Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting device for connecting the core wires of two communication multi-pair cables, and more specifically, the present invention relates to a connecting device for connecting the core wires of two multi-pair cables for communication, and more specifically, the present invention relates to a connecting device for connecting the core wires of two multi-pair cables for communication, and more specifically, the core wires of each of the two multi-pair cables are terminated. The present invention relates to a connection device for electrically connecting terminals of one multi-terminal block and terminals of the other multi-terminal block of a pair of multi-terminal blocks.

This type of device includes a pair of multi-terminal blocks, and randomly connects the core wires at one end of each of two multi-pair cables to the terminals of each of the pair of multi-terminal blocks without considering the core numbers. By transmitting a signal to identify the core number from each other end of the two multi-pair cables, each terminal of each multi-terminal block is associated with the core number, and the core number is determined. It connects the same terminals to each other.

As connection devices for connecting terminals of a pair of multi-terminal blocks, firstly, there are connection devices for wiring electric wires between corresponding terminals of the pair of multi-terminal blocks, and secondly, there are connection devices that connect terminals of a pair of multi-terminal blocks. There is a connection device that uses a crossbar switch, which has contacts arranged in a crossbar switch and closes the contacts using an electromagnetic relay.

However, in the first connection device, since the spacing between corresponding terminals varies, a large number of wires are cut to appropriate lengths and terminated by crossing each other. Wiring between all the terminals of the terminal block required a great deal of time, resulting in poor workability.

In addition, the second connection device has the problem that it is difficult to miniaturize a switch that accommodates a large number of contacts, and that a large amount of holding power or a complicated holding mechanism is required to maintain the conductive state of the contacts. The present invention was made in view of the above, and its purpose is to connect concave metal fittings to the intersections of covered wires that are wired in a grid pattern to a pair of multi-terminal blocks in advance. To provide a connection device which solves the above-mentioned problems by making the terminals of a pair of multi-terminal blocks conductive by driving the terminals into electrical connection through the concave metal fittings.

Examples of the present invention will be described below. FIG. 1 schematically shows a connection device 1 according to an embodiment of the present invention, and in the same figure, 2.3 indicates a pair of multi-terminal blocks arranged adjacent to each other in the X-axis direction and the Y-axis direction. The cores of a multi-pair cable (not shown) to which corresponding cores among a plurality of cores are to be interconnected are arranged with random core numbers. be cut off. The cable numbers are 1, 2°3, . . . up to 100. 4 is an insulating square plate with a pair of multi-terminal blocks 2 and 3 installed on adjacent sides. 5 is a multi-terminal block 3 with one end
6 is a covered wire in the X-axis direction terminated at -θj)1 is a covered wire in the Y-axis direction terminated at the other multi-terminal block 2, and these covered wires 5゜6 are arranged in a grid pattern. (the number of terminals of each multi-terminal block 2.3, that is, the number of core wires of the multi-pair cable) is wired. 7 is covered wire 5.6
This is a recessed metal fitting that is driven into the intersection of the square plate 4 and connects the covered electric wires 5 and 6 at the intersection to each other and is embedded in the square plate 4. 8 is on the square plate 4 in the Y-axis direction 1i
The horizontal bar 9 that moves in iJ is a driving part that moves in the X-axis direction on the horizontal bar 8 and drives the concave metal fitting 7 at the intersection of the covered electric wires 5.6.

FIG. 2 is a block diagram that does not show the moving mechanism for moving the driving part 9 and the horizontal bar 8 in the X-axis and Y-axis directions, and this moving mechanism is composed of a microcomputer built in the connecting device 1. A control device 10, a servo motor II rotated by an output signal from the control device 10, and a servo motor 1
The rotation of 1 is converted into movement in the X-axis and Y-axis directions, and the driving part 9,
It is equipped with a gear-rack-pinion mechanism 12 that moves the horizontal bar 8 in the X-axis and Y-axis directions, and the position signal detected by the position detection sensor 13 controls the amount of movement in the X-axis and Y-axis directions. By being fed to the device 10, the current flowing through the servo motor 11 is changed and adjusted to maintain the stability of the system.

FIG. 3 is a block diagram showing a hydraulic servo mechanism 14 that moves the recessed metal fitting 7 in the X-axis direction, and a servo valve 15 that converts a current signal from a control device 10 built into the connecting device 1 into an oil flow signal. , is equipped with a cylinder 16 that is driven by hydraulic pressure from the oil flow from the servo valve 15 and moves the recessed metal fitting 7 in the X-axis direction. This is done by being fed banked to the control device 10.

Next, a method of connecting the terminals of the multi-terminal block 2 and the terminals of the multi-terminal block 3 connected to the connection device 1 described above will be explained. First, the core wires of each multi-pair cable are randomly terminated to each terminal of the multi-end block 2.3 without considering the core number, and then the core wires are terminated from the other end of each multi-pair cable. The spatial position of the terminal corresponding to the core number in one multi-terminal block 2 (indicated by the X-axis coordinate) and the other multi-terminal block 3 are transmitted.
the spatial position of a similar terminal in (denoted by the Y-axis coordinate)
1# information is given to the control device 10. As a result, the terminal corresponding to the same core number of the two multi-pair cables is selected in the multi-terminal block 2.3, and the moving mechanism shown in FIG. moves in the X-axis and Y-axis directions, and determines the X-axis and Y-axis spatial position of the selected terminal on the multi-terminal blocks 2 and 3, that is, the specific position of the covered wires 5 and 6 terminated to each terminal. Stop at an intersection. For example, in the case of core number 1, it stops at the intersection of the 71st wire 51 of the covered wires 5 and the wire 61 of the covered wires 6. Then, by the signal output from the control device 10,
The driving part 9 drives the concave metal fitting 7 into the intersection, and the covered wires 5 and 6 at the intersection are electrically connected to each other.

FIG. 4 shows the driving part 9 in detail. Inside the driving part 9, a hydraulic device 14 and a hydraulic hose 17 are installed.
, a driving arm 18, a conductive wire 19, and the same number of recessed metal fittings 7 as the terminals to be connected.

Therefore, after the driving part 9 and the horizontal bar 8 come to the predetermined positions on the X and Y axes, the driving arm 18
descends in the Z-axis direction, grips one concave metal fitting 7, drives this concave metal fitting 7 into the intersection of the covered electric wires 5 and 6 on the square plate 4, fixes it, then ascends in the Z-axis direction, and returns to the original position. Return to position to complete.

The above operations are performed for each selected intersection of the covered wires 5 and 6, and connections are made between all terminals of the multi-terminal block 2 and all terminals of the multi-terminal block 3, and the two multi-pairs are connected. Corresponding core wires of the cable are interconnected by a connecting device 1.

In this case, a control device W10 consisting of a microcomputer is installed in the connecting device 1, and the movement of the driving part 9 and the horizontal bar 8 in the X-axis and Y-axis directions is controlled by electric servo control, and the driving of the recessed metal fitting 7 is controlled. Since it is based on electro-hydraulic servo control, all terminals can be connected in a short period of time.

FIG. 5 shows a state in which a recessed metal fitting 7 is driven into the intersection of the covered electric wires 5 and 6, and FIG. 6 shows a cross section taken along the recessed metal fitting 7 at the intersection of the covered electric wires 5 and 6. The recessed metal fitting 7 crushes and cuts the insulation coating of the covered electric wire 5.6 and presses it against the internal conductor, thereby connecting the inner conductor of the covered electric wire 5.6 via the recessed metal fitting 7, that is, a pair of multi-terminals. The terminals of blocks 2 and 3 to be connected to each other are electrically connected. Since the recessed metal fitting 7 is embedded in the square plate 4, the electrical connection between the two terminals is maintained unless it is removed from the square plate 4. Further, in this case, since it is easy to downsize the concave metal fitting 7, it is easy to downsize the square plate 4, that is, the connecting device Wi.

As described above, according to the connecting device of the present invention, the intersections of the covered wires wired in an orthogonal grid pattern from a pair of multi-terminal blocks are connected by the recessed metal fittings, and the connection is maintained. Problems with equipment that wires wires between terminals, or cross bar switch 7
Problems in devices that use the chip can be solved.
