CN201408862Y - Novel pin structure of USB3.0 connector - Google Patents

Abstract

The utility model relates to a novel pin structure of a USB3.0 connector, which comprises a USB2.0 pin and a USB3.0 pin. The USB2.0 pin and a USB3.0 pin are juxtaposedly arranged; the terminals of thetwo groups of pins are arranged in a staggered manner; and a transversal gap is formed between the adjacent terminals. After the structure is adopted, two groups of metal terminals can be stamped atone time onto a same metal substrate, so as to not only save the one-time stamping time, but also save a haft of the consumed substrates compared with the prior required substrate. In addition, by adopting the pin structure, the automatic welding operation of the USB3.0 pin is convenient, and the manufacturing cost is reduced; and the electromagnet interference generated by smaller space among theterminals of nine pins juxtaposedly arranged can be immediately eliminated through the extension design of an earth terminal, so as to ensure the performance of the USB3.0 connector.

Description

A kind of pin structure of novel USB3.0 connector

Technical field:

The utility model relates to the data transmission connector technical field, refers in particular to a kind of novel pin leg structure of USB3.0 connector.

Background technology:

The USB connected mode is a computer and connected mode commonly used during peripheral hardware is connected and conveniently, constantly makes great efforts research and development through the researcher, from USB1.0/1.1 and USB2.0 era development to 3.0 epoch of prior USB.Known USB2.0 adopts the design of 4 stitch, and USB3.0 has adopted the design of 9 stitch for backward compatible USB2.0, wherein the shape of 4 stitch and existing USB2.0 stitch, define identically, and other 5 stitch are to design for USB3.0 specially.On the arrangement mode of above-mentioned 9 stitch, prior USB 3.0 technology as shown in Figure 1, the main formula that is arranged above and below that adopts, be 4 stitch, one row of USB2.0,5 stitch, one row of USB3.0, the making moulding of this mode stitch needs 2 metal substrates, material cost and cost of manufacture height, and topmost difficulty is the automatic difficulty height of welding, the cost height.

The utility model content:

The purpose of this utility model is to overcome the above-mentioned weak point of prior art, and a kind of novel USB3.0 pin structure is provided, and to enhance productivity, to save cost, improves performance.

The utility model realizes that the technical scheme that its purpose adopts is: a kind of pin structure of novel USB3.0 connector, comprise USB2.0 stitch and USB3.0 stitch, described USB2.0 stitch and USB3.0 stitch are arranged side by side, and each terminal of these two groups of stitch is interlaced arrangement, and is provided with lateral clearance between the adjacent terminal.

The earth terminal of described USB3.0 stitch is terminal to be connected with the weld zone, and described weld zone horizontal expansion and cover all terminal lateral extent.

After the utility model adopted said structure, two groups of metal terminals can disposablely be stamped to form type on same metal substrate, have not only saved the punching press time one time, and the substrate that is consumed compare with the substrate of original needs also save near half; In addition, adopt the utility model pin structure, be convenient to the automatic weld job of USB3.0 connector, reduce manufacturing cost; Extension design by earth terminal can in time be eliminated because of the 9 stitch relative little electromagnetic interference that produces of spacing between terminal and the terminal side by side, the performance of assurance USB3.0 connector.

Description of drawings:

Fig. 1 is the structural representation of stitch in the existing USB3.0 connector;

Fig. 2 is the perspective view of the utility model USB3.0 connector stitch;

Fig. 3 is the planar structure schematic diagram of the utility model USB3.0 connector stitch.

Embodiment:

Below in conjunction with specific embodiments and the drawings the utility model is further specified.

As shown in Figure 2, it is the pin structure that a substrate 1 forms through one time punching molded back, be divided into two groups, one group is USB2.0 stitch 11, and number is 4, one group is USB3.0 stitch 12, number is 5, because two groups of stitch are molded on the same substrate 1 simultaneously, therefore two groups of stitch are the side-by-side setting, and be interlaced arrangement between each terminal of two groups of stitch, be provided with certain lateral clearance 13 between each terminal.

Furthermore, in 5 stitch of USB3.0, earth terminal 120 is connected with the weld zone 14 of substrate 1, and described weld zone horizontal expansion and covered 9 stitch lateral extent, can in time eliminate the electromagnetic interference that produces because of relative spacing is little between terminal and the terminal like this.

Obviously,, can on a strip-type substrate, punch forming overlap the stitch combination more, promptly as shown in Figure 3, more can save time and cost, enhance productivity according to technology enlightenment of the present utility model.

Claims (2)

1. the pin structure of a novel USB3.0 connector, comprise USB2.0 stitch and USB3.0 stitch, it is characterized in that: described USB2.0 stitch and USB3.0 stitch are arranged side by side, and each terminal of these two groups of stitch is interlaced arrangement, and are provided with lateral clearance between the adjacent terminal.

2. the pin structure of a kind of novel USB3.0 connector according to claim 1 is characterized in that: the earth terminal of described USB3.0 stitch is terminal to be connected with the weld zone, and described weld zone horizontal expansion and cover all terminal lateral extent.
