Description

electric socket

technical field

The invention relates to an electrical socket of the household type comprising a body integrating a plug receiver having a front surface in which insertion holes designed to receive contact pins of an electrical plug are arranged. The movable protection flap is capable of adopting two operating positions: a first position, called the access position, which allows access and connection of the electrical plug; and a second position, called the non-access position, which prevents access to the insertion hole. the

Background technique

Access to electrical outlets designed to distribute electricity to electric vehicles is regulated. In practice, electrical sockets are generally equipped with safety devices allowing or preventing the connection of a plug to said socket. the

Allowing connections generally requires an upfront payment from the customer to the distribution manager. the

The security device can be used to prevent any connection by a person who does not have access rights and cannot connect to his/her vehicle without prior payment, for example. the

The security device can also be used after the plug has been connected by a first user with access rights. This type of operation ensures that a second user cannot connect, replace and replace the first user. the

The use of safety devices to prevent access to distribution outlets is described. For example, the locking device may be coupled to an access tab designed to be placed in a telescoping manner in front of the plug receptacle of the receptacle subassembly. The plug receiver comprises in particular an insertion hole designed to receive the pins of the plug. the

In the first position, the tab prevents the plug from being seated in the socket, except during electrical connection, in particular during charging. Locking means disable the flaps in this first operative position, thereby also ensuring tightness. When charging takes place, the locking means is disabled and the tabs are then positioned in the second operative position enabling connection of the plug to the socket. For this purpose, the plug can be connected to the electric vehicle. The access tab is then closed on the plug and the locking device is operable again. the

The size, volume and shape of household-type plugs vary from one application to another, especially from one type of vehicle to another. For the same socket, in particular a recharging socket, several types of plugs can thus be designed to be connected. To accommodate a large variety of plugs, the access tabs have to be overdimensioned in order to ensure, for example, efficient utilization of small and large plugs. This size design for accommodating the largest plug presents the disadvantage of increasing the overall size of the recharging terminal incorporating one or more electrical sockets. the

Detailed ways

According to an embodiment of the present invention as shown in FIG. 1 , an electrical socket 100 includes a socket body 1 having a front surface in which an insertion hole 101 is arranged, and the insertion hole 101 is designed to receive a contact pin 201 of an electrical plug 200 in a connection position. . the

The electrical socket according to the invention comprises movable protective flaps 2 . the

As shown in Figures 3 and 4, the flap 2 can assume two operative positions. A first position ( FIG. 2 ), called the access position, allows access and connection of an electrical plug 200 to the electrical socket 100 according to the invention. The second position ( FIG. 3 ), called the non-access position, prevents access to the insertion hole 101 designed to receive the contact pin 201. Furthermore, the second position, referred to as the non-access position, also prevents access to a previously connected electrical plug 200 . The tab 2 is generally connected to the socket body 1 by a hinge type mechanism so as to be mounted to pivot on a hinge pin 7 . Said mechanism enables said vane 2 to rotate about a first axis of rotation Y between a first and a second operative position. As an exemplary embodiment, the flap 2 can perform a rotation of at least 90° between the first and second operating positions. the

The tab 2 can be placed in the second operative position (non-access) for connecting or not connecting the plug 200 to the socket 100 . the

When the flap 2 is placed in the second operating position (non-access), the through space 111 is arranged between the socket main body 1 and the flap 2 . The passage space 111 is designed for connecting the main body 203 of the electrical plug 200 to an electrical device, in particular such as an electric vehicle (not shown), via a cable 205 . the

According to a particular embodiment, the electrical socket 100 comprises flexible biasing means 8, 9 designed to exert a spring force responsible for generating a rotational torque, bringing the flap 2 about a first axis of rotation Y between a first and a second operative position rotate. Advantageously, the flexible biasing means 8 , 9 each comprise a torsion spring wound around the hinge pin 7 aligned with the first axis Y of rotation. the

In the second operating position, the electrical socket 100 comprises the locking means 40 of the tabs. The tab 2 can be locked in the second operative position, regardless of whether the plug 200 is connected to the socket 100 or not. Locking device 40 generally comprises an electromagnet engaging a movable bolt (not shown). The locking device 40 shown in Figures 6 and 7 can be controlled remotely via hardwired or wireless means. In both cases, the aim is to prevent access to the electrical socket 100 by any unauthorized person. the

The front surface of the socket is provided with a plug receiver. Preferably, the plug receiver 10 includes an insulating base provided with insertion holes 101 for electric pins/prongs of the electric plug 200 . the

According to a particular embodiment as shown in FIG. 1 , the plug receptacle 10 comprises a stand 11 in which a base portion 12 is positioned. The base portion is provided with an insulating bottom including an insertion hole 101 . the

As an exemplary embodiment, the insulating bottom may have a square shape or a circular shape. Each hole of an electrical pin/fork 201 designed to receive an electrical plug can be accessed into an electrical terminal, said electrical terminal being designed to be connected to an electrical conductor not shown. According to a preferred embodiment of the present invention, the plug receiver 10 is rotatable relative to the socket body. The plug receiver can assume two operating positions. The plug receiver is typically connected to the socket body by a hinge type mechanism. The mechanism is capable of rotating the receptacle about a second axis of rotation Z between a first and a second operating position. According to a particular embodiment, the first axis of rotation Y and the second axis of rotation Z may preferably coincide. The plug receiver is then mounted to pivot on at least one hinge pin 7. the

The first position is called the non-retracted position, in which the plane formed by the insulating bottom of the plug receiver 10 is substantially parallel to the plane formed by the tabs 2 placed in the second operative position (non-access). the

The second position is called the retracted position, in which the plane formed by the insulating bottom of the plug receiver 10 has been rotated relative to the first position. As in the exemplary embodiment, the angle of rotation between the two operating positions of the plug receiver is substantially equal to 60°. This receiver may be referred to as a retractable plug receiver. the

The plug receiver 10 moves from the first position (non-retracted) to the second position (retracted) due to the thrust on said plug receiver. The thrust is responsible for generating a rotational torque, rotating the plug receptacle about the second axis of rotation Z. The thrust is generally applied indirectly by the user, connecting the electrical plug to the electrical outlet. the

According to a specific embodiment not shown, the electrical socket 100 comprises flexible biasing means capable of exerting a spring force responsible for generating a rotational torque for the plug-receiver about the second axis of rotation Z in the second operative position and in the second position. Rotate between operating positions. In fact it may be preferred that the plug receptacle is movable from the retracted position to the non-retracted position due to the spring force. Advantageously, the flexible biasing means may comprise a torsion spring wound around the second axis Z of rotation. the

The electrical socket 100 according to the invention comprises directional drive means. Orientation drives mechanically connect the flap 2 to the plug receiver 10 . A one-way mechanical coupling is established between the flap and said receptacle, so that movement of the flap 2 from the second position (non-inserted) to the first operative position (connected) in turn causes the plug receiver 10 to move from the first position to the receptacle. Movement of the second position (retracted) to the first operating position (non-retracted). Furthermore, maintaining the tab 2 in the first operative position (engaged) locks the rotation of the plug receptacle 10 in the first operative position (non-retracted). the

In the exemplary embodiment shown in FIGS. 5A and 5B , the unidirectional drive means comprise a first drive latch 21 arranged on a pawl 20 of the movable flap 2 . The directional drive also includes a second drive latch 13 arranged on the bracket 11 of the plug receiver 10 . The two latches 21 , 13 comprise suitable shapes so as to contact each other only during movement of the flap 2 from the second position (non-engaged) to the first operative position (engaged). Thus, during this opening movement of the flap 2 the two latches 21 , 13 will be in contact and cooperate such that movement of the flap 2 causes movement of the plug receiver 10 . The cooperation of the latch 21 of the flap 2 with the latch 13 of the bracket 11 thus prohibits movement of the plug receptacle 10 when the flap 2 has reached its first operating position (plugged in). the

When the flap 2 is rotationally moved from the first position to the second position, the two latches 21 , 13 are no longer in contact, so the movement of the flap 2 is de-correlated from the movement of the plug receiver 10 . the

A user wishing to connect the electrical plug 200 to the electrical socket 100 must therefore first open the flap 2 by placing it in the first operating position (plug in), and keep it in this position. The plug receiver 10 is then blocked in the first operating position (non-retracted) by the one-way drive means 21 , 13 . Then, the user can connect the plug 200 without retracting the insulating bottom of the plug receiver 10 due to the pressure applied by the user, thereby connecting the plug 200 . Once this has been done, the user will close the flaps, positioning the latter in a second operating position, called the non-access position. Flexible biasing means (torsion springs 8, 9) facilitate this movement. Depending on the shape of the electrical plug and its volume, the fin 2 may press against the electrical plug 200 during the rotational movement of the fin 2 . By pressing on the electrical plug 200 , the fins 2 then tend to exert a thrust responsible for generating a rotational torque, rotating the plug receiver 10 about the second axis of rotation Z. the

As an exemplary application, household type sockets are especially suitable for electric vehicles. the
