The problem to be solved by the utility model is to provide the plug capable of avoiding wire disconnection, which has the advantages of simple process, low cost, high production efficiency, stable quality, safety and reliability. The technical scheme solving the problem includes that the plug is provided with a plug pin which is arranged on an internal bladder through a clamping slot, one end of the plug pin is electrically connected with a wire, and PVC layers are coated at the joints of the outer part of the internal bladder, the internal bladder and the wire. The plug is characterized in that the plug pin is connected with the internal bladder through a shift-prevention clamping structure. The plug provided by the utility model is mainly applied to various electric appliances.
Description
Technical field
The utility model relates to a kind of appliance plug, and especially a kind of non-rewirable plug is mainly used in the various electrical equipment.
Background technology
Progress along with society, the raising of people's living standard, more and more be unable to do without various electrical equipment in the daily life, plug is as an indispensable part often plug in use of electrical equipment, thereby the quality of plug quality also becomes the standard that people select electrical equipment for use.Conventional GB non-rewirable plug is the quadric injection mould moulding, as shown in Figure 1, at first with inner bag, latch and electric wire injection mo(u)lding together, finishes the location of latch in inner bag; And then it is plastic to carry out PVC outside, as shown in Figure 2, complex process, waste material, the cost height, production efficiency is low, there is potential safety hazard in the quality instability, used of a specified duration after, latch occurs loosening easily, influences the normal use of plug.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of technology simple, cost is low, the non-rewirable plug that production efficiency height and steady quality are safe and reliable.
The technical solution adopted in the utility model is: non-rewirable plug, have by draw-in groove and be installed in latch on the inner bag, latch one end is electrically connected with electric wire, outer and the inner bag of inner bag is surrounded by the PVC layer with the electric wire junction, it is characterized in that: between described latch and the inner bag by preventing that the play interface arrangment is connected.
Described interface arrangment comprises the last play locking boss that is arranged on the inner bag draw-in groove one side inwall, offer down play locking groove on another sidewall on the other side, the following play locking boss that punching press forms on the latch embeds in the following play locking groove, last play locking boss embeds in the last play locking groove that punching press forms on the latch, and the vertical range between last play locking boss and two locking faces of following play locking groove equates with vertical range between following play locking boss and two locking faces of last play locking groove.
Above-mentioned four locking faces are all vertical with the latch length direction, and latch can run-off the straight during with the assurance assembling.
The beneficial effects of the utility model are: realize the location of latch in inner bag by the last play locking boss that cooperatively interacts, last play locking groove and following play locking boss, following play locking groove between latch and the inner bag in the utility model, guaranteed the firmness that is connected between latch and the inner bag, the outside uses PVC plastic again, not only moulding process is simple, saved material, reduce cost, improved production efficiency and quality stability, easy to use safe and reliable.

Embodiment
Extremely shown in Figure 8 as Fig. 3, present embodiment has by draw-in groove and is installed in latch 1 on the inner bag 2, latch 1 one ends are electrically connected with electric wire 3, the other end extends inner bag 2 outsides, outer and the inner bag 2 of inner bag 2 is surrounded by PVC layer 4 with electric wire 3 junctions, between described latch 1 and the inner bag 2 by preventing that the play interface arrangment is connected.
Described interface arrangment comprises the last play locking boss 5 that is arranged on the inner bag 2 draw-in grooves one side inwall, offer down play locking groove 6 on another sidewall on the other side, on latch 1, carry out punching press, wherein three limits are washed open, form down play locking boss 7 along another limit to a side bending certain angle then, then form play locking groove 8 in an other side accordingly, and the vertical range between last play locking boss 5 and 6 two locking faces of following play locking groove equates with vertical range between following play locking boss 7 and 8 two locking faces of last play locking groove, after guaranteeing that latch 1 snaps in draw-in groove on the inner bag 2, play up and down can not take place.Simultaneously, above-mentioned four locking faces are all vertical with latch 1 length direction, and latch 1 can run-off the straight during with the assurance assembling.
The erection sequence of this plug: at first latch 1 and electric wire 3 are riveted, then latch 1 is inserted in the inner bag 2 corresponding draw-in grooves, draw-in groove is established chamfering near medial extremity, with convenient latch 1 is inserted in the draw-in groove, promptly make the following play locking boss 7 on the latch 1 embed in the following play locking groove 6, in the last play locking groove 8 that last play locking boss 5 embeds on the latch 1, the locking face of play locking boss 5 and last play locking groove 8 fits on this moment, at present the locking face of play locking groove 6 and following play locking boss 7 fits together, uses PVC layer 4 plastic at last again.
