Fix frequently with the screw lock mode shown in Fig. 1, fill screw thread glue after mounting screw again and strengthened, this connected mode is not
Only installation effectiveness is low, and easily locks bad pcb board.The invention of Publication No. CN201926687U is in the public affairs on the 10th of August in 2011
A kind of electric energy meter, including pcb board, zero line bonding jumper, manganese copper diverter and the terminal with signal terminal and current terminal are opened
Row, is provided with the connecting pin being connected with pcb board on the zero line bonding jumper, is provided with the manganese copper diverter and connects with pcb board
The sampling foot for connecing, the signal terminal and pcb board are connected by mode connects for screw, the connecting pin and sampling foot and pcb board
Connection all adopts grafting.Compared with prior art, this utility model simple production process, the phenomenon done over again is low, Material Cost and
Manual assembly cost and operation cost are low, and more accurately, reliability aspect is also greatly improved.In this utility model pcb board with
It is also to adopt screw connecting mode between signal terminal, it is low to there is also installation effectiveness, the drawbacks of easily lock bad pcb board.
Utility model content
Existing coil holder is low with the attachment structure installation effectiveness of pcb board, and easily locks bad pcb board, to overcome these defects,
This utility model provides the attachment structure of coil holder a kind of easy for installation and being hardly damaged pcb board and pcb board.
The technical solution of the utility model is：The attachment structure of a kind of coil holder and pcb board, including coil holder, coil holder top sets
There is pcb board, connected by fastening structure between coil holder and pcb board.Relative to need one by one lock-screw and gluing routine coil holder with
The method of attachment of pcb board is compared, and fastening structure can be that a step complete the connection of each junction point by pressing, easy to operate and carry
High efficiency of assembling.
Preferably, the fastening structure includes Elastic buckle, Elastic buckle is located at coil holder top.Elastic buckle can elasticity
Deformation, when connection coil holder is with pcb board, presses pcb board, and pcb board pushes Elastic buckle, sky can be conceded after Elastic buckle elastic deformation
Between cause pcb board can contact with connecting line top of the trellis, subsequent Elastic buckle elastic recovery, you can pcb board is snapped onto on coil holder.
Preferably, Elastic buckle includes buckle bar and guide head, buckle bar is fixedly arranged on coil holder, and guide head is fixedly arranged on card
Button bar top, guide head is provided with guiding surface and withholding of surface.Guiding surface is stress surface, is receiving again right when pcb board is extruded
The movement of pcb board is oriented to, when buckle bar guide head is squeezed can push card button bar flexure, conceding space crosses pcb board
Guide head, hereafter buckle bar resilience, the withholding of surface of guide head pushes down pcb board fixes it.
The structure preferably, Elastic buckle and coil holder are formed in one.Elastic buckle size is less, is integrally formed with coil holder
It is more readily processed and ensures installation accuracy and structural strength.
Preferably, coil holder is in a tubular form, coil holder is adapted to nesting with a stator core, pcb board in a ring, Elastic buckle snapping
In pcb board outer rim.This kind of coil holder can preferably be adapted to the attachment structure of pcb board with internal structure of motor, beneficial to the tight of motor
Gathering.
Preferably, Elastic buckle is multiple and is distributed in coil holder top port.Multiple Elastic buckles are uniform, can make
Pcb board multiple spot stress, and ensure stress equalization, the more conducively firm installation of pcb board.
The beneficial effects of the utility model are：
It is easy to operate, improve efficiency of assembling.This utility model, due to adopting fastening structure, can be that a step is complete by pressing
Into the connection of each junction point between coil holder and pcb board, for conventional attachment structure, step is less, easy to operate, can show
Write and improve efficiency of assembling.
It is hardly damaged pcb board.As long as fastening structure connection completes that stablizing for attachment force, power can be kept in this utility model
Degree is more easy to control, therefore is hardly damaged pcb board.
