Description

Technical Field

[0001] The utility model relates to the technical field of electronic product vibration testing, in particular to a triaxial vibration testing tool for embedded modules. Background Art

[0002] During the development and production process of electronic products, reliability identification and acceptance tests, vibration tests, and environmental stress screening tests for electronic products are generally required. These tests all include vibration stress, and the vibration stress needs to be applied to the three axes of the electronic product.

[0003] Due to technical limitations, the vibration table of existing embedded modules has a single vibration direction and can only vibrate in the horizontal (xy) or vertical (z) direction. Figure 1 As shown. If the direction of the vibration stress loaded on the embedded module is to be changed, the only way is to switch the vibration table (xy→z or xy←z) and re-clamp the test fixture, or keep the vibration table unchanged and change the clamping direction of the test fixture. Both methods require multiple disassembly and assembly of the test fixture, which on the one hand leads to cumbersome operation, long time consumption, and high physical labor intensity of the test personnel, and on the other hand, it is easy to cause inconsistency between the states of the test fixture before and after, introduce unknown risks, and have an adverse effect on the test results. Utility Model Content

[0007] Compared with the prior art, the triaxial vibration test fixture for embedded modules provided by the utility model has the following beneficial effects:

[0008] The tooling frame of the utility model provides an installation foundation for mutually perpendicular x-axis mounting rails, y-axis mounting rails, and z-axis mounting rails. The mounting rails provide guidance and positioning for the installation of the adapter plate, and the embedded module to be tested is installed in the test tooling through the adapter plate.

The adapter board is used to install the embedded module to be tested, and can be slidably installed on the x-axis, y-axis or z-axis mounting rails. There are one or more adapter boards, and the tool core board 2 is fixedly installed in the tool frame 3. Three groups of CPCI sockets are provided on the tool core board 2, which are respectively connected to the adapter boards on the x-axis, y-axis, and z-axis mounting rails, and the tool core board is electrically connected to the outside through an external electrical connector.

[0024] When implementing:

[0025] like Figure 2-Figure 3 As shown, the left panel 1 is located on the leftmost side of the test fixture and is the left end cover of the fixture, and is installed to the fixture frame 3 through a threaded connection.

[0026] like Figure 4 As shown, the tooling core board 2 is the core processing unit of the test tooling, and is installed on the left side of the tooling frame 3 through a threaded connection. The tooling core board 2 is provided with a JL27 socket and a JL24 socket, and the above connectors are connected to the external electrical connector of the front panel 7 on the tooling frame 3 with their corresponding model plugs and wires. The working core board 2 also provides 3 groups of CPCI sockets connected to the adapter board, and each group of CPCI sockets can be set with one or more. Figure 2-Figure 6 In the illustrated embodiment, three groups of CPCI sockets connected to the adapter board are provided with one CPCI socket in each group, which are respectively connected to the first adapter board 4, the second adapter board 5 and the third adapter board 6. The tooling core board 2 can simulate the host device environment and monitor the performance of the module to be tested. The external electrical connector can supply power to the test tooling, manage the module to be tested, communicate with the host computer, etc., so that the test tooling can simulate the environment of the embedded module host device and can regularly monitor the performance of the module to be tested during the vibration test.

[0027] like Figure 5As shown, the tooling frame 3 is composed of a front panel 7, a bottom plate 8, a partition 9, a rear panel 10 and an upper cover plate 11. It is connected by threads to form a whole, and its main functions are: fixing the tooling core board 2; fixing the external electrical connector, the external connector includes 1 YW120Fm01S1-F connector and 2 YL11B10NB1007JR connectors, the YW120Fm01S1-F connector is connected to the JL24 socket of the tooling core board 2, which is used for the tooling core board 2 to communicate with the host computer, and 1 YL11B10NB1007JR connector is connected to the JL27 socket of the tooling core board 2, which is used to test the power supply of the tooling; 1 YL11B10NB1007JR connector is connected to another JL24 socket of the tooling core board 2, which is used to manage the module to be tested. The tooling frame 3 provides three sets of mutually perpendicular x-axis mounting rails, y-axis mounting rails, and z-axis mounting rails. In a specific embodiment, the rails can be set as an integrated structure with the front panel 7, bottom plate 8, partition plate 9, and rear panel 10 on the tooling frame 3.

[0028] like Figure 6 As shown, the first adapter plate 4, the second adapter plate 5 and the third adapter plate 6 are composed of an adapter plate main board 13, a wedge-shaped locking mechanism 12, an adapter plate reinforcement plate 15 and a puller 14, which are adapters for installing the module to be tested to the tooling, and provide electrical and mechanical interfaces for the module to be tested. In this embodiment, the adapter plates are set to three pieces, which is not used to limit the utility model. Those skilled in the art can know from the content disclosed in the utility model that the adapter plates can be set to a corresponding number according to the needs of the vibration test, and the CPCI socket of the tooling core board 2 needs to be supported.

[0029] The wedge-shaped locking mechanism 12 is a commonly used component for fast plug-in and pull-out locking of boards and cards. The wedge-shaped locking mechanism 12 used in this embodiment is a 5-section slider type, and the matching surfaces between the sliders are inclined surfaces. When the end screws are tightened, the overall length is compressed. Limited by the bottom rail, the first, third, and fifth sections are close to the bottom surface, while the second and fourth sections are raised, thereby increasing the overall height and fixing the entire adapter board in the slot. The puller 14 is also a commonly used component for fast plug-in and pull-out locking of boards and cards. By using the small notch at the end of the slot, the puller 14 can be operated through the lever principle to safely and quickly complete the plug-in and pull-out of the adapter board.

[0030] After the module to be tested is fixed to the adapter board as required by the host device, insert the adapter board into the mounting rail of the test fixture, press the puller 14 to fully insert the adapter board plug into the corresponding socket of the test fixture core board 2, and fix the adapter board to the fixture frame 3 by tightening the screws of the wedge-shaped locking mechanism 12. There can be 1 to 3 adapter boards, which are switched between the above-mentioned rails. After the x, y, and z axes are switched, the three-axial requirements of the vibration test of the module to be tested are met. When switching, each adapter board only needs to turn two screws for quick disassembly and assembly. The number of modules that the adapter board allows to be tested simultaneously can be multiple ( Figure 68 are shown).

[0031] The test fixture is fixed to the vibration table by a pressure plate, a long screw and a nut. After being fixed, it does not need to be repeatedly disassembled and assembled during the entire vibration test cycle.

[0032] The tooling frame of the utility model provides an installation foundation for mutually perpendicular x-axis mounting rails, y-axis mounting rails, and z-axis mounting rails. The mounting rails provide guidance and positioning for the installation of the adapter plate, and the embedded module to be tested is installed in the test tooling through the adapter plate. When the test tooling of the utility model is used for vibration testing, there is no need to replace the vibration table, and there is no need to disassemble and assemble the test tooling as a whole many times. The module to be tested can quickly adjust the axial direction in the test tooling through the adapter plate, saving disassembly and assembly time, reducing the physical labor of the test personnel, creating a safe and reliable test environment, and obtaining accurate test results.
