Electrical connector

Abstract

An electrical connector includes an insulating body and a plurality of conductive terminals mounted on the insulating body. The insulating body is provided with an abutment surface abutting an external electrical connector a mounting surface opposite to the abutment surface, a plurality of terminal accommodating grooves penetrating through the abutment surface and the mounting surface along a back and forth direction, a partition wall located between the abutment surface and the mounting surface for positioning the conductive terminals, and a heat sink penetrating through the partition wall and communicating with the terminal accommodating grooves. The conductive terminals are provided with abutment portions extending forward and being accommodated in the terminal accommodating grooves, holding portions positioned on the partition wall and welding portions extending out of the partition wall from the holding portions. The insulating body is further provided with a heat dissipating portion located between the mounting surface and the partition wall. The heat dissipating portion and the heat sink are communicated so as to form a heat convection channel. In this way, the heat dissipating effect of the invention is enhanced.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector mounted on a circuit board. Background technique [0002] At present, many traditional power connectors on the market assemble the conductive terminals from the back to the front, that is, the conductive terminals and the insulating body adopt a hard interference fit. Since the power connector generally has a buckle on the insulating body that matches the mating connector, when plugging and unplugging the mating connector, the mating connector needs to be pressed down against the buckle before it can be pulled out. However, in the process of use, it cannot be guaranteed that each user can first press down the docking connector and then pull out the docking connector. Therefore, in the process of plugging and unplugging the docking connector, especially the vertical power connector, it The insulated body will be separated from the conductive terminal due to a lar...

Problems solved by technology

However, in the process of use, it cannot be guaranteed that each user can first press down the docking connector and then pull out the docking connector. Therefore, in the process of plugging and unplugging the docking connector, especially the vertical power connector, it The insulating body will be separated from the conductive terminal due to a large force, leaving only the conductive terminal on the circuit board, which will affect the performance of the electrical connection with the docking connector

In addition to the above phenomena, the mounting surface of the general power connector is directly attached to the surface of the circuit board, and the heat generated during the use of the conductive terminal may not be dissipated as soon as possible, which will cause the performance of the power connector to be damaged. The increase of the use time will also reduce the transmission performance of the terminal
