Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Embodiment one:

as shown in fig. 2-5, a buckle includes a buckle body 1, the buckle body is formed integrally by metal materials, the buckle body 1 includes a limiting portion 2 and a fixing portion 3, the fixing portion 3 is located at one side of the limiting portion 2, and the limiting portion 2 and the fixing portion 3 are P-shaped. The hollow structure 25 is arranged in the middle of the buckle body, and through the hollow structure, the raw material cost is reduced on one hand, and meanwhile, the weight of the buckle is reduced. The surface of the limiting part 2 is dipped and molded with a protective layer 9, and the protective layer 9 is usually made of softer materials. In the production process of the buckle, firstly, metal materials are processed into the shape of the buckle body, and then, the protective layer 9 is formed in a plastic dipping mode, so that the protective layer 9 and the buckle body are tightly adhered together, the buckle body 1 and the protective layer 9 cannot be separated due to factors such as cable play and vibration, and therefore, the cable in the limiting part 2 is more effectively prevented from being worn in the vibration process, and the buckle is particularly suitable for limiting of a vehicle body cable. The metal material inside effectively ensures that the buckle can not take place deformation when receiving certain external force.

Generally, the thickness of the protective layer is 0.5-1mm, so that on one hand, the cable in the limit part 2 can be prevented from being worn due to vibration, and on the other hand, cost can be effectively saved.

Because the surface of the limiting part is provided with the flexible protective layer, the protective layer can effectively prevent the cable from being worn. Even if vibration occurs, the position of the limiting part relative to the flexible protective layer is unchanged, so that the cable abrasion caused in the long-term running process of the automobile is prevented.

The limiting part 2 comprises a bottom wall 24, a transition part 23 connected with the bottom wall and a clamping arm 22 connected with the transition part, and in a clamping closed state, the bottom wall 24, the transition part 23 and the clamping arm 22 are enclosed to form a limiting channel for a cable to pass through. In the free state, the bottom wall 24 and one end of the clamping wall 22 form an opening 6, so that a cable can conveniently enter the limiting part 2 from the opening 6, when an external force is applied to the clamping arm 22, the clamping arm 22 can move towards the bottom wall 24 and contact with the bottom wall 24, and after the bottom wall 24 contacts with the clamping arm 22, the cable can be effectively limited in the limiting part 2 to prevent falling.

The first engaging portion 221 is provided at one end of the engaging arm 22, and the bottom wall 24 is provided with a second engaging portion 241 which is matched with the first engaging portion 221. The second buckling part 241 is strip-shaped, the upper portion of the second buckling part 241 is provided with a convex hull 242, the lower side of the convex hull 242 is provided with a tongue groove 244, the first buckling part 221 is provided with a convex tongue 222, when external force is applied downwards to the clamping arm 22, the clamping arm 22 gradually approaches the bottom wall 24, the convex tongue 222 contacts with the convex hull 242 and pushes the upper portion of the second buckling part 241 to deform outwards, and the convex tongue 222 continuously moves downwards to the lower side of the convex hull 242, so that the convex hull 232 limits the convex tongue 222 below the convex hull 242, and primary pre-buckling of the buckle is realized. If external force is continuously applied to the clamping arm 22, the protruding tongue 222 continues to move downwards along the second buckling portion 241 into the tongue groove 244, and in this embodiment, the tongue groove 244 is a square through hole, and it can be understood that the tongue groove may also be a concave groove body. When tab 222 enters tongue groove 244, the upper edge of tongue groove 244 prevents upward movement of the tab, thereby confining tab 222 within tongue groove 244, and achieving a secondary pre-snap of the snap. The primary pre-buckling and the secondary pre-buckling are different in that the secondary pre-buckling has better buckling effect, namely, the pre-buckling state is more stable. Of course, if it is desired to open the clasp that has been pre-buckled, the secondary pre-buckling requires more effort.

When the buckle that has been buckled in advance needs to be opened, the top 243 of the second buckling part 241 is pushed outwards, and the tongue 222 can be separated from the convex hull 242, so that the buckle is opened. When the assembly is produced, the buckle can be assembled on the cable firstly, then the first buckling part and the second buckling part are buckled, the pre-installation of the buckle on the cable before being installed on the vehicle body is realized, and the buckle can be effectively prevented from falling off in the assembly transportation process.

The spacing portion 2 is provided with a first spacing block 21 and a second spacing block 26 for separating cables at intervals, the first spacing block 21 extends downwards from the upper portion of the spacing portion 2, the second spacing block 26 is arranged opposite to the first spacing block 21, the shape of the second spacing block 26 is matched with the shape of the cables, a gap 7 is arranged between the first spacing block 21 and the second spacing block, the first spacing block 21 and the second spacing block 22 divide a channel into a first sub-channel 201 and a second sub-channel 202, the gap 7 is smaller than the outer diameter of the cables in a buckling closed state, and the cables cannot enter the other sub-channel from one sub-channel through the gap 7. When the bottom wall 24 and the clamping arm 22 are in a free state, the cable can enter the first sub-channel 201 and the second sub-channel 202 through the opening 6 and the gap 7.

The fixing portion 3 includes a first fixing portion 31 extending from the bottom wall 24 and a second fixing portion 32 extending from the clamping arm 22, the first fixing portion is provided with a first through hole 33, the second fixing portion is provided with a second through hole 34, the second through hole corresponds to the first through hole, when an external force is applied to the clamping arm 22 to contact the bottom wall, the second through hole 34 is located approximately above the first through hole 33, when a buckle with a cable pre-installed is installed on a vehicle body, only the fixing portion and the vehicle body need to be fixed together, that is, a screw passes through the first through hole 33 and the second through hole 34 to be fixedly connected with the vehicle body, so that the bottom wall 24 and the clamping arm 22 are fixed together on one hand, and the buckle can be effectively fixed at a position required by the vehicle body on the other hand.

The buckle is arranged on the cable at the assembly station in a pre-installation mode, so that the assembly time of a main production line can be effectively reduced, the separation of the production line stations is more flexible, and the production efficiency is further improved.

Embodiment two:

as shown in fig. 6, the difference between the present embodiment and the first embodiment is that the shape of the buckle and the arrangement of the sub-channels are different. When the buckle is in the buckling state, the buckle body 1' is triangular, the body 1' comprises three spacing blocks 21' arranged on the inner periphery, the body 1' forms a protective layer 9' through dipping, and the spacing blocks 21' divide the channel into a first sub-channel 201', a second sub-channel 202' and a third sub-channel 203' which are distributed in a triangular mode. The advantage of this embodiment is that it can limit three cables simultaneously by one buckle, thus being more suitable for being arranged at a node with three cables.

It is understood that the distribution manner of the sub-channels may be quadrilateral, polygonal, circular or elliptical, and the number of the sub-channels may be one or more. The distribution mode and the number of the cable spacing device mainly depend on the space shape of the buckle and the number of the cable spacing device needed by the node. A plurality of cables are limited simultaneously through one buckle, so that more use scenes are provided, the workload of fixing the buckle and the vehicle body is reduced, and the production efficiency is improved.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
