Description
Technical field
The utility model belongs to sleeve technology field, and more particularly to a kind of casing tube for capacitor stud members polygon is prevented
Revolve structure.
Background technology
Refer to shown in Fig. 1, existing conduit connection post part：Binding post 1, sealing gasket 5, flange 2, sleeve pipe porcelain piece 3, copper twist
Line 4 (through hole binding post is free of copper stranded conductor).
The function of conduit connection post part：A, the extraneous sealing with inside cannula tip of cannula tip is realized；B, set is realized
Loosening, rotation and relative rotation between tube top parts.
The existing head of sleeve pipe porcelain piece 3 is circle, and the head periphery of sleeve pipe porcelain piece 3 sets 3 necks, and the side of flange 2 sets three
Individual concave point 6, and epoxide-resin glue filling need to be smeared in the neck of sleeve pipe porcelain piece 3, realize between flange 2 and sleeve pipe porcelain piece 3
Anti- rotation structure.The top of sleeve pipe porcelain piece 3 is lined with sealing gasket 5, and binding post 1 is fixed on the head of sleeve pipe porcelain piece 3 by flange 2；Flange 2
The anti-rotation structure to cooperate is provided between binding post 1, the rotation of binding post 1 can be prevented.
Existing flange 2 and the fit structure of sleeve pipe porcelain piece 3 have following technical problem：
1 torsional property is poor：3 concave points 6 are stuck in the head neck of sleeve pipe porcelain piece 3 on flange 2, and 3 contact points transmit torsion,
Contact point contacts for point, and the pressure born is big.
2nd, riveting process is poor：Riveting face is small, and porcelain facing is easily scratched in process, and difficulty of processing is higher.
3rd, flange riveting mouth poor appearance：Three necks of sleeve pipe porcelain piece 3 are vertical cular arc groove, after riveting at three grooves
Flange port it is jagged, introduced contaminants is easily hidden in groove during later stage use.
4th, poor reliability：A, three notch, neck are unfavorable for grinding, it is necessary to fill epoxide-resin glue in groove, prevented
Flange concave point is relative in porcelain piece neck to be slided.Due to scribbling epoxide-resin glue in the neck of bushing head, scene goes out in use
The epoxide-resin glue now crossed in indivedual bushing slots is not fully cured, has flowed on the umbrella cover of sleeve pipe, influences the outward appearance of product and close
Feng Xing.B, application moment of torsion lack of standardization during use, easy torsional fracture porcelain piece head.As long as three necks on porcelain piece head have one
Neck ftractures or damage, and it is unbalance to destroy the torsional property of cannula tip structure, causes seal failure.

On flange erecting bed at the top of sleeve pipe porcelain piece；The upper binding post of binding post passes through polygonal through hole, polygonal through hole and binding post
The multi-party boss of anti-rotation cooperate, prevent binding post from being rotated relative to anti-rotation structure flanges；It is anti-to revolve the multi-party convex of structure flanges
For platform jacket casing on the multi-party boss at the top of corresponding round platform portion, circular cylinder portion is enclosed on round platform portion periphery；Circular cylinder portion is riveted on circle
In platform portion.
Further, it is provided between the multi-party boss of middle part anti-rotation of the multi-party boss and binding post at the top of sleeve pipe porcelain piece
Sealing gasket.
Further, it is connected with copper stranded conductor on lower binding post.
Further, it is multi-party boss at the top of round platform portion；The multi-party boss cylinder is six sides being engaged with six side's boss
Boss cylinder.
Further, the multi-party boss of anti-rotation in the middle part of binding post is the side of anti-rotation six；Polygonal through hole is to match somebody with somebody with the side of anti-rotation six
The hexagon through hole of conjunction.
Further, the binding post is process by copper material.
Relative to prior art, the utility model has the advantages that：
1st, with money product, effective sealing area 874mm of prior art sleeve stud members2, the utility model is effective
Sealing area 1326mm2。
2nd, the head of sleeve pipe porcelain piece 3 six side's boss of setting (or multi-party boss), six fang platform cylinders of head flanges top setting (or it is more
Square boss cylinder), realize the relative anti-rotation between flange and porcelain piece；Filled without epoxide-resin glue glue.
3rd, six square tubes on flange (or more square tubes) are enclosed on six side's boss (or multi-party boss) on porcelain piece head, 6 sides
Torsion is transmitted in side face (multiple edge surfaces), and the pressure that contact surface is born is small, and the torsion that the structure is born is much larger than prior art knot
The torsion of the point transmission of structure 3.
4th, it is big to rivet face, is not easy to scratch porcelain facing in riveting process, quite produces.
5th, the side of porcelain piece head six or multi-party boss later stage grinding size are consistent, and flange uses mould punching accurate to dimension
Height, flange and porcelain piece fit-up gap are uniform, uniform force, and lifting surface area is big, and the pressure that torsion is reflected in porcelain piece is small, porcelain piece
Stress point probability of damage is small；
6th, six sides of cannula tip or more square structures have six or multiple stress surfaces for bearing moment of torsion, and a such as stress surface is broken
Bad or failure, the balance for still having no less than 3 stress surfaces to remain torsional property, will not destroy the sealing of conduit connection post part
Effect.
7th, conduit connection post part assembling need not use epoxide-resin glue, and the later stage is without epoxide-resin glue outer-flowing phenomenon.
