Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel connector, in particular a connector which itself has a ζ-two switch mechanism, and also relates to a cartridge type circuit board to which this connector is connected.

Conventionally, cartridge-type circuit boards that can be easily replaced and expanded have been used as memory replacement and memory expansion devices for microcomputers and the like, and these circuit boards include ICIs as shown in the two ζ lines in Figure 1. It is composed of a circuit board 2, an insulating case 3, and a connector 4.
The connector 4 used here is case 3
It is fixed to the case 3 with a stopper 5 to prevent it from floating in the case 3, and one end of its conductive surface is brought into contact with the circuit board 2 [2], and the other end 6 is protruded from the opening of the case 3. Then, push this cartridge-type circuit board into a predetermined position C; this connector 4 will be held in contact with the external electrode 7, and the connector 4 will be held in contact with the external electrode 7. The ICI used in this type of circuit board is high density, low power consumption, simple manufacturing process, and low cost, so MO8 type IC is widely used. However, this MO8 type C is prone to voltage breakdown, and when the internal circuit board 2 and connector 4 are in the connected state C2 before the cartridge is installed, the connector 4 protruding from the insulating case 3 If the other end protrusion 6 is touched by a human body charged with static electricity, it may be damaged. It is necessary to take measures such as prevention, which makes handling inconvenient and limits the scope of application.

The present invention relates to a connector that solves such disadvantages, and a cartridge type circuit board including this connector, which has a flexible flange portion protruding from the flat side portion C of the connector conductive portion. The present invention relates to a cartridge-type circuit board in which the connector is connected to a circuit board containing an MO8 type IC via a flange portion thereof.

Improvements to cartridge-type circuit boards, including type XC We focused on the fact that this connector should be connected to the circuit board when it is inserted into the circuit as an expansion cartridge, and as a result of repeated studies on this configuration, we found that this connector could be connected to the flat side of the conductive part. This purpose can be easily achieved by using a protruding flange section that allows variable pressure.C:
After discovering that this could be achieved, the present invention was completed by devising the structure, shape, etc. of this variable flange portion.

Next, to explain this based on the attached drawings, the second
The figure shows an example of the connector (2) of the present invention, but the connector part 12 may be anisotropic as long as it has anisotropy that allows conduction in the pressure contact direction, and this means that the conductor wiring is between the opposing electrodes. They may have a 1:1 correspondence or may be connected in large numbers. In addition, this connector consists of a matrix consisting of an insulating polymer material such as engineering plastic or synthetic rubber, metal with anti-rust treatment, carbon, or a polymer compound containing a conductivity imparting agent. It may be a combination of conductive materials made of materials such as the like, but at least one of them should be made of a rubber-like elastic material in order to increase contact stability and absorb unevenness of the electrode part. It is preferable. The variable flange 13 attached to this connector 12 is C2, as shown in FIG.
In order not to obstruct the conduction of the connector 12, the connector 12 is provided on the side of the plane that includes the conduction part in a state that protrudes from the plane.
C2 is deformed and retracted to at least the head end face f2 of this connector (17).

Therefore, it is preferable that the variable flange portion 13 be made of a material that can be deformed with a relatively small pressure, such as various types of plastics or rubber. It is preferable to use silicone rubber. The shape and size of this variable flange portion 13 are arbitrary, and it is usually a rectangular parallelepiped that doubles as shown in FIG. However, this also deforms with a smaller pressing force so that C1 (b), (cl, (dJ
(It may be L-shaped, L-shaped, or triangular in shape, such as two.Also, the protrusion of this variable flange from the plane of the connector conduction part will not deform even if it is lightly touched, but when connecting the connector. ≦Since Yu is required to be deformed with a small pressing force, from this point of view, 0.2 to 2
As mentioned above, it is preferable that this variable flange part is made of a rubber-like elastic body, but the hardness is set so that the connector will not be deformed by the pressing force used to deform it. In order to achieve this, the hardness is preferably about 10 degrees or more smaller than the hardness of the connector 12 itself.

The connector (■) of the present invention has a C2 configuration as described above,
This is said to have a kind of switch mechanism due to the presence of the variable flange portion, and is therefore useful for, for example, the above-mentioned cartridge type circuit main board.

FIG. 3 shows a cartridge-type circuit board incorporating this connector U, and shows the circuit board 22 connected to the MO8 type IC 21 [2] The variable flange portion 23 is shown at the side C of the plane of the conductive portion: A connector 24 protruding from the plane is connected via the variable flange portion 23, and these are housed in an insulating case 25. In this case, the other end 26 of the connector 24 protrudes from the insulating case 25, but since the conductive part of the connector 24 is electrically connected to the circuit board, the other end 26 may be masked or protected against static electricity. No special equipment is required. In addition, when this cartridge type circuit board is to be incorporated into a microcomputer or the like, the other end 26 is suppressed 2, thereby deforming the variable flap register part 2, and at least connecting it to the conduction of the connector head. If the cartridge is retracted to the flat surface, this conductive part will be connected to the circuit board, so if the cartridge is assembled in this state, the intended purpose can be easily achieved. In addition, when assembling the +1 joint (in this car), insert it into the memory storage section of the microcomputer without pressing the variable flange part in advance, and then connect the external electrode to the other end (26). Alternatively, the variable flange portion may be pressed by the variable flange portion, and this provides the advantage that operations such as replacement and expansion of the molten metal can be easily performed using the switch mechanism of the variable flange portion.

Note that FIGS. 4 to 7 show the connector 24 according to the present invention.
This is an example of a method of pressure-contacting and inserting a cartridge-type circuit board 30 incorporating a cartridge into a storage section of an electronic device, and the fourth
The figure is a plan view, Figure 5 1 is a front view, Figure 6 is a side view,
FIG. 7 is a perspective view showing this mechanism. In the figure, a cartridge-type circuit board 30 housing a connector 24 is inserted into an external device 31 from above and stored, but this external device 31 is provided with a slide case 32 and a slide case guide 33. 32 (2) is equipped with a hinge 34. In order to bring the circuit board inside this cartridge into contact with the connector, it is sufficient to slide this slide case 32 to the right (2). Since the hinge 10 is guided by the slide guide 9, the slide case 32 and the circuit board 30 are pressed downward, and this causes the variable flange attached to the connector 24 to deform, and the connector 24 and the circuit board are brought into contact with each other to complete this assembly.
