Welding connector female seat.
As shown in figure 3, connecting terminal 220, outlet are drawn in the back side of tapping block 200 provided with inlet wire draws connecting terminal 230 and lightning protection
Module draws connecting terminal 240.Inlet wire draws connecting terminal 220 and outlet to draw connecting terminal 230 respectively multiple, quantity is identical and one a pair
Should.Wherein inlet wire draws the connection outdoor equipment of connecting terminal 220, and the connection indoor equipment of connecting terminal 230 is drawn in outlet.Lightning-protection module, which draws, connects end
Son 240 is used for the foregoing lightning-protection module of grafting.Tapping block shown in Fig. 3 draws connecting terminal 220 and corresponding 6 tunnel including 6 road inlet wires
Connecting terminal 230 is drawn in outlet.
As shown in figure 4, inlet wire draws, connecting terminal 220, outlet draw connecting terminal 230 and lightning-protection module draws connecting terminal 240 and is located at
On first circuit board 250.As shown in figure 5, collection draws connecting terminal 210 and current sensor 270 on second circuit board 260.
First circuit board 250 and the parallel interval of second circuit board 260 and position is set with being relatively fixed.First circuit board 250 is outside
It is simultaneously the back side of tapping block 200, the outside one side of second circuit board 260 is the front of tapping block 200.
As shown in figure 4, drawing connecting terminal 220 per road inlet wire uses duplex terminal, i.e. Redundancy Design, maintain easily.Enter per road
Line draws connecting terminal 220 can be using cage spring connection terminal or screw fastening terminal etc..
When inlet wire draws connecting terminal 220 and outlet draws that corresponding terminal only uses voltage acquisition in connecting terminal 230, voltage is defined as
Signal terminal, is directly electrically connected on first circuit board 250 by the wire of laying.In fig. 4, it is assumed that left side it is uppermost enter
Line, which draws connecting terminal and draws the corresponding collection of connecting terminal 231 for voltage signal terminal 221 and outlet, introduces terminal, then corresponding right side is most
It is voltage signal terminal 231 that connecting terminal is drawn in outlet above, and voltage signal terminal 221 (inlet wire) (goes out with voltage signal terminal 231
Line) between wire on first circuit board 250 be directly connected to.
Draw connecting terminal 220 from inlet wire and outlet draws between corresponding voltage signal terminal on connecting terminal 230 that (for example voltage is believed
Number between terminal 221 (inlet wire) and voltage signal terminal 231 (outlet)) conductive path on any point, can extraction voltage letter
The voltage acquisition terminal in connecting terminal 210 is drawn in the collection that number gathering line is connected on second circuit board 260.As it was previously stated, collection
Drawing connecting terminal 210 at least includes voltage acquisition terminal and current acquisition terminal.Therefore, the voltage signal inputted from inlet wire can be led to
Connecting terminal 210 is drawn in collection, and into acquisition module after acquisition module grafting.
When inlet wire draws connecting terminal 220 and outlet draws corresponding terminal in connecting terminal 230 and needs to be used for current acquisition, it is defined as
Current signal terminal, connects by the cable 251 outside first circuit board 250 and (refers to Fig. 5).It is assumed that left side
A middle inlet wire draws connecting terminal for current signal terminal 223, then it is electric current that connecting terminal is drawn in the outlet in the middle of corresponding right side
Signal terminal 233 (Fig. 5 does not show), by cable between current signal terminal 223 (inlet wire) and current signal terminal 233 (outlet)
251 connections.The punching in the same direction of cable 251 passes through current sensor 270.When electric current is by cable 251, current sensor
270 can inductive pick-up current signal.Cable 251 uses high temperature flame-proof line.
Current sensor 270 is arranged on second circuit board 260 in itself, and its output end may be connected to the collection and draw and connect end
Current acquisition terminal in son 210.Therefore, the current signal inputted from inlet wire can lead to collection and draw connecting terminal 210, and in collection
Enter acquisition module after module grafting.
The voltage and current signal gathered the need for each equipment is general not over 6 tunnels, therefore draws with 6 road inlet wires and connect
The tapping block 200 that connecting terminal is drawn in the tunnel outlet of terminal 220 and 6 can provide the signal for accessing and gathering an equipment.Set when more
Back-up is not connected after respective tapping block 200, it is possible to realize carry out concentrated collection and the processing of many device signals.
As shown in figure 4, connecting terminal 240 is drawn in each lightning protection includes 5 inserting grooves 241.Outside lightning-protection module (not shown)
It can be plugged on by inserting groove 241 on tapping block 200, be that voltage and current signal carries out lightning protection.
Further, lightning protection draws void area of the connecting terminal 240 in inserting groove 241 provided with detection switch 243 in place.In place
Detection switch 243 is used to detect whether lightning-protection module is in place.Detection switch 243 in place, which also connects, to be led on second circuit board 260
The signal terminal in place in connecting terminal 210 is drawn in collection.When the normal grafting of lightning-protection module, detection switch 243 in place is depressed, produced
Raw signal in place.When lightning-protection module is not inserted normally, detection switch 243 in place is unable under positive normal pressure, is produced dislocation or is deteriorated
Signal.3 detection switch 243 in place are provided with first circuit board 250, it is drawn by independent line respectively is connected to the second circuit
Plate 260, then draws and is connected to collection and draws in connecting terminal 210.
Therefore collection, which is drawn, can include voltage acquisition terminal, current acquisition terminal, lightning protection state-signal collection end in connecting terminal 210
Son is signal terminal in place etc..These terminals can input corresponding signal in acquisition module, and line number is entered by acquisition module
According to processing, then collect.
