Description

[Detailed description of the invention] The present invention relates to a harness arrangement structure for a room lamp that is attached to a foldable front window. By providing a connector in the middle of the branch harness that passes through the frame of the type window and leading to the room lamp, and removably fixing it so that it faces the inner surface of the window side frame, the above can be achieved even when the window is folded down. This relates to a device that prevents the harness from breaking if the connector is removed.

A four-wheel drive vehicle configured to be suitable for off-road driving has a front window that can be folded forward and a hood covering the passenger compartment.When the window is folded down and the hood is removed, the inside and outside of the passenger compartment can be seen. Some cars are now able to enjoy driving in a fully open state with no obstacles separating them.
In such vehicles, the interior lamp is attached to the upper frame of the folding window, and the harness for powering it is therefore branched off from the main harness that runs below the instrument panel. Pull out the branch harness from the cowl panel etc. near the bottom of the wind side frame.
This is passed through the window side frame and connected to the room lamp mentioned above.

By the way, the hinge of the above-mentioned foldable front window is provided in the front of the window, that is, on the top surface of the cowl outer panel, so when the window is tilted forward, the bottom surface of the wind frame rises, and the entire length of the path through which the branch harness passes through the window. It will be longer than when it is standing. Therefore, if the length of the branch harness is set to match the total length of the path when the window is erected, an unreasonable tensile force will be applied to this harness when the window is folded down, and this This will cause the harness to break. To prevent such inconvenience,
It may be possible to leave some room in the length of the branch harness mentioned above, but in that case, when the window is upright, the slack harness will be exposed near the bottom of the window side frame, which is undesirable for the interior design. In addition to this, there was also the problem that this loose harness could get caught between the lower surface of the windside frame and the cowl panel, causing damage to the harness.

This invention was devised under the above circumstances, and its purpose is to avoid the inconvenience of tensile force being applied to the harness when the window is folded down, and to avoid damaging the interior design. To provide a structure for arranging a harness for a room lamp attached to a retractable front window.

In order to achieve this purpose, in this invention,
The following technical measures have been taken:

That is, the present invention has a wind frame consisting of an upper frame, both side frames, and a lower frame, and the lower frame is hinged to the vehicle body so that it can be tilted forward. This is an arrangement structure of a harness leading to the room lamp of a foldable front window with a room lamp attached to the frame, in which a box-shaped clamp is buried and fixed in the inner surface of the side frame with its opening facing. At the same time, a branch harness that branches to the room lamp is branched from the main harness and is exposed inside the vehicle interior, and a first part that extends from the opening of the clamp to the inside thereof, and a first part that extends from the inside of the clamp to the side frame. It is divided into a second part that passes through the interior and reaches the room lamp, and these parts are connected and separated by a connector, and this connector can be attached and detached by facing the holding means provided in the clamp from the opening. It is characterized by being held in

As described above, by providing the harness connector in the middle part of the branch harness, the branch harness can be separated into a part close to the trunk harness and a part close to the room lamp. Therefore, if the branch harness is separated at this connector portion when the retractable window is folded forward, the inconvenience that occurs in the conventional case where unreasonable tensile force is applied to the branch harness and the branch harness breaks can be avoided. Moreover, this connector is detachably fixed at a position facing the inner surface of the window side frame, so when the window is tilted forward, this connector can be removed from its fixed position and separated. It is very easy to operate and to secure the connected connectors in place when the window is erected.

Embodiments of the present invention will be specifically described below with reference to the drawings.

The wind frame 1 has a closed cross-section structure including an inner panel 2 and an outer panel 3.
By interposing a hinge 7 between the outer panel 5 of the lower frame 4 and the upper surface of the cowl outer panel 6 on the vehicle body side, the lower frame 4 can be tilted forward and rotated. Further, as shown in FIG. 1, a room lamp 10 is installed near the center of the inner panel 9 of the Atsupa frame 8, and the power supply to this lamp is hidden below the instrument panel 12. , and a branch harness 11 that branches off from a trunk harness 13 that bundles harnesses to various electrical components.
For example, it is pulled out from a hole 12a made in the top surface of the instrument panel 12, etc., and guided to the room lamp 10 via the inside of the closed section of the side frame 14 or the top frame 8 of the wind frame 1. It is done by twisting. In the present invention, the branch harness 11 is divided into a first part 11a near the trunk harness 13 at the part where it enters the inside of the windside frame 14, and a second part 11b near the room lamp 10, and these parts are separated. The connection is made by a connector 15, and the connector 15 is removably fixed so as to face the inner surface of the window side frame 14.

3 to 5 show specific examples of the harness clamp 16 for removably fixing the connector 15. The clamp 16 is preferably made of a slightly elastically deformable resin or the like, and has an overall box-like shape with an approximately rectangular interior space capable of accommodating and holding the connector 15. An outward flange 18 is provided on the outer periphery of the opening 17. The clamp 16 is fitted into a four-sided mounting hole 20 formed in the inner panel 19 of the wind side frame 14 so that its outer periphery fits snugly. When attached, the outward facing collar 18 abuts against the outer surface of the inner panel 19. As shown in FIG. 4, an engaging piece 21 hooked on the inside of the inner panel 19 and a push piece 22 elastically engaged with the edge of the mounting hole 20 of the inner panel 19 are attached to the clamp 16. It is advantageous to provide the clamps 16 near the flanges 18 on opposite sides of the outer walls, since this prevents the clamps 16 from accidentally falling out of the mounting holes 20 due to vibration or the like.

Now, the clamp 16 is provided with a holding means 23 that can detachably hold the connector 15 in its holding space. In the illustrated example, since the connector 15 has a substantially T-shaped cross section in which a wide portion 24 and a narrow portion 25 are stacked as shown in FIG. 3, the wide portion 24 A pair of opposing holding pieces 26 are provided on the inner surface 27 of the clamp 16 and have a hook 28 for hooking the shoulders of the clamp 16 . That is, this holding piece 26
As shown in FIG. 3, extends from the inner surface 27 toward the outlet opening at a distance approximately equal to the width of the wide portion 24 of the connector 15, and extends from the inner surface 27 to the height of the wide portion 24. An inwardly protruding hook portion 28 is formed at a portion corresponding to the portion. This holding piece 26 should be made of a slightly elastically deformable material such as resin. Therefore, the connector 1 is inserted between the opposing holding pieces 26.
When the connector 15 is pushed in with its wide part 24 facing down, the shoulder of the wide part 24 is elastically hooked on the hook part 28 of the holding piece, and the connector 15 is held.

Note that the second portion 11 of the branch harness 11 extending from the connector 15 held by this clamp 16
b extends inside the closed section of the wind side frame 14, so as shown in FIG. It's open.

When folding the folding front window forward, as shown in FIG.
After removing the connector from the harness clamp 16 and separating the male and female connectors 15, the window is folded down as shown in FIG. Conversely, in the normal state with the window upright, the male and female connectors 15 are connected and held by the clamp 16. Clamp 16
Since the connector 15 held in the window faces the inner surface of the windside frame, it is easy to remove it from the clamp or to hold it in the clamp again.

As described above, according to the arrangement structure of the harness for the room lamp attached to the foldable front window of the present invention, the harness leading to the room lamp is routed through the first part on the trunk harness side and the room side frame. Since the second part leading to the room lamp can be separated at the connector part, when these parts are separated, the connection between the second part on the movable side and the first part on the vehicle body side is severed, and therefore the window This has the effect that the foldable front window can be conveniently brought forward without causing problems such as tension acting on the harness due to tilting and causing the harness to break.

The connector that connects the first part and the second part of the harness is held in a clamp embedded in the inner surface of the wind side frame so as to face the inner surface of the side frame, so the connector can be taken out and attached to the harness. It is extremely easy to separate the connector into the first part and the second part, and to accommodate and hold the connector that connects the first part and the second part again in the clamp. Since no protrusions are formed on the wind side frame, safety is maintained.

Furthermore, since the harness leading to the room lamp is separated into the first part on the trunk harness side and the second part on the room lamp side, and these are connected with a connector, the front window can be used as is. There is no longer a need to use a long branch harness to allow for extra room when folding the vehicle forward, and there is no need for the harness to unsightly hang on the instrument panel when the front window is raised.

Note that the scope of the present invention is not limited to the embodiments shown in the drawings, and various design changes can be made to the type of connector or the clamp for holding the connector as necessary.

In addition, in the illustrated example, the branch harness branched from the trunk harness is pulled out through a hole drilled on the top surface of the instrument panel. It may be pulled out through a hole provided in this and led to the vicinity of the connector clamp in the wind side frame.
