New Description: [New Tear 4 Touch Area] This is a kind of connector, especially for a kind of metal _ _ _ 卡 clothing buckle on both sides, which can stabilize the fixed electronic card. The snap structure of the card connector. [Prior Art] The card connector of the present invention is used for assembling a memory module, such as a general DDR (Double-Data-Rate) SDRAM module, and has an insulating body. The memory module is inserted into one side of the memory module and electrically connected to the terminal fixed in the insulative housing for signal transmission. When the module is assembled, it is inserted into the insulating body from the top to the bottom, and then the other side of the memory module is pressed down to form a horizontal level. Therefore, a fixing mechanism must be provided to stabilize the memory. The other side of the body module prevents the memory module from bounce or horizontally. For example, the technique disclosed in the Patent No. 84,107,607, to the Republic of China, incorporates a metal latch mechanism directly on both sides of the casing for fixing the memory module. The latching mechanism is fixed on both sides of the insulating body by the slide rail assembly method 5 M331798, and the stability is not good, and the stopping tip is directly formed on the latch mechanism. When the memory module is assembled, the tip is stopped. The latching mechanism is directly moved by the direct force, so that the latch mechanism body is easily deformed due to excessive force. [New Content] > The purpose of this creation is to provide a snap-fit structure for a card connector, which is improved by this creation to simplify the production process and effectively reduce the production cost. The purpose of the present invention is to provide a snap structure of a card connector, which can effectively reduce the degree of deformation of the clip arm by the improvement of the present invention. The purpose of the present invention is to provide a snap structure of a card connector, which is effective in increasing the strength of the snap arm by the improvement of the present invention. The present invention provides a snap-fit structure of a card connector, comprising an elongated insulating body and a pair of snap arms; the insulating body is provided with a plurality of terminals and a card insertion slot; the snap arms are integrally formed of metal The device is manufactured and has three parts, a mounting portion, a main body portion and a locking device. The mounting portion is assembled on the bottom sides of the insulating body, and the locking device extends upward from the lower edge of the main body portion. And constitute. 6 M331798 [Embodiment] The following describes the preferred embodiment of the present invention. Please refer to the first to fourth figures. The snap structure of the card connector of the present invention is mainly composed of an insulative housing 10 and a pair of snap arms 2 The clip arms 2 are assembled on opposite sides of the insulative housing 10 . The structure of the insulative housing 1 is substantially a vertically long frame, and a plurality of terminals are disposed therein. The plurality of terminals can be further divided into a plurality of large terminals 31 and a plurality of small terminals 32, which can be respectively formed by the front side and the rear side of the insulative housing 10. The insulative housing 1 is inserted into the slot to be disposed on one side of the insulative housing 10. Therefore, the user can insert the side of the electronic card into the card insertion slot 11 to electrically connect the electronic card 90 to the plurality of terminals. The snap arm 20 is formed by integrally forming a metal, and is mainly composed of three parts: a mounting portion 21, a main body portion 22 and a circular arc portion 23 for stably fixing the electronic card 90 inserted into the insulative housing 10. Positioning. The mounting portion 21 is provided at one end of the main body portion 22, and the circular arc portion 23 is provided at the other end of the main body portion 22. When the latching arms 20 are assembled, the mounting portion 21 is mounted on the bottom sides of the insulative housing 10, so that the insulative housing 1 and the latching arms 20 together form a gate-shaped structure. Since the mounting portion 21 interferes with the bottom sides of the insulating body 10, when the card connector is soldered to the electric 7 M331798 board, the clothing port P21 can be stably fixed between the insulating body (7) and the circuit board. The technology has better structural strength. After the electronic card 90 is inserted and positioned, the arc portion 23 can be fitted to the two sides (four) slots 91 of the electronic card 90 to prevent the electronic card 9 () from being horizontally detached. In addition, in order to effectively fix the electronic card 9〇, the latch arm 2〇 further includes a mouthpiece 24, and the device 24 is extended upward from the lower edge of the main body portion 22, and is folded outwardly through the body portion 22. It is composed of shackles. During the clamping process of the electronic card 90, the fixing device is pressed and elastically moved backward, and then elastically restored, so that the fixing device 24 is relatively fixed above the electronic card 90, and the electronic card 9 () is popped up. Since the fixing device 24 is separately extended from the main body portion 22, when the fixing device 24 is elastically deformed by the force, the deformation of the main body portion 22 is extremely small, and the probability of deformation and damage of the main body portion 22 is relatively reduced. A stopper portion 24 is disposed at an upper edge of the fixing device 24, and a sub-stop portion 222 is disposed on the main body portion 22. The sub-stop portion 222 is spaced apart from the outer side of the stopper portion 241, so that when fixed When the device 24 is elastically moved, the stopper portion 241 and the main body portion 22, the stopper portion 241, and the sub-stop portion 222 act to prevent the fixing device 24 from being excessively moved in and out. In addition, a fixing portion 25 is further extended on the lower edge of the main body portion 22 of the latching arm 20 for soldering to the circuit board 8 M331798. The snap-fit structure of the card connector of the present invention has an integrally formed metal snap arm 20, which is easy to manufacture and can effectively reduce the production cost. By using the structure of the fixing device 24 extending independently, the degree of deformation of the arm 20 can be effectively reduced. In addition, by attaching the mounting portion 21 of the latching arm to the bottom of the insulative housing 1G, the latching arm 2G is stably clamped between the insulative housing 10 and the circuit board, thereby effectively increasing the strength of the latching structure. , ', not to the above, this creation has indeed met the requirements of the creation of patents, 提出 filed a patent application according to law. However, the above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, the shape, structure, characteristics and spirit described in the scope of the patent application are equally changed and modified. , should be included in the scope of the patent application of this creation.
