Furthermore, it is required that the present invention is understood, not simply by the actual terms used but by the meaning of each term lying within.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic view of a first fixture provided in an embodiment of the present application; fig. 2 is a top view of the jig shown in fig. 1. Referring to fig. 1 and 2, in an embodiment of the present application, the fixture 100 may be provided with a receiving area 110a adapted to cover the product to be tested 200 and expose a portion of the surface of the product to be tested 200, and the fixture 100 may further be provided with a pressure fluid channel 110b, where a fluid outlet of the pressure fluid channel 110b may be used for being abutted with a cavity on the product to be tested 200 covered in the receiving area 110 a.

In this way, in the embodiment of the present application, the product 200 to be tested can be wrapped in the accommodating area 110a, and the pressure fluid can be introduced into the cavity of the product 200 to be tested through the pressure fluid channel 110 b. Therefore, the sealing performance of the product 200 to be tested can be judged by judging whether fluid flows out of the cavity of the product 200 to be tested. Therefore, compared with a mode of testing the sealing performance by using the water inlet test paper in the related technology, the shell does not need to be disassembled and assembled for many times, and the problem that the testing scheme in the related technology is inconvenient to implement can be solved.

It should be noted that, for example, in the embodiment of the present application, the pressure fluid channel 110b may be used for conveying pressure gas. Thus, pressurized gas may be introduced into the cavity of the product to be tested 200 through the pressure fluid channel 110 b. Further, for example, the sealing performance of the product 200 to be tested may be determined by putting the jig 100 provided with the product 200 to be tested in water, and observing whether bubbles are generated near the exposed surface of the product 200 to be tested. In addition, the sealing performance of the product 200 to be tested can be more accurately evaluated by counting the number of bubbles or the generation speed of the bubbles.

It should be noted that if the fluid conveyed into the cavity of the product to be tested 200 is a pressure gas, the sealing performance of the product to be tested 200 on which the components such as the circuit board are mounted can be tested. It can be understood that, when the cavity of the product 200 to be tested is filled with the pressure gas, if the jig 100 provided with the product 200 to be tested is put into water, the pressure in the cavity of the product 200 to be tested can be greater than the water pressure outside the cavity of the product 200 to be tested, so as to prevent the water from entering the cavity of the product 200 to be tested in the testing process, and further prevent the circuit board and other elements from being damaged. In addition, in the embodiment of the application, the part of the product 200 to be tested, which is easy to leak, can be determined by observing the generation part of the bubble, and the sealing performance of the part which is easy to leak can be improved in a targeted manner.

Further, in the embodiment of the present application, by adopting the test scheme of delivering the pressure gas into the cavity of the product 200 to be tested, the sealing performance of the assembled product 200 to be tested can be tested, so that the measured sealing performance parameter is closer to the real sealing performance of the product 200 to be tested.

It should be noted that in other embodiments of the present application, the pressure fluid channel 110b may be used to convey pressure fluid. Thus, a pressurized liquid may be introduced into the cavity of the product to be tested 200 via the pressurized fluid channel 110 b. Thus, the sealing performance of the product 200 to be tested can be judged by observing whether liquid seeps out from the vicinity of the exposed surface of the product 200 to be tested. It should be noted that if components such as the circuit board are mounted in the product 200 to be tested, a liquid that does not corrode the circuit board or conduct electricity may be selected. Those skilled in the art can select a suitable liquid to be delivered to the cavity of the product 200 to be tested according to actual requirements, and the description is not provided herein.

Fig. 3 is a schematic view of a second fixture according to an embodiment of the present disclosure; fig. 4 is a schematic view of the holding cavity in the jig shown in fig. 3 in an exposed state; fig. 5 is a schematic view of a third fixture provided in the embodiment of the present application; fig. 6 is a schematic view of the receiving cavity in the jig shown in fig. 5 in an exposed state. Referring to fig. 3 to 4, or fig. 5 to 6, on the basis of any one of the jigs provided in the embodiments of the present application, the jig 100 may include a first member 120, the first member 120 may be provided with an accommodating cavity 1201 adapted to accommodate the product 200 to be tested, the accommodating cavity 1201 may be provided in the accommodating area 110a, and the jig 100 may further include a second member 130 adapted to limit the product 200 to be tested in the accommodating cavity 1201.

Taking fig. 3 or fig. 5 as an example, in the embodiment of the present application, a surface of the second member 130 opposite to the accommodating cavity 1201 may form an accommodating area 110a together with the accommodating cavity 1201. In this way, in the embodiment of the present application, the product 200 to be tested may be disposed in the accommodating cavity 1201, and the product 200 to be tested may be limited in the accommodating cavity 1201 by the second member 130. Therefore, in the testing process, the product to be tested 200 can be limited, and the product to be tested 200 can be prevented from shifting to influence the accuracy of the testing result.

It should be noted that, in the embodiment of the present application, the second member 130 may be movably disposed on the first member 120, and the second member 130 may have a first state and a second state. When the second member 130 is in the first state, the second member 130 may abut against the product 200 to be tested disposed in the accommodating cavity 1201; when the second member 130 is in the second state, the second member 130 may be separated from the product 200 to be tested disposed in the accommodating chamber 1201. In this way, when the product to be tested 200 needs to be disposed in the jig 100, the second member 130 can be in the second state, and the accommodating cavity 1201 can be exposed, so that the product to be tested 200 can be placed in the accommodating cavity 1201; after placing the product 200 to be tested in place, can be so that the second member 130 is in the first state, can be so that the second member 130 with set up the product 200 to be tested in holding chamber 1201 butt, like this, can utilize the second member 130 to be spacing the product 200 to be tested in holding chamber 1201. In addition, when the product 200 to be tested needs to be taken out of the accommodating chamber 1201, the second member 130 may be brought into the second state. The solution for taking out the product 200 to be tested from the accommodating cavity 1201 is not described herein.

Referring to fig. 3 and 4, alternatively, in an embodiment of the present application, the second member 130 may be rotatably disposed on the first member 120, and the second member 130 may be rotatably switched between the first state and the second state.

For example, in the embodiment of the present application, the first member 120 may be provided with a rotating shaft, and the second member 130 may be rotatably connected to the first member 120 through the rotating shaft. In this way, when the product to be tested 200 needs to be disposed in the jig 100, the second member 130 can be rotated in a direction away from the accommodating cavity 1201, and the accommodating cavity 1201 can be exposed. When the product 200 to be tested arranged in the accommodating cavity 1201 needs to be limited in the accommodating cavity 1201, the second member 130 can be rotated towards the direction close to the accommodating cavity 1201 until the second member abuts against the product 200 to be tested.

It should be further noted that, referring to fig. 3 and fig. 4, on the basis of any one of the jigs including the first member and the second member provided in the embodiments of the present application, a through hole may be provided on a portion of the second member 130 opposite to the accommodating cavity 1201, so that a part of the surface of the product 200 to be tested accommodated in the accommodating cavity 1201 is exposed through the through hole. Further, for example, in other embodiments of the present application, the product 200 to be tested may be exposed on a part of the surface through a gap between the first member and the second member. In embodiments of the present application, there are many ways to expose a portion of the surface of the product 200 to be tested, not to mention.

Optionally, in an embodiment of the present application, the jig 100 may further include a locking device adapted to maintain the second member 130 in the first state. In order to facilitate those skilled in the art to better implement the solution provided by the embodiments of the present application, the following provides a reference for those skilled in the art to set up the locking device.

Fig. 7 is a schematic view of a fourth fixture provided in the embodiment of the present application, and fig. 8 is a schematic view of the fixture shown in fig. 7 with a locking device in an open state. Referring to fig. 7 and 8, the jig 100 may further include a first locking device 160 on the basis of the jig shown in fig. 4. That is, in the embodiment of the present application, the locking device may be the first locking device 160. When the second member 130 abuts against the product 200 to be tested accommodated in the accommodating cavity 1201, the first locking device 160 can be used to lock the second member 130.

Referring to fig. 8, when the locking of the second member 130 needs to be released, the nut 1602 may be rotated away from the second member 130 by screwing the nut 1602, and after the nut 1602 is rotated to a predetermined distance from the second member 130, the threaded rod 1601 may be rotated away from the notch 1301. Accordingly, the locking of the second member 130 can be released by rotating the threaded rod 1601 to the side of the notch 1301.

It should be noted that, for example, in the embodiment of the present application, the second member 130 may be driven to rotate by a driving device. For the driving device with the locking function, the first locking device 160 may not be provided, and after the second member 130 rotates to a position abutting against the product 200 to be tested accommodated in the accommodating cavity 1201, the second member 130 may be locked by the driving device. It should be noted that there are many forms of the locking device, and those skilled in the art can flexibly set the locking device according to actual requirements, only by making the locking device to maintain the second member 130 in the first state.

Further, referring to fig. 5 and 6, alternatively, in an embodiment of the present application, the second member 130 may be slidably disposed on the first member 120, and the second member 130 may be switched between the first state and the second state by sliding.

When the second member 130 slides to abut against the product 200 to be tested accommodated in the accommodating cavity 1201 in a direction close to the first member 120, the second member 130 may limit the product 200 to be tested in the accommodating cavity 1201.

Optionally, referring to fig. 5 and 6, in the embodiment of the present application, the jig may also include a second locking device 180. That is, in the embodiment of the present application, the locking device may be the second locking device 180. When the second member 130 abuts against the product 200 to be tested accommodated in the accommodating cavity 1201, the second locking device 180 may be used to lock the second member 130. Exemplarily, in the embodiment of the present application, the second locking device 180 may be embodied as a nut threadedly coupled with the guide bar 170.

It should be noted that, for example, in the embodiment of the present application, the driving device may be used to drive the second member 130 to slide. For the driving device with the locking function, the second locking device 180 may not be provided, and after the second member 130 slides to the position abutting against the product 200 to be tested accommodated in the accommodating cavity 1201, the driving device may be used to lock the second member 130.
