Abstract

The invention discloses an electric connector, and the electric connector comprises at least one terminal assembly, and the terminal assembly comprises an insulating block; a pair of signal terminals which are fixed on the insulating block, wherein the surface type welding parts of the pair of signal terminals are arranged along a first direction, each surface type welding part is provided with a welding surface facing a second direction, the second direction is perpendicular to the first direction, the welding surfaces are used for fixing a solder ball in advance before the electric connector is welded with a substrate, the solder ball is arranged on the surface type welding parts of the pair of signal terminals, and each surface type welding part is welded on the surface of the substrate through a solder ball; and a shielding shell which is provided with two jack-type tail parts which are electrically connected with the through holes of the substrate, wherein the two jack-type tail parts are respectively positioned on two sides of the pair of surface-type welding parts along the first direction. According to the invention, the coplanarity of the signal terminals can be improved, the occupation of the wiring space of the substrate by the signal terminals can be reduced, and the risk of tin cracks of the solder balls can be reduced.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector in which the tin balls welded by the surface-type welding parts of the signal terminals are not prone to tin cracks. 【Background technique】 [0002] A conventional electrical connector includes a plurality of pairs of signal terminals, and the soldering portion of each of the signal terminals is soldered to the surface of the circuit board by solder balls. During use, the soldered portion of the signal terminal of the electrical connector may be rotated or shifted relative to the solder ball by external forces, for example, the electrical connector is subjected to multiple insertions and removals, or the use of During the process, the collision with other objects will easily cause the solder balls of the soldering parts of the signal terminals to crack, resulting in poor contact between the signal terminals and the circuit board, thereby affecting the signal of...
