Description

Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to a small-size connector assembly with an integrated filter. Background Art

[0002] In the field of small-size connectors with integrated filters, traditional technologies face the dual challenges of welding processes and shielding effectiveness. On the one hand, filters and connectors are commonly connected by welding. High temperatures not only cause filter performance deviations, but also cause stress concentration at the solder joints, causing signal loss and electromagnetic interference. In addition, the complex welding process is difficult to adapt to the mass production and maintenance requirements of small-size connectors. On the other hand, when the temperature rises, the performance of the high-permeability metal or conductive material of the fixed shielding structure will significantly degrade. The decrease in magnetic permeability or electrical conductivity leads to a weakening of shielding effectiveness, which cannot dynamically adapt to the electromagnetic compatibility requirements of high-frequency and high-power scenarios.

[0003] To this end, we propose a small-size connector assembly with integrated filter. Summary of the Invention

[0018] Compared with the existing technology, it has the following beneficial effects:

[0019] 1. The connector housing of the present invention adopts a segmented design of the upper housing and the lower housing, which is fixed with the connecting parts and bolts on the front and rear sides to facilitate disassembly and maintenance. In the assembly sealing components on the left and right sides, the rotation limit frame cooperates with the connecting bolts and connecting screw holes to accurately position and enhance the structural stability. Conductive seals and elastic seals are respectively arranged in the sealing grooves at the contact point of the upper housing and the lower housing.

[0020] 2. The limiting connecting frame and the filter positioning frame in the connecting assembly of the present invention are slidably matched through the limiting groove. The movable control frame in the movable groove is under the action of the reset spring and the positioning rod, and realizes the elastic engagement and positioning of the filter by connecting the inclined groove, connecting the slider and connecting the positioning block and the positioning hole, replacing the traditional welding method, avoiding welding loss and interference. At the same time, the elastic connection between the metal wool button and the positioning hole reduces the contact resistance, improves the low loss and anti-interference performance of signal transmission, and the design of the reset spring ensures the automatic reset and precise positioning of the movable control frame during assembly, ensuring the stability and reliability of the filter installation.

[0021] 3. In the dynamic shielding assembly within the upper and lower housings of the present invention, a rotating rod, pivotally mounted within mounting grooves on either side of the position-limiting connecting frame, wraps around the composite shielding layer. This rod, coupled with the adjusting block and adjusting slot, slides along the connector's inner wall. The adjusting rod within the fixed column is connected to the adjusting block at one end and equipped with an adjusting piston at the other. The rod slides within the fixed column's adjusting cavity. Thermally conductive fins on the fixed column's periphery transfer heat to an expandable rubber sleeve within the dynamic cavity. The heat-induced deformation of the expandable rubber sleeve compresses the gas within the dynamic cavity, pushing the adjusting piston through air ducts and driving the adjusting rod to slide. This causes the adjusting block to move within the adjusting slot, which in turn causes the composite shielding layer to deploy from the rotating rod, expanding the shielding area. This design leverages the temperature-responsive nature of the expandable rubber sleeve to automatically expand the composite shielding layer as temperature rises, dynamically enhancing its magnetic field shielding capability. This addresses the issue of traditional shielding layers experiencing reduced shielding effectiveness due to material degradation at high temperatures. The thermally conductive fins accelerate temperature transfer, enabling more timely shielding adjustment. The torsion spring ensures that the composite shielding layer automatically retracts when the temperature drops, creating a dynamic, adaptive shielding system that improves the connector's electromagnetic compatibility and stability under varying temperature environments.

[0022] Other features and advantages of the present invention will be set forth in the following description and, in part, will become apparent from the description or will be understood through implementation of the present invention.

[0038] A connecting component is provided in the middle of the upper shell 2 and the lower shell 3, and a filter 11 is provided between the two connecting components.

[0043] It should be noted that when assembling and connecting the filter 11 and the connector, first, the filter 11 and the filter positioning frames 12 arranged on the front and rear sides thereof are placed into the limiting connecting frame 5 inside the lower shell 3, and the two filter positioning frames 12 slide into the limiting grooves 14 on the front and rear sides of the limiting connecting frame 5 respectively. At this time, the lower part of the filter 11 as a whole is in the limiting connecting frame 5 inside the lower shell 3, and then the upper shell 2 and the lower shell 3 are assembled and connected. When the bottom of the upper shell 2 and the top of the lower shell 3 are matched and assembled, the movable control frame 16 located in the limiting connecting frame 5 inside the upper shell 2 contacts the movable control frame 16 in the limiting connecting frame 5 inside the lower shell 3, and the bottom end surface of the upper shell 2 and the lower shell 3 are in contact.

[0045] Example 2

[0046] See also Figure 1 、 Figure 5 、 Figure 8 and Figure 9 As shown, this embodiment is a further explanation of the above-mentioned embodiment scheme. Dynamic shielding components are provided inside the upper shell 2 and the lower shell 3. The dynamic shielding components include an adjustment frame 28 and a fixed column 25. The left and right sides of the limiting connecting frame 5 are provided with mounting grooves 22, and the insides of the mounting grooves 22 on both sides are rotatably provided with rotating rods 23, wherein three mounting grooves 22 are provided on the left side of the limiting connecting frame 5, and torsion springs are provided at both ends of the rotating rods 23 inside the three mounting grooves 22; a composite shielding layer 24 is wrapped around the surface of the rotating rod 23, and an adjustment frame 28 is fixedly provided on one side of the composite shielding layer 24, and adjustment blocks 26 are fixedly provided on both sides of the adjustment frame 28, and adjustment slides 27 cooperating with the adjustment blocks 26 are provided on both sides of the inner walls of the upper shell 2 and the lower shell 3; fixed columns 25 are fixedly provided on both sides of the limiting connecting frame 5, and the internal sliding The cam 35 is provided with an adjusting rod 29, one end of which is fixedly connected to one side of the adjusting block 26, and an adjusting piston 35 is fixedly provided on the other end of the adjusting rod 29. An adjusting chamber 31 is provided inside the fixed column 25, and the fixed column 25 is slidably connected inside the adjusting chamber 31. A dynamic chamber 32 is also provided inside the fixed column 25 and on the outside of the adjusting chamber 31, and an expansion rubber sleeve 30 is fixedly provided inside the dynamic chamber 32. A plurality of heat-conducting fins 33 are fixedly provided on the outer peripheral surface of the fixed column 25, and one side of the plurality of heat-conducting fins 33 extends into the interior of the dynamic chamber 32, wherein one side of the plurality of heat-conducting fins 33 located inside the dynamic chamber 32 contacts the surface of the expansion rubber sleeve 30, and the interior of the expansion rubber sleeve 30 is filled with inert gas; an air guide hole 34 is also provided on one side of the interior of the dynamic chamber 32, and the interior of the air guide hole 34 is connected to the interior of the adjusting chamber 31.

[0047] It should be noted that when installing the dynamic shielding component, the composite shielding layer 24 is installed on both sides of the limiting connecting frame 5 in conjunction with the fixing column 25 and the adjusting frame 28. The composite shielding layer 24 on both sides of the limiting connecting frame 5 is used to shield the filter 11 from the magnetic field. At the same time, when the temperature inside the connector rises, the heat is absorbed by the heat-conducting fins 33 provided on the surface of the fixing column 25 and then conducted into the dynamic cavity 32. The expansion rubber sleeve 30 inside the dynamic cavity 32 is deformed after being heated, thereby squeezing the space inside the dynamic cavity 32, and the gas inside the dynamic cavity 32 is discharged through the air guide hole. 34 is pushed into the interior of the adjusting chamber 31, thereby pushing the adjusting piston 35 to slide to one side inside the adjusting chamber 31. At this time, one end of the adjusting rod 29 slides to one side along the adjusting chamber 31, and one end of the adjusting rod 29 is used to drive the adjusting block 26 to slide inside the adjusting groove 27, so that the adjusting block 26 cooperates with the adjusting frame 28 to drive the composite shielding layer 24 to extend to one side, and unfold the composite shielding layer 24 wrapped around the surface of the rotating rod 23, further expanding the spreading area of ​​the composite shielding layer 24 inside the connector, thereby playing a dynamic shielding adjustment role on the filter 11 inside the connector.

[0048] In a specific embodiment, in the dynamic shielding assembly within the upper shell 2 and the lower shell 3 of the present invention, the rotating rod 23 rotatably arranged in the mounting grooves 22 on both sides of the limiting connecting frame 5 is provided with a torsion spring wrapped around the composite shielding layer 24 at both ends of the rotating rod 23 in the three mounting grooves 22 on the left side, which cooperates with the adjusting block 26 and the adjusting slide 27 through the adjusting frame 28 and can slide along the inner wall of the connector; the adjusting rod 29 in the fixed column 25 is connected to the adjusting block 26 at one end and provided with an adjusting piston 35 at the other end, which slides in the adjusting cavity 31 of the fixed column 25, and the heat-conducting fins 33 on the outer periphery of the fixed column 25 transfer the temperature to the expansion rubber sleeve 30 in the dynamic cavity 32. The expansion rubber sleeve 30 is deformed by heat and squeezes the gas in the dynamic cavity 32, pushing the adjusting piston 35 through the air guide hole 34 to drive the adjusting rod 29 to slide, so that the adjusting block 26 moves in the adjusting slide 27, driving the composite shielding layer 24 to unfold from the rotating rod 23, thereby expanding the shielding area. This design utilizes the temperature response characteristics of the expansion rubber sleeve 30 to achieve automatic extension of the composite shielding layer 24 as the temperature rises, dynamically enhancing the magnetic field shielding capability, and solving the problem of reduced shielding effectiveness of traditional shielding layers due to material performance degradation at high temperatures. At the same time, the thermal fins 33 accelerate temperature conduction, making shielding adjustment more timely, and the torsion spring ensures that the composite shielding layer 24 is automatically retracted when the temperature drops, forming a dynamic adaptive shielding system, which improves the electromagnetic compatibility and stability of the connector in different temperature environments.
