[0002] Electronic products with USB interfaces need to be quality inspected one by one after assembly. The existing technology usually uses finished USB-C or USB-A cables for direct insertion. This test method has many disadvantages. For example, the USB interfaces of finished cables are thin and soft metal sheets, which are easily deformed in the face of high-frequency plugging and unplugging, causing metal fatigue, which can easily lead to abnormal plugging and failure to plug in. The cost of replacing finished cables is high and it is difficult to meet production needs. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a USB interface test floating tooling. Since an adapter card is used in a modular assembly manner to provide an independent USB port with a chamfer, stress can be absorbed by the clearance formed by bolts and countersunk holes built on the module support, thereby significantly reducing metal fatigue, greatly extending the service life of the test interface, and effectively reducing the test cost.

[0005] In a preferred embodiment of the utility model, a plurality of countersunk holes are opened on the vertical wall, bolts for connecting module supports are inserted into the countersunk holes, countersunk grooves are arranged in the countersunk holes, springs for top-connecting bolts are installed in the countersunk grooves, and the diameter of the countersunk holes is larger than the diameter of the bolts to form a floating clearance.

[0006] In a preferred embodiment of the utility model, a USB-C interface or a USB-A interface is provided at the front end of the adapter card, a test USB flash drive electrically connected to the USB-C interface or the USB-A interface is provided at the rear end of the adapter card, and a transition chamfer is provided on the interface end face of the USB-C interface or the USB-A interface.

[0007] In a preferred embodiment of the utility model, a push-pull type quick clamp is arranged beside the slide, and the push-pull type quick clamp is connected to the slide via a transfer arm.

[0008] The beneficial effect of the utility model is that the utility model provides a USB interface test floating tooling, which adopts an adapter card to provide an independent USB port with chamfer in a modular assembly manner. Therefore, it can absorb stress through the clearance formed by bolts and countersunk holes built on the module support, thereby significantly reducing metal fatigue, greatly extending the service life of the test interface, and effectively reducing the test cost.

[0012] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] like Figure 1-2 As shown, the embodiment of the utility model includes:

[0014] A USB interface test floating tooling, comprising a platform 1, a test product base 2, a linear rail 3, a slide 4, a vertical wall 5, a module support 6, a screw 7, an adapter card 8, a spring ejector 9, a floating pressure block 10, and a avoidance opening 11. The platform 1 is provided with a test product base 2, linear rails 3 are arranged in parallel on both sides of the test product base 2, a slide 4 is mounted on the linear rail 3, a vertical wall 5 facing the test product base 2 is arranged on the slide 4, the vertical wall 5 is opened and equipped with a module support 6, an adapter card 8 fixed by screws 7 is arranged on the module support 6, spring ejector 9 is horizontally arranged on both sides of the adapter card 8 of the module support 6, a floating pressure block 10 is vertically mounted on the spring ejector 9, and a avoidance opening 11 matching the adapter card 8 is opened on the floating pressure block 10.

[0015] Among them, a plurality of countersunk holes are opened on the vertical wall 5, and bolts 12 connecting the module support 6 are inserted into the countersunk holes. A countersunk groove is arranged in the countersunk hole, and a spring 13 for connecting the bolts 12 is installed in the countersunk groove. The diameter of the countersunk hole is larger than the diameter of the bolt 12 to form a floating clearance.

[0016] Furthermore, a USB-C interface or a USB-A interface is provided at the front end of the adapter card 8, and a test USB flash drive 14 electrically connected to the USB-C interface or the USB-A interface is provided at the rear end of the adapter card 8, and a transition chamfer 15 is provided on the interface end face of the USB-C interface or the USB-A interface.

[0017] Furthermore, a push-pull type quick clamp 16 is arranged beside the slide 4 , and the push-pull type quick clamp 16 is connected to the slide 4 via a transfer arm 17 .

[0018] This tooling is mainly used to connect the product to be tested with the adapter card 8, that is, to connect the USB interface on the adapter card 8 to the USB interface of the product to be tested, and to test the interface signal quality and interface transmission performance by reading and writing data on the USB disk 14.

[0019] The specific operation method is:

[0020] First, place the product to be tested on the test product base 2, connect the test USB disk 14 to the adapter card 8, and power on the product to be tested and connect it to the back-end industrial computer.

[0021] Then, the vertical wall 5 on the slide 4 is pushed toward the test product base 2 by the push-pull quick clamp 16. During this process, the floating pressure block 10 first contacts the test product, causing the spring 13 ejector pin 9 to compress and buffer, and then the USB interface on the adapter card 8 contacts the USB interface of the product to be tested. In order to solve the metal fatigue and material loss caused by frequent impact on the interface, the module support 6 provides floating clearance through countersunk holes and bolts 12, and uses the transition chamfer 15 on the end face of the USB interface to absorb the impact. Therefore, compared with the connection solution of finished wires, the life span can be extended exponentially.

[0022] In addition, the adapter card 8 is fixed to the module support 6 by screws 7 to achieve convenient and rapid maintenance and replacement, thereby effectively reducing the test cost and providing good protection for the test USB flash drive 14 .

[0023] In summary, the utility model provides a USB interface test floating tooling, which adopts an adapter card 8 to provide an independent chamfered USB port in a modular assembly manner. Therefore, it can absorb stress through the clearance formed by the bolts 12 and the countersunk holes built on the module support 6, thereby significantly reducing metal fatigue, greatly extending the service life of the test interface, and effectively reducing the test cost.
