Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a connector-connected wire network.

When making electrical connections between the main parts of television receivers and other electrical equipment, wiring each wire one by one on the equipment's manufacturing line would take time, increase man-hours, and reduce the quality of the product. In order to avoid this, a separate connector connecting wire network is prepared for connecting these main components, and this can be used to quickly make electrical connections between the main components. A method has been adopted to do so. A conventional method of manufacturing this type of connector-connected wire network will be described with reference to FIG. 1 of the accompanying drawings.

FIG. 1 schematically shows, in a plan view, an example of a workbench according to a conventional method for manufacturing a connector-connected electric wire network. Reference numbers 1, 2, 3 and 4 indicate connectors that are respectively coupled to phase connectors provided on the main parts of the electrical equipment. These connectors 1, 2, 3, and 4 are installed on a workbench in a positional relationship that is approximately the same as the positional relationship between the mating connectors of the main parts of the electrical equipment. Reference numerals 5, 6, 7, 8 and 9 indicate wire locating pins placed upright in place on the workbench. Reference numbers 10A to 10J indicate electric wires wired between each connector. Reference numbers 11, 12, 13 and 14 indicate binding bands for binding electric wires. As examples of conventional manufacturing procedures for such a connector-connected wire circuit network, the following two methods have been common.

Procedure example () (i) Cut each of the electric wires 10A to 10J deemed necessary to a predetermined length. For example, electric wire 10A
To determine the length of the connector 2, hook it from the predetermined terminal position of the connector 3 installed on the workbench to the wiring positioning pins 7 and 6.
Lay the wires to be used on the workbench up to the predetermined terminal positions, and cut the wires at each terminal position.

(ii) Each end of the electric wires 10A to 10J thus cut to a predetermined length is subjected to an insulation stripping treatment so that it can be connected to a connector terminal.

(iii) Attach connector terminals to the stripped end of each wire by crimping, soldering, wrapping, etc.
I'm going to install one.

(iv) In the case of crimp connection, each connector terminal is housed in the predetermined terminal position of the corresponding connectors 1, 2, 3, and 4.

(v) Binding bands 11, 12, 13 as necessary
and 14 to bundle the electric wires 10A to 10J.

(vi) Conduct incorrect wiring inspection.

Procedure example () (i) Cut the electric wires 10A to 10J that are deemed necessary to a predetermined length in the same manner as in step (i) of procedure example ().

(ii) Lay these electric wires 10A to 10J on a workbench as shown in FIG.

(iii) Binding bands 11, 12, 13 as necessary
and 14 to bundle the electric wires 10A to 10J.

(iv) Insulation is stripped from the ends of the wires 10A to 10J so that they can be connected to connector terminals.

(v) Crimp each end of the wire thus treated to the corresponding terminal of connectors 1, 2, 3 and 4;
Connect the wires by soldering, wrapping, etc.

(vi) In case of crimp connection, each terminal shall be housed in the connector.

(vii) Conduct incorrect wiring inspection.

Most of the conventional manufacturing methods described above use crimping, soldering, and wrapping to connect each connector, and also measure, cut, and attach terminals to each wire one by one. It was a very complicated process that required time and man-hours.

SUMMARY OF THE INVENTION In view of these drawbacks of the prior art, it is an object of the present invention to provide a very simple method for manufacturing a connector-connected wire network.

Next, the present invention will be described with reference to an embodiment of the present invention based on FIG. 2 of the accompanying drawings.

FIG. 2 is a perspective view showing an example of a workbench in the middle of manufacturing a connector-connected wire network according to the manufacturing method of the present invention. Connector 21, 2
2, 23 and 24 are press-connection type connectors that are connected to the corresponding connectors of the main parts of the electrical equipment to which electrical connection is to be made using the connector connection wire network for this purpose. placed in place. In this case, the connectors 21, 22,
Arrangement opening 25 for insulation displacement terminals 23 and 24
It is preferable that A to 25J face upward. On this workbench, there are
Wire pitch determining pins 26, 27, 28, 29,
30, 31, 32 and 33 are provided,
Also, in the right place, there is a pin 3 for changing the direction of the electric wire.
4, 35, 36, 37, 38, 39, 40 and 41 are provided. Each wire pitch determining pin is connected to the connectors 21, 22, 23 and 2
They are arranged at intervals equal to the terminal arrangement pitch of 4. According to the manufacturing method of the present invention, the wires are stretched between the terminals of each connector in a desired pattern using wire pitch determining pins and direction changing pins, and then the wires are connected to each terminal by pressure welding. An example of this will be described in detail with reference to an illustrated example. First, one end of one electric wire 42 is wound around one of the right end pins of the direction change pins 35 and fixed. Then, the wire 42 is passed between the wire pitch determining pins 29, across the terminal arrangement opening 25F of the connector 22, and further passed between the wire pitch determining pins 28 and hooked onto the direction changing pin 36 to change direction. Next, the electric wire 42 is hooked onto the direction changing pin 37, turned toward the connector 21, passed between the electric wire pitch determining pins 26, and passed over the terminal arrangement opening 25B of the connector 21 to further determine the electric wire pitch. pass between the pins 27. Furthermore,
The electric wire 42 is hooked onto the direction changing pin 34 and turned again toward the connector 21, and is passed between the electric wire pitch determining pins 27 and between the electric wire pitch determining pins 26 and into the terminal arrangement opening 25A of the connector 21. passed on above. Furthermore, the electric wire 42 is
It is hooked on the direction changing pins 37 and 41 to change the direction toward the connector 23, and is connected between the wire pitch determining pin 30 and the wire pitch determining pin 3.
1 through the terminal array opening 25 of the connector 23.
Passed on G. Next, the wire 42 is returned to the connector 23 using the direction change pin 39, passed between the wire pitch determining pins 31 and between the wire pitch determining pins 30, and then passed through the connector 23.
It is passed over the terminal array opening 25H of No. 3. Furthermore,
The wire 42 is hooked onto the direction change pins 41 and 38 and directed toward the connector 24, and passed between the wire pitch determining pins 32 and between the wire pitch determining pins 33 onto the terminal arrangement opening 25J of the connector 24. be passed on to Next, the electric wire 42 is returned to the connector 24 using the direction change pin 40, and is passed between the electric wire pitch determining pins 33 and between the electric wire pitch determining pins 32 to the terminal arrangement opening 25I of the connector 24. passed on above. The wire 42 is then further directed toward the connector 22 using the redirection pins 37 and 36;
It is passed between the wire pitch determining pins 28 and between the wire pitch determining pins 29 and over the terminal array opening 25E of the connector 22. Next, the electric wire 42 is hooked onto the direction change pin 35 and returned to the connector 22 again, and passed between the electric wire pitch determining pins 29 and between the electric wire pitch determining pins 28 to arrange the terminals of the connector 22. It is passed over the opening 25D. Furthermore, the electric wire 42 is connected to the direction change pin 3
6 and 37 toward the connector 21, and pass between the wire pitch determining pins 26 and the wire pitch determining pins 27 to connect the connector 21.
is passed over the terminal array opening 25C, and finally,
It is wound around one pin at the right end of the direction change pins 34. In this state, the electric wires 42 are stretched in a predetermined pattern so as to pass over the terminal array openings of each connector in an aligned manner. Although the figure only shows as many terminal array openings as are necessary for explanation, each connector has two rows of similar terminal array openings arranged at the same pitch. The wiring of the electric wires onto the terminal arrangement openings can be easily carried out in the same manner as described above, using pins for determining the pitch of each electric wire and pins for changing direction. According to the manufacturing method of the present invention, after all the wiring on the terminal array opening of each connector is completed, appropriate insulation displacement connection between the insulation displacement type terminal accommodated in the terminal array opening of each connector and the electric wire is performed. This is done using a tool. After these insulation displacement connections, unnecessary portions of the wires are cut and removed. For example, in FIG. 2, the electric wire 42 may be cut at a position indicated by reference numeral 43. Thereafter, by removing the connectors 21, 22, 23, and 24 and the electric wires 42 press-connected thereto from the workbench, the desired connector-connected electric wire network has been created. On such a workbench, if a sequence number indicating the order of wiring is attached to each pin according to the wiring pattern of the desired electric wire network, wiring can be performed very easily and without error. convenient. Further, although the above embodiment describes wiring between four connectors, the present invention is not limited thereto.

As described above, in the manufacturing method of the present invention, the pressure welding type connector is arranged in a desired positional relationship, and the wires are stretched in a desired pattern using the wire pitch determining pin and the direction change pin, and the wires are then pressure connected. Since a desired connector-connecting wire network can be created by simply cutting and removing unnecessary wire portions after wiring, this method has many advantages over conventional methods, as follows.

(a) There is no need to measure and cut the length of each electric wire to be laid.

(b) It is possible to connect the terminals of each connector all at once.

(c) Since it is a pressure weld connection, there is no need for pre-treatment such as stripping the insulation of each wire.
