Abstract
The utility model discloses a coupling card for a detonating tube, a primer and a primacord. A detonating tube mounting groove (2) and a primacord mounting groove (3) are provided on the card body (1), and cross one another; a grab to prevent the detonating tube from detachment is provided at the edge of the primacord mounting groove (3). The utility model is properly designed structurally. As the utility model adopts the mode of clipping (insertion) to join the detonating tube, the ends of cap wires of the primer and the primacord together to ensure the joining angles to be more than 70 DEG C and come to 90 DEG C; accordingly, the utility model is free from the limitation of detonation direction, prevents failure of detonation, and has the characteristics of handiness, quick operation, and safe and reliable use.
Description
Technical field
The utility model relates to a kind of detonator, detonator and primacord and connect card.
Background technology
Detonator, detonator are a kind of novel blasted materials, have propagation of explosion rapidly, accurately, safe, cheap characteristics.Particularly in directional blasting and large-scale mine explosive applications, has incomparable advantage.Therefore be used widely in the bursting work at home and abroad.At present, the bind mode of detonator, detonator and primacord is to be wrapped on the primacord with the linea angulata tail end of adhesive plaster with its detonator, detonator, because it is necessary consistent that detonator, detonator and the connection angle of primacord are greater than 70 ° and propagation of explosion direction, therefore the mode of twining with adhesive plaster is not only operated loaded down with trivial details, and be not easy to reach the requirement that connects angle, easily produce the phenomenon of miss-firing, poor stability.
The purpose that the utility model belongs to promptly produces thus, proposes a kind of detonator, detonator and primacord and connects card.It is safe and reliable, convenient to operation that this connects card, effectively avoided the phenomenon of miss-firing.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: on the card body detonator mounting groove and primacord mounting groove are set, described detonator mounting groove and primacord mounting groove cross one another, and have the grab that prevents the detonator slippage at the notch position of detonator mounting groove.
The utility model reasonable in design.Because it adopts the mode that snaps in (insertion) that the linea angulata tail end and the primacord of detonator, detonator are bound up, guaranteed that it connects angle and reaches 90 ° greater than 70 °, be not subjected to the restriction of propagation of explosion direction, avoided the miss-firing generation of phenomenon, have characteristics convenient to operation, safe and reliable.

The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
Embodiment 1
As Fig. 1 in conjunction with shown in Figure 2: present embodiment be at axial position detonator mounting groove 2 is set by the square card body 1 of plastic production, radially the position is provided with primacord mounting groove 3, this two groove crosses one another.The bottom of detonator mounting groove 2 is that circular configuration, its top are " V " shape structure.Has the grab 4 that prevents the primacord slippage at the notch position of primacord mounting groove 3.When present embodiment uses, be right-angled intersection after detonator and primacord are installed respectively and connect, it connects angle is 90 °.
As Fig. 3 in conjunction with shown in Figure 4: present embodiment be at axial position detonator mounting groove 2 is set by the microscler card body 1 of plastic production, radially the position is provided with primacord mounting groove 3, this two groove crosses one another.Be provided with grab 4 that prevents the detonator slippage and the spring leaf 5 that is mated at the notch position of primacord mounting groove 3.Be right-angled intersection after detonator and primacord were installed when present embodiment used and connect, it connects angle is 90 °.
Claims (4)
1, a kind of detonator, detonator and primacord connect card, it is characterized in that: on card body (1), detonator mounting groove (2) and primacord mounting groove (3) are set, described detonator mounting groove (2) and primacord mounting groove (3) cross one another, and have the grab (4) that prevents the detonator slippage at the notch position of detonator mounting groove (2).
2, detonator according to claim 1, detonator and primacord connect card, it is characterized in that: described detonator mounting groove (2) and primacord mounting groove (3) are right-angled intersection.
