Description

Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to a connector structure, an HDMI connector and an HDMI connector. Background Art

[0002] HDMI (High Definition Multimedia Interface) is a digital video / audio interface technology that meets the standards of the high-definition era. HDMI is currently widely used in computers, cameras, projectors, and other fields that require simultaneous video and audio transmission.

[0003] With the continuous advancement of interface connection methods, HDMI interfaces now have magnetic connections in addition to the traditional plug-in connection. The HDMI magnetic connector (also called the female connector) on the device and the magnetic connector (also called the male connector) on the HDMI cable magnetically connect, tightly fitting the female connector terminals with the male connector terminals for easy use.

[0004] For consumers, magnetic devices are not only more convenient to use but also make the device appear smarter overall. While plug-in devices are less convenient and technologically advanced than magnetic devices, they are compatible with mainstream plug-in interfaces and are therefore more adaptable. Consumers naturally want to purchase a single device that offers both connection methods: a plug-in interface for plugging in and a magnetic port for magnetic attachment.

[0005] For designers and manufacturers, understanding consumer needs is key to securing market share. Therefore, they often prefer to integrate both plug-in and magnetic connectors into devices. However, integrating both requires the width or height of two female HDMI connectors. For devices requiring a compact size, limited installation space forces them to choose between one connector type (plug-in or magnetic).

[0006] To solve this dilemma, designers and manufacturers have designed corresponding conversion connectors to convert the HDMI male connector to the HDMI magnetic female connector, or to convert the HDMI magnetic male connector to the HDMI female connector. Taking the HDMI male interface to the HDMI magnetic female interface as an example, a common structure is shown in the Chinese utility model patent number 201720018272.3, "the adapter 111 includes a plug 211 and a connecting portion 213, the plug 211 is electrically inserted into the interface 201 of the electronic device 20, the connecting portion 213 is electrically connected to the plug 211 and protrudes from the interface 201 of the electronic device 20", "the connecting portion 213 includes a first magnetic portion 2131, a first insulating portion 2135, a protective layer 2133 and at least one conductive contact 2137, the first magnetic portion 2131 is arranged around the first insulating portion 2135, the first insulating portion 2135 covers the conductive contact 2137 and insulates and isolates adjacent conductive contacts 2137 to prevent adjacent conductive contacts 2137 from being connected. There is electrical interference between them. One end of the conductive contact 2137 is exposed on the end surface of the first insulating portion 2135 away from the interface 201 and is electrically connected to the plug 211.

[0007] The HDMI female connector on the device can be connected to the HDMI male connector. The adapter can also be used to convert the HDMI female connector on the device into an HDMI magnetic female connector. Users can use a magnetic cable for magnetic connection.

[0008] Although the conversion connector can meet the user's demand for "both plug-in type and magnetic type", the disadvantages of the conversion connector are: 1) As an intermediary, the conversion connector will increase the number of connections between the device and the connection cable (from only connecting once to connecting twice), and the probability of a bad interface will increase or the interface will be more prone to bad interfaces; 2) If the conversion connector is always plugged into the device, the probability of the conversion connector being hit while plugged in will increase accordingly, which may make the connection between the conversion connector and the device's HDMI female plug-in interface more prone to bad connections; 3) There is a situation where the conversion connector may be unplugged, and it is difficult to retrieve it if it is not properly stored or stored; 4) The conversion connector is usually sold separately, and consumers need to purchase it a second time.

[0009] Therefore, using a conversion joint is not the best solution and it is necessary to make further improvements. Summary of the Invention

[0015] As a further solution of the present invention: there are two groups of the first magnets, and the two groups of first magnets are respectively close to the left edge of the HDMI female socket interface and the right edge of the HDMI female socket interface.

[0016] As a further solution of the present invention: the magnetic poles of the two groups of first magnets are arranged in opposite directions.

[0017] As a further solution of the present invention: the conductive connector corresponding to the pin for hot plug detection on the HDMI female socket interface is a hot plug detection conductive connector, and the contact head of the hot plug detection conductive connector is retracted in the plugging direction relative to the contact heads of other conductive connectors.

[0018] The present invention also provides the following technical solution: an HDMI connector, applicable to the above-mentioned HDMI connector, comprising a plug connector, wherein a side surface of the plug connector is provided with a mating area corresponding to the mounting area, the mating area being provided with a power-carrying connector corresponding one-to-one with the conductive connector, the contact head of the power-carrying connector being exposed relative to the plug connector; the mating area being provided with a second magnet corresponding to the first magnet, the magnetic pole surface of one end of the second magnet facing the outer side surface of the mating area, and when the power-carrying connector contacts the corresponding conductive connector in a one-to-one correspondence, the second magnet and the corresponding first magnet are magnetically attracted to each other.

The integrated design can avoid the disadvantages of using a conversion connector, and electrically connect the conductive connector to the pins of the female interface one by one. In fact, the PCB board used for soldering with this connector only needs to reserve a soldering position for one interface, which will not increase the cost and volume of the PCB board.

Compared with the traditional design of placing the magnetic interface and the plug-in interface side by side, the connector structure has a significantly smaller width. Compared with the traditional design of placing the magnetic interface and the plug-in interface side by side, the height is significantly reduced.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figure 1-5A connector structure is provided on a housing 100 of an application device. The housing 100 has a mounting opening 101 for mating with the female connector interface 1 of the connector. The female connector interface 1 is exposed through the mounting opening 101. The female connector interface 1 has a mating channel 11 for mating with an external male connector.

[0041] The housing 100 is provided with a mounting area 102 surrounding the periphery of the female connector 1 near the female connector 1. The mounting area 102 is provided with conductive connectors 2 corresponding one-to-one with the pins of the female connector 1. The conductive connectors 2 are electrically connected to the corresponding pins, and the contact heads of the conductive connectors 2 are exposed relative to the housing. A first magnet 3 is also provided on the mounting area 102, with one end of the first magnet 3 facing outward from the mounting area 102. The conductive connectors 2 and the first magnet 3 are collectively provided around the periphery of the female connector 1.

[0042] The conductive connector 2 and the first magnet 3 form a magnetic interface. By combining the magnetic interface and the plug-in female socket interface, only a smaller installation space needs to be added when both the plug-in type and the magnetic type are provided.

[0043] The integrated design can avoid the disadvantages of using a conversion connector and electrically connect the conductive connector 2 to the pins of the female socket interface 1 one by one. In fact, the PCB board used for soldering with this connector only needs to reserve a soldering position for an interface, which will not increase the cost and volume of the PCB board. The PCB board is usually set inside the device, which means that it will not increase the volume inside the device and is more suitable for use in micro-sized devices.

[0044] Compared with the traditional design in which the magnetic interface and the plug-in interface are placed side by side (in the width direction), this connector structure has a significantly reduced width; compared with the traditional design in which the magnetic interface and the plug-in interface are placed side by side (in the height direction), this connector structure has a significantly reduced height.

[0045] Preferably, the conductive connecting member is a probe.

[0046] The conductive connector 2 and the pins of the female connector 1 can be connected by mutual abutment or direct connection, such as welding. When the conductive connector 2 is a probe, the conductive connector 2 and the pins of the female connector 1 can also be connected by a conductive metal needle. For example, one end of the conductive metal needle is welded or abutted with the corresponding probe, and the other end of the conductive metal needle is welded to the corresponding pin of the female connector, thereby solving the problem of no direct contact point between the conductive connector 2 and the pins of the female connector 1.

[0047] See also Figure 1-5In an embodiment of the present invention, an HDMI connector includes the above-mentioned connector structure, wherein the female socket interface is an HDMI female socket interface (plug-in type).

[0048] Please refer to the following for details: Figure 1-2 The two rows of pins on the tongue plate of the HDMI female connector are the upper row of pins 12 and the lower row of pins 13. The direction of each row of pins is left and right, also known as the width direction.

[0049] Please refer to the following for details: Figure 4 All the conductive connecting members are arranged in two rows, namely a first row of conductive connecting members 21 and a second row of conductive connecting members 22 .

[0050] In the up and down direction (also called the height direction), the first row of conductive connectors 21, the upper row of pins 12, the lower row of pins 13, and the second row of conductive connectors 22 are arranged in sequence, and the first row of conductive connectors 21 are close to the upper edge of the HDMI female socket interface, and the second row of conductive connectors 22 are close to the lower edge of the HDMI female socket interface.

[0051] The first magnet 3 is close to the HDMI female socket interface in the left and right directions.

[0052] Preferably, the first magnets are provided in two groups, and the two groups of first magnets (3a, 3b) are respectively close to the left edge of the HDMI female socket interface and the right edge of the HDMI female socket interface.

[0053] More preferably, the magnetic poles of the two sets of first magnets are arranged in opposite directions. That is, the magnetic pole surface of the first magnet 3a facing the outside of the installation area 102 is the north pole, and the magnetic pole surface of the first magnet 3b facing the outside of the installation area 102 is the south pole; or the magnetic pole surface of the first magnet 3a facing the outside of the installation area 102 is the south pole, and the magnetic pole surface of the first magnet 3b facing the outside of the installation area 102 is the north pole.

[0054] Furthermore, the conductive connector corresponding to the pin for hot plug detection on the HDMI female socket interface is a hot plug detection conductive connector 2a, and the contact head of the hot plug detection conductive connector 2a is retracted in the plugging direction relative to the contact heads of other conductive connectors.

[0055] Because the conductive connector is electrically connected to the pins of the HDMI female connector, improvements to a specific conductive connector (hot-plug detection conductive connector 2a) enable hot-plug detection functionality for the magnetic connector. This simplifies the circuit design by requiring only one set of hot-plug detection circuitry, allowing both the plug-in connector and the magnetic connector to share the same hot-plug detection circuitry.

[0056] See also Figure 1-6In an embodiment of the present invention, an HDMI connector is provided. The HDMI connector may be part of an HDMI data cable and used in conjunction with the aforementioned HDMI connector. Therefore, an HDMI data cable having at least one HDMI connector is also provided.

[0057] The HDMI connector includes a plug connector 400, a side of which is provided with a mating area 200 corresponding to the mounting area 102, and the mating area 200 is provided with a power connection member 201 corresponding one-to-one to the conductive connection member 2, and the contact head of the power connection member 201 is exposed relative to the plug connector 400.

[0058] A second magnet 202 corresponding to the first magnet 3 is also mounted on the mating area 200, with one end of the second magnet 202 having a magnetic pole facing the outer side of the mating area 200. When the energized connectors 201 are in one-to-one contact with the corresponding conductive connectors 2, the second magnet 202 and the corresponding first magnet 3 are magnetically attracted to each other.

[0059] When there are two groups of the first magnets, the two groups of first magnets are respectively close to the left edge of the HDMI female socket interface and the right edge of the HDMI female socket interface, and the magnetic poles of the two groups of first magnets are arranged in opposite directions: the two groups of first magnets are also used to determine the engagement direction, that is, the HDMI connector can only maintain forward engagement and cannot be reversed.

[0060] When the user uses the reverse plug connector to connect (the positions of the two sets of second magnets are swapped), the first magnet and the non-corresponding second magnet will produce a repulsive effect, which is mainly manifested as difficulty in approaching each other, and they will not stay close after approaching or will automatically separate after releasing. The user can promptly determine that it is reverse insertion based on the above situation.

[0061] Preferably, a positioning area 300 corresponding to the HDMI female connector is further provided on a side surface of the plug connector 400 corresponding to the installation area 102. The positioning area 300 is formed with a positioning column 301 that cooperates with the plug channel 11 of the HDMI female connector.

[0062] By properly utilizing the shape of the HDMI female connector's insertion channel 11, the positioning pin 301 is oriented to ensure that the conductive connector 2 accurately contacts the corresponding energized connector 201. With this positioning function, there's no need for a separate positioning slot. By directly utilizing the HDMI female connector's insertion channel, no additional design is required, whether in width, height, or depth.

[0063] More preferably, a guiding inclined surface is formed on the front end of the positioning post, so that the positioning post can enter the insertion channel more easily.

[0064] The dimensions of the hot plug detection conductive connector 2a should be designed so that, when the positioning post 301 protrudes into the insertion channel 11 of the HDMI female connector, the hot plug detection conductive connector 2a is the last to contact the corresponding female connector pin. The dimensions of the hot plug detection conductive connector 2a should be designed so that, when the positioning post 301 exits the insertion channel 11 of the HDMI female connector, the hot plug detection conductive connector 2a is the first to separate from the corresponding female connector pin.

[0065] For example, when the portion of the positioning post 301 close to the guide bevel 302 enters the insertion channel 11, the distance between the hot plug detection conductive connector 2a and the corresponding pin does not meet the contact between the two, while the distance between other conductive connectors and the corresponding pins meets the contact; and when the portion of the positioning post 30 away from the guide bevel 302 enters the insertion channel 11, the distance between the hot plug detection conductive connector 2a and the corresponding pin meets the contact between the two.

[0066] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
