Description

Technical Field

[0001] This utility model relates to the field of data cable connection technology, and in particular to a water-proof Type-C male connector. Background Technology

[0002] The Type-C interface boasts high data transfer speeds, supports high current flow, and allows for reversible insertion, leading to its increasing adoption in electronic products as the interface for power and data transmission. The Type-C interface combines a male and female connector to enable charging or data transfer. However, existing waterproof structures for Type-C male connectors rely on waterproof components embedded in the housing. This makes the gaps between the contacts and the waterproof components susceptible to liquid ingress, resulting in poor overall sealing and inadequate waterproofing. Even when water is successfully prevented from entering, it can remain inside the male connector for extended periods, affecting its usability. Therefore, there is an urgent need for a Type-C male connector that is both liquid-proof and capable of draining water to address these issues. Summary of the Invention

[0020] Please see Figure 1-5This utility model discloses a water-proof Type-C male connector, comprising a core body 5 and a hook 2, the hook 2 being sealed and penetratingly disposed on the core body 5; it also includes a terminal assembly 6, which is sealed and penetratingly disposed on the core body 5; a PCB board 7, disposed on one side of the core body 5, with one end of the hook 2 and the terminal assembly 6 respectively soldered to the PCB board 7; and a cover body 3, which seals and wraps around the outside of the core body 5, and after wrapping, the entire connector is installed inside a metal housing 1; wherein, the core body 5 includes a waterproof part, which is disposed at the front end of the core body 5 away from the PCB board 7; the core body 5 covers... The device includes an upper half 51 and a lower half 52 that are interconnected. The waterproof part of the upper half 51 includes a waterproof protrusion 511, and the waterproof part of the lower half 52 includes a waterproof groove 521. The waterproof protrusion 511 and the waterproof groove 521 cooperate to seal and form a first path 513 that extends the liquid inflow path. The core body 5 is used to install the hook 2 and the terminal assembly 6, and at the same time to prevent dirt from directly intruding into the PCB board 7 located at the rear end. The covering body 3 is sealed and wrapped around the outside of the core body 5 to protect the core body 5. Then, a metal shell 1 is encapsulated on the outside to complete the encapsulation of the entire male connector.

[0021] Here, to further enhance the waterproofing of the male connector, the core body 5 includes a waterproof section located at the front end of the core body 5 away from the PCB board 7. In this way, the waterproof section can block and protect the liquid at the front end of the core body 5, preventing it from intruding into the rear end. The waterproof protrusion 511 and waterproof groove 521 provided in this application to enhance waterproofing can work together to block and form a first path 513 that extends the liquid inflow path. The waterproof protrusion 511 first blocks the liquid, and if the liquid wants to further intrude, the first path 513 lengthens the passage, thus increasing the difficulty of intrusion and achieving the waterproofing effect.

[0022] In one embodiment, the upper half 51, located at the rear end of the waterproof protrusion 511, further includes a connecting groove 512, and the lower half 52, located at the rear end of the waterproof groove 521, further includes a connecting block 522. The connecting groove 512 and the connecting block 522 cooperate to form a second path 523 that extends the liquid inflow path. The first path 513 and the second path 523 have opposite concave directions. Here, the connecting groove 512 and the connecting block 522 are provided at the rear end to cooperate to ensure a stable connection between the upper half 51 and the lower half 52. Furthermore, the opposite concave directions of the first path 513 and the second path 523 make the core assembly form a three-bend path at this position, which greatly makes it difficult for liquid to penetrate, thereby achieving an excellent waterproof effect.

[0023] In one embodiment, the core body 5, the covering body 3, and the metal shell 1 are all provided with drainage holes 63 on the same side. The multiple drainage holes 63 are interconnected and connected to the side wall of the connecting groove 512. The design of the drainage holes 63 allows the liquid that invades the first path and the second path 523 to avoid staying for a long time and leaving the risk of continued invasion. The invading liquid will be discharged out of the outside of the male head along the drainage holes 63.

[0024] In one embodiment, further, in order to enable the liquid to be discharged more actively, the multiple drain holes 63 each have a flared structure, and the flared structures of the multiple drain holes 63 are connected in sequence to form a large flared structure that is narrow at the connecting groove 512 and wide at the metal shell 1. The flared structure can form an inclined discharge structure, thereby guiding the liquid to flow out from the connecting groove 512 to the outside of the male head.

[0025] In one embodiment, a water-absorbing element 54 is provided near the drain hole 63 in the connecting groove 512. The water-absorbing element 54 extends at least partially into the drain hole 63. The water-absorbing element 54 can further absorb liquid actively, drawing the liquid out of the connecting groove 512 and draining it to the outside of the male connector. Specifically, the water-absorbing element 54 can be absorbent cotton or absorbent cloth. Even if it does not have a drainage effect, it can still absorb the liquid to prevent it from further penetrating the PCB board 7.

[0026] In one embodiment, the terminal assembly 6 includes a plurality of contact terminals 61, at least the middle portion of which is embedded in the core body 5. The middle portion of the contact terminal 61 includes a snap-fit ​​portion 611, which at least partially protrudes from the sidewall of the contact terminal 61. The snap-fit ​​portion 611 increases the locking point and prevents the contact terminal 61 from easily exiting the core body 5.

[0027] In one embodiment, a metal spring 4 is also included, which is installed at the front end of the covering body 3 for engaging with the male connector.

[0028] The advantages of this utility model are: By adding waterproof protrusions and grooves, the liquid can be blocked from entering while the path is extended to make it more difficult for the liquid to further penetrate the PCB board, thus achieving a waterproof effect. Furthermore, a drainage structure is set up to drain the liquid that has already entered the tank.

[0029] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
