Detonator tail wire connecting device and connecting method

Abstract

The invention discloses a detonator tail line connecting device and method. The connecting device comprises a connecting plug, a connecting receptacle and a female bushing, wherein the female bushingis nested on a tail line and can rotate relative to the tail line; a first tool bit connected with a detonator control chip is arranged on the connecting plug, and a tail line connecting line with aninsulating layer is arranged on the connecting receptacle; the female bushing comprises a connecting threaded section, a truncated cone-shaped transition section and a pressing section sequentially. The detonator is transported separately from an outer line, the connecting plug of the detonator and the connecting receptacle of the tail line end are connected through a female thread during assembly, the matching part of the connecting plug and the connecting receptacle is extruded by the transition section of the female bushing, so that the tool bit cuts the insulating layer of the tail line, and the detonator and the tail line are connected. Accordingly, transportation safety can be improved, transportation cost can be reduced, and on-site assembly of the detonator and the tail line is simple and rapid to operate and high in reliability.

Description

Technical field [0001] The invention relates to the technical field of electronic detonator initiation, in particular to a detonator tail wire connection device and connection method. Background technique [0002] When the existing detonator is produced, the detonator, tail wire and tail wire clamp are shipped together, which will cause the problem of large volume and heavy weight of the entire product; and in the transportation process, the safety of the detonator and the tail wire at the same time cannot be guaranteed. Transportation costs will also increase. At the same time, there are currently some wiring terminals: one is by manual crimping, such as plastic metal wiring clips, which are prone to loose buttons and open circuits, and the waterproof effect is not good; the other is through elastic sheets When contact is made, the degree of compression cannot be guaranteed, and the contact point is prone to oxidation, and no signal can be communicated. [0003] Therefore, the e...

Problems solved by technology

[0002] When the existing detonators are produced, the detonators, tail wires and tail wire clamps leave the factory together, which will cause the problem of large size and heavy weight of the whole product; Shipping costs will also increase

At the same time, there are currently some terminal blocks: one is through manual crimping and buckling, such as plastic hardware terminal clips, which are prone to loose buckles, resulting in open circuits, and the waterproof effect is not good; the other is through elastic sheets. Contact, the degree of compression cannot be guaranteed, and the contact point is prone to oxidation, and the signal cannot be communicated
