According to the utility model, the connection mode of the wiring terminal and the PVC wire is changed, two puncture teeth and the U-shaped puncture hole formed between the two puncture teeth are designed, in the process of pressing the PVC wire and the wiring terminal, the two puncture teeth penetrate into the PVC wire and are electrically connected with the metal wire in the PVC wire, and then the U-shaped puncture hole is clamped with the PVC wire, so that the electric connection of the wiring terminal and the PVC wire is completed.

Description

Puncture type wiring terminal

Technical Field

The utility model relates to the technical field of electronic devices, in particular to a puncture type wiring terminal.

Background

Binding post is the part commonly used among the circuit connection, need peel off the PVC insulating layer of PVC line when current binding post is connected with the PVC line, then welded connection again, this mode welding point is easy to be oxidized, and the installation too operates complicacy, has reduced binding post's safety in utilization, has reduced binding post's installation effectiveness.

Therefore, how to provide a terminal that is not easily oxidized, is easy and convenient to install, and has good electrical conductivity is a technical problem that needs to be solved by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model provides a puncture type wiring terminal, which solves the technical problems that the installation process of the existing wiring terminal is too complicated and a welding point is easy to oxidize and rust.

The technical scheme for solving the technical problems is as follows: a puncture-type wiring terminal is installed in a switch box and comprises: the front end surface of the mounting block is recessed towards the rear side of the mounting block to form a mounting groove penetrating through the end surfaces of the two sides of the mounting block; the piercing tooth assembly comprises two piercing teeth which are of right-angled triangle structures, the right-angled sides of one sides of the two piercing teeth are vertically fixed at the bottom of the mounting groove, the right-angled sides of the other sides of the two piercing teeth are oppositely arranged at intervals and form a U-shaped piercing opening between the right-angled sides, and the width of the U-shaped piercing opening is the same as the diameter of a metal wire of a PVC wire.

The utility model has the beneficial effects that: the connection mode of the wiring terminal and the PVC wire is changed, two puncture teeth and a U-shaped puncture hole formed between the two puncture teeth are designed, in the pressing process of the PVC wire and the wiring terminal, the two puncture teeth penetrate into the interior of the PVC wire and are electrically connected with the metal wire in the PVC wire, and then the U-shaped puncture hole is connected with the PVC wire in a clamping mode, so that the electric connection of the wiring terminal and the PVC wire is completed, and the electric connection mode is simple in installation and operation, free of spray welding, easy to replace and good in electrifying performance.

On the basis of the technical scheme, the utility model can be further improved as follows.

Further, the plurality of the puncture tooth assemblies are arranged in parallel and at intervals.

Furthermore, the switch box also comprises a fixing piece which is fixed on one side surface of the mounting block and used for fixing the mounting block in the switch box.

Further, the mounting block, the two piercing teeth and the fixing piece are all of an integrally formed structure.

The adoption of the further beneficial effects is as follows: the stability of binding post structure can be improved to integrated into one piece.

Further, the mounting block, the two piercing teeth and the fixing piece are all made of metal materials.
