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] Wire harnesses can be used to connect devices and transmit electricity, etc. They usually contain one or more wire cores and are covered with a sheath as a protective layer. With the continuous advancement of vehicle functional technology, the structure of automobiles is becoming more and more complex, and more and more electrical components are used in automobiles. In order to meet the functional requirements of automobiles, the number of circuits in the wire harness is also increasing sharply.

[0003] In a car, the wiring harness is generally routed along the inner surface of the sheet metal and quickly fixed with a wiring harness buckle. The utility model with announcement number CN219779660U discloses a quick-fix wiring harness buckle. The wiring harness buckle includes a fastener and an elastic baffle, which can be used to elastically press the wiring harness against the side of the restraining strip away from the opening by loosening the elastic baffle when in use. Although this type of wiring harness buckle has a simple structure and is very quick to install, there is a problem that the wiring harness is easy to bounce in the loop channel after installation. This is because the elastic baffle moves to the bottom of the gap by its own elastic force, and still has space to move upward along the gap (that is, when the wiring harness is subjected to vibration or extrusion, it can drive the elastic baffle to bounce upward together in the loop channel). [Contents of the utility model]

[0004] The purpose of the utility model is to solve the problems in the prior art and to provide a straight-insert elastic wire harness buckle, which is not only very simple and convenient to assemble, but also does not cause wire harness bouncing.

[0005] To achieve the above-mentioned purpose, the utility model proposes a straight-insert elastic wire harness buckle, including a fastener, an elastic baffle, a limit column and a base column, the fastener includes a restraining strip, a connecting strip and a clamping head, the restraining strip is bent into a circle with an opening, the two connecting strips are respectively fixed at the two ends of the restraining strip and are parallel, the two clamping heads are respectively arranged on the opposite sides of the two connecting strips, a plurality of the limit columns are arranged around the ring channel and are fixed on the restraining strip, one end of the elastic baffle is indirectly connected to the restraining strip through the base column and is arranged close to the opening, and the other end is abutted against one of the limit columns and has an elastic tendency to deviate toward the opening.

[0006] Preferably, the opposite sides of the two clamps are respectively provided with inclined surfaces, and the distance between them is gradually increased from the end far from the opening to the end close to the opening.

[0007] Preferably, platform portions are provided at the connection points between the restraining strip and the two connecting strips.

[0008] Preferably, the free end of the elastic blocking piece is provided with a warped portion bent toward the opening.

[0009] Preferably, the restraining strip is provided with a plurality of insertion holes arranged around the ring body channel, and each of the limiting posts passes through the corresponding insertion hole one by one and can move along the insertion hole.

[0010] Preferably, each of the limiting columns is provided with an expansion head at one end facing away from the elastic blocking piece, and each of the limiting columns can be positioned by inserting the expansion head into the corresponding insertion hole.

[0011] Preferably, each of the limiting columns is provided with an outward flange at one end close to the elastic blocking piece.

[0012] Beneficial effects of the utility model:

[0013] 1) By bending the tie bar into a circle with an opening as the main body of the fastener, two connecting bars are arranged in parallel at both ends of the tie bar, and two clamps are arranged on the opposite sides of the two connecting bars, so that the opening can face the bar body channel between the two connecting bars, which not only makes the tie bar have certain expansion and contraction properties, but also can use the sheet metal to directly close the opening after the two clamps pass through the preset holes of the sheet metal, so that the assembly is very simple and convenient;

[0014] 2) By adding a plurality of limit columns arranged around the ring body channel on the restraining strip, one end of the elastic baffle is indirectly connected to the restraining strip through the base column and is arranged close to the opening, and the other end of the elastic baffle with an elastic tendency to deviate toward the opening is abutted against one of the limit columns, so that the size of the clamping space between the elastic baffle and the restraining strip can be adjusted according to the abutting position of the elastic baffle, thereby meeting the assembly of wire harnesses of different sizes, improving the adaptability of use, reducing inventory pressure, and since the clamped wire harness has no space to continue to move toward the opening, there is no problem of the wire harness bouncing in the ring body channel;

[0015] 3) By arranging a plurality of insertion holes on the restraining strip for each limiting column to pass through, and respectively arranging expansion heads and outer flanges at both ends of each limiting column, the extrusion fit between the expansion head and the insertion hole can be utilized to keep the designated limiting column in an outwardly extending outer flange shape and hooked against the elastic baffle, and the remaining limiting columns can also retract the outer flanges to avoid affecting the upward and downward movement of the elastic baffle.

[0016] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.

The two connecting strips 12 are respectively fixed at the two ends of the restraining strip 11 and are parallel to each other. The two clamping heads 13 are respectively arranged on the opposite sides of the two connecting strips 12. A plurality of limiting columns 3 are arranged around the ring channel and fixed on the restraining strip 11. One end of the elastic baffle 2 is indirectly connected to the restraining strip 11 through the base column 4 and is arranged close to the opening 111, while the other end abuts against one of the limiting columns 3 and has an elastic tendency to deviate toward the opening 111.

[0025] The opposite sides of the two clamping heads 13 are respectively provided with inclined surfaces so that the distance between them gradually increases from the end far from the opening 111 to the end close to the opening 111 .

Then, according to the outer diameter of the wire harness, move the elastic baffle 2 and make the warping portion 21 hook and abut against one of the limit posts 31. At this time, the wire harness is clamped between the tie bar 11 and the elastic baffle 2 at the side of the tie bar 11 away from the opening 111. Finally, the fastener 1 is plugged in the direction in which the two clamps 13 face the preset holes of the sheet metal 5, so that the platform portion 14 and the two clamps 13 are located on both sides of the sheet metal 4 respectively.

[0035] Working process of this utility model:

[0036] Before adjusting the position of the elastic baffle 2 according to the outer diameter of the wire harness, Figure 5 As shown in the arrow direction, the designated limiting column 3 (i.e., the limiting column 3 against which the elastic blocking piece 2 abuts) is pressed until its expansion head 31 is squeezed into the insertion hole 112, thereby achieving the positioning of the limiting column 3. At this time, the limiting column 3 is in a state where the outer flange 32 extends (see Figure 5 ), while the other limit posts are in the shape of outer flange 32 inwardly retracted (see Figure 4 ). Then, the raised portion 21 of the elastic blocking piece 2 is hooked and pressed against the limiting column 3 between the restraining strip 11 and the outwardly extending outer flange 32 .
