Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a room lamp that is attached to the ceiling surface of a car interior.

<<Prior Art>> Room lamps that are attached to the ceiling surface of a car interior have been known for some time.

To give an overview of this room lamp, as shown in FIG. The lens 4 includes a housing 3 that is attached to cover the lens, and a lens 4 that is attached to the housing 3. The base plate 2 is provided with a connector bracket 5 having a male part 5a of a connector that electrically connects the lamp bulb, and the ceiling surface 1 is provided with a connector bracket 5 that fits into the male part 5a of the connector bracket 5. A female part 5b is attached. Furthermore, a switch bracket 6 is provided on the base plate 2, and a switch 7 is attached to this bracket 6.

The connector bracket 5 is constructed as shown in FIGS. 8 to 10.

The connector bracket 5 is inserted into an opening 2a provided in the base plate 2. A resilient arm portion 8 is formed at the tip 5c of the bracket 5, and by sandwiching the base plate 2 from both sides between this arm portion 8 and a flange portion 9 formed at the intermediate portion of the bracket 5, the bracket 5 is attached to the base plate 2.

A terminal 10 connected to the male portion 5a is provided at the base end 5d of the bracket 5. Bracket 5
Support stays 11 are provided on both sides of the connector bracket 6 to support the switch bracket 6 at a constant height so as to cover the upper side of the connector bracket 5.

<<Problem to be solved by the invention>> By the way, in the room lamp having the above structure, the terminal 10 is provided at the base end 5d of the connector bracket 5, and the switch bracket 6 is provided so as to cover this terminal 10. , there is a risk of contact if the connector bracket 5 moves.

The outward movement (downward movement in FIG. 8) of the connector bracket 5 can be reliably prevented by the flange portion 9, but the inward movement can be prevented by the elastic Since it is only supported by the arm part 8, if the female part 5b of the connector is forced into the connector bracket 5, the connector bracket 5 may move inward and the terminal 10 may come into contact with the switch bracket 6. There is a point.

The present invention was devised in view of the above-mentioned problems, and an object thereof is to provide a room lamp that can reliably prevent electrical contact between a connector bracket and a switch bracket.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention has a base plate fixed to the ceiling surface of the vehicle interior, a lamp bulb attached to the base plate, and a lamp bulb attached to the base plate inside. a housing in which the lamp bulb is located, a lens attached to the housing so as to cover the lamp bulb, and a connector bracket that is attached to the base plate and includes a built-in male part of a connector for electrically connecting the lamp bulb. , comprising: a female part of the connector attached to the ceiling surface side and fitted with the male part; and a switch bracket attached to the base plate, covering the upper side of the connector bracket and having a switch attached thereto for connecting/disconnecting the lamp bulb. The present invention is characterized in that an abutment rib is provided on the switch bracket side of the connector bracket to ensure a constant interval so that these brackets do not come into contact with each other.

<<Operation>> In the room lamp having the above structure, the abutting rib provided on the connector bracket abuts the switch bracket, thereby ensuring a certain distance between the connector bracket and the switch bracket, thereby preventing them from coming into contact with each other.

<<Example>> Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 4 to 6, the room lamp of the present invention mainly includes a base plate 22 fixed to the front end of the interior ceiling surface 21, a lamp bulb 23 attached to the base plate 22, and a base plate 22. A housing 24 is attached to the plate 22 so as to cover the lamp bulb 23, and a lens 25 is attached to the housing 24 at a position facing the lamp bulb 23.
and a rearview mirror stay 26 fixed to the base plate 22. Housing 24
A switch 27 for connecting and disconnecting the lamp bulb 23 is provided on the rear end side 24a.

A lamp bulb 23 is mounted on the base plate 22.
A connector bracket 28 having a built-in male part 28a of a connector for electrically connecting the two is attached. A female portion 28b that fits into the male portion 28a is attached to the ceiling surface 21 side. Further, a switch bracket 29 is attached to the base plate 22 so as to cover the connector bracket 28. This switch bracket 29 has support stays 30 provided on both sides of the connector bracket 28.
a, 30b and a support stay 31 provided at the rear end 22a of the base plate 22. This switch bracket 29 includes a switch 27 provided at the rear end 24a of the housing 24.
The base of is fixed.

The connector bracket 28 is constructed as shown in FIGS. 1 to 3.

The connector bracket 28 is provided on the base plate 22 and inserted into the opening 22a. An arm portion 33 is formed at the tip 28c of the bracket 28. The arm portion 33 is made of an elastic resin material and is bent from the bracket tip 28c toward the base end 28d. A flange portion 34 is formed in the middle portion of the bracket 28 and abuts the peripheral edge of the opening 22a from the inside. That is, the bracket 28 is attached to the base plate 22 so as to be held between the arm portion 33 and the flange portion 34 from both sides.

A terminal 35 connected to the male portion 28a of the connector is attached to the base end 28d of the bracket 28, and a lead wire 36 extending from this terminal 35 is connected to the lamp bulb 23 and the switch 27. Further, the base end 28d is provided with an abutment rib 37 extending toward the switch bracket 29 covering the upper side thereof. This contact rib 3
7, its tip 37a is connected to the switch bracket 2.
9, and maintains an interval equal to the length of the abutment rib 37 between the proximal end 28d of the connector bracket 28 and the switch bracket 29.

In the room lamp configured as described above, when attaching the base plate 22 to the ceiling surface 21, the male part 28a of the connector bracket 28 is attached at the same time.
and the female part 28b on the ceiling surface 21 side are fitted together,
If the mutual fit is poor, the connector bracket 28 will be forced inward (upward in FIG. 1). Although the terminal 35 and the switch bracket 29 try to come into contact with each other, since a certain distance is maintained between them by the abutting rib 37, they can be reliably prevented from coming into contact with each other.

<<Effects of the invention>> As explained above, according to the room lamp of the invention, the contact ribs are provided on the switch bracket side of the connector bracket to ensure a constant interval so that these brackets do not come into contact with each other. This has the advantage of reliably preventing electrical contact between the connector bracket and the switch bracket.
