Description

Technical Field

[0001] The invention relates to the technical field of wire harness installation equipment, and in particular to a wire harness protection structure for fixing a wire harness. Background Art

[0002] The wiring harness refers to the overall device that provides service for the load source, which includes metal wires and rubber that wraps the metal wires. In order to prevent the wiring harness from being affected by the external environment, the wiring harness is generally fixed and protected by a wiring harness protection structure.

[0003] These wire harness protection structures are usually injection molded products formed by injection molding. Injection molded products usually have a wire trough structure, and when the wire harness is matched with the corresponding wire harness protection structure, it is usually fixed by interference fit between the ribs set on the inner wall of the wire trough and the rubber of the wire harness. In addition, in order to prevent the two ends of the wire harness from being unable to be installed in the specified interface, a certain margin will be left in the length of the wire harness.

[0004] However, during the actual use of the wiring harness, there are generally more vibrations or oscillations, which cause the wiring harness to move within the wiring harness protection structure, resulting in changes in the outer diameter of the wiring harness (i.e., the outer diameter of the rubber on the outer layer of the wiring harness). The restraint of the wiring harness by the wiring harness protection structure becomes ineffective, causing the wiring harness to easily slip out of the wire trough structure.

[0005] The key to such a technical problem is that if the wire harness is to be fixed on the wire harness protection structure, the notch of the wire trough cannot be too small, and is often slightly smaller than the cross-sectional diameter of the wire harness, so that when the wire harness is subsequently installed, the wire harness can be pressed into the wire trough by a certain amount of pressure. However, the notch of the wire trough cannot be too small, otherwise, it is difficult for the subsequent wire harness to be loaded into the wire trough from the notch. However, the notch of the wire trough cannot be too large, otherwise, the subsequent wire harness will easily move out of the notch when it moves. Summary of the invention

[0006] The main purpose of the present invention is to provide a wire harness protection structure, which forms a wire loading port by the cooperation of a blocking portion and a fixing portion, and prevents the wire harness in the installation groove from slipping out of the wire loading port by a second limiting portion.

[0007] Another object of the present invention is to provide a wire harness protection structure, which can fix one wire harness or multiple wire harnesses at the same time by setting the distance between the bottom of the installation groove and the blocking portion, thereby effectively expanding the application scope of the wire harness protection structure.

[0011] Another object of the present invention is to provide a wire harness protection structure, which can effectively enhance the limiting strength of the wire harness protection structure in the opening direction of the installation groove while providing an installation gap for the wire harness by setting the blocking portion as a trapezoidal structure.

The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0033] Those skilled in the art should understand that, in the disclosure of the specification, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0034] In conjunction with the instruction manual Figures 1 to 5 A wire harness protection structure according to a preferred embodiment of the present invention will be described in detail below, wherein the wire harness protection structure is used to fix the wire harness 90.

[0035] The wire harness protection structure has a fixing portion 10, wherein the fixing portion 10 has a first end portion 101 and a second end portion 102 opposite to each other, wherein the fixing portion 10 forms a mounting groove 103 between the first end portion 101 and the second end portion 102 to accommodate the wire harness 90 to be fixed, wherein the mounting groove 103 can be set as a straight groove or a curved groove, wherein when the mounting groove 103 is set as a curved groove, it can play a certain limiting role through the direction of the mounting groove 103, so that the wire harness 90 is not easy to slip out of the mounting groove 103. The fixing portion 10 further has a first groove wall 1031 and a second groove wall 1032 forming the mounting groove 103.

[0036] Preferably, the height of the first groove wall 1031 is the same as the height of the second groove wall 1032. In another embodiment, the height of the first groove wall 1031 is different from the height of the second groove wall 1032.

[0037] The wiring harness protection structure also includes at least two first limiting portions 20 arranged at intervals, wherein each of the first limiting portions 20 extends from the top of the first groove wall 1031 to a predetermined height, and then at least partially bends toward the groove of the installation groove 103 to form a blocking portion 201 at the groove of the installation groove 103, and a wire loading port 202 is formed between the end of the blocking portion 201 and the top of the second groove wall 1032, wherein the size of the wire loading port 202 is larger than the cross-sectional diameter of the wiring harness 90, so that the wiring harness 90 can be subsequently loaded into the installation groove 103 from the wire loading port 202.

[0038] The wire harness protection structure also includes at least one second limiting portion 30 disposed at the top of the second groove wall 1032 and between two adjacent first limiting portions 20 to prevent the wire harness 90 loaded into the installation groove 103 from slipping out of the wire loading port 202 .

[0039] Preferably, a limiting opening 301 is formed between one side of the end of the second limiting portion 30 and one side of the end of the blocking portion 201 close to the second limiting portion 30, and the size of the limiting opening 301 is smaller than the cross-sectional diameter of the wiring harness 90 to prevent the wiring harness 90 loaded into the installation groove 103 from slipping out of the wiring opening 202.

[0040] In this way, when assembling the wiring harness 90, the wiring harness 90 needs to be placed in the wiring port 202 and the limiting port 301 in turn, and the wiring harness 90 needs to be squeezed into the installation groove 103 from the limiting port 301. After being squeezed into the installation groove 103, the wiring harness 90 is restricted by the second limiting portion 30, thereby effectively preventing the wiring harness loaded into the installation groove 103 from slipping out of the installation groove 103.

[0041] Preferably, the first limiting portion 20, the second limiting portion 30 and the fixing portion 10 are integrally formed by an injection molding process, which can effectively save processing time and ensure molding quality. Obviously, based on certain needs, such as when a large number of the wiring harnesses 90 need to be fixed in the mounting groove 103 at the same time, the first limiting portion 20 can also be detachably installed on the top of the groove wall of the mounting groove 103. In addition, the plurality of first limiting portions 20 are preferably evenly distributed along the length direction of the mounting groove 103 to provide uniform restraint force on the wiring harness 90 in the lateral direction.

[0042] It should be noted that in order to enhance the stability of the wiring harness 90 in the installation groove 103, in a preferred embodiment, the groove width of the installation groove 103 is matched with the outer diameter of the wiring harness 90, so as to limit the wiring harness 90 in the width direction, and the distance between the groove bottom of the installation groove 103 and the blocking portion 201 is a multiple of the outer diameter of the wiring harness 90, so that one wiring harness 90 can be fixed in the depth direction of the installation groove 103 through the installation groove 103, or multiple wiring harnesses 90 can be fixed at the same time, which can effectively broaden the scope of application of the wiring harness protection structure.

[0043] It is worth mentioning that when a plurality of the wire harnesses 90 are fixed simultaneously through the installation slot 103, in order to enable the wire harnesses 90 to be inserted into the installation slot 103 more quickly, the slot width of the installation slot 103 is matched with the outer diameter clearance of the wire harness 90. At the same time, the fixing portion 10 is provided with a fixing rib 1033 on the inner wall of the first slot wall 1031 and / or the second slot wall 1032, so that the fixing rib 1033 and the outer diameter of the wire harness 90 are interference-fitted, so that the wire harness 90 can be limited by the fixing rib 1033 while effectively reducing the insertion resistance of the wire harness 90, and the movement of the wire harness 90 in the width direction of the installation slot 103 can be limited or even avoided. The fixing rib 1033 is preferably implemented as an arc-shaped protrusion extending along the opening direction of the installation slot 103 to further reduce the insertion resistance of the wire harness 90.

[0044] In addition, if the fixing ribs 1033 on both sides are arranged opposite to each other in the installation groove 103, when the wire harness 90 is limited by the fixing ribs 1033, there will be a large gap between the wire harness 90 and the inner wall of the installation groove 103, which makes the stability of the wire harness 90 in the installation groove 103 worse. Therefore, it is further preferred that the fixing ribs 1033 are simultaneously arranged on the inner walls of the first groove wall 1031 and the second groove wall 1032, and the fixing ribs 1033 arranged on the first groove wall 1031 and the second groove wall 1032 are staggered along the length direction of the installation groove 103, thereby providing uniform limiting on both sides where the wire harness 90 contacts the installation groove 103, and can effectively reduce the gap between the wire harness 90 and the inner wall of the installation groove 103, so that the wire harness 90 can be more stable during use.

[0045] As a preferred embodiment of the present invention, the second limiting portion 30 is at least partially bent toward the slot of the installation slot 103 to form a second blocking portion 302 at the slot of the installation slot 103, thereby further enhancing the restraining force of the slot of the installation slot 103 on the wiring harness 90.

[0046] Further preferably, a second wire loading opening 303 is formed between the second blocking portion 302 and the top of the opposite first groove wall 1031, wherein the size of the second wire loading opening 303 is larger than the cross-sectional diameter of the wiring harness 90, and a second limiting opening 203 is formed at the nearest position between the end of the first limiting portion 20 and the end of the second blocking portion 302, wherein the size of the second limiting opening 203 is smaller than the cross-sectional diameter of the wiring harness 90, thereby preventing the wiring harness 90 loaded into the mounting groove 103 from slipping out of the second wire loading opening 303.

[0047] Further preferably, there are multiple second limiting portions 30, which are symmetrically and staggeredly matched with multiple first limiting portions 20, and the blocking portion 201 and the second blocking portion 302 are also symmetrically and staggeredly distributed, thereby providing uniform restraining force to the wiring harness 90 in the slot direction of the installation slot 103 and on both sides of the slot, facilitating the installation of the wiring harness 90 and facilitating the one-piece molding of the wiring harness protection structure.

[0048] Thus, the wire harness protection structure allows the wire harness 90 to be inserted into the installation slot 103 through the wire loading port 202, the second wire loading port 303, the limiting port 301 and the second limiting port 203, and then constrains the wire harness 90 on both sides of the opening direction of the installation slot 103 through the first limiting portion 20 and the second limiting portion 30 that are staggered and symmetrically distributed, and also constrains the wire harness 90 in the opening direction of the installation slot 103 through the blocking portion 201 and the second blocking portion 302 that are staggered and distributed in sequence along the length direction of the installation slot 103. The wire harness protection structure not only facilitates the installation of the wire harness 90, but also can effectively fix the wire harness 90 in the installation slot 103. As long as the wire harness 90 does not experience bidirectional repeated force (which is basically impossible), even if the wire harness 90 has problems such as changes in outer diameter during use, it will not slip out of the installation slot 103.

[0049] In a possible embodiment, the corners of the ends of the first limiting portion 20, the second limiting portion 30, the blocking portion 201 and the second blocking portion 302 are all provided with a smooth arc surface structure 304, so as to further protect the wiring harness 90 and prevent the wiring harness 90 from being damaged during the process of inserting the wiring harness 90 into the installation groove 103.

[0050] Further preferably, the fixing portion 10 is provided with through holes 104 corresponding to the blocking portion 201 and the second blocking portion 302 at the bottom of the mounting groove 103, wherein the size of the through hole 104 is preferably larger than the size of the corresponding blocking portion 201 and the second blocking portion 302, thereby facilitating the molding and manufacturing of the blocking portion 201 and the second blocking portion 302 during the stamping process.

[0051] The bottom surfaces of the blocking portion 201 and the second blocking portion 302 close to the mounting groove 103 are respectively provided with recessed portions 305 , wherein the recessed portions 305 extend along the length direction of the mounting groove 103 and cooperate with the wiring harness 90 .

[0052] In some cases where the wiring harness 90 undergoes relative displacement in the mounting groove 103, the wiring harness 90 can be effectively constrained at the bottom surface of the blocking portion 201 through the recessed portion 305. In particular, when the mounting groove 103 simultaneously accommodates two or more of the wiring harnesses 90, the wiring harness 90 close to the blocking portion 201 and / or the second blocking portion 302 will be directly adhered to the recessed portion 305, thereby limiting the movement of the wiring harness 90 along the bottom surface of the blocking portion 201 and / or the second blocking portion 302 toward both sides of the recessed portion 305, i.e., toward the direction of the first limiting portion 20 and the second limiting portion 30.

[0053] As a preferred embodiment of the present application, the blocking portion 201 and the second blocking portion 302 are both configured as a trapezoidal structure, wherein the width dimension of the free end 2011 of the blocking portion 201 is smaller than the width dimension of the fixed end 2012 of the blocking portion 201, wherein the free end 2011 is an end of the blocking portion 201 away from the fixed portion 10, and the fixed end 2012 is an end of the blocking portion 201 close to the fixed portion 10. Since the width dimension of the free end 2011 of the blocking portion 201 is smaller, the wire harness 90 can be inserted more conveniently through the wire loading port 202, the second wire loading port 303, the limiting port 301 and the second limiting port 203; while the width dimension of the fixed end 2012 of the blocking portion 201 is larger, has a higher structural strength, and can increase the contact area between the blocking portion 201 and the wire harness 90, so that the blocking portion 201 can better constrain the wire harness 90 in the opening direction of the mounting slot 103.

[0054] It should be noted that the terms "first, second" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0055] It should be understood by those skilled in the art that the embodiments of the present invention described above are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
