[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1 to 4 The electrical connection device with dual sealing function shown includes a base 10 and a cover 20. The base 10 has first sidewalls 11 protruding from all four sides, forming an isolation chamber 17. Circuit boards, connecting lines, and linkage switching structures are all housed within the isolation chamber 17. A second sidewall 12 protrudes from the isolation chamber 17, forming a wiring compartment 18. Metal sleeves or metal inserts are housed within the wiring compartment 18. A first solder wire 13 protrudes from the upper end of the first sidewall 11, and a second solder wire 14 protrudes from the upper end of the second sidewall 12. The cover 20 has third solder wires 21 protruding from all four sides, and within the area enclosed by the third solder wires 21, the cover 20 has protruding ends. The fourth weld wire 22 is connected to the cover 20, which is fitted onto the base 10 during assembly. The first weld wire 13 and the second weld wire 14 are staggered, and the third weld wire 21 and the fourth weld wire 22 are staggered. The first weld wire 13, the second weld wire 14, the third weld wire 21 and the fourth weld wire 22 are welded and fixed by ultrasonic welding. The first weld wire 13 and the second weld wire 14 provide a double seal to prevent water from seeping into the isolation chamber 17 from the outside. The third weld wire 21 and the fourth weld wire 22 also provide a double seal to prevent water from seeping into the isolation chamber 17 from the wiring compartment 18. Compared with the existing design that uses sealing rings and screws for connection and fixation, this application can reduce the number of parts of the electrical connection device, optimize assembly efficiency, and thus reduce production costs.

[0016] In some possible embodiments, a first weld groove 15 is formed on the first side 11 outside the first weld wire 13, and a third weld wire 21 is placed inside the first weld groove 15, that is, after assembly, the third weld wire 21 is located outside the first weld wire 13; a second weld groove 16 is formed on the second side 12 outside the second weld wire 14, and a fourth weld wire 22 is placed inside the second weld groove 16, that is, after assembly, the fourth weld wire 22 is located outside the second weld wire 14; furthermore, the first weld wire 13 is the inner wing of the first weld groove 15, and the second weld wire 14 is the inner wing of the second weld groove 16. During ultrasonic welding, the outer wings of the first weld groove 15 and the outer wings of the second weld groove 16 can both play a positioning role, so that the weld wire is heated and melted to fill the first weld groove 15 / second weld groove 16. For this reason, the outer wings of the first weld groove 15 and the outer wings of the second weld groove 16 are at the same height.

[0017] In some possible embodiments, the gap between the first weld wire 13 and the third weld wire 21 is 'a', where 'a' ranges from 0.5mm to 0.8mm, to allow space for the first weld wire 13 and the third weld wire 21 to melt and fill. The gap between the second weld wire 14 and the fourth weld wire 22 is 'b', where 'b' ranges from 0.5mm to 0.8mm, to allow space for the second weld wire 14 and the fourth weld wire 22 to melt and fill. It should be noted that this gap does not completely disappear after ultrasonic welding. The first weld wire 13 and the third weld wire 21, as well as the second weld wire 14 and the fourth weld wire 22, can be clearly distinguished through this gap. That is, this gap also prevents the first weld wire 13 and the third weld wire 21 from interfering with each other during ultrasonic welding, and prevents the second weld wire 14 and the fourth weld wire 22 from interfering with each other, thereby preserving / achieving the function of double sealing.

[0018] In some possible embodiments, the widths of the first weld line 13, the second weld line 14, the third weld line 21, and the fourth weld line 22 are all in the range of 0.8 mm to 1.0 mm, which ensures that the first weld line 13 / the third weld line 21 is well welded and sealed to the cover 20, and that the second weld line 14 / the fourth weld line 22 is well welded and sealed to the base 10.

[0019] In some possible embodiments, the protrusion heights of the first welding wire 13, the second welding wire 14, the third welding wire 21, and the fourth welding wire 22 are all equal. Furthermore, the first welding wire 13, the second welding wire 14, the third welding wire 21, and the fourth welding wire 22 can be ultrasonically welded simultaneously to improve the ultrasonic welding efficiency and the welding consistency of each welding wire, thereby improving the production yield.

[0020] In some possible embodiments, the interface shapes of the first bonding wire 13, the second bonding wire 14, the third bonding wire 21 and the fourth bonding wire 22 are all triangular or trapezoidal. This design can meet the sealing requirements while reducing the amount of melting of the bonding wires.

[0021] In some possible embodiments, the first bonding wire 13 and the second bonding wire 14 are integrally formed with the base 10, and the third bonding wire 21 and the fourth bonding wire 22 are integrally formed with the cover 20. The base 10 and the cover 20 can both be obtained by injection molding.

[0022] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
