In this case, if the ninth figure Z (10) is in contact with the predetermined circuit electrode (P1), the magazine of the contact (1) is contracted by the amount of movement of the inspection jig (1), and the inspection side end (heart) is reduced. The electrode (P1) is in contact. At this time, press the winding part. By inspecting the side end portion (10) and the gauge s contact 'to become the circuit board (8) of the circuit board (7) * the hair electrode (6) is turned on by the contact (2), so that the second board (7) can be inspected (the main effect of the embodiment) As described above, the inspection jig (1) and the contact (2) are configured to have the following form: 201044698. In the form involving the money, the outline (2) consists of the root wire (9): the title 2 outer = single; Two = Total - S Touch (2) is a component with a total length of several tens of meters. Therefore, in the case of τ, as in the case of this configuration, it is necessary to make a fine i in the group scale. The assembly work of the f-contact (2) can reduce the number of assemblers and reduce the number of parts, thereby reducing the cost of components. Further, the wire member (13) is wound into a spiral shape by a contact member. Therefore, when the "money is formed into a linear shape" as compared with the case where the wire material = j is linear, it is easily plastically deformed. In contrast, the contact (2) has an inspection-side end portion (10) disposed at a long (Ρ) contact of the contact (2), with respect to the second side, and is disposed on the other end side, and inspected The electrode portion (5)' of the jig (1) and the main body portion (12) connecting the inspection-side end portion (1) and the clamp-side end, and the portion of the end hole (3). and,. This body id is a spring winding portion (22) of the spring portion. In the contact (2) thus constituted, the spring winding portion (22) has 乂 so that the circuit of the inspection side end portion (10) and the circuit board (7) is stretched, '=. Therefore, the inspection side end portion (1〇) can be electrically contacted with : . In addition, in the inspection-side end portion (1〇) of the contact (2), it has the property and state of the shrunken spring, and therefore is elastic along the roll|(). Therefore, the inspection side end portion (10) is curved in the left and right front and rear directions as in the +if direction. The result is that %2 makes ^ terminal ^ (= 201044698, obliquely touches the circuit electrode (ρι). CP〇^ΜΜ 5 ^^^^(rasist) P2 ^ is used inside the needle touch (P3). Therefore, for example, if the surface of the protective layer (the front end of the p2 is connected to the circuit electrode (P1) from the circuit electrode (P1) is slightly deviated, the contact S and the reel (L) cannot be made. ) It is wound into a bullet shape, so that it can be used for the front end portion (15). In this case, even in the case where the inspection side end portion (1〇) is connected, (10)) the direction w(1) of the contact is The circuit electrode (7) is connected to the center of (P1)m °, but even if the (p4) of the upper electrode (PI) (recess (P3)) is connected, the front end portion (15) and the edge portion electrode (8) are turned over. (2) Forward (6) and circuit ο This is also wound into a bullet shape in the ^====(9), because the angle can also be relative to the axis a) t, if. Therefore, 'the end side of the clamp (5) ((4) the material of the material (6) is in contact with the ground. Also, the end of the financial end of the miscellaneous contact (2), the 邛(22), the inspection side end (1〇) upwards: 1«; In noff ^ ), the wire (13) is wound such that its winding diameter becomes smaller toward the front end. 12 201044698 Therefore, it is possible to prevent the inspection side end portion (10) from being caught in the small straight through hole (as shown in the tenth figure above, there is the edge portion on the concave portion (8) side of the inspection side end portion (10) sheath (Ρ2) (P4 In the case where the guard (10) is bent in the right and left direction, the second movement is reduced, and since the center line and the winding diameter of the inspection side end portion (1G) are smaller toward the tip end, it is possible to prevent the opening of the diameter hole (17). In the case of the edge portion (17A), the card is wound in the small straight ο and is wound up to the front end of the winding diameter. Therefore, when the center wire (1) is attached to the receiving body (4), the opening edge of the body (7) can be prevented.

When the inspection portion (8) is moved to the side of the circuit board (8) by bringing the folded portion (8) into contact with the electrode, the magazine winding portion (22 is compressed, and the folded portion (51) is displaced upward. As described above, The maximum width W1 of the side J and the side portion (53) in the direction in which the reel (L) is sandwiched is set to the inner diameter M1 of the small-diameter hole (Γ7), so that the folded portion (51) can enter the receiving hole (3). Therefore, the upward displacement of the folded portion (51) is not hindered. Further, the contact (50), as shown in Fig. 17, the folded portion (55) is configured as a clamp side end portion, wherein The folded portion (55) is formed by folding the front end portion of the wire (13) on the side of the wire (13) forming the contact (5) from the front end side of the contact (5〇) toward the main body portion (12) side into a hook shape.
