An energetic material initiation device having a receiver assembly and an initiator assembly that includes an electronic initiator and a pellet assembly with an energetic material. The receiver assembly is configured to be coupled to a firing circuit. When the firing circuit is to be armed, the initiator assembly can be pressed into a socket in the receiver assembly to electrically couple the receiver assembly and the initiator assembly. A method for mounting an energetic material initiation device to a firing circuit is also provided.

An energetic material initiation device comprising: an initiator assembly that is configured to be received at least partially within a receiver assembly, the initiator assembly including an initiator housing, an electronic initiator, a pellet assembly and a plurality of initiator terminals, the initiator housing defining a recess into which the pellet assembly is received, the initiator housing including an insertion guide and a locking member, the initiator terminals being electrically coupled to the electronic initiator and extending through the initiator housing, the pellet assembly including an energetic material;wherein the insertion guide is configured to be engaged to the receiver assembly to align the initiator assembly to the receiver assembly; andwherein the locking member that is configured to engage the receiver assembly in a snap-fit manner. 2. The energetic material initiation device of claim 1, wherein each of the initiator terminals defines an anchoring aperture, wherein the initiator housing is formed of plastic and wherein a portion of the plastic is received through the anchoring apertures. 3. The energetic material initiation device of claim 1, wherein the initiator housing comprises a base, which defines a bottom side of the initiator housing, and a sidewall that is fixed to the base, and wherein a portion of at least one of the initiator terminals is disposed parallel to the bottom side of the base. 4. The energetic material initiation device of claim 3, wherein a distal end portion of the at least one of the initiator terminals is abutted against the bottom side of the base. 5. The energetic material initiation device of claim 4, wherein a proximal end portion of the at least one of the initiator terminals extends through the base and wherein an intermediate portion of the at least one of the initiator terminals wraps around the base to couple the proximal end portion to the distal end portion. 6. The energetic material initiation device of claim 5, wherein the intermediate portion of the at least one of the initiator terminals is disposed in a volume that is smaller than a volume that is circumscribed by an outside surface of the sidewall. 7. An energetic material initiation device comprising: a receiver assembly with a receiver and a plurality of receiver terminals, the receiver including a base and an upstanding wall member, the base and the upstanding wall member cooperating to form a socket, the upstanding wall member defining a first locking member, the receiver terminals extending through at least one of the base and the upstanding wall member; andan initiator assembly at least partially received in the socket, the initiator assembly including an initiator housing, an electronic initiator, a pellet assembly and a plurality of initiator terminals, the initiator housing defining a recess into which the pellet assembly is received, the initiator housing including a second locking member, the initiator terminals being electrically coupled to the electronic initiator and extending through the initiator housing, the pellet assembly including an energetic material;wherein the first and second locking members engage one another in a snap-fit manner to inhibit the initiator assembly from being withdrawn from the socket; andwherein the receiver terminals engage the initiator terminals to electrically couple the electronic initiator and the receiver terminals. 8. The energetic material initiation device of claim 7, wherein one of the receiver terminals and the initiator terminals resiliently engages the other one of the receiver terminals and the initiator terminals. 9. The energetic material initiation device of claim 8, wherein the initiator housing comprises a base member, which defines a bottom side of the initiator housing, and a sidewall that is fixed to the base member, and wherein a portion of at least one of the initiator terminals is disposed parallel to the bottom side of the base member. 10. The energetic material initiation device of claim 9, wherein a distal end portion of the at least one of the initiator terminals is abutted against the bottom side of the base member. 11. The energetic material initiation device of claim 7, wherein one of the first and second locking members includes an outer longitudinal wall and a first abutting wall, the outer longitudinal wall extending in a direction that is parallel to a central axis of the socket and tapering inwardly toward the central axis, the abutting wall extending in a direction that is generally perpendicular to the central axis of the socket, and wherein the other one of the first and second locking members includes a second abutting wall that abuts the first abutting wall when the first and second locking members are engaged to one another. 12. The energetic material initiation device of claim 7, wherein the upstanding wall member defines a first insertion guide, the initiator housing defines a second insertion guide, and wherein the first and second insertion guides are engaged to one another to align the initiator assembly to the receiver. 13. The energetic material initiation device of claim 12, wherein one of the first and second insertion guides comprises a groove having sidewalls, at least a portion of the sidewalls tapering inwardly toward one another. 14. The energetic material initiation device of claim 13, wherein the other one of the first and second insertion guides comprises a rib with lateral sides, and wherein at least a portion of the lateral sides are inwardly tapered to match the inwardly tapered portion of the sidewalls of the groove. 15. The energetic material initiation device of claim 7, wherein the initiator assembly further comprises a cover member that is directly coupled to the initiator housing. 16. The energetic material initiation device of claim 15, wherein the cover member is crimped to a flange that extends about the initiator housing. 17. An energetic material initiation device comprising: a receiver assembly with a receiver and a plurality of receiver terminals, the receiver formed of plastic and molded onto the receiver terminals to fixedly couple the receiver terminals to the receiver, the receiver having a socket, a first insertion guide and a first locking member; andan initiator assembly fully inserted in the socket, the initiator assembly including an initiator housing, an electronic initiator, a pellet assembly and a plurality of initiator terminals, the initiator housing defining a recess into which the pellet assembly is received, the initiator housing including a second insertion guide and a second locking member, the initiator terminals being electrically coupled to the electronic initiator and extending through the initiator housing, the pellet assembly including an energetic material;wherein the first and second insertion guides are engaged to one another to align the initiator assembly to the receiver;wherein the first and second locking members are automatically and mutually engaged responsive to the full insertion of the initiator assembly into the socket to inhibit the initiator assembly from being withdrawn from the socket; andwherein the receiver terminals engage the initiator terminals to electrically couple the electronic initiator and the receiver terminals. 18. The energetic material initiation device of claim 17, wherein the first and second locking members engage one another in a snap-fit manner. 19. The energetic material initiation device of claim 18, wherein one of the receiver terminals and the initiator terminals resiliently engages the other one of the receiver terminals and the initiator terminals. 20.
