Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a multicast measurement fixture. Background Technology

[0002] Multicast is a network technology that allows a single data source to send data packets to multiple destinations. By testing the performance of multicast, network bandwidth usage can be optimized. Supporting multicast functionality in a network typically requires network devices, especially routers and Layer 3 switches. When testing multicast functionality, the corresponding network devices need to be placed on a multicast measurement fixture for testing.

[0003] Current multicast measurement fixtures generally adopt a stepped integrated fixture. This type of fixture has fixed workstations, and the top workstation is too high, which makes multicast testing at high workstations inconvenient. The existing multicast measurement fixtures cannot add or remove workstations according to the needs of the product under test, resulting in a waste of resources on the multicast measurement fixture.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Figure 1 This is a front structural diagram of the test platform in a multicast measurement fixture according to an embodiment of the present invention, as shown below. Figure 1 As shown, the multicast measurement fixture includes a test platform. The top of the test platform is provided with an upper cover plate 7, and the bottom of the test platform is provided with a base plate 1. A support body is provided between the upper cover plate 7 and the base plate 1. The test platform is divided into multiple test positions. A power network port assembly is fixedly installed in each test position. The upper cover plate 7 is provided with a first detachable mechanism and / or the base plate 1 is provided with a second detachable mechanism 18. The first detachable mechanism is used to cooperate with the second detachable mechanism 18 of another test platform.

[0024] Understandably, this multicast measurement fixture comprises multiple layers of the test bench. Figure 4 This is a schematic diagram of a multicast measurement fixture according to an embodiment of the present invention. The following description uses a multicast measurement fixture including a three-layer test bench as an example to illustrate this embodiment. Figure 4As shown, the multicast measurement fixture includes a bottom test platform A, a middle test platform B, and a top test platform C. When the test platform is located at the top layer of the multicast measurement fixture, the top test platform C does not need to be equipped with a first detachable mechanism; it only needs to be equipped with a second detachable mechanism 18 on the base plate 1 to be assembled and disassembled with the lower test platform. When the test platform is located at the bottom layer of the multicast measurement fixture, the bottom test platform does not need to be equipped with a second detachable mechanism 18; it only needs to be equipped with a first detachable mechanism on the upper cover plate 7 to be assembled and disassembled with the upper test platform. When the test platform is located at the middle layer of the multicast measurement fixture, both the first detachable mechanism on the upper cover plate 7 and the second detachable mechanism 18 on the base plate 1 are required to facilitate simultaneous assembly and disassembly with both the upper and lower test platforms.

[0025] This embodiment provides a first detachable mechanism on the upper cover of the test platform of the multicast measurement fixture, a second detachable mechanism on the bottom plate of the test platform, and a power network port assembly fixedly installed in each test position. This allows the multicast measurement fixture to be assembled and spliced ​​using different test platforms, enabling the multicast measurement fixture to be dynamically adjusted according to the height of the tester. On the other hand, the number of test platforms in the multicast measurement fixture can also be dynamically adjusted according to the number of products to be tested, thereby improving the utilization rate of the test positions in the multicast measurement fixture.

[0026] Alternatively, the support structure may include, but is not limited to, the side plate 2, the intermediate support rod 9, the rear cover plate 8, and the back plate of the test bench. Figure 2 This is a schematic diagram of the back structure of the test platform in a multicast measurement fixture according to an embodiment of the present invention, with reference to... Figure 2 Preferably, the support includes side plates 2 disposed on both sides of the test platform. The top end of each side plate 2 is fixed to the two sides of the upper cover plate 7, and the bottom end of each side plate 2 is fixed to the two sides of the base plate 1. In this embodiment, the support serves to support the base plate and the upper cover plate, and also makes the structure of the multicast measurement fixture more robust.

[0027] Preferably, the bottom end of the side plate 2 has a disassembly hole 17 corresponding to the second detachable mechanism 18. This disassembly hole 17 can be used as a gripper by the operator when assembling different test benches.

[0028] Optionally, at least one of the power supply port components is fixedly installed within the test station. Figure 4 This is a schematic diagram of the structure of a multicast measurement fixture according to an embodiment of the present invention, as shown below. Figure 1 and Figure 4As shown, the power supply and network port assembly includes, but is not limited to, a power single plug 10, a network single plug 11, a power pair plug 13, and a network pair plug 12. The number of each power single plug 10, network single plug 11, power pair plug 13, and network pair plug 12 can be fixed inside the test bench according to the demand of the product under test.

[0029] In this embodiment, at least one power network port component is fixedly installed in the test position, which can meet the test requirements of different test products. When the test product only needs one set of power network port components for wiring, the test product can be placed in the test position with only one power network port component for testing. When the test product needs multiple sets of power network port components for wiring, the test product can be placed in the test position with multiple power network port components for testing. This embodiment can improve the practicality and compatibility of the multicast measurement fixture.

[0030] Optionally, the support structure includes multiple intermediate support rods 9, which are vertically arranged in the plane containing the base plate 1 and the upper cover plate 7. The top of each intermediate support rod 9 is fixed to the upper cover plate 7, and the bottom of each intermediate support rod 9 is fixed to the base plate 1. The support structure provided in this embodiment, by utilizing multiple intermediate support rods 9 vertically arranged in the plane containing the base plate 1 and the upper cover plate 7, can further enhance the robustness of the multicast measurement fixture.

[0031] Preferably, the plane formed by each intermediate support rod 9 is parallel to the plane of the rear cover plate 8. This design makes it easier to fix the power plug mounting plate 3 and the network port mounting plate 4 onto the intermediate support rod 9, and also makes it easier for testers to operate on the network port single plug 11 and network port double plug 12.

[0032] like Figure 1 As shown, a middle partition plate 5 can also be added to the side of each middle support rod 9. The middle partition plate 5 can serve as a support and also as a dividing line between different test positions. The top of the middle partition plate 5 is fixed to the upper cover plate 7 of the test platform, and the bottom of the middle partition plate 5 is fixed to the bottom plate 1 of the test platform. There are also various fixing methods, such as fixing with screws, fixing with holes and stoppers, pins, etc.

[0033] Optionally, screws are also included. The first detachable mechanism includes a first threaded hole built into the upper cover plate 7, and the second detachable mechanism 18 includes a second threaded hole built into the base plate 1. The test bench is fixed to another test bench by screws driven into the first threaded hole and the second threaded hole of the other test bench.

[0034] Optionally, bolts and nuts are also included. The first detachable mechanism includes a first through hole built into the upper cover plate 7, and the second detachable mechanism 18 includes a second through hole built into the base plate 1. The first through hole and the second through hole are engaged with each other by the bolts and nuts.

[0035] In other embodiments, the cooperation between the first detachable mechanism and the second detachable mechanism 18 can also be achieved by a slide rail. For example, a slide groove can be longitudinally provided on the bottom side of the base plate 1, and a ridge corresponding to the slide groove can be longitudinally provided on the upper surface of the upper cover plate 7. By sliding the slide rail, different test benches can be assembled or disassembled.

[0036] This embodiment provides multiple implementations of the first detachable mechanism and the second detachable mechanism, allowing users to choose freely according to their needs.

[0037] As an option, such as Figure 1 and Figure 4 As shown, a power plug mounting plate 3 and a network port mounting plate 4 are fixed on the intermediate support rod 9 in the opening direction of the test bench, and the power plug mounting plate 3 and the network port mounting plate 4 pass through each test position. Preferably, as... Figure 1 and Figure 4 As shown, multiple power plugs 10 are fixedly installed on the power plug mounting plate 3, and multiple network port plugs 11 are fixedly installed on the network port mounting plate 4. Specifically, each power plug 10 is fixedly installed in each test position on the power plug mounting plate 3, and each network port plug 11 is fixedly installed in each test position on the network port mounting plate 4.

[0038] In this embodiment, a power plug mounting plate 3 and a network port mounting plate 4 are fixed on the intermediate support rod 9 in the direction of the opening of the test bench. Multiple power plugs 10 are fixed on the power plug mounting plate 3, and multiple network port plugs are fixed on the network port mounting plate 4, so that each power plug and network port plug faces the opening of the test bench. This facilitates the plugging and unplugging of cables when performing multicast tests on network devices, making it easier for testers to operate and thus improving the practicality of the multicast measurement fixture.

[0039] As an option, such as Figure 2 As shown, the test stand also includes a rear cover plate 8, such as Figure 4 As shown, the test position is equipped with a rear plug-in network port pressure plate 6. The power plug 13 and the network port plug 12 are fixed to the inside of the rear cover plate 8 by the screws of the rear plug-in network port pressure plate 6.

[0040] like Figure 2As shown, the rear cover plate 8 is located on the back of the test bench. Preferably, the two ends of the rear cover plate 8 are fixedly installed with the side plates 2 on both sides of the test bench. The position of the rear cover plate 8 covers each test position. The power plug 13 and the network port plug 12 are provided on the inner side of the rear cover plate 8 at each test position.

[0041] In this embodiment, by setting a rear cover plate and fixing the power connector 13 and the network port connector 12 to the inner side of the rear cover plate 8 with screws on the rear network port clamping plate 6, the power connector 13 and the network port connector 12 can be more securely fixed. On the other hand, through holes can be drilled at the positions of the power connector 13 and the network port connector 12 on the rear cover plate so that when the device under test has bidirectional requirements for power supply and network port connection, the wires can pass through the through holes, further improving the practicality of the multicast measurement fixture.

[0042] like Figure 1 and Figure 4 As shown, optionally, product baffles 15 are provided on both sides of the test position, and each product baffle 15 is fixedly disposed on the upper surface of the base plate 1. Preferably, the planes on which the product baffles 15 are located are parallel to each other, and each product baffle 15 is vertically fixed to the upper surface of the base plate 1.

[0043] This embodiment, by setting product baffles on both sides of the test position, makes it easier for testers to find the placement of the product under test at a glance during multicast measurements, thereby improving the efficiency of multicast testing.

[0044] Optionally, the multicast measurement fixture includes multiple layers of the test bench, such as... Figure 1 , Figure 2 and Figure 4 As shown, the bottom plate 1 of the top-level test bench C, the top cover plate 7 and the bottom plate 1 of the middle-level test bench B, and the top cover plate 7 of the bottom-level test bench have through-type heat dissipation holes 16 and dust collection holes 14.

[0045] Figure 3 This is a top view of the test bench in a multicast measurement fixture according to an embodiment of the present invention, as shown below. Figure 3 As shown, when the test platform is located on the top layer of the multicast measurement fixture, the top cover plate 7 of the top test platform C does not have heat dissipation holes 16 and dust collection holes 14, keeping it as a complete plate to prevent dust or debris from falling into the multicast measurement fixture.

[0046] When the multicast measurement fixture includes multiple test benches, the bottom plate 1 of the top test bench C, the top cover plate 7 and the bottom plate 1 of the middle test bench B, and the top cover plate 7 of the bottom test bench are provided with through-type heat dissipation holes 16 so that the product under test at the test position can dissipate heat quickly during multicast testing.

[0047] Since the multicast measurement fixture in this embodiment of the utility model has an opening, dust will enter the interior of the test platform of the multicast measurement fixture from the opening. Through-type dust collection holes 14 are opened on the bottom plate 1 of the top test platform C, the top cover plate 7 and bottom plate 1 of the middle test platform B, and the top cover plate 7 of the bottom test platform to facilitate the cleaning of dust that enters the interior of the test platform.

[0048] like Figure 1 and Figure 2 As shown, it can be understood that in this embodiment, "through-type" means that the heat dissipation holes 16 and dust collection holes 14 located on different plates are interconnected in the longitudinal direction. Preferably, the size and shape of each heat dissipation hole 16 are the same.

[0049] Preferably, the front ends of the two side plates 2 are provided with corresponding grooves, and the power plug mounting plate 3 and the mesh port mounting plate 4 are fixedly installed in the grooves. The upper cover plate 7 protrudes from the positions of the power plug mounting plate 3 and the mesh port mounting plate 4 and has the dust collection hole 14. The bottom plate 1 protrudes from the corresponding positions of the power plug mounting plate 3 and the mesh port mounting plate 4 and has the dust collection hole 14 through it.

[0050] In this embodiment, the power plug mounting plate 3 and the network port mounting plate 4 are both fixedly installed in the groove, and the dust collection hole 14 is opened at a position protruding from the power plug mounting plate 3 and the network port mounting plate 4. This ensures that even if dust enters the test bench during multicast measurement, it will not affect the product under test in the test position, thus keeping the product under test clean and hygienic.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
