Description

A kind of USB Connection Block

Technical field

The utility model relates to a kind of connector construction, relate in particular to a kind of can promote with dock connector electrical contact stability prerequisite under the USB interface seat of lightening as far as possible design.

Background technology

Electronics technology is fast-developing now, the kenel that makes computer is for being developed into small volume, notebook computer easy to carry by desktop computer, and each corner in ubiquity society, when the user wants to carry out data, signal transmission or is connected with other interface equipment, namely need so-called interface equipment interface, and general interface equipment interface public use the most generally and widely on the market, still with general-purpose serial bus USB as main flow.

moreover, along with notebook computer, the electronic installation such as ultra-thin notebook computer deisgn approach is in gently, thin, short, little, and in order to make the electronic installation volume-diminished, therefore it is small but excellent close that the connector on the electronic installation internal circuit board needs, overall construction intensity also need with reinforcement, with in response to present development trend, and this universal serial bus connector also upgrades to the more specification pattern (USB3.0) of high-order again by early stage specification pattern (USB2.0), and the utility function of universal serial bus connector and the scope of application have been promoted, but due to existing such connector size standard commonly used, its width and length ending are fixed and can't reduce, to avoid because of hyoplastron dimension reduction leather-silhouette show overall construction intensity.If the hyoplastron dimension reduction will cause terminal group easily to withdraw from or the damage of other structure from hyoplastron.

the existing technical solution that proposes, as Fig. 8 and shown in Figure 9, three-dimensional exploded view and the side cutaway view of existing USB Connection Block, wherein the inner plural terminals groove of the pedestal A1 of this insulating base frame A institute tool A11 is for being equipped with terminal group B, and cover in insulating base frame A outside and be positioned with a shield shell C, and the first shell C1 inside of shield shell C institute tool is formed with the grafting space C10 that can stretch into for the hyoplastron A2 on pedestal A1, and has the chimeric hyoplastron A2 that is fastened on second housing C2 with respect to the shield C21 in the fitting portion A21 on the another side surface of terminal groove A11, just can be outside for covering in hyoplastron A2 by second housing C2, and be assembled to reduce the length dimension of shield shell C with the first shell C1, and whole structural strength after lifting insulating base frame A length reduction.

the mode of this shield shell C assembling is first with the mutual chimeric fixing of fitting portion A21 of shield C21 and the hyoplastron A2 of second housing C2, and after making hyoplastron A2 and pedestal A1 assembling, again hyoplastron A2 is pushed in the grafting space C10 of the first shell C1, the buckle C11 of its first shell C1 just can be held in second housing C2 and be positioned at draw-in groove C23 on locating clamp plate C22, and the elastic fastening plate C24 of this locating clamp plate C22 is held in the upper corresponding catching groove C12 of the first shell C1 to be combined into one, but can't once complete assembling when the first shell C1 of this kind shield shell C and second housing C2 assembling, and need to separately carry out assembling more than secondary, and cause assembling man-hour and cost significantly to increase, and because must having certain thickness, the package assembly of the first shell C1 and second housing C2 could strengthen unitary construction, to cause whole thickness relatively to increase, the place, space and the structural design of considering electric connector still has greatly improved, remaining to be engaged in this journey dealer redesigns effectively and is solved.
