Detailed implementation manners

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0026] An embodiment of a waterproof connector for a host computer of the present invention is as follows Figures 1 to 7 shown.

[0027] A waterproof connector for a host computer includes a male head 100 and a female head 200. The male head 100 can move along a first direction towards the side close to the female head 200 and be inserted into the female head 200. The direction in which the male head 100 and the female head 200 are inserted is called the first direction. The male head 100 includes a first housing 110 and a plurality of male connection terminals 120. The plurality of male connection terminals 120 are evenly distributed around the first direction within the first housing 110.

[0028] A flexible sleeve 130 is provided on the male connection terminal 120. The flexible sleeve 130 is arranged on the side close to the female head 200 along the first direction. The flexible sleeve 130 is made of deformable flexible material, specifically rubber material. The female head 200 includes a second housing 210 and a plurality of female connection terminals 220. The plurality of female connection terminals 220 are evenly distributed around the first direction within the second housing 210. The female connection terminals 220 are arranged in one-to-one correspondence with the male connection terminals 120. A pin 230 is provided on the female connection terminal 220, and a jack 140 is provided on the male connection terminal 120. The pin 230 can be inserted into the jack 140.

[0029] The insertion of the male head 100 and the female head 200 has a first state and a second state. When in the first state, the flexible sleeve 130 wraps around the end of the male connection terminal 120 and is located between the inner peripheral wall surface of the female connection terminal 220 and the outer peripheral wall surface of the male connection terminal 120, restricting the contact between the inner peripheral wall surface of the female connection terminal 220 and the outer peripheral wall surface of the male connection terminal 120. When in the second state, the flexible sleeve 130 wraps around the end of the male connection terminal 120 and is located between the pin 230 and the jack 140, allowing the inner peripheral wall surface of the female connection terminal 220 to contact the outer peripheral wall surface of the male connection terminal 120.

[0030] In this embodiment, a flexible sleeve 130 is provided on the male connection end 120. Before insertion, the flexible sleeve 130 can protect the male connection end 120 in the non-inserted state and prevent the male connection end 120 from oxidizing. When the male head 100 and the female head 200 are inserted, in the first state of insertion, the flexible sleeve 130 wraps around the end of the male connection end 120 and is located between the inner peripheral wall surface of the female connection end 220 and the outer peripheral wall surface of the male connection end 120. Due to the restriction of the flexible sleeve 130, it can protect the inner peripheral wall surface of the female connection end 220 and the outer peripheral wall surface of the male connection end 120, avoiding direct contact between the inner peripheral wall surface of the female connection end 220 and the outer peripheral wall surface of the male connection end 120, thereby preventing wear of the inner peripheral wall surface of the female connection end 220 and the outer peripheral wall surface of the male connection end 120. At this time, the flexible sleeve 130 can also clean the impurities that may adhere to the inner peripheral wall surface and the outer peripheral wall surface of the male connection end 120. In the second state of insertion, the flexible sleeve 130 wraps around the end of the male connection end 120 and is located between the pin 230 and the jack 140, allowing the inner peripheral wall surface of the female connection end 220 to contact the outer peripheral wall surface of the male connection end 120. After the insertion of the male head 100 and the female head 200 is completed, it ensures that the connector can be used normally.

[0031] In this embodiment, the female connection end 220 includes a plurality of contact plates 222. The plurality of contact plates 222 are evenly distributed around a first direction in the second housing 210, and there is a gap between every two adjacent contact plates 222 arranged around the first direction. The contact plate 222 has elasticity.

[0032] Further, a sealing strip 223 is provided between every two adjacent contact plates 222 arranged around the first direction. The sealing strip 223 is located inside the contact plate 222. The sealing strip 223 has elasticity, and the sealing strip 223 is made of rubber.

[0033] Furthermore, the plurality of sealing strips 223 are connected by a sealing ring 224. The sealing ring 224 has elasticity, and the sealing ring 224 is made of rubber.

[0034] In this embodiment, a first connecting wire 111 is arranged inside the first housing 110, and the male connection end 120 is connected to the first connecting wire 111. A second connecting wire 213 is arranged inside the second housing 210, and the female connection end 220 is connected to the second connecting wire 213.

[0035] In this embodiment, the female connection end 220 further includes a connection base 221. The connection base 221 is connected to the second connecting wire 213. The plurality of contact plates 222 are evenly distributed around the first direction on the connection base 221. The pin 230 is installed on the connection base 221 and is coaxially arranged with the connection base 221, and the pin 230 is located in the space surrounded by the plurality of contact plates 222.

[0036] During the process that the male connection end 120 approaches the female connection end 220 and is inserted into the female connection end 220, the flexible sleeve 130 on the male connection end 120 can expand the contact plate 222, and synchronously expand the sealing strip 223 and the sealing ring 224. The sealing ring 224 presses against the outside of the flexible sleeve 130, and the flexible sleeve 130 contacts the inner peripheral wall surface of the contact plate 222 to ensure the tightness of the connection.

[0037] In this embodiment, a clamping groove 121 is formed on the male connection end 120, and the sealing ring 224 can be clamped with the clamping groove 121.

[0038] Specifically, the clamping groove 121 is annular and is arranged in the circumferential direction of the male connection end 120.

[0039] When the insertion of the male connection end 120 and the female connection end 220 is completed, the sealing ring 224 will be clamped with the clamping groove 121 to improve the connection strength between the male connection end 120 and the female connection end 220.

[0040] In this embodiment, an external thread 112 is arranged on the first housing 110, a connecting sleeve 211 is rotatably arranged on the second housing 210, and an internal thread 212 is arranged on the connecting sleeve 211. The internal thread 212 is in rotational fit with the external thread 112.

[0041] Furthermore, a sealing ring 113 is arranged on the first housing 110, and the sealing ring 113 can abut against the end face of the second housing 210.

[0042] Combined with the above embodiments, the specific working process is as follows:

[0043] During use, the operator holds the male head 100 and moves it towards the female head 200. In the initial state, the states of the male connection end 120 and the female connection end 220 refer to Figure 4 as shown.

[0044] During the insertion process, the flexible sleeve 130 on the male connection end 120 can expand the contact plate 222, and synchronously expand the sealing strip 223 and the sealing ring 224. The sealing ring 224 presses against the outside of the flexible sleeve 130, and the flexible sleeve 130 contacts the inner peripheral wall surface of the contact plate 222 to ensure the tightness of the connection. Due to the limitation of the flexible sleeve 130, the inner peripheral wall surface of the female connection end 220 and the outer peripheral wall surface of the male connection end 120 can be protected, avoiding direct contact between the inner peripheral wall surface of the female connection end 220 and the outer peripheral wall surface of the male connection end 120. Thus, wear of the inner peripheral wall surface of the female connection end 220 and the outer peripheral wall surface of the male connection end 120 can be avoided. At this time, the flexible sleeve 130 can also clean the impurities that may adhere to the inner peripheral wall surface and the outer peripheral wall surface of the male connection end 120. Refer to Figure 5 as shown, and it is in the first state of insertion at this time.

[0045] As the plugging proceeds, the pin 230 will press against the flexible sleeve 130 and allow the flexible sleeve 130 to enter the plug hole 140 along with the pin 230, and gradually expose the outer peripheral wall of the male connection end 120. When the plugging is completed, see Figure 6 As shown, the sealing ring 224 and the sealing strip 223 will be reset, so that the contact plate 222 is retracted. At this time, it is in the second state of plugging.

[0046] At the same time, the sealing ring 224 is stuck in the slot 121, and the sealing ring 113 on the first housing 110 abuts against the end surface of the second housing 210, and the plugging of the male connector 100 and the female connector 200 is completed. After the plugging is completed, a certain negative pressure will be generated between the sealing strip 223 and the outer surface of the male connecting end 120, thereby further tightening the sealing strip 223 and improving the tightness of the plugging. Then rotate the connecting sleeve 211 to lock the internal thread 212 on the connecting sleeve 211 with the external thread 112 on the first housing 110.

[0047] When the male connector 100 and the female connector 200 need to be unplugged after use, the connecting sleeve 211 only needs to be rotated in the opposite direction, and then one side of the male connector 100 is manually pulled out to disengage the male connector 100 and the female connector 200, and the corresponding flexible sleeve 130 on the male connecting end 120 is manually reset.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
