The position of side is separately installed with one group of Signal plug, and every group of Signal plug is made of two Signal plugs, two Signal plugs it
Between connected by connecting rod, and the electric initiating explosive device private jack is electrically connected respectively by cable with Signal plug.
Further technical solution is that the chassis interior is also filled with epoxy resin.
Further technical solution is that the electric initiating explosive device private jack is fixed by the second screw and washer with pedestal
Connection.
Further technical solution is that the Signal plug is fixedly connected by nut with cover board.
Further technical solution is that passing through the first screw and washer respectively in the position at four angles of cover board will cover
Plate is fixedly connected with pedestal.
Further technical solution is that the pedestal is made of aluminium alloy, and the connecting rod is made of brass.
Further technical solution is that the cover board is phenolic board, and the Signal plug is PS-MT Signal plug.
Compared with prior art, the beneficial effects of the present invention are:
There are four the advantages of terminal measurement for this interface arrangement tool, and have and be reliably connected with electric initiating explosive device plug, contact surface
The big advantage of product., by the electric initiating explosive device private jack on interface arrangement, realize and connect with the close of priming system plug inside contact pin
Touching, since socket and plug contact pin is contact of the face with face, so highly reliable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the interface arrangement for electric initiating explosive device resistance measurement of an embodiment of the present invention.
Fig. 2 is the A-A of Fig. 1 to schematic cross-sectional view.
Fig. 3 is the B-B direction schematic cross-sectional view of Fig. 1.
As shown, wherein corresponding appended drawing reference title are as follows:
1 pedestal, 2 cover boards, 3 Signal plugs, 4 nuts, 5 first screws, 6 electric initiating explosive device private jacks, 7 cables, 8 connections
Bar, 9 second screws.
Specific embodiment
The present invention is further elaborated with reference to the accompanying drawing.
A kind of interface arrangement for electric initiating explosive device resistance measurement as shown in Figs. 1-3, it includes pedestal 1 and is mounted on bottom
The cover board 2 of 1 top of seat, which is characterized in that 1 bottom of pedestal offers mounting hole, and it is dedicated slotting that electric initiating explosive device is equipped in mounting hole
Seat 6, the position of two sides is separately installed with one group of Signal plug 3 above cover board 2, and every group of Signal plug 3 is by two Signal plugs 3
Composition is connected by connecting rod 8 between two Signal plugs 3, and electric initiating explosive device private jack 6 by cable 7 respectively with letter
Number plug 3 is electrically connected, and electric initiating explosive device private jack 6 is fixedly connected by the second screw 9 and washer with pedestal 1, and Signal plug 3 leads to
It crosses nut 4 to be fixedly connected with cover board 2, passes through the first screw 5 and washer respectively for cover board 2 and bottom in the position at 2 four angles of cover board
Seat 1 is fixedly connected.
In order to guarantee that the insulating properties and environmental suitability of resistance measurement interface, the preferred embodiment of the present invention are pedestal 1
Inside is also filled with epoxy resin.
According to one embodiment of present invention, pedestal 1 is made of aluminium alloy, and connecting rod 8 is made of brass, cover board 2
For phenolic board, Signal plug 3 is PS-MT Signal plug.
The present invention makes Shi Xianyong connecting rod 8 and two Signal plugs 3 is joined together to form one group of Signal plug 3, then
Two groups of Signal plugs 3 are installed on cover board 2, and are tightened respectively with nut 4, electric initiating explosive device private jack 6 passes through the second screw 9
And washer is fixedly mounted on pedestal 1, and is connect Signal plug 3 with electric initiating explosive device private jack 6 with cable 7, in pedestal 1
On load onto cover board 2, cover board 2 is fixedly mounted on pedestal 1 by the first screw 5 and washer, since inside does not have encapsulating epoxy
When resin, solder joint and connecting rod 8 inside Signal plug 3 are easy to be influenced (such as vibration) by external factors, simultaneously because
The humidity of outside air be easy to cause between 3 inside solder joint of Signal plug the phenomenon that being easy electric discharge sparking, to guarantee resistance measurement
The insulating properties and environmental suitability of interface after being completed, need to pour into epoxy resin, epoxy resins insulation to the inside of pedestal 1
Intensity is before curing greatly fluid emulsion liquid with the dielectric strength of air, can will be filled out inside device with the increase of groundwater increment
It is full, after solidification to Signal plug 3 inside solder joint and connector 8 play fastening effect, while completely cutting off ambient humidity and changing pair
The influence of dielectric strength before 3 inside solder joint of Signal plug.
Then the first screw 5 is tightened until epoxy resin is fully cured.
Since electric initiating explosive device plug inside contact pin is acicular texture, and it is on the dedicated testing wire of traditional resistor test equipment
Dentation clip, is commonly called as crocodile clip, and the contact of the two is a little contact with face, and this contact can variation with contact position and folder
The variation of sub- tightness causes large effect to measurement result, and when the same tester measures every time clip folder
Point is different, will cause measurement result poor repeatability, and is measured using resistance measurement interface arrangement, by interface arrangement when use
Electric initiating explosive device private jack, realize with the close contact of electric initiating explosive device plug inside contact pin, since socket and plug contact pin is
Contact of the face with face improves the repeatability of resistance measurement this makes it possible to effectively reduce human error.
Working principle of the present invention is as follows:
Existing microresistivity survey equipment is using four-end method, and p-wire is also to adopt four-end method design and manufacture, to guarantee
Features described above, the interface arrangement for electric initiating explosive device resistance measurement are also provided with four Signal plugs 8, carry out electric initiating explosive device measurement
When, it is only necessary to four Signal plugs 8 are inserted into four jacks on microresistivity survey device panel, then by electrical fire work to be measured
Product are inserted into electric initiating explosive device private jack 6, and the constant-current source inside microresistivity survey equipment passes through two current feeds for electric current at this time
Electric initiating explosive device to be measured is passed to, and digital voltage is measured by constant-current source institute for electric current by two voltage leads in electrical fire work to be measured
Potential difference is formed by product, measurement result reaches the resistance of tested electric initiating explosive device, since two current feeds are in two voltages
Except lead, therefore influence of the contact resistance on current feed to measurement result can be excluded.
The above specific embodiment is described in detail for the essence of the present invention, but can not be to protection scope of the present invention
It is limited, it should be apparent that, under the inspiration of the present invention, those of ordinary skill in the art can also carry out many improvement
And modification, it should be noted that these improvement and modification are all fallen within the scope of the claims of the present invention.
