Integrated wiring gun and method
An improved perforating gun with novel endplates is disclosed along with a corresponding method of assembly. The endplate includes a base with a first end separated from a second end separated by a curved sidewall centered around a longitudinal axis and a set of tube tabs flexibly coupled to the base and extending from the second end. Each of the set of tube tabs has a retaining lip and is generally oriented in a direction of the longitudinal axis. The endplate may include an optional carrier tab with an integrated alignment pin. Selected embodiments may also include a zero-tension connector with a sliding contact mounted within a cavity of a housing, a through-wire connected to the sliding contact. The novel endplate reduces the cost and complexity of manufacture and installation.
1. An endplate comprising:
a base with a first end separated from a second end by a curved sidewall, which is centered around a longitudinal axis of the base;
a plurality of tube tabs flexibly coupled to the base and extending from the second end, wherein each of the set of tube tabs is generally oriented in a direction of the longitudinal axis, and wherein each of the set of tube tabs comprises a retaining lip;
a plurality of structural supports fixedly coupled to the base and extending from the second end, along the set of tube tabs; and
an alignment pin projecting radially outward from the curved sidewall.
2. The endplate of claim 1 , further comprising a plurality of carrier tabs recessed into the curved sidewall.
3. The endplate of claim 2 , wherein at least one of the plurality of carrier tabs comprises a flange projecting radially outward relative to the curved sidewall.
4. The endplate of claim 1 , wherein the plurality of structural supports is generally oriented in the direction of the longitudinal axis.
5. The endplate of claim 4 , wherein the plurality of structural supports comprises a plurality of curved sidewalls arranged around an aperture at the second end of the base.
6. The endplate of claim 4 , wherein the plurality of tube tabs is interspersed between the plurality of structural supports.
7. The endplate of claim 6 , wherein the plurality of tube tabs and the plurality of structural supports are arranged around an aperture in the second end of the base.
8. The endplate of claim 1 , wherein the plurality of tube tabs is asymmetrically disposed around an aperture at the second end of the base.
