Description

[Technical field]

[0001] The present invention relates to a shield structure. [Background technology]

[0002] A wide variety of electronic devices are mounted in automobiles, and wire harnesses are arranged to transmit power, control signals, etc. to the electronic devices. The wire harness includes a plurality of electric wires and connectors, and is connected to the electronic devices and other wire harnesses by fitting the connectors to the connectors of the electronic devices or the connectors of other wire harnesses.

[0003] In such a wire harness, a shield structure is known that is attached to two shielded cables that handle high voltages, such as in electric vehicles (EVs) and hybrid electric vehicles (HEVs) (see, for example, Patent Document 1). One example of the shield structure includes a housing that accommodates a terminal-equipped electric wire, the end of which is connected to a terminal, and a cylindrical shield shell into which the housing is inserted. The housing is configured to have a pair of divided bodies that sandwich the electric wire between them. One of the pair of divided bodies is provided with a locking portion, and the other is provided with a lock receiving portion that can be engaged with the locking portion, and the pair of divided bodies are configured to maintain a state in which the electric wire is sandwiched between them by engaging the locking portion with the lock receiving portion.

[0004] When assembling such a shielding structure, the electric wires are sandwiched between the pair of halves constituting the housing, and in a locked state where the locking portion is engaged with the lock receiving portion, the pair of halves are inserted into the inside of a jig, and after it is confirmed (detected) that the pair of halves is in the locked state, they are housed in the shielding shell. In this manner, the shielding structure is assembled. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2023-57199 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the conventional shield structure, a jig is used to detect whether the pair of segments is in a locked state, which requires the expense of preparing the jig and the work of detecting whether the pair of segments is in a locked state, resulting in high manufacturing costs.

[0007] An object of the present invention is to provide a shield structure which reduces manufacturing costs. [Means for solving the problem]

[0008] In order to solve the problem and achieve the object, the invention described in claim 1 is a shielding structure supported at a predetermined position of an electric wire, comprising: a cylindrical shielding shell having a shielded space; and a housing that holds the electric wire and is inserted into the shielded space, wherein the shielding shell has a guide structure that guides the housing into the shielded space, and the housing has a pair of halves that sandwich and hold the electric wire, and a locking mechanism for maintaining a state in which the pair of halves hold the electric wire, the locking mechanism having a locking portion provided on one of the pair of halves and a lock receiving portion provided on the other of the pair of halves that is engageable with the locking portion, and wherein the housing is guided by the guide structure as the housing is inserted into the shielded space, thereby causing the pair of halves to approach each other and causing the locking portion and the lock receiving portion to engage with each other. Effect of the Invention

[0009] According to the invention described in claim 1, it is possible to reduce the manufacturing cost. [Brief description of the drawings]

The shield structure 1 constitutes a wire harness arranged in an automobile or the like, and constitutes a shield circuit that shields electrical noise leaking to the outside from an electric wire 10 that transmits a control signal or the like, or electrical noise flowing in from the outside.

[0012] 1 and 2, a shielding structure 1 of this embodiment is supported at a predetermined position for a pair of electric wires 10 (electric wires, shown in FIG. 1) and fixed to a metallic mounting target in a vehicle body to form a shielding circuit, and includes a cylindrical shielding shell 2 having a shielded space 20 (shown in FIG. 2), a housing 3 (shown in FIG. 1) that holds the pair of electric wires 10, 10 and is inserted into the shielded space 20, and a shell-side guide portion 4 (guiding structure, shown in FIG. 2) that is provided on the shielding shell 2 and guides the housing 3 into the shielded space 20. A terminal connector (not shown) is connected to each of the ends (rear ends, the end on the near side in FIG. 1) of the pair of electric wires 10, 10.

[0013] In the following, the axial direction of each of the pair of electric wires 10, 10 may be referred to as the "front-rear direction" and indicated by the "arrow Y", the direction in which the pair of electric wires 10, 10, 2 are arranged may be referred to as the "left-right direction" and indicated by the "arrow X", and the direction perpendicular to the arrows X and Y and in which the pair of divided bodies 31A, 31B sandwich the electric wire 10 may be referred to as the "height direction" and indicated by the "arrow Z". In addition, in the arrow Y, one end side of the electric wire 10 (the back front side in FIG. 1) may be referred to as the "front Y1", and the opposite side may be referred to as the "rear Y2". In addition, in the arrow Z, one side may be referred to as the "upper Z1" and the other side may be referred to as the "lower Z2".

[0014] The shielded shell 2 is formed by pressing and bending a conductive metal plate. As shown in Fig. 2, the shielded shell 2 includes a shell body 21 that forms a shielded space 20, a cylindrical portion 22 that continues to the front Y1 of the shell body 21, a plate-shaped vehicle body fastening portion 23 (extension plate) that is provided to continue to the rear Y2 of the shell body 21 and is fastened to an attachment target (not shown) with a bolt, a locked portion 24 that is locked to a locking arm 314 provided on the housing 3 (described later), and a shell-side guide portion 4 that guides the housing 3 into the shielded space 20.

[0015] As shown in FIG. 2, the shell body 21 has an upper wall 21A (first wall), a bottom wall 21B (second wall), and a pair of side walls 21C, 21D, and is equipped with a storage section body 210 formed in a rectangular cylindrical shape with the axis in the front-to-rear direction Y to define the shielded space 20, and a blocking wall 211 located at the rear end of the storage section body 210 to fill the gap with the tubular section 22.

[0016] The height dimension (inner diameter dimension from top wall 21A to bottom wall 21B) L0 (shown in FIG. 2) of this shell body 21 is configured to be greater than the height dimension when the housing 3 described below is in an engaged state, and is configured to be smaller than the height dimension when the housing 3 is in a disengaged state.

[0017] 2, the vehicle body fastening portion 23 is configured in a plate shape extending in the front-rear direction Y and the left-right direction X, and is provided continuous with the bottom wall 21B of the shell main body 21 via a lower guide portion 41, which will be described later. The vehicle body fastening portion 23 is provided with a bolt insertion hole 230 through which a bolt (not shown) is inserted.

[0018] As shown in Fig. 2, the locked portions 24 are provided on the bottom wall 21B of the shell main body 21, and are provided in pairs with a gap in the left-right direction X. Each locked portion 24 includes a cut edge 24A formed by cutting out the bottom wall 21B, and is configured to have a bulging portion 24B that bulges upward Z1 toward the shielded space 20, and a hole 24C provided in front Y1 of the cut edge 24A. The cut edge 24A constitutes the front edge of the bulging portion 24B. This bulging portion 24B is provided continuously in the front-rear direction Y, and its rear end is provided in the vehicle body fastening portion 23, and its front end (cut edge 24A) is provided in the bottom wall 21B of the shell main body 21, straddling a lower guide portion 41 that constitutes the shell side guide portion 4 described later.

[0019] As shown in FIG. 2, the shell side guide portion 4 includes an upper guide portion 40 (first guide portion) and a lower guide portion 41 (second guide portion).

[0020] The upper guide portion 40 is provided on the rear end edge of the upper wall 21A of the shell main body 21, and is configured to have a first guide surface that slopes downward Z2 as it proceeds forward Y1. In other words, the upper guide portion 40 has a tapered shape formed by cutting out the rear end edge of the shell main body 21. This upper guide portion 40 is provided at a position away from the vehicle body fastening portion 23 in the front-rear direction Y, with the lower guide portion 41 in between. In addition, the upper guide portion 40 is provided at a position where it abuts against an upper abutment portion 60 (shown in FIG. 3) of the housing 3, which will be described later, of the housing 3 when the lower guide portion 41 pushes up the housing 3.

[0021] The lower guide portion 41 is located at a step between the bottom wall 21B of the shell main body 21 and the vehicle body fastening portion 23, and is configured with a second guide surface that slopes upward Z1 (inward of the shielded space 20) as it proceeds forward Y1.

[0022] As shown in FIGS. 3 and 4, the housing 3 has a pair of electric wire insertion portions 30, 30 (shown in FIG. 3) through which the pair of electric wires 10, 10 are respectively inserted, and includes an upper division body 31A and a lower division body 31B (a pair of division bodies) that sandwich and hold the pair of electric wires 10, 10, a locking mechanism 5 (shown in FIG. 4) provided on one side surface of the upper division body 31A and the lower division body 31B in the left-right direction X, and a hinge 32 (shown in FIG. 3) provided on the other side surface of the pair of division bodies 31A, 31B in the left-right direction X to connect the pair of division bodies 31A, 31B to each other.

[0023] The upper divisional body 31A and the lower divisional body 31B are each configured in a block shape. The upper divisional body 31A and the lower divisional body 31B have divisional faces 310a, 310b extending in directions perpendicular to the top and bottom (XY directions), respectively, and are configured so that the electric wire 10 inserted into the electric wire insertion portion 30 described below is held in a state in which the divisional faces 310a, 310b are in contact with each other.

[0024] As shown in Fig. 3, each wire insertion portion 30 has a pair of grooves 30A, 30B formed by cutting out the dividing surfaces 310a, 310b of the pair of divisional bodies 31A, 31B, respectively, into groove shapes extending in the front-rear direction Y. Hereinafter, one of the pair of grooves 30A, 30B may be referred to as the "upper groove 30A," and the other of the pair of grooves 30A, 30B may be referred to as the "lower groove 30B." The upper groove 30A is provided in the upper divisional body 31A, and the lower groove 30B is provided in the lower divisional body 31B.

[0025] As shown in FIG. 3, the upper split body 31A comprises an upper split body main body 310A having an upper groove portion 30A formed in the upper split surface 310a, a pair of upper electric wire support portions 311A, 311A ​​that are continuous with the upper groove portion 30A of the upper split body main body 310A and extend forward Y1 to support a pair of electric wires 10, 10, respectively, and an upper connecting portion 312A that connects the pair of upper electric wire support portions 311A, 311A.

[0026] As shown in Figures 3 and 6, the lower split body 31B includes a lower split body main body 310B having a lower groove portion 30B formed in a lower split surface 310b, a lower wire support portion 311B that is continuous with the lower groove portion 30B of the lower split body main body 310B and is assembled to the upper wire support portion 311A ​​to support each of a pair of electric wires 10, 10, a one-side support portion 313B that is continuous with the lower groove portion 30B of the lower split body main body 310B and extends rearward Y2 to support one of the electric wires 10, and a locking arm 314 (shown in Figure 6) that locks the locked portion 24 of the shield shell 2.

[0027] 1 and 3, the lower division body main body 310B is provided with an insertion portion 315 through which the locked portion 24 provided on the shell body 21 is inserted. As shown in Fig. 6, the insertion portion 315 is located below Z2 of the lower groove portion 30B, and is formed in the shape of a groove extending in the front-rear direction Y on the lower surface of the lower division body main body 310B (the surface that can come into contact with the bottom wall 21B of the shell body 21).

[0028] As shown in Figures 6 and 7, the locking arm 314 is formed by cutting out the wall portion 300 located between the lower groove portion 30B and the insertion portion 315 and is configured to include an arm body 316 extending forward Y1, and a locking protrusion 317 provided at the free end of the arm body 316 for locking with the locked portion 24 (cut edge 24A).

[0029] As shown in FIGS. 4 and 5, the lock mechanism 5 includes a lock portion 5A provided on the upper divisional body 31A, and a lock receiving portion 5B provided on the lower divisional body 31B that engages with the lock portion 5A.

[0030] The locking portion 5A is configured in a U-shape and includes a pair of extending portions 51, 51 extending in the up-down direction Z and arranged side by side in the front-rear direction Y, and a connecting portion 52 connecting the lower ends of the pair of extending portions 51, 51. The locking portion 5A is configured so as to be movable toward and away from the left-right direction X. The upper end of the locking portion 5A is fixed to one side surface of the upper divided body 31A in the left-right direction X, and the lower end is provided so as to protrude downward Z2 from the divided surface 310a of the upper divided body 31A.

[0031] The lock receiving portion 5B is formed of a protrusion protruding from one side surface of the lower divided body 31B in the left-right direction X. This lock receiving portion 5B is configured to be positioned inside the U-shape of the locking portion 5A, i.e., inside the pair of extension portions 51, 51 and the connecting portion 52, when the upper divided body 31A and the lower divided body 31B approach each other and the divided surfaces 310a, 310b come into contact with each other. In this embodiment, the state in which the lock receiving portion 5B is positioned inside the U-shape of the locking portion 5A is referred to as an "engaged state in which the locking portion 5A and the lock receiving portion 5B are engaged with each other," and in the engaged state, the pair of divided bodies 31A, 31B maintain a state in which they hold the electric wire 10.

[0032] As shown in FIG. 4, the housing 3 is provided with an upper contact portion 60 (contact portion) that contacts the upper guide portion 40 of the shield shell 2, and a lower contact portion 61 that contacts the lower guide portion 41 of the shield shell 2.

[0033] 4, the upper abutment portion 60 is provided at a corner located at the boundary between the top surface and the front surface of the upper divided body 31A, and is configured to have a taper that tapers downward Z2 as it proceeds forward Y1. The taper of this lower abutment portion 61 is configured to be an inverse taper to the inclination (taper) of the upper guide portion 40 of the shield shell 2. As a result, the upper abutment portion 60 is configured to abut and slide against the upper guide portion 40 as the housing 3 is moved forward Y1.

[0034] 4, the lower contact portion 61 is provided at a corner located at the boundary between the underside and front sides of the lower half 31B, and is configured to have a taper that extends upward Z1 as it advances forward Y1. The lower contact portion 61 is configured to slide along the lower guide portion 41 as the housing 3 moves forward Y1.

[0035] Next, a procedure for assembling the shield structure 1 having the above-mentioned configuration will be described with reference to Figures 1 and 3 to 7. In Figures 6 and 7, the electric wires 10 are omitted.

[0036] First, the pair of electric wires 10, 10 are inserted into the shield shell 2 with the vehicle body fastening portion 23 facing rearward Y2. Then, the housing 3 is positioned rearward Y2 of the shield shell 2, and predetermined positions of the electric wires 10 are placed in the upper groove portion 30A (or the lower groove portion 30B) of the upper division body 31A (or the lower division body 31B) of the housing 3, and each electric wire 10 is fixed to the upper division body 31A (or the lower division body 31B) using tape or a cable tie.

[0037] Then, the upper divisional body 31A is displaced (moved) so as to approach the lower divisional body 31B. As the displacement of the upper divisional body 31A progresses, the tip of the locking portion 5A provided on the upper divisional body 31A comes into contact with the lock receiving portion 5B of the lower divisional body 31B. As the displacement progresses, the locking portion 5A comes into contact with the lock receiving portion 5B, and the locking portion 5A bends and rides up the lock receiving portion 5B. As the displacement progresses further, the locking portion 5A rides up the lock receiving portion 5B, and the locking portion 5A returns to its natural state. At approximately the same time, the divisional surfaces 310a, 310b of the upper divisional body 31A and the lower divisional body 31B come into contact with each other, and each electric wire 10 is inserted into each electric wire insertion portion 30, and the lock receiving portion 5B is positioned inside the U-shape of the locking portion 5A, that is, inside the pair of extension portions 51, 51 and the connecting portion 52, as shown in FIGS. 4 and 5. In this manner, the housing 3 is in an engaged state in which the lock portion 5A is engaged with the lock receiving portion 5B. In this engaged state, the pair of divided bodies 31A, 31B maintains a state in which the electric wire 10 is sandwiched and held therebetween, as shown in FIG.

[0038] Thereafter, the housing 3 (in an engaged state) is moved forward Y1 relative to the shielded shell 2. As the movement progresses, the lower contact portion 61 of the housing 3 comes into contact with the lower guide portion 41 of the shielded shell 2. As the movement progresses further, as shown in FIG. 7, the lower contact portion 61 slides on the inclination of the second guide surface of the lower guide portion 41 and rides up the lower guide portion 41, and the housing 3 is inserted into the shielded space 20 of the shielded shell 2. As the movement progresses further, the locking arm 314 of the housing 3 locks the locked portion 24 of the shielded shell 2. This prevents the housing 3 from coming off the shielded shell 2. In this manner, the assembly of the shielded shell 2 is completed.

[0039] Next, with reference to Figures 6 and 7, we will explain the case where the housing 3 is inserted into the shielded space 20 of the shielded shell 2 in a disengaged state, i.e., in a state (disengaged state) in which the lock receiving portion 5B is not positioned inside the U-shape of the locking portion 5A, i.e., inside the pair of extension portions 51, 51 and the connecting portion 52.

[0040] The housing 3 (in a non-engaged state) is moved forward Y1 relative to the shield shell 2. As the movement progresses, the lower contact portion 61 of the housing 3 comes into contact with the lower guide portion 41 of the shield shell 2. As the movement progresses further, the lower contact portion 61 slides against the inclination of the lower guide portion 41 and rides up the lower guide portion 41, as shown in FIG. 6. At substantially the same time, the upper contact portion 60 of the housing 3 comes into contact with the upper guide portion 40 of the shield shell 2. As the movement progresses further, the upper contact portion 60 slides against the inclination of the first guide surface of the upper guide portion 40, and the upper divided body 31A is pressed against the lower divided body 31B. As a result, the lock portion 5A approaches the lock receiving portion 5B, and the lock receiving portion 5B is positioned inside the U-shape of the lock portion 5A, that is, inside the pair of extension portions 51, 51 and the connecting portion 52. In this way, the housing 3 is brought into an engaged state in which the locking portion 5A is engaged with the lock receiving portion 5B, and is permitted to be inserted into the shielded space 20 as shown in Fig. 7. As the movement continues, the locking arm 314 of the housing 3 locks the locked portion 24 of the shielded shell 2. This prevents the housing 3 from being removed from the shielded shell 2. In this way, the assembly of the shielded structure 1 is completed.

[0041] Thereafter, the shield structure 1 is bolted to the vehicle body fastening portion 23. In this manner, a shield circuit is formed that blocks electrical noise leaking to the outside from the electric wire 10 that transmits a control signal or the like, or electrical noise flowing in from the outside.

[0042] According to the embodiment described above, as the housing 3 is inserted into the shielded space 20, the housing 3 is guided by the shell side guide portion 4 (guiding structure) so that the pair of halves 31A, 31B approach each other and the lock portion 5A and the lock receiving portion 5B engage with each other. This makes it possible to omit the cost of preparing a jig and the work of checking (detecting) whether the pair of halves 31A, 31B are engaged, as in the conventional technology, and therefore reduces manufacturing costs.

[0043] Moreover, the shell side guide portion 4 (guiding structure) has an upper guide portion 40 (first guide portion), which is provided on the top wall 21A (first wall) and is configured to have a first guide surface that is inclined so as to protrude toward the bottom wall 21B (second wall) as it proceeds forward Y1 (insertion direction in which the housing 3 is inserted into the shielded space 20). With this, when the housing 3 is in a disengaged state, the housing 3 slides along the inclination of the first guide surface that constitutes the upper guide portion 40, and one of the pair of divided bodies 31A, 31B is pressed against the other, thereby realizing a configuration in which the pair of divided bodies 31A, 31B approach each other and are inserted into the shielded space 20 in an engaged state in which the lock portion 5A is engaged with the lock receiving portion 5B.

[0044] Further, the shell side guide portion 4 (guiding structure) has a lower guide portion 41 (second guide portion), which is provided between the bottom wall 21B (second wall) and the vehicle body fastening portion 23 (extending plate), and is configured to have a second guide surface that is inclined so as to protrude toward the upper wall 21A (first wall) as it proceeds forward Y1 (insertion direction in which the housing 3 is inserted into the shielded space 20). With this, when the housing 3 is in a disengaged state, the housing 3 slides on the inclination of the second guide surface constituting the lower guide portion 41, and rides up the second guide surface, so that the other of the pair of divided bodies 31A, 31B is pressed against one of them, and the pair of divided bodies 31A, 31B approach each other, thereby realizing a configuration in which the housing 3 is inserted into the shielded space 20 in an engaged state in which the lock portion 5A is engaged with the lock receiving portion 5B.

[0045] Moreover, the housing 3 has an upper abutment portion 60 (abutment portion) on the upper divided body 31A (one of the pair of divided bodies 31A, 31B) that can abut against the upper guide portion 40 (first guide portion), the upper guide portion 40 being provided on the side away from the vehicle body fastening portion 23 (extension plate) with the lower guide portion 41 (second guide portion) in between, and the upper guide portion 40 being provided at a position where the upper abutment portion 60 abuts when the housing 3 is guided by the lower guide portion 41. This shifts the timing at which the housing 3 abuts against the lower guide portion 41 and the upper guide portion 40 of the shield shell 2, and a configuration can be realized in which the housing 3 can be smoothly inserted into the shielded space 20 with a small force even in a disengaged state.

[0046] Further, the inner dimension L0 of the shell main body 21 in the direction in which the pair of divided bodies 31A, 31B sandwich the electric wire 10 is configured to be smaller than the inner dimension L0 in the disengaged state in which the locking portion 5A and the lock receiving portion 5B of the housing 3 are not engaged with each other, and larger than the inner dimension L0 in the engaged state in which the locking portion 5A and the lock receiving portion 5B are engaged with each other. This makes it possible to prevent the housing 3 from being inserted into the shielded space 20 in the disengaged state.

[0047] In addition, the best configurations and methods for implementing the present invention are disclosed in the above description, but the present invention is not limited thereto. That is, the present invention has been mainly illustrated and described with reference to specific embodiments, but those skilled in the art can make various modifications to the above-described embodiments in terms of shape, material, quantity, and other detailed configurations without departing from the scope of the technical idea and purpose of the present invention. Therefore, the descriptions limiting the shapes, materials, etc. disclosed above are illustrative descriptions for the purpose of facilitating understanding of the present invention, and do not limit the present invention, and therefore descriptions of the names of components that are free of some or all of the limitations on the shapes, materials, etc. are included in the present invention.
