Description

Technical Field

[0001] The utility model belongs to the field of wiring harnesses used in car chassis, and particularly relates to a buckle-free ultrasonic welding waterproof protective shell. Background Art

[0002] With the development of society, the application of wiring harnesses is becoming more and more extensive. In the application of multiple wiring harnesses, connecting terminals are needed to concentrate the wiring harnesses. The ends of the current connecting terminals generally use buckles to bundle multiple wiring harnesses, but the disadvantages are that they are easy to be damaged, especially the buckle position, and the waterproof effect is poor, and the overall aesthetics and integrity are also relatively poor. Utility Model Content

[0003] In view of the above problems, the utility model provides a buckle-free ultrasonic welding waterproof protective shell.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is that the utility model provides a buckleless ultrasonic welding waterproof protective shell, including a terminal connector, and a buckleless protective shell is arranged at the tail of the terminal connector.

[0005] Preferably, the buckleless protective shell includes a protective shell A and a protective shell B configured to cooperate with the protective shell A, and the protective shell A and the protective shell B are sealed and bonded by ultrasonic welding.

[0006] Preferably, the protective shell A is provided with an alignment protrusion, and the protective shell B is provided with an alignment groove that cooperates with the alignment protrusion.

[0007] Preferably, the rear portion of the clipless protective shell is provided with a hose clip groove for clip-on sealing of the hose.

[0008] Compared with the prior art, the advantages and positive effects of the utility model are:

[0009] 1. The utility model adopts a buckle-free shell protection mode to achieve the sealing of the terminal connector, which is not only beautiful, but also highly waterproof and avoids unnecessary troubles caused by buckle damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the following is a brief introduction to the drawings required for use in the description of the embodiments. Obviously, the drawings described below are some embodiments of the utility model.

[0014] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0015] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0016] Embodiment 1, as Figure 1-Figure 2 As shown, the utility model provides a snap-free ultrasonic welding waterproof shell, including a terminal connector, and a snap-free shell is arranged at the tail of the terminal connector. As can be seen from the figure, the positional relationship between the two, but it should be noted here that there are many types of terminal connectors, and similarly there are many types of snap-free shells. The utility model patent mainly highlights the snap-free sealing mode of the tail shell.

[0017] Let’s talk about the design and structure of the clipless case in detail.

[0018] like Figure 2 As shown, the buckle-free protective shell includes a protective shell A and a protective shell B, and the two are designed to cooperate with each other, that is, the two can form a sealed body with the terminal connector. Since there is no buckle fixation and screw connection between the two, in order to ensure the sealing and connectivity of the two, this patent adopts ultrasonic welding at the connecting gap between the two for sealing and bonding. The advantage of this design is that it is more integrated and beautiful in appearance, has a better sealing effect from a practical point of view, and truly achieves a waterproof effect.

[0019] from Figure 2 It can also be seen that in order to facilitate the two protective shells to be better aligned together, the inventors set an alignment protrusion on the protective shell A and an alignment groove on the protective shell B.

[0020] The tail of the buckleless protective shell is generally connected to a sealing hose. In order to better fix it, a hose clamping groove is provided on the protective shell A and the protective shell B. Figure 2 It can be seen that there are corresponding structures on both shells, which occupy most of the shell A. The protruding parts are also for better alignment and fixation of the two shells.

[0021] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
