3. The battery connector as claimed in claim 2, wherein two outmost ends of the fixing slot extend downward to form a pair of inserting slots, two ends of the bottom edge of the base plate extend downward to form a pair of fixing strips inserted in the corresponding inserting slots.
4. The battery connector as claimed in claim 1, wherein a protrusion protrudes upward from a front of a bottom face of the fastening cavity and has a middle spaced from the bottom face of the fastening cavity to define an inserting cavity therebetween, a front end of the base portion of the terminal is inserted in the inserting cavity.
5. The battery connector as claimed in claim 4, wherein a top edge of each propping portion protrudes forward to form a fastening portion slightly inclined upward, a pair of fastening fillisters are opened in a top inside of the fastening cavity and each extending longitudinally to penetrate through the rear surface, the fastening portions are respectively fastened in the fastening fillisters.
6. The battery connector as claimed in claim 1, further comprising a cover which has a base board, a front of a bottom surface of the base board extending downward to form two buckling pillars spaced from and aligned with each other along a transverse direction thereof, a rear of the bottom surface of the base board extending downward to form two locating pillars spaced from and aligned with each other along the transverse direction thereof, the insulating housing defining two locating fillisters spaced from each other and each passing through the top surface and the rear surface for receiving the corresponding locating pillars therein, and two buckling grooves spaced from each other and each passing through a bottom surface and the front surface for hooking a free end of the corresponding buckling pillars therein.
7. The battery connector as claimed in claim 1, wherein the top surface and the front surface of the insulating housing are connected with each other by an arc face.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A female coupling half for use with a male coupling half, said male coupling half includes a male valve, said female coupling half comprising: a female valve; a valve lock shaft affixed to said valve and movable therewith; a lock piston; said valve lock shaft includes a recess; said lock piston includes a plurality of apertures; a plurality of detents reside respectively in said plurality of apertures of said lock piston; and, said detents interengaging said recess securing said male and female valves in open position.
2. A female coupling half for use with a male coupling half as claimed in claim 1, said female half further comprising: a lock sleeve, and said lock sleeve restraining said detents from radial movement.
3. A female coupling half for use with a male coupling half as claimed in claim 2, said female half further comprising: a sliding sleeve; and, a spring operable between said lock sleeve and said sliding sleeve.
4. A female coupling half for use with a male coupling half as claimed in claim 3 wherein said valve lock shaft includes an exterior, a hollow inner core, and a passageway interconnecting said exterior and said hollow inner core.
5. A female coupling half for use with a male coupling half as claimed in claim 4 wherein said female valve is affixed to said valve lock shaft by a threaded interconnection.
6. A female coupling half for use with a male coupling half as claimed in claim 4 wherein said female valve includes an end portion and an opening for receiving said male valve member.
7. A female coupling half for use with a male coupling half as claimed in claim 6 wherein said end portion is flared.
8. A female coupling half for use with a male coupling half, said male coupling half includes a male valve, said female coupling half comprising: a female valve; a valve lock shaft having a circumferential recess therein; a lock piston; said lock piston includes a plurality of circumferentially spaced apertures; a plurality of detents residing, respectively, in each of said circumferentially spaced apertures; a lock sleeve forcibly restraining said detents in said recess of said valve lock shaft when said male and female coupling halves are coupled together; and, said detents removably residing in said circumferential recess of said valve lock shaft when said male and female coupling halves are uncoupled.
9. A female coupling half for use with a male coupling half, said male coupling half includes a male valve and a male body, said female coupling half comprising: a female valve; a retainer for securing a seal; said female valve includes a lip and a recess; said lip engages said seal when said coupling halves are disconnected; and, during engagement of said coupling said male body engages said retainer followed by said male valve engaging said recess and said lip of said female valve such that said seal is spaced apart from said lip of said female valve partially opening said female valve.
