[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1: Please refer to Figure 1-5 A small dustproof wire-to-board comprises a main body 1 and a dustproof cover 2 arranged on the main body 1, a wire harness A3 is arranged at the rear side of one side of the main body 1, and a wire harness B4 is arranged at the rear side of one side of the main body 1, and the wire harness A3 and the wire harness B4 are arranged horizontally, and the inner ends of the wire harness A3 and the wire harness B4 are both provided with terminals 5, and TPA6 is arranged at one side of the inner cavity of the main body 1 to limit the terminal 5, and an anti-pull component 7 is installed at one side of the dustproof cover 2.

[0028] The main body 1 is made of plastic.

[0029] The dust cover 2 is closed on three sides to prevent dust from entering the inner cavity of the main body 1 .

[0030] The dust cover 2 is connected to the main body 1 through a dovetail groove and multiple buckles, which play the role of preventing the dust cover 2 from falling off and making it easy to disassemble, as well as fixing the wiring harness A3 and the wiring harness B4.

[0031] The terminal 5 has a material thickness of 0.70 mm and adopts a flat or bent structure design. It is assembled with the wiring harness A and the wiring harness B through an ultrasonic welding process, avoiding the current carrying capacity limitation caused by the crimping process. The stability and current carrying capacity are greatly improved, and the reliability of the connection between the terminal 5 and the cable A3 and the cable B4 is improved.

[0032] Terminal 5 is divided into two pieces, left and right, to which a wire harness A3 or a wire harness B4 can be welded respectively, thereby increasing the current carrying capacity.

[0033] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-3The anti-pull assembly 7 includes an L-shaped plate 71 fixedly mounted on one side of the front and rear sides of the dust cover 2 and a sliding block 72 slidably mounted on the upper and lower sides of the inner side of the L-shaped plate 71. Semicircular card plates A73 are respectively provided on the upper and lower sides of the opposite side of the L-shaped plate 71, and the inner sides of the sliding blocks 72 are respectively fixedly mounted on the adjacent semicircular card plates A73. The front and rear sides of the top of the semicircular card plates A73 are respectively connected with semicircular card plates B75 by bolts 74. The semicircular card plates A73 and the semicircular card plates B75 are respectively clamped on the adjacent wiring harness A3 and wiring harness B 4, rectangular plates 76 are fixedly installed on the inner side of the L-shaped plate 71 near the outer side, and guide rods 77 are slidably installed on the rectangular plate 76 near the upper and lower sides, one end of the guide rod 77 is fixedly installed on the sliding block 72, and springs 78 are respectively sleeved on the outer side of the guide rod 77, and the two ends of the spring 78 are respectively fixedly installed on the sliding block 72 and the rectangular plate 76. The wire harness A3 and the wire harness B4 can be fixed by the semicircular clamping plate A73 and the semicircular clamping plate B75, and the setting of the spring 78 can play a role in pulling and buffering.

[0034] Working principle: When in use, compared with the current carrying capacity of about 50A / PIN of traditional similar wire-to-board solutions, the current carrying capacity of this solution is greatly improved, which can reach 140A / PIN. In addition, the terminal 5 is bent in different directions to achieve the wire outlet in different directions on the left and right sides, which can adapt to more application scenarios. At the same time, by designing multiple barriers, short circuits can be prevented, creepage distances can be increased, and electrical clearances can be increased to achieve high withstand voltage of 2500V and high working voltage of 1570V, ensuring safety in ultra-high voltage environments. The dovetail groove and multiple buckle designs can fix the wiring harness A3 and wiring harness B4 , and prevent the dust cover 2 from detaching from all directions. When connecting, the terminal 5 can be inserted into the plastic and then into the TPA6. The TPA6 limiter prevents the terminal 5 from withdrawing from the main body 1, which is safe and reliable. In addition, the TPA6 is designed with a latch structure to prevent the TPA6 from falling off the main body 1. When in use, the semicircular card plate A73 and the semicircular card plate B75 can be fixed by tightening the bolts 74, so as to fix them on the wire harness A3 and the wire harness B4. When the wire harness A3 and the wire harness B4 are pulled, the spring 78 will play a buffering role to avoid damage caused by pulling.
