Electric connector

Abstract

Provided is an electric connector, which is used for butt joint with a cable. The cable has a core. The electric connector is characterized in that the electric connector comprises an insulation bodyhaving a plurality of accommodating grooves, and each accommodating groove is provided with a first inclined surface and a second inclined surface, which are connected to each other, forming a intersecting line, and the first inclined surface and the second inclined surface are respectively disposed at two corresponding sides of the vertical plane; the electric connector comprises a plurality of signal terminals, which are respectively provided with a contact part; the plurality of contact parts of the multiple signal terminals are arranged in a row along the horizontal direction; the contactpart is provided with a butt joint face for connecting to the core in the manner of laser welding, and a first surface opposite to the butt joint face, and a second surface connected to the butt jointface and the first face. The invention is advantageous in that the first surface is in parallel with and contacts with the first inclined surface, and the second surface is in parallel with and contacts with the second inclined surface, and thereby the contact part is disposed in the accommodating groove in an inclined manner; the laser is reflected downwardly to the contact part of the core andthe butt joint surface by the butt joint surface, and thereby the laser energy can be well focused.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector used for laser welding with cables. Background technique [0002] In an existing electrical connector, the terminal has a vertically arranged contact portion, the wire core of the cable abuts against the side of the contact portion, and the laser irradiates the contact portion between the contact portion and the wire core vertically from above, so that the contact portion and the wire core Laser welding of the wire core, since the contact part of the wire core and the contact part is exposed upward, it is convenient to check the welding effect. However, since the contact portion between the contact portion and the wire core has a very small range along the horizontal direction, the precision of laser welding is very high. , It will cause insufficient heating of the contact part and the contact part of the wire core, resulting in unstable welding, false welding a...
