Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a technical solution: the utility model provides a combination formula terminal strip, including binding post 1 and locking mechanism 7, binding post 1's outer wall both ends have all welded fixed block 2, and fixed block 2's inner wall screw connection has dead lever 3, be threaded connection between dead lever 3 and the fixed block 2, and fixed lever 3's outer wall and fixed block 2's inner wall are the heliciform setting, binding post 1's top has been seted up wiring groove 4, and the top laminating of wiring groove 4 has dust plug 5, the bottom of dust plug 5 closely laminates with wiring groove 4's top, and dust plug 5's size and wiring groove 4's size coincide, through the dust plug 5 that sets up, so be convenient for in the use, can pack into the unused wiring groove 4 with dust plug 5, thereby provide dustproof effect to unused wiring groove 4, avoid outside dust to fall into wiring groove 4, lead to producing the bad condition of contact when using subsequently;
