Embodiment Construction

[0047] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are specifically cited below and described in detail with accompanying drawings.

[0048] In order to overcome the high production cost and complicated process caused by the Insert Molding process; the solder feet of the product are easily deformed and many other poor quality. The invention proposes an improved assembly structure, that is, high-strength flat terminals are directly assembled into the colloid, and no vertical injection molding machine is needed for insert molding, which avoids the problems of high production cost and unstable quality caused by the insert molding process.

[0049] Such as Figure 2a , Figure 2b and Figure 2c As shown, it is the assembly structure of a specific embodiment of the improved Micro USB of the present invention. The terminal 3 is inserted into the colloid 2 in parallel, wherein the colloid ...

Abstract

The invention discloses an improved MicroUSB (universal serial bus) interface and a manufacturing method thereof. The interface comprises a colloid and a plurality of terminals, wherein the colloid is formed by injection molding; the colloid is provided with a plurality of cavities for a terminal to insert in, and each cavity is provided with two main cavities; the plurality of terminals are flat-type terminals; each terminal is provided with a terminal contact crossbeam and a terminal clamp crossbeam, and is inserted into the colloid in parallel; each terminal contact crossbeam is inserted into one main cavity of the colloid; each terminal clamp crossbeam is arranged in the other main cavity of the colloid; and the colloid is subjected to injection molding by an injection molding machine, then the terminal is assembled in the cavity corresponding to the colloid, and finally the terminal is pressed in place by a laminated jig. The assembling manner has a simple process, and makes the adoption of automatic assembly possible; the capacity can reach 60-65K per day after automatic assembly; the terminal is in flat type and has high strength, and the weld leg is not easy to deform; thehead of the terminal dose not need to be connected with a conveying feed belt, thus effectively avoiding the damage of colloid after the material is broken.

Description

technical field [0001] The invention relates to a usb interface, in particular to a stable Micro usb interface capable of automatic assembly. Background technique [0002] USB is the abbreviation of Universal Serial BUS, which means "Universal Serial Bus" in Chinese. It is an external bus standard used to standardize the connection and communication between computers and external devices; the USB interface supports plug-and-play and hot-swappable functions of devices , and the USB interface can be used to connect up to 127 kinds of peripherals, such as mouse, modem, keyboard, mobile hard disk, DVD, etc., mobile phones, walkmans, etc. Since its launch in 1996, USB has become the preferred choice for personal computers and a large number of smart devices today. One of the necessary interfaces. [0003] There are currently three USB versions, the first generation: USB1.0 / 1.1, the maximum transmission rate is 12Mbps, launched in 1996. The second generation: USB2.0, the maximum...
