Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of connectors, and particularly relates to a floating waterproof copper bar connector. BACKGROUND

[0002] As a key component for realizing current conduction between a copper bar and a device, the copper bar connector has a wide application in power distribution, power transmission and various industrial electrical devices. With the increasing requirements of reliability, safety and environmental adaptability of electrical systems in industrial production, the performance of the copper bar connector also faces higher challenges.

[0003] In the prior art, the Phoenix ES-BBC-5-5 BK connector product is a typical representative. From the structural composition, it is usually divided into two independent parts of a mounting frame and a connector body. In the actual application scenario, the customer needs to separately purchase the two parts first, and then perform the installation operation: first install the frame, and then insert the connector into the frame after the frame is fixed. In addition, a floating part is arranged inside the connector body, and a screw spring is provided on the floating part. The original design intention is that when the user pushes the case in, the floating part inside the connector body can automatically adjust according to the actual position of the copper bar, so as to meet the requirement of smoothly conducting the electrical energy to and from the copper bar.

[0004] However, the prior art still has the following more prominent defects: first, the number of parts is too large. The large number of parts not only increases the difficulty of material control in the manufacturing process, but also increases the complexity of the production process, thereby increasing the overall cost. In addition, the large number of parts not only consumes more manpower and time during installation, but also is prone to operation errors during installation, which affects the installation accuracy of the connector and thus affects the subsequent use performance. In addition, the large number of parts is also more prone to defects of poor sealing between the parts, which affects the electrical performance and service life of the connector, and is difficult to adapt to application scenarios with higher protection requirements. Secondly, the screw spring is used inside the connector. The current-carrying capacity of the screw spring is limited, and a large current passing through the screw spring is prone to generate a large resistance and heat, which not only reduces the transmission efficiency of the electrical energy, but also may cause safety hazards due to overheating.

[0005] The information disclosed in this BACKGROUND section is only for the purpose of increasing the understanding of the background of the present application and should not be regarded as an acknowledgment or any form of suggestion that it forms prior art of this application. SUMMARY
