Abstract
The utility model discloses a novel universal serial bus (USB) 3.0 connector terminal structure, which comprises four first terminals and five second terminals and is characterized in that the second terminals comprises two pairs of signal terminals and a grounding terminal located at the middle of the two pairs of signal terminals. The main body of the grounding terminal extends backwards to from a plurality of branch terminals. The grounding terminal of the USB connector is divided into the plurality of branch terminals so that connection mode of connecting various ground wires and the grounding terminal in a circuit is optimized, and a plurality of ground wires are not needed to be twisted together to be connected with one single grounding terminal. Operation is more convenient during welding, thereby effectively reducing electro-magnetic interference (EMI), and being convenient to weld. The novel USB 3.0 connector terminal structure has the advantages of being simple in structure and easy to implement.
Description
Technical field
The utility model relates to the data transmission connector field, is specifically related to a kind of novel USB3.0 connector terminal structure.
Background technology
USB 3.0 has the backward compatibility standard, compatible USB1.1 and USB2.0 standard, the ease for use and the plug-and-play feature of tool tradition USB technology.USB3.0 adopts a kind of new physical layer, wherein, separates transfer of data with the affirmation process with two channels, thereby reaches higher speed.For backward compatible 2.0 editions; USB 3.0 has adopted the design of 9 terminals; Wherein the shape of four terminals and USB 2.0, definition are all identical, and other 5 be to prepare for USB 3.0 specially, comprise a pair of data output end, a pair of data receiver and an earth terminal.At present, in the USB manufacture process, connect ground wire in each bar circuit of signal terminal and be through concentrating and be connected with earth terminal after turning round line, in manufacture process, not easy to operate.And existing connector product structure disturbs and can not effectively avoid for EMI.
Summary of the invention
The technical purpose of the utility model provides a kind of novel USB3.0 connector terminal structure, overcomes the drawback that exists in the prior art.
The technical scheme of the utility model is a kind of novel USB3.0 connector terminal structure; Comprise the first terminal, second terminal; Said the first terminal has four; Second terminal has five, it is characterized in that: said second terminal comprises the earth terminal that two pairs of signal terminals are middle with being positioned at two pairs of signal terminals, and the main part of said earth terminal extends several branch's terminals to the back-end.
Further technical scheme also comprises:
The main part of said earth terminal extends three branch's terminals to the back-end.Two branch's terminals of both sides each with a pair of holding wire circuit in ground wire is connected, the centre branch's terminal be connected with outside ground wire, strengthened shield effectiveness effectively.
The rear portion of said second terminal is provided with some pits, utilizes the pit of these pitting shapes, can effectively improve the confining force of line and scolding tin during welding.
The beneficial effect of the utility model is:
Simple in structure, the manufacture process easy operating, and have good EMI shielded effects of jamming.
Description of drawings
Fig. 1 is the structural representation of earth terminal;
Fig. 2 is the structural representation of the utility model.
Embodiment
For technical scheme and the technical purpose of illustrating the utility model, the utility model is done further introduction below in conjunction with accompanying drawing and embodiment.
As shown in the figure; A kind of novel USB3.0 connector terminal structure; Comprise the first terminal 1, second terminal 2, said the first terminal 1 has four, and second terminal 2 has five; Said second terminal 2 comprises the earth terminal that two pairs of signal terminals are middle with being positioned at two pairs of signal terminals, and the main part of earth terminal extends three branch's terminals to the back-end.Branch's terminal in left side with circuit that two signal terminals in left side are connected in ground wire connect, branch's terminal on right side with circuit that two right-side signal terminals are connected in the ground wire connection, branch's terminal of centre is connected with outside ground wire.
The rear portion of said second terminal is equipped with the pit 3 of a lot of holes shape, increases the confining force between line and the scolding tin when being used to weld.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replacement or the technical scheme that obtained of equivalent transformation mode, all drop within the protection range of the utility model.
