[ detailed description ] of the utility model
Embodiment one:
referring to fig. 1-3, the present embodiment is a high-current BTB connector male head 100, which includes a plastic body 1, protective armor 2 embedded in the plastic body 1, and a metal terminal 3.
The plastic body 1 is formed with a plugging slot 11 which is plugged with the connector female seat.
Protective armor 2 is coated on the outer peripheral surfaces of the left and right ends of the plastic body 1. The thickness of the material sheets of the protective armor 2 and the metal terminal 3 is 0.10-0.15 mm, all the electric current can pass through, and the 15A large current can be met, so that the charging efficiency can be effectively improved.
In this embodiment, the protective armor 2 and the metal terminal 3 are formed into an integral structure with the plastic body 1 by Insert molding process, compared with the assembly molding process of the protective armor and the plastic body in the conventional connector, the manufacturing process is simpler, and the connection strength of the protective armor 2 and the plastic body 1 is higher, so that the loosening phenomenon can not occur.
The protective armor 2 is an integrally formed structure and comprises a first sheet 21 covered on the upper surface of the end part of the plastic body 1 and a second sheet 22 which extends downwards from the front side and the rear side of the first sheet 21 and is attached to the front surface and the rear surface of the end part of the plastic body 1. The left or right side of the first sheet 21 is provided with a downward-bent embedded piece 23, and the front and rear sides of the first sheet 21 are provided with downward-bent leg pieces 24.
The embedded sheet 23 and the soldering leg sheet 24 are provided with two end parts along the self-sheet body, wherein one end part is adjacent to the first sheet 21 and exposed on the surface of the plastic body 1 or embedded in the plastic body 1, and the other end part extends out of the surface of the plastic body 1. The embedded piece 23 and the middle part of the welding leg piece 24 are all extended and embedded into the plastic body 1, and the plastic material of the plastic body 1 is used for coating and fixing the embedded piece 23 and the middle part of the welding leg piece 24, so that the stable connection to the position of the protective armor 2 is enhanced, and the strength is improved.
The embedded piece 23 is formed with a connecting portion 231 extending horizontally outward at the end, and the leg piece 24 is formed with a first leg portion 241 extending horizontally outward at the end. The metal terminal 3 is formed with a second soldering leg portion 31 horizontally extending out of the front and rear surfaces of the plastic body 1, and the first soldering leg portion 241 and the second soldering leg portion 31 are flush with the lower surface of the plastic body 1.
