Abstract
The utility model discloses a connecting piece and in particular relates to a USB connecting piece, comprising a connecting piece body. The connecting piece body comprises a plug-in portion for plugging purpose. An annular metal housing, which is a seamless metal tube, is disposed at the outer side of the plug-in portion. The utility model overcomes the problems that top walls of metal housings of conventional USB connecting pieces are provided with gaps and impurities easily enter into the conventional USB connecting pieces via the gaps, and provides the novel USB connecting piece. The whole metal tube of the USB connecting piece with such a structure is designed in a closed manner without a gap, so that impurities are effectively prevented from entering into the USB connecting piece body, thereby improving the transmission precision of the USB connecting piece, prolonging the service lifetime of the connecting piece and reducing the use cost.
Description
Technical field
The utility model relates to a kind of connector, particularly relates to a kind of USB connector.
Background technology
along with the computer hardware develop rapidly, ancillary equipment is increasing, keyboard, mouse, flash disk, MP3 walkman etc. is well-known already, these equipment are all to dock with abutment element by the USB connector, Fig. 1 is traditional USB connector, comprise connector main body 1 ', establish the Plug Division 4 ' of docking for abutment element on connector main body 1 ', Plug Division 4 ' arranged outside has endless metal shell 2 ', metal-back 2 ' is formed by the compacting of sheet metal sheet, rectangular shape, compacting sheet metal joint out forms a tiny gap 3 ', the permanent use, gap 3 ' often can enter impurity, on the inveteracy electrical chip that overlays in connector main body 1 ' of impurity, thereby make connector main body 1 ' poor electric contact in use, transmitting accuracy reduces, even cause abutment element can not read out, and impurity is easy-clear not also, often need to change the USB connector.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of USB connector that can improve USB connector transmitting accuracy and extend the USB connector life-span.
USB connector of the present utility model comprises connector main body, and described connector main body comprises the Plug Division for grafting, and the outside, described Plug Division is provided with the endless metal shell, and described metal-back is the gapless metal tube.
USB connector of the present utility model is established through hole on the roof of described metal-back.
USB connector of the present utility model, described metal tube are aluminium-alloy pipe.
USB connector of the present utility model, described metal tube are rectangular tube.
USB connector of the present utility model, the number of described through hole are two.
Compared with prior art the beneficial effects of the utility model are: because metal-back is the gapless metal tube, metal tube integral body is closed design, gapless, effectively like this prevented that impurity from entering in the USB connector main body, thereby make the transmitting accuracy of USB connector improve, and extended the useful life of connector, thereby reduced use cost.
Description of drawings
Fig. 1 is the structural representation of traditional USB connector;
Fig. 2 is the structural representation of the utility model USB connector embodiment one;
Fig. 3 is the structural representation of metal-back in Fig. 2.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Referring to Fig. 2 and Fig. 3, a kind of flash disk, flash disk is provided with the USB connector, the USB connector comprises connector main body 1, and connector main body 1 comprises that 4 outsides, Plug Division are provided with endless metal shell 2 for the Plug Division 4 of pegging graft, metal-back 2 is the gapless metal tube, metal tube is rectangular tube, establishes through hole 3 on the roof of metal-back 2, and the number of through hole 3 is two.
Metal tube integral body is closed design, has effectively like this prevented that impurity from entering in connector main body 1, thereby makes the transmitting accuracy of USB connector improve, and has extended the useful life of connector, thereby has reduced use cost.
Described metal-back 2 can be completed according to following processing step:
Mold pressing: getting metal circular tube is raw material, and metal circular tube is placed in die, establishes formation die core in die, and pipe is carried out extrusion modling, makes its distortion, and the tube wall of the tubing after mold pressing leaves allowance should be less than 0.01mm;
Punching: the workpiece after extruding carries out holes punched on surface, and during punching, workpiece will fix;
Surface treatment: the workpiece after punching is carried out surface sand-blasting, reach the requirement of product.
Comprehensively above-mentioned, embodiment in the utility model is because metal-back 2 is the gapless metal tube, metal tube integral body is closed design, effective like this impurity of having avoided enters the USB connector, thereby make the transmitting accuracy of USB connector improve, and extended the useful life of USB connector, thereby reduced use cost; Metal-back 2 adopts mold pressing-punching-sandblast to make, and can produce in batches, improves enterprises production efficiency, should be pointed out that the utility model USB connector is applicable to keyboard, mouse, flash disk, MP3 etc. with the product of USB interface.
Only preferred implementation of the present utility model from the above; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
