Description

Technical Field

[0001] The fully independent connector of the present invention belongs to the field of power distribution equipment. Background Art

[0002] A connector is a connecting terminal for connecting two busbar copper bars, which is an important electrical component to ensure the stable connection of busbar copper bars and electrical safety. It is widely used in the current power distribution field.

[0003] Existing connectors generally include multiple pairs of connecting copper bars threaded on a bolt and insulating partitions separated between each pair of connecting copper bars. Due to processing technology limitations, there are differences in the connecting copper bars in this type of connector. At the same time, the pressures on each connecting copper bar and insulating partition are different during the assembly process, resulting in the connecting copper bar being distorted under pressure or having poor butt joint with the busbar copper bar during the installation process, leading to poor contact between the connecting copper bar and the busbar copper bar. In a power distribution system using busbar copper bars, the voltage and current are generally high. Once the contact is poor, it is extremely easy to cause a power grid outage or serious heating of the connector.

[0004] In addition, the current connector is not easy to install, and has high proficiency and precision requirements for on-site installers, which is not conducive to rapid, efficient and high-quality on-site operations. Summary of the Invention

[0005] To solve the above technical problems, the present invention proposes a fully independent connector that can be quickly plugged in and has good and stable contact.

[0006] To achieve the above technical purpose, the technical solution provided by the present invention is as follows:

[0007] The fully independent connector includes a connector base. The connector base includes a plurality of copper bar interfaces. The copper bar interface includes a joint insulator, and the joint insulator is a square groove structure as a whole. One end of the copper bar interface is a direct copper bar interface, and the other end of the copper bar interface is provided with a copper bar extension interface. A plurality of the copper bar interfaces are fixedly arranged in parallel, and the ends of adjacent copper bar interfaces are installed with a dislocation.

[0008] The direct copper bar interface includes two copper inserts and a spring piece arranged in the joint insulator. Spring pieces are arranged between each copper insert and the inner side wall of the joint insulator.

[0009] Raised pressing blocks are arranged on both inner side walls of the joint insulator. An arc groove adapted to the raised pressing blocks is arranged in the middle of the spring piece. The two ends of the spring piece are closely attached to the copper inserts, and the two spring pieces press and fit the two copper inserts tightly.

[0010] The direct copper bar interface of the copper bar interface is arranged in parallel with the copper bar extension interface of its adjacent copper bar interface, and the copper bar extension interface of the copper bar interface is arranged in parallel with the direct copper bar interface of its adjacent copper bar interface.

[0011] The direct copper bar interface is inserted into the busbar copper bar on one side, and the busbar copper bar on the other side passes through the copper bar extension interface and is inserted into the direct copper bar interface.

[0012] The width of the copper bar extension interface is smaller than that of the direct copper bar interface.

[0013] The copper plug-in is of a plate structure, and the plate surfaces of the two copper plug-ins are both attached to the spring piece.

[0014] A raised contact point is provided on the side of the copper plug-in away from the spring piece, and the raised contact points on the two copper plug-ins are correspondingly attached.

[0015] The two ends of the copper plug-in cooperate with the inner side wall of the joint insulator. The two copper plug-ins can move relative to each other with their plate surfaces facing each other, and the two copper plug-ins are relatively fixed in the extending direction of the plate surface.

[0016] The completely independent joint device further includes a joint device cover. The joint device cover is fixed above the joint device base, and the joint device cover completely covers the electrical components of the joint device base.

[0017] The joint insulator and the joint device cover are made of DMC material.

[0018] The present invention has the following beneficial effects compared with the prior art:

[0019] 1. The present invention uses copper plug-ins and spring pieces to realize the plug-in connection of the busbar copper bars, avoiding the problem of poor contact between the wiring copper bar and the busbar copper bar during the installation of the joint device. At the same time, this method has the advantages of simple installation and use and stable installation quality.

[0020] 2. The plug-in wiring method of the busbar copper bar leads to an increase in the volume of the copper bar interface. At the same time, to ensure electrical safety, the wall thickness of the joint insulator should be greater than the size specified by the electrical safety regulations. At the same time, to ensure the smooth installation of the joint device in the electrical field such as electrical cabinets, the overall width of the joint device cannot be changed; therefore, the present invention adopts the misaligned installation of the ends of adjacent copper bar interfaces, so as to meet the requirements of the increased volume of the copper bar interface and electrical safety while ensuring that the overall width of the joint device will not increase.

[0021] 3. The raised contact points are provided on the copper plug-ins of the present invention. On the one hand, it is convenient for the busbar copper bar to be inserted into the copper bar interface, and on the other hand, it ensures good contact between the busbar copper bar and the copper plug-in.

[0022] 4. The present invention uses spring pieces to ensure that the two copper plug-ins are always in a compressed state, ensuring good contact between the busbar copper bar and the copper plug-in. BRIEF DESCRIPTION OF THE DRAWINGS
