Description

This invention relates to an attachment part that is attached to a wire harness that is arranged on a vehicle body and is formed, for example, of a bundle of electric wires, an electric wire bundle with an attachment part, a wire harness, an exterior-mounted wire harness, and a method for manufacturing a wire harness.

2. Description of the Related Art Automobiles and other vehicles are equipped with numerous electrical components. These electrical components are connected to other electrical components and power supplies via wire harnesses, which are bundles of insulated electric wires, to form electrical circuits.
As disclosed in Patent Document 1, a wire harness is formed by bundling a plurality of covered electric wires, and is formed with a main trunk line and a plurality of branch wires branching off from the trunk line. The branch wires are formed by bending one of the plurality of electric wires at a predetermined position, or by placing a part of another electric wire along the trunk line. The roots of the branch wires are then wrapped and fixed with tape. However, in order to perform this positioning with precision, it is very time-consuming to measure the bending position each time, and efficient manufacturing has not been possible.

In addition, since the number and position of the branch wires vary depending on the vehicle model, its specifications, and destination, it was even more difficult to manufacture a wide variety of wire harnesses efficiently and with high precision.

Japanese Patent Application Laid-Open No. 1-283708

In view of the above-mentioned problems, the present invention aims to provide an attachment part, a wire bundle with attachment part, a wire harness, an armored wire harness, and a method for manufacturing a wire harness that can efficiently manufacture a high-precision wire harness.

The present invention is an attachment part that is attached to a longitudinal intermediate portion of an electric wire bundle, and is provided with: a main body portion that clamps the electric wire bundle and has higher rigidity than the electric wire bundle; and a tightening portion that tightens the main body portion that clamps the electric wire bundle in a clamping direction, and the tightening portion is composed of a band portion that wraps around an outer periphery of the electric wire bundle and a buckle portion that fixes the band portion in a state where it is wrapped around the outer periphery of the electric wire bundle, and is characterized in that the main body portion is provided with mounting grooves on both sides in the longitudinal direction and in a direction perpendicular to the clamping direction, the mounting grooves being concave and extending in the clamping direction, and fitting with ribs provided on an exterior part that exteriors a wire harness formed by assembling a plurality of the electric wire bundles.

According to the present invention, a wire harness can be efficiently manufactured with high precision.
In detail, a predetermined position in the longitudinal direction of the electric wire bundle is clamped by a main body having higher rigidity than the electric wire bundle, and the main body clamping the electric wire bundle is clamped in the clamping direction by a fastening part composed of a band part that is wound around the outer periphery of the electric wire bundle and a buckle part that fixes the band part in a state where it is wound around the outer periphery of the electric wire bundle, thereby making it possible to fix the attachment part at the predetermined position of the electric wire bundle with high accuracy. Therefore, by using an electric wire bundle with an attachment part attached at a bending position, it is not necessary to measure the position each time, and it is possible to efficiently configure a wire harness having branch wires with high accuracy.

In addition, by attaching a mounting part whose main body is more rigid than the flexible wire bundle to the wire bundle, a highly rigid portion can be provided to the flexible wire bundle. Therefore, the mounting part for the flexible wire bundle can be held by the chuck of the manufacturing device, and the manufacturing of the wire harness can be automated.

In one aspect of the invention, the main body may be composed of a pair of clamping parts that clamp the wire bundle from both sides in the cross-sectional direction, and a hinge part that connects the pair of clamping parts to each other so that they can pivot in the clamping direction.

This invention allows the pair of clamping parts to be integrated by the hinge part, reducing the number of parts and allowing the mounting part to be attached to the specified position of the wire bundle more efficiently than when multiple parts are assembled to clamp the wire bundle.

In another embodiment of the present invention, at least one of the opposing surfaces of the pair of clamping parts may be provided with a fitting groove that penetrates in a direction parallel to the pivot axis of the hinge part and into which the bundle of electric wires fits.

With this invention, the wire bundle is fitted into a fitting groove provided on at least one of the opposing opposing surfaces of the clamping portion, and the pair of clamping portions are pivoted in the clamping direction by the hinge portion, so that the wire bundle is clamped by the clamping portion and the mounting component is fixed to the wire bundle.

In addition, since the fitting groove penetrates the opposing surfaces of the clamping section in a direction parallel to the pivot axis of the hinge section, the mounting component can be accurately mounted in a direction perpendicular to the axial direction of the wire bundle fitted into the fitting groove.

In another aspect of the invention, the tightening portion may be disposed in a middle portion of the main body in the longitudinal direction, the band portion may extend along a direction perpendicular to the clamping direction and the longitudinal direction, and a winding space in which the band portion winds the electric wire bundle may be formed in the middle portion of the main body in the longitudinal direction.

The band portion winding the electric wire bundle as described above means that the band portion is wound around the outer periphery of the electric wire bundle. The band portion may be wound around the outer periphery of a single electric wire bundle, or the band portion may be wound around multiple electric wire bundles together.

According to this invention, the wire bundle can be fastened by the fastening portion in the winding space provided in the longitudinal intermediate portion of the main body, thereby making it possible to reliably fix the mounted component to a predetermined position of the wire bundle.
In detail, in the winding space formed in the middle part of the longitudinal direction of the main body, the band portion extending along the clamping direction and an orthogonal direction perpendicular to the longitudinal direction winds the bundle of electric wires, so that the band portion can be wound around the bundle of electric wires clamped by the main body along a cross-sectional direction perpendicular to the longitudinal direction.

In addition, because the winding space in which the band portion winds the bundle of electric wires is formed in the middle part of the main body portion, the bundle of electric wires can be fixed more stably than when the band portion winds and fixes the bundle of electric wires near the longitudinal end of the main body portion.

The present invention is also characterized in that the bundle of electric wires is provided with the above-mentioned attachment part attached to a predetermined position in the longitudinal direction of the bundle of electric wires.
According to the present invention, it is possible to form a wire bundle with mounting components accurately attached at predetermined positions in the longitudinal direction.

Furthermore, the present invention is characterized in that it provides a wire harness formed by assembling a plurality of the above-mentioned electric wire bundles with attachment parts.
Furthermore, the present invention is characterized in that it is a manufacturing method for a wire harness, comprising: attaching the above-mentioned attachment part to a predetermined position in a longitudinal direction of the electric wire bundle to form an electric wire bundle with attachment parts; and assembling a plurality of the electric wire bundles with attachment parts to form a wire harness.
According to the present invention, a wire bundle having mounting parts accurately attached at predetermined positions in the longitudinal direction can be assembled, thereby efficiently configuring a high-precision wire harness.

In a further aspect of the present invention, a branch wire may be formed by bending the electric wire in the vicinity of the mounting portion where the mounting component is mounted.
According to the present invention, a branch line can be formed from electric wires bent near the mounting location where the mounting component is mounted at a predetermined position of the electric wire bundle with high accuracy. Therefore, the branch line can be formed efficiently and with high accuracy compared to the case where the position to bend the electric wire is measured each time, the electric wire is bent, and the branch line is fixed with tape.

The present invention is also characterized in that the armored wire harness is provided with an exterior part that armors a plurality of assembled electric wire bundles with mounting parts, and the mounting parts are fixed to the exterior part.
The exterior components include protectors and corrugated metals having a groove-shaped, square U-shaped, L-shaped or rectangular cross section.

This invention allows a flexible bundle of electric wires to be fixed in a precise position relative to the exterior component using a highly rigid mounting component. In addition, the branch wires extending from the exterior component can be precisely bent, with the bending point being near the mounting component that is precisely mounted in a predetermined position.

As a further aspect of the present invention, the mounting component may be configured such that a rib provided on the exterior component fits into the mounting groove.
According to the present invention, the branch wire can be accurately led out from the exterior component.

This invention provides mounting parts, wire bundles with mounting parts, wire harnesses, exterior-mounted wire harnesses, and methods for manufacturing wire harnesses that can efficiently manufacture high-precision wire harnesses.

The wire bundle with a link 1 is composed of a long wire bundle 10 and a branch link 20 attached and fixed to a predetermined position in the longitudinal direction of the long wire bundle 10.
The electric wire bundle 10 is configured by bundling a plurality of insulated electric wires, each of which has a conductor covered with an insulating coating, and has appropriate flexibility. In the present embodiment, the electric wire bundle 10 is illustrated as a single mass, but the insulated electric wires constituting the electric wire bundle 10 are not integrated with each other. However, the electric wire bundle 10 may be configured by bundling electric wires in which a plurality of insulated electric wires are integrated, such as twisted pair electric wires, or may be configured by including a part of the insulated electric wire bundle 10.

The branch piece 20 is a mounting part that is mounted to the longitudinal center portion of the electric wire bundle 10, and is configured in a substantially cubic shape.
More specifically, the branching piece 20 is configured in a generally cubic shape, with side blocks 21 arranged on both sides in the width direction when viewed from the front, and connecting portions 60 that connect the side blocks 21 to each other.
The branch block 20 is made of a resin having higher rigidity than the electric wire bundle 10 .

The upper and lower ends of the side blocks 21 are provided with recessed mounting grooves 23 that extend in the left-right direction when viewed from the side (in the front-rear direction when viewed from the front).
An attachment hole 22 that penetrates the branch block 20 in the width direction when viewed from the front is formed near the center of the side block 21 when viewed from the side. The above-mentioned connecting portion 60 is provided above the attachment hole 22. A buckle 61 is provided on the rear side of the connecting portion 60 when viewed from the front (on the left side when viewed from the left side).

The buckle 61 has an insertion hole 62 that penetrates the buckle 61 from the front to the rear when viewed from the front (left to right when viewed from the side) and into which the band 40 described below is inserted, and the insertion hole 62 has a restriction mechanism (not shown) that restricts slack in the inserted band 40.

Between the lateral blocks 21 arranged at a predetermined interval in the width direction when viewed from the front, the connecting portion 60 is provided with a band 40 extending downward, and below the connecting portion 60 and on the front side when viewed from the front (right side in the left side view), a winding space 70 is formed in which the band 40 is wound around the bundle of wires 10 passing through the mounting hole 22.
The band 40 is flexible and generally strip-shaped, and is formed with a length approximately three times the vertical length of the branching piece 20 .

The branching piece 20 thus configured is made up of a clamping block 30 arranged in the front rear direction when viewed from the front (left and right direction when viewed from the side) and a hinge 50 that pivotally connects the clamping blocks 30 (31, 32).
As shown in Figures 3 and 4, the clamping block 30 includes a first block 31 and a second block 32 which form the front view shape of the branching piece 20. In this embodiment, the first block 31 is on the rear side when viewed from the front (left side when viewed from the left side), and the second block 32 is on the front side when viewed from the front (right side when viewed from the left side).

The first block 31 and the second block 32 are both formed into an inverted U-shape when viewed from the front, with side parts 33 constituting the lateral blocks 21 and connecting parts 34 arranged on both sides in the width direction when viewed from the front. In addition, the upper and lower ends of each side part 33 are provided with a concave mounting groove component 35 that constitutes the mounting groove 23 and extends in the left-right direction when viewed from the side (front-rear direction when viewed from the front).

A fitting recess 36 that extends in the left-right direction when viewed from the front (front-rear direction when viewed from the side) and constitutes the mounting hole 22 is provided in the center of the vertical direction on the opposing surfaces of the first block 31 and the second block 32. Therefore, the clamping block 30 (31, 32) is formed in a roughly C-shape when viewed from the side, with the opposing sides open.

The first block 31 also includes a hinge 50 that pivotally connects the lower end of the side portion 33 of the first block 31 to the lower end of the side portion 33 of the second block 32. The hinge 50 includes two connecting bands 51 that connect the side portions 33. The first block 31 and the second block 32 connected by the hinge 50 configured in this manner can be opened so that the connecting bands 51 extend, as shown in FIG. 4(b), and can pivot so that the connecting bands 51 are folded back. In other words, the first block 31 and the second block 32 connected by the hinge 50 configured with the connecting bands 51 can pivot around a virtual pivot axis L in the width direction when viewed from the front (the pivot direction shown by the arrow in FIG. 3(b) and FIG. 4(c)).

The connecting portion 34 of the first block 31 is configured with a buckle 61 , and the band 40 extends downward from below the buckle 61 .
The connecting portion 34 of the second block 32 constitutes the front portion of the connecting portion 60 when viewed from the front, and has a communication hole 37 that communicates with the insertion hole 62 of the buckle 61 in the first block 31 in the folded state.

The clamping block 30 (31, 32) configured in this manner pivots by folding back the hinge 50 around the pivot axis L as the pivot center, forming a branching piece 20 in a folded-back state in an approximately cubic shape, with the fitting recess 36 provided in the clamping block 30 forming the mounting hole 22 and the mounting groove forming portion 35 forming the mounting groove 23.

A method for mounting the branch block 20 thus configured to the wire bundle 10 will be described below.
5A, the branching block 20 is set on the electric wire bundle 10 so that the electric wire bundle 10 is fitted into the fitting recess 36 of the first block 31 of the branching block 20 in the unfolded state. At this time, the branching block 20 is set at a predetermined position, such as a bending portion of the electric wire bundle 10.

Then, the second block 32 is pivoted around the pivot axis L by the hinge 50 and folded back relative to the first block 31 (see FIG. 5(b)). By folding the second block 32 back relative to the first block 31 in this manner, the opposing surfaces of the first block 31 and the second block 32 face each other, the fitting recess 36 forms the mounting hole 22, and the mounting groove 23 is formed by the mounting groove configuration portion 35. Therefore, the wire bundle 10 fitted into the fitting recess 36 of the first block 31 is in a state in which it is inserted through the mounting hole 22. In this inserted state, a portion of the longitudinal direction of the wire bundle 10 is exposed to the winding space 70.

In this state, the position of the branching piece 20 in the bundle of electric wires 10 is checked, and if it is misaligned from the specified position, the position is adjusted. Once it is confirmed that the branching piece 20 is in the specified position in the bundle of electric wires 10, the branching piece 20 is fixed with a band 40 so that it does not shift out of position relative to the bundle of electric wires 10.

Specifically, the band 40 extending downward from the branching piece 20 in the folded-back state is wound around the outer periphery of the electric wire bundle 10, part of which in the longitudinal direction is exposed in the winding space 70, and the tip of the band 40 that winds around the winding space 70 is inserted through the communication hole 37 and into the insertion hole 62 of the buckle 61 that communicates with the communication hole 37 to prevent the band 40 from loosening. A tensile force is then applied to the band 40 that has been led out to the back side of the insertion hole 62 (the back side when viewed from the front), and the band 40 is wrapped around the outer periphery of the winding space 70 so as to tighten it, completing the fixation of the branching piece 20 to the electric wire bundle 10. The excess length of the band 40 that extends to the back side of the insertion hole 62 is then cut off.

In this way, the wire bundle 1 with a link can be constructed by fixing the branch link 20 to a predetermined position in the longitudinal direction of the wire bundle 10, but multiple branch links 20 may be fixed to the wire bundle 10 depending on the application of the wire bundle 1 with a link.

For example, a plurality of the wire bundles 1 with the blocks may be bundled together to form a wire harness Y, and may be fixed to a protector 100 to form a wire harness X with a protector.
The wire harness Y has a main wire portion Ya and a plurality of branch wires Yb formed by a plurality of wire bundles 1 with blocks, and the wire harness X with protector is composed of a protector 100 and the wire harness Y. In order to form the wire harness X with protector, appropriate connectors 80 are attached to both ends of the wire bundle 1 with blocks.

Specifically, the wire harness X with protector is composed of a wire harness Y constituted by three wire bundles 1 (1a, 1b, 1c) with links, and a protector 100 having a generally groove-shaped cross section.
Each of the wire bundles 1 with a branch block is formed to an appropriate length, and has a branch block 20 attached and fixed at a predetermined position in the longitudinal direction.

The protector 100 is formed into an inverted U-shape when viewed from the side, with side walls 110 that are elongated rectangular when viewed from the front, located on both the front and rear sides when viewed from the front, and a connecting upper surface 120 that connects the upper ends of a pair of side walls 110.
The side walls 110 are spaced apart in the front-rear direction when viewed from the front at an interval corresponding to the height of the branching piece 20 .

Near the lower end of the side wall 110, a rib 111 is provided which projects toward the other side and extends in the longitudinal direction.
The rib 111 is configured to have a thickness and a protruding amount that allows it to fit into the mounting groove 23 of the branching piece 20.

The protector 100 thus constructed has a pair of side walls 110 that can be opened and closed, and when one side wall 110 is opened relative to the other side wall 110, the wire bundle 1 with the link is attached to form the wire harness Y, and also forms the wire harness with protector X.

The following describes assembly of the protector-equipped wire harness X using three wire bundles 1. For example, a wire bundle 1a having a predetermined length and a branch block 20 is attached to the protector 100.
At this time, one end of the wire bundle with link 1a (upper left side in FIG. 8) is led out from one end of the protector 100 (upper left side in FIG. 8), and a branch link 20 is attached near the other end of the protector 100 (lower right side in FIG. 8), and the end side from the branch link 20 is led out to the open side of the protector 100, which has a groove-shaped cross section, to form a branch wire Yb1.

To assemble the wire bundle 1 with the block to the protector 100 in this manner, as shown in FIG. 8(b), the branch block 20 provided on the wire bundle 1a with the block is attached to the rib 111 on the other side wall 110 of the protector 100 with one side wall 110 open. The rib 111 is the lower end of the side wall 110, and is adjacent to the edge that separates the inside and outside of the protector 100 when the protector 100 is closed.

The branching piece 20 is attached to the rib 111 of the side wall 110 by fitting the rib 111 into one of the two mounting grooves 23 with the mounting groove 23 facing in the opposing direction of the side wall 110 (see the enlarged view of part a in Figure 8 (b)).

A branch block 20 is provided on the wire bundle 1b, which is shorter than the wire bundle 1a, and the other end of the wire bundle 1b (lower right side in FIG. 8) is led out from the other end of the protector 100 (lower right side in FIG. 8). The branch block 20 is attached to one side of the branch wire Yb1 in the protector 100, and the end side of the wire bundle 1b is led out from the branch block 20 to form the branch wire Yb2.

Two branch blocks 20 are provided on the wire bundle 1c, which is shorter than the wire bundle 1b, and the two branch blocks 20 are attached to one side of the branch block 20 of the wire bundle 1b in the protector 100 at a predetermined distance, and the ends of the wire bundle 1c are led out from the branch block 20 to form branch wires Yb3 and Yb4.

In the wire bundles 1a, 1b, and 1c assembled to the protector 100 by attaching the branch blocks 20 as described above, the parts of the wire bundle 1a other than the branch wire Yb1, the parts of the wire bundle 1b other than the branch wire Yb2, and the parts of the wire bundle 1c other than the branch wires Yb3 and Yb4 constitute the main line portion Ya along the longitudinal direction of the protector 100 (the direction connecting the upper left side and the lower right side in FIG. 8). In this way, by assembling the wire bundles 1a, 1b, and 1c, a wire harness Y having the main line portion Ya and the branch wire Yb is constituted, and a wire harness X with a protector can be constituted by the wire harness Y fixed to the protector 100 by the branch blocks 20 in each wire bundle 1.

As described above, the branching blocks 20 of each wire bundle 1 with blocks are attached to the rib 111 of one side wall 110, and the other side wall 110 is closed and the other rib 111 is fitted into the attachment groove 23 of the branching block 20 to sandwich and fix it, thereby forming the wire harness with protector X. In the wire harness with protector X thus configured, the branching block 20 attached to the rib 111 is positioned inside the protector 100 near the edge that separates the outside and inside of the protector 100.

As described above, the branch block 20 attached to the longitudinal middle portion of the wire bundle 10 is provided with a clamping block 30 that clamps the wire bundle 10 and has higher rigidity than the wire bundle 10, a band 40 that wraps around the outer periphery of the wire bundle 10 and tightens the clamping block 30 that clamps the wire bundle 10 in the clamping direction (front-to-back direction when viewed from the front), and a buckle 61 that fixes the band 40 in a state where it is wrapped around the outer periphery of the wire bundle 10, so that the wire harness Y can be manufactured efficiently and with high precision.

In more detail, the clamping block 30, which has higher rigidity than the electric wire bundle 10, clamps the electric wire bundle 10 at a predetermined position in the longitudinal direction, and the clamping block 30, which clamps the electric wire bundle 10, is tightened in the clamping direction (front-rear direction when viewed from the front) with a band 40 that is wrapped around the outer periphery of the electric wire bundle 10 and a buckle 61 that fixes the band 40 in a state where it is wrapped around the outer periphery of the electric wire bundle 10, thereby making it possible to fix the branching piece 20 at a predetermined position of the electric wire bundle 10 with high precision. Therefore, by using the electric wire bundle 10 with the branching piece 20 attached at the bending position, it is not necessary to measure the position each time, and it is possible to efficiently configure the wire harness Y having the branch wire Yb with high precision.

By attaching the branch block 20, which has a higher rigidity than the flexible electric wire bundle 10, to the electric wire bundle 10 of the clamping block 30, a highly rigid portion can be provided in the flexible electric wire bundle 10. Therefore, the branch block 20 of the flexible electric wire bundle 10 can be held by a chuck of the manufacturing device, so that the manufacturing of the wire harness Y can be automated. By providing an identifier to the branch block 20, the type of the wire bundle 1 with the wire harness can be identified, so that the wire bundle 1 with the wire harness can be manufactured more efficiently and automatically by the manufacturing device.

The clamping block 30 is composed of a pair of a first block 31 and a second block 32 that clamp the electric wire bundle 10 from both sides in the cross-sectional direction, and a hinge 50 that connects the pair of the first block 31 and the second block 32 to each other so that they can pivot in the clamping direction (front-rear direction when viewed from the front). Therefore, the pair of the first block 31 and the second block 32 can be integrated by the hinge 50, so that the number of parts can be reduced. Furthermore, the branching block 20 can be attached to the specified position of the electric wire bundle 10 more efficiently than when multiple parts are assembled to clamp the electric wire bundle 10.

In addition, the opposing surfaces of the pair of first block 31 and second block 32 are provided with fitting recesses 36 that penetrate in a direction parallel to the pivot axis L of the hinge 50 and into which the wire bundle 10 fits. Therefore, by fitting the wire bundle 10 into the fitting recesses 36 provided on the opposing surfaces of the first block 31 and second block 32 and pivoting the pair of first block 31 and second block 32 in the clamping direction (front-rear direction when viewed from the front) with the hinge 50, the wire bundle 10 can be clamped between the first block 31 and second block 32 and the branching piece 20 can be attached to the wire bundle 10.

In addition, since the mating recess 36 penetrates the opposing surfaces of the first block 31 and the second block 32 in a direction parallel to the pivot axis L of the hinge 50, the branch block 20 can be accurately attached in a direction perpendicular to the axial direction of the wire bundle 10 fitted into the mating recess 36.

The band 40 and buckle 61 are arranged in the center of the clamping block 30 in the width direction as viewed from the front, and the band 40 extends along the clamping direction (front-rear direction as viewed from the front) and an orthogonal direction perpendicular to the width direction as viewed from the front, and a winding space 70 in which the band 40 winds the wire bundle 10 is formed in the center of the clamping block 30 in the width direction as viewed from the front. Therefore, the wire bundle 10 can be tightened by the band 40 in the winding space 70 provided in the center of the clamping block 30 in the width direction as viewed from the front, and the branch piece 20 can be securely fixed to a predetermined position of the wire bundle 10.

In more detail, the band 40 extends along the clamping direction (front-to-back direction when viewed from the front) and the orthogonal direction perpendicular to the width direction when viewed from the front in the winding space 70 formed in the center of the clamping block 30 in the width direction when viewed from the front, and winds the wire bundle 10. Therefore, the band 40 can be wound around the wire bundle 10 clamped by the clamping block 30 in the cross-sectional direction perpendicular to the longitudinal direction.

In addition, the winding space 70 in which the band 40 winds the wire bundle 10 is formed in the center of the clamping block 30 in the width direction when viewed from the front, so the wire bundle 10 can be fixed more stably than when the band 40 winds and fixes the wire bundle 10 near the end of the clamping block 30 in the width direction when viewed from the front.

In addition, because the branch wire Yb is formed by bending the electric wire near the attachment point where the branching block 20 is attached, the branch wire Yb can be formed with high precision from the electric wire bent near the attachment point of the branching block 20 attached to a predetermined position of the electric wire bundle 10. Therefore, the branch wire Yb can be formed efficiently and with high precision compared to the case where the position to bend the electric wire is measured each time, the electric wire is bent, and the branch wire is fixed with tape to form the branch wire Yb.

In addition, a protector 100 is provided to cover the assembled wire bundle 1 with the blocks, and the branch block 20 is fixed to the protector 100, so that the flexible wire bundle 10 can be fixed in an accurate position relative to the protector 100 by the highly rigid branch block 20. In addition, the branch wire Yb extending from the protector 100 can be accurately bent with the bending point being near the branch block 20 that is accurately attached to a predetermined position.

In addition, the branch piece 20 is located inside the protector 100, in the rib 111 near the bottom end of the side wall 110, which is close to the edge that separates the outside from the inside, so that the branch line Yb can be accurately led out from the protector 100.
