Abstract
The utility model provides a kind of three to insert formula plug internal frame, and comprise stake body and pin terminals, pin terminals comprises wire connecting portion and pin part, and wire connecting portion and pin part are formed by flat material integrated punching; Wire connecting portion is hollow cylinder; Pin part comprises the plug-in mounting section be inserted in stake body, and the surface of plug-in mounting section is formed with outwardly dentation line; Described plug-in mounting section and pin installing hole interference fit, make pin terminals firmly be installed in stake body.The utility model have technique simple and easy, without the need to injection moulding production, production cost is low, product stability is good advantage.
Description
Technical field
The utility model relates to electrical accessorie field, is specially a kind of three and inserts formula plug internal frame.
Background technology
In prior art, attaching plug includes pin terminals and stake body, by injecting or being fixed between pin terminals and stake body.As the Chinese patent that publication number is CN 202259822, disclose a kind of integrated three-pin plug, the structure of its pin terminals as depicted in figs. 1 and 2, comprises wire connecting portion 1' and pin part 2'; Wire connecting portion is column, and the top of column is provided with the chamfering to column center position, is provided with wiring groove in column; Pin part is flat-shaped, and pin part is provided with location hole 21'.Pin terminals is generally stamped to form by columned raw material, and wire connecting portion is directly a raw-material part, and pin part is that cylinder strikes out flat-shaped body, then casts location hole.Cylinder material punching press pin terminals consistency is out poor.Usual three modes of production of inserting formula plug internal frame are fixed by three pin terminals relative positions, then in pin terminals, carry out injection moulding, produces and make the stake body be nested in pin terminals.But when injection moulding, do not have enforceable machinery location between pin terminals and stake body, so in the process of injection moulding extruding, the relative position between pin terminals easily changes, and causes the product produced not meet standard-required.And the technique of injection moulding also more complicated and trouble, during production in enormous quantities, cost is high.For this reason, design a kind of easily manufacture, low, the constitutionally stable plug internal frame of production cost is needed.
Summary of the invention
The plug internal frame that the purpose of this utility model is to provide that a kind of structure is simple, production cost is low, connective stability between pin terminals and stake body is good.Concrete technical scheme of the present utility model is as follows:
A kind of three insert formula plug internal frame, comprise stake body and pin terminals; Described stake body is provided with 3 pin installing holes; Described pin terminals has 3, and a pin terminals correspondence is arranged in a pin installing hole; Described pin terminals comprises wire connecting portion and pin part; Especially, described wire connecting portion and pin part are by flat material integrated punching; Described wire connecting portion is hollow cylinder; Described pin part comprises the plug-in mounting section be inserted in pin installing hole and the extension section extended outside pin installing hole; The surface of described plug-in mounting section is formed with outwardly dentation line; Described plug-in mounting section to be inserted in pin installing hole and with pin installing hole interference fit.
Preferably, described dentation line is positioned on the narrower surface of plug-in mounting section.
Preferably, the wire connecting portion of described pin terminals, the edge at its top is formed with arc angling to direction, axis.
Preferably, the pin part of described pin terminals, its end is arcwall face, facilitates pin terminals to be plugged in pin installing hole.
Preferably, the central point of 3 pin installing holes on described stake body is separately positioned on 3 angles of an equilateral triangle.
The utility model plug internal frame, pin terminals and stake body are independent separately manufactures, during installation, the plug-in mounting section of pin terminals is squeezed in pin installing hole, the diameter of plug-in mounting section is a bit larger tham the aperture of pin installing hole, plug-in mounting section and pin installing hole interference fit, make pin terminals stably be inserted in stake body; After installation, the wire connecting portion of pin terminals is placed in the top of stake body, and the extension section of pin part is placed in the below of stake body.Pin internal frame of the present utility model is without the need to carrying out Shooting Technique in assembling process, and pin terminals and stake body independently manufacture, and be applicable to batch production, the consistency of product is good.Especially pin terminals is stamped to form by flat material, traditional pin terminals is by columned material punching press, and columned material strikes out the pin part of flat, the more difficult control of size of finished product, the consistent type of product is poor, easily causes end product quality uneven.The utility model has the advantages such as technique is simple and easy, production cost is low, product stability is good, percent defective is low.

Embodiment
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing:
As Fig. 6, a kind of three insert formula plug internal frame, comprise stake body 1 and pin terminals 2.
As Fig. 3, stake body 1 is provided with 3 pin installing holes, the central point being respectively the first pin installing hole 11, second pin installing hole 12 and the 3rd pin installing hole 13, first pin installing hole 11, second pin installing hole 12 and the 3rd pin installing hole 13 forms equilateral triangle.
As Fig. 4 and Fig. 5, pin terminals 2 comprises wire connecting portion 21 and pin part 22.Wire connecting portion 21 and pin part 22 are for by flat material integrated punching.Wire connecting portion 21 is hollow cylinder, and the top of wire connecting portion 21 forms arc angling to direction, axis.Pin part 22 comprises the extension section 222 of plug-in mounting the section 221 and wire connecting portion far-end adjoined with wire connecting portion.The side of plug-in mounting section 221 is formed with outwardly dentation line 223, and dentation line 223 is positioned on the narrower surface of plug-in mounting section 221.The end of pin part 22 is arcwall face.
As Fig. 6, a pin terminals correspondence is arranged in a pin installing hole.The aperture of pin installing hole 11 and the width of extension section 222 are makeed an appointment but are less than the width of plug-in mounting section 221.Plug-in mounting section 221 is inserted in pin installing hole 11, and plug-in mounting section 221 and pin installing hole 11 interference fit, make pin terminals 2 stably be inserted in stake body 1.Wire connecting portion 21 is placed in the top of stake body 1, and extension section 222 is placed in the below of stake body 1.
