Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1 to 3, the present embodiment discloses a USB connector testing connector, which includes an insulator and an elastic piece 2 accommodated in the insulator.

The insulator is provided with an accommodating groove 14 for accommodating the elastic sheet 2, and comprises a fixing part 11 and a plug part 12 extending forwards from the fixing part 11, wherein the thickness of the plug part 12 is smaller than that of the fixing part 11. One end of the fixing part 11 far away from the plug part 12 extends to form a cable fixing end 13, and the thickness of the cable fixing end 13 is smaller than that of the fixing part 11. In this embodiment, the width W of the plug portion 12 is 11mm, the length L1 of the plug portion 12 is 8.4mm, the height H1 from the bottom surface of the plug portion 12 to the highest position of the elastic piece 2 is 3.16mm, the height H2 of the fixing portion 11 is 6.38mm, and the length L2 from the end of the cable fixing end 13 to the end of the plug portion 12 is 15.75 mm.

The receiving groove 14 is partially located in the fixing portion 11 and partially located on the insertion portion 12, and the portion located on the insertion portion 12 has an opening on the upper surface of the insertion portion 12. A part of the elastic sheet 2 is bent to form a bent portion, the part is located in the receiving groove 14 on the insertion portion 12, and the bent portion of the bent portion is exposed on the upper surface of the insertion portion 12.

The insulator is made of a wear-resistant material, preferably, the insulator is made of wear-resistant nylon in the embodiment, and in other embodiments, the insulator may also be made of wear-resistant insulating materials such as wear-resistant rubber.

Preferably, the number of the elastic pieces 2 in the embodiment is four, a layer of gold is plated on the outer surface of the elastic piece 2, and one end of the elastic piece 2, which is located at the fixing part 11, is connected to the testing instrument through a cable. One end of the cable is fixed to the cable fixing end 13, and then the end is connected to the elastic sheet 2 by welding.

The outer side of the insulator is provided with a plastic rubber shell, the plastic rubber shell is provided with an accommodating groove, and the insertion part 12 is positioned in the accommodating groove of the plastic rubber shell and is used for inserting the USB connector.

As shown in fig. 4, the cable fixing end 13 of the USB connector testing connector is connected to a testing machine through a cable, and the testing machine is used for testing voltage, current, communication quality, and the like. The connector is mainly used for plugging and unplugging tests.

The connector is not provided with an iron shell, so that the product to be tested is prevented from being scratched, the insulator is made of a wear-resistant material, the wear resistance of the insulator is high, and the service life of the connector can be prolonged. Because the kink of flexure strip 2 exposes in the upper surface of grafting portion 12, when the USB connects grafting, the elasticity of USB joint touches and indicates with flexure strip 2 butt, can not direct contact grafting portion's upper surface, only contacts the lower surface of grafting portion 12, can reduce the friction to grafting portion 12, can effectively reduce the wearing and tearing to the insulator, can not rock because of the insulator receives wearing and tearing after the USB plug is pegged graft, can effectively reduce the erroneous judgement rate that the product detected. The service life of the connector can be increased from 5000 times to 50000 times, the service life of the connector is greatly prolonged, frequent replacement of the connector is avoided, and therefore the utilization rate of a test instrument is improved.
