Description

AXIAL ION ROTATING DEVICE FOR CONNECTING CORDS
TELEPHONE, COMPUTER, ELECTRIC.

 The present invention relates to a device with axial rotation for connection of this twisted or spiraled cords composed of multi-strand or single-strand, flexible or semi-flexible conductive tils, making it possible to remove, during normal use, the tangling of these wires or cords.

 the connections by cords and sockets are traditionally carried out using fixed connectors, such as cords fitted with connectors for electrical, elepnonic and niormatic connections. These rixed sets, embedded in a wall outlet or other standardized, generate during normal use of entanglement eventually hampering the user, and often cause breakage of copper wires. The device according to the invention overcomes this drawback. 11 has in effect an axially rotating part rotating on a fixed assembly whose end, comprising a conre: eur or a pr-se this standard current female or male, will be plugged into the standardized fixed socket, wall or other.

This dispositi @ reflects a roation these wires OR the cord on 3500 without user eifort, unlike the standard connector yes, plugged into a standard wall or other rise, remains fixed.

There are 360 rotation systems (US: 3,195,094 and
PCT / US55 / 00112 or WO85 / 03388) in which the contacts are made raaial on aes coaxial cylindrical bodies.

 The rotating part of the case is particularly designed to be made of plastic, in a single injection molding operation.

 According to a variant, the outlet zone on the mobile housing forming the connection for the connection of the connecting wires has been designed to receive the most common types of cords.

 Figures 1, 2 and 3 show in section the device according to the invention. LeE Figures 4, 5 and - show in section the variants of the device. Figures 8 and 9 show applications.

 The device shown in FIG. 1 comprises a housing (1) having dimensions on the order of 2 centimeters for the diameter and 2.5 centimeters for the length. In the inner part of the housing (1) Fig 3, 4 or more housings obtained from molding will allow to receive the prepared and stripped wires of the cord (12) which will be introduced through the orifice of the rotary case (1) provided for this purpose . The wires will be crimped onto the contact blades (7) which, crimped through the insulation (15), allow contact with each wire (14) of the coraon (12). Each connection assembly will be positioned in each of the housings obtained @ m from the housing (1). The contact springs (8) have entered a positioning washer (9) which is itself immobilized by the centering feet. (10).

 he device shown in FIG. 2 comprises a cylindrical part in which the printed circuit with double-sided cylindrical tracks (3) with metallized holes (4) is positioned by 3 heels. This printed circuit with cylindrical tracks (3), centered in the bottom of the fixed device 2), will ensure, after mounting in the rotating part (1), the continuity of the electrical connections between the standard connector (11), the contact pins (16) and the contact springs (8) - Figl.

 According to a variant Fig 4, 5 and 7, the printed circuit with pis tes cy ylindriques' =) double face with metallized holes has ccncave tracks whose characteristic is to center the wires (19) to ensure contacts between the second circuit printed with concave cylindrical tracks (3) placed in the rotating part (1).

 The connections between the printed circuits (3) and the pins (16) are provided by the contact blades (7). The whole of the printed circuit t with concave cylindrical tracks (3) integral with the rotary part (1) is under the thrust of the springs (8) permanently ensuring the continuity of the electrical contacts despite the slight axial displacement of the printed circuit.

 t which of all the rotational movements over 360 of the rotating part (1) on the fixed part (2) is obtained by the friction washer '5) held by the centering and fixing collar E; ensuring the solidarity of the fixed part (2) by gluing in the removal of the rotary part (1).

 The fixed part (2), which will receive the standard connector or socket, is personalized for each type of connector or socket in injection molding. the diameters of the assembly that constitutes the axial rotation device are different and adapted according to the types of electrical, telephone and IT power sockets. The device according to the invention is characterized by the basic quality of the materials chosen such as: sintered bronze, beryllium bronze, copper, gilding, nickel, stainless spring steel, epoxy glass, rigid and friction plastics.
