DETAILED DESCRIPTION

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1-6 As shown, this embodiment proposes a connector that is easy to seal, including a male plug 1, a female plug 2, an end shell 3 and a wire 4, one end of the male plug 1 is provided with a female plug 2, one end of the female plug 2 is provided with an end shell 3, one end of the end shell 3 is connected to the wire 4, and a sealing mechanism is provided between the male plug 1 and the female plug 2. Before the male plug 1 is connected to the female plug 2, the sealing mechanism is first installed on the male plug 1, and then the female plug 2 is inserted into the inside of the male plug 1. At this time, the two sides of the sealing mechanism are attached to the male plug 1 and one side of the female plug 2, and the connection between the male plug 1 and the female plug 2 is completely wrapped to ensure the sealing between the male plug 1 and the female plug 2.

[0022] The sealing mechanism includes a sealing shell 5 and a fixing block 6. The male plug 1 and the female plug 2 are both fixed with an assembly plate 16. The fixing blocks 6 are symmetrically fixed on both sides of the assembly plate 16. The sealing shell 5 is clamped between the two groups of the fixing blocks 6. The interior of the fixing block 6 is symmetrically provided with a telescopic rod 8. One end of the telescopic rod 8 is fixedly connected with a clamping block 7. A spring 9 is provided on the outer side of the telescopic rod 8. A group of card slots 10 are symmetrically provided on both sides of the sealing shell 5. The top and bottom ends of the clamping block 7 are slidably connected to the inner wall of the fixing block 6. The length and width of the clamping block 7 are equal to the card slot 10. The two ends of the sealing shell 5 are respectively attached to the assembly plates 16 on the male plug 1 and the female plug 2. The sealing shell 5 is placed on one side of the male plug 1. The outer wall of the sealing shell 5 first squeezes the block 7 to move inside the fixed block 6, and drives the telescopic rod 8 and the spring 9 to be in a compressed state. When the block 7 and the slot 10 are parallel to each other, the elastic force generated by the spring 9 drives the block 7 to enter the slot 10 to snap the sealing shell 5 on one side of the male plug 1. When the female plug 2 is inserted into the male plug 1, it is snapped together with the other side of the sealing shell 5 in the same direction. At this time, the sealing shell 5 wraps the connection between the male plug 1 and the female plug 2 to ensure their sealing. When disassembling, it is only necessary to pull the sealing shell 5 outward to separate it from the male plug 1 or the female plug 2.

[0023] Both ends of the sealing shell 5 are provided with sealing rings 11, the inner wall of the sealing ring 11 is fitted and connected with the outer wall of the male plug 1 and the female plug 2, and the material of the sealing ring 11 is set to be rubber. When the sealing shell 5 and the male plug 1 and the female plug 2 are engaged together, the sealing ring 11 can fill the gap between the sealing shell 5 and the male plug 1 and the female plug 2, so that the sealing performance between the sealing shell 5 and the male plug 1 and the female plug 2 is better.

[0024] One end of the female plug 2 is provided with a plurality of contact posts 14, and the interior of the male plug 1 is provided with a plurality of connection holes 15 matching the contact posts 14. A group of hexagonal prisms 17 with threaded holes are provided on both sides of the assembly plate 16. After the wire on the male plug 1 is connected to the electronic device, the male plug 1 is inserted into the mounting hole of the electronic device. At this time, the screw hole on the hexagonal prism 17 is aligned with the screw hole on the device, and the bolt is screwed into the screw hole to install the male plug 1 on the electronic device. When the contact post 14 is aligned with the position of the connection hole 15, the contact post 14 is inserted into the interior of the connection hole 15. At this time, the male plug 1 and the female plug 2 are connected to each other to transmit current.

[0025] Elastic clips 18 are symmetrically connected to both sides of the assembly plate 16, and an outer shell 13 is provided on one side of the male plug 1 and the female plug 2. Clamping holes 22 are symmetrically provided on both sides of the outer shell 13. The male plug 1 or the female plug 2 is clamped and connected with the clamping holes 22 through the elastic clips 18. The elastic clips 18 are pressed to shrink, and then the outer shell 13 is sleeved on the outside of the male plug 1 or the female plug 2 along the elastic clips 18. When the positions of the elastic clip 18 and the clamping hole 22 are parallel to each other, one end of the elastic clip 18 will pass through the inside of the clamping hole 22 and clamp together with it to fix the outer shell 13 on one side of the male plug 1 or the female plug 2. When disassembly is required, the elastic clip 18 only needs to be pressed into the inside of the clamping hole 22, and the outer shell 13 is pulled out of one side of the male plug 1 or the female plug 2.

[0026] The top and bottom of the outer shell 13 are symmetrically provided with through grooves 19, and the insides of the two through grooves 19 are respectively provided with limit cards 20 and stop blocks 21, and the side adjacent to the limit card 20 and the stop block 21 is provided with a strip groove 12, and the bottom of the limit card 20 is provided with a rectangular groove, and the top of the stop block 21 is engaged with the inner wall of the rectangular groove. The limit card 20 and the stop block 21 are respectively inserted into the top and bottom of the outer shell 13 along the through grooves 19, and the limit card 20 and the strip grooves 12 on the stop block 21 clamp the wires inside the male plug 1 or the female plug 2, and the limit card 20 and the side adjacent to the stop block 21 are engaged with each other to limit the wires inside the male plug 1 or the female plug 2.

[0027] The connector places the sealing shell 5 on one side of the male plug 1. The outer wall of the sealing shell 5 first squeezes the block 7 to move toward the inside of the fixed block 6, and drives the telescopic rod 8 and the spring 9 to be in a compressed state. When the block 7 and the slot 10 are parallel to each other, the elastic force generated by the spring 9 drives the block 7 to enter the slot 10 to engage the sealing shell 5 on one side of the male plug 1. When the female plug 2 is inserted into the male plug 1, it is engaged with the other side of the sealing shell 5 in the same direction. At this time, the sealing shell 5 wraps the connection between the male plug 1 and the female plug 2 to ensure their sealing.
