Description

Technical Field

[0001] This invention belongs to the field of TEM chamber assembly technology, specifically, it relates to an assembly method for a concentric cone TEM chamber. Background Technology

[0002] Field strength is one of the basic parameters of radio waves. The calibration accuracy of the field strength parameter directly affects the accuracy of the field strength measurement results. Internationally, methods such as the TEM chamber method, the GTEM chamber method, and the standard field method based on a pyramidal horn antenna are commonly used to calibrate the field strength.

[0003] Currently, the concentric cone TEM chamber broadband field strength calibration system is generally considered to be the system capable of generating broadband electromagnetic fields, as it can meet the full-band, broadband frequency sweep calibration requirements of field strength probes. To ensure sufficient testing area within the concentric cone TEM chamber, these chambers are typically designed to be relatively tall and heavy, and are manufactured in sections. How to assemble and precisely position these sections is a pressing issue that needs to be addressed during the development of the concentric cone TEM chamber. Summary of the Invention

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and are not to a precise scale, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0032] It should be noted that, in order to clearly illustrate the content of this invention, several embodiments are provided to further explain different implementations of the invention. These embodiments are enumerated rather than exhaustive. Furthermore, for the sake of brevity, content mentioned in the preceding embodiments is often omitted in the following embodiments. Therefore, content not mentioned in the later embodiments can be referred to in the preceding embodiments.

[0033] See Figures 1 to 6 As shown, according to an embodiment of this application, a method for assembling a concentric cone TEM chamber is provided, which is used to assemble the concentric cone TEM chamber.

[0034] Specifically, the concentric cone TEM chamber in this embodiment includes an outer cone 10, an inner cone 20, a support 30, a load terminal 40, a load terminal clamping block 50, a microwave absorbing material 60, and a connector 70. The inner cone 20 is installed inside the outer cone 10. The support 30 is supported between the outer wall of the inner cone 20 and the inner wall of the outer cone 10. The load terminal 40 is located at the top of the inner cone 20 and connected to it via the load terminal clamping block 50. The microwave absorbing material 60 is located at the top of the load terminal 40. The connector 70 connects the inner cone 20 and the bottom of the outer cone 10.

[0035] Further, in this embodiment, the outer cone 10 includes a top outer cone segment 110, a first outer cone segment 11, a second outer cone segment 12, a third outer cone segment 13, a fourth outer cone segment 14, a fifth outer cone segment 15, a sixth outer cone segment 16, a seventh outer cone segment 17, and an outer cone tip 18, connected sequentially from its top to its bottom. The inner cone 20 includes a first inner cone segment 21, a second inner cone segment 22, a third inner cone segment 23, and an inner cone tip 24, connected sequentially from its top to its bottom. It is understood that the top and bottom ends mentioned in this embodiment refer to the top and bottom ends of the outer cone 10 and the inner cone 20 when in use, such as... Figure 1 As shown in the figure, the end facing upwards is the top, and the end facing downwards is the bottom.

[0036] The support body 30 includes a first support body 31, a second support body 32, a third support body 33, a fourth support body 34, and a fifth support body 35. Through the action of the first support body 31, the second support body 32, the third support body 33, the fourth support body 34, and the fifth support body 35, the inner cone 20 can be stably supported inside the outer cone 10.

[0037] See Figures 1 to 7 As shown, in order to assemble the concentric cone TEM chamber described above, the assembly method of the concentric cone TEM chamber provided in this application embodiment includes the following steps:

[0038] Step S1: Assemble the first outer conical section 11, the second outer conical section 12, the load terminal 40, the load terminal pressure block 50, and the first inner conical section 21 in sequence. If the lower end stop plane of the first inner conical section 21 is coplanar with the lower end stop plane of the second outer conical section 12, and the upper end stop plane of the upper end face of the load terminal 40 is coplanar with the upper end stop plane of the first outer conical section 11, then proceed to the next step; otherwise, check for error sources and rework.

[0039] In this step, the first outer conical segment 11 is first placed on the bracket 80. The bracket 80 supports the first outer conical segment 11, facilitating the assembly of subsequent parts. During the placement of the first outer conical segment 11, it is necessary to ensure that the axial direction of the first outer conical segment 11 is consistent with the height direction of the bracket 80. After the first outer conical segment 11 is placed, the second outer conical segment 12, the load terminal 40, the load terminal pressure block 50, and the first inner conical segment 21 are assembled in sequence.

[0040] In this step, the second outer cone section 12 and the first outer cone section 11 are connected by a connecting flange 101 disposed on the outer periphery of both. Specifically, the two are connected by bolts 90 passing through the connecting flange 101. The load terminal 40 is located inside the first outer cone section 11 and rests on the inner wall surface of the first outer cone section 11. The load terminal pressure block 50 is threadedly connected between the load terminal 40 and the first inner cone section 21.

[0041] In step S1, after assembling the first inner cone segment 21, the top outer cone segment 110 is connected to the first outer cone segment 11, and the absorbing material 60 is assembled on the top of the load terminal 40.

[0042] In this step, a plane instrument or similar device can be used to check whether the lower end stop plane of the first inner cone segment 21 and the lower end stop plane of the second outer cone segment 12 are coplanar.

[0043] Step S2: Assemble the second inner cone segment 22, the first support 31, the third outer cone segment 13, the second support 32, and the fourth outer cone segment 14 in sequence. If the upper end stop plane of the second inner cone segment 22, the upper end stop plane of the third outer cone segment 13, and the top surface of the first support 31 are coplanar, and the lower end stop plane of the second inner cone segment 22, the bottom surface of the second support 32, and the bottom surface of the fourth outer cone segment 14 are coplanar, then proceed to the next step; otherwise, detect the error source and rework.

[0044] In step S2, the second inner cone segment 22 is first connected to the first inner cone segment 21, and the second inner cone segment 22 and the first inner cone segment 21 are connected by threads. After the second inner cone segment 22 is connected to the first inner cone segment 21, the first support body 31, the third outer cone segment 13, the second support body 32 and the fourth outer cone segment 14 are assembled in sequence.

[0045] In this step, a planarity tester or similar instrument can be used to check whether the upper end stop plane of the second inner cone segment 22, the upper end stop plane of the third outer cone segment 13, and the top surface of the first support 31 are coplanar, as well as whether the lower end stop plane of the second inner cone segment 22, the bottom surface of the second support 32, and the bottom surface of the fourth outer cone segment 14 are coplanar.

[0046] Step S3: Assemble the third inner cone segment 23, the third support 33, the fifth outer cone segment 15, the fourth support 34, and the sixth outer cone segment 16 in sequence. If the upper end stop plane of the third inner cone segment 23, the upper end stop plane of the fifth outer cone segment 15, and the top surface of the third support 33 are coplanar, and the lower end stop plane of the third inner cone segment 23, the lower end stop plane of the sixth outer cone segment 16, and the lower end stop plane of the fourth support 34 are coplanar, then proceed to the next step; otherwise, detect the error source and rework.

[0047] In step S3, the third inner cone segment 23 is first connected to the second inner cone segment 22, and the third inner cone segment 23 and the second inner cone segment 22 are connected by threads. After the third inner cone segment 23 and the second inner cone segment 22 are connected, the third support body 33, the fifth outer cone segment 15, the fourth support body 34 and the sixth outer cone segment 16 are assembled in sequence.

[0048] In this step, a plane instrument or similar device can be used to check whether the upper end stop plane of the third inner cone segment 23, the upper end stop plane of the fifth outer cone segment 15, and the top surface of the third support 33 are coplanar, as well as whether the lower end stop plane of the third inner cone segment 23, the lower end stop plane of the sixth outer cone segment 16, and the lower end stop plane of the fourth support 34 are coplanar.

[0049] Step S4: Assemble the inner cone tip 24, the fifth support body 35, the seventh outer cone segment 17, the outer cone tip 18, and the connector 70 in sequence. If the top stop plane of the inner cone tip 24, the top surface of the fifth support body 35, and the top stop plane of the seventh outer cone segment 17 are coplanar, the assembly of the concentric cone TEM chamber is completed; otherwise, the source of detection error will be returned for repair.

[0050] In step S4, the inner cone tip 24 is connected to the third inner cone section 23 by a threaded connection. After connecting the inner cone tip 24, the fifth support body 35, the seventh outer cone section 17, the outer cone tip 18, and the connector 70 are assembled in sequence.

[0051] In this step, a planimeter or similar instrument can be used to check whether the top stop plane of the inner cone tip 24, the top surface of the fifth support 35, and the top stop plane of the seventh outer cone segment 17 are coplanar.

[0052] During actual assembly, connecting flanges 101 are provided on the first outer conical section 11, the second outer conical section 12, the third outer conical section 13, the fourth outer conical section 14, the fifth outer conical section 15, the sixth outer conical section 16, the seventh outer conical section 17, and the outer conical tip 18. Adjacent pairs of the first outer conical section 11, the second outer conical section 12, the third outer conical section 13, the fourth outer conical section 14, the fifth outer conical section 15, the sixth outer conical section 16, the seventh outer conical section 17, and the outer conical tip 18 are connected by these connecting flanges 101. Adjacent pairs of the first outer conical section 11, the second outer conical section 12, the third outer conical section 13, the fourth outer conical section 14, the fifth outer conical section 15, the sixth outer conical section 16, the seventh outer conical section 17, and the outer conical tip 18 are connected by bolts 90 passing through the connecting flanges 101.

[0053] The first inner cone section 21, the second inner cone section 22, and the third inner cone section 23 are connected by threads between adjacent sections.

[0054] Optionally, in this embodiment, the first support 31, the second support 32, the third support 33, the fourth support 34, and the fifth support 35 are all annular foam supports.

[0055] This method is based on the mating surface of the stop and adopts a segmented installation method for the concentric cone TEM chamber. During assembly, the assembly error is monitored in real time, thereby achieving the purpose of precise positioning.

[0056] As can be seen from the above description, the embodiments of this application achieve the following technical effects:

[0057] 1. The assembly method of the concentric cone TEM chamber of the present invention solves the problem of assembling the concentric cone TEM chamber.

[0058] 2. The assembly method of the concentric cone TEM chamber of the present invention can monitor the assembly accuracy in real time, locate the error source, and improve the assembly accuracy of the concentric cone TEM chamber.

[0059] 3. The assembly method of the concentric cone TEM chamber of the present invention is simple, easy to implement, and highly operable.

[0060] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0061] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
