DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector partition plate for facilitating the work of connecting and disconnecting a connector to or from a wiring board on which a number of connectors to which optical fibers or optical cords are connected are arranged vertically and horizontally. .

[0002]

2. Description of the Related Art In forming an optical fiber wiring network, a wiring board in which a number of connectors are arranged vertically and horizontally is used to switch a wiring system. FIG. 3 is a view showing an example of a wiring board, in which 11 is a wiring board, and 12 is a connector fixed to the wiring board. Normally, a wiring board is a flat one that stands upright with respect to the ground, making connections between the wiring arranged on the back side of the wiring board and the wiring arranged on the front side of the wiring board. In order to change the combination of the connection between the wiring on the back side and the wiring on the front side in accordance with the switching connection.

[0003] The connector has a size of about 10 to 15 mm in length and width, and 4 to 16 connectors are arranged vertically at a pitch of about 15 to 20 mm to form a row. 20 to 50 rows are arranged at a pitch of 25 to 30 mm to form a step, and several such steps are arranged vertically.

[0004] Connection with a wiring board is usually performed by inserting and removing a connector. On the back side of the wiring board, one connector that has completed the connection of the optical fiber or the optical cord is fixed so that the tip protrudes partially to the surface of the wiring board, and the optical fiber or the optical cord is inserted from the front side of the wiring board. An adapter is arranged and fixed on the wiring board, and a connector to which an optical fiber or optical cord is connected from the front side and the back side of the adapter is connected and connected. There is something to do.

[0005] Also, a large number of wiring modules having a row of adapters or connectors arranged on the back side of the frame are arranged side by side,
There is a case where the adapter or the connector is protruded to the surface side to form a wiring board. In any case, the operation is almost the same in that the connector to which the optical fiber or the optical cord is connected is inserted and removed on the surface side of the wiring board.

[0006] The connection switching work on the wiring board is performed while confirming the wiring number with the other party, but a person on the front side of the wiring board disconnects the connector at the point X, inserts it into the point Y, connects and connects. In many cases, the connector of Z is unplugged and inserted into the location X for connection. Here, the point X is when the connector connected to the point X is disconnected,
This is relevant when a connection connector brought from another location Z is inserted into the location X and reconnected, so the location of the location X must be searched twice.

[0007] Further, there is a case where another work is performed during the connection switching work. In such a case, the same place X is searched a plurality of times. The trouble of searching for the same place many times is not a big deal only once, but hundreds to thousands of connectors or adapters are arranged on one wiring board, and switching of wiring is from one to the next It is necessary to perform the same operation, so that the trouble of searching for the same place is increased, and the work time is increased.

As shown in FIG. 4, a connector 12 is connected to the surface of the wiring board 11 upright with respect to the wiring board 11, and an optical fiber or an optical cord 13 is connected to the connector 12. I have. Therefore, as shown in FIG. 4, the connector 12 is in a horizontal state, and the optical fiber or the optical cord 13 connected to the connector 12 also extends horizontally from the connector 12.

As the optical fiber, a fiber in which a glass fiber is coated with a UV-curable resin or the like, and a plastic coating for reinforcement is provided on the outside of the glass fiber in one or more layers is generally used. Further, as the optical cord, a glass fiber coated with a UV-curable resin or the like, a polyamide fiber or the like is added as a reinforcing material, and a plastic coating such as a vinyl chloride resin is applied to the outside is used.

[0010] In addition, when a multi-core connector can be connected at a time, a plurality of glass cords, each of which is coated with an ultraviolet curing resin or the like as an optical cord, are arranged in parallel and coated collectively. A resin coated with a plastic fiber such as a vinyl chloride resin with a polyamide fiber or the like added thereto may be used.

The optical fiber or the optical cord generally has an outer diameter of about 1 to 5 mm, has a certain degree of flexibility, and is bent if it has a radius of curvature of a predetermined value of about 30 mm or more. As shown in FIG. 4, it can be bent downward at a radius of curvature where it exits horizontally from the connector, and can be led downward to pass through the space between the floor and the wiring board to another device. ing.

Since the optical fiber or the optical cord is connected to the connector as described above, when inserting or removing the connector at a certain location, the optical fiber or the optical cord connected to the adjacent connector is pushed away to remove the gap. You have to make and work. However, if the adjacent optical fiber or optical cord is subjected to excessive bending, the transmission characteristics will change, which will hinder the line in operation.
Care must be taken not to give excessive bends to adjacent optical fibers or optical cords.

The optical fiber or the optical cord connected to the connector is not so much bent by pushing the optical fiber or the optical cord away from the connector, but the optical fiber or the optical cord is hardly bent near the connector. Since the optical fiber or the optical cord is connected to the connector and cannot move freely, pushing the optical fiber or the optical cord may give an excessive bending.

On the other hand, when the mounting density of the connector on the wiring board is increased, when inserting and removing the connector by hand, a portion close to the optical fiber or optical cord connector connected to the adjacent connector is pushed away. As a result, the pushing out with the fingers is inevitably irregular, and it is difficult to prevent the optical fiber or the optical cord connected to the adjacent connector from being excessively bent.

[0015]

In the operation of inserting / removing a connector in connection with switching of a line on a wiring board, usually in one connection switching operation, a position of a target connector is searched a plurality of times in accordance with a wiring number. There is a need to.
Also, in the operation of inserting and removing the connector, care must be taken so that the optical fiber or the optical cord connected to the adjacent connector is not unreasonably bent. The present invention is to provide a working jig that eliminates such troublesome work and does not give excessive bending to an adjacent optical fiber or optical cord without paying much attention.

[0016]

SUMMARY OF THE INVENTION The present invention relates to a connector partition plate used for a wiring board for connecting and connecting a large number of connectors to which optical fibers or optical cords are connected vertically and horizontally.
It has a window surrounding one or a plurality of connectors as a group. The window frame has a wiring board mounting portion detachable from the wiring board and two sides connected to both side edges of the wiring board mounting portion and away from the wiring board. And a wrapper portion made of a material having bending elasticity, which gradually widens and opens in a direction.

If this connector partition plate is attached to a desired group of connectors, it can be separated from other connectors, so that it is not necessary to search for the same location many times, and the optical fiber connected to the adjacent connector can be removed. Alternatively, the connector can be switched without paying much attention to the optical cord.

Further, since the wiring board is mainly made of steel or iron, the work can be more easily performed by attaching and detaching to and from the wiring board by using a magnet fixed to the mounting portion of the wiring board.

[0019]

FIG. 1 is a view showing an embodiment of a connector partition plate of the present invention. FIG. 1 (A) is a perspective view thereof, and FIG. 1 (B) is a plan view and a front view thereof. Show. Reference numeral 1 denotes a connector partition plate, which includes a wrapper portion 1a and a wiring board mounting portion 1b.

The wiring board mounting portion 1b is provided with a window 1c that can surround one or more connectors on the wiring board. The window frame of the window 1c does not need to be completely connected. For example, the bottom portion may be missing. Further, the number of adapters or connectors enclosed by one window can be arbitrarily determined from one to a dozen or so, but in the case of the wiring board of FIG. desirable.

The work of attaching the window frame of the wiring board mounting portion 1b to the wiring board must be as simple as possible. For this purpose, there is a method in which a small hole is formed in the wiring board 1 and a small projection is provided in the window frame portion of the wiring board mounting portion 1b and hooked. However, since the wiring board is mainly made of steel or iron, a permanent magnet is used. A small piece is fixed to the wiring board side (the side without the wrapper) of the window frame portion of the wiring mounting portion 1b,
It is preferable to attach to the wiring board with the permanent magnet because it is easy to attach and detach.

The wrapper part 1a includes a wiring board mounting part 1b.
It gradually expands in two directions, that is, right and left, as it goes away from it, and is made of a material having a bending elasticity that can expand the degree of opening by inserting a finger between the two.

FIG. 2 is a perspective view showing an example in which the connector partition plate of the present invention is attached to a wiring board. Reference numeral 1 denotes a connector partition plate, 1a includes a wrapper portion and a wiring board mounting portion 1b, and the wiring board mounting portion has a window 1c surrounding one or a plurality of connectors. Reference numeral 3 denotes a connector to which an optical fiber or an optical cord 4 is connected. FIG. 2 shows that the connectors in the center row are separated from the connectors in the left and right rows.

In the case of a detachable work partition surrounding eight adapters or connectors, both the wiring board mounting portion and the wrapper portion are provided.
It is made of a metal plate of stainless steel or the like having a thickness of about 0.5 mm or a plastic plate of polyester or the like having a thickness of about 0.5 to 1 mm. Is about 130 mm, C is about 20 mm, and D is about 30 mm. If the thickness of the stainless steel is also about 0.5 mm, the opening can be sufficiently enlarged only by pushing away the opening of the horn by hand.

Next, a method for performing the operation using the connector partition plate of the present invention will be described. First, when inserting or removing a connector to which an optical fiber or an optical connector is connected at a predetermined adapter or connector location, the number of the connector is counted according to the wiring number, and a desired location is searched for. The connector partition plate of the present invention is attached to a position of a wiring board including a group of connectors including the following.

When a fixing portion using a permanent magnet is provided on the wiring board mounting portion, the mounting can be easily performed simply by pressing the connector partition plate against the wiring board. Once the connector partition plate is installed, even when searching for the position multiple times, there is no need to count and search the connector position, just search for the required connector in a group and switch the connection. Work can be done quickly.

Further, when the connector partition plate of the present invention is used, since the wrapper portion is not very open at the time of mounting, the mounting can be performed without pushing away the optical fiber or the optical cord connected to the adjacent connector. In inserting and removing the connector, fingers are inserted into the opening of the trumpet section with the nectar sandwiched between fingers. At this time, since the wrapper is made of a material having bending elasticity, it can be spread by a finger, but since the outer surface of the wrapper is tapered, the optical fiber or optical cord connected to the adjacent connector is tapered. You will be pushed away along the surface.

In this case, since the optical fiber or the optical cord is uniformly pushed away by the tapered surface, the bending force applied to the optical fiber or the optical cord is uniformly distributed and cannot be applied to a specific portion of the optical fiber or the optical cord. No bending is added. Therefore, unlike the case where the optical fiber or the optical cord connected to the adjacent connector is pushed away with the finger, no trouble occurs due to the fluctuation of the transmission characteristics of the optical fiber or the optical cord connected to the adjacent connector.

[0029]

According to the connector partition plate of the present invention, one to a dozen or so groups including the desired connector to be switched on the wiring board can be separated from other connectors and can be detached. By simply searching, the second and subsequent times can easily find the desired position of the connector as long as the connector partition plate is not removed. Therefore, it is suitable for a switching operation in which it is necessary to search for a connector at the same position a plurality of times, such as a wiring board switching operation, and brings about an effect of reducing the operation time.

Further, the connector partition plate of the present invention has a wrapper portion, and the opening of the wrapper portion can be enlarged by a finger. However, since the optical fiber or optical cord connected to the adjacent connector is uniformly pushed away by the back surface of the wrapper part, the optical fiber or optical cord is subjected to unreasonable bending such as the case where a finger directly shakes the optical fiber or optical cord. Will not be given to Therefore, in the connection switching operation, there is no possibility that the transmission characteristics of the adjacent line are affected.
