摘要： A plug connector is used to be inserted into a socket connector. The plug connector includes: an insulating body, including a main body portion and a locking arm extending from the main body portion; and at least one mating terminal provided in the insulating body. Two locking portions are formed by laterally protruding from left and right sides of the locking arm. Each locking portion is used to be locked with a clip portion of the socket connector, and is located in front of a connecting location of the locking arm and the main body portion. A pressing portion is formed between the two locking portions by protruding upward from the locking arm, and aligning with the locking portions in a left-right direction. The at least one mating terminal is provided with at least one mating portion to mate with at least one conductive terminal of the socket connector.

A latch portion is protrudingly provided above the casing. The first connector includes a shell. A locking arm is pivoted to the shell by a pivoting portion, and is provided with a buckling portion for buckling the latch portion. The locking arm includes at least one first position limiting portion and a second position limiting portion in front of the buckling portion. In a separation process of the first and second connectors, the locking arm is actuated, the buckling portion is detached from the latch portion and moves backward, and the latch portion firstly stops the first position limiting portion. After the latch portion is detached from the first position limiting portion, the latch portion stops the second position limiting portion from moving backward.

摘要： An electrical connector includes an insulating body having a mating slot and multiple accommodating slots are in communication with the mating slot. Multiple terminals are accommodated in the accommodating slots. The terminals include ground terminals. Each terminal includes a connecting portion, an elastic arm, a tail portion, and an extending portion located between the connecting portion and the tail portion. The extending portion of each terminal extends obliquely downward and backward from the connecting portion. A grounding member is provided on the insulating body. The grounding member has a multiple upper and lower extending arms. A length of each upper extending arm is shorter than a length of each lower extending arm in the front-rear direction. The upper and lower extending arms respectively abut the ground terminals, thus shortening the transmission paths of the terminals. The grounding member and the ground terminals are in stable connection, thus reducing the resonance.

摘要： An electrical connector includes multiple terminals formed by cutting from a metal plate and bending. The portion of the metal plate with the terminals being removed is defined as a base plate. Each terminal has a base portion and an elastic arm connected thereto. The base portion is at least partially horizontally provided to be coplanar to the base plate. A cutting slot is formed between the base plate and the base portion. A through slot is formed between the base plate and the elastic arm. An insulating body is provided with through holes running vertically therethrough. A portion of the cutting slot and the through slot are exposed in a corresponding through hole.

摘要： An electrical connector includes an insulating seat and at least one conductive terminal provided therein. The insulating seat includes a rear wall and two side walls, surroundingly forming a mating space. Each side wall includes an extending arm and an elastic arm. The elastic arm has a first arm extending forward from the extending arm and a second arm bending reversely from the first arm and extending backward. The second arm is connected to the rear wall. An opening slot is formed between the first arm and the extending arm and runs forward therethrough. A through slot is formed between the second arm and the first arm. A buckling portion is formed at a side of the second arm away from the first arm to correspond to the through slot and the opening slot in a left-right direction. The conductive terminal has a contact portion exposed to the mating space.
