Further, it is provided with the limiting slot 64 with perforation notch on the lower surface of Neto 6, is provided in the limiting slot 64
First limiting section 65 is provided with the opening being connected with the notch of limiting slot 64 on first limiting section 65, passes through first through hole
61 the first lamp base 71 turns down and in the opening of the first limiting section 65, corresponding, and the second limiting section is formed on seesaw 8
81, the upper end of spring 9 is socketed on the first limiting section 65, is located in limiting slot 64, and is pressed on the first lamp base 71, spring 9
Lower end be socketed on the second limiting section 81, so can be realized the reliable location of spring 9, realize the first lamp base 71 and seesaw 8
Always it is connected.
Further, live conductor lid 10 is set at corresponding second through-hole 62 in the lower surface of Neto 6, the second lamp base 72 passes through second
It is pressed on after through-hole 62 on crimping lid 10, connecing for the second lamp base 72 and third connecting terminal 4 is effectively increased by crimping lid 10
Contacting surface product, to improve the reliability that the second lamp base 72 is abutted with third connecting terminal 4 in 5 rotation process of button.
As shown in figure 5, the both ends of Neto 6 are provided with guidance part 66, which is that upper end width is wide less than lower end
The incline structure of degree, i.e., in figure at A size be less than B at size can be avoided the assembling of button 5 Yu Neto 6 with this configuration
Damage Neto 6 by pressure in the process；It is preferred that the side wall middle part between 6 both ends of Neto is the structure that is recessed inwardly, so filled by button assembly
When entering bottom case 1, button assembly can be inside contracted, to avoid damaging by pressure the opening of bottom case 1；Preferably, positioned at 6 both ends of Neto
The two sidewalls of guidance part 66 extend outward the two sidewalls for protruding from Neto 6, and both ends protrusion is formed in Neto 6, and middle part is recessed
Sunken structure forms hierarchic structure 67 at the both ends of Neto 6, is provided in the side wall surface of the inner cavity of button 5 and is used for and ladder
The convex closure structure 51 that structure 67 is clasped can be realized Neto by the convex closure structure 51 and being clasped for hierarchic structure 67
6 are bonded with button 5, avoid separating in automatic assembling process.
Further, the upper surface of Neto 6 is provided with baffle 68 relative to the two sides of 7 installation site of neon lamp, after neon lamp 7 turns down
It is placed between two baffles 68, realizes to the height limit of 7 arranged on left and right sides of neon lamp, avoid pressing in Neto 6 and 5 assembling process of button
Bad neon lamp 7.
Compared with prior art, the configuration of the present invention is simple can be abutted between components by interaction and realize and be electrically connected
It connects, so as to avoid additional wiring, so that easy to assembly；First through hole and the second through-hole are arranged at the one of Neto simultaneously
End carries out automatic assembling so as to facilitate machine to realize neon lamp, improves production efficiency, reduce production cost；Furthermore it is interior
Be recessed inwardly structure in the middle part of support use, consequently facilitating button assembly inside contracts when being packed into bottom case, to avoid weighing wounded the opening of bottom case；
It can be avoided the first lamp base by partition and short circuit occur for the second lamp base；By the baffle of Neto two sides, neon lamp peace can be realized
Two sides limit when dress, and button and Neto is avoided to damage neon lamp by pressure when installing.
Disclosed above is only the embodiment of the present invention, and still, the present invention is not limited to this, the technology of any this field
What personnel can think variation should all fall into protection scope of the present invention.
