Abstract
Description
- The present invention relates to a positioning and locking method and to a positioning and locking device for an input/output connector.
- The invention relates particularly to a positioning and locking method and to a positioning and locking device for an input/output connector used in a mobile telephone, the said device being fixed in the housing of the connector which is intended to be surface-mounted, for example on a printed-circuit board.
- In this type of construction, it is necessary for all the contacts of the connector to be able to ensure a contact pressure sufficient for electrical transmission during the operation of the product, the surface-mounting of the connector and throughout the life of the device on which it is mounted, this being so sometimes under harsh handling conditions.
- Thus, it has been found that, in order for this function to be effective, the bearing plane of the contacts of the connector must be coincident or at least almost coincident with the plane of the printed-circuit board (PCB). In fact, this coplanarity allows a so-called coplanarity requirement, necessary for implementation of the surface-mounting process, to be effectively met, which requirement means that any one of the contacts must lie within a maximum tolerance range relative to the bearing plane of the contacts of the connector on the printed circuit, this bearing plane thus defining the reference plane for the coplanarity.
- Another constraint on the surface-mounting process comes from the fact that this tolerance range must be as small as possible. Furthermore, the dimensional constraints of the product, when printed-circuit boards intended for equipping miniaturized electronic devices such as portable telephones are involved, do not allow the contacts of the connector to be guided sufficiently accurately. As a result of the constraints described above, the bearing plane cannot be defined precisely and reproducibly, which leads to significant dispersion with regard to the coplanarity.
- The object of the invention is to alleviate the drawbacks of the prior art that are described above.
- According to the invention, to solve this coplanarity problem, a positioning device having a projecting part which is intended to rest on the plane of the printed circuit is forcibly inserted into a first slot and into a second slot, these slots lying on either side of the housing of the connector.
- By virtue of this technique, the positioning devices position themselves relative to the known reference plane consisting of the surface on which these devices rest in their respective slots. The bearing plane of the pins of the connector is thus accurately and reproducibly defined.
- Further features and advantages of the invention will emerge from the description which follows, given by way of non-limiting examples, with reference to the appended figures in which:
- Figure 1 shows a perspective view of the front face of a connector equipped with a positioning and locking device according to the invention;
- Figure 2 shows a perspective view of the rear face of the connector in Figure 1;
- Figures 3 and 4 show a plan view of the front face and of the rear face, respectively, of the connector in Figure 1;
- Figure 5 shows, diagrammatically and in partial cross section, a top plan view of the connector in Figure 1;
- Figure 6 shows diagrammatically a second embodiment of the invention.
- Figures 1 and 2 show an input/
output connector 2 for a mobile telephone, intended to be surface-mounted on a printed-circuit board 6 shown partially in Figure 5. The saidconnector 2 hascontacts 8 intended for making an electrical connection with the printedcircuit 6. - In order to ensure quasi-coplanarity of the bearing plane of the
contacts 8 with the plane of the printed-circuit board 6, apositioning device 12 having a projectingpart 16 which is intended to rest on and be soldered to the plane of the printedcircuit 6 is forcibly inserted into afirst slot 10 and into asecond slot 11, these slots lying on either side of thehousing 4 of theconnector 2. - The projecting
part 16 may have either a flat shape, as may be seen in Figure 5, or the shape of a sinusoidal having at least twolobes - Furthermore, the positioning device includes a locking means 26 which makes it possible for a plug to be fixed to the
connector 2. - Thus, pulling on the plug does not affect the soldered joints insofar as the plug is essentially supported by the positioning and locking device.
- In this way, the device according to the invention, because of its design, allows two functions - positioning and locking - to be carried out, which functions are normally fulfilled independently by two independent devices.
- As may be seen in Figure 6, illustrating the second embodiment of the invention, the projecting
parts 16 has the shape of a sinusoid having twolobes lobes circuit board 6 which forms the reference plane for positioning the connector. - The device according to the invention is reversible so that, by turning it through an angle of 180°, it is possible to insert it just as well in the
left side slot 10 as in theright side slot 11. This makes it possible to simplify the mass production of the positioning and locking device, in order to meet the growth in the use of increasingly miniaturized portable telephones. - Furthermore, because of their sinusoidal shape, the
lobes - Of course, the device according to the invention is not limited to this application and can be used with any smart-card reader connector having contacts intended to be surface-mounted on a printed-circuit board and in which quasi-coplanarity of the bearing plane of the said contacts with the plane of the printed-circuit board is necessary.
