Electric accessory connector for cap lamp battery

Claim 2

Miner''s cap lamp apparatus comprising, in combination, a storage battery having a battery top member removably secured thereto, a miner''s cap lamp, electrical conductor means connected through the battery top member to positive and negative terminals of the battery for energizing said cap lamp, electrical connector means including an accessory receptacle mounted on the upper side of the battery top, fastening means for solidly securing both the accessory receptacle and the battery top member to an upper side portion of the battery, an accessory plug detachably supported on the receptacle, and electrical conductor means attached to the fastening means for supplying current through the accessory receptacle and plug to an electrically energized device independently of operation of the miner''s cap lamp.

Claim 3

A structure according to claim 1 in which the battery top includes a locking member for releasably securing the accessory plug in the plug receptacle.

Claim 4

A structure according to claim 1 in which the accessory plug includes a recessed casing, a slide member fixed to the inner side of the recessed casing and having a pair of spaced apart angularly shaped negative contact portions, a resilient positive contact element secured to the slide member in electrically insulated relation therewith, and said plug receptacle being formed with a positive contact engageable by the positive contact element of the accessory plug and a negative contact element protectively enclosed in the plug receptacle and engageable by one of said angularly shaped negative contact portions of the accessory plug.

Claim 5

A structure according to claim 3 in which the negative contact element of the accessory plug receptacle is contained in a plate member and the plate member is secured by threaded fastenings which are electrically connected to the battery terminals.

Claim 6

A structure according to claim 1 in which the receptacle is formed with a recessed base portion having a negative contact support block located therein, and said negative contact being supported in the receptacle above the recessed base portion with a yieldable extremity projecting into the recessed portion into engagement with the contact supporting block and in the path of travel of the said moveable contact element of the accessory plug.

Claim 7

A structure according to claim 7 in which the plug receptacle includes a trapping plate mounted on the receptacle base, said plate having opposite edges thereof located in spaced relation and above the said slideways, and said trapping plate being formed with a negative contact slot for yieldably supporting said negative contact element of the plug receptacle.

Claim 8

A structure according to claim 6 in which the trapping plate is formed with a second slot located in front of the said negative contact element of the plug receptacle and having a resilient trapping element extending into the recessed portion of the plug receptacle at a point in front of and below the said negative contact element of the plug receptacle.

Claim 9

Electrical connector means for a miner''s cap lamp battery of the class having positive and negative electrodes, a battery casing for containing the electrodes and an electrolyte, and a baTtery top mounted on the casing above the electrodes, and having a miner''s cap lamp conductor located therethrough, said connector means comprising a plug receptacle component secured to the battery top and having enclosed positive and negative contacts electrically connected to the said positive and negative electrodes, and an accessory plug detachably mounted in the receptacle in electrically connected relationship thereto, said plug receptacle being formed with slideways communicating with its negative contact elements, said accessory plug being constructed with a negative contact element which is moveable along the slideways into electrically connected relationship with the said negative contact of the plug receptacle, said slide-ways being of L-shaped cross section and said negative contact element of the accessory plug being formed with a pair of spaced apart angularly formed edges which are of a size and shape for slidably engaging in said slideways.

Claim 10

Electrical connector means for a miner''s cap lamp battery of the class having positive and negative electrodes, a battery casing for containing the electrodes and an electrolyte, and a baTtery top mounted on the casing above the electrodes, and having a miner''s cap lamp conductor located therethrough, said connector means comprising a plug receptacle component secured to the battery top and having enclosed positive and negative contacts electrically connected to the said positive and negative electrodes, and an accessory plug detachably mounted in the receptacle in electrically connected relationship thereto, said plug receptacle being formed with slideways communicating with its negative contact elements, said accessory plug being constructed with a negative contact element which is moveable along the slideways into electrically connected relationship with the said negative contact of the plug receptacle, said slide-ways being of L-shaped cross section and said negative contact element of the accessory plug being formed with a pair of spaced apart angularly formed edges which are of a size and shape for slidably engaging in said slideways.
