Description

Technology Field

[0001] The present invention relates to a cable tie. One embodiment may be used for fixing a distribution box, a switchboard, a wire tray, or an electrical harness. Background Technology

[0002] Cable ties are generally widely used in electrical installation sites to secure or organize multiple wires or electrical harnesses. These cable ties feature a locking head at one end and a band extending from the other end with ratchet-shaped teeth; they are used by passing the band through the head to tighten and secure it, after which the remaining band portion is cut off.

[0003] However, conventional cable ties often struggle to secure sufficient fastening force when fixing thick wire bundles, dense wiring inside distribution boxes, or heavy electrical conduits, resulting in unstable fastening or frequent breakage of the band when using only a single tie. Consequently, work efficiency is reduced, requiring the overlapping use of multiple cable ties or the use of separate tools to cut the remaining parts, and there are disadvantages in terms of safety and orderliness during on-site construction.

[0004] Korean Published Patent Application No. 10-2024-0175798 The problem to be solved

[0005] The present invention aims to provide a cable tie that has excellent tensile strength and can be used stably even under conditions requiring high tension.

[0006] In addition, the present invention has excellent fixing power, so the band does not detach from the head due to reasons such as damage to the head.

[0007] In addition, the present invention eliminates the need to remove residual bands, thereby increasing the convenience of the fixing process. means of solving the problem

[0008] A cable tie according to an embodiment of the present invention comprises: a band member having teeth disposed on at least one surface; a first head disposed at one end of the band member and having a hollow through which the other end of the band member passes; and a second head disposed at a certain distance from the first head and having a hollow through which the other end of the band member passes.

[0009] The first head and the second head each include a first tooth profile and a second tooth profile that prevent the inserted band member from moving in the opposite direction by engaging with the tooth.

[0010] The hollow of the first head and the hollow of the second head are open in a direction from one end to the other end of the band member, and the band member passing through the hollow of the first head can be inserted into the hollow of the second head.

[0011] Among the above band members, the portion positioned between the first head and the second head may have a higher tensile strength compared to other portions.

[0012] The above band member may include a second tooth and a first tooth disposed on one side and the other side, respectively. The first head may include a first upper tooth profile and a first lower tooth profile that engage with each of the second tooth and the first tooth. The second head may include a second upper tooth profile and a second lower tooth profile that engage with each of the second tooth and the first tooth.

[0013] The distance between the first head and the second head may be nl+xl (where l is the distance between the teeth of the band member, n is a natural number, and x is 0.4 to 0.6). In this case, when the band member is inserted into and fixed to the first head and the second head, the distance of the portion of the band member positioned between the first head and the second head may be shorter than the distance of the portion of the band member passing through the first head and the second head, and the upper part of the second head may be positioned to be inclined in a direction away from the first head. Effects of the invention

[0014] The cable tie according to the embodiment of the present invention has excellent tensile strength and can be used stably even under conditions requiring high tension.

[0015] In addition, the present invention has excellent fixing power, so the band does not detach from the head due to reasons such as damage to the head.

[0018] Preferred embodiments of the present invention are described below with reference to the attached drawings. However, embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. Furthermore, embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art. Accordingly, the shapes and sizes of elements in the drawings may be exaggerated for clearer explanation, and elements indicated by the same reference numerals in the drawings are the same elements. Additionally, the same reference numerals are used throughout the drawings for parts having similar functions and operations. Furthermore, throughout the specification, the term "comprising" a component means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0020] FIGS. 1 and FIGS. 2 are views of a cable tie (100) according to an embodiment of the present invention from different directions. Referring to FIGS. 1 and FIGS. 2, the cable tie (100) according to an embodiment of the present invention comprises: a band member (110) having teeth (111) arranged on at least one surface; a first head (120) arranged at one end of the band member (110) and having a hollow through which the other end of the band member (110) passes; and a second head (130) arranged at a certain distance from the first head (120) and having a hollow through which the other end of the band member (110) passes.

[0022] The above cable tie (100) may be made of materials such as nylon or polypropylene, and may be manufactured in a state where all components are integrally combined by injection molding.

[0024] The above band member (110) serves to wrap around or bind and secure an object. The above band member (110) may have a linear structure in the form of an elongated band and includes teeth (111) arranged on at least one surface.

[0025] The first head (120) and the second head (130) are disposed at one end portion of the band member (110). The one end portion corresponds to 5 to 15%, preferably 10 to 15%, of the total length of the band member (110). The one end portion may have a higher tensile strength than other portions of the band member (110). Two heads are disposed at the one end portion and are continuously exposed to the force (tension, etc.) applied to the first head (120) and the second head (130). Due to this external force, the first head (120) and the second head (130) may detach from the band member (110) or the length between the first head (120) and the second head (130) may increase, in which case the fixing function cannot be properly performed. Additionally, when the other end of the band member (110) passes through the first head (120) and is inserted into the second head (130), if the end portion does not have sufficient tensile strength, it may bend, making it difficult to insert the second head (130).

[0026] To increase the tensile strength of the above-mentioned end portion, the above-mentioned end portion may not include teeth (111) and may be 5 to 10% thicker than other portions. Additionally, it may be reinforced by forming ribs on the edge of one side. In another embodiment, the above-mentioned end portion may have a square or hexagonal pattern formed as protrusions or grooves on one side and / or the other side to increase strength.

[0027] The other end portion of the band member (110) is the part that the worker pulls with their hand. The other end portion may include a shape such as a protrusion or a groove to prevent the worker's hand from slipping. Additionally, the other end portion may have a shape that tapers toward the other end to allow for easy insertion into the first head (120) and the second head (130).

[0028] The above teeth (111) engage with the teeth of the first head (120) and the second head (130) to prevent the connection from coming undone. The teeth (111) may be formed in numbers ranging from several to tens, and may be formed by creating grooves or protrusions on one or the other side of the band member (110). The teeth (111) may be placed over a wide area from one end to the other end of the band member (110), but may not be placed in the area (one end portion) between the first head (120) and the second head (130). If the teeth (111) are placed between the first head (120) and the second head (130), the tensile strength of that portion may be weakened and it may bend easily, potentially deforming or breaking under high tension. In one embodiment, the teeth (111) may not be placed in the other end portion of the band member (110).

[0029] In the embodiments of FIGS. 1 and 2, the teeth (111) are formed only on the other side of the band member (110), and in the embodiments of FIGS. 4 and 5, the first teeth (111a) and the second teeth (111b) are formed on both the other side and one side of the band member (110), respectively. By forming the teeth (111a, 111b) on both sides, the binding strength can be increased.

[0031] The first head (120) and the second head (130) secure the band member (110). The present invention includes two heads so that the band member (110) passes through the two heads sequentially to be secured, thereby enabling a stronger connection.

[0032] Additionally, the hollow of the first head (120) and the hollow of the second head (130) are open in a direction from one end to the other end of the band member (110), and the band member (110) that has passed through the hollow of the first head (120) can be inserted into the hollow of the second head (130). In the case of a general cable tie, the hollow of the head is open in a direction perpendicular to the length direction of the band, so even if two heads are placed, the band cannot pass through the heads sequentially, and the head is subjected to excessive stress, resulting in a shortened lifespan.

[0033] The first head (120) and the second head (130) have a hollow through which the band member (110) passes. Referring to FIGS. 3 and 6, the first head (120) and the second head (130) may be rectangular. The hollow may have a shape corresponding to the shape of the band member (110), and a tooth profile that engages with the gear (111) may be arranged on the upper or lower part.

[0034] In the embodiments of FIGS. 1 to 3, when the tooth (111) is positioned on the other side of the band member (110), the first tooth (121) and the second tooth (131) may be positioned on the lower side of the first head (120) and the second head (130). If the tooth (111) is positioned on one side of the band member (110), the first tooth (121) and the second tooth (131) may be positioned on the upper side of the first head (120) and the second head (130). The first tooth (121) and the second tooth (131) may have an elastic structure. This may be identical or similar to the tooth structure of a general cable tie (100). Specifically, it may be L-shaped. When the band member (110) is inserted, the first tooth (121) and the second tooth (131) are pressed downward so that the band member (110) can be easily inserted, and when insertion is completed, the first tooth (121) and the second tooth (131) are restored to their original shape and coupled with the gear (111). The first tooth (121) and the second tooth (131) are connected to and positioned at the entrance of the hollow and may have a slanted shape such that the height increases toward the exit. The first tooth (121) and the second tooth (131) can be coupled with the gear (111) at the exit of the hollow.

[0035] In the embodiments of FIGS. 4 to 6, when the tooth (111) is positioned on both one side (second tooth (111b)) and the other side (first tooth (111)) of the band member (110), the first head (120) and the second head (130) may include tooth profiles on both the upper and lower sides. In this case, the tooth profile of the first head (120) may be referred to as the first upper tooth profile (121b) and the first lower tooth profile (121a), and the tooth profile of the second head (130) may be referred to as the second upper tooth profile (131b) and the second lower tooth profile (131a).

[0036] The first lower tooth (121a) and the second lower tooth (131a) may have an elastic structure. This may be identical or similar to the tooth structure of a general cable tie (100). Specifically, it may be L-shaped. When the band member (110) is inserted, the first lower tooth (121a) and the second lower tooth (131a) are pressed downward to allow the band member (110) to be easily inserted, and when insertion is complete, the first lower tooth (121a) and the second lower tooth (131a) are restored to their original shape and combined with the first tooth (111). The first lower tooth (121a) and the second lower tooth (131a) are connected to and positioned in the inlet portion of the hollow, and may have a slanted shape such that the height increases toward the outlet. The first lower tooth profile (121a) and the second lower tooth profile (131a) can be combined with the first tooth (111) in the hollow exit portion.

[0037] The first upper tooth profile (121b) and the second upper tooth profile (131b) may be protrusions that protrude downward from the upper part of the hollow. The first upper tooth profile (121b) and the second upper tooth profile (131b) may be coupled with the second tooth (111b) at the exit portion of the hollow. That is, the first lower tooth profile (121a) and the second lower tooth profile (131a) and the first upper tooth profile (121b) and the second upper tooth profile (131b) respectively connect the first tooth (111) and the second tooth (111b) from above and below at the same portion (the exit portion of the hollow), thereby exerting a strong binding force.

[0039] The distance L (length of one end portion of the band member (110)) between the first head (120) and the second head (130) may be nl+xl (where l is the distance between the teeth (111) of the band member (110), n is a natural number, and x is 0.4 to 0.6). That is, L does not correspond to a multiple of the distance between the teeth (111). In this case, when the band member (110) is inserted into and fixed to the first head (120) and the second head (130), the distance (L) of the portion of the band member (110) positioned between the first head (120) and the second head (130) may be positioned shorter than the distance (M) of the portion of the band member (110) that passes through the first head (120) and the second head (130), and the upper part of the second head (130) may be positioned to be inclined in a direction away from the first head (120) (see FIG. 7). Through this, the cable tie (100) can form a stable circular shape overall, and the first head (120) and the second head (130) can receive force evenly, thereby increasing durability.

[0041] The present invention is not limited by the embodiments described above and the attached drawings, but is intended to be limited by the appended claims. Accordingly, various substitutions, modifications, and changes may be made by those skilled in the art within the scope of the technical concept of the present invention as described in the claims, without departing from the technical spirit of the invention, and such are also to be considered to fall within the scope of the present invention.
