Description

Technical Field

[0001] The utility model relates to the technical field of bus interfaces, and in particular to a double-layer M.2 interface connector. Background Art

[0002] Many computer motherboards are now equipped with wireless network connectors, typically using an M.2 interface, which connects to wireless network cards and other devices. There are two common communication protocols: PCIE bus and CNVI bus, both of which have relatively fixed routing definitions. This fixed routing leaves some unused pins on the M.2 connector. Desktop computers typically connect the 80port debug output cable to these unused pins, allowing them to retrieve debug information using a digital diagnostic card.

[0003] However, the current M.2 interface connector cannot support the simultaneous use of a wireless network card and a digital diagnostic card. For example, when using a digital diagnostic card to obtain debugging information, the wireless network card cannot be inserted at the same time to troubleshoot wireless network-related issues. In other words, it cannot meet the needs of both a wireless network card and a digital diagnostic card. Utility Model Content

DETAILED DESCRIPTION

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are 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 those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal connections between two components; they may refer to wireless connections or wired connections. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Reference Figure 1 As shown in the figure, it is a standard M.2 interface, which meets the principle diagram of the wireless chip of the PCIe bus standard. It can be seen that there are many idle pins. Therefore, the 80port debug line of the desktop can be connected to these idle pins. Figure 2 As shown, the 80port debug information is output to the digital diagnostic card to view and diagnose the computer status and error codes in real time.

[0035] The current M.2 connector has limited interfaces and restricted locations, so only wireless network cards or digital diagnostic cards can be used alone. This leads to two problems: one is that the wireless network card cannot be inserted during debugging to eliminate problems related to the wireless network card; the other is that the needs of both the wireless network card and the digital diagnostic card cannot be met at the time of production and shipment.

[0036] In view of this, a double-layer M.2 interface connector is provided in this embodiment, which can be used to insert a wireless network card or a digital diagnostic card, etc. Figure 3 2 is a structural diagram of a double-layer M.2 interface connector according to an embodiment of the present invention, including a connector body 1, a first plug interface 11, and a second plug interface 14, as described below.

[0037] Reference Figure 4 As shown, the connector body 1 has input connection contacts 21 and output connection contacts 22 at the bottom for connecting to an external motherboard. The external motherboard can be a motherboard on a terminal device such as a laptop or desktop computer. The external motherboard can be electrically connected to the double-layer M.2 interface connector through the connection contacts to achieve data exchange. Figure 2 As shown, each pin with signal input on the wireless chip corresponds to an input connection contact 21 , and each pin with signal output corresponds to an output connection contact 22 .

[0038] The first plug interface 11 is provided on the connector body 1, referring to Figure 5 As shown, the first plug interface 11 is provided with a first terminal 111, which is connected to the input connection contact 21 via the first conductor 12. The first plug interface 11 is provided with multiple first terminals 111, all of which are arranged in an array, and each first terminal 111 is connected to a corresponding input connection contact 21 via a first conductor 12. In addition, the first plug interface 11 is also provided with multiple second terminals 112, each of which is connected to a corresponding output connection contact 22 via a second conductor 13. The first conductors 12 and the second conductors 13 can be wires or conductive copper sheets, etc.

[0039] In some optional implementations, the first plug-in interface 11 is used to plug into a wireless network card. When the first plug-in interface 11 is plugged into the wireless network card, fast data exchange can be achieved between the wireless network card and the motherboard, and high-bandwidth communication can be achieved through the PCIe protocol.

[0040] The second plug interface 14 is provided on the connector body 1 and above the first plug interface 11. A third terminal 141 is provided within the second plug interface 14. The third terminal 141 is connected to the input connection contact 21 via a 12th-first conductive body. Multiple third terminals 141 are provided within the second plug interface 14. All third terminals 141 are arranged in an array, and each third terminal 141 is connected to a corresponding input connection contact 21 via a 12th-first conductive body.

[0041] In some optional embodiments, the second plug interface 14 is used for plugging with a digital diagnostic card. When the second plug interface 14 is plugged with the digital diagnostic card, the error code or status information of the mainboard can be read and displayed, which helps to diagnose hardware problems.

[0042] In this embodiment, referring to Figure 3 As shown, the first plug interface 11 is used for plugging with a wireless network card, and the second plug interface 14 is used for plugging with a digital diagnostic card.

[0043] The double-layer M.2 interface connector provided in this embodiment includes two plug-in interfaces arranged upper and lower, which can be used to plug in a wireless network card alone, or a wireless network card and a digital diagnostic card at the same time. Only one M.2 interface connector can meet the functions of both the wireless network card and the digital diagnostic card, which has high flexibility.

[0044] Reference Figure 4 As shown, in some optional embodiments, the second conductor 13 is arranged below the first plug interface 11, and the second conductor 13 extends from the output connection contact 22 to the first plug interface 11, one end of the second conductor 13 is connected to the output connection contact 22, and the other end of the second conductor 13 is connected to the second terminal 112.

[0045] Reference Figure 6 As shown, in some optional embodiments, the first conductor 12 includes a first sub-conductor 121 and a second sub-conductor 122. The first sub-conductor 121 and the second sub-conductor 122 are arranged behind the second conductor 13. The first sub-conductor 121 extends from the input connection contact 21 to the first plug interface 11. One end of the first sub-conductor 121 is connected to the input connection contact 21, and the other end of the first sub-conductor 121 is connected to the first terminal 111. That is, the first conductor 12 is arranged in the back row, and the second conductor 12 is arranged in the front row.

[0046] In some optional embodiments, the second sub-conductor 122 extends from the input connection contact 21 to the second plug interface 14 , one end of the second sub-conductor 122 is connected to the input connection contact 21 , and the other end of the second sub-conductor 122 is connected to the third terminal 141 .

[0047] In some related technologies, M.2 interface connectors often have only one plug port, that is, only one row of pins. Based on this, only a wireless network card or digital diagnostic card can be inserted. Although there are still vacant pins, due to the limited space, other cards cannot be inserted. Moreover, if more pins are added to the single plug port, they will be affected by the space below and cannot be extended from the front row of pins. Therefore, in this embodiment, the leads corresponding to the vacant terminals are extended from the rear of the connector and extended in the direction of the second plug port to form a second plug port.

[0048] This embodiment fully utilizes the wireless network connector, specifically the idle pins on the wireless chip, by staggering the idle pins, effectively enabling the simultaneous use of a wireless network card and a digital diagnostic card. It also effectively utilizes the space available on the M.2 interface connector, minimizing its size.

[0049] In some optional embodiments, the first sub-conductors 121 and the second sub-conductors 122 are arranged at intervals along the length direction of the connector body 1. Figure 6 As shown, the first conductor 12 and the second conductor 13 are spaced apart in the same direction, making reasonable use of the idle pins on the M.2 interface connector so that one connector can simultaneously realize two functions.

[0050] Reference Figure 3 As shown, in some optional embodiments, the connector body 1 includes:

[0051] The barrier structure 15 is provided in the width direction of the connector body 1 and extends from the front to the rear of the connector body 1 to separate the first plug interface 11 from the second plug interface 14 .

[0052] Since the metal contact points of general wireless network cards and digital diagnostic cards are separated, refer to Figure 7 As shown, therefore, in this embodiment, providing a barrier structure 15 on the connector body 1 can effectively improve the convenience of plugging the wireless network card and the digital diagnostic card.

[0053] In some optional embodiments, a window 16 is further provided on the connector body 1, which can help dissipate heat and effectively reduce the impact of overheating on components.

[0054] In some optional embodiments, one end of the first sub-conductor 121 is welded to the first terminal 111, and the other end of the first sub-conductor 121 is welded to the input connection contact 21. One end of the second sub-conductor 122 is welded to the third terminal 141, and the other end of the second sub-conductor 122 is welded to the input connection contact 21. One end of the second conductor 13 is welded to the second terminal 112, and the other end of the second conductor is welded to the output connection contact 22.

[0055] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
