This utility model discloses a modular probe assembly test fixture, including a test fixture main frame and a chip limiting guide frame. The upper inner surface of the test fixture main frame has a guide frame groove, and the chip limiting guide frame is installed within the guide frame groove. The lower inner surface of the test fixture main frame has a needle plate groove, and a frame-shaped probe plate is installed within the needle plate groove. The inner sidewall of the probe plate has a first snap-fit ​​structure. Multiple probe assembly modules are installed within the probe plate, and each probe assembly module has a second snap-fit ​​structure around its perimeter. The multiple probe assembly modules are arranged in a matrix. The probe assembly modules around the perimeter of the matrix arrangement are snapped and fixed by the first snap-fit ​​structure and the second snap-fit ​​structure. Each pair of adjacent probe assembly modules is snapped together by the second snap-fit ​​structure. The probe plate is assembled from at least two needle plate main bodies. This utility model's modular probe design reduces the difficulty of probe installation and replacement.

The utility model has the advantages that the combination modes are diversified and the interestingness is strong due to the magnetic attraction design; modularized magnetic sheet installation allows independent replacement of damaged magnetic sheets, overall disassembly is not needed, and maintenance is convenient.

This invention relates to the field of vacuum electronics technology, specifically to a wide-range adjustable magnetic positioning device for a superconducting magnet used in a gyroscopic traveling wave tube. The device includes a superconducting magnet and two coaxially arranged left and right compensation coils connected to the left and right end faces of the superconducting magnet. A temperature-controlled hole is formed through the middle of the superconducting magnet, into which the gyroscopic traveling wave tube is inserted. Both ends of the superconducting magnet have a first groove and a second groove for positioning and securing the left and right compensation coils. This invention increases the movable axial distance between the compensation coils and the superconducting magnet while maintaining a constant compensation coil current, thereby effectively improving the range and accuracy of the magnetic positioning device, allowing the gyroscopic traveling wave tube to operate at its optimal performance. It features convenient use, simple operation, high sensitivity, high accuracy, a wide range of magnetic positioning variations, and rich combinations of magnetic positioning methods.

The utility model relates to the technical field of silencers, and discloses a silencer assembly which comprises a cylinder body, stamping end covers are fixed at two ends of the cylinder body, pressing grooves are arranged on outer side surfaces of the stamping end covers in an array mode, connecting sleeves are fixed on the stamping end covers, silencing hole pipes are fixed in the connecting sleeves, red copper transition terminals are fixed at one ends of the silencing hole pipes, and the red copper transition terminals are fixed at the other ends of the silencing hole pipes. Silencing holes are formed in the silencing hole pipe in an array mode, and the stamping end cover is connected with the cylinder body in a welded mode.
