Under, also with being easily installed the characteristics of.
Above-mentioned purpose of the present utility model technical scheme is that：
Be easy to the charactron for assembling, including pcb board, reflect shell and pcb board is fixed on for connecting the contact pin of panel,
The panel is provided with wears the control hole penetrated for the contact pin, and the pcb board is provided with some preformed holes, and the contact pin runs through
The preformed hole, the preformed hole are divided into functional preformed hole and nonfunctional preformed hole, and the pcb board is fixed with the reflection shell
Connection, the nonfunctional preformed hole are installed with nonfunctional contact pin, when the contact pin is arranged on the panel, described idle
Energy contact pin is abutted with the panel.
By adopting above-mentioned technical proposal, nonfunctional contact pin is set, when contact pin is arranged on described on nonfunctional preformed hole
When on panel, nonfunctional contact pin is abutted with the panel, so as to play when charactron is arranged on panel, by nothing
Function contact pin is connect with panel, so as to play a part of firm charactron, and without extra setting pad or footmuff, such as
This setting, can greatly save the set-up time, improve installation effectiveness, and it is convenient to provide for installation.
Used as improvement of the present utility model, the nonfunctional preformed hole is pressed with nonfunctional contact pin.
Pressed and functional preformed hole and contact pin with nonfunctional contact pin by adopting above-mentioned technical proposal, nonfunctional preformed hole
Mounting means it is identical, it is possible to press nonfunctional preformed hole and nothing together when functional preformed hole and contact pin are installed
Function contact pin, improve production efficiency.
Used as improvement of the present utility model, two sides up and down of the pcb board are disposed as circuit, described functional pre-
Hole copper coating is electroplate with the hole wall boxed out.
Circuit is provided with by adopting two sides up and down of above-mentioned technical proposal, pcb board, subtracts the volume of circuit board
Little, in order to preferably facilitate the connection between circuit, electroplating in functional preformed hole is free copper coating, can be plated by hole copper
The circuit of the upper and lower both sides of the upper and lower pcb board of layer conducting.
Used as improvement of the present utility model, the nonfunctional preformed hole is arranged on corner or the lateral location of circuit board.
By adopting above-mentioned technical proposal, nonfunctional preformed hole is arranged on circuit board does not have the position of circuit, typically sets
Put in the corner of pcb board or edge placement, to prevent the electric wire arrangement to pcb board from producing interference.
In sum, this utility model has the advantages that：Nonfunctional contact pin is set on nonfunctional preformed hole, when
When contact pin is arranged on the panel, nonfunctional contact pin is abutted with the panel, is arranged on control when charactron so as to play
When in making sheet, connect with panel by nonfunctional contact pin, so as to play a part of firm charactron, and without extra setting
Pad or footmuff, are arranged such, and can greatly save the set-up time, improve installation effectiveness, and it is convenient to provide for installation.

Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing.
With reference to shown in Fig. 2 and Fig. 3, it is easy to the charactron for assembling to include pcb board 5, reflection shell 1 and connection panel 4
Contact pin 3, wherein, pcb board 5 is provided with some preformed holes, respectively functional preformed hole and nonfunctional preformed hole, wherein, it is active
Can preformed hole be set to 12, be distributed in the both sides of pcb board 5, side by side and be placed equidistant as 6 per side, wherein, nonfunctional is reserved
Hole is provided with the both sides of functional preformed hole, and contact pin 3 is all equipped with each preformed hole, positioned at the contact pin 3 of functional preformed hole
