Description

Technical Field

[0001] This utility model relates to the field of Type-C connector technology, specifically to a high-temperature resistant and wear-resistant Type-C connector. Background Technology

[0002] The Type-C connector (USB Type-C) is a universal serial bus (USB) interface standard that features reversible pluggability, high transmission speed, and multi-functional integration, and is widely used in modern electronic devices.

[0003] However, the current Type-C connector has a simple structure, with its outer metal shell directly exposed. During insertion, the end face of the metal shell is prone to collision with the outer wall of the device due to misalignment with the interface, which can easily cause damage to the end. Furthermore, prolonged insertion and removal can cause wear on the outer surface of the metal shell, affecting the stability of subsequent insertions. In addition, the current Type-C connector has poor high-temperature resistance, which affects its service life. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-temperature and wear-resistant Type-C connector. The wear-resistant part can avoid direct collision with the end of the metal shell, while the spring piece increases the friction between the connector and the interface, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a high-temperature and wear-resistant Type-C connector, comprising an insulating body and a metal shell sleeved on the outside of the insulating body, one end of the insulating body extending outward from the inside of the metal shell and expanding outward to form a wear-resistant part, and mounting grooves provided on both sides of the metal shell, each mounting groove having a mounting plate inside, and spring pieces installed on the outer surface of each mounting plate.

[0006] As a preferred technical solution, the cross-sections of the assembly slot and the assembly plate are both trapezoidal, the outer side of the assembly plate is lower than the outer surface of the metal shell, the middle of the spring is arched to form a pressure-bearing part, and the pressure-bearing part protrudes from the outer surface of the metal shell.

[0007] As a preferred technical solution, one end of the assembly groove is open and the other end is sealed. Both sides of the opening of the assembly groove are provided with grooves, and each groove is provided with a limiting plate. One end of each limiting plate extends into the assembly groove and abuts against one end face of the assembly plate. The other end of each limiting plate is equipped with a compression spring, and the other end of each compression spring is installed on the inner wall of the groove. The other end of each assembly plate abuts against the inner wall of the assembly groove.

[0008] As a preferred technical solution, the outer surface of the wear-resistant part is flush with the outer surface of the metal shell.

[0009] As a preferred technical solution, both the assembly plate and the limiting plate are made of metal.

[0010] As a preferred technical solution, all springs are made of metal.

[0011] As a preferred technical solution, a high-temperature resistant coating is provided on the outer surface of the metal shell.

[0012] The beneficial effects of this utility model are as follows: This utility model has a simple structure. One end of the insulating body protrudes to form a wear-resistant part on the outside of the metal shell. When the metal shell is inserted, the wear-resistant part contacts the outside, avoiding damage caused by direct collision between the metal shell and the outside. Furthermore, a spring is installed on the outside of the metal shell. When the metal shell is inserted into the interface, the compression between the spring and the inner wall of the interface increases the stability after insertion. The compression of the spring also reduces the friction between the outer wall of the metal shell and the interface, reducing the probability of wear. The high-temperature resistant coating increases the high-temperature resistance of the metal shell, ensuring its service life. Attached Figure Description

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0018] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a high-temperature and wear-resistant Type-C connector of this utility model includes an insulating body 7 and a metal shell 1 sleeved on the outside of the insulating body 7. One end of the insulating body 7 extends outward from the inside of the metal shell 1 and expands outward to form a wear-resistant part 6. The metal shell 1 has mounting grooves 2 on both sides, and mounting plates 3 are provided inside the mounting grooves 2. Spring pieces 4 are installed on the outer side of the mounting plates 3.

[0020] In this embodiment, the cross-sections of the assembly groove 2 and the assembly plate 3 are both trapezoidal. The outer side of the assembly plate 3 is lower than the outer surface of the metal shell 1. The middle of the spring piece 4 is arched to form a pressure-bearing part, and the pressure-bearing part protrudes from the outer surface of the metal shell 1.

[0021] In this embodiment, one end of the assembly groove 2 is open and the other end is sealed. Both sides of the opening of the assembly groove 2 are provided with grooves, and each groove is provided with a limiting plate 5. One end of each limiting plate 5 extends into the assembly groove 2 and abuts against one end face of the assembly plate 3. The other end of each limiting plate 5 is equipped with a compression spring, and the other end of each compression spring is installed on the inner wall surface of the groove. The other end of each assembly plate 3 abuts against the inner wall surface of the assembly groove 2.

[0022] In this embodiment, the outer surface of the wear-resistant part 6 is flush with the outer surface of the metal shell 1 to avoid affecting the insertion of the metal shell. The length of the metal shell is shortened, but when added with the wear-resistant part, it is the same as the length of the normal metal shell.

[0023] In this embodiment, both the assembly plate 3 and the limiting plate 5 are made of metal, which increases their sturdiness and allows for better positioning.

[0024] In this embodiment, the springs 4 are all metal springs 4, which makes the springs elastic, deformable after being compressed, and the elasticity allows the compressed part to be squeezed with the interface, increasing the stability after insertion.

[0025] In this embodiment, a high-temperature resistant coating is provided on the outer surface of the metal shell 1. The high-temperature resistant coating can be a gold plating layer, a nickel (Ni) plating underlayer + a gold (Au) plating surface layer, or a palladium-cobalt plating layer, which increases the high-temperature resistance of the metal shell.

[0026] During normal insertion, a wear-resistant part is provided at one end of the metal shell. The wear-resistant part is made of rubber material, which is different from the material of the main insulating channel. It is bonded and fixed to the metal shell. The wear-resistant part can block the end of the metal shell, avoiding the wear caused by the end of the metal shell directly colliding with external objects. When the metal shell is inserted into the interface, the arched pressure part in the middle of the spring can squeeze against the inner wall of the interface. The squeezing of the spring reduces the friction between the outer wall of the metal shell and the interface, reducing the probability of wear. Furthermore, the squeezing increases the stability of the metal shell after insertion. When the spring wears out, it can squeeze the limiting plate. After the limiting plate retracts into the groove, the opening of the assembly groove can be in an open state. At this time, the assembly plate can be taken out along the opening of the assembly groove, which facilitates the replacement of the spring. The replacement method ensures the stability of subsequent insertion.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
