Abstract

In general, in one aspect, embodiments relate to a detonator assembly that includes a detonator housing that includes a detonating cord receptacle and a detonator receptacle, a detonator seated within the detonator receptacle, a detonating cord seated within the detonating cord receptacle side-by-side the detonator, and a grounding clip that extends lengthwise along a substantial portion of the detonator housing, where the grounding clip extends beyond an axial end of the detonator housing.

First claim

What is claimed is:

1 . A detonator assembly comprising:
a detonator housing comprising a detonating cord receptacle and a detonator receptacle, a detonator seated within the detonator receptacle; a detonating cord side-by-side the detonator and seated within the detonating cord receptacle; and a grounding clip that extends lengthwise along a substantial portion of the detonator housing, wherein the grounding clip comprises a single piece of conductive metal having an elongated body portion with two consecutive inward bends on an upper end that lead to a ninety-degree bend towards an axial end of the detonator housing.

2 . The detonator assembly of claim 1 , wherein the grounding clip comprises two flexible locking tabs extending out from either side of an elongated body portion of the grounding clip.

3 . The detonator assembly of claim 1 , wherein an upper end of the grounding clip wraps around a radial protrusion of the detonator housing.

4 . The detonator assembly of claim 1 , wherein the detonator housing comprises a raised box with a pin hole for receiving an electrical pin.

5 . The detonator assembly of claim 1 , wherein the detonator housing comprises a plurality of non-contiguous peripheral portions circumferentially spaced around a central axis of the detonator housing.

6 . The detonator assembly of claim 1 , wherein the detonator housing comprises a click-lock fastener unitarily formed as part of the detonator housing.

7 . The detonator assembly of claim 1 , wherein the detonator housing comprises a collet and a lug configured to seat within openings of a charge tube.

8 . The detonator assembly of claim 1 , wherein the detonator housing comprises plastic.

9 . The detonator assembly of claim 1 , wherein the detonator housing comprises a skeletonized body to reduce an amount of material occupied by the detonator assembly.

10 . The detonator assembly of claim 1 , wherein the detonator receptacle and the detonating cord receptacle each comprise one or more stops to prevent over-insertion of either or both the detonating cord and the detonator.
