Description

TECHNICAL FIELD

[0001] The present application relates to the connection of board-to-board joints in a high-frequency active module, and in particular to a joint-to-joint connection mechanism between the board-to-board joints. BACKGROUND

[0002] In the prior art, a high-frequency active module includes printed circuit boards and board-to-board (BTB) joints and other electronic devices disposed on the circuit boards. When mass producing such high-frequency active modules, the functions and performance of the high-frequency active module need to be tested, otherwise when the high-frequency active module has quality problems, the cost of repair is high. In the traditional testing method for high-frequency active modules, the board-to-board joints of the high-frequency active module are directly connected with the board-to-board joints of a test board. Although this connection method can use the test board to test the high-frequency active module, it is likely to damage the board-to-board joints of the high-frequency active module and the board-to-board joints of the test board, affecting the testing effect of the functions and performance of the high-frequency active module. Moreover, this direct connection method is low in efficiency and is not suitable for mass testing.

[0003] In order to overcome the shortcomings of the above testing method, in an improved testing method for high-frequency active modules, as shown in Figure 1A and Figure 1B , a joint-to-joint connection mechanism including an elastic measurement needle assembly 31 is used, which makes the pins of the board-to-board joints (first joint 1) of the test board and the board-to-board joints (second joint 2) of the high-frequency active module realize signal communication, thereby transmitting high-frequency signals, control signals, electrical signals, and clock signals, etc. This connection method overcomes the shortcomings of the above-mentioned traditional connection method of the joints. However, the following two factors need to be considered, one is that the first needle assembly 31a for transmitting high-frequency signals needs to be effectively isolated, and the other is that the transmission of high-frequency signals through the first needle assembly 31a needs to ensure port matching performance and avoid excessive insertion loss. When designing the pins of the board-to-board joints for the above two factors, in order to increase the isolation, the following typical design is usually used, that is, a ground pin is designed on both sides of the high-frequency signal pin in a row of pins. Correspondingly, in the joint-to-joint connection mechanism, as shown in Figure 1B , the first needle assembly 31a for transmitting high-frequency signals has a second needle assembly 31b for grounding on both sides. Thus, as shown in Figure 1C , the field of high-frequency signal transmission of the first needle assembly 31a is constrained by the grounded second needle assembly 31b on both sides, thereby ensuring the isolation of the first needle assembly 31a. However, when the number of pins is limited and the above-mentioned typical design cannot be realized, the high-frequency signal pin is usually allocated to the edge pin of the row of pins of the board-to-board joint. In this case, as shown in Figure 1BAs shown, there are asymmetric ground pin assemblies (i.e., the second pin assembly 31b and the third pin assembly 31c) on both sides of the first pin assembly 31a corresponding to the high-frequency signal pin, and the asymmetric structure layout of the ground pin assemblies will adversely affect the port matching performance and insertion loss when the high-frequency signal is transmitted in the first pin assembly 31a. SUMMARY

[0055] Various exemplary embodiments, features and aspects of the present application will be explained in detail below with reference to the accompanying drawings. Like reference numerals in the drawings denote like or similar elements. Although various aspects of the embodiments are illustrated in the drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0056] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0057] In addition, for a better understanding of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art will understand that the present application can also be implemented without some specific details. In some examples, methods, means, elements well known to those skilled in the art are not described in detail in order to highlight the main ideas of the present application.

[0058] The structure of the inter-joint connection mechanism according to the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0059] Inter-joint connection mechanism (according to the first embodiment of the present application)

[0060] As shown in Figures 2A to 2C , the inter-joint connection mechanism 3 according to the first embodiment of the present application can be used for signal transmission between the pins of both the two plate-to-plate joints (the first joint 1 and the second joint 2), and the inter-joint connection mechanism 3 can transmit high-frequency signals, control signals, electrical signals, clock signals, etc. Specifically, in the present embodiment, the inter-joint connection mechanism 3 includes elastic measurement needle assemblies 31, a shielding device 32, and a support structure (including a cover 33 and a base 34).

[0061] In the present embodiment, as shown in Figures 2A to 2C , the extension directions of all the elastic measurement needle assemblies 31 are the same and parallel to each other, and two adjacent elastic measurement needle assemblies 31 are spaced apart by a certain distance. Each elastic measurement needle assembly 31 is used to contact the pins of the first joint 1 and the second joint 2, and the signals transmitted in each elastic measurement needle assembly 31 are different according to the different pins of the two joints 1, 2. Each elastic measurement needle assembly 31 includes a conductive material, such as Figure 2EAs shown, each elastic measuring needle assembly 31 includes a cylindrical portion 311, a spring (not shown), a first plunger 312, and a second plunger 313 assembled together. The cylindrical portion 311 is generally cylindrical in shape and has a generally cylindrical internal storage space. The spring is, for example, a cylindrical helical spring, and is housed within the storage space of the cylindrical portion 311. The first plunger 312 and the second plunger 313 are located at opposite ends of the spring. One end of the first plunger 312 is always housed within the cylindrical portion 311 and abuts against one end of the spring, while the other end of the first plunger 312 extends out of the cylindrical portion 311. One end of the second plunger 313 is always housed within the cylindrical portion 311 and abuts against the other end of the spring, while the other end of the second plunger 313 extends out of the cylindrical portion 311. Both the first plunger 312 and the second plunger 313 are capable of relative movement with respect to the cylindrical portion 311 along the axial direction of the cylindrical portion 311. Thus, when the pin of the first connector 1 abuts against the other end of the first plunger 312, one end of the first plunger 312 can apply a force to the spring, and the spring force generated by the spring can ensure reliable contact between the pin of the first connector 1 and the other end of the first plunger 312. Similarly, the spring force can also ensure reliable contact between the pin of the second connector 2 and the other end of the second plunger 313.

[0062] In the first connector 1 and the second connector 2, one edge pin in a row of pins is assigned as a high-frequency signal pin, resulting in an asymmetrical structural layout of the ground pins on both sides of this high-frequency signal pin. Correspondingly, as... Figures 2B to 2D As shown, in this embodiment, the elastic measuring pin assembly 31 corresponding to the high-frequency signal pin is the first pin assembly 31a, which transmits the high-frequency signal. The elastic measuring pin assemblies 31 on both sides of the first pin assembly 31a, used for connecting to the ground pin, are the second pin assembly 31b and the third pin assembly 31c, which are used for grounding. The first pin assembly 31a and the second pin assembly 31b are located in a row of elastic measuring pin assemblies 31. The arrangement direction D1 of the first pin assembly 31a and the second pin assembly 31b is consistent with the arrangement direction of the row of elastic measuring pin assemblies 31 and perpendicular to the extension direction of the first pin assembly 31a and the second pin assembly 31b. In this arrangement direction D1, the second pin assembly 31b is located on one side of the first pin assembly 31a, and the third pin assembly 31c is located on the other side of the first pin assembly 31a. Furthermore, in the alignment direction D2, which is perpendicular to the aforementioned extension direction and the aforementioned arrangement direction D1, the first needle assembly 31a and the second needle assembly 31b are aligned (that is, when viewed from either side of the arrangement direction D1, the first needle assembly 31a and the second needle assembly 31b completely overlap), and the third needle assembly 31c is offset from the first needle assembly 31a, in particular, completely offset.

[0063] Further, in order to reduce the adverse effects of the above asymmetric structure layout on port matching performance and insertion loss when transmitting high frequency signals using the interconnector 3, a shield 32 is provided. In the present embodiment, as shown in Figure 2B and Figure 2C The shield 32 is in contact with the third needle assembly 31c at all times. The shield 32 includes two barrel portions 311 of the above elastic measurement needle assemblies 31, which are arranged side by side in parallel to each other, and the extending directions of the two barrel portions 311 are the same as those of the first needle assembly 31a, the second needle assembly 31b and the third needle assembly 31c. In the present embodiment, as shown in Figure 2D the centers of the cross sections of the two barrel portions 311 are on the same straight line as the center of the cross section of the third needle assembly 31c. The center of the cross section of the barrel portion 311 of the shield 32 closest to the first needle assembly 31a is on the same straight line as the centers of the cross sections of the first needle assembly 31a and the second needle assembly 31b. In this way, in the alignment direction D2, the barrel portion 311 of the shield 32 closest to the first needle assembly 31a is aligned with the first needle assembly 31a and the second needle assembly 31b, while the other barrel portion 311 is partially misaligned with the first needle assembly 31a and the second needle assembly 31b.

[0064] In the present embodiment, as shown in Figure 2D the minimum distance between the first needle assembly 31a and the second needle assembly 31b is L1, the minimum distance between the first needle assembly 31a and the third needle assembly 31c is L2, and the minimum distance between the shield 32 and the first needle assembly 31a is L3, then L1 < L3 < L2 is satisfied. In this way, through the above structural design, the asymmetric layout of the second needle assembly 31b and the third needle assembly 31c on both sides of the first needle assembly 31a is compensated by the shield 32, thereby greatly reducing the adverse effects of the above asymmetric structure layout on port matching performance and insertion loss when transmitting high frequency signals using the interconnector 3.

[0065] In the present embodiment, as shown in Figure 2AAs shown, the support structure includes a cover 33 and a base 34, the base 34 is formed with a hollow portion 34c, and the cover 33 is installed on the base 34 in a manner of covering the opening of the hollow portion 34c. The cover 33 is formed with a first connecting end 33e for installing the first connector 1, and the base 34 is formed with a second connecting end 34e for installing the second connector 2. The support structure is formed with a plurality of through holes extending from the first connecting end 33e to the second connecting end 34e, the through holes extend through the cover 33 and the base 34, and pass through the hollow portion 34c. The barrel portion 311 of the elastic measurement needle assembly 31 is installed in the through hole, for example, by means of transition fit or the like. When the elastic measurement needle assembly 31 is installed in the through hole, the other end of the first plunger 312 is located at the first connecting end 33e, and the other end of the second plunger 313 is located at the second connecting end 34e. The support structure is formed with a mounting hole 3h in communication with the through hole for installing the third needle assembly 31c, and the mounting hole 3h is used to accommodate the installation of the shield 32. The mounting hole 3h should ensure that the shield 32 can be in contact with the third needle assembly 31c. The plurality of elastic measurement needle assemblies 31 and the shield 32 pass through the hollow portion 34c, facilitating the installation and removal of the elastic measurement needle assemblies 31 and the shield 32.

[0066] When it is necessary to realize the signal communication between the first connector 1 and the second connector 2 by means of the above-mentioned inter-connector connection mechanism 3, the plurality of elastic measurement needle assemblies 31 (including the first needle assembly 31a, the second needle assembly 31b and the third needle assembly 31c) can be inserted into the corresponding through holes of the support structure, and the shield 32 can be installed into the mounting hole 3h adjacent to the through hole of the third needle assembly 31c. Then, the first connector 1 is installed into the first connecting end 33e of the cover 33, and then, as shown by the hollow arrow, the second connector 2 is installed into, for example, abuts against, the second connecting end 34e of the base 34. In this way, the inter-connector connection mechanism 3 of the first embodiment of the present application can realize the signal communication between the pins of the first connector 1 and the second connector 2 in a convenient and fast manner, and will not cause damage to the first connector 1 and the second connector 2; moreover, since the inter-connector connection mechanism 3 of the first embodiment of the present application is provided with the shield 32, even in the case of the asymmetric structural layout of the ground pins on both sides of the high-frequency signal pins, the adverse effects of such asymmetric structural layout on the port matching performance and the insertion loss when transmitting high-frequency signals by means of the inter-connector connection mechanism 3 can be reduced. Figure 2A

[0067] The following describes the inter-connector connection mechanism according to the second embodiment of the present application.

[0068] (The inter-connector connection mechanism according to the second embodiment of the present application)

[0069] ​The joint connection mechanism according to the second embodiment of this application and the joint connection mechanism 3 according to the first embodiment of this application achieve the same function in principle and have basically the same structure. The following mainly describes the differences between the two.

[0070] like Figure 3 As shown, in this embodiment, the center of the cross-section of the cylindrical portion 311 closest to the first needle assembly 31a in the shield 32 is not on the same straight line as the center of the cross-section of the first needle assembly 31a and the center of the cross-section of the second needle assembly 31b. Furthermore, in the alignment direction D2, the cylindrical portion 311 closest to the first needle assembly 31a in the shield 32 is partially offset from the first needle assembly 31a.

[0071] In addition, in this embodiment, let the minimum distance between the first needle assembly 31a and the second needle assembly 31b be L1, the minimum distance between the first needle assembly 31a and the third needle assembly 31c be L2, and the minimum distance between the shield 32 and the first needle assembly 31a be L3, then L1=L3. <L2。

[0072] Thus, through the above structural design, the same technical effect as the first embodiment can be achieved.

[0073] The following describes a connector connection mechanism according to a third embodiment of this application.

[0074] (The connector connection mechanism according to the third embodiment of this application)

[0075] The joint connection mechanism of the third embodiment of this application and the joint connection mechanism 3 of the first embodiment of this application achieve the same function in principle and have basically the same structure. The following mainly describes the differences between the two.

[0076] like Figure 4 As shown, in this embodiment, the centers of the cross-sections of the two cylindrical portions 311 in the shield 32 and the center of the cross-section of the third needle assembly 31c are not on the same straight line. The center of the cross-section of the cylindrical portion 311 in the shield 32 closest to the first needle assembly 31a is not on the same straight line as the center of the cross-section of the first needle assembly 31a and the center of the cross-section of the second needle assembly 31b. In the alignment direction D2, the cylindrical portion 311 in the shield 32 closest to the first needle assembly 31a is partially offset from the first needle assembly 31a.

[0077] In addition, in this embodiment, let the minimum distance between the first pin assembly 31a and the second pin assembly 31b be L1, the minimum distance between the first pin assembly 31a and the third pin assembly 31c be L2, and the minimum distance between the shield 32 and the first pin assembly 31a be L3. Then, L1 < L3 < L2 is satisfied. In this way, through the above structural design, the same technical effects as those in the first embodiment can be achieved.

[0078] The following compares and describes the performance when the first connector 1 and the second connector 2 achieve signal connection by using the connector connection mechanism of the first embodiment and the second embodiment of the present application with the performance when using the existing connector connection mechanism to achieve signal connection in combination with the accompanying drawings of the specification.

[0079] Figure 5A shows the port matching performance of the first pin assembly 31a when the first connector 1 and the second connector 2 achieve signal connection by using the connector connection mechanism of the first embodiment and the second embodiment of the present application and the port matching performance of the first pin assembly 31a when using the existing connector connection mechanism to achieve signal connection. In Figure 5A the abscissa corresponds to the frequency of the transmitted high-frequency signal, with the unit of GHz; the ordinate is the value of S11 in the S parameter, with the unit of dB. In addition, in Figure 5A A corresponds to the existing connector connection mechanism, which does not have the shield 32 of the present application, B corresponds to the connector connection mechanism of the first embodiment of the present application, and C corresponds to the connector connection mechanism of the second embodiment of the present application. S11 reflects the port matching performance, and the smaller the value, the better the port matching performance. It can be seen from Figure 5A that when using the connector connection mechanism of the present application, the port matching performance is better than that of the existing connector connection mechanism.

[0080] Figure 5B shows the insertion loss performance of the first pin assembly 31a when the first connector 1 and the second connector 2 achieve signal connection by using the connector connection mechanism of the first embodiment and the second embodiment of the present application and the insertion loss performance of the first pin assembly 31a when using the existing connector connection mechanism to achieve signal connection. In Figure 5B the abscissa corresponds to the frequency of the transmitted high-frequency signal, with the unit of GHz, and the ordinate is the value of S21 in the S parameter, with the unit of dB. In addition, in Figure 5B A corresponds to the existing connector connection mechanism, which does not have the shield 32 of the present application, B corresponds to the connector connection mechanism of the first embodiment of the present application, and C corresponds to the connector connection mechanism of the second embodiment of the present application.
