Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a card connector for connecting a small and thin card-type device. In particular, the present invention relates to a connector technology that takes into account protection of each terminal mounted on a housing, countermeasures against static electricity, contact timing between a card and each terminal, and the like.
[0002]
[Prior art]
The use of memory cards is widespread in electronic devices such as OA devices and communication devices. The memory card is connected to a circuit of the electronic device by being inserted into a connector (card connector) provided in the electronic device.
[0003]
In this card connector, the stored contents of the card may be destroyed by the electric charge accumulated in the connector. This problem is likely to occur when the card is inserted into the connector with a difference in electrostatic potential between the card and the circuit of the electronic device.
[0004]
Therefore, conventionally, a terminal for countermeasures against static electricity accidents is provided on the connector side. This is a method in which when the card is inserted into the connector, the ground of the card and the circuit circuit of the electronic device are made to have the same potential before the electrical contact of the card and the terminal of the connector come into contact with each other. This prevents an electrostatic accident in the circuit including the card.
[0005]
Japanese Patent No. 2899947 and Japanese Patent Laid-Open No. 8-88059 describe a technique of a card connector provided with terminals for countermeasures against such electrostatic accidents. The former connector with a ground terminal describes a technique including a ground terminal having the same shape on the front and back sides for discharging static electricity charged on the card surface to the connector mounting board. In the latter memory card connector, by attaching a grounding fixture comprising a contact piece that contacts the front or back surface of the memory card, a contact piece that contacts the side surface of the memory card, and a contact piece that contacts the circuit terminal, A technique with a reduced score is described.
[0006]
On the other hand, Japanese Patent No. 3086209 discloses a technique in which a cover for mounting a card is configured to be openable and closable in order to prevent wear and damage of each terminal on the connector side and contacts on the card side.
[0007]
[Problems to be solved by the invention]
Among the card connectors, a multi-media card connector that has been attracting attention in recent years uses a smaller card including a memory stick having a length of about several centimeters. Therefore, in this type of card connector, in order to contribute to miniaturization and weight reduction of electronic devices (for example, mobile computers, digital cameras, portable digital video cameras, etc.) on which the card connector is mounted, further miniaturization of the card connector itself, And thinning is required.
[0008]
However, the conventional card connector has the following problems.
(1) The connector itself cannot sufficiently meet the demand for miniaturization and thinning.
(2) Terminals for countermeasures against static electricity accidents must be provided separately on the housing or shell.
(3) To make the shell openable and closable with respect to the housing, it is necessary to provide an opening / closing mechanism and a positioning mechanism between them, and the number of parts increases.
[0009]
Here, the problem (1) is related to the problem (2) and the problem (3). Regarding the problem (2), the number of parts of the connector increases, and it is difficult to reduce the size and thickness accordingly. Regarding the problem (3), although it is possible to prevent the terminal and contacts from being worn and damaged, the number of parts increases, making it difficult to reduce the size and thickness of the connector.
[0010]
On the other hand, in a conventional card connector, a method is generally adopted in which the tail portion of each terminal is soldered to a circuit board to achieve conduction between each terminal and the circuit board. However, in this method, it is necessary to inspect the soldered portion after the connector is mounted on the circuit board. This is because, for example, in the soldering method using the solder reflow technique, if there is variation (unevenness) at the tip of each terminal, a soldering failure may occur.
[0011]
The problem of the present invention is that the card's electrostatic accident prevention function can be effectively exhibited while meeting the needs for downsizing and thinning, and consideration is given to improving the durability of the contact area and improving the productivity of the connector. Is to provide a card connector.
[0012]
[Means for Solving the Problems]
The card connector of the present invention has an insulating housing having a plurality of terminals mounted thereon, one end and the other end, one end coupled to the housing via a hinge portion, and the other end centered on the hinge portion. A shell provided rotatably, a card insertion opening provided on the other end side of the shell for inserting a card into the shell, provided in the shell, and in contact with at least one of the terminals. And a spring piece for maintaining a constant distance between the other end of the shell and the housing.
[0013]
According to the present invention, the spring piece provided on the shell is in contact with at least one of the terminals to keep the distance between the other end of the shell and the housing constant. When the spring piece comes into contact with the terminal, both the repulsive force of the spring piece and the repulsive force of the terminal can function, and the distance between the other end of the shell and the housing can be kept constant. Further, if the terminal with which the spring piece contacts is a ground terminal, the card's electrostatic accident prevention function can be reliably and effectively exhibited. Further, the other end of the shell rotates around the hinge portion, so that the connector terminal and the card come into contact with each other. As a result, it is possible to consider improving the durability of the contact portion.
[0014]
The other end of the shell is preferably rotatable between a set position corresponding to the card mounting position and an offset position corresponding to the card insertion / removal position. By rotating the other end of the shell between the set position and the offset position, the rotation range of the shell can be limited to the minimum range necessary for setting and offset of the card. As a result, it becomes easy to reduce the size and size.
[0015]
Preferably, the shell is formed of a conductive metal plate, and the spring piece is formed of a cut and raised piece from the shell. By forming the spring pieces by cutting and raising pieces from the shell, the configuration and production can be simplified as compared with the case where the spring pieces are separate members.
[0016]
It is desirable that a plurality of the spring pieces are provided at intervals in the width direction of the shell. If comprised in this way, a shell can be reliably and stably supported by several spring pieces.
[0017]
Each terminal includes a ground terminal and a signal terminal, and the spring piece is preferably in contact with the ground terminal. If it does in this way, a shell can always be made to contact a ground terminal via a spring piece. As a result, the shell can always be at the same potential as the ground terminal.
[0018]
Each terminal is preferably provided with a contact portion that conducts to a circuit board on which the housing is mounted when the other end of the shell into which the card is inserted is in the set position. When comprised in this way, a terminal and a circuit board can be electrically connected by operation which inserts a card | curd in a shell, and operation which rotates the other end of a shell to a set position. Therefore, the soldering work for conducting the terminal and the circuit board and the inspection work for the soldered portion are not required.
[0019]
It is desirable that a stopper is provided between the housing and the shell to restrict the other end of the shell from rotating beyond the offset position. This is because the opening angle of the shell can always be kept constant by the stopper.
[0020]
The housing is provided with a plurality of mounting holes, the base end portions of the terminals are press-fitted into the mounting holes, respectively, and the base end portions are provided with lances for retaining the mounting holes. desirable. In this way, the function of preventing each terminal from being detached from the housing can be remarkably improved.
[0021]
On the other hand, a card connector according to the present invention has an insulating housing, one end coupled to the housing via a hinge portion, and the other end offset corresponding to a card insertion position and a card insertion / removal position. A shell provided so as to be rotatable between a position, a card insertion slot provided in the other end of the shell, and a card insertion slot for inserting a card into the shell; And a plurality of terminals that sequentially contact the card contacts while the other end of the shell is rotated from the offset position of the card to the set position.
[0022]
According to the present invention, since the plurality of terminals sequentially contact the card contacts while rotating from the offset position of the card to the set position, the order of contact between the terminals and the contacts can be set.
[0023]
Here, it is preferable that the shell is provided with a spring piece that contacts the ground terminal and holds the other end of the shell in the offset position. Further, it is desirable that the shell is formed of a conductive metal plate, and the spring piece is formed of a cut and raised piece from the shell.
[0024]
Each of the terminals includes a ground terminal, a signal terminal, and a detection terminal, and the contact of the card contacts the signal terminal after the spring piece first contacts the ground terminal. With this configuration, the signal terminal can be prevented from contacting the contact of the card before the ground terminal.
[0025]
Each terminal is preferably provided with a contact portion that conducts to a circuit board on which the housing is mounted when the other end of the shell into which the card is inserted is in the set position.
[0026]
It is desirable that a part of the shell protrudes into the shell, and that the shell is provided with a card misinsertion prevention unit that restricts card entry when a card is erroneously inserted into the shell. By providing a portion in which a part of the shell protrudes into the shell, it is possible to configure an erroneous card insertion preventing portion without using any special parts.
[0027]
The hinge portion includes a shaft pin protruding from a side surface of the housing, an arm portion protruding from the shell and having a pin hole through which the shaft pin passes, and a screw head for fixing the housing to the circuit board, The head portion can also be configured to serve as a stopper portion that prevents the arm portion from being detached from the shaft pin. If comprised in this way, the assembly of a hinge part can be made easy and it can be set as the structure which protects the function of a hinge part with the head of a screw | thread.
[0028]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment in which the present invention is applied to a connector for a memory card (memory stick) will be described. 1 and 2 are perspective views of a card connector according to an embodiment of the present invention. FIG. 3 is a perspective view of the inside of the card connector according to the embodiment.
[0029]
The card connector 1 is formed in a substantially rectangular shape as a whole. The card connector 1 includes a housing H, a shell S provided in the housing H, and a plurality of terminals T (T1 to T3) mounted in the housing H, as shown in FIGS. . The card connector 1 is mounted on the circuit board CB.
[0030]
The housing H is made of an insulating material such as synthetic resin. The shell S is formed by bending or pressing a conductive metal plate. Similarly, the terminal T is formed by bending or pressing a conductive metal plate.
[0031]
The shell S has one end and the other end, one end is coupled to the housing H via the hinge portion 2, and the other end is provided so as to be able to reciprocate around the hinge portion 2. The other end of the shell S (hereinafter referred to as a free end) is provided with a card insertion slot 3 for inserting a card C into the shell S. The card insertion slot 3 is formed by an opening on the free end side of the shell S.
[0032]
The shell S includes a flat top plate portion 4, card guide portions 5 and 5 on both sides formed in a groove shape, and a pair of left and right arm portions 6 and 6 provided on one end side of the shell S. The arm portions 6 and 6 are provided so as to protrude from one end side of the shell S.
[0033]
Pin holes 7 (see FIG. 5B) are provided near the ends of the arm portions 6 and 6, respectively. The housing H is provided with shaft pins (bosses) 8 that are respectively inserted into the pin holes 7. Therefore, the hinge part 2 is composed of the shaft pin 8 and the arm part 6 having the pin hole 7. Of course, the pin hole 7 can be provided in the housing H, and the shaft pin 8 can be provided in the arm portion 6.
[0034]
The shell S is provided with spring pieces 9 and 9 for maintaining a constant distance between the free end of the shell S (the card insertion slot 3) and the housing H. The spring piece 9 is formed by cutting and raising the top plate portion 4 of the shell S. Two spring pieces 9 are formed on the left and right sides (in the width direction of the shell) at intervals.
[0035]
The two spring pieces 9 are in contact with the corresponding terminals T. In the example shown in FIG. 3, ten terminals T are mounted on the housing H. Among these terminals, the spring pieces 9, 9 are configured to contact the terminals T1, T1 located on both sides, respectively. Terminals T1, T1 located on both sides correspond to the ground terminal.
[0036]
The housing H is formed with a shorter length L than the shell S. The housing H includes a bottom plate 10, a front wall 11, and left and right side walls 12 and 12, and the whole is integrally formed of synthetic resin. The front wall 11 of the housing H is provided with a plurality of mounting holes 11a. Each terminal T is attached to the housing H by the base end portion 21 of each terminal T (T1, T2, T3) being press-fitted into the attachment hole 11a.
[0037]
As shown in FIG. 4C, the terminal T has a shape obtained by bending a thin strip material. Specifically, the terminal T is provided with elasticity by the terminal main body 20 extending along the bottom plate 10 of the housing H, the base end portion 21 provided on one end side of the terminal main body 20, and the front end being folded back. And a contact piece 22. The contact piece 22 is inclined so as to increase toward the base end 21 side.
[0038]
The base end portion 21 is a portion that is press-fitted into the mounting hole 11 a of the housing H. Each mounting hole 11 a is provided in the upper part of the front wall 11. Therefore, a rising portion 23 is formed between the base end portion 21 and the terminal main body 20 to adjust the height gap therebetween. The base end portion 21 is provided with a retaining lance 24 that functions when the base end portion 21 is press-fitted into the mounting hole 11a.
[0039]
The terminal body 20 of each terminal T is provided with a contact portion 25 for the circuit board CB. A part of the terminal body 20 is bent into a V shape, whereby the contact portion 25 is formed integrally with the terminal body 20. The contact portion 25 is provided directly below the contact piece 22.
[0040]
The bottom plate 10 of the housing H is provided with slits 14 at positions corresponding to the terminals T. The number of slits 14 corresponds to the number of terminals. The width of each slit 14 is slightly larger than the width of the terminal T. Thereby, it is set as the structure which the contact part 25 of each terminal T can pass through the corresponding slit 14, and can be displaced to the circuit board CB side.
[0041]
The free end of the shell S is rotated between a set position (see FIG. 10C) corresponding to the card C mounting position and an offset position (see FIG. 10A) corresponding to the card C insertion / extraction position. It is configured to be movable. The setting position of the card C corresponds to a state where the card C inserted into the shell S is substantially parallel to the circuit board CB. The offset position of the card C corresponds to a state where the free end of the shell S is separated from the circuit board CB and the shell S is inclined. At this offset position, the card C can be freely inserted into and removed from the shell S.
[0042]
In this card connector 1, as shown in FIGS. 1 and 10 (c), when the card C is inserted into the shell S and the shell S is rotated to the set position of the card C, the contact portion of each terminal T 25 is configured to contact the circuit board CB. On the surface of the circuit board CB, contact conductors (not shown) such as solder bumps are provided at positions corresponding to the contact portions 25. Thereby, consideration is given to ensuring electrical connection between each terminal T and the circuit board CB.
[0043]
The conduction between the card C and the terminal T is performed when the contact piece 22 of the terminal T contacts the contact 30 of the card C. At the offset position where the free end of the shell S is separated from the circuit board CB, the contact portion 25 of each terminal T is separated from the contact conductor of the circuit board CB. Thus, consideration is given to releasing the electrical connection between each terminal T and the circuit board CB.
[0044]
A stopper 15 is provided between the housing H and the shell S to restrict the free end of the shell S from rotating beyond the offset position. As shown in FIG. 5B, the stopper 15 is constituted by a protrusion that protrudes from the upper part of the side wall of the housing H. This is because the opening angle of the shell S can be always kept constant by the stopper 15.
[0045]
Each terminal T is classified into a ground terminal T1 for earthing, a signal terminal T2 serving as a signal path, and a detection terminal T3 for detecting opening and closing of the shell S and the like. For these three types of terminals, as shown in FIG. 3, from the direction of arrow A, the first and tenth terminals T1 are ground terminals, the sixth terminal T3 is a detection terminal, and the remaining terminal T2 is a signal terminal. Designed to be available.
[0046]
The three types of terminals T1, T2, and T3 are configured to have different timings for contacting the contact portion 30 of the card C as shown in FIG. That is, the three types of terminals T1, T2, and T3 sequentially contact the corresponding contacts 30 of the card C while the free end of the shell S into which the card C is inserted is rotated from the offset position of the card C to the set position. It is configured to do.
[0047]
FIG. 6A shows the configuration of the ground terminal T1. The distance between the apex x of the contact piece 22 of the ground terminal T1 and the back wall y extending downward from the top plate 4 of the shell S is denoted by α1. An interval between the vertex x and the tip z of the contact 30 of the card C is denoted by β1.
[0048]
FIG. 6B shows the configuration of the signal terminal T2. The distance between the apex x of the contact piece 22 of the signal terminal T2 and the back wall y extending downward from the top plate 4 of the shell S is denoted by α2. An interval between the vertex x and the tip z of the contact 30 of the card C is denoted by β2.
[0049]
FIG. 6C shows the configuration of the detection terminal T3. The distance between the apex x of the contact piece 22 of the detection terminal T3 and the back wall y extending downward from the top plate 4 of the shell S is denoted by α3. The interval between the vertex x and the tip z of the contact 30 of the card C is denoted by β3.
[0050]
In this embodiment, α1, α2, and α3 are configured to satisfy the relationship of α1 <α2 <α3. Furthermore, β1, β2, and β3 are configured to satisfy the relationship β1 <β2 <β3.
[0051]
With this configuration, the ground terminal T1 first contacts the corresponding contact 30 of the card C while the shell S in which the card C is inserted is rotated from the offset position to the set position. Next, the signal terminal T2 contacts the corresponding contact 30. Finally, the detection terminal T3 contacts the corresponding contact 30. When the card C is inserted into the shell S, the contact between the spring pieces 9, 9 and the ground terminals T1, T1 is released. At this time, the spring pieces 9 and 9 are in contact with the surface of the card C.
[0052]
When the card C is not inserted, the distance γ between the vertex x of each terminal and the inner surface of the shell S is larger than the thickness d of the tip of the card C (thickness between the surface of the card C and the contact 30) d. It is formed small (see FIG. 10B). Thereby, the contact portion 25 of each terminal is in contact with the contact conductor of the circuit board CB at the set position where each terminal T1, T2, T3 is in contact with the corresponding contact 30 of the card C. .
[0053]
The shell S is provided with a card misinsertion preventing unit 50 that restricts the entry of the card C when the card is erroneously inserted into the shell. The wrong card insertion preventing portion 50 is formed by a portion in which a part of the shell S protrudes into the shell. The configuration of the erroneous card insertion preventing portion 50 is shown in FIGS. The following two types of card insertion mistakes are mainly assumed. One is reverse insertion. The other is reverse insertion.
[0054]
As a specific configuration for preventing these erroneous insertions, the groove widths of the card guide portions 5 and 5 are changed in the middle. That is, a narrow groove guide portion 5a (only one is shown) constituting the card erroneous insertion preventing portion 50 is provided in the middle of the card guide portions 5 and 5 (near the end). The narrow groove guide portion 5a has a groove width that prevents the card C guided along the card guide portion 5 from entering further. The narrow groove guide portion 5 a is provided at a position before the end portion of the card C reaches each terminal of the housing H.
[0055]
A slot 5 b is provided between the narrow groove guide portion 5 a and the card guide portion 5. As a result, when the card C is erroneously inserted, a part C1 of the leading end of the card C protrudes from the slot 5b when the leading end of the card C reaches the slot 5b. Accordingly, the wrong card insertion preventing portion 50 is composed of the narrow groove guide portion 5a and the slot 5b. FIG. 7 shows an example in which the card C is inserted back and forth in the shell S. FIG. 8 shows an example in which the card C is inserted into the shell S upside down.
[0056]
On both sides of the housing H, flanges 16 and 16 with screw holes 16a are provided. The housing H is fixed to the circuit board CB with screws 17 that pass through the screw holes 16a. The flange 16 is provided directly below the arm portion 6 of the shell S. Furthermore, as shown in FIG. 1, the head 17 a of the screw 17 is set to be positioned outside the arm portion 6 in a state where the screw 17 is screwed into the circuit board CB. In addition, consideration is given to the form in which the head portion 17a and the arm portion 6 are extremely close to or in contact with each other.
[0057]
For example, the distance between the head portion 17 a and the arm portion 6 is set to be smaller than the length of the shaft pin 8. Thus, consideration is given to maintaining the coupling state between the pin hole 7 of the arm portion 6 and the shaft pin 8. Therefore, in this embodiment, the hinge portion 2 is a circuit that connects the housing H with the shaft pin 8 projecting from the side surface of the housing H, the arm portion 6 projecting from the shell S and having the pin hole 7 through which the shaft pin 8 passes. And a head 17a of a screw 17 fixed to the substrate CB.
[0058]
Further, the head portion 17a also serves as a stopper portion that prevents the arm portion 6 from being detached from the shaft pin 8. If comprised in this way, it can be set as the structure which makes the assembly of the hinge part 2 easy and protects the function of the hinge part 2 with the head 17a of the screw | thread 17. FIG.
[0059]
According to this embodiment, the spring pieces 9, 9 provided on the shell S are in contact with the terminals T1, T1 on both sides, respectively, and the distance between the free end of the shell S and the housing H is kept constant. When the spring pieces 9 and 9 are in contact with the terminals T1 and T1, both the repulsive force of the spring piece 9 and the repulsive force of the terminal T1 function to keep the free end of the shell S and the housing H constant. can do.
[0060]
Further, if the terminal T1 with which the spring piece 9 comes into contact is a ground terminal, the electrostatic accident prevention function of the card C can be reliably and effectively exhibited. Further, the free end of the shell S rotates around the hinge portion 2 so that the terminals T1, T2, T3 of the connector C and the contact 30 of the card C come into contact with each other. As a result, it is possible to consider improving the durability of the contact portion. That is, since the contact 30 of the card C comes into contact with the terminals T1, T2, and T3 of the connector by pressing from above, the card C is inserted from the horizontal direction with respect to the substrate CB as in the prior art. There is no contact so as to rub the contacts.
[0061]
The free end of the shell S is rotatable between a set position corresponding to the card C mounting position and an offset position corresponding to the card C insertion / extraction position. In this way, the rotation range of the shell S can be limited to the minimum range necessary for setting and offset of the card C. As a result, the card connector 1 can be easily reduced in size and size.
[0062]
Moreover, by forming the spring piece 9 from a cut-and-raised piece from the shell S, the configuration and manufacture can be simplified as compared with the case where the spring piece 9 is a separate member. By providing a plurality of spring pieces 9 at intervals in the width direction of the shell S, the shell S can be reliably and stably supported by the plurality of spring pieces 9.
[0063]
Further, by setting the terminal in contact with the spring piece 9 to be the ground terminal T1, the shell S can be always in contact with the ground terminal T1 via the spring piece 9. As a result, the shell S can always be at the same potential as the ground terminal T1.
[0064]
Each terminal is provided with a contact portion 25 that conducts to the circuit board CB on which the housing H is mounted when the other end of the shell S into which the card C is inserted is in the set position. Thereby, each terminal and a circuit board can be conducted by the operation of inserting the card C into the shell S and the operation of rotating the free end of the shell S to the set position. Therefore, the soldering work for conducting the terminal and the circuit board and the inspection work for the soldered portion are not required.
[0065]
Further, by providing a stopper 15 that restricts the free end of the shell S from rotating beyond the offset position between the housing H and the shell S, the opening angle of the shell S can be kept constant at all times. it can.
[0066]
The housing H is provided with a plurality of mounting holes 11a, the base end portions 21 of the terminals T are press-fitted into the mounting holes 11a, respectively, and the base end portions 21 are provided with lances 24 for preventing the mounting holes 11a from coming off. Yes. As a result, the function of preventing each terminal T from being detached from the housing H can be remarkably improved.
[0067]
On the other hand, according to the card connector according to this embodiment, the plurality of terminals sequentially contact the contact 30 of the card C while rotating from the offset position of the card to the set position, so that the terminal T and the contact 30 contact each other. You can set the order to do.
[0068]
For each terminal T, it is desirable that the contact 30 of the card C contacts the signal terminal T2 after the spring piece 9 first contacts the ground terminal T1. With this configuration, it is possible to prevent the signal terminal T2 from contacting the contact 30 of the card C before the ground terminal T1.
[0069]
Each terminal T is preferably provided with a contact portion 25 that conducts to the circuit board CB on which the housing H is mounted when the free end of the shell S into which the card C is inserted is in the set position.
[0070]
