Therefore, after the gas-filled trigger tube is assembled, a vibration test of the entire tube is usually carried out to evaluate whether its vibration resistance in the expected environment meets the technical requirements.

[0003] The inflatable trigger tube is usually provided with at least an anode, a cathode and a trigger electrode. The whole tube vibration test process includes: when the anode, cathode and trigger electrode of the inflatable trigger tube are energized and a certain voltage and acceleration are maintained, the vibration stress along the OX direction and the OY direction for a duration of 5 minutes is applied to the trigger tube through the vibration table. After the test, the appearance of the inflatable trigger tube should be free of mechanical damage, and all performance indicators should be qualified.

[0066] The first end of the cathode conductive stud 21 is connected to the trigger electrode insulating seat 15 through a connecting screw 18. The trigger electrode insulating seat 15 is provided with a lower trigger groove. The cathode conductive stud 21 is provided with a conductive cavity communicating with the lower trigger groove.

[0067] A trigger pole insulating sleeve 20 is embedded between the conductive cavity and the lower trigger groove, the second end of the trigger pole screw 17 is in the trigger pole insulating sleeve 20, and the trigger pole wire passes through the conductive cavity and is connected to the second end of the trigger pole screw 17;

[0068] The cathode disk spring 19 is sleeved on the trigger pole insulating seat 15, and the first end of the cathode disk spring 19 is used to abut the cathode disk of the inflatable trigger tube, and the second end of the cathode disk spring 19 is connected to the annular groove of the first end of the cathode conductive stud 21, and the second end of the cathode conductive stud 21 is connected to the cathode wire.

[0069] In this embodiment, a cavity is provided inside the shell 8, and the cavity can be used to place the inflatable trigger tube and other structures for fixing the inflatable trigger tube. In order to meet the requirement that the inflatable trigger tube needs to apply vibration stress in the OX direction and the OY direction during the whole tube vibration test, through holes are also provided in the shell 8 along the horizontal and vertical directions of the cavity. When the vibration stress direction needs to be changed during the test, the contact surface between the shell 8 and the vibration table of the inflatable trigger tube is replaced accordingly, and then the shell 8 is fixed to the vibration table by bolts or other means through the through holes.

[0070] In the cavity, the anode terminal fixing mechanism is locked and abutted with the side of the gas-filled trigger tube close to the anode. The second end of the anode conductive stud 11 passes through the anode terminal fixing mechanism and abuts against the anode disk of the gas-filled trigger tube. On the one hand, the anode terminal fixing mechanism can limit the anode conductive stud 11. At the same time, the anode conductive stud 11 is electrically powered by connecting the anode wire to the first end of the anode conductive stud 11 outside. In addition, the second end of the anode conductive stud 11 is also provided with an anode groove facing the anode of the gas-filled trigger tube, which can be used to accommodate the anode protruding from the anode disk.

When the trigger pole wire passes through the conductive cavity and is connected to the second end of the trigger pole screw 17, the trigger pole can be energized along the trigger pole spring 16. At the same time, based on the insulating characteristics of the trigger pole insulating sleeve 20, the trigger pole screw 17 can be prevented from contacting the cathode conductive stud 21 when connected to the trigger pole wire, thereby ensuring the insulation between the trigger pole and the cathode of the inflatable trigger tube;

[0072] In the cavity, an annular groove is provided at the first end of the pole conductive stud 19, and a cathode disk spring 19 is provided on the trigger pole insulating seat 15. The cathode disk spring 19 is provided between the cathode disk of the gas-filled trigger tube and the annular groove. The setting of the annular groove can play a certain limiting role on the cathode disk spring 19. When the second end of the cathode conductive stud 21 is connected to the cathode wire, the cathode can be energized along the cathode disk spring 19. At the same time, based on the elastic characteristics of the cathode disk spring 19, the deviation in the size specification of the gas-filled trigger tube can be adapted to achieve effective connection.

[0073] Based on the above scheme, after the inflatable trigger tube is installed in the cavity of the shell 8, through the cooperation of the anode terminal fixing mechanism, the anode conductive stud 11, the trigger pole insulating seat 15, the trigger pole spring 16, the trigger pole screw 17, the cathode disk spring 19, the cathode conductive stud 21, the trigger pole wire and the cathode wire, it can meet the test power-on requirements while effectively preventing the inflatable trigger tube from being displaced during the test. In addition, combined with the through holes arranged in both directions, it is convenient to adapt to the requirements of the application direction of the vibration stress and then firmly connected with the vibration table, thereby improving the test accuracy of the whole tube vibration test of the inflatable trigger tube. In addition, the fixing device structure is easy to load and unload, replace and can be used repeatedly, and has a certain versatility for similar inflatable trigger tube vibration tests.

[0074] During the specific assembly implementation, the trigger pole spring 16 and the trigger pole screw 17 can be fixed together first, and the trigger pole screw 17 can be tightened in the trigger pole insulating seat 15. The trigger pole insulating seat 15, the trigger pole insulating sleeve 20 and the cathode conductive stud 21 are connected and placed in the lower end of the cavity, and the cathode conductive stud 21 has been welded with the cathode wire, and the trigger pole screw 17 has been welded with the trigger pole wire. The inflatable trigger tube is placed in the cavity, and the anode conductive stud 11 is assembled with the anode end fixing mechanism and then placed in the upper end of the cavity and connected with the inflatable trigger tube. The inflatable trigger tube is fastened in the cavity by adjusting the anode end fixing mechanism, and the anode wire is connected from the anode conductive stud 11, and then fixed to the vibration table with bolts through the φ10 through hole, and then the vibration test in the OY direction can be carried out. After the shell is flipped 90° accordingly, the power is continued to be turned on for the vibration test, and the vibration test in the OX direction can be completed.

[0075] In a specific implementation of this embodiment, refer to Figure 3 ; The anode terminal fixing mechanism includes a threaded end cap 9 and an end cap nut 10;

[0076] The first end of the threaded end cap 9 is sleeved with an end cap nut 10, and the second end of the threaded end cap 9 abuts against the shell of the inflation trigger tube close to the anode side;

[0077] A first end cap groove is formed at the first end of the threaded end cap 9, and a first end of the anode conductive stud 11 is located in the first end cap groove and is sleeved with an anode nut 12;

[0078] A second end cap groove is formed at the second end of the threaded end cap 9, and the second end of the anode conductive stud 11 is located in the second end cap groove;

[0079] An anode spring 13 is sleeved on the anode conductive stud 11 , and the anode spring 13 abuts between the second end cover groove and the second end of the anode conductive stud 11 .

[0080] In a more specific embodiment, see Figure 3The anode conductive stud 11 is sleeved with an anode spring insulating sleeve 14, and the anode spring insulating sleeve 14 includes a small end cylinder and a large end cylinder connected in sequence;

[0081] The anode spring 13 is sleeved on the small end cylinder, and the anode spring 13 abuts between the second end cover groove and the first end of the large end cylinder;

[0082] The second end of the large-end cylinder abuts against the second end of the anode conductive stud 11 .

[0083] In this embodiment, a first end cap groove facing the outside is formed at the first end of the threaded end cap 9, a second end cap groove facing the cavity is formed at the second end cap 9, a first end of the anode conductive stud 11 is located in the first end cap groove, and a second end of the anode conductive stud 11 is passed through the first end cap groove to the second end cap groove and abuts against the anode disk of the gas-filled trigger tube;

[0084] An end cap nut 10 is provided on the outer sleeve of the first end of the threaded end cap 9. After the second end of the threaded end cap 9 is screwed into the inner thread at the upper end of the cavity until it abuts against the shell of the inflation trigger tube close to the anode side, the anode spring 13 sleeved on the anode conductive stud 11 is also stressed and compressed between the second end cap groove and the second end of the anode conductive stud 11. The thread of the end cap nut 10 is opposite to the thread direction of the inner thread at the upper end of the cavity. An anode nut 12 is provided on the outer sleeve of the first end of the anode conductive stud 11. By adjusting the end cap nut 10 and the anode nut 12 and locking them at the same time, the inflation trigger tube can be prevented from moving up and down in the cavity consistent with the outer diameter of the inflation trigger tube during vibration, ensuring that the anode conductive stud 11 can be in close contact with the anode disk;

[0085] In a preferred embodiment of the present structure, an anode spring insulating sleeve 14 is sleeved on the anode conductive stud 11, and the anode spring insulating sleeve 14 includes a small end cylinder and a large end cylinder connected in sequence, and the anode spring 13 is inserted into the small end cylinder and abuts between the second end cover groove and the large end cylinder. By adding the anode spring insulating sleeve 14, the force transmitted to the end face of the anode conductive stud 11 when the anode spring 13 is compressed can be made more uniform.

[0086] In a specific implementation of this embodiment, refer to Figure 3 The second end of the cathode conductive stud 21 is sleeved with a cathode welding ring 22 connected to the cathode wire.

[0087] In a more specific embodiment, see Figure 3 The second end of the cathode conductive stud 21 is sleeved with a cathode nut 23 that abuts against the cathode welding ring 22 .

[0088] In this embodiment, the second end of the cathode conductive stud 21 is provided with a cathode welding ring 22 for connecting to the cathode wire. The cathode welding ring 22 provides a more stable contact surface to form a more uniform and reliable electrical connection. At the same time, the cathode nut 23 can assist in fastening the cathode welding ring 22 to the cathode conductive stud 21 to prevent the cathode welding ring 22 from loosening due to vibration.

[0089] In a specific implementation of this embodiment, refer to Figure 3 The shell 8 is provided with a cathode wiring hole 24 , and the cathode wire passes through the cathode wiring hole 24 and is connected to the second end of the cathode conductive stud 21 .

[0090] In a specific implementation of this embodiment, refer to Figure 3 The shell 8 is provided with a trigger pole wiring hole 25 , and the trigger pole wire passes through the conductive cavity along the trigger pole wiring hole 25 .

[0091] In this embodiment, a cathode wiring hole 24 and a trigger pole wiring hole 25 are provided at one end of the shell 8 near the trigger pole. The cathode wires and the trigger pole wires are limited by the setting of the wiring holes, which helps to ensure the orderly layout of the wires and prevent the wires from moving excessively during use, thereby reducing the risk of electrical short circuits caused by wire confusion.

[0092] In a specific implementation of this embodiment, refer to Figures 4 to 5 , there are multiple cavities.

[0093] In this embodiment, more than two cavities, for example, four cavities, are provided in the shell 8. The multi-cavity design allows whole-tube vibration tests of multiple inflatable trigger tubes to be performed simultaneously in the shell 8, thereby improving the test efficiency.

[0094] In a specific implementation of this embodiment, refer to Figures 4 to 6 The shell 8 is provided with multiple through holes in the horizontal and vertical directions of the cavity and they are evenly distributed.

[0095] In this embodiment, since the shell 8 needs to be fixedly connected to the vibration table along the horizontal and vertical directions of the cavity, the connection stability can be increased by designing the shell with multiple through holes. At the same time, the uniform distribution of through holes can reduce the structural instability caused by uneven connection points, thereby improving the reliability of the connection.

[0096] In a specific implementation of this embodiment, refer to Figure 4 The shell 8 is in the shape of a rectangular parallelepiped, which can provide a relatively sufficient internal space, and at the same time, a larger shell bottom area facilitates providing better stability.

[0097] See also Figure 7The second embodiment of the present invention provides an inflatable trigger tube, comprising: a tube body 1, an anode disk 2, an anode 3, a cathode 4, a cathode disk 5, a trigger electrode 6 and a trigger disk 7;

[0112] In the mold cavity, the anode disk conductive block 26 is located in the anode slot of the anode conductive stud 11, and is used to connect the second end of the anode conductive stud 11 and the anode disk of the gas-filled trigger tube, and to accommodate the anode protruding from the anode disk through the opened anode cavity, and the anode wire can be energized along the anode disk conductive block 26 through the anode conductive stud 11; in the mold cavity, the first end of the trigger pole spring 16 and the cathode disk spring 19 are connected to the trigger pole conductive block 29, and the trigger pole conductive block 29 is connected to the trigger pole of the gas-filled trigger tube and the cathode disk conductive block 28, and the cathode disk conductive block 28 is connected to the trigger pole of the gas-filled trigger tube. 8 A space is formed by setting a partition groove to avoid the trigger disk. After the trigger disk is inserted into the gas-filled trigger tube into the central hole through the slit opened along the partition groove, it is rotated at a certain angle until the cathode disk conductive block 28 abuts against the lower end surface of the cathode disk of the gas-filled trigger tube, thereby enabling the trigger pole and the cathode to be energized. In addition, a tube seat cavity is opened in the insulating tube seat 27 in the cavity to install the gas-filled trigger tube. The protrusion arranged inside the tube seat cavity abuts against the upper end surface of the cathode disk of the gas-filled trigger tube, and is screwed with the anode disk conductive block 26 and the trigger pole conductive block 29 respectively to form a stable overall structure.

[0113] During the specific assembly implementation, the inflatable trigger tube can be placed on the trigger pole conductive block 29 first, and then the trigger disk can be placed along the slit of the cathode disk conductive block 28 and rotated for a certain angle, and then screwed into the second end of the tube seat cavity and tightened. The anode disk conductive block 26 is screwed in from the first end of the insulating tube seat 27 against the surface of the anode disk to form an integral component; after the trigger pole insulating seat 15, the trigger pole insulating sleeve 20 and the cathode conductive stud 21 are connected and placed at the lower end of the cavity, the entire component is placed in the cavity, and then the anode conductive stud 11 and the anode end fixing mechanism are placed and connected, and finally fixed on the vibration table through the through hole, and the vibration test can be carried out.

[0114] In some embodiments, the shell 8, the threaded end cap 9 and the end cap nut 10 are made of aviation plexiglass, which has good insulation properties, mechanical strength, impact resistance and high temperature resistance, and can be used in environments with large dynamic loads and severe wear in the external environment.

The polytetrafluoroethylene material has excellent corrosion resistance, insulation and extremely high melting point, and maintains good performance in high temperature, low temperature and humid environments, and can maintain stable performance in such high-frequency and strong vibrations.
