Description
Technical Field
The utility model mainly relates to the field of detonator detonating, in particular to a PCB board of an electronic detonator protective bridge wire.
Background
The patch bridge wire is a device for detonating a detonator, the bridge wire needs to be dipped with initiating explosive, and the patch bridge wire has the defects of easy deformation and insufficient dipping explosive in the dipping process.
Disclosure of Invention
In order to solve the technical problems, the utility model provides a PCB board of an electronic detonator protection bridge wire, which is realized by the following technical scheme:
a PCB board of an electronic detonator protective bridge wire comprising:
the bridge wire device is provided with two conductive arms, and the front ends of the two conductive arms are connected through a bridge wire;
the PCB is provided with a support part which is not smaller than the two side edges and the front edge of the two conductive arms at the front part, and the support part is provided with an avoidance port; the bridge wire device is arranged at the front part of the PCB, and the bridge wire is positioned between the front end of the supporting part and the avoidance port.
Preferably, the bridge wire is bent toward the dodge port.
Preferably, the two conductive arms are attached to the front of the PCB.
The utility model has the beneficial effects that: according to the PCB board of the bridge wire for protecting the electronic detonator, the bridge wire device is fixed on the PCB board, the appearance of the PCB board is larger than that of the bridge wire, and the bridge wire device is prevented from deforming in the process of dipping medicines; meanwhile, an avoidance port is formed in the PCB, and the bridge wire is in full contact with the bridge wire outside the front contact of the bridge wire and the explosive in the detonator, so that the bridge wire can be more stained with the explosive, and the combustion is more full.
Drawings
Fig. 1 shows an exploded structural schematic view of a PCB board of an electronic detonator protective bridge wire;
fig. 2 shows a schematic structural diagram of a PCB board of an electronic detonator protective bridge wire.
Detailed Description
The utility model is further described below with reference to the drawings and detailed description.
A PCB board of an electronic detonator protective bridge wire, as shown in fig. 1 and 2, comprising: the bridge wire device 1 is provided with two conductive arms 2, the front ends of the two conductive arms 2 are connected through a bridge wire 3, and the rear ends of the two conductive arms are fixed through a fixing block 4.
And the front part of the PCB circuit board 5 is provided with supporting parts 6 which are not smaller than the two side edges and the front edge of the two conductive arms 2, so as to form the outline of the protection bridge wire device. The support part 6 is provided with an avoidance port 7; the bridge wire device 1 is arranged at the front part of the PCB 5, and the bridge wire 3 is positioned between the front end 8 of the supporting part 6 and the avoidance port 7. The bridge wire 3 is bent towards the avoidance port, so that the bridge wire 3 can be ignited from the avoidance port 7, and after the bridge wire 3 is inserted into the detonator, the bridge wire 3 can be dipped into explosive in the detonator front and back, and the strength of the bridge wire device 1 is ensured. And the two conductive arms 2 are attached to the front part of the PCB 5, and the conductive arms 2 are subjected to patch welding with welding spots 9 of the PCB 5.
In the use process of the existing detonating device, the phenomena of easy deformation and even fracture of the bridge wire, the left conductive arm and the right conductive arm exist, the rejection rate is high, and the production efficiency is low. For solving above-mentioned technical problem, this special design of this patent improves the front end portion of extension PCB circuit board to with control two conductive arm 2 terminal surfaces looks parallel and level, protection bridging silk and control two conductive arm and do not receive the foreign matter directly collide with, beat a through-hole on the PCB that is close to bridging silk rear portion simultaneously to improve and be stained with the dose, help the gunpowder to ignite to detonate, improve the efficiency that the gunpowder once igniteed successfully.
