2. Description of the Related Art In electronic equipment such as office automation equipment and communication equipment,
The use of memory cards is widespread. This memory card has a connector (card connector) installed in the electronic device.
When it is inserted into the electronic device, the electronic device is connected to the circuit.

In this card connector, the stored contents of the card may be destroyed by the electric charge accumulated in the connector. This problem tends to occur when the card is inserted into the connector in the state where there is a difference in electrostatic potential between the card and the circuit of the electronic device.

Therefore, conventionally, terminals for preventing electrostatic accidents are 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 ground of the circuit of the electronic device are made to have the same potential before the electrical contacts of the card and the terminals of the connector come into contact with each other. This prevents static electricity accidents in the circuit including the card.

Japanese Patent No. 2899947, Japanese Patent Laid-Open No. 8-
Japanese Patent No. 88059 discloses a technology of a card connector provided with such a terminal for countermeasure against electrostatic accident. In the former connector with a ground terminal, there is described a technique provided with a ground terminal having the same shape on the front and back sides for discharging static electricity charged on the surface of the card to the connector mounting board.
In the latter connector for a memory card, a ground metal fitting including a contact piece that contacts the front surface or the 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 is attached to the component. Techniques with reduced points are described.

On the other hand, Japanese Patent No. 3086209 discloses that
In order to prevent abrasion and damage of each terminal on the connector side and contacts on the card side, there is disclosed a technique in which a cover for mounting a card is configured to be openable.

At the offset position away from B, the contact portion 25 of each terminal T separates from the contact conductor of the circuit board CB. By doing so, it is considered that the electrical connection between each terminal T and the circuit board CB is released.

Between the housing H and the shell S, the shell S
Is provided with a stopper 15 for restricting the free end of the wrench from rotating beyond the offset position. This stopper 15
As shown in FIG. 5B, is composed of a protrusion protruding from the upper portion of the side wall of the housing H. This is because the opening angle of the shell S can always be kept constant by the stopper 15.

Each terminal T has a ground terminal T1 for grounding and a signal terminal T2 serving as a signal path.
And a detection terminal T3 for detecting opening / closing of the shell S and the like. For these three types of terminals, as shown in FIG.

The interval between the apex x and the tip z of the contact 30 of the card C is indicated by β3.

In this embodiment, α1, α2, and α3 are configured to satisfy the relationship of α1 <α2 <α3. Further, β1, β2, and β3 are β1 <
It is configured to satisfy the relationship of β2 <β3.

With this configuration, the ground terminal T1 first contacts the corresponding contact 30 of the card C while the shell S having the card C inserted therein is being 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 and 9 and the ground terminals T1 and T1 is released. At this time, the spring pieces 9, 9 come into contact with the surface of the card C.

The distance γ between the apex x of each terminal and the inner surface of the shell S when the card C is not inserted is determined by the thickness of the tip of the card C (the surface of the card C and the contact 30).
It is formed to be smaller than the thickness d) (FIG. 10 (b).
reference)). As a result, each terminal T1, T2, T3
The contact portion 25 of each terminal is surely brought into contact with the contact conductor of the circuit board CB at the set position where the contact is brought into contact with the corresponding contact 30 of the card C.

In the shell S, a card erroneous insertion preventing portion 50 for restricting entry of the card C when the card is erroneously inserted into the shell

The other is reverse insertion on both sides.

As a concrete structure for preventing these erroneous insertions, the groove widths of the card guide portions 5, 5 are changed in the middle. That is, in the middle of the card guide portions 5 and 5 (near the end), the narrow groove guide portions 5a (only one of which is shown) constituting the card erroneous insertion prevention portion 50 are provided. The narrow groove guide portion 5a has a groove width that prevents the card C guided along the card guide portion 5 from further entering. The narrow groove guide portion 5a is provided at a position before the end portion of the card C reaches each terminal of the housing H.

A slot 5b is provided between the narrow groove guide portion 5a and the card guide portion 5. As a result, when the card C is erroneously inserted, a part C1 of the tip of the card C projects from the slot 5b when the tip of the card C reaches the slot 5b. Therefore, the card erroneous insertion prevention 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. In FIG.
It shows an example in which the card C is inserted into the shell S upside down.

On both sides of the housing H, flanges 16 and 16 having screw holes 16a are provided. The housing H is fixed to the circuit board CB by a screw 17 which is passed through the screw hole 16a. The flange 16 is provided immediately below the arm portion 6 of the shell S. Further, as shown in FIG. 1, when the screw 17 is screwed into the circuit board CB, the head 17 a of the screw 17 is set to be positioned outside the arm 6. Moreover, the head portion 17a and the arm portion 6 are designed so as to be extremely close to or in contact with each other.

For example, the distance between the head portion 17a and the arm portion 6 is set to be smaller than the length of the shaft pin 8. Thus, it is ensured that the pin hole 7 of the arm portion 6 and the shaft pin 8 are maintained in a coupled state. Therefore,
In this embodiment, the hinge portion 2 includes a shaft pin 8 projecting from the side surface of the housing H, an arm portion 6 projecting from the shell S and having a pin hole 7 through which the shaft pin 8 penetrates, and the housing H on the circuit board CB. Head 17a of screw 17 fixed to
The configuration includes and.

Further, the head portion 17a also serves as a stopper portion for preventing the arm portion 6 from coming off the shaft pin 8. According to this structure, the hinge part 2 can be easily assembled, and the head part 17a of the screw 17 protects the function of the hinge part 2.

According to this embodiment, the spring pieces 9, 9 provided on the shell S come into contact with the terminals T1, T1 on both sides, respectively, to keep the distance between the free end of the shell S and the housing H constant. . Spring pieces 9 and 9 are terminals T
By making contact with 1, T1, both the repulsive force of the spring piece 9 and the repulsive force of the terminal T1 can be made to function, and the distance between the free end of the shell S and the housing H can be kept constant.

Further, the terminal T1 with which the spring piece 9 contacts
If is used as the ground terminal, the electrostatic accident prevention function of the card C can be surely and effectively exhibited.
Further, by rotating the free end of the shell S about the hinge portion 2, each terminal T1, T2, T of the connector C is rotated.
3 and the contact 30 of the card C come into contact with each other. As a result, the durability of the contact portion can be improved. That is, since the contact 30 of the card C contacts the terminals T1, T2, T3 of the connector by pressing it from above, the card C is inserted from the horizontal direction with the board CB as in the conventional case, and the contact of the card C and the connector are inserted. Contacts do not rub against each other.

The free end of the shell S is rotatable between a set position corresponding to the mounting position of the card C and an offset position corresponding to the insertion / removal position of the card C. By doing so, the rotation range of the shell S can be limited to the minimum range required for setting and offsetting the card C. This facilitates downsizing and compactification of the card connector 1.

Further, by forming the spring piece 9 by a cut-and-raised piece from the shell S, it is possible to simplify the structure and manufacture thereof 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.

By using the ground terminal T1 as the terminal that contacts the spring piece 9, the shell S can be kept in contact with the ground terminal T1 via the spring piece 9 at all times. As a result, the shell S can always have the same potential as the ground terminal T1.

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 in which the card C is inserted is in the set position. Thus, the terminals can be electrically connected to the circuit board 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 electrically connecting the terminal and the circuit board, the inspection work of the soldering place, etc. are unnecessary.

Further, since the stopper 15 for restricting the free end of the shell S from rotating beyond the offset position is provided between the housing H and the shell S, the opening angle of the shell S is always kept constant. can do.

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, and the base end portions 21 are provided with lances 24 for preventing the mounting holes 11a from coming off. It is provided. As a result, the function of preventing each terminal T from coming off the housing H can be significantly improved.

On the other hand, according to the card connector of this embodiment, the plurality of terminals sequentially come into contact with the contacts 30 of the card C during the rotation of the card from the offset position to the set position. It is possible to set the order of contact with and.

Regarding each terminal T, after the spring piece 9 first makes contact with the ground terminal T1, the card C
It is desirable that the contact 30 of the contact the signal terminal T2. With this configuration, the signal terminal T
2 can be prevented from contacting the contact 30 of the card C before the ground terminal T1.

It is desirable that each terminal T is 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.
