Problems solved by technology
The upper and lower rows of contact parts are rigidly connected together through the connecting part. When elastically deformed, the stress is concentrated at the connecting part, and the force arm is short, and the existing current transmission requires electroplating rhodium ruthenium to further increase the hardness of the conductive terminal. During elastic deformation, it is easy to cause the risk of cracking or even breaking of the upper and lower rows of contact parts at the connecting part

A USB plug with positive and negative insertion, comprising an insulating body provided with several terminal slots in the front and rear directions and a number of conductive terminals inserted in the terminal slots, the front end of the insulating body is formed with a plugging cavity, and the terminal slots are connected from the rear It penetrates forward into the insertion cavity, the terminal slot includes a partition and the first and second slots separated by the partition, and each conductive terminal includes a corresponding plug inserted into the first and second slots. First and second terminals, the first and second terminals both include solder feet exposed at the tail of the insulating body, a holding portion extending forward from the solder leg, and extending forward from the holding portion to The elastic arm in the insertion cavity, the upper and lower sides of the holding part are respectively formed with first and second support parts, and the top or bottom surface of the first and second grooves and the partition plate are respectively formed with the first and second support parts. Describe the first and second fulcrums against which the first and second supporting parts are supported. In this application, the conductive terminal of the USB plug inserted in the front and back has better toughness.
Description
technical field [0001] The invention relates to the field of electrical connectors, in particular to a front and back USB plug of stamping parts and a manufacturing method thereof. Background technique [0002] Patent application No. 201721371940.7 of the People's Republic of China discloses a USB plug with positive and negative insertion, including an insulating body, a number of conductive terminals and metal buckles.
