Description

Technical Field

[0001] The utility model relates to the field of terminal blocks, and particularly to a male terminal block. Background Art

[0002] Male terminal blocks are often formed by blanking and bending metal sheets, directly punching and rolling out pins or covering and fixing the pins. Since a spring piece needs to be set during the assembly of the male terminal block to prevent it from falling off the plug, generally, the spring piece is directly formed by outward turning through blanking above it. However, this method will weaken the overall strength and current-carrying cross-section of the terminal, thus greatly affecting the design difficulty, service reliability and lifespan of the male terminal block. Content of the Utility Model

[0011] In the above structure, the covering ear covers the fixing groove on the first side wall through bending to realize the fixation of the shaping ferrule sleeve.

[0012] The present utility model is further configured such that the first bottom wall, the first side wall, and the first top wall of the middle section of the pin segment tightly clamp the pin through stamping.

[0013] In the above structure, an interference fit is presented between the two; or the two are welded together through ultrasonic welding.

[0014] The present utility model is further configured such that the extended end of the pin is provided with a tip.
