[0048] In the embodiment, the top plate assembly 200 is externally connected with a cylinder for pushing the top plate assembly 200 to move downward; the horn assembly 100 is internally provided with a horn for performing MIC leakage test on the products. Since the horn assembly 100 and the top plate assembly 200 adopt magnetic shielding materials, they have shielding effect on the magnetic field, so that the sound conduction meets the test requirements. The magnetic shielding materials are existing materials, and the embodiment preferably adopts 304 stainless steel plated with nickel and 304 stainless steel. The carrier plate assembly 400 is a carrier and is fixedly provided with the needle mold assembly 300, and the products are placed on the needle mold assembly 300. When the top plate assembly 200 moves downward, the pressing block of the top plate assembly 200 will press above the needle mold assembly 300, so that the probe 340 penetrates into the connector of the product, at this time, the product is connected to the line of the test equipment and starts the test. Therefore, it can be known that the embodiment improves the use materials of the horn assembly 100 and the top plate assembly 200, and through use verification, the magnetic field shielding effect is good, the leakage test meets the requirements, and it is suitable for simultaneously performing ICT test and leakage test.

[0051] A horn body 120 is fixedly arranged inside the horn shell 110;

[0052] A sound guide pipe 130 is fixedly arranged outside the horn shell 110 and communicates with the internal sound cavity of the horn shell 110.

[0053] The horn shell 110 comprises:

[0054] A horn fixing box 111;

[0055] A horn fixing plate 112, which, together with the horn fixing box 111, forms a cavity and fixes the horn body 120 inside the cavity;

[0056] A sound source adapter fixing plate 113, which is connected to the horn fixing plate 112 on one side and connected to the sound guide pipe 130 on the other side.

[0057] In the optimization scheme, the horn shell 110 comprises the horn fixing box 111, the horn fixing plate 112 and the sound source adapter fixing plate 113, which form a cavity, and the horn body 120 is arranged in the cavity, so that the magnetic shielding effect can be enhanced. The material of the horn shell 110 is 304 stainless steel plated with nickel, and a layer of sheet metal paint is sprayed in the inner cavity of the horn fixing box 111 (which wraps the horn body 120), so as to further isolate the magnetic field released by the horn body 120. The sound emitted by the horn body 120 is conducted to the upper part of the product through the sound guide pipe 130, and the sound guide pipe 130 has a structure of thick upper part and thin lower part and is externally locked by screws. The connection between the two is chamfered. The first support column 140 supports the horn shell 110 and is arranged on the ceiling 210.

[0058] In one optimization scheme, as shown in Figure 3 The structure of the ceiling assembly 200 is optimized. The ceiling assembly 200 comprises:

[0059] A ceiling 210, which is fixedly arranged on the side away from the carrier plate assembly 400 and fixedly arranged with the horn assembly 100. The ceiling 210 is made of magnetic shielding material;

[0070] A first needle die 310 for placing a product;

[0071] A second needle die 320 fixedly arranged on the carrier plate assembly 400 and connected to the first needle die 310 through an elastic member;

[0072] A third needle die 330 connected to the second needle die 320; a probe 340 sequentially passes through the third needle die 330, the second needle die 320, and the first needle die 310.

[0074] A carrier plate 410 provided with a recess and a bushing hole, and the needle die assembly 300 is arranged in the recess;

[0075] A bushing 420 arranged in the bushing hole.

[0076] In the optimization scheme, the first needle mold 310 is provided with a product positioning groove for positioning the product; the probe 340 has a ball head at the tail, which can be clamped on the hole of the third needle mold 330, the other end of the probe 340 passes through the third needle mold 330, then passes through the second needle mold 320, and enters the first needle mold 310. When the pressing block 270 presses the first needle mold 310, the probe 340 is pierced into the specified point of the connector, the other end of the probe 340 is connected to the specified point of the adapter plate, and the adapter plate is connected to the tester of the machine table. The current of the tester is connected to the product.

[0077] The optimization schemes of the above-described embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present application.

[0078] The specific working principle of the structure composed of all the above optimization schemes is as follows:

[0079] The carrier plate assembly 400 is fixed on the test station, the top plate assembly 200 moves downward under the action of the air cylinder, the top plate limiting block 250 contacts and the hydraulic buffer 240 plays a buffering role, reducing the speed of the pressing block 270 pressing the first needle mold 310. When the top plate assembly 200 moves, the pressing block 270 on the top plate assembly 200 is pressed on the first needle mold 310, so that the first needle mold 310 is attached to the second needle mold 320, and the probe 340 is pierced into the connector of the product. At this time, the product is connected to the line of the test equipment, and the test begins. After the test is completed, the top plate assembly 200 is retracted, and the first needle mold 310 is rebounded to the original position under the action of the elastic member.

[0080] The above only describes the preferred embodiments of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
