Abstract
The invention relates to a plug inside frame. The plug inside frame comprises an inside frame shell and metal pins, wherein the inside frame shell is provided with sockets, the back surface of each socket is provided with a protruded piece, each protruded piece is rotationally connected to one socket, and the inner wall of each protruded piece is provided with two limiting protrusions; each limiting protrusion is in an inverted isosceles trapezoid shape, the thickness of the upper end of each limiting protrusion is 1.1mm, and the thickness of the lower end of each limiting protrusion is 0.7mm; each metal pin is provided with two positioning holes, and the shapes of the positioning holes are matched with those of the limiting protrusions. The heights of the metal pins are limited by stirring the protruded pieces to enable the limiting protrusions to be matched with the positioning holes, and the heights of terminal pins can be limited better.
Description
Technical field
The present invention relates to plug together electric power connection line together, belong to the electric power connection line field that electric equipment is used.
Background technology
Plug construction is to connect power supply and electrical equipment, and guarantee electrical equipment can be safely, a vitals of stable use.In existing attaching plug, inner bracket of power plug is for the fixed power source contact chip, and the structure of existing plug inside is too simple, the pin height of plug has standard code, but the pin height of most plug manufacturers is undertaken spacing by injection mold at present, but can cause spacing inoperatively due to reasons such as injection pressures in injection moulding process, easily cause the plug base pin height different in size.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of plug internal frame for above drawback, height that can better spacing terminal pins.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of plug internal frame, comprise internal frame housing and metal pin, described internal frame housing is provided with jack, wherein, the described jack back side is provided with lug, described lug is rotatable to be connected on jack, described lug inwall is provided with two restriction protrusion, described restriction protrusion is inverted isosceles trapezoid, its upper end thickness is 1.1mm, lower end thickness is 0.7mm, described metal pin is provided with two location holes, the shape of described location hole matches with the shape of described restriction protrusion, by stirring lug, make restriction protrusion and location hole agree with mutually to reach the purpose that limits the pin height.
Above-mentioned a kind of plug internal frame, wherein, the distance between described two restriction protrusion is 1.8mm.
Beneficial effect of the present invention is: the present invention is simple in structure, can be good at limiting the pin height, rotatable lug is set and has solved the problem that metal pin is difficult to insert jack, simple to operate, simultaneously can make pin and jack fit tightly, improve crystallized ability, having guaranteed in injection moulding process not can be because pressure etc. is former thereby cause pin length variation to occur, reduce defect rate, saved cost.
The accompanying drawing explanation
Fig. 1 is assembling plan view of the present invention
Fig. 2 is the vertical view that the present invention connects the internal frame housing
The end view figure that Fig. 3 is lug A-A of the present invention
The structure chart that Fig. 4 is metal pin of the present invention
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of plug internal frame, comprise internal frame housing 1 and metal pin 2, described internal frame housing 1 is provided with three jacks 3, wherein, described jack 3 back sides are provided with lug 4, described lug 4 is rotatable to be connected on jack 3 outer walls, described lug 4 inwalls are provided with two restriction protrusion 5, distance L between restriction protrusion 5 is 1.8mm, described restriction protrusion 5 is inverted isosceles trapezoid, its upper end thickness d 1 is 1.1mm, lower end thickness d 2 is 0.7mm, described metal pin 2 is provided with two location holes 6, the shape of described location hole 6 matches with the shape of described restriction protrusion 5, by stirring lug 4, make restriction protrusion 5 and location hole 6 agree with mutually to reach the purpose that limits pin 2 height.
The present invention is simple in structure, can be good at limiting the pin height, rotatable lug is set and has solved the problem that metal pin is difficult to insert jack, simple to operate, simultaneously can make pin and jack fit tightly, improve crystallized ability, having guaranteed in injection moulding process not can be because pressure etc. is former thereby cause pin length variation to occur, reduce defect rate, saved cost.
Here description of the invention and application is illustrative, not want by scope of the present invention restriction in the above-described embodiments, so the present invention do not limit by the present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in protection range of the present invention.
