Background
When the common standard Coo l Edge Connector product is required to have high current (50A), at least 2-3 pairs of power pins are needed, the current passing through each pair of power pins is 10A-30A, the space for installing the power pins is reserved on the connector, and a large amount of space for installing the communication pins is reserved, so that the volume ratio of the existing connector is larger, and the miniaturization trend of the existing electronic equipment is that the Coo l Edge Connector product on the market is difficult to meet the miniaturization requirement.
The Chinese patent literature has publication number CN 205565056U, publication date 2016.09.07 and is entitled to a high current transmission connector, which comprises a clamping plate assembly and a socket assembly which are assembled together; the clamping plate assembly comprises a clamping plate and a guide column electrically connected with the clamping plate; the socket assembly comprises a socket, wherein the socket is provided with mounting holes arranged at two ends of the socket and pins which are arranged in rows between the two mounting holes and are used for carrying out signal transmission in electric connection with the clamping plate; the mounting hole is internally provided with a clamping structure for fixing the guide post on the socket and carrying out current transmission between the clamping plate assembly and the socket assembly. When the guide posts and the clamping structure are fixed together to form a male-female end matched structure, the two guide posts not only play a role in guiding, but also can bear 50A of large current, so that the connector does not need to reserve a large amount of space to install a power needle, the space of the connector is effectively saved, and the miniaturization trend of the connector is met.
However, the above-mentioned patent has a technical disadvantage that the transmission efficiency between the terminals is poor, and the improvement of the design of the contact surface has a large improvement space for improving the transmission efficiency, and the improvement of how to firmly connect the terminals and the main body is also required.
