Description

Electric connector

The utility model is a kind of electric connector, refer in particular to a kind of have can adjust configuration is retained on the holding unit of circuit board different fixing position for its pinboard electric connector.

General electronic component is when being soldered to circuit board; for this electronic component before and after making welding can remain on the former allocation; in order to welding precisely and welding effect good; usually can on these electronic components, holding unit be set; electronic component can be fixed on the circuit board on the one hand and carry out in order to welding processing; also can adopt metal material to make these holding units and it is welded on the circuit board on the other hand, so that different grounding paths to be provided.The electric connector relevant with the utility model, its set holding unit are a kind of electric connector that makes and can be retained on the circuit board face so that the device of electric connector and circuit board welding.The holding unit of existing electric connector according to the difference of its fixing position and fixing function, and has different configuration designs, as No. the 79203382nd, 80213095,78204719, TaiWan, China patent etc.But these existing electric connector holding units and the affixed position of circuit board are fixedly installed on electric connector usually and are abutted against root edge position in circuit board, and it is provided with form and is all single and no change.Like this, error is arranged slightly in case meet the corresponding hole location of circuit board, or engages with circuit board because of design needs to change, the position of fixing, the fixing holding unit of these configurations can't utilize again and must remake, and cause great cost to waste.Especially as the electronic installation of notebook computer and so on, under the requirement of different user demands, gradually towards compact designer trends, therefore, how to dwindle the whole height and the usable floor area of the electronic component of circuit board and joint thereof, will become designer's important topic.And the situation that previous designs changes will directly impact the design of associated electronic components such as electric connector.Thereby electric connector and member thereof such as holding unit person be if possess versatility is not arranged, and will become great cost burden and make manufacturer lose competitiveness.

Main purpose of the present utility model, be to provide a kind of have can make the electric connector of multi-angle bending with the holding unit that changes the fixing position at any time, it can make electric connector be retained on any position on the circuit board and increase its versatility, and the holding unit of this electric connector can be according to actual its configuration of fixing position change, its range of application is increased, need not make other holding unit separately for the fixing position change, effectively to reduce cost.

The utility model electric connector comprises terminal base, terminal, combination member and holding unit, it is characterized in that: holding unit is through being stamped to form continuously by a plate spare, it includes continuous bending and therebetween forms fluted clamp, top board and back plate, and the mid portion at clamp offers the bayonet socket that is arch door shape, to bridge and to organize solid on combination member, and forming an arm plate towards turning up away from the groove direction in back plate root edge, vertically bend down this arm plate appropriate position pinboard.All can depend on concrete needs between between this back plate and the top board or back plate and the arm plate and bending goes out special angle, the angle demand when being inserted in diverse location to adapt to pinboard, and make the electric connector can be all applicable on the winding position of any circuit board.

Compare prior art, because adopting, the utility model can adjust configuration is retained on circuit board different fixing position for its pinboard holding unit, can be according to actual its configuration of fixing position change to change the fixing position at any time, electric connector is had to be retained on any position on the circuit board thereby to have versatility widely, and need not make other holding unit separately for the fixing position change.

The utility model is described in further detail below in conjunction with drawings and Examples:
