Description
Technical field
The utility model relates to a kind of connector technique field, and more particularly, it relates to a kind of modified node method of circuit board connector.
Background technology
Connector is the requisite components and parts of electronic technology field, particularly use connector on circuit boards, especially require that it has very high switching performance, as shown in Figure 4, existing splicing type connector comprises an insulator 3, conducting terminal (contact pin 2) and a shielding casing 1, conducting terminal 2 fills through insulator 3 and is fixed on insulating body 3, shielding casing 1 be placed in insulator 3 outer and fixing on circuit boards, conducting terminal one end 4 is inserted in the welding hole of circuit board, the conducting terminal other end 7 is for other source devices of grafting, the connector of this splicing type is also contact pin connector, the contact pin of this connector in use, owing to being often subject to the pulling force that grafting produces, the contact pin be fixed on insulating body easily loosens or comes off, produce loose contact or useful life short.Therefore, the structure of the contact pin improving this connector is needed and coordinated insulation body is fixed in housing.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the modified node method providing a kind of circuit board connector, improves contact pin fixed performance in the connectors, improves the useful life of connector.
For achieving the above object, the utility model provides following technical scheme: a kind of modified node method of circuit board connector, comprise housing, insulator and contact pin, it is characterized in that: contact pin is fixed in housing by described insulator, described contact pin comprises weld part, the first lug boss, the second lug boss and Plug Division from top to bottom successively, the radial width of described first lug boss is greater than the radial width of the second lug boss, described first lug boss is pressed on insulator relative to the end face laminating of insulator, and described second lug boss is through insulator.By adopting technique scheme, when connector is connected with circuit board, weld part welding on circuit boards, when Plug Division is subject to the pulling force of grafting generation, first lug boss insulated body blocks and cannot move down, and insulator is by support first lug boss thus support whole contact pin, and contact pin can not be loosened or come off, substantially increase the fixed performance of contact pin, thus improve the useful life of connector.
The utility model is set to further: weld part, the first lug boss, the second lug boss and Plug Division are one-body molded.
By adopting technique scheme, weld part, the first lug boss, the second lug boss and Plug Division are one-body molded, improve intensity and the switching performance of contact pin.
The utility model is set to further: the end face that the first lug boss deviates from insulator is provided with and adds high level, and add between high level and weld part and form groove, the junction of described second lug boss and Plug Division is provided with chamfering.
By adopting technique scheme, when weld part welds on circuit boards, welding fluid can flow in groove by welding hole, strengthens weld strength; Chamfering can strengthen the bonding strength of the second lug boss and Plug Division.
The utility model is set to further: the end of weld part and Plug Division is provided with circular arc chamfering.
By adopting technique scheme, contact pin more easily connects other terminals when connecting, and makes to be not easy to insert partially in connection, and meanwhile, contact pin is also not easy scratch circuit board.
