Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and in particular to an integrated connector testing system. Background Technology

[0002] Most existing integrated microstrip connectors are rigid structures, which are split structures in which the connector body (usually containing an inner conductor and an insulating medium) is assembled into a fixed housing. The signal contacts on the microstrip substrate (or similar circuit board) are directly plugged into the rigid signal pins (inner conductor) inside the connector.

[0003] Even a tiny installation deviation between the microstrip substrate and the connector can cause the pads on the substrate and the rigid signal pins of the connector to malfunction, resulting in poor contact, sudden changes in signal impedance, and increased signal reflection. This severely affects the transmission quality of high-frequency signals (such as radio frequency signals) and can even lead to communication interruptions. This makes the production and assembly process very difficult and results in a low yield.

[0004] In addition, during equipment operation or transportation, unavoidable vibrations will be transmitted to the rigid connection interface. Without buffering, the vibration energy will directly act on the contact point between the signal pin and the substrate pad, causing fretting wear. That is, the tiny relative movement between the contact points will wear away the gold plating layer on the contact surface, leading to oxidation, increased contact resistance, and eventually complete failure. At the same time, continuous stress may also cause fatigue fracture of the signal pin or substrate pad, which greatly reduces the service life of the connector in vibration environments such as automotive, aerospace, and industrial machinery.

[0005] When a split-type connector (with the connector inserted into the housing) fails, the entire connector module often needs to be removed from the device, or even the entire component needs to be replaced. This makes the repair and replacement process cumbersome, time-consuming, and can result in high spare parts costs due to the need to replace the entire component. For multi-channel integrated connectors, if one channel fails, the entire connector needs to be replaced, leading to extremely high maintenance costs, which needs improvement. Summary of the Invention

[0031] This invention decomposes the housing into a combination design of connecting blocks, intermediate connecting blocks, and mounting blocks, which allows the length and number of channels of the entire system to be flexibly configured according to testing requirements. By increasing or decreasing the number of mounting blocks, testing systems with different numbers of channels can be easily realized, improving the product's versatility and customization flexibility. Blocks with different functions such as end fixing, intermediate support, and signal installation can be manufactured, assembled, and maintained separately. If a block is damaged, only that module needs to be replaced, without replacing the entire bulky housing, reducing maintenance costs and difficulty.

[0032] This invention, by setting multiple block connecting components and fastening screws, can tighten all the independent detachable installation units and connecting units, and combine them into a complete shell with sufficient overall rigidity and mechanical strength, ensuring that the structure does not deform or loosen under insertion, removal and vibration conditions.

[0033] This invention employs a design where the upper threaded section connects to the connector and the lower threaded section connects to the lower block. A single screw can simultaneously fasten both parts, making the assembly process extremely simple and efficient. Furthermore, the fit between the upper threaded section and the connector facilitates removal of the connector during disassembly. A spring and anti-loosening block structure are incorporated within the connector, engaging with the upper threaded section of the screw. The spring continuously applies pressure to the anti-loosening block, thereby generating a continuous axial clamping force on the screw threads, forming an effective mechanical anti-loosening mechanism. This significantly resists screw loosening caused by long-term vibration in vibrating environments. Attached Figure Description

[0050] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1-16 The present invention will now be described in further detail.

[0051] Reference Figure 1-4 This application provides an integrated connector testing system, including a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 are detachably fixedly connected. The first housing 1 and the second housing 2 should be provided with matching screw holes, buckles or other connection structures so that the two can be tightly and detachably fixed together. The first housing 1 and the second housing 2 are not only the main body for mounting all internal components, but also serve as the overall outer conductor of the connector system, providing a unified reference ground and electromagnetic shielding for the internally transmitted radio frequency signals, thereby improving the overall system integrity and signal integrity.

[0052] The connector assembly 3 includes a connecting portion 31 located outside the first housing 1 and the second housing 2, and a replaceable signal module 32 inside. The connecting portion 31 and the replaceable signal module 32 are connected by an RF cable 33. The connecting portion 31 is used to connect to the subject under test, and the replaceable signal module 32 is used to connect to the microstrip substrate. The connector assembly 3 has several sets of connectors. The interface of the connecting portion 31 needs to be designed and manufactured according to the interface standard of the subject under test to ensure a compatible connection. The RF cable 33 is used to transmit RF signals between the connecting portion 31 and the replaceable signal module 32. One end of the cable is connected to the connecting portion 31, and the other end passes through the first housing 1 and connects to the replaceable signal module 32.

[0053] In use, the replaceable signal modules 32 of multiple connector assemblies are installed in the mounting body formed by the combination of the first housing 1 and the second housing 2 according to the designed layout. The RF cable 33 is led out from the inside and connected to the external connection part 31. Finally, the first housing 1 and the second housing 2 are closed and fixed to form a complete connector testing system integrating multiple independent test channels. One end of the system is used to connect to the microstrip substrate under test, and the other end is connected to the substrate under test through the RF cables 33 of each channel.

[0054] The connector assembly 3 is divided into an external connection part 31 and an internal replaceable signal module 32. This design achieves functional separation. When the internal module is damaged or the test interface needs to be replaced, there is no need to replace the entire connector or external cable, which significantly reduces maintenance costs and downtime. At the same time, the architecture with several groups facilitates multi-channel parallel testing and improves testing efficiency. The replaceable signal module 32 is designed specifically for connecting microstrip substrates, which meets the common needs of modern high-frequency circuit testing and enables the system to flexibly adapt to different interfaces of the device under test.

[0055] The first housing 1 has a plurality of first mounting cavities 11 on its inner side, and the second housing 2 has a plurality of second mounting cavities 21 that correspond to and are adapted to the first mounting cavities 11 on its inner side. The replaceable signal module 32 is installed inside the corresponding first mounting cavity 11 and second mounting cavity 21.

[0056] The end of the radio frequency cable 33 is processed to strip out a section of shielding layer 331 and core wire 332.

[0057] The first mounting cavity 11 is provided with a bushing 321, which is welded to the outside of the shielding layer 331 at the end of the radio frequency cable 33. A sealing ring 34 is provided on the top of the bushing 321 and located on the outside of the end of the radio frequency cable 33.

[0058] The bushing 321 has a first solder hole 326.

[0059] In use, the bushing 321 is fitted over the outer side of the shielding layer 331 at the cable end, ensuring good contact between the bushing and the shielding layer. Molten solder is injected through the first soldering hole 326, welding the bushing and the cable shielding layer into a single unit, achieving reliable grounding and stress relief. The resulting solder layer 328, as shown... Figure 3 As shown.

[0060] The bushing 321 is welded to the outside of the cable shielding layer 331 and cooperates with the housing mounting cavity to form a continuous and complete shielding path, effectively preventing radio frequency signal leakage and external electromagnetic interference. At the same time, the addition of a sealing ring improves the environmental sealing performance of the system, such as dustproof and moisture-proof performance, making it suitable for more severe working environments. The solder holes on the bushing 321 and the inner conductor facilitate the welding process to firmly fix the cable shielding layer 331 and the core wire 332 to the bushing 321 and the inner conductor, respectively.

[0061] The replaceable signal module 32 includes an insulating medium 323 detachably disposed inside the second mounting cavity 21. An inner conductor 322 and an inner conductor 325 are disposed vertically inside the insulating medium 323. The inner conductor 322 is soldered to the outer side of the core wire 332 at the end of the radio frequency cable 33. An elastic conductive interconnection element 324 is provided between the inner conductor 322 and the inner conductor 325 to realize the electrical connection and mechanical buffering of the inner conductor 322 and the inner conductor 325.

[0062] A second solder hole 327 is provided on the inner conductor 322.

[0063] During installation, the welded cable bushing 321 is placed into the first mounting cavity 11. At this time, the cable core 332 passes through the first mounting cavity and extends into the cavity formed by subsequent assembly. A sealing ring 34, such as an O-ring, is fitted onto the top of the bushing 321 and the outer side of the RF cable 33. When the first and second housings are closed, the wall of the second mounting cavity 21 presses against the sealing ring 34, achieving a seal at the mounting position.

[0064] The elastic conductive interconnect element 324 is elastic, which can effectively compensate for the mounting plane error, coplanarity deviation and slight misalignment between the microstrip substrate and the connector, ensuring good electrical contact even when assembly tolerances exist. When operating in a vibrating environment, the elastic conductive interconnect element 324 can absorb and buffer vibration energy, preventing vibration from being directly transmitted to the solder joint or microstrip pad, significantly reducing the risk of fretting wear, thereby greatly improving the reliability and service life of the connector in dynamic environments. The insulating medium 323 and the internal conductor group are set as an integral module in the second mounting cavity 21 and connected to the first housing 1 part through an elastic element, so that the entire replaceable signal module 32 can be disassembled and replaced separately, making maintenance extremely convenient.

[0065] The flexible conductive interconnect element 324 can be a metal felt button, a braided metal mesh, or a spring probe. A metal felt button is a columnar flexible conductor made of fine metal wires, such as beryllium copper or gold wire, woven or pressed together. It can be cut or pressed into appropriately sized holes for use. A braided metal mesh is a flexible metal mesh conductor that can be stamped into specific shapes. A spring probe consists of a precision spring, a probe, and a sleeve, providing precise travel and contact force. It is a common choice for high-frequency applications; when selecting one, it is necessary to ensure that its operating frequency range and rated current meet system requirements.

[0066] By implementing the flexible conductive interconnect element 324 in several ways, the flexible conductive interconnect element 324 is not limited to a single structure, and has a wider range of applicability and feasibility.

[0067] During assembly, inner conductor 2 325 is installed in the lower conductor mounting hole of insulating medium 323, and then the elastic conductive interconnect element 324 is inserted. Next, inner conductor 1 322 is placed in the upper conductor mounting hole of insulating medium 323, with its lower end contacting the upper end of elastic conductive interconnect element 324. At this point, the lower end of inner conductor 1 322 is in contact with the upper end of elastic conductive interconnect element 324, while the upper end of inner conductor 2 325 is in contact with the lower end of elastic conductive interconnect element 324. This forms a passage between inner conductor 1 322, elastic conductive interconnect element 324, and inner conductor 2 325. The elastic conductive interconnect element 324 is compressed within inner conductors 1 and 2, providing contact force and cushioning.

[0068] The assembled insulating medium 323, inner conductor one 322, inner conductor two 325, and elastic conductive interconnect element 324 are then placed as a single module into the second mounting cavity 21 of the second housing 2. The RF cable core 332, extending from one side of the first housing, is inserted into the hole of the inner conductor one 322, and solder is injected through the second soldering hole 327 to weld the core 332 to the inner conductor one 322. The resulting solder layer 328, as shown... Figure 3 As shown.

[0069] The replaceable signal module 32 is placed entirely into the second mounting cavity 21. The lower end of its inner conductor 325, typically spherical or convex, protrudes slightly from the inside of the housing for contact with the microstrip substrate. When the module needs to be replaced, simply loosen the first housing 1 to remove the replaceable signal module 32 entirely from the second mounting cavity 21.

[0070] In another preferred embodiment, instead of fabricating the first housing 1 and the second housing 2 into a single unit, they are each decomposed into several independent blocks. This design, which decomposes the housing into a combination of connecting blocks, intermediate connecting blocks, and mounting blocks, allows for flexible configuration of the overall system length and number of channels according to testing requirements. By increasing or decreasing the number of mounting blocks, testing systems with different numbers of channels can be easily implemented, improving the product's versatility and customization flexibility. Blocks with different functions, such as end fixing, intermediate support, and signal mounting, can be manufactured, assembled, and maintained separately. If a block is damaged, only that module needs to be replaced, without replacing the entire bulky housing, reducing maintenance costs and difficulty.

[0071] Please refer to the details. Figure 5-16The first housing 1 includes two first connecting blocks 12 located at the ends and a first intermediate connecting block 14 located between the two first connecting blocks 12, with two rows of first mounting blocks 13 provided between the first connecting blocks 12 and the first intermediate connecting block 14; the second housing 2 includes two second connecting blocks 22 located at the ends and a second intermediate connecting block 24 located between the two second connecting blocks 22, with two rows of second mounting blocks 23 provided between the second connecting blocks 22 and the second intermediate connecting block 24;

[0072] The first connecting block 12 and the second connecting block 22, as well as the first intermediate connecting block 14 and the second intermediate connecting block 24, can be detachably and fixedly connected. The number of the first mounting block 13 and the second mounting block 23 are the same and they correspond one-to-one.

[0073] In use, select the appropriate number of first mounting blocks 13 and second mounting blocks 23 according to the required total number of channels. Arrange them with the connecting blocks at both ends and the connecting block in the middle in the following order: end block, multiple mounting blocks, middle block, multiple mounting blocks, end block, where the middle block is optional. Fix all blocks in the longitudinal and vertical directions using the connecting mechanism described later, finally assembling them into a complete upper and lower shell. By increasing or decreasing the number of mounting blocks, the number of test channels can be flexibly increased or decreased.

[0074] During assembly, the pair of vertically aligned first connecting blocks 12 and second connecting blocks 22 are regarded as an end connecting unit; the pair of vertically aligned first intermediate connecting blocks 14 and second intermediate connecting blocks 24 are regarded as an intermediate connecting unit; and the pair of vertically aligned first mounting blocks 13 and second mounting blocks 23 are regarded as a detachable mounting unit, i.e., a channel unit, with the first mounting cavity 11 and the second mounting cavity 21 respectively opened inside the first mounting block 13 and the second mounting block 23.

[0075] A connecting mechanism is provided between adjacent removable installation units and on the mating surface between the removable installation unit and the end connecting unit or intermediate connecting unit for fastening the end removable installation unit, intermediate connecting unit and removable installation unit together. The connecting mechanism includes a connecting component 4 and a fastening screw 5 passing through the connecting component 4.

[0076] During assembly, all end units, intermediate units, and mounting units are first arranged and spliced ​​together in the left-right direction. Then, connecting components 4 are installed at the mating positions between each unit. Finally, fastening screws 5 are screwed in from top to bottom, passing through connecting components 4 and locking them to the lower unit, such as the block of the second housing 2. Through multiple such connection points, all the independent units are tightened in the longitudinal and vertical directions to form a rigid integral structure.

[0077] By setting multiple block connecting components 4 and fastening screws 5, all independent detachable installation units and connecting units can be tightened and combined into a complete shell with sufficient overall rigidity and mechanical strength, ensuring that the structure does not deform or loosen under insertion, removal and vibration conditions.

[0078] Please refer to Figure 5-9 Let the two sides of the first housing 1 be the outer edge side 61, and the side opposite to the outer edge side 61 be the inner edge side 62. The outer edge side 61 and the inner edge side 62 are respectively. The connecting component 4 is a first connector 41 set at the end corner of the inner edge side 62 of the easy-to-remove installation unit. Four first wedge strips 411 are evenly distributed on the outer periphery of the first connector 41. A first wedge groove 131 adapted to the first wedge strip 411 is opened on the end corner of the inner edge side 62 of the first mounting block 13. A second wedge groove 231 adapted to the first wedge strip 411 is opened on the inner side of the end corner of the inner edge side 62 of the second mounting block 23.

[0079] The first connecting block 12 and the first intermediate connecting block 14 are also provided with a first wedge groove 131 and a second wedge groove 231 respectively. The first connecting member 41 is inserted into the inner side of the first wedge groove 131 and the second wedge groove 231 through the first wedge strip 411.

[0080] The bottom of the second wedge groove 231 is provided with a first threaded hole 234, and the fastening screw 5 is threaded to the inside of the first threaded hole 234.

[0081] After assembling all the block units, insert the first connector 41 from above into the adjacent unit, for example, between the first wedge groove 131 and the second wedge groove 231 of a first mounting block and a first connecting block. The first wedge strip 411 will engage with the corresponding wedge groove for horizontal positioning. Then, screw the fastening screw 5 downward through the through hole in the center of the first connector 41, with the lower end of the screw threaded into the first threaded hole 234 at the bottom of the lower second wedge groove 231. Tighten the screw to fix the upper and lower block units together through this connector. Figure 9 This demonstrates the usage status of this method.

[0082] By interlocking the wedge strips and wedge grooves, precise pre-positioning and circumferential anti-rotation fixation of adjacent blocks in the plane can be achieved before tightening the screws. This greatly simplifies the assembly alignment process, improves assembly efficiency, and prevents misalignment between modules. The wedge fit has good shear resistance, and the final tightening of the screws provides reliable axial locking force.

[0083] The mounting sides 63 on both sides of the first mounting block 13 are provided with matching first slots 132 and first inserts 133. The first connecting block 12 and the first intermediate connecting block 14 are also provided with first slots 132 and first inserts 133. Adjacent first mounting blocks 13, first mounting blocks 13, first connecting blocks 12 and first intermediate connecting blocks 14 are all connected by the cooperation of first slots 132 and first inserts 133.

[0084] The mounting sides 63 on both sides of the second mounting block 23 are provided with matching second slots 232 and second inserts 233. The second connecting block 22 and the second intermediate connecting block 24 are also provided with second inserts 233 and second slots 232 respectively.

[0085] A first slot 132 and a first insert 133 are machined on the side of the first mounting block 13. The first slot 132 and the first insert 133 are also machined on the side of the first connecting block 12 and the first intermediate connecting block 14, so that when adjacent blocks are spliced ​​longitudinally, the first insert 133 of one block can be inserted into the first slot 132 of the adjacent block. Similarly, a second slot 232 is machined on the left side of the second mounting block 23, and a second insert 233 is machined on the right side. Corresponding slots and inserts are also machined on the side of the second connecting block 22 and the second intermediate connecting block 24.

[0086] During assembly, when arranging and splicing the various blocks longitudinally, in addition to the wedge-shaped connectors at the end corners for positioning, the sides are also aligned and limited by the cooperation of inserts and slots. This makes the position of all blocks in the longitudinal and transverse directions basically determined before the screws are finally tightened, making assembly more convenient, with higher lateral connection strength and a flatter shell side.

[0087] Based on the wedge-shaped positioning at the end corners, a slot and insert structure is added to the side of the block to further enhance the lateral connection strength and positioning accuracy of adjacent blocks. The side insertion structure allows all blocks to interlock with each other in the lateral direction, forming an almost seamless complete sidewall. This not only better prevents the intrusion of external foreign objects, but also improves the electromagnetic shielding effect and enhances the overall integrity of the shell.

[0088] In a preferred embodiment, please refer to Figure 10-16 The connecting component 4 is a second connector 42 disposed on the inner edge 62 and the two sides of the mounting side 63 of the detachable mounting unit. The second connector 42 is provided with a second wedge strip 421 on both sides. The inner edge 62 and the two sides of the mounting side 63 of the first mounting block 13 are provided with a third wedge groove 134 adapted to the second wedge strip 421. The inner edge 62 and the two sides of the mounting side 63 of the second mounting block 23 are provided with a fourth wedge groove 235 adapted to the second wedge strip 421.

[0089] The first connecting block 12 and the first intermediate connecting block 14 are also provided with a third wedge groove 134 and a fourth wedge groove 235. The second connecting piece 42 is inserted into the inner side of the third wedge groove 134 and the fourth wedge groove 235 through the second wedge strip 421.

[0090] The bottom of the fourth wedge groove 235 is provided with a second threaded hole 236, and the fastening screw 5 is threaded into the inner side of the second threaded hole 236;

[0091] During assembly, the second wedge-shaped strip 421 of the second connector 42 is inserted from top to bottom into the combined groove formed by the third wedge-shaped groove 134 and the fourth wedge-shaped groove 235 at the mating point of adjacent blocks. The wedge-shaped strip slides into place within the groove, achieving positioning. Then, a fastening screw 5 is screwed into the through hole at the center of the second connector 42, with the lower end of the screw connecting to the second threaded hole 236. Figure 14 As shown, in this method, the second wedge-shaped strip 421 of the second connector 42 provides constraint in the inner edge and two side directions of the block, resulting in stronger resistance to torsion and bending.

[0092] The above proposes another connector design, in which wedge strips are set on both sides of the connector, so that the connector can simultaneously generate a wedge tightening effect on the inner edge side 62 of the block and the mounting sides 63 on both sides, providing the block with better resistance to torsion and lateral bending, and making the structure more stable under complex stress.

[0093] The fastening screw 5 includes an upper threaded section 51 and a lower threaded section 52. The outer diameter of the upper threaded section 51 is larger than the outer diameter of the lower threaded section 52. The upper threaded section 51 is threadedly connected to the corresponding first connector 41 or second connector 42, and the lower threaded section 52 is threadedly connected to the corresponding first threaded hole 234 or second threaded hole 236.

[0094] A third mounting cavity 71 is provided on the inner side of the bottom of the first connector 41 or the second connector 42. An anti-loosening block 73 is slidably connected to the inner side of the third mounting cavity 71. A spring 72 is provided on the top of the anti-loosening block 73. The two ends of the spring 72 are respectively connected to the anti-loosening block 73 and the top of the inner side of the third mounting cavity 71. The upper threaded section 51 is threadedly connected to the anti-loosening block 73.

[0095] In use, a compression spring 72 is placed into the third mounting cavity 71, and then the anti-loosening block 73 is placed in, pressing it against the spring 72. At this time, the anti-loosening block 73 can slide up and down in the mounting cavity, but is pushed downward by the spring 72. During connection, the fastening screw 5 is screwed in from above the connector, and its upper threaded section 51 will engage with the thread of the anti-loosening block 73. As it is screwed in further, the lower threaded section 52 of the screw will pass through the connector and engage with the first threaded hole 234 or the second threaded hole 236 on the lower block, such as the second mounting block. During the process of the lower threaded section 52 engaging with the thread of the lower block, the upper threaded section 51 is also engaging with the anti-loosening block 73, during which the anti-loosening block 73 will move upward. When finally tightened, the screw head will press against the connector, and the upper thread section 51 of the screw will be fully engaged with the anti-loosening block 73. At this time, the elastic force of the spring 72 will continue to push the anti-loosening block 73 downward, so that there is always an additional axial clamping force between the anti-loosening block 73 and the screw thread, and between the screw and the lower threaded hole. This effectively prevents the screw from loosening due to slight rotation in a vibrating environment. When disassembling, the spring force needs to be overcome to unscrew the screw.

[0096] On the other hand, during disassembly, the lower threaded section 52 can be unscrewed from the lower block first, and the upper threaded section 51 is still threadedly connected to the upper block. At this time, the connecting component 4 can be pulled out by the fastening screw 5 without the need for additional tools, which is convenient for disassembly and assembly.

[0097] The design employs an upper threaded section 51 to connect the connector and a lower threaded section 52 to connect the lower block. A single screw can simultaneously fasten both the upper and lower parts, making the assembly process extremely simple and efficient. Furthermore, the fit between the upper threaded section 51 and the connector facilitates removal of the connector during disassembly. A spring 72 and an anti-loosening block 73 are installed inside the connector. These components work in conjunction with the upper threaded section 51 of the screw. The spring 72 continuously applies pressure to the anti-loosening block 73, thereby generating a continuous axial clamping force on the screw threads, forming an effective mechanical anti-loosening mechanism. This significantly resists screw loosening caused by long-term vibration in vibrating environments.

[0098] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
