New Description: [New Technology Field] This creation relates to an electrical connector, and more particularly to a Micro-USB plug connector. [Prior Art] USB (Universal Serial Bus) technology is a widely used interface technology. Most consumer electronic products such as mobile phones, MP3s, digital cameras, and digital cameras use USB interfaces and computers for data transmission. In particular, with the miniaturization of these consumer electronic products, the USB interface of the Mini series has become a general-purpose computer data transmission interface. This is due to the USB's data transfer rate, ease of use (hot swappable), flexible connection (can connect 127 USB devices at the same time). As a result, almost all computer motherboards now offer a USB interface that allows peripherals to exchange data via the USB interface. However, the current USB technology is a computer-based interface technology that cannot exist independently of the computer. For example, a digital camera cannot connect to a printer via a USB interface for photo printing; and Ik is portable, such as a mobile phone, PDA, or digital camera. The trend of miniaturization, the current USB interface is relatively large, and has been developed for __ miniaturization. In order to solve this problem, a new USB standard, the Micr〇.B interface standard, has been replaced, which replaces the current universal Mini-USB interface. The corresponding Micro-USB connector conforming to the Mi.USB interface standard is also followed. produce. However, the Micro-USB connector has a much smaller Mini-USB connector. The size of the signal terminal is small, the material is fixed, and the shirt is easy to solder the terminal M327102. [New content] A Mier〇_USB plug connector is provided, which is easy to fix the terminal and facilitates soldering of the terminal. To achieve the above object, the present invention provides a Miero-USB plug connector 'includes a body, a plurality of terminals, a back cover, and a metal case. The body includes a base and a tongue projecting from the cypress, and a plurality of terminal slots are formed on the base and the tongue. The rear sill is disposed behind the base, the rear cover includes an abutting portion and a branch portion extending from the abutting portion, the abutting portion abuts against the base portion, and the abutting portion is provided with a plurality of terminal tail portions penetrating the abutting portion Slot. The plurality of terminals include a first terminal and a second terminal, and the first terminal and the second terminal are disposed in the plurality of terminal blocks. The rear end of the first terminal and the second terminal are disposed in the rear tail portion, and the end has a horizontal welded portion ′. the welded portion passes through the terminal tail _ and is turned on the support portion. A metal casing covers the body and the back cover. As described above, the creation of the Micro-USB plug connector allows the terminal to be held by the rear end portion of the rear cover without being moved backward by adding a rear cover, and the support portion of the rear cover can support the welded portion of the terminal. It makes the soldering work in the soldering part more convenient. In addition, the back cover can also isolate the soldering area and prevent the glue from overflowing. [Embodiment] The technical contents, structural features, and the achieved effects of the present invention will be described in detail. The embodiments are described below in detail with reference to the drawings.

The clip member 3 can also be provided with the tail protrusion 341 not at the upper and lower ends of the clip tail portion 34 at the clip tail portion 34. The side surface is provided with a convex cell or the rear cover is fixed in such a manner that the rear end projection 341 and the rear projection are not provided. The first terminal 2 and the second terminal 2 terminal tail portion 23 are inserted into the vertical portions of the terminal tail slots 43, 43. 432, and abut the rear end surface of the vertical portion 432 to prevent the first terminal 2 and the second terminal 2 from moving backwards during use; the first terminal 12 M327102 2 and the second terminal 2' of the soldering portion 24, 24, the abutting portion 41 of the rear cover 4 is placed in the corresponding opening 421 of the supporting portion 42 and abuts against the supporting portion 42, so that the first terminal 2 and the second terminal 2' have a larger welding area. To facilitate subsequent soldering operations. The creation of the Micro-USB plug connector 1 使 allows the first terminal 2 and the second terminal 2 ′ to be moved by the terminal tail slot in the rear cover 4 without adding a rear cover 4 At the same time, it is convenient to find the back cover 4 in the soldering portions 24 and 24 to perform soldering work. In addition, the back cover 4 also has a function of isolating the soldering area and preventing the glue from overflowing when the Micro-USB plug is connected to the H1〇〇 injection molding. Therefore, the back cover 4 has a high temperature of the body 1 and the area _ low soldering during soldering. The influence on the body 1 and the back cover 4 prevent the plastic from entering the slot through the gap between the slot and the thinner during the subsequent injection molding process. Referring to the tenth figure, after the rear cover 4 is assembled, the wires (not shown) connected to the inspection plug connector 100 are respectively soldered to the first portion exposed to the rear cover 4; a terminal 2 and a second terminal 2; 'The welded parts 24, 24, up. Then, the upper cover is mounted on the body 12, and the socket portion 52 of the upper cover 5 is sleeved on the tongue portion 12 of the main body. The engaging portion 33 of the connector 3 protrudes from the strip-shaped opening of the socket portion. The two upper cover side walls 54 are respectively disposed on the side of the base u, wherein the side wall arm M2 is placed in the second retaining groove 115 and abuts the upper cover bayonet of the top body L on the front body L. P 55 Then, the card is disposed at the recess of the lower surface of the base u, and the hole of the fastening portion is sleeved on the bump 112. Thereby, the upper cover 5 can be stably fixed on the body 1. Referring to the +H' lower cover 6 The retaining holes δ4 are disposed on the corresponding retaining blocks 541 of the upper cover side wall % 13 M327102, and the retaining blocks 611 on the lower cover 61 respectively extend into the first retaining grooves 114 of the lower surface of the corresponding base portion 11 The upper cover 5 and the lower cover 6 of the present Micro-USB plug connector 100 are stamped from a metal plate, and the upper cover 5 and the lower cover 6 are provided to improve the shielding performance and enhance the performance of the Micro-USB plug connector 100. Its overall strength, so that its electrical and physical properties are improved, so that the use is more stable. The upper card line of the Lee Society cover 5 and the lower card of the lower cover 6 The portion 63 rives the connecting wire (not shown), and the upper wire portion barb 531 provided on the upper wire portion 53 and the lower wire bar barb 631 provided on the lower wire portion 63 can enhance the tensile strength of the wire. Finally, a plastic jacket (not shown) is injection-molded on the upper cover 5 and the lower cover 6. During the injection molding, the liquid plastic can be filled into the space at the rear end of the rear cover 4, and the back cover 4 is fixed and cannot be withdrawn after solidification; The liquid collar can also flow into the first recess ln and the second recess η through the upper cover hole 511 of the upper cover 51 and the lower cover hole 612 of the lower cover 61 to strengthen the holding force of the plastic outer sleeve.
