Abstract
The invention relates to a lamp holder with a center positioning structure. The lamp holder comprises a lamp holder base, an insulator and a metal cap, wherein a wire hole is formed in the center of the insulator, a plurality of folded wire holes are formed in the periphery of the wire hole, and wire slots are formed between the wire hole and the folded wire holes in the periphery; the wire hole adopts a counter bore structure, and the diameter of one end of the wire hole is larger than that of the other end of the wire hole; a center pin is arranged on the metal cap and matched with the wire hole structure, and a power wire can be tightly pressed in the wire hole; the power wire conveniently enters the folded wire holes after folded in the wire hole by means of the wire slots of the insulator, and the counter bore structure of the wire hole and the matched center pin of the metal cap can have a center positioning function, so that the metal cap can be kept in the center position of the insulator while firmly pressing the power wire. According to the lamp holder, lead welding is not required, the structure is compact, the appearance is attractive, the connection is tight and reliable, assembly, disassembly or maintenance is facilitated, and environment protection is facilitated.
Description
Technical field
The present invention relates to lamp holder, particularly one is convenient to assembling, dismounting or maintenance, connects the closely reliable lamp holder with center location structure.
Background technology
At present; existing various holder structure is generally all made up of bulb socket, insulator and metal terminal; insulator is connected on bulb socket; bulb socket is connected with bulb or fluorescent tube, and metal terminal arranges on insulator and is connected with power lead, bulb or fluorescent tube, and power lead is normally welded on metal terminal; not quick detachable after welding; and it is attractive in appearance that lead welding exposes impact, and be also unfavorable for environmental protection, such lamp holder is also because torque not easily causes lamp holder to come off.
Summary of the invention
For the deficiency of above existing holder structure, the object of this invention is to provide one and be convenient to assembling, dismounting or maintenance, and it is closely reliable to be conducive to environmental protection, connection, with the lamp holder of center location structure.
The object of the invention is by realize by the following technical solutions:
With the lamp holder of center location structure, comprise bulb socket, insulator and metal cap, insulator is connected and fixed on bulb socket, bulb socket can be connected with bulb or fluorescent tube, metal cap arranges on insulator and is connected with power lead, and the center of described insulator is provided with wire guide, is provided with some broken line holes at the periphery of wire guide, metal cap is provided with centrepin, the centrepin of metal cap and insulator wire guide suitable and can power lead is closely pressed together in wire guide; Described insulator is located at the port of bulb socket, and the contact-making surface of bulb socket and insulator is provided with locking salient point, and insulator and bulb socket are connected to form overall structure.The wire guide of described insulator is counter bore structure, and one stomidium footpath is greater than other end aperture, and centrepin and the wire guide structure of metal cap are suitable, and the diameter of its corresponding one end is also greater than the diameter of the other end.
As the preferred technical solution of the present invention, the centrepin of described metal cap is also provided with groove.
As the preferred technical solution of the present invention, between the wire guide of described insulator and its periphery broken line hole, also have metallic channel.Described insulator is made of plastics, and plastic insulation is connected to form overall structure by injection mo(u)lding and bulb socket.
The invention has the beneficial effects as follows: from above structure, bulb socket is provided with locking salient point, and the overall structure that insulator and bulb socket injection moulding are formed is more tight, not easily loosens; The metallic channel of insulator is convenient to power lead and enters broken line hole after wire guide bending, counter bore structure and the metal cap centrepin suitable with it of wire guide can play centralized positioning effect, make metal cap can also remain in the center of insulator while firm pressing power lead.The present invention does not need lead welding, compact conformation, good looking appearance, connects closely reliable, is convenient to assembling, dismounting or maintenance, is of value to protection of the environment.
