Definitions
- the present invention relates to an electrical contact with a foolproof device at the insertion of the contact into a contact module.
- the keying devices used for the electrical contacts are intended to ensure the correct orientation of the contacts in the cells of the contact holder modules or connector housings.
- the document FR 2 869 161 describes an electrical cage contact which is inserted into a connector housing cavity and which is provided with a foolproof device comprising at least one boss, made by cutting and stamping a side wall of the cage. contact to laterally exceed this cage, in order, by cooperating with a groove free passage of the boss, to perform a 360 ° coding of the contact to allow its insertion into the cell in a single angular position.
- This polarizing device positioned on a rear portion of the cage, however, allows to begin to insert the contact in a wrong angular position.
- such a coding device made by cutting and stamping a boss transverse to the insertion direction of the contacts in the cells of the connector housings receiving them, has sharp edges that could injure the joints of sealing arranged at the entrance of the cells and through which the contacts must pass during their insertion into the housings.
- the object of the present invention is to provide a contact element provided with a non-injurious coding device and for this purpose proposes a contact element comprising a front contact part intended to cooperate with a complementary contact part of an element. of complementary contact, a retention portion of the contact element in a connector housing and a keying boss, for which the keying boss consists of a tab, folded from the front to the back of the electrical contact element, and has a rounded front. More particularly, and, in order to achieve a non-aggressive return in a direction of extraction of the contact of its cell, on the folded leg, the free part rear of the tab is inserted at least partially into a bowl of the retention portion.
- the folded tab protrudes from the front of the cage so that the coding device prevents any beginning of incorrect insertion of the element. contact in its alveolus.
- FIG. 1 a perspective view of a first exemplary embodiment of the invention on a female contact element
- FIG. 2 a sectional view of a front part of the contact element of FIG. 1
- Figure 3 a sectional view of a second embodiment of the invention on a retention portion of a male contact element
- FIGS. 4A, 4B, 4C respectively flat views of a pre-cut blank, in perspective of the front part after folding of the sidewall and of the set in perspective of the contact element of FIG. 1 connected to a cable
- FIGS. 4A, 4B, 4C respectively flat views of a pre-cut blank, in perspective of the front part after folding of the sidewall and of the set in perspective of the contact element of FIG. 1 connected to a cable
- FIGS. 6A and 6B sectional views of an exemplary connector housing and a contact element according to the invention being inserted for FIG. 6A and extraction for FIG. 6B; in Figure 7 an embodiment of a contact according to the prior art.
- the invention is particularly adapted to an electrical contact element of the female electrical contact type 1, a general view of which is given in FIG. 4C, or to a male contact element 1 ', an overview of which is given in FIG. Figure 5C.
- the female contact element 1 comprises a front part 2 of cage-shaped contact incorporating a spring contact blade 16, shown in Figure 2, intended to cooperate with a portion of 2 "pin-shaped complementary contact of a complementary male electrical contact element 1a.
- the cage constitutes a retention portion 3 of the contact element in a connector housing 17.
- a female contact is in particular made in one piece from a cut blank, represented in FIG. 4A. flank then being folded to make the contact element.
- the contact element is intended to be crimped on a cable
- the male contact element 5 shown in FIG. 5C the latter comprises a spindle-shaped front contact portion 2 'intended to cooperate with a spring contact blade 16 arranged in the cage-shaped part of a complementary contact element 2 such as a female electrical contact element 1 described above.
- a complementary contact element 2 such as a female electrical contact element 1 described above.
- the male contact element can be cut bent or rolled and is covered with a cage, attached to the contact element, forming a retention portion 3 'of the male contact in a connector housing 17.
- the attached cage is made from a cut edge shown in Figure 5A, this side being then folded and inserted on the pin contact 2 '.
- the female contact element and the male contact element are provided with a keying boss 4 consisting of a tab 5, 6 folded from the front to the back of the contact element. electric and with a rounded front 7.
- FIG. 2 more particularly represents the embodiment of the boss according to the invention for a female contact element
- FIG. 3 more particularly represents an embodiment in the context of an attached cage intended to cover the central part of an element. male contact.
- the keying boss 4 is made from a lug 5 protruding from the front of the flank intended to achieve the female cage and, as shown in Figure 4A, this lug is folded from the front to the back of the contact element in a rounded to achieve the rounded front.
- the rounded front itself protrudes from the front of the cage once the tab folded so that, from the beginning of the insertion of the contact element into its cell, the operator can detect that the contact is not oriented in its correct position relative to the cell. This detection results from the fact that the advanced front 7 abuts against a wall of the cell devoid of a groove free passage of the boss.
- a rear free portion 8 of the tab is inserted at least partially in a bowl 9 constituted here by a cut-out of the retention portion 3.
- this cutout is from a stamping operation of a ceiling 11 of the cage, disposed opposite the spring contact blade 16, for guiding the complementary contact pin 2 'inserted into the female contact.
- the tab 6 comes from a cut-out of a wall 12 of the retention portion 3 and its rear free portion 8 is inserted at least partially into a bowl 9 'made to receive this free back part 8.
- the rear free portion of the folded tab of the male contact is embedded in the body of the cage to avoid any risk of attachment of the seal by the rear end of the tab constituting the boss when removing the contact of its socket .
- the frontal boss ensures precise positioning of the front of the contact in the cell at the expense of an increase in the amount of material consumed.
- FIGS. 4B and 5B show more particularly the cage parts of a female contact and reported cage for a male contact on which are formed the bosses according to the invention.
- a lug 19 disposed at the end of the wall opposite the wall carrying the boss 4 ensures the maintenance and positioning of the cage attached to the contact element.
- the tab 5 or 6 constitutes a longitudinal boss 4 and, in the case of the female contact, this boss 4 is disposed on a wall 12 opposite to a wall 14 carrying the spring contact blade 16 integrated in the part of retention 3.
- Figures 6A and 6B illustrate the insertion and extraction of a female contact as described above in a conector housing 17 of which only a central portion is shown.
- the connector housing 17 receives a grommet-type seal 20 provided with lips 21 intended to make the rear seal of the connector by applying to the cables 18 integral with the contacts 1, 1 '.
- the grommet 20 is received between two half-housings 17a, 17b constituting respectively the rear and the front of the connector housing 17 as known in the prior art.
- the receiving cells of the contacts are provided with grooves 22 for free passage of the bosses 4.
- the bosses 4 of the contact according to the invention are longitudinal bosses provided with a rounded front 7 and a rear free part driven into a housing 9, these The latter do not risk injuring the lips 21 at the insertion according to FIG. 6A or at the extraction according to FIG. 6B.
- the invention is not limited to the examples shown and, in particular, two bosses according to the invention can be provided on the side walls of the cage in the case of contacts with polarization at 180 °.
