Description

[Detailed Description of the Invention] The present invention relates to a jig for wiring cables inside an electronic device, and more particularly to a jig for wiring cables for the front connector of a printed circuit board, which enables pre-wiring when the unit is not mounted. .

2. Description of the Related Art Generally, in printed boards of electronic devices such as computer systems that use a large number of digital integrated circuits, backboards are used to conduct wiring between the printed boards.

Furthermore, due to the lack of external connection terminals when interconnecting only with the bank board, a front terminal for cable connection is provided on the opposite side (front side) from the connection with the bank board.
A method is used in which connectors are attached and cables are wired between printed boards.

Generally, for assembly and cable wiring, a printed board is mounted on a shelf with a backboard attached, and the completed unit is stored in a suspended structure called a gate, and the front connectors installed on the front surface of the Nami-tani printed board are connected to each other. cable wiring.

According to this method, cable wiring cannot be performed until the bank board, shelf, and printed circuit board are completed and mounted on the gate as a unit, which lengthens the inventory period for the printed circuit board backboard and other items. The problem was that it required a turn to wait for the process.

An object of the present invention is to provide a wiring jig that enables cable wiring to be connected to a button on the front surface of a printed board without requiring a printed board, a bank board, or the like.

According to the present invention, a backboard on which a printed board is mounted;
Wiring for fixing the front connector for cable wiring in the same position as when the unit is mounted, by mounting a plurality of units consisting of a printed board having a front connector for cable wiring in the opposite direction to the backboard connected to the gate. A wiring jig is obtained in which a panel is provided and the wiring panel is mounted and cables are wired when the unit is not mounted.

A detailed explanation will be given below according to the drawings.

FIG. 1 is an explanatory diagram showing a method of mounting a printed board on a shelf.

A backboard 1 is attached to the shelf 2, which includes wiring for interconnecting printed boards, wiring for supplying power, and the like.

The shelf 2 has rails 8 that guide and support the printed board 3.
8', the printed board 3 is connected to a pictorial board 5 driven into the bank board 1 by a connector 4.

This printed board 4 is provided with a front connector 4' as a cable connection connector as required, and cable wiring within the unit or between units is performed using a cable connector 6 and a cable 7.

That is, conventionally, cable wiring to the front surface of the printed board was done after the unit was mounted on the gate.

FIG. 2 is an explanatory diagram of a wiring panel showing an embodiment of the present invention.

The same parts as in FIG. 1 are given the same reference numerals.

The wiring panel 10 has the same external dimensions as the shelf 2 originally for mounting printed boards, is provided with mounting screw holes 9, ventilation holes 11, and has a front connector 4' mounted thereon.

As shown in the figure, the wiring panel 10 is a metal chassis on which the backboard 1 and printed board 3 are not mounted, and assuming that the printed boards are fully mounted on the shelf 2, the front connector 4' is completely mounted. It has been implemented.

The ventilation hole 11 is useful when the wiring panel 10 is mounted on a gate together with other units, and the cable wiring is carried out first, and only a portion of the wiring panel 10 is not mounted on a printed board. .

FIG. 3 is a partially cutaway perspective view illustrating a situation in which the wiring panel is mounted on the gate.

The same parts as in FIG. 1 are given the same reference numerals.

A wiring panel 1 is installed in place of the unit at the gate 21 where a plurality of units on which printed boards are already mounted are mounted.
0 is mounted on each of the upper and lower tiers, and is screwed into the screw hole 9 that is originally used to attach the unit.

The front surface of the wiring panel 10 shown in the figure is the cable wiring surface that connects the front connector, and the wiring cable 7
Cable holders 22 and 27 that support the cables are arranged vertically and horizontally.

This cable holder 22' is provided with a large number of comb-shaped sections 23 into which the distribution cable 7 is drawn and fixed.

The wiring panel 10 is attached to the gate 21, and cable wiring is performed to connect the front connectors in advance.The cable connector is then removed from the front connector, and the unit with the printed board mounted thereon is replaced with a replacement cable connector that is mounted on the unit. By connecting to the front connector of the printed board that is installed, cable wiring work to the unit on which the printed board is mounted can be performed.

As is clear from the above embodiments, according to the present invention, cables can be wired between the front connector and the front connector by using a wiring jig instead of the unit, which shortens the inventory period for printed circuit board backboards, etc. It becomes possible to save on the overall cost required for assembly including wiring work.
