Therefore, be necessary to design a kind of novel fixed structure and use the electric connector of this fixed structure, to overcome above-mentioned defective.
[summary of the invention]
The electric connector that the purpose of this utility model is to provide a kind of fixed structure and uses this fixed structure, it can simplify welding procedure, and the fixedly strength that is obtained also can satisfy instructions for use.
In order to reach above-mentioned creation purpose, the utility model fixed structure, it can cooperate with the welding hole on the circuit board so that insulator is fixed on the circuit board, the corresponding welding hole of this insulator is provided with fixed body, contiguous this fixed body is provided with scolder, can enter welding hole after this scolder heat fused fixed body is fixed in the welding hole.
The utility model electric connector, it can be fixed on the circuit board that is provided with welding hole, and this electric connector comprises insulator, and the corresponding welding hole of this insulator is provided with fixed body, contiguous this fixed body is provided with scolder, can enter welding hole after this scolder heat fused fixed body is fixed in the welding hole.
Compared with prior art, the utility model fixed structure and use the electric connector of this fixed structure can simplify welding procedure, and can obtain to satisfy the fixedly strength of instructions for use.

[embodiment]
Below in conjunction with the drawings and specific embodiments to the utility model fixed structure and use the electric connector of this fixed structure to be described further.
As Fig. 4, shown in Figure 5, the utility model electric connector 10 includes insulator 11 and plurality of conductive terminals (not drawing among the figure), and it can be installed on the circuit board 20 and electrically conduct to reach with circuit board 20.This circuit board 20 is provided with some welding holes 21 (welding hole is to be formed by the metal material that can weld by mode settings such as plating) around hole, this insulator 11 is provided with fixed structure, this fixed structure comprises the tin sheet 14 that is positioned at the corresponding welding hole 21 in insulator 11 bottoms and is provided with the integrally formed plastic column 13 of insulator 11 and contiguous this plastic column 13, when heating, can enter welding hole 21 after these tin sheet 14 melted by heat fills the gap between plastic column 13 and the welding hole 21, fix plastic column 13, thereby the insulator 11 of electric connector 10 is securely fixed on the circuit board 20.
Fixed structure also can comprise the metallic object that is fixed on the insulator, and it is fixing with metallic object and welding hole welding to enter welding hole after the scolder melted by heat, thereby the insulator of electric connector is securely fixed on the circuit board.This metallic object 30 can comprise larger-size head 31, inserts from top to bottom (as shown in Figure 6) in the insulator 11, also can comprise posting the sheet head 32 (as Fig. 7, shown in Figure 8) that is fixed on insulator 11 bottoms.The stiff end of this metallic object is not limited to column, also can be other shapes such as sheet.
Fig. 9, Figure 10 shows that the utility model fixed structure and use the 4th embodiment of the electric connector of this fixed structure.Compare with above-mentioned first embodiment, the present embodiment difference is that this fixed structure is to replace the tin sheet with the tin ball, be that insulator 11 is being concaved with accepting groove 15 with the circuit board facing surfaces, tin ball 40 is arranged in accepting groove 15, like this, during heating, also can enter welding hole 21 after tin ball 40 melted by heat filling of the gap between plastic column 13 and the welding hole 21 is fixed plastic column 13.
Equally, fixed body also can be the metallic object that is fixed on the insulator, this metallic object can comprise larger-size head 31, insert from top to bottom (as Figure 11) in the insulator 11, if and head is a sheet, this sheet head 50 need have through hole 51, makes can pass through hole 51 after the tin ball fusing and flow in the welding holes (as Figure 12, Figure 13, Figure 14).
With respect to the harpoon fixed structure, the utility model does not need the bigger power that is pressed into, and is therefore easy to operate, can not limit the SMT processing procedure; With respect to DIP welding fixed form, the utility model need not be crossed the tin stove, so can simplify welding procedure; With respect to conventional metals pin welding fixed form, fixedly strength of the present utility model is much bigger, can reach instructions for use.
