Abstract
Abstract A first connector unit 30 has electrical terminals 31 exposed at a rear upper surface portion. A second connector unit 40 has an insertion mouth 46 into which the first connector unit 30 is inserted as shown in Figure 6. The first connector unit 30 enters freely-rotatable accommodation case 41 in the second connector unit 40 upon insertion. After insertion, electrical terminals 31 of first connector unit 30 oppose but are spaced . apart from electrical terminals 42 of second connector unit 40. By applying pressure P to the first connector unit 30, that unit is rotated as shown in Figure 7 and pressure contact is brought about between electrical terminals 31 and electrical terminals 42.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
97 words
An electrical connection system, in which connection of electrical terminals of first and second connector units involves insertion of the first connector unit into a mouth of the second connector unit, characterised in that, after insertion of the first connector unit into the mouth of the second connector unit, pressure contact between electrical terminals of the first and second connector units is brought about by rotation of the first connector unit in a direction substantially at a right angle to the direction of insertion of the first connector unit into the mouth of the second connector unit.
Claim 2
Dependent Claim
97 words
An electrical connection system, in which connection of electrical terminals of first and second connector units involves insertion of the first connector unit into a mouth of the second connector unit, characterised in that, after insertion of the first connector unit into the mouth of the second connector unit, pressure contact between electrical terminals of the first and second connector units is brought about by rotation of the first connector unit in a direction substantially at a right angle to the direction of insertion of the first connector unit into the mouth of the second connector unit.
Claim 3
Dependent Claim
107 words
An electrical connector arrangement, comprising first and second connector units, the second connector unit having a mouth into which the first connector unit is inserted for establishing connection of electrical terminals of the first and second connector units, characterised in that the first and second connector units are adapted such that when the first connector unit is inserted in the mouth of the second connector unit, rotation of the first connector unit in a direction substantially at a right angle to the direction of insertion of the first connector unit into the mouth brings about pressure contact between electrical terminals of the first and second connector units.
Claim 4
Dependent Claim
107 words
An electrical connector arrangement, comprising first and second connector units, the second connector unit having a mouth into which the first connector unit is inserted for establishing connection of electrical terminals of the first and second connector units, characterised in that the first and second connector units are adapted such that when the first connector unit is inserted in the mouth of the second connector unit, rotation of the first connector unit in a direction substantially at a right angle to the direction of insertion of the first connector unit into the mouth brings about pressure contact between electrical terminals of the first and second connector units.
Claim 5
Dependent Claim
58 words
An electrical connection system as claimed in claim 1., or an electrical connector arrangement as claimed in claim 2, as the case may be, wherein the first and second connector units are such that when pressure contact between the electrical terminals of the first and second connector units is brought about, the units are locked in that condition.
Claim 6
Dependent Claim
71 words
An electrical connection system or an electrical connector arrangement, as the case may be, as claimed in claim 2, wherein the first and second connector units are such that when the units are in a locked condition, an unlocking operation can be effected which restores the first connector unit to the disposition thereof after insertion into the mouth of the second connector unit, but before rotation of the first connector unit.
Claim 7
Dependent Claim
106 words
An electrical connection system, or an electrical connector arrangement, as the case may be, as claimed in claim 4, wherein the second connector unit comprises a freely rotatable casing into which the first connector unit enters upon insertion into the mouth of the second connector unit, a locking lever, the casing and locking lever being so adapted as to engage one another, to establish the locked condition, when the firstconnector unit is rotated to bring about pressure contact between electrical terminals of the first and second connector units, and a push button operable to disengage the locking lever from the casing, to effect the unlocking operation.
Claim 8
Dependent Claim
70 words
An electrical connection system, or an electrical connector arrangement, as the case may be, as claimed in any preceding claim, wherein electrical terminals of the firstconnector unit are provided on a surface towards that end of the first connector unit which is for insertion first into the mouth of the second connector unit, and electrical terminals of the second connector unit are provided internally thereof remotely from the mouth thereof.
Claim 9
Dependent Claim
135 words
An electrical connection system , or an electrical connector arrangement, as the case may be, as claimed in any preceding claim, wherein the first connector unit is provided with an L-shaped groove along a side thereof, and the second connector unit is provided with a pin type projection which projects into the mouth thereof, such that when the first connector unit is inserted into the mouth of the: second connector unit, the projection engages the groove (the horizontal arm of the "L"), to guide the first connector unit into the mouth, and such that when the first connector unit is fully inserted into the mouth, rotation of the first connector unit engages the projection with the bent portion of the groove (the vertical arm of the "L") to prevent withdrawal of the first connector unit.
Claim 10
Dependent Claim
63 words
An electrical connection system, or an electrical connector arrangement, as the case may be, as claimed in any preceding claim, wherein the second connector unit is provided with a window through which a predetermined part of the second connector unit can be seen when, but only when, pressure contact has been established between the electrical terminals of the first and second connector units.
Claim 11
Dependent Claim
75 words
An electrical connection system , or an electrical connector arrangement, as the case may be, as claimed in any preceding claim, wherein the first connector unit has a cover for covering the electrical terminals thereof, the first and second connector units being adapted such that when the first connector unit is inserted into the mouth of the second connector unit, the cover of the first connector unit is opened to expose the electrical terminals thereof.
Claim 12
Dependent Claim
42 words
An electrical connection system, or an electrical connector arrangement, as the case may be, as claimed in any preceding claim, wherein the second connector unit has a cover which covers the mouth thereof, when the first connector unit is not inserted therein.
