Description

DESCRIPTION OF THE INVENTION

[001] The invention relates to a connector comprising a connector plug and connector sockets for connecting low-voltage power circuits and data transmission channels. The invention also relates to input/output electrical connectors such as audio(s) connectors and data connectors and connectors for powering electronic and electrical devices.

The known state of the art

[002] It is well known in the prior art that devices above 50 watts use two different connectors, one for power supply and one for data transfer. Another standard for connecting electronic devices up to 20 watts is the Universal Serial Bus (USB) Power Type C connector. However, its dimensions and design do not allow connecting devices with a power greater than 240 watts at the 48-volt voltage used.

[003] In European patent publication no. EP3128625 and international patent application publication no. W02006045243 discloses a USB socket with metal terminals that contact electrical contacts on the USB socket tab when a USB connector plug is inserted into the USB socket, and a base for holding the metal terminals. The metal terminals are in two groups, which can carry out standard USB signal transfer separately, and the two groups of metal terminals are placed on the opposite surfaces of the base. USB Type C connectors are designed similarly.

[004] In Taiwan Utility Model Registration Publication No. TWM614748U describes a USB Type-C positioning connector that includes an insulating housing, an insulating plate terminal assembly, and a disposable positioning element, and the insulating housing includes an upper base and a lower base formed on opposite inner sides, and the terminal assembly is located inside the insulating housing and includes a set of upper terminals formed on the upper base and a set of lower terminals formed on the lower base.

[005] In European patent applications no. EP2577813 and EP2728680 disclose a connector plug having a connector outlet having first and second opposed edges and third and fourth opposed edges extending between the first and second major edges and various electrical contacts carried by the connector outlet. The contact group includes a first set of external contacts formed on the first main side and a second set of external contacts formed on the second main side. The first group of contacts is symmetrically disposed with respect to the second group of contacts, and the output of the connector has 180 degrees of symmetry so that it can be inserted and operatively connected to the corresponding socket connector in either of the two directions of insertion. Fixation devices formed on the third and fourth sides near the distal end of the connector protrude as ground contacts.

[006] The solutions mentioned above are used to connect devices with a power of up to 240 watts at a voltage of up to 48 volts and do not separate information lines and power transmission lines, while much thinner wires are used, which do not allow connecting the necessary power. Thus, the disadvantage of the prior art is that only low-power devices can be connected.

[007] The technical problem of the invention is to create a system that allows simultaneous connection of power lines up to 1 kW, up to 2 kW and data transmission channels, while ensuring minimum size and electrical safety.

Purpose and essence of the invention

[008] The object of the invention is achieved by creating a connector comprising a connector plug and a connector socket for connecting low-voltage current circuits and data transmission channels.

The first dielectric pad is placed on one side of the ground plate, and the second dielectric pad is placed on the opposite side of the ground plate. The tab portion of the connector contains two sets of data signal terminals. Each set contains four data signal terminals, and each set is located on a corresponding dielectric pad. Each dielectric pad contains four recesses, where in each recess one of the four data signal terminals is arranged so that the data signal terminals are isolated from each other. The tab portion of the connector additionally contains four power supply terminals located at each corner of the tab portion. Each two power supply terminals are on each dielectric pad, and each power supply terminal has four sides, and two sides of each power supply terminal are covered with a dielectric pad, which isolates the power supply terminal from the ground plate and the data signal terminals. Each of the four power supply terminals is located at each of the four corners of the connector plug.

[010] The cross section of the data signal terminal is 0.5 x 0.5 mm. The cross-section of the power supply terminal is 2.5 x 4.0 mm. The thickness of the section formed by the ground plate and the first and second dielectric pads is 2.0 mm. The length of the tongue part is equal to the width of the tongue part. The width of the tongue part is 12.7 mm and the thickness of the tongue part is 7.0 mm. The ground plate extends across the width of the tongue section, dividing the tongue section into two symmetrical parts. Each said part contains one dielectric pad, one set of data signal terminals and two power supply terminals. The thickness of the protrusion of the dielectric pad between the power supply terminal and the data signal terminal is 0.6 mm.

[011] The connector socket contains a dielectric frame and a receptacle for the connector plug. The receiving opening of the connector plug has an H-shaped cross-section, which allows the insertion of a connector plug with the same H-shaped cross-section. The width of the H-shaped cross-section of the connector receiving hole is 12.7 mm and the height of the H-shaped cross-section of the connector receiving hole is 7.0 mm.

[012] The connector socket contains two ground plates. The ground plate has a rectangular cross-section. The two ground plates are placed opposite each other and built into the dielectric frame so that one of the four faces of the ground plate faces the receiving hole of the connector plug. The cross-section of the ground plate is 1.0 x 0.5 mm.

[013] The connector has four power supply terminals. The power supply terminal has a rectangular cross-section. Each power supply terminal is positioned at each corner of the connector plug receiving hole and built into the dielectric frame so that one of the four power supply terminal surfaces is exposed to the connector plug receiving hole. The cross section of the power supply terminal is 2.5 x 4.0 mm.

[014] The connector contains two sets of data signal terminals. Each set contains four data signal terminals, and the two sets of data signal terminals face each other. Each data signal terminal has a rectangular cross-section. The cross section of the data signal terminal is 0.5 x 0.5 mm. Two of the four data signal terminals per set are built into the dielectric frame so that two of the four data signal terminal faces face the receiving hole of the connector plug. Another two of the four data signal terminals per set are built into the dielectric frame so that one of the four data signal terminal surfaces faces the receiving hole of the connector plug.

[015] This connector contains a connector plug and a connector socket, allows you to connect devices to a power network up to 36 volts and data channels with one cable. It also allows you to increase the electrical power of the connected device, keeping the dimensions to a minimum and, as mentioned above, the possibility of using a single cable for connection.
