In particular, it refers to an electronic card connector having a conventional electronic card connector with the prior art. And for the mechanism, in order to insert the card retracting operation, the elastic member of the ejecting mechanism is configured to have a sufficient degree of pre-compression or pre-stretching of the degree of elasticity. In the initial position, there is an object in which f is subjected to the property of the elastic member, and the most connected state is usually the use of the insulating body ^. The common electronics use surface-mount terminals, and when the elastic members, and most of the printed circuit boards, are used, the entire electronically mounted terminal is soldered to the ongoing heating process, and the workmanship is less than *°° and enters a high temperature furnace body. Softening occurs when the furnace is passed, and it is overheated. The insulating body will cause the insulating body to be produced, and the elastic force applied by the elastic member is normally used. The deformation occurs, and the step-by-step affects the crying of the card-returning mechanism. i C Announcement No. 6,875,033 discloses an electronic card ί ":, household =?; an insulating body with multiple terminals, a card-removing mechanism; The insulating body-side is disposed therein for the elastic direction of the i-card: the movable slider and the guide slot are fixed on the insulating body, and the other end can be moved along the center, and the Γΐ-end is stored. The spring element is located. The slider is disposed in the receiving cavity of the front end of the slider, but the structure can be shared by the insulating body and the metal casing. The design of the 7 and 4 structures merely reduces the insulation body. Cheng Wen J280702 II did not completely solve the problem, and its insulating body still has to withstand a 7-knife elastic force. Therefore, the deformation of the insulating body during the furnace is still not available. It is necessary to improve the existing electronic card connector. In order to overcome the aforementioned drawbacks in the prior art. [Invention] The present invention provides an electronic card connector in which the insulating body is less likely to be shaped in the furnace, thereby ensuring the positive operation of the card ejecting mechanism.

Buoyancy is not added to achieve the above object, and the present invention adopts the following technical solutions: a daughter card connector, and an electronic card The mating includes a plurality of sliders including a retracting arm and an elastic member. Therefore, in the front and rear directions of the dice, the retracting arm is located at the slider = ^, which can be electronically The card fits and can release the self-carding force from the electronic card. The front edge of the front edge of the casing is folded back to form a two-fold wall at the back of the field, and when the card-returning mechanism is located, The retaining wall respectively abuts and supports the block and the elastic member. The sliding phase of the subcardial mechanism is compared with the prior art, and the electronic card of the present invention utilizes the elastic force of the following work, which can avoid the insulating body being over The deformation caused by the two at the time of the furnace is to ensure the elastic force of the Pender's mechanical structure.

At this time, the two collision walls 43 supporting the slider 31 and the spring element 34 are applied with the edge body 1 straight wall 16 due to It is not affected by the elastic force of the card retracting mechanism. In addition, although the guiding member 33 is in contact with the straight wall, the end sliding in the heart-shaped guiding groove 312 is a free end, and does not -1280702 pairs of vertical walls. 16 applies an elastic force. Thereby, the g body 10 is subjected to the elastic force of the card ejecting mechanism 30, and the carcass 40 is used instead of the insulating body to be connected to the printed circuit board (not shown), thereby avoiding softening of the terminal 2 by soldering. In the state, it is subjected to the elastic force to cause the normal use of the body 3 in the 3 body. , and support, and then ensure that the card is returned, please refer to the first picture, the second picture and the second, ι is a rectangular shape, which can be self-insulating body 1Λ - : 斤不 'electronic card 100 large ^ Hai electronic card excitation Forward to insert people. The t-card 1 (K) is in the middle of the insertion process, and the end arm ^ comes into contact with the retracting arm 323 of the retracting mechanism 30, and drives the slider 31 to slide toward the W, and the spring element 34 is compressed while accumulating the elastic potential. The lead member 3 slides in the heart-shaped guide groove 312 until the slider 31 is locked in a latching position. At this time, the signal terminal 21 is electrically contacted with the conductive pad 1〇1 of the electronic card 1(). When the electronic card is withdrawn, the electronic card 1 is pushed forward again to release the latching action of the α-guide member 33 on the slider 31, and then the slider 31 drives the electronic card 1 under the action of the elastic restoring force of the spring element= 〇〇 Exit the electronic card connector.
