Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein includes Any and all combinations of one or more related listed items.

As shown in Figure 1, the integrated retainer 100 of an embodiment includes insulating protective layer 110, the insulating protective layer 110 Including first 111 and second 112.Second 112 one end is fixedly connected with first 111, second 112 other end It is placed in the transformer oil of transformer.First 111 includes ontology 1111 and the first protrusion 1112, and the first protrusion 1112 is from ontology 1111 outer wall extends out to the direction far from ontology 1111 and is formed.It should be noted that the quantity of the first protrusion 1112 It can be one or more.The insulating protective layer 110 offers cavity.The integral type casing in one of the embodiments, Seat 100 further includes copper rod 120, and copper rod 120 is worn in the cavity.

The quantity of the first protrusion 1112 is between the first multiple and adjacent protrusions 1112 in one of the embodiments, There is gap.That is, the longitudinal section of first 111 outer surface of insulating protective layer 100 is serrated.Further, it asks Referring again to Fig. 1, in the present embodiment, first protrusion 1112 is from ontology 1111 close to the ontology of second 112 this part Outer wall extends outward, that is to say, that ontology 1111 includes two parts, wherein the outer wall of the part close to second 112 It is equipped with first protrusion 1112.First 111 integrated molding in one of the embodiments, so that the integral type set The structure of tube socket 100 is simpler.Further, first 111 and second 112 can be integrally formed.It should be noted that First 111 and second 112 can be integrally formed by Shooting Technique etc..Material used by insulating protective layer 100 can be with For epoxy resin etc..Wherein, the shape of the first protrusion 1112 can be annular shape, so that its stress more disperses, improve Intensity.

It refer again to Fig. 1, the outer edge of the separate ontology 1111 of the first protrusion 1112 and the side of second 112 other end It is connected between edge by cambered surface 113, the central angle of the cambered surface 113 is far from ontology 1111.That is, second 112 appearance Face is concave surface, and its appearance is towards the direction indent where the first protrusion 1112.Due to the separate ontology of the first protrusion 1112 It is connected between 1111 outer edge and the edge of second 112 other end by cambered surface 113, so that second 112 Stress distribution is more uniform, and by arc transition between the first protrusion 1112 and second 112, so that second 112 The other end intensity increase, to avoid second 112 other end breakable problem during installation or transport. Wherein, the central angle of the cambered surface 113 is 20 degree of -30 degree.

When the quantity of the first protrusion 1112 is multiple, near the separate ontology of second 112 first protrusion 1112 It is connected between 1111 outer edge and the edge of second 112 other end by cambered surface 113, as shown in Figure 1.

The integrated retainer 100 further includes the second protrusion 114 in one of the embodiments, and the second protrusion 114 is from Two 112 other ends extend out and are formed toward the direction far from second 112.By the setting of the second protrusion 114, into one Step increases the intensity of second 112 other end.Further, the shape of second protrusion 114 can be circular cone shape, thus When so that second protrusion 114 being also placed in transformer oil, the intensity of the second protrusion 114 is further increased, and avoids second 112 The other end during installation or transport breakable problem.It should be noted that in other embodiments, this is second convex It is cylindric etc. for playing 114 shape.

The length of the second protrusion 114 in their extension direction is 1 millimeter -3 millimeters in one of the embodiments,.Wherein, The extending direction of second protrusion 114 is consistent with the extending direction of the central axis of the cavity of insulating protective layer 110.

The integrated retainer 100 further includes shielding Intranet 130, shielding Intranet setting in one of the embodiments, In the cavities, and shielding Intranet is between copper rod 120 and the inner wall of cavity.Wherein, the material for shielding Intranet 130 can be to lead Electric rubber realizes the continuity of shielding with the cooperation of cable shield.

The integrated retainer 100 further includes nose-shaped cone 140 in one of the embodiments, and nose-shaped 140 setting of cone is the One 111 separate second 112 one end.The material of nose-shaped cone 140 is plastic cement, such as: fatty polyamide, EPDM Rubber etc..

Above-mentioned integrated retainer 100, including insulating protective layer 110, the insulating protective layer 110 include first 111 He Second 112, second 112 one end is fixedly connected with first 111, and second 112 other end is placed in transformer oil, The first protrusion that first 111 outer wall including ontology 1111 and from ontology 1111 extends out to the direction far from ontology 1111 1112, pass through arc between the outer edge of the separate ontology 1111 of first protrusion 1112 and the edge of second 112 other end Face 113 connects, and the central angle of the cambered surface 113 is far from the ontology, that is to say, where the cambered surface 113 to the first protrusion 1112 Direction indent, by the setting of cambered surface 113, so that the intensity of second 112 other end increases, to avoid second 112 other end breakable problem during installation or transport.

Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.
