Abstract
The utility model discloses an improved card connector with a card advancing and withdrawing device. The card connector is formed by matching an insulation base body, a metal lid and a card advancing and withdrawing device; wherein the card advancing and withdrawing device is arranged at the one side of the card connector, so as to control a memory card to be inserted and position and be withdrawn; the card advancing and withdrawing device comprises a sliding block, a spring, a brake bar and a dogging; the dogging has an upward limit lug and a limit groove which is positioned at the opposite position of the metal lid; the start up of the limit groove is a wide trench and extends inward to form a narrow trench; the limit lug of the dogging is inserted into the limit groove and the travel of the withdrawn card, thus the limit plug can first pass the narrow trench and then returns to the wide trench. As the result, the spring arm of the dogging can be ensured from moving aside and the memory card is prevented from rising outward.
Description
Technical field
The utility model refers in particular to a kind of storage card generation bullet that can effectively prevent and takes off the card connector with advance and retreat card device that flies out relevant for a kind of card connector when moving back the card stroke.
Background technology
Known card connector, mainly combine with crown cap coupling and form by an insulating base frame, comprise the several terminals groove in the insulating base frame, member such as terminal and detection lug, and insulating base frame one side is provided with one group of advance and retreat card device, can insert the location and bullet takes off and withdraws from order to the control store card, described advance and retreat card device is normally by a slide block, one spring, one brake bar and a dogging are formed, when storage card inserts, utilize slide block pushing tow compression spring (or known person also utilize slide block expansion extension spring and reach identical purpose), make brake bar one end can be in the vacillate start and obtain the location of slide block guide channel, this moment, the elastic arm of dogging snapped in the draw-in groove of storage card, so promptly be positioning states after the storage card insertion; But when storage card will withdraw from, the dogging elastic arm breaks away from the draw-in groove of storage card once begin to be offset, slide block is under acting force of the spring, will clash into storage card, the situation that is easy to fly out suddenly (promptly be commonly called as fly card phenomenon) with regard to causing the card bullet to take off and since now storage card all with compact in the majority, so bullet takes off situation about flying out and more sees seriously, on not only using suitable puzzlement is arranged, also very easily cause the loss of card or impaired.
The utility model content
The technical problems to be solved in the utility model is: a kind of improved card connector with advance and retreat card device is provided, it can make lasting the colluding of dogging elastic arm hold storage card moving back of storage card in card stroke, therefore can prevent effectively that storage card from bullet occurring and taking off the situation that flies out.
Technical solution of the present utility model is: a kind of improved card connector with advance and retreat card device, comprise: an insulating base frame, a crown cap and advance and retreat card device, this insulating base frame is provided with several terminals, and pedestal one side is held and is provided with the advance and retreat card device, and crown cap and insulating base frame be the coupling cover, wherein:
Crown cap offers a stopper slot, and the starting point of this stopper slot is a broad groove position, and inwardly continues to extend and form an elongate slot position;
The advance and retreat card device is provided with a curved shape and rubber-like dogging, and the one end is an embedding portion, the other end is an elastic arm, and be provided with a upwardly extending spacing lug, spacing lug embeds in the stopper slot of crown cap relatively, and spacing lug can be provided with movably along with the stopper slot advance and retreat;
Be made up of above-mentioned, when card moved back the card stroke, spacing lug was progressively returned broad groove position by the elongate slot position, make the elastic arm of dogging in the stroke of elongate slot position, keep non-migration, and continue to collude and hold storage card, when spacing lug was returned broad groove position, the dogging elastic arm beginning was released out.
Characteristics of the present utility model and advantage are: the utility model is offered a stopper slot on the crown cap of card connector, and the starting point of this stopper slot is a broad groove position, and inwardly continue to extend to form an elongate slot position, and in the dogging of the set advance and retreat card device of stopper slot relative position, then be provided with a upwardly extending spacing lug, make spacing lug embed in the stopper slot, spacing lug can be moved along with the stopper slot advance and retreat, especially in moving back the card stroke, because spacing lug is progressively to return broad groove position from the elongate slot position, so can guarantee that the elastic arm of dogging can not be offset, make sustainable the colluding of dogging elastic arm hold storage card, when spacing lug was returned broad groove position, the spring of advance and retreat card device had been released and can have been finished, so can prevent effectively that storage card from flying the card phenomenon.

Embodiment
Following conjunction with figs. describes feature of the present utility model and advantage in detail:
As shown in Figures 1 to 4, the improved card connector with advance and retreat card device that the utility model proposes mainly comprises: an insulating base frame 1, a crown cap 2 and an advance and retreat card device 3, wherein:
Insulating base frame 1, it is provided with several terminals 11, pedestal one side hold be provided with one group advance and retreat card device 3, the example of this insulating base frame 1 is not limit, can be embodied as various structural forms such as single card slot (as implementing shown in the illustration) or compound card slot, insert use to be suitable for single or various storage card 4;
Advance and retreat card device 3, it comprises a slide block 31, one spring 32, one brake bar 33 and a dogging 34 (as shown in Figure 2), slide block 31 is subjected to spring 32 to hold start, has a guide rail groove 311 on the slide block 31, spring 32 holds the two ends pin 12 of being located at insulating base frame 1 and slide block 31,312, brake bar 33 two ends hook respectively are located at the hook groove 13 of insulating base frame 1 and slide block 31,313, make the start of can in the guide rail groove 311 of slide block 31, vacillating of brake bar 33 1 ends, and when snapping in location notch 314, obtain to locate, dogging 34 is embedded at slide block 31, be curved shape and have elasticity, one end is an embedding portion 341, the other end is an elastic arm 342, and be provided with a upwardly extending spacing lug 343 at select location, make spacing lug 343 can embed the stopper slot 21 interior (as Fig. 6) of crown cap 2 relatively, making spacing lug 343 is can advance and retreat along with stopper slot 21 to move;
