Description
Technical Field
[0001] This utility model relates to the field of multi-bus signal testing equipment, specifically a multi-bus signal tester. Background Technology
[0002] A multi-bus signal tester is a specialized device that integrates testing functions for multiple bus protocols. It is primarily used for simulating, analyzing, diagnosing faults, and recording data from signals at different bus interfaces in complex electronic systems. It is widely used in aerospace, automotive electronics, and military equipment, supporting synchronous or independent testing of multiple bus protocols to meet the demands of modern electronic systems for multi-bus compatibility and high reliability. Existing technologies for multi-bus signal testers still have certain drawbacks in use. Traditional multi-bus signal testers typically have many electronic modules inside, and the equipment generates a lot of heat during operation. Generally, the heat is dissipated to the outside through the heat dissipation vents. At the same time, external dust also enters the housing through the heat dissipation vents, and the electronic modules become covered with dust. This not only affects the heat dissipation efficiency of the equipment, but also causes internal dampness, reducing the service life of the equipment. Utility Model Content
[0003] The purpose of this invention is to provide a multi-bus signal tester to solve the problem mentioned in the background art that traditional multi-bus signal testers usually have many electronic modules inside, and the equipment generates a lot of heat during operation. Generally, the heat is discharged to the outside through the heat dissipation vents. At the same time, external dust will also enter the housing through the heat dissipation vents, and the electronic modules will be covered with dust. This not only affects the heat dissipation efficiency of the equipment, but also causes internal dampness and reduces the service life of the equipment.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-bus signal tester, comprising a multi-bus signal tester housing and a dust filter. An electronic testing module is located inside the housing, situated at the bottom of the inner end face of the front cover. A display screen, a bus interface, and a setting button are sequentially arranged on the outside of the front cover. Portable handles are located at the center of both sides of the housing. Heat dissipation vents are located at the rear ends of both sides of the housing, with the interior of the vents connected to a hollow layer. An assembly groove is located at the top of the hollow layer. Anti-slip pads are located at the four corners of the bottom of the housing.
[0005] In a further embodiment, a filter placement groove is provided at the rear end of the hollow layer, aligned with the heat dissipation vent. A dust filter is provided in the filter placement groove. The top of the dust filter is connected to the filter shaping frame by a buckle. A disassembly pinch piece is provided on one side of the top of the filter shaping frame, and the disassembly pinch piece is fixedly connected to the assembly slide by a limiting tooth and a limiting slot.
[0006] In a further embodiment, a sealing cover is provided at the position where the top surface of the front cover is aligned with the assembly slide groove, and the sealing cover and the assembly slide groove are slidably connected by an assembly slide bar.
[0007] In a further embodiment, the two sides inside the front cover are fixedly connected to the inner wall of the multi-bus signal tester housing via positioning inserts and positioning slots, and the positioning inserts and positioning slots are fixedly connected via locking bolts, which are located at the front end of both sides of the multi-bus signal tester housing.
[0008] In a further embodiment, the portable handle is connected to the middle of both sides of the multi-bus signal tester housing via an adjusting slider and an adjusting groove, and the portable handle and the adjusting slider are connected by rotation.
[0009] In a further embodiment, the dust filter is configured as a double-layer structure, and the dust filter is made of aluminum.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention features a double-layer dust filter, which effectively improves dust filtration and enables tiered interception. The outer filter layer removes large particles such as lint and debris, while the inner filter layer removes finer particles like dust and sand, resulting in higher filtration precision. This also reduces the clogging rate of individual filters, extending their lifespan. Furthermore, the dust filter is detachable, making it easier to disassemble and clean. Compared to traditional methods, it offers reusability, reducing long-term operating costs. Attached Figure Description

An electronic test module 11 is located inside the housing 1, at the bottom of the inner end face of a front cover 10. A display screen 14, a bus interface 15, and a setting button 16 are sequentially arranged on the outside of the front cover 10. Portable handles 2 are located at the middle of both sides of the housing 1. Heat dissipation vents 17 are located at the rear ends of both sides of the housing 1, and the interior of each vent 17 is connected to a hollow layer 21. The top of the 21 is provided with an assembly slide 7, and the four corners of the bottom of the multi-bus signal tester housing 1 are provided with anti-slip pads 18. The multi-bus signal tester housing 1 is used to seal and install the electronic test module 11 for protection. The display screen 14 is used to display test data. The bus interface 15 is used to connect the buses in each system. The setting button 16 is used to set the test program. The portable handle 2 is used to carry the multi-bus signal tester housing 1 by hand. The heat dissipation vent 17 is used for heat dissipation. The hollow layer 21 is used to increase the heat dissipation space inside the heat dissipation vent 17.
[0015] A filter placement groove 23 is provided at the rear end of the hollow layer 21, aligned with the heat dissipation vent 17. A dust filter 13 is installed in the filter placement groove 23. The dust filter 13 has a double-layer structure and is made of aluminum. The double-layer structure of the dust filter 13 can improve the dust filtration effect. The top of the dust filter 13 is connected to the filter shaping frame 3 by a buckle. A disassembly pinch 4 is provided on one side of the top of the filter shaping frame 3. The disassembly pinch 4 and the assembly slide 7 are fixedly connected by the limiting teeth 12 and the limiting slot 24. The filter placement groove 23 is used to hide the dust filter 13. The dust filter 13 is used to block and filter external dust. The filter shaping frame 3 is used to support the installation of the dust filter 13. The disassembly pinch 4 makes it easy to disassemble and assemble the filter shaping frame 3 by hand.
