Description

[Technical Field]

[0001] The present invention relates to a terminal holder capable of holding a terminal having a ring holder on the back surface. [Background technology]

[0002] Japanese Patent Publication No. 2024-934 (Patent Document 1) describes a terminal holding device that can fix a smartphone or tablet terminal, which has a ring holder on the back that can be inserted with a finger, to a desired location such as the interior of a car, the handlebars of a motorcycle, or the frame of a motorcycle.

[0003] The terminal holding device comprises a lower clamping plate having a first hook through-hole, an upper clamping plate having a second hook through-hole and arranged on the lower clamping plate so as to be openable and closable via a hinge, and a hook arranged on the lower clamping plate so as to be rotatable around a rotation axis arranged horizontally relative to the lower clamping plate and to be able to pass through the first and second through-holes.

[0004] In this terminal holding device, when the upper clamping plate is opened relative to the lower clamping plate, a ring holder is inserted into the hook passing through the first hook through-hole, and in this state, the upper clamping plate is closed and the hook passing through the second hook through-hole is rotated to engage with the upper clamping plate, thereby firmly holding a smartphone or tablet terminal having a ring holder on the back in the terminal holding device. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2024-934 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the terminal holding device described in the above publication requires at least four actions to hold a terminal: (1) opening the upper clamping plate relative to the lower clamping plate, (2) inserting the ring holder into the hook, (3) closing the upper clamping plate relative to the lower clamping plate, and (4) rotating the hook. Furthermore, when releasing the terminal from its holding position, at least three actions are required: (1) rotating the hook, (2) opening the upper clamping plate relative to the lower clamping plate, and (3) removing the ring holder from the hook. Therefore, there is still room for improvement in terms of the ease of holding a terminal in the terminal holding device and releasing the terminal from its holding position.

[0007] The present invention has been made in view of the above, and one of its objects is to provide a terminal holding device that can firmly hold a terminal while easily holding and releasing the terminal. [Means for solving the problem]

[0008] In order to achieve the above object, the terminal holding device of the present invention employs the following means.

[0009] According to a preferred embodiment of the terminal holding device of the present invention, there is provided a terminal holding device capable of holding a terminal having a ring holder on its rear surface. The terminal holding device includes a housing, a moving body, an engaging body, a state maintaining unit, and a first biasing unit. The housing includes an opening through which the ring holder can be inserted. The housing has an insertion passage extending in the insertion direction of the ring holder. The moving body has an abutment portion disposed in the insertion passage so that the ring holder can abut against it. The moving body is disposed on the housing so as to be movable in association with movement of the ring holder in the insertion direction. The engaging body is disposed on the housing so as to appear in the insertion passage as the moving body moves and to be able to engage with the inner hole of the ring holder. The state maintaining unit is capable of maintaining at least the state of the engaging body in at least an initial state and an engaged state, and is capable of releasing the state maintenance of the engaging body in the engaged state. The initial state is a state in which the engaging body is not present in the insertion passage, and the engaged state is a state in which the engaging body is present in the insertion passage. The first biasing portion is disposed between the movable body and the engaging body and the housing so as to bias the movable body and the engaging body with a force in a direction returning the movable body and the engaging body to their initial states. Here, the "terminal" in this invention typically refers to devices such as smartphones, mobile phones, and tablet terminals, which have a ring holder on the back. Furthermore, "movable" in this invention preferably includes not only a mode in which the movable body is movable in a linear direction, but also a mode in which the movable body is rotatable in a rotational direction.

[0010] According to the present invention, simply inserting the ring holder into the insertion passage through the opening in the housing causes the ring holder to engage with the engaging body, making it extremely easy to secure a terminal having a ring holder on its back surface to the terminal holding device. Moreover, in the engaged state, the engaging body appears in the insertion passage, preventing movement of the ring holder in the direction opposite to the insertion direction and maintaining the state of the engaging body, thereby reliably preventing the ring holder from falling out of the opening. Furthermore, since the state maintaining unit can release the state of the engaging body in the engaged state, the terminal holding device can be released from its hold.

[0011] According to a further aspect of the terminal holding device of the present invention, the movable body has a first rotation axis extending in the left-right direction toward the insertion direction. The movable body is supported by the housing so as to be rotatable about the first rotation axis. The abutment portion is disposed at a position spaced a first predetermined distance from the first rotation axis. The engagement body is integrated with the movable body so as to be disposed at a position spaced a second predetermined distance from the first rotation axis. The engagement body is brought into an engaged state by the movable body rotating in a first rotation direction toward the insertion direction from an initial state. The first biasing portion is capable of biasing the movable body in a second rotation direction that is opposite to the first rotation direction.

[0012] According to this aspect, the initial state and the engaged state can be realized with a simple configuration in which the moving body with which the engaging body is integrated is simply rotated in the first rotation direction and the second rotation direction.

[0013] According to a further aspect of the terminal holding device of the present invention, the state maintaining unit has a stopper and a ratchet mechanism. The stopper is disposed on the housing so as to abut against the moving body in the initial state and restrict rotation of the moving body in the second rotation direction. The ratchet mechanism allows rotation of the moving body in the first rotation direction but restricts rotation of the moving body in the second rotation direction.

[0014] According to this aspect, it is possible to achieve, with a simple configuration, maintaining the state of the moving body (engaging body) in the initial state and the engaged state, and releasing the state maintenance of the moving body that has been maintained in the engaged state.

[0015] According to a further aspect of the terminal holding device of the present invention, the ratchet mechanism includes a lever member having a tooth portion disposed on the movable body, a pawl portion engageable with the tooth portion and a second rotation axis parallel to the first rotation axis, and a second biasing portion disposed between the lever member and the housing. The lever member is supported by the housing so as to be rotatable about the second rotation axis. The second biasing portion biases the lever member in the first rotation direction.

[0016] According to this aspect, the ratchet mechanism can be ensured with a simple configuration.

[0017] According to a further aspect of the terminal holding device of the present invention, the lever member has an arm portion protruding from the housing, and the lever member can rotate in the second rotation direction against the biasing force of the second biasing portion by using the arm portion.

[0018] According to this aspect, by using the arm portion, it is possible to rotate the lever member in the second rotation direction against the biasing force of the second biasing portion. In other words, by simply rotating the lever member in the second rotation direction using the arm portion, it is possible to release the state of the movable body that has been maintained in the engaged state.

[0019] According to a further aspect of the terminal holding device of the present invention, the device further includes a pressing portion that is arranged to be able to appear and disappear on the surface of the housing where the opening is located, so that the back of the terminal when the ring holder is engaged with the engaging body can be pressed in the direction opposite to the insertion direction.

[0020] According to this aspect, it is possible to prevent rattling between the ring holder and the engaging body in the insertion direction due to a gap that occurs between the ring holder and the engaging body, thereby making it possible to hold the terminal more stably.

[0021] According to a further aspect of the terminal holding device of the present invention, the pressing portion has a plunger at least a portion of which is housed in the housing so as to be movable in the insertion direction, and a third biasing portion arranged between the plunger and the housing so as to bias the plunger in the direction opposite to the insertion direction.

[0022] According to this aspect, the pressing portion can be realized with a simple configuration.

[0023] According to a further aspect of the terminal holding device of the present invention, the pressing portion has a plurality of plungers and third biasing portions.

[0024] According to this aspect, the pressing force for pressing the terminal can be changed for each plunger, which makes it possible to apply the necessary pressing force to the necessary position, compared to when the terminal is pressed by a single plunger. [Effects of the Invention]

[0025] According to the present invention, it is possible to firmly hold a terminal, while easily realizing holding and releasing the terminal. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0027] Next, the best mode for carrying out the present invention will be described using examples. [Example]

[0028] 1 to 3, a terminal holding device 1 according to an embodiment of the present invention is configured as a device that can hold a terminal 2 such as a smartphone or tablet terminal having a ring holder RH on its back surface 2a (see FIG. 2) and fix it in a desired location DL (see FIG. 3). As shown in FIG. 4, the terminal holding device 1 includes a housing 10, a ratchet mechanism 12 disposed in the housing 10, and a pressing portion 14.

[0029] 1 and 2, the housing 10 has a substantially cubic shape, and is composed of a first housing 10a and a second housing 10b as shown in Fig. 4. In other words, the housing 10 is formed into a substantially cubic shape by joining the first housing 10a and the second housing 10b together.

[0030] As shown in FIGS. 5 and 6, the first housing 10a has recesses 21, 22, and 23 that open to a surface 20b (hereinafter referred to as the "front surface") perpendicular to the joining surface 20a, including the joining portion 20a' with the second housing 10b. The recess 21 also opens to the joining surface 20a and is disposed between the recesses 22 and 23. In other words, the recesses 22 and 23 are disposed so as to sandwich the recess 21. As shown in FIGS. 5 to 7, the recess 21 extends from the front surface 20b to a position near the surface 20c (hereinafter referred to as the "rear surface") that is paired with the front surface 20b, perpendicular to both the front surface 20b and the rear surface 20c. The recess 21 has a height dimension (the vertical direction in FIGS. 5 to 7) that is slightly larger than the thickness dimension of the ring holder RH so that the ring holder RH can be inserted therethrough. The recesses 22 and 23 extend from the front side surface 20b in the same direction as the recess 21. When viewed from one side in the extension direction, the recesses 22 and 23 have a substantially square shape. The length (depth) of the recesses 22 and 23 in the extension direction is smaller than the length (depth) of the recess 21 in the extension direction. As shown in FIG. 7, protrusions 22b and 23b are vertically provided on the bottom surfaces 22a and 23a of the recesses 22 and 23 toward the openings of the recesses 22 and 23 (toward the front side surface 20b).

[0031] As shown in FIGS. 5 and 6, the first housing 10a has support shafts 24a and 24b, a stopper 24c, and four guide openings 29a, 29b, 29c, and 29d. The support shafts 24a and 24b, the stopper 24c, and the guide openings 29a, 29b, 29c, and 29d are each disposed on the joint side surface 20a. The support shafts 24a and 24b and the stopper 24c have axes perpendicular to an imaginary plane including the joint 20a'. As shown in FIG. 6, the support shaft 24a is disposed on the recess 23 side (the lower side in FIGS. 5 to 7) with respect to the recess 21, approximately in the center between the front side surface 20b and the rear side surface 20c. The support shaft 24a has a joint shaft 24a' at its tip. The joint shaft 24a' has an outer diameter smaller than that of the support shaft 24a. As shown in Fig. 6, the joint shaft 24a' protrudes from an imaginary plane including the joint portion 20a'. The support shaft 24b is disposed on the recess 22 side (upper side in Figs. 5 to 7) with respect to the recess 21, and closer to the front side surface 20b (closer to the opening of the recess 22). The stopper 24c is disposed on the recess 23 side (lower side in Figs. 5 to 7) with respect to the recess 21, and closer to the front side surface 20b (closer to the opening of the recess 23). In other words, the stopper 24c can be said to be disposed directly below the support shaft 24b with the recess 21 in between. The guide openings 29a and 29b penetrate from the joint side surface 20a to the recess 22, and the guide openings 29c and 29d penetrate from the joint side surface 20a to the recess 23. 6, guide openings 29a and 29b extend from bottom surface 22a of recess 22 toward the opening of recess 22, and guide openings 29c and 29d extend from bottom surface 23a of recess 23 toward the opening of recess 23. Guide opening 29a is located near one surface 20d (hereinafter referred to as the "upper surface") of a pair of surfaces integrated with joining side surface 20a and front side surface 20b so as to be perpendicular to both of them, guide openings 29b and 29c are located near recess 21, and guide opening 29d is located near a surface 20e (hereinafter referred to as the "lower surface") that forms a pair with upper surface 20d.

[0032] Furthermore, as shown in FIGS. 5 and 6, the first housing 10a has a notched opening 25 and a notched recess 26 on the upper side surface 20d. The notched opening 25 opens to the joining side surface 20a and penetrates the upper side surface 20d. The notched opening 25 is located slightly closer to the rear side surface 20c than the center between the front side surface 20b and the rear side surface 20c. The notched opening 25 extends in the same direction as the recess 21 (either from the front side surface 20b toward the rear side surface 20c or in the opposite direction), and the dimension in the extension direction is set to the same value as the notched recess 26 (which is larger than the width dimension of the arm portion 42 of the lever 40 (the dimension in a direction perpendicular to both the longitudinal direction of the main body portion 41 and the extension direction of the arm portion 42, which will be described later). The notched recess 26 opens to both the lower side surface 20e and the connecting side surface 20a. The notched recess 26 is located closer to the rear side surface 20c.

[0033] The second housing 10b basically has a mirror image structure with respect to the first housing 10a, except that the support shaft 34a has a circular hole 34a' instead of the joining shaft 24a', and has a notch 37 with which the torsion coil spring 48 described later can be engaged.

[0034] Specifically, as shown in FIGS. 8 and 9, second housing 10b has recesses 31, 32, and 33 opening on a surface 30b (hereinafter referred to as the "front surface") perpendicular to joining surface 30a, including joining portion 30a' with first housing 10a. Recess 31 also opens on joining surface 30a and is disposed between recesses 32 and 33. In other words, recesses 32 and 33 are disposed on either side of recess 31. As shown in FIGS. 8 to 10, recess 31 extends from front surface 30b to a position near a surface 30c (hereinafter referred to as the "rear surface") 30c that is paired with front surface 30b, perpendicular to both front surface 30b and rear surface 30c. Recess 31 has a height dimension (vertical direction in FIGS. 8 to 10) slightly larger than the thickness dimension of ring holder RH so that ring holder RH can be inserted therethrough. The recesses 32 and 33 extend from the front side surface 30b in the same direction as the recess 31. When viewed from one side in the extension direction, the recesses 32 and 33 have a substantially square shape. The length (depth) of the recesses 32 and 33 in the extension direction is smaller than the length (depth) of the recess 31 in the extension direction. As shown in FIG. 10 , protrusions 32b and 33b are vertically provided on the bottom surfaces 32a and 33a of the recesses 32 and 33 toward the openings of the recesses 32 and 33 (toward the front side surface 30b).

[0035] As shown in FIGS. 8 and 9, the second housing 10b has support shafts 34a and 34b, a stopper 34c, a notch 37, and four guide openings 39a, 39b, 39c, and 39d. The support shafts 34a and 34b, the stopper 34c, the notch 37, and the guide openings 39a, 39b, 39c, and 39d are disposed on the joint side surface 30a. The support shafts 34a and 34b and the stopper 34c have axes perpendicular to an imaginary plane including the joint 30a'. As shown in FIG. 9, the support shaft 34a is disposed on the recess 33 side (the lower side in FIGS. 8 to 10) with respect to the recess 31, approximately in the center between the front side surface 30b and the rear side surface 30c. The support shaft 34a has a concentric circular hole 34a'. The circular hole 34a' has an inner diameter that is the same as or slightly smaller than the outer diameter of the joining shaft 24a'. The support shaft 34b is located on the recess 32 side (upper side in FIGS. 8 to 10) with respect to the recess 31, and is positioned closer to the front side surface 30b (closer to the opening of the recess 32). The stopper 34c is located on the recess 33 side (lower side in FIGS. 8 to 10) with respect to the recess 31, and is positioned closer to the front side surface 30b (closer to the opening of the recess 33). In other words, the stopper 34c can be said to be located directly below the support shaft 34b, with the recess 31 in between. As shown in FIGS. 8 and 9, the notch 37 opens to the joining side surface 20a and also opens in a direction facing the front side surface 30b. The notch 37 extends in the same direction as the recess 31 and parallel to the recess 31. The notch 37 is disposed on the recess 33 side (the lower side in FIGS. 8 and 9 ) of the recess 31, and closer to the rear side surface 30c than the support shaft 34a. The width dimension of the notch 37 (the vertical dimension in FIGS. 9 and 11 ) is set to be approximately the same as or slightly larger than the wire diameter of a torsion coil spring 48, which will be described later. The guide openings 39a and 39b penetrate from the joining side surface 30a to the recess 32, and the guide openings 39c and 39d penetrate from the joining side surface 30a to the recess 33. As shown in FIG. 9 , the guide openings 39a and 39b extend from the bottom surface 32a of the recess 32 toward the opening of the recess 32, and the guide openings 39c and 39d extend from the bottom surface 33a of the recess 33 toward the opening of the recess 33.The guide opening 39a is disposed at a position closer to one surface 30d (hereinafter referred to as the "upper surface") of a pair of surfaces that are integrated with the joining side surface 30a and the front side surface 30b so as to be perpendicular to both the joining side surface 30a and the front side surface 30b, the guide openings 39b and 39c are disposed at positions closer to the recess 31, and the guide opening 39d is disposed at a position closer to the surface 30e (hereinafter referred to as the "lower surface") that forms a pair with the upper surface 30d.

[0036] Furthermore, as shown in FIGS. 8 and 9, the second housing 10b has a notched opening 35 and a notched recess 36 on the upper side surface 30d. The notched opening 35 opens to the joining side surface 30a and penetrates the upper side surface 30d. The notched opening 35 is located slightly closer to the rear side surface 30c than the center between the front side surface 30b and the rear side surface 30c. The notched opening 35 extends in the same direction as the recess 31 (either from the front side surface 30b toward the rear side surface 30c or in the opposite direction), and its dimension in the extension direction is set to the same value as the notched recess 36 (which is set to a value larger than the width dimension of the arm portion 42 of the lever 40 (the dimension in a direction perpendicular to both the longitudinal direction of the main body portion 41 and the extension direction of the arm portion 42, which will be described later)). The notched recess 36 opens to both the lower side surface 30e and the joining side surface 30a. The notched recess 36 is located closer to the rear side surface 30c.

[0037] The first housing 10a and the second housing 10b thus configured are joined together with their joining sides 20a and 30a facing each other, as shown in FIG. 4, to form the housing 10. Here, because the first housing 10a and the second housing 10b are mirror images of each other, when the first housing 10a and the second housing 10b are joined together, the recess 21 and the recess 31, the support shaft 24a and the support shaft 34a, the support shaft 24b and the support shaft 34b, the stopper 24c and the stopper 34c, the notched opening 25 and the notched opening 35, the notched recess 26 and the notched recess 36, and the guide openings 29a, 29b, 29c, and 29d and the guide openings 39a, 39b, 39c, and 39d are aligned, respectively. Note that the alignment of the recesses 21 and 31 forms a single large recess, which forms the insertion passage IP (see FIG. 20) for the ring holder RH. Furthermore, since the joining shaft 24a' is fitted into the circular hole 34a', the joining between the first housing 10a and the second housing 10b becomes stronger.

[0038] As shown in FIG. 4, the ratchet mechanism 12 includes a lever 40, a rotor 44, a coil spring 46, and a torsion coil spring 48. As shown in FIG. 11, the lever 40 includes a main body 41 and an arm 42 integrated with the main body 41, and has a generally inverted T-shape when viewed from one side in the axial direction of the through-hole 41a. The ratchet mechanism 12 is an example of an embodiment corresponding to the "state maintaining unit" and "ratchet mechanism" of the present invention. The lever 40 is an example of an embodiment corresponding to the "lever member" of the present invention. The axis of the through-hole 41a is an example of an embodiment corresponding to the "second rotation axis" of the present invention.

[0039] As shown in FIG. 11 , the main body 41 has a through hole 41a at one longitudinal end and a locking projection 41b at the other longitudinal end. The main body 41 also has a plurality of pawl claws 41c between the through hole 41a and the locking projection 41b. The through hole 41a has an inner diameter slightly smaller than the outer diameter of the support shafts 24b and 34b. The locking projection 41b is disposed in a recess 41d provided at the other longitudinal end of the main body 41. The recess 41d opens toward the extension direction of the arm portion 42. The locking projection 41b extends in the same direction as the extension direction of the arm portion 42 and has an outer diameter equal to or slightly smaller than the inner diameter of the coil spring 46. The pawl claws 41c are disposed on a surface of the main body 41 that forms a pair with the surface to which the arm portion 42 is integrated. The pawl 41c has a downward slope from the through hole 41a toward the locking projection 41b (to the left in FIG. 11). The arm 42 is disposed at approximately the center in the longitudinal direction of the main body 41. The pawl 41c is an example of a feature that corresponds to the "pawl" of this invention.

[0040] As shown in Figures 12 to 14, the rotating body 44 has a boss portion 50 and a sectorial plate portion 52 integrated with the boss portion 50. As shown in Figures 12 and 14, the rotating body 44 also has a linear groove 44a extending from the boss portion 50 toward the outer circumferential surface of the sectorial plate portion 52. The linear groove 44a has a depth equal to or greater than half the wire diameter of the torsion coil spring 48. The rotating body 44 is an example of a configuration that corresponds to the "moving body" of this invention.

[0041] As shown in FIGS. 12 to 14, the boss portion 50 has a through hole 50a. The through hole 50a has an inner diameter slightly larger than the outer diameter of the support shafts 24a and 34a. As shown in FIG. 14, the sector-shaped plate portion 52 has a generally quarter-circular shape centered on the boss portion 50. In other words, the sector-shaped plate portion 52 has a generally sector shape with a central angle of 90 degrees. The sector-shaped plate portion 52 has a notch 52a opening at its outer periphery. The notch 52a has a generally C-shape when viewed from one side in the axial direction of the through hole 50a. The notch 52a is located approximately in the center in the circumferential direction. In other words, the sector-shaped plate portion 52 has a first portion 53a and a second portion 53b on either side of the notch 52a. The sector-shaped plate portion 52 also has a plurality of ratchet teeth 54 on its outer periphery. The ratchet teeth 54 have an upward slope from the first portion 53a to the second portion 53b (clockwise in FIG. 14). The notch 52a is an example of an embodiment corresponding to the "contact portion" of the present invention, and the second portion 53b is an example of an embodiment corresponding to the "engagement body" of the present invention. The ratchet teeth 54 are an example of an embodiment corresponding to the "tooth portion" of the present invention. Furthermore, the axis of the through hole 50a is an example of an embodiment corresponding to the "first rotation axis" of the present invention.

[0042] The coil spring 46 is assembled to the lever 40 by having one axial end thereof locked to the locking projection 41b (see FIG. 11) of the lever 40. The other axial end of the coil spring 46 is housed in the notched recesses 26, 36 of the housing 10. The coil spring 46 is an example of an embodiment that corresponds to a "second biasing portion" of the present invention.

[0043] The coil portion of the torsion coil spring 48 has an outer diameter slightly smaller than the inner diameter of the through hole 50a, and an inner diameter slightly larger than the outer diameter of the joining shaft 24a'. The torsion coil spring 48 is assembled to the rotating body 44 by arranging the coil portion in the through hole 50a (see FIG. 12) and arranging one of the pair of arms in the linear groove 44a (see FIG. 12). The other of the pair of arms of the torsion coil spring 48 is engaged with the notch 37 of the second housing 10b. The torsion coil spring 48 is an example of an embodiment that corresponds to the "first biasing portion" of this invention.

[0044] As shown in Fig. 4, the pressing portion 14 has four plungers 60, 60, 60, 60, and four coil springs 62, 62, 62, 62. As shown in Figs. 15 to 17, the plunger 60 has an abutting portion 60a and a sliding portion 60b. The coil spring 62 is an example of a configuration that corresponds to the "third biasing portion" of the present invention.

[0045] The contact portion 60a has a substantially square shape in a front view (when viewed from the direction of arrow V in FIG. 15), and has outer dimensions (vertical and horizontal dimensions of the square) that are larger than the inner dimensions (vertical and horizontal dimensions of the square) of the recesses 22, 23, 32, and 33. Note that the contact portion 60a is preferably configured so that a cushioning member is disposed on the front surface (the surface opposite to the side to which the sliding portion 60b is connected, the surface that comes into contact with the back surface 2a of the terminal 2, the right surface in FIG. 17).

[0046] One end of the sliding portion 60b in the longitudinal direction (the left-right direction in FIGS. 16 and 17 ) is integrally connected to the contact portion 60a, and the cross-sectional shape when cut along a plane perpendicular to the longitudinal direction is substantially square. The sliding portion 60b has outer dimensions (vertical and horizontal) that are the same as or slightly smaller than the inner dimensions of the recesses 22, 23, 32, and 33 (vertical and horizontal dimensions of the recesses 22, 23, 32, and 33). The sliding portion 60b also has a recess 61 that is open on the side opposite to the side connected to the contact portion 60a. In other words, the sliding portion 60b can be said to have a hollow cylindrical shape. A protrusion 61b is vertically disposed on the bottom surface 61a of the recess 61. That is, the protrusion 61b extends toward the opening of the recess 61. The protrusion 61b has an outer diameter slightly smaller than the inner diameter of the coil spring 62.

[0047] As shown in FIGS. 15 and 16, the sliding portion 60b has a pair of slits 64a, 64b and a pair of stoppers 66a, 66b. The slits 64a, 64b extend from the opening of the recess 61 toward the abutting portion 60a in the same direction as the recess 61. As shown in FIGS. 15 and 18, the slits 64a, 64b are disposed near the wall surface 65c on one of the two pairs of wall surfaces 65a, 65b and 65c, 65d that constitute the recess 61. This allows the wall surface 65c to bend toward the wall surface 65d. The stoppers 66a, 66b are disposed at the tip of the wall surface 65c (the end opposite the end connected to the abutting portion 60a) and protrude toward the side opposite the wall surface 65d. The stopper 66a is disposed closer to the wall surface 65a, and the stopper 66b is disposed closer to the wall surface 65b. The dimensions of the stoppers 66a and 66b in the direction along the extension direction of the recess 61 (the left-right direction in FIG. 16) are smaller than the lengths of the guide openings 29a, 29b, 29c, and 29d and the guide openings 39a, 39b, 39c, and 39d in the extension direction (the left-right direction in FIGS. 6 and 9). The dimensions of the stoppers 66a and 66b in the direction along the arrangement direction of the stoppers 66a and 66b (the up-down direction in FIG. 15) are slightly smaller than the width dimensions of the guide openings 29a, 29b, 29c, and 29d and the guide openings 39a, 39b, 39c, and 39d (the dimensions in the up-down direction in FIGS. 6 and 9). The stoppers 66a and 66b can bend toward the wall surface 65d together with the wall surface 65c.

[0048] Next, we will explain an example of how to assemble the thus configured terminal holding device 1. As shown in Fig. 4, the terminal holding device 1 can be assembled by, for example, assembling the ratchet mechanism 12 to the second housing 10b, joining the ratchet mechanism 12 to the first housing 10a, and then assembling the pressing part 14 to the housings 10 (first housing 10a and second housing 10b).

[0049] The ratchet mechanism 12 can be assembled to the second housing 10b by supporting the lever 40 with the coil spring 46 assembled thereto (one axial end of the coil spring 46 is engaged with the engaging projection 41b) on the support shaft 34b via the through-hole 41a so that the arm portion 42 is positioned within the notched opening 35 of the second housing 10b, and supporting the rotor 44 with the torsion coil spring 48 assembled thereto on the support shaft 34a via the through-hole 50a so that the ratchet teeth 54 engage with the pawl 41c. At this time, the other axial end of the coil spring 46 is housed in the notched recess 36 of the second housing 10b, and the arm portion of the torsion coil spring 48 that is not engaged with the linear groove 44a is engaged with the notch 37.

[0050] Furthermore, the pressing portion 14 can be attached to the housings 10 (first housing 10a and second housing 10b) by first inserting the coil spring 62 into the recesses 22 and 23 of the first housing 10a and the recesses 32 and 33 of the second housing 10b, and then inserting the plunger 60 into the recesses 22 and 23 into which the coil spring 62 has been inserted and into the recesses 32 and 33 of the second housing 10b (see FIG. 4). Here, the plunger 60 is inserted into the recesses 22 and 23 and the recesses 32 and 33 of the second housing 10b by accommodating the coil spring 62 in the recess 61, pinching the wall surfaces 65c and 65d to bend the wall surface 65c toward the wall surface 65d, and then inserting the plunger 60 into the recess 61 against the spring force of the coil spring 62. When the insertion of plunger 60 into recesses 22 and 23 and recesses 32 and 33 of second housing 10b is completed, stopper 66a engages with guide openings 29a, 29c, 39a, and 39c, and stopper 66b engages with guide openings 29b, 29d, 39b, and 39d. Also, as shown in Fig. 19, one axial end of coil spring 62 engages with protrusions 22b, 23b, 32b, and 33b, and the other axial end of coil spring 62 engages with protrusion 61b.

[0051] The terminal holding device 1 assembled in this manner is set to an initial state in which the opening of the notch 52a of the rotating body 44 and the opening of the insertion passage IP of the housing 10 are aligned, as shown in Fig. 20. This initial state is maintained by the cooperative action of the housing 10 and the ratchet mechanism 12. Specifically, the initial state is maintained by the spring forces of the coil spring 46 and the torsion coil spring 48, and the stoppers 24c and 34c.

[0052] Next, we will explain the operation of the terminal holding device 1 configured in this way, in particular the operation when the terminal 2 is held in the terminal holding device 1, and the operation when the terminal holding device 1 releases the holding of the terminal 2. First, we will explain the operation when the terminal 2 is held in the terminal holding device 1, and then we will explain the operation when the terminal holding device 1 releases the holding of the terminal 2.

[0053] When holding the terminal 2 in the terminal holding device 1, as shown in Fig. 20, the ring holder RH attached to the back surface 2a of the terminal 2 is inserted into the insertion passage IP, and the back surface 2a of the terminal 2 is brought into contact with the contact portion 60a of the plunger 60. At this time, the ring holder RH inserted into the insertion passage IP is placed in the notch 52a of the rotating body 44. In this state, the terminal 2 is pressed in a direction approaching the housing 10 against the pressing force of the pressing portion 14 (the spring force of the coil spring 62) so that the ring holder RH moves to the back side of the insertion passage IP. Here, each plunger 60 slides in the extension direction of the insertion passage IP (extension direction of recesses 22, 23, 32, 33) with stoppers 66a, 66b guided by guide openings 29a, 29b, 29c, 29d and guide openings 39a, 39b, 39c, 39d, so that the protruding and retracting movement (linear reciprocating movement) of each plunger 60 can be made smooth.

[0054] As the ring holder RH moves toward the back of the insertion passage IP, the ring holder RH presses the first portion 53a of the rotating body 44 in the movement direction via the notch 52a. As a result, as shown in FIGS. 21 and 22, the rotating body 44 rotates (counterclockwise in FIGS. 21 and 22) in the movement direction of the ring holder RH (leftward in FIGS. 21 and 22), and the second portion 53b of the rotating body 44 appears in the insertion passage IP (see FIGS. 21 and 22). As a result, the second portion 53b is inserted into the inner hole of the ring holder RH, establishing an engaged state in which the second portion 53b and the ring holder RH engage with each other. In other words, the engaged state can be described as a state in which the ring holder RH is confined within the closed space formed by the insertion passage IP and the notch 52a. The direction in which the rotating body 44 rotates toward the moving direction of the ring holder RH (counterclockwise in FIGS. 21 and 22) is an example of an embodiment that corresponds to the "first rotation direction" of the present invention.

[0055] Here, when the rotating body 44 rotates in the movement direction of the ring holder RH (counterclockwise in FIGS. 21 and 22 ), the ratchet teeth 54 and the pawl 41 c engage with each other, so that the rotating body 44 can be maintained at a predetermined rotational position. That is, the engagement between the second portion 53 b and the ring holder RH can be maintained. This reliably prevents the ring holder RH from falling out of the insertion passage IP not only during the operation for holding the terminal 2 in the terminal holding device 1 but also after the operation is completed. Note that the ratchet teeth 54 and the pawl 41 c are inclined in a direction that allows the rotating body 44 to rotate in the movement direction of the ring holder RH (counterclockwise in FIGS. 21 and 22 ). Therefore, the rotating body 44 can smoothly rotate in the movement direction of the ring holder RH (counterclockwise in FIGS. 21 and 22 ) while effectively preventing the rotating body 44 from rotating in the direction opposite to the movement direction of the ring holder RH (clockwise in FIGS. 21 and 22 ).

[0056] Furthermore, when the second portion 53b and the ring holder RH are engaged, the pressing force from the pressing portion 14 (the spring force of the coil spring 62) acts on the ring holder RH in the direction opposite to the movement direction of the ring holder RH (leftward in FIGS. 21 and 22). This prevents rattling caused by a clearance between the ring holder RH and the second portion 53b in the extension direction of the insertion passage IP. As a result, the terminal 2 can be held more stably by the terminal holding device 1.

[0057] When releasing the terminal 2 from the terminal holding device 1, as shown in FIG. 23, the lever 40 is rotated (clockwise in FIG. 23) using the arm 42 against the spring force of the coil spring 46. This releases the engagement between the pawl 41c and the ratchet teeth 54, and the spring force (restoring force) of the torsion coil spring 48 rotates the rotor 44 in the direction opposite to the moving direction of the ring holder RH until the second portion 53b abuts against the stoppers 24c and 34c (clockwise in FIG. 23). As a result, the terminal holding device 1 returns to its initial state in which the opening of the notch 52a and the opening of the insertion passage IP are aligned, and the ring holder RH is released from the closed space formed by the insertion passage IP and the notch 52a. In this way, the terminal 2 is released from the terminal holding device 1. The direction in which the rotating body 44 rotates in the opposite direction to the moving direction of the ring holder RH (clockwise direction in FIG. 23) is an example of an embodiment that corresponds to the "second rotation direction" of the present invention.

[0058] As described above, according to the terminal holding device 1 of the embodiment of the present invention, with the ring holder RH inserted into the insertion passage IP of the housing 10, simply pressing the terminal 2 toward the housing 10 establishes engagement between the ring holder RH and the rotating body 44, making it extremely easy to hold the terminal 2 having the ring holder RH on the back surface 2a in the terminal holding device 1. Moreover, the ratchet mechanism 12 can maintain the engagement between the ring holder RH and the rotating body 44, making it possible to reliably prevent the ring holder RH from falling out of the insertion passage IP. Of course, simply operating the arm portion 42 can release the engagement maintained by the ratchet mechanism 12, making it easy to release the terminal 2 from being held by the terminal holding device 1.

[0059] Furthermore, according to the terminal holding device 1 of the embodiment of the present invention, when the ring holder RH and the rotating body 44 are engaged, the pressing force (spring force of the coil spring 62) from the pressing portion 14 acts on the ring holder RH, preventing rattling caused by the clearance between the ring holder RH and the rotating body 44 in the extension direction of the insertion passage IP, thereby making it possible to more stably hold the terminal 2 by the terminal holding device 1. Note that, because the pressing portion 14 has multiple plungers 60 and coil springs 62, the pressing force that presses the back surface 2a of the terminal 2 can be changed for each plunger 60. This makes it possible to apply the required pressing force to the required position compared to when the back surface 2a of the terminal 2 is pressed by a single plunger 60.

[0060] In the embodiment of the present invention, the rotating body 44 is maintained at a predetermined rotational position by the ratchet mechanism 12, but this is not limiting. For example, the rotating body 44 may be maintained at a predetermined rotational position using a magnet, or a fastening member such as a screw.

[0061] In the embodiment of the present invention, the rotating body 44 comes into contact with the ring holder RH moving inside the insertion passage IP toward the rear (in the direction away from the opening of the insertion passage IP) and rotates in response to the abutment of the ring holder RH, thereby engaging with the ring holder RH. However, the present invention is not limited to this. For example, as shown in a modified terminal holding device 100 illustrated in Fig. 24, the terminal holding device 100 may be configured to have a moving body 144 that comes into contact with the ring holder RH moving inside the insertion passage IP toward the rear (in the direction away from the opening of the insertion passage IP) and moves linearly in the same direction as the movement of the ring holder RH in response to the abutment of the ring holder RH, and an engaging body 145 that rotates in response to the linear movement of the moving body 144 and engages with the ring holder RH.

[0062] 24, the terminal holding device 100 of the modified example basically has the same configuration as the terminal holding device 1 according to the embodiment of the present invention described above, except that the housing 10 is replaced with a housing 110 and the ratchet mechanism 12 is replaced with a ratchet mechanism 112. Therefore, the same parts of the terminal holding device 100 of the modified example as those of the terminal holding device 1 according to the embodiment of the present invention described above are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0063] As shown in FIG. 24, the housing 110 has the same configuration as the housing 10, except that the support shafts 24a, 34a, stoppers 24c, 34c, and notch 37 have been removed, and spring receiving recesses 136, 137 have been newly added, so that the housing 110 is configured to support the moving body 144 so that the moving body 144 can move in the same direction as the extension direction of the insertion passage IP, and is configured to support the engaging body 145 rotatably.

[0064] As shown in FIG. 24, the ratchet mechanism 112 has a lever 140, a moving body 144, an engaging body 145, and coil springs 46, 146, and 148. As shown in FIG. 24, the lever 140 has the same configuration as the lever 40 except that the pawl 41c is replaced with a pawl 141c. As shown in FIG. 24, the moving body 144 has a spring receiving recess 148a capable of accommodating the coil spring 148, a cam surface 149, and ratchet teeth 154. The moving body 144 is assembled to the housing 110 so that the cam surface 149 slopes downward from the bottom side of the insertion passage IP toward the opening side (to the right in FIG. 24). Note that, when the moving body 144 is assembled to the housing 110, the ratchet teeth 154 slope upward from the bottom side of the insertion passage IP toward the opening side (to the right in FIG. 24). The movable body 144 is biased toward the opening of the insertion passage IP by a coil spring 148 housed in the spring receiving recesses 136 and 148a. As shown in Fig. 24, the engaging body 145 has a contact 145a that can come into contact with the cam surface 149, an engaging protrusion 145b that can engage with the ring holder RH, and a base portion 145c that connects the contact 145a and the engaging protrusion 145b, and is generally U-shaped when viewed from the front (when viewed perpendicular to the paper surface of Fig. 24). The base portion 145c has a spring receiving recess 145d that can house the coil spring 146. The spring receiving recess 145d is located on the contact 145a side with respect to the rotation axis of the engaging body 145. As a result, when engaging body 145 is assembled to housing 110, coil spring 146 housed in spring receiving recesses 137 and 145d urges contactor 145a in a direction (clockwise in FIG. 24) in which contactor 145a abuts cam surface 149. Ratchet mechanism 112 corresponds to the "state maintaining portion" and "ratchet mechanism" of the present invention, lever 140 corresponds to the "lever member" of the present invention, pawl 141c corresponds to the "claw portion" of the present invention, coil springs 146 and 148 correspond to the "first urging portion" of the present invention, and ratchet teeth 154 are an example of an embodiment corresponding to the "tooth portion" of the present invention.

[0065] When holding the terminal 2 in the terminal holding device 1 configured in this manner, as shown in Fig. 24, the ring holder RH attached to the back surface 2a of the terminal 2 is inserted into the insertion passage IP, and with the back surface 2a of the terminal 2 abutting against the abutting portion 60a of the plunger 60, the terminal 2 is pressed in a direction toward the housing 10 against the pressing force of the pressing portion 14 (the spring force of the coil spring 62) so that the ring holder RH moves further to the back side of the insertion passage IP. As the ring holder RH moves to the back side of the insertion passage IP, the moving body 144 is pressed by the ring holder RH and moves in the same direction as the moving direction of the ring holder RH (leftward in Fig. 25), as shown in Fig. 25. As the moving body 144 moves, the contact 145a is pressed by the cam surface 149, and the engaging body 145 rotates against the spring force of the coil spring 146 (the counter-rotation direction shown in Figs. 24 and 25). This causes the engaging protrusion 145b to appear in the insertion passage IP. As a result, the engaging protrusion 145b is inserted into the inner hole of the ring holder RH, establishing an engaged state in which the engaging body 145 and the ring holder RH are engaged with each other.

[0066] Here, when the engaging body 145 and the ring holder RH are engaged (see FIG. 25), the ratchet teeth 154 and the pawl claw 141c mesh with each other, so that the engaged state between the engaging body 145 and the ring holder RH can be maintained. This makes it possible to reliably prevent the ring holder RH from falling out of the insertion passage IP not only during the operation for holding the terminal 2 in the terminal holding device 1, but also after the operation is completed.

[0067] When the engaging body 145 and the ring holder RH are engaged, the pressing force from the pressing portion 14 (spring force of the coil spring 62) acts on the ring holder RH in the direction opposite to the moving direction of the ring holder RH (leftward in FIG. 26), thereby preventing rattling caused by clearance between the ring holder RH and the engaging body 145 (engaging protrusion 145b) that occurs in the extending direction of the insertion passage IP. As a result, the terminal 2 can be held more stably by the terminal holding device 1.

[0068] When releasing the hold of the terminal 2 by the terminal holding device 1, as shown in Fig. 27, simply by using the arm portion 42 to rotate the lever 140 against the spring force of the coil spring 46 (clockwise in Fig. 27), the engagement between the pawl 141c and the ratchet teeth 154 is released, and the spring force (restoring force) of the coil spring 148 moves the moving body 144 in the direction opposite to the moving direction of the ring holder RH (to the right in Fig. 27). As a result, the spring force (restoring force) of the coil spring 146 rotates the engaging body 145 in a direction in which the engagement between the engaging protrusion 145b and the ring holder RH is released (clockwise in Fig. 27). As a result, the engagement between the engaging protrusion 145b and the ring holder RH is released, and the holding of the terminal 2 by the terminal holding device 1 is released.

[0069] The present embodiment shows an example of a mode for carrying out the present invention, and therefore the present invention is not limited to the configuration of the present embodiment. [Explanation of symbols]
