Description

  The present invention relates to a terminal unit and a card connector.

  Conventionally, in electronic devices such as personal computers, mobile phones, PDAs (Personal Digital Assistants), digital cameras, video cameras, music players, game consoles, vehicle navigation devices, SIM (Subscriber Identity Module) cards, MMC (R) (Multi Media Card), SD (R) (Secure Digital) card, miniSD (R) card, xD Picture Card (R) (xD-Picture Card), Memory Stick (R), Memory Stick Duo (R), SmartMedia In order to use various cards such as (R), Trans-Flash (R) memory card, micro SD (R) card, etc., a card connector is provided ( For example, see Patent Document 1.)

  FIG. 7 shows a conventional card connector.

  In the figure, reference numeral 811 denotes a card connector housing made of an insulating resin material, which accommodates the inserted card 961 therein. The card 961 is, for example, a micro SD® card, and includes a plurality of electrode pads 951 exposed on the lower surface.

  A plurality of terminals 851 are arranged in the housing 811 so as to match the arrangement of the electrode pads 951. Each terminal 851 is a cantilever (beam) -like member whose base end is fixed to the back wall portion 811a of the housing 811. The tip, that is, the free end is a sliding motion portion 851b. ing. The sliding portion 851b is slidably held on the bottom wall portion 811b of the housing 811. Each terminal 851 includes a mountain-shaped contact portion 851a formed between the base end and the sliding portion 851b. The contact portion 851 a contacts the electrode pad 951 of the card 961 inserted into the housing 811.

  In the figure, 811c is a central horizontal beam of the housing 811 and 811d is a front horizontal beam of the housing 811. Further, a flat cover member (not shown) is attached above the housing 811, and the card 961 is inserted and held in a card accommodation space formed between the housing 811 and the cover member.

  When the card 961 is inserted into the card accommodation space whose upper surface is determined by the cover member, the contact portion 851a of the terminal 851 is pressed from above by the electrode pad 951 of the card 961 and displaced downward. Then, the sliding portion 851b slides on the bottom wall portion 811b of the housing 811 and is displaced forward. The terminal 851 is elastically deformed in this manner to exert a spring force, and the contact portion 851a is pressed against the electrode pad 951 of the card 961 by the spring force. Accordingly, even if the thickness of the card 961 varies and the vertical position of the electrode pad 951 changes, the contact portion 851a follows the change in the vertical position of the electrode pad 951. Thus, contact with the electrode pad 951 can be reliably maintained.

JP 2009-129890 A

  However, in the conventional card connector, since the terminal 851 is in a cantilever shape with one end, that is, the base end fixed, if the displacement amount of the contact portion 851a in the vertical direction is increased, the base end It is necessary to increase the distance from the contact portion 851a to the contact portion 851a. For this reason, the entire length of the terminal 851 is increased, and as a result, the card connector is increased in size. Further, when the total length of the terminal 851 is shortened, the amount of displacement of the contact portion 851a in the vertical direction is reduced. Therefore, when there is variation in the thickness direction of the card 961, the contact with the electrode pad 951 is reliably maintained. It becomes difficult to do.

  The present invention solves the above-described conventional problems, and supports both ends of the contact member separate from the support member from below, thereby reducing the overall length and reducing the amount of elastic displacement in the vertical direction. It is an object of the present invention to provide a terminal unit that can be enlarged and can reliably maintain a contact state with a counterpart terminal and a card connector including the terminal unit.

  Therefore, in the terminal unit of the present invention, a support member including an elongated flat plate-like support body portion, an elastic elongated plate-like contact body portion, and a bent top portion formed at the longitudinal center of the contact body portion And a contact member including a pair of supported parts connected to both ends in the longitudinal direction of the contact main body part, the support member and the contact member are separate members, and the pair of supported parts are It is supported from below without being fixed by the support main body, and the bent top projects upward.

  In another terminal unit of the present invention, the pair of supported portions can slide on the support main body.

  In still another terminal unit of the present invention, the contact main body has a maximum width dimension at the center in the longitudinal direction, and the width dimension gradually decreases toward both ends in the longitudinal direction.

  In still another terminal unit of the present invention, the distance from the support main body portion to the contact main body portion is the maximum at the bent top portion, and gradually decreases toward both ends in the longitudinal direction of the contact main body portion.

  In still another terminal unit of the present invention, the bent tops can be elastically displaced in the vertical direction, and the distance between the supported parts expands and contracts when the bent tops are displaced in the vertical direction.

  In still another terminal unit of the present invention, the contact member further includes an engagement portion extending from each supported portion in the width direction of the contact main body portion, and the engagement portion includes the support member. It is possible to engage with a holding engagement portion formed on the holding member to be held.

  In still another terminal unit of the present invention, the holding engagement portion further includes eaves portions extending toward both longitudinal ends of the support body portion, and no external force is applied to the contact member. The engaging portion is located in a recessed portion between the flange portion and the support main body portion, thereby preventing the contact member and the support member from being separated.

  The card connector of the present invention is a card connector into which a card module having electrode pads on one surface is inserted, and a housing including a holding member in which a terminal unit that contacts the electrode pads of the card module is disposed. And the terminal unit is the terminal unit of the present invention.

  In another card connector according to the present invention, the contact main body of the terminal unit extends in the insertion and ejection directions of the card module.

  According to the present invention, the contact member separate from the support member is supported from below without being fixed at both ends. Thereby, while shortening the full length of a terminal unit, the elastic displacement amount of an up-down direction can be enlarged, and a contact state with an other party terminal can be maintained reliably.

  In the figure, reference numeral 102 denotes a card module according to the present embodiment, which is inserted into a card connector 1 attached to an electronic device (not shown). That is, the card module 102 is attached to the electronic device via the card connector 1. The electronic device is, for example, a personal computer, a tablet computer, a smartphone, a mobile phone, a communication modem, a PDA, a digital camera, a video camera, a music player, a game machine, a vehicle navigation device, etc. It may be.

  The card module 102 includes, for example, a SIM card, a micro SIM (micro SIM) card, a nano SIM (nano SIM) card, an MMC (R), an SD (R) card, a miniSD (R) card, an xD picture card (R), a memory, and the like. It may be a memory card itself such as a stick (R), a memory stick Duo (R), a smart media (R), or a Trans-Flash (R) memory card. Also, for example, a card having a shape and dimensions suitable for insertion into the card connector 1, such as an SD (R) card type adapter that accommodates a miniSD (R) card, and that accommodates a memory card therein. Adapter may be used. Further, it may be a card tray having a shape and size suitable for insertion into the card connector 1 and containing a memory card therein. In short, the card module 102 may be any type of module as long as it can be inserted into the card connector 1 and can be electrically connected to the electronic device via the card connector 1.

  In the present embodiment, for convenience of explanation, a case will be described in which the card module 102 is a card tray 161 as a card holding member that houses the card 101 as shown in FIG. The card 101 will be described as a 4FF (4th Form Factor) card, a so-called nano SIM card. According to ETSI TS 102 221 V11.00, which is a card standard, the size of the nano SIM card is 12.3 [mm] in the front and rear, 8.8 [mm] in width, and 0.67 [mm] in thickness. It is prescribed.

  As shown in FIG. 1, the card 101 has a generally rectangular plate shape as a whole, and a plurality of electrode pads (not shown) as terminal members are formed on the lower surface of the front end 111f. For example, three are arranged in two rows so as to be aligned along the left and right side ends 111s connecting both ends and both ends of the rear end 111r. That is, the electrode pads are arranged so as to form two rows extending in the front-rear direction of the card 101. In addition, the electrode pad is not arrange | positioned in the surface on the opposite side to a lower surface, ie, the upper surface 111b. Further, a cutout portion 111c as an inclined portion cut out obliquely is formed at one of the corners connecting the left and right ends of the front end 111f and the side end 111s.

  In the present embodiment, the upper, lower, left, right, front, rear, etc. are used to describe the configuration and operation of each part of the card connector 1, the card module 102, the card tray 161, and the card 101. The expression indicating the direction of the card is relative rather than absolute, and when the card connector 1, the card module 102, the card tray 161, the card 101 or their components are in the posture shown in the figure. Although appropriate, when the attitude of the card connector 1, the card module 102, the card tray 161, the card 101, or their components changes, it should be interpreted according to the change in attitude. .

  Here, the card tray 161 is an integrally formed member made of conductive metal or insulating resin, and surrounds four sides of the space portion 166 as a card storage space for storing the card 101 ( A substantially rectangular frame member 167 is provided. The frame member 167 includes a rear frame portion 162 and a front frame portion 165 that extend in the width direction and are parallel to each other, and extend in the front-rear direction, and both ends of the rear frame portion 162 and both ends of the front frame portion 165 are connected. A pair of left and right side frame portions 164 to be connected is included. A rear plate portion 163 is integrally formed on the rear surface of the rear frame portion 162.

  The space portion 166 is a substantially rectangular space that penetrates the card tray 161 from its upper surface to its lower surface, and its four sides are defined by the rear frame portion 162, the front frame portion 165, and the side frame portion 164. A side surface 112 (a surface extending in a direction orthogonal to the lower surface and the upper surface 111b and connecting the lower surface and the upper surface 111b) of the card 101 accommodated in the space portion 166 is a rear frame portion 162 and a front frame portion 165. The frame member 167 is surrounded by the frame member 167 so as to face the inner side surface of the side frame portion 164.

  Further, an inclined portion 167c is formed at a corner portion connected to one side frame portion 164 in the front frame portion 165, specifically, at a front right corner portion. The inclined portion 167c functions as a card posture restricting portion, and allows the card 101 to be accommodated in the card tray 161 when the card 101 is in a normal posture as shown in FIG. When the card 101 is in an irregular posture, the card 101 is not allowed to be accommodated in the card tray 161, that is, the card 101 cannot be accommodated in the space portion 166. Specifically, the inclined portion 167c is formed so as to face the cutout portion 111c of the card 101 accommodated in the space portion 166 in a normal posture. Therefore, the card 101 having an irregular posture, for example, a posture such as upside down and upside down cannot be accommodated in the space portion 166 of the card tray 161.

  The rear frame portion 162, the side frame portion 164, and the front frame portion 165 are formed such that the top surfaces thereof are flush with each other and the thickness of the card tray 161 is equal. Then, from the inner lower ends of the rear frame portion 162 and the left and right side frame portions 164, a hook-like card support portion (not shown) extends toward the inner side of the space portion 166. The card support part supports at least a part of the lower surface of the card 101 accommodated in the space part 166, for example, the vicinity of the side end. Note that the protruding amount of the card support portion is small and does not interfere with the electrode pads disposed on the lower surface of the card 101. That is, the space 166 is set to a size that does not interfere with at least the electrode pad of the card 101 on the lower surface of the card tray 161.

  In front view, the left and right side frame portions 164 protrude downward from the front frame portion 165 at both ends of the front frame portion 165. That is, the card tray 161 has a substantially crown-like shape when viewed from the front. The crown-shaped shape exhibits a function of preventing the card tray 161 from being inserted into the card connector 1 in an upside down orientation, that is, preventing erroneous insertion. Further, it is desirable that the lower surface of the front frame portion 165 is positioned above the lower surface of the card 101 accommodated and held in the space portion 166. This prevents the front frame portion 165 from coming into contact with the terminal unit 50 when the card tray 161 is inserted into the card connector 1.

  Further, a holding recess 168 for holding the card tray 161 in the card connector 1 is formed near the front end on the outer surface of the left and right side frame portions 164, that is, near the front frame portion 165. ing.

  The card tray 161 has a structure in which the card 101 is accommodated in a space portion 166 that penetrates from the upper surface to the lower surface, surrounds the side surface 112 of the card 101, and does not cover both the lower surface and the upper surface 111b. Therefore, the dimension in the thickness direction can be reduced. Therefore, the card connector 1 can be reduced in height. Moreover, when it consists of a metal, sufficient intensity | strength can be maintained even if the dimension of the front-back direction and the width direction is made small. Therefore, the card connector 1 can be reduced in size.

  In the present embodiment, the card connector 1 is integrally formed of an insulating material such as a resin, and is punched and bent into a housing 11 that houses the card connector 1 and a plate made of a conductive metal. And a shell 61 as a cover member that is integrally formed by the above processing and attached to the upper side of the housing 11. The shell 61 covers the upper part of at least a part of the card tray 161 inserted into the housing 11 and the card connector 1. The card connector 1 has a generally flat and rectangular parallelepiped shape, is attached to the electronic device, and is inserted into the housing 11 from the insertion port 18 at the rear (lower left in FIG. 1) to the card tray 161. Is inserted. Specifically, the card tray 161 is inserted into an insertion space formed between the housing 11 and the shell 61.

  As shown in FIG. 2, the housing 11 is formed along the bottom wall portion 11b, which is a substantially rectangular flat plate-like member, and the front end portion in the insertion direction of the card tray 161 in the housing 11, that is, the front end portion 11f. It has the back wall part 11a extended and standing from the bottom wall part 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 part 11b is provided with the terminal accommodation recessed part 16 which accommodates the terminal unit 50 as a connection terminal. The terminal receiving recesses 16 are openings that penetrate the bottom wall portion 11b in the plate thickness direction, and are arranged in a staggered manner so as to form a bent row extending in the front-rear direction of the housing 11. In the example shown in the figure, three are arranged so as to be bent in two rows. That is, the terminal accommodating recesses 16 and the terminal units 50 held one by one in each terminal accommodating recess 16 are arranged in two rows extending in the front-rear direction of the housing 11.

  As shown in FIG. 3, each terminal unit 50 includes a support member 51 and a contact member 52 that are separate from each other. The support member 51 is a plate-like member that is integrally formed of a conductive material such as metal that is at least partially embedded and fixed in the bottom wall portion 11b. In the present embodiment, the bottom wall portion 11 b functions as a holding member that holds the support member 51.

  The support member 51 has a substantially rectangular and long flat plate-like support main body 51a, a pair of support parts 51b positioned at both ends in the longitudinal direction of the support main body 51a, and a middle in the longitudinal direction of the support main body 51a. A connecting portion 51c extending in the lateral direction of the support body 51a from one side edge, that is, the width direction, a solder tail portion 51d as a substrate connecting portion formed at the tip of the connecting portion 51c, and the connection It includes a pair of auxiliary fixing portions 51e extending from the middle of the portion 51c in the longitudinal direction of the support main body portion 51a. In the example shown in FIG. 3, the support portion 51 b is formed to have a smaller width dimension than other portions of the support main body portion 51 a, but the same width as the other portions of the support main body portion 51 a. Dimensions may be provided.

  The support main body 51a including the support 51b is dimensioned in the longitudinal direction so as to block the bottom of the terminal receiving recess 16 over the entire longitudinal range of the terminal receiving recess 16. Is set. The width dimension of the support main body 51a may be large enough to block the entire bottom of the terminal receiving recess 16, but may be large enough to block only a part of the bottom. Further, the auxiliary fixing portion 51e is a portion that is firmly fixed by the bottom wall portion 11b, and the shape and size thereof can be changed as appropriate, and can be omitted if unnecessary. Further, the solder tail portion 51d may be formed at the tip of the support portion 51b by extending one support portion 51b of the pair of support portions 51b.

  On the other hand, the contact member 52 is a member separate from the support member 51, and is a plate-like member having elasticity integrally formed from a conductive material such as metal. The contact member 52 includes an elongated strip-shaped contact main body 52a, a pair of supported portions 52c connected to both ends in the longitudinal direction of the contact main body 52a, and a short portion of the contact main body 52a from each supported portion 52c. The engaging part 52d extended in the hand direction, ie, the width direction, is included. The contact main body portion 52a includes a bent top portion that protrudes upward and is formed at the center in the longitudinal direction so as to have a U-shape in a side view, and is bent in the thickness direction at the bent top portion. It is a part that functions as a spring part. The bent top portion functions as a contact portion 52 b that contacts the electrode pad of the card 101. In addition, as shown in FIG. 4B, it is desirable that the contact portion 52b that is the bent top portion has a curved shape that is gently curved as shown in FIG.

  The contact member 52 is preferably made of, for example, a metal plate that is thinner and more rigid than the members constituting the support member 51 so that the contact main body 52a can exhibit its function as a spring. . The supported portions 52c at both ends of the contact main body 52a are supported from below without being fixed by the support member 51, that is, supported from below by the support member 51 in a floating state. Accordingly, the contact member 52 can be elastically deformed like a simple support beam on both ends in a state of being supported from below without being fixed at both ends, and is elastic in the vertical direction of the contact portion 52b which is a bent top portion. The displacement is large. When the contact part 52b is displaced in the vertical direction, the distance between the supported parts 52c expands and contracts.

  Further, the contact main body 52a may be a rectangular member having a constant width dimension in a plan view, but as shown clearly in FIGS. That is, it is desirable that the width dimension is the maximum at the position of the contact portion 52b, and the taper shape is such that the width dimension gradually decreases toward both ends in the longitudinal direction. Thereby, the property approximated to the beam of equal strength whose bending stress is uniform along the length can be obtained.

  The terminal receiving recess 16 includes an elongated strip-shaped central recess 16a corresponding to the contact main body 52a of the contact member 52, a pair of wide recesses 16b connected to both longitudinal ends of the central recess 16a, and the central recess 16a. It includes a narrowed narrowing portion 16c located between the wide concave portion 16b. In addition, the circumference | surroundings of each aperture | diaphragm | squeeze part 16c are demarcated by the protrusion engaging part 15 as a pair of holding | maintenance engaging part from which a part of bottom wall part 11b which demarcates the periphery of the terminal accommodating recessed part 16 protrudes.

  And the said center recessed part 16a is formed so that a width dimension may become larger than the contact main-body part 52a of the contact member 52, and, thereby, the said contact main-body part 52a can be accommodated. Further, as shown in FIG. 2, the central recess 16a may have a rectangular shape with a constant width dimension in plan view, but as shown in FIGS. 4 (a) and 4 (c). In addition, the shape in plan view may be a tapered shape in which the width dimension is maximum at the center in the longitudinal direction and the width dimension gradually decreases toward both ends in the longitudinal direction.

  The wide recessed portion 16b is formed so that the width dimension is larger than the engaging portion 52d of the contact member 52 and the dimension in the longitudinal direction of the terminal accommodating recessed portion 16 is also larger than the engaging portion 52d. The engaging portion 52d can be accommodated. Further, the narrowed portion 16c is formed so that the width dimension is larger than the supported portion 52c of the contact member 52 but smaller than the engaging portion 52d, and thereby the engagement accommodated in the wide recessed portion 16b. The portion 52d is prevented from being displaced toward the longitudinal center and moving into the central recess 16a.

  Further, as shown in FIGS. 4B and 4D, in the cross-sectional view, the projecting engagement portion 15 includes a flange portion 15a extending from the throttle portion 16c toward the wide recess portion 16b. Accordingly, a recessed portion 16d that is recessed toward the longitudinal center of the terminal accommodating recessed portion 16 is formed in the wide recessed portion 16b below the flange portion 15a and between the supporting main body portion 51a. When the engaging part 52d accommodated in the wide recessed part 16b is located in the recessed part 16d, the upward displacement of the engaging part 52d is prevented, so that the contact member 52 is connected to the terminal accommodating recessed part 16d. As a result, the contact member 52 and the support member 51 are prevented from being separated.

  In the state before the card tray 161 is inserted into the insertion space formed between the housing 11 and the shell 61, that is, in the initial state where no external force is applied to the contact member 52, the contact member 52 is shown in FIG. As shown in b), the contact main body portion 52a has a U-shape, and the contact portion 52b protrudes so as to be positioned above the upper surface of the bottom wall portion 11b. As shown in FIG. 2, the contact member 52 is disposed such that the longitudinal direction thereof coincides with the insertion direction of the card tray 161 in the housing 11. Centering on the part 52b, it is a continuous inclined surface that gently falls toward both the front and rear sides in the insertion direction of the card tray 161. Therefore, when the card tray 161 is inserted and ejected, the lower surface of the card tray 161 and / or the card 101 is not caught by the contact main body portion 52a projecting upward from the upper surface of the bottom wall portion 11b. Can be moved to.

  In the initial state, the supported portion 52 c is slidably in contact with the upper surface of the support main body portion 51 a including the support portion 51 b of the support member 51. The support main body 51a of the support member 51 closes the bottom of the terminal receiving recess 16 at least over the entire range in the longitudinal direction. Further, since the engaging portions 52d at both ends in the longitudinal direction are located in the recessed portion 16d in the wide recessed portion 16b, the contact member 52 does not separate from the terminal accommodating recessed portion 16. Furthermore, in the initial state, the distance from the support main body 51a to the contact main body 52a is the maximum at the contact 52b, and gradually decreases toward the both ends in the longitudinal direction of the contact main body 52a.

  In the state where the card tray 161 is inserted into the insertion space formed between the housing 11 and the shell 61, that is, in the use state, the contact member 52 is as shown in FIG. The contact portion 52b is pushed downward by the electrode pad on the lower surface of the card 101 accommodated in the card tray 161, and the contact main body portion 52a is elastically deformed. As a result, the supported portion 52c is slid toward the outside in the longitudinal direction along the upper surface of the support main body portion 51a of the support member 51. In this state, the engaging portion 52d is positioned outside the recessed portion 16d in the wide recessed portion 16b. However, since the contact portion 52b is pushed downward by the card 101, the contact member 52 is There is no detachment from the housing recess 16.

  In use, the supported portion 52c is in contact with the upper surface of the supporting main body 51a including the supporting portion 51b over the wide range in the longitudinal direction. That is, the supported portion 52c is in surface contact with the upper surface of the support main body portion 51a. Therefore, the contact resistance between the supported portion 52c and the upper surface of the support main body portion 51a is smaller than the state in which only the tip of the supported portion 52c is in contact with the upper surface of the support portion 51b as shown in FIG. Since the supported portion 52c is pressed against the upper surface of the support main body 51a by the electrode pad on the lower surface of the card 101, the conductive state between the contact member 52 and the support member 51 is good. Further, since the contact portion 52b is pressed against the electrode pad on the lower surface of the card 101 by the spring force exerted by the contact main body portion 52a, the conduction state between the contact member 52 and the electrode pad on the lower surface of the card 101 is good. Become.

  As described above, the electrode pads of the card 101 are arranged in three rows along the left and right side ends 111 s so that the terminal receiving recesses 16 are arranged in front and rear of the housing 11. In the direction, three are arranged so as to be bent in two rows. Accordingly, the contact portions 52b that come into contact with the electrode pads are arranged in a staggered manner in each row, and are arranged so as to be shifted from each other with respect to the width direction of the electrode pads (the longitudinal direction of the front end 111f and the rear end 111r of the card 101). However, since the magnitude of the shift is smaller than the dimension in the width direction of the electrode pad, each contact portion 52b reliably contacts the corresponding electrode pad.

  The terminal unit 50 is arranged so that the contact portion 52 b of the contact member 52 contacts each of the electrode pads of the card 101 in the card tray 161 held in the card connector 1. Therefore, the number and arrangement form of the terminal units 50 are appropriately changed so as to match the number and arrangement form of the electrode pads of the card 101.

  The bottom wall portion 11b is formed with a solder tail opening 11d that penetrates the bottom wall portion 11b in the thickness direction. And the solder tail part 51d as a board | substrate connection part of all the terminal units 50 is exposed to 11d of this solder tail opening. Each of the solder tail portions 51d is embedded in the bottom wall portion 11b and connected to the support main body portion 51a of the support member 51 of each terminal unit 50 via the connection portion 51c. The solder tail portion 51d is electrically connected to a signal line, a contact pad, a terminal, or the like formed on a wiring board or the like in the electronic device, that is, a counterpart terminal member by soldering or the like.

  And the housing 11 has a pair of side wall part 11e extended in the front-back direction along a side edge, and the tray discharge rod accommodating part 11g is formed inside one side wall part 11e. A push rod 22 as a discharge operation member in a discharge mechanism for discharging the card tray 161 inserted in the card connector 1 is slidably attached to the tray discharge rod accommodating portion 11g in the front-rear direction. . Thereby, the push rod 22 can slide in the front-rear direction along the one side wall portion 11e.

  The push rod 22 is a substantially linear rod-like or strip-like member, and a bent operation portion 22 a is integrally connected to a rear end portion protruding from the housing 11. The operation unit 22a has a shape that facilitates operation when the user of the card connector 1 operates with fingers or the like or through auxiliary members such as pins, needles, and bars.

  Further, an engaging portion 22 b that engages with the power point portion 21 b of the eject lever 21 is formed at the front end portion of the push rod 22. 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 abuts on the card tray 161 inserted into the card connector 1 and is ejected to the card tray 161. It functions as the action point portion 21a for applying the force.

  Further, a holding member 85 as a holding spring portion for holding the card tray 161 inserted into the card connector 1 is housed in the tray discharge rod housing portion 11g. A similar holding member 85 is also housed inside the side wall portion 11e opposite to the tray discharge rod housing portion 11g. Each of these holding members 85 is a band plate-like member made of a metal plate or the like and having a spring property, and its base end is fixed to the housing 11, and its distal end, that is, a free end is in the width direction of the housing 11. It is a cantilever-like member that can be elastically displaced. The holding member 85 is disposed in such a posture that the free end faces the front end portion 11f and the free end is positioned on the inner side in the width direction of the housing 11 than the base end. A holding convex portion 85a that bulges toward the inner side in the width direction of the housing 11 is formed in the vicinity. The holding convex portion 85 a engages with a holding concave portion 168 formed in the side frame portion 164 of the card tray 161.

  The shell 61 includes a substantially rectangular top plate portion 62 and a side plate portion 63 erected from the side edge of the top plate portion 62. The side plate portion 63 is formed with a plurality of latching openings 63a. When the shell 61 is attached to the upper side of the housing 11, the latching projection 13 formed on the outer surface of the side wall portion 11e of the housing 11 The opening 63 a is hooked, and thereby the shell 61 is fixed to the housing 11. In addition, a solder tail portion 64 is formed at an arbitrary position at the lower end of the side plate portion 63 as a board connecting portion standing from the side plate portion 63 and extending outward in the width direction of the shell 61. The solder tail portion 64 is fixed to a fixing pad or the like formed on the surface of a wiring board or the like in the electronic device by soldering or the like. Since at least one of the fixing pads or the like is connected to a ground line provided in the wiring board or the like, the shell 61 is grounded. The front and rear ends of the shell 61 in the insertion direction of the card tray 161 are referred to as a front end portion 61f and a rear end portion 61r.

  The card connector 1 has a detection switch terminal for detecting the card tray 161 inserted into the card connector 1. Specifically, in the vicinity of the front end portion 11 f of the housing 11, the card tray 161 is held at a predetermined position of the card connector 1 (the card tray 161 is held by the holding member 85, and the card tray 161 is The terminal of the tray detection switch is provided as a detection switch for detecting that each electrode pad is inserted to the contact portion 52b of the corresponding terminal unit 50 when the 101 is accommodated. Has been. The tray detection switch includes a first contact member 57 as a cantilever-like terminal attached in the vicinity of the front end portion 11f and the vicinity thereof, and a second terminal as a terminal held in a switch holding recess 11j formed in the bottom wall portion 11b. The contact member 58 is formed. The switch holding recess 11j is an opening penetrating the bottom wall portion 11b in the plate thickness direction.

  In a state where the card tray 161 is not inserted, as shown in FIG. 2, the first contact member 57 is in contact with the second contact member 58, that is, the terminals are in contact with each other, The card detection switch is in a conductive state, that is, turned on. However, when the card tray 161 is inserted into the card connector 1 and reaches a predetermined position, the first contact member 57 is pushed and displaced toward the front end portion 11f by the front frame portion 165 of the card tray 161. The first contact member 57 is separated from the second contact member 58. Accordingly, the first contact member 57 and the second contact member 58 are not in contact with each other, that is, the terminals are not in contact with each other, and the card detection switch is in a non-conduction state, that is, off (OFF). It is detected that 161 has reached a predetermined position of the card connector 1.

  Moreover, the housing 11 includes a flange portion 11h that extends outward in the width direction from the left and right sides of the bottom wall portion 11b. The flange portion 11h is a plate member that is thinner than the bottom wall portion 11b, and is formed so that the lower surface thereof is flush with the lower surface of the bottom wall portion 11b. Therefore, the upper surface of the flange portion 11h is positioned below the upper surface of the bottom wall portion 11b, and as a result, the insertion port 18 formed between the rear end portion 11r of the housing 11 and the rear end portion 61r of the shell 61. The shape is not an elongated rectangular parallelepiped shape having a constant thickness in the entire width direction, but a substantially crown shape protruding downward at both ends.

  As described above, since the front frame portion 165 of the card tray 161 has a substantially crown-like shape in front view and has protrusions at both ends, the insertion slot 18 has the front frame portion. In cooperation with 165, the card tray 161 is inserted into the card connector 1 in an upside-down orientation, that is, it functions to prevent erroneous insertion.

  Further, the dimension in the thickness direction of the portion other than the protruding portion of the insertion port 18 is formed to be smaller than the dimension in the thickness direction of the rear plate portion 163 in the card tray 161. Furthermore, the width direction dimension of the insertion slot 18 is formed smaller than the width direction dimension of the rear plate portion 163 in the card tray 161. Therefore, the insertion port 18 functions in cooperation with the rear plate portion 163 to prevent the card tray 161 from being inserted into the card connector 1 in an upside down orientation, that is, to prevent erroneous insertion. .

  Next, a method for assembling the terminal unit 50 having the above configuration will be described.

  FIG. 5 is a first diagram for explaining a method for assembling a terminal unit in the embodiment of the present invention, and FIG. 6 is a second diagram for explaining a method for assembling the terminal unit in the embodiment of the present invention. 5 and 6, (a) to (e) are diagrams for explaining each process of assembling the terminal unit. In (a) to (e), the subscript 1 means a top view, and the subscript. 2 means a cross-sectional view in the top view.

  The terminal unit 50 includes the support member 51 and the contact member 52 as described above. The support member 51 and the contact member 52 are separate members that are independent of each other, and both are manufactured, for example, by subjecting a conductive metal plate to processing such as punching and bending. The contact member 52 is preferably made of a thin plate material than the support member 51.

  Subsequently, the support member 51 is formed integrally with the housing 11 by a molding method called so-called insert molding or overmold molding, and is embedded and held in the bottom wall portion 11b. That is, the housing 11 is formed by filling (tempering) an insulating material into a cavity of a mold in which the support member 51 is set in advance, and the support member 51 is at least a part thereof, for example, the connection portion 51c. And the auxiliary | assistant fixing | fixed part 51e is embedded and hold | maintained at the bottom wall part 11b by being covered with the insulating material which comprises the bottom wall part 11b. As a result, the bottom of the terminal accommodating recess 16 is closed by the support main body 51a including the support 51b of the support member 51 at least over the entire range in the longitudinal direction, as shown in FIG. 5 (a2). .

  Subsequently, the contact member 52 is gripped by a gripping tool (not shown), and in the posture shown in FIGS. 5 (a1) and (a2), the terminal accommodating recess 16 whose bottom is closed by the corresponding support member 51. Positioned on top of. Specifically, in a plan view, the longitudinal axis of the contact member 52 is located on the same axis as the longitudinal axis of the support member 51, but the longitudinal center of the contact member 52 is the longitudinal axis of the support member 51. Positioned so that it is off the center of the direction and is located closer to one end (closer to the left end in the figure), and the center of one (left side in the figure) of the engaging portion 52d is located directly above the center of the corresponding wide recess 16b. Is done.

  Subsequently, the contact member 52 is in a posture as shown in FIGS. 5B1 and 5B2 while being held by the holding tool. Specifically, one end in the longitudinal direction (left end in the drawing) of the contact member 52 is lowered, and the one engaging portion 52d (left side in the drawing) enters the corresponding wide recessed portion 16b, and the supported portion 52c The tip is brought into contact with the support main body 51a of the support member 51 that closes the bottom of the wide recess 16b. In this case, the other (right side in the figure) engaging portion 52d is located on the narrowed portion 16c having a width smaller than that of the engaging portion 52d, and thus interferes with the protruding engaging portion 15 of the housing 11 and descends. I can't.

  Subsequently, the contact member 52 is in a posture as shown in FIGS. 5C1 and 5C2 while being held by the holding tool. Specifically, in the posture as shown in FIGS. 5B1 and 5B2, the contact member 52 is moved horizontally toward the other end in the longitudinal direction (the right end in the drawing) to enter the wide recess 16b. One of the positioned engaging portions 52d (left side in the figure) is caused to enter the recessed portion 16d of the wide recessed portion 16b and contact the protruding engaging portion 15. When the one engaging portion 52d comes into contact with the protruding engaging portion 15 in the recessed portion 16d, the contact member 52 becomes immovable toward the other longitudinal end. In this case, since the other engaging portion 52d is still located on the narrow throttle portion 16c, the other engaging portion 52d interferes with the protruding engaging portion 15 of the housing 11 and cannot be lowered.

  Subsequently, when a downward pressing force is applied to the contact portion 52b by the gripping tool or other jig and the contact portion 52b is pushed downward, the contact main body portion 52a is elastically deformed and contacted. The member 52 has a crushed shape. As a result, as shown in FIGS. 6D1 and 6D2, the distance between the engaging portions 52d at both ends in the longitudinal direction is widened, and the other engaging portion 52d is the other end in the longitudinal direction of the contact member 52. It moves further horizontally toward the other side, reaches just above the other wide concave portion 16b, descends and enters the wide concave portion 16b.

  Subsequently, when the downward pressing force applied to the contact portion 52b is released, the contact member 52 is restored to the original shape by the spring force of the contact main body portion 52a. Thereby, as shown in FIGS. 6E1 and 6E2, the distance between the engaging portions 52d at both ends in the longitudinal direction contracts, and the other engaging portion 52d has one end in the longitudinal direction of the contact member 52 ( It moves horizontally toward the left end in the drawing, enters the recessed portion 16d of the wide recessed portion 16b, and engages with the protruding engaging portion 15. At this time, the one engaging portion 52 d is already in contact with the protruding engaging portion 15, so that it cannot move toward the other end in the longitudinal direction of the contact member 52.

  Thereby, the assembly of the terminal unit 50 is completed, the engaging portions 52d at both ends in the longitudinal direction are positioned in the recessed portion 16d, and the contact member 52 is prevented from being detached from the terminal accommodating recessed portion 16.

  Next, the operation of the card connector 1 having the above configuration will be described. First, the operation when the card tray 161 is inserted will be described.

  First, the user inserts the card tray 161 containing the card 101 as the card module 102 from the insertion port 18 at the back of the card connector 1 between the housing 11 and the shell 61 with a finger or the like. Insert into the space.

  Here, as shown in FIG. 1, the upper surface of the card tray 161 faces upward, that is, faces the top plate portion 62 of the shell 61, and the front frame portion 165 is the front end portion of the card connector 1. Is inserted in a normal posture, that is, a normal posture. Further, the card 101 accommodated in the card tray 161 faces downward with the lower surface on which the electrode pads are disposed open, and the bottom wall portion of the housing 11 in which the terminal unit 50 is disposed. 11b, and the front end 111f faces the front end of the card connector 1.

  When the card tray 161 is inserted into the card insertion space formed between the housing 11 and the shell 61 from the insertion port 18, the card tray 161 enters the lower surface of the front frame portion 165 and the rear frame portion 162 and the space portion 166. The side frame portion 164 protruding downward from the lower surface of the accommodated card 101 is guided by the concave portions formed on the left and right sides of the bottom wall portion 11b of the housing 11 and advances in the card insertion space. That is, the card tray 161 is placed in the card insertion space with the lower surface of the side frame portion 164 protruding downward facing the upper surfaces of the left and right flange portions 11h located below the upper surface of the bottom wall portion 11b. To proceed.

  Here, since the contact member 52 of each terminal unit 50 is arranged so that the longitudinal direction thereof coincides with the insertion direction of the card tray 161 in the housing 11, the upper surface of the contact main body portion 52a is the contact portion 52b. Is a continuous inclined surface that gently falls toward both the front and rear sides in the insertion direction of the card tray 161. Therefore, when the card tray 161 advances in the card insertion space, even if the lower surface of the front frame portion 165, the lower surface of the card 101, etc. contact the contact main body portion 52a protruding upward from the upper surface of the bottom wall portion 11b. Since the contact main body 52a is not caught, the card tray 161 can proceed smoothly. Further, the contact member 52 is not damaged or broken. Similarly, the lower surface of the front frame portion 165, the lower surface of the card 101, and the like are not damaged or broken.

  By the way, when a card connector other than the card connector 1 is mounted on the electronic device, the user may not use the card connector 1. In such a case, the user may store the card tray 161 that does not contain the card 101, that is, the empty card tray 161 inserted into the card connector 1. As described above, even when the card tray 161 that does not contain the card 101 is inserted, the lower surface of the front frame portion 165 is the contact main body portion because the upper surface of the contact main body portion 52a is a gently inclined surface. 52a is not caught. Therefore, the contact member 52 is not damaged or broken, and the lower surface of the front frame portion 165 is not damaged or broken.

  Subsequently, when the user pushes and pushes the card tray 161 and the card tray 161 reaches a predetermined position of the card connector 1, the holding convex portions 85 a included in the left and right holding members 85 are formed on the card tray 161. It enters and engages in a holding recess 168 formed in the side frame 164. Thereby, the card tray 161 is held in a locked state at a predetermined position in the card connector 1. At this time, the first contact member 57 is displaced toward the front end portion 11f by being pushed by the front frame portion 165, and the first contact member 57 is separated from the second contact member 58, so that the card detection switch is turned off. It is detected that the card tray 161 has reached a predetermined position of the card connector 1.

  Further, when the card tray 161 moves forward to a predetermined position of the card connector 1, the action point portion 21a of the eject lever 21 is pushed by the front frame portion 165 and displaced toward the front end portion 11f. The force point portion 21b of the eject lever 21 is displaced toward the rear end portion 11r. Therefore, the push rod 22 including the engaging portion 22b that engages with the power point portion 21b slides in the direction of the rear end portion 11r, and the protruding amount of the operation portion 22a from the housing 11 is shown in FIGS. It becomes larger than the initial state.

  And when the card | curd 101 is accommodated in the tray 161 for cards, since the contact part 52b of the contact member 52 of each terminal unit 50 contacts and electrically connects with the corresponding electrode pad of the card | curd 101, the connector 1 for cards is connected. Data can be transmitted / received to / from the arithmetic means of the mounted electronic device.

  Next, an operation for discharging the card module 102 from the card connector 1 will be described.

  First, when the user pushes and pushes the operating portion 22a of the push rod 22 with fingers or the like or via an auxiliary member such as a pin, a needle, or a rod, the eject is engaged with the engaging portion 22b of the push rod 22. The power point portion 21b of the lever 21 is displaced toward the front end portion 11f. Therefore, the front frame portion 165 is pushed by the action point portion 21a of the eject lever 21, and the card tray 161 is displaced from the predetermined position toward the rear end portion 11r. At this time, since the force exerted by the user's fingers and the like is considered to be sufficiently large, when the user pushes and pushes the operation portion 22a of the push rod 22, the holding convex portion 85a of the holding member 85 and the card The engagement with the holding recess 168 of the side frame portion 164 of the tray 161 is released and the lock is released, and the card tray 161 is displaced from the predetermined position toward the rear end portion 11r.

  Further, since the contact member 52 of each terminal unit 50 is arranged so that the longitudinal direction thereof coincides with the insertion direction of the card tray 161 in the housing 11, the upper surface of the contact main body portion 52a has the contact portion 52b. The center is a continuous inclined surface that gently falls toward both the front and rear sides in the insertion direction of the card tray 161. Therefore, even when the card tray 161 moves in the card insertion space toward the rear end portion 11r, the lower surface of the front frame portion 165, the lower surface of the card 101, and the like protrude upward from the upper surface of the bottom wall portion 11b. Since the contact main body 52a does not get caught, the card tray 161 can move smoothly. Similarly, when the card 101 is not accommodated in the card tray 161, similarly, the lower surface of the front frame portion 165 is not caught on the contact main body portion 52a. As a result, the contact member 52 is not damaged or broken, and the lower surface of the front frame portion 165, the lower surface of the card 101, or the like is not damaged or broken.

  When the user pushes the push rod 22 to a position where the push rod 22 can be advanced most, the action point portion 21a of the eject lever 21 is displaced to a position as shown in FIG. At this time, the rear plate portion 163 of the card tray 161 protrudes sufficiently large from the insertion port 18 of the card connector 1. Therefore, the user can pull out and eject the card tray 161 from the card connector 1 by gripping the rear plate portion 163 with fingers or the like.

  As described above, in the present embodiment, the terminal unit 50 includes the support member 51 including the elongated flat plate-like support body 51a, the elastic elongated plate-like contact body 52a, and the longitudinal direction of the contact body 52a. A contact member 52 including a contact part 52b formed at the center and a pair of supported parts 52c connected to both ends in the longitudinal direction of the contact main body part 52a. The support member 51 and the contact member 52 are separate from each other. The pair of supported portions 52c are members that are supported from below without being fixed by the support main body 51a, and the contact portions 52b protrude upward.

  As a result, the contact member 52 functions as an elastically deformable leaf spring in the form of a simple support beam at both ends in a state where both ends are not fixed and supported from below, shortening the overall length of the terminal unit 50, and the contact portion 52 b The amount of elastic displacement in the vertical direction can be increased, and the contact state with the electrode pad of the card 101 which is the counterpart terminal can be reliably maintained.

  The pair of supported portions 52c can slide on the support main body 51a. Therefore, even when the contact portion 52b is elastically displaced in the vertical direction and the contact main body portion 52a is elastically deformed, the conductive state between the contact member 52 and the support member 51 is reliably maintained.

  Further, the contact main body 52a has the maximum width dimension at the center in the longitudinal direction, and the width dimension gradually decreases toward both ends in the longitudinal direction. Thereby, when the contact main body part 52a is elastically deformed, the bending stress becomes uniform along the length, so that the contact main body part 52a is prevented from being damaged.

  Furthermore, the distance from the support main body 51a to the contact main body 52a is the maximum at the contact 52b, and gradually decreases toward both ends in the longitudinal direction of the contact main body 52a. Accordingly, the upper surface of the contact main body 52a is a continuous inclined surface that gradually falls toward the supported portions 52c at both ends with the contact portion 52b as the center. Therefore, when the card tray 161 is inserted and ejected, The lower surface of the tray 161 and / or the card 101 can move smoothly without being caught by the contact main body 52a.

  Further, the contact portion 52b can be elastically displaced in the vertical direction, and the distance between the supported portions 52c expands and contracts when the contact portion 52b is displaced in the vertical direction. As a result, the contact member 52 maintains the state where the upper surface of the contact main body portion 52a is a continuous inclined surface gently descending toward the supported portions 52c at both ends with the contact portion 52b as the center. It can function as a simple support beam at both ends in a state of being supported from below without being fixed.

  Further, the contact member 52 includes an engagement portion 52d extending from each supported portion 52c in the width direction of the contact main body portion 52a, and the engagement portion 52d is formed on the bottom wall portion 11b that holds the support member 51. It is possible to engage with the protruding engagement portion 15. The protruding engagement portion 15 includes a flange portion 15a extending toward both ends in the longitudinal direction of the support main body portion 51a. In the state where no external force is applied to the contact member 52, the engagement portion 52d The contact member 52 and the support member 51 are prevented from separating from each other in the recessed portion 16d between the contact portion 52a and the portion 51a.

  In the present embodiment, the card connector 102 having an electrode pad 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 a terminal unit 50 that contacts an electrode pad of the card module 102 is disposed. Further, the contact main body 52 a of the terminal unit 50 extends in the insertion and ejection directions of the card module 102.

  Thus, when the card tray 161 is inserted and ejected, the lower surface of the card tray 161 and / or the card 101 can be smoothly moved without being caught by the contact main body 52a.

  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 terminal unit and a card connector including the terminal unit.
