In order to prevent the sealing plug 300 from being removed from the housing 100 through the first through hole 1022, the first through hole 1022 is a stepped hole, and the outlet 1027 is a small opening end having a diameter smaller than that of the insertion port 1028. Specifically, the wall of the first through hole 1022 is divided into three parts by diameter, i.e., an inner hole section 1024, a first step surface 1025 and an outer hole section 1026, the diameter of the inner hole section 1024 is larger than that of the outer hole section 1026, and the first step surface 1025 is obliquely arranged to limit the sealing plug 300.

The sealing plug 300 is an elastic member, and in this example, rubber is used, but the sealing plug is not limited thereto, and a material suitable for weather resistance and flexibility may be used. As shown in fig. 6, 7 and 12, the outer wall of the sealing plug 300 is shaped to match the hole pattern of the first through hole 1022 and is stepped, and the outer wall of the sealing plug 300 is provided with an inclined second stepped surface 305 which matches the first stepped surface 1025. Meanwhile, the size of the outer wall of the sealing plug 300 is slightly larger than the first through hole 1022, so that the sealing plug 300 is in interference fit with the wall of the first through hole 1022 after being plugged into the first through hole 1022, the sealing performance is improved, and the sealing plug is not easy to fall out after being scattered into the first through hole 1022.

As shown in fig. 4 to 7, the second through hole 301 is also a stepped hole, and the hole type of the stepped hole is matched with the outer wall of the sealing plug 300, so that the sealing plug 300 is shaped like a reducer pipe.

Meanwhile, the fourth hole segment 3032 is connected with the second hole segment 3042 to form a horn shape, the diameter of the first hole segment 3041 is slightly smaller than the diameter of the insertion section 2023 on the terminal 200, the second hole segment 3042 is matched with the shape of the reducing section 2022 and is slightly smaller than the size of the reducing section 2022, and the diameter of the third hole segment 3031 is larger than the diameter of the terminal 200.

When the sealing plug 300 is clamped between the terminal 200 and the housing 100, the outer wall of the sealing plug 300 is in interference fit with the wall of the first through hole 1022, and the two are tightly attached, so that water cannot enter the housing 100 from between the sealing plug 300 and the wall of the first through hole 1022. Meanwhile, the sealing portion 304 is in interference fit with the terminal 200 and is also tightly attached, so that water cannot enter the housing 100 from between the sealing plug 300 and the terminal 200, wherein the first hole section 3041 is tightly attached to the insertion section 2023, and the second hole section 3042 is tightly attached to the diameter-variable section 2022. Meanwhile, the sealing plug 300 is also limited in position by the terminal 200 and the housing 100, i.e., the cord controller has a limiting structure 500, and the limiting structure 500 is divided into two parts, i.e., a first limiting mechanism 501 for limiting the movement to one side of the outer wall of the housing 100 and a second limiting mechanism 502 for limiting the movement to the other side. The first stop mechanism 501 is located between the sealing plug 300 and the first through hole 1022, and the second stop mechanism 502 is located between the sealing plug and the terminal post. The first step surface 1025 in the first through hole 1022 abuts against the second step surface 305 on the outer wall of the sealing plug 300, and serves as a first stopper mechanism 501 for restricting the sealing plug 300 from coming out from the outlet 1026 side of the first through hole 1022. The fourth step surface 203 on the outer wall of the terminal 200 abuts against the second hole section 3042 on the inner wall of the sealing plug 300 to serve as a second limiting mechanism 502 for limiting the sealing plug 300 from coming out from the insertion opening 1028 side of the first through hole 1022. In addition, the sealing plug 300 is further pressed by the second stopper mechanism 502 and the first stopper mechanism 501, and the sealing performance can be improved.

As shown in fig. 4 to fig. 7, a plurality of support ribs 302 are further provided in the sealing plug 300, the support ribs are uniformly arranged at equal intervals along the circumference of the second through hole 301, and the number of the support ribs 302 is ten, but not limited thereto, it is sufficient that all parts of the sealing plug 300 in the circumference are uniformly supported. The support ribs 302 extend in the radial direction of the second through hole 301, and each support rib 302 extends from one end of the third bore segment 3031 far from the sealing portion 304 to one end of the fourth bore segment 3032 close to the sealing portion 304, i.e., the support portion 303 is distributed over the second through hole 301 in the axial direction. In addition, one end of the support rib 302 has a guide face 3021, the guide face 3021 is an inclined plane which is located at one end of the support rib 302 away from the support portion, the terminal 200 is preferentially abutted against the guide face 3021 when mounted, and the guide face 3021 guides the insertion of the terminal 200 into the second through hole 301. The supporting portion 303 is in interference fit with the terminal 200, and the terminal 200 can enlarge the outer contour of the portion of the sealing plug 300 with the supporting rib 302 by the supporting portion 303 due to the elasticity of the sealing plug 300, so that the portion of the outer wall of the sealing plug 300 corresponding to the supporting portion 303 can be tightly attached to the wall of the first through hole 1022. Simultaneously, this supporting part 303 passes through brace 302 butt terminal 200, and only brace 302 contacts terminal 200, reduces the area of contact of supporting part 303 for the terminal is by resistance is littleer when passing through supporting part 303, and operating personnel application of force is littleer, the installation of being convenient for.

In mounting the line controller, the mounting of the terminal 200 and the circuit board 400, that is, the soldering of the terminal 200 to the circuit board 400 and the fixing of the circuit board 400 to the bottom cover 101, may be previously performed. Subsequently, the sealing plug 300 is correspondingly inserted into the first through hole 1022, and the sealing ring 103 is fitted over the limiting rib 1021. Finally, the terminals 200 correspond to the first through holes 1022, and the positioning protrusions correspond to the positioning holes, so that the front cover 102 and the rear cover 101 are combined into a whole.

In some exemplary embodiments, the limiting structure 500 comprises only the first limiting mechanism 501, or only the second limiting mechanism 501, and only one-way limits the sealing plug 300.

With the above embodiment, the sealing plug 300 is in interference fit with the first through hole 1022 and is in interference fit with the terminal 200, so that water is prevented from entering the housing 100 from the gap between the sealing plug 300 and the housing 100 and the gap between the sealing plug 300 and the terminal 200, and a good seal is achieved. Meanwhile, the contact area can be reduced due to the arrangement of the support rib 302, so that the resistance of the wiring terminal 200 to be plugged into the second through hole 301 is reduced, and the installation is facilitated. In addition, the stopper 500 and the support rib 302 can further improve the sealing effect by increasing the deformation of the sealing plug 300.
