Description

Technical Field

[0001] This invention belongs to the field of blind mating interconnect technology, and in particular relates to a comprehensive performance test platform for multi-connector blind mating interconnect. Background Technology

[0002] Traditional electrical and liquid-cooled interconnect technologies typically employ manual connector assembly, requiring manual disassembly and assembly, a tedious and time-consuming process. Blind-mating interconnect technology, currently the mainstream interconnect method, offers advantages such as simple installation and disassembly, fast insertion and insertion speeds, smooth and stable separation, and excellent high-frequency characteristics. It is widely used in the rapid connection of small electronic equipment, such as blind-mating RF coaxial connectors between T / R units and high-frequency cabinets. This technology adopts a modular design approach, using a unified interface structure and guide device design to achieve rapid connection and replacement between different components, thereby improving equipment interchangeability and reliability and shortening the time required for equipment assembly and disassembly.

[0003] While blind mating technologies for single electrical connectors or liquid-cooled connectors are relatively mature, they still suffer from issues such as insufficient radial guiding capability, inadequate radial and axial tolerance, and poor connection reliability. Complex, large-scale integrated blind mating structures with multiple connectors (optical, electrical, hydraulic, etc.) further complicate these problems, easily leading to issues like guide jamming, incomplete insertion, poor contact, unstable performance, coolant leakage, and even equipment burnout.

[0004] The ultimate goal of blind mating interconnects is to ensure reliable transmission of various internal signal media while achieving rapid mating. The reliability of these signal media transmissions directly reflects the overall performance of the blind mating interconnect. Therefore, comprehensive performance testing of multiple connectors in blind mating interconnects is essential. Unlike traditional small-size single blind mating connections, multi-connector blind mating connections have characteristics such as a wide variety of transmitted signal media, high fluctuation requirements (for example, the maximum fluctuation of a certain optoelectronic connector is ±0.3mm), and large system load. Common methods are difficult to meet their comprehensive performance testing requirements. Summary of the Invention

[0041] 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 use non-precise ratios, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0042] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0043] The main performance indicators of blind mating interconnects include: float, insertion and extraction force, insertion and insertion distance range, optical and electrical performance such as conductivity and loss, and fluid performance such as flow rate and pressure loss.

[0044] The present invention will now be described in detail.

[0045] This embodiment takes the multi-connector blind mating interconnection condition consisting of a rectangular metal frame blind mating connector and a large floating blind mating fluid connector as an example to conduct corresponding analysis and explanation.

[0046] See Figure 1 This diagram illustrates the mating and insertion states of the multi-connector blind-mating interconnect comprehensive performance test platform. Figure 2 This diagram shows the multi-connector blind mating interconnect comprehensive performance test platform in its adjusted state. Figure 3A cross-sectional view of a multi-connector blind-mating interconnect comprehensive performance test platform in an adjusted state is shown. The multi-connector blind-mating interconnect comprehensive performance test platform includes a base 1, a first connector platform 2, a three-dimensional adjustment mechanism 3, an axial adjustment mechanism 4, a guide mechanism 5, a counterweight device 6, a blind-mating socket section 7, a blind-mating plug section 8, a first connecting tube 9, a second connecting tube 10, and a second connector platform 11.

[0047] Specifically, base 1 serves as the supporting structure for the entire test platform; the first connector platform 2 is connected to base 1 via a three-dimensional adjustment mechanism 3, the fixed part of the three-dimensional adjustment mechanism 3 is fixedly connected to base 1, and the movable part of the three-dimensional adjustment mechanism 3 is connected to the first connector platform 2; the second connector platform 11 is connected to base 1 via an axial adjustment mechanism 4, the fixed part of the axial adjustment mechanism 4 is connected to base 1, and the movable part of the axial adjustment mechanism 4 is fixedly connected to the second connector platform 11; the displacement of the first connector platform 2 is adjusted by adjusting the movable part of the three-dimensional adjustment mechanism 3, and the axial displacement of the second connector platform 11 is adjusted by adjusting the movable part of the axial adjustment mechanism 4; the plug and socket of the connector under test are fixedly mounted on the first connector platform 2 and the second connector platform 11, respectively.

[0048] In this embodiment, the position of the socket set on the first connector platform 2 is adjusted by the three-dimensional adjustment mechanism 3, which can realize the relative adjustment of the position of the socket and the plug to achieve blind insertion test with different offset angles and different insertion depths.

The fixed pulley 602 is disposed on the base 1, and the counterweight cylinder 603 pulls the first connector platform 2 through the wire rope 601 with the fixed pulley 602 as the fulcrum.

[0050] The multi-connector blind-mating interconnect comprehensive performance test platform of this embodiment uses a counterweight device 6 to unload the gravity of the blind-mating socket 7, so that the three-dimensional adjustment mechanism 3 only needs to overcome a small amount of resistance when making minor adjustments. This invention is particularly suitable for testing heavy integrated and modular blind-mating interconnects. It uses a fixed pulley block 602, a steel wire rope 601, a counterweight cylinder 603, etc., to unload the gravity, so that the three-dimensional adjustment mechanism 3 can overcome the gravity of the blind-mating interconnect components when adjusting.

[0051] Preferably, the test platform further includes a guide mechanism 5 fixedly connected to the base 1, and the second connector platform 11 is slidably connected to the guide mechanism 5.

[0052] Further, see Figure 11 The guiding mechanism 5 further includes a guide shaft 501 and a linear bearing 502. The guide shaft 501 is fixedly connected to the base 1, and the linear bearing 502 is fixedly connected to the second connector platform 11. The guide shaft 501 passes through the linear bearing 502. The linear bearing 502 and the linear guide shaft 501 are used in combination, utilizing the rolling of steel balls within the linear bearing 502 to achieve linear motion, thus realizing low-friction, high-precision linear motion.

[0053] Preferred, see Figure 3 and Figure 10 The axial adjustment mechanism 4 further includes a drive screw 401, a nut slider 402, a fixed nut block 403, a fixed frame 404, a sliding frame 405, and a hand crank 406. The fixed nut block 403 is fixedly mounted on the fixed frame 404, and the nut slider 402 is fixedly mounted on the sliding frame 405. The drive screw 401 is provided with two threads with different leads corresponding to the fixed nut block 403 and the nut slider 402, respectively. The drive screw 401 passes through the fixed nut block 403 and the nut slider 402, and the hand crank 406 is located at the control end of the drive screw 401.

[0054] The relative movement of plug 8 to socket 7 is achieved by using differential screw drive, which does not require a very small lead or pitch. It can provide a larger insertion and extraction force while providing a small feed amount, and the insertion and extraction process is very smooth.

[0055] In one embodiment, the axial adjustment mechanism 4 further includes a drive screw 401, a fixed nut block 403, a fixed frame 404, a sliding frame 405, and a hand crank 406.

[0057] Preferred, see Figure 9The three-dimensional adjustment mechanism 3 further includes an X-axis adjustment mechanism 302, a Y-axis adjustment mechanism 303, a Z-axis adjustment mechanism 304, and a connecting bracket 301. The connecting bracket 301 is fixedly connected to the first connector platform 2. The X-axis adjustment mechanism 302 is slidably connected to the connecting bracket 301, the Y-axis adjustment mechanism 303 is slidably connected to the X-axis adjustment mechanism 302, and the Z-axis adjustment mechanism 304 is slidably connected to the Y-axis adjustment mechanism 303.

[0058] The XYZ three-dimensional adjustment mechanism 3 enables the blind socket to obtain an initial floating amount in any direction in three dimensions relative to the blind plug, making the adjustment more comprehensive and able to meet the needs of the test.

[0059] Preferably, the X-axis adjustment mechanism 302, the Y-axis adjustment mechanism 303 and the Z-axis adjustment mechanism 304 are each provided with a corresponding scale.

[0060] By setting a corresponding scale, the blind-plug socket can obtain an initial floating amount in any direction in three dimensions relative to the blind-plug plug, and the adjustment process can be quantified.

[0061] Preferably, a first connecting pipe 9 is provided at the lower end of the plug or socket mounting position of the first connector platform 2, and a second connecting pipe 10 is provided at the upper end of the plug or socket mounting position of the second connector platform 11. The first connecting pipe 9 and the second connecting pipe 10 are used to guide cables or serve as liquid pipelines.

[0062] Preferably, the socket 7 is provided with a socket connection plate 701, a fluid connection socket 702, and a photoelectric connection socket 703, and the plug 8 is provided with a corresponding plug connection plate 801, a fluid connection plug 802, and a photoelectric connection plug 803.

[0063] See Figure 4 and Figure 5 The diagrams show the socket 7 and plug 8 respectively. The socket 7 and plug 8 are equipped with sockets or plugs of multiple different types of connectors, enabling blind mating tests for multiple connectors, improving testing efficiency and increasing compatibility.

[0064] Preferred, see Figure 6The diagram illustrates another embodiment of the photoelectric socket 703 and photoelectric plug 803. The photoelectric socket 703 mainly includes a photoelectric socket housing 703A, a photoelectric socket mounting and positioning element 703B, a photoelectric socket positioning pin hole 703C, a photoelectric socket contact mounting cavity 703D, a photoelectric socket contact 703E, and a photoelectric socket tail cover 703F. The photoelectric plug 803 mainly includes a photoelectric plug housing 803A, a photoelectric plug floating mounting sleeve 803B, a photoelectric plug positioning pin hole 803C, a photoelectric plug contact mounting cavity 803D, a photoelectric plug contact 803E, and a photoelectric plug tail cover 803F. See also... Figure 7 A schematic diagram of a blind-mating fluid connector is shown, including a fluid socket 702 and a fluid plug 802. See also Figure 8 This refers to the state where the blind-plug socket and blind-plug plug are separated and plugged in.

[0065] In one embodiment, see Figure 12 It is a single fluid connector, including a fluid connector 1201 disposed on a blind-mating socket 12 and a fluid connector 1301 disposed on a blind-mating plug 13.

[0066] In one embodiment, see Figure 13 It is a single optoelectronic connector, including an optoelectronic connector 1401 disposed on a blind mating socket 14 and an optoelectronic connector 1501 disposed on a blind mating socket 15.

[0067] In one embodiment, see Figure 14 and Figure 15 The multi-connector blind-mating interconnect is integrated into the conductive slip ring 16, which makes the blind-mating connectors very heavy. The three-dimensional adjustment mechanism 3 typically has a load capacity of only 5-10 kg, making it difficult to overcome the weight of the integrated module. Using electric or other precision adjustment mechanisms is usually very costly. Therefore, using a gravity unloading device 6 allows for very convenient micro-adjustment of the conductive slip ring.

[0068] In one embodiment, see Figure 16 and Figure 17 The actual floating amount and insertion distance of the blind insertion after insertion are not equal to the adjustment value of the three-axis fine adjustment slide. The influence of transmission chain clearance and insertion / extraction force deformation should also be added. The actual radial floating amount after insertion is read using vernier caliper 17, and the actual axial floating amount after insertion is read using feeler gauge 18.

[0069] See attached document Figure 1 Appendix Figure 2 Appendix Figure 18During adjustment, the blind-plug socket 7 is finely adjusted in three directions using the three-dimensional adjustment mechanism 3. After adjustment, the gap between the blind-plug socket 7 and the base 1 is compensated by the compensation shim 19. The umbo hole on the blind-plug socket 7 can accommodate the radial connection between the blind-plug socket 7 and the base 1. After connecting the blind-plug socket 7 and the base 1 with screws, the micrometer knob of the three-dimensional adjustment mechanism 3 is appropriately retracted to put the entire floating amount adjustment mechanism in an unloaded state. At this time, the axial adjustment mechanism 4 performs the insertion and connection operation. After insertion and connection, the first insertion platform 2 and the second insertion platform 11 are connected by screws to achieve locking. Finally, the true floating amount data is obtained by precise measurement using a vernier caliper 17, a micrometer screw gauge, a feeler gauge 18, etc. This process is repeated to obtain the insertion and connection states under different floating amounts.

[0070] In one embodiment, one end of the first connecting pipe 9 and the second connecting pipe 10 are connected to a liquid cooling source, a signal source, or a light source, while the other end is connected to testing equipment such as a pressure gauge, flow meter, power meter, or optical power meter to measure the corresponding loss data. This allows for the acquisition of photoelectric fluid performance data under different float values.

[0071] In one embodiment, performance data such as insertion and extraction force can be obtained by converting the insertion and extraction actuator using a torque wrench.

[0072] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
