The utility model is set to further: on clamping part, the other end of corresponding hangnail is connected with fixed frame, fixed frame is provided with outwardly directed some fixed blocks.
By adopting technique scheme; insulation dust plug is filled in fixed frame; prevent the work entering dust or liquid terminal body in terminal body; by in whole for terminal body insertion end stroma; fixed block will be stuck on terminal base; the rotation of terminal body can be prevented, and then prevent hangnail from being twisted into two parts, protect the safety of hangnail further.
The utility model is set to further: two contact opposite faces are provided with some lug bosses, and outside each contact, the position in respective protrusions portion is provided with some depressed parts.
By adopting technique scheme, depressed part is corresponding with lug boss, only need through the inside punching press of this part of contact can be shaped during production, manufacture craft is simple, edge and the contact body of lug boss and depressed part form rib, contact is not easily opened, plays reinforcement structure function, without the need to thickening contact to strengthen structure, save material.
The utility model is set to further: be provided with line ball portion between the corresponding clamping part of substrate and hangnail, line ball portion comprises the pressure-ray film being symmetricly set on substrate both sides.
By adopting technique scheme, when wire is placed on substrate, stepped up by clamping part, but wire still has part to stretch out clamping part, this part wire will spread out, and by extruding inside the pressure-ray film phase substrate of setting, can be compressed on substrate by stretching out redundance wire, prevent wire front portion from occurring dispersion burr, make wire be combined with substrate further more firm.
The utility model is set to further: there is silver coating on substrate, clamping part and surface, line ball portion.
By adopting technique scheme, make terminal body have good conductivity, the silver metal that other conductivity are good is relatively practical more economically simultaneously.
Compared with prior art, the utility model Anti-falling wiring terminal can prevent hangnail from damaging, and greatly protects the safety of terminal body, strengthens the bonding strength of terminal body and terminal base simultaneously.
