Technical Field

The utility model belongs to the technical field of the blasting, especially, relate to a quick grafting device of detonator generating line.

Background

In the actual blasting use process of the electronic detonator, the electronic detonator is communicated with a detonator initiation control device (commonly called an initiator) through a group of conducting wires, and the initiator performs operations of registration, decryption, permission release, delay setting, charging, initiation and the like on the electronic detonator in a blasting hole. In the blasting field, a multi-detonator networking is usually adopted for blasting to achieve an ideal blasting effect, and the multi-detonator is simultaneously connected in parallel to the group of leads connected with the blasting device through the quick jointing clamp, so that the group of leads becomes a 'trunk line' (commonly called a bus). Because the blasting operation site is dangerous, the bus needs to be dragged to a relatively safe area and then connected to an initiator for operations such as initiation, and therefore, a special bus connecting device needs to be designed on the initiator to ensure that the bus connecting operation is convenient, quick and reliable each time.

At present, two connection mechanism modes are commonly available in the industry, one mode is an electrical power wiring mode of 'external bolt and nut connector', and the other mode is 'socket-pin + connecting wire + clip'.
