The beneficial effects of the utility model are:
The utility model is provided with self-locking ports in the rear end of terminal self-locking area, in fixed guide both sides, is provided with self-locking ports, and its effect is that terminal is fixed in sheath, prevents from that terminal from giving up the throne to drop out outside sheath, is convenient to like this crimping of follow-up terminal and wire harness.
The contact area of core crimping district's lead conductor and terminal, electric current and signal transmit between terminal and wire and electrical equipment by this contact area.Also be to guarantee electrical property and the topmost region of mechanical performance simultaneously.
Insulation crimping district is the contact area of wire insulation and terminal, and the effect in this region has 2: 1, prevent that the sheath afterbody that wire insulation retrude causes from having wire core exposed, occur that electric arc connects short circuit phenomenon in high-tension situation; 2, after in insulation crimp region, terminal tails contacts with wrapped in wire, the amplitude of fluctuation between restriction wire and terminal, prevents owing to significantly swinging the possibility of bringing core to be fractureed.
Guider when fixed guide terminal packs sheath into, the Main Function of fixed guide has 2: 1, when terminal packs sheath into, play the guiding role; 2, terminal packs the effect of playing fixed terminal after sheath into, makes terminal in sheath, not rotate or to swing, and guarantees assembling capacity and the stability of terminal and terminal, terminal and sheath.
Before end face both sides, core crimping district are respectively arranged with, protect mouth and rear protection mouthful, front protection mouth and rear protection mouthful are to protect core in core crimping district not to be damaged in cold stamping connection procedure, crimp while preventing core crimping.
Buffering transition region is core crimping district and the region of insulation between crimping district in punching press connection procedure, and Main Function is the region that cold stamping connects the shape strain and stress diffusion causing.Material strip cut-out point terminal is in cold stamping connection procedure, and crimp is by the terminal position separated with material strip.
Accompanying drawing explanation
Fig. 1 is the utility model Wiring harness terminal structural representation.
