By arranging the insulating layer 24 on the surface of the fixing portion 22, moisture is prevented from permeating into the insulating body 1 and corroding the fixing portion 22 in the insulating body 1.
In the embodiment, the insulating layer 24 may be formed by coating insulating paint on the surface of the metal terminal 2, or by performing physical vapor deposition on the surface of the metal terminal 2, and spraying UV glue before forming the insulating layer by using the physical vapor deposition to better shape the insulating layer.
The insulating body 1 includes a base 11 and a sidewall 12 extending perpendicularly from the base 11. The fixing portion 22 of the metal terminal 2 is fixed to the base portion 11, and one side of the contact portion 21 is buried in the side wall 12 and also an insulating layer 24 is formed on the surface thereof. The insulating body 1 further comprises a partition 13 connecting the side wall 12 with the base 11, the partition extending in a vertical direction without exceeding the side wall 12. The metal terminals 2 are all in the shape of a sheet. The insulating body 1 extends backward from the base 11 thereof to form a mounting cavity 111, and the pin portion 23 extends backward to be exposed in the mounting cavity 111 without exceeding.
The contact portion 21 includes a transition region 211 adjacent to the insulator 1 and a contact region 212 continuously extending from the transition region 211. The transition region 211 also has an insulating layer 24 formed on its surface. The contact portion 21 includes a first transition region 213 adjacent to the base portion 11 and a second transition region 214 adjacent to the sidewall, wherein the first and second transition regions 213 and 214 have an insulating layer 24 formed on the surface thereof. Referring to fig. 5, the insulating layer 24 covers the non-conductive area of the metal terminal 2 as much as possible, thereby reducing corrosion and prolonging the service life. Meanwhile, the metal terminal 2 in this embodiment is inserted into a corresponding terminal groove provided in the insulating body 1.
The plurality of metal terminals 2 include a power terminal 25, a first signal terminal 26 and a second signal terminal 27, the power terminal 25 is arranged along a first direction, the first and second signal terminals 26, 27 are arranged and aligned along a second direction, the first and second signal terminals 26, 27 are parallel to the power terminal 25, and the first direction and the second direction are perpendicular to each other; in the vertical direction, the first signal terminals 26 are shorter than the second signal terminals 27. One side of the contact portion between the power supply terminal 25 and the second signal terminal 27 is embedded in the side wall 12, and the first signal terminal 26 is distant from the side wall 12. The power terminal 25 has two spaced-apart pin portions 23 and the first and second signal terminals 26, 27 have a single pin portion 23.
As shown in fig. 3, the contact portion 21 of the power terminal 25 includes a transition portion 251 adjacent to the base 11, and the transition portion 251 of the power terminal 25 has an area adjacent to the sidewall 12 larger than an area of a portion away from the sidewall 12. The contact portions 21 of the first and second signal terminals 26 and 27 include transition portions 261 and 271 adjacent to the base portion 11, and the top end of the transition portion 271 of the second signal terminal 27 is higher than the top end of the first signal terminal 26.
