Description: TECHNICAL FIELD The present invention relates to a wiring device formed by modularizing each wiring component used for wiring a plurality of electrical components.

[Prior Art] Conventionally, in various electrical equipments such as OA equipments such as copying machines and printers, as shown in FIG. 13, a plurality of electrical components 2 (specifically, 1a to 2c) are provided in a device frame 1. And the like) are provided, and the wiring harnesses 3 are used as wiring components that enable the electric components 2 to be energized.

[Problems to be Solved by the Invention] However, in such a conventional wiring component,
Since the wire harness 3 is long and has an irregular shape, when the wire harnesses 3 are individually routed, the respective wire harnesses 3 are
Is easily entangled, and its handling is inherently troublesome,
During the wiring work of the wire harness 3, the wire harness 3 is routed to a position on the side of the electrical equipment 2 that is the work target. However, when the wired wire harness 3 moves unnecessarily, other electrical components 2 and the like Therefore, in order to prevent this, it is necessary to bind and hold the wire harness 3 by the clamp members 4 at various places, and accordingly, the wiring work itself becomes troublesome. There's a problem.

Furthermore, when connecting each electric component 2 and the wire harness 3, the connector 5 on the side of the electric component 2 and the connector 6 on the side of the wire harness 3 are connected, but both connectors 5 and 6 are connected. Both connectors 5 and 6 are normally free.
Must be connected with both hands held,
There is a problem in that the work of connecting the connectors 5 and 6 is a two-handed work, which is troublesome. Reference numeral 7 is a connector for connecting the wire harnesses 3 to each other.

[Means for Solving Problems] The present invention has been made by paying attention to the above problems, and when performing wiring work to a plurality of electrical components, wiring components such as a wire harness are arranged. (EN) Provided is a wiring device capable of simplifying a searching operation and a connector connecting operation.

That is, the present invention is a wiring device for wiring a plurality of electrical components arranged on a device frame, wherein a wiring component forming an energization path to each of the above-mentioned electrical components and a disposition location of each electrical component are provided. Corresponding to the module case which is continuously formed along the vicinity and accommodates and holds the above-mentioned wiring parts and is detachably attached to the corresponding attachment part of the equipment frame, and the vicinity of the installation position of each electrical component. The wiring device includes a wiring component side connector fixedly arranged in the module case portion and connected to each electrical component side connector.

In such technical means, various wiring components such as a wire harness may be used as the wiring component, but from the viewpoint of reducing the number of wiring components, for example, a plurality of electrical components are mounted on an insulating substrate. It is desirable to use a wiring board on which a corresponding pattern conductor for wiring of a component is formed. Regarding the wiring pattern conductor of this wiring board, a wiring path corresponding to each target electrical component is formed of a conductive material (including one in which a plurality of electrical components are arranged in parallel and in series in one wiring route). , It is necessary to design to prevent short-circuiting of each wiring route, and wiring pattern conductors should be installed not only on one side of the insulative board but also on both sides of the insulative board. It does not matter if the flexible substrate has a multi-layered structure and is provided inside the insulating substrate. Further, it goes without saying that the wiring density and the pattern shape of the wiring pattern conductor can be appropriately changed in design.

As for the module case, as long as it is a member having a certain degree of rigidity to secure the space for accommodating the wiring components, the shape and mounting structure of the wiring components may be appropriately changed. From the viewpoint of preventing damage to electrical equipment due to the outflow of electromagnetic radiation, it is desirable to apply electromagnetic shielding treatment to the module case, and it is also possible to suppress reduction in the allowable current capacity of wiring components such as wire harnesses. From the point of view, it is desirable to design such that a vent hole is formed in a part of the module case to avoid an increase in ambient temperature in the module case due to heat radiation from the wiring components. Furthermore,
Wiring parts are AC primary side wiring or high voltage wiring system and DC
When both wiring systems are included, the module case is insulated for each wiring system from the viewpoint of avoiding the influence on one wiring system when another wiring system fails. It is desirable to design it. Further, as the means for holding the wiring component housed in the module case, the wiring component may be formed integrally with the module case as long as the wiring component is positioned and held at a predetermined housing position. However, the design may be changed appropriately even if it is a separate body. Further, when connecting the wiring component side connector and the electrical component side connector, it is necessary to provide at least an opening for exposing the wiring component side connector to the outside in the module case.

Further, as the connector for connecting the wiring component and the electrical component, various types including general plug jack type and card edge type may be used,
For example, in the case where the wiring component is a wiring board, from the viewpoint of reducing the number of components of the wiring component side connector, there is a card edge type in which the end of the wiring pattern conductor of the insulating substrate can be used as it is. desirable. Also, the insertion direction of the wiring component side connector may be appropriately selected, but if the connection workability of the connector on each electrical component side is taken into consideration, the insertion direction of all or most of the electrical component side connectors will match. It is desirable to arrange the wiring component side connectors in parallel. Furthermore, it is necessary to design the electrical component side connector and the wiring component side connector so as to maintain a good connection state between them, and a retainer mechanism that enhances the connection holding force itself or maintains the connection state between the two. May be provided on either side.

Furthermore, regarding the connection structure between the wiring component and another control board or the like, an existing wiring material is used, and the connection end of the wiring component and the wiring material are soldered or appropriately designed as long as they are connected by a connector. You can change it. In this case, when the wiring component and the wiring material are connected by soldering, it is desirable to provide a means for preventing external force from directly acting on the soldered portion in order to prevent damage to the soldered portion. .

[Operation] According to the technical means as described above, each wiring component corresponding to each electrical component is housed and held in the module case, and the connector on each wiring component side is fixedly provided at a predetermined portion of the module case. As a result, the wiring parts for connecting the electrical components are made into a module case to form one integrated wiring device, and if this wiring device is fixed at a predetermined position on the equipment frame, the wiring component side connector It will be uniquely set near each electrical component,
The connection work between the two can be performed by slightly moving only the electrical component side connector.

Next, the case of assembling the wiring device K according to this embodiment will be described. First, the connector 51 as the wiring component side connector 50 is provided with the corresponding connector connection opening 40 (40a).
To 40e), and then the wire harness 11 is housed and held in the upper compartment 33a of the module case 30, while the card edge 55 as the wiring component side connector 50 and the flat wire 20 have corresponding connector connection openings.
40 (40f to 40k) and the wiring board 15 in the lower compartment 33b of the module case 30 so as to pass through the drawing hole (not shown).
Should be held and fixed.

In this state, as shown in FIG. 8, the wire harness 11 is held by the holding plate 37 in the compartment 33a and each connector 51 of the wire harness 11 is held.
Is positioned and fixed in the connector connection opening 40, the wire harness 11 will not move unnecessarily in the compartment 33a or unnecessarily protrude from the compartment 33a. Further, since the wiring board 15 is positioned and held in the horizontal and vertical directions along the gap 39 between the holding walls 38 arranged in the compartment 33b in the horizontal and vertical directions, the wiring board 15 is held in the module case 30. Although it can be detached to the insertion opening 31 side (the device frame 1 serves as a detachment prevention member when the device frame 1 is attached), it does not move unnecessarily in the compartment 33b.

When performing wiring work of each electrical component 2 on the equipment frame 1 using the wiring equipment K assembled in this way, as shown in FIGS. The wiring device K described above is placed in the module case
The wiring harness 11 and the wiring board 15 as wiring parts are connected to a control board (not shown) and the like, and the connector 5 of each electric component 2 is connected to the corresponding wiring part. It may be connected to the side connector 50.

In such a wiring work process, since the wiring device K is a modularized wiring component 10 of each electrical component 2, if the wiring device K is attached to a predetermined portion of the device frame 1. The wiring component 10 in the wiring device K is uniquely positioned with respect to the device frame 1. Therefore, unlike the conventional case, the wiring harness (see reference numeral 3 in FIG. 13), which is a wiring component, is not individually wired for each electrical component 2, and the wiring harnesses are entangled with each other during wiring work. Alternatively, when installing a plurality of wire harnesses, there is no need to perform a work of binding and holding the wire harness group using a clamp member.

Further, since the wiring component side connector 50 corresponding to each electric component 2 is fixedly provided in the wiring device K portion located in the vicinity of the installation position of each electric component 2, it is mounted on the equipment frame 1. The connector 5 of each electrical component 2 is slightly moved with one hand to complete the connection of both connectors 5 and 50. At this time, it is possible to set the length of the wire harness between the electrical component side connector 5 and the electrical component 2 to be extremely short. It also eliminates the need to wander, and makes connecting the connectors 5 and 50 easier.

In addition, in this embodiment, since the wiring board 15 in which a plurality of energizing paths are integrated is used as the wiring component 10, wiring components such as the wire harness 11 are all provided for each electrical component 2. Not only can the number of wiring components be reduced as compared with the case where it is used, but the work of incorporating the wiring components 10 in the module case 30 is also simplified.

Also, in this embodiment, the module case 30
Since the electromagnetic shield processing is applied to the, even if electromagnetic waves are generated from the wiring component 10 in the module case 30,
This electromagnetic wave will flow to the ground side through the wall of the module case 30, so that the electromagnetic wave can be effectively prevented from flowing out of the module case 30. For this reason, it is not necessary to wind a shield tape around the wiring component 10 or to apply a shield treatment such as using a shielded wire, and the various electrical components 2 are correspondingly EMI (Electro Magnetic Interf
It is possible to easily prevent the situation of giving an obstacle.

Further, the module case 3 for partitioning the upper compartment 33a
Since an appropriate vent hole 34 is opened in the upper wall of 0, even if the temperature inside the compartment 33a rises due to the heat generated from the wire harness 11, the hot air is discharged to the outside through the vent hole 34. Therefore, the temperature rise in the compartment 33a can be effectively suppressed. Therefore, it is possible to prevent the allowable current capacity of the wire harness 11 from being lowered due to the increase in the ambient temperature.

Furthermore, the module case 30 includes two compartments 33a,
Since 33b is partitioned by the insulating partition plate 32, even if the coating tube of the wire harness 11 is damaged, excessive current or voltage is applied to the wiring board 15 side. This situation is effectively avoided.

Further, in this embodiment, since the card edge connector is used as a part of the electrical component side connector 5, the insulating substrate 16
It becomes possible to form the card edge contact 55 at the same time when the wiring pattern conductor 18 is formed on the wiring board 15. Therefore, for the wiring board 15, the wiring component side connector 50 does not require its own manufacturing process, and Since there is no need to install a separate component as the wiring component side connector 50, the wiring component side connector
It is possible to reduce the number of 50 component parts.

Further, in this embodiment, the wiring component side connector 50 corresponding to each electrical component 2 arranged in the equipment frame 1 is provided.
Since they are arranged side by side in the same direction, it is possible to make the insertion direction of the connector 5 of each electrical component 2 common, and the connection work of the connector 5.50 is easier by that much. .

Further, as shown in FIG. 9, for example, if a retainer mechanism 60 that holds the connected state of both of the electrical component side connector 5 and the wiring component side connector 50 is provided, vibration of electrical equipment may occur. The concern that the connectors 5 and 50 are unnecessarily disconnected can be effectively avoided. The retainer mechanism 60 shown in FIG. 9 is applied between the electrical component side connector 5 configured as a card edge type connector and the card edge 55 as the wiring component side connector 50. For example, the electrical component side connector 5, a pair of elastic protrusions 61 on which the wiring board 15 is elastically sandwiched are disposed on the side of the housing 71, and the V-shaped locking protrusions are provided inside the tips of the elastic protrusions 61.
62 is formed, and a holding and locking hole 63 is opened at a corresponding portion of the wiring board 15, and the above-mentioned locking projection 62 is removably locked in this holding and locking hole 63. In this type, the elastic projection 61 and the holding locking hole 63 are asymmetrically arranged with respect to the center line in the insertion direction of the connectors 5 and 50, so that the electrical component side connector 5 is erroneous with respect to the wiring component side connector 50. Insertion can also be prevented.

Further, in this embodiment, since the insertion direction of the electrical component side connector 5 coincides with the mounting work direction of each electrical component 2, for example, as shown in FIG. While a guide protrusion 72 is provided on a part of the module, a guide receiving portion 73 is formed on the outer surface of the module case 30 corresponding to the guide protrusion 72, and by fitting the two, the electrical component side connector 5 and the wiring component side connector 50 are connected. Providing a guide mechanism 70 that uniquely sets the connection position, and
As shown in FIGS. 11 and 12, the wiring component side connector 50
A play structure that allows the electrical component 2 to absorb a slight positional deviation of the electrical component side connector 5 at a position corresponding to (51, 55), for example, a locking clip 75 is provided on the electrical component side connector 5. On the other hand, a mounting hole 77 slightly larger than the clip diameter of the locking clip 75 is formed in the support bracket 76 attached to each electrical component 2, and the locking clip 75 is inserted and locked in the mounting hole 77. If it is attached with such a structure, it becomes possible to perform the connecting work of the connectors 5 and 50 at the same time in the working process of mounting the respective electrical components 2 of the equipment frame 1.

[Effects of the Invention] As described above, according to the wiring device according to the present invention, each wiring component of the plurality of electrical components mounted on the equipment frame is modularized into one, and therefore, for each electrical component. There is no need to individually perform wiring work, and even if a wire harness is used as a wiring component for each electrical component, the wire harnesses are entangled with each other, and it is not necessary to use a clamp member during the wiring work, The wiring workability of each electric component can be greatly improved.

Further, according to the present invention, since the wiring component side connector is fixedly provided in the wiring device portion located in the vicinity of the disposition position of each electric component, when connecting each electric component and the wiring component, Since only the electrical component side connector needs to be moved slightly, the connection work between the electrical component and the wiring component becomes one-handed work, and the workability of connecting each electrical component and the wiring component is greatly improved compared to the conventional method. be able to.
