Embodiment Construction

[0028] In the following, as a non-limiting example, the signaling device is considered to be of the "signal light" type and as part of the rear lights of a vehicle, optionally of motor type. But the invention is not limited to this application. The lighting device may be of the DRL (daytime running light, abbreviation for "Daytime running Light (or Lamp)") type or of the "reversing light" type or of the "brake light" type, said DRL being used for assembly Automatically run (or light up) when a vehicle with this DRL moves forward.

[0029] figure 1 Schematically showing a cross-sectional view of an optical unit of a lighting and / or signaling device, the figure highlights the importance of gap-free assembly of an electronic circuit board for supporting a light source such as an LED.

[0030] The schematically shown optical unit 1 comprises a parabolic reflector 2 receiving an electronic circuit board 3 supporting an LED 4 held in a first housing 5 called the front housing , t...

Abstract

The invention relates to an assembly comprising a front housing (5), a rear housing (10) and an electronic circuit board (3) fixed between the front housing (5) and the rear housing (10), characterized in that the circuit board (3) is previously held on the front housing (5) by a snap member (8A, 8B) and has a determined gap. The circuit board (3) comprises at least one member (33) having a designdeformation, and the at least one member having the design deformation being integrally formed with the circuit board (3), and capable of holding the circuit board (3) inside the assembly by absorbing the determined gap (J) when the front housing (5) is secured to the rear housing (10).

Description

technical field [0001] The present invention relates to the assembly of an electronic circuit board in a housing, and more particularly to an assembly comprising a front housing, a rear housing and an electronic circuit board for fastening between the front housing and the electronic circuit board. between the rear case. [0002] Such a component may be a lighting and / or signaling device, such as a rear light of a motor vehicle. Background technique [0003] Here, "illumination and / or signaling device" is understood to be a device or device comprising a reflector configured to reflect light in a determined direction from a light source of the bulb type or from, for example, a light-emitting diode (or LED) multiple light sources. [0004] Usually, in lighting and / or signaling devices, when the electronic circuit board is integrated in the rear lamp, the electronic circuit board is fixed on the support by screwing, or assembled on the support by just snapping. [0005] When...
