Embodiment
Below in conjunction with accompanying drawing each preferred embodiment of the present utility model is made a more detailed description.
USB fixture of the present utility model comprises: a usb 1, this usb 1 comprises USB interface pedestal 12 and is coated on the base shell 11 of this USB interface pedestal 12, one main casing 2, these main casing 2 one distolateral breach that are provided with, described usb 1 is used to be fixed, one circuit board 3, this circuit board 3 electrically connects with described usb 1, and accommodates in described main casing 2; Wherein, end both sides of the described main casing 2 of connection are respectively arranged with one first protuberance 111 on described base shell 11; And be provided with two first through holes 311 in an end of described circuit board 3 31 correspondences; Described breach is passed in described base shell 11 1 ends, and first protuberance 111 on this base shell 11 inserts in first through hole 311 on the circuit boards 3, makes it to engage with this first through hole 311 is adaptive, strengthens the degree that is connected firmly of usb 1 and circuit board 3.
Further, described usb 1 is provided with a stage portion 13 at an end that connects described main casing 2, and this stage portion 13 is mainly used in the adaptive end 31 that described circuit board 2 is provided with first through hole 311 that accommodates.The inner space that can save described main casing 2 so is set, and described first protuberance 111 is separately positioned on the both sides of this stage portion 13.
Further, the cross section of described first protuberance 111 and first through hole 311 are non-circular setting, it can be for square, trapezoidal, triangle, oval or the like, described first protuberance 111 is positioned fixing in first through hole 311, promptly this first protuberance 111 fixedly engages with these first through hole, 311 rigidity, has strengthened usb 1 and circuit board 3 is connected and fixed degree, has improved the steadiness of USB fixture.
Further, device of the present utility model, the stage portion 11 of described USB interface pedestal 12 is provided with at least one second protuberance 121, correspondence is provided with at least one second through hole 312 on circuit board, this second through hole 312 engages with described second protuberance 121 is adaptive, wherein, these second protuberance, 121 preferable should being arranged between two first protuberances 111, described second through hole, the 312 preferable correspondences of answering are arranged between two first through holes 311.
Further, the cross section of described second protuberance 121 and second through hole 312 are circular the setting, and be set to two, this second protuberance 121 can rotate with respect to this second through hole 312 in second through hole 312, so be provided with, when the USB device was subjected to huge impact power, first protuberance 111 was fixed and is fractureed by rigidity in first through hole 311; Second protuberance 121 is being subjected to impulsive force, can rotate relative to second through hole, and impact power has cushioning effect, thereby can not be fractureed; At this moment, the USB fixture can make USB interface loosening because of fractureing of first protuberance, but can not come off, and can continue to use.
