USB-TYPE-C connector and manufacture method thereof

Abstract

The invention discloses a USB-TYPE-C connector and a manufacture method thereof. The connector comprises Pin needles, a plastic main body, two EMC elastomers, two hooks, a plastic back plug, a resistance and an iron shell; wherein an A1 Pin, a B1 Pin, an A12 Pin, a B12 Pin stamp into a whole to form a GND Pin group; an A4 Pin, an A9 Pin, a B4 Pin and a B9 Pin stamp into a whole to form a VBUS Pingroup; the inner portion of the plastic main body comprises a first hole site clamping all Pins and a second hole site clamping the two hooks; the upper and lower surfaces of the front end of the plastic main body are respectively provided with one EMC elastomer; the rear end of the plastic main body is provided with the plastic back plug; the rear end of the plastic main body comprises a penetrating hole site, the hole site is used for fixing the resistance; one end of the resistance is connected with an A5 Pin, and the other end of the resistance is connected with the VBUS Pin group; and theiron shell sleeves on the plastic main body. The USB-TYPE-C connector and the manufacture method thereof have the advantages that the cost is saved, the processing technology is simplified, and the safety performance of the connector is increased.

Description

technical field [0001] The invention relates to the field of USB connectors, in particular to a USB TYPE-C connector and a manufacturing method thereof. Background technique [0002] The USB Association announced a new type of connector: the USB TYPE-C connector. The association standard has the following requirements for the pin position of the male connector of the USB 2.0 specification: [0003] (1) GND Pins (A1, B1, A12, B12) need to be short-circuited together, and solder the GND ground wire; VBUS Pins (A4, B4, A9, B9) need to be short-circuited together, and solder the VBUS power line. [0004] (2) A 56K ohm resistor needs to be connected between PinA5(CC) and VBUS Pin. [0005] The current basic practice in the industry is to divide the pins into upper and lower rows, and put the pins into the mold by injection molding to make a combination of upper and lower pins; then put the two insert molded pins together , insert the plastic body, and put it into the iron shell...

AI Technical Summary

Problems solved by technology

Therefore, when soldering the pads on the PCB, it is easy to have poor soldering, false soldering, open circuit or poor contact. When any one of the two sets of short-circuited pins has these poor soldering, the product is fatal. Functional defects, this point is the most important defect

[0008] Because the pins are relatively small, it is very easy to cause the pins to be deformed when inserting the PCB between the upper and lower rows of pins. Once the pins are deformed, they cannot be aligned with the pads on the PCB, resulting in poor soldering.

[0009] Combine the two combined pins and then insert them into the plastic body. This assembly process is also due to the small size of the pins. It is easy to deform the contact part between the pins and the female seat, resulting in fatal product failure.

[0010] Therefore, the existing USB TYPE-C connector has fatal functional defects and low safety performance
