Description

High power power connector

This creation is about electrical connectors, especially a high power power connector.

The main function of the electrical connector is to provide connections between various electronic devices or devices, and to ensure that signals between the two can be accurately transmitted. Moreover, the power connector method applied in a general power supply circuit inserts a plug (such as a copper shaft cable structure) into a power socket.

The conventional plug structure is provided with a plate-shaped terminal group in the abutting portion and has a tuning fork-shaped contact portion in front of the terminal group; on the other hand, a plurality of claw-shaped elastic pieces are arranged in the abutting portion of the power socket to The plugs are guided to each other. However, when the plug and the power socket are inserted into each other, the two contacts are in point contact only with the claw-shaped elastic piece at the tuning fork-shaped contact portion. However, such a point contact condition tends to generate heat when the current is large, and the resistance rises, so that the insulating body of the plug and the power socket needs to be made of a material having good heat resistance, thereby causing a substantial increase in the cost of the power connector.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

One of the aims of the present invention is to provide a high-power power connector so that the power connector does not cause an increase in resistance due to a single point contact during the conduction, and excessive excessive temperature can be avoided.

In order to achieve the above purpose, the present invention is a high power power connector, and the plug structure includes a first insulating body, a first conductive sheet, a first conductive terminal and a crown member. The first insulative housing is a pole, the pole has a first receiving space and a first insertion opening and a first through-opening connected to the first receiving space; the first conductive piece is a ring piece, and the ring is sleeved An outer peripheral surface of the pole; the first guiding terminal is disposed in the first receiving space, one end of the first guiding terminal has a mounting groove communicating with the first insertion opening, and the other end protrudes from the first through opening; the crown spring The piece is fixed in the mounting groove and is in contact with the first guiding terminal.

Compared with the prior art, in the plug structure of the high-power power connector of the present invention, the first guiding terminal is a pole, and the first guiding terminal is provided with a crown member; and the first conductive piece is a ring piece. And the ring is sleeved on the outer peripheral surface of the pole; on the other hand, the second conductive piece of the socket structure is also disposed as a ring piece, according to which, when the plug and the socket are mutually connected, the first conductive piece and the second conductive piece are The contact between the crown spring member and the second lead terminal is also in the form of a ring-shaped multi-point contact, whereby the power connectors are not connected to each other when they are connected to each other. The contact resistance causes the resistance to rise, which avoids excessive high temperature. Therefore, the insulator does not need to use a high temperature resistant material and does not increase the cost of the power connector, thereby increasing the practicality of the creation.
