Description

  The present invention is used for mounting an information recording card such as a mobile phone, a personal digital assistant (PDA), a SIM card (Subscriber Identity Module) that extracts personal information by mounting it on a notebook personal computer or the like. The present invention relates to a card connector and a connector terminal used.

  For example, when there are many opportunities to use a single mobile phone across countries such as Europe, SIM cards used in mobile phones can be used in different countries by replacing the SIM card issued in that country. You can use that mobile phone. In particular, a SIM card can be called at a lower call charge if purchased in the country of use.

  As a conventional card connector, as shown in FIGS. 18A and 18B, a card accommodating portion 103 formed between the case 101 and the cover 102 is inserted into the card accommodating portion 103 in the longitudinal direction. There is known a card connector 100 in which a plurality of connector terminals 104 are assembled and a SIM card, that is, an information recording card 200 is vertically inserted into the card housing portion 103, that is, a short side is inserted toward the card housing portion 103 (for example, , See Patent Document 1). In the following description, inserting the short side toward the card accommodating portion is referred to as vertical insertion, and inserting the long side toward the card accommodating portion is referred to as horizontal insertion.

JP 2007-26919 A

  However, in the card connector 100 disclosed in Patent Document 1, when the information recording card 200 is inserted horizontally instead of vertically, the longitudinal direction of the connector terminal 104 is changed to the insertion / extraction direction of the card housing portion 103. It becomes disadvantageous in terms of cost, such as preparing different molds by arranging. Therefore, there is a demand for a card connector for lateral insertion that can be manufactured without significant changes in the mold.

  Further, in the card connector 100 disclosed in Patent Document 1, when it is dropped, the connector terminal 104 being energized is momentarily separated from the card-side contact on the information recording card 200 side, and the signal, power, etc. There is a risk of causing a so-called momentary interruption in which the minute current is temporarily interrupted. If the instantaneous interruption time is long, information electrically recorded in the information recording card 200 may be lost, or parts in the mobile phone may be damaged. Therefore, sufficient resistance to instantaneous interruption is desired.

  The present invention has been made in view of the above-described circumstances, and the object thereof is sufficient in that it can be manufactured for horizontal insertion without greatly changing the mold with the same terminal arrangement as that of a conventional card connector for vertical insertion. An object of the present invention is to provide a card connector having instantaneous disconnection resistance and a connector terminal capable of obtaining sufficient instantaneous disconnection resistance even in a small size.

The above object of the present invention is achieved by the following configurations.
(1) An insulator having a connector terminal fixed thereto, a cover that is assembled to the insulator and forms a card housing portion between the insulator, and a fixing bracket for fixing the insulator to a substrate by soldering,
A card connector used for extracting the information of the information recording card by electrically connecting the connector terminal to the information recording card in association with the mounting of the information recording card storing the information in the card accommodating portion. There,

The card connector according to claim 1, wherein the arm piece is twisted between the terminal base and the contact.

(2) The card connector according to (1), wherein the arm piece of the connector terminal is formed narrower from the terminal base toward the contact.

(3) A pair of plate-like arm pieces cantilevered from the terminal base and an invitation surface inclined with respect to the moving direction of the mating contact are provided to be connected to the free end of the arm piece. A connector terminal, wherein the arm piece is twisted between the terminal base and the contact.

(4) The connector terminal according to (3), wherein the arm piece is formed narrower from the terminal base toward the contact.

  According to the card connector having the configuration of the above (1), the connector terminal extends in a direction intersecting the insertion direction of the information recording card into the card housing portion and is cantilevered from the terminal base. A card-shaped arm piece, and a convex contact having a guide surface inclined with respect to the insertion direction and connected to the free end of the arm piece. The contact can be reliably brought into contact with the horizontally-recorded information recording card. Thereby, the card connector for horizontal insertion can be easily manufactured only by changing the position of the card insertion slot in the mold by diverting the mold of the terminal arrangement of the conventional card connector for vertical insertion for horizontal insertion. Therefore, it is not necessary to change the arrangement of the connector terminals of the conventional mold, and it can be manufactured advantageously in terms of cost.

  In addition, the total length of the connector terminal can be shortened by the cantilever support structure, and when the information recording card is inserted into the card housing portion, the connector terminal passes through the inclined invitation surface on the contact side of the contact. It is possible to reliably contact the information recording card.

  Also, the rigidity can be increased by making the arm piece a twisted structure, and the elastic repulsion force when the information recording card is brought into contact with the contactor can be increased to set the natural frequency to a preferable high value. . Therefore, it is possible to obtain a connector terminal having sufficient instantaneous interruption resistance due to a predetermined contact pressure. In addition, high rigidity can be obtained even if the wall thickness is reduced as compared with a simple plate-shaped arm piece, so that the amount of material used can be reduced and the weight can be reduced.

  According to the card connector having the above configuration (2), the contact side can move more easily than the terminal base, so that stress applied to the contact can be absorbed on the contact side, and the stress can be concentrated on the base end. Absent. Therefore, damage to the connector terminal is prevented and durability is improved.

  According to the connector terminal having the configuration (3), the contact can be brought into contact with the connected body even when the longitudinal direction of the connector terminal is arranged to intersect the traveling direction of the connected body. Thereby, since it can be remodeled into the mold of the card connector for horizontal insertion, without changing the terminal arrangement of the mold of the conventional card connector for vertical insertion, it can manufacture advantageously in terms of cost.

  Further, the total length of the connector terminal can be shortened by the cantilever support structure, and the information recording card can be reliably contacted via the inclined invitation surface of the contact.

  Further, the arm piece can have a twisted structure to increase the rigidity, and the elastic repulsive force when the contacted body is brought into contact with the contact can be increased to set the natural frequency to a preferable high value. . Therefore, it is possible to obtain sufficient instantaneous interruption resistance due to the predetermined contact pressure. In addition, since the thickness can be reduced as compared with a simple plate-shaped arm piece, the amount of material used can be reduced and the weight can be reduced.

  Moreover, according to the connector terminal of the structure of said (4), since the contact side moves more easily than a terminal base part, the stress given to the front-end | tip part can be absorbed in a contactor side, and stress concentrates on a base end part. There is no. Therefore, damage to the connector terminal is prevented and durability is improved.

  According to the present invention, it is possible to manufacture a card connector for horizontal insertion with the same terminal arrangement as that of a conventional card connector for vertical insertion, and it is possible to reduce the mold remodeling and to easily make a card connector suitable for horizontal insertion. Can be manufactured. Moreover, since the rigidity of the connector terminal is increased, it is possible to provide a card connector and a connector terminal that have sufficient instantaneous interruption resistance. Furthermore, even if the connector terminal is small, it can exhibit high elastic force, so that the connector terminal can be reduced in height and the card connector can be made thinner. As a result, a device such as a mobile phone to which the card connector is attached can be thinned.

  As shown in FIG. 1, a card connector 10 according to an embodiment of the present invention includes an insulator 11, six connector terminals 12 integrally formed with the insulator 11, a cover 13 assembled to the insulator 11, and the insulator 11. Is fixed to the substrate with solder, and the information recording card 70 is detachably held.

  The information recording card 70 is a unified standard SIM card (Subscriber Identity Module) used in countries around the world, and is a rectangular plate having a pair of long sides 71 and a pair of short sides 72. It is a state. The information recording card 70 has a plurality of card side contacts (not shown) corresponding to the arrangement of the connector terminals 12.

  The information recording card 70 stores telephone contract information such as a telephone number, a user ID, and a charge, a personal e-mail address, and the like in a built-in recording device (RAM), and performs calculation processing of information. The information can be extracted from the card side contact.

  The insulator 11 is formed in a U shape in a longitudinal sectional view using a non-conductive, for example, hard resin material. The insulator 11 has an insulator body 14 having a flat plate shape, and has a pair of guide plates 15 on both sides of the insulator body 14.

  The insulator body 14 has six terminal windows 16 in two rows of three in the insertion direction of the information recording card 70 indicated by an arrow in FIG.

  The connector terminal 12 has a base end portion 17 fixed to the insulator body 14, a contact end 18 at the tip end, and the base end portion 17 and the contact end 18 are connected by an arm 19.

  The cover 13 is press-formed into a substantially U shape using a steel material having conductivity, such as stainless steel, and functions as a shield for preventing disturbance. The cover 13 has a cover body 20 having a flat plate shape, and has a pair of guide plate insertion portions 21 on both sides of the cover body 20.

  The cover 13 is assembled to the insulator 11 by inserting the guide plate insertion portion 21 into the guide plate 15 of the insulator 11. A card housing portion 22 is formed between the cover main body 20 of the cover 13 and the insulator main body 14 of the insulator 11. The information recording card 70 inserted into the card accommodating portion 22 is loaded by the cover body 20 and the insulator body 14 so as to be freely inserted and removed.

  As shown in FIG. 2, the insulator 11 is provided with a fixture 42 for fixing the insulator 11 to the substrate by soldering to both guide plates 15. The fixing bracket 42 has a flexible piece 23 for wearing a cover. The flexible piece 23 prevents the cover 13 from being detached and fixed when the guide plate insertion portion 21 of the cover 13 is inserted into the guide plate 15, and functions as an electrical connection piece with the cover 13. The fixing bracket 42 is in electrical contact with the cover 13 and has a function of dropping the ground to the substrate by being fixed to the substrate with solder.

  As shown in FIG. 3, the connector terminal 12 is mounted such that the contact 18 protrudes upward from the terminal window 16 of the insulator body 14.

  As shown in FIGS. 4 and 5, the base end portion 17 of the connector terminal 12 is folded back on the back surface of the insulator body 14 and fixed to the insulator body 14. The base end portion 17 is electrically connected to a control circuit (not shown) in a device such as a mobile phone on which the card connector 10 is mounted.

  Next, the detailed structure of the connector terminal 12 will be described with reference to FIGS. 6, 7, 8, 9, and 10.

  As shown in FIG. 6, the connector terminal 12 is formed in a rectangular plate shape which is a cantilever support structure in which the base end portion 17 is fixed to the insulator 11. The connector terminal 12 has a tongue piece 24 at the end of the contact 18. The tongue piece 24 is formed to project in an L-shaped cross section, and is locked to the lower surface of the terminal window 16 of the insulator 11 so that the projecting dimension (see FIG. 11) L1 of the contact 18 is, for example, a predetermined value of 0.3 mm. A predetermined contact pressure is obtained by setting the value.

  The arm 19 has a thinned portion 25 formed at the center thereof, and has a pair of arm pieces 26 on both sides of the thinned portion 25. The arm piece 26 is narrower in width from the base end portion toward the tip end portion.

  As shown in FIG. 7, the arm 19 has a cantilever support structure so that the distal end side protrudes upward in FIG. 7, that is, toward the contact side to the information recording card 70. As a result, the connector terminal 12 accumulates an elastic repulsive force toward the information recording card 70.

  As shown in FIG. 8, since the arm 19 is formed to have a width that is the same as that of the contact 18, deformation such as a change in posture of the contact 18 due to a load when the information recording card 70 is inserted. Can be reduced.

  Since the arm piece 26 is formed so that the width dimension of the contact connecting portion 28 at the distal end is smaller than the base end 27, the stress applied to the contact 18 due to the insertion of the information recording card 70. Can be absorbed on the contact side, and stress can be prevented from being concentrated on the base end portion 27.

  The contact 18 includes side curved inclined surfaces 29 and 30 extending to the contact connecting portion 28 side of the arm piece 26, a front curved inclined surface 31 extending forward in the longitudinal direction of the connector terminal 12, and a connector. And a rear curved inclined surface 32 extending rearward in the longitudinal direction of the terminal 12. The curved inclined surfaces 29, 30, 31, and 32 are integrally connected so as to form a substantially hemispherical shape that is inclined with respect to the information recording card insertion direction and is convex toward the contact side to the information recording card 70. ing. The curved inclined surfaces 29 and 30 continuous with the arm piece 26 function as an invitation surface for smoothly guiding the card side contact to the apex of the contact 18 when the information recording card is inserted.

  Since the contact 18 is connected to the contact connecting portion 28 at the distal end portion of the pair of arm pieces 26 via the side curved inclined surfaces 29 and 30, the contact is simply connected to the central portion of the arm. Rigidity can be increased compared to the above.

  As shown in FIGS. 9, 10 </ b> A, and 10 </ b> B, the arm piece 26 is formed to be slightly curved in the width direction by press working, and the base end portion 27 and the contact connecting portion 28. And a twisted portion 33. Therefore, the arm piece 26 has a base end portion 27 formed on the same plane as the base end portion 17 of the connector terminal 12, and a contactor connection portion 28 formed on an inclined surface continuous with the contactor 18. 28 is inclined with respect to the base end portion 27. At this time, since the angle C1 formed by the contact connecting portion 28 of the pair of arm pieces 26 is set to 90 degrees to 120 degrees, for example, the invitation angle C2 of 30 degrees to 45 degrees with respect to the information recording card 70 is set to the connector. The terminal 12 can be set.

  Since the arm 19 is formed by the pair of arm pieces 26 having the twisted portion 33 extending in the longitudinal direction, the elastic repulsion force when the information recording card 70 is brought into contact with the contact 18 can be increased. Further, the same elastic repulsive force can be obtained even if the thickness of the entire connector terminal 12 is reduced and the length thereof is shortened as compared with a simple plate having arms.

  As shown in FIG. 11, the connector terminal 12 is arranged in the direction of the arrow shown in FIG. 11 (the X1 direction shown in FIG. 8, that is, the arrow direction shown in FIG. 1), that is, in one direction intersecting the longitudinal direction of the connector terminal 12. Electrical connection can be made to the information recording card 70 inserted (moved) by insertion through the one side curved inclined surface 29 of the contact 18.

  Further, the connector terminal 12 is connected to the information recording card 70 inserted by lateral insertion in the X2 direction shown in FIG. 8 opposite to the X1 direction, that is, the other direction intersecting the longitudinal direction of the connector terminal 12, and the other of the contacts 18 is inserted. Electrical connection can be made through the side curved inclined surface 30.

  Thus, even if the information recording card 70 is inserted in the direction intersecting with the longitudinal direction of the connector terminal 12 in the card connector for lateral insertion, the connector terminal 12 passes through the side curved inclined surface 30 of the contact 18. The electrical connection can be made reliably.

  Further, when the contact 18 is attached to the card connector for vertical insertion, the information recording card 70 inserted by vertical insertion in one direction parallel to the Y1 direction shown in FIG. In addition, electrical connection can be made via the front curved inclined surface 31 of the contact 18.

  That is, the connector 18 can reliably contact the contact 18 on the card side contact even when the information recording card 70 is inserted in either the longitudinal direction or the direction intersecting the longitudinal direction.

  Next, a modified example of the connector terminal according to the embodiment of the present invention will be described with reference to FIGS. 12, 13, 14, 15, 16, and 17. This modification is preferable when it is attached to a vertical insertion type card connector.

  As shown in FIGS. 12 and 13, the connector terminal 41 of this modification has a cantilever support structure in which the base end portion 17 is fixed to the insulator 11, and the contact 18 side of the arm 19 has a short side. It is formed in a trapezoidal plate shape.

  As shown in FIGS. 14 and 15, the arm 19 has a lightening portion 25 formed at the center thereof. The pair of arm pieces 26 on both sides of the lightening portion 25 are formed such that the width dimension of the contact connecting portion 28 at the distal end is smaller than the base end 27, and the contact connecting portion 28 is the contact 18. And are arranged so as to form the same surface. Thereby, since the contactor 18 can be reduced in size compared with the connector terminal 12 shown in FIG. 8, weight reduction can be achieved.

  As shown in FIG. 16, the connector terminal 41 is inserted (progressed) in the direction of the arrow shown in FIG. 16 (the Y2 direction shown in FIG. 14), that is, in one direction parallel to the longitudinal direction of the connector terminal 12. ) Electrical connection can be made to the information recording card 70 via the contact connecting portion 28 of the arm piece 26.

  Further, as shown in FIG. 17, the connector terminal 41 extends vertically in the arrow direction (Y1 direction shown in FIG. 14) shown in FIG. 17 opposite to the Y2 direction, that is, in the other direction parallel to the longitudinal direction of the connector terminal 12. Electrical connection can be made to the information recording card 70 inserted by insertion through the front curved inclined surface 31.

  That is, the contact 18 can reliably contact the information recording card 70 inserted along the longitudinal direction of the connector terminal 41.

  As described above, according to the card connector 10 of the present embodiment, the connector terminal 12 is fixed to the insulator 11 with its longitudinal direction intersecting the insertion direction of the information recording card 70 into the card housing portion 22, and the connector Since the contact 18 of the terminal 12 has curved inclined surfaces 29 and 30 as invitation surfaces inclined with respect to the insertion direction, the conventional terminal arrangement of the mold of the card connector for vertical insertion is used as it is. The card connector 10 for horizontal insertion can be manufactured by slightly modifying the mold.

  Further, according to the card connector 10, the total length of the connector terminals 12 and 41 can be shortened by the cantilever support structure, and when the information recording card 70 is inserted into the card accommodating portion 22, the connector terminals 12 and 41 are arranged. Can be reliably brought into contact with the information recording card 70 via the curved inclined surfaces 29 and 30 on the contact side of the contact 18 at the tip.

  Further, according to the card connector 10, the arm 19 has increased rigidity due to the configuration having the twisted portion 33, and the elastic repulsion force when the information recording card 70 is brought into contact with the contactor 18 is increased so that the natural frequency is preferable. Since it can be set to a high value, connector terminals 12 and 41 having sufficient instantaneous interruption resistance due to a predetermined contact pressure can be obtained. Further, the same elastic repulsive force can be obtained even if the wall thickness is reduced and the length is reduced as compared with a simple plate-shaped arm. Therefore, the amount of material used can be reduced and the weight can be reduced.

  Further, according to the card connector 10, since the contact connecting portion 28 on the contact 18 side of the arm piece 26 is formed narrower than the base end portion 17, the contact side is easier to move than the terminal base portion. Therefore, the stress applied to the contact 18 side can be absorbed on the contact 18 side, and the stress is not concentrated on the base end portion 17. Therefore, the connector terminals 12 and 41 are prevented from being damaged and the durability is improved.

  Further, according to the connector terminal 12 of the present embodiment, when the longitudinal direction is arranged on the card connector for horizontal insertion so as to intersect the advancing direction of the information recording card 70, the contact 18 is surely attached to the information recording card 70. Can be contacted.

  Further, according to the connector terminals 12 and 41, the total length can be shortened by the cantilever support structure, and the curved terminal surfaces 29, 30, 31, and 32 provided on the contact side of the contact 18 at the tip end portion can be used. The information recording card 70 can be reliably contacted.

  Further, according to the connector terminals 12 and 41, the arm 19 has a torsional portion 33, so that the rigidity is increased, and the elastic repulsive force when the information recording card 70 is brought into contact with the contact 18 is increased to increase the natural frequency. Can be set to a preferable high value, so that it is possible to obtain sufficient instantaneous interruption resistance by a predetermined contact pressure. Further, the same elastic repulsive force can be obtained even if the wall thickness is reduced and the length is reduced as compared with a simple plate-shaped arm. Therefore, the amount of material used can be reduced and the weight can be reduced.

  Further, according to the connector terminals 12 and 41, the contactor connection part 28 on the contactor 18 side of the arm 19 is formed narrower than the base end part 27, so that the contactor side is closer to the base end part 17. Therefore, the stress applied to the contact 18 side can be absorbed by the contact 18 side, and the stress is not concentrated on the base end portion 17. Therefore, the connector terminals 12 and 41 are prevented from being damaged and the durability is improved.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimension, numerical value, form, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  For example, the connector terminal is inserted (in the case where the longitudinal direction is fixed to intersect the insertion (advance) direction of the information recording card and the longitudinal direction is fixed to the insertion (advance) direction of the information recording card. For example, it may be fixed by being inclined by a preferable angle such as 45 degrees with respect to the (traveling) direction. Of course, even in this case, the contact can be reliably brought into contact with the information recording card.

  Also, a plurality of card accommodating portions can be formed between the insulator and the cover, and a plurality of information recording cards can be removably accommodated in these card accommodating portions.

  Needless to say, the number of connector terminals is not limited to six as shown, and can be appropriately selected and set according to the number of card-side contacts that increase or decrease in accordance with the capacity of the information recording card, that is, the amount of stored items.

  In addition, the connector terminal can be applied to various connectors connected to a general mating connector or the like instead of being provided in the illustrated card connector.
