Embodiment
Present invention is described further below in conjunction with drawings and Examples.
As Figure 1-4, the component includes fixed seat 1 and four inserting terminals 2, and the fixed seat both ends are provided with positioning hole 11, inside is provided with the holding tank that quantity is quite used to fix inserting terminal 2 with inserting terminal 2, and the inserting terminal 2 is placed on Coordinated in holding tank and by positioning hole 11 and screw and fixed seat 1 is arranged on ammeter box to fix and protect connecting element Structure.The inserting terminal 2 is fixed between fixed seat and ammeter box, including integrally formed connection-peg 22 and connecting portion.Such as Shown in Fig. 3, the connection-peg 22 is hollow cylinder structure, the cross recess 221 of axially disposed insertion connection-peg 22 since top, The cross recess 221 divides connection-peg 22 for four parts, and this four part can form a tool with stress inwardly or outwardly deformation Flexible connection-peg 22, the front end of connection-peg 22 is provided with certain guide ramp, to facilitate grafting.It is provided with cross recess 221 The hole 222 of certain depth, preferred depth 15mm, the inside of hole 222 are provided with a support elastic sheet 23.As shown in figure 4, this implementation In example, the support elastic sheet 23 is hollow cylinder structure, and an opening for being easy to deformation is provided with vertically on its cylindrical periphery face 231, and its cross section is in c character form structures.The c character form structures are used in the 23 compression deformation of support elastic sheet, can provide Certain deformation range, its Flexible change amount is set typically to be not less than 0.5mm.The external diameter of support elastic sheet 23 is slightly larger than connection-peg 22 The aperture of endoporus 222, so that the support elastic sheet 23 can in the endoporus 222 of connection-peg 22 by surrounding because of cross recess 221 and The four part connection-pegs 22 separated strut, and the external diameter of connection-peg 22 is expanded to more than 7.6mm from 7.6mm, more than the ammeter interface Aperture 7.5mm, connection-peg 22 can be achieved and be connected with the interference fit of ammeter interface, increase connecing for connection-peg 22 and ammeter interface Contacting surface is accumulated, and improves the reliability of connection, and the connection-peg 22 should meet in national standard to the temperature increase requirement of ammeter plug connector.It is described Connecting portion end is provided with a jack 24 for being used to connect external cable, is additionally provided with connecting portion side and consolidates with what jack 24 connected Determine hole 25, can be by the way that screw be installed in fixing hole 25, before screw when needing external cabling being linked into jack 24 End can compress wire, realize the fixation of external cabling.The connecting portion is additionally provided with a screw 26, and the screw 26 is used by screw It is fixed in by inserting terminal 2 on ammeter box.
In the present embodiment, the pcb board 3 for placing communication module is additionally provided with fixed seat 1, the both ends of pcb board 3 are provided with For connecting the incoming end 33,34 of external communication bus, its incoming end 33,34 is realized by communication module and ammeter communication interface Electrical connection.Preferably, one group of elastic probe 31,32 is respectively equipped with the both ends of pcb board 3, the elastic probe 32 of left end connects Left end incoming end 34 realizes ammeter and outside outer signal communication of operating a switch, and the elastic probe 31 of right-hand member connects right-hand member incoming end 33 and realized Ammeter and outside RS485 signal communications.The elastic probe is respectively used to outer operate a switch control interface and the RS485 communications of grafting ammeter Interface, including the fixed part 311,321 of integrally connected and elastic movable part 312,322 can be realized on fixed part, should Fixed part 311,321 is fixed on pcb board 3, and is connected with RS485 communication modules.So, when right-hand member elastic probe 31 is plugged into When at RS485 communication interfaces, movable part 312 contacts with the RS485 communication interfaces of ammeter, ammeter RS485 communication interfaces is led to Cross communication module to be connected with outside RS485 buses, realize that ammeter is communicated with external equipment.When the grafting of left end elastic probe 32 To ammeter it is outer operate a switch control port when, movable part 322 contacts with the outer control interface of operating a switch of ammeter, makes ammeter can be according to external Outer operate a switch control signal to realize that ammeter bus slave is switched on or switched off.
The present invention also protects a kind of ammeter box for including above-mentioned connecting element, and the ammeter box when in use, if desired should Ammeter is plugged on the ammeter connecting element, it is only necessary to the electrical wire interface of ammeter is aligned to the inserting terminal of the connecting element, it is past Lower firmly to be depressed, now, the connection-peg 22 on connecting element inserting terminal 2 is because its external diameter will than the aperture of ammeter interface Greatly, the deformation inside under by the extruding of ammeter interface of connection-peg 22, at this moment the support elastic sheet 23 in endoporus 222 be pressurized and shrink, because The effect of elastic force supports the state that connection-peg 22 keeps interference fit with ammeter interface, increase connection-peg 22 and ammeter interface Contact area, improve the reliability of contact.The elastic probe 31,32 of relevant position can also connect with the communication interface in ammeter simultaneously It is logical, finally by outer lead by being linked into the jack 24 of inserting terminal 2, passed through by screw in fixing hole, before screw End can compress wire, realize the fixation of external cabling.If desired the ammeter is removed from ammeter box, if then by using Instrument up firmly removes ammeter, reduces attendant and dismounts difficulty, substantially increases disassembly efficiency.
It is the wherein specific implementation of the present invention above, its description is more specific and detailed, but can not therefore manage Solve as the limitation to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, do not departing from On the premise of present inventive concept, various modifications and improvements can be made, these obvious alternative forms belong to this hair Bright protection domain.
