FLACHSTECKBUCHSE

The invention relates to a flat blade jack ( 1 ) with a socket shaft to accommodate, in an electrically contacting manner, a flat connector. The socket shaft comprises at least one comb-like multitude of essentially parallel contact bridges ( 3 ) that extend in the direction of plugging, which comb-like multitude is arranged on at least one broad side of the socket shaft. In this arrangement the contact bridges ( 3 ) are curved towards the middle of the socket shaft. According to the invention the flat blade jack ( 1 ) is characterised in that the section of the contact bridges ( 3 ), which section is curved towards the middle of the shaft, in the region of the contact zone with the flat connector comprises more than one vertex ( 6, 7 ). Thanks to the flat blade jack according to the invention it becomes possible to particularly reliably design electrical plug-type connections, for example with contact blades of flat connectors or of fuses or relays. Apart from providing considerable improvements relating to current-carrying capacity, reliability and evenness of the force gradient during plug-in, the invention at the same time provides economic advantages due to the ability to efficiently produce flat blade jacks.
