Abstract
Abstract Electric terminal box, including connecting pins (6, 6', 6") extending from the bottom surface of the terminal box housing (1) in direction towards the open portion of the housing (1), arranged to facilitate connection of electric wires inserted into the terminal box, also arranged to establish electrical connection with tubular connecting means (14), located in a corresponding configuration at the electrical switch, power point or similar component intended to be arranged in a position mainly surrounded by the housing (1), the component, when inserted into the terminal box establishing electrical contact via the connecting pins (6, 6', 6") to the electrical wires inserted into the terminal box. The connecting pins (6, 6', 6") are preferably attached to a base plate (5), rotatably mounted adjacently to the internal bottom surface of the housing (1), and arranged lockable in desired angular rotary positions in relation to the housing (1) by means of a locking member (10, 11), co-acting with the housing (1). The component to be attached, and electrically connected, is preferably arranged with a locking means (15, 16), co-acting with the housing (1) or a separate co-acting member (9), in order to facilitate securing of the component in desired relative position to the internal bottom surface of the housing (1), the members (9, 15, 16) preferably being arranged only to facilitate unlocking by use of a special purpose tool.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
149 words
An electrical terminal box comprising: a housing having an internal bottom surface, an opposing open end, and at least one opening for the insertion of an electrical wire; a base plate rotatably mounted within said housing adjacent to its internal bottom surface; locking means for locking said base plate in a desired angularly rotated position in relation to the housing; a plurality of parallel connecting pins extending outward from the base plate toward the housing open end, each pin having a longitudinally extending slot adapted to receive an inserted electrical wire; clamping locking means for locking an electrical wire after insertion into said slot; and an outer insulating body removably mounted within the housing open end over the base plate, having tubular connecting means for snugly fitting over each of said connecting pins for establishing an electrical connection with electrical wires that are inserted in the connecting pin slots.
Claim 2
Dependent Claim
149 words
An electrical terminal box comprising: a housing having an internal bottom surface, an opposing open end, and at least one opening for the insertion of an electrical wire; a base plate rotatably mounted within said housing adjacent to its internal bottom surface; locking means for locking said base plate in a desired angularly rotated position in relation to the housing; a plurality of parallel connecting pins extending outward from the base plate toward the housing open end, each pin having a longitudinally extending slot adapted to receive an inserted electrical wire; clamping locking means for locking an electrical wire after insertion into said slot; and an outer insulating body removably mounted within the housing open end over the base plate, having tubular connecting means for snugly fitting over each of said connecting pins for establishing an electrical connection with electrical wires that are inserted in the connecting pin slots.
Claim 3
Dependent Claim
36 words
The terminal box of claim 1 wherein the insulating body includes locking means for locking the insulating body and other components within the housing, in a desired position in relation to the housing internal bottom surface.
Claim 4
Dependent Claim
65 words
The terminal box of claim 2 wherein the insulating body locking means comprises a stud having an external screw thread for insertion into a threaded hole passing through said insulating body, said bottom plate, and said housing, and a locking member is screwed on to the outward end of said stud, said locking member being screwable only by the use of a special purpose tool.
Claim 5
Dependent Claim
30 words
The terminal box of claim 1, 2 or 3 wherein at least two of said connecting pins are internally electrically connected to each other by means of a connecting member.
Claim 6
Dependent Claim
39 words
The terminal box of claim 4 wherein the connecting pins are arranged in such a configuration that the insulating body can only be attached by its respective tubular connecting means in a predetermined position relative to the connecting pins.
Claim 7
Dependent Claim
25 words
The terminal box of claim 5 wherein the base plate has a mainly disc-shaped circular configuration from which at least one peripheral portion is removed.
Claim 8
Dependent Claim
152 words
An electrical terminal box comprising: a housing having an internal bottom surface, an opposing open end, and at least one opening for the insertion of an electrical wire; a base plate rotatably mounted within said housing adjacent to its internal bottom surface; locking means for locking said base plate in a desired angularly rotated position in relation to the housing; a plurality of parallel connecting pins extending outward from the base plate toward the housing open end, each pin having a hole extending transversely to its length axis for receiving an electrical wire; clamping means for locking an electrical wire after insertion into said connecting pin hole; and an outer insulating body removably mounted within the housing open end over the base plate, having tubular connecting means for snugly fitting over each of said connecting pins for establishing an electrical connection with electrical wires that are inserted in the connecting pin holes.
Claim 9
Dependent Claim
152 words
An electrical terminal box comprising: a housing having an internal bottom surface, an opposing open end, and at least one opening for the insertion of an electrical wire; a base plate rotatably mounted within said housing adjacent to its internal bottom surface; locking means for locking said base plate in a desired angularly rotated position in relation to the housing; a plurality of parallel connecting pins extending outward from the base plate toward the housing open end, each pin having a hole extending transversely to its length axis for receiving an electrical wire; clamping means for locking an electrical wire after insertion into said connecting pin hole; and an outer insulating body removably mounted within the housing open end over the base plate, having tubular connecting means for snugly fitting over each of said connecting pins for establishing an electrical connection with electrical wires that are inserted in the connecting pin holes.
