However, existing connectors for USB, HDMI, and Type-C interfaces lack external waterproofing. During connection, the connector directly plugs into the interface. If water is accidentally spilled on the connector, it can seep into the connector, potentially damaging the connector or the electronic / audio equipment. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides a connector, comprising a connector body, a protective shell, and a tail sleeve. The connector body is externally injection molded with an elastic layer. A cable is provided at the tail end of the connector body. A slot is formed inside the protective shell. The elastic layer is inserted into the slot and interference-fits the slot. The connector body does not protrude from the protective shell. The front end of the protective shell is adapted for connection to electronic or audio equipment. The side of the protective shell near the front end of the connector body is open to allow the connector body to mate with an interface. The tail sleeve is located on the side of the protective shell near the cable. The tail sleeve is connected to the protective shell to seal the tail end of the protective shell. The tail sleeve is fitted onto the cable and interference-fits the cable.

[0004] Optionally, the connector body is a USB connector, an HDMI connector, or a Type-C connector.

[0005] Optionally, the protective housing has a partition inside, which divides the interior of the protective housing into a first chamber and a second chamber. The second chamber is located on the side of the partition near the front end of the protective housing, and the side of the second chamber away from the partition penetrates the protective housing. The slot is provided on the partition and penetrates the partition. The end of the connector body away from the cable passes through the slot and is located in the second chamber.

[0006] Optionally, the protective shell extends through the side of the first chamber away from the partition, the connector body is inserted into the slot within the first chamber, the outer wall of the elastic layer is provided with an elastic protrusion, the partition is provided with a mating groove on the side near the first chamber, the mating groove is interconnected with the slot, and the elastic protrusion is interference-fitted into the mating groove.

[0007] Optionally, the mating groove does not penetrate the partition along the direction in which the connector body is inserted into the slot.

[0008] Optionally, the groove wall of the mating groove is provided with a pressing slope, which is adapted to drive the elastic protrusion to fit tightly with the mating groove.

[0009] Optionally, one end of the tail sleeve is inserted into the first cavity and threadedly connected to the protective outer shell.

[0010] Optionally, a sealing ring is fitted onto the tail sleeve, and a compression part is provided on the outer wall of the tail sleeve. The compression part is located on the side of the sealing ring away from the protective shell, and the two sides of the sealing ring abut against the compression part and the tail end of the protective shell, respectively.

[0011] Optionally, a sealing ring is provided in the second chamber, the sealing ring abuts against the partition, the front end of the connector body is located inside the sealing ring, the sealing ring is adapted to abut against the end of the mating interface to form a seal, and the outer wall of the sealing ring is provided with a ring groove.

[0012] Optionally, the second chamber has a sealing groove on its wall, and the outer peripheral wall of the sealing ring is located within the sealing groove.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] 1. The entire connector body is located inside the protective shell, and the front end of the protective shell will be plugged into the interface of the electronic device or audio device, so that the connector body can be protected by being covered, which improves the waterproof performance of the connector. The connector body is plugged into the protective shell, which improves the convenience of assembly.

[0015] 2. After the cable passes through the tail sleeve, the interference fit between the cable and the tail sleeve, along with the sealing ring, forms a double seal, making it difficult for water to seep into the first chamber. This improves the sealing and waterproof performance of the connector. At the same time, the interference fit between the elastic layer and the slot improves the airtightness between the first and second chambers. Even if water seeps into the first chamber, it is not easy to enter the second chamber and affect the front end of the connector body. An additional seal is added to further improve the sealing and waterproof performance of the connector.

[0016] 3. After the protective shell is plugged into the interface of the electronic device or audio device, the end of the interface will squeeze the sealing ring. Under the action of the ring groove, the sealing ring is more likely to deform after being squeezed, so as to play a sealing role. When the connector is connected, water is not easy to enter from the front of the protective shell and affect the connector body, thus improving the sealing performance of the front end of the connector after mating.

[0017] 4. After the sealing ring is placed into the second chamber, the outer peripheral wall of the sealing ring will be stuck into the sealing groove, making it difficult for the sealing ring to fall out of the second chamber and improving the stability of the sealing ring after installation.

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] This utility model provides a connector connector, see reference. Figure 1 The connector includes a connector body 1, a protective housing 2, and a tail sleeve 3. One end of the connector body 1 is electrically connected to a cable 11, and this end is designated as the tail end. Correspondingly, the end of the protective housing 2 closest to the cable 11 is also designated as the tail end. The connector body 1 is interference-fitted into the protective housing 2 and does not protrude from it. The tail sleeve 3 is located at the tail end of the protective housing 2 and connects to it to seal the tail end. The tail sleeve 3 is fitted onto the cable 11 and interference-fitted with it. The connector body 1, protective housing 2, and tail sleeve 3 form a multi-layered sealing structure, thereby improving the connector's sealing and waterproof properties.

[0031] Combination Figure 1 Reference Figure 2 and Figure 3 The connector body 1 can be a USB connector, an HDMI connector, or a Type-C connector. In this embodiment, it is preferred that the connector body 1 can be a USB connector.

[0032] Reference Figure 4 and Figure 5 The protective shell 2 has an integrally formed partition 21 inside, which divides the interior of the protective shell 2 into a first chamber 22 and a second chamber 23. The first chamber 22 is located on the side of the partition 21 near the rear end of the protective shell 2, and the corresponding second chamber 23 is located on the side of the partition 21 near the front end of the protective shell 2. The side of the first chamber 22 away from the partition 21 penetrates the protective shell 2; similarly, the side of the second chamber 23 away from the partition 21 also penetrates the protective shell 2, making the protective shell 2 a shell with openings at both ends.

[0033] Combination Figure 4 Reference Figure 5 and Figure 6 In one embodiment, the front end of the connector body 1 is inserted into the partition 21 from the rear end of the protective shell 2. In another embodiment, the rear end of the connector body 1 can be inserted into the partition 21 from the front end of the protective shell 2. A slot 24 is provided on the side of the partition 21 near the first chamber 22. The slot 24 penetrates the partition 21 so that the first chamber 22 and the second chamber 23 are interconnected.

[0034] The connector body 1 is externally encased in an elastic layer 12, which has a certain elastic deformation capability. The elastic layer 12 is inserted into the slot 24, improving ease of assembly. The front end of the connector body 1 passes through the slot 24 and is located in the second chamber 23 to interface with the interface on electronic or audio equipment. The rear end of the connector body 1 is located in the first chamber 22. The elastic layer 12 and the slot 24 have an interference fit, improving the airtightness between the first chamber 22 and the second chamber 23. Water that seeps into the first chamber 22 is less likely to enter the second chamber 23 and affect the front end of the connector body 1.

[0035] Combination Figure 4 Reference Figure 5 and Figure 6 The elastic layer 12 has elastic protrusions 13 integrally formed on both sides of its outer wall. The partition 21, near the first chamber 22, has mating grooves 25 corresponding to the number of elastic protrusions 13. These grooves 25 communicate with the slots 24. The elastic protrusions 13 are inserted into the mating grooves 25 to provide positioning for the connector body 1 during insertion. The mating grooves 25 do not penetrate the partition 21 along the direction in which the connector body 1 is inserted into the slot 24. Therefore, the cooperation between the elastic protrusions 13 and the mating grooves 25 provides a limiting effect for the installation of the connector body 1, ensuring the installation accuracy of each connector body 1 and allowing each connector body 1 to be properly inserted during assembly.

[0036] The groove wall of the mating groove 25 is provided with a pressing slope 26, which gradually extends towards the center of the mating groove along the insertion direction of the connector body 1. As the elastic protrusion 13 penetrates deeper into the mating groove 25, the elastic protrusion 13 will be deformed by the pressing slope 26 and fit tightly with the mating groove 25, thereby causing the elastic protrusion 13 to form an interference fit with the mating groove to form a seal, so that water in the first chamber 22 is not easy to seep into the second chamber 23 from between the elastic protrusion 13 and the mating groove.

[0037] Combination Figure 4 Reference Figure 5 and Figure 6 The end of the tail sleeve 3 near the protective housing 2 is inserted into the first chamber 22 and threadedly connected to the protective housing 2. The end of the tail sleeve 3 near the protective housing 2 has a through hole for the cable 11 to pass through. The size of the through hole is smaller than the outer diameter of the cable 11. Since the cable sheath of the cable 11 has a certain elastic deformation capability, the tail sleeve 3 and the cable 11 are interference-fitted, making it difficult for external water to enter the first chamber 22 through the through hole.

[0038] Reference Figure 7In another embodiment, the protective shell 2 is a metal shell, and the connector body 1 is inserted into the protective shell 2 and then a tail sleeve 3 is formed by secondary injection molding. This makes the connection between the tail sleeve 3 and the protective shell 2 more secure and the connection between the tail sleeve 3 and the protective shell 2 more airtight.

[0039] Combination Figure 4 Reference Figure 5 and Figure 6 A sealing ring 31 is fitted onto the tail sleeve 3. The sealing ring 31 is made of elastic material and will deform when compressed. A compression part 32 is provided on the outer wall of the tail sleeve 3. The compression part 32 is located on the side of the sealing ring 31 away from the protective shell 2, and the outer diameter of the compression part 32 is larger than the inner diameter of the sealing ring 31. When the tail sleeve 3 is twisted to move it closer to the protective shell 2, the compression part 32 and the tail end of the protective shell 2 will compress the sealing ring 31, causing it to deform and achieve a sealing effect, thereby preventing water from seeping into the first chamber 22 from the connection between the tail sleeve 3 and the protective shell 2.

[0040] Combination Figure 4 Reference Figure 5 and Figure 6 The second chamber 23 contains a sealing ring 27, which abuts against the partition 21. The front end of the connector body 1 is located inside the sealing ring 27. After the front end of the protective shell 2 is inserted into the electronic device or audio device, the corresponding interface will be inserted into the second chamber 23 and mat with the connector body 1. At this time, the end of the interface will press against the sealing ring 27 to form a seal. When the connector is connected, water is less likely to enter from the front end of the protective shell 2 and affect the connector body 1, thus improving the sealing performance of the front end of the connector after mating.

[0041] The outer wall of the sealing ring 27 is provided with a ring groove 28. The ring groove 28 provides room for deformation of the sealing ring 27 when it is compressed, making it easier to deform and produce a better sealing effect. In addition, a sealing groove 29 is provided on the cavity wall of the second chamber 23. The outer peripheral wall of the sealing ring 27 is located in the sealing groove 29, making it less likely for the sealing ring 27 to fall out of the second chamber 23 during daily use.

[0042] The implementation principle of a connector in this application embodiment is as follows: when the connector is connected to an electronic device or audio device, the front end of the protective shell 2 is inserted into the female socket of the device, and the corresponding interface on the female socket is inserted into the second chamber 23 and docks with the front end of the connector body 1.

[0043] First, the entire connector body 1 is located inside the protective shell 2, so that the connector body 1 can be sleeved and protected.

[0044] Secondly, after the cable 11 passes through the tail sleeve 3, it is press-fitted with the tail sleeve 3; the extrusion part 32 and the tail end of the protective shell 2 press against the sealing ring 31 to achieve a sealing effect; the elastic layer 12 and the slot 24 are press-fitted together to form a triple sealing structure, which improves the airtightness and waterproof performance of the connector joint.

[0045] Finally, after the front end of the protective shell 2 is plugged into the interface on the electronic or audio equipment, the end of the interface will compress the sealing ring 27. Under the action of the annular groove 28, the sealing ring 27 is more likely to deform after being compressed, thus playing a sealing role. When the connector is connected, water is less likely to enter from the front end of the protective shell 2 and affect the connector body 1, improving the sealing performance of the front end of the connector after mating. This results in better airtightness and waterproof performance of the entire connector.

[0046] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
