In this embodiment, the pencil buckle adopts the plastics material, has certain elasticity.

As shown in fig. 1, in this embodiment, the secondary locking mechanism 2 is in the pre-installation position in the initial state before the harness is snap-fitted. When the wire harness fastening device is used, the primary lock bolt 11 is inserted into the vehicle body mounting hole 51 and then is elastically Zhang Kaisuo to complete primary locking, so that the wire harness fastening device is fastened and fixed on the vehicle body. The process of snap fitting the wire harness to the vehicle body is described as follows:

the first step: the wire harness buckle is pressed downwards, the primary lock bolt 11 is assembled into the vehicle body mounting hole 51, the primary lock bolt 11 is compressed inwards under the action of the extrusion force, and after the primary lock bolt 11 passes through the vehicle body mounting hole 51, the fins 111 of the primary lock bolt 11 are elastically opened to complete locking, as shown in fig. 6 and 7.

And a second step of: the secondary locking mechanism 2 is moved from the preassembly position to the locking position, as shown in fig. 8, at this time, the secondary locking mechanism 2 is embedded into the inner side of the primary locking bolt 11 to occupy the fin elastic movement space 16, so that the primary locking bolt 11 cannot bend inwards, and secondary locking is completed. After the wire harness is assembled, the final effect is shown in fig. 2, 3, 4 and 5.

The metal plate 5 of the vehicle body needs to be provided with a mounting hole 51 of the vehicle body, and the thickness of the metal plate 5 of the vehicle body and the shape and size of the mounting hole 51 of the vehicle body are required to be matched with the structural size of the portion of the primary lock tongue 11 of the buckle main body 1.

As shown in fig. 9 and 10, in this embodiment, the secondary locking mechanism 2 is L-shaped, a lower hook 21 is disposed at a first end of the secondary locking mechanism 2, and a return hook 14 corresponding to the lower hook 21 is disposed on the buckle main body 1. The second end of the secondary locking mechanism 2 is provided with an upper buckle 22, and the buckle main body 1 is provided with a buckle sleeve 12; when the secondary locking mechanism 2 is in the preassembly position of the guide rail groove 13, the upper buckle 22 of the secondary locking mechanism 2 is abutted against the outer edge of the buckle sleeve 12; when the secondary locking mechanism 2 is in the locked position of the guide rail groove 13, the upper buckle 22 is embedded into the buckle sleeve 12 of the buckle main body 1.

In this embodiment, as shown in fig. 8, two fins 111 are distributed on two opposite sides of the connection block 110. The number of the guide rail grooves 13 is two, and the guide rail grooves are respectively positioned at two sides of the buckle sleeve 12; the first end of the secondary locking mechanism 2 has two locking legs 23, and the lower hook 21 is disposed at the lower end of the locking legs 23. The two locking legs 23 are respectively positioned in the corresponding guide rail grooves 13; when the secondary locking mechanism 2 is in the locking position of the guide rail groove 13, the two locking legs 23 of the secondary locking mechanism 2 are respectively positioned in the corresponding fin elastic movement spaces 16.

As shown in fig. 6, 7, 9 and 10, before the secondary lock mechanism 2 is assembled to the buckle main body 1, the buckle main body 1 has a primary locking capability, and is assembled into the vehicle body mounting hole 51 by the primary lock tongue 11, and locked and fixed after being sprung open. The secondary locking mechanism 2 is then assembled to the pre-assembled position of the buckle body 1, as shown in fig. 13 and 14. The secondary locking mechanism 2 is embedded and attached in the guide rail groove 13 of the buckle main body 1 and is assembled in the preassembly position. In order to prevent the secondary locking mechanism 2 from falling off from the pre-installed position of the buckle main body 1, the lower hook 21 of the secondary locking mechanism 2 hooks the return hook 14 of the buckle main body, and the upper buckle 22 of the secondary locking mechanism 2 is pressed by the outer edge of the buckle sleeve 12 of the buckle main body 1, so that the secondary locking mechanism 2 is limited on the pre-installed position of the buckle main body 1 and cannot move or fall off. In addition, as can be seen from fig. 14, in the preassembly position, since the lower hook 21 of the secondary lock mechanism 2 does not occupy the fin elastic movement space 16 of the primary lock tongue 11 to the buckle main body 1, the primary lock tongue 11 can normally elastically move and be fitted to the vehicle body mounting hole 51. Finally, the secondary locking mechanism 2 is moved to the locking position of the buckle main body 1, as shown in fig. 15 and 16. The secondary locking mechanism 2 is shifted inwards along the guide rail groove 13 of the buckle main body 1, the upper buckle 22 of the secondary locking mechanism 2 is embedded into the buckle sleeve 12 of the buckle main body 1, meanwhile, the lower hook 21 of the secondary locking mechanism 2 is inserted into the fin elastic movement space 16 of the primary locking bolt 11, and the L-shaped turning part of the secondary locking mechanism 2 is propped against the bottom of the guide rail groove 13. At this locking position, in order to avoid secondary locking mechanism 2 to drop from buckle main part 1, buckle main part 1's guide rail groove 13 bottom is the L shape groove, and the L shape of locking mechanism 2 is restricted the position of bending, and buckle main part 1's buckle 12 blocks the last knot 22 of secondary locking mechanism 2 simultaneously, and secondary locking mechanism 2 just so is spacing at buckle main part 1's locking position, can not remove or drop. In addition, as is clear from fig. 16, in the locked position, since the locking leg 23 of the secondary locking mechanism 2 occupies the fin elastic movement space 16 of the primary lock tongue 11, the primary lock tongue 11 cannot move elastically any more, so that the secondary locking of the primary lock tongue 11 is completed, and the primary lock tongue 11 is prevented from coming out of the vehicle body mounting hole 51 for various reasons.

Further, it is determined whether the primary lock tongue 11 has been completely sprung out and fitted in place by whether the secondary lock mechanism 2 can be shifted from the pre-installation position to the lock position. As shown in fig. 17, after the primary lock tongue 11 is assembled to the vehicle body mounting hole 51, if the buckle is not assembled in place and the fin 111 is in a compressed and non-opened state, the fin elastic movement space 16 will be occupied, at this time, the secondary locking mechanism 2 will not be able to toggle into the fin elastic movement space 16 due to collision interference with the primary lock tongue 11, thereby reminding an operator that the primary lock tongue 11 is not assembled in place and needs to be assembled again.

Regarding the assembly of the wire harness and the buckle, both the left and right ends of the buckle body 1 are provided with wire harness binding points 15, and as shown in fig. 1, 4, 5, the wire harness 3 is fixed to the buckle body 1 by a binding member 4 (e.g., an adhesive tape or a tie).

As shown in fig. 1 and 2, in the present embodiment, a vehicle includes a body sheet metal and a wire harness clip; a vehicle body mounting hole 51 matched with the wire harness buckle is formed in the vehicle body metal plate 5; the wire harness clip described in this embodiment is adopted as the wire harness clip.

The pencil buckle in this embodiment for traditional once lock buckle, increased secondary locking mechanism, improved the locking reliability of pencil buckle greatly, avoided the risk that the pencil buckle drops. The wire harness sealing device has good use prospect at some key parts, such as a wire harness moving section, a position with a sealing requirement in a clamping manner and the like.

The above examples are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above examples, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principle of the present utility model should be made in the equivalent manner, and the embodiments are included in the protection scope of the present utility model.
