front as well as from the rear.
