Abstract
The utility model discloses a connection device for connecting an electric energy meter terminal strip and a main board, which comprises a bakelite body and a plurality of auxiliary terminals of the terminal strip and a conversion card. The conversion card is connected with the main board; each auxiliary terminal is formed by a small copper strip and a spring sheet; the small copper strip is embedded inside the bakelite body and used for conducting weal current; one end of the spring sheet is fixed inside the bakelite body; and the other end of the spring sheet is electrically connected with the small copper strip and the main board to be used for transmitting the weak current of the small copper strip to the conversion card. In the connection device for connecting the electric energy terminal strip and the main board, each auxiliary terminal of the terminal strip is fixed with one spring sheet and connected with the main board through one conversion card, and the conversion card is tightly pressed on the spring sheet to ensure reliable connection of the terminal strip and the conversion card. The spring sheets are welded on the terminal strip to form a whole without adding working positions for processing. The connection device saves material cost, simplifies operation, improves working efficiency and ensures production quality of products.
Description
Technical field
The utility model relates to a kind of coupling arrangement that energy meter terminal row is connected with mainboard that is used for.
Background technology
The terminal row of general electronic electric energy meter is to be connected with mainboard by cable, and mainboard is connected with the cable of terminal row by a band brace, and the cable other end is welded on the mainboard.The mounting means of this mode is: earlier cable is welded in the printed board, cable is screwed on terminal row again.Above-mentioned two steps just are converted into two stations aborning.The first step can only adopt manual welding because the singularity of this cable can not be crossed wave-soldering, so following weak point is arranged: (1) needs to increase a station, has just increased man-hour; (2), there is the wrong possibility of line weldering for the model that both positive and negative polarity is arranged; (3) increased Material Cost---scolding tin and cable.The weak point in second step is because the auxiliary terminal of current client request has following several: pulse terminal, RS48 communication terminal, pulse per second (PPS) lead-out terminal, the card table, what have also needs external relay output end, alarm relay lead-out terminal etc., when auxiliary terminal quantity increases, just need to increase corresponding man-hour.So just make the operation link of electronic electric energy meter flow of installation various, the probability of errors height, production efficiency is low.
The utility model content
The purpose of this utility model is to provide that a kind of operation link is few, production efficiency is high, product quality is high, need not the coupling arrangement that energy meter terminal row is connected with mainboard that is used for that cable connects.
This energy meter terminal that is used for that the utility model provides is arranged the coupling arrangement that is connected with mainboard, the bakelite body and the some auxiliary terminals that comprise terminal row, also comprise a card extender that is connected with mainboard, described auxiliary terminal is formed by being embedded in the little copper bar and the shell fragment that are used for logical light current in the described bakelite body, one end of described shell fragment is fixed in the bakelite body, the other end is electrically connected with little copper bar and card extender, is used for giving card extender with the light current of little copper bar.
Described shell fragment is a waveform.
Described shell fragment is the waveform with two peaks.
This coupling arrangement that energy meter terminal row is connected with mainboard that is used for of the present utility model, each auxiliary terminal of terminal row is fixed a shell fragment, is connected with mainboard by a card extender again.Card extender is pressed on the shell fragment, guarantees that terminal row is connected with the reliable of card extender.This shell fragment is welded on and becomes as a whole on the terminal row, need not to increase station and handles.The utility model has been saved Material Cost, has simplified operation, has improved production efficiency, has guaranteed the quality of production of product.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the B portion enlarged drawing of Fig. 2;
Fig. 4 is the prior art constructions synoptic diagram.
Embodiment
From Fig. 1 and Fig. 3 as can be seen, this coupling arrangement that energy meter terminal row is connected with mainboard that is used for of the present utility model, bakelite body 1, some auxiliary terminals 2 and a card extender 4 of comprising terminal row, auxiliary terminal 2 is made up of the little copper bar 5 and the shell fragment 3 that are embedded in the described bakelite body 1, little copper bar 5 is used for logical light current, shell fragment 3 is for having the waveform at two peaks, one end of shell fragment 3 is fixed in the bakelite body 1, the other end is electrically connected with little copper bar and card extender, is used for giving card extender with the light current of little copper bar 5.Card extender 4 is connected with mainboard and is screwed on bakelite body 1, and is adjacent with bakelite body 1, utilizes the elasticity of waveform shell fragment 3 to guarantee that terminal row is connected with the reliable of card extender 4.
The deformation stroke of the utility model shell fragment 3 can not be too little, otherwise the connection reliability of terminal row and card extender 4 can not get guaranteeing; But can not be excessive, otherwise the intensity of card extender 4 can't mate with it, can cause the card extender fracture.Increase the peak face of the contact area method of shell fragment and card extender for increase waveform shell fragment, the one, the number at increase peak, another one are the width that increases the peak.Consider the dielectric test of electric energy meter, the width of bullet pad need decide according to actual conditions.
Card extender decided with being connected according to actual conditions of mainboard.If all terminals all need, then the track of auxiliary terminal by card extender can be caused same double socket, be connected with mainboard by contact pin.When signal corresponding on certain terminal during as an optional function, take a terminal row because of this separately with this terminal this moment, and the terminal corresponding with essential function keeps the interval of 6mm.
Claims (3)
1. one kind is used for the coupling arrangement that energy meter terminal row is connected with mainboard, the bakelite body (1) and the some auxiliary terminals (2) that comprise terminal row, it is characterized in that also comprising a card extender that is connected with mainboard (4), described auxiliary terminal (2) is formed by being embedded in the little copper bar (5) and the shell fragment (3) that are used for logical light current in the described bakelite body (1), one end of described shell fragment (3) is fixed in the bakelite body (1), the other end is electrically connected with little copper bar (5) and card extender (4), is used for giving card extender (4) with the light current of little copper bar (5).
