Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, and particularly relates to a large-current wiring terminal for module series connection. Background Art

[0002] Module series connection means connecting multiple modules together in a certain order and manner to achieve specific functions or meet specific performance requirements. As Figure 1 shown, most of the module series connection schemes in the prior art use soft copper bars for connection, and the soft copper bars have a unified and regular shape; in addition, the soft copper bars have a certain expansion and contraction space, so the installation is convenient, fast and beautiful, and it has been widely used. However, at present, the copper price in the market is gradually increasing, resulting in a gradual increase in the price cost of the soft copper bars used for module series connection; at the same time, the soft copper bars cannot be repaired when damaged and can only be replaced as a whole, thus further increasing the use cost. Therefore, there is an urgent need for a wiring component with low use cost and easy to use. Content of the Utility Model

[0003] To achieve the above object, the utility model adopts the following technical means:

[0004] A large-current wiring terminal for module series connection includes a cable, both ends of the cable are respectively connected with large-current terminal crimping components, a movable collar is sleeved outside the cable, one side of the movable collar is connected with a connecting plate, the large-current terminal crimping component includes a large-current terminal pressing plate, a circular hole is opened at one end of the large-current terminal pressing plate, a double-port wire inserting frame is connected to the other end of the large-current terminal pressing plate, the wires at the end of the cable are divided into two groups and respectively inserted into the two sockets of the double-port wire inserting frame, a push rod corresponding to the socket of the double-port wire inserting frame is inserted into the double-port wire inserting frame, a lower pressing plate arranged in the socket of the double-port wire inserting frame is connected to the inserting end of the push rod, a pushing plate is connected to the end of the push rod far away from the double-port wire inserting frame, two groups of symmetrically distributed positioning plates corresponding to the pushing plate are connected to the double-port wire inserting frame, and the pushing plate is connected with the positioning plate through a connecting wire.

[0005] A further scheme of the utility model is that a waist-shaped hole is opened at one end of the large-current terminal pressing plate and is arranged on one side of the circular hole.

[0006] A further scheme of the utility model is that the cable is a soft silicone cable.

[0007] A further scheme of the utility model is that multiple groups of the movable collars are provided, and the multiple groups of movable collars are evenly sleeved outside the cable.

[0008] A further scheme of the utility model is that the movable collar and the connecting plate are integrally made.
