[0037] Please see Figures 1 to 8 The utility model embodiment provides a kind of multiple product simultaneous test equipment based on application turnover car, it mainly includes test host 1, at least one switching fixture 2 and at least one turnover car 3, wherein, test host 1 is provided with at least one test station 11 for being pushed into by turnover car 3, each test station 11 is provided with multiple electrically conductive strips 4 being spaced apart along horizontal direction and being electrically connected with test host 1, electrically conductive strip 4 extends along vertical, the material quality of electrically conductive strip 4 is preferably copper, specifically, test host 1 includes a fixed frame 12, the gap in horizontal direction of adjacent two electrically conductive strips 4 can be used to fixedly arrange electrically conductive strip 4 on fixed frame 12 along side, electrically conductive strip 4 is used to be inserted with first product 5 or be inserted with switching fixture 2, and this embodiment is preferably provided with two rows of electrically conductive strips 4 in vertical direction, to solve the problem that electrically conductive strip 4 is easily deformed due to length being too long, so that electrically conductive strip 4 can be accurately inserted with multiple first product 5 or switching fixture 2. Wherein, switching fixture 2 is used to carry multiple second product 6. Wherein, turnover car 3 is provided with multiple layers of storage space 31, storage space 31 can be used to carry first product 5, and storage space 31 can also be used to carry switching fixture 2 with second product 6. Specifically, switching fixture 2 includes at least two carrying areas 21, each carrying area 21 is used to carry a second product 6, and multiple first connectors 22 are arranged on the side of each carrying area 21, and multiple second connectors 23 electrically connected with first connector 22 are arranged at the rear end of switching fixture 2.

[0038] The first product 5 in the embodiment is taken as a load product, and the second product 6 is taken as a power supply product. The embodiment preferably sets two test stations 11 in the test host 1, and correspondingly applies two trolleys 3. The layers of the right trolley 3 are used to place the first products 5, the lower two layers of the left trolley 3 are used to place the first products 5, and the lower four layers of the left trolley 3 are used to place the second products 6. In use, the first products 5 can be placed on the corresponding layer of the trolley 3, and multiple second products 6 can be placed on the adapter jig 2 on the trolley 3, and the multiple second products 6 are all inserted with the corresponding first connectors 22. Then, the trolley 3 loaded with the first products 5 and the second products 6 is pushed into the corresponding test station 11 of the test host 1. Then, the first products 5 are pushed to make the connectors on the first products 5 inserted with the corresponding conductive strips 4.

In addition, the guiding structure 33 is arranged in each layer of the storage space 31, which is used to guide the first product 5 or the adapter jig 2 to move linearly along the first roller assembly 32 in the front and back directions, so as to improve the movement precision of the first product 5 or the adapter jig 2 during the process of being pushed in, and improve the reliability of the first product 5 and the adapter jig 2 being matched with the corresponding conductive row 4. The guiding structure 33 specifically includes the guide plates 331 arranged on both sides of the first roller assembly 32, and the width of the two guide plates 331 is adapted to the width of the first product 5 or the adapter jig 2, so as to ensure that the first product 5 or the adapter jig 2 can move linearly in the front and back directions accurately, thereby improving the reliability of the first product 5 and the adapter jig 2 being matched with the corresponding conductive row 4. In addition, the front end of the turnover vehicle 3 is also provided with the movable baffle 34, which can be moved and rotated to the path of the first product 5 or the adapter jig 2 moving forward away from the turnover vehicle 3, so as to limit the first product 5 or the adapter jig 2 from moving forward away from the turnover vehicle 3, prevent the first product 5 or the adapter jig 2 from being moved forward by mistake during the test, and improve the reliability and stability of the first product 5 and the second product 6 being tested at the same time.

In addition, the adapter jig 2 is provided with guide plates 25 on the left and right sides of the second roller assembly 24, the spacing between the adjacent two guide plates 25 is adapted to the width of the second product 6, so as to guide the second product 6 to move linearly in the front-rear direction along the second roller assembly 24, so as to improve the movement precision of the second product 6 when being pushed in or pulled out in the adapter jig 2, and improve the accuracy of the second product 6 being plugged into the first connector 22. In addition, the front end of the guide plate 25 is provided with a movable buckle 27, which can be operated to buckle the second product 6 after the second product 6 and the first connector 22 are plugged into each other, so as to lock the position of the second product 6, so that the second product 6 can be kept to be plugged into each other with the first connector 22, and the reliability of the electrical connection between the second product 6 and the adapter jig 2 is improved. Preferably, referring to Figure 3 The test station 11 is provided with an inductor 14 for sensing whether the second connector 23 on the adapter jig 2 is plugged into the conductive strip 4, the inductor 14 is a contact inductor, when the second connector 23 on the adapter jig 2 is plugged into the conductive strip 4, the conductive part 28 at the rear end of the adapter jig 2 will contact the inductor 14, so that the inductor 14 can determine that the second connector 23 on the adapter jig 2 is plugged into the conductive strip 4 according to the electric signal of the conduction, otherwise, if the conductive part 28 at the rear end of the adapter jig 2 does not contact the inductor 14, it indicates that the second connector 23 on the adapter jig 2 and the conductive strip 4 are in a state of not being plugged into each other.
