Definitions
- the present invention relates to a charger for electrical apparatus.
- the size of such a charger is often important, especially because of its thickness, so that when it is shipped to a customer by a routing or courier service, such as the public postal service or a private company, it can not be considered as a simple letter in view of its dimensions. It is also impossible to pass it in the standardized slot of the customer's mailbox because its dimensions are too large.
- the charger can be shipped only in the form of a package, which requires the deliveryman to open the mailbox and therefore to have the key. However, this is not always the case, especially if a private parcel forwarding company is used. Delivery of the charger is therefore more expensive and often longer, which can be a disadvantage for the customer as well as for the supplier who risks losing sales.
- An object of the present invention is therefore to solve the problem mentioned above with a solution that is simple to implement, reliable and inexpensive.
- the present invention relates to an electric charger intended to be plugged into a standard power outlet to allow powering an electrical device, characterized in that it is made of several parts that can be assembled by the user each piece having dimensions such that it can be introduced into a slot of a determined width.
- the figure 1 represents an electric charger 1 according to the present invention, intended to be plugged into a standard power outlet, for example to the British standard. As represented on the figure 1 , the charger 1 is in its final state assembled by the user, that is to say ready to be used. This charger 1 has the function of supplying power or recharging an electrical device, such as a camera, a cell phone or an MP3 player, via a suitable cable (not shown).
- an electrical device such as a camera, a cell phone or an MP3 player
- the charger 1 comprises a main housing 10 of plastics material of substantially parallelepiped shape.
- the housing 10 is in two parts and has a thickness E.
- Two electrical connection pads 12 and 14, respectively the phase and the neutral, are raised from an upper face 5 of the housing 1 (visible on the figure 2 ) and are parallel to them. These pads are made of copper and have identical dimensions (length, section).
- the main housing 10 is provided, opposite its upper face 5, an electrical connection 8 type USB (Universal Serial Bus) allowing the charger to be connected to the electrical device to power or recharge.
- USB Universal Serial Bus
- the charger 1 also comprises a spacer 20 intended to be mounted on a front face 11 of the housing 10, and a support 30 for a third electrical connection pad 16, said support being intended to be fixed on the spacer 20.
- the third stud electrical connection 16 is the ground connection pad.
- the housing 10, the spacer 20 and the support 30 of the third connection pad 16 have dimensions such that each of these parts can be introduced into a slot of a given width, for example the slot of a standardized mailbox (for example the British standard) measuring 21 mm wide.
- the thickness E of the main housing 10 is less than 21 mm, for example 19 mm.
- the Figures 2 to 4 also illustrate three assembly steps to be performed by the user of the charger 1 once he has recovered the charger in his mailbox in the disassembled state.
- the main housing 10 is provided with its two electrical connection pads, as will be explained later in connection with the Figures 5 and 6 .
- first fastening means 22 are provided in the form of two parallel elastic tabs 24 extending perpendicularly to the spacer 20 and a corresponding opening 15 formed in the main housing and with which the tabs collaborate.
- the support 30 of the third electrical connection pad 16 is mounted on the spacer by means of second attachment means 32.
- These second attachment means 32 are constituted by two parallel elastic tabs 34 extending from the support 30 of the third electrical connection pad 16 by a corresponding opening 25 formed in the plate and aligned with the opening 15 of the main housing 10.
- the three electrical connection pads 12, 14 and 16 have dimensions and a triangle arrangement adapted to be introduced into holes arranged in the standard socket.
- the main housing 10 further contains a printed circuit board 40 mounted vertically and carrying the first two electrical connection pads 12 and 14.
- the main housing 10 encloses a double metal contact 18 made of copper electrically connecting the third electrical connection pad 16 to the printed circuit board 40 with the aid of, for example, a pin (not shown) projecting from the support.
- attachment means 22 and 32 may be modified as long as they allow the spacer 20 to be securely attached to the housing 10 and the support 30 to the spacer 20.
- the spacer 20 and the support 30 may form a single piece having the dimensions adapted so that the magazine 1 in the disassembled state can be slid into the slot of a standardized mailbox having a width of 21 mm.

Abstract
Description
La présente invention concerne un chargeur pour appareil électrique.The present invention relates to a charger for electrical apparatus.
Les chargeur actuels destinés à être branchés dans une prise de courant normalisée pour alimenter un appareil électrique, que ce soit à la norme française, britannique ou américaine, sont vendus d'un seul bloc déjà monté, par exemple sous un blister.Current chargers intended to be plugged into a standard power outlet to power an electrical appliance, whether to the French, British or American standard, are sold as a single block already mounted, for example in a blister.
Or, l'encombrement d'un tel chargeur est souvent important, notamment à cause de son épaisseur, de sorte que lorsqu'il est expédié à un client par un service d'acheminement ou de messagerie, tel que le service postal public ou une société privée, il ne peut pas être considéré comme une simple lettre au vu de ses dimensions. Il est en outre impossible de le faire passer dans la fente normalisée de la boîte à lettres du client car ses dimensions sont trop importantes. Ainsi, le chargeur ne peut être expédié que sous la forme d'un colis, ce qui impose au livreur d'ouvrir la boîte à lettres et donc d'en avoir la clé. Or, ceci n'est pas toujours le cas, notamment si une société privée d'acheminement du colis est utilisée. La livraison du chargeur est donc plus coûteuse et souvent plus longue, ce qui peut être un inconvénient pour le client ainsi que pour le fournisseur qui risque de perdre des ventes.However, the size of such a charger is often important, especially because of its thickness, so that when it is shipped to a customer by a routing or courier service, such as the public postal service or a private company, it can not be considered as a simple letter in view of its dimensions. It is also impossible to pass it in the standardized slot of the customer's mailbox because its dimensions are too large. Thus, the charger can be shipped only in the form of a package, which requires the deliveryman to open the mailbox and therefore to have the key. However, this is not always the case, especially if a private parcel forwarding company is used. Delivery of the charger is therefore more expensive and often longer, which can be a disadvantage for the customer as well as for the supplier who risks losing sales.
Un but de la présente invention est donc de résoudre le problème cité précédemment à l'aide d'une solution simple à mettre en oeuvre, fiable et peu coûteuse.An object of the present invention is therefore to solve the problem mentioned above with a solution that is simple to implement, reliable and inexpensive.
Ainsi, la présente invention a pour objet un chargeur électrique destiné à être branché dans une prise de courant normalisée pour permettre d'alimenter un appareil électrique, caractérisé en ce qu'il est réalisé en plusieurs pièces susceptibles d'être assemblées par l'utilisateur, chaque pièce présentant des dimensions telles qu'elle peut être introduite dans une fente de largeur déterminée.Thus, the present invention relates to an electric charger intended to be plugged into a standard power outlet to allow powering an electrical device, characterized in that it is made of several parts that can be assembled by the user each piece having dimensions such that it can be introduced into a slot of a determined width.
