Abstract: A connecting box for connecting to a solar panel includes a housing and a terminal assembly. The housing has an opening for introducing an electrical connecting element of the solar panel. The terminal assembly is disposed in the housing, which includes a first terminal having a first contact portion for contacting and applying an elastic force to the electrical connecting element and a first releasing portion extending from the first contact portion. The first releasing portion is non-obstructedly arranged in the housing to be operable to release the elastic force without assistance of any tools when the solar panel is inserted into or extracted from the connecting box.

Abstract: A power connector, includes an insulating housing having a plurality of contact receiving passages, each of said plurality of contact receiving passages receives a contact pair having a pair of independent conductive contacts, wherein said independent conductive contact includes a first part made of high conductive material and a second part made of high mechanical material, said first part is connected with said second part by a positioning element, said supporting portion of said second part keeps said first part from over deforming when a force is applied on said contacting portion for power transmission, so as to ensure the stability of power transmission.

Abstract: The present invention relates to a power connector. The power connector includes a housing and a number of contacts received in the housing. At least one of the contacts includes a pair of opposite walls spaced apart at a predetermined distance. The walls have a front end respectively. The contact may further include a contact protection mechanism for protecting the contacts, wherein the contact protection mechanism bridges the front ends of the walls. The present invention also relates to a power connector assembly.

Abstract: A power connector assembly is provided which comprises a plug connector and a mating receptacle connector. The plug connector includes an insulative plug housing having a plurality of passageways divided by division walls and a plurality of plug terminals accommodated in the corresponding passageways of the plug housing. The receptacle connector includes an insulative receptacle housing having a receiving space for receiving a part of the plug housing inserted therein and a plurality of receptacle terminals accommodated in the receptacle housing for mating with the plug terminals. Airflow channels are formed between the outer surface of the part of the plug housing in the receiving space and the inner surface of the receiving space for dissipation of heat.
