The opening 63 a is hooked, and thereby the shell 61 is fixed to the housing 11. The card connector 1 has a substantially flat rectangular parallelepiped shape, and is attached to the surface of a board such as a printed wiring board provided in the electronic device, for example, rearward (lower left in FIG. 1). The card tray 161 is inserted from the insertion slot 18. Specifically, the card tray 161 is inserted into a card insertion space formed between the housing 11 and the shell 61.

  The housing 11 includes a plurality of terminals 51 and a lower shell 12 that are integrally formed by punching, bending, or the like from a metal plate, and surrounding the terminals 51 and the lower shell 12. It is a substantially flat plate-like member including a resin member made of an insulating resin molded by a molding method called insert molding or overmold molding so as to cover and integrate at least a part of. The lower shell 12 is a frame member that reinforces the housing 11 and is preferably formed from the same member as the terminal 51, but is separated from the terminal 51 and electrically insulated.

  The housing 11 extends in the width direction along a bottom wall portion 11b as a substantially rectangular flat plate-shaped terminal holding portion and a front end portion 11f in the insertion direction (front-rear direction) of the card tray 161 in the housing 11. The rear wall portion 11a is thicker than the bottom wall portion 11b, and the pair of side wall portions 11e extends in the insertion direction along the left and right side edges of the housing 11 and is thicker than the bottom wall portion 11b. The back wall portion 11a and the side wall portion 11e have lower surfaces that are flush with the lower surface of the bottom wall portion 11b, and upper surfaces thereof are located above the upper surface of the bottom wall portion 11b. The end of the housing 11 in the insertion direction of the card tray 161 is referred to as a rear end 11r.

  Here, the bottom wall portion 11 b includes a terminal holding recess 11 c that accommodates and holds the exposed portion of the terminal 51 and a solder tail opening 11 d. The terminal holding recess 11c and the solder tail opening 11d are openings that penetrate the bottom wall portion 11b in the plate thickness direction. The solder tail opening 11d is single, and the solder tail portion 51d as a soldered portion of all the terminals 51 is exposed. The terminal holding recesses 11 c are plural and are arranged side by side so as to form a row extending in the width direction of the housing 11. In the example shown in the figure, they are arranged in two rows of three. That is, the terminal holding recesses 11 c and the terminals 51 held one by one in each terminal holding recess 11 c are arranged to form two rows extending in the width direction of the housing 11.

  Each of the terminals 51 is at least partially embedded in the bottom wall portion 11b, the top portion 51c is exposed in each terminal holding recess 11c, and the solder tail portion 51d is exposed in the solder tail opening 11d. Therefore, the terminals 51 held one by one in each terminal holding recess 11 c are also arranged in two rows extending in the width direction of the housing 11. The top portion 51 c is urged upward by the spring property of the terminal 51 and contacts each of the electrode pads of the card 101 in the card tray 161 held in the card connector 1. Each solder tail portion 51d is in a state of being surely connected to the conductive trace by being soldered to a connection pad (not shown) connected to the conductive trace included in the substrate.

At the front end portion of the push rod 22, an engaging portion 22b that engages with the power point portion 21b of the eject lever 21 is formed. The eject lever 21 is a lever-like member disposed in the vicinity of the back wall portion 11a, and functions as a tray discharge lever member in the tray discharge mechanism. Therefore, the eject lever 21 is attached to the bottom wall portion 11b so as to be pivotable at the fulcrum portion 21c. Then, the end of the eject lever 21 opposite to the force application part 21b across the fulcrum part 21c contacts the front frame part 165 of the card tray 161 inserted into the card connector 1, and the card tray It functions as an action point portion 21 a that applies a force in the discharging direction to 161.

  Further, in the housing 11, the card tray 161 inserted into the card connector 1 is held at a predetermined position in the card connector 1 (the card tray 161 is held by the holding spring member 25 and the card tray 161. The movable member 27 and the fixed member 28 of the detection switch for detecting that the electrode pad of the card 101 accommodated in the card 101 has reached the position 51 in contact with the top 51c of the corresponding terminal 51 are disposed. When the card tray 161 has not reached the predetermined position, since the movable member 27 and the fixed member 28 are separated from each other, the detection switch is in a non-conductive state, that is, turned off. However, when the card tray 161 reaches the predetermined position, the movable member 27 is pressed against the front frame portion 165 of the card tray 161, whereby the movable member 27 is displaced and contacts the fixed member 28. . Therefore, since the detection switch is in a conductive state, that is, turned on (ON), it is detected that the card tray 161 has reached the predetermined position.

  Next, the configuration of the terminal 51 will be described in detail.

  FIG. 3 is a top view of the card connector with the shell removed in the embodiment of the present invention, and FIG. 4 is a partially enlarged view of the terminal in the embodiment of the present invention. 4A is a cross-sectional view taken along the line AA in FIG. 3, and FIG. 4B is a cross-sectional view taken along the line BB in FIG. 3.

  As shown in the figure, in the present embodiment, at least part of the base 51a of the terminal 51 is embedded in the bottom wall 11b, the solder tail 51d is exposed in the solder tail opening 11d, and the others. Is exposed in the terminal holding recess 11c. The base 51a is an elongated strip-like member in plan view, and both longitudinal ends thereof are embedded in the bottom wall portion 11b, and the portion between both ends is exposed in the terminal holding recess 11c.

  The terminal 51 has a base end connected to an intermediate portion of the base 51a, is elastically deformable, and has an arm portion as a spring that functions as a cantilever having a constant plate thickness. 51b. The arm portion 51b is an elongated strip-like member in plan view, and from the base end connected to the base portion 51a, one side wall portion 11e (in the example shown in FIG. 3, the left side wall portion 11e). It extends toward

  Further, the terminal 51 has a front and side shape as shown in FIG. 4 in a state where no external force is applied, that is, in an initial state. Specifically, as shown in FIG. 4B, the arm portion 51b forms a flat surface with the base portion 51a, and a flat plate portion 51b1 extending in parallel with the upper surface of the bottom wall portion 11b. , Connected to the tip of the flat plate portion 51b1, and in a side view, connected to the tip of the curved portion 51b2 and a curved portion 51b2 having a curved shape with the center of curvature positioned upward. The front portion 51b3 is located above the upper surface of the bottom wall portion 11b, and the tip thereof faces obliquely upward. Note that the front portion 51b3 may have a linear shape in a side view, or may include a portion having a curved shape similar to the bending portion 51b2. Further, the base 51a is positioned below the upper surface of the bottom wall 11b, and the arm 51b does not include an inflection point in an initial state and is in a straight line with the base 51a. So that they are connected.

  Furthermore, a guide portion 51e extends from the tip of the arm portion 51b, that is, from the top portion 51c located at the free end, toward both the left and right sides. Specifically, as shown in FIG. 3, the left and right guide portions 51e extend obliquely outward from the tip of the arm portion 51b and rearward in the extending direction of the arm portion 51b (the direction of the base portion 51a). I'm out. For this reason, the combined portion of the arm portion 51b and the left and right guide portions 51e has an arrow-like shape in plan view. As shown in FIG. 4B, each guide portion 51e is connected to a guide upper end portion 51e1 connected to the tip (top portion 51c) of the arm portion 51b, and to the guide upper end portion 51e1. A guide slope extending linearly obliquely outward and rearward from the top 51c and obliquely linearly downward (in the direction of the bottom wall 11b) and obliquely rearward from the top 51c in a side view. A portion 51e2 and a free end of the guide inclined portion 51e2, that is, a guide tip portion 51e3 that is a tip of the guide portion 51e are provided.

  The guide tip 51e3 is located below the top surface of the bottom wall 11b, but below the bottom surface of the bottom wall 11b, both in the initial state and in a state where an external force is applied to the terminal 51. There is nothing. That is, the guide tip 51e3 is always located between the upper surface and the lower surface of the bottom wall portion 11b, and is not located above or below the lower surface of the bottom wall portion 11b. The guide tip 51e3 is always separated from the inner peripheral surface of the terminal holding recess 11c, which is an opening penetrating the bottom wall portion 11b, and does not contact the inner peripheral surface.

  Next, the operation of the terminal 51 will be described.

  FIG. 5 is a first diagram illustrating a change in the contact state between the card connector terminal and the card in the embodiment of the present invention, and FIG. 6 is a diagram illustrating the relationship between the card connector terminal and the card in the embodiment of the present invention. It is a 2nd figure explaining the change of a contact state. 5, (a) to (d) are cross-sectional views taken along line AA in FIG. 3 at each stage. In FIG. 6, (a) to (d) are FIG. 3 at each stage. It is BB arrow sectional drawing.

  The user inserts the card tray 161 containing the card 101 as the card module 102 into the insertion slot 18 from the back of the card connector 1 with fingers or the like. Here, the card tray 161 is inserted in such a posture that the front frame portion 165 faces the front end portion 11f of the housing 11, and the card 101 accommodated in the card accommodating recess 166 is provided with an electrode pad. In this state, the exposed surface is exposed to the lower surface of the card tray 161 and faces downward. The card tray 161 can be inserted into and ejected from the card connector 1 regardless of whether the card 101 is accommodated or the card 101 is accommodated. Only the case where 101 is accommodated will be described.

  When the user inserts the card tray 161 into the insertion slot 18 and further proceeds, the card tray 161 moves through the front end portion 11f in the card insertion space formed between the shell 61 and the housing 11. It proceeds toward and reaches a predetermined position. At this time, more specifically, each terminal 51 comes into contact with the card 101 and is gradually elastically deformed as shown in FIGS. 5 and 6, for convenience of explanation, the card tray 161 is omitted, and only the card 101 is depicted. 5A to 5D are depicted such that the insertion direction of the card 101 is the left direction.

  First, as shown in FIGS. 5 (a) and 6 (a), the lower end of the front end 111f of the card 101 reaches the terminal holding recess 11c, and then in FIGS. 5 (b) and 6 (b). As shown, the lower end of the front end 111f of the card 101 abuts on the guide inclined portion 51e2 in the guide portion 51e on one side (the rear end portion 11r side) of the terminal 51. As described above, since the guide tip 51e3 is always located below the upper surface of the bottom wall 11b, the lower end of the front end 111f of the card 101 is always in contact with the guide inclined portion 51e2.

  Subsequently, when the card 101 advances toward the front end portion 11f, the lower end of the front end 111f of the card 101 advances while maintaining contact with the guide inclined portion 51e2 in the guide portion 51e on the rear end portion 11r side, Since it slides on the guide inclined part 51e2, the front part 51b3 of the arm part 51b is pushed downward together with the guide part 51e, as shown in FIGS. 5C and 6C. Displaces elastically downward.

  Subsequently, when the card 101 further proceeds toward the front end portion 11f, the lower end of the front end 111f of the card 101 passes through the top portion 51c as shown in FIGS. 5 (d) and 6 (d). Slides on the surface of the card 101 facing downward. The front part 51b3 and the guide part 51e in the arm part 51b are not displaced downward any more. As shown in FIG. 5D and FIG. 6D, even when the front portion 51b3 is displaced downward by the inserted card 101, all of the arm portion 51b and the guide portion 51e The portion is positioned above the lower surface of the bottom wall portion 11b and does not protrude downward from the lower surface. Therefore, even if the lower surface is in contact with the upper surface of the substrate, the terminals 51 do not come into contact with the conductive traces exposed on the upper surface of the substrate, and a short circuit does not occur.

  Next, a modified example of the terminal 51 will be described.

  FIG. 7 is a diagram showing first and second examples of terminals of the card connector according to the embodiment of the present invention. In the drawings, (a-1) to (a-3) and (b-1) to (b-3) are a partial top view, a partial front view, and a partial side view of the first and second examples. .

  As shown in FIGS. 7A-1 and 7B-1, in the plan view, in the terminal 51 of the first example, the guide part 51e is formed shorter than the arm part 51b, and the second example of FIG. In the terminal 51, the guide part 51e is formed longer than the arm part 51b. In addition, the length of the arm part 51b is equal in the terminal 51 of the 1st and 2nd examples.

  However, as shown in FIGS. 7 (a-2), (a-3), (b-2), and (b-3), in the terminal 51 of the first and second examples, the guide tip 51e3 is It is always located between the upper surface and the lower surface of the bottom wall portion 11b. That is, in the terminal 51 in the present embodiment, the guide tip 51e3 is always positioned between the upper surface and the lower surface of the bottom wall portion 11b regardless of the length of the guide portion 51e, and the upper surface of the bottom wall portion 11b. It is formed so as not to be positioned above or below the lower surface.

  Thus, in the present embodiment, the card module 102 having the electrode pads on one side is inserted into the card connector 1. The card connector 1 includes a housing 11 including a bottom wall portion 11b in which terminals 51 that contact the electrode pads of the card module 102 are disposed. The terminal 51 includes a base portion 51a held by the bottom wall portion 11b. From the both sides of the cantilever-like arm portion 51b extending laterally with respect to the insertion direction of the card module 102 and the top portion 51c located at the free end of the arm portion 51b in plan view from the base portion 51a, A pair of guide portions 51e extending obliquely rearward with respect to the extending direction of the arm portion 51b, and a guide tip portion 51e3 which is a free end of each guide portion 51e is below the upper surface of the bottom wall portion 11b and on the lower surface Located above.

  As a result, even if there are protrusions and corners on one surface of the card module 102, the protrusions and corners abut against the guide portion 51e when the card module 102 is inserted and ejected. Since it slides on the guide part 51e, it does not catch on the arm part 51b or the guide tip part 51e3. Therefore, the card module 102 can be smoothly inserted and ejected, and the terminal 51 is not damaged or plastically deformed. Therefore, the card connector 1 is highly reliable. In particular, when the card module 102 is a card tray 161 that accommodates the card 101, an empty card tray 161 that does not accommodate the card 101 may be inserted into the card connector 1. When such an empty card tray 161 is inserted and ejected, there is a possibility that the front frame portion 165 and the like of the card tray 161 may come into contact with the terminals 51. Since the part 165 and the like abut against the guide part 51e and slide on the guide part 51e, the arm part 51b and the guide tip part 51e3 are not caught.

  Further, one of the pair of guide portions 51e is inclined so as to approach the front in the insertion direction of the card module 102 in plan view, and the other of the pair of guide portions 51e is in top view 51c in plan view. The closer it is, the closer it is to the rear of the card module 102 in the insertion direction. Therefore, when the card module 102 is inserted or ejected, the protrusions and corners of the card module 102 can smoothly slide on the guide part 51e, and the arm part 51b and the guide tip part 51e3. It is not caught in.

  Further, the arm portion 51b is connected to the curved portion 51b2 having a curved surface with the center of curvature positioned upward in a side view, the distal end of the curved portion 51b2, the top portion 51c, and the bottom wall portion 11b. Each guide part 51e is inclined with respect to the guide upper end part 51e1 connected to the top part 51c and the front part 51b3 of the arm part 51b, and the guide upper end part 51e1. The guide inclined portion 51e2 is connected to the guide tip portion 51e3, and the guide inclined portion 51e2 includes a portion located above the upper surface of the bottom wall portion 11b. As a result, the top portion 51c comes into contact with the electrode pad of the card module 102. Therefore, when the card module 102 is inserted and ejected, the wiping effect on the surface of the electrode pad by the top portion 51c can be expected. Further, since the inserted card module 102 is surely brought into contact with the guide inclined portion 51e2, the card module 102 slides on the guide inclined portion 51e2 and is not caught by the arm portion 51b or the guide tip portion 51e3.

  Further, in plan view, the base 51a is a strip-like member extending in the insertion direction of the card module 102, and the arm 51b is a strip extending laterally from the base 51a in the insertion direction of the card module 102. Each guide portion 51e is a strip-like member extending obliquely rearward with respect to the extending direction of the arm portion 51b from the top portion 51c. Thus, since the structure of the arm part 51b which functions as a spring part is simple, strength adjustment of a spring part becomes easy.

  Furthermore, even if the top 51c is displaced downward, the guide tip 51e3 is positioned below the upper surface and above the lower surface of the bottom wall 11b. Therefore, the card module 102 is not caught by the guide tip 51e3, and even if the lower surface of the bottom wall portion 11b is in contact with the upper surface of the substrate, the conductive trace in which the terminal 51 is exposed on the upper surface of the substrate, etc. The short circuit does not occur.

  In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.

  The present invention can be applied to a card connector.
