Description

Technical Field

[0001] The invention relates to the technical field of an OPS host, and in particular to a device for facilitating the connection between an OPS host and an interface. Background Art

[0002] OPS hosts are widely used in many scenarios such as modern multimedia teaching, commercial exhibitions, and smart conferences. As a standardized modular computer, OPS hosts need to be frequently connected to various external device interfaces. In order to facilitate the connection between OPS hosts and external devices, some new OPS computer adapter boards have appeared on the market.

[0003] For example, a Chinese patent with publication number CN220232377U discloses an OPS computer adapter board, including an adapter board body, a computer host docked with the adapter board body, and a protective mechanism arranged on the outside of the adapter board body, wherein the protective mechanism includes a protective cover arranged on the outside of the adapter board body, and the inner wall of the protective cover close to the computer host is provided with a plug interface that matches the adapter board body, and a cover plate is detachably installed on the top of the protective cover, and the inner walls on both sides of the protective cover are respectively provided with multiple groups of heat dissipation ports. This scheme can protect the adapter board body during use and carrying of the adapter board body by providing a protective mechanism, and the cooperation of the protective cover and the cover plate in the protective mechanism, and can facilitate heat dissipation of the adapter board body by providing heat dissipation ports on both sides of the protective cover and supporting the adapter board body through a hollow plate.

[0004] The OPS computer adapter board provided by the above patent is mainly used to protect the exposed interfaces on the adapter board to prevent the interfaces from being easily damaged due to long-term exposure. The adapter board of this structure is mainly used to provide more expansion interfaces, while the actual OPS host is mostly connected to the following interfaces: Figure 1 The OPS host shown in the figure is similar. The adapter plug of this type of OPS host is fixed on the OPS motherboard. When in use, you only need to plug the adapter plug into the corresponding external device, and the motherboard without the adapter plug cannot be normally connected to the external device; however, since the adapter plug is fixed on the OPS motherboard, each adapter plug can only correspond to one OPS motherboard.

[0060] Working principle: When in use, assemble the entire connection device according to the use requirements, then plug the adapter plug 17 into the external device that matches the OPS host, and then use the VGA connection line 2, HDMI connection line 3 and power connection line 4 to connect the adapter PCB board 1 to the computer motherboard that meets the use requirements, so that the role of the OPS host can be brought into play. When it is necessary to replace the computer motherboard of other models, you only need to unplug the end of the VGA connection line 2, HDMI connection line 3 and power connection line 4 connected to the computer motherboard, and connect it to the new computer motherboard for use. The operation is simple and convenient. It has high flexibility in use and a wide range of applications. In addition, during the operation of the entire connection device, the heat generated will be drawn away by the cooling fan 7, and the connection component 9 can also be used to stably press the adapter plug 17 on the plug interface of the housing 5 device, ensuring the stability of the use of the entire connection device.

[0061] In summary, compared with the prior art, the present application sets a transfer PCB board 1, and installs the transfer plug 17 of the traditional OPS host on the transfer PCB board 1. The transfer PCB board 1 can simultaneously connect multiple connection lines such as VGA connection line 2, audio connection line and HDMI connection line 3, and the PCB board can be connected to a variety of different computer motherboards through these connection lines. When the motherboard of the OPS host cannot meet the use requirements, a computer motherboard that meets the use requirements can be found, connected to the transfer PCB board 1 through various connection lines, and the transfer plug 17 on the transfer PCB board 1 can be plugged into the corresponding external device to use the connected computer motherboard. It effectively avoids the problem that the transfer plug 17 of the traditional OPS motherboard can only be used in conjunction with the OPS motherboard connected thereto, and greatly improves the use flexibility of the entire connection device.
