Definitions
- the subject invention relates to a high current electrical socket terminal for such uses as in automotive high current connectors.
- a solid brass material is machined to include either a pin and socket at one end, and a wire connecting bore at the opposite end.
- a wire to be terminated is first stripped and then inserted in the bore, whereupon the wire connecting portion is crushed to crimp the material forming the bore around the wire.
- the wire size varies the crimp quality could be affected by the increase or decrease of the void within the wire crimp area by the wire.
- the smaller the conductor the more thoroughly the wire crimp area must be crushed in order to terminate the wire.
- An object of the invention then is to provide a more inexpensive electrical socket terminal which can also be used with such high current applications.
- the objects of the invention have been accomplished by providing an electrical socket terminal for high current applications, where the terminal comprises a front socket portion for mating with the pin and a wire connecting portion at the rear thereof.
- the socket terminal is characterized in that the terminal is comprised of an inner spring contact having a lower constricted portion, interferringly inserted into a constricted portion of the outer contact body, whereby electrical contact is made between the spring contact and the contact body.
- an electrical socket terminal is shown generally at 2 comprised of a front contacting section 4 an intermediate section 6 and a wire terminating section 8.
- the socket terminal 2 is comprised of an outer contact body 10 integral with the wire contacting section 8, together with an inner spring contact 12 which forms the electrical connection with the pin portion.
- the outer contact body 10 is stamped from a flat sheet of material and rolled into a cylindrical configuration having an axially extending seam at 14. The cylinder is held in a closed position by way of interlocking tabs 16 and 18 which prevent the radial expansion of the cylindrical body.
- the outer contact body 10 includes a constricted portion at 20 formed by a transition at 22.
- the outer contact member 10 further includes 3 raised sections 24 (only two of which are shown in Figure 3) formed by a sheared portion at 25 which forms a stop edge at 26, as shown in Figure 4.
- the raised sections 24 are formed to be radially equidistant with the outer diameter of the front section 11, as best shown in Figure 4.
- the terminal further comprises a sheared band portion 28 which is formed to be radially equidistant with the front section 11, as best shown in Figure 4, and includes a sheared edge 30 in opposing relation to the edge 26.
- the outer contact member 10 further includes three raised sections 32, which as shown in Figure 4 are formed to extend outside the radius of the cylindrical portion 11 such that a forwardly facing edge 34 extends beyond the band portions 28 for locking the terminal within a corresponding housing, as will be explained in greater detail herein.
- the outer terminal portion 10 includes a plurality of locking fingers 36 having sheared side edges 38, the sheared edges 38 allowing the fingers to be formed inwardly towards the center line of the contact as will be described in greater detail herein.
- Each of the fingers 36 is formed with a peripherally extending groove 40, thereby defining a locking shoulder 42, as shown in Figure 4.
- the spring contact 12 is formed from a flat sheet of material and rolled into a generally cylindrical configuration having a longitudinal seam at 45.
- the spring contact 12 further includes a plurality of contact arms 46 inwardly directed at 48 to form an inner contact surface at 50.
- the individual contact arms 46 are generally suspended between a forward band portion 52 and a rearward band portion 54, the forward band portion 52 including a front edge at 56.
- the band portion 54 is integrally connected with a constricted portion 58 via a transition section 60 as best shown in Figure 5.
- Three raised sections generally shown at 62 are located at the transition section 60 and are raised to an outward extent equal to the outer diameter of the band portion 54 as best shown in Figure 6.
- the raised portion 62 is defined by a sheared portion 63 thereby forming a locking edge 64 as best shown in Figure 6.
- Sections 66 are located within the constricted portion and are directed inwardly as best shown in Figure 6.
- the inner contact portion 12 includes a conical lead-in section shown generally at 70.
- the inner spring contact 12 is inserted with the conical leadin portion 70 inserted through the individual fingers 36 of the cylindrical portion 11 ( Figure 4).
- the inner spring contact 12 includes an outer surface 59 ( Figure 6) on the constricted portion 58 which interferes with an inner surface 21 ( Figure 4) of the constricted portion 20 and further movement of the inner socket portion 12 is by way of interference longitudinal movement between the surfaces 59 and 21.
- the inwardly directed portions 66 on the inner socket contact 12 can be used with an insertion tool positioned inside of the socket contact 12 for moving the spring contact 12 into its fully inserted position.
- the inner spring contact 12 is inserted to a position where the edge 64 ( Figure 6) abuts the forwardly facing edges 27 ( Figure 4) whereby the inner spring contact is prevented from further rearward movement by way of the contact between the edges 64 and 27.
- the individual fingers 36 are crimped downwardly, radially inwardly to the position shown in Figure 2, which positions the locking edge 42 over the front edge 56 of the forward band portion 52 of the inner spring contact 12, as shown in Figure 2.
- an outer locking band 80 can now be snapped over the assembled socket contact, the band 80 being locked on the transition section 20 of the outer contact portion between edges 26 and 30 ( Figure 4).
- the locking band 80 includes a plurality of locking lances 82 having end locking edges 84.
- the socket terminal can be formed with a wire insulation crimping portion 8 and yet still be used with high current applications.
- the outer band portion 10 can be formed of a relatively thick material preferably a copper alloy, whereas the inner contact spring 12 can be formed from a thin material such as a copper-nickel.
- the band portions 52 and 54 are radially held in position within the outer contact body thereby providing rigidity to the inner contact spring.
- the individual contact arms are also provided with a rigidity in that they are suspended between surfaces 27 and 42 ( Figure 4) thereby resisting the inner movement of the individual contact arms.
