Definitions
- the invention relates to a method for separating a connector from an electronic card. It relates more particularly to a connector with pins inserted by force into holes in electronic cards.
- Electronic cards generally perform a multiplicity of functions using a large number of components. They are, most often, carried out automatically. It is common today to use connectors whose rods or pins are forcibly insertable into corresponding holes in the card. Compared to a solder connection, this technique has the advantage of allowing faster manufacturing; moreover, it is less polluting than welding.
- each spike has a pointed end extended by a widened part in the central part of which is provided a light or a weakening so that this part of larger section can decrease in width when the spike is introduced to force into a hole in a card.
- the enlarged part has, before the introduction, a slightly larger section than the section of the hole; thus, when the initially enlarged part is retained in the hole, it exerts pressure against the edge. This pressure ensures contact with the conductive edges of the hole and, moreover, allows gas tightness between the two faces of the card.
- the connector If the connector is defective or if its pins are incorrectly inserted, it must be possible to remove it without damaging the card. Indeed, after insertion, the card has a high value, and it is therefore preferable not to discard it.
- the method according to the invention consists in exerting an extraction force simultaneously on all the pins of the connector. To this end, either press on all the ends of the pins protruding from one side of the card, or pull on the connector body. The forces being distributed over the pins and being exerted at the same time on the pins, the risks of damage to the card are minimized.
- a first part having a pressure surface against the ends of the pins and means for holding the card during the pressure exerted on the ends of the pins .
- the holding means consist of an end surface of a second part installed, relative to the card, opposite the first part and which comprises a housing receiving the connector to be extracted.
- the housing is produced in a room independent of the holding means.
- This extraction device can use a conventional press comprising, at the bottom (or top), an anvil and, at the top (or bottom), a pressing device.
- the first part which has the pressure surface against the ends of the pins, is secured to the anvil and the second part or the guide means are secured to the pressing tool.
- the card can be fixed on a mobile table.
- the anvil and the pressing device move simultaneously so that the pressing surface comes into contact against the ends of the pins when the pressing device holds the card.
- the device comprises a clamping means of the connector body and a means for pulling this connector body in the direction of extraction.
- These means for exerting the extraction force include preferably carry a screw means transforming the torque of the screw into a translational force.
- the means for holding the body of the connector comprises, for example, means for attaching complementary cells, or hollow, to this body.
- the invention provides a method for separating a connector from an electronic card, the pins of the connector being forced into corresponding holes in the card. This process is characterized in that an extraction force is distributed distributed over all the pins inserted by force.
- pressure is exerted on the ends of the pins.
- the tensile force is exerted on the body of the connector opposite the pins.
- the present invention further provides a device for implementing the first embodiment of the method which comprises a first part with a pressure surface against the ends of the pins of the connector to be extracted and means for holding the card.
- this device comprises, on the side of the card opposite to the first part, a housing or recess for receiving the connector to be extracted.
- the housing constitutes a recess of a part, the end surface of which, into which the recess opens, constitutes a bearing surface against the card to hold it.
- the connector to be extracted having visible rods in extension of the pins, the housing is separated into guide compartments of each of the rods.
- the pressure surface has one or more grooves for positioning the ends of the pins.
- each pin of the connector being extended by an apparent rod, it comprises, on the side of the card opposite to the first part, means for guiding the rods during extraction.
- the parts of the device on either side of the card have an extension in the plane of the card which is little different from the extension of the connector.
- the guide means have a comb, the teeth of which are inserted between the rods or rows of rods.
- the teeth of the comb have an inclined outer edge so that the presence of the teeth of the comb does not affect accessibility to the surface of the card in the vicinity of the connector to be extracted.
- a device for implementing the second embodiment of the method comprises means for holding the body of the connector opposite the pins to be extracted from the holes in the card and means for exerting traction on the holding means .
- the traction means are of the screw type.
- the holding means comprises protrusions or teeth fitting into hollows or cells of the body of the connector.
