Description

The electronic cards device

The utility model relates to a kind of electronic cards device, particularly relates to a kind of electronic cards device that firmly can not get loose and can guarantee stable signal transmission of assembling.

Electronic cards mainly is plugged on the electronic card coupler, is used to transmit computer internal signal and computer outer periphery device signal.The structure of existing electronic cards comprises upper and lower metal shell, Insulating frame, circuit board and connector etc. substantially, wherein, connector is located at the relative two ends of circuit board, Insulating frame is used for circuit board is located, upper and lower two metal shells are divided into the upper and lower of Insulating frame, it are inserted and put fixing.Existing electronic cards assembling mode is with the peripheral riveted of upper and lower metal shell or be embedded in the periphery of Insulating frame with instrument pressing or inlay card technology.Similar design such as United States Patent (USP) the 5th, 242,310,5,339, No. 222.But existing fixed form with pressing, inlay card, make between upper and lower metal shell and have assembly clearance, can't fluid-tight engagement, add that the number of times of electronic cards plug is very frequent, so that it is loosening to cause the Insulating frame that is folded between the upper and lower metal shell to produce, and influences the normal use of electronic cards.Based on this, existing also have with integrated injection molding and fixing upper and lower metal shell of ultrasound wave hot melt mode and Insulating frame, makes both in conjunction with more firm, as United States Patent (USP) the 5th, 397, and 857,5,502, No. 892.Though this integrated fixed form is better than pressing mode, because it is not there is no the structure design of fastening between the upper and lower metal shell of one injection moulding and the Insulating frame, only, therefore, very firm behind the joint for the plane formula contact.

The purpose of the utility model electronic cards device is to provide a kind of assembling joint firmly to be difficult for getting loose, can guarantee the electronic cards device of stable signal transmission, the upper and lower metal shell of mat electronic cards device and Insulating frame are interfered assembling, can strengthen adhesion each other, and not too influence the contact engaging and separating force reduction, reach the purpose that increases the service life.

The purpose of this utility model is to realize like this, a kind of electronic cards device promptly is provided, integrated injection molding and ultrasonic heat welding are integrated, it comprises: upper and lower metal shell, it all is the rectangle plate body, major axis is respectively equipped with the composition surface in both sides, is provided with at least one hollow out body on described composition surface; Insulating frame has two edges at least, is located at the composition surface of described upper and lower metal shell accordingly, and described two edges are provided with the reinforced ribs that can be incorporated into this hollow out body corresponding to described hollow out body place; One circuit board is located on the described Insulating frame, and its at least one end is provided with connector communicatively.

The principal feature of the utility model electronic cards device is, the upper and lower metal shell of this electronic installation be positioned at the Insulating frame composition surface on, be provided with the hollow out body that runs through the composition surface, Insulating frame with respect to this hollow out body is provided with the reinforced ribs that edge is stuck in this hollow out body, by this when upper and lower metal shell is assembled into one, this reinforced ribs can be inlayed and be stuck on the hollow out body, makes both joints have axial drag, is difficult for breaking away from.

Another characteristics of the utility model electronic cards device are that this Insulating frame comprises that closing relatively is first framework and second framework of one, can be bonded into one with upper and lower metal shell respectively, again assembling mutually.

The advantage of the utility model device is that its upper and lower metal shell and Insulating frame are assembled into one, and are interference engagement, makes its one-piece construction firm, be difficult for loose, thereby realize stable signal transmission, the effect of long service life.
