Abstract
The utility model relates to a soldering tin-free lamp base, comprising a lamp holder, an insulating piece and a conductive head. The two ends of the insulating piece are respectively connected with the lamp holder and the conductive head; the center of the insulating piece is provided with a lead wire central through hole; and the insulating piece is provided with a wire guide on the end plane of one side facing to the conductive head. The technical proposal of the utility model is that a foot lock extends out of one part of the conductive head corresponding to the central lead wire central through hole of the insulating piece. Because the matching position of the conductive head and the insulating piece extends into the lamp holder, the utility model is not limited by the standard size of the lamp base. The matching length of the conductive head and the insulating piece is prolonged and consequently the matching reliability of the conductive head and the insulating piece is improved greatly.
Description
Affiliated technical field
The utility model relates to a kind of solderless tin lamp head.
Background technology
The lamp holder of prior art great majority adopt the scolding tin technology, and glass is fired top at lamp socket as insulating part, on the top of glass with scolding tin with lead fixed and with scolding tin as conductive head.This technology is made the energy consumption height, weight is big, and Glass breadks easily is its main shortcoming.A kind of follow-on solderless tin lamp head is arranged now, its insulating part adopts plastics, though overcome the shortcoming of traditional lamp holder, but this modified model lamp holder utilizes the edge of conductive head to realize both connection with the close-fitting of insulating part corresponding position, owing to be subjected to the standard-sized thickness that limits the cooperation of this place of lamp holder very short, assembling is inconvenient on the one hand, also is easy on the other hand come off.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, and the reliable solderless tin lamp head of assembling between a kind of conductive head and the insulating part is provided.
The utility model comprises lamp socket, insulating part and conductive head, the two ends of insulating part connect with lamp socket and conductive head respectively, the central authorities of insulating part are provided with the lead center through hole, insulating part is provided with metallic channel towards a side end face of conductive head, and its technical solution is that the position of the corresponding insulating part centre drift of described conductive head center through hole is extended with the button pin.
Its conductive head of lamp holder of employing said structure and the cooperation position between the insulating part are owing to be the inside of stretching at lamp socket, therefore can not be subjected to the standard-sized restriction of lamp holder, make the length of fit between conductive head and the insulating part extend, thereby the cooperation reliability between conductive head and the insulating part is improved greatly.
Description of drawings
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1: the structural representation of present embodiment;
Fig. 2: the upward view of present embodiment insulating part.
Embodiment
As shown in the figure, present embodiment comprises lamp socket 1, insulating part 2 and conductive head 3, the two ends of insulating part 2 connect with lamp socket 1 and conductive head 3 respectively, the central authorities of insulating part 2 are provided with lead center through hole 21, insulating part 2 is provided with metallic channel 22 towards the end face of a side of conductive head 3, metallic channel 22 is extended to the edge by lead center through hole 21, is provided with lead fixed hole 24 on metallic channel 22 or its elongated end, the lead fixed hole is set can makes lead easier being fixed when assembling; The position of conductive head 3 corresponding insulating part 2 lead center through hole 21 is extended with buckles pin 31, and button pin 31 is provided with chamfering 32, and chamfering 32 is several and presses axial distribution in the present embodiment, and conductive head is buckled on insulating part better by the button pin; Insulating part 2 extend into into towards a side of lamp socket 1 and forms inserting end 23 in the lamp socket 1, the inside recessed formation inwall 11 in lamp socket 1 corresponding position, and inboard wall of lamp holder 11 is extruded into insulating part inserting end 23 by punching press and realizes being fixedly connected between lamp sockets 1 and the insulating part 2.
During assembling, lead is drawn from inside to outside from the lead center through hole of insulating part, extend, and in insulating part, draw back by the lead fixed hole along metallic channel, at last with the button climbers of conductive head in the conduction center through hole of insulating part, realized the assembling of lead, insulating part and conductive head.
The chamfering structure of button pin is a kind of fairly simple also than a kind of mode that is easier to implement in the utility model, and the button leg structure can also adopt other known versions according to actual needs.
