Electrical connector assembly

Abstract

An electrical connector assembly is disclosed, which includes plug connector having a first body and first terminals accommodated therein, and a socket connector. A slot is arranged between the two first terminals, each first terminal has a first contact arm and a second contact arm which are oppositely arranged, each of the first contact arm and the second contact arm is provided with first, second, third, and fourth contact parts, and a fifth contact part is further provided behind the second contact portion. The socket connector has a second body and second terminals accommodated therein, abarrier stretches from one side of the second body to between the two second terminals, when the plug connector is in a butt joint with the socket connector, the barrier is matched with the slot, andthe second terminals are first in contact with the first, second, third and fourth contact parts, and is in contact with the fifth contact part in the process of further insertion, thereby ensuring the correct butt joint of the plug connector and the socket connector, and the first terminal and the second terminal are in stable contact and not easy to fall off.

Description

technical field [0001] The invention relates to an electrical connector combination, in particular to an electrical connector combination which has a good heat dissipation effect and can ensure correct insertion of butt connectors and stable contact. Background technique [0002] A known power connector combination, the plug connector includes a first body and a first terminal accommodated in the first body, the socket connector includes a second body and a second terminal accommodated in the second body, the second body There is a partition that separates each second terminal and completely closes it. In order to guide the correct insertion of the plug connector, a narrow slot is usually opened on the partition of the socket connector or in the second body receiving cavity. The edge is chamfered, and the corresponding ridges and chamfers are set on the plug connector to match the narrow groove. However, the power connector usually carries a relatively large current or power...

[0002] A known power connector combination, the plug connector includes a first body and a first terminal accommodated in the first body, the socket connector includes a second body and a second terminal accommodated in the second body, the second body There is a partition that separates each second terminal and completely closes it. In order to guide the correct insertion of the plug connector, a narrow slot is usually opened on the partition of the socket connector or in the second body receiving cavity. The edge is chamfered, and the corresponding ridges and chamfers are set on the plug connector to match the narrow groove. However, the power connector usually carries a relatively large current or power, which will generate considerable heat during use. The conventional design above can only achieve foolproofing but does not solve the heat dissipation problem of the power connector

At the same time, the first terminal of the plug connector usually has a pair of interfaces and a main body, and the opposite sides of the main body respectively extend an elastic arm to the direction of the interface for docking with the second terminal. However, since each elastic arm has only One contact part, so it can only be in contact with the two surfaces of the second terminal, so the stable contact between the first terminal and the second terminal cannot be guaranteed during the docking process, which will easily affect the function of the connector; in addition, because the contact part is only It is located near the mating port, but no elastic contact part is provided at the rear of the mating port close to the direction of the main body, so it cannot provide sufficient insertion force during the mating process of the connector, which may easily lead to falling off during use and affect the use effect
