One negative wire connection terminal 104b offsets with the second negative wire connection terminal 204b.
It should be noted that the first crossover sub 101, the first plug-in unit 102 have inner cavity, the two is connection；First
The left and right ends of positive wire connection terminal 104a and the left and right ends of the first negative wire connection terminal 104b are respectively positioned on outside the first fixed block 103
Portion；The material conductive material of the first positive negative wire connection terminal 104b of wire connection terminal 104a and first, such as aluminium alloy.In addition, second
Crossover sub 201, the second plug-in unit 202 have inner cavity, and the two is connection；The right end and second of second positive wire connection terminal 204a
The right end of negative wire connection terminal 204b is respectively positioned on outside the second fixed block 203；The second positive negative terminals of wire connection terminal 204a and second
The material conductive material of sub- 204b, such as aluminium alloy.
Below by taking the installation of instrument as an example, table is based on regard to the operation principle of the instrument connector of the utility model embodiment offer
It states：
Before being installed to instrument, by the positive and negative electrode of instrument respectively with the first positive wire connection terminal 104a, the first negative wiring
Terminal 104b is electrically connected；And by the positive and negative electrode of explosion-proof tank electric wire respectively with the second positive wire connection terminal 204a, the second negative terminals
Sub- 204b electrical connections
When installing instrument, the first positive wire connection terminal 104a is first passed through to the second through hole on the second fixed block 203 respectively
It offsets with the second positive wire connection terminal 204a and leads to the first negative wire connection terminal 104b through second on the second fixed block 203
Hole offsets with the second negative wire connection terminal 204b；The first plug-in unit 102 and the second plug-in unit 202 are connected afterwards, and then realized to instrument
The installation of table.
As it can be seen that the instrument fast connector that the utility model embodiment provides, by setting first in first assembly 1 just
The negative wire connection terminal 104b of wire connection terminal 104a and first and the second positive wire connection terminal 204a and the is set in the second component 2
Two negative wire connection terminal 204b, and the first positive wire connection terminal 104a can offset with the second positive wire connection terminal 204a, the first negative terminals
Sub- 104b offsets with the second negative wire connection terminal 204b so that the positive and negative electrode of instrument and the positive and negative electrode of explosion-proof tank electric wire are electrically connected
It connects；By the way that the first plug-in unit 102 and the second plug-in unit 202 are detachably connected, convenient for the installation and dismounting of instrument, such as instrument is dismantled
Time be down to 5 minutes or so by 30 minutes before.
Further, the first positive negative wire connection terminal 104b of wire connection terminal 104a and first are fixed with the first fixed block 103
The mode of connection and by the negative wire connection terminal 204b of the second positive wire connection terminal 204a and second and 203 company of fixation of the second fixed block
There are many modes connect, for example, as shown in Figure 1, the utility model embodiment is axially disposed on the first fixed block 103 two
A first through hole, the first positive negative wire connection terminal 104b difference fixing sleeves of wire connection terminal 104a and first are arranged in first through hole；The
It is axially disposed there are two the second through hole on two fixed blocks 20, the second positive negative wire connection terminal 204b's of wire connection terminal 204a and second
Left end difference fixing sleeve is arranged in second through hole.This kind of connection mode is easily installed and dismantles.
When the first positive positive wire connection terminal 204a of wire connection terminal 104a and second are offseted, the first negative wire connection terminal 104b and
When two negative wire connection terminal 204b offset, easily occur the first positive negative wire connection terminal 204b of wire connection terminal 104a and second offset, second
The situation that the positive negative wire connection terminal 104b of wire connection terminal 204a and first offset so that the positive and negative electrode of instrument and explosion-proof tank electric wire
Positive and negative electrode is reversed, and causes the scaling loss of instrument.
In order to avoid the generation of the above situation, based on above-mentioned connection mode, the first positive wiring of the utility model embodiment
The negative wire connection terminal 104b sizes of terminal 104a and first are different, and accordingly, two the second clear size of opening are different.That is, by
Size difference, the second clear size of opening in the first positive negative wire connection terminal 104b of wire connection terminal 104a and first is different, and first just connects
Line terminals 104a can only offset through corresponding second through hole with the second positive wire connection terminal 204a, and the first negative wire connection terminal 204a
It can only offset through corresponding second through hole with the second negative wire connection terminal 204a, and then the positive and negative electrode of instrument can be avoided reversed, prevent
Only instrument scaling loss.
For example, the outer diameter of the first positive wire connection terminal 104a can be more than to the outer diameter with the first negative wire connection terminal 104b, accordingly
Ground is arranged with the aperture of the second through hole of the second positive wire connection terminal 204a also greater than being arranged with the of the second negative wire connection terminal 204b
The aperture of two through holes.Like this, the first positive wire connection terminal 104a can only pass through corresponding second through hole and the second positive terminals
Sub- 204a offsets, the first negative wire connection terminal 104b can only be offseted by corresponding second through hole and the second negative wire connection terminal 204b,
Ensure that the positive and negative electrode of electrical connection instrument is electrically connected with the positive and negative electrode of explosion-proof tank electric wire, the positive and negative of instrument will be electrically connected by avoiding
The pole situation reversed with the positive and negative electrode of explosion-proof tank electric wire.
When according to above-mentioned connection mode, to set the first positive wire connection terminal 104a, the first negative wire connection terminal 104b and first
When the structure and position relationship of fixed block 103, since instrument connector can shake in use, make the first positive wiring
