As shown in fig. 1 to 3, a testing fixture 100 (for example, a focusing fixture for NBC model testing) according to a first preferred embodiment of the present invention mainly includes a base 10, at least one circuit board, a pressing cover 30, a micro switch 40, and the like. The base 10 may have a testing plane 11, and the testing plane 11 may have a first slot 12 for placing a testing product 13. The at least one circuit Board includes a first circuit Board 21 (e.g., AB Board) capable of being electrically connected to the test product 13 and a second circuit Board 22 (e.g., JXO7) electrically connected to the first circuit Board 21. The cover 30 is rotatably mounted to the base 10 and can be flipped between an open position (shown in fig. 2) and a closed position (shown in fig. 3). The microswitch 40 is positioned in correspondence with the gland 30 and has a power-on and a power-off position. As shown in fig. 3, when the pressing cover 30 is turned over to the fastening position, it contacts the micro switch 40, and the micro switch 40 is located at the power-on position, so as to power on the test product. As shown in fig. 2, the gland 20, when flipped to the open position, is out of contact with the microswitch 40 and places the microswitch 40 in the de-energized position to de-energize the test product 13.

In this embodiment, as shown in fig. 1, the gland 30 covers at least a portion of the test product 13. Preferably, a limit mounting groove is further disposed on the base 10, for example, the limit mounting groove includes a first limit mounting groove 14 disposed corresponding to the first circuit board 21 and a second limit mounting groove 15 disposed corresponding to the second circuit board 22, and is configured to correspondingly accommodate the first circuit board 21 and the second circuit board 22, respectively. Furthermore, a fixing plate 122 may be correspondingly disposed above the second circuit board 22 for fixing the second circuit board 22 after being mounted.

As shown in fig. 4 to 5, a testing fixture 200 (for example, a two-in-one fixture for NBC model testing) according to a second preferred embodiment of the present invention is shown, which also includes a base 10, at least one circuit board, a pressing cover 30, a micro switch 40, and the like. The base 10 may have a testing plane 11, and the testing plane 11 is provided with a first slot 12 for placing a testing product 13. The at least one circuit Board includes a first circuit Board 21 (e.g., AB Board) capable of being electrically connected to the test product 13 and a second circuit Board 22 (e.g., JXO7) electrically connected to the first circuit Board 21. The cover 30 is rotatably mounted on the base 10 and can be turned between an open position and a closed position. The microswitch 40 is positioned in correspondence with the gland 30 and has a power-on and a power-off position. When the pressing cover 30 is turned over to the buckling position, the pressing cover contacts with the micro switch 40, and the micro switch 40 is located at the power-on position, so that the test product is powered on. The gland 20, when inverted to the open position, is out of contact with the microswitch 40 and places the microswitch 40 in the de-energized position to de-energize the test product 13.

In this embodiment, particularly, the test fixture 200 further includes at least one fixing structure, for example, a first fixing structure 50 disposed corresponding to the first circuit board 21. Preferably, the first fixing structure 50 may be, for example, a fixing block having a fixing groove, and is disposed adjacent to an end of the first circuit board 21 electrically connected to the test product 13, so as to fix the first circuit board 21 after the first circuit board 21 is electrically connected to the test product 13, and make it flush with the first groove 12, thereby preventing the first fixing structure 50 and the first groove 12 from having a height difference to cause the first circuit board 21 to tilt after being connected to the test product 13, which may cause damage to a product module.

In the present embodiment, as shown in fig. 4, the pressing cover 30 can preferably cover at least a part of the test product 13 and a part of the first fixing structure 50.

In the present invention, the two embodiments are both exemplified by two circuit boards, but it is understood that in other embodiments, only one circuit board may be provided, or more circuit boards may be provided, which are not intended to limit the present invention. In the present invention, the pressing cover 30 may further be provided with an MIC acoustic reception hole and an ALS small plate.

In other embodiments, the first groove 12 may be disposed on a mounting seat (not shown) that is detachably mounted on the base 10. By making the first groove 12 detachable, jig management can be facilitated and cost can be reduced.

Use the utility model discloses a

test fixture

100, 200 can test the NBC model, and its concrete mode of operation is as follows:
