Abstract

The utility model provides a novel structure of a terminal. The terminal is provided with a base pin part and a wire clamping part. The utility model is characterized in that the position on the base pin part close to an open end is provided with a circular hole; the base pin part is provided with the end part of the circular hole; the thickness and the width of the utility model are both smaller than the thickness and the width of the main body of the base pin; the surrounding surface of the end part and the wall surface of the circular hole are bespread with insulating material, forming a fixed insulating layer; an isolated end is formed on the open end part of the base pin part by the insulating layer. The utility model has the advantages that plugs can be plugged stably; electric current can be stably conducted; electric appliances can be protected; short circuit spark can avoided; electric shock caused by the contact to the exposed base pin part can be avoided.

Description

The terminal new construction

The utility model relates to a kind of end piece that two or more terminals are arranged.

The terminal structure of traditional plug is a terminal strip of making continuous shape with the metallic conduction material, and the shape of each terminal 10 all comprises the clamp portion 12 of a tabular pin portion 11 and a semiarc shape on the terminal strip.Via pin portion 11 reverse, continuously portion's severing is independent terminals 10, clamp portion 12 cramping power supply bare wires, and terminal position is irritated the molded processing procedure such as the outer seat of plug of doing and is finished a plug.And this plug is to insert conducting electric current in the socket with pin portion 11.Correct and safe plug using priciple should be that the whole pin of plug portion 11 is all inserted in the socket, and the degree of depth in the plug insertion socket is enough, just can reach stable purpose of planting.But many users have but neglected above-mentioned using priciple easily when the plant plug, only the part of pin portion 11 are inserted in the socket, think as long as the conducting electric current does not notice but whether plug is planted reliable.Though do not insert the purpose that steady plug still can reach conduction sometimes, but plug stationarity deficiency, cause the guide card loose contact in pin portion 11 and the socket, when electric current occurring easily and during conducting and the problem of interrupting, not only therefore electric equipment damages easily, and the easier Da Hua that produces because of loose contact increases its danger.And the unsettled plug of planting, its pin portion 11 exposes outside socket near the end of the outer seat of plug, and child points and touches or put into conductive body easily so that danger such as electric shock or short circuit take place.

The purpose of this utility model is that a kind of improved terminal new construction will be provided, and it can guarantee that plug plants stablely, can avoid the electric current instability, easily have its problem such as fragile of short circuit Danger Electric shock risk, electrical appliance to produce.

Utility model is achieved in that this pin portion has the end of circular hole, if its thickness and width are all less than the thickness and the width of this pin portion body, insulating material is coated on the side face and the circular hole wall of this end, form a fixing insulating barrier, the open end that insulating barrier constitutes pin portion is an insulating end.

The setting of its insulating end of the utility model mat, pin portion must be inserted socket fully during use, the guide card that just can make socket aperture contacts turn-on power with pin portion body, thereby guarantee that plug can firmly be plugged in the socket, but electric current stable supplying electrical equipment, the useful life of assurance electrical equipment, the danger that also can avoid conducting at intermittence repeatedly and produce spark, simultaneously, because pin portion inserts socket fully, can not produce the Danger Electric shock risk that finger touches pin portion again.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the axonometric drawing of traditional continous way terminal strip.

Fig. 2 is the utility model terminal new construction continous way terminal strip axonometric drawing.

Fig. 3 is the terminal coated insulation axon mapping of the utility model terminal strip.

Fig. 4 is an A-A cutaway view among Fig. 3.

Fig. 5 is a B-B cutaway view among Fig. 3.

Fig. 6 is that the utility model terminal is made the plug construction axonometric drawing.

With reference to Fig. 2, the terminal new construction, it is the terminal strip of making continuous shape with the metallic conduction material, each terminal 20 all comprises the clamp portion 22 of a tabular pin portion 21 and a semiarc shape on terminal strip, pin portion 21 nearly open ends are provided with a circular hole 211, one of circular hole 211 functions are when carrying out clamp in the clamp portion 22 of terminal, can make terminal position carry out above-mentioned processing procedure with the circular hole 211 of the slotting two-terminal 20 of a setting element string.

With reference to Fig. 3,4,5, the end of these pin portion 21 tool circular holes 211, if its thickness and width are all less than the thickness and the width of these pin portion 21 bodies, and carry out insulating material in this end and irritate mould, make insulating material be coated on side face and this circular hole 211 walls of this end, mat is fed into the insulating material of these circular hole 211 walls, insulating barrier 23 is fixed is coated on the open end of pin portion 21, and making open end is an insulating end.

With reference to Fig. 6, the terminal 20 that the utlity model has insulating end is located with an interior die holder 40, outer seat 31 fillings of carrying out plug 30 again are molded as complete plug 30, in use, the pin portion 21 that must will expose plug 30 outer seats 31 inserts in the socket (figure does not show) fully, make in the socket aperture guide card be able to contact with pin portion 21 bodies, power supply just is able to conducting.In other words, if the user fully inserts the pin portion 21 of plug 30 in the socket apertures because of carelessness, then plug 30 promptly contacts with guide card in the socket aperture with the insulating end that is covered with insulating barrier 23, and power supply then can't conducting.Such result can inform the firmly plant of its plug 30 of user significantly, and supervises the user plug 30 to be goed deep in socket again, enters socket fully until pin portion 21 and firmly plants; So, these pin portion 21 bodies can contact with the guide card in the socket aperture; So far, except the major function of finishing power turn-on, it is planted fully can increase the stability of plug, pin portion 21 contacts with the guide card of socket sustainedly and stably, electrical appliance is supplied with on electric current all-the-time stable ground, in the useful life that also can guarantee electrical appliance, avoids electrical appliance to damage; Also can avoid plug, socket because of repeatedly intermittently conducting produce the hazards of spark.And the user because pin portion 21 imbeds in the socket fully, so finger can only be held and touch on the outer seat 31 of plug 30, does not have the danger of error shock when pulling out plug.

Claims
