The second terminal receiving portion 120b is opened by moving to the fourth position side. Inside the shielding member 13 (on the movable member 11 side), a pair of shielding urging members 15 such as a compression coil spring that urges the shielding member 13 upward is disposed. The tip of the connecting member 12 protrudes outward from the position where the shielding member 13 is disposed, and the shielding member 13 biased by the shielding biasing member 15 exceeds the third position. It is the suppression part 122 which suppresses moving upwards.

The movable member 11 will be described in detail. FIG. 8 is a schematic external view showing an example of the external appearance of the movable member 11 used in the terminal attaching / detaching apparatus 1 described in the present application. FIG. 8A is a plan view, and FIG. 8B is a right side view. The movable member 11 is substantially J in which the lower ends of a columnar protrusion 110 and a columnar locking portion 111 having a shorter axial length than the protrusion 110 are connected by a plate-like connecting portion 112. It has a letter shape. In addition, the movable member 11 is formed near the lower end of the locking portion 111 so as to protrude toward the shielding member 13, and a pressing portion 113 for pressing the shielding member 13 downward is formed. As described above, the protruding portion 110 of the movable member 11 has the display portion 110a on the side surface. The locking portion 111 having a cylindrical shape has a tapered contact surface 111a that is inclined from the upper end to the side surface. The contact surface 111a is formed at a position where the terminal 2 inserted into the upper first terminal receiving portion 120a comes into contact.

The connecting member 12 will be described in detail. FIG. 9 is a schematic perspective view showing an example of the appearance of the connecting member 12 used in the terminal attaching / detaching apparatus 1 described in the present application. FIG. 10 is a schematic plan view showing an example of the appearance of the connection member 12 used in the terminal attachment / detachment device 1 described in the present application. FIG. 10 shows a state in which accessories such as the presser fitting 121 are removed from the connection member 12. The connection member 12 is formed of a conductor such as a metal material having a rectangular plate shape. The connecting member 12 has a through hole 123 having a circular shape in plan view in the vicinity of both ends in the longitudinal direction. When the terminal 2 is inserted into the terminal receiving portion 120, the inserted terminal 2 is superimposed on the connecting member 12, and the locking hole 21 of the terminal 2 and the through hole 123 of the connecting member 12 are in communication with each other. Then, the engaging member 111 of the movable member 11 is inserted into the engaging hole 21 of the terminal 2 and the through hole 123 of the connecting member 12 that are in the communication state, whereby the movable member 11 engages the terminal 2. Further, as described above, both short sides of the connecting member 12 having a rectangular shape serve as a suppressing portion 122 that suppresses the rising of the shielding member 13. Furthermore, a curved portion 124 that is curved so as to be recessed inward is formed on both long sides of the connecting member 12 having a rectangular shape. Since the curved portions 124 are alternately formed at positions where the long sides do not face each other, the connecting member 12 is curved in a substantially S shape as a whole. In addition, each curved part 124 formed in the position where both long sides do not oppose corresponds to the position of the projecting part 110 of the movable member 11, and is formed so that the connecting member 12 does not contact the projecting part 110. Yes. In other words, the connecting member 12 connects the terminals 2 inserted from both the left and right sides in a straight line and has a sufficient width, thereby having a sufficient power transmission performance. In addition, the connecting member 12 forms the curved portion 124 at a position where the long sides do not oppose each other, thereby ensuring a sufficient width, but without increasing the arrangement interval of the movable member 11, as the entire terminal attaching / detaching device 1. The miniaturization is realized. The upper and lower presser fittings 121 are formed in substantially the same shape as the connection member 12, a hole corresponding to the through hole 123 of the connection member 12 is opened, and a position corresponding to the bending portion 124 of the connection member 12 is curved. doing. However, the presser fitting 121 is formed so that the length in the long side direction is shorter than that of the connection member 12, and the shielding member 13 is not in contact.

The structure of the shielding member 13 and the operation of the movable member 11 and the shielding member 13 will be described. FIG. 11 is a schematic cross-sectional view illustrating a part of the internal structure of the terminal attachment / detachment device 1 described in the present application. FIG. 11 shows a part of the movable member 11, the connecting member 12, and the shielding member 13 of the terminal attaching / detaching apparatus 1 in a state where the terminal 2 is not inserted as a cross-sectional view. FIG. 12 is a schematic cross-sectional view illustrating the terminal attaching / detaching device 1 described in the present application. FIG. 12 shows a cross-sectional view of an example of the terminal attaching / detaching device 1 in a state where the terminals 2 are inserted in the upper stage and the lower stage. The shielding member 13 has a substantially rectangular plate shape, and is formed in a tapered shape inclined from the upper end to the outer surface in the insertion direction of the terminal 2. The shielding member 13 is formed with a pressed portion 130 having a thickness that protrudes from a lower portion of the surface on the movable member 11 side. When the movable member 11 moves from the upper side (second position) to the lower side (first position), the pressed portion 130 comes into contact with the pressing portion 113 of the movable member 11 from above and is pressed downward. Is done. When the pressed portion 130 of the shielding member 13 is pushed downward, the shielding member 13 moves from the third position to the lower fourth position side against the shielding biasing member 15. That is, when the movable member 11 moves from the second position to the first position, the shielding member 13 moves from the third position to the fourth position in conjunction with the movable member 11.

In the state where the terminal 2 shown in FIG. 11 is not inserted, when the movable member 11 is pressed, the movable member 11 is moved downward and the shielding member 13 is also moved downward. When the pressing of the movable member 11 is released, the movable member 11 is pushed upward by the urging force of the movable member urging member 14. Further, since the movable member 11 moves upward, the shielding member 13 is released from the pressing of the movable member 11, so that the upward force is pushed upward by the urging force of the shielding urging member 15, and the upper end of the connecting member 12. It moves to the third position where it comes into contact with the restraining part 122 and is restrained from rising.

By depressing the movable member 11, the shielding member 13 moves downward, so that the lower second terminal receiving portion 120b is opened. At this time, since the locking portion 111 of the movable member 11 is also moved downward, the terminal 2 can be inserted into the second terminal receiving portion 120b. FIG. 12 shows a state in which the movable member 11 has moved to the first position, which is the lower end, and the terminal 2 has been inserted into both the upper first terminal receiving portion 120a and the lower second terminal receiving portion 120b. When the movable member 11 is located at the first position, the second terminal receiving portion 120b is in a state in which the terminal 2 can be inserted and removed. When the pressing of the movable member 11 is released from the state shown in FIG. 12, the movable member 11 is pushed upward by the urging force of the urging member 14 for the movable member, and therefore, the terminal 2 inserted into the second terminal receiving portion 120b. The locking part 111 of the movable member 11 is inserted from below into the locking hole 21 of the terminal 2 inserted into the locking hole 21 and the first terminal receiving part 120a. That is, both the terminal 2 inserted into the first terminal receiving portion 120a and the terminal 2 inserted into the second terminal receiving portion 120b are in a state where the locking portion 111 of the movable member 11 is locked. At this time, the pressing of the movable member 11 is released and the shielding member 13 rises. However, since the terminal 2 is inserted into the second terminal receiving portion 120b, the raising of the shielding member 13 causes the second terminal receiving portion 120b to rise. The terminal 2 inserted in the is restrained below the third position. In other words, when the movable member 11 is pressed, the shielding member 13 moves downward in conjunction with the movable member 11, but when the pressing of the movable member 11 is released, the shielding member 13 is not necessarily interlocked.

FIG. 13 is a schematic front view showing an example of the appearance of the terminal attaching / detaching device 1 described in the present application. FIG. 13 shows the front surface of the housing 10 of the terminal attaching / detaching device 1. Since the right movable member 11 is pressed and the shielding member 13 is also lowered, the shielding of the lower second terminal receiving portion 120b is released. In this state, the terminal 2 can be inserted into either the upper first terminal receiving portion 120a or the lower second terminal receiving portion 120b. Since the left movable member 11 is not pressed down and the shielding member 13 is also raised, the second terminal receiving portion 120b is shielded. In this state, the terminal 2 can be inserted into the first terminal receiving portion 120a, but the terminal 2 cannot be inserted into the second terminal receiving portion 120b. When the terminal 2 is inserted into the second terminal receiving portion 120b, it is necessary to push down the corresponding movable member 11 and push down the shielding member 13.
