Abstract
The present invention relates to a kind of plug internal frame, including 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 rotatably attached 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 hole, two location, the matching form of the shape in hole, described location and described restriction protrusion closes, restriction protrusion is made to agree with, with hole, location, the purpose reaching to limit pin height mutually by stirring lug, can the height of more preferable spacing terminal pins.
Description
Technical field
The present invention relates to plug together electric power connection line together, belong to the electricity of electric equipment
Connecting line field, source.
Background technology
Plug construction is to connect power supply and electrical equipment, and ensures that electrical equipment can safe and stable use
A vitals.In existing attaching plug, inner bracket of power plug is used for fixed power source
Contact chip, and the structure of existing plug inside is excessively simple, the pin height of plug is to have standard
Regulation, but the pin height of current most of plug manufacturer is to be entered by injection mold
Row is spacing, but spacing does not acts as owing to the reasons such as injection pressure can cause in injection moulding process
With, easily cause plug base pin height different in size.
Summary of the invention
The technical problem to be solved is in a kind of plug of above drawback offer
Frame, it is possible to the height of more preferable spacing terminal pins.
For solving above-mentioned technical problem, the technical scheme is that
A kind of plug internal frame, including internal frame housing and metal pin, described internal frame housing sets
Having jack, wherein, the described jack back side is provided with lug, and described lug is rotatably attached to
On jack, described lug inwall is provided with two restriction protrusion, and described restriction protrusion is inverted
Isosceles trapezoid, its upper end thickness is 1.1mm, lower end thickness is 0.7mm, and described metal is inserted
Pin is provided with hole, two location, the shape in hole, described location and the matching form of described restriction protrusion
Close, make restriction protrusion agree with mutually with hole, location to reach restriction pin height by stirring lug
Purpose.
Above-mentioned a kind of plug internal frame, wherein, the distance between said two restriction protrusion is
1.8mm。
The invention have the benefit that present configuration is simple, it is possible to well limit pin high
Degree, arrange rotatable lug solve metal pin be difficult to insert jack problem, operation letter
Single, pin can be made to fit tightly with jack simultaneously, improve crystallized ability, it is ensured that at note
Because of former tang length that thus results in such as pressure, change will not occur during moulding, reduce substandard products
Rate, has saved cost.
Accompanying drawing explanation
Fig. 1 is the assembling plan view of the present invention
Fig. 2 is the top view that the present invention connects internal frame housing
Fig. 3 is the side view figure of lug A-A of the present invention
Fig. 4 is the structure chart of metal pin of the present invention
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As it can be seen, a kind of plug internal frame, including internal frame housing 1 and metal pin 2, described
Internal frame housing 1 be provided with three jacks 3, wherein, described jack 3 back side is provided with lug
4, described lug 4 is rotatably attached on jack 3 outer wall, and described lug 4 inwall sets
Having two restriction protrusion 5, distance L between restriction protrusion 5 is 1.8mm, described restriction protrusion
5 is inverted isosceles trapezoid, and its upper end thickness d 1 is 1.1mm, lower end thickness d 2 is 0.7mm,
Described metal pin 2 is provided with hole 6, two location, and the shape in hole, described location 6 is with described
The matching form of restriction protrusion 5 closes, and makes restriction protrusion 5 and hole 6, location by stirring lug 4
Agree with the purpose reaching to limit pin 2 height mutually.
Present configuration is simple, it is possible to well limits pin height, arranges rotatable lug
Solve metal pin and be difficult to insert the problem of jack, simple to operate, can make simultaneously pin with
Jack fits tightly, and improves crystallized ability, it is ensured that will not be because of pressure etc. in injection moulding process
There is change in the former tang length that thus results in, reduces defect rate, has saved cost.
Here description of the invention and application is illustrative, is not wishing to limit the scope of the present invention
In the above-described embodiments, therefore the present invention is not limited system by the present embodiment, and any employing equivalence is replaced
The technical scheme exchanged for is all in scope.
