Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a device for fixing and fixing a connector which is used in an air conditioner including an indoor unit and an outdoor unit, for electrically connecting each unit, which is a body to be wired, and an external lead wire.

[0002]

[Prior Art]

 For example, in an air conditioner including an indoor unit and an outdoor unit, the units to be wired are electrically connected to each other by external lead wires that are crossovers.

A connector is provided between each unit and the external lead wire to electrically connect them. If this connector is exposed from each unit, the external appearance of the unit is impaired, so this connector is mounted and fixed inside the unit. That is, when installing the air conditioner, each unit is installed and arranged at an appropriate site, and the necessary wiring work and electrical wiring connection work are performed. The electric wiring connecting work includes a work of connecting the connector and the external lead wire and a work of attaching the connector to the unit.

That is, a component lead wire is extended from each of the electric components provided in each unit, and this end portion is connected to the connector at the time of factory shipment. Therefore, at the installation site of the air conditioner, it is sufficient to connect the external lead wire to the connector, and easy installation of the connector leads to improved workability.

Conventionally, as shown in FIG. 5, the indoor unit body 1 is composed of a rear plate body 2 and a front panel 3. The rear plate body 2 is attached and fixed to the wall surface of the air-conditioned room, and the front panel 3 is detachably attached to the rear plate body 2.

A connector bushing 4 is detachably attached to a side surface on the right side of the front panel 3 to close a notch 5 opening therein. A main body bushing 6 is detachably attached to a side surface portion of the rear plate body 2 adjacent to the cutout portion 5 to close an opening portion 7 opening therein.

With the connector bushing 4 removed, a part of the connector base 8 is exposed in the cutout portion 5, and the cord clamp 9 is exposed with the main body bushing 6 removed. Then, the external lead wire 10 is extended from the connector base 8 and the cord clamp 9. As shown in FIG. 6, reference numeral 11 denotes an electric component base provided in the indoor unit body 1, and an electric component (not shown) is attached to the back side of the electric component base. Reference numeral 12 denotes a connector attached to the connector base 8, to which a component lead wire 13 extending from the electrical component is connected in advance. The connector base 8 is removably attached to a pair of upper and lower fixing recesses 14, 14 provided adjacent to the electric component base 11.

That is, the projections 15 and 15 are integrally provided at the upper and lower ends of the connector base 8, and the projections 15 and 15 are pushed against the fixing recesses 14 and 14 using a tool such as a flat-blade screwdriver to rotate and forcibly insert. By doing so, this mounting and fixing is performed. Similarly, when removing, it is necessary to forcibly rotate the tool and pry it open. The above-mentioned cord clamp 9 presses the external lead wire 10 whose end is connected to the connector 12 to firmly fix it.

[0009]

[Problems to be solved by the device]

 As such a wiring work sequence, the connector 12 already connected to the component lead wire 13 of the electrical component is pulled out of the unit main body 1 and fixed to the connector base 8.

On the other hand, the outer end wire 10 is stripped of its end coating to form a bare wire, which is extended to the connector base 8. The end portion of the external lead wire 10 is connected to the connector 12, and the cord clamp 9 is screwed to fix the end portion of the external lead wire 10 by pressing.

Therefore, all of the attachment of the connector 12 to the connector base 8, the connection of the external lead wire 10 and the attachment of the cord clamp 9 are performed outside the unit body 1.

After these operations are completed, the connector base 8 and the components related thereto are inserted into the unit body 1, and the protrusions 15 and 15 are forcibly inserted into the fixing recesses 14 and 14 to be fixed. Finally, the connector bushing 4 and the main body bushing 6 are fitted in, and the electrical wiring work is completed.

By the way, the problem is that the connector 12 connecting the component lead wire 13 of the electrical component and the external lead wire 10 together with the connector base 8 and the cord clamp 9 is provided with fixing recesses 14 and 14 which are mounting portions of the main body 1. It is a work to attach to.

That is, in order to forcibly insert and mount the projections 15 and 15 provided at the upper and lower ends of the connector base 8 into the fixing recesses 14 and 14 of the main body 1, it is necessary to use a tool such as a minus driver for example. There is. And it is difficult to work unless the worker is facing the work surface.

Further, since the air conditioner is already installed, it is necessary to inspect or replace the electric component for some reason. With the front panel 3 removed, the connector 12 to which the component lead wire 13 and the external lead wire 10 are connected must be removed from the connector base 8.

That is, the work is carried out in the opposite manner to the above-described mounting work, but at this time, the worker also holds a tool such as a flat-blade screwdriver, and the right side surface of the unit main body 1 which is the work surface It is easy to work when done in the opposite state.

However, the indoor unit is not always installed at a site where a sufficient working space can be secured on the right side surface of the main body 1. Due to the installation side, the wall surface in the direction orthogonal to the right side surface of the main body 1 is often close to, that is, the corner or ridge of the air-conditioned room, or some kind of attachment.

In this state, it is impossible for the operator to directly face the eye, and it is impossible to visually check it, so that the operator has to work almost by groping. Workability is poor, and there are concerns about reliable mounting and fixing.

The present invention has been made under such circumstances, and its purpose is to attach a connector, connect an external lead wire, and attach a connector base to which a cord clamp is attached to a body to be wired. It is an object of the present invention to provide a connector mounting and fixing device that enables the necessary work to be performed easily and reliably even when groping, without facing the work surface when detaching.

[0020]

[Means for Solving the Problems]

 In order to achieve the above object, the first invention is an apparatus for attaching and fixing a connector for electrically connecting a wiring target and an external lead wire to the wiring target, wherein the external lead wire and the wiring target are connected to each other. Attach the connector in an electrically connected state to the connector base, provide a latching claw on this connector base, and the latching claw of the connector base is detachably latched to the above-mentioned wiring body to be wired on the connector base. The connector mounting and fixing device is characterized in that a hooking hole for attaching to the connector is provided.

According to a second aspect of the invention, the wiring base body is covered with a detachable cover at a connector base mounting portion, and the connector base is in a state in which a latching claw is not properly latched in a latching hole. The connector mounting / fixing device according to claim 1, further comprising a protrusion that obstructs the mounting of the cover and regulates the mounting.

[0022]

[Action]

 The hooks of the connector base, to which the external lead wires are connected and the connector that is electrically connected to the wiring target, is attached, can be locked in the locking holes provided in the wiring target, without the need for tools. Moreover, there is no need to face the work surface.

[0023]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. As the wired body, for example, an indoor unit of an air conditioner is targeted, and the shape structure of the unit main body 1 as described above with reference to FIG. 5 is applied as it is.

First, as shown in FIG. 2, with the front panel 3 removed, the rear plate body 2 is exposed. The heat exchanger 16 occupies most of the front surface side, and the electric component base 11 is provided on the right side portion. A large number of electric components (not shown) are attached to the back surface side of the electric component base 11, and the respective component lead wires 13 are extended to the front surface side of the component base 11.

The ends of the component lead wires 13 are previously connected to the connector 12, and the connector 12 is attached to a new connector base 20. Further, an external lead wire 10 having a bare wire at its end is extended to the connector base 20 and connected to the connector 12. The mounting screw 17 mounts the cord clamp 9 on the connector base 20 and presses the end portion of the outer lead wire 10.

As described above, the connector 12 in which the component lead wire 13 and the external lead wire 10 are connected to the connector base 20 is attached, and the cord clamp 7 is attached to the connector base 20. Attach it to the unit body 1. At this time, the main body bushing 6 is removed and the opening 7 is left open.

As shown in FIG. 1, a rear side portion of the electric component base 11, which is a lower portion of the right side surface of the rear plate body 2, has a pair of parallel positioning protrusions 21 and 21 with a predetermined interval in the vertical direction. Is projected. The engaging projection 22 is integrally provided between the positioning projections 21 and 21 and only on the front side. An engaging hole 23 is provided in the engaging projection 22. A pair of auxiliary engaging holes 24, 24 are provided between the positioning protrusions 21, 21 and vertically apart from each other only on the rear side.

About half of the front side of the connector base 20 is a connector mounting step portion 20a for mounting and fixing the connector 12 on the rear surface side in the drawing by an appropriate means. The remaining rear half is an external lead wire mounting portion 20b along which the end portion of the external lead wire 10 extends along the front surface side.

The external lead wire mounting portion 20b is integrally provided with a boss portion 25 having a screw hole, and a mounting screw 17 for screwing the cord clamp 9 is screwed into the screw hole.

On the front end of the connector mounting step portion 20a of the connector base 20, a hook claw 26 is integrally projected. The hooking claw 26 can be hooked and unhooked in the hooking hole 23 provided in the hooking projection piece 22.

On both sides of the boss portion 25 of the external lead wire mounting portion 20b, a pair of auxiliary claws 27, 27 are provided on the back surface side thereof so as to project. These auxiliary claws 27, 27 can be freely engaged with and disengaged from auxiliary engagement holes 24, 24 provided between the positioning protrusions 21, 21.

Furthermore, triangular projections 28a 1 and 28a 2 are integrally provided on the upper and lower ends of the connector mounting step 20b. The heights (projections) of the projections 28a, 28a are slightly lower than the upper end (projection end) of the engaging projection 22 when the connector base 20 is attached to a predetermined portion of the rear plate body 2. Must be set.

A triangular protrusion 28b is integrally provided on one piece of the external lead wire attaching portion 20b. The height (projection) of the protrusion 28b is such that the connector base 20 is attached to a predetermined part of the rear plate body 2 and the opening 7 of the rear plate body 2 is closed by the main body bushing 6 while the main body bushing 6 is Must be set apart from the claw portion 6a.

Then, after the unit body 1 is installed and fixed at a desired position, the front panel 3 is removed, and the connector 12 connected to the component lead wire 13 is attached to the side portion of the rear plate body 2 where the body bushing 6 is removed. Take it out.

The connector 12 is attached and fixed to the connector mounting step portion 20 a of the connector base 20, and the external lead wire 10 is connected to the connector 12 along the external lead wire mounting portion 20 b. Then, the cord clamp 9 is applied to the end portion of the external lead wire 10, and the mounting screw 17 is screwed to press and fix the external lead wire 10 to the external lead wire mounting portion 20b.

In such a state, the connector base 20 is directly moved to the right side surface of the rear plate body 2. That is, the upper and lower ends of the connector base 20 are inserted between the positioning protrusions 21 and 21, and the front end is pressed along the engaging protrusion 22.

As shown in FIG. 3, the hook claws 26 of the connector base 20 are inserted into the hook holes 23 of the hook projections 22 and are hooked. Then, again, the auxiliary claw 27 engages with the auxiliary engaging hole 24. Therefore, the connector base 20 is attached and fixed to a predetermined position of the rear plate body 2 with one touch. In this state, the wiring work is completed, and finally, the front panel 3 is attached, and the main body bushing 6 shown in FIG.

Even if there is not enough working space on the right side surface due to the installation site of the unit main body 1, that is, there is no space for the operator to directly face the right side surface, which is insufficient for visual inspection. However, the connector base 20 can be easily mounted by groping. Of course, even when the connector 12 is taken out for inspection of electric parts, the same workability can be obtained.

As a result of the groping work, it may be possible to make a mistake in finishing the work without mounting the connector base 20 at a predetermined position. However, even in such a case, the connector base 20 informs the worker of a work defect.

For example, as shown in FIG. 4 (A), although the hook claw 26 is actually placed on the upper end portion of the hooking projection piece 22, the auxiliary hook 27 is inserted into the auxiliary hooking hole 24. When the connector base 20 is attached, it may be mistaken for the completion of the attachment of the connector base 20.

After that, when the operator tries to attach the front panel 3, the front panel 3 (connector bushing 6) comes into contact with the upper end of the triangular protrusion 28 a projecting from the connector base 20, and the normal position The floating state makes it virtually impossible to completely attach the front panel 3.

Even when the main body bushing 6 is attached, the claw portion 6a does not reach the regular hooking position shown by the chain double-dashed line in the figure by abutting the upper end of another triangular protrusion 28b. Therefore, the body bushing 6 cannot be attached. From the above, the worker is notified of the poor mounting of the connector base 20, and the connector base 20 is remounted again.

As shown in FIG. 3B, the connector base 20 is in the middle of bending the engaging projection piece 22, and the engaging claw 26 is lower than the upper end portion of the engaging projection piece 22. However, the same is true in the case of an improper attachment that does not engage with the engagement hole 23.

That is, even if the front panel 3 is to be attached, the front panel 3 abuts on the upper end of one of the protrusions 28a, and the panel 3 cannot be attached. Even if the main body bushing 6 is mounted, this claw portion 6a abuts on the upper end of another protrusion 28b and does not reach the regular hooking position shown by the chain double-dashed line. From the above, the operator can conclude that the connector base 20 is not properly attached, and will re-attach the connector base 20 again.

Further, depending on the installation location of the indoor unit, necessary work can be performed without removing the front panel 3. That is, the connector bushing 4 and the main body bushing 6 may be removed from the side surface of the front panel 3.

Also at this time, if there is a mounting failure of the connector base 20, the projections 28a and 28b prevent the mounting of the connector bushing 4 and the main body bushing 6 and inform the operator of the mounting failure of the connector base 20. To do.

In the above embodiment, the indoor unit of the air conditioner is applied as the wiring object, but the present invention is not limited to this, and the point is that the electrical components and the external lead wires are electrically connected. Any connector can be attached as long as it can be connected.

[0048]

[Effect of the device]

 As described above, according to the present invention, when the connector base, the external lead wire is connected, and the connector base to which the cord clamp is attached is attached to or detached from the body to be wired, it is easy to do without directly facing the work surface. In addition, the work can be performed reliably, and the workability can be improved.
