Although the existing connection device has a simple structure and is easy to use, it still has some disadvantages, specifically:

[0003] a. High production cost: U-shaped clamping terminals are required for clamping or soldering at the joints of multi-branch wires, and then heat shrinkable insulation sleeves are used for protection and connection. In addition, the amount of wires used is also large;

[0005] c. Affects installation efficiency and appearance: After the wiring harness is assembled on the whole machine, each branch needs to be fixed manually with a cable tie, otherwise it will be messy and unsightly;

[0006] Therefore, there is an urgent need for a parallel connection terminal which is low in cost, simple to manufacture and has a beautiful appearance. Utility Model Content

[0010] A further solution of the utility model is that both ends of the fixed sliding plate are respectively plugged with blocking ends, and the blocking ends are fixedly connected to the fixed sliding plate through blocking end fixing wires.

[0011] A further solution of the utility model is that the blocking end is a rubber product.

[0012] A further solution of the utility model is that the external wiring plug-in plate, the conductive rod, the conductive external connector, the conductive connecting ring, the plug-in conductive rod and the conductive tube are all superconducting products.

[0013] A further solution of the utility model is that the conductive connecting ring and the inserted conductive rod are made in one piece.

[0014] A further solution of the utility model is that the conductive connecting ring is connected to two groups of symmetrically distributed plug-in conductive rods.

[0015] A further solution of the utility model is that the fixed terminal and the isolation tube are both insulating products.

[0017] Beneficial effects of the utility model:

[0018] 1. The utility model reduces the production cost: eliminates materials such as U-shaped clamping terminals, solder, heat shrink tubes, and reduces the amount of wires used.

[0019] 2. The utility model is relatively simple to manufacture: the work of clamping, soldering and heat-bake shrink tube is eliminated, and only needs to be tightened and rotated.

[0020] 3. The utility model has high installation efficiency and beautiful appearance: after the wiring harness is assembled on the whole machine, each branch does not need to be fixed manually with a cable tie, so the installation efficiency of the whole machine is improved. At the same time, the hand-in-hand parallel connection method is also more beautiful and simple as a whole. BRIEF DESCRIPTION OF THE DRAWINGS
