- - Figure 5 is a perspective view similar to that of Figure 2 which illustrates a second embodiment of a connection device according to the teachings of the invention according to which the terminal and the connection eyelet are made in a single piece by cutting, folding and rolling the tubular body of the connection eyelet;
- FIG. 6 is a sectional view similar to that of Figure 4 which illustrates a third embodiment of a connection device according to the teachings of the invention according to which the washer of the terminal and the upper flange of the eyelets are fixed to each other by welding;
- FIG. 7 is a view similar to that of Figure 6 which illustrates a fourth embodiment of a connection device according to the teachings of the invention according to which the terminal and the connection eyelet are fixed to each other by crimping;
- FIG. 8 is a section through a vertical plane of the connection eyelet of Figure 7, before its fixing by crimping on the washer of the connection terminal.
- the electrical connection device 10 consists essentially of a tubular eyelet 12 and a connection lug 14.
- the tubular eyelet 12 is a part produced by deep drawing in an electrically conductive metal sheet so that it comprises a cylindrical tubular lower body 16 of circular generator and vertical axis XX and an upper flange 18 which extends radially outwards from from the upper end of the lower tubular body 16.
- the lower end section 20 of the tubular body 16 is rectilinear.
- the terminal 14 is a part produced by cutting and folding in a conductive metal sheet.
- It comprises a horizontal lower part 22 in the form of a generally circular contour connection washer and which comprises a central hole 24 intended to receive the tubular lower body 16 of the eyelet 12.
- the washer 22 is delimited by an annular upper face 26 and by an opposite annular lower face 29.
- connection washer 22 extends vertically upwards, here by way of example, by a tab 30 which is itself bent at 90 degrees to extend horizontally and longitudinally by an upper horizontal connection tab 32 which is also in the form of a washer with for example a central claw hole 34 with a vertical axis YY.
- the tabs 30 and 32 can also extend in the horizontal plane of the washer 22 or according to any other orientation depending on the applications.
- the tubular lower body 16 of the eyelet 12 is designed to be received in a vertical through-hole and complementary 36 formed in an insulating support 38 which is for example a wall of an insulating cover d '' an electromagnetic starter switch (not shown).
- the insulating support 38 is delimited by two upper 40 and lower 42 horizontal faces.
- the through hole 36 is of frustoconical shape by widening in the lower face 42.
- the washer 28 of the terminal 14 is sandwiched between the lower annular face 19 of the flange 18 of the eyelet 12 and a portion opposite the upper face 40 of the insulating support 38.
- the end section lower 20 of the tubular body 16 of the eyelet 12 is crimped in the lower part 44 of the hole 36.
- the eyelet 12 receives a central thread 46 centrally, the upper end section 48 of which is welded by brazing 50 to the internal concave cylindrical wall 15 of the tubular body 12.
- the eyelet 12 and the lug 14 are made in one piece by deep drawing, cutting and folding.
- the upper flange 18 and the washer 22 constitute a single piece.
- the electrical connection device 10 consists of a single piece in which the electrical continuity between the eyelet 12 and the connection terminal 14 is ensured from the outset, that is to say independently of the subsequent fixing. of the device 10 on the insulating support 38.
- the tubular body 16 of the eyelet 12 vertically from top to bottom in the hole 36 until the lower horizontal face 19-28 common to the collar ⁇ -washer 22 is in abutment on the horizontal upper face 40 of the insulating support 38.
- the lower section 20 of the lower tubular body 16 is crimped as before.
- the eyelet 12 is made in one piece with the lug 14, by cutting, folding and rolling of the sheet until, for example, obtaining '' a complete tubular body with a helical connection zone 54.
- the horizontal upper part of the eyelet 12 constituting its upper flange 18 and the washer 22 is "incomplete" and is for example here in the form of three branches radially outside and evenly distributed at 120 degrees.
- tubular eyelet 12 and the lug 14 are again produced initially in the form of two separate and distinct components similar to those illustrated in FIGS. 2 and 3, which are then fixed to the one to the other to form a one-piece assembly before mounting and fixing the connection device 10 on the insulating support 38.
- the fixing is carried out by welding the upper flange 18 onto the washer 22.
- electrical welding is carried out between the lower face 19 of the flange 18 and the portion facing the upper face 26 of the washer 22.
- the tubular eyelet 12 is initially presented with its two straight upper and lower end sections, that is to say without any crimping.
- It also comprises a collar forming an external radial shoulder 56 which constitutes a support, axially downward, for the lower face 29 of the washer 22, while the upper section passes through the hole 24 and extends axially upwards above of the upper face 26 in order to be able to undergo a crimping operation to ensure the fixing of the washer 22 to the eyelet 12.
- the upper end of the eyelet 12 is shaped into the outer flange 18.
- the two parts 12 and 14 are thus made integral and are in electrical contact to constitute a connection device within the meaning of the invention.
- the assembly is very rigid and allows the eyelet 12 and the terminal 14 to be made from materials of different thickness and / or composition.
- the hole 36 can be modified at its upper end for the passage of the collar 56, or else it is the latter which is in axial support on the portion opposite the upper face 40.
