Description

[Detailed Description of the Invention] The present invention provides a plurality of relay connection terminals or connectors for coaxial cables, etc., which are installed in a communication equipment rack and which relay connect an in-rack coaxial cord or cable and an in-office coaxial cable or cord. Regarding individually fixed terminal blocks.

Conventionally, this type of terminal block has a plurality of coaxial cable relay connection terminals or connectors 8 (hereinafter simply referred to as terminals) arranged and fixed on a substantially rectangular terminal block 2, as shown in FIGS. 1 and 2, and is used for communication. It is disposed in a terminal block accommodating portion 4 provided in the upper space of the equipment rack device 1 or the like. The input and output coaxial cords or cables 9 (hereinafter simply referred to as intra-rack coaxial cables) of the functional block (communication equipment) 7 mounted inside the rack are soldered and connected to the terminals 8 on the back side of the terminal block 2. There is. In addition, the intra-office coaxial cable or cord 3 (hereinafter simply referred to as the intra-office coaxial cable) is introduced from the rear space of the terminal block 2 to the front of the terminal block 2 through the upper part of the terminal block 2 and the spaces on both left and right sides. , it is possible to connect to the terminal 8 protruding from the front surface of the terminal block 2 by soldering or a connector.

In recent years, with the miniaturization of electronic components, communication equipment and rack equipment have become smaller and more densely packaged, resulting in an increase in the number of systems housed in rack equipment and an increase in the number of coaxial cables inside the rack. Moreover, the space for the terminal block accommodating portion is small. The conventional terminal block disposed in such a small space accommodating section has a small vertical and horizontal space, and it has become difficult to secure space for introducing the intra-office coaxial cable 3. Therefore, when multiple terminal blocks 2 are arranged, the space on either the left or right side of the terminal block 2 is saved, and the in-office coaxial cable 3 is routed through only one side to the front of the terminal block 2. This has resulted in the disadvantage that the bending radius of the coaxial cable 3 is restricted. This also limits the number of terminals, which hinders the achievement of high-density packaging.

The purpose of the present invention is to solve the above-mentioned conventional drawbacks,
To provide a terminal block capable of accommodating more terminals in a narrow space.

The present invention is attached to the surface of a terminal block accommodating part installed in a communication equipment rack, and has a plurality of terminals passing through the front and back sides.A first cable is connected to each terminal on the front side, and each cable is connected to each terminal on the back side. In a relay terminal block having a structure in which a second cable is connected to the terminal, it has the shape of a frame with a window opening in the center, the terminals are arranged and fixed through the frame, and the first cable is It is characterized by a structure in which it passes through the window and is connected to the front side of the terminal.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 3 is a perspective view showing an embodiment of the present invention. That is, it has a structure in which a plurality of terminals 8 are arranged and fixed to a frame 5 shaped like a picture frame. As shown in the figure, the intra-rack coaxial cable 9 connects to the terminal 8 on the rear side of the terminal block.
is soldered to. The in-office coaxial cable 3 is introduced forward from the space behind the terminal block through the window 6 surrounded by the frame 5, and is connected to the terminal 8 at the front of the terminal block.
It can be connected to by soldering or connector.

FIG. 4 is a perspective view showing a state in which the terminal block of this embodiment is mounted on the communication equipment rack 1. As shown in FIG. The input and output intra-rack coaxial cables 9 of the communication equipment 7 are soldered directly to the terminals 8 on the rear side of the terminal block. The intra-office coaxial cable 3 is introduced into the terminal block accommodating section 4 from above, introduced from the rear of the terminal block through the window section 6 to the front surface, and connected to the terminal 8 at the front surface of the terminal block. Since there is no need to provide a space on both the left and right sides of the terminal block, the size of the terminal block, that is, the size of the frame-shaped frame 5 can be set to the full size of the terminal block accommodating portion 4. Therefore, it is possible to mount a large number of terminals 8, and the size of the window 6 also becomes large. Therefore, the bending radius of the intra-office cable 3 can be increased, and the transmission quality is also improved. It goes without saying that the terminals 8 arranged in the frame 5 may be arranged in multiple rows. The terminal block shown in FIG. 4 has terminals 8 arranged in two rows on a frame 5.

As described above, in the present invention, the terminal block is formed into a frame shape, and the terminals are arranged and fixed to the frame, so that the size of the terminal block can be made to fill the storage space of the terminal block housing part. This has the effect of allowing many terminals to be mounted in a small space. Furthermore, it is possible to increase the bending radius of in-station coaxial cables, etc., and the transmission quality is also improved. Also,
Since the terminals are arranged around the outer periphery, the terminals can be spaced widely apart, interference between the terminals is small, and construction work is easy. It goes without saying that the present invention can also be applied to other cables than coaxial cables, such as optical fiber cables and pair cables.
