Description

Connector ejection mechanism

The utility model relates to a card-removing mechanism for a connector, in particular to a card-removing mechanism for a connector that completely relies on the elastic force of an elastic body to allow an operator to press lightly to realize the card-removing mechanism.

A lever mechanism is commonly used in the card ejecting mechanism connected with the existing connector. As shown in FIG. 1 , a rocker 10 is pivotally arranged in front of the connector 19 . , forming a leverage mechanism. When the memory card 15 is inserted, the ejector plate 11 is pushed forward, and the push rod 12 is slid backward by the leverage of the rocker 10 (refer to the dotted line), and when the card is withdrawn, the push rod 12 is pushed forward, The ejector plate 11 is moved along the direction in which the memory card is inserted, and the memory card is pushed out. The existing lever design is more convenient in general use, but there are still the following disadvantages: the combination and separation of the memory card and the connector terminal, A certain insertion force and force application stroke must be applied. According to the design of the above-mentioned existing lever mechanism, a certain force must be applied to press the push rod, so that the ejector plate can generate enough force to overcome the insertion and extraction between the memory card and the connector terminal. Force, and the applied force should be sufficient to make the displacement of the ejection plate to actually disengage the memory card from the connector terminals. Therefore, it will be very convenient for the operator if the required force for returning the card can be reduced. Moreover, in the existing lever mechanism design, its handle 13 will protrude from the rear end 14 of the frame for a certain distance, and when the memory card is inserted and there is no When the memory card is inserted into the two states, the position of the push rod handle 13 is different from the front to the rear. This type of connector product is often used in small computers, such as notebook computers, electronic dictionaries, etc. How to reduce the size is an urgent problem that needs to be solved at present. The position of the push rod protrudes a certain distance from the computer casing, and the position of the push rod is different from the front to the rear, which is an unsatisfactory design for small computers. Therefore, how to improve the above shortcomings is an urgent problem in this field.

The purpose of the utility model connector card ejection mechanism is to provide a card ejection mechanism with the function of automatically popping out the card ejection. The elastic body stores energy by the card insertion force when inserting the card, and automatically ejects the card by the elastic force of the elastic body when the card is ejected.

Please refer to Fig. 2, which is an assembly perspective view of the card ejecting mechanism 4 of the present invention, a transverse element 20, and a longitudinal element 30. After being combined, it becomes a frame. The component 30 forms a receiving space between the horizontal component and the two vertical components for storing a memory card (not shown). In addition, the accommodating space is an insertion end relative to the transverse element 20, and the transverse element is provided with an electrical connection terminal 25 (see FIG. 3 ), and the inner side corresponding to the two longitudinal elements is provided with a guide groove 32 for guiding the insertion of the memory card. The horizontal element 20 and the two vertical elements 30 are fixed by a fixing plate 50, but the horizontal element 20 and the vertical element 30 can also be integrally formed or connected in other ways.

Please refer to Fig. 3, the card ejecting mechanism 4 of the present utility model comprises the following components, the push rod 40 is located in the slots 411, 421 of the two convex frames 41, 42 integrally extended by the longitudinal element, and the convex frames 41, 42 can be extended as longitudinal Sliding, the return spring 43 is accommodated between the two convex frames 41, 42, and the return spring penetrates into the slot 44 of the push rod 40. In addition, one end of the push rod 40 is a push handle 45, and the other end is a clamping portion 46. The clamping portion 46 is provided with a clamping concave surface 461. into the release groove 462.

Please continue to refer to FIG. 3 , the elastic body 60 is a corrugated sheet, which may also be in a sawtooth shape, and is arranged between the ejector plate 22 and the transverse element 20, wherein the ejector plate 22 can be driven to move longitudinally, and the elastic body 60 One end is fixed to the stop buckle 21 on the transverse element 20, and the other end is a lock part 61. In this embodiment, the lock part 61 and the elastic body 60 are integrally made, and the front end of the lock part 61 will be deformed by the elastic body. Shift to one side of the push rod 40, and make a locking connection with the push rod 40.

Referring to Fig. 4A and Fig. 4B, it is a state diagram of the interaction between the push rod and the elastic body in the card ejecting mechanism of the present invention and a partially enlarged cross-sectional view. The locking part 61 is provided with a notch 611 with a downward opening near the top. Its end edge is provided with a chamfered chamfer 612 downwards, and the bottom edge of the clamping concave surface 461 of the push rod 40 is also provided with a chamfer 463 on the side in contact with the locking part 61, when the memory card (not shown in the figure) When inserting, the ejector plate 22 presses the elastic body 60 by the insertion force, and the elastic body 60 deforms until the front end of the locking part 61 of the elastic body 60 moves laterally and contacts the clamping concave surface 461 of the push rod 40 (see FIG. 4B ), one end of the elastic body locking part 61 and one side of the clamping concave surface 461 of the push rod all have leading angles (612, 463), and the two leading angles at the moment of contact have a guiding effect (lead in) on each other, so that the locking Part 61 generates a thrust for a moment, forcing the locking part 61 to cross the bottom edge of the locking concave surface 461, and the slot 611 of the locking part 61 is locked in the locking concave surface 461 of the push rod 40 (see Figure 5). At this time, the memory card The docking with the terminal 25 is completed, and the elastic body 60 has already stored considerable elastic force, so that the memory card can be ejected automatically when the card is withdrawn.

Please refer to Figure 6, when the memory card is to be ejected, press the push rod 40 to move it to one side until the release groove 462 of the locking concave surface 461 moves to the position overlapping with the notch 611 of the locking part 61, this When the elastic body 60 returns to its original state in an instant, the memory card is ejected toward the insertion end by releasing the potential energy of the elastic force. At the same time, the push rod 40 returns to its original position due to the energy storage of the reset elastic body 43 .

Please refer to Fig. 5 again, according to the design of the present utility model, the distance A between the elastic body locking part 61 and the release groove 462 is the force application stroke of the push rod, and this distance A can be designed to be very short, so that the push rod The push handle does not need to protrude too much from the rear edge of the frame. For small computers, such as notebook computers, electronic dictionaries and other miniaturized designs, it has a good effect. The frictional force between the release grooves 462 is the card withdrawal force required for pressing the push rod. This frictional force is also smaller than the force between the missing groove and the release groove, so the utility model exerts force on the push rod when the card is returned. The card withdrawal force is very small.

The utility model is completely different from the existing lever-type card ejection design. It utilizes the ingenious combination between the wave-shaped elastic body and the push rod to realize that when returning the card, it only needs to press the push rod lightly, and the elastic body will automatically release the memory card. Ejection, small application force and short force application stroke, the handle of the push rod remains at the same position no matter whether the memory card is inserted or not, which can be used in industry.
