Definitions
- the present invention relates to the field of electrical connectors.
- JP-A-59 27 555 is known an electrical connection device for a printed circuit board having a support body and an elastic contact piece.
- the present invention relates in particular, but not exclusively, to an electrical connection device for the supply of logometers for motor vehicles.
- the main object of the present invention is to provide a simple and economical electrical connection device for reliably and quickly connecting two electrical members whose relative positioning can admit wide tolerances.
- the electrical connection provided between the branch of the contact piece housed in the channel and the pin engaged in sliding in the latter can admit wide tolerances between the two bodies to be connected in the direction of the axis of the channel. Furthermore, the bending of the first branch of the contact piece allows a wide positioning tolerance between the two members to be connected, in any direction transverse to the axis of the channel.
- the elbow of the contact piece connecting the two branches rests against the edge of the channel to avoid any deformation of the contact piece during the insertion of the pin into the channel.
- the contact piece of electrically conductive wire has four "W" branches, two side branches having a free end intended to be fixed to the second member and two shorter, central branches, housed in the channel of the support body, to come into contact with the spindle, the elbows between each of the lateral branches and the adjacent central branch resting against the edge of the channel of the support body.
- This support body 10 comprises, as indicated above, a support base 20 and a channel 50.
- the support base comprises two generally parallel lateral webs 22, 24 interconnected by a median web 26 which is perpendicular to them.
- the free edges 23, 25, 27 of the three aforementioned webs 22, 24, 26, the most distant from the channel 50 are coplanar and determine the bearing surface of the base 20 on the second member to be connected, for example a printed circuit .
- the base 20 is provided with a wall 30 which carries the channel 50.
- the wall 30 extends substantially parallel to the bearing plane delimited by the edges 23 , 25 and 27 of sails 22, 24 and 26.
- the channel 50 is formed by a sleeve 51 having a through central bore 52 whose axis 53 extends perpendicular to the support plane delimited by the free edges 23, 25 and 27.
- the sleeve 51 is carried by the aforementioned wall 30.
- the wall 30 On the outside of the sleeve 51 the wall 30 is provided with two through holes 31, 32, substantially diametrically opposite with respect to the axis 53 of the channel.
- the orifices 31, 32 are intended to receive the branches of the contact piece 100 shown in Figures 6, 7 and 8 connected to said second member.
- the orifices 31, 32 are flared at 33, 34 at the level of the surface 35 of the wall 30 directed towards the channel 50.
- the edge of the channel 50 opposite the support base 20 has two grooves 54, 55 substantially diametrically opposite with respect to the axis 53.
- the grooves 54, 55 are intended to receive the contact piece as will be explained by the after.
- the plane of symmetry of the grooves 54, 55, parallel to the web 26 of the base passes through the axes 36, 37 of the orifices 31, 32 formed in the wall 30.
- edge of the channel 51 opposite the support base 20 is rounded to facilitate the insertion of the pin 150 shown in Figure 9 in the channel.
- the support base 20 is provided, opposite the bore 52 of the channel 50, with a latching lug 40.
- This lug 40 is intended to serve as a point of attachment for the branch or branches of the contact piece 100 housed in the bore 52 of the channel in order to maintain the contact piece 100 on the support body 10 in the form of a unitary assembly.
- the lug 40 is integral with the internal surface 38 of the web 26.
- the plane of symmetry of the lug 40 passes through the axis 53 of the bore 52 of the channel.
- the lug 40 has a hooking surface 41 parallel to the support plane defined by the free edges 23, 25 and 27, that is to say perpendicular to the axis 53.
- the lug 40 also has a engagement surface 42 opposite to the web 26. The engagement surface 42 diverges from the web 26 in approach to the attachment surface 41 on which it ends.
- the axis 53 of the bore 52 of the channel 50 is perpendicular to the bearing surface delimited by the edges 23, 25, 27 of the base 20.
- the axis 53 of the bore 52 of the channel 50 may be oblique on the support plane delimited by the edges 23, 25 and 27 of the base 20.
- This contact piece 100 is made of electrically conductive wire.
- the contact piece 100 has 4 branches 110, 120, 130 and 140 folded in the general shape of W. More specifically, the contact piece 100 comprises two lateral branches 110, 140 parallel to each other, the free end 111, 141 of which is intended to be fixed to the second member to be connected, for example a printed circuit. Preferably, said free ends 111, 141 of the lateral branches 110, 140 are intended to be engaged in holes in the printed circuit to be soldered thereon.
- the contact piece 100 also has two shorter central branches 120, 130.
- the central branches 120, 130 are connected together by an elbow 122.
- one of the central branches 120 is connected to the adjacent lateral branch 110 by an elbow 112 while the other central branch 130 is connected to the adjacent lateral branch 140 by an elbow 142 symmetrical with the above-mentioned elbow 112.
- the parallel, central branches 120, 130 are intended to be engaged in the bore 52 of the channel 50 in order to come into contact with the spindle 150. During such engagement of the branches 120, 130 in the bore 52 of the channel, the elbow 122 comes into the hooking position on the lug 40, to retain the contact piece 100 on the support body 10.
- the lateral branches 110, 140 are engaged in the orifices 31, 32 of the wall 30 connecting the 'support base 20 to channel 50.
- the elbows 112, 142 are engaged respectively in the grooves 54, 55 provided at the edge of the channel.
- the distance D shown diagrammatically in FIG. 6 corresponding to the projection parallel to the longitudinal axis of the branches 110, 120, 130, 140, of the distance separating the bottom of the concave surface of the elbow 122 from the bottom of the concave surface of one or other of the elbows 112 or 142 symmetrical must be equal to the clearance close to the distance separating on the support body 10 the bottom of the grooves 54, 55 of the attachment surface 41 of the lug 40.
- each of the central branches 120, 130 of the contact piece 100 is provided near the elbow 112, 142 which connects it to a lateral branch 110, 140 of a camber 123, 133 facilitating the contact between these branches 120, 130 and the pin 150 engaged in the channel.
- the spindle 150 shown in Figure 9 is formed of a cylindrical barrel 151
- the two ends 152, 153 of the spindle 150 intended to be engaged one in one of the members to be connected, the other in the bore 52 of the channel are preferably tapered.
- the end 152 is tapered in a frustoconical shape while the other end 153 is tapered with a spherical cap.
- the spindle 150 is moreover provided, substantially at mid-length with a projecting peripheral rib 154 limiting the engagement of the spindle 150 in both of the member to be connected and of the support body. 10.
- the electrical connection device comprising in combination the support body 10 and the contact piece 100 which have just been described, it is first necessary to place the contact piece 100 on the support body 10.
- the ends 111, 141 of the lateral branches 110, 140 of the contact piece are placed opposite the orifices 31, 32 and pushed into them.
- the elbow 122 and the shorter central branches 120, 130 then penetrate into the bore 52 of the channel 50.
- the elbow 122 comes to bear against the engagement surface 42 and slides thereon inducing a elastic deformation of the central branches 120, 130.
- the central branches 120, 130 return to their rest position.
- the contact piece 100 is then hung on the support body 10 by means of the elbow 122 and the hooking lug 40.
- the support body 10 and the contact piece 100 form a unitary assembly.
- the contact piece 100 is held firmly on the printed circuit by its lateral branches 110, 140, which allows a simple and quick disconnection of the pin 150 and side branches 120, 130 without deterioration of the latter.
- the electrical connection device which has just been described makes it possible to reliably connect two electrical members, for example a printed circuit and a logometer of motor vehicles, despite large positioning tolerances between these members.
- the tolerances between these members in a direction parallel to the axis 53 of the bore of the channel are made up by inserting more or less the pin 150 in the bore.
- the positioning tolerances between these same two members in all directions transverse to the axis 53 of the bore 52 of the channel are caught up by elastic bending of the lateral branches 110, 140 of the contact piece.
- the axis 53 of the channel 52 may be perpendicular to the support plane delimited by the free edges 23, 25, 27, the axis 53 may be oblique on this plane d 'support.
- the contact piece 100 has 4 branches folded in W.
- the contact piece 100 could comprise only two branches bent in a U, of which a first branch 110 would have a free end 111 intended to be fixed to the printed circuit, while being able to flex freely, and of which a second branch 120, shorter , would be intended to be housed in the channel 50 of the support body 10 to come into contact with the pin 150.
- the contact piece 100 could comprise 3 branches folded in Z, generally parallel to each other, of which a first branch 110 would have a free end 111 intended to be fixed to the printed circuit and the second and third 120, 130, shorter, would be intended to be housed in the channel 50 of the support body 10 to come into contact with the spindle 150.
- the support body 10 is provided with a single channel 50 and associated with a single contact part 100.
- the support body 10 may if necessary have a plurality of channels 50 and be associated with the same number of contact parts 100. Such an arrangement proves to be advantageous for supplying a multipole accessory.
- the support body 10 is produced by plastic molding.
