US12352551 - Detonating cord depth locating feature

A detonator housing facilitates assembly of detonator components of a perforating gun. In an example, the detonator housing comprises a housing body configured for coupling to a charge tube of a perforating gun. A detonator receptacle is formed on the housing body for receiving a detonator. A detonating cord receptacle is formed on the housing body adjacent the detonator receptacle for receiving an end portion of a detonating cord in an overlapping relationship with the detonator. A detonating cord stop is formed on the detonating cord receptacle to limit an insertion depth of the detonating cord within the detonating cord receptacle.

The patent describes a detonator housing designed for use with a perforating gun, featuring a receptacle for a detonator and a separate receptacle for a detonating cord that overlaps with the detonator. A unique stop mechanism limits the insertion depth of the detonating cord while allowing visual confirmation of its proper placement.

Claim 1

A detonator housing, comprising: a housing body configured for coupling to a charge tube of a perforating gun; a detonator receptacle formed on the housing body for receiving a detonator; a detonating cord receptacle formed on the housing body adjacent the detonator receptacle, the detonating cord receptacle for receiving an end portion of a detonating cord in an overlapping relationship with the detonator received by the detonator receptacle; and a detonating cord stop formed on the detonating cord receptacle to limit an insertion depth of the detonating cord within the detonating cord receptacle, wherein the detonating cord stop covers a majority of an opening of the detonating cord receptacle, and a remaining portion of the opening is uncovered to visually confirm when the detonating cord is inserted into the detonating cord receptacle. a housing body configured for coupling to a charge tube of a perforating gun; a detonator receptacle formed on the housing body for receiving a detonator; a detonating cord receptacle formed on the housing body adjacent the detonator receptacle, the detonating cord receptacle for receiving an end portion of a detonating cord in an overlapping relationship with the detonator received by the detonator receptacle; and a detonating cord stop formed on the detonating cord receptacle to limit an insertion depth of the detonating cord within the detonating cord receptacle, wherein the detonating cord stop covers a majority of an opening of the detonating cord receptacle, and a remaining portion of the opening is uncovered to visually confirm when the detonating cord is inserted into the detonating cord receptacle.
