Definitions
- the present invention relates to a power connector for use in, for example, an in-vehicle audio device, a portable terminal, a personal computer, a peripheral device thereof, and the like, in which a so-called memory card is inserted and electrically connected.
- a power connector for use in, for example, an in-vehicle audio device, a portable terminal, a personal computer, a peripheral device thereof, and the like, in which a so-called memory card is inserted and electrically connected.
- this type of card connector includes a connector body having a card inlet at one end, and a plurality of card connection terminals provided at the other end in the connector body, and the card is inserted in the insertion direction.
- a so-called push-push type force-drawing mechanism that, when pressed, holds the card at a predetermined insertion position, presses the card again in the insertion direction, and then releases the card in the opposite insertion direction when released.
- the connectors shown in FIGS. 11 to 13 are provided with a cam groove 2 made of a so-called heart cam on a slide member 1 that moves together with a card, and the cam groove 2 is provided with an engagement pin connected to a connector body.
- the engagement pin 3 is configured so that the engagement pin 3 moves along the heart cam 2 as the slide member 1 moves. That is, in the connector, when the card is pressed in the insertion direction, the slide member 1 moves in the card insertion direction, and as shown in FIG. 11A, the engagement pin 3 is engaged with the first groove 2 a of the cam groove 2. Move from one end to the other.
- the engaging pin 3 moves from a predetermined position of the first groove 2a to one end of the second groove 2b as shown in FIG.
- the pin 3 is locked in a predetermined position in the second groove 2b.
- the card is held in the connector body.
- the engaging pin 3 moves from the other end of the second groove 2b to one end of the third groove 2c as shown in FIG. 11C.
- the engaging pin 3 moves to the other end of the third groove 2c as shown in FIG. 11D.
- the card is ejected from the connector body.
- the direction of movement of the engaging pin 3 is set in each groove 2a, 2b, 2c. Steps 2 d, 2 e, 2 f are provided, but these steps 2 d, 2 e, 2 f are gradually reduced by the repeated passage of the engagement pin 3 .
- the base end side of the engaging pin 3 is located at the center of the cam groove 2 in the width direction in the drawing, so that the engaging pin 3 is in the first groove 2a in the drawing as shown in FIG. 12A. Try to move along the right side (second groove 2a side). For this reason, as shown in FIG.
- the wall portion 2 g thus formed is cut so as to leave, and attempts to guide the engaging pin 3 to the second groove portion 2 b side. Also, the force that also removes the step 2 e between the first groove 2 a and the second groove 2 b.
- the inclined portion 2 e ′ formed by cutting the step portion 2 e of the second groove portion 2 b are close to each other, and are guided by the wall portion 2 g as shown in FIG.
- the engaging pin 3 tries to slide down from the slope 2 d ′ on the first groove 2 a side to the slope 2 e ′ on the second groove 2 b.
- the engagement pin 3 that moves from one end of the first groove 2a toward the other end does not move to the other end of the first groove 2a.
- the engaging pin 3 does not lock in the second groove 2b, for example, moves directly to the second groove 2b and moves to the third groove 2c as it is. There was a problem that it would not work.
- each groove 2a, 2b, 2c is made wider, the relationship between the slope 2d 'on the side of the first groove 2a and the slope 2e' on the side of the second groove 2b is increased.
- the sliding of the mating pin 3 can be prevented, but there is a disadvantage that the cam groove 2 becomes large by the width of the groove, and the slide member 1 becomes large.
- the present invention has been made in view of the above-described problems, and has as its object to prevent the width of the cam groove from being widened even when the inside of the first groove is cut by repeated movement of the engagement member.
- the engaging member When pressed, the engaging member moves from one end of the first groove of the cam groove to the other end, and when the pressing of the force is released, the engaging member moves from the predetermined position of the first groove to the second groove.
- the engaging member To engage the card at a predetermined position in the second groove, and when the card is pressed again in the insertion direction, the engaging member moves from the second groove to one end of the third groove, and when the card is released, the engaging member is engaged.
- Car that moves the joint member to the other end of the third groove An engagement member that moves from one end of the first groove to the other end of the first groove at least in the vicinity of the second groove in the first groove, on the opposite side of the second groove. Is provided with a guide unit.
- the engaging member moves in the first groove of the cam groove, the engaging member is guided to one end in the width direction (opposite to the second groove) by the guide provided in the first groove. Even if the vicinity of the second groove in the first groove is cut by the repeated movement of the engaging member, the portion where the first groove is cut is located on the opposite side of the second groove. It is formed as follows. Therefore, the first groove portion is cut without leaving a portion for guiding the engaging member to the second groove side, so that the engaging member does not move to the other end side of the first groove portion but directly to the second groove portion. Therefore, even if the inside of the first groove is cut, the function of the cam groove can be reliably maintained. In this case, since it is not necessary to increase the width of the cam groove, the size of the slide member is not increased, which is advantageous for reducing the size of the connector body.
- the guide portion is formed by making one end in the width direction of the bottom surface of the first groove lower than the other end.
- the engaging member in the first groove is connected to the other end in the width direction of the first groove.
- the engagement member can always be moved to the other end of the first groove because it is moved to the lower side of the guide portion and is reliably guided to the opposite side of the second groove.
