Description

  The present invention relates to a card connector device, and more particularly to a card connector device for electrically connecting a card such as a chip card or an IC memory card to a substrate in an electronic device such as a mobile phone.

  Conventionally, an elastic member that urges and brakes the slider in a direction opposite to the ejecting direction is provided in a space formed between the housing and the slider and on the card insertion slot side. The slider is urged by the urging force of the elastic member. There has been proposed a card connector device that prevents the card from popping out when the card is ejected (see, for example, Patent Document 1).

Japanese Patent No. 4268059

  However, in the card connector device described above, since it is necessary to provide a slider-dedicated member (elastic member) in the card ejection direction, the cost for the member dedicated to braking and the work for incorporating the member is included. This is one of the factors that hinder the manufacture of a card connector device at a low cost. Further, this is one of the factors that hinder the miniaturization of the card connector device due to securing the accommodation space for the members dedicated for braking.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a card connector device that can prevent a card from popping out without requiring a member dedicated to braking.

  The card connector device according to the present invention includes a housing for storing the card, a slider for moving the card between a mounting position and a discharging position in the housing, a biasing member for biasing the slider in the discharging direction, A card connector device comprising a spring member that is held by a slider and has an engaging portion that engages with a card as the card is inserted, wherein a part of the spring member is slid on a part of the housing. A sliding surface that receives an urging force by being moved and has a shape that increases the urging force from the spring member as the slider moves in the discharge direction is provided.

  According to the card connector, a sliding surface that receives a biasing force by sliding a part of a spring member having an engagement portion with the card is provided on a part of the housing, and the sliding surface is discharged from the slider. Since the urging force from the spring member is increased along with the movement in the direction, the slider is controlled by the spring member having an engaging portion with the card and a part of the housing along with the movement in the discharge direction. Since power can be applied, a spring member having an engagement portion with the card can be used as a braking member, and the card can be prevented from popping out without requiring a dedicated member for braking. .

  In the card connector device, displacement of the spring member in a direction in which the engaging portion is separated from the card is regulated in a process of moving the card between the mounting position and the discharging position on a part of the housing. On the other hand, it is preferable to provide a restricting surface that allows displacement of the spring member in a direction in which the engaging portion is separated from the card at the discharge position, and the restricting surface is disposed at a position corresponding to the sliding surface. . In this case, since the restricting surface for allowing or restricting the displacement of the spring member according to the position of the card is disposed at the position corresponding to the sliding surface, the spring is adjusted according to the contact position of the spring member with respect to the sliding surface. Since the engagement between the member and the card and the release thereof can be interlocked, it is possible to prevent a situation where the engagement between the spring member and the card is undesirably released.

  In particular, in the card connector device, it is preferable that the sliding surface and the regulating surface are formed on a common protrusion provided on the housing. In this case, since the sliding surface and the restricting surface are formed on the common protrusion provided on the housing, the single member has the slider braking function and the card engagement and release function. Therefore, the structure of the housing can be simplified.

  Moreover, in the said card connector apparatus, it is preferable to provide the said projection part in the movement area | region of the said slider. In this case, since a protrusion having a sliding surface and a restriction surface is provided in the moving area of the slider, it is not necessary to provide a space for arranging the protrusion in the card connector device. It is possible to reduce the size of the connector device.

  Furthermore, in the card connector device, it is preferable that the spring member is U-shaped, and the sliding surface and the regulating surface of the protrusion are sandwiched. In this case, since the sliding surface and the regulating surface are sandwiched by the U-shaped spring member, the structure of the spring member is simplified and the space for accommodating the spring member is reduced. Is possible.

  According to the present invention, a sliding surface that receives a biasing force by sliding a part of a spring member having an engaging portion with a card is provided in a part of the housing, and the sliding surface is provided in the ejecting direction of the slider. Since the spring member has a shape that increases the urging force from the spring member along with the movement of the slider, the spring member having the engaging portion with the card and a part of the housing apply a braking force to the slider along with the movement in the ejection direction. Since it can be given, the card can be prevented from popping out without requiring a member dedicated to braking.

  When the card 100 is pulled rearward from the state shown in FIG. 7, the engagement of the engagement portion 441 of the lock spring 44 with the recess 103 of the card 100 is released. As a result, the card 100 can be pulled out from the connector 1. FIG. 10 shows a state in which the card 100 arranged at the discharge position is pulled backward.

  Here, the relationship between the protrusion 262 and the lock spring 44 in the connector 1 in the state shown in FIGS. FIGS. 11A to 11D are enlarged views in the vicinity of the protrusion 262 in the connector 1 in the state shown in FIGS. In FIGS. 11A to 11D, the slider 4 and the engagement pin 7 are omitted for convenience of explanation.

  In a state where the card 100 is disposed at the ejection position, the lock spring 44 is in a state where the hook-shaped portion 441a of the engaging portion 441 is engaged with the concave portion 103 of the card 100 as shown in FIG. Yes. Further, the vicinity of the rear end portion of the arm portion 44 c connected to the urging portion 442 is in contact with the flat portion 264 on the sliding surface 261 of the projection portion 26. In this case, the urging portion 442 is in contact with the inner wall surface of the right side wall portion 22 at the front end portion (rear end portion). Note that the arm portion 44 b connected to the engaging portion 441 is in a state of being separated from the restriction surface 262 of the protrusion portion 26.

  In the state where the card 100 moves from the discharge position to the mounting position, as shown in FIG. 11B, the vicinity of the rear end of the arm portion 44c is in contact with the sliding surface 261 by its restoring force. It has become. When the card 100 moves from the ejection position to the mounting position, the lock spring 44 is also moved forward with the movement of the slider 4, so that the vicinity of the rear end portion of the arm portion 44c is separated from the flat portion 264. It moves while making sliding contact with the inclined surface portion 263. FIG. 11B shows a state in which the vicinity of the rear end portion of the arm portion 44 c is in contact with the inclined surface portion 263. Note that the tip of the urging portion 442 is in a state of being separated from the side wall portion 22 on the right side.

  On the other hand, in the arm part 44b of the lock spring 44, the contact part 441b is in contact with the regulation surface 262 of the projection part 26 (or opposed with some clearance therebetween). In the state of the process in which the card 100 is moved from the mounting position to the ejection position, the contact portion 441b abuts against the restriction surface 262 in this way, so that the displacement of the engagement portion 441 in the direction away from the card is restricted. ing. For this reason, in this state, the engagement by the engagement portion 441 with respect to the card 100 can be reliably maintained.

  FIG. 11B shows the state of the process in which the card 100 moves from the ejection position to the mounting position, but the protrusion 26 also shows the state in the process of moving the card 100 from the mounting position to the ejection position. And the lock spring 44 are in the same state. In this case, the vicinity of the rear end portion of the arm portion 44c moves while sliding in contact with the front portion of the sliding surface 261, the inclined surface portion 263, and the flat surface portion 264.

  In the state where the card 100 is disposed at the mounting position, as shown in FIG. 11C, the arm portion 44c is moved to a position on the front side of the connector 1 with respect to the sliding surface 261, and is connected thereto. The urging portion 442 is kept away from the right side wall portion 22. Further, the engaging portion 441 maintains a state in which the abutting portion 441b abuts on the regulation surface 262 (or opposes with some clearance therebetween). Therefore, even in this state, the engagement by the engaging portion 441 with respect to the card 100 can be reliably maintained.

  In a state where the card 100 is pulled out from the ejection position, the hook-shaped portion 441a of the engaging portion 441 is retracted to the right side of the connector 1 as shown in FIG. Thus, in the state where the card 100 is disposed at the ejection position, the contact portion 441b is disposed on the rear side of the restriction surface 262, and the engagement portion 441 is allowed to move away from the card. . In addition, the state of the arm part 44c and the urging | biasing part 442 connected with this maintains the state shown to Fig.11 (a). That is, the vicinity of the rear end portion of the arm portion 44c is in contact with the flat surface portion 264, and the distal end portion of the biasing portion 442 is in contact with the inner wall surface of the right side wall portion 22.

  In the connector 1 having such a configuration, when the card 100 mounted at the mounting position is ejected, the slider 4 is pushed to the rear side of the connector 1 according to the biasing force of the biasing spring 5. Thus, in the process in which the slider 4 is pushed out, the protrusion 26 and the lock spring 44 shift from the state shown in FIG. 11C to the state shown in FIG. In this case, the vicinity of the rear end portion of the arm portion 44c is first in contact with the front portion of the sliding surface 261. As the slide 4 moves in the discharging direction (the rear side of the connector 1), the slide 4 moves while sliding on the inclined surface portion 263 and the flat surface portion 264.

  Since the inclined surface portion 263 of the projecting portion 26 is configured to protrude toward the right side wall portion 22 toward the rear side of the connector 1, an arm portion 44 c (lock spring 44) with respect to the sliding surface 261 is provided. Since the spring moves in the direction in which the accumulated force increases, the urging force gradually increases as the slider 4 moves in the discharge direction. In the connector 1 according to the present embodiment, the arm portion 44c of the lock spring 44 is urged against the sliding surface 261 of the projection portion 26 constituting a part of the housing 2 in this way, so that the slider 4 is restrained. Power can be given.

  As described above, in the connector 1 according to the present embodiment, the projecting portion 26 constituting a part of the housing 2 is provided with the sliding surface 261 that receives the biasing force by sliding the biasing portion 442 of the lock spring 44. Since the sliding surface 261 is shaped to increase the urging force from the urging portion 442 of the lock spring 44 as the slider 4 moves in the discharging direction, the lock spring having the engaging portion 441 with the card 100 is provided. 44 and the protrusion 26 can apply a braking force to the slider 4 as it moves in the ejecting direction, so that the lock spring 44 that prevents the card 100 from coming off can also be used as a braking member. It becomes possible to prevent the card 100 from popping out without requiring a dedicated member.

  Further, in the connector 1 according to the present embodiment, the displacement of the lock spring 44 in the direction in which the engaging portion 441 moves away from the card 100 in the process of moving the card 100 between the mounting position and the discharging position on the protrusion 26. On the other hand, a restricting surface 262 is provided that allows displacement of the lock spring 44 in a direction in which the engaging portion 441 moves away from the card 100 at the ejection position, and the restricting surface 262 is disposed at a position corresponding to the sliding surface 261. is doing. As described above, since the restriction surface 262 that allows or restricts the displacement of the lock spring 44 according to the position of the card 100 is disposed at a position corresponding to the slide surface 261, the contact position of the lock spring 44 with respect to the slide surface 261. Accordingly, the engagement between the lock spring 44 and the card 10 and the release thereof can be linked to each other, so that it is possible to prevent a situation where the engagement between the lock spring 44 and the card 100 is undesirably released. .

  In particular, in the connector 1 according to the present embodiment, the sliding surface 261 and the regulating surface 262 are formed on the protrusion 26 provided on the housing 2, so that the braking function of the slider 4 and the engagement of the card 100 are performed. In addition, since the single member can have the release function, the configuration of the housing 2 can be simplified.

  Further, in the connector 1 according to the present embodiment, since the protruding portion 26 having the sliding surface 261 and the regulating surface 262 is provided in the movement region of the slider 4 of the slider 4, the protruding portion is provided in the connector 1. Since it is not necessary to separately provide a space for arranging the connector 26, the connector 1 can be reduced in size.

  Furthermore, in the connector 1 according to the present embodiment, the lock spring 44 has a U-shape, and the sliding surface 261 and the regulating surface 262 formed on the protrusion 26 are sandwiched. In addition to simplification, the space for accommodating the lock spring 44 can be saved.
