Description

Technical Field

[0001] This utility model relates to the field of signal processing box technology, and in particular to a connection mechanism for testing a signal processing box. Background Technology

[0002] In the research and development and production of modern electronic equipment, performance testing of signal processing boxes is crucial, and reliable connection mechanisms are a key factor in ensuring test accuracy and stability. Currently, BNC connectors, as a widely used signal connection component, are extensively used in the field of signal processing box testing. However, with the continuous development of technology and the increasing complexity of testing requirements, they have revealed many problems.

[0003] In high-density cabling testing scenarios, the spacing between conductors within BNC connectors is small. When a rapidly changing current passes through the conductors, an alternating magnetic field is generated, inducing signal voltages on adjacent conductors, resulting in crosstalk. This crosstalk is not only one of the main sources of electromagnetic compatibility (EMC) interference but also severely interferes with normal signal transmission, potentially leading to data errors, biased test results, and an inability to accurately reflect the true performance of the signal processing box. For example, when testing high-speed data transmission signal processing boxes, crosstalk may cause bit errors in the transmitted data, affecting the judgment of key indicators such as transmission rate and bit error rate.

[0004] In actual testing, signal processing boxes may be subjected to various vibrations and shocks, such as slight vibrations of the test equipment and accidental impacts from the external environment. Traditional BNC connectors have limited resistance to vibration and shock due to their structural design. When subjected to vibration, their connection points are prone to loosening, leading to signal transmission interruptions or instability. This not only affects the continuity of testing but may also result in the loss of important test data due to signal interruption, increasing testing costs and time. For example, in signal processing box testing in the aerospace field, loose BNC connectors under simulated flight vibration environments can cause test data loss, affecting the evaluation of equipment performance. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a connection mechanism for testing a signal processing box, which aims to improve the crosstalk problem between wires and the problem that the connection mechanism is prone to loosening when subjected to vibration or impact in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a connection mechanism for testing a signal processing box, comprising an outer shell, an insulating ring installed inside the outer shell, a central conductor installed inside the insulating ring, a ferrule installed at one end of the outer surface of the outer shell, a sealing ring installed at the other end of the outer surface of the outer shell, a tail cover installed on the outer surface of the sealing ring, a separation mechanism provided inside the sealing ring, and an anti-detachment mechanism provided outside the sealing ring;

[0007] The separating mechanism includes an outer ring, which is installed on the inner surface of the sealing ring. A fixing ring is installed between the two outer rings. An inner ring is installed on the side surface of the fixing ring, and an adjusting seat is installed on the outer surface of the fixing ring.

[0008] As a further description of the above technical solution: the anti-detachment mechanism includes a sliding groove, which is formed on the outer surface of the sealing ring, and an anti-detachment block is slidably connected to the inner wall of the sliding groove.

[0009] As a further description of the above technical solution: the anti-detachment block is trapezoidal, and the outer surface of the anti-detachment block is provided with anti-slip texture.

[0010] As a further description of the above technical solution: one end of the sleeve is provided with an anti-disengagement hole, and the position of the anti-disengagement hole corresponds to the anti-disengagement block.

[0011] As a further description of the above technical solution: a limit ring is installed on the outer surface of the sealing ring.

[0012] As a further description of the above technical solution: one end of the regulating seat passes through the sealing ring and is slidably connected to the outer surface of the limiting ring.

[0013] As a further description of the above technical solution: a limiting groove is provided inside the regulating seat, and the size of the limiting groove corresponds to the limiting ring.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, a fixing ring between two outer rings initially positions the wires, preventing them from tangling and reducing the likelihood of crosstalk. The adjusting seat on the outer surface of the fixing ring can slide on the outer surface of the limiting ring, flexibly adjusting the wire spacing according to actual needs, further optimizing the anti-crosstalk effect. Furthermore, the limiting ring and the limiting groove inside the adjusting seat cooperate to lock the adjusted wire position, preventing secondary tangling and ensuring the accuracy of signal transmission, effectively improving signal quality during signal processing box testing.

[0016] In this invention, a sliding groove is formed on the outer surface of the sealing ring, and the anti-detachment block that matches it is trapezoidal and has anti-slip texture on its outer surface. When the outer shell is properly aligned with the signal processing box, the anti-detachment block can slide into the anti-detachment hole at one end of the sleeve. The trapezoidal design ensures a tight fit with the anti-detachment hole, and the anti-slip texture increases friction. Even in complex vibration environments, it can prevent the connection mechanism from loosening, ensuring the stability of signal transmission and avoiding signal interruption or transmission abnormalities due to loosening. This provides a reliable connection guarantee for the testing of the signal processing box. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 An embodiment of this utility model provides a connection mechanism for testing a signal processing box, including an outer shell 1, an insulating ring 2 installed inside the outer shell 1, a center conductor 3 installed inside the insulating ring 2, a ferrule 4 installed at one end of the outer surface of the outer shell 1, a sealing ring 5 installed at the other end of the outer surface of the outer shell 1, a tail cover 6 installed on the outer surface of the sealing ring 5, a separation mechanism 7 provided inside the sealing ring 5, and an anti-detachment mechanism 8 provided outside the sealing ring 5.

[0024] The separating mechanism 7 includes an outer ring 701, which is installed on the inner surface of the sealing ring 5. A fixing ring 702 is installed between the two outer rings 701. An inner ring 703 is installed on the side surface of the fixing ring 702. An adjusting seat 704 is installed on the outer surface of the fixing ring 702.

[0025] Specifically, the outer ring 701 and inner ring 703 provide installation positions. The wire retainer 702 is used to limit the position of the wire. The adjusting seat 704 is used to adjust the position of the wire retainer 702.

[0026] The anti-detachment mechanism 8 includes a sliding groove 801, which is formed on the outer surface of the sealing ring 5, and an anti-detachment block 802 is slidably connected to the inner wall of the sliding groove 801.

[0027] One end of the sleeve 4 has an anti-disengagement hole 401, and the position of the anti-disengagement hole 401 corresponds to the anti-disengagement block 802.

[0028] The anti-detachment block 802 is trapezoidal, and the outer surface of the anti-detachment block 802 is provided with anti-slip texture 803.

[0029] Specifically, the anti-detachment hole 401 is used to cooperate with the anti-detachment block 802 to achieve a self-locking effect. The anti-slip texture 803 is used to increase the friction between the anti-detachment hole 401 and the anti-detachment block 802.

[0030] A limit ring 501 is installed on the outer surface of the sealing ring 5.

[0031] One end of the regulating seat 704 passes through the sealing ring 5 and is slidably connected to the outer surface of the limiting ring 501.

[0032] The control seat 704 has a limiting groove 705 inside, and the size of the limiting groove 705 corresponds to the limiting ring 501.

[0033] Specifically, the limiting ring 501 engages with the limiting groove 705 to regulate and stabilize the position of the regulating seat 704.

[0034] Working principle: In actual use, the wire to be connected is first passed through the tail cover 6, the sealing ring 5, and the wire fixing ring 702 of the separation mechanism 7, and finally connected to the center conductor 3. After completion, the outer shell 1 is docked with the signal processing box. During the docking process, the ferrule 4 installed on one end of the outer surface of the outer shell 1 plays a role in initial positioning and fixing.

[0035] After connecting to the signal processing box, the testing phase begins. If the spacing between the wires in the connection mechanism is too small, a rapidly changing current flowing through the wires will generate an alternating magnetic field, inducing signal voltages on adjacent wires, i.e., crosstalk. Crosstalk is not only a major cause of electromagnetic compatibility (EMC), but it also interferes with normal signal flow, potentially causing data errors. This invention addresses this problem by separating the wires. By passing the wires through the fixing ring 702 between the two outer rings 701, the wires are initially positioned, preventing them from tangling and reducing the possibility of crosstalk. Then, according to actual needs, the adjusting seat 704 is rotated, allowing it to slide on the outer surface of the limiting ring 501, thus adjusting the wire spacing and further optimizing the anti-crosstalk effect. Simultaneously, the limiting ring 501 can lock the adjusted wire position, preventing secondary tangling.

[0036] Considering that the working environment of the connecting mechanism is subject to vibration, which in turn affects the stability of the connection, this utility model addresses this problem by adding an anti-detachment mechanism 8. When the outer shell 1 is docked with the signal processing box, the anti-detachment block 802 can slide through the sliding groove 801 to the anti-detachment hole 401 opened at one end of the sleeve 4. Furthermore, its trapezoidal design and anti-slip texture 803 enable the anti-detachment block 802 to fit tightly with the anti-detachment hole 401, preventing the connecting mechanism from loosening when subjected to vibration or impact.

[0037] Furthermore, the tail cover 6 installed on the outer surface of the sealing ring 5 serves two purposes: firstly, it protects the internal connecting components from dust, moisture, and other impurities entering the connecting mechanism and affecting signal transmission quality; secondly, the tail cover 6 also provides some protection for the wires, preventing them from being worn down by the external environment. Simultaneously, the insulating ring 2 installed inside the outer shell 1 effectively isolates the central conductor 3 from the outer shell 1, preventing safety issues such as leakage and ensuring the safety and stability of the signal processing box during testing.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
