Description

USRP outer casing cover

Technical Field

The utility model belongs to the technical field of radio communication, a USRP outer clamshell is related to.

Background

Radio devices communicate by receiving or transmitting electromagnetic waves, however, radio devices also generate EMI due to electromagnetic effects, so many radio devices subject their surrounding radio devices to electromagnetic interference or are exposed to EMI from the surrounding environment. This is particularly true for universal software radio equipment (USRP). The USRP equipment is developed by a Matt Ettus-led team, and is intended to become a software radio platform with wide application, and the EMI resistance of the USRP equipment is poor. In order to reduce the occurrence of EMI phenomena, USRP radios need to be correspondingly electromagnetically shielded. At present, radio equipment is usually placed in a shell body which is protected by electromagnetic interference, but the shell body usually has only one layer of electromagnetic interference protection plate, and not only the structural strength is poor, but also the electromagnetic protection capability is limited.

Disclosure of Invention

In order to solve the problem, the utility model provides a USRP outer cover, its technical scheme as follows:

a USRP enclosure cover comprising: the diamagnetic body is provided with a plurality of diamagnetic bodies which are uniformly distributed on the surface of the outer shell, and a diamagnetic gap is reserved between every two adjacent diamagnetic bodies.

The utility model provides a technical scheme includes following beneficial effect at least:

the utility model provides a USRP outer clamshell through setting up diamagnetic body, can resist outside electromagnetic interference effectively, and diamagnetic body can also play certain radiating action simultaneously.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

In the present invention, unless otherwise expressly specified or limited, the term "disposed" is to be understood in a broad sense and can be either a static connection or a dynamic connection, a non-removable connection or a removable connection, or resting thereon or in a particular orientation; the fixed connection and the installation connection are static connection; the sleeve joint can be a sleeve joint which is sleeved outside a certain part without contacting, a sleeve joint which is sleeved outside the certain part and is in threaded connection with the certain part, or a sleeve joint which is sleeved outside the certain part and is in detachable connection; "threaded connection" means a connection by thread engagement, rotation; "rotationally connected" means connected by balls, rollers, etc., and one or both of the two connectors can rotate; the term "transmission connection" refers to a connection mode that is indirectly connected by means of a chain, a conveyor belt or a connecting rod and acts synchronously; "communicate" means "fixed" or "connected" together and the internal spaces are in communication; "elastic connection" means that the connection is realized by a spring, a spring sheet or other components capable of generating deformation; "electrically connected" means that the electronic components are connected by a conductive medium; unless otherwise specifically defined, the specific meanings of the above terms in the present invention can be understood by those of ordinary skill in the art according to specific situations.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention. In the description of the present invention, it is to be understood that the terms "first", "second", "third", "fourth", "fifth", and the like are used merely for distinguishing between descriptions and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. are used to indicate an orientation or positional relationship based on that shown in the drawings, it is only for convenience of description and simplicity of description, and it is not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Referring to fig. 1, a USRP housing cover includes: the diamagnetic body comprises an inner shell body 1, an outer shell body 2 attached to the inner shell body 1, and diamagnetic bodies 3 extending from the outer shell body 2, wherein the diamagnetic bodies 3 are uniformly distributed on the surface of the outer shell body 2, and diamagnetic gaps 30 are reserved between every two adjacent diamagnetic bodies 3.

Specifically, the diamagnetic body 3 is made of medium and low frequency magnetic shielding materials. For example, the section bar made of aluminum or zinc, the back surface of the section bar made of aluminum or zinc is plated with alloy soft magnetic material, the back surface of the section bar made of aluminum or zinc is plated with amorphous soft magnetic alloy material, etc.

Specifically, the side length of the cross section of the diamagnetic body 3, which is far away from the surface of the outer shell 2, is greater than the side length of the cross section of the diamagnetic body 3, which is connected with the surface of the outer shell 2. In this way, the diamagnetic body 3 is made more resistant to interference. Meanwhile, the heat dissipation area of the diamagnetic body 3 can be increased.

In a further implementation manner, the USRP outer cover provided by the embodiment of the present invention further includes a carbon fiber layer 4 disposed between the diamagnetic gap 30, and the carbon fiber layer 4 is connected with the diamagnetic body 3 to support the diamagnetic body 3. The carbon fibre layers 4 may also extend onto the inner shell 1.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
