DETAILED DESCRIPTION

[0014] The following will be combined Figs. 1-3 , the content of the utility model is explained in detail through specific embodiment. EMBODIMENT

[0015] The terminal structure of the compressor, including terminal body, the insulating protective shell 8 of the terminal body outside, its technique: the front end of terminal body is provided with joint part 1, is used for inserting the binding post, and is connected with the outside and driver;The left and right sides symmetrical setting has buckle part 2 in the rear end of joint part, the buckle part of symmetrical setting presents eight character shape, and the buckle part is used for connecting with the insulating protective shell, and the buckle part is elastic component, after inserting the insulating protective shell of terminal, the buckle part pops out from notched structure 9, and is limited;The reinforcing groove 3 is provided with in the connecting place of buckle part and joint part, this strong groove is used to increase the elasticity of buckle, makes the buckle more easily pop out, and strengthens the strength, reduces the risk of loosening and falling off of protective shell installation;The lower part of joint part is provided with flat plate part 4;The left and right sides symmetrical setting has pressing plate part 5, pressure connection part one 6 and pressure connection part two 7 in the terminal body;The pressing plate part is pressed in the top of flat plate part;The notched structure for the buckle part joint is provided on the insulating protective shell, and the notched structure is used for the buckle part joint limit.Pressure connection part one, for the resistance welding connection of terminal body and copper wire, makes the current conduction;Pressure connection part two, for fixing the copper wire insulation sleeve outside the copper wire of terminal body.
