For the sake of simplicity of the drawing, the parts relevant to the present utility model are shown only schematically in the figures, which do not represent the actual structure thereof as a product. In addition, for simplicity and ease of understanding, components having the same structure or function in some of the figures are shown schematically only one of them, or only one of them is labeled.

Herein, "a" means not only "only this one" but also "more than one" case. Herein, "first", "second", etc. are used merely to distinguish one from another, and do not indicate their importance, order, etc.

Fig. 1 is a schematic diagram illustrating the structure of a test apparatus according to the present utility model. As shown in fig. 1, the testing device includes a cabinet 10. A movable base 30 is disposed in the cabinet 10, and the movable base 30 is slidably disposed in the cabinet 10. A cabinet door 101 and a test bench 20 are provided on the mobile base 30. The cabinet door 101 on the mobile base 30 can close the opening in the cabinet 10 after the mobile base 30 is slid into the cabinet 10. The test bench 20 is provided with a test position 21, and during testing, a product to be tested is placed at the test position 21 for testing. The product to be tested is provided with a mounting position for mounting the mounting piece. The mounting part can be various accessories such as a screw, a bolt, a sealing ring and the like, and the mounting position is the mounting position of the mounting part. For example, when the mounting member to be measured is a screw, the corresponding mounting position is a mounting hole of the screw. The mounting parts can be the same type of fittings or a combination of multiple types of fittings.

FIG. 4 is a schematic diagram of each test cell for a test bit. Fig. 5 is a schematic diagram for explaining a connection relationship between the wiring module and the on-off test unit. As shown in fig. 4, a plurality of on-off test units 210 (shown in fig. 2 and 3) corresponding to each mounting position are provided on the test bit 21. In fig. 4 and 5, the on-off test unit 210 is a test unit shown as E, F, G. As shown in fig. 5, the plurality of on-off test units are sequentially connected through cables.

The second connector 212 includes a second contact and a second terminal. The second contact is disposed opposite the first contact. When the product to be tested is placed on the test site 21, each on-off test unit corresponds to each mounting site, and when the mounting piece to be tested on the sample to be tested is correctly mounted, the first connecting piece 211 can move towards the second connecting piece 212 under the action of the corresponding mounting piece to be tested until the first connecting piece abuts against the second contact corresponding to the first connecting piece. Under the condition that all the installation pieces to be tested are correctly installed, the first contacts and the second contacts of all the on-off test units are contacted, and the loops connected with all the on-off test units are conducted. If part of the installation piece to be tested is neglected to be installed, the first contact and the second contact of at least one on-off test unit are not contacted and conducted, so that the loop is broken. The loop may be connected to a test power supply or to a communication line. When connected to a test power supply, it is possible to detect by means of current whether all the mounts to be tested are mounted correctly. When the device is connected to the communication line, if the to-be-tested mounting piece is missing, the device cannot work, and the test program reports an error notification so as to intercept the neglected-loading product in time for reworking.

One end of the return spring may be disposed on the first connecting member 211, and the other end is disposed on the corresponding second connecting member 212. Alternatively, one end of the return spring may be disposed on the first connector 211, and the other end is supported on the test site 21. After the first connecting piece 211 is pressed by the to-be-tested mounting piece towards the second mounting piece 212, the return spring can provide a return force for the first connecting piece 211, which deviates from the second connecting piece 212, so that the first connecting piece 211 can be reset in time after the to-be-tested product is taken down.

Referring to fig. 5, the plurality of on-off test units includes a primary on-off test unit 2101, an intermediate on-off test unit 2102, and a final on-off test unit 2103. The first terminal of the primary on-off test unit 2101 is connected to one end of the first test line 51.

Specifically, a probe a as shown in fig. 5 may be provided between the second terminal of the final on-off test unit 2103 and the test interface of the product to be tested to facilitate wiring. The first terminal of the intermediate on-off test unit 2102 is connected to the second terminal of the upper on-off test unit 210, and the second terminal thereof is connected to the first terminal of the lower on-off test unit 210. The intermediate on-off test unit 2102 may be designed according to the number of the mounting pieces to be tested, for example, when only two mounting pieces to be tested need to be tested, the intermediate on-off test unit 2102 may not be provided; when three mounting pieces to be tested need to be tested, a middle on-off test unit 2102 is arranged; when the number of the to-be-tested mounting pieces to be tested is greater than 3, the number of the intermediate on-off test units 2102 may be N-2. Each on-off test unit 210 is connected in series in the same loop, and a test point is formed between the first contact and the second contact in each on-off test unit 210.
