Description

Technical Field

[0001] The utility model relates to the technical field of conductor connection, in particular to a connection device with high connection precision. Background Art

[0002] With the rapid development of my country's national economy, the number of electrical equipment in large and medium-sized cities has increased, and the application of power cables has also entered a rapid development stage. Due to the long urban power supply lines and the large cross-section of the main trunk conductors, the number of connection points of power cable conductors has increased. However, it has also posed new challenges to the cable conductor connection method. The cable connection point is an important part of the power cable and the weak link of the entire cable. Its failure rate accounts for about 60% of the entire cable failure, and most of the cable failures occur at the conductor core connection point. Therefore, the quality of conductor connection has become a major safety issue in the cable power supply system and an important link in the safe power supply of cables;

[0003] A Chinese patent with publication number CN209461706U was searched and disclosed a connecting device of a connector.

[0004] The above technical solution includes a fixing plate, a first spring and a limiting plate. The beneficial effect of the utility model is that by arranging the fixing plate and the first spring behind the first connector, when the limiting plate is inserted into the first limiting groove on the first connector and the knob is turned to a certain extent, the limiting block will press over the reset limiting block, so that the reset limiting block will clamp the limiting plate to prevent it from falling off and moving. Then the first spring will continue to give the first connector an assisting elastic force, thereby strengthening the connection with the second connector. In addition, when it is necessary to connect the first connector and the second connector, the check buckle on the first connector can be directly inserted into the second limiting groove on the second connector to form a card connection. When it is necessary to disassemble the card connection between the first connector and the second connector, the reset block can be directly pressed and then pulled down to make it collide with the check buckle, so that the check buckle can be pushed out of the second limiting groove to cancel the card connection.

[0005] However, in the above scheme, this technology cannot accurately connect multi-channel connectors. Multi-channel connectors require multiple connection points that are not interconnected, so it is not convenient to connect them correctly. The connection method required by this technology is to directly insert the connectors, and many connectors are very precisely designed and require vertical connection to avoid damage to the connectors.

[0006] To this end, we propose a connection device with high connection accuracy. Utility Model Content
