Problems solved by technology

The first disadvantage of fastening in this way is little mechanical strength, since it is difficult to grip the solder onto the threaded part, thus limiting the tightening torque that can be applied to the bolt that penetrates the threaded hole
A second disadvantage of this type of fastening is the poor reproducibility in terms of the mechanical strength of the fastening, which means that it is impossible to define a single tightening torque for all spacers, making automatic assembly difficult

Embodiment Construction

[0019] refer to figure 2 , the spacer 101 for welding of the present invention includes an elongated body with a hexagonal cross-section and a centering post 103 with a substantially cylindrical shape. The elongated body 102 has a threaded end 104 and an opposite end 105 provided with a transverse bearing surface 106 and with a centering post 103 projecting therefrom along the axis of the elongated body 102 . The centering post 103 is connected to a lateral bearing surface 106 via a circular groove 107 . The centering column 103 is provided with two longitudinally extending, symmetrically arranged outer flats 108 .

[0020] refer to image 3 and Figure 4 , the spacer 101 for soldering of the present invention is used in this example to assemble the first electronic card 110 and the second electronic card 111 of the electronic module 112 together. The elongated body 102 of the spacer 101 for welding is installed between the inner surface 113 of the first card 110 and the i...

Abstract

The invention concerns a solder spacer comprising an elongate body (102) having one end provided with a tapped hole (104) and an opposite end provided with a transverse support surface (106) from which a smooth centring pin (103) extends protruding, the pin (103) comprising a longitudinal outer passage (108) extending over a least a portion of the length of same to the transverse support surface (106), allowing a molten soldering paste to rise by capillarity to the transverse support surface (106). The invention also concerns a module (112) comprising such a spacer.

Description

[0001] The invention relates to a soldered spacer for assembling together two electronic cards or two boards of any type. The invention also relates to an electronic module comprising such a spacer. Background technique [0002] In an electronic module comprising a plurality of electronic cards, spacers are often used to assemble the individual electronic cards together. Such spacers are either made of plastic material, or they are made of metal material, wherein the metal spacers also serve to provide an electrical connection between the electrical grounds of the electronic card. [0003] Certain spacers (also referred to as "spacer posts") include an elongated body having a tapped end defining a threaded bore and a threaded segment extending from the other end of the elongated body. [0004] FIG. 1 shows a first electronic card 1 and a second electronic card 2 of an electronic module 3 assembled together by means of at least prior art spacers or standoffs 4 . [0005] The ...
