Description

Technical Field

[0001] This invention relates to the field of cable testing technology, and more specifically to a switching device and a cable performance testing apparatus. Background Technology

[0002] The electrical performance of wires and cables directly affects their use, so existing technologies require performance testing of cables, typically including DC resistance testing, voltage testing, and insulation resistance testing. Weapon systems, in particular, have even higher requirements for cable performance, and the control cable networks within these systems require automated testing of the performance of each branch. However, automated testing equipment is generally generic, and the test interface connectors are generic electrical connectors. In contrast, control cable networks have numerous connectors, complex wiring relationships, and diverse types. To ensure that the automated testing equipment is compatible with the connectors of each branch of the cable network and can perform functional tests on all branch wiring harnesses according to a specific testing procedure, a connection and interconnection relationship needs to be established between the control cable network and the automated testing equipment, especially for performance testing of large-scale control cable networks.

[0003] However, the existing adapters in related technologies cannot meet the testing needs. Therefore, it is necessary to design a test adapter that is both easy to use and versatile to meet the requirements of automated testing of mass-produced products. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a switching device and a cable performance testing apparatus, which ensures the functionality and convenience of the switching device while achieving versatility and meeting the requirements for automated testing of mass-produced products.

[0009] The housing is provided with mounting positions that match the plug-type electrical connector and the socket-type electrical connector one by one. The socket-type electrical connector is mounted on the housing through the mounting positions. The plug-type electrical connector can switch between being mounted in the mounting positions and being pulled out of the mounting positions and connected to the socket-type cable to be tested.

[0010] The connecting harness is located inside the housing and is electrically connected to the first socket group and the second socket group, as well as to the first socket group and the plug group, according to the set connection relationship.

[0011] The first socket group and the plug group are located on different sides of the housing, and the second socket group and the first socket group are located on different sides of the housing.

[0012] In some embodiments, the adapter further includes at least one plug securing component for securing at least a portion of the plug-type electrical connectors in the plug assembly;

[0013] The plug fixing assembly includes a detachable or snap-fit ​​fixing seat and a clamping seat. The fixing seat is located in the mounting position of the housing for installing a plug-type electrical connector. Both the fixing seat and the clamping seat have a central hole, and the fixing seat and the clamping seat are fitted together. The plug-type electrical connector passes through the central hole of the clamping seat and is connected and fixed to the clamping seat.

[0014] In some embodiments, the clamping seat includes a sleeve and a limiting flange connected to one end of the sleeve. A stop block is also provided on the outer ring surface of the sleeve. Along the axial direction of the clamping seat, the stop block and the limiting flange are spaced apart.

[0015] The fixing seat is provided with a connecting edge that is fixed to the housing. The wall of the central hole of the fixing seat is provided with a receiving groove that runs through the axis and matches the stop block. The axial length of the receiving groove is not greater than the axial distance between the stop block and the limiting flange.

[0016] In some embodiments, the clamping seat further includes a support bracket connected to the limiting flange, and the support bracket and the sleeve are respectively located at the two ends of the limiting flange along the axial direction of the clamping seat; the support bracket is connected and fixed to the plug-type electrical connector passing through the central hole of the clamping seat.

[0017] In some embodiments, the support bracket is an arc-shaped piece, the inner diameter of which is the same as the diameter of the central hole of the clamping seat, and the arc-shaped piece is coaxially arranged with the clamping seat;

[0018] The central angle of the arc-shaped piece is 120° to 180°.

[0019] In some embodiments, the enclosure includes at least one adapter box unit, the adapter box unit including an enclosure frame, a front panel and a rear panel, the first socket group being disposed on the rear panel, and the plug group and the second socket group being disposed on the front panel.

[0020] In some embodiments, the front panel has grips at the top and bottom, and / or the side of the housing has grips.

[0021] Based on the same inventive concept, the present invention also provides a cable performance testing device, comprising,

[0022] The aforementioned adapter equipment;

[0023] The testing equipment is equipped with multiple socket-type electrical connectors of the same model and specifications;

[0024] The adapter cable assembly includes multiple adapter cables, one end of which is provided with a plug-type electrical connector that matches the socket-type electrical connector of the test equipment, and the other end is provided with a plug-type electrical connector that matches the plug-type electrical connector of the first socket assembly.

[0025] In some embodiments, the socket-type electrical connector of the first socket group is the same as the socket-type electrical connector of the test equipment.

[0026] In some embodiments, the cable performance testing device further includes an operating table, the surface of which is provided with an installation area for placing the adapter and a testing area for placing the cable to be tested.

[0027] The operating platform is equipped with a limiting platform for limiting the outer side of the adapter, and the limiting platform surrounds the installation area.

[0028] As can be seen from the above technical solution, the adapter provided by the present invention includes a plug group, a first socket group, a second socket group, a housing, and a connecting wire harness. The plug group includes various plug-type electrical connectors of different models and specifications, which can be used to connect with the socket-type cable under test. The second socket group includes various socket-type electrical connectors of different types and specifications. Since the connectors in both the plug group and the second socket group have multiple models, specifications, quantities, and shapes, i.e., the mating ends of various electrical connectors are integrated on the housing, this adapter can be used for connecting cables under test with different structures. The connection is transmitted to automated testing equipment through the corresponding electrical connection of the first socket group. Specifically, the first socket group includes multiple conventionally used socket-type electrical connectors. Since the first socket group uses conventionally used electrical connectors as the output end of the adapter, the adapter is easily connected to the testing equipment. The enclosure has mounting positions that match the plug-type and socket-type electrical connectors one by one. The socket-type connectors are mounted on the enclosure through these mounting positions. The plug-type connectors can be switched between being in the mounting position and being pulled out of the mounting position to connect to the socket-type cable under test. That is, when not in use, the plug-type connectors are in the mounting position; when testing a cable with a socket is required, the corresponding plug-type connector can be pulled out to achieve connection. The connecting wire harness is located inside the enclosure and is electrically connected to the first socket group and the second socket group, as well as to the plug group, according to a set connection relationship, achieving point matching between the input and output ends. The first socket group and the plug group are located on different sides of the enclosure, and the second socket group and the first socket group are located on different sides of the enclosure for easy management and quick connection, which helps improve testing and production efficiency.

[0029] In summary, this invention integrates plug-type and socket-type electrical connectors, simultaneously meeting the testing requirements of both plug-type and socket-type cables. Based on the model and specifications of each connector on the cable network, functional adapter box modules can be flexibly combined to form products capable of automated connection performance testing for large-volume products. Operation is simple and convenient. During actual cable product testing, as long as the electrical connectors of each branch of the cable network are correctly aligned with the connectors of the plug group and the second socket group, and the testing equipment is connected through the first socket group, the electrical performance of the entire cable network can be tested for continuity and insulation according to a specific software process. This is suitable for automated testing of large-volume cable network performance. The use of this adapter is time-saving, labor-saving, and easy to operate, improving production efficiency.

[0042] To enable those skilled in the art to better understand this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Currently, weapon systems employ complex cable network connections with numerous structural branches and a wide variety of electrical connectors. To address the technical limitations of existing technologies in achieving universal cable testing, this invention provides a switching device and a cable performance testing apparatus. This ensures both the functionality and convenience of the switching device while achieving universality, meeting the requirements for automated testing of mass-produced products. The following two specific embodiments illustrate the invention in detail:

[0044] Example 1

[0045] like Figures 1-9 As shown, this embodiment provides an adapter device, including a plug group 100, a first socket group 200, a second socket group 300, a housing 400, and a connecting harness. The plug group 100 includes various plug-type electrical connectors of different models and specifications, which can be used to connect with the socket-type cable under test. The second socket group 300 includes various socket-type electrical connectors of different types and specifications. Since the electrical connectors of the plug group 100 and the second socket group 300 are provided with various models, specifications, quantities, and shapes, that is, the mating ends of various electrical connectors are integrated on the housing 400, this adapter device can be used for the conversion of cables under test with different structures, and transmits the connection to the automated testing equipment through the corresponding electrical connection of the first socket group 200. Specifically, the first socket group 200 includes multiple conventionally used socket-type electrical connectors. Since the first socket group 200 uses conventionally used electrical connectors as the output end of the adapter device, the adapter device is easy to connect to the testing equipment. The enclosure 400 has mounting positions that mate with both plug-type and socket-type electrical connectors. The socket-type connectors are mounted on the enclosure 400 via these mounting positions. The plug-type connectors can be switched between being in the mounting position and being extended to connect to the socket-type cable under test. When not in use, the plug-type connector is in the mounting position; when testing a cable with a socket is required, the corresponding plug-type connector can be extended for connection. The connecting harness is located inside the enclosure 400 and is electrically connected to the first socket group 200 and the second socket group 300, as well as to the first socket group 200 and the plug group 100, according to a pre-defined connection relationship, achieving point matching between input and output terminals. The first socket group 200 and the plug group 100 are located on different sides of the enclosure 400, and the second socket group 300 and the first socket group 200 are located on different sides of the enclosure 400 for ease of management and quick connection, thus improving testing and production efficiency.

[0046] In summary, this invention integrates plug-type and socket-type electrical connectors, simultaneously meeting the testing requirements of both plug-type and socket-type cables. Based on the model and specifications of each connector on the cable network, functional adapter box modules can be flexibly combined to form products capable of automated connection performance testing for large-volume products. Operation is simple and convenient. During actual cable product testing, as long as the electrical connectors of each branch of the cable network are correctly aligned with the connectors of plug group 100 and the second socket group 300, and the testing equipment is connected through the first socket group 200, the electrical performance of the entire cable network can be tested for continuity and insulation according to a specific software procedure. This is suitable for automated testing of large-volume cable network performance. The use of this adapter is time-saving, labor-saving, and easy to operate, improving production efficiency.

[0047] Because the cable network branch structure of the product under test has socket-type connectors, these connectors need to be mated with plug-type connectors on the adapter device for testing. However, since the plug-type connectors themselves do not have a connector base, they cannot be directly connected and fixed to the housing 400. In some embodiments, the plug-type connectors of the plug group 100 can be directly led out from the mounting position and suspended on the housing 400. For better management and to avoid affecting the insertion and use of the second socket group 300, as a preferred embodiment, the adapter device also includes at least one plug fixing assembly 500 for fixing at least some of the plug-type connectors in the plug group 100. The plug fixing assembly 500 includes a fixing seat 510 and a clamping seat 520 that can be detachably connected or snapped together. The fixing seat 510 is located in the mounting position of the housing 400 for installing the plug-type connector. Both the fixing seat 510 and the clamping seat 520 have a central hole, and the fixing seat 510 and the clamping seat 520 are fitted together. The plug-type connector passes through the central hole of the clamping seat 520 and is connected and fixed to the clamping seat 520.

[0048] It should be noted that while this embodiment does not limit the size specifications of the plug-type electrical connectors, in order to cover as many types and specifications of electrical connectors as possible for the cable under test, the plug-type electrical connectors in the plug assembly 100 are diverse in type and size, including but not limited to multiple plug-type electrical connectors of the same type but different sizes, and multiple plug-type electrical connectors of different types. When the plug-type electrical connector itself is large, it is generally also heavy. In this case, the plug fixing component 500 may not be used to avoid return and pull-out actions, thereby improving the connection efficiency.

[0049] As described above, this embodiment does not specifically limit the cooperation method between the clamping seat 520 and the fixing seat 510. Specifically, a detachable connection or a snap-fit ​​structure can be adopted. For example, in some embodiments, the clamping seat 520 and the fixing seat 510 are detachably connected by bolts. In order to simplify the operation of removing the clamping seat 520 to pull out the plug-type electrical connector, in some embodiments, a snap-fit ​​structure can be provided on the outer peripheral surface of the fixing seat 510. The snap-fit ​​can be opened and closed by providing a slot for the snap-fit ​​in the clamping seat 520 or by directly providing a snap-fit ​​positioning structure on the fixing seat 510, thereby axially limiting the clamping seat 520 and fixing the plug-type electrical connector on the fixing seat 510.

[0050] As a preferred embodiment, such as Figures 7-9 As shown, the clamping seat 520 includes a sleeve 521 and a limiting flange 522 connected to one end of the sleeve 521. A stop block 523 is also provided on the outer ring surface of the sleeve 521. Along the axial direction of the clamping seat 520, the stop block 523 and the limiting flange 522 are spaced apart. Figures 4-6 As shown, the fixed seat 510 is provided with a connecting edge 511 that is fixed to the housing 400. The central hole of the fixed seat 510 is provided with a receiving groove 512 that runs through the axis and matches the stop block 523. The axial length of the receiving groove 512 is not greater than the axial distance between the stop block 523 and the limiting flange 522. The clamping seat 520 and the fixed seat 510 are fitted together by aligning the stop block 523 and the receiving groove 512 and pushing the clamping seat 520 inward. Then, the clamping seat 520 is rotated at a certain angle so that the stop block 523, which extends out of the end of the receiving groove 512, is deviated from the position of the receiving groove 512. This makes the two end faces of the fixed seat 510 located between the stop block 523 and the limiting flange 522, thereby achieving the axial positioning of the clamping seat 520 on the fixed seat 510. When it is necessary to remove the clamping seat 520 and the plug-type electrical connector fixed by the clamping seat 520, simply rotate the clamping seat 520 to align the receiving groove 512 and the stop 523, and the clamping seat 520 can be pulled out axially.

[0051] In order to facilitate the removal of the clamping seat 520 from the fixed seat 510, in a preferred embodiment, a limiting block 513 is provided on both sides of the receiving groove 512 along the circumference of the fixed seat 510, and the relative central angle distance between the limiting block 513 and the receiving groove 512 is less than 90°.

[0052] This embodiment does not impose specific limitations on the connection and fixing of the fixing base 510 and the housing 400. For example, welding, riveting and other connection processes can be used.

[0053] This embodiment does not limit the connection and fixing method between the clamping base 520 and the plug-type electrical connector. In some embodiments, at least three elastic pieces can be provided on the wall of the central hole of the clamping base 520 at circumferential intervals, so as to match the size of the plug-type electrical connector or the size of the connecting wire harness connected to it of different sizes, thereby achieving clamping and positioning, so that the clamping base 520 and the plug-type electrical connector do not have relative axial displacement.

[0054] To simplify the structure, in this embodiment, the clamping base 520 further includes a support bracket 524 connected to the limiting flange 522. Along the axial direction of the clamping base 520, the support bracket 524 and the sleeve 521 are located at opposite ends of the limiting flange 522. The support bracket 524 is connected and fixed to a plug-type electrical connector that passes through the central hole of the clamping base 520. The support bracket 524 and the plug-type electrical connector can be connected and fixed using adhesive, clamps, ropes, or other structures.

[0055] To stably support and fix the plug-type electrical connector, in a preferred embodiment, the support bracket 524 is an arc-shaped piece. The inner diameter of the arc-shaped piece is the same as the diameter of the central hole of the clamping seat 520, and the arc-shaped piece and the clamping seat 520 are arranged coaxially. To avoid relative displacement between the arc-shaped piece and the plug-type electrical connector, preferably, the central angle of the arc-shaped piece is 120°-180°.

[0056] This embodiment does not specifically limit the structure of the housing 400, as long as it can meet the arrangement of the plug group 100, the first socket group 200 and the second socket group 300, as well as the arrangement of the internal wiring harness. In order to facilitate the management of all electrical connectors and arrange them in an orderly and regular manner, as one implementation method, for ease of handling, the housing 400 includes at least one adapter box unit 410. The adapter box unit 410 includes the housing 400 frame, a front panel 420 and a rear panel 430. The first socket group 200 is located on the rear panel 430, and the plug group 100 and the second socket group 300 are located on the front panel 420.

[0057] It should be noted that when adapting to a wider range of cable testing and adapter needs, the total number of electrical connectors required will inevitably increase. To facilitate better categorization, zoning, and transportation, when there are two or more adapter box units 410, connectors of similar types or the same type but different sizes should be grouped together in one adapter box unit 410 to avoid connection confusion. For example, ... Figure 1 As shown, the number of adapter box units 410 can be two, or as... Figure 2 As shown, the number of adapter box units 410 can be four. This embodiment does not impose a specific limit and can be adjusted according to actual needs.

[0058] This embodiment does not specifically limit the structure of the box 400 frame. For example, in some embodiments, the box 400 frame may have an integrally formed upper cover plate, lower cover plate, left side plate and right side plate. In some embodiments, the box 400 frame may also include a detachably connected upper cover plate, lower cover plate, left side plate and right side plate. That is, the front panel 420, the rear panel 430 and the upper cover plate, lower cover plate, left side plate and right side plate are all assembled by threaded connectors.

[0059] To facilitate handling and transportation, in this embodiment, grip portions 600 are provided at the top and bottom of the front panel 420, and / or on the sides of the housing 400. This embodiment does not limit the structure of the grip portions 600. For example, when the grip portion 600 is located on the front panel 420, it can be a handle structure. Further, the handle structure can be a rigid structure integrally formed with the front panel 420, or it can be a belt-type adjustable flexible handle. As another example, when the grip portion 600 is located on the left and right side panels of the housing 400, it can be a protruding rib formed on the left and right side panels, or it can be a groove structure, serving to strengthen the structure and act as a carrying handle.

[0060] The adapter device provided in this embodiment can fix different types of electrical connectors (socket-type electrical connectors and plug-type electrical connectors), such as universal Y2 type electrical connectors and high / low frequency mixing connectors, on the front panel 420 of the housing 400 according to the size and specifications of the connectors and a certain layout principle. The rear panel 430 uniformly houses Y2-65ZJBM electrical connectors. In use, the socket or plug on the front panel 420 is selected according to the connector model and specifications on the cable network branch of the product under test for mating. The output of the first socket group 200 on the corresponding rear panel 430, electrically connected via a connecting wire harness, is converted to a universal, common connector. Only a pre-defined connection structure is needed to connect the first socket group 200 and the test equipment.

[0061] Example 2

[0062] Based on the same inventive concept, this embodiment provides a cable performance testing device, including a testing device, a transfer cable group, and the transfer device of Embodiment 1; the testing device is equipped with multiple socket-type electrical connectors of the same model and specifications; the transfer cable group includes multiple transfer cables, one end of which is equipped with a plug-type electrical connector that matches the socket-type electrical connector of the testing device, and the other end is equipped with a plug-type electrical connector that matches the plug-type electrical connector of the first socket group 200. According to the connector type on the cable branch, the electrical connectors in the plug group 100 and the second socket group 300 are selected for insertion, and the universal connector on the automated testing device is connected to the electrical connector of the first socket group 200 through the transfer cable respectively. In this state, automated performance testing of the cable network can be performed.

[0063] This embodiment does not specifically limit the type and size of the socket-type electrical connectors of the first socket group 200 and the test equipment; any conventional and universal electrical connector can be used. To simplify the connection process and ensure that the plug structures at both ends of the adapter cable are identical, as a preferred embodiment, the socket-type electrical connectors of the first socket group 200 are the same as those of the test equipment. Of course, in other embodiments, the socket-type electrical connectors of the first socket group 200 and the test equipment can be different, for example, of the same type but different sizes. However, in this case, the two plug structures of the adapter cable will also be different, and it is necessary to confirm whether the insertion is correct during use.

[0064] For ease of operation, as a preferred implementation method, such as Figure 10 As shown, the cable performance testing device also includes an operating table 700, on which an installation area for placing adapters and a testing area for placing the cable to be tested are provided.

[0065] This embodiment does not specifically limit the arrangement of the operating table 700 on the housing 400 of the adapter. For example, in some embodiments, the bottom surface of the adapter can be bonded, welded, or bolted to the operating table 700. In some embodiments, in order to facilitate the maintenance and handling of the adapter, the operating table 700 is provided with a limiting platform for limiting the outer side of the adapter. The limiting platform surrounds the installation area and directly contacts the outer periphery of the housing 400. The housing 400 does not need to be connected and fixed to the operating table 700.

[0066] The operating table 700 has a table surface that is 1100mm long, 900mm wide, and 700mm high from the ground. The total height of the operating table 700 and the adapter after assembly is 1508mm. The adapter is positioned on the table using a combination of limit strips and head screws for positioning. During cable testing, the cable can be placed on the front of the testing operating table 700.

[0067] The cable performance testing device provided in this embodiment is used as follows: Place the cable network to be tested on the test area table, and connect it to the corresponding connector on the front panel 420 of the adapter box 400 according to the connector type on the cable branch. Connect the test adapter cable to the universal connector on the automated testing equipment and the Y2-65ZJBM socket on the rear panel 430 of the adapter box, respectively. Automated performance testing of the cable network can then be performed in this state.

[0068] In summary, the adapter and cable performance testing device provided by this invention are simple in materials, low in cost, and easy to operate. Based on the model and specifications of the electrical connectors on the cable network, functional adapters can be flexibly combined to form a complete device. During actual cable product testing, as long as the connectors of each branch of the cable network are correctly aligned with the electrical connectors on the front panel 420, and a specific software procedure is followed, the electrical performance of the entire cable network can be tested for continuity and insulation. It is suitable for automated testing of large batches of cable network performance. The use of this adapter saves time and labor, improving production efficiency.
