Each connector includes a housing and multiple terminals respectively disposed within the housing, and a protective sleeve fitted over the housing. A sealing ring is provided at one end of the housing to abut against the protective sleeve. One end of the housing is inserted into the insertion groove of the base, forming a sealing fit between the sealing ring, the insertion groove, and the housing. A wire pass-through hole is provided at the other end of the housing for wire harnesses to pass through. A sealing gasket is provided in the wire pass-through hole, and the sealing gasket is provided with multiple sealing holes for wire harnesses to pass through.
[0006] In some embodiments, the housing is provided with an elastic buckle plate, one end of which has a locking block extending into a slot, and the slot is provided with a locking hole that engages with the locking block.
[0007] In some embodiments, a snap-fit block is provided on one side of the protective sleeve, and a snap-fit hole is provided in the insertion groove to engage with the snap-fit block.
[0008] In some embodiments, a guide protrusion is provided on the other side of the protective sleeve, and a guide slot that engages with the guide protrusion is provided in the insertion groove.
[0009] In some embodiments, multiple sealing protrusions are respectively provided on both sides of the sealing ring to abut against the insertion groove and the rubber shell.
[0010] In some embodiments, the sealing gasket has a plurality of protruding rings that abut against the wire hole.
[0011] In some embodiments, one end of the terminal has a square-shaped insertion frame, a contact spring is provided inside the insertion frame, and a contact protrusion is provided inside the insertion frame at the tail of the contact spring, and an insertion space is formed between the contact protrusion and the contact spring.
[0012] In some embodiments, the tail of the contact spring is provided with an arc-shaped protrusion corresponding to the contact bump.
[0013] In some embodiments, an insertion guide plate is provided on the opening of the plug-in frame corresponding to the tail of the contact spring.
[0014] In some embodiments, the outer wall of the plug-in frame is provided with a positioning boss that engages with the rubber shell.
[0015] The beneficial effects of this utility model are as follows: By adding a sealing ring on the connector housing to seal with the mating groove of the base, rainwater can be prevented from entering the connector and base from the mating groove, thereby improving the sealing performance of the connection between the connector and the base. The sealing gasket can prevent rainwater from entering the connector along the wire harness. The multi-directional sealing structure design provides better waterproof performance.

The terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.
[0024] The directional and positional terms used in this utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.
[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:
[0026] like Figure 1-4 As shown, a multi-port waterproof connector base assembly includes a base 1 and multiple connectors 2 respectively inserted into the base 1. Each connector 2 includes a housing 21 and multiple terminals 22 respectively disposed inside the housing 21 and a protective sleeve 23 sleeved outside the housing 21. A sealing ring 24 is provided on one end of the housing 21 to abut against the protective sleeve 23. One end of the housing 21 is inserted into the insertion groove 11 of the base 1, forming a sealing fit between the sealing ring 24, the insertion groove 11, and the housing 21. The other end of the housing 21 is provided with a wire hole 211 for wire harnesses to pass through. A sealing gasket 25 is provided in the wire hole 211, and a plurality of sealing holes 251 for wire harnesses to pass through are provided on the sealing gasket 25. Adding a sealing ring to the connector housing to seal with the mating groove of the base can prevent rainwater from entering the connector and base from the mating groove, thereby improving the sealing performance at the connection between the connector and the base. The sealing gasket can prevent rainwater from entering the connector from the wire harness. The multi-directional sealing structure design provides better waterproof performance.
[0027] like Figure 1 and 2As shown, the housing 21 is provided with an elastic buckle 212. One end of the elastic buckle 212 has a locking block 213 extending into the insertion groove 11. The insertion groove 11 is provided with a locking hole 12 that engages with the locking block 213. The housing is engaged in the locking hole of the insertion groove by the elastic buckle, which facilitates the assembly of the connector and the base, making assembly more convenient. A snap-fit block 231 is provided on one side of the protective sleeve 23. The insertion groove 11 is provided with a snap-fit hole 13 that engages with the snap-fit block 231. The protective sleeve is engaged in the snap-fit hole of the insertion groove by the snap-fit block, which ensures a tighter and more secure connection between the connector and the base. A guide protrusion 232 is provided on the other side of the protective sleeve 23. The insertion groove 11 is provided with a guide slot 14 that engages with the guide protrusion 232. The guide protrusion serves as a guide, which facilitates the insertion of the connector and the base.
[0028] like Figure 2 As shown, multiple sealing protrusions 241 are respectively provided on both sides of the sealing ring 24, abutting against the insertion groove 11 and the rubber shell 21. The multiple sealing protrusions on the sealing ring elastically deform and tightly fit against the insertion groove and the rubber shell, thereby improving the sealing performance between the rubber shell and the insertion groove. The sealing gasket 25 has multiple protrusions 252 abutting against the wire hole 211. The multiple protrusions of the sealing gasket elastically deform and tightly contact the wire hole, thereby improving the sealing performance of the sealing gasket.
[0029] like Figure 2 , 3 As shown in Figure 5, terminal 22 has a square-shaped insertion frame 221 at one end. A contact spring 222 is disposed within the insertion frame 221, and a contact protrusion 223 is disposed within the insertion frame 221 corresponding to the tail of the contact spring 222. An insertion space 220 is formed between the contact protrusion 223 and the contact spring 222. The terminal adopts a fully enclosed structural design, and the contact spring and contact protrusion are disposed within the insertion frame of the terminal, ensuring a more reliable connection. An arc-shaped protrusion 2221 is disposed at the tail of the contact spring 222 corresponding to the contact protrusion 223. The arc-shaped protrusion increases the contact pressure of the contact spring, ensuring a more reliable connection. An insertion guide 224 is disposed on the opening of the insertion frame 221 corresponding to the tail of the contact spring 222. The insertion guide 224 serves as a guide, thereby helping to reduce the insertion force of the terminal. The outer wall of the connector frame 221 is provided with a positioning boss 2211 that engages with the housing 21. The positioning boss of the connector frame engages with the housing, thereby ensuring a tighter connection between the terminal and the housing.
[0030] Adding a sealing ring to the connector housing to seal with the mating groove of the base can prevent rainwater from entering the connector and base from the mating groove, thereby improving the sealing performance at the connection between the connector and the base. The sealing gasket can prevent rainwater from entering the connector from the wire harness. The multi-directional sealing structure design provides better waterproof performance.
[0031] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
