Industrial connector
Technical field
The utility model relates to a kind of industrial connector.
Background technology
Existing industrial connector is the box body that comprises base and sheath, base is used to hold plug pin, sheath is used to surround plug pin and the contacting that is connected lead-in wire, can reverse relatively mutually between these two parts to constitute and removably connect, wherein an end that is connected with sheath relatively on the base forms terminals, terminals are by link cover of FIG, sleeve and a plurality of binding post are formed, a plurality of binding posts are parallel to each other and clocklike arrange along the periphery in the base center of circle, each binding post is arranged with the plastics sleeve outward, the flat shape that the global shape of link cover of FIG and a plurality of binding post permutation and combination form is suitable, and corresponding binding post forms a plurality of connection lead hole on the link cover of FIG, and link cover of FIG covers on the upper surface of a plurality of sleeves.When the assembling bottom, dead between link cover of FIG and the sleeve with supersonic welding, can't dismantle, if binding post damages, be not easy to change.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of industrial connector of being convenient to change binding post is provided.
For achieving the above object, the utility model adopts a kind of industrial connector, comprise the box body of base and sheath at least, base is used to hold plug pin, sheath is used to surround plug pin and the contacting that is connected lead-in wire, can reverse relatively mutually between these two parts to constitute and removably connect, wherein an end that is connected with sheath relatively on the base forms terminals, terminals are by link cover of FIG, sleeve and a plurality of binding post are formed, a plurality of binding posts are parallel to each other and clocklike arrange along the periphery in the base center of circle, each binding post is arranged with the plastics sleeve outward, corresponding binding post forms a plurality of connection lead hole on the link cover of FIG, link cover of FIG covers on the upper surface of a plurality of sleeves, corresponding binding post one side forms the screw hole column parallel with binding post vertically on the base, form on the link cover of FIG and the suitable screw hole of screw hole column, link cover of FIG by screw on screw hole column.
In order to realize optimum design, make the total compactness, the utility model further is set to the outer that 2 screw hole columns are symmetricly set on the both sides of a plurality of binding posts, and link cover of FIG is shaped as column type, inner formation and the suitable cavity of sleeve, screw hole place the edge of column type.
For the lid of link better, the utility model line end one side direction center of circle direction that further is set to connect on the inwall of base extends to form the flange of annular, and the bottom surface of link cover of FIG is pressed on this flange.
The utility model is realized being screwed connection between link cover of FIG and the sleeve by the terminal structure in the industrial connector of prior art is improved, if binding post damages, can take off link cover of FIG as long as turn on screw, the replacing of the terminal that conveniently achieves a butt joint.

Embodiment
As Fig. 1,2, shown in 3, specific embodiment of the utility model is a kind of industrial connector, comprise the box body of base 1 and sheath 2 at least, base 1 is used to hold 3 plug pins, sheath 2 is used to surround plug pin and the contacting that is connected lead-in wire, can reverse relatively mutually between these two parts to constitute and removably connect, wherein an end that is connected with sheath 2 relatively on the base 1 forms terminals, terminals are by link cover of FIG 11, sleeve 12 and 3 binding posts 13 are formed, 3 binding posts 13 are parallel to each other and clocklike arrange along the periphery in base 1 center of circle and constitute an equilateral triangle, each binding post 13 outer plastics sleeve 12 that are arranged with, corresponding binding post 13 1 sides form the screw hole column 14 parallel with 2 binding posts 13 vertically on the base 1,2 screw hole columns 14 lay respectively on the sideline of the equilateral triangle that 3 binding posts 13 constitute and are symmetrical arranged, link cover of FIG 11 is shaped as column type, it is inner to form the cavity suitable with sleeve 12, corresponding binding post 13 forms 3 connection lead hole 111 and 2 screw holes 112 on the link cover of FIG 11, screw hole 112 places the edge of column type, the line end one side direction center of circle direction that connects on the inwall of base 1 extends to form the flange 14 of annular, the bottom surface of link cover of FIG 11 is pressed on this flange 14, the inner chamber of link cover of FIG 11 then covers on the upper surface of 3 sleeves 12, and link cover of FIG 11 is fixed on the screw hole column 14 by screw 15.
The base 1 of the industrial connector of the foregoing description is used to hold 3 plug pins, the structure of link cover of FIG 11 wherein and be equally applicable to have the industrial connector of the plug pin of different numbers with the connected mode of screw hole column 14.
