Embodiment Construction
[0016] like Figure 1 to Figure 5 Shown, the embodiment of the electrical connector of invention, this embodiment is a kind of electrical connector receptacle that has power hole contact 40 and signal contact 50 at the same time, and this electrical connector comprises the rectangular insulating shell of mounting contact 2. The front end 21 of the insulating shell 2 is the plug-in end, the rear end 22 is the mounting end corresponding to the adapter circuit board, the two sides in the length direction of the insulating shell 2 are the left and right sides, and the width direction of the insulating shell 2 is The two sides are a top surface 23 and a bottom surface 24 .
[0017] The power hole contact piece 40 is composed of a pair of contact pieces arranged side by side when in use, and the structure of the two contact pieces is symmetrical to the plane sandwiched between them in use. Since the structures of the two contact pieces are substantially the same except for the symm...

The invention discloses a power supply hole contact part, contact pieces thereof and an electric connector, wherein the electric connector comprises a rectangular insulating housing, a contact part mounting cavity which penetrates through the front end and the back end of the insulating housing and is used for assembling the power supply hole contact part is formed in the insulating housing, the power supply hole contact part comprises two independent split structures and a pair of contact pieces which are arranged at the left and the right at an interval, each contact piece comprises a planar plate which is positioned at the front end and taken as the plug-in connection end, two pairs of guide mounting grooves for front and back guide plug-in fit with the contact pieces are oppositely arranged on the cavity walls of the contact part mounting cavity, which are near to two sides of the top surface and the bottom surface of the insulating housing, the back ends of the guide mounting grooves are open, and the front ends of the guide mounting grooves are sealed. The power supply hole contact part adopts the split type structure, the two contact pieces are simple to manufacture, and have no connection relationship, air flow in the up and down direction between the planar plates of the two contact pieces is not blocked by a bridging part, and the durability and the heat radiation effect of the electric connector adopting the power supply hole contact part can be improved.
Description
technical field [0001] The present invention relates to electrical connectors. Background technique [0002] The two matching electrical connectors carrying large currents in the circuit board transmit current through the mating of the power hole contacts in the electrical connectors. Due to the high passing current, in order to reduce the temperature rise of the contacts, the circuit where the electrical connector is located Therefore, the electrical connector is required to have a good heat dissipation structure, and at the same time, the electrical contact between the socket contact and the plug contact is required to be reliable after mating, and the contact resistance should be as small as possible. However, the two contact pieces of the existing power contacts of this type are a composite structure formed by connecting bridging elements. The way that the components are separated and arranged at a certain interval increases the air permeability, but the manufacturing p...
