Description

A kind of plug lead wiring terminal

Technical field

The utility model relates to a kind of wire connection device, relates in particular to a kind of plug lead wiring terminal, and the stripped end of lead can be inserted in this electric wire connecting junction, connects thereby form conduction between lead.

Background technology

Conflux for realizing each copper conductor conduction each other, someone designs a kind of binding post, it is with the lead patchhole of the many interconnective leads insertion of needs binding posts, and lead is promptly clamped by the binding clip in the terminal, and forms the conduction connection between lead.

As a patent No. is a kind of structure the Chinese invention patent " wire jointing clamp " of ZL97123011.0 (notification number is CN1096722C) has disclosed, include the insulating material shell, insert the Metal Contact plug-in unit that has at least two clamp positions in the shell, each clamp position forms between a slice spring and a bus shared for all clamp positions, the sheet spring is a ligule, form by a steel spring plate punching out, the root of each ligule sheet spring keeps connecting through steel spring plate each other, each is become free ligule sheet spring termination towards part that one clamp seamed edge is respectively arranged by punching out, opposed with bus, thereby each forms a clamp position with bus, be used for clamping interconnective electric wire, it is characterized in that, the per two sheet springs that formed by the punching out of steel spring plate member are symmetrical in mid-plane with being mirror surface type, its ligule termination each interval certain distance, and the steel spring plate material between the ligule sheet spring termination is washed open and is formed a freedom towards part, bus is the bar shape, is arranged in free on part and on the mid-plane.

The advantage of said wires binding clip is with spring steel of trying one's best few and the clavate bus combination of trying one's best few, carries out the connection of conductor wire.

1., that conductor wire and female rod intersect contact point is little but there is following shortcoming in it:, current delivery resistance is big, is unfavorable for the current delivery of multipole lead, in the time of in lead inserts this binding clip, is easy to generate spark, uses dangerous; 2., tongue is gone out from steel plate simply, and tongue edge and steel plate inner edge are very close to each other, and adopt punching process easily to produce burr at the stamping-out edge, in tongue when action, is because the existence of burr, it is sick that tongue edge and steel plate have card to roll dirt, when tongue edge and steel plate have card to roll the elastic force that can not guarantee tongue; 3., the root of tongue do not have the R angle, can not give full play to the resiliency characteristics of spring steel, pressure is small and weak, lead tightly can not be clamped.
