Description

[Detailed Description of the Invention] The present invention relates to a wiring guide on a panel surface of a data acquisition device, a sequence controller, etc.

In general, data acquisition devices, sequence controllers, and other computer-related equipment that handle a large number of input/output signal lines need to use efficient wiring methods to connect the input/output signal lines. In addition to the design considerations surrounding the connection terminals, it is also necessary to consider the connection to the terminals, the ease of inspection work, and the safety of wiring terminal processing.

Conventional solutions to this problem include making the terminal block made of resin and forming partition walls between each terminal to prevent contact with adjacent terminals, or creating holes for introducing lead wires at appropriate intervals on both sides. Molded a tunnel-shaped duct with a flexible resin, etc., cut it to the required length, fixed it near the terminal with screws, etc., and led the lead wire from the terminal inside the duct. Therefore, measures such as streamlining the wiring terminals are being adopted.

However, in any of the above cases, it could not be said that they were necessarily satisfactory in terms of price, free configuration suitable to the number of terminals, appearance suitable for mounting on the panel surface, etc.

Therefore, the present invention has been made to eliminate such drawbacks, and a corrugated barrier cut in an uneven manner is provided on a vertically steep side of a wiring guide made of an insulator formed into a cross-sectional shape. A notch is provided on the horizontal side of the wiring guide that touches the head of the wiring terminal, and the end of the lead wire screwed to the terminal is held by screws or the like so that it does not fall off easily. It is an object of the present invention to provide a wiring guide that leads to the valleys of the corrugated barrier portion and improves short-circuiting with adjacent parts and ease of wiring.

The present invention will be described below with reference to the illustrated embodiments.

In FIG. 1, reference numeral 1 denotes a wiring guide, and an appropriate number of wave-shaped barriers 2 are provided on the vertical sides of the wiring guide.

3 is a horizontal side of the wiring guide L-shaped molded product, and in order to contact the terminal terminal 4 of the lead wire from the side, a notch 5 with a semicircular opening is formed as shown in FIG.

The shaft portion of the terminal terminal 4 is provided with knurling 6 on its circumference, and has a rod-shaped terminal 7 at its tip.

Reference numeral 8 denotes an insulating bushing which brings the notch 5 of the L-shaped horizontal portion 3 of the wiring guide into contact with the terminal terminal 4 from the side.

The insulating bushing 8 and the metal duct 10, which are provided with a pinching edge 9 of the insulating bushing 8 at the lower end of the inner diameter, prevent the terminal terminal 4 from rotating by pushing the pinching edge 9 outward with the knurling 6. and fixing.

11 is a printed circuit board, 12 is a front metal panel, 13
14 is a solder that electrically connects the printed circuit board, and 14 is a set screw for the wiring guide.

In the present invention having such a configuration, when installing a wiring guide as shown in FIGS. The metal panel 12 is brought into contact with the notch 5 of the guide 1 from the side and fixed with the screw 14.
are sandwiched between the wiring guide 1 and the metal duct 10 and are attached in close contact with each other.

Therefore, according to the present invention, in the case of a device in which connection terminals are screwed to terminals and a large number of wires are connected, the wiring eyes can be sunk into the recesses of the corrugated barrier and the wires can be processed. Even if the end of the lead wire bends and tries to contact the metal panel, the upper surface of the metal panel is covered by the wiring guide horizontal part made of an insulating plate. Since it is covered, there will be no short circuit.

Further, line processing as a wiring force aid is facilitated, and assembly and manufacturing costs are also simple and inexpensive.

Further, when a pair of the wiring guide and the guide of the present invention are disposed opposite to each other with an interval on the vertical sides, the space within the interval becomes a wiring duct, which is convenient for wiring processing.
