Description

The structural improvement of the carry-on dish of USB

Technical field

The utility model relates to electrical type, and the structural improvement of the carry-on dish of particularly a kind of USB refers to the structural improvement of a kind of simple structure and the carry-on dish of USB cheap for manufacturing cost especially.

Background technology

The carry-on dish of USB has been quite general portable memory device, generally speaking, the carry-on dish cording of USB has a USB joint, for being plugged to the main frame that generally has the USB slot, in notebook computer and the adapter, and at present on the market the joint system of the carry-on dish of USB is made up of a metal shell and an insulator, and be provided with plural USB terminal in the insulator, be positioned at USB joint rear end and then be welded with printed circuit board (PCB), then be combined with internal memory packaging part and all the other electronic building bricks on its circuit board, then utilize plastic housing to coat overall structure again, thus, make the carry-on dish overall volume of USB bigger, this problem of existence needs further to be improved.

The utility model content

The purpose of this utility model is to provide a kind of simple structure, volume little, and the structure of the carry-on dish of USB cheap for manufacturing cost.

The technical solution of the utility model is: the structural improvement of the carry-on dish of a kind of USB, it is mainly by housing, fixture and internal memory package board are formed, wherein be respectively equipped with an interface and be formed with an accommodation space with those interface places of communicating in the housing two ends, connect and to place in it for fixture by this accommodation space and interface, because fixture has been provided with a holddown groove, therefore can be fixed in this holddown groove and be placed in accommodation space for the internal memory package board, and internal memory package board system comprises adhesive body and circuit board, this circuit board system is located at this adhesive body one side surface, and circuit board is provided with a plurality of confessions one miniature digital card (Micro SD card) electric connection and fixing contact of saving from damage in surface system, and contiguous those contacts then are provided with plural USB contact point, so, more can reduce manufacturing cost by this kind structure, to promote whole competitiveness.

In addition, the structural improvement of the carry-on dish of described USB, wherein this housing is in be provided with one grade of portion away from the interface that wears this fixture; Be to be provided with plural first shell fragment on this contact; This circuit board be base plate for packaging (Chip On Board, COB); Those USB contact point systems are provided with plural second shell fragment.

Advantage of the present utility model is: simple structure and cheap for manufacturing cost.

Embodiment

As shown in Figures 1 and 2, be schematic perspective view of the present utility model and perspective exploded view, find out by knowing among the figure, this carry-on dish 1 is mainly by housing 10, fixture 12 and internal memory package board 14 are formed, wherein define an interface 102 respectively and be formed with an accommodation space 104 with those interface 102 places of communicating in housing 10 two ends, connect and to place in it for fixture 12 with interface 102 by this accommodation space 104, and housing 10 is in be provided with one grade of portion 106 away from the interface that wears this fixture 12, because defining a holddown groove 122, fixture 12 therefore can fix and be placed in accommodation space 104 for internal memory package board 14, and internal memory package board 14 is to comprise adhesive body 142 and circuit board 144, and circuit board 144 is provided with a plurality of confessions one miniature contact 162 of saving digital card 16 (Micro SD card) electric connection from damage and fixedly having plural first shell fragment 164 in surface system, and contiguous 162 of those contacts are provided with the USB contact point 168 of some second shell fragments 166 of plural tool.

By above-mentioned structure, form design, now be described as follows with regard to use situation of the present utility model, please cooperate simultaneously and consult accompanying drawing 3 and accompanying drawing 4, as shown in the figure, it is assembling schematic diagram of the present utility model, find out by knowing among the figure, at first, internal memory package board 14 is to comprise adhesive body 142 and circuit board 144, this circuit board 144 is a kind of base plate for packaging (Chip On Board, COB), and circuit board 144 is provided with plural contacts 162 in surface system, those connect and refer to that 162 are provided with plural first shell fragment 164 and electrically connect and be fixed on the circuit board 144 for the miniature digital card 16 (Micro SD card) of saving from damage, and in addition contiguous 162 of those contacts are provided with plural

USB contact point

168, and 162 are provided with some second shell fragments 166 in the contact.

In addition, because fixture 12 is to be provided with a holddown groove 122, therefore the above-mentioned circuit board of finishing after the assembling 144 can be inserted and is fixed in the holddown groove 122, then fixture 12 is arranged in housing 10 wherein in the interface 102 of an end, and be provided with one grade of portion 106 in the interface 102 of the other end, can avoid circuit board 144 to deviate from by fixture 12 and shelves portion 106, so, the miniature digital card 16 (Micro SD card) of saving from damage is located on the circuit board 144, and overall volume system is equal to general USB joint, manufacturing cost can not only be reduced, and its overall volume can be dwindled.
