Abstract
Abstract Electrical terminals having the same shape are provided and which can be integrated. Two latch flanges 7 are provided projecting in symmetrical positions on the circumference of an eye-shaped connection region 5, and hook portions 10 into which the companion latch flanges 7 enter are formed in positions adjacent to the latch flanges 7 to the rear in the clockwise direction. Projections 12 are formed by shearing the surface of the connection region 5 upwards, inwards from the latch flanges 7, and to the front of these are formed lock holes into which the companion projections 12 fit. The connection region 5 of one terminal 1 is laid over the top surface of the connection region 5 of another terminal 1 concentrically, then the upper terminal is turned clockwise, whereupon the latch flanges 7 engage into the companion hooks 10; the projection 12 of the lower terminal 1 fits in the companion lock hole 13 so that the two terminals 1 are integrated.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
224 words
An electrical terminal provided with a connection region which is generally aligned with a plane and has an aperture therein, and an arm to which an end of an electrical wire is connected in use, wherein the terminal is provided with angularly spaced male and female latching members formed in the connection region, the female latching member having a portion which is offset from the plane to define a gap therewith which is open on at least one radially extending side, the male latching member being receivable into the gap via the open radial side of the female latching member of an overlying second of said terminals on relative angular movement therebetween to hold the overlying connection regions together, one of said male and female latching members having a projection which engages the other of said male and female latching members of the overlying terminal to tighten the interconnection of the terminals, said connection region further including a lock projection having a generally radial locking edge extending out of the plane thereof and an angularly spaced and corresponding lock aperture having a generally radial locking side, the locking edge of the lock projection being engageable with a locking side of a lock aperture of the overlying second of said terminals to prevent a reverse relative angular movement therebetween on engagement of said latching members.
Claim 2
Dependent Claim
224 words
An electrical terminal provided with a connection region which is generally aligned with a plane and has an aperture therein, and an arm to which an end of an electrical wire is connected in use, wherein the terminal is provided with angularly spaced male and female latching members formed in the connection region, the female latching member having a portion which is offset from the plane to define a gap therewith which is open on at least one radially extending side, the male latching member being receivable into the gap via the open radial side of the female latching member of an overlying second of said terminals on relative angular movement therebetween to hold the overlying connection regions together, one of said male and female latching members having a projection which engages the other of said male and female latching members of the overlying terminal to tighten the interconnection of the terminals, said connection region further including a lock projection having a generally radial locking edge extending out of the plane thereof and an angularly spaced and corresponding lock aperture having a generally radial locking side, the locking edge of the lock projection being engageable with a locking side of a lock aperture of the overlying second of said terminals to prevent a reverse relative angular movement therebetween on engagement of said latching members.
