Definitions
- Multicontact block having at least two electrical contacts
- the invention relates to a multicontact block comprising at least two independent electrical contacts of the blistering type, elastically deformable between a rest position and an active end position.
- buttons are to provide electrical activation by means of a switch soldered on the printed circuit.
- this solution is expensive.
- a third solution consists in using blistering elements which presently consist of elastic metal contacts resiliently deformable between a rest position in which the said contacts have the concave curved overall shape of a dome, and an active extreme position in these contacts are deformed so as to have a local reversal with respect to the initial dome shape.
- the present invention also aims at providing contacts of the blistering type, and its main purpose is to provide contacts, on the one hand, whose production cost is reduced compared to that of current contacts of this type, and 'somewhere else, whose attachment in an electronic box is facilitated and allows to meet with a great repetitiveness, the qualification specifications.
- this multicontact block comprises:
- Such a multi-contact block therefore comprises, in one piece, a rigid frame formed of stiffening posts and crosspieces, and a plurality of contacts connected to the uprights of said frame by means of elastic means able to allow free deformation. such contacts.
- this multicontact block comprises bearing pads defining a reference plane and for securing correctly and quickly said multicontact block, for example by soldering on a printed circuit, ensuring subsequent unit deformability of the different contacts, controlled by the presence of sleepers ..
- the concept of the invention therefore leads to a significant economic gain in the production costs of the contacts, in particular by making several contacts on one and the same part, and a significant gain in terms of mounting contacts, because a single operation, moreover automatable and repetitive, is required for the simultaneous fixing of several contacts.
- the multicontact block according to the invention is formed of a perforated metal plate made by cutting, in particular by means of a tool to follow.
- the support pads advantageously consist of tabs generally shaped angle obtained, each by cutting in a profile and folding.
- each amount has a section L-shaped formed of a so-called horizontal wing junction contacts, and a so-called vertical wing extending above the plane defined by the horizontal wings.
- the frame advantageously comprises at least two sleepers in which, in addition, are advantageously positioned the support pads.
- the multicontact block comprises at least three contacts
- the latter advantageously comprises crossbars interposed between each pair of contacts, which guarantee, in addition to the transverse rigidity of the framework, obtaining an identical flexibility for all the contacts. contacts, except possibly the two contacts located at both longitudinal ends of the frame, which have slightly greater flexibility.
- each contact advantageously has, seen in plan, the general shape of a rectangular patch connected to the uprights by elastic strips extending from two opposite peaks of said contact.
- each elastic blade advantageously has the general shape of an S attached to an upright and to one of the tops of a contact, so as to be centered on the diagonal of said contact extending between the two connecting vertices. the latter with the amounts.
- the multicontact block comprises longitudinal fins extending on the underside of the uprights, centering said block on a support member such as a printed circuit.
- centering fins are adapted to be positioned in notches in the printed circuit before welding, facilitating the positioning of the multicontact block.
- FIG. 1 is a perspective view, seen from above, of a multicontact block according to the invention
- FIG. 2 is a perspective view, viewed from below, of this multicontact block
- FIG. 3 is a cross-section, on an enlarged scale, of this multicontact block positioned on a printed circuit.
- the object of the invention shown by way of example in the figures consists of a multicontact block comprising five independent electric contacts 2-6 of the blistering type, consisting of a generally rectangular patch arranged so as to be deformable from elastically between a rest position in which it has a generally concave curved shape and an active end position in which it is locally returned from its initial rest position.
- This multicontact block of generally rectangular shape, is advantageously made by cutting, by means of a tool to follow, a plate made of an electrically conductive material with a high modulus of elasticity, such as stainless steel 1.
- This cut is adapted to conform the initial plate 1 into a final block having, firstly, laterally, two longitudinal edges 1 1, 12 forming uprights having an L-shaped section formed of a so-called horizontal wing to which are connected the contacts 2-6, and a so-called vertical wing extending above the plane defined by the horizontal wings.
- the initial plate 1 is also shaped so as to comprise four crosspieces 7-10 extending between the horizontal flanges of the uprights 1 1, 12, in the same plane as the said horizontal flanges, said crosspieces being interposed each between two contacts 2 -3, 3-4, 4-5, and 5-6, equidistant from each of said two contacts.
- two of these sleepers in the example the two end crosspieces 7 and 10, that is to say each of the sleepers closest to one of the longitudinal ends of the block, have at each of their end longitudinal, a cutout delimiting, after folding, a bearing pad consisting of a tab in the general shape of angle, respectively tabs 13-14 for the crossbar 7 and tabs 15-16 for the crossbar 10, all of said pads d support defining a reference plan for supporting the multicontact block.
- the multicontact block also comprises longitudinal fins 17-20 extending on the underside of the uprights 11, 12 for centering said block on a printed circuit.
- these fins 17-20 are four in number arranged each under the face of the horizontal flange of the uprights 11, 12, at each end of each of said amounts.
- such fins 17-20 are adapted to be housed in notches such as 24 formed in a printed circuit 23, in a position of the multicontact block in which the latter rests via the pads. 13-16 on said circuit board.
- each of the five contacts 2-6 is positioned midway between the two uprights 1 1, 12, and the rectangular pellet forming each of said contacts is connected to said amounts by elastic strips 21, 22 extending from two opposite peaks of said pellet.
- each of these resilient blades 21, 22 has the general shape of an S attached to the horizontal flange of an upright 11, 12 and to one of the apices of a contact 2-6, so as to be focused on the diagonal of said contact extending between the two connecting peaks of the latter with the amounts.
- Such elastic blades 21, 22 are designed so that, when the multicontact block rests on a printed circuit 23 by its support pads 13-16, each contact 2-6 has an active position in which the said contact is at contact of an electrically conductive zone 25 of a printed circuit 23.
- Such a multi-contact block therefore comprises, in one piece, a plurality of contacts 2-6 connected to a frame 7-12 by means of elastic means 21, 22 able to allow free deformation independent of said contacts.
- this multicontact block comprises support pads 13-16 defining a reference system for correctly and quickly securing said multicontact block, for example by soldering, on a printed circuit 23, guaranteeing a subsequent unit deformability of each of the contacts 2-6.
