Description

Technical Field

[0001] The present invention relates to the technical field of data bus coupler cable design, in particular to a combined coupler cable and a product testing system. Background Art

[0002] The 1553B data bus coupler (hereinafter referred to as the coupler) is primarily used to couple signals transmitted on the bus to branch lines, allowing terminal devices to obtain information on the bus. It suppresses common-mode signals and isolates branch lines, making it a crucial electrical component in 1553B data bus networks. Couplers are categorized by structural form into box and wire types. The core features of these two types of couplers are identical, differing primarily in their presence or absence of wires and their appearance. The coupler body utilizes a monolithic structure, integrating a coupling transformer, isolation resistor, and other components. Based on their intended use, the coupler is divided into two interfaces: the bus end (BUS end) and the stub end (SUB end). Box couplers utilize standard connectors at both the bus and stub ends of the coupler body. Wire couplers (hereinafter referred to as wire couplers) utilize cables of a specified length welded to both the bus and stub ends of the coupler body, resulting in a single, integrated plastic package.

[0003] The 1553B data bus coupler cable (hereinafter referred to as the coupler cable) is a specialized cable developed primarily for testing 1553B data bus products. It primarily includes a coupler, a certain length of 1553B cable, and connectors at both ends of the cable. Coupler cables used in specific scenarios must be customized based on user needs. The design process begins with clarifying the detailed requirements for the coupler cable, then drawing the design drawings and handing them over to the production unit for assembly. During production, equipment matching and missing parts replenishment for different specifications and customization requirements are required. This presents a challenge in the integrated design, production, and supply guarantee of specialized cables, resulting in a long development cycle for coupler cables, a very low degree of standardization, and high operating costs, including inventory management.

[0028] The present invention proposes a combined coupler cable based on a linear coupler, such as Figure 5As shown, according to a specific embodiment of the present invention, a combined coupler cable is provided, the coupler cable including a universal coupler cable, a dedicated stub cable and a universal transition cable;

[0029] The universal coupler cable comprises a coupler body and a universal main line cable and a universal stub cable connected to the coupler body;

[0030] One end of the dedicated short stub cable is connected to the universal short stub cable, and the other end is connected to the product end or the test end, and is used to electrically connect the coupler body to the product end and to electrically connect the coupler body to the test end;

[0031] Universal adapter cables include universal main line adapter cables and universal short stub adapter cables. Universal main line adapter cables are used to extend universal main line cables to electrically connect two coupler bodies. Universal short stub adapter cables are used to extend dedicated short stub cables to electrically connect the coupler body and the product end or the coupler body and the test end.

[0032] This configuration method provides a modular coupler cable. By rationally dividing the entire cable into three parts: a universal coupler cable, a dedicated short-stub cable, and a universal adapter cable, the modular design of the entire cable is achieved. This modular design then meets the requirements of rapid manufacturing and cost reduction through combined use. Universal coupler cables and universal adapter cables are designed universally and a certain number of finished parts are stocked. Each custom order only requires the design, equipment, and manufacturing of the dedicated short-stub cable, which is the specialized component required. The entire cable is then formed by combining and cascading the modules. This division method standardizes the design process of the coupler cable, improving the "three-dimensional" level of the coupler cable. By leveraging the reusability of the universal modules, the development cycle of the entire coupler cable is shortened, meeting the diverse needs of rapidly building 1553B data bus tests in various scenarios, while also reducing the cost of the coupler cable. Compared to the prior art, the technical solution of the present invention can address the technical issues of the prior art, such as the long development cycle, low degree of universalization, and high cost of use, including inventory management, for coupler cables.

[0033] In the present invention, the universal main line cable is a data bus, such as a 1553B data bus. For the convenience of description, the following description of the combined coupler cable is specifically described using the 1553B data bus as an example. The universal coupler cable in the combined coupler cable is the key, responsible for connecting the dedicated short-line cable at the test end and the product end to achieve the electrical connection of the 1553B data bus product test. In order to meet the A / B dual redundant interface requirements of the 1553B data bus, the universal coupler cable integrates the two coupler bodies together, such as Figure 1A 、 Figure 1B and Figure 1C As shown, according to the number of bus terminations, there are three types: bus termination, bus single-side termination and bus unterminated. Different bus termination numbers are convenient for use and cascade expansion.

[0034] In order to enable the universal main line cable to be electrically connected to different types of product ends and test ends, thereby improving its versatility, the present invention converts the dedicated interfaces of the product end and the test end into a unified interface through a dedicated short stub cable, and then electrically connects to the universal main line cable through this unified interface. As a specific embodiment of the present invention, the universal main line cable includes a universal main line cable body connected to a coupler body and a first connector connected to its free end, and the dedicated short stub cable includes a dedicated short stub cable body connected to the product end or the test end and a second connector connected to its free end. The dedicated short stub cable body and the universal main line cable body are electrically connected through the cooperation of the first connector and the second connector.

[0035] Furthermore, in the present invention, the universal main line adapter cable includes a universal main line adapter cable body and second connectors connected at both ends thereof, and the second connectors at both ends of the universal main line adapter cable body respectively cooperate with a first connector at a free end of the universal main line cable body.

[0036] In addition, the universal short stub adapter cable includes a universal short stub adapter cable body and a first connector and a second connector connected at both ends thereof. One end of the short stub adapter cable body is matched with the first connector at the free end of the universal main line cable body through the second connector at its end, and the other end is matched with the second connector at the free end of the special short stub cable body through the first connector at its end.

[0037] As a specific embodiment of the present invention, the first connector is a CJ70 connector, and the second connector is a PL75-47 connector. Based on this embodiment, the structures of the dedicated short stub cable, the universal short stub adapter cable, and the universal main line adapter cable are as follows: Figure 2 、 Figure 3 and Figure 4 With this configuration, the dedicated stub cable converts the interfaces of the test end and product end into PL75-47 connectors, which can be docked with the CJ70 connector on the external interface of the universal coupler cable, thereby enabling quick connection between different test ends and different product ends and the universal coupler cable.

[0038] To facilitate a clearer understanding of the combined coupler cable provided by the present invention, the following will use actual application examples to explain in detail the method of using the combined coupler cable. Those skilled in the art will appreciate that this example is only for the purpose of facilitating a clearer understanding of the combined coupler cable provided by the present invention and does not constitute any technical limitation thereto.

[0039] When applying the combined coupler cable proposed in the present invention, first, determine whether it is necessary to cascade the universal coupler cable according to the distance requirements between the test end and the product end in the usage scenario, and determine the model and quantity of the universal coupler cable. Taking the linear coupler cable as the universal coupler cable as an example, the interface connectors of the universal main line cable end and the universal short stub cable end of the linear coupler cable are unified as CJ70 connectors, wherein the length of the universal main line cable 1553B cable is 10cm, and the length of the universal short stub cable 1553B cable is 100cm. The two universal short stub cables are separated on both sides of the coupler body, and the total length of the cable part of the universal coupler cable is 200cm. Secondly, according to the specific test interfaces of the test end and the product end, a special short stub cable is produced, and the interfaces of the test end and the product end are uniformly converted to PL75-47 connectors with a length of 50cm through the special short stub cable. Then, according to the cable usage length and the 1553B communication rate, determine whether it is necessary to use a universal adapter cable to extend the special short stub cable or the universal main line cable. When using, simply connect the three cable modules to the corresponding interfaces. The following are two application examples.

[0040] In a certain type of general-purpose test equipment, a single-channel dual-redundant A / B 1553B communication test is required for the product under test. The communication rate is 1M, and the test equipment and the product under test are placed 10 meters apart. This type of coupler cable design includes: 1 bus-terminated universal coupler cable, 200cm long; 1 test-side dedicated short stub cable, 50cm long; 1 product-side dedicated short stub cable, 50cm long; and 2 universal short stub adapter cables, 350cm long. Please refer to the connection relationship between the cable modules for details. Figure 5 .

[0041] In a certain type of general-purpose test equipment, a single-channel dual-redundant A / B 1553B communication test is required for the product under test. The communication rate is 4M, and the test equipment and the product under test are placed 50 meters apart. This type of coupler cable design includes: two universal coupler cables with single-side bus termination, each 200cm long; one short stub cable for the test end, each 50cm long; and one short stub cable for the product end, each 50cm long; and two universal main line adapter cables, each 350cm long. For the connection relationship between the cable modules, please refer to Figure 6 .

[0042] According to another aspect of the present invention, a product testing system is provided, comprising the aforementioned combined coupler cable. Because the combined coupler cable improves the versatility of universal cable modules, shortens the development cycle of the entire coupler cable, and reduces the cost of the coupler cable, its application in a product testing system can significantly improve the versatility of the product testing system and reduce testing costs.

[0043] In summary, the present invention provides a modular coupler cable and product testing system. The coupler cable achieves modular design by rationally dividing the entire cable into three parts: a universal coupler cable, a dedicated short stub cable, and a universal adapter cable. This modular design allows for rapid manufacturing and cost reduction through combined use. Universal coupler cables and universal adapter cables are designed universally and a certain number of finished parts are stocked. Each time, only the specialized part, the dedicated short stub cable, required for customization, needs to be designed, equipped, and manufactured. The entire cable is then formed by combining and cascading the various modules. This division method standardizes the design process for coupler cables, improving the "three-dimensional" ("three-dimensional") level of coupler cables. By utilizing the reusability of universal modules, the development cycle of the entire coupler cable is shortened, meeting the diverse needs of rapidly building 1553B data bus tests in various scenarios, while also reducing the cost of using the coupler cable. Compared to the prior art, the technical solution of the present invention can address the technical issues of the prior art, such as long development cycles, low universality, and high costs associated with inventory management, for coupler cables.

[0044] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0045] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0046] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
