Problems solved by technology
However, the connectors, usually comprising plastic material, must be fixed to the support during additional manual or automatic soldering of the connecting pins to the board, which increases the manufacturing costs of the board
[0009] Also, the flatness of the solder that connects the pins to the board may be defective
The presence of these flatness defects can lead to a bad connection, more precisely, to a failure to braze one of the connection pins, and can cause redo operations that further add to the manufacturing time and cost of the board

Embodiment Construction
[0038] In these figures, substantially the same elements have the same reference numerals.
[0039] figure 1 A printed circuit board (PCB) or integrated circuit card (IC card) 1 is shown in a simplified manner that is easier to understand, having a first or front face 1 a and a second or rear face 1 b opposite to each other.
[0040] For example, the board 1 carries surface mount components (CMS) 3 on its first or front face 1 a, and at least one electrical component 5 (such as a transistor) and electrical conductors 7 on its second or rear face 1 b, Said electrical conductors 7 are connected to the wiring harness of the vehicle for the control of electrical means, such as the electrical heating means described hereinafter, which are connected to the second face 1b of the panel 1 and are thus in a panel position with the second face 1b. on the same side. Components 5 and 7 are reflow soldered to the board in the described embodiment.
[0041] Furthermore, the board 1 compri...

The invention relates to an electrical connector for electric circuit board (1), said connector including: a socket (13) that is made of an electrically insulating material and intended to be mounted into an opening (9), corresponding to said board (1), while projecting relative to a front surface of said board (1); and at least one electrical connection pin (15). According to the invention, said at least one electrical connection pin (15) has a substantially U-shaped general form with a first side arm (15a), leading into the socket (13), and a second side arm (15c) for connection via configured reflow in order to pass, when mounted, through said board (1) so as to lead onto the front surface of said board (1). The invention is characterized in that said material of the socket (13) is a plastic material that is configured so as to resist reflow temperatures. The invention also relates to an electric circuit board having one such connector and to an electric heating device comprising one such board.
Description
technical field [0001] This invention relates to circuit board connectors. The invention applies more particularly to a circuit board of an electric heating device for a motor vehicle. Background technique [0002] Such electric heating devices, also known as electric radiators, are usually installed in ducts for the circulation of the air to be heated downstream of the heat exchanger for the flow of air and liquid passing through the heat exchanger (usually engine coolant) to heat the air used to heat the passenger compartment of a motor vehicle, and to defog and de-ice. [0003] The electric heating means comprises a heater module arranged to be directly exposed to the air passing through the heating means so as to provide virtually immediate heat replenishment if the heating by the heat exchanger is insufficient. [0004] The electric heating device is temporarily operated until the heat exchanger can heat the air itself in the desired manner. [0005] The heating unit...
