Description
Technical Field
The invention relates to a connector, in particular to a contact type electric connector.
Background
The connector is used as an important component of modern signal transmission, the performance requirements of the connector on respective applicable occasions are increasingly improved, and the pin and jack type connector with the traditional structure is limited by a pin hole plugging mode, the axial length of the connector, the size precision of a pin hole joint surface and the like, so that the use performance of the connector is directly influenced, and the applicability of the occasions is limited.
Disclosure of Invention
The invention provides a contact type electric connector which is simple in structure, can meet the requirements of small-size axial insertion and large insertion joint surface and is beneficial to improving transmission performance.
The technical scheme adopted by the invention is as follows: a contact type electric connector comprises a socket and a plug, and is characterized in that: the socket comprises a socket shell and is characterized in that more than one jack piece with outward openings and a spherical concave structure is arranged on the inserting end face of the socket shell, a plurality of pin pieces corresponding to the jack pieces are connected on a pin insulator in the socket shell of the plug in a penetrating manner, the head of each pin piece extending out of the pin insulator is of a ball head structure corresponding to the spherical concave structure of the jack piece, each pin piece comprises a spring needle and a pin seat, the spring needle and the pin seat are connected in a penetrating cavity in the middle of the pin insulator in an inserting manner, a pressure spring is sleeved outside the penetrating cavity, and the pressure spring is abutted between the spring needle and the rear part of the penetrating cavity.
Furthermore, the tail part of the spring needle is sleeved on the needle inserting seat in a matching manner.
Furthermore, a sheath is arranged outside the spring needle and the needle base in the penetrating cavity in the middle of the needle inserting insulator, and a pressure spring is sleeved outside the sheath.
Furthermore, the needle inserting piece is of a hair button structure.
The invention improves the traditional inserting structure of the contact pin and the jack with longer axial length into the inserting combination of the ball head and the spherical concave structure with shorter and larger contact surface and more stable, is beneficial to simplifying the axial length of the connector, meets the requirements of small-size axial inserting and large inserting combination surface, and can further improve the transmission performance.
