[background technology]

At present, electronic card coupler is widely used in various portable digital electronics in a large number, as mobile phone, PDA(Personal Digital Assistant), digital camera etc., its structural design focuses on reaching best stability and to be connected effect, course of processing time and labour saving and cost of manufacture low.With the electronic card coupler shell, present way mostly is to be divided into two parts up and down according to actual size or internal configurations earlier, is engaged fixing again in modes such as spot welding, rivet or screws.Correlation technique can be consulted Chinese utility model patent CN No. 2358570, this connector shell is divided into the plastic cement body and covers shell, be provided with two opening draw-in grooves in the front end both sides of plastic cement body, two tabs corresponding with covering the shell front end are interlockingly connected, cover enclosure lid like this on the plastic cement body, form the receiving space of accommodating electronic cards.

Really, this kind structure can be assembled into the monolithic case of accommodating electronic cards, but because its parts are more, and contact is also many, if wherein have a size different slightly, then can cause the difficulty of fit on.Secondly, the area of the upper and lower shell of electronic card coupler is big, on the make reaches coplanar requirement and be to be difficult for overcome very much difficulty.Once more, because the upper and lower sheathing material difference of correlation technique, the thermal coefficient of expansion difference when causing being subjected to high temperature in manufacturing process, produces the internal stress pullled mutually and flexural deformation.Above problem can be brought the difficulty and the negative effect that is connected effect in the assembling inevitably.

[summary of the invention]

The purpose of this utility model be to provide a kind of part few, assemble reliable electronic card coupler.

The purpose of this utility model is achieved in that the utility model comprises insulation crust, is assembled in trip mechanism, terminal module and arrangement for detecting in the shell.Described shell is one-body molded by insulating material, comprising: upper wall, lower wall, antetheca, first and second sidewall, above-mentioned each wall surround one jointly and have the box-like cube of hollow that electronic cards is pegged graft and entered the mouth.Be provided with the opening of rectangle near the first side wall and electronic cards grafting porch at the shell upper wall, be provided with a gland that covers this rectangular aperture therewith accordingly, and antetheca is provided with the resettlement section of accommodating trip mechanism near a side of the first side wall, and lower wall then offers the U-shaped breach of assembling terminal module.In addition, four jiaos of places of lower wall outer surface are provided with the protruding button of positioning boss and location, and are provided with the accepting groove that holds arrangement for detecting in the intersection with second sidewall.

Compared with prior art, advantage of the present utility model is: this kind electronic card coupler shell is one-body molded, not only avoided the manufacturing process of common prior art loaded down with trivial details and to make the product error big, or the disappearance that easily gets loose of the connector shell integral body that assembles, it is many also to have overcome assembling parts, and contact is many, the shortcoming of assembling difficulty, effectively reach solid and reliable purpose, and simple in structure.
