Description

Technical field

[0001] The utility model relates to the technical field of wire harnesses, in particular to the technical field of wire harness buckles. [Background Technology]

[0002] Wiring harnesses are used to connect devices and transmit power. They typically contain one or more wire cores and are protected by a sheath. With the continuous advancement of vehicle technology, vehicle structures are becoming increasingly complex, and the number of electrical components used in vehicles is increasing. To meet these functional requirements, the number of wiring harness circuits is also increasing dramatically.

[0003] In a car, the wiring harness is generally routed along the inner surface of the sheet metal and is quickly fixed using a wiring harness clip. Existing wiring harness clips usually have a ring structure that can encircle the wiring harness at one end, and the other end is directly connected to the sheet metal by plugging. In order to facilitate the rapid encirclement of the wiring harness, such wiring harness clips usually have an opening at the ring structure for the wiring harness to enter and exit, such as a wiring harness quick fixing clip with publication number CN118198948A. Some manufacturers will also add connectors and interfaces at the opening to realize the opening and closing of the opening, such as an elliptical wiring harness clip with announcement number CN201846027U and an elliptical wiring harness clip with publication number CN114435265A. However, the connectors and interfaces can easily become detached due to factors such as vibration during use, which in turn causes the wiring harness to loosen. In addition, since the ring cavity size of the annular structure of the above-mentioned wiring harness clip is fixed, it can only fix wiring harnesses of a specific size. This means that users often need to prepare wire harness clips of different sizes according to wire harness sizes, which increases inventory pressure. [Utility Model Content]

[0004] The purpose of the utility model is to solve the problems in the prior art and to propose a combined clip-type wiring harness buckle, which is not only quick and simple to install, but also adaptable to wiring harnesses of different sizes.

[0005] To achieve the above-mentioned purpose, the utility model proposes a combined clamp-type wiring harness buckle, including an upper clamp and a lower clamp, the upper clamp including an upper base block and an upper rack, the bottom surface of the upper base block is provided with an upper notch and upper racks located on both sides of the upper notch, the upper base block can be engaged with the sheet metal through the upper rack and the spacing can be adjusted, the lower clamp includes a lower base block, the lower base block is slidably connected to the upper base block and the top surface is provided with a lower notch, the upper notch and the lower notch can be combined together to form a clamping cavity for clamping the wiring harness.

[0006] Preferably, a plurality of vertically arranged sliding grooves are provided on the upper base block, and a sliding column correspondingly slidably connected to each sliding groove is installed on the lower base block.

[0007] Preferably, the surface of the upper base block is further provided with scale lines corresponding to each slide groove.

[0008] Preferably, the upper notch is in the shape of an equilateral triangle, and the lower notch is in the shape of an inverted triangle.

[0009] Preferably, an upper gasket is applied to the upper concave surface of the upper recess, and a lower gasket is applied to the lower concave surface of the lower recess.

[0010] Preferably, the surface of the upper rack is provided with a tooth portion that matches the tooth groove of the sheet metal, and the lower end of the upper rack is provided with a guide head portion that gradually narrows from top to bottom.

[0011] Preferably, the upper end of the upper rack is provided with a screw head which can be screwed into a screw hole located on the bottom surface of the upper base block.

[0012] Preferably, the bottom end of the lower base block is further provided with an outer flange.

[0013] Beneficial effects of the utility model:

[0014] 1) An upper rack is added to the bottom surface of an upper base block with an upper notch to achieve connection and spacing adjustment between the upper base block and the sheet metal. A lower base block with a lower notch is provided in a sliding manner with the upper base block. As the upper base block is pressed down to reduce the spacing between the upper base block and the sheet metal, the clamping cavity formed by the upper and lower notches is simultaneously reduced to clamp the wiring harness. This not only enables direct plug-in assembly like traditional wiring harness clips, with the characteristics of quick and simple installation, but also can adapt to wiring harnesses of different sizes, effectively reducing inventory pressure;

[0015] 2) By making the upper notch and the lower notch into an equilateral triangle and an inverted triangle respectively, and applying an upper gasket and a lower gasket in the upper notch and the lower notch respectively, the wiring harness can be clamped synchronously and stably through four contact points, and the wiring harness can be effectively prevented from being clamped;

[0016] 3) The upper and lower base blocks are connected by sliding grooves and sliding posts, and multiple scale lines are added to the surface of the upper base block, making it easier for users to observe and accurately control the size of the clamping cavity in real time according to the scale lines;

[0017] 4) By arranging screw heads and guide heads at the upper and lower ends of the upper rack respectively, it is not only convenient for the upper rack to be smoothly plugged into the sheet metal, but also enables the upper rack to be disassembled and replaced as needed.

[0018] The features and advantages of the present invention will be described in detail through embodiments with reference to the accompanying drawings.

[Specific implementation method]

[0024] See Figures 1 to 4 The utility model combines a pair of clamp-type wiring harness buckles and includes an upper clamp 11 and a lower clamp 12. The upper clamp 11 includes an upper base block 111 and an upper rack 112. The bottom surface of the upper base block 111 is provided with an upper notch 1111 and upper racks 112 located on both sides of the upper notch 1111. The upper base block 111 can be engaged with the sheet metal 2 through the upper rack 112 and the spacing can be adjusted. The lower clamp 12 includes a lower base block 121. The lower base block 121 is slidably connected to the upper base block 111 and has a lower notch 1211 on the top surface. The upper notch 1111 and the lower notch 1211 can be combined to form a clamping cavity 13 for clamping the wiring harness 3.

[0025] The upper base block 111 is provided with a plurality of vertically arranged sliding grooves 1112 , and the lower base block 121 is provided with sliding posts 122 that are slidably connected to the sliding grooves 1112 in a one-to-one manner.

[0026] The surface of the upper base block 111 is further provided with scale lines 1113 corresponding to each of the slide grooves 1112 .

[0027] The upper notch 1111 is in the shape of a regular triangle, and the lower notch 1211 is in the shape of an inverted triangle.

[0028] An upper gasket 113 is applied to the upper concave surface of the upper recess 1111 , and a lower gasket 123 is applied to the lower concave surface of the lower recess 1211 .

[0029] The surface of the upper rack 112 is provided with a tooth portion 1121 that matches the tooth groove of the sheet metal 2, and the lower end of the upper rack 112 is provided with a guide head portion 1122 that gradually narrows from top to bottom.

[0030] The upper end of the upper rack 112 is provided with a screw head 1123 which can be screwed into a screw hole located on the bottom surface of the upper base block 111 .

[0031] The bottom end of the lower base block 121 is further provided with an outer flange 1212 .

[0032] Working process of this utility model:

[0033] During use, first pass the wiring harness through the combined clamp-type wiring harness buckle 1 along the clamping cavity 13. Next, press down on the upper base block 111, causing each upper rack 112 to gradually pass through the sheet metal 2 along its corresponding tooth grooves. As the distance between the upper base block 111 and the sheet metal 2 gradually decreases, the sheet metal 2 will simultaneously push up against the lower base block 121 (and each slide post 122 will move upward along its corresponding slide groove 1112), gradually shrinking the clamping cavity 13. When the clamping cavity 13 just clamps the wiring harness, stop pressing down on the upper base block 111.

[0034] Because the meshing teeth and tooth portions 1121 only allow the upper base block 111 to move downward (i.e., only allow the upper base block 111 to move toward the side closer to the sheet metal 2), if the combined clip-type wiring harness buckle 1 needs to be removed, the upper rack 112 can be cut between the upper base block 111 and the sheet metal 2, and then the guide head 1122 can be twisted to remove the remaining upper rack 112 connected to the upper base block 111. At the same time, the guide head 1122 can be pulled down to remove the remaining upper rack 112 connected to the sheet metal 2. In addition, if the combined clip-type wiring harness buckle 1 needs to be reused, a new upper rack 112 can be screwed into the top of the upper base block 111.

[0035] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the scope of protection of the present invention.
