Here, the concave portion 24 for the movable body is opened to the outside in the front-rear direction, and the knob 41 b projects from the housing 2 to the outside in the front-rear direction and receives an operating force.

  Further, the sandwiching plate 42 is formed by punching and bending a metal plate, for example, and a main body portion 42a whose thickness direction is directed upward and downward, and each of which is cut upward from the main body portion 42a. And two sandwiched portions 42b. In the holding plate 42, two wire insertion holes 42c are formed in the main body portion 42a as the above-described holding portion 42b is cut and raised. Further, in the base 41, a holding groove 41c extending in the circumferential direction is provided on the inner peripheral surface of the main body 41a, and a part of the main body 42a of the holding plate 42 is stored in the holding groove 41c. Further, an interlocking recess (not shown) reaching the knob 41b is provided in the holding groove 41c. In the sandwiching plate 42, an interlocking convex portion (not shown) that engages with the engaging recess is provided on the main body 42a in a radial direction, and the interlocking convex portion is an inner surface of the interlocking recess. The base 41 and the clamping plate 42 rotate in conjunction with each other.

  The clamping plate 42 is provided with a spring insertion hole 42d into which one end of the contact pressure spring 5 is inserted. The movable body 4 receives the spring force of the contact pressure spring 5 on the inner surface of the spring insertion hole 42d. Furthermore, the other end of the contact pressure spring 5 is fixed to the body 2a by an appropriate means (for example, fitting), whereby the movable body 4 is urged counterclockwise with respect to the housing 2 as viewed from above.

  The operation of this embodiment will be described. In a state where the electric wire 6 is not inserted into any corresponding electric wire insertion hole 21 and the knob portion 41b is not subjected to an operating force, the deformation amount of the contact pressure spring 5 is minimized. At this time, each clamping portion 42b is Each one is located above one wire insertion hole 21.

  When inserting the electric wire 6 into the electric wire insertion hole 21, the knob 41 b is pushed leftward against the spring force of the contact pressure spring 5, and the movable body 4 is rotated clockwise as viewed from above with respect to the housing 2. Each clamping part 42b is retracted from the upper side of the electric wire insertion hole 21 and each electric wire insertion hole 42c of the movable body 4 is positioned above the electric wire insertion hole 21, respectively. In this state, the electric wire 6 is inserted until the tip (upper end) of the electric wire 6 reaches the upper side of the lower end of the contact portion 32, and then the operation force to the knob 41b is released. Then, the movable body 4 rotates counterclockwise as viewed from above with respect to the housing 2 by the spring force of the contact pressure spring 5, and the electric wire 6 is pressed against the contact portion 32 by the clamping portion 42b. Further, the tip of the sandwiching part 42b bites into the electric wire 6 (that is, the electric wire 6 is locked by the sandwiching part 42b), so that the electric wire 6 is prevented from falling off. Here, a circular arc-shaped positioning recess 42e is provided at the tip of each clamping portion 42b, and part of the electric wire 6 is accommodated in the positioning recess 42e, so that the horizontal direction (that is, rotation) Misalignment in the direction of changing the distance from the shaft) is prevented.

  Here, for example, when the distance from the rotation axis differs between the contact portions 32 and between the sandwiching portions 42b, the contact portion 32 and the sandwiching portion 42b that are further away from the rotation shaft sandwich the contact portion 32 closer to the rotation shaft. The holding force with respect to the electric wire 6 will become lower than with the part 42b. On the other hand, in this embodiment, each contact part 32 and each clamping part 42b have a two-fold rotational symmetry with respect to the rotation axis, that is, they are arranged equidistant from the rotation axis. Therefore, when all the electric wires 6 have the same diameter, the holding force is equal to all the connected electric wires 6.

  On the contrary, when the electric wire 6 is pulled out from the electric wire insertion hole 21, the electric wire 6 is released while releasing the lock of the holding portion 42b by pushing the knob 41b to the left against the spring force of the contact pressure spring 5. By pulling downward, the electric wire 6 can be extracted from the electric wire insertion hole 21.

  The quick connection terminal device 1 may correspond to three electric wire insertion holes 21 as shown in FIG. In the example of FIG. 7, the three electric wire insertion holes 21 are provided in an equilateral triangle vertex arrangement. In this way, in the quick connection terminal device 1 corresponding to the three electric wire insertion holes 21, as shown in FIG. 8, the three contact portions 32 and the holding portions 42b are three-fold rotationally symmetrical. However, the other parts are the same as those of the quick-connection terminal device 1 described with reference to FIGS.

  According to the above configuration, since the electric wire 6 is locked by the holding portion 42b and the electric wire 6 is pressed against the contact portion 32, the locking portion 72 and the electric wire 6 that lock the electric wire 6 as in the conventional example of FIG. The dimension in the insertion direction of the electric wire 6 can be reduced as compared with the case where the pressing portion 73 for pressing the contact portion 32 on the contact portion 32 is provided separately in the insertion direction of the electric wire 6.

  In addition, a contact pressure spring 5 made of a torsion coil spring having an axial direction directed in the vertical direction as the insertion direction of the wire 6 is used, and the contact pressure spring 5 surrounds each connected wire 6. 17 is a dimension in the insertion direction of the electric wire 6 as compared with the case where the locking spring 7 having the locking portion 72 inclined in the insertion direction of the electric wire 6 is used as in the conventional example of FIG. Can be reduced.

  Further, in the sandwiching plate 42 of the movable body 4, the sandwiching portion 42 b protrudes above the main body portion 42 a (that is, the side in which the electric wire 6 is inserted), and in the terminal plate 3, the contact portion 32 is below the main body portion 31. It protrudes (that is, the direction from which the electric wire 6 is pulled out). Accordingly, the upper and lower positions of the contact position with respect to the holding portion 42b and the contact position with respect to the contact portion 32 in the electric wire 6 to be locked are compared with the case where the holding plate 42 and the terminal plate 3 of the movable body 4 are not bent and flattened. Since the shift in the direction (that is, the length direction of the electric wire 6) is small, the electric wire 6 is hardly bent. Therefore, the contact pressure of the electric wire 6 with respect to the terminal plate 3 can be increased relative to the spring force of the contact pressure spring 5.

  Moreover, the rotation amount of the movable body 4 changes according to the diameter of the electric wire 6, whereby a plurality of types of electric wires 6 having different diameters can be locked.

  In order to deepen the sandwiching portion 42b into the electric wire 6 and further strengthen the holding force with respect to the electric wire 6, the portion of the sandwiching portion 42b that bites into the electric wire 6 (in this embodiment, inside the positioning recess 42e). The cross section is preferably an acute angle shape.

(Embodiment 2)
Compared with the quick-connection terminal device 1 corresponding to the two electric wire insertion holes 21 in the first embodiment, the present embodiment is common except for the structure of the movable body 4, so illustration and description of common parts are omitted. To do.

  In the present embodiment, the main body 41a of the base 41 of the movable body 4 has an annular shape instead of an arc shape, as shown in FIG. The outer diameter of the main body portion 41a is slightly smaller than the inner diameter of the concave portion 24 for the movable body, and the outer peripheral surface of the main body portion 41a is in sliding contact with the inner peripheral surface of the concave portion 24 for the movable body. It can rotate around the central axis of the recess 24 for use.

  In the first embodiment, the clamping plate 42 is connected to one end of the contact pressure spring 5, whereas in the present embodiment, the base 41 is connected to one end of the contact pressure spring 5. As means for connecting one end of the contact pressure spring 5 to the base 41, for example, fitting can be used.

  Further, in the base 41 of the movable body 4, a sandwiching plate recess 41 d that is recessed in a cylindrical shape is provided on the upper surface of the main body 41 a, and an interlocking recess 41 e that communicates with the sandwiching plate recess 41 d on the upper surface of the knob 41 b. Is provided. The rotation of the clamping plate 42 with respect to the base 41 is restricted by the interlocking convex portion 42f protruding in the radial direction from the main body 42a in the clamping plate 42 abutting against the inner surface of the interlocking concave portion 41e. Thereby, the clamping plate 42 rotates in conjunction with the base 41 with respect to the housing 2. That is, in the present embodiment, the clamping plate 42 receives the spring force of the contact pressure spring 5 via the base 41.

  Further, as shown in FIG. 10, the movable body 4 has a cover 43 that is attached to the upper side of the base 41 and prevents the holding plate 42 from dropping off above the base 41. The cover 43 is made of synthetic resin, for example. As means for coupling the cover 43 to the base 41, for example, known means such as fitting or adhesion can be used. The cover 43 includes a ring-shaped main body 43a in which insertion holes 43c through which the clamping part 42b and the electric wires 6 are inserted are vertically provided, and is protruded in a radial direction from the main body 43a, and is arranged above the knob 41b. And a convex portion 43b for covering.

  In the movable body 4, the inner diameter of the sandwiching plate recess 41 d of the base 41 is larger than the outer diameter of the main body portion 42 a of the sandwiching plate 42, and the sandwiching plate 42 projects in the protruding direction of the interlocking projection 42 f with respect to the base 41. Can be translated in parallel. Further, the insertion hole 43c of the cover 43 has a dimension and shape that is sufficiently large so as not to interfere with the holding portion 42b even if the holding plate 42 is displaced with respect to the base 41. Further, in the clamping plate 42, the protruding direction of the interlocking convex portion 42f is a direction intersecting the direction in which the two clamping portions 42b are arranged. In other words, the sandwiching plate 42 can be translated in a direction intersecting the direction in which the two sandwiching portions 42b are arranged. In other words, the sandwiching plate 42 can be translated with respect to the base 41 in the direction in which each sandwiching portion 42 b contacts the electric wire 6. Therefore, when the clamping plate 42 moves in parallel with respect to the base 41 as described above, the distance from the clamping part 42b to the contact part 32 with respect to a certain amount of rotation of the movable body 4 is equal to one clamping part 42b. It increases and decreases in the other clamping part 42b.

  Here, in Embodiment 1, when there is a difference in diameter between the electric wires 6, the rotation of the movable body 4 stops when one electric wire 6 having a larger diameter is locked. In other words, the electric wire 6 having a smaller diameter could not be locked. On the other hand, in the present embodiment, when the diameters of the electric wire 6 locked to the one holding portion 42b and the electric wire 6 locked to the other holding portion 42b are different, only the difference in diameter. Since the clamping plate 42 moves in parallel with respect to the base 41, the electric wire 6 can be locked by both the clamping portions 42b.

In addition, on one surface of the base 41 in the axial direction, there is provided a clamping plate recess 41d in which the radial end of the clamping plate 42 and the interlocking projection 42f are accommodated. The base 41 and the sandwiching plate 42 are interlocked with each other when the interlocking convex portion 42f contacts the inner surface of the sandwiching plate concave portion 41d in the knob 41b. The bases 41 of the two movable bodies 4a and 4b are oriented so that the sandwiching plate recesses 41d face each other. In this state, each knob 41b protrudes outward in the vertical direction with respect to the main body 41a. To do. The direction in which the knob 41b protrudes is the direction away from the rotation axis of the movable bodies 4a and 4b.

  In the terminal board 3, the two contact portions 32 are arranged side by side on the same plane with the thickness direction in the front-rear direction. Further, due to the spring force of the contact pressure spring 5, the sandwiching portion 42 b that sandwiches the electric wire 6 with the left contact portion 32 is urged clockwise as viewed from above, and the electric wire is between the right contact portion 32. The clamping portion 42b that clamps 6 is biased counterclockwise as viewed from above. That is, each clamping part 42b clamps the electric wire 6 between the front surfaces of the contact parts 32, respectively.

  According to the said structure, since the movable bodies 4a and 4b one for every electric wire 6 lock, the two electric wires 6 from which a diameter mutually differs can be locked simultaneously.

  Further, in the present embodiment, in a state in which each clamping part 42b holds the electric wire 6 between each of the clamping parts 42b, the knob 41b of the upper movable body 4a is more than the knob 41b of the lower movable body 4b. Is also located on the counterclockwise side when viewed from above. That is, in the above state, each knob 41b is positioned such that each knob 41b is located on the side of displacement relative to the other knob 41b when the holding part 42b is moved closer to the contact part 32. Has been placed. That is, in a state where each clamping part 42b holds the electric wire 6 between each of the contact parts 32, a force is applied to each of the two knobs 41b in a direction to reduce the distance between the knobs 41b. The locks can be released for both electric wires 6. Further, if a force in the above direction is applied only to one knob 41b, the lock can be released only for one electric wire 6.

  Contrary to the above, in the state where each clamping portion 42b clamps the electric wire 6 between the respective clamping portions 42b, each knob 41b contacts the clamping portion 42b more than the other knob 41b. Each knob 41b may be arranged so as to be positioned on the direction side that is displaced when being separated from the portion 32. In this case, the locking can be released for both the electric wires 6 by applying a force to the two knobs 41b in the direction of increasing the distance between the knobs 41b. Further, if a force in the above direction is applied only to one knob 41b, the lock can be released only for one electric wire 6.

  In addition, parts having the same shape may be used by the two movable bodies 4a and 4b. For example, if the bases 41 having the same shape are used upside down, the manufacturing cost can be reduced as compared with the case where the two movable bodies 4a and 4b do not use parts having the same shape.

  Further, in each of the above embodiments, the direction in which the contact pressure spring 5 is elastically deformed when the movable bodies 4, 4 a, 4 b are rotated in the direction in which the clamping portion 42 b is separated from the contact portion 32 is the coil shape of the contact pressure spring 5. May coincide with the winding direction of the portion (that is, the direction in which the contact pressure spring 5 is closed), or may be in the opposite direction (that is, the direction in which the contact pressure spring 5 is opened). In any case, the inner diameter of the spring recess 23 needs to be larger than the outer diameter of the contact pressure spring 5 in a state where the outer diameter is larger than before and after the elastic deformation. In general, in a torsion coil spring such as the contact pressure spring 5, it is known that the spring force increases as the diameter of the coiled portion decreases.

  Further, in each of the above embodiments, instead of forming the contact portion 32 and the sandwiching portion 42b by cutting and raising, the inner surface of the through hole 31a provided in the terminal plate 3 is used as the contact portion, and the electric wire insertion hole provided in the sandwich plate 42 It is good also considering the inner surface of 42c and the end surface of the clamping board 42 as a clamping part.
