Description

Electrical connection socket comprising a movable connection element, complementary base for electrical connection, and an assembly comprising such bases

FIELD OF THE INVENTION

The invention relates to an electrical connection base, a complementary base of electrical connection and an assembly comprising an electrical connection base and a complementary base of electrical connection. The invention relates in particular to the end contact pads, but not only. For example, the electrical connection base is a socket base while the complementary electrical connection base is a connector socket, or vice versa.

STATE OF THE PRIOR ART

[0002] Generally, the socket and current connector bases, in particular for electric power currents, are designed to prevent the formation of electric arcs and to cut them as quickly as possible. For example FR 2 466 111 or FR 2 623 945 disclose end contact bases comprising a spring system for separating as soon as possible the socket base and the connector base during disconnection.

Such known systems give complete satisfaction when disconnecting. However, in some cases arcing can occur at the connection. Furthermore, the springs for separating the socket base and the connector base during the disconnection require when the connection of the connector base and the socket base to produce a significant effort to compress these springs. There is therefore a need in this sense.

PRESENTATION OF THE INVENTION

The present disclosure relates to an electrical connection base.

An embodiment relates to an electrical connection base extending in an axial direction and comprising a movable element in the axial direction between a contact position and an isolated position, in which the movable element is configured to come into operation. contact with at least one complementary contact of a complementary base of electrical connection in contact position while the movable element is configured to be remote from the at least one complementary contact of the complementary electrical connection base in isolated position, the electrical connection base comprising a displacement mechanism configured to move the movable element between the contact position and the isolated position when the electrical connection base and the complementary electrical connection base are engaged and rotated relative to each other about the axial direction.

Subsequently, and unless otherwise indicated, by "complementary contact" means "the at least one additional contact".

It is understood that the electrical connection base may be a socket base or a connector base, while the additional base of electrical connection may be a connector base or a socket base, respectively.

It is recalled that a socket base forms a female part that can belong to a power outlet (where the socket is generally integral with a wall, a housing, or the like), an extension, or a connector (where the socket is usually part of a socket) while a connector socket forms a male part that may belong to a power outlet (or the connector socket is usually part of the plug ), an extension, or a connector (where the connector base is generally secured to a device or the like).

It is also recalled that in general, a socket comprises a socket base and a handle or rollover integral with said socket base; a plug comprises a connector socket and a handle or cowling secured to said connector socket; an extender is an assembly comprising a plug and a plug; an outlet is an assembly comprising a socket base and a plug; a connector is an assembly comprising a plug and a connector socket.

Of course, the handle or cowling can be integrated (e) socket base or the connector base, in which case said socket base or connector base also forms a plug or plug. For example, the electrical connection base (and thus the complementary base of electrical connection) is "end" contact (s).

A contact of the "end" type is a contact where the electrical connection with a complementary contact, for example a pin, is provided by a contact face substantially perpendicular to the axial direction. Such a contact is configured to cooperate in abutment with a complementary face, for example a distal end face of a pin, the contact between these two faces being generally made with a certain pressure to guarantee the passage of current of a contact. to the other.

It is understood that in the contact position the movable member is in position to be in contact with a complementary contact of the complementary base of electrical connection, so that the electric current can flow between the complementary contact and the movable member. . Conversely, it is understood that in isolated position, the movable element is in position to be remote in the axial direction of the complementary contact of the complementary base of electrical connection, so that the electric current can not flow between the complementary contact and the movable element (ie the complementary contact and the movable element are electrically insulated from each other in the isolated position).

Of course, the movable member may comprise a plurality of separate portions electrically insulated from each other, each portion being configured to be in electrical contact with a complementary complementary contact of a complementary base of electrical connection. It is understood that each portion is respectively in contact, at least in the contact position, with a conductive element connecting the movable element to a corresponding wire clamp of the electrical connection base. Thus, the movable element may be in permanent contact with the one or more clamps, or is in contact with the one or more clamps only in the position of contact.

The displacement mechanism moves the movable member in the axial direction, particularly from the isolated position to the contact position and vice versa. It is understood that this movement mechanism is actuated when the base electrical connection and the complementary base of electrical connection are engaged (ie cooperate together), and that one is rotated relative to the other. By actuating this mechanism, the moving element is moved from the isolated position to the contact position, and vice versa. Of course, the displacement mechanism is configured to cooperate with an actuator of the complementary base of electrical connection, said actuator being configured to actuate the movement mechanism.

Thanks to the axial displacement of the movable member and the movement mechanism, it perfectly control the connection and disconnection between the plate (and therefore the active parts of the electrical connection base - ie parts under electrical voltage), and the complementary contact (s) of the complementary base of electrical connection. Thus, the electric arc formation is controlled and therefore avoided or, at least, limited, both during the connection and during disconnection. Moreover, unlike the devices of the state of the art, to engage the electrical connection base and the complementary base of electrical connection it is not necessary to provide a significant effort. Indeed, in the devices of the state of the art when engaging the bases, which is concomitant with the electrical connection of the contacts, it is necessary to provide a significant effort to compress a spring system for separating the fastest possible both pedestals when disconnecting.

In certain embodiments, the displacement mechanism comprises an axially extending shaft rotatably mounted about the axial direction on a base, the shaft comprising one of a helical ramp and a lug, the element mobile having the other element among the helical ramp and the lug, the lug cooperating with the helical ramp.

It is therefore understood that the electrical connection base comprises a base and a shaft extending in the axial direction, the shaft being mounted on the base by a pivot connection. It is also understood that the shaft has at least a first axial wall, this first axial wall having for example a cylindrical shape or an angular portion of a cylinder shape. Similarly, it is understood that the movable element has at least a second wall axial, this second axial wall having for example a cylindrical shape or an angular portion of a cylinder shape. The first and second axial walls are arranged at least partly facing each other.

Thus, according to a first variant, the first axial wall of the shaft has a helical ramp while the second axial wall of the movable member has a lug. According to a second variant, the first axial wall of the shaft has a lug while the second axial wall of the movable element has a helical ramp. For example, the helical ramp is formed by a wall of a helical groove formed in the first or second axial wall. In another example, the helical ramp is formed by a helical shoulder formed on the first or the second axial wall. This helical ramp is configured to cooperate in axial support with the lug, whereby an axial translation movement is impulsed to the movable element during the rotation of the shaft about the axial direction. Of course, the movable member is locked in rotation about the axial direction, whereby it can not be rotated by the shaft but only in translation in the axial direction.

A displacement mechanism having such a helical ramp structure is simple, robust and efficient, and allows a very good control of the axial displacement of the movable member, and thus electric arcs. Such a helical ramp mechanism also allows to reduce the forces for the passage of the movable element between the isolated position and the contact position, and vice versa, which makes its manipulation by a user easier.

For example, the tree is a central tree, but not necessarily. A central shaft further simplifies the structure of the moving mechanism, which makes the control of electric arcs even more reliable.

In some embodiments, the shaft is configured to cooperate by complementarity of form with a complementary element of the complementary base of electrical connection and to be rotated about the axial direction by the complementary element of the complementary base of electrical connection.

It is therefore understood that when the electrical connection base and the complementary base of electrical connection are engaged, the shaft cooperates, for example by fitting, with the complementary element, comprising for example a rod. For example, the tree is hollow and receives the stem, or vice versa. For example, the shaft and the shaft are central, the shaft and the shaft having complementary reliefs so that they are coupled in rotation about the axial direction when they are fitted with each other in the axial direction. In another example, the rod is eccentric and has no rotation coupling relief with the shaft so that a fitting of the rod with the shaft can couple them in rotation. Thus, the relative rotation of the electrical connection base and the complementary base of electrical connection around the axial direction allows the complementary element to drive the shaft in rotation about the axial direction, and thus to actuate the mechanism of displacement to axially move the movable member. Such a structure for actuating the displacement mechanism is simple, robust and efficient, and allows a very good control of the axial displacement of the movable element, and thus electric arcs.

In some embodiments, the movement mechanism includes a polarizer.

It will of course be understood that such a polarizer is configured to cooperate with a complementary polarizer of the complementary base of electrical connection. For example, the shaft has a flat or dissymmetrical shape revolution allowing, considered in the azimuthal direction, a single position of cooperation by complementary form with the complementary element. In the case where the movable element is configured to contact a plurality of complementary contacts separate from a complementary electrical connection base, this makes it possible to ensure that the movement mechanism can be actuated only if the relative position of the electrical connection base and the complementary base of electrical connection is such that the complementary contacts will be in contact with the corresponding portions of the mobile element. In other words, this ensures that in the contact position each phase of the electrical connection base will be well contacted with the corresponding phase of the complementary electrical connection base. Moreover, by providing different polarizers according to the models of connection bases electrical, this avoids contacting an electrical connection base with a complementary electrical connection base of polarity, voltage / voltage, frequency or amperage / different intensity. This makes it possible to improve safety and to avoid, at least to limit, the formation of particularly damaging electric arcs.

In some embodiments, the electrical connection base comprises a holding device in position of the movable member.

It is therefore understood that the holding device keeps, without necessarily locking, the movable element in the isolated position or in the contact position. This ensures that the movable element is moved axially between these two positions only if the movement mechanism is actuated voluntarily. Such a device makes it possible to avoid, at least to limit, possible inadvertent displacements of the movable element, and therefore the loss of electrical contact (in the contact position) or the formation of any electric arcs (in position isolated).

In some embodiments, the device for holding the movable member in position comprises a cam carried by the shaft, and a pressing member cooperating with the cam.

It is understood that the pressing member exerts pressure on the cam so as to maintain it in a predefined position. Thus, the pressure element exerts pressure on the cam to maintain it in a first position corresponding to the isolated position of the movable element and / or to maintain it in a second position corresponding to the contact position of the movable element . Such a structure of the holding device comprises a cam and a pressing element is a simple structure, robust and efficient, which allows a very good control of the maintenance of the movable element in isolated position or in contact position in a stable, reliable and This allows the control of arcs.

In some embodiments, the electrical connection base has a first stable configuration in which the movable element is in the contact position, a second stable configuration in which the movable element is in an isolated position, and a plurality of unstable intermediate configurations between the first configuration and the second configuration in which the electrical connection base tends to come in the first configuration or in the second configuration.

It is of course understood that a stable configuration is a more stable configuration than unstable configurations, and that conversely, unstable configurations are less stable configurations than stable configurations. In other words, it is understood that the stable configurations are configurations taken by default by the electrical connection base, while the unstable configurations are transient configurations and can not be taken by default by the electrical connection base.

This ensures that all the intermediate positions of the movable element between the breaking position and the contact position correspond to unstable configurations of the electrical connection base. Thus, for example, if the electrical connection base were to undergo an involuntary operation resulting in actuating the movement mechanism, leaving it in an intermediate configuration, and therefore unstable, it is ensured that the electrical connection base will resume automatically the first or second configuration. In another example, if a user only partially actuated the movement mechanism, leaving the electrical connection base in an intermediate configuration, and therefore unstable, it is ensured that the electrical connection base would automatically take the first or the second configuration. This makes it possible to avoid, at least to limit, the formation of electric arcs.

In some embodiments, the movable element comprises a plurality of contacts configured to contact the at least one complementary contact of the complementary base of electrical connection, the relative angular travel between the electrical connection base and the complementary connection base electric to move the movable element between the isolated position and the contact position being less than the minimum angle separating two adjacent contacts.

It is understood that each contact is configured to contact a separate complementary contact. For example, there are as many contacts as there are complementary contacts, but not necessarily. It is also understood that at least two contacts are distributed azimutally around the axial direction. For example, all contacts are azimutally distributed around the axial direction. In another example, the contacts are regularly distributed in the azimuth direction (ie the angle between two adjacent contacts is identical for all contacts).

In general, it is understood that the azimuthal direction is a direction describing a ring around the axial direction. This direction therefore corresponds to the direction of relative rotation of the electrical connection base with respect to the additional electrical connection base for axially moving the movable element.

It is also understood that the angle necessary to turn the electrical connection base relative to the additional electrical connection base to actuate the movement mechanism and bring the movable element from the isolated position to the contact position, and conversely, is less than the minimum angle separating two adjacent contacts (in the azimuthal direction, around the axial direction). The angles are of course measured around the axial direction, in a plane perpendicular to the axial direction (i.e. in the relative rotation plane of the two bases).

With such a configuration, it is ensured that, during the relative rotational movement between the electrical connection base and the additional electrical connection base to move axially the movable element, there is no risk that a contact is found close to or opposite a complementary contact which does not correspond to it (ie with which the contact is not intended to come into contact). There is therefore no risk that in the contact position, a contact of the electrical connection base contacts a complementary contact complementary electrical connection base that does not correspond. This makes it possible to avoid the formation of unwanted electric arcs between distinct phases of the socket base and of the connector base and to secure the connection of the phases of the electrical connection base and the complementary electrical connection base.

In some embodiments, the movable element comprises at least one contact configured to contact the at least one complementary contact of the complementary base of electrical connection, and the electrical connection base comprising a safety disc. movable in rotation between a protective position preventing access to said at least one contact and a connection position allowing access to said at least one contact.

It is understood that the safety disk is rotatable about the axial direction. Such a disk makes it possible to block access to the (x) contact (s). This improves security by blocking access to the active parts of the electrical connection base. This also avoids the inadvertent formation of electric arcs when approaching the electrical connection base and the additional electrical connection base, in particular to engage them. According to a variant, the security disk is carried by the additional electrical connection base and allows or prevents access to the complementary contact.

In some embodiments, the safety disk is rotatably coupled with the shaft.

Thus, when the shaft of the displacement mechanism is rotated, the safety disk is also rotated. This makes it possible to synchronize the movement of the movable element and the safety disc, which increases safety and reduces the risk of unwanted arcing.

In some embodiments, the electrical connection base comprises at least two distinct position indicators configured to indicate the relative azimuthal position of the electrical connection base with respect to the complementary base of electrical connection.

For example, such indicators are used in combination, when the electrical connection base is engaged with a complementary base of electrical connection, with an index. This allows the user to perfectly know the relative azimuthal position of the electrical connection base with respect to the complementary base of electrical connection, and therefore the associated position of the mobile element and, consequently, the connected state or not contacts of the electrical connection base with the complementary contacts of the complementary base of electrical connection. The user can thus avoid any false manipulation. This increases safety and decreases the risk of unwanted arcing. The present disclosure also relates to a complementary base of electrical connection.

An embodiment relates to a complementary electrical connection base extending in an axial direction and comprising an actuator configured to actuate a moving mechanism of a movable element of an electrical connection base when the complementary connection base electrical and electrical connection base are engaged and rotated relative to each other about the axial direction. Of course, the movable element of the electrical connection base is movable in the axial direction between a contact position and an isolated position, and configured to make electrical contact with at least one complementary contact of the complementary electrical connection base in position of contact while the movable member is configured to be remote from the at least one complementary contact of the complementary electrical connection base in isolated position.

It is therefore understood that such a complementary base of electrical connection is complementary to the electrical connection base object of the present disclosure and that the actuator allows to actuate the movement mechanism of the electrical connection base to pass the element. moving from the contact position to the isolated position, and vice versa. Thus, when the actuator cooperates with the moving mechanism, it is considered that the electrical connection base and the complementary electrical connection base are engaged. The relative rotation of the electrical connection base with respect to the complementary base of electrical connection around the axial direction thus makes it possible to actuate the movement mechanism and thus to move the movable element between the isolated position and the contact position.

In some embodiments, the actuator is configured to cooperate in complementary form with an axially extending shaft of the displacement mechanism of the electrical connection base and to drive the shaft in rotation about the axial direction.

For example, the actuator comprises a rod. The stem may be central, but not necessarily. For example, the rod may be a pin. We note that a central pin is in general, but not systematically, a pin for the connection to ground, such a pin being known by those skilled in the art as the pin for the continuity of mass or as the ground contact pin. The central pin is in general different from the other pins (or peripheral pins) of the complementary base of electrical connection.

In some embodiments, the actuator comprises a polarizer.

It is of course understood that such a polarizer is configured to cooperate with a complementary polarizer of the electrical connection base. For example, the rod has a flat forming the key.

In some embodiments, the complementary electrical connection base comprises an index configured to indicate the relative azimuthal position of the complementary base of electrical connection with respect to the electrical connection base.

For example, such an index point, when the complementary base of electrical connection is engaged with an electrical connection base, on a position indicator. This allows the user to perfectly know the relative azimuthal position of the complementary base of electrical connection with respect to the electrical connection base, and therefore the associated position of the mobile element and consequently the connected or unconnected state of the contacts. the electrical connection base with the complementary contacts of the additional electrical connection base. The user can thus avoid any false manipulation. This increases safety and decreases the risk of unwanted arcing.

The present disclosure also relates to an assembly comprising an electrical connection base according to any one of the embodiments described herein and a complementary electrical connection base according to any one of the embodiments described herein. presentation.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

FIG. 1 shows an assembly 100 according to a first embodiment comprising a socket base 10, forming in this example a current connection socket and a connector socket 50, forming in this example a complementary socket for connection of current. The socket base 10 and the connector base 50 each extend in an axial direction X, this direction X corresponding to the direction of fitting (or engagement) of the socket base 10 and connector base 50. The socket base 10 and the connector base 50 have in this example an annular X-axis structure (the X axis defines in this example the axial direction X). In FIG. 1, the socket base 10 and the connector base 50 are disjoint and therefore not in engagement, so that the axial directions X of each of the bases do not coincide, but these directions coincide, of course, when these bases cooperate (see for example Figures 2). In this example, the socket base 10 and the connector socket 50 are each equipped with a handle 80, thereby respectively forming a socket 10A and a plug 50A, the socket assembly 10A and plug 50A forming an extension 100A. Of course, this example is not limiting and any other configuration is possible for the assembly 100, and more particularly for the socket base 10 on the one hand and the connector socket 50 on the other hand.

In this example, the connector base 50 comprises a central pin 52 and six peripheral pins 54, these pins forming, in the sense of the present invention, complementary contacts, while the socket base 10 comprises as many orifices. corresponding, namely a central orifice 22B and six peripheral orifices 22C. Of course, this number of pins and orifices is not limiting, the assembly 100 may comprise more or fewer than seven pins / orifices. In this example the center pin is grounded (i.e. ground pin) while the peripheral pins 54 are each connected to a different phase (i.e. phase pins). In this example, the socket base 10 and the connector socket 50 are of the end contact type.

The socket base 10 comprises a housing 12 having three position indicators to indicate the relative azimuthal position of the socket base 10 relative to the connector base 50, namely a position indicator fitting (or setting 12A), a disconnected position indicator 12B and a connected position indicator 12C. These indicators are respectively formed in this example by a rectangular relief 12A, a writing "FF" 12B relief and a writing "N" relief 12C. These indicators 12A, 12B and 12C may of course have a color different from the color of the housing 12, but not necessarily. The connector base 50 comprises a housing 56 having an index 56A to indicate the relative azimuthal position of the connector base 50 relative to the socket base 10. In this example, the index is formed by a writing "O" in relief 56A. This index 56A may of course have a color different from the color of the housing 56, but not necessarily. For example, the indicators 12A, 12B and 12C and the index 56 may have the same color, this color being distinct from the color of the housings 12 and 56.

These indicators and index form a help of use. Thus, to press or engage the connector base 50 with the socket base 10, the index 56A is azimuthally aligned with the indicator 12A (see FIGS. 5A and 6A). To put the assembly 100 in the disconnected position, the pedestals 10 and 50 are rotated relative to each other so as to azimuthally align the index 56A and the indicator 12B (see FIG. 7A). Note that in this configuration, the index 56A and the indicator 12B form the word "OFF" or "disconnected" in English. To bring the assembly 100 into the connected position, the pedestals 10 and 50 are rotated relative to one another so as to azimuthally align the index 56A and the indicator 12C (see FIG. 8A). Note that in this configuration, the index 56A and the indicator 12C form the word "ON" or "connected" in English.

Thus, when the socket base 10 is not engaged with the connector base 50, as shown in Figures 1, 5A and 5B, or it is only engaged with the base of connector 50 as shown in Figures 6A and 6B, the socket base 10 is in a so-called fitting configuration. When the bases are fitted, and the index 56A and the indicator 12B are aligned, the socket base 10 is in a so-called disconnection configuration. When the bases are fitted, and the index 56A and 12C indicator are aligned, the socket base 10 is in a so-called connection configuration.

The casing 12 has three grooves 12D configured to each receive a pin 56B of the casing 56. This system pins / grooves forms a socket base retaining system 10 with the connector base 50. Thus, the pins 56B can not to be engaged / disengaged in / from grooves 12D only in one position while the bases are fitted and turned relative to each other, the pins 56B are engaged in the grooves 12D so that the connector base 50 is retained in the axial direction X with the base 10. Such a restraint system prevents inadvertent movement in the axial direction X between the socket base 10 and the connector base 50, which prevents the formation of arcing between the pins 54 and the active parts of the tap socket 10 described later. In this example, the retaining system comprises three grooves 12D and three pins 56B but may of course comprises more or less than three grooves and pins.

It is also noted that the housing 12 has two eyecups 12E and 12F while the housing 56 has a 56C eyecup to be able to lock together the socket and connector bases 10 and 50 in the disconnected position (or OFF position) or in position connected (or ON position), for example using a padlock (not shown).

The socket base 10 and the connector base 50 will now be described in more detail with reference to FIGS. 2 and 3. For the sake of clarity, the wires of the cables shown in FIG. 1 are not shown. in Figure 2. In Figure 2, the socket base 10 and the connector socket 50 are fitted.

The socket base 10 comprises a movable element 14, which is movable in the axial direction X between an isolated position (see FIGS. 2, 5B, 6B, 7B, fitting configuration and disconnection configuration of the socket base 10 ) and a contact position (see Fig. 8B, connection configuration of the socket base 10) by a displacement mechanism 16. As will be described in more detail later, the mechanism 16 is configured to move the element mobile 14 from the isolated position to the contact position and vice versa.

The movable element 14 comprises a plate 14A equipped with six distinct portions 14B each configured to contact a peripheral pin 54 of the connector base 50. The plate 14A has guide portions 14A1, in this example axial grooves, configured to cooperate in sliding with complementary portions 29 (see Figure 2), in this example of the axial ribs, a cage 28 receiving the plate 14A. The cage 28 being fixedly mounted on the base 20 (ie immobile relative to the base), the plate 14A is guided in axial translation so as not to pivot about the X axis during the transition from the isolated position to the contact position, and vice versa. In other words, the plate 14A is coupled in rotation with the cage 28 and the base 20.

Each portion 14B comprises a support 14B1 mounted on a spring 14B2 (in this example an axial compression spring) and carrying two contact pads 14B3 and 14B4. The pellets 14B3 and 14B4 are in electrical contact, in this example via the support 14B1 which is electrically conductive. The spring 14B2 makes it possible to exert an axial pressure on the distal end of the corresponding pin 54, to ensure quality end-contact. The portion 14B also comprises a guide 14B5 for guiding the support 14B1 in the axial direction X and housing the spring 14B2. Each portion 14B is received in a dedicated housing 14A1 of the plate 14A.

In this example, each support 14B1 has a rectangular plate shape whose long side extends radially relative to the axis X, the pads 14B3 being disposed radially outwardly relative to the pellets 14B4. The pads 14B4 are configured to contact the pins 54 of the connector base 50 while the pads 14B3 are configured to come into contact with contact elements 15A of the socket base 10. Thus, in this example, in the sense of In the present invention, the contact pads 14B4 form contacts while the pins 54 form complementary contacts.

The contact elements 15A are folded metal bars, connected to the clamps 15B on the one hand, and forming a contact shoulder perpendicular to the axial direction X to contact a contact 14B3 on the other hand. These contact elements 15A and the wire clamps 15B form the active parts of the socket base 10. Such a configuration makes it possible to maximize the space, especially along the azimuthal direction, between the portions 14B, and thus to minimize the risks of forming of electric arc. In this example, the six portions 14B are equidistant and each spaced at an angle of 60 ° about the X axis of the adjacent portion. Thus, the six pellets 14B4 are also equidistant and each spaced at an angle of 60 ° around the X axis of the adjacent pellet 14B4. Similarly, the pellets 14B3 being arranged radially outside the pellets 14B3, are also equidistant and each spaced at an angle of 60 ° around the X axis of the adjacent chip 14B3.

Thus in this example, in the isolated position the movable member 14 is in contact neither with the pins 54 of the connector base 50, nor with the active parts of the socket base 10. In the contact position, the movable element 14 is in contact on the one hand with the active parts of the socket base 10, and more particularly with the contact elements 15A, and on the other hand with the pins 54 of the connector base 50 (see Figure 8B).

The movement mechanism 16 comprises a shaft 18 extending axially and comprising a helical groove 18A and a lug 14C belonging to the movable member 14, and more particularly to the plate 14A. The lug 14C is engaged in the helical groove 18A and cooperates with the helical groove 18A so that the rotation of the shaft 18 around the X axis causes the lug 14C, and therefore the movable member 14, in translation in the axial direction X. Of course, the side walls of the helical groove 18A each form a helical ramp: one cooperating with the lug 14C to move in a first direction in the axial direction X, and the other cooperating with the 14C ergot to move in a second direction, opposite the first direction, in the axial direction X. Of course, the skilled person can easily consider other variants comprising only one helical ramp and for example a system spring return.

The groove 18A has three successive portions

18A1, 18A2 and 18A3. The portion 18A1 extends perpendicular to the axial direction X. The angular extent of this portion 18A1 corresponds to the angular amplitude of the movement required for the transition from the fitting configuration to the disconnection configuration. This portion being perpendicular to the axial direction, during this movement the movable member 14 is not displaced in the axial direction X and remains in the isolated position. The portion 18A2 has an inclination less than 90 ° with respect to the axial direction X. The angular extent of this portion corresponds to the angular amplitude of the movement required for the transition from the disconnection configuration to the connection configuration. This portion 18A2 being inclined relative to the direction X axial inclination of 0 ° and 90 °, the movable member 14 is moved axially from the isolated position to the contact position when switching from the disconnect configuration to the connection configuration. Conversely, the movable member 14 is moved axially from the contact position to the isolated position when switching from the connection pattern to the disconnect configuration. This portion 18A2 extends over a 50 ° angle around the X axis. Thus, the relative angular travel between the socket base 10 and the connector base 50 to move the movable element 14 between the isolated position and the contact position is less than the minimum angle of 60 ° separating two adjacent pellets 14B4. The portion 18A3 is emergent in the axial direction X and parallel to the axial direction X. It serves essentially to mount the socket base 10, and allows the assembly of the movable member 14 with the shaft 18.

The shaft 18 is rotatably mounted on the base 20.

More specifically, in this example, the shaft 18 is partially fitted in a bearing 20A formed in the base 20. The shaft 18 has an axial projection 18D engaged in an annular groove (not shown) of the base s' extending over an angular extent at least equal to the total angular displacement in rotation of the engagement base with respect to the connector base around the axial direction X. This projection 18D forms a polarizer for the assembly of the shaft 18 with the base 20 during the manufacture of the socket base 10.

To be rotated, the shaft 18 is hollow, and has at its distal end opposite the end engaged in the bearing 20A, a cavity 18C of square cross section, this square section having in an angle a flattened 18C1 forming a key. This cavity 18C is configured to receive the central pin 52 described later. For the purposes of the present invention, the pin 52 forms an example of complementary element configured to cooperate in complementary form with the shaft 18.

The shaft 18 carries a safety disc 22. The safety disc 22 is coupled in rotation with the shaft 18 by a tenon / mortise system 22A / 18B. The safety disk 22 is carried by the distal end of the shaft 18, opposite the end engaged in the bearing 20A of the base. The movable element 14 is disposed between the base 20 and the disc 22. The security disc 22 has a central orifice 22B and six peripheral orifices 22C configured to receive respectively the central pin 52 and the peripheral pins 54 of the connector base 50. The security disc 22 has walls forming separators 22D , each being arranged on the side of the movable element 14 between two adjacent orifices 22C. These separators serve to prevent arcing between a first pin 54 and a chip 14B4 configured to contact a second pin 54, adjacent to the first pin.

The safety disk 22 being carried by and coupled in rotation with the shaft 18, it is rotatable about the axis X. When the shaft 18 is in a position such that the movable member 14 is in isolated position, the safety disk 22 blocks access to the pellets 14B4 of the movable element 14 (ie the orifices 22C and the pads 14B4 have a distinct azimuthal position and are not vis-à-vis in the direction axial X). The safety disk 22 is then in the protection position. When the shaft 18 is in a position such that the movable element 14 is in the position of contact, the safety disk 22 allows access to the pellets 14B4 of the movable element 14 (ie the orifices 22C and the pellets 14B4 present the same azimuth position and are vis-à-vis in the axial direction X). The security disk 22 is then in the connection position.

The gripping base 10 comprises a holding device 24 for holding in position the movable member 14. This holding device 24 comprises two similar 18E cams and arranged at 180 ° to each other relative to the axis of the shaft 18, and two similar pressers 26, each pressing element 26 cooperating with a cam 18E. The pressing elements 26 are fixed to the base 20, and are therefore stationary relative to the shaft 18, and therefore not related to the cams 18E.

The cams 18E and the pressers 26 are described in more detail with reference to FIG. 4. The two cams and the two pressers being identical, only one cam / pressing torque is described. Of course, the present example comprises two cam / presser couples, but could of course include only one, or more than two.

The cam 18E extends azimuthally between two stops 19A and 19B and has two teeth 18E1 and 18E2. The element presser 26 has a needle 26A mounted on a spring 26B which radially presses the needle 26A against the cam 18E. The needle 26A, and more generally the pressing element 26 cooperates by complementarity of shape the cam 18E. Thus, the pressing element 26 provides a certain resistance when it is desired to rotate the shaft 18, this resistance resulting from the passage of the needle 26A on the teeth 18E1 or 18E2. The first tooth 18E1 is smaller than the second tooth 18E2, so that the resistance provided to pass the first tooth 18E1 is less than the resistance provided to pass the second tooth 18E2.

When the needle 26A is disposed between the abutment 19A and the first tooth 18E1, the connector base 10 is in the fitting configuration, the movable element 14 being in the isolated position (the lug 14C being disposed in the portion 18A1 of the helical groove 18A). When the needle 26A is between the first tooth 18E1 and the second tooth 18E2, the connector base 10 is in the disconnection configuration, the movable element 14 being in the isolated position (the lug 14C being disposed in the groove portion 18A1 helical 18A, in the vicinity of the inclined portion 18A2). When the needle 26B is disposed between the second tooth 18E2 and the stop 19B, the connector base 10 is in connection configuration, the movable element 14 being in the contact position (the lug 14C being in the groove portion 18A2 helical 18A).

Thus, thanks to the teeth 18E1 and 18E2 and the pressing member 26, only the configurations taken by the socket 10 when the needle 26A is between the stop 19A and the first tooth 18E1, between the first and second teeth 18E1 and 18E2 and between the second tooth 18E2 and the stop 19B are stable configurations. All configurations taken by the socket base 10 when the needle cooperates with one side or the top of a tooth 18E1 or 18E2 are unstable configurations. Indeed, in the latter case the pressing member 26 exerts a radial pressure tending to rotate the cam 18E about the axis X so as to return to a stable position where the pressing member 26 is between two teeth or between a tooth and a stop. Of course, a person skilled in the art can use any other known system which makes it possible to obtain a similar stability of the different configurations, namely at least a first stable configuration in which the movable element is in the contact position (ie stable connection configuration), a second stable configuration in which the movable element is in isolated position (ie stable disconnection configuration) and a plurality of unstable intermediate configurations between the first configuration and the second configuration in which the socket base tends to come in the first configuration or in the second configuration.

It is therefore understood that the pressing member 26 holds the shaft 18 in position such that the needle 26A is disposed between two teeth or between a tooth and a stop, and opposes movements tending to clear the needle of these positions. By maintaining the shaft 18 in predetermined positions (ie azimuthal position where the needle 26A is disposed between two teeth or between a tooth and a stop), the cam 18E and the pressing element 26 make it possible to maintain the movable element 14 either in the contact position, either in the isolated position. It is noted that the passage of the second tooth 18E2 requires a voluntary movement on the part of the user to reach the top of the second tooth 18E2. Beyond this vertex, the holding device 26 assists the user and the end of the movement is done automatically. The speed of rotation of the shaft, and therefore the speed of displacement in the axial direction of the movable element 14, is a function in this second phase, of the pressure exerted by the pressing element 26 on the cam 18. thus to control this speed, and thus the formation of electric arc during the connection / disconnection of the pellets 14B4 with the pins 54.

Moreover, the first tooth 18E1 makes it possible to oppose a certain resistance during the transition from the fitting configuration to the disconnection position, and vice versa. This provides some security for the user. Indeed, when the bases are mounted within an extension as shown in Figure 1 and the socket base 10 is in a disconnected position, the bases can undergo some torsional stress through the electrical cables to which they are connected. These constraints could lead to bringing the socket base into a fitting configuration, so that the socket base 10 could disengage from the base of the socket. connector 50, which is undesirable. Thus, the resistance provided by the first tooth 18E1 avoids this risk.

In general, it is noted that the base 20 forms a stationary element of the socket base 10. The base 20 receives from one side the clamps 15B, and a central wire clamp 15C connected a central contact 15D alveolar configured to receive the end of the central pin 52. The pin 52 being connected to the ground, the central contact 15D is obviously also connected to the ground (ie ground contact). The base 20 receives on a second side, opposite in the axial direction X to the first side, the feed mechanism 16 and the holding device in position 24. This second side of the base 20 also receives a cage 28 housing the housing. movable element 14 and serving as a bearing on the safety disc 22. The contact elements 15A are arranged outside the cage 28. All this assembly is received in the housing 12, the base 20 being locked within the housing 12 by a ring 30 and stationary within the housing 12. In other words, the base 20 is coupled to the housing 12. The housing 12 is equipped with a seal 32 to ensure a certain level of tightness to the water and foreign bodies when the socket base 10 and assembled with the connector base 50.

The cage 28 has a cylindrical portion 28A X axis configured to guide the plate 14A axially between the isolated position and the contact position and a perforated portion 28B, transverse to the axial direction X, to allow the passage of the pins 52 and 54.

The connector base 50 comprises a central pin 52 which forms an actuator configured to actuate the movement mechanism 16 of the movable member 14 of the socket base 10. In this example, the central pin 52 is formed by a rod extending axially. More specifically, the central pin 52 has a square section, a corner has a flat 52A forming a polarizer. This pin 52 is configured to engage in the cavity 18C of the shaft 18 and cooperates in complementary form with the walls of this cavity 18C In other words, in this example, the central pin 52 forms a complementary element configured to cooperate in complementary form with the shaft 18. Thus, when the socket base 10 is engaged with the connector base 50, the pin 52 is fitted into the shaft 18 and coupled in rotation with the shaft 18. Thus, when turning the socket base 10 and the connector socket 50 relative to each other about the X axis, the pin 52 drives the shaft 18 in rotation, whereby the mechanism of moving 16 of the movable member 14 is actuated.

The various phases of use of socket socket

10 and the connector base 50 will now be described with reference to FIGS. 5A to 8B. For the sake of clarity, the wires of the cables shown in FIG. 1 are not shown.

In FIGS. 5A and 5B, the socket base 10 and the connector base 50 are separated and in approach in the axial direction X. The socket base 10 is in the fitting configuration, the mobile element 14 being in the isolated position and the needle 26A of the two pressing elements 26 disposed between the stop 19A and the first tooth 18E1. The bold arrow indicates the movement of engagement of the socket base 10 and the connector socket 50. As indicated above, to engage the connector socket 50 with the socket base 10, the index 56A is azimuthally aligned. with the indicator 12A as shown in FIG. 5A. Of course, the socket base 10 and the connector socket 50 are configured such that when the index 56A and the indicator 12A are azimutally aligned, the pins 56B are aligned with the entries of the grooves 12D, and the key 52A the pin 52 is aligned with the displacement mechanism key 18C1. The ports 22C of the security disc 22 are also azimuthally aligned with the peripheral pins 54.

Thus, by engaging the socket base 10 and the connector base 50 in this way, they are engaged. It will be noted that, in the general sense of the present description, the pedestals are considered to be engaged when the actuator of the connector base and the mechanism of displacement of the socket base cooperate in such a way as to be able to actuate the movement mechanism (ie in the present example, the pin 52 is engaged in the shaft 18). Thus, it is understood that the pins 56B and the grooves 12D are optional.

In FIGS. 6A and 6B, the socket base 10 and the connector base 50 are engaged. The pin 52 extends through the orifice 22B and is fitted into the cavity 18C of the shaft 18. The pins 54 extend through orifices 22C. The socket base 10 is in fitting configuration, the movable element 14 being in isolated position and the needle 26A of the two pressing elements 26 disposed between the stop 19A and the first tooth 18E1. Central pin 52 is in electrical contact with central contact 15D while movable member 22 is remote from peripheral pins 54 and contact members 15A.

By rotating the socket base 10 and the connector base 50 relative to each other about the axis X, so as to bring the index 56A on the indicator 12B (see arrow in Fig. 6A), the plug base 10 is brought into the disconnected configuration shown in Figs. 7A and 7B. The pin 52 has driven the shaft 18 in rotation about the X axis, so that the needle 26A of the two pressing elements 26 is disposed between the first tooth 18E1 and the second tooth 18E2. The lug 14C is at the foot of the inclined portion 18A2 of the helical groove 18A. The movable element 14 is thus always in isolated position and remains remote from the peripheral pins 54 and the contact elements 15A. The central pin 52 is always in electrical contact with the central contact 15D. In addition, the peripheral pins 54 have followed the rotational movement and have driven the security disk 22. Thus, the pins 14 have approached in the azimuthal direction of their respective pads 14B4 but are still not aligned azimuthally with the pads 14B4.

By rotating the socket base 10 and the connector base 50 relative to each other about the axis X, so as to bring the index 56A on the indicator 12C (see arrow in Fig. 7A), the plug base 10 is brought into the connected configuration shown in Figs. 8A and 8B. The pin 52 has driven the shaft 18 in rotation about the X axis, so that the needle 26A of the two pressing elements 26 is disposed between the second tooth 18E2 and the stop 19B. The lug 14C has been driven in the X direction by the inclined portion 18A2 of the helical groove 18A, so that the movable member 14 has moved from the isolated position to the contact position. The pellets 14B4 are in contact with the pins 54 which, thanks to this latter rotation, are aligned azimuthally with the pellets 14B4. In addition, the pellets 14B3 are in contact with the contact elements 15A. The supports 14B1 being electrical current conductors, the pins 54 are thus in contact with the active parts of the socket base 10. On note that the springs 14B2 supporting the supports 14B1 are compressed and thus exert a certain pressure in the axial direction on the pins 54 and the contact elements 15A, via the pellets 14B3 and 14B4.

With the movement mechanism 16 of the movable member 22 and the holding mechanism in position 24 of the movable member 22, the contact between the active parts of the socket base 10 and the pins 54 of the connector base 50 is perfectly controlled and independent of the speed of fitting of the two bases. In this example, the contact is made during the transition from the disconnection configuration to the connection configuration of the socket base 10. The axial distance separating the pellets 14B4 of the pins 54 in the isolated position is at least 6 mm. Thus, the risk of arcing during connection is avoided, at least minimal.

Of course, to bring the socket base 10 in disconnected configuration, then in fitting configuration, and finally to unmount the two bases of one another, it operates the relative movements between the two pedestals opposite to those described above with reference to FIGS. 5A to 8B. In the same manner as described above, the disconnection speed is identical to the connection speed, so that the risk of arcing during disconnection is also avoided, at least minimal.

A second embodiment will now be described with reference to FIGS. 9 and 10. FIG. 9 represents an assembly 200 comprising a socket base 110, forming in this example a complementary socket for current connection, and a socket of FIG. connector 150, forming in this example a current connection base. In other words, in comparison with the first embodiment, the socket base 110 includes an actuator for actuating a mechanism for moving a movable element of the connector socket 150 while in the first embodiment it is the connector base 50 which comprises an actuator for actuating a mechanism for moving a movable element of the socket base 10. Note that in this example the movement mechanism of the movable element and the holding device in position are identical between the first embodiment and the second embodiment. Only the moving element changes: instead of wearing contact pads as in the first embodiment, it carries pins. Note that in Figures 9 and 10 the bases are not equipped with a handle, but can of course be equipped.

The housings 112 and 156 of the socket bases 110 and connector 150 are similar to the housings 12 and 56 of the bases 10 and 50 of the first embodiment, with the exception of locking eyelets that are not provided. Of course, the indicators and indexes are present, although they are not visible in the figures.

The socket base 110 comprises an insulating body 121 mounted on a base 120 which are fixed relative to the housing 112. The body 121 and the base 120 form six peripheral housing 121A each receiving a braid 115A end contact, these braids 115A being configured to make an end contact with the pins 154 described later. Of course, according to one variant, there are more or less six peripheral dwellings equipped with a braid. Braids 115A form, within the meaning of the present invention, complementary contacts. A central housing 121B receives a central pin 115B. This center pin 115B is similar to the pin 52 of the connector base 50 of the first embodiment, and serves as an actuator for actuating the displacement mechanism (described later) of the connector base 150. The pin 115B has in particular a non-polar keying element. shown similar to the polarizer 52A, which cooperates with a polarizer 118C described later. The socket base 110 also includes a security disk 122, similar to the security disk 22 of the socket base 10 of the first embodiment. The safety disc 22 is rotatably mounted on the insulating body 121, and is rotated between the protective position and the connection position by the pins 154 of the connector base 150.

The connector base 150 comprises a movable element 114, which is movable in the axial direction X between an isolated position (not shown) and a contact position (position shown in Figure 9) by means of a displacement mechanism 116 In a manner comparable to the moving mechanism 16 of the first embodiment, the mechanism 116 of the second embodiment is configured to move the movable member 114 from the isolated position to the contact position and vice versa. The movable member 114 comprises a plate 114A equipped with six separate pins 154 each configured to contact a braid 115A socket base 110. Of course, according to one embodiment, there are more or less than six pins. The pins 154 are of course integral with the plate 114A. The pins 154 form, in the sense of the present invention, contacts. Each pin 154 is electrically connected to a wire clamp 157, mounted on the base 158, by a flexible wire 160. Of course, it is understood that when the plate 114A moves axially, it drives the pins 154, while the clamps son 157 remain in position relative to the base 160, the flexible son folding / leaflet to follow the movements of the tray 114A. Thus, not "flexible wire" is meant a wire capable of deforming as a function of the axial displacements of the movable element 114. Therefore, in this example, the bores of the movable element are in permanent contact with the wire clamps. .

[0099] Similarly to the plate 14A of the first embodiment, the plate 114A has guide portions 114A1, in this example axial grooves, configured to cooperate in sliding with complementary portions 163, in these example ribs, d a cage 162 receiving the tray 114A. Similarly to the cage 28 of the first embodiment, the cage 162 has a cylindrical portion 162A of X axis configured to guide the plate 114A axially between the isolated position and the contact position and a perforated portion 114B, transverse to the axial direction X, to allow the passage of the pins 115B and 154.

Similarly to the displacement mechanism 16 of the first embodiment, the displacement mechanism 116 comprises an axially extending shaft 118 comprising a helical groove 118A and a lug 114C (see FIG. 10) belonging to the movable member 114, and more particularly to the tray 114A. The shaft 118, and in particular the groove 118A, is strictly similar to the shaft 18 of the first embodiment, and in particular the groove 18A, and is therefore not described again.

The shaft 118 is rotatably mounted on the base 160 similarly to the first embodiment. To be rotated, the shaft 118 is hollow, and has at its opposite distal end engaged with the base 160, a cavity 118C of square cross section, this square section having in a corner a flat 118C1 forming a polarizer. This cavity 118C is configured to receive the central pin 115B of the socket base 110.

The connector base 150 also comprises a holding device in position 124 for holding the movable element 114 in position. This holding device 124 comprises two similar 118E cams and arranged at 180 ° from each other by relative to the axis of the shaft 118, and two similar pressers 126, each pressing element 126 cooperating with a cam 118E. The pressing elements 126 are fixed to the base 160, and are therefore immobile with respect to the shaft 118, and therefore not related to the cams 118E. The pressing elements 126 and the cams 118E are strictly similar to the pressing elements 26 and cams 18E of the first embodiment, and are therefore not described again.

The different phases of use of the socket socket

110 and the connector base 150 are similar to the phases of use of the socket base 10 and the connector base 50 of the first embodiment, and are therefore not described again. Of course, instead of bringing pellets 14B4 in contact with the pins 54 from the isolated position to the contact position, in the second embodiment the movable element 114 brings the pins 154 in contact with the braids 115A. The kinematics of all the other elements remains quite comparable between the first and second embodiments.

It is generally understood that the socket base 10 of the first embodiment and the connector socket 150 of the second embodiment form electrical connection bases which respectively comprise contacts 14B4 and 154 configured to contact complementary contacts. 54 and 115A, respectively, of the connector socket 150 of the first embodiment and the socket base 110 of the second embodiment which form complementary electrical connection bases.

Although the present invention has been described with reference to specific exemplary embodiments, it is obvious that modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the revendications. In particular, individual characteristics of various illustrated / mentioned embodiments may be combined in additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than restrictive sense.
