On the contrary; in the protector of the present invention 301 shown in Fig. 7 and 8; being formed on male member part 350 on the top cover 301B inserts respectively in the insertion space 352 on the relative both sides of the center conductor extension 311 that is separately positioned on protector main body 301A; therefore, can prevent mentioning of top cover 310B above-mentioned.In addition, only male member part 350 need be set, and not need to be provided with any additional locking mechanism, therefore, lock operation is not loaded down with trivial details.
Then, will describe the fourth embodiment of the present invention in detail with reference to Figure 12 and 13.
Figure 12 A and 12B illustrate the structure of the protector of this embodiment, and Figure 12 A is the vertical view that the situation of opening of top cover is shown, and Figure 12 B is the enlarged perspective of part shown in the arrow Ib of Figure 12 A.
A plurality of offset extensions 410 are arranged on towards the sidepiece of the Bindle wire protector 401 that leaves hinge 404.U-shaped cross section (darker) the circle wall 410A that forms the major part (bottom) of offset extension 410 respectively is formed on the protector main body 402, and U-shaped cross section (more shallow) the circle wall 410B that forms the remainder (top) of offset extension 410 respectively is formed on the top cover 403.
The main traverse line that the circle wall 410A of the offset extension 410 on the protector main body 402 is connected to the main traverse line part Wa that is formed for holding wire harness W is installed the sidewall sections of the circle wall 402A of path 405.In this case, the circle wall 410A of each offset extension 410 obliquely (when it being regarded as lead path is installed) with the U-shaped bend mode be connected to and form the bottom that main traverse line is installed the circle wall 402A of path 405.Equally, the circle wall 410B of the offset extension 410 on the top cover 403 main traverse line that is connected to the main traverse line part Wa that is formed for holding wire harness W is installed the sidewall sections of the circle wall 403A of path 405.Each offset extension 410 has with main traverse line installs the lead installation path that path 405 is communicated with.Be locked in a time-out in protector main body 402 and top cover 403, the circle wall 3A of top cover 403 and the lower edge of 410B are docked at respectively on the top edge of the circle wall 402A of protector main body 402 and 410A.
Casting die part 420 be respectively formed on the inner surface of sidewall sections of circle wall 402A of protector main body 402 predetermined portions and from its protrusion; and be pressed on lead and install on the Width of path 405 away from this sidewall sections, be installed in main traverse line wire harness (lead) W in the path 405 is installed, separate with this sidewall sections to keep wire harness W.Casting die part 420 is arranged on the lead of offset extension 410 and path is installed from the zone that main traverse line installation path 405 stretches out.More particularly, each casting die part 420 is formed on and forms main traverse line and install on the inner surface of sidewall sections of circle wall 402A of path 405, and is arranged on the inboard corresponding to the sharp bend coupling part 412 of the circle wall 410A of offset extension 410.
This casting die part 420 is to protrude from the inner surface of the sidewall sections of the circle wall 402A of protector main body 402, then along the lead installation direction from upstream side downstream side bend to the form of L shaped springs.That is to say that casting die part 420 comprises: the proximal part 421 of inner surface of sidewall sections that is connected to the circle wall 402A of protector main body 402; The L shaped sweep 422 that stretches out from proximal part 421; And the distal portions 423 that extends near the zone the Width core that is positioned at offset extension 410.Be used to guide the cylinder tube shape of offset or the far-end that columniform offset leader 425 is formed on casting die part 420.The top edge of casting die part 420 is higher than the top edge of sidewall sections of the circle wall 410A of offset leader 410.
Then, operation will be described.When using this Bindle wire protector 401; at first; the main traverse line part Wa of wire harness W is contained in the main traverse line installation path 405 of protector main body 402; and enter offset extension 410 respectively from the offset Wb that main traverse line part Wa tells; then, draw from these offset extensions 410 respectively.
At this moment, each casting die part 420 is arranged on the inboard of sweep (branching into the crooked shape of U), and therefore, this lead (main traverse line part Wa and offset Wb) keeps separating with the sidewall sections of the circle wall 402A that forms lead installation path 405.Therefore; in the lead fitting operation, prevent that lead (main traverse line part Wa and offset Wb) is arranged on the edge of sidewall sections, therefore; when top cover 403 closures, prevent that lead (main traverse line part Wa and offset Wb) from keeping (or mounting board) between protector main body 402 and top cover 403.
Figure 13 A and 13B are the schematic diagrames of the comparative example that illustrates for the advantage that the embodiment of the invention is described.Figure 13 A is corresponding to Figure 12 A, and Figure 13 B is corresponding to Figure 12 B.
The protector 500 of this comparative comprises protector main body 402 and top cover 403, and except casting die part 420 (seeing Figure 12 A and 12B) is not set, is similar to the above embodiment of the present invention.Therefore, identical composed component will be given identical Reference numeral, and its description is removed.
Under the situation of the comparative example that does not have casting die part 420; when offset Wb is bent into U bending shape; offset Wb is from zone that the main traverse line part Wa of wire harness W tells; as in the zone shown in the arrow C; inboard at sweep; this lead very might extend the shortest path (for branch), and it may be arranged on the edge of sidewall sections of the circle wall 402A of protector main body 402 and 410A very much.In this case, when closing top cover 403, this lead of possible clip.
On the contrary, in an embodiment of the present invention, utilize the effect of casting die part 420, can make this lead (main traverse line part Wa and offset Wb) keep separating with the sidewall sections (form lead path 405 is installed) of sidewall sections 402A.Therefore, prevent that lead is arranged on the sidewall sections, and when top cover 403 is closed, prevent that effectively this lead is by clip.Particularly when offset Wb is installed in than low position, the position of main traverse line part Wa, this offset is set on the sidewall sections edge on this stub area easily.Yet, utilize the effect of casting die part 420, can prevent this situation, and prevent this lead of clip, thereby strengthen operating efficiency.
In this case, the top edge of casting die part 420 is higher than the top edge of the circle wall 410A of offset extension 410, shown in Figure 12 B, therefore, prevents that reliably lead is set on the edge of sidewall sections.In addition, casting die part 420 is forms of springs spare, and therefore, flexibly the clamping lead separates with sidewall sections.In addition, even at lead during by abrupt bend, because its elastic pressure parts part 420 also can this lead of smooth guide.
In addition, cylinder tube shape or columniform offset leader 425 are formed on the far-end of casting die part 420, therefore, be increased with the contact area of lead, so the power that lead is applied be reduced, thereby reduce damage to lead.
In order to prevent that lead is arranged on the edge of sidewall sections, utilize the adhesive tape T shown in Figure 13 A and 13B usually, to applying the adhesive tape winding operation with these parts of the lead of the adjacent setting of component respectively.In the present invention, casting die part 420 prevents that lead is arranged on the edge of sidewall sections, therefore, especially needn't carry out the adhesive tape winding operation, saves required time and the work of adhesive tape winding operation, omits the winding adhesive tape and helps to save natural resources.In addition, do not use the winding adhesive tape, therefore the wire harness that can break easily, can improve the partition ability.
For example, in the above-described embodiments, casting die partly is arranged on the inboard place of sweep of the offset extension 410 of U-shaped bending.Yet this casting die part also can be arranged on the inboard of the abrupt bend part of the simple shape outside this component.In this case, can solve, when under the abrupt bend condition lead being installed, lead usually extends shortest path in the inboard of sweep, and is set at the problem at the edge of sidewall sections.Therefore, when closing top cover, prevent that lead is by clip.
The present invention is not limited to the foregoing description, and can suitably carry out various modifications, improvement etc.In addition, as long as can realize the present invention, the material of each component units of the foregoing description, shape, size, quantity, be provided with etc. all is random, and unrestricted.
