  Reference numeral 1 in FIGS. 1 to 3 represents a protective cover of the present embodiment. The protective cover 1 protects the battery post 101 provided in the battery 100 and the exposed parts such as the battery terminal 110 electrically connected to the battery post 101 around the battery post 101. And avoids contact of other parts such as peripheral parts with respect to the battery post 101, the battery terminal 110, and the like. The protective cover 1 mainly provides insulation protection for the battery post 101, the battery terminal 110, and the like in accordance with avoidance of contact with other components.

  The protective cover 1 includes a cover body 10 and a connecting body 20 that are molded as separate pieces.

  First, the cover body 10 will be described.

  The cover body 10 is made of an insulating material such as a synthetic resin so as to cover the battery post 101, the battery terminal 110, and the electrical connection portion 121 (FIG. 1) of the electric wire 120 electrically connected to the battery terminal 110.

When the cover body 10 is attached to the battery 100, the battery post 101, the battery terminal 110, and the electrical connection portion 121 of the electric wire 120 are provided in the internal space. To be placed.

  The battery terminal 110 is formed of a conductive material such as metal and is physically and electrically connected to the battery post 101. For example, the battery terminal 110 is a combination of two terminal members (not shown) whose base material is a metal plate, and is integrated by connecting them physically and electrically. The battery terminal 110 is provided with a male screw member 111 protruding in the same direction as the battery post 101 (FIG. 1). The male screw member 111 is threadedly engaged with the female screw member 151, and the two terminal members are fastened together to physically and electrically connect them. In addition, the electric wire 120 may be directly and physically connected to the battery terminal 110 by the electrical connection part 121, or the electrical connection part 121 may be connected to the battery terminal 110 by a conductive member (not shown). In some cases, they are electrically connected indirectly. For this reason, in the latter case, the cover body 10 is formed so that the conductive member can be covered with the battery post 101 and the like. The electric wire 120 is drawn out of the cover body 10.

  For example, in the illustrated battery 100, a power connection system 130 is attached to the positive electrode side (FIG. 1). The power supply connection system 130 includes at least one electronic component (not shown) that is interposed between the battery post 101 and the electric wire 120 and electrically connected thereto. The electronic component may be the above-described conductive member itself or may have a conductive member. For example, the power supply connection system 130 includes at least one battery connection unit 140 having electronic components.

  The battery connection unit 140 is a connection unit connected to the battery 100, and includes an electronic component and a support member 141 (FIG. 1) that supports the electronic component. The support member 141 is formed of an insulating material such as a synthetic resin, and supports the electronic component inward. The illustrated battery connection unit 140 is configured as a fuse unit, and includes a protection circuit component (fuse circuit body) as an electronic component. The fuse circuit body has a fusible body on the energization path between the battery terminal 110 side and the electric wire 120 side. The fuse circuit body is fastened to the battery terminal 110 and is physically and electrically connected to the battery terminal 110. For this purpose, for example, the holding member 131 described later is provided with at least one male screw member 131 a that protrudes in the same direction as the battery post 101. The fuse circuit body and the battery terminal 110 are fastened together by inserting a male screw member 131a through each through hole (not shown) and screwing the female screw member 151 into the male screw member 131a. Further, the fuse circuit body is fastened together with the terminal 125 of the end of the electric wire 120 by screwing the male screw member 142 and the female screw member 152, and is electrically connected to the electric wire 120. The terminal 125 is formed of a conductive material such as metal and is physically and electrically connected to the electrical connection portion 121 of the electric wire 120 by crimping or the like. In this example, two battery connection units 140 are provided. Hereinafter, as necessary, one of the two battery connection units 140 is referred to as a first battery connection unit 140A, and the other is referred to as a second battery connection unit 140B. In this power connection system 130, the electronic component (fuse circuit body) of the first battery connection unit 140A is stacked on the battery terminal 110, and the electronic component (second battery connection unit 140B) (on the electronic component ( Fuse circuit bodies) are stacked. In FIG. 1, the illustration of the female screw member 152 related to the first battery connection unit 140A is omitted.

  The power connection system 130 includes a holding member 131 that holds the battery connection unit 140 (FIG. 1). The holding member 131 is formed of an insulating material such as synthetic resin, and is formed so that the battery terminal 110 can also be held. The holding member 131 is attached to the battery 100 by a fixing member 132 or the like.

  The illustrated cover main body 10 is formed so as to cover the power supply connection system 130 so that the battery post 101, the battery terminal 110, and the electric connection portion 121 of the electric wire 120 are covered. The cover body 10 is detachably attached to the battery 100 by a fitting portion (not shown) into which the battery post 101 is fitted, a lock mechanism 160 (FIG. 1) between the battery post 101 and the holding member 131 of the power connection system 130. Install. For example, the lock mechanism 160 includes a protruding portion 161 as a first engaging portion provided in the holding member 131 and a through hole 162 a into which the protruding portion 161 is inserted, and the attached cover body 10 is detached from the holding member 131. And a locking piece 162 (FIGS. 2 and 3) as a second engaging portion that locks the protruding portion 161 so as not to come off.

  Next, the connection body 20 will be described.

  The connecting body 20 connects the cover main body 10 to the electric wire 120 drawn out of the cover main body 10. For this reason, the cover main body 10 has the to-be-connected part 11 to which the coupling body 20 is connected. On the other hand, the coupling body 20 is connected to the connection portion 21 connected to the connected portion 11, the attachment portion 22 attached to the electric wire 120 drawn out of the cover body 10, and the connection portion connecting the connection portion 21 and the attachment portion 22. Part 23. The coupling body 20 is formed of an insulating material such as a synthetic resin. Moreover, in this connection body 20, the connection part 23 has flexibility, and the mutual positional relationship of the connection part 21 and the attachment part 22 can be changed.

  The connected portion 11 and the connecting portion 21 are formed so that they can be connected by changing the direction of attachment of the coupling body 20 to the cover body 10 in at least two directions. For example, one of the connected portion 11 and the connecting portion 21 is formed to have a piece-like piece portion in which a through hole is formed. The other of the connected portion 11 and the connecting portion 21 is formed to have two engaging legs inserted into the through hole. In the protective cover 1, the through holes and the shapes of the two engagement legs allow the connection of the coupling body 20 to the cover body 10 to be connected in at least two directions. Specific examples are shown below. Here, a through hole is provided in the connected portion 11 and an engaging leg is provided in the connecting portion 21.

  The illustrated connected portion 11 is a piece itself in which a through hole 11a (FIGS. 4 and 5) is formed, and is formed as a rectangular piece that protrudes from the outer wall surface of the cover body 10. Yes. The connected portion 11 is integrally formed with the cover body 10. The through hole 11a has a shape as if at least two long holes intersected. The long hole may be a long-angle hole or an oblong hole. For example, the through hole 11a corresponds to a plurality of long holes having the same shape arranged at an angle with respect to each other at the center of gravity. The illustrated through-hole 11a is formed by arranging two long-angle holes shifted 90 degrees from each other at the center of gravity, and forms a cross.

  The illustrated connecting portion 21 includes a rectangular flat base portion 21a and a hook-shaped clip (a so-called anchor clip) 21b protruding from one plane of the base portion 21a (FIGS. 4, 6 and FIG. 7). The clip 21b has a main shaft 21c that protrudes from one plane of the base portion 21a, and two engagement legs 21d that extend from the protruding end of the main shaft 21c. The engaging leg 21d extends from the tip of the main shaft 21c so as to be opposite to the protruding direction of the main shaft 21c and gradually away from the main shaft 21c. The engaging leg 21d has flexibility, and can be bent by approaching the main shaft 21c by applying a force toward the main shaft 21c. The respective engagement legs 21d are arranged to face each other so that the directions of bending thereof are opposite to each other.

  The engaging leg 21d is inserted into the through hole 11a while being bent by the pressing force from the side wall 11b (FIG. 5) of the short side of the long hole in the connected portion 11. Between the to-be-connected part 11 and the connection part 21, the mutual shape and magnitude | size of the through-hole 11a and the clip 21b are determined so that such a bending may be performed in an elastic region. In the clip 21b, each engaging leg 21d is bent while being pressed by the side walls 11b facing each other. Furthermore, the engagement leg 21d returns its shape to the direction of eliminating the bending upon completion of insertion into the through hole 11a. For this reason, between the to-be-connected part 11 and the connection part 21, the mutual shape and magnitude | size of the through-hole 11a and the clip 21b so that the movement to the cancellation | release direction of such bending may be performed by the engagement leg 21d. Decide.

The engaging leg 21d is a first locked member capable of locking the connected portion 11 (one portion) in a direction opposite to the insertion direction into the through hole 11a along with the movement in the direction in which the bending is eliminated. It has a portion 21d ₁ (FIGS. 6 and 8). The first locked portion 21d ₁ faces the plane of the connected portion 11 (one portion) (on the side opposite to the plane facing the base portion 21a) upon completion of insertion of the engaging leg 21d into the through hole 11a. Therefore, it can be locked in the plane. Accordingly, since the clip 20b can be prevented from coming off from the inserted through hole 11a, the connecting body 20 can be kept held by the connected portion 11.

In addition, the engaging legs 21d has a connected part 11 second latched capable engaged on the side wall of the through hole 11a in the (single unit) section 21d ₂ with movement of the resolved direction of the deflection (FIGS. 6 and 8). Its second engaged portion 21d ₂ are disposed to face the side wall of the through hole 11a with complete insertion into the through hole 11a of the engaging legs 21d. For example, the second engaged portion 21d ₂ includes a wall portion facing the side wall 11b of the short side of the long hole in the connecting portion 11, a side wall portion facing the long sides the side walls of the long holes in the connected part 11, have. The interval between the opposing walls is set so that the rotation of the clip 21b with the insertion direction as an axis is suppressed. Thereby, since the connection body 20 can maintain the insertion state to the through-hole 11a of the clip 21b, the position shift of the connection part 21 with respect to the cover main body 10 can be suppressed.

  The clip 21b illustrated here can be pulled out from the through hole 11a by bending each engaging leg 21d toward the main shaft 21c after the insertion into the through hole 11a is completed. That is, the connected portion 11 (one piece) and the connecting portion 21 are formed to be detachable from each other. Therefore, even if the operator wrongly attaches the connecting body 20 to the cover body 10, the connecting body 20 can be attached in the correct orientation.

  For example, the illustrated connected portion 11 (one portion) protrudes from two orthogonal outer wall surfaces (first and second outer wall surfaces 10a and 10b) in the cover body 10, and 2 of the four sides. One is blocked (FIGS. 4 and 5). For this reason, in this illustration, the connection body 20 can be attached to two directions with respect to the to-be-connected part 11 (one piece). The connecting body 20 can also be attached to the cover body 10 in the first connection form shown in FIG. 2, and attached to the cover body 10 in the second connection form (FIG. 3) shifted by 90 degrees with respect to the first connection form. You can also. In addition, this connection part 11 (one part) can change the attachment direction of the connection body 20 to three directions by arrange | positioning so that it may protrude from one outer wall surface in the cover main body 10, for example. . In addition, the connected portion 11 (one portion) protrudes from the outer wall surface of the cover main body 10 via, for example, the legs, and is arranged so that the outer wall surface of the cover main body 10 does not exist around the four sides. Thus, it is possible to change the mounting direction of the connecting body 20 in four directions.

The attachment portion 22 has a flexible U-shaped main body 22a (FIGS. 6 to 8). In the main body 22a, the electric wire 120 is inserted inward from the U-shaped opening. The free end of the two Katakarada 22a ₁ in the main 22a, is provided with a claw portion 22b which face each other (FIG. 8). Each of the claw portion 22b, so as to close the opening of the U-shaped in principal 22a, are protruded from each of Katakarada 22a _1. The space | interval of the nail | claw part 22b is set so that it may become narrower than the outermost diameter of the electric wire 120 inserted inside the main body 22a.

The attachment portion 22 inserts the electric wire 120 inward of the main body 22a while pressing the two claw portions 22b against the electric wire 120 on the U-shaped opening side of the main body 22a. In the attachment portion 22, each piece 22 a ₁ bends while increasing the distance between the claws 22 a _{1 as} the claws 22 b are pressed against the electric wires 120, and the distance between the claws 22 b is the outermost diameter of the electric wires 120. Then, the electric wire 120 enters the inside of the main body 22a. And this attachment part 22 returns to the original shape, when insertion of the electric wire 120 is completed. Mounting portion 22, in this way attached to the wire 120, unless spread each interval of Katakarada 22a _1, can continue maintaining the inserted state of the electric wire 120.

  The connecting portion 23 is a long object formed in a rectangular thin plate shape, and the connecting portion 21 and the attaching portion 22 are integrally formed at both ends in the longitudinal direction. The illustrated connecting portion 23 is formed so that it can be bent in various directions including twisting.

  Here, in the battery 100, two electric wires 120 are drawn out from the first battery connection unit 140A and the second battery connection unit 140B, respectively, through different routing paths. For example, when the connecting body 20 is attached to the electric wire 120 of the second battery connecting unit 140B, the connecting body 20 is attached to the cover body 10 in the first connection form described above, and after the protective cover 1 is attached to the battery 100, The attachment part 22 is attached to the electric wire 120 (FIGS. 9 to 11).

  Thus, the protective cover 1 attached with respect to the battery 100 removes the cover main body 10 from the battery 100, for example, when performing the maintenance of the power supply connection system 130 (FIG. 12). In that case, the cover main body 10 is connected to the electric wire 120 via the connecting body 20, and can be stopped at a predetermined position as in the related art. Accordingly, since the protective cover 1 is prevented from dropping to a position where the operator's fingers cannot reach when the cover main body 10 is detached from the battery 100, the cover main body 10 is attached to the original position. Is easy.

  On the other hand, when attaching the connecting body 20 to the electric wire 120 of the first battery connecting unit 140A, the connecting body 20 is attached to the cover body 10 in the second connection form shown above, and after the protective cover 1 is attached to the battery 100, The attachment part 22 is attached to the electric wire 120 (FIG. 13).

  As described above, the protective cover 1 of the present embodiment can change the mounting direction of the connecting body 20 with respect to the cover body 10, so that it corresponds to the routing route of the electric wire 120 drawn out from the cover body 10. By attaching the connecting portion 21 of the connecting body 20 to the cover main body 10 in such a direction, the attaching portion 22 of the connecting body 20 can be attached to the electric wire 120. Therefore, even if this protective cover 1 is a case where the wiring route of the electric wire 120 differs according to the specification of the vehicle, for example, by changing the mounting direction of the coupling body 20 with respect to the cover main body 10, The connection body 20 can be attached to the electric wire 120, and sharing by each specification is attained. Furthermore, the protective cover 1 can be attached to the cover body 10 in consideration of the arrangement of other parts around the battery 100 due to the variability of the mounting direction of the connection body 20 with respect to the cover body 10. Therefore, it is possible to attach the connecting body 20 to the electric wire 120 so as not to interfere with other parts. Therefore, for example, even if the arrangement of the other parts differs depending on the vehicle specifications, the protective cover 1 can be changed to other parts according to the respective specifications by changing the mounting direction of the connecting body 20 with respect to the cover body 10. The connecting body 20 can be attached to the electric wire 120 so as not to interfere with each other, and sharing with each specification becomes possible. Thus, the protective cover 1 of the present embodiment does not need to be prepared as a dedicated product for each vehicle specification and has high versatility. For example, the management of parts during vehicle assembly is simplified, and as a result The cost of the vehicle can be reduced.

  Moreover, the protective cover 1 of this embodiment can shape | mold the cover main body 10 and the coupling body 20 with a respectively different metal mold | die. For this reason, the protective cover 1 can be downsized as compared with the case where the cover main body and the connecting body are integrally formed as in the prior art. Further, since the protective cover 1 can form the connecting body 20 having the thin-walled portion (the connecting portion 23) with a mold different from the cover body 10, the molten resin material in the mold of the cover body 10. The fluidity of each mold can be improved, and the shape and molding conditions of each mold can be simplified. For this reason, this protective cover 1 can improve the yield as compared with the conventional case.
