Definitions
- the present invention relates to connectors, in particular multipole electrical connectors, used for example in the field of electrical wiring.
- the relevant connectors are used for / in areas requiring both reliability and flexibility, such as wearable-type applications, such as outfits or equipment of people operating in harsh environments (workers, service providers). rescue, soldiers and security forces, etc ...) or any other similar use.
- the use of a multipolar connector requires that the two main components of the connector (eg a component containing male contacts for example a plug and a component with female contacts, for example a socket) are connected to each other in a specific and predetermined angular orientation.
- This constraint can be achieved by particular shapes of the components allowing only a connection according to a predetermined relative position, or other equivalent technical means (such as asymmetrical constructions, interlocking elements, etc.).
- the connector described in this prior application comprises a base of substantially cylindrical shape and a plug connectable to the base removably or releasably, in which plug are arranged a plurality of contacts.
- the base comprises a disc-shaped conductive surface on or in which is disposed at least one conductive track forming at least one circular arc whose center substantially coincides with the center of the conductive face, said track being further disposed of in such a way as to mechanically couple with one of said plug contacts when the plug and the socket are connected.
- the center of the face of the base is a conductive disk, which is arranged to perform an electrical coupling with a contact of the plug disposed in the center of the latter .
- the connector described has a plurality of circular conductive tracks which are arranged concentrically. In general, the number of tracks is equal to the number of contacts but in execution modes, their number may be different.
- the present invention aims to make improvements to the known connectors, and in particular to the connector described in WO 2017/072620, particularly in terms of the sealing of said connector to allow its use in adverse environments (wet, dusty etc.) enter other.
- One embodiment of the present invention relates to a contact block 1 acting as a connector or can be reversibly integrated (removable) in a connector for transmitting any electrical signal through the connector.
- This block has a high seal and ensures the signal transmission function in adverse environments, for example with fluids (such as water) under pressure, dust, gel etc.
- the invention relates to a contact block for a connector, the block comprising at least one flexible membrane traversed by contacts, wherein said flexible membrane makes it possible to seal at the interface between said membrane and the contacts.
- the compression of the membrane ensures this sealing at the interface between said membrane and the contacts by the deformation of the membrane during compression.
- the electrical contacts have a degree of freedom allowing them both to exert a force on a connector part acting as a counterpart and positioned in front of the block as well as to present independence of movement between them.
- the counterpart can be the base of a connector for example.
- the contacts are for example of the type "piston contacts".
- the block is connected to a PCB or other equivalent means of connection.
- each block contact is mounted axially movable, preferably independently of the other contacts. In execution modes, the contacts are asymmetrically distributed or not.
- the invention relates to a plug or connector socket comprising at least one block as described in the present application.
- the plug can be bent or not.
- the invention relates to a connector comprising at least one block and / or a plug or base as described in the present application.
- the connector may include a socket on which the plug connects.

- the block comprises a plurality of contacts and the base comprises a plurality of conductive tracks.
- the tracks are preferably circular in shape and arranged concentrically.
- the number of tracks of the base is equal to the number of contacts of the form. In execution modes, their number may be different.
- the contacts may be on the base and the tracks on the form.
- the connector according to the invention comprises a locking system for blocking the rotation of the plug relative to the base and or to limit said rotation and / or block the disconnection of the plug on the base, for example below a certain threshold of traction force.
- the invention relates to an object comprising at least one base as described in the present application and combined with a plug and / or a block as described in the present application.
- the assembly forms an object connected by means of the connector formed by the base and the plug.
- the object is for example a "wearable" object such as a vest or a harness or another piece of clothing.

- Figure 2 illustrates a sectional view of a contact block according to one embodiment
- Figure 3 illustrates a perspective view of a contact block connected to a flexible PCB according to one embodiment
- Figure 4 illustrates a sectional view of a plug connected to a base according to one embodiment
- Fig. 5 illustrates a base according to an embodiment of the present invention
- Fig. 6 illustrates a connected plug and socket according to an embodiment of the present invention
- FIG. 7 illustrates an object comprising a connector according to an embodiment of the present invention
- Figure 8 illustrates an embodiment of a base with locking means.
- the connector according to the present invention is similar to that described in the application WO 2017/072620 in that it comprises a base and a plug, the plug connecting detachably to the base as set forth in this prior application, incorporated by reference in the present application.
- FIG. 1 firstly illustrates a subassembly 5 comprising a flexible membrane 4 in which electrical contacts 2 are mechanically assembled.
- the number of contacts 2 illustrated is an illustrative example and the subset may comprise at least one contact 2 or more contacts 2 (either less or more than the number shown in Figure 1).
- the electrical contacts 2 preferably have a degree of freedom allowing them both to exert a force on a counterpart positioned in front of the block 1 (for example a base 3) and to present an independence of movement between them to maintain optimal connection properties.
- These contacts 2 are thus mechanically assembled in a flexible membrane 4 so as to form an independent sub-assembly 5 "membrane-contacts" as illustrated in FIG. 1. They can be inserted into the membrane 4, or the membrane can be overmolded on the contacts 2, for example. In one embodiment, there may be a physico-chemical contact between the membrane 4 and the contacts 2 to create the seal.
- the subassembly 5 is then encapsulated in a container comprising two insulating parts 6, 7 (for example made of synthetic materials) exerting, once bonded together by any type of means (screwing, dips, interlocking). forced, bonding etc.), an axial force on the flexible membrane 4 which is created during encapsulation.
- This axial force compresses the membrane and results in a deformation of the flexible membrane 4 in a direction substantially perpendicular to that of said force (by this compression between the two parts 6,7) which makes it possible to ensure the seal between the contacts 2 and the flexible membrane 4, the membrane by its deformation conforming in a constrained manner to the external shape of the contacts 2.
- the flexible membrane 4 can be made by any type of medium (eg 3D printing, injection molding, overmoulding ...) and in all types of synthetic materials (such as elastomers) so as to withstand chemical agents, for example.
- the two insulating parts 6, 7 which may for example be made of thermoplastic or thermoset materials, high performance.
- the assembly thus formed 1 is designated "contact block”, see Figure 2.
- the seal between the two assembled insulating parts 6, 7 can be provided by an O-ring type seal 8 or other equivalent means (eg gluing), see FIG.
- the contact block 1 can be permanently or not connected to the external environment by connecting the contacts 2 to wires, a cable, a flexible or rigid PCB 9, see FIG. 3, or any other component to fulfill the desired function.
- Such a contact block 1 according to the invention has the advantage of constituting an independent subset usable in any type of connector or connection.
- the front face of the block 1 having a very advantageous geometry from this point of view, especially with regard to the mechanical robustness constituted by the insulating part 6 which makes it possible to protect the contacts.
- the contacts 2 may be of the "piston contact” type so that the contact block constitutes a set of sealed piston contacts, thereby solving even the problem of major sealing of this type of contact, namely the possibility of seizing because of penetration of particles or fluids.
- FIG. 4 illustrates the connection of a block 1 to a base 3.
- the base 3 and the plug 12 containing the block 1 may be of the type described in WO 2017/072620.
- FIG. 5 illustrates an example of such a base 3 seen from above, with circular and concentric tracks 11.
- FIG. 6 illustrates a plug 12 and a base 3 connected according to the principles of the present invention.
- the plug 12 comprises in particular a block 1 as described with reference to the preceding figures with its insulating parts 6 and 7 and the seal 8.
- the plug 12 also includes contacts 2 which are in contact with the tracks 11 of the base, according to the principles of WO 2017/072620.
- the invention is not limited to this configuration. It also covers connectors having at least one contact.
- the dimensions of the connector according to the invention can be arbitrary.
- the connector according to the invention has the particularity of not requiring prior orientation of the plug (eg a wired element) with respect to the base 3 (eg a device housing element, or on a product like a dress 13 or other).
- This advantage results from the cylindrical / circular geometry of the base and its conductive face (see eg Figure 1 of WD 2017/072620).
- the relative rotation between the base 3 and the plug 12 can be free or blocked by means of a suitable system, for example bi-stable type to cite a non-limiting example, for example a lock by lateral pressure and unlocking by axial pressure, a system of notches or an actuatable system manually.
- a block between the plug 12 and the base 3 can also be implemented to block the "unplugging" of the plug 12.
- An example is the so-called “push-pull” system. These means can also be implemented in a combined use, that is to say to limit or block the relative rotation, and in addition block the unplugging.
- FIG. 8 illustrates a base 3 with tracks 11 and an example of locking means between the base 3 and the plug 12.
- these means comprise housings 14 in which balls 15 of the plug 12 (see FIG. 6) can be housed to block or limit the relative rotation between the plug 12 and the base 3 and / or prevent unplugging (for example below a certain traction force).
- FIG. 7 illustrates an example of use of a connector according to the present invention: in this non-limiting example, the base 3 is fixed on a vest 13 and the plug 12 is ready to be connected to the base 3 for to arrive at the configuration of FIG. 6.
- the invention is of course not limited to the embodiments and examples described in the present application by way of illustration and non-limiting. Variations are possible in the context of the protection conferred and claimed, in particular by using equivalent means.
- the execution modes can also be combined with one another and technical characteristics of one of the modes can be used in another mode.
- the construction of the plug and the base is reversed: that is to say that the contacts 2 can be on the base 3 and the tracks 11 on the plug 12.
- the construction described in the present application but reversed, namely that elements of the plug 12 (in particular illustrated in Figures 1 to 4) are placed on / in the base 3 and elements of the 3 base (including tracks 33, housing 14, Figure 7) are placed on / in the form 12.
- the top portion may belong to the 'base and the bottom part to the plug.
