Description
CABLE JOINT APPARATUS
This invention relates to cable joint apparatus.
For the connection of cables along motorways and roads, difficulty occurs in connecting the cables such that the cables can be routed to a plurality of different places. More specifically, substantially every transmission circuit is different so that each joint requires a different combination of loading coils or buildout capacitors. In some cases, these are not required and a dummy board is fitted. This allows for extra transmission circuits to be added or removed later without disturbing longitudinal cable connections.
In order to reduce the above mentioned difficulty, we designed cable joint apparatus comprising a base, a frame which upstands from the base, a first printed circuit board which is supported by the frame and which extends in the direction of the frame, a second printed circuit board which is supported by the frame and which extends in the direction of the frame, a plurality of connectors mounted on the first printed circuit board, a plurality of loading coils mounted on the second printed circuit board, and connector means for electrically connecting the first and the second printed circuit boards, the connector means comprising ribbon cables. The cable joint apparatus was costly and complex to assemble. Also, because of the large number of connections, for example cable to connector and connector to connector, the operational reliability of the cable joint apparatus was not as good as was desired. It is an aim of the present invention to reduce these problems.
Accordingly, in one non-limiting embodiment of the present invention, there is provided cable joint apparatus comprising a base, a frame which upstands from the base, a first printed circuit board which is supported by the frame and which extends in the direction of the frame, a second printed circuit board which is supported by the frame and which extends in the direction of the frame, a plurality of connectors mounted on the first printed circuit board, a plurality of loading coils mounted on the second printed circuit board, and connector means for electrically connecting the first and the second printed circuit boards, the connector means comprising male and female plug-in connectors.
The use of the male and female plug-in connectors makes the cable joint apparatus of the present invention much easier to use than the above mentioned known cable joint apparatus, especially in holes in the ground where the cable joint apparatus is intended to be placed and where space is very restricted.
Preferably, the cable joint apparatus is one in which the male and female plug-in connectors have offset connector members for ensuring that the male and female connectors are the correct way around before they can be connected.
The cable joint apparatus may include capacitors mounted on the second printed circuit board.
Cable clips may be positioned between the connectors on the first printed circuit board.
The frame is preferably a metal strip frame.
The base will usually be provided with a plurality of cable ports. The base can be of any suitable and appropriate shape so that, for example, the base may be a circular base.
An embodiment of the invention will now be described solely by way of example and with reference to the accompanying drawings in which:
Figure 1 shows known cable joint apparatus; and
Figure 2 shows cable joint apparatus of the present invention.
Referring to Figure 1, there is shown cable joint apparatus 2 comprising a base 4, and a frame 6 which upstands from the base 4. A first printed circuit board 8 is supported by the frame 6 and it extends in the direction of the frame 6 as shown. A second printed circuit board 10 is also supported by the frame 6 and it also extends in the direction of the frame 6. As can be seen from Figure 1, the first and second printed circuit boards 8, 10 extend in the same general plane.
A plurality of connectors 12 are mounted on the first printed circuit board. As can be seen, there are six of the connectors 12. Each connector 12 is a lDC connector 12 and it extends longitudinally with respect to the frame 6 and the first printed circuit board 8.
A plurality of loading coils 14 are provided as shown on the second printed circuit board 10. The second printed circuit board 10 is also provided with a third printed circuit board 16 which acts as a capacitor board and which is located in guides 18, 20.
Connector means in the form of ribbon cables 22, 24 are provided as shown for electrically connecting the first and the second printed circuit boards 8, 10.
The cable joint apparatus 2 is such that it includes cable clips 26 positioned between the connectors 12 on the first printed circuit board 8.
The frame 6 is a metal strip frame as shown comprising a main strip 28 and a support strip 30. As shown, the main strip 28 is bent almost to the form of a rectangle. The main strip 28 and the support strip 20 are secured to the base 4 by bolts 32 as shown.
The base 4 is provided with a plurality of cable ports 34. There are seven of the cable ports 34 as can be seen from Figure 1. The base 4 is circular as shown and it has an upstanding side wall 36.
The cable joint apparatus 2 is designed to be placed in a hole, for example a circular hole in the ground alongside a road such as a motorway.
Referring now to Figure 2, there is shown cable joint apparatus 38 in which similar parts as in Figure 1 have been given the same reference numerals for ease of comparison and understanding.
In Figure 2, it will be seen that the ribbon cables 22, 24 of Figure 1 have been replaced by male and female plug-in connectors 40, 42. Either one of the male and female plug-in connectors 40, 42 can be the male connector with the other connector being the female connector. The use of the male and female plug-in connectors 40, 42 makes it much easier than using the ribbon cables 22, 24 to connect the first and the second printed circuit boards 8, 10 together.
It will. be seen from a comparison of Figures 1 and 2 that the cable joint apparatus 38 shown in
Figure 2 has capacitors 44 instead of the capacitor printed circuit board 16.
The cable joint apparatus shown in Figures 1 and 2 is not as costly to manufacture and assemble as our previous cable joint apparatus. Also, the cable joint apparatus shown in Figures 1 and 2 is able to operate with a good degree of reliability.
It is to be appreciated that the embodiment of the invention described above with reference to the accompanying drawings has been given by way of example only and that modifications may be effected. Thus, for example, the base 4 can be of different shapes to that shown.
