DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] An embodiment of a host waterproof connector of the present invention is as follows Figures 1 to 7 shown.
[0021] A host waterproof connector includes a male connector 100 and a female connector 200. The male connector 100 can move along a first direction toward a side close to the female connector 200 and plug into the female connector 200. The plugging direction of the male connector 100 and the female connector 200 is called the first direction. The male connector 100 includes a first housing 110 and a plurality of male connection ends 120. The plurality of male connection ends 120 are evenly distributed in the first housing 110 around the first direction.
[0022] A flexible sleeve 130 is provided on the male connection end 120, and the flexible sleeve 130 is provided along the first direction close to the side of the female connector 200. The flexible sleeve 130 is made of a deformable flexible material, specifically a rubber material. The female connector 200 includes a second shell 210 and a plurality of female connection ends 220, and the plurality of female connection ends 220 are evenly distributed around the first direction in the second shell 210. The female connection ends 220 are provided in a one-to-one correspondence with the male connection ends 120. A pin 230 is provided on the female connection end 220, and a socket 140 is provided on the male connection end 120. The pin 230 can be plugged into the socket 140.
[0023] The plugging of the male connector 100 and the female connector 200 has a first state and a second state. When in the first state, the flexible sleeve 130 is wrapped around the end of the male connection end 120 and is located between the inner circumferential wall of the female connection end 220 and the outer circumferential wall of the male connection end 120, limiting the contact between the inner circumferential wall of the female connection end 220 and the outer circumferential wall of the male connection end 120; when in the second state, the flexible sleeve 130 is wrapped around the end of the male connection end 120 and is located between the pin 230 and the socket 140, allowing the inner circumferential wall of the female connection end 220 to contact the outer circumferential wall of the male connection end 120.
[0024] In this embodiment, a flexible sleeve 130 is provided on the male connection end 120. Before plugging, the provision of the flexible sleeve 130 can protect the male connection end 120 in the non-plugged state to prevent oxidation of the male connection end 120. When the male connector 100 and the female connector 200 are plugged, in the first plugging state, the flexible sleeve 130 is wrapped 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 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 to avoid 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 the inner peripheral wall surface of the female connection end 220 and the outer peripheral wall surface of the male connection end 120 from being worn. At this time, the flexible sleeve 130 can also clean the impurities that may be attached to the inner peripheral wall surface and the outer peripheral wall surface of the male connection end 120. In the second state of plugging, the flexible sleeve 130 is wrapped around the end of the male connection end 120 and is located between the pin 230 and the socket 140, allowing the inner wall of the female connection end 220 to contact the outer wall of the male connection end 120, and after the male connector 100 and the female connector 200 are plugged in, the connector can be used normally.
[0025] In this embodiment, the female connection end 220 includes a plurality of contact plates 222, which are evenly distributed around the first direction in the second housing 210, and there is a gap between every two adjacent contact plates 222 around the first direction. The contact plates 222 are elastic.
[0026] Further, a sealing strip 223 is disposed between each two contact plates 222 disposed adjacent to each other in the first direction. The sealing strip 223 is located inside the contact plate 222. The sealing strip 223 is elastic and is made of rubber.
[0027] Furthermore, the plurality of sealing strips 223 are connected via sealing rings 224 . The sealing rings 224 are elastic and are made of rubber.
[0028] In this embodiment, a first connection line 111 is disposed inside the first housing 110, and the male connection end 120 is connected to the first connection line 111. A second connection line 213 is disposed inside the second housing 210, and the female connection end 220 is connected to the second connection line 213.
[0029] In this embodiment, the female connection end 220 also includes a connection seat 221, which is connected to the second connection line 213, and a plurality of contact plates 222 are evenly distributed on the connection seat 221 around a first direction. The pin 230 is installed on the connection seat 221 and is coaxially arranged with the connection seat 221, and the pin 230 is located in a space enclosed by the plurality of contact plates 222.
[0030] During the process of the male connection end 120 approaching the female connection end 220 and being plugged into the female connection end 220, the flexible sleeve 130 on the male connection end 120 can expand the contact plate 222 and simultaneously expand the sealing strip 223 and the sealing ring 224. The sealing ring 224 is pressed against the outside of the flexible sleeve 130, and the flexible sleeve 130 contacts the inner circumferential wall of the contact plate 222 to ensure the tightness of the connection.
[0031] In this embodiment, a clamping groove 121 is formed on the male connecting end 120 , and the sealing ring 224 can be clamped with the clamping groove 121 .
[0032] Specifically, the clamping groove 121 is annular and is arranged in the circumferential direction of the male connecting end 120 .
[0033] When the male connection end 120 and the female connection end 220 are plugged in, the sealing ring 224 will be engaged with the slot 121 to improve the connection strength between the male connection end 120 and the female connection end 220 .
[0034] In this embodiment, the first housing 110 is provided with an external thread 112 , the second housing 210 is rotatably provided with a connecting sleeve 211 , the connecting sleeve 211 is provided with an internal thread 212 , and the internal thread 212 is rotatably matched with the external thread 112 .
[0035] Furthermore, a sealing ring 113 is disposed on the first housing 110 , and the sealing ring 113 can abut against an end surface of the second housing 210 .
[0036] In combination with the above embodiments, the specific working process is as follows: When in use, the operator holds the male connector 100 and moves it toward the female connector 200. The initial state of the male connector 120 and the female connector 220 is as shown in FIG. Figure 4 shown.
[0037] During the plugging process, the flexible sleeve 130 on the male connection end 120 can open the contact plate 222, and simultaneously open the sealing strip 223 and the sealing ring 224. The sealing ring 224 is pressed outside the flexible sleeve 130, and the flexible sleeve 130 contacts the inner circumferential wall of the contact plate 222 to ensure the tightness of the connection. Due to the limitation of the flexible sleeve 130, the inner circumferential wall of the female connection end 220 and the outer circumferential wall of the male connection end 120 can be protected to avoid direct contact between the inner circumferential wall of the female connection end 220 and the outer circumferential wall of the male connection end 120, thereby avoiding wear of the inner circumferential wall of the female connection end 220 and the outer circumferential wall of the male connection end 120. At this time, the flexible sleeve 130 can also clean the impurities that may be attached to the inner circumferential wall and the outer circumferential wall of the male connection end 120. See Figure 5 As shown, it is in the first plugged state at this time.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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.
