Description

Bayonet connector

Technical field

The utility model refers to a kind of upper surface that can be arranged at a female circuit board especially relevant for a kind of bayonet connector, and the bayonet connector that supplies a sub-circuit board to plant.

Background technology

The applicant proposes " bayonet connector " relevant with this case (application case number be No. 92216704) Taiwan utility application on September 17th, 2003, this bayonet connector is arranged at the upper surface of a female circuit board, and for sub-circuit board plant, to realize electrically connecting this mother's circuit board and sub-circuit board, this bayonet connector comprises: insulating body, it has a main part, these main part two ends are extended with elasticity button gripping arm respectively, the relative inner of this elasticity button gripping arm is provided with projection, and this projection bottom surface is in order to prop up the top surface edge of a sub-circuit board; Several terminals, it is arranged at this main part; And grounding assembly, it is positioned on this elasticity button gripping arm, this grounding assembly has a side shell fragment, bending is extended with a grounding parts on this side shell fragment, this grounding parts bending is to the upper surface of this sub-circuit board and contact shoe circuit board, and the projection of insulating body is between this grounding parts bending place and sub-circuit board.Above-mentioned bayonet connector, the grounding parts that can make the upper surface of its grounding assembly contact shoe circuit board can wrongful not the pulling of factor circuit board and the generation of the situation that causes rupturing.

When desire is taken out sub-circuit board, need outwards to pull open earlier elasticity button gripping arm, make the breach of the binding block disengaging sub-circuit board side on the elasticity button gripping arm, but and elasticity button gripping arm when outwards pulling contact be close to the side shell fragment of the grounding assembly in its outside, outwards move in order to the interlock grounding parts, make grounding parts break away from the upper surface of sub-circuit board, so just can successfully take out sub-circuit board.

Yet, because the side shell fragment of grounding assembly is to have the elasticity and the long arm of force, therefore the side shell fragment of outwards pulling this grounding assembly of contact when this elasticity button gripping arm is outside when mobile, the side shell fragment can produce bending, and make this side shell fragment have only free end to produce bigger displacement, and that the fulcrum place that joins with grounding parts on the side shell fragment produces displacement is less, so elasticity button gripping arm need outwards pull bigger amplitude, can guarantee that just grounding parts breaks away from the upper surface of sub-circuit board.

Summary of the invention
