The cassette design has pressure arm A, pressure arm B, and the head of pressure arm has the dogtooth, and pressure arm A and pressure arm B are eight characters type, when the power cord drew toward the plug is inside, pressure arm A, pressure arm B opened to a pressure arm fender department backward, when the power cord toward the plug outside when drawing pressure arm A, pressure arm B fold forward and sting tight power cord. The trench is participated in in the design on the base, the design presser foot is covered to the face, and the face lid of closing, presser foot can directly compress tightly the wire installed on the wiring groove and the package wall of wire, multiplicable area of contact and tensile frictional force, the tensile strength of improvement plug.

Description

A kind of new type of plug

Technical field

The utility model relates to a kind of new type of plug.Especially home-use or work plug, realization copper sheet cuts open power supply bag wall, makes the reliable connection of conductive component, and this structure production efficiency is high, and product cost is low, has good lifting useful life.

Background technology

Present stage, the wiring of general power-line plug, need first strip off head of line packet wall that core is exposed, then screw down and compress core link, when screw torsion is not enough, core easily gets loose, screw torsion is excessive easily twists off barish core again, and reduce electric conductivity, therefore this kind of installation method can not pass through tensile test.In order to by tensile test, must increase compressing structure in addition again at bus place, just compress enough frictional force by tensile test together with bag wall, the complex process done like this, production efficiency is low.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel plug construction.A kind of new type of plug, is made up of cover (1), pin (2), deck (3), base (4), screw (5), presser feet (1-1), the edge of a knife (2-1), connecting groove (2-2), positioning boss (2-3), pressure arm A (3-1), pressure arm B (3-2), double wedge (3-3), pressure arm gear (4-1), pin slot (4-2); It is characterized in that: only need each stock wire is pressed in connecting groove (2-2) respectively through the edge of a knife (2-1) of pin (2) during installation, again bus is drawn from deck (3), close cover (1), then uses the fixing cover (1) of screw (5) and base (4) namely to complete installation.Pin (2) is designed with the edge of a knife (2-1), connecting groove (2-2), first enter in connecting groove (2-2) again through the edge of a knife (2-1) when wire press-in connecting groove (2-2), the edge of a knife (2-1) is sharp copper sheet, the bag wall of wire can be cut open and make it be stuck on connecting groove (2-2), the core of wire can contact with connecting groove (2-2) and conduct electricity.Deck (3) is plastic cement material; Deck (3) is designed with pressure arm A (3-1), pressure arm B (3-2), and the head of pressure arm is with double wedge (3-3), and pressure arm A (3-1) and pressure arm B (3-2) is in splayed configuration; When power line draws toward plug inside, pressure arm A (3-1), pressure arm B (3-2) open to pressure arm gear (4-1) place backward, make power line can draw in wiring smoothly; When power line draws toward plug exterior, pressure arm A (3-1), pressure arm B (3-2) close up forward and sting tight power line, and power line is not drawn out.Base (4) is designed with pin slot (4-2), the geomery of pin slot (4-2) and matching of pin (2); Pin (2) is designed with positioning boss (2-3), when the pin of pin (2) inserted base (4) joins slot (4-2), pin (2) is stuck on base (4) by positioning boss (2-3), and pin (2) is not got loose.Cover (1) designs presser feet (1-1), the geomery of presser feet (1-1) and the connecting groove (2-2) of pin (2) match, close cover (1), presser feet (1-1) directly can compress the bag wall of wire and the wire be arranged on connecting groove (2-2), contact area and tension frictional force can be increased, improve the tensile property of plug.Basis is practical is applicable to triangle plug, is also applicable to two jiaos of plugs.

Embodiment

In order to further description feature of the present utility model and advantage, now provide embodiment of the present utility model by reference to the accompanying drawings:

As shown in Figure 1, be made up of cover (1), pin (2), deck (3), base (4), screw (5).Pin (2) is inserted into pin slot (4-2) place, each for power line stock is cut bag wall by the edge of a knife (2-1) on pin (2), snaps onto connecting groove (2-2) place; Power line is through deck (3) towards outside plug, and when drawing outward, the pressure arm A (3-1) on deck (3) and pressure arm B (3-2) tightens up forward, stings tight power line, makes it not get loose; With screw (5) by cover (1) and base (4) locking, namely complete whole installation procedure.The dimensional directions of the presser feet (1-1) on cover (1) designs same pin (2) and coincide, when closing tight, presser feet (1-1) exposed portion snaps onto connecting groove (2-2) place of pin (2), and power line can not be loosened.Pin (2) is designed with positioning boss (2-3), makes it snap onto in base (4), can not loosen easily.
