Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic measurement and testing and data acquisition technology, and in particular to a pin-type data acquisition signal triggering device. Background Technology
[0002] High and low level signal triggering mainly refers to the requirement that certain data acquisition systems need to be started by inputting two step signal commands: a high-level signal (rising edge) and a low-level signal (falling edge). In existing technologies, commonly used triggering devices include toggle switches, push-button switches, and limit switches. However, these triggering methods have the following drawbacks: 1. They are prone to misoperation or failure to trigger; 2. The command signal is singular, only generating a high or low level; 3. Manual start-up is required, and the installation orientation is relatively strict; 4. Daily maintenance and repair are complex. Therefore, existing technologies cannot meet the technical requirements of certain specific test conditions, such as airdrop tests, long-stroke impact tests, and synchronous triggering of multiple data acquisition systems. Utility Model Content
[0003] The purpose of this utility model is to provide a pin-type signal triggering device for a data acquisition system. After being connected to the corresponding data acquisition system, the rising edge and falling edge signals are generated by pulling out and inserting soft pins, thereby triggering the start of the data acquisition system.
[0004] The technical solution adopted by this utility model is as follows: A pin-type data acquisition signal triggering device includes a housing, a self-reset switch and a soft pin. The housing is provided with an L-shaped cavity. A steel ball, a self-reset switch, a locking screw, a wire clamp and a pressure plate are arranged sequentially at one end of the L-shaped cavity. The soft pin is inserted into the other end. After the soft pin is fully inserted, it generates a trigger signal by squeezing the steel ball to compress the self-reset switch and complete the first triggering operation. After the soft pin is completely pulled out, the steel ball (6) and the self-reset switch reset at the same time to complete the second triggering action.
[0005] In the above scheme, the self-reset switch is a KAN-A8-3 type switch.
[0006] In the above scheme, the triggering device also includes a fixing nut, which is used to fix the soft pin.
[0007] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: by using a soft pin, its flexibility allows for insertion and removal at any angle, improving the reliability of the signal trigger. It effectively solves the following technical problems: the high difficulty and danger of triggering the data acquisition system during airdrop tests; the problem of synchronous triggering between multiple data acquisition systems; and the safety of personnel during long-stroke impact tests.
[0008] After connecting to the corresponding data acquisition unit, both rising and falling edge step signals can be generated by inserting or removing the soft connector. This allows for flexible wiring combining two trigger actions. In other words, inserting or removing the soft connector generates both rising and falling edge step signals. This flexibility allows for different combinations depending on the application scenario, greatly improving its applicability. Attached Figure Description

[0012] 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 only used to explain this utility model and are not intended to limit this utility model.
[0013] Reference Figure 1 , 2 The invention will now be described in detail through three specific use cases.
[0014] A pin-type data acquisition signal triggering device includes a housing 1, a KAN-A8-3 type self-resetting switch 5, and a soft pin 8. The housing 1 includes a locking screw sleeve 2, a wire clamp 3, a pressure plate 4, a steel ball 6, and a fixing nut 7. This invention designs two mechanical triggering actions: insertion of the soft pin 8 triggers the action, and removal of the soft pin 8 triggers it again. First, after the soft pin 8 is fully inserted, the steel ball 6 is squeezed to compress the self-resetting switch 5, generating a trigger signal and completing one triggering action. Second, after the soft pin 8 is fully removed, the steel ball 6 and the self-resetting switch 5 simultaneously reset, completing a second triggering action. This can meet the triggering requirements of different data acquisition systems.
[0015] This utility model is compact in size and weight, flexible in installation, and highly versatile. It adopts a mechanical action design, which makes it easy to operate, highly reliable, and simple to maintain, greatly reducing the operational complexity of triggering data acquisition systems in various electronic measurement experiments.
[0016] The implementation principle of this utility model embodiment is as follows:
[0017] (1) Airdrop test.
[0018] In the airdrop test, the trigger wire of the data acquisition system was connected to the signal triggering device of the pin-type data acquisition unit. The trigger was fixed to the surface of the airdropped item using a fixing nut and mounting hole. A weak core wire was used to restrain the tail of the soft pin on the fixing nut using the groove of the fixing nut, preventing the soft pin from being accidentally pulled out during handling and causing false triggering. One end of the soft pin pull-out rope was tied to the soft pin loop, and the other end was tied to a fixed point inside the aircraft cabin. During the airdrop, the inertia of the airdropped item was used to pull out the soft pin, triggering the data acquisition system.
[0019] (2) Synchronous triggering of different data acquisition systems in a single test.
[0020] In tests involving two or more data acquisition systems, rising edge triggering and falling edge triggering may occur simultaneously. Depending on the trigger signal required by each data acquisition system, the rising edge and falling edge terminals of the plug-in data acquisition unit's signal triggering device are connected respectively. This way, during testing, only the soft connector needs to be unplugged to achieve synchronous triggering of multiple data acquisition systems, which is convenient and efficient.
[0021] (3) Long-stroke impact test
[0022] For impact tests with long strokes, data acquisition systems are often mounted on the test specimen. Referring to the method in Case 1, the pin-type data acquisition device is fixed to the surface of the test specimen. During the test, a long release rope on the ground can be used for remote triggering, greatly ensuring the safety of the test personnel.
[0023] Main performance of pin-type data acquisition unit signal triggering device
[0024] Ambient temperature －55℃~85℃ relative humidity 93±3％(40℃) Rated load 32V DC, 1A Contact resistance ≤0.015Ω Insulation resistance ≥1000MΩ Action stress 20N Button lifespan 10,000 times
[0025] The above technical solutions are merely preferred embodiments of this utility model and should not be construed as limiting the scope of this utility model. Therefore, any equivalent changes made in accordance with the scope of this utility model patent shall still fall within the protection scope of this utility model.
