Abstract
The invention relates to a welded nut improved structure, comprising a nut body and an extension part coaxially installed, wherein the extension part is fixedly connected with one end of the nut body, and the caliber of the extension part is smaller than the nut body; and the other end of the nut body is provided with blind holes with thread structures along an axial direction. The welded nut improved structure is characterized in that the end face of one end and/or the other end of the nut body are provided with a plurality of solder guiding grooves; and the solder guiding grooves point to the center of the end face from the peripheral part of the end planes. The welded nut has the advantages of simple structure, low manufacture cost, capability of firmly welding with assemblies such as PCB (Printed Circuit Board) boards, and the like, and capability of enduring larger tensile and torque action, and can be widely applied in the technical field of electronics and mechanical machining.
Description
Technical field
The present invention relates to a kind of nut, relate in particular to a kind of welded nut improved structure.
Background technique
Welded nut (NUT) is a kind of element of commonly using in the modern industry, and it can be applicable to such as on the electronic equipment assemblies such as pcb board.The structure of welded nut commonly used is generally as shown in Figure 1; The welded nut body 1 ' and the column extension part 2 ' that is fixedly installed on welded nut body one end that comprise a column; The other end setting of welded nut body has the blind hole 3 ' of worm structure, and the two ends end face 11 ', 12 ' of said welded nut body is smooth structure.In the practical application; In the time of on this welded nut being welded to pcb board 6 assemblies such as grade; Scolder 7 ' only can be deposited in welded nut body both ends of the surface 11 ', 12 ' with the peripheral portion of the face of weld of fitting with it; Cause welded nut when receiving tension and/or twisting force, very easily come off from assemblies such as pcb boards.
Summary of the invention
The objective of the invention is to propose a kind of structure improved welded nut that has, it can firmly weld with assemblies such as pcb boards, thereby overcomes deficiency of the prior art.
For realizing the foregoing invention purpose, the present invention has adopted following technological scheme:
A kind of welded nut improved structure; The nut body and the extension part that comprise coaxial setting, said extension part is fixedly connected with nut body one end, and the extension part bore is less than nut body; The other end of said nut body is provided with the blind hole with worm structure vertically; It is characterized in that on an end end face of said nut body and/or the other end end face complex trace scolder guiding gutter is set, said scolder guiding gutter is pointed to the central part of said end face by the peripheral portion of said end face.
Particularly, the groove width of said scolder guiding gutter is narrowed down to central part by the peripheral portion of said end face gradually.
Said scolder guiding gutter is the curvilinerar figure groove structure.
The complex trace strip groove is set on the outer wall of said nut body vertically.
At least one annular groove is set on the said extension part.
One annular groove is set on the said extension part, makes extension part be the inverted T shape structure.
Through studying for a long period of time and putting into practice; The special proposition of this case inventor technological scheme of the present invention; Be employed in complex trace is pointed to the end face central part by the end face peripheral portion scolder guiding gutter is set on welded nut one end face and/or the other end; Make scolder can in welding process, get between welded nut end face and the corresponding with it face of weld, thereby strengthened the weld strength of assemblies such as welded nut and PCB greatly, can tolerate bigger pulling force and torsion.
Preferably, said scolder guiding gutter adopt groove width by the peripheral portion of said end face to the structure that central part narrows down gradually, be beneficial to scolder and get into the scolder guiding gutter.
Preferred, said scolder guiding gutter adopts the curvilinerar figure groove structure, can make the scolder guiding gutter have bigger area, is beneficial to more scolders and gets between welded nut end faces and the corresponding with it face of weld.
Outside it, this case inventor also is employed in the mode that the complex trace strip groove is set on the outer wall of welded nut body vertically, when making the welded nut body among being assembled to electrical assembly, is difficult for rotating, and can tolerate bigger twisting force.
The mode of further optimizing is that at least one annular groove, particularly an annular groove are set on said extension part; Make extension part be the inverted T shape structure; Scolder can get in the annular groove in welding process, forms buckle structure with extension part, makes welded nut can tolerate stronger tension.
The scolder guiding gutter that is provided with on the welded nut end face among the present invention can adopt common process such as punching press to process, and the circular groove structure of said extension part can adopt common process such as casting or turning to process, and therefore is easy to processing, and is with low cost.
Compared with prior art; Beneficial effect of the present invention is: this welded nut is simple in structure, and is cheap for manufacturing cost, can firmly weld with assemblies such as pcb boards; And can tolerate bigger pulling force and twisting force, can be widely used in electronics, Machining Technology field.

Embodiment
Shown in Fig. 2～5; The welded nut of present embodiment comprise coaxial setting nut body 1 and with extension part 2; Said extension part is fixedly connected with nut body one end, and the extension part bore is less than nut body, and the other end of said nut body is provided with the blind hole 3 with worm structure vertically.On the one end end face 12 of said nut body the scolder guiding gutter 5 that complex trace has the curvilinerar figure groove structure is set; Said scolder guiding gutter points to the central part of said end face by the peripheral portion of said end face, and the groove width of scolder guiding gutter is narrowed down to central part by the peripheral portion of said end face gradually.Simultaneously, complex trace strip groove 4 is set on the outer wall of said nut body vertically, and an annular groove 21 is set on the said extension part, make extension part 2 be the inverted T shape structure.
Further, also the scolder guiding gutter can be set on the other end 11 of said nut body, its structure can be similar to welding guiding gutter structure shown in Figure 3.
Certainly, also some annular grooves of space set on the said extension part, its effect is similar to one above-mentioned annular groove.
The welded nut of present embodiment in winding to 6 last times of pcb board; Scolder 7 can get between the corresponding with it face of weld of welded nut one end face 12 and other end 11 and difference through the scolder guiding gutter, and the annular groove Nei Zekeyin of extension part fills scolder and form buckle structure with pcb board.Simultaneously, the strip groove that is provided with on the nut body outer wall also can make nut body and pcb board be difficult for relatively rotating.
Mat foregoing description Ying Kezhi, the present embodiment welded nut is simple in structure, and is cheap for manufacturing cost, can firmly weld with assemblies such as pcb boards, and can tolerate bigger pulling force and twisting force.
The foregoing description is merely explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
