Technical Field

[0001] The present invention relates to the technical field of wire fixers, and in particular to a wire fixer for a wire harness. Background Art

[0002] In the modern electronic and electrical field, wiring harnesses, as an important electrical connection component, are widely used in various devices and systems, carrying out key tasks such as transmitting power and signals. They are typically composed of multiple wires and terminals connected to the wires at both ends. The terminals at each end of the wiring harness are plugged into the holes of two connectors, thus achieving electrical connections between different components or systems and ensuring the normal operation of the equipment.

[0003] However, in the actual application and production of wire harnesses, due to the lack of effective restraint and fixation measures in the wire harnesses themselves, they will naturally sag or bend due to gravity. These factors will cause the wire harnesses to deviate from the intended installation position, making the connection status between the terminals and connectors unstable. Summary of the Invention

DETAILED DESCRIPTION

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. 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 depart from the spirit and scope of the present invention.

[0019] As mentioned in the background, it's necessary to constrain the position of the wiring harness while ensuring its stability. Existing technology uses slots in power strips to accommodate the wiring harness. However, the cross-sectional dimensions of the wiring harness don't match the width of the slot well, making it prone to wiggling within the slot and even detaching from the slot's notch, severely impacting the stability of the harness's fixation.

[0020] In view of this, please refer to Figure 1 The wire fixer provided in the embodiment of the present invention can solve this problem, which will be described in detail below.

[0021] An embodiment of the present invention provides a wire fixer, comprising: The rotating member 100 has a rotating hole 100a formed thereon, the rotating hole 100a connecting the interior and exterior of the rotating member 100 so as to allow the wiring harness to pass through the rotating hole 100a and enter the interior of the rotating member 100; The transmission member 200 is in transmission connection with the rotating member 100, and the transmission member 200 drives the rotating member 100 to rotate around its own axis; The pull rope 300 has a fixed end 300a and a movable end 300b. The fixed end 300a is fixed, and the movable end 300b is connected to the rotating member 100. The movable end 300b rotates with the rotating member 100 so that the pull rope 300 can wrap around and fix the wiring harness entering the interior of the rotating member 100.

[0022] The wire harness enters the interior of the rotating member 100 through the rotating hole 100a, and the rotating member 100 is driven to rotate around its own axis by the transmission member 200. The movable end 300b of the pull rope 300 rotates with the rotating member 100, so that the pull rope 300 is wound around the wire harness. By wrapping the drawstring 300, the wiring harness is effectively constrained, preventing it from swaying or becoming detached. Compared to traditional extension strip fastening methods, this drawstring-wrapped fastening method is more adaptable to wiring harnesses of varying sizes, provides a more secure fixation, and significantly improves the stability and reliability of the wiring harness.

[0023] like Figure 1 and Figure 3 As shown, the wire fixer also includes: The housing 400 includes two housing side panels 410. The rotating member 100 and the gear set 210 of the transmission member 200 are arranged between the two housing side panels 410. The protection of the housing side panels 410 ensures that the rotating member 100, the gear set 210 and other components can operate normally and the transmission relationship between them is stable and reliable.

[0024] refer to Figure 1 The housing 400 further includes two supports 420 , which are used to support the two housing side panels 410 , etc. The supports 420 include a support horizontal plate 421 and a support vertical plate 422 .

[0025] The support vertical plate 422 is connected between the two housing side plates 410 to maintain a gap between the two housing side plates 410 for arranging the rotating member 100, the gear set 210, etc.

[0026] The support plate 421 is located below the two housing side panels 410 and has mounting holes 421a formed therein. During installation, fasteners such as bolts are passed through the mounting holes 421a to secure the cable holder securely in place, ensuring stability and reliability during use. Alternatively, the cable holder can be secured in place using magnetic means, suction cups, or other similar methods.

[0027] Continue to refer Figure 1 The distance between the two housing side panels 410 defines the thickness of the housing 400. The two support brackets 420 are located on the left and right sides of the width direction of the housing 400, which enhances the overall structural strength of the housing 400 and prevents the housing from shaking when subjected to external forces.

[0028] The support cross plate 421 of each support 420 extends on both sides of the thickness direction of the shell 400. The contact area between the support cross plate 421 and the installation position is increased by the extension of the support cross plate 421. At the same time, the installation hole 421a can be opened in the extended part of the support cross plate 421, that is, the number of the installation holes 421a is increased, further enhancing the connection strength between the wire holder and the installation position, ensuring that the wire holder can remain stable during long-term use.

[0029] Taking the two mounting holes 421 a provided on each support horizontal plate 421 as an example, the two mounting holes 421 a are located on both sides of the shell 400 in the thickness direction.

[0030] like Figure 1 and Figure 3 As shown, the housing 400 further includes a support block 430, which is connected between the two housing side plates 410. The support block 430 is located above the support base 420, so that the housing 400 forms a more stable support system, ensuring that the rotating member 100, gear set 210 and other components installed thereon can operate normally.

[0031] like Figure 1 and Figure 3 As shown, the housing 400 further includes a guide wheel 700, which is arranged in a manner to rotate about its own axis within the housing 400. Specifically, a fixed shaft is connected between the two housing side plates 410, and the guide wheel 700 is sleeved on the fixed shaft and located between the two housing side plates 410 to enable the guide wheel 700 to rotate about its own axis.

[0032] There are multiple guide wheels 700, which are spaced apart along the circumference of the rotating member 100. The multiple guide wheels 700 can fit in contact with the outer edge of the rotating member 100. In this embodiment, the number of guide wheels 700 is four, but not limited to this. This layout allows the multiple guide wheels 700 to support and guide the rotating member 100 from different directions, ensuring that the rotating member 100 is evenly stressed during rotation, avoiding shaking or deviation, and thus ensuring that the rotating member 100 can stably rotate around its own axis.

[0033] It should be noted that the angle between the line connecting the center of the two adjacent guide wheels 700 and the rotating member 100 is greater than the opening angle of the rotating through hole 100a.

[0034] Taking the center of the rotating member 100 as the center point, connect the circles of two adjacent guide wheels 700 respectively, and the angle between the two connecting lines formed in this way should be greater than the opening angle of the rotating through hole 100a. During the rotation of the rotating member 100, if the above-mentioned angle relationship is not satisfied, it is easy for the rotating member 100 to rotate unsteadily. For example, when the rotating member 100 rotates to a certain position, the two adjacent rotating members 100 are opposite to the rotating through hole 100a and do not fit in with the outer edge of the rotating member 100, that is, the guidance of the rotating member 100 fails, which causes the rotating member 100 to rotate unstably. Reference Figure 1 , the guide wheel 700 includes: Two wheel side plates 710; A wheel body 720, wherein the wheel body 720 is connected between the two wheel side plates 710; The diameter of the wheel body 720 is smaller than the diameter between the wheel side plates 710 . The outer edge of the rotating member 100 is located between the two wheel side plates 710 and fits in with the outer edge of the wheel body 720 .

[0035] The outer edge of the rotating member 100 is confined between the two wheel side plates 710, preventing the rotating member 100 from axial displacement during rotation, further ensuring the rotational stability of the rotating member 100. The outer edge of the wheel body 720 fits closely to the outer edge of the rotating member 100 to provide a good guiding effect.

[0036] like Figure 1 、 Figure 3 and Figure 4 As shown, the rotating member 100 includes: Two rotating side plates 110 are arranged along the thickness direction of the rotating member 100 , and the rotating through hole 100 a penetrates the two rotating side plates 110 along the thickness direction of the rotating member 100 .

[0037] The inner edges of the two rotating side plates 110 together enclose the interior of the rotating member 100 , which provides space for winding and fixing the wire harness. The outer edges of the two rotating side plates 110 together constitute the outer edge of the rotating member 100 .

[0038] The rotation through hole 100a passes through the two rotation side plates 110 along the thickness direction of the rotating member 100 and connects the inside and outside of the rotating member 100, so that the wiring harness outside the rotating member 100 can slide into the inside of the rotating member 100 through the rotation through hole 100a.

[0039] As can be seen, the rotating side plate 110 is arc-shaped, and its curvature determines the opening angle of the rotating hole 100a. The sum of the two curvatures is 360 degrees. The width of the rotating hole 100a is greater than the diameter of the cross section of the wiring harness. In this embodiment, the opening angle of the rotating hole 100a is 30 degrees to 45 degrees.

[0040] like Figure 1 and Figure 3 As shown, when the rotating member 100 is arranged on the housing 400 , the two rotating side plates 110 are positioned between the two wheel side plates 710 of the guide wheel 700 .

[0041] The interior of the rotating member 100 is exposed on both sides of the housing 400, specifically through side holes 411 formed in each housing side plate 410. The diameter of the side holes 411 is larger than the diameter of the circle formed by the inner edges of the rotating member 100, and smaller than the diameter of the circle formed by the outer edges of the rotating member 100.

[0042] The above design ensures that the interior of the rotating member 100 is completely exposed outside the housing side plate 410, facilitating smooth entry of the wiring harness into the rotating member 100. It also prevents the rotating member 100 from falling off the housing side plate 410, ensuring the stability of the assembly of the rotating member 100 and the housing 400.

[0043] The shell 400 is provided with a shell through hole 400a, which passes through the two shell side plates 410 along the thickness direction of the shell 400. The shell through hole 400a is relatively connected to the rotation through hole 100a, so that the wiring harness passes through the shell through hole 400a and the rotation through hole 100a in sequence and enters the interior of the rotating part 100.

[0044] like Figure 3 and Figure 4 As shown, the rotating member 100 further includes: The ring gear 120 is connected between the two rotating side plates 110 .

[0045] The design of the ring gear 120 not only enhances the structural strength of the rotating member 100 , but also provides a basis for the meshing transmission of the transmission member 200 .

[0046] The rotating through hole 100a also passes through the ring gear 120 along the thickness direction of the rotating member 100. This design ensures the continuity of the rotating through hole 100a on the entire rotating member 100, so that the wiring harness can smoothly pass through the rotating through hole 100a into the interior of the rotating member 100 without affecting the meshing transmission between the ring gear 120 and the gear set 210.

[0047] refer to Figure 3 , the transmission member 200 includes: a gear set 210 , wherein the gear set 210 is meshed with the ring gear 120 ; The power 220 is in transmission connection with the gear set 210 .

[0048] The gear set 210 is located between the two shell side plates 410 , and the power 220 can be a motor, which can be fixed on the outside of one of the shell side plates 410 . The output shaft of the power 220 passes through the shell side plate 410 and is in transmission connection with the gear set 210 .

[0049] Continue to refer Figure 3 The gear set 210 includes a driving wheel 211 and two driven wheels 212. The driving wheel 211 is connected to the output shaft of the power 220. The driven wheels 212 are rotatably disposed between the two housing side plates 410. The two driven wheels 212 are disposed on the left and right sides of the driving wheel 211, and each driven wheel 212 meshes with the driving wheel 211 and the driven ring gear 120. This layout makes the gear set 210 more compact and can better balance the forces during the transmission process, thereby driving the stable rotation of the rotating member 100.

[0050] The teeth of the gear ring 120 are arranged outward, and the outer edge of the driven wheel 212 is located between the two rotating side plates 110 and meshes with the teeth of the gear ring 120 facing outward.

[0051] When the power 220 is started, it drives the driving wheel 211 to rotate, and the driving wheel 211 drives the two driven wheels 212 to rotate. The driven wheels 212 are engaged with the ring gear 120, thereby driving the rotating member 100 to rotate.

[0052] like Figure 1 and Figure 3 As shown, the wire fixer also includes: An opening and closing member 610 rotatably disposed between the two rotating side plates 110 , and configured to open and close the rotating through hole 100 a ; The tension spring 620 is located between the two rotating side plates 110 , one end of the tension spring 620 is connected to the ring gear 120 , and the other end of the tension spring 620 is connected to the opening and closing member 610 .

[0053] There can be two opening and closing members 610, which are respectively arranged on the left and right sides of the rotating through hole 100a. That is, the wiring harness can pass between the two opening and closing members 610, which not only ensures the convenience of introducing the wiring harness, but also prevents the wiring harness from accidentally falling out in the closed state.

[0054] The inner wall of the gear ring 120 is provided with a receiving groove 121, and the tension spring 620 is hidden in the receiving groove 121 to prevent the tension spring 620 from protruding into the interior of the rotating member 100 and interfering with the winding operation of the wire harness by the pull rope 300. The working process of the opening and closing member 610 is as follows: Under the action of the tension of the tension spring 620, the opening and closing member 610 closes the rotating through hole 100a.

[0055] When the wiring harness needs to be introduced, the wiring harness pushes the opening and closing member 610 under the action of external force, so that the opening and closing member 610 compresses the tension spring 620 to open the rotating through hole 100a, and the wiring harness can enter the interior of the rotating member 100 through the opened rotating through hole 100a.

[0056] After the wiring harness enters the interior of the rotating member 100 , the external force disappears, and the opening and closing member 610 recloses the rotating through hole 100 a under the restoring force of the tension spring 620 .

[0057] like Figure 1 and Figure 2 As shown, the fixed end 300a and the movable end 300b of the pull rope 300 are located on the same side of the rotating member 100. The same-side layout of the fixed end 300a and the movable end 300b of the pull rope 300 facilitates the coordinated operation between the pull rope 300 and the rotating member 100, and facilitates the winding of the pull rope 300 on the wire harness.

[0058] The distance between the movable end 300b and the rotating member 100 is shorter than the distance between the fixed end 300a and the rotating member 100. This distance difference is a key factor in the pull cord 300's winding function. This provides the space necessary for the movable end 300b to circumvent the rotating member 100. Specifically, when the rotating member 100 drives the movable end 300b to rotate, the movable end 300b can circumvent the pull cord 300 at the fixed end 300a, allowing the pull cord 300 to wind around the wiring harness entering the rotating member 100.

[0059] like Figure 1 and Figure 2 As shown, a first pull rope column 510 is provided on the housing 400, a second pull rope column 520 is provided on the rotating member 100, the fixed end 300a of the pull rope 300 is connected to the first pull rope column 510, and the movable end 300b of the pull rope 300 is connected to the second pull rope column 520.

[0060] The first rope-pulling column 510 and the second rope-pulling column 520 may respectively define a slot 530 , and the rope 300 may be hooked in the slot 530 .

[0061] The pull rope 300 may be annular, with its fixed end 300a wrapped around the first pull rope post 510 and embedded in the slot 530, and the movable end 300b wrapped around the second pull rope post 520 and embedded in the slot 530. This improves the stability of the pull rope 300 fixed to the first pull rope post 510 and the second pull rope post 520, ensuring the normal winding of the pull rope 300.

[0062] The operation method of the wire fixer is as follows: Step 1: Preliminary positioning of the wiring harness 1000 refer to Figure 5 The wire harness 1000 is grabbed by a manipulator or manually, and passed through the housing through-hole 400a and the rotating through-hole 100a in sequence, and then enters the interior of the rotating member 100. At this time, the two ends of the wire harness 1000 pass through the two sides of the interior of the rotating member 100 respectively.

[0063] The distance between the wire harness 1000 and the pull rope 300 is adjusted so that the wire harness 1000 moves to a position close to the pull rope 300 to achieve preliminary positioning of the wire harness 1000 and prepare for the subsequent winding and fixing of the wire harness 1000 by the pull rope 300.

[0064] The pull rope is initially arranged in a straight line, wherein the fixed end 300a and the movable end 300b of the pull rope 300 are respectively arranged on both sides of the rotation hole 100a, and the wiring harness 1000 is located between the pull rope 300 and the rotation hole 100a.

[0065] Step 2: The drawstring 300 is wrapped around the harness 1000 and fixed. 1. The transmission member 200 drives the rotating member 100 to rotate 90° counterclockwise refer to Figure 6 The fixed end 300a of the pull cord 300 is fixed to the housing 400 and remains in place. The movable end 300b is connected to the rotating member 100 and rotates 90° counterclockwise. During the rotation, the pull cord 300 gradually changes from a straight line to an L-shaped arrangement. At this point, the wiring harness 1000 is located at the corner of the L-shaped pull cord 300.

[0066] The rotating through hole 100 a also rotates 90° counterclockwise along with the rotating member 100 . At this time, the rotating through hole 100 a and the housing through hole 400 a are staggered.

[0067] 2. The transmission member 200 drives the rotating member 100 to rotate 270° counterclockwise refer to Figure 7 The movable end 300 b rotates 270° counterclockwise along with the rotating member 100 . During the rotation, the pull rope 300 is gradually wound around the wiring harness 100 .

[0068] The pull cord 300 is spirally wound around the surface of the wiring harness 1000. Each time the pull cord 300 rotates a certain angle, it wraps one more turn around the wiring harness 1000. After rotating 270 degrees, the pull cord 300 forms a 270-degree wrap around the wiring harness 1000, exerting a certain restraining force on the wiring harness 1000.

[0069] 3. The transmission member 200 drives the rotating member 100 to rotate 360° counterclockwise refer to Figure 8 The movable end 300b rotates 360° counterclockwise along with the rotating member 100. During the rotation, the pull rope 300 is continuously wound around the wire harness 1000, and finally completes the 360° winding.

[0070] In step 2, the transmission member 200 drives the rotating member 100 to rotate counterclockwise 360°, causing the pull cord 300 to wrap around the wiring harness 1000 360°. This 360° wrapping allows the pull cord 300 to completely enclose the wiring harness 1000, forming a relatively tight restraint structure. This restraint effectively prevents the wiring harness 1000 from shaking or shifting during subsequent use, ensuring the stability and reliability of the wiring harness 1000.

[0071] After the pull rope 300 wraps the wire harness 1000 360°, the robot arm can release the wire harness 1000 .

[0072] In summary, the rope winding method can better adapt to different sizes of wire harnesses, and the fixing effect is more solid, greatly improving the stability and reliability of the wire harness fixation. At the same time, the robot and the transmission member 200 cooperate to achieve automated wire fixation and improve efficiency.

Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. The scope of the patent application of the present invention cannot be limited by these embodiments alone. That is, any equivalent changes or modifications made according to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
