Description

The USB electric connector

Technical field

The utility model relates to a kind of USB electric connector, is meant the structural improvement of a kind of B-type USB electric connector at its metal shell especially.

Background technology

TaiWan, China patent announcement M312071 discloses a kind of USB connector metal shell structure.See also Fig. 1, it is the three-dimensional structure diagram of USB connector metal shell structure in the known technology.This metal shell structure is made of a housing section PA1 and a cover body part PA2, housing section has a base plate PA11, two side plates (only indicating PA12 because of angular relationship among the figure) and a top board PA13, these two side plate PA12 are extended upward by base plate PA11 and form, top board PA13 is connected in the first half upper end of these two side plate PA12, makes housing section PA1 have an opening on latter half of top.Cover body part PA2 one is connected in housing section PA1 and covers this opening.Wherein, base plate PA11 extends one first double team sheet PA14, and cover body part PA2 extends one second double team sheet PA22.

Yet as shown in Figure 1, when cover body part PA2 covers this opening, two lid side plates (only indicating PA21 because of angular relationship among the figure) that cover body part PA2 extends downwards with its both sides contact with side plate PA12.So, cover body part PA2 and side plate PA12 cover contact area, the upper end of the lower end of lid side plate PA21 and side plate PA12 only, cover in the manufacture process of this opening at cover body part PA2, too small because of lifting surface area easily, produce in downforce under the situation of some displacement deviations, produce cover body part PA2 is not aligned with this opening thereupon being offset problem, cause the fine ratio of product of metal shell structure to descend.

In addition, when the metal shell structure connected wire rod, ground wire wherein often there is no especially it is fixed and only is placed in the metal shell, often produces the problem of ground wire landing displacement in metal shell.

The utility model content

Technical problem and purpose that the utility model institute desire solves:

As previously discussed, in known technology, exist cover body part and housing section side plate cover contact area too small, make the easy stressed skew of cover body part, and the suitably fixing problem of ground wire.Therefore, main purpose of the present utility model is to provide a kind of USB electric connector, it is in the upper edge portion of the side plate of the housing section of metal shell, lower edge part with the lid side plate, protrude out an at least one housing ribs and a lid ribs respectively, by housing ribs and contacting of lid ribs compression area is strengthened, be difficult for being offset thereupon because of the skew of pressure.And the first double team sheet of USB electric connector of the present utility model has a ground wire bare terminal end, ground wire suitably can be gripped and avoids coming off.

The technological means that the utility model is dealt with problems:

The utility model comprises a metal shell for the technological means that problem adopted that solves known technology for a kind of USB electric connector is provided.In an embodiment of the present utility model, the USB electric connector more comprises an insulating body, a plurality of terminal and a side cover.Metal shell can be divided into a front section and a back section, comprises a housing section and a cover body part, and wherein housing section comprises a base plate, two side plates and a top board.

Base plate is made up of one first cover plate, one second cover plate and one first double team sheet.The side that first cover plate and second cover plate are interlocked has corresponding catching groove and protruding button respectively, and this protruding button is fastened on this catching groove.The first double team sheet extends from the first cover plate one, and has a ground wire bare terminal end.This two side plate is extended to form by one on base plate two side direction, and has at least one housing ribs in upper edge portion.Top board is connected in the upper end of two side plates in one piece and forms an opening.Cover body part covers this opening and extends downwards two lid side plates, and the lower edge part of these two lid side plates has at least one lid ribs that should the housing ribs.The utility model effect against existing technologies:

From the above as can be known, the side plate contact area of the lid side plate of cover body part and housing section is too small in the known technology, easily produce the problem of skew during pressurized, in USB electric connector provided by the utility model, because the upper edge portion at two side plates of housing section has at least one housing ribs, partly has the lid ribs that at least one pair of should the housing ribs at the lower edge of two lid side plates of cover body part, can increase the contact area of lid side plate and side plate, apparently, by technology provided by the utility model, in the time of can avoiding that cover body part is covered on the opening of housing section because compression area too small cause cover body part to the relative position of housing section easily because of the pressure skew problem of skew thereupon.

The specific embodiment that the utility model adopted will be further described by following embodiment and accompanying drawing.
