Description

  The present invention relates to a contact fitting and a portable electronic device having the same.

  In recent years, various portable electronic devices such as mobile communication terminals such as PHS (Personal Handy-phone System) and mobile phones, and information terminals such as PDA (Personal Digital Assistant) and GPS (Global Positioning System) have been proposed and provided. ing.

  In particular, the development and popularization of portable electronic devices such as mobile phones and PHSs are remarkable, and the advancement and miniaturization of peripheral technologies are also progressing. On the other hand, since a portable terminal is always carried by a user, resistance to predetermined vibrations and impacts is required. However, in the conventional portable terminal, the power terminal of the battery and the contact fitting of the portable terminal are temporarily separated due to a strong impact, and there is a possibility that an instantaneous interruption may occur. The strong impact is, for example, an impact load due to a drop or an impact load when the bi-fold casing is closed with force.

  Therefore, in general, in preparation for a momentary interruption, a capacitor is mounted inside the terminal to accumulate charges. However, along with the miniaturization of the mobile terminal, the mounting area of the element is being limited, and there is a problem that the production cost increases because a small and high-capacitance capacitor is expensive.

Along with this, various techniques have been proposed. For example, Patent Document 1 discloses a pin-type power receiving power terminal structure in which at least two terminals having different elastic forces are concentrically arranged to suppress instantaneous interruption. In Patent Document 2, a clock signal supplied from an RTC circuit (real-time clock IC) is counted when the voltage falls below a predetermined voltage, and when it is determined that the instantaneous interruption occurs according to the number of counts, the instantaneous interruption recovery is automatically recovered. A circuit is disclosed.
JP 2008-85739 A JP 2001-251783 A

  However, in the technology of Patent Document 1, even if the elastic forces of the plurality of terminals are made different, the impact load is applied to all the terminals simultaneously when receiving an impact from the outside. From this, it was naturally separated at the same time, so that the instantaneous interruption could not be suppressed. Further, in the technique of Patent Document 2, since various elements constituting the instantaneous interruption recovery circuit have to be mounted, it has a form that goes against the downsizing of portable electronic devices. Also, in terms of cost, it would naturally be expensive to implement an instantaneous interruption recovery circuit.

  As described above, when a momentary disconnection occurs due to the separation of the contact fittings, an impact load due to a drop, an impact load when the bi-fold casing is closed with force, and the like are factors. In some cases, the battery moves and strikes the contact fitting, or the contact fitting itself bends due to acceleration. In either case, an instantaneous interruption occurs when the contact fitting receives a force in the separating direction. Here, it is possible to increase the elasticity of the contact fitting so that it does not bend easily. However, this makes it difficult to install the battery, and in addition, the battery's electrodes are always subjected to strong stress from the contact fitting. Therefore, it becomes a cause of rust (stress corrosion). That is, the contact metal fittings are required to have contradictory performances such as low elasticity and being difficult to separate from the battery electrode.

  Accordingly, the present invention has been made to solve the above-described problems, and provides a contact fitting and a portable electronic device that can suppress the occurrence of instantaneous interruption of the electronic device by improving vibration and impact resistance. The purpose is to do.

  In order to solve the above-described problems, a representative configuration of the contact fitting according to the present invention is a contact fitting having at least two contact pieces that contact the same electrode, and one contact piece is separated from the electrode. When deformed, another contact piece is deformed in a contact direction approaching the electrode.

  With such a configuration, any one of the contact pieces can be brought into contact with the electrode, and occurrence of instantaneous interruption of the electronic device can be suppressed. As a result, the instantaneous interruption recovery circuit can be omitted, and the mounting area and cost can be reduced.

  Even if at least one of the contact pieces has a loop shape, the width is increased by being deformed in the separation direction, the other contact pieces are urged, and the other contact pieces are deformed in the contact direction. Good. Thereby, it is possible to suitably deform (push up) another contact piece in the contact direction.

  At least one of the contact pieces has a substantially triangular portion formed by bending the contact piece itself at the tip, and the triangular portion urges another contact piece when receiving a force in the separation direction. In addition, the base of the contact piece may be deformed. Thereby, the triangular part which can be regarded as a rigid body can be formed in the front-end | tip of a contact piece, and another contact piece can be urged | biased reliably.

  The base of the contact piece may be bent with an inclination with respect to the contact direction. Thereby, since the contact piece is easily bent in a direction orthogonal to the base portion, the direction in which deformation is easy can be varied.

  In the case of providing at least three contact pieces, a double-structured C-shaped contact piece folded back at the tip in the contact direction and two loop-shaped contacts arranged on both sides of the C-shaped contact piece When the loop-shaped contact piece is deformed in the separation direction, the C-shaped contact piece may be urged so as to be sandwiched from both sides and extended in the contact direction. As a result, the C-shaped contact piece is strong against the force from the horizontal direction and extends in the contact direction by the urging force from the orthogonal direction, so that it can be applied to the battery (electrode) by combining with the loop-shaped contact piece. Contact can be maintained.

  At least two contact pieces may be provided, and the directions in which deformation is easy may be different. As a result, even if one of the contact pieces deforms due to an impact, the other contact piece does not deform, so that contact with the battery can be maintained.

  At least two contact pieces are provided, and the elasticity of each may be different. Thereby, since one contact piece deform | transforms preferentially and the other contact piece is urged | biased, the deformation | transformation to the separation direction of the other contact piece is prevented, and the contact | abutting with respect to a battery can be maintained.

  In order to solve the above-described problems, a typical configuration of a portable electronic device according to the present invention is configured such that when a battery and one contact piece are deformed in a separating direction away from the battery, the other contact piece is biased. And a portable terminal main body having a contact fitting that is deformed in a contact direction approaching the battery, wherein the battery has an electrode that contacts the contact fitting.

  With this configuration, any of the contact pieces can be brought into contact with the electrode, and occurrence of instantaneous interruption of the mobile terminal can be suppressed. As a result, the capacity of the capacitor can be reduced or the instantaneous interruption recovery circuit can be omitted, so that the mounting area can be reduced and the cost can be reduced.

  The components corresponding to the technical idea of the contact metal fitting and the description thereof can be applied to the portable electronic device.

  ADVANTAGE OF THE INVENTION According to this invention, the contact metal fitting and portable electronic device which can suppress generation | occurrence | production of the instantaneous interruption of an electronic device by improving a vibration and impact tolerance can be provided.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiment are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same functions and configurations are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. . In this specification, a direction approaching the battery is defined as a contact direction, and a direction away from the battery is defined as a separation direction.

(First embodiment)
FIG. 1 is a perspective view of a contact fitting 100 according to the first embodiment. The contact metal fitting 100 is made of a single sheet metal and includes a contact piece 110a, a contact piece 110b, a flat portion 130, and the other end connecting portion 132. The contact piece 110 a and the contact piece 110 b are connected to the other end connection part 132 through the flat part 130. The other end connecting portion 132 is joined to an electric circuit (not shown) by solder or the like. The shape of the flat part 130 may be changed as appropriate according to the mounting location of the contact metal fitting 100 (it may not be flat).

  The contact piece 110a has a cantilevered loop shape. In the present embodiment, the loop shape is a rhombus that is bent stepwise, and includes a base 112a, a first folded portion 114a, a second folded portion 116a, and a third folded portion 118a. In FIG. 1, the base portion 112a is bent in a direction away from the contact piece 110b with respect to the flat portion 130, but may be a reverse loop shape bent in a direction approaching the contact piece 110b. Moreover, it is good also as circular or an ellipse instead of a rhombus.

  The contact piece 110b has a shape in which a triangular portion (hereinafter referred to as “triangular portion 120”) formed by bending the contact piece 110b itself at the tip is cantilevered. Specifically, the base portion 112b, the first folded portion 114b, the second folded portion 116b, and the third folded portion 118b are configured. The base 112b is bent in a direction approaching the contact piece 110a with respect to the flat portion 130.

  In the contact piece 110b, the tip of the second folded portion 116b is in contact with the base portion 112b and forms a triangular portion 120 that can be regarded as a rigid body. By setting the tip of the contact piece 110b to the triangular portion 120, the contact portion 122b is disposed in the vicinity of the battery 140, and the first folded portion 114a is formed as an inclined surface having an angle that sinks under the loop shape of the contact piece 110a. it can. Note that the shape is not necessarily a triangle, and may be a polygon such as a quadrangle, or a circle or an ellipse.

  The contact piece 110a and the contact piece 110b are in contact with the battery 140 at the contact portions 122a and 122b, respectively. The current from the battery 140 is transmitted to the other end connecting portion 132 and is conducted to other circuits. In the present embodiment, the contact portions 122a and 122b are the intersections of the base portions 112a and 112b and the first folded portions 114a and 114b, but the first folded portions 114a and 114b may be contact points. Good. That is, you may contact | abut with the battery 140 in the surface of contact piece 110a, 110b.

  FIG. 2 is a diagram showing a direction in which the contact piece 110a and the contact piece 110b of the contact metal fitting 100 are easily deformed. FIG. 3 is a diagram for explaining the deformation of the contact fitting 100. FIG. 3A shows a case where the contact piece 110a is deformed in the separation direction, and FIG. 3B shows a case where the contact piece 110b is separated. The case where it is deforming in the direction is shown. Note that “easy to deform” means that when a force is applied from a predetermined direction, the contact pieces 110a and 110b are easily deformed in that direction.

  As shown in FIG. 2, the contact piece 110a is easily deformable in the separation direction. This is because the contact piece 110a has a generally rhombic loop shape, and a moment of force acts on each vertex when the contact piece 110a is deformed. And as shown to Fig.3 (a), when it deform | transforms in a separation direction, it will be crushed and the width | variety of the contact piece 110a will spread, and the contact piece 110b will be urged | biased. As a result, the base portion 112b of the contact piece 110b is deformed and the triangular portion 120 (the contact portion 122b) is pushed up in the contact direction.

  As shown in FIG. 2, the contact piece 110b can be easily deformed in a direction inclined with respect to the separation direction, that is, in a direction orthogonal to the base portion 112b. This is because only the base 110b bends because it has a triangular portion 120 that can be regarded as a rigid body at the tip. And as shown in FIG.3 (b), when it deform | transforms in a separation direction, it will fall down toward the contact piece 110a and will urge the contact piece 110a. Then, since the contact piece 110a is crushed and deformed in the width direction, the contact portion 122a which is the tip thereof is extended in the contact direction. In addition, the action of pushing the contact piece 110a in the contact direction is also exerted by the triangular portion 120 entering the lower side of the loop shape of the contact piece 110a.

  With such a configuration, even when one of the contact pieces 110a and 110b is deformed in a separating direction away from the battery 140 due to an impact, the other contact pieces 110b and 110a can be deformed in a contact direction approaching the electrode. Therefore, the contact pieces 110a and 110b vibrate so as to be alternately separated from and contacted with the electrodes of the battery 140, and repeat the states of FIG. 3A and FIG. Thereby, since any one of the contact pieces 110a and 110b can be kept in contact with the battery 140, occurrence of instantaneous interruption of the electronic device can be suppressed.

  Even if there is a moment when both contact pieces 110a and 110b are separated from each other, the separation time is extremely short as compared with the conventional contact piece, and it is sufficient to provide a small-capacitance capacitor. For these reasons, the number of capacitors and the mounting area of the capacitor can be reduced and the instantaneous interruption recovery circuit can be omitted. Therefore, the apparatus can be reduced in size and cost.

  In addition, when an impact load is applied, which contact piece leaves first and which contact piece maintains contact first becomes a problem.

  However, as described above, since the direction in which the contact pieces 110a and 110b are easily deformed is different, the contact piece that is easily deformable in that direction is first separated depending on the direction of the impact load.

  For example, when an impact load in the separation direction is received due to a drop or the like, the deformation direction of the contact piece 110a is the separation direction. Therefore, the contact piece 110a is deformed more and biases the contact piece 110b. Is pushed up toward the battery, and the contact with the battery 140 can be maintained. Also, for example, when an impact load is applied in a direction orthogonal to the separation direction, the contact piece 110b is deformed more and crushes the loop shape of the contact piece 110a, so that the contact piece 110a expands toward the battery 140. Contact with the battery 140 can be maintained.

  FIG. 4 is a view for explaining the configuration of the contact piece 110a and the contact piece 110b having different elasticity of the contact fitting 100. FIG. As shown in FIG. 4, the widths of the contact pieces 110a and 110b may be varied to vary the elasticity. As a result, the contact piece having low elasticity is preferentially deformed and biases the contact piece having high elasticity, so that the contact piece having high elasticity is prevented from being deformed in the separation direction, and the contact with the battery 140 can be maintained. . In FIG. 1, the width of the contact piece 110a is made narrower than that of the contact piece 110b to reduce elasticity. Therefore, when an impact load in the separation direction is received, the contact piece 110a is more reliably deformed, and the contact piece 110b can be urged to maintain contact with the battery 140.

  In addition, as shown in FIG. 4, the plate | board width becomes narrow as the contact piece 110a goes to the front-end | tip. As a result, the tip portion is more easily bent than the base portion 112a, and the mass of the tip portion can be reduced, so that the deformation of the base portion 112a can be reduced. As a result, the contact piece 110a can be prevented from being deformed outward (downward right in the figure), and the contact piece 110b can be more reliably biased.

  Although not shown, a case may be attached around the contact fitting 100 (the wall surface of the casing of the mobile terminal is disposed) to restrict the contact piece 110a from moving away from the contact piece 110b. Thereby, the contact piece 110a can be urged | biased more reliably to the contact piece 110b.

  FIG. 5 is a diagram illustrating an example of another shape of the contact fitting 100 including two contact pieces. As shown in FIGS. 5A to 5H, the present embodiment is applicable without being limited to the configuration described above.

  In the contact metal fitting 160 shown in FIG. 5 (a), a contact piece 160a having a loop shape is formed so as to be reversely rotated from the contact piece 110a. Thereby, the easy deformation direction of the loop shape can be directed to the other contact piece 160b. In addition, the other contact piece 160b forms a square portion 162 in place of the triangular portion, and an end thereof is abutted against the back side of the contact portion 164. Thus, even when a load is repeatedly applied to the square portion 162, the deformation can be prevented and the function as a rigid body can be exhibited.

  The contact fitting 166 shown in FIG. 5B has triangular portions 168a and 168b that can be regarded as rigid bodies at the tips of the two contact pieces 166a and 166b. Thereby, when one side urges the other, the triangular portions that can be regarded as rigid bodies come into contact with each other, so that the other contact piece can be reliably urged.

  As for the contact metal fitting 170 shown in FIG.5 (c), contact piece 170a, 170b is contacting the battery 140 by 1st folding | turning part 172a, 172b. Thereby, electric power can be received stably.

  A contact fitting 174 shown in FIG. 5D has a circular contact piece 174a and a contact piece 174b in which a triangular portion 176 that can be regarded as a rigid body is formed at the end of the loop shape. Thereby, even if the contact piece is deformed outward (rightward and leftward in the figure), it can be reliably brought into contact with the battery 140.

  A contact fitting 178 shown in FIG. 5 (e) is formed of a diamond-shaped contact piece 178a and a pin-shaped contact piece 178b. When the size of the contact metal fitting 100 is limited, the present embodiment can be applied even if the pin-type contact piece 178b is used.

  In the contact fitting 180 shown in FIG. 5 (f), a fitting portion 182 (unevenness) is formed at a location where the contact piece 180a and the contact piece 180b are in contact with each other. Thereby, another contact piece can be urged | biased reliably.

  In addition, as shown in FIG.5 (g), you may form the fitting part 186 in the contact pieces 184a and 184b of the same shape from which elasticity differs. Accordingly, even when force is simultaneously applied in the separation direction, the contact piece having low elasticity is preferentially deformed and the other contact piece is reliably urged, so that the contact with the battery can be maintained. Since it is not necessary to form contact pieces having different shapes, the cost can be reduced.

  The contact fitting 188 shown in FIG. 5 (h) includes a contact piece 188a in which the contact portion 190a is formed on an arc, and a contact piece 188b in which the first folded portion 192 becomes the contact portion 190b and is in contact with the battery 140. Is formed. As a result, when the contact piece 188b in contact with the battery is deformed in the separation direction in the first folded portion 192, the contact piece 188a formed with the contact portion 190a on the arc is pushed up in the contact direction, It is deformed by the urging force and can be brought into contact with the battery 140 on the surface.

  As described above, according to the present embodiment, any one of the contact pieces 110a and 110b can be brought into contact with the electrode to suppress the occurrence of instantaneous interruption of the electronic device, so that the capacity of the capacitor can be reduced or the instantaneous interruption return circuit can be omitted. Therefore, the mounting area can be reduced and the cost can be reduced. In addition, since the contact metal fitting 100 is formed of a single sheet metal, the shape of the contact metal fitting 100 is not larger than that of a conventional connector component, and the cost is not increased.

  FIG. 6 is a diagram illustrating an example in which the contact fitting according to the first embodiment is applied to a portable electronic device. Note that description and illustration of other structures of the mobile phone 300 that are well known to those skilled in the art are omitted.

  On the back side of the mobile phone 300, a battery housing recess 350 capable of detachably housing the battery 340 is formed. The battery storage recess 350 is a rectangular parallelepiped recess capable of storing, for example, a thin rectangular parallelepiped battery 340. Further, a contact fitting 100 that receives power from the + power terminal 342, the control terminal 344, and the −power terminal 346 of the battery 340 is provided on the side wall of the battery housing recess 350.

  In order to hold the battery 340 in the battery housing recess 350, locking grooves 352 and hooks 356 are formed at both ends of the battery housing recess 350. Further, a locking claw 354 and a hook fitting portion 358 are formed at both ends of the battery 340.

  With such a configuration, displacement of the battery 340 due to vibration or impact is prevented, and the contact with the contact fitting 100 is maintained. However, due to the dimensional tolerance (alignment) between the locking claw 354 and the hook fitting portion 358, the battery 340 may be slightly displaced due to an impact such as dropping. In this case, even if the battery 340 pushes the contact fitting 100 in the separating direction, the connection between the contact fitting 100 and the battery 340 is maintained by configuring the contact fitting 100 as described above. In addition, even when deformation in the separation direction is caused by an impact load applied to the contact fitting 100 itself, the connection with the battery 340 is maintained as described above.

  As described above, according to the present embodiment, it is possible to suppress the occurrence of instantaneous interruption of the portable electronic device by improving the vibration and impact resistance, and therefore it is possible to reduce the capacity of the capacitor or omit the instantaneous interruption return circuit. Therefore, the mobile terminal can be reduced in size and price. In addition, since no instantaneous interruption occurs, the portable terminal can be highly reliable for the user.

(Second Embodiment)
A second embodiment of the contact fitting according to the present embodiment will be described. Although the said 1st Embodiment demonstrated the example provided with two contact pieces, the 2nd Embodiment demonstrates the example provided with three contact pieces.

  FIG. 7 is a diagram showing the shape of the contact fitting 200 according to the second embodiment and the direction in which the three contact pieces 210a, 210b, and 210c are easily deformed. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  The contact metal fitting 200 is formed of a single sheet metal and includes a contact piece 210a, a contact piece 210b, a contact piece 210c, a flat portion 230a, a flat portion 230c, and the other end connecting portion 132. The contact pieces 210a, 210b, and 210c are connected to the other end connecting portion 132 through the flat portions 230a and 230c. The flat portions 230a and 230c may be appropriately changed in shape according to the mounting location of the contact metal fitting 200 (may not be flat).

  The contact pieces 210a and 210c have the same loop shape as the contact piece 110a described in the first embodiment. The contact piece 210c has the same loop shape as the contact piece 210a, but is arranged in mirror symmetry with the contact piece 210a with respect to the contact piece 210b. Therefore, the contact piece 210a and the contact piece 210c exhibit the same behavior and can be easily deformed in the separation direction. And when it deform | transforms in a separation direction, a width | variety will spread so that it may collapse, and the contact piece 210b is urged | biased from both sides.

  Specific examples of shapes of the contact pieces 210a and 210c include base portions 212a and 212c, first folded portions 214a and 214c, second folded portions 216a and 216c, and third folded portions 218a and 218c.

  The contact piece 210b is formed in a C shape having a cut in the contact direction, and includes a C-shaped portion 224 and connecting portions 226a and 226c. The contact piece 210b has a double structure folded back at the tip in the contact direction, and has high rigidity in the separation direction, but has low rigidity in the lateral direction (direction perpendicular to the separation direction) and is easily deformable. It has become. Therefore, the contact piece 210b is deformed so as to be crushed by the force urged by the contact pieces 210a and 210c and extends in the contact direction.

  As an example of a specific shape of the contact piece 210b, the contact piece 222b and 222c which are the tips of the connecting portions 226a and 226c are brought into contact with the battery 140. The contact pieces 210a and 210c come into contact with the battery 140 at contact portions 222a and 222d that are intersections of the base portions 212a and 212c and the first folded portions 214a and 214c. The current from the battery 140 is transmitted to the other end connecting portion 132 and is conducted to other circuits.

  Note that the contact pieces 210a and 210c are disposed so as to protrude toward the battery 140 from the contact piece 210b. This is because the contact piece 210b has high rigidity in the separation direction, so that it is difficult to attach the battery 140 when the contact piece 210b comes into contact with the battery 140 first.

  FIG. 8 is a diagram for explaining the deformation of the contact fitting 200 according to the second embodiment. FIG. 8A shows a case where the contact pieces 210a and 210c are deformed in the separating direction. (B) has shown the case where the contact piece 210b is deform | transforming in the separation direction.

  As shown in FIG. 8A, when the contact pieces 210a and 210c are deformed in the separation direction, the width increases, and the contact piece 210b is urged from the lateral direction and expanded in the contact direction. Deform.

  The extended contact piece 210b is deformed so as to be shortened in the separation direction due to the reaction, but as shown in FIG. 8B, the contact piece 210b is deformed so as to widen when shortened, and the contact piece 210a and the contact piece 210c are attached. To force. The contact pieces 210a and 210c are deformed by being urged by the contact piece 210b from the lateral direction and extend in the contact direction, and also extend in the contact direction by their own reaction.

  With this configuration, the contact metal fitting 200 instantaneously and alternately repeats the states of FIG. 8A and FIG. 8B when vibration or impact occurs. As a result, any of the contact piece 210b having a C-shape and the contact pieces 210a and 210c having a loop shape are brought into contact with the electrode, and occurrence of instantaneous interruption of the electronic device can be suppressed.

  As described above, according to the present embodiment, it is possible to suppress the occurrence of instantaneous interruption of the electronic device, reduce the capacitance of the capacitor, or omit the instantaneous interruption recovery circuit, thereby reducing the mounting area and the cost. Can be planned. In addition, since the contact metal fitting 200 is formed of a single sheet metal, the shape of the contact metal fitting 200 is not larger than that of a conventional connector part, and the cost is not increased.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  The present invention can be used as a contact fitting and a portable electronic device including the contact fitting. Furthermore, the present invention can also be used in portable electronic devices having a sliding contact structure, a pluggable contact structure, and a movable contact structure.
