[0017] Example 1, refer to Figures 1-5 A kind of waterproof terminal of not through wall, including main body shell 6, it is characterized in that, the left side of main body shell 6 is vertically fixed with bolt 1, bolt 1 is nested with conductive sheet 2 outside, the upper of conductive sheet 2 is fixed with rivet nut 3, rivet nut 3 is fixed with nylon pressure cap 4 outside, the inside bottom end of bolt 1 is embedded with nylon pressure column 5, the right side of conductive sheet 2 is fixed with crimping terminal 7 by screw, crimping terminal 7 is fixedly connected with cable 9 right side, cable 9 is nested with heat shrink sleeve 8 outside.

[0018] The left and right ends of cable 9 are nested with heat shrink sleeve 8, and the inner sides of the two heat shrink sleeves 8 are crimped with crimping terminals 7;

[0019] When heat shrink sleeve 8 is sleeved on the outer side of crimping terminal 7 and heated, the left and right ends of cable 9 form an insulation layer due to the heat shrinkage of heat shrink sleeve 8, preventing the occurrence of leakage and short circuit at the action end of cable 9, effectively ensuring the safety of personnel and the stability of equipment operation;

[0020] Cable 9, crimp terminal 7 and heat shrink tubing 8 can be combined to form a wire harness. Since the wire harness is fastened to the right side of the main housing 6 by screws and closely attached to the conductive sheet 2, if the wire harness fails later, the faulty wire harness can be quickly replaced by removing the screws, without scrapping the entire product, reducing the cost after failure and making disassembly more convenient.

[0021] Example 2 differs from Example 1 in that, in this example, the right side of the conductive sheet 2 is injection molded into the left side of the main body shell 6 by injection molding.

[0022] When the conductive sheet 2 is injection molded inside the left side of the main body shell 6, it can better ensure the airtightness of the device, thereby reducing the failure rate during the use of the device;

[0023] The nylon pressure post 5 is pressed and embedded in the hole below the bolt 1 by an interference fit. The bolt 1 is embedded in the left side of the conductive sheet 2.

[0024] The main function of the nylon pressure column 5 is to isolate the bolt 1 from the outside when the mold ejector pin is ejected.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
