Detailed ways

The connection port integration module and the electronic device with the connection port integration module according to the preferred embodiments of the present invention will be described below with reference to related drawings, wherein the same components will be described with the same reference symbols.

2 and 3, a circuit board 4 is provided with a plurality of 3.5mm stereo jacks 41, a connection port integration module 3 and a plurality of Universal Serial Bus (hereinafter referred to as USB) connection ports 42. Signal lines (not shown) are also arranged on the circuit board 4 to electrically connect the 3.5mm stereo jack 41 , the connection port integration module 3 and the USB connection port 42 to the circuit board 4 .

In addition, the circuit board 4 can also be provided with integrated circuits or chips such as microprocessors, microcontrollers, memory, power management chips, graphics processors, transmission control chips (such as USB, IEEE 1394, ATA, IEEE 802.x ) or application-specific integrated circuits (ASICs), etc. (not shown). These integrated circuits or chips are connected to each other through the signal lines on the circuit board 4 , and can also be connected to the 3.5mm stereo jack 41 , the connection port integration module 3 and the USB connection port 42 to output the processing results or receive messages from the outside. In this embodiment, the circuit board 4 may be a motherboard of a computing device (such as a computer, a projector, a portable communication device, or a game console).

The connection port integration module 3 is disposed on the circuit board 4 , and the connection port integration module 3 includes a casing 31 , an HDMI connection port 32 and an expansion port 33 . The casing 31 can have a bottom 311 , and the casing 31 can be fixed on the circuit board 4 through the bottom 311 . In this embodiment, the HDMI connection port 32 and the expansion port 33 are parallel to each other, stacked up and down on the housing 31 , and the HDMI connection port 32 is located between the bottom 311 and the expansion port 33 .

The signal transmitted by the HDMI connection port 32 can be converted into another video standard interface for transmission by means of an interface converter 5 . In this embodiment, the video standard for converting HDMI is the DVI standard, so one end of the interface converter 5 is an HDMI transfer port 51 , and the other end is a DVI transfer port 52 .

In addition, in order to prevent the interface converter 5 connected to the HDMI connection port 32 from blocking or interfering with the adjacent connection ports, the housing 31 of the connection port integration module 3 has a width W3 that can be greater than or equal to that of the DVI transfer port 52. Width W4. When the interface converter 5 is connected to the HDMI connection port 32 of the connection port integration module 3, since the width W4 of the interface converter 5 is less than or equal to the width W3 of the connection port integration module 3, it will not block or interfere with the connection port. Stereo jack 41 and USB connection port 42 near the integration module 3 .

In addition, the settings of the HDMI connection port 32 and the expansion port 33 need to consider the frequency. In design practice, in order to avoid the attenuation of the high-frequency signal, the connection port for transmitting the high-frequency signal should be relatively close to the circuit board 4, and the connection port for transmitting the low-frequency signal should be relatively close to the circuit board 4. The connection port can be relatively far away from the circuit board 4 . Because the HDMI connection port 32 needs to transmit a large amount of video information, its signal transmission frequency is usually high frequency. In addition, with the improvement of image quality requirements, the amount of information transmission of various video specifications has also increased in recent years, making the HDMI connection port 32 signal transmission frequency is getting higher and higher. Therefore, compared with the expansion port 33, the HDMI connection port 32 can be placed closer to the circuit board 4, that is, the bottom of the connection port integration module 3, and the expansion port 33 with a lower transmission frequency is placed above the HDMI connection port 32. .

In this embodiment, since the transmission frequency of HDMI is GHz, the HDMI connection port 32 is disposed closer to the circuit board 4, and an expansion port 33 with a lower transmission frequency can be configured above the HDMI connection port 32, as shown in the figure Take the traditional VGA port as an example. However, expansion ports 33 of other standards such as D-sub terminal, IEEE 1394, IEEE 802.x, SATA, PS2, 3.5mm stereo jack, etc. can also be configured on the top of the HDMI connection port 32 . In addition, the 3.5mm stereo jack 41 and the USB connection port 42 are not limited to this specification, and expansion ports of other specifications such as D-sub terminal, IEEE 1394, IEEE 802.x, SATA, PS2, etc. should be included in this specification. within the protection scope of the invention.

As shown in FIG. 3 , the line pins 321 and 331 of the HDMI connection port 32 and the expansion port 33 can be directly extended and connected to the circuit board 4, so that the circuit on the circuit board 4 can be electrically connected (not shown). The signal on 4 can be sent to connector and/or interface converter 5 through expansion port 33.

In addition, as shown in FIG. 4A , in order to further save the space required for connecting the port integration module 3 to the circuit board 4 , in this embodiment, the two groups of line pins 331 ′, 332 ′ of the expansion port 33 ′ are respectively connected from the expansion port 33 ′. The two side surfaces 333 ′, 334 ′ of the port 33 ′ extend out in a direction parallel to the bottom 311 , and then bend down to electrically connect with the circuit board 4 .

Furthermore, another form of the extending direction of the line pins can be shown in FIG. The direction of the top surface is bent and then extended. Then the extended part exceeds the top surface of the HDMI connection port 32 and then bends down to be electrically connected with the circuit board 4 .

In addition, another form of extending the line pins 331 ′, 332 ′ of the expansion port 33 ′ can directly extend from the lower surface of the expansion port 33 ′, and extend along the HDMI connection port 32 and the housing 31 and connect with the circuit board 4 connection (not shown). Similarly, the two groups of line pins 331', 332' respectively pass through the spaces adjacent to the casing 31 on both sides of the HDMI connection port 32.

The extended forms of the above three types of line pins can reduce the thickness D of the expansion port 33' and the connection port integration module 3', and the space on both sides of the HDMI connection port 32 can also be effectively used, thereby reducing the expansion port 33'. and the area required for the connection port integration module 3 ′ on the circuit board 4 , so that the layout of the circuit board 4 can be fully utilized. The number of line pins 331', 332' can be configured according to the width d of the side of the HDMI connection port 32'. If necessary, the number of lines configured by the line pins 331', 332' can be increased to effectively reduce the number of connections. Thickness D of port integration module 3'.

As shown in FIG. 5 , it is an electronic device 8 with an integrated connection port module according to another preferred embodiment of the present invention. The electronic device 8 includes a port integration module 6 and a circuit board 7 .

The electronic device 8 in this example can be a portable electronic device, a projector, a computer or a game machine, and so on.

The connection port integration module 6 is disposed on the circuit board 7 , and the connection port integration module 6 includes a casing 61 , an HDMI connection port 62 and an expansion port 63 . The casing 61 can have a bottom 611 , and the casing 61 can be fixed on the circuit board 7 through the bottom 611 . In the connection port integration module 6, a plurality of expansion ports 63, 64 can be set above the HDMI connection port 62, such as a universal connection port, PS2, IEEE 1394, IEEE 802.x, 3.5mm stereo jack or D-sub terminal , the figure is an example of a universal connection port.

Viewed along the direction perpendicular to the bottom 611 of the casing 61 , the HDMI connection port 62 is interspersed with the expansion ports 63 , 64 , and the HDMI connection port 62 is correspondingly disposed in the space between the two expansion ports 63 , 64 .

When matching the interface converter 5 with an HDMI transfer port 51 at one end and a DVI transfer port 52 at the other end, after the HDMI transfer port 51 is connected to the HDMI connection port 62, the overall width of the interface converter 5 is just as large as the casing 61. Therefore, it will not affect the subsequent use of the adjacent 3.5mm stereo jack 71.

As shown in FIG. 6 , it is a schematic diagram of the rear of the connection port integration module 6 in FIG. 5 . The expansion ports 63, 64 each have a plurality of line pins 631, 641. The line pins 631, 641 can directly extend from the lower surface of the expansion ports 63, 64 along the housing 61 and be connected to the circuit board 4. The line pins 631 , 641 respectively pass through the spaces adjacent to the casing 61 on both sides of the HDMI connection port 62 . In this way, the space above the HDMI connection port 62 can not only be effectively used to install more expansion ports 63, 64, but the space on both sides of the HDMI connection port 62 can also be used to accommodate the line pins 631, 641 of the expansion ports 63, 64 , so the thickness D of the connection port integration module 6 can be reduced, and the layout of the circuit board 7 can be used more effectively. In addition, the variations of the line pins 631 and 641 and the line pin 621 of the HDMI connection port 62 have been described in the embodiments of FIG. 3 , FIG. 4A and FIG. 4B , so no more details are given here.
