Description

The bayonet connector combination

Technical field

The utility model relates to a kind of bayonet connector combination, the fixed structure that is particularly related to a kind of electronic cards is located away from connector, with localized electron card firmly, and have the easy disassembling of electronic cards concurrently, and the bayonet connector combination that the circuit layout area of electronic cards is increased.

Background technology

Connector and electronic cards that the various modularization of installing electronic product matches, for guaranteeing electrically conducting each other, connector and electronic cards must keep the steadiness that is connected, the transmission signal normally to avoid vibrations to get loose.

Existing bayonet connector combination sees also Fig. 1, and it comprises circuit board 2a, connector 1a and electronic cards (figure does not show).This connector 1a is located on this circuit board 2a, and connector 1a comprises an insulating body 10a, plurality of terminals 11a and two metal guard bar 12a.This insulating body 10a has a base portion 13a, this base portion 13a two ends extend bogie side frame 14a respectively, the relative inner of this two bogie side frame 14a is provided with slot 15a, these terminals 11a one end is located at this base portion 13a, the other end is electrically connected on the circuit board 2a, and this two metal guard bar 12a is located at the relative outside of two bogie side frame 14a respectively, and metal guard bar 12a has holding parts 16a and is fixed on the bogie side frame 14a, and this electronic cards is inserted among the slot 15a of two bogie side frame 14a, and electrically connects with these terminals 11a.

Above-mentioned existing bayonet connector combination, at first, when connector is fixedly arranged on circuit board, the connector shallow storage space that circuit board is reserved, can influence the circuit layout and the space utilization of circuit board,, the circuit design flexibility of circuit board be lowered as the extension kenel of two bogie side frames.

Secondly, when electronic cards was inserted in the slot, the distance of the restricted width of electronic cards between two bogie side frames made the design space of electronic cards can't do appropriate expansion with demand because of limitation.

Moreover two bogie side frames are plastic material, and rigidity is relatively poor, and the kenel of its extension, easily because of pull deflection, distortion or even rupture, cause bogie side frame to lose locating effect to electronic cards.
