- the switch 18 is composed of a female switch 18a and a female switch 18b.
- the switch 18a is provided with a spiral contact 18c having the same configuration as the above-mentioned spiral contact, and the spiral contact 18c is connected to a power supply (not shown). ing.
- the switch 18b is provided with a connection terminal 7 connected to an electronic component (equipment) not shown, for example, the above-mentioned spherical connection terminal.
- the switch 18b when the switch 18b is moved in the direction indicated by the arrow in the figure, the connection terminal 7 provided on the switch 18b comes into contact with the spiral contact 18c, and the power supply (not shown) and the power supply (not shown) An electronic component is connected. In other words, the switch is turned ON and power is supplied to the electronic components (equipment).
- the spiral contactor according to the present invention is manufactured using the micromachining technology, so that the switch manufactured using the spiral contactor according to the present invention is a thin and small switch. be able to.
- the thickness t2 of the female switch 18b and the thickness t1 of the female switch 18a is the total thickness t of the credit card (0. 7 mm).
- the spiral contactor according to the present invention can be suitably used as a switch used for various nanodepises.
- the female switch 19a or the female switch 19b May be configured to rotate about the fulcrum 19c.
- FIGS. 9 (a) to 9 (c) are diagrams showing other examples in which the spiral contactor according to the present invention is applied to a switch 50 such as an electronic component.
- FIG. 10 (a) is a diagram schematically showing FIG. 9 (a)
- FIG. 10 (b) is a schematic cross section taken along line D-D of FIG. 10 (a).
- FIG. 10 (a) is a diagram schematically showing FIG. 9 (a)
- FIG. 10 (b) is a schematic cross section taken along line D-D of FIG. 10 (a).
- this switch is composed of a switch 50a and a female switch 50b.
- the switch 50a is provided with connection terminals 51a and 51b that are not electrically connected.
- a spiral contact 40 is provided on the female switch 5 Ob.
- the spiral contact 40 is provided with a contact 41 and a contact 42 (see FIGS. 10 (a) and 10 (b)).
- the contact 41 has a spiral shape as in the case of the contact portion 1 described above, and the thickness of the contact 41 is set so as to become thinner toward the distal end side.
- the base end R of the contact 41 is fixed to the outer peripheral frame T of the spiral contact 40, and the contact 41 spirally moves upward from the base end R which is a connection point with the outer peripheral frame T. It is provided in an extended state. That is, as shown in FIG. 10 (b), in the contact 41, the point m is located at the lowermost position, and gradually moves upward as it goes to the points 1 and h. I have.
- the contact 42 is fixed to the substrate at an end i thereof, and is provided in a state of extending upward from the end i in a spiral. That is, as shown in FIG. 10 (b), in the contact 42, the point i is located at the lowest position, and then gradually moves upward as the position proceeds to the points k and j. ing. That is, the spiral contact 40 is provided with a contact 42 having a large spiral radius and a contact 41 having a small spiral radius, that is, a total of two contacts. Then, when pressed by the contact terminals 51a and 51b from the upper side, the contacts 40 and 41 move downward. It is configured to be able to move.
- the switch 50 having such a configuration employs a contactor that is extremely small and has two electric paths. Therefore, the switch used for the seed nanodepice and the probe part of a semiconductor chip inspection device are used. Can also be suitably used.
- the present invention can be variously modified and changed within the scope of the technical concept.
- the present invention is characterized by performing fine processing by photolithography technology and plating manufacturing technology, and it naturally extends to manufacturing methods using this technology.
- the contactor for spiral contactors which concerns on this invention, it can contact reliably with the connection terminal of various electronic components whose microminiaturization progresses, and can ensure the electrical connection with an electronic component.
