Description

  The present invention relates to a protective member for protecting a terminal and an electric wire with a protective member including the same.

  Patent Document 1 discloses a cable terminal protector that temporarily protects a terminal of a terminal-attached electric wire.

Japanese Utility Model Publication No. 05-069824

  By the way, the wire harness for vehicles, such as a motor vehicle, may be mounted in a vehicle in the aspect containing the electric wire or components which become unnecessary depending on the vehicle mounted from a viewpoint of efficiency of a manufacturing process. Such a mounting mode is not desirable because the weight of the wire harness in the vehicle increases unnecessarily. In view of this, a method has been proposed in which an electric wire or a component that is unnecessary depending on the vehicle on which the wire harness is mounted is separately mounted later. In other words, a wire harness (common wire harness) that is commonly required between vehicles on which the wire harness is mounted is mounted on the vehicle, and a wire harness (optional wire harness) that is different depending on the vehicle is further mounted. Is the method.

  In the mounting method described above, the terminal of the terminal-attached electric wire in the option wire harness is exposed until the option wire harness is mounted on the vehicle. Therefore, when the option wire harness is mounted on the vehicle due to factors such as damage to the terminal due to external force, the terminal may not be properly inserted into the connector or the like.

  As a means for preventing such a situation, it is conceivable to temporarily protect the terminal by covering the terminal with a protective member until the terminal is inserted into a connector or the like.

  However, the cable terminal protector shown in Patent Document 1 is not intended to be attached and detached multiple times. When the cable terminal protector is attached to the terminal, the inner peripheral surface of the cable terminal protector comes into close contact with the entire outer peripheral surface of the terminal in an attempt to return to the original shape. For this reason, there is a concern that the work of removing the cable terminal protector from the terminal is troublesome.

  The electric wire with a protective member according to a tenth aspect includes the protective member according to any one of the first aspect to the ninth aspect, and an electric wire with a terminal including an electric wire and a terminal connected to an end of the electric wire. The terminal is clamped by the narrowed inner surface of the body portion of the main body portion in which the tension state is maintained by the tension maintaining portion.

  The electric wire with a protective member according to the eleventh aspect is an aspect of the electric wire with a protective member according to the tenth aspect.

<Embodiment>
With reference to FIGS. 1-6, the protection member 2 which concerns on embodiment, and the electric wire 100 with a protection member provided with the protection member 2 are demonstrated.

  1 and 2 are perspective views of the protection member 2. In addition, in FIG. 1, the electric wire 90 with a terminal containing the terminal 8 of the protection target of the protection member 2 is also shown. Moreover, in FIG. 2, the electric wire 100 with a protection member is shown. FIG. 3 is a cross-sectional view showing the protective member 2 in a natural state. FIG. 4 is a cross-sectional view showing the protective member 2 in a tensile state. The protection member 2 in the natural state and the protection member 2 in the tensile state will be described later. FIG. 5 is an enlarged view of a part of the protective member 2. FIG. 6 is a cross-sectional view of the protection member 2.

  First, the electric wire 90 with a terminal including the terminal 8 to be protected of the protective member 2 will be described. The terminal-attached electric wire 90 includes an electric wire 9 and a terminal 8 connected to the end of the electric wire 9.

  Here, as shown in FIG. 1, the electric wire 9 includes a core wire 91 and an insulating coating 92 that covers the periphery of the core wire 91. That is, here is a case where the electric wire 9 is an insulated wire. The core wire 91 is a metal conductor whose main component is copper or aluminum. The insulating coating 92 is an insulating member, for example, a synthetic resin member mainly composed of polyethylene or vinyl chloride.

  In the terminal-attached electric wire 90, the insulating coating 92 around the core wire 91 at the end of the electric wire 9 is removed. The terminal 8 is connected to the exposed core wire 91 after the insulation coating 92 is removed.

  The terminal 8 is a metal member whose main component is, for example, copper. Here, the terminal 8 includes a core wire connecting portion 81 connected to the core wire 91 at the end of the electric wire 9, a covering connecting portion 82 connected to the end of the insulating coating 92, and a mating side connected to the mating member. The connection part 83 and the intermediate part 84 which connects the other party connection part 83 and the core wire connection part 81 are provided. Here, from one end side to the other end side of the terminal 8, the covering connection portion 82, the core wire connection portion 81, the intermediate portion 84, and the mating side connection portion 83 are formed in this order. Details of each component will be described below.

  The counterpart connection portion 83 of the terminal 8 is a portion that can be connected to a counterpart member to which the terminal 8 is connected. Here, as shown in FIGS. It is formed in a rod shape. In this case, the counterpart member may be, for example, a female terminal including a recess into which the counterpart connection portion 83 is inserted. In addition, as another example, when the other party connection part 83 includes the recessed part into which a rod-shaped member can be inserted, or when the bolt fastening hole which enables bolt fastening with respect to the other party member is formed. Etc. are also conceivable.

  The core wire connecting portion 81 of the terminal 8 is a portion connected to the core wire 91 at the end of the electric wire 9. Here, the core wire connecting portion 81 includes a crimping piece that can be crimped to the core wire 91 at the end of the electric wire 9. In the terminal-attached electric wire 90, the crimping piece of the core wire connecting portion 81 is caulked in a state of covering the periphery of the core wire 91 at the end of the electric wire 9. As another example, it is of course conceivable that the core wire connecting portion is welded to the core wire 91 at the end of the electric wire 9 by ultrasonic welding or the like. In this case, it is conceivable that the core wire connecting portion is formed in a flat plate shape capable of welding the core wire 91 at the end of the electric wire 9.

  The covering connection portion 82 of the terminal 8 is a portion connected to an end portion of the insulating coating 92, and includes a crimping piece that can be crimped to the insulating coating 92. In the electric wire 90 with a terminal, the crimping piece of the covering connection portion 82 is caulked in a state of covering the periphery of the insulating coating 92.

  The intermediate portion 84 is a portion that connects the counterpart connection portion 83 and the core wire connection portion 81. As shown in FIG. 1, here, it is formed in a box shape. However, the intermediate portion 84 may have another shape such as a flat plate shape.

  In the present embodiment, the outer shape of the terminal-attached electric wire 90 is largest at the location of the covering connection portion 82 of the terminal 8. For this reason, in this embodiment, the terminal 8 and the protection member 2 are fixed mainly by the covering connection part 82 being clamped by the inner surface of the cavity part 23 of the protection member 2 mentioned later. Details will be described later. In addition, as another example, the case where the part with the largest external shape in the electric wire 90 with a terminal is places other than the covering connection part 82, such as the intermediate part 84, is also considered. In this case, it is conceivable that portions other than the covering connection portion 82 such as the intermediate portion 84 are sandwiched between the inner side surfaces of the cavity portion 23 of the protection member 2.

  Next, the protection member 2 will be described. The protection member 2 includes a main body portion 21 and a tension maintaining portion 22.

  At least one cavity 23 into which the terminal 8 connected to the end of the electric wire 9 is inserted is formed in the main body 21. Here, a case where a plurality of hollow portions 23 are formed in the main body portion 21 is shown.

  Moreover, the main-body part 21 is formed with elastic members, such as rubber | gum. For this reason, when an external force such as tension is applied, the main body portion 21 expands. Hereinafter, the direction in which the main body 21 extends is referred to as a tension direction.

  Here, the main body portion 21 is extended by applying a tensile external force to the main body portion 21 in a state where no external tension force is applied (hereinafter referred to as a main body portion 21 in a natural state). Hereinafter, the pulled and extended main body 21 is referred to as a main body 21 in a tensioned state.

  In the tensioned main body 21, the cavity 23 formed in the main body 21 is deformed so as to narrow in at least one direction orthogonal to the extending direction of the cavity 23 compared to the natural state. For this reason, if the main body part 21 is pulled in a state where the terminals 8 are accommodated in the hollow part 23 of the main body part 21 in the natural state, the hollow part 23 narrows. Thereby, the terminal 8 is pinched | interposed by the inner surface of the cavity part 23 which narrowed. More specifically, the cavity 23 is narrowed and the terminal 8 is sandwiched in a direction (hereinafter, referred to as a vertical direction) orthogonal to both the pulling direction of the main body 21 and the extending direction of the cavity 23. .

  And here, the said tension | pulling state is maintained by the tension | tensile_strength maintenance part 22 mentioned later. That is, the external tension force is continuously applied to the main body 21 by the tension maintaining unit 22. Thereby, the state in which the terminal 8 is sandwiched between the hollow portions 23 is maintained. Details will be described later.

  When the tensile external force applied to the main body portion 21 is removed, the main body portion 21 returns to its original shape. That is, when the maintenance of the tension state by the tension maintaining part 22 is released, the main body part 21 returns to the original shape. This is because the main body 21 is formed of an elastic member such as rubber. And if the main-body part 21 of a tension | pulling state returns to the main-body part 21 of a natural state, the cavity 23 which was narrowed will also return to the original magnitude | size. Thereby, it becomes easy to take out the terminal 8 from the cavity part 23 here.

  Next, the detail of the structure of the main-body part 21 is demonstrated.

  Here, the body portion 21 in the natural state is formed in a relatively thick rectangular parallelepiped shape. Then, when a tensile external force is applied to the main body portion 21, the main body portion 21 expands and deforms into a relatively thin rectangular parallelepiped shape, that is, a flat shape. Note that when the tensile external force is removed, the main body portion 21 returns from a flat shape to a rectangular parallelepiped shape.

  In the present embodiment, a plurality of hollow portions 23 are formed side by side along the pulling direction of the main body portion 21. That is, a plurality of hollow portions 23 are arranged along one direction (tensile direction). In this case, the terminals 8 accommodated in the plurality of cavities 23 can be collectively held on the inner surface of the cavity 23 only by pulling the main body 21 in one direction.

  Further, in this embodiment, the cavity portion 23 is at least one between the inner surface of the cavity portion 23 and the outer peripheral surface of the terminal 8 when the terminal 8 is inserted into the cavity portion 23 of the body portion 21 in the natural state. It is formed in a shape in which a gap is formed in the part. Here, as shown in FIG. 3, the cavity 23 is formed in a quadrangular shape with respect to the covering connection portion 82 of the terminal 8 having a circular cross section. In this case, as shown in FIG. 3, when the terminal 8 is inserted into the cavity portion 23 of the body portion 21 in the natural state, the inner surface of the cavity portion 23 other than the portion that contacts the bottom surface of the terminal 8 A gap is formed between the terminals 8. That is, a gap is formed between the inner side surface of the hollow portion 23 excluding the contact surface with the terminal 8 and the outer side surface of the terminal 8. In this case, the operation of inserting the terminal 8 into the cavity 23 can be easily performed.

  In addition, when the terminal 8 is inserted into the cavity portion 23 of the body portion 21 in the natural state, a case may be considered in which a portion other than the portion that contacts the bottom surface of the terminal 8 on the inner side surface of the cavity portion 23 contacts the terminal 8. It is done. Details will be described later.

  Moreover, in this embodiment, the several cavity part 23 formed in the main-body part 21 is the same magnitude | size. More specifically, the plurality of cavities 23 have the same shape. In this case, the main body 21 can be easily manufactured.

  Moreover, even if the several cavity part 23 formed in the main-body part 21 is the same magnitude | size, it is thought that the terminal 8 from which a magnitude | size and a shape differ can be hold | maintained favorably. That is, even if the size and shape of the terminal 8 inserted into each of the plurality of cavities 23 are different, the body portion 21 is pulled so that the cavities 23 of the same size are of the size of the terminals 8. Absorb differences and shape differences. For this reason, one type of cavity 23 can be used for a plurality of types of terminals 8. In this case, the versatility of the main body 21 is improved.

  In the present embodiment, the body portion 21 is formed with an opening 24 for inspecting an electrical connection state between the terminal 8 and the electric wire 9. As shown in FIGS. 1, 2, and 6, the opening 24 opposes in a direction (hereinafter, a vertical direction) perpendicular to both the pulling direction of the main body 21 and the extending direction of the cavity 23 in the main body 21. It is formed on one of the pair of outer surfaces 29. Hereinafter, for convenience, the outer surface 29 on the side where the opening 24 is formed is referred to as an upper surface 291. Further, the one of the pair of outer surfaces 29 where the opening 24 is not formed is referred to as a bottom surface 292.

  Here, a support portion 31 described later is provided on the bottom surface 292 side of the main body portion 21. On the other hand, the upper surface 291 of the main body 21 is a surface facing the outside. Here, in a state where the terminal 8 of the terminal-attached electric wire 90 is inserted into the hollow portion 23, a continuity inspection pin or the like is brought into contact with the terminal 8 from the outside through the opening 24, and the continuity inspection of the terminal-attached electric wire 90 is performed. be able to. As shown in FIG. 6, here, the intermediate portion 84 is formed in a box shape and has a relatively large external shape. Here, the intermediate portion 84 swells in the vicinity of the opening 24 in the inner surface of the cavity portion 23, and exists at a relatively close distance from the opening 24. For this reason, the intermediate portion 84 can be more reliably brought into contact by simply inserting a pin or the like for continuity inspection into the opening 24. That is, the continuity test can be performed easily and more reliably.

  Moreover, by forming the opening 24 in the upper surface 291, it is possible to suppress the opening 24 from being closed when the main body portion 21 is in a tensile state. That is, in this embodiment, the conduction inspection of the terminal-attached electric wire 90 can be more reliably performed.

  Further, here, the main body portion 21 is formed with a convex hook portion 32 to be described later and a concave portion 25 that can be hooked. Here, the recess 25 is a through-hole, more specifically, a through-hole penetrating in the vertical direction. In this case, the hook portion 32 described later is inserted from one side of the concave portion 25 toward the other side, whereby the concave portion 25 and the hook portion 32 are hooked. As another example, the case where the recess 25 is not a through hole but a recess is also conceivable.

  Moreover, in this embodiment, the one side edge part 26 of the main-body part 21 is being fixed to the support part 31 mentioned later in the tension | pulling direction. And the recessed part 25 is formed in the other side edge part 27 of the main-body part 21 in the tension | pulling direction. In this case, since the one side end portion 26 of the main body portion 21 is fixed to the support portion 31, the other side end portion 27 is held and pulled away from the one side end portion 26, and the recessed portion 25 is formed in the hook portion 32. By hooking, the main body portion 21 can be brought into a tensile state. That is, the main body 21 can be easily brought into a tension state.

  As another example, a case in which the concave portions 25 are provided in both the one-side end portion 26 and the other-side end portion 27 can be considered. In this case, the main body portion 21 has one side end portion 26 so that the one side end portion 26 is separated from the other side end portion 27, and has the other side end portion 27 so that the other side end portion 27 is on one side. It is conceivable that the main body 21 is pulled away from the end 26.

  Next, the tension maintaining unit 22 will be described. In the present embodiment, the tension maintaining part 22 includes a support part 31 and a hook part 32 formed on the support part 31.

  Here, the support portion 31 is provided on the bottom surface 292 side of the main body portion 21. As shown in FIGS. 1 and 2, here, a case where the support portion 31 is a plate-like member is shown. However, the support portion 31 may have a shape other than a plate shape.

  Further, the support portion 31 is made of a member that is less likely to be deformed than the main body portion 21. That is, the support portion 31 is formed of a member having higher rigidity than the main body portion 21. For example, it is conceivable that the support portion 31 is a resin member.

  The hook 32 formed on the support 31 is also made of a member that is less likely to be deformed than the main body 21.

  Further, here, one end portion 26 of the main body portion 21 is fixed to the support portion 31. For example, the case where the one side edge part 26 of the main-body part 21 and the support part 31 are being fixed with the adhesive agent can be considered. In addition, when the one side end portion 26 of the main body portion 21 and the support portion 31 are fixed by welding, or the one end portion 26 of the main body portion 21 is formed in a concave shape formed in the support portion 31. The case where the one side edge part 26 of the main-body part 21 and the support part 31 are being fixed is considered by being engage | inserted by this part.

  In addition, the part between the one side edge part 26 and the other side edge part 27 of the main-body part 21 is not being fixed to the support part 31. FIG. Therefore, the main body 21 can be deformed to be stretched by pulling the portion on the other side end 27 side away from the one side end 26.

  In the present embodiment, the support portion 31 is formed with a convex hook portion 32 that can be hooked into the concave portion 25. Here, as described above, since the one end portion 26 of the main body 21 is fixed to the support portion 31, the hook portion 32 is on the other side of the portion of the support 31 where the main body 21 is fixed. It is provided on the side end portion 27 side. More specifically, the hook portion 32 is provided in a portion of the support portion 31 opposite to the one end portion 26 side of the other end portion 27 of the main body portion 21 in the natural state.

  And in this embodiment, the main-body part 21 is comprised so that a several tension | tensile_strength state can be maintained selectively. More specifically, here, a plurality of hook portions 32 are formed on the support portion 31 along the tensile direction. Further, the plurality of hook portions 32 are formed side by side along the tensile direction at intervals.

  Here, a case where two hooking portions 32 are formed on the support portion 31 is shown. However, it is of course conceivable that three or more hooks 32 are formed on the support 31.

  Here, the object to be hooked in the recess 25 of the main body 21 is selected from the plurality of hooks 32. That is, the recess 25 is selectively hooked on the plurality of hooks 32. This case has the following advantages.

  That is, when the hook portion 32 at a position relatively close to the main body portion 21 in the natural state among the plurality of hook portions 32 is selected as the object to be hooked, the main body portion 21 does not expand relatively and the hollow portion 23 is not much. Does not narrow. In this case, for example, it is effective when a relatively gap is not formed between the inner surface of the cavity portion 23 of the main body portion 21 and the outer surface of the terminal 8. That is, when the relatively large terminal 8 is inserted into the cavity 23, the holding force suitable for the relatively large terminal 8 is prevented by not pulling the main body 21 in the natural state. Thus, the terminal 8 can be held between the inner surfaces of the cavity 23.

  On the other hand, when the hook 32 that is relatively far from the main body 21 in the natural state among the plurality of hooks 32 is selected as a target to be hooked, the main body 21 is relatively stretched and the cavity 23 is narrowed well. . In this case, for example, it is effective when a relatively gap is formed between the inner surface of the cavity 23 of the main body 21 and the outer surface of the terminal 8. That is, when the relatively small terminal 8 is inserted into the cavity 23, the relatively small terminal 8 is held between the inner surfaces of the cavity 23 by pulling the main body 21 in a natural state. it can.

  As described above, in the present embodiment, in consideration of the size of the terminal 8 inserted into the cavity portion 23 of the main body portion 21, the object to be hooked is selected from the plurality of hook portions 32 arranged along the pulling direction. By selecting, the clamping force by the inner surface of the cavity portion 23 of the main body portion 21 in the tensioned state can be made suitable for the terminal 8 inserted into the cavity portion 23. In this case, the terminal 8 is more stably held on the main body 21. Moreover, it can suppress that the excessive load is applied to the main-body part 21. FIG. Further, the number of types of terminals 8 that can be held by one main body 21 is increased, and the versatility is excellent.

  Here, at least one of the plurality of hooks 32 (here, all the hooks 32) is configured to be able to switch between a protruding form and a retracted form. Hereinafter, an example of the configuration will be described.

  In the present embodiment, as shown in FIGS. 1 and 5, the hook portion 32 is provided in an accommodation recess 33 formed in the support portion 31. The housing recess 33 is provided with a shaft portion that extends in a direction orthogonal to the extending direction of the housing recess 33 (coincident with the vertical direction). Here, the shaft portion is formed so as to extend in a direction orthogonal to both the extending direction (vertical direction) and the tensile direction of the accommodating recess 33 (coincident with the extending direction of the cavity portion 23), and after the hook portion 32. It penetrates the end part. For this reason, here, the hooking portion 32 is configured to be rotatable around the rear end portion as an axis.

  In the present embodiment, the hook portion 32 protrudes by the hook portion 32 being raised from the housing recess 33 so as to protrude from the main surface 39 on the main body portion 21 side of the support portion 31 to the main body portion 21 side. It becomes a form. Hereinafter, the protruding hook portion 32 is referred to as a protruding hook portion 32.

  Further, the hook 32 is housed in the housing recess 33 by rotating the tip of the projecting hook 32 to the housing recess 33 side. Hereinafter, this state is referred to as a retracting hook 32. Thereby, the hook part 32 does not protrude from the main surface 39 of the support part 31 to the main body part 21 side. Here, of the plurality of hooks 32, the hooks 32 other than the hooks 32 except for the hooks 32 that are hooked on the recesses 25 of the main body 21 are in a retracted form, so that the hooks 32 other than the hooks are in a tensioned state. It can suppress contacting the main-body part 21. FIG. Moreover, it can suppress that the hook part 32 other than a hook object obstructs the pulling operation | work of the main-body part 21. FIG.

  Moreover, in this embodiment, a tension | pulling state can be cancelled | released by applying force to the main-body part 21 with which the tension | tensile_strength maintenance part 22 maintained the tension | tensile_strength in a predetermined direction. In this case, the terminal 8 can be easily detached from the main body 21 only by applying a force in a predetermined direction. The specific configuration will be described below.

  Here, as shown in FIG. 5, the hook portion 32 is formed in a shape in which the tip portion is bent and has an inverted L shape. That is, the hook portion 32 includes a first portion 321 perpendicular to the main surface 39 of the support portion 31 and a second portion 322 extending in a direction intersecting the extending direction of the first portion 321 on the distal end side of the first portion 321. Contains.

  Therefore, here, the predetermined direction is a direction including a first direction along the extending direction of the first portion 321 and a second direction along the extending direction of the second portion 322. In this case, for example, by moving the concave portion 25 in the second direction and then moving in the first direction while the tensile state is maintained, the concave portion 25 is detached from the hooking portion 32 and the tensile state is released. Is done. As described above, the operation of removing the concave portion 25 from the hooking portion 32 can be easily performed manually. On the other hand, in order to release the tension state, it is necessary to move the recess 25 in two directions (first direction and second direction). For this reason, it can suppress that the recessed part 25 remove | deviates from the hook part 32 unexpectedly by vibration, for example during the transportation of this electric wire 100 with a protection member.

  The second direction coincides with the pulling direction of the main body 21. That is, the second direction is also a direction in which the main body portion 21 extends. Accordingly, when the recess 25 is removed from the hooking portion 32, the holding state of the terminal 8 is maintained by first moving the recess 25 along the second direction. And it has the following advantages by moving the recessed part 25 in order of the 2nd direction and a 1st direction, and removing from the hook part 32. FIG. First, when moving the recessed part 25 along a 2nd direction, holding | maintenance of the terminal 8 continues. And after that, the holding | maintenance of the some terminal 8 can be collectively cancelled | released here by moving the recessed part 25 along a 1st direction. That is, in the initial movement and midway of the releasing operation of the tension state (when the concave portion 25 is moved along the second direction), the holding of the terminal 8 can be stabilized, and then the concave portion 25 is aligned along the first direction. The movement of the plurality of terminals 8 can be released collectively by being moved. That is, since it is possible to suppress the terminal 8 from being removed from the cavity 23 during the initial operation and in the middle of the operation of removing the terminal 8 from the main body 21, the operation of removing the terminal 8 from the main body 21 is performed easily and stably. be able to.

  Further, here, in the hook portion 32 in the protruding form, the dimension from the main surface 39 of the support portion 31 to the second portion 322 is the thickness of the other side end portion 27 in which the recess 25 is formed (dimension in the vertical direction). Greater than or the same. In this case, when the hook portion 32 is passed through the concave portion 25, the second portion 322 is hooked on the opening edge portion of the concave portion 25, and the hook portion 32 is more difficult to be removed from the concave portion 25.

  Next, the operation | work which attaches the protection member 2 to the terminal 8 of the electric wire 90 with a terminal is demonstrated. Here, first, as shown in FIG. 1, the terminal 8 of the terminal-attached electric wire 90 is inserted toward the hollow portion 23 of the body portion 21 in the natural state.

  In the present embodiment, as shown in FIG. 3, the hollow portion 23 of the body portion 21 in the natural state is formed relatively large with respect to the terminal 8, and the inner surface of the hollow portion 23 and the outer peripheral surface of the terminal 8 are A relatively large gap is formed between the two. More specifically, in the present embodiment, in the main body portion 21 in the natural state, a pair of surfaces (here, both side surfaces) facing the inner surface of the cavity portion 23 and the terminal 8 in the pulling direction of the main body portion 21. A gap is formed between at least one (here, both). Further, in the body portion 21 in the natural state, of the pair of surfaces facing each other in the vertical direction perpendicular to both the pulling direction of the body portion 21 and the extending direction of the cavity portion 23 among the inner surface of the cavity portion 23 and the terminal 8. A gap is formed between at least one (here, the surface on the upper surface 291 side of the pair of surfaces of the terminal 8). Thus, in this embodiment, since the cavity part 23 is comparatively large with respect to the terminal 8, the terminal 8 can be easily inserted in the cavity part 23 of the main-body part 21 in a natural state.

  And the main-body part 21 of a natural state is pulled along the tension | pulling direction in the state in which the terminal 8 was inserted in the cavity part 23. FIG. As a result, as shown in FIGS. 2 and 4, the inner surface of the cavity 23 is deformed so as to be narrowed, and the terminal 8 is sandwiched between the inner surfaces of the cavity 23.

  And here, the recessed part 25 provided in the other side edge part 27 of the main-body part 21 in the state by which the main-body part 21 was pulled is predetermined | prescribed from the some hook part 32 provided in the support part 31. The hook 32 is hooked. Note that, here, the selected hooking portion 32 of the plurality of hooking portions 32 is in the protruding form, and the remaining hooking portions 32 are in the retracted form. Thereby, it is possible to prevent the hooking portions 32 other than the predetermined hooking portion 32 from interfering with the pulling operation of the main body portion 21.

  When the concave portion 25 is hooked on the predetermined hooking portion 32, the tension state of the main body portion 21 is maintained, and the state where the terminal 8 is sandwiched between the hollow portions 23 is maintained. Thereby, the electric wire 100 with a protective member in which the terminal 8 is sandwiched by the inner side surface of the narrowed cavity portion 23 of the main body portion 21 in which the tensile state is maintained by the tension maintaining portion 22 can be obtained.

  And the electric wire 90 with a terminal is conveyed with the electric wire 100 with a protection member. In this case, the terminal 8 is suppressed from being damaged before the terminal-equipped electric wire 90 is mounted on the vehicle.

  Next, an operation for removing the protective member 2 attached to the terminal 8 from the terminal 8 will be described. First, the hooked state between the recessed portion 25 of the main body portion 21 in the tensioned state and the hooking portion 32 of the support portion 31 is released. For example, the other end 27 of the tensioned main body portion 21 is supported by the operator, and the recessed portion 25 is removed from the hook portion 32, so that the hooked state between the concave portion 25 and the hook portion 32 is released. .

  Thereafter, the main body 21 formed of an elastic member returns from the shape in the tensioned state to the original shape in the natural state. Here, in the main body portion 21 in the natural state, as described above, a relatively large gap is formed between the inner surface of the cavity portion 23 and the outer peripheral surface of the terminal 8. For this reason, the terminal 8 can be easily taken out from the hollow portion 23 from the main body portion 21 in the natural state.

  And the electric wire 90 with a terminal taken out from the protection member 2 is further mounted in a vehicle as an option wire harness, for example.

<Effect>
In the present embodiment, the main body portion 21 is in a tensioned state, and the terminal 8 is sandwiched and supported by the inner surface of the narrow cavity portion 23. That is, the terminal 8 is clamped by the inner surface of the cavity 23 in a tension state, so that the main body 21 and the terminal 8 are fixed. In this case, the pinching of the terminal 8 by the inner surface of the hollow portion 23 of the main body portion 21 can be released by a simple operation of releasing the tension state. That is, the terminal 8 can be easily removed from the cavity 23 of the main body 21. That is, it becomes possible to easily remove the protective member 2 that protects the terminal 8 of the terminal-attached electric wire 90.

  Further, in this embodiment, the cavity portion 23 is at least one between the inner surface of the cavity portion 23 and the outer peripheral surface of the terminal 8 when the terminal 8 is inserted into the cavity portion 23 of the body portion 21 in the natural state. It is formed in a shape in which a gap is formed in the part. In this case, it is easy to insert the terminal 8 into the cavity 23 of the main body 21 in the natural state. That is, the operation of inserting the terminal 8 into the hollow portion 23 of the main body portion 21 can be performed more easily.

  Moreover, in this embodiment, since the cavity part 23 is formed in multiple numbers along the tension | pulling direction, the terminal 8 inserted in each of the some cavity part 23 by pulling the main-body part 21 along a tension | pulling direction. Can be held together. In this case, the operation of holding the plurality of terminals 8 between the hollow portions 23 of the main body portion 21 can be easily performed.

  Moreover, in this embodiment, the main-body part 21 can be made into a simple structure by providing the main-body part 21 with two or more hollow parts 23 of the same magnitude | size. In this case, even if the cavity portion 23 is the same size, the cavity portion 23 is deformed when the body portion 21 is pulled, and the difference in size and shape of the terminal 8 is absorbed by the cavity portion 23. be able to.

  In the present embodiment, the continuity of the terminal-attached electric wire 90 can be inspected through the opening 24 formed in the main body 21. Moreover, since the opening 24 is provided in one (here, upper surface 291) of a pair of outer side surfaces 29 which opposes in an up-down direction, when the main-body part 21 will be in a tension | pulling state, the opening 24 will close. Can be suppressed.

  In the present embodiment, the main body 21 is softer than the support 31. For this reason, the tension | pulling state of the main-body part 21 can be maintained with the simple structure of the recessed part 25 formed in the comparatively soft main-body part 21, and the convex hook part 32 formed in the comparatively hard support part 31. FIG.

  Moreover, in this embodiment, since the one side edge part 26 of the main-body part 21 is being fixed with the support part 31, the main-body part 21 can be made into a tension | pulling state only by pulling the other side edge part 27. FIG. That is, the operation of pulling the main body 21 can be easily performed.

  Moreover, in this embodiment, the main-body part 21 maintains a some tension | pulling state selectively. That is, the degree of narrowing of the hollow portion 23 can be a plurality of types. For this reason, this protective member 2 can hold and protect a relatively wide variety of terminals 8. That is, the versatility of the protective member 2 is improved.

  Moreover, in this embodiment, the versatility of the protection member 2 can be improved with a simple configuration in which a plurality of hook portions 32 are provided. Further, by retracting the hook portion 32 that is not used, it is possible to prevent the hook portion 32 that is not used from coming into contact with the main body portion 21 in the tension state. In this case, it is conceivable that the retracting hook 32 does not interfere with the pulling operation of the main body 21.

  Conventionally, it is necessary to insert the terminal at the end of the terminal-attached electric wire in a state where the opening of the cable protector having an inner shape smaller than the outer shape of the terminal is expanded, and the insertion work is troublesome. However, in the present embodiment, a gap is formed between the inner side surface of the inner surface of the cavity portion 23 excluding the installation surface with the terminal 8 and the outer side surface of the terminal 8. Thus, in the body portion 21 in the natural state, when the cavity portion 23 has a shape in which a relatively large gap is formed between the inner surface of the cavity portion 23 and the outer surface of the terminal 8, the terminal 8 is hollowed out. It becomes possible to perform the operation | work inserted in the part 23 more easily.

  Moreover, in this embodiment, when removing the protection member 2 from the terminal 8, the jig | tool for canceling | releasing fixation of the terminal 8 can be made unnecessary. That is, for example, when the terminal is fixed by the retainer of the connector housing, a retainer releasing jig for releasing the retainer is required. However, in the present embodiment, by releasing the hooked state between the hook portion 32 and the concave portion 25, the terminal 8 and the main body portion 21 can be fixed, and the jig and the like are unnecessary. it can.

<First Modification>
Next, the protective member 2A and the protective member-equipped electric wire 200 according to the first modification will be described with reference to FIGS. In the first modification, in the protection member 2A, the tension maintaining portion 22A is configured such that the main body portion 21 can selectively maintain a plurality of tension states. However, the configuration is different from the embodiment. FIG. 7 is a perspective view of the protective member 2A. FIG. 8 is a perspective view of the electric wire 200 with a protective member. FIG. 9 is a cross-sectional view of the protective member 2A. 7 to 9, the same components as those shown in FIGS. 1 to 6 are denoted by the same reference numerals.

  In this example, the main body 21 has the same configuration as that of the embodiment. Hereinafter, differences from the embodiment in the first modification will be described.

  As shown in FIG. 7, in this example, the support portion 31 is formed with one hook portion 32. Further, in this example, the support portion 31 is formed with a groove-shaped accommodation recess 33A along the tensile direction. The one hooking portion 32 is provided in the housing recess 33A and is configured to be movable along the tension direction in the housing recess 33A.

  This will be described more specifically. As shown in FIGS. 7 and 9, here, the hook portion 32 is supported by a pedestal portion 34 that can move in the accommodating recess 33 </ b> A along the pulling direction. For example, the pedestal 34 may be configured to be slidable on the bottom surface of the housing recess 33A, or may be configured to include a roller or the like that travels on the bottom surface of the housing recess 33A.

  Further, here, on the opposite side of the pedestal portion 34 to the hooking portion 32 side, a configuration for fixing the pedestal portion 34 at an arbitrary position in the accommodating recess 33A in the pulling direction is provided. Here, as shown in FIG. 9, a fastening hole 38 for fastening a bolt is formed on the side opposite to the hooking portion 32 side of the pedestal portion 34. A bolt 36 passed through the fastening hole 38 and a nut 37 for fixing the bolt 36 to the support portion 31 are provided. In this case, by loosening the nut 37, the bolt 36 can move with respect to the support portion 31, and the pedestal portion 34 can be moved in the accommodation recess 33A along the pulling direction. Thereby, the hook part 32 supported by the base part 34 can be moved along the pulling direction. When it is desired to fix the hook portion 32, the pedestal portion 34 is fixed by tightening the nut 37 and fixing the bolt 36 to the support portion 31. Thereby, the hook part 32 can be fixed to the support part 31.

  Here, as shown in FIG. 9, protrusions 35 are formed on both side surfaces of the housing recess 33 </ b> A to prevent the pedestal 34 from jumping out of the opening of the housing recess 33 </ b> A. Here, the pedestal 34 is provided on the bottom side of the projections 35 protruding from both side surfaces of the housing recess 33 </ b> A, and the pedestal 34 is prevented from moving upward from the projections 35.

  In this example, when the hook portion 32 is moved to a position relatively close to the main body portion 21 in the natural state and fixed at that position, the main body portion 21 in the tensioned state does not expand relatively and the cavity portion 23 is not so narrow. I wo n’t. In this case, for example, it is effective when a relatively gap is not formed between the inner surface of the cavity portion 23 of the main body portion 21 and the outer surface of the terminal 8. That is, when the relatively large terminal 8 is inserted into the cavity 23, the holding force suitable for the relatively large terminal 8 is prevented by not pulling the main body 21 in the natural state. Thus, the terminal 8 can be held between the inner surfaces of the cavity 23.

  On the other hand, when the hook portion 32 is moved to a relatively far position on the main body portion 21 in the natural state and fixed at that position, the main body portion 21 is relatively stretched and the cavity portion 23 is well narrowed. In this case, for example, it is effective when a relatively gap is formed between the inner surface of the cavity 23 of the main body 21 and the outer surface of the terminal 8. That is, when the relatively small terminal 8 is inserted into the cavity 23, the relatively small terminal 8 is held between the inner surfaces of the cavity 23 by pulling the main body 21 in a natural state. it can.

  In addition, since the operation | work etc. which remove 2 A of protection members from the terminal 8 are the same as that of embodiment, description is abbreviate | omitted.

  Also in this example, it is possible to easily remove the protective member 2A that protects the terminal 8 of the terminal-attached electric wire 90. Also in this example, the main body 21 selectively maintains a plurality of tensile states. That is, the degree of narrowing of the hollow portion 23 can be a plurality of types. For this reason, this protective member 2A can hold and protect a relatively wide variety of terminals 8. That is, the versatility of the protective member 2A is improved.

<Second Modification>
Next, the electric wire 300 with a protective member according to the second modification will be described with reference to FIGS. The second modification differs from the embodiment in that a large terminal 8B is inserted into the main body 21 in a natural state. 10 and 11 are sectional views of the protection member 2 and the terminal 8B in a natural state. In FIG. 10, the terminal 8B is indicated by a virtual line (two-dot chain line). In addition, in FIGS. 10 and 11, the same reference numerals are given to the same components as those shown in FIGS.

  In this example, the protection member 2 has the same configuration as the embodiment. Hereinafter, differences from the embodiment in this example will be described.

  In this example, as shown in FIG. 10, the dimension in the vertical direction of the cavity portion 23 of the main body portion 21 in the natural state is the outer diameter of the terminal 8B (here, the outer diameter of the location of the covering connection portion 82 of the terminal 8B). Smaller than).

  On the other hand, the dimension in the tensile direction of the cavity 23 of the main body 21 in the natural state is larger than the outer diameter of the terminal 8B. Therefore, in this example, in the main body portion 21 in the natural state, at least one of the pair of surfaces (here, both side surfaces) facing the inner surface of the cavity portion 23 and the terminal 8B in the pulling direction of the main body portion 21 (here, both sides). Then, a gap 40 is formed between them.

  The operation of inserting the terminal 8B into the cavity 23 in this example will be described. In this example, as shown in FIG. 10, the terminal 8B is relatively large. However, a gap 40 is formed between both the inner side surface of the cavity 23 and both side surfaces of the terminal 8B, so that there is a sufficient space. Here, the main body 21 is formed of an elastic member such as rubber. For this reason, for example, it is possible to deform | transform the part by the side of the upper surface 291 among the cavity parts 23 so that a part of clearance gap 40 may be located above the terminal 8B. Then, by deforming the portion of the cavity portion 23 on the upper surface 291 side and increasing the size in the vertical direction of the cavity portion 23 of the main body portion 21, the terminal 8B can be easily inserted into the cavity portion 23. .

  That is, in this example, the vertical dimension of the hollow portion 23 of the body portion 21 in the natural state is smaller than the outer diameter of the terminal 8B (here, the outer diameter of the location of the covering connection portion 82 of the terminal 8B). Even if it exists, it was formed between at least one (here, both) of a pair of surfaces (here both side surfaces) which oppose in the tension | pulling direction of the main-body part 21 among the inner surfaces of the cavity part 23, and the terminal 8B. By using the gap 40, the operation of inserting the terminal 8B into the cavity 23 can be easily performed.

  In addition, about the operation | work etc. which remove the protection member 2 from the terminal 8B, since it is the same as that of embodiment, description is abbreviate | omitted.

<Application example>
The structure of the tension maintaining part in which the tension state of the main body part is maintained may be a structure other than the catch between the recess 25 and the hook part 32. For example, the structure in which the tension state of the main body part is maintained by press-fitting a convex part provided on the main body part side into a concave part provided on the support part may be adopted. Moreover, the case where the tension | pulling state of a main-body part is maintained using a band etc. is also considered.

  Moreover, the hollow part formed in a main-body part may be one.

  Of course, the main body may be configured to maintain only one tension state. In this case, it is conceivable that one hook portion is formed in a state of being fixed to the support portion.

  Further, a case where a plurality of types of cavities are formed in the main body is also conceivable. That is, a case where a plurality of cavities of different sizes are formed in one main body is also conceivable.

  In addition, the protection member and the electric wire with the protection member according to the present invention can be freely combined with the above-described embodiments, modifications, and application examples within the scope of the invention described in each claim, or the embodiments. Each modified example and application example can be appropriately modified or partly omitted.
