In subsequent use, it is connected to both ends of the outer sealing strip 4. Through the snap-fit with the car door and mutual limiting, the stability and accuracy of the car door outer waterproofing assembly on the car door are ensured.
[0040] In addition, the mounting connector 1 described in this invention includes a positioning insert 2; the positioning insert 2 is mainly a connector, which not only facilitates the installation of the mounting connector 1 in the outer sealing strip 4, but also facilitates the snap-fit installation of the end area of the outer waterproof assembly of the car door on the upper sheet metal of the outer door panel 5 during subsequent use.
[0041] In this invention, the positioning insert 2 includes a secondary positioning rib 21 and a primary positioning rib 22; the secondary positioning rib 21 and the primary positioning rib 22 are connected to each other at the ends near the roof and are spaced apart at the ends away from the roof; an assembly gap is formed between the secondary positioning rib 21 and the primary positioning rib 22; based on the above design, the vertical cross section of the positioning insert 2 disclosed in this invention is an inverted V-shape or an inverted U-shape structure. This arrangement facilitates the secondary positioning rib 21 and the primary positioning rib 22 to be snapped onto the snap-fit flange 52 on the outer panel 5 of the door during subsequent use.
[0042] In addition, in this invention, the secondary positioning rib 21 and the main positioning rib 22 are arranged in an intersecting manner. This arrangement facilitates the realization of a structure in which the secondary positioning rib 21 and the main positioning rib 22 are connected at one end and extend freely at the other end.
[0043] Furthermore, in this invention, the main positioning rib 22 includes a main rib plate 221, which is a part of the main positioning rib 22. In this invention, the main rib plate 221 is provided with a snap-fit mechanism. The snap-fit mechanism is mainly provided to facilitate subsequent installation and use, so as to snap-fit with the snap-fit flange 52 and the slot 53 on it, thereby realizing the installation and fixing of the installation joint 1 on the outer panel 5 of the door; at the same time, it can also realize the Z-direction limiting of the installation joint 1, and finally realize the Z-direction limiting of the outer waterproof assembly of the door.
[0044] In this invention, the snap-fit mechanism includes a clearance groove 227 disposed on the main stiffener plate 221; the clearance groove 227 is provided with a first protruding snap rib 225, the clearance groove 227 is equivalent to opening a through groove on the main stiffener plate 221, and the first protruding snap rib 225 is equivalent to one end being connected to the inner wall of the clearance groove 227 and the other end extending freely, and the first protruding snap rib 225 is provided with a first snap rib flange 226; the first snap rib flange 226 is arranged on the side of the first protruding snap rib 225 near the secondary positioning rib 21, and the first snap rib flange 226 can be set perpendicular to the first protruding snap rib 225; this arrangement makes the first snap rib flange 226 and the first protruding snap rib 225 form a barbed structure, which is essentially a snap-fit structure, making it convenient to be hooked into the snap groove 53 on the snap-fit flange 52 later.
[0045] Furthermore, in this invention, the main stiffening plate 221 is also provided with a limiting rib 224; the limiting rib 224 is located on the side of the main stiffening plate 221 away from the secondary positioning rib 21; the limiting rib 224 is set at the end of the main stiffening plate 221 close to the main positioning rib 22 and the secondary positioning rib 21; the limiting rib 224 mainly plays a limiting role, and subsequently presses against the end of the outer sealing strip 4, playing a good positioning and limiting role, preventing the positioning insert from rotating around the outer sealing strip 4, which would affect the stability of the installation joint 1 embedded in the outer sealing strip 4.
[0046] In this invention, the limiting rib 224 is equivalent to a protrusion provided on the main rib plate 221; when the installation joint 1 is subsequently embedded in the outer sealing strip 4, the upper end of the limiting protrusion presses against the end of the outer sealing strip 4, thereby playing a good relative limiting role.

[0048] In addition, the limiting component in this invention includes two spaced-apart limiting ribs 222; the two limiting ribs 222 are spaced apart, and a positioning notch 223 is formed between the two limiting ribs 222; in this invention, the limiting ribs 222 also play a good role in fitting and limiting, and in subsequent use, they also cooperate with the secondary positioning ribs 21 to fit on both sides of the outer door panel 5 to ensure the contact area between the mounting joint 1 and the outer door panel 5.
[0049] In addition, in this invention, the main stiffening plate 221 and the limiting stiffening plate 222 are essentially distributed on the same plane. Of course, in actual production design, it is also feasible to have a certain deviation; the specific design can be carried out as needed.
[0050] In addition, in this invention, the limiting rib plate 222 and the main rib plate 221 in the limiting component can be distributed at intervals, or the limiting rib plate 222 and the main rib plate 221 on the side closer to the main rib plate 221 can be attached to each other.
[0051] Furthermore, the mounting connector 1 in this invention also includes an end cap 3, which is located at the end of the positioning insert 2. In this invention, the positioning insert 2 is embedded in the outer sealing strip 4.
