Embodiment 1

As Fig. 1,3,4, shown in 5, a kind of T type binding post, comprise case 2, base 10 and thread depressing mechanism, described thread depressing mechanism is with being fixed in the base 10, described case 2 covers on base 10 fixing with hold-down screw 11, have branch line outlet 15 on the described base 10, described case 2 and base 10 two ends respectively have two semicircle mouthful, semicircle mouthful of two ends cooperates the back to form main line import 13 and main line outlet 14, described thread depressing mechanism comprises embedding thing frame 4, housing screw 5, nut 6, main line wire clamp 7 and branch line wire clamp 8, described embedding thing frame 4 usefulness trip bolts 9 are fixed in the base 10, embedding thing frame 4 is the U type, branch line wire clamp 8, main line wire clamp 7 and nut 6 are set in sequence in the embedding thing frame 4 to U type opening from U type bottom, trend with the lead main line serves as axial, described branch line wire clamp 8, main line wire clamp 7 and nut 6 radially slide in embedding thing frame 4, the sliding position of nut 6 is spacing by position limiting structure, have tapped through hole radially on the described nut 6, housing screw 5 is a soket head cap screw, housing screw 5 passes tapped through hole extruding main line wire clamp 7, and main line wire clamp 7 is squeezed back transmission pressure to branch line wire clamp 8.Position limiting structure in the utility model can be specifically described as on the two side of embedding thing frame 4 and have stopper slot, and nut 5 both sides are provided with the slide block that becomes one with it, slide block and the stopper slot sliding position of restriction nut 5 in embedding thing frame that match.

Binding post of the present utility model is in order to improve the sealing property of water proof and dust proof, also all be provided with hermetically-sealed construction at each opening part, hermetically-sealed construction comprises the main line sealing ring, branch line sealing ring 17, spiral cover 12 and sealing gear ring 16, the main line sealing ring is spliced and combined by last sealing ring 31 and lower seal 32 and forms, main line sealing ring both sides are for exporting 14 closed holes that match with main line import 13 and main line, have seal groove on semicircle mouthful of position that case 2 and base 10 contact with each other and case 2 and base 10 two ends, last sealing ring 31 and lower seal 32 are separately positioned in the seal groove on case 2 and the base 10; As shown in Figure 2, described spiral cover 12 is enclosed within the branch line outlet 15, described sealing gear ring 16 is arranged in the branch line outlet 15, be provided with and seal the arcwall face that gear ring 16 matches in the spiral cover 12, the strip tooth bar that sealing gear ring 16 is lined up ring-type by a circle constitutes, the surface of adjacent two tooth bars is the lozenges that matches, certain interval is arranged between the tooth bar, branch line sealing ring 17 is arranged in the sealing gear ring 16 for annular, after putting spiral cover 12, arcwall face can be pushed down tooth bar in the process that spiral cover 12 screws in, and makes tooth bar shrink extruding branch line sealing ring 17 and plays the effect that compresses sealing.For the effect that improves sealing in the present embodiment, have through hole on the described case 2, described through hole is that fluid sealant pours into mouth, fluid sealant pours into mouth and is covered by sealing cap 1, during use earlier by fluid sealant pour into mouthful charge into sealing fluid after, shut fluid sealant by sealing cap 1 and pour into mouth, with the enhanced leaktightness effect.

The utility model can be used on the lead of many different-diameters, if use wide-aperture main line sealing ring will reduce the effect of sealing for the lead that cooperates maximum gauge, so in order in use and to match without the lead of diameter, the closed hole of described main line sealing ring both sides is a truncated cone-shaped, the closed hole of truncated cone-shaped is divided into some annulate lamellas, choose the annulate lamella of cooperation according to the diameter of lead after, outside unnecessary annulate lamella cut out and get final product, can improve the sealing effectiveness of main line sealing ring greatly, very convenient.

When using, opens the utility model case 2, branch line wire clamp 8 is put into embedding thing frame 4, then main line is placed on the base 10, the branch line that branch line is inserted on the base exports in 15, in turn main line wire clamp 7 and nut 6 are put in the embedding thing frame 4 again, screw in housing screw 5, because of the sliding position of nut 6 is subjected to the position limiting structure restriction, so main line wire clamp 7 is along with the continuous extruding of housing screw 5 compresses main line, main line passes to branch line wire clamp 8 to pressure, make branch line wire clamp 8 compress branch line equally, cover case 2 complete operations at last.
