Wiring terminal
The utility model relates to a kind of power supply wiring jockey, and particularly a kind of usefulness is ended the Wiring terminal that tight screw ends stressed joint the end of a thread.
As everyone knows, usually the power supply wiring jockey adopts wire head welding or crimping plain film terminal mostly, again terminal is enclosed within on the connection bolt, shimming nut compressing then, this type of binding post is cylindrical structural mostly, as locks not enough or change collision and meet accident because of vibrations make loosening bad connection or the strand of taking place of conductor terminal.And wire head is not used instrument with the method for welding or crimping plain film terminal when daily use, very inconvenient.
In order to overcome above-mentioned shortcoming, the purpose of this utility model provide a kind of manufacturing process simple, connect convenient, the reliable binding post loosening, that rotate that is difficult for again.
In order to realize the foregoing invention purpose, a kind of wiring that the utility model provides leans on by pedestal, end tight bolt forms, and pedestal has radially a screw and an axial hole, and this ends tight bolt and this, and radially screw and pedestal link by screw thread.
In order further to realize the foregoing invention purpose, the pedestal that above-mentioned wiring is leant on is made up of insulation crust and conductive attachment main body; This insulation crust and conductive attachment main body are injected into one.
In order further to realize the foregoing invention purpose, insulation crust one end of the pedestal that above-mentioned wiring is leant on is cylindrical, and the other end is square (body).
A kind of wiring of adopting the utility model to provide is leant on, and compresses by ending tight bolt owing to enter the lead of pedestal, thereby connects connecting not only reliably but also being difficult for loosening or rotation of convenient, lead and conductive attachment main body.
Engaging accompanying drawing and specific embodiment below is explained in detail the utility model.
The sectional structure chart of the binding post of the embodiment that Fig. 1 provides for the utility model.
Fig. 2 cuts open the square cutaway view in position for the AA of the binding post of the described embodiment of Fig. 1.
Fig. 3 is the schematic diagram of chucking shell fragment.
With reference to Fig. 1, a kind of wiring that the utility model provides leans on by pedestal (14), end tight bolt (2) forms.The pedestal that above-mentioned wiring is leant on (14) is made up of insulation crust (1) and conductive attachment main body (4), and this insulation crust and conductive attachment main body are injected into one; Insulation crust (1) and conductive attachment main body (4) respectively have a screw radially, and conductive attachment main body (4) has an axial hole. and this ends tight bolt (2), and radially screw and insulation crust (1) and conductive attachment main body (4) link by screw thread by this.External wire (10) can link together with conductive attachment main body (4) by hold-down bolt (6) and elastic washer (5) thereof.Chucking shell fragment (3) inserts in the casing insulation material square position groove C.Connecting main body (4) is electric conductor, usually by electric conductivity good metal made. insulation crust (1) is an insulator, make by insulating material. connect main body (4) and be combined into one with insulation crust (1). when external wire (7) need be when this electrical equipment connects, in case external wire (7) enters in the axial hole of conductive attachment main body (4), screw with screwdriver and to end tight bolt (2), this ends tight bolt (2) and will move down, near lead (7), thereby compress this lead, easy to use quick.
Referring to Fig. 2, an end of insulation crust (1) is cylindrical, and the other end is square.A kind of wiring that this square shell end can make the utility model provide is leant in the square hole that inserts easily on the various casing for electric appliances.
Referring to Fig. 3, above-mentioned chucking shell fragment (3) radially has certain elasticity, axial width also has certain elasticity in addition, and in chucking shell fragment (3) inserted the square position of casing insulation material groove, just the binding post that the utility model can be provided reliablely and stablely was fixed on the casing for electric appliances.
Certainly, when stating the invention order in realization, the insulation crust (1) of the pedestal that wiring is leant on (14) and the shape of conductive attachment main body (4) can be not limited to the shape of the foregoing description; This insulation crust (1) and conductive attachment main body (4) can and for example be glued together, rivet or be used spiral marking connection by variety of way.But this conversion is all in protection range of the present utility model.
