Summary of the Invention

Problems to be Solved by the Invention

[0004] In the terminal protection cover described in Patent Document 1 above, a locking portion is provided on the other side wall opposite to the hinge side, and the lid portion is locked to the other side wall of the main body portion in the closed position. By the way, it is conceivable to firmly lock the lid portion to the main body portion by providing a locking portion also on one side wall on the hinge side. In this case, it is desired to improve workability by smoothly locking the lid portion to the main body portion.

[0005] Therefore, the present invention has been made in view of the above, and an object thereof is to provide a terminal cover and a terminal with a cover that can improve workability.

Means for Solving the Problems

[0006] In order to solve the above-described problems and achieve the object, the terminal cover according to the present invention can accommodate the connection portion of the terminal with the electric wire in a closed state where each is rotated along the rotation direction around the rotation axis and combined with each other. The first cover member and the second cover member each have a center side wall portion provided on the center side of the rotation locus when rotating along the rotation direction, and a tip side wall portion provided on the tip side of the rotation locus. The first cover member and the second cover member each have a center side wall portion provided on the center side of the rotation locus when rotating along the rotation direction around the rotation axis, and a tip side wall portion provided on the tip side of the rotation locus. In a closed state where each is rotated along the rotation direction and combined with each other, the first cover member and the second cover member can accommodate the connection portion of the terminal with the electric wire. A hinge that connects the first cover member and the second cover member so as to be openable and closable in the rotation direction. A center side hook portion provided on one of the center side wall portions of the first cover member or the second cover member, and a center side claw portion provided on the other center side wall portion of the first cover member or the second cover member. In the closed state, the center side hook portion is hooked on the center side claw portion to lock the first cover member and the second cover member. A center side locking mechanism. A tip side hook portion provided on one of the tip side wall portions of the first cover member or the second cover member, and a tip side claw portion provided on the other tip side wall portion of the first cover member or the second cover member. In the closed state, the tip side hook portion is hooked on the tip side claw portion to lock the first cover member and the second cover member together with the center side locking mechanism. A tip side locking mechanism. A guide mechanism provided for the tip side locking mechanism to guide the tip side hook portion along the rotation direction toward the tip side claw portion when the first cover member and the second cover member are rotated and combined along the rotation direction. The tip side locking mechanism is such that when the first cover member and the second cover member are rotated and combined along the rotation direction, if the tip side hook portion is not displaced in the axial direction along the rotation axis with respect to the tip side claw portion, the guide mechanism guides the tip side hook portion along the rotation direction toward the tip side claw portion. If the tip side hook portion is displaced in the axial direction with respect to the tip side claw portion,When the tip-side hooking portion interferes with the guide mechanism, even when the center-side hooking portion is displaced in the axial direction with respect to the center-side claw portion when the center-side locking mechanism rotates and combines the first cover member and the second cover member along the rotation direction, a movement space portion in which the center-side hooking portion is movable in the rotation direction is formed around the center-side claw portion.

[0007] The terminal with a cover according to the present invention includes a terminal having conductivity and connected to an electric wire, and a terminal cover capable of accommodating a connection portion between the terminal and the electric wire. The terminal cover can accommodate the connection portion between the terminal and the electric wire in a closed state where they are rotated along the rotation direction around the rotation axis and combined with each other. Each of the terminal cover has a first cover member and a second cover member having a central side wall portion provided on the central side of the rotation locus when rotating along the rotation direction, and a tip side wall portion provided on the tip side of the rotation locus. A hinge that connects the first cover member and the second cover member so as to be openable and closable in the rotation direction, a central side hook portion provided on one of the central side wall portions of the first cover member or the second cover member, and a central side claw portion provided on the other central side wall portion of the first cover member or the second cover member. In the closed state, the central side hook portion is hooked on the central side claw portion to lock the first cover member and the second cover member with a central side locking mechanism. A tip side hook portion provided on one of the tip side wall portions of the first cover member or the second cover member, and a tip side claw portion provided on the other tip side wall portion of the first cover member or the second cover member. In the closed state, the tip side hook portion is hooked on the tip side claw portion to lock the first cover member and the second cover member together with the central side locking mechanism with a tip side locking mechanism. A guide mechanism provided for the tip side locking mechanism to guide the tip side hook portion along the rotation direction toward the tip side claw portion when the first cover member and the second cover member are rotated and combined along the rotation direction. The tip side locking mechanism is such that when the first cover member and the second cover member are rotated and combined along the rotation direction, if the tip side hook portion is not displaced in the axial direction along the rotation axis with respect to the tip side claw portion, the tip side hook portion is guided by the guide mechanism along the rotation direction toward the tip side claw portion. If the tip side hook portion is displaced in the axial direction with respect to the tip side claw portion, the tip side hook portion interferes with the guide mechanism. The central side locking mechanism is such that when the first cover member and the second cover member are rotated and combined along the rotation direction,Even when the central-side engaging portion is displaced in the axial direction with respect to the central-side claw portion, a movement space portion in which the central-side engaging portion is movable in the rotational direction is formed around the central-side claw portion.

Advantages of the Invention

[0008] In the terminal cover and the terminal with a cover according to the present invention, by guiding the tip-side engaging portion by the guide mechanism, the tip-side engaging portion can be smoothly locked to the tip-side claw portion. In this case, the terminal cover and the terminal with a cover are provided only for the tip-side locking mechanism without providing the guide mechanism for the central-side locking mechanism. Here, for example, when the guide mechanism is provided for the central-side locking mechanism, the central-side engaging portion is guided by the guide mechanism on the central side of the rotation locus of the first and second cover members. Therefore, in this case, compared with the case of guiding on the tip side of the rotation locus of the first and second cover members, the stroke until the guiding is short, so that it is difficult to align the positions during guiding, and there is a possibility that the workability is deteriorated. On the other hand, since the terminal cover and the terminal with a cover are provided only for the tip-side locking mechanism without providing the guide mechanism for the central-side locking mechanism, a long stroke can be ensured, whereby the alignment during guiding is easy and the workability can be improved.

Embodiments for Carrying Out the Invention

[0010] Embodiments for implementing the present invention will be described in detail with reference to the drawings. The present invention is not limited by the content described in the following embodiments. Further, the constituent elements described below include those that can be easily assumed by those skilled in the art and substantially identical ones. Furthermore, the configurations described below can be combined as appropriate. Also, various omissions, substitutions, or changes in the configuration can be made without departing from the gist of the present invention.

[0011] The covered terminal 100 according to the embodiment will be described with reference to the drawings. The covered terminal 100 is electrically connected, for example, as shown in FIGS. 1, 2, and 3, by being inserted into and fastened to a stud bolt of a device or an electrical connection component mounted on a vehicle, and electrically connects between devices.

[0012] In the following description, among the first direction, the second direction, and the third direction that intersect each other, the first direction is referred to as the "axial direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the axial direction X, the width direction Y, and the height direction Z intersect each other and are typically orthogonal. The axial direction X corresponds to a direction along the rotation axis P described later, an extending direction in which the electric wire W extends, etc. The width direction Y and the height direction Z correspond to intersecting directions that intersect the axial direction X. Also, each direction used in the following description represents the direction in a state where each part is assembled to each other unless otherwise specified.

[0013] The covered terminal 100 includes, for example, as shown in FIGS. 4 and 5, an electric wire with a terminal TW and a terminal cover 1.

[0014] The electric wire with a terminal TW has an electric wire W and a terminal T, and the terminal T is connected to the electric wire W.

[0015] The wire W is, for example, an insulated wire in which a plurality of metal strands having conductivity are bundled and covered with an insulating coating. Note that the wire W may be a bundle of a plurality of insulated wires. At at least one end of the wire W, the insulating coating is stripped off and the core wire is exposed from the insulating coating. The terminal T is connected to the core wire exposed from the insulating coating of the wire W.

[0016] The terminal T is, for example, a round (LA) terminal as shown in FIG. 4, and has a mating connection portion Ta and a crimping portion Tb. The mating connection portion Ta is provided on the tip side of the terminal T and is formed in an annular shape. The mating connection portion Ta is inserted into, for example, a stud bolt and tightened and fixed. The crimping portion Tb is provided on the base end side of the terminal T and is formed in a cylindrical shape. The core wire exposed from the end of the wire W is inserted into the crimping portion Tb, and the core wire is crimped and fixed to be electrically connected to the core wire. In this way, in the wire TW with a terminal, the terminal T and the wire W are electrically connected.

[0017] The terminal cover 1 is formed of an insulating resin and protects the electrical wire connection portion (connection portion) Tc between the wire W and the terminal T by housing it. The terminal cover 1 houses the terminal T, for example, with the mating connection portion Ta on the tip side of the terminal T exposed. More specifically, the terminal cover 1 houses the remaining portion of the terminal T excluding the mating connection portion Ta, that is, the portion including the wire connection portion Tc on the base end side of the terminal T. Further, the terminal cover 1 also houses the end portion of the wire W on the terminal T side, that is, the portion on the side connected to the wire connection portion Tc of the terminal T. The terminal cover 1 includes, for example, as shown in FIGS. 1, 2, and 5, a base member 10 as a first cover member, a lid member 20 as a second cover member, a hinge 30, a central side locking mechanism 40, a tip side locking mechanism 50, and a guide mechanism 60.

[0018] As shown in FIG. 5, the base member 10 has a housing portion 11, a wire opening 12, and a terminal opening 13.

[0019] The accommodating portion 11 is formed in a box shape and accommodates a portion including the wire connection portion Tc of the terminal T in the inner accommodating space portion. The accommodating portion 11 has a bottom wall 111, a central side wall portion 112, a tip side wall portion 113, a side wall 114, and a side wall 115.

[0020] The bottom wall 111 extends along the axial direction X and is a wall portion facing the lid member 20 in the height direction Z.

[0021] The central side wall portion 112 is provided on the central side of the rotation locus when the base member 10 rotates along the rotation direction R around the rotation axis P, extends along the axial direction X, and stands upright from the bottom wall 111 toward the lid member 20 along the height direction Z. That is, the central side wall portion 112 is a side wall portion inside the rotation of the base member 10. In other words, the central side wall portion 112 is a side wall portion closer to the hinge 30 side than the tip side wall portion 113. Here, the above-mentioned rotation axis P is an imaginary rotation axis when the base member 10 rotates around the hinge 30.

[0022] The tip side wall portion 113 is provided on the tip side of the rotation locus when the base member 10 rotates along the rotation direction R around the rotation axis P, extends along the axial direction X, and stands upright from the bottom wall 111 toward the lid member 20 along the height direction Z. That is, the tip side wall portion 113 is a side wall portion outside the rotation of the base member 10. In other words, the tip side wall portion 113 is a side wall portion on the side opposite to the hinge 30 side than the central side wall portion 112. The tip side wall portion 113 faces the central side wall portion 112 in the width direction Y.

[0023] The side wall 114 is a side wall provided between the central side wall portion 112 and the tip side wall portion 113. The side wall 114 is located closer to the wire W side than the side wall 115 in the axial direction X, extends along the width direction Y, and stands upright from the bottom wall 111 toward the lid member 20 along the height direction Z.

[0024] The side wall 115 is provided on the terminal T side of the side wall 114 in the axial direction X, extends along the width direction Y, and is a wall portion that stands upright from the bottom wall 111 toward the lid member 20 along the height direction Z. The side wall 115 faces the side wall 114 in the axial direction X.

[0025] In this way, the accommodating portion 11 is formed in a box shape by the bottom wall 111, the central side wall portion 112, the tip side wall portion 113, the side wall 114, and the side wall 115, and a accommodating space portion for accommodating the portion including the wire connection portion Tc of the terminal T is formed by these wall portions.

[0026] The wire opening 12 is an opening formed in the side wall 114 on the wire W side and is formed in a semicircular shape. The wire opening 12 forms a circular opening together with the wire opening 22 of the lid member 20 in the closed state where the base member 10 and the lid member 20 are combined with each other, and the wire W is inserted through this opening.

[0027] The terminal opening 13 is an opening formed in the side wall 115 on the terminal T side and is formed in a rectangular shape. The terminal opening 13 forms a rectangular opening together with the upper wall 211 of the lid member 20 in the closed state where the base member 10 and the lid member 20 are combined with each other, and the mating connection portion Ta of the terminal T is inserted along the axial direction X through this opening to expose the mating connection portion Ta.

[0028] As shown in FIG. 5, the lid member 20 has a cover portion 21 and a wire opening 22.

[0029] The cover portion 21 is formed in a plate shape and closes the opening of the accommodating portion 11 of the base member 10. The cover portion 21 has an upper wall 211, a central side wall portion 212, a tip side wall portion 213, and a side wall 214.

[0030] The upper wall 211 extends along the axial direction X and is a wall portion that faces the bottom wall 111 of the lid member 20 in the height direction Z. The upper wall 211 closes the opening of the accommodating portion 11 of the base member 10 in the closed state where the base member 10 and the lid member 20 are combined with each other.

[0031] The central side wall portion 212 is provided on the central side of the rotation locus when the lid member 20 rotates along the rotation direction R around the rotation axis P, extends along the axial direction X, and stands on the base member 10 side along the height direction Z from the upper wall 211. That is, the central side wall portion 212 is the side wall portion inside the rotation of the lid member 20. In other words, the central side wall portion 212 is the side wall portion closer to the hinge 30 than the tip side wall portion 213. The central side wall portion 212 overlaps with the central side wall portion 112 of the base member 10 along the width direction Y in the closed state where the base member 10 and the lid member 20 are combined.

[0032] The tip side wall portion 213 is provided on the tip side of the rotation locus when the base member 10 rotates along the rotation direction R around the rotation axis P, and is the side wall portion that stands on the base member 10 side along the height direction Z from the upper wall 211. That is, the tip side wall portion 213 is the side wall portion outside the rotation of the base member 10. In other words, the tip side wall portion 213 is the side wall portion on the side opposite to the hinge 30 side than the central side wall portion 112. The tip side wall portion 213 faces the central side wall portion 212 in the width direction Y. The tip side wall portion 213 overlaps with the tip side wall portion 113 of the base member 10 along the width direction Y in the closed state where the base member 10 and the lid member 20 are combined.

[0033] The side wall 214 is a side wall provided between the central side wall portion 212 and the tip side wall portion 213. The side wall 214 is located on the wire W side of the side wall 115 in the axial direction X, extends along the width direction Y, and stands on the lid member 20 side along the height direction Z from the upper wall 211.

[0034] The wire opening 22 is an opening formed in the side wall 214 on the wire W side, and is formed in a semi-circular shape. The wire opening 22 forms a circular opening together with the wire opening 12 of the base member 10 in the closed state where the base member 10 and the lid member 20 are combined with each other, and the wire W is inserted through this opening.

[0035] Note that the base member 10 and the lid member 20 are formed in an L shape according to the shape of the terminal T. The base member 10 has, for example, a main body portion along the axial direction X and a bent portion bent along the width direction Y according to the L shape. A hook portion 14 is provided on the side wall 116 of this bent portion. The lid member 20 has, according to the L shape, a main body portion along the axial direction X and a bent portion bent along the width direction Y. A claw portion 23 that is hooked on the hook portion 14 is provided on the side wall 216 of this bent portion.

[0036] The hinge 30 connects the base member 10 and the lid member 20 so as to be openable and closable in the rotation direction R. The hinge 30 has, for example, a belt-like shape and is formed to be elastically deformable. One end of the hinge 30 is connected to the central side wall portion 112 of the base member 10, and the other end is connected to the central side wall portion 212 of the lid member 20. The hinge 30 enables the base member 10 and the lid member 20 to be rotated along the rotation direction R to a closed state in which they are combined with each other and an open state in which the base member 10 and the lid member 20 are rotated along the rotation direction R to be opened from each other.

[0037] The central side locking mechanism 40 locks the base member 10 and the lid member 20 on the central side of the rotation locus when the base member 10 and the lid member 20 rotate along the rotation direction R around the rotation axis P. The central side locking mechanism 40 has a central side hook portion 41 and a central side claw portion 42.

[0038] The central side hook portion 41 is a frame-shaped hook. The central side hook portion 41 is provided on the central side wall portion 112 of the base member 10 and has a pair of arms 411, 411 and a bar member 412.

[0039] The pair of arms 411, 411 are each formed in an arm shape, extend along the height direction Z, and are arranged along the axial direction X and provided on the central side wall portion 112. A bar member 412 is provided between one arm 411 and the other arm 411 of the pair of arms 411, 411.

[0040] The bar member 412 extends along the axial direction X and is provided between the pair of arms 411, 411.

[0041] The central side claw portion 42 is a claw-shaped protrusion. The central side claw portion 42 is provided on the central side wall portion 212 of the lid member 20 and has an inclined surface 421 and a vertical surface 422.

[0042] The inclined surface 421 is formed to be inclined with respect to the height direction Z. When the base member 10 and the lid member 20 are rotated and combined, the inclined surface 421 abuts against the bar member 412 of the central side engaging portion 41 of the base member 10, making it easier for the bar member 412 to straddle the central side claw portion 42.

[0043] The vertical surface 422 is formed perpendicular to the height direction Z. When the base member 10 and the lid member 20 are rotated and combined, after the bar member 412 of the central side engaging portion 41 of the base member 10 straddles the inclined surface 421, the bar member 412 is locked.

[0044] The thus formed central side locking mechanism 40 locks the base member 10 and the lid member 20 by hooking the bar member 412 of the central side engaging portion 41 on the central side claw portion 42 in the closed state where the base member 10 and the lid member 20 are rotated along the rotation direction R and combined with each other.

[0045] The tip side locking mechanism 50 locks the base member 10 and the lid member 20 at the tip side of the rotation locus when the base member 10 and the lid member 20 rotate along the rotation direction R around the rotation axis P. The tip side locking mechanism 50 has a tip side engaging portion 51 and a tip side claw portion 52.

[0046] The tip side engaging portion 51 is a frame-shaped hook. The tip side engaging portion 51 is provided on the tip side wall portion 113 of the base member 10 and has a pair of arms 511, 511 and a bar member 512.

[0047] A pair of arms 511, 511 are each formed in an arm shape, extend along the height direction Z, and are arranged along the axial direction X and provided on the tip side wall portion 113. A bar member 512 is provided between one arm 511 and the other arm 511.

[0048] The bar member 512 extends along the axial direction X and is provided between the pair of arms 511, 511. 。

[0049] The tip side claw portion 52 is a claw-shaped protrusion. The tip side claw portion 52 is provided on the tip side wall portion 213 of the lid member 20 and has an inclined surface 521 and a vertical surface 522.

[0050] The inclined surface 521 is formed to be inclined with respect to the height direction Z. When the base member 10 and the lid member 20 are rotated and combined, the inclined surface 521 abuts against the bar member 512 of the tip side hook portion 51 of the base member 10, making it easier for the bar member 512 to cross over the tip side claw portion 52.

[0051] The vertical surface 522 is formed perpendicular to the height direction Z. When the base member 10 and the lid member 20 are rotated and combined, after the bar member 512 of the tip side hook portion 51 of the base member 10 crosses over the inclined surface 521, the bar member 512 is locked.

[0052] The tip side locking mechanism 50 formed in this way hooks the bar member 512 of the tip side hook portion 51 to the tip side claw portion 52 in the closed state where the base member 10 and the lid member 20 are rotated along the rotation direction R and combined with each other, and locks the base member 10 and the lid member 20 together with the center side locking mechanism 40.

[0053] The guiding mechanism 60 guides the tip-side engaging portion 51 along the rotation direction R toward the tip-side claw portion 52. The guiding mechanism 60 has a pair of guiding wall portions 61, 61. The pair of guiding wall portions 61, 61 are provided for the tip-side locking mechanism 50. The pair of guiding wall portions 61, 61 are each formed in a plate shape, for example, and are positioned on the tip-side wall portion 213 of the lid member 20 with the tip-side claw portion 52 sandwiched therebetween along the axial direction X, and are erected along the width direction Y from the tip-side wall portion 213. The distance between the pair of guiding wall portions 61, 61 in the axial direction X is set to a distance that can guide the tip-side engaging portion 51 inside. When the base member 10 and the lid member 20 are rotated and combined along the rotation direction R, the pair of guiding wall portions 61, 61 guide the tip-side engaging portion 51 along the rotation direction R toward the tip-side claw portion 52.

[0054] Incidentally, this guiding mechanism 60 is provided only for the tip-side locking mechanism 50 among the tip-side locking mechanism 50 and the center-side locking mechanism 40, and is not provided for the center-side locking mechanism 40. The reason is that, for example, when the guiding mechanism 60 is provided for the center-side locking mechanism 40, the center-side engaging portion 41 will be guided by the guiding mechanism 60 on the center side of the rotation trajectories of the base member 10 and the lid member 20. In this case, compared with the case of guiding on the tip side of the rotation trajectories of the base member 10 and the lid member 20, the stroke until guiding is shorter, so it is difficult to align the positions during guiding, and there is a risk that the workability will decrease.

[0055] When the base member 10 and the lid member 20 are rotated and combined along the rotation direction R, when the tip-side engaging portion 51 is not displaced in the axial direction X with respect to the tip-side claw portion 52, the pair of guiding wall portions 61, 61 guide the tip-side engaging portion 51 along the rotation direction R toward the tip-side claw portion 52, and the tip-side engaging portion 51 can be hooked on the tip-side claw portion 52 to lock the base member 10 and the lid member 20.

[0056] On the one hand, when the tip-side engaging mechanism 50 has the tip-side hooking portion 51 displaced in the axial direction X with respect to the tip-side claw portion 52, the tip-side hooking portion 51 interferes with the pair of guide wall portions 61, 61. When the tip-side engaging mechanism 50 has the tip-side hooking portion 51 interfere with the pair of guide wall portions 61, 61, the tip-side hooking portion 51 cannot be hooked on the tip-side claw portion 52, and the base member 10 and the lid member 20 cannot be engaged.

[0057] Here, as shown in FIG. 1, in the center-side engaging mechanism 40, a movement space portion Q is formed around the center-side claw portion 42. The movement space portion Q is, for example, a region formed on both sides of the center-side claw portion 42 in the axial direction X. When the base member 10 and the lid member 20 are rotated and combined along the rotation direction R, the movement space portion Q is a space portion that allows the center-side hooking portion 41 to move freely in the rotation direction R even when the center-side hooking portion 41 is displaced in the axial direction X with respect to the center-side claw portion 42. That is, the movement space portion Q is a space portion in which no interfering object is formed like the pair of guide wall portions 61, 61 when the center-side hooking portion 41 is displaced in the axial direction X with respect to the center-side claw portion 42. In other words, the center-side wall portion 212 of the lid member 20 is formed lower than the center-side claw portion 42 in the width direction Y for the range in which the center-side hooking portion 41 moves along the rotation direction R, thereby providing a movement space portion Q that allows the center-side hooking portion 41 to move freely in the rotation direction R.

[0058] When the center-side engaging mechanism 40 rotates and combines the base member 10 and the lid member 20 along the rotation direction R, and the center-side hooking portion 41 is not displaced in the axial direction X with respect to the center-side claw portion 42, the center-side hooking portion 41 can be hooked on the center-side claw portion 42 to engage the base member 10 and the lid member 20.

[0059] On the one hand, when the base member 10 and the lid member 20 are rotated and combined along the rotation direction R, even if the central side engaging portion 41 is displaced in the axial direction X with respect to the central side claw portion 42, since the movement space portion Q is formed around the central side claw portion 42, the central side engaging portion 41 can be hooked on the central side claw portion 42 to lock the base member 10 and the lid member 20.

[0060] As described above, the terminal cover 1 according to the embodiment includes a base member 10, a lid member 20, a central side locking mechanism 40, a tip side locking mechanism 50, and a guiding mechanism 60. The base member 10 and the lid member 20 can accommodate the wire connection portion Tc between the wire W and the terminal T in a closed state where they are rotated along the rotation direction R around the rotation axis P and combined with each other. Each has a central side wall portion 112, 212 provided on the central side of the rotation locus when rotating along the rotation direction R, and a tip side wall portion 113, 213 provided on the tip side of the rotation locus. The hinge 30 connects the base member 10 and the lid member 20 so as to be openable and closable in the rotation direction R. The central side locking mechanism 40 has a central side hook portion 41 provided on the central side wall portion 112 of the base member 10 and a central side claw portion 42 provided on the central side wall portion 212 of the lid member 20. In a closed state where the base member 10 and the lid member 20 are rotated along the rotation direction R and combined with each other, the central side hook portion 41 is hooked on the central side claw portion 42 to lock the base member 10 and the lid member 20. The tip side locking mechanism 50 has a tip side hook portion 51 provided on the tip side wall portion 113 of the base member 10 and a tip side claw portion 52 provided on the tip side wall portion 213 of the lid member 20. In a closed state where the base member 10 and the lid member 20 are rotated along the rotation direction R and combined with each other, the tip side hook portion 51 is hooked on the tip side claw portion 52 to lock the base member 10 and the lid member 20 together with the central side locking mechanism 40. The guiding mechanism 60 is provided for the tip side locking mechanism 50 and guides the tip side hook portion 51 along the rotation direction R toward the tip side claw portion 52 when the base member 10 and the lid member 20 are rotated and combined along the rotation direction R. In the above configuration, when the tip side locking mechanism 50 rotates the base member 10 and the lid member 20 along the rotation direction R and combines them, if the tip side hook portion 51 is not displaced in the axial direction X along the rotation axis P with respect to the tip side claw portion 52, the guiding mechanism 60 guides the tip side hook portion 51 along the rotation direction R toward the tip side claw portion 52. If the tip side hook portion 51 is displaced in the axial direction X with respect to the tip side claw portion 52, the tip side hook portion 51 interferes with the guiding mechanism 60.When the central locking mechanism 40 rotates and combines the base member 10 and the lid member 20 along the rotation direction R, even if the central hook portion 41 is displaced in the axial direction X with respect to the central claw portion 42, a movement space portion Q in which the central hook portion 41 is movable in the rotation direction R is formed around the central claw portion 42.

[0061] With this configuration, the terminal cover 1 can suppress interference between the tip-side hook portion 51 and the tip-side claw portion 52 by guiding the tip-side hook portion 51 by the guide mechanism 60, and can smoothly lock the tip-side hook portion 51 to the tip-side claw portion 52. In this case, the terminal cover 1 is provided only for the tip-side locking mechanism 50 without providing the guide mechanism 60 for the central locking mechanism 40. Here, for example, when the guide mechanism 60 is provided for the central locking mechanism 40, the central hook portion 41 will be guided by the guide mechanism 60 on the central side of the rotation locus of the base member 10 and the lid member 20. In this case, compared with the case of guiding on the tip side of the rotation locus of the base member 10 and the lid member 20, the stroke until guiding is short, so alignment during guiding is difficult and workability may decrease. On the contrary, since the terminal cover 1 is provided only for the tip-side locking mechanism 50 without providing the guide mechanism 60 for the central locking mechanism 40, a long stroke can be ensured, whereby alignment during guiding is easy and workability can be improved. Also, since the terminal cover 1 is provided with the guide mechanism 60 only for the tip-side locking mechanism 50, it is easier to confirm visually during work compared with the case of providing the guide mechanism 60 for the central locking mechanism 40, alignment during guiding can be facilitated, and workability can be improved.

[0062] As described above, in the terminal cover 1, since the guide mechanism 60 is provided only for the tip-side locking mechanism 50 among the tip-side locking mechanism 50 and the central locking mechanism 40, workability can be improved.

[0063] In the above terminal cover 1, the guiding mechanism 60 is erected at a position on the tip side wall portion 213 that sandwiches the tip side claw portion 52 along the axial direction X, and has a pair of guiding wall portions 61, 61 that guide the tip side engaging portion 51 to the tip side claw portion 52 along the rotation direction R. When the base member 10 and the lid member 20 are combined by rotating along the rotation direction R, if the tip side engaging portion 51 is displaced in the axial direction X with respect to the tip side claw portion 52, the tip side engaging portion 51 interferes with the pair of guiding wall portions 61, 61. With this configuration, the terminal cover 1 can suppress interference between the tip side engaging portion 51 and the tip side claw portion 52 by guiding the tip side engaging portion 51 with the pair of guiding wall portions 61, 61, and the tip side engaging portion 51 can be smoothly locked to the tip side claw portion 52. As a result, workability can be improved.

[0064] The terminal 100 with a cover includes the wire terminal TW with the terminal T connected to the wire W and the above terminal cover 1 that can accommodate the wire connection portion Tc between the wire W and the terminal T at the terminal T, so the workability can be improved.

[0065] In the above description, an example in which the central locking mechanism 40 has the central engaging portion 41 provided on the central side wall portion 112 of the base member 10 and the central claw portion 42 provided on the central side wall portion 212 of the lid member 20 has been described, but it is not limited to this. For example, the central claw portion 42 may be provided on the central side wall portion 112 of the base member 10, and the central engaging portion 41 may be provided on the central side wall portion 212 of the lid member 20.

[0066] Also, an example in which the tip side locking mechanism 50 has the tip side engaging portion 51 provided on the tip side wall portion 113 of the base member 10 and the tip side claw portion 52 provided on the tip side wall portion 213 of the lid member 20 has been described, but it is not limited to this. For example, the tip side claw portion 52 may be provided on the tip side wall portion 113 of the base member 10, and the tip side engaging portion 51 may be provided on the tip side wall portion 213 of the lid member 20. In this case, the pair of guiding wall portions 61, 61 are erected at a position on the tip side wall portion 113 of the base member 10 that sandwiches the tip side claw portion 52 along the axial direction X.

[0067] In addition, although the guiding mechanism 60 has been described as an example having a pair of guiding wall portions 61, 61 as a configuration example for guiding the tip-side engaging portion 51 to the tip-side claw portion 52, the tip-side engaging portion 51 may be guided to the tip-side claw portion 52 by other configurations different from the pair of guiding wall portions 61, 61.

[0068] In addition, although the terminal T has been described as an example of a round (LA) terminal, it is not limited thereto, and for example, it may be other terminals such as a split terminal having a U-shaped tip.
