Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to an automotive wiring harness fastener. Background Technology

[0002] In automobile manufacturing, in order to ensure that the wiring harness inside the car can be better arranged according to the predetermined wiring route, wiring harness clips are usually installed on the wiring harness and the clips are correspondingly engaged in the clip holes provided on the car body sheet metal parts to constrain the wiring harness; or a wiring harness retainer is installed on the car sheet metal parts, and then the wiring harness is fixed to the wiring harness retainer with cable ties. The wiring harness retainer usually includes a long strip structure fixing plate with fixing clips on the fixing plate.

[0003] For example, patent publication number CN221767490U discloses an automotive wiring harness fastener, including a first elastic part, a second elastic part, a third elastic part, a first connecting plate, a second connecting plate, and a buckle. The bottom end of the first elastic part is fixed to the top end of the first connecting plate. The second and third elastic parts are symmetrically rotated and installed at both ends of the first elastic part. The first, second, and third elastic parts are combined to form a circular wire harness. The inner wall of the circular wire harness is fixed with several elastic clamping heads arranged around its axis. A cable clamping port for clamping cables is provided between adjacent elastic clamping heads. A first fixing ear is fixed to one end of the second elastic part, and a second fixing ear is fixed to one end of the third elastic part. The first and second fixing ears are connected by a locking screw. A rotating shaft is fixed to the bottom end of the first connecting plate, and a second connecting plate is installed at the other end of the rotating shaft. A buckle is fixed to the bottom end of the second connecting plate. This new type of device is convenient for storing multiple wire harnesses, easy to assemble and disassemble, and not easy to fall off.

[0004] In the aforementioned patent, the inventor believes that although it facilitates the storage and disassembly of multiple wire harnesses during use, the use of elastic elements to secure the wire harnesses alone is insufficient in terms of stability. When the vehicle is subjected to vibration and bumps, the wire harnesses are prone to coming loose.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model discloses an automotive wiring harness fastener, which forms a circular wiring harness ring frame by setting a first fixing ring plate and a second fixing ring plate, so that multiple automotive wiring harnesses can be concentrated and fixed inside the wiring harness ring frame. In conjunction with a first support rod and a second support rod set on one side of the wiring harness ring frame, both of which are semi-circular in structure and adapted to the shape of the wiring harness ring frame, the support rods can limit and support the wiring harnesses clamped on the elastic buckles.

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See also Figures 1-6 This utility model provides an automotive wiring harness fastener, including a first fixing ring plate 1 and a second fixing ring plate 2. The first fixing ring plate 1 is rotatably connected to the second fixing ring plate 2 via a hinge, and the first fixing ring plate 1 and the second fixing ring plate 2 form a circular wiring harness ring frame.

[0030] The wire harness ring frame formed by fixing ring plate 1 and fixing ring plate 2 can facilitate the centralized fixing of multiple automotive wire harnesses on the inner side of the wire harness ring frame.

[0031] In this embodiment, a mounting base 13 is fixedly connected to the bottom of the fixed ring plate 2.

[0032] Mounting base 13 is provided with mounting holes, the positions of which can be used with fasteners to fix the entire automotive wiring harness fastener to the position of the automotive wiring harness.

[0033] In this embodiment, several elastic buckles 3 are fixedly connected to the inner walls of both the first fixed ring plate 1 and the second fixed ring plate 2. Two adjacent elastic buckles 3 are used to clamp the automotive wiring harness.

[0034] The elastic buckle 3 is made of elastic plastic, and both sides of the elastic buckle 3 are provided with wire grooves for clamping the automotive wiring harness.

[0035] In this embodiment: a support rod 4 is rotatably connected to one side of the fixed ring plate 1, and a connecting rod 41 is fixedly connected to one end of the support rod 4. A support rod 5 is rotatably connected to one side of the fixed ring plate 2, and a connecting rod 51 is fixedly connected to one end of the support rod 5. Both the support rod 4 and the support rod 5 are in movable contact with the automotive wiring harness clamped on two adjacent elastic buckles 3.

[0036] Both support rod 4 and support rod 5 are semi-circular structures. When support rod 4 and support rod 5 form a near-circular support structure, since there are multiple wire grooves and multiple wire harnesses are arranged on the circular path, the diameter of the circular support structure is set to be relatively smaller than the diameter of the multiple wire harness paths. In this way, support rod 4 and support rod 5 can provide effective support for the wire harnesses. When multiple wire harnesses are assembled on the wire harness ring frame in a circular path, support rod 4 and support rod 5 can be set on the inner side of the multiple wire harnesses. In this way, the wire harnesses can obtain two connection points, thereby effectively preventing the wire harnesses from coming off the elastic buckle 3.

[0037] In this embodiment: a fixing block 8 is fixedly connected to one side of one end of the fixing ring plate 1, and a rotating rod 10 is fixedly connected to the other end of the support rod 4. The rotating rod 10 is damped and rotatably connected to the fixing block 8. A fixing block 29 is fixedly connected to one side of one end of the fixing ring plate 2, and a rotating rod 21 is fixedly connected to the other end of the support rod 25. The rotating rod 21 is damped and rotatably connected to the fixing block 29.

[0038] Both support rod 4 and support rod 5 can be rotated on one side of the wire harness ring bracket. The purpose of rotation is to facilitate the removal of the automotive wire harness from the elastic clip 3 when opening the wire harness ring bracket to remove the automotive wire harness. This is achieved by rotating support rod 4 and support rod 5 to a position perpendicular to the fixing ring plate 2. Similarly, when it is necessary to fix the automotive wire harness on the elastic clip 3, support rod 4 and support rod 5 can be rotated to the same horizontal plane as the fixing ring plate 2.

[0039] In this embodiment: a locking structure 6 is provided on the first fixed ring plate 1 and the second fixed ring plate 2. The first connecting rod 41 and the second connecting rod 51 are both connected to the locking structure 6. The locking structure 6 includes a first positioning block 61, which is fixedly connected to the side of the other end of the first fixed ring plate 1. A second positioning block 62 is fixedly connected to the side of the other end of the second fixed ring plate 2. Bolts 63 are threadedly connected to the first positioning block 61 and the second positioning block 62.

[0040] In use, by fixing the connecting rod 41 on support rod 4 and the connecting rod 51 on support rod 5 to positioning block 61 and positioning block 62 respectively, when fixing ring plate 1 and fixing ring plate 2 rotate to the docking state through the hinge, positioning block 61 and positioning block 62 can be brought close together horizontally. Then, by threading bolt 63 through positioning block 61 and positioning block 62, the position of connecting rod 41 and connecting rod 51 can be fixed, and the wire harness ring frame is also fixed.

[0041] In this embodiment: positioning grooves 12 are provided on the opposite surfaces of positioning block 1 61 and positioning block 2 62. Bolts 63 arranged on positioning block 1 61 and positioning block 2 62 pass through the positioning grooves 12. Connecting rod 1 41 and connecting rod 2 51 are respectively arranged in the corresponding positioning grooves 12 of positioning block 1 61 and positioning block 2 62. Thread grooves for threaded connection of bolts 63 are provided on connecting rod 1 41 and connecting rod 2 51.

[0042] The two positioning slots 12 can respectively place connecting rod 41 and connecting rod 51, which makes it convenient for bolts 63 to be threaded through positioning blocks 61 and 62 to fix connecting rod 41 and connecting rod 51.

[0043] In this embodiment: Alignment structure 7 is provided on connecting rod 1 41 and connecting rod 2 51. Alignment structure 7 includes limiting block 71. Limiting block 71 is fixedly connected to the outer surface of connecting rod 2 51. Limiting ring groove 72 is formed on the outer surface of connecting rod 1 41. Limiting block 71 is movably connected in limiting ring groove 72.

[0044] The advantage of the alignment structure 7 is that when it is necessary to fix the first support rod 4 and the second support rod 5 using the locking structure 6, in order to reduce the difficulty of simultaneously controlling the first support rod 4 and the second support rod 5 to be on the same horizontal plane, that is, the difficulty of the screw grooves on the first support rod 4 and the second support rod 5 to be coaxially aligned, the first support rod 4 is pulled down and rotated so that the limiting block 71 on the second connecting rod 51 is in a vertical state. Then the first connecting rod 41 is controlled to rotate until one end of the limiting ring groove 72 on the first connecting rod 41 abuts against the limiting block 71. In this way, the first connecting rod 41 and the second connecting rod 51 can be controlled to be in the same horizontal plane. This makes it easy to quickly connect the first connecting rod 41 and the second connecting rod 51 with the bolt 63. Moreover, since the limiting ring groove 72 is a local path on the outer surface of the first connecting rod 41, it can meet the rotation requirements of the first connecting rod 41 and the second connecting rod 51 to avoid the need for removing the automotive wiring harness, while satisfying the limiting abutment with the limiting block 71.

[0045] It is worth noting that if it is further necessary to provide an additional stable support point for fixing the automotive wiring harness, then in the automotive wiring harness retainer of this application, all the structures on one side of the wiring harness ring frame can be mirrored on the other side.
