Description
Technical field
The utility model relates to the tube lamp holders that a kind of lamp cap more particularly to a kind of creepage distance are greater than 3mm.
Background technique
Traditional tube lamp holder generally comprise the cylinder of aluminum or irony and in cylinder fixing plug pin insulating trip,
Wherein G5 lamp cap refers to that the spacing of two contact pins is 5mm.For security consideration, some professional standards have made specifically creepage distance
Regulation, as the creepage distance of the fixed G5 lamp cap of UL is not less than 3mm.So-called creepage distance refers between contact pin and cylinder in insulating trip
The linear distance on surface.
In order to increase the creepage distance between contact pin and cylinder, CN208186246U provides a kind of high voltage bearing pins type
Lamp cap, including lamp housing, and the insulation assembly being located on lamp housing, and the copper needle being arranged on insulation assembly；The insulation
Component includes the external insulation piece for being located in lamp housing upper surface, and is located in the interior insulation piece inside lamp housing；The lamp housing upper end
Face, which offers, keeps away electric hole, and the aperture for keeping away electric hole is greater than the diameter of copper needle, and copper needle end part is successively located in external insulation piece and interior insulation
On piece, the copper needle between external insulation piece and interior insulation piece keep away electric hole across described.The patent setting avoid holes increase copper needle with
Creepage distance between aluminum hull, but increased limited extent, the structure in addition fixing insulating trip are also relative complex.
For another example CN208186256U provides a kind of pin cap, including lamp housing, and the lamp housing is equipped with insulating trip, absolutely
Locating slots and two lower locating slots on two are respectively equipped on the upper surface and lower end surface of embolium, on two under locating slots and two
Locating slot is axially corresponding respectively and communicates equipped with location hole, and buckle is fixed with two copper needles respectively on two location holes.The patent
Increase creepage distance, but the force limited of the fixed insulating trip of aluminum hull by the way that locating slot is arranged in insulation, needs in insulating trip
Circumferential surface coating glue, then the end of aluminum hull is filled in, increase process costs.
Utility model content
The utility model provides that a kind of structure is simple, can increase the tube lamp holder of creepage distance.
A kind of tube lamp holder including metal cylinder and is fixed with the insulating trip of contact pin, the end tool of the metal cylinder
There is the flanging of a circle fold inward, there is a circle annular knurl, the insulating trip is by flanging and rolling on the periphery of the metal cylinder
Flower limitation is fixed on inside metal cylinder.
Preferably, the annular knurl overlaps with insulating trip.
Preferably, the outer peripheral surface of the insulating trip reclines the inner peripheral surface of metal cylinder completely.
Preferably, the creepage distance between the contact pin and metal cylinder is not less than 5mm.
Preferably, the metal cylinder is aluminum.
Preferably, heat release hole is provided on the insulating trip.
The utility model flanging can be by being stamped and formed out, and annular knurl can be placed in post-processing in metal cylinder in insulating trip
It is formed, flanging and annular knurl are mobile from both direction limitation insulating trip, and reliability increases considerably, and does not need glue bonding, simplifies
Technique, reduces production cost.
Detailed description of the invention
Fig. 1 is the sectional view of the utility model lamp cap.
Fig. 2 is the structural schematic diagram of the utility model lamp cap end.
Specific embodiment
As illustrated in fig. 1 and 2, a kind of G5 lamp cap, including metal cylinder 1 and insulating trip 2, the material of metal cylinder 1 are aluminium, when
So it is also possible to iron, aluminium ductility is more preferable, and density is smaller, is common selection.Insulating trip is formed by epoxy resin cure, is had
Certain hardness and processing intensity.
For the wall thickness of metal cylinder 1 probably in 0.3mm or so, it can be straight-tube shape, be also possible to segmentation structure, and
Each section of diameter is different.It is fixed with two copper contact pins 3 on insulating trip 2, there is annulus 31, annulus 31 and insulation on contact pin 3
The limit cooperation of piece 2, avoids contact pin from moving axially.Contact pin 3 passes through insulating trip 2, and the end passed through is stamped and formed out stop collar, makes
Contact pin 3 is obtained to be riveted on insulating trip 2.The inside of two root cutting needles 3 also has the perforation 32 for connecting electric wire.
The utility model lamp cap mainly improves the fixed form for being insulating trip 2, as shown in Figure 1, the end of metal cylinder 1
Fold inward forms this side 11, and all sides are provided with a circle annular knurl 12, and insulating trip 2 is fixed on gold by flanging 11 and the limitation of annular knurl 12
Belong to inside cylinder 1, i.e. close to flanging 11, the other side is knurled 12 and blocks insulating trip one side.
The annular knurl is conventional machining gimmick, it is to be stamped and formed out rough lines, shape in metal surface
The minute protrusions of insulating trip 2 are blocked at many.The intersection of insulating trip Yu metal cylinder 1 is arranged in annular knurl 12, theoretically annular knurl
12 can not be overlapped with insulating trip 2, but since insulating trip is generally formed from a resin, if annular knurl 12 and insulating trip 2 are overlapped, portion
The surface for dividing annular knurl 12 that can be embedded into insulating trip 2, increases the firmness of connection.
Insulating trip 2 will appear radial shaking in order to prevent, and the outer peripheral surface of insulating trip 2 touch the interior of metal cylinder 1 completely
Circumferential surface.The width of flanging 11 is bigger, can more block the insulating trip 2, but can reduce climbing between contact pin 3 and metal cylinder 1
Electrical distance α, in general, creepage distance α need to be set greater than 5mm.
