Description

Technical Field

[0001] This utility model belongs to the field of pyrotechnic performance testing technology, and relates to a testing device for static performance testing of pyrotechnics. Background Technology

[0002] After assembly, pyrotechnic products usually need to undergo static performance inspection and testing. This is generally done by connecting the test socket to the test fixtures and instruments. Moreover, it is often necessary to test multiple resistance values, which requires manual operation, resulting in low efficiency and inconvenience.

[0003] The existing technical solution uses a tooling test box. The box body 1 has a connector 3, and the panel 2 has multiple terminals 4. When using it for testing, first connect the test cable to the connector of the tooling test box, then use a milliohm meter and an analog multimeter to connect to the terminals corresponding to the contacts to be tested, and record the data. For example... Figure 1 As shown.

[0004] Currently, when manually using a milliohm meter or pointer multimeter probes inserted into the terminals, after each data point is tested, the probe 5 must be moved to the next set of terminals until all data points are tested.

[0005] This method typically requires two people: one to operate the testing equipment and the other to record the data. Utility Model Content

[0038] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0039] Reference Figures 2 to 6As shown, the testing device for static performance testing of pyrotechnic products in this embodiment includes a housing 1, a panel 2, a connector 3, terminals 4, and band switches 7. The panel 2 is installed on the top of the housing 1, the connector 3 is installed on the side wall, and the interior provides wiring space. Two terminals 4 and multiple band switches 7 are installed on the panel 2. The band switches 7 are 2-pole multi-position switches. The two common terminals of each band switch 7 are connected to two terminals 4 respectively. The two terminals 4 are used to connect a milliohm meter or an analog multimeter. The connector 3 is connected to the test cable of the pyrotechnic product under test and the terminals of the band switches 7.

[0040] The lower ends of the two terminals 4 are connected to the common terminal of the band switch 7, and the upper ends are equipped with banana plugs 6, through which the leads of a milliohm meter or pointer multimeter are connected.

[0041] Insert the banana plug 6 into the center hole at the top of the terminal 4 to ensure a reliable connection during testing.

[0042] Depending on the actual testing requirements, the leads of connector 3 can be soldered to different pins of band switch 7. For example... Figure 3 As shown, the band switch 7 uses a 2-pole 11-position design (or a 2-pole N-position design, the number of positions N being selected according to actual needs), enabling switching to different paths and measuring the electrical performance between different contacts of the connector 3, including measuring the resistance and insulation resistance of different paths. The band switch 7 includes a body, a knob 9, long leads 10, and short leads 11. The body is mounted on the panel 2, the knob 9 is mounted on the top of the body, and the long leads 10 and short leads 11 are spaced apart at the bottom of the body.

[0043] like Figure 4 As shown, the band switch has two common terminals, C1 and C2. These terminals are connected to the banana plug 6 of a milliohm meter or an analog multimeter. When the band switch is switched to different ranges, the circuit connected at that range can be tested. For example, when the band switch 7 is in range 1, the electrical performance between points 1 and 12 is tested; similarly, when the band switch 7 is switched to range 11, the electrical performance between points 11 and 22 is tested.

[0044] Preferably, the positions of the band switch knob 9 on the panel 2 are marked with laser markings, so that during actual testing, it is immediately clear which two contacts are being measured at each position. Figure 2 The number 8 in the diagram represents the gear position indicator.

[0045] Preferably, the band switches 7 are arranged from left to right and from top to bottom, with the positions rotated clockwise. Testing and recording are also performed in this order. Specifically, during actual testing, the band switch in the upper left corner is operated first, switching positions clockwise one by one, recording data after each position switch. After all positions have been switched, the band switch is returned to its initial position. Then, the other band switches are operated sequentially from left to right and from top to bottom.

[0046] Preferably, the test contacts of the milliohm meter and the pointer multimeter can be partitioned. For example, the test contacts of the milliohm meter can be set to the three band switches in the first row, and the test contacts of the pointer multimeter can be set to the three band switches in the second row. That is, the three band switches in the first row are used for the test items of the milliohm meter, and the three band switches in the second row are used for the test items of the pointer multimeter.

[0047] The number of band switches and the number of ranges for each band switch can be selected according to actual working needs.

[0048] As can be seen from the above technical solution, this utility model has the following significant features:

[0049] 1. Static performance testing of pyrotechnic products is performed using a band switch. The banana plug of the test instrument is connected to the corresponding two terminals. The test can be performed by switching the band switch positions.

[0050] 2. Using banana plugs instead of test probes allows for a tight fit with the terminals, freeing up the operator's hands.

[0051] 3. The test contacts of milliohm meters and analog multimeters can be partitioned, which is more in line with ergonomics.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
