For achieving the above object, this utility model is using such as purgation technical scheme：

A kind of forced high insulation lamp holder, includes metal casing, insulating lid and interior insulation sheath；The metal casing has The top for having one first containing cavity, metal casing has a through hole, and the through hole connects the first containing cavity；The insulating lid and metallic sheath Shell produced by insert molding is fixedly connected and positioned at the top of metal casing, and the inner of insulating lid is stretched in the first containing cavity through through hole, And insulating lid has the installing hole for being used to installing conductive cap；The interior insulation sheath is placed in the first accommodating intracavity, interior insulation sheath tool There are one second containing cavity, the second containing cavity connection installing hole, the top of interior insulation sheath and the inner of insulating lid to snap connection solid It is fixed.

Used as a kind of preferred version, the inner of the insulating lid is convexly equipped with buckle, is provided with the top of the interior insulation sheath Hole clipping, the hole clipping connect the second containing cavity and snap connection fixation with buckle.

Used as a kind of preferred version, the buckle is annular in shape, and which radially expanded extends in the inner periphery of insulating lid.

Used as a kind of preferred version, the outer wall of the interior insulation sheath is convexly equipped with multiple fins, the plurality of fin interval row Cloth, each fin are axially extending, and each fin is butted on the internal face of the first containing cavity.

Used as a kind of preferred version, the metal casing is aluminum nickel plating, copper nickel plating, rustless steel, copper or aluminium material.

This utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology Scheme understands：

By insulating lid is fixedly connected with metal casing produced by insert molding, and coordinate interior insulation sheath press-in metal casing The first containing cavity in snap connection fixation with the inner of insulating lid, need not more consolidate, will not go out using screw assembling, structure Now loosen, using more safe and reliable, assemble simpler convenience, and effectively prevent metal casing deformation, so as to improve product Product qualification rate.

More clearly to illustrate architectural feature of the present utility model and effect, come right with specific embodiment below in conjunction with the accompanying drawings This utility model is described in detail.

Specific embodiment

Refer to shown in Fig. 1 to Fig. 4, that show the concrete structure of the preferred embodiment of this utility model, include Metal casing 10, insulating lid 20 and interior insulation sheath 30.

The top that the metal casing 10 has one first containing cavity 11, metal casing 10 has a through hole 12, the through hole 12 Connect the first containing cavity 11；In the present embodiment, the metal casing 10 is aluminum nickel plating, copper nickel plating, rustless steel, copper or aluminium Matter, the material of metal casing 10 are not limited.

The insulating lid 20 is fixedly connected with 10 produced by insert molding of metal casing and positioned at the top of metal casing 10, insulating lid 20 The inner stretch in the first containing cavity 11 through through hole 12, and insulating lid 20 has for installing conductive cap（Do not show in figure）Peace Dress hole 21.

The interior insulation sheath 30 is placed in the first containing cavity 11, interior insulation sheath 30 have one second containing cavity 31, second Containing cavity 31 connects installing hole 21, and the top of interior insulation sheath 30 snaps connection fixation with the inner of insulating lid 20.Specifically, The inner of the insulating lid 20 is convexly equipped with buckle 22, and the top of the interior insulation sheath 30 is provided with hole clipping 32, and the hole clipping 32 is connected Second containing cavity 31 simultaneously snaps connection fixation with buckle 22, also, the buckle 22 is annular in shape, and which is in the inner week of insulating lid 20 Edge is radially expanded to be extended, so that interior insulation sheath 30 is connected with insulating lid 20 more consolidating.And, the interior insulation sheath 30 outer wall is convexly equipped with multiple fins 33, and the plurality of fin 33 is intervally arranged, and each fin 33 is axially extending, and each fin 33 are butted on the internal face of the first containing cavity 11.
