Description

USB connector

Technical field

The utility model relates to a kind of electronic device connector, relates more specifically to a kind of USB connector.

Background technology

Continuous development along with electronic product, between the various electronic products and the connection between the peripheral device more and more frequent, and realize being connected by USB connector between electronic product and its peripheral device is a kind of very common connected mode, so the frequency of utilization of USB connector also increases thereupon.USB connector is used so widely at electronic applications, the user is also more and more higher to the requirement of its quality, for satisfying the requirement of user to the USB connector quality, the quality that each manufacturer improves USB connector one after another from every side make its with aerial lug between be connected more solid and reliable.

Fig. 1 and Fig. 2 have showed the structure member of USB connector in the prior art.This USB connector comprises: metal shell 100, a plurality of conducting terminal 120 and insulating body 130.Described metal shell 100 is surrounded by relative upper surface 140, lower surface 150 and relative two sides 160, and is formed with opening 141 at the front end of described metal shell 100.Described two sides 160 respectively outwardly-bent horizontal-extendings form weld part 161, solder contacts 101 welding on described weld part 161 and the described pcb board 110, thus whole described metal shell 100 is fixed on the described pcb board 110.Described a plurality of conducting terminal 120 is arranged on the insulating body 130, and described insulating body 130 is provided with a plurality of and described conducting terminal 120 corresponding grooves (figure does not show), and described conducting terminal 120 all is fixedly mounted in the described groove; Another concave surface of the described relatively groove of described insulating body 130 forms a plurality of draw-in grooves 131, correspondingly, the upper surface 140 of described metal shell 100 inwardly protrudes out and forms a plurality of block tongues 142, when mounted, described block tongue 142 snaps in the described draw-in groove 131, thereby described conducting terminal 120 and described insulating body 130 are fixed in the described metal shell 100 together.

In use, when aerial lug inserts in the described metal shell 100 by described opening 141, if the operator is firmly excessive, and make copper foil on the described solder contacts 101 be subjected to the active force of bigger horizontal direction, then cause copper foil loosening easily, so repeatedly use copper foil will be come off from described pcb board 110; In addition, when if the operator upwards pulls described USB connector accidentally, then described weld part 161 will be subjected to the bigger tractive effort that makes progress, and may described copper foil be torn from described pcb board 110, thereby described weld part 161 is become flexible with the appearance that is connected between the described pcb board 110.Above-mentioned two kinds of situation service times are long all will make between described weld part 161 and the pcb board be connected insecure, cause loose contact between weld part 161 and the pcb board 110 easily and make described USB connector cisco unity malfunction, also influence the useful life of described USB connector simultaneously.

The utility model content

The purpose of this utility model is to provide a kind of USB connector at above-mentioned the deficiencies in the prior art, described USB connector can increase and pcb board combination power from a plurality of directions, to strengthen the fastness that is connected between described USB connector and the described pcb board, prolong the useful life of described USB connector.

For achieving the above object, the utility model provides a kind of USB connector, this USB connector is suitable for being welded on the pcb board, and comprise: plurality of conductive terminals, accommodate the insulating body of fixing described plurality of conductive terminals and coat the metal shell of described insulating body and described conducting terminal, described metal shell front end forms opening, wherein, the relative two sides of described metal shell are provided with outside bending and horizontally extending first weld part, to weld with described pcb board mounted on surface, the relative two sides of described metal shell also are provided with second weld part of downward extension.

As mentioned above, the utility model USB connector is on being welded to pcb board the time, because outwards bending and horizontal-extending form second weld part respectively in described two sides, make and increased two places welding between described USB connector and the described pcb board, thus make between described USB connector and the described pcb board be connected more firm; And described second weld part can be welded on the solder contacts of described pcb board lower surface, thereby can bear bigger active force perpendicular to described pcb board direction, thereby when described USB connector is subjected to upwards active force because of the careless manipulation accident, can prevent that copper foil from tearing from pcb board, therefore strengthen the connectivity robustness between described USB connector and the described pcb board, and prolonged the useful life of described USB connector.
