Description
Technical Field
The utility model relates to an initiating explosive device makes technical field, concretely relates to novel connection structure of detonating cord and detonator.
Background
The plastic detonating cord is made up by using Ethan or Hexon as medicine core, using chemical fibre or cotton thread or hemp thread as internal wrapping material and coating thermoplastic plastics on its external layer. In addition, the mechanical sensitivity and the thermal sensitivity of the explosive core of the detonating cord are lower than those of the detonator, so that the detonating cord has high safety performance and is widely applied to presplitting blasting, water hole blasting and high-temperature rock blasting in open blasting.
In the connection of the detonating cord with the detonator, the detonating detonator should be connected more than 15cm from the end of the detonating cord, considering that the end of the detonating cord may be affected with moisture or be damaged by mechanical action. Although the traditional connection process ensures reliable explosion propagation, due to the explosion propagation directionality, the reserved detonating cord is easy to reject explosion and remains in an explosion area, so that great potential safety hazards are buried in the explosion area.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
In order to overcome the defects in the prior art, a novel connecting structure of a detonating cord and a detonator is provided so as to solve the problems in the background art.
(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides a novel connection structure of detonating cord and detonator, including detonating cord and detonator, detonating cord's end sets up reservation portion, the end of detonator sets up detonator leg wire, detonating cord's end overlap joint is on detonator's terminal detonator leg wire, detonating cord and detonator leg wire are tied up fixedly through insulating sticky tape after reservation portion is looped.
Further, the reserved portion is larger than 15 cm.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
the utility model provides a novel connection structure of detonating cord and detonator when guaranteeing reliable biography and explode, also detonate the detonating cord of loophole, avoids exploding the back initiating explosive device and remains, eliminates the potential safety hazard in exploding the district.
Drawings
Fig. 1 is a schematic diagram of the structure of the detonating cord of the present invention after looping.
1-a detonating cord; 11-a reserved portion; 2-a detonator; 21-detonator leg wire; 3-insulating adhesive tape.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The novel connecting structure of the detonating cord and the detonator shown in fig. 1 comprises the detonating cord 1 and the detonator 2, wherein a reserved part 11 is arranged at the tail end of the detonating cord 1, a detonator leg wire 21 is arranged at the tail end of the detonator 2, the tail end of the detonating cord 1 is lapped on the detonator leg wire 21 at the tail end of the detonator 2, and the detonating cord 1 and the detonator leg wire 21 are bound and fixed through an insulating adhesive tape 3 after being looped at the reserved part 11.
As a preferred embodiment, the reserved portion 11 is larger than 15 cm.
The utility model provides a novel connection structure of detonating cord and detonator when guaranteeing reliable booster, also detonates the detonating cord of looper, avoids exploding the back priming sytem and remains, eliminates the potential safety hazard in exploding the district.
When the driven detonating cord is connected, the detonating cord is lapped on the detonator, the tail end of the reserved detonating cord is larger than 15cm, and when detonation waves propagate from the detonator to the detonating cord, the section of detonating cord and the direction of the propagating explosion form 180 degrees (larger than 90 degrees), so that the detonation waves cannot propagate to the direction of the residual detonating cord, the phenomenon of explosion rejection occurs, initiating explosive is remained in an explosion area, and potential safety hazards are easily brought.
Here, the reserved portion 11 of the detonating cord 1 is looped, so that the reserved portion 11 of the detonating cord 1 is also lapped on the detonator leg wire 21 of the detonator 2 after looping, and then is bundled by the insulating tape 3, and further, during detonating, the reserved portion 11 of the remaining detonating cord 1 and the tail end of the detonating cord 1 can form an annular blasting network, and the annular blasting network is characterized in that detonation waves can propagate from two directions. When detonation waves are propagated to the detonating cord from the detonator 2, the reserved part 11 of the looped detonating cord 1 is detonated while ensuring reliable propagation, so that residual initiating explosive after explosion is avoided, and potential safety hazards of an explosion area are eliminated.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
