Embodiment Construction

[0031] figure 1 The radio frequency transmitter is shown in cross section.

[0032] The radio frequency transmitter 1 comprises an enclosure formed by two half shells or covers 61 , 62 . These covers are made of plastic material. Inside the transmitter there is at least one printed circuit 5 (see figure 2 ).

[0033] According to one embodiment of the present invention, the transmitter 1 may comprise a spacer 4 (in figure 2 and image 3 ), said gasket 4 will make it possible to keep the housing tight and protect the printed circuit 5 . The transmitter 1 may also include components such as light emitting diodes or lamps. The function of the gasket 4 is thus to guarantee the sealing tightness of parts of the housing in order to protect all components.

[0034] (as in figure 2 and image 3 The two covers 61 , 62 illustrated in ) are linked together at the outer edges of these covers by the metal or metallized part 3 . In other words, the covers 61 , 62 are arranged o...

Abstract

The present invention relates to radio frequency transmitters with metal / plastic heterogeneous structures. The invention relates to a radio frequency transmitter (1) comprising two plastic covers (61, 62) arranged one above the other surrounding a printed circuit (5), and Having a metal strip (3) inserted between the covers in the joint area of ​​the covers, characterized in that the inner part of the metal strip (3) is fastened to the metal strip (3) created between the two plastic covers (61, 62) at least one groove (212) between. The invention also relates to a method for assembling a radio frequency transmitter (1), said method comprising the step of assembling the different parts forming the transmitter (1).

Description

technical field [0001] The present invention relates to the field of radio frequency transmitters, and more particularly to a radio frequency transmitter having a metal / plastic heterogeneous structure. Background technique [0002] The radio frequency transmitters addressed by the present invention are for example of the type used with motor vehicle keys to remotely control the opening or closing of the doors of the motor vehicle or even to start the motor vehicle. [0003] In fact it is common for a key of a motor vehicle to be associated with a remote control device housed in the head of the key, usually in the form of a housing, or in an associated key fob. Together with the constraints of the compactness of these devices, there are external attacks associated with sometimes difficult testing and usage situations, and for example there are bumps, drops, contact with water, tension on key fob attachment rings, electrostatic discharge, which means that these devices have t...
