Abstract

An electrical connector and a method of manufacturing the same are provided. A connecting member is embedded in an insulating body between a side edge of the insulating body and an outer side of a first terminal or a last terminal in a first terminal group, and a gap exists between the connecting member and the first terminal or the last terminal. In other words, the connecting member is not in contact with the first terminal or the last terminal adjacent to the connecting member. Thus, the width of the first terminal or the last terminal is not increased, ensuring the high-frequency transmission rate of the first terminal group, and thereby forming an electrical connector which is capable of facilitating machining without affecting the transmission quality of the terminals, and having a stable structure and high-frequency transmission performance.

Dependent claims

An electrical connector, comprising:

a first terminal group, having a plurality of terminals provided thereon;
and
an insulating body, covering the first terminal group by insert molding, wherein at least one of the terminals on the first terminal group is provided with a first strip connecting portion protruding out of a rear end of the insulating body, a connecting member is provided between a first terminal or a last terminal of the terminals on the first terminal group and a corresponding side edge of the insulating body adjacent thereto, the connecting member and the first terminal group are made of a same material, the connecting member is embedded into the insulating body and has two sides, one of the two sides of the connecting member is exposed to the corresponding side edge of the insulating body, a gap exists between the connecting member and the first terminal or the last terminal on the first terminal group adjacent to the other of the two sides of the connecting member in a lateral direction, and the connecting member has a second strip connecting portion exposed to the corresponding side edge of the insulating body.

A method of manufacturing an electrical connector, comprising:

S1:
providing a metal sheet, and manufacturing a first terminal group and at least one connecting member on the metal sheet by punching and blanking, wherein the connecting member is located at an outer side of a first terminal or a last terminal of a plurality of terminals on the first terminal group, a gap exists between the connecting member and the first terminal or the last terminal on the first terminal group adjacent to the connecting member, two ends of at least one of the terminals on the first terminal group are respectively provided with a pre-breaking portion and a first strip connecting portion, the first strip connecting portion is connected with a first strip, the pre-breaking portion is connected with a strip bridge, the connecting member has a second strip connecting portion and is connected with a second strip, and the strip bridge is connected with the second material strip;
S2:
after placing the first terminal group in a mold cavity and positioning the strip bridge and the second strip, forming an insulating body on the first terminal group and the connecting member by insert molding for a first time, wherein the connecting member is embedded between a corresponding side edge of the insulating body and the first terminal or the last terminal of the terminals on the first terminal group adjacent to the connecting member, the second strip connecting portion is exposed to the side edge of the insulating body, the pre-breaking portion is exposed to a front end of the insulating body, and the first strip connecting portion protrudes out of a rear end of the insulating body;
and
S3:
removing the strip bridge and/or the first strip.
