Definitions
- the invention relates to a contact spring with a connection part for an electrical conductor and a contact part with a spring leg base and spring leg extending therefrom for contacting a plug-in contact, and with a spring leg base made from a stamped and bent part made of sheet metal.
- the contact part enclosing box-shaped, designed as an over-spring locking sleeve with a bottom wall, two side walls, each with a spring arm cut out from the side wall, bent inwards and resting on a spring leg, a top wall divided by a production-related noise slot and a wall cut out from one wall locking spring arm extending in the longitudinal direction of the locking sleeve and bent outwards.
- Such contact springs are generally known, for example from DE-PS 35 46 762.
- the locking sleeve essentially has the function of a reinforcing or over-spring which is intended to increase the spring force.
- the over-spring known from DE-PS 35 46 762 is provided on the two side walls in each case in the longitudinal edge region of the box shape with free cuts and on a front box web with separating cuts, so that over-spring arms extend tongue-like to the front towards the plug-side end are formed, which are bent towards each other inwards and rest on the contact spring.
- a detent spring arm is cut out in the bottom wall of the over-spring and bent outwards, which serves to lock the contact spring in a contact chamber of a housing.
- the invention is based on the object, in the case of a contact spring of the type mentioned at the outset, in the form of the latching sleeve as an over-spring for spring force support and in doing so avoiding impairing its protective function as far as possible.
- the spring arms are formed only by separating cuts running essentially transversely to the longitudinal direction of the locking sleeve, that these separating cuts run from the side walls to the longitudinal edge area at the transition to the bottom wall and end there in that the respective spring arm in this
- the longitudinal edge area remains connected to the locking sleeve, and that the respective spring arm extending from this connection transversely to the longitudinal direction of the locking sleeve is bent inward about a bending line lying in this longitudinal edge area and running parallel to the longitudinal direction and in the direction of the longitudinal direction of the locking sleeve .
- the Uberfederarme the locking sleeve are formed only by separating cuts, so that the locking sleeve is not mechanically weakened and optically opened by cuts, but maintains a largely closed cost profile.
- the contact spring is thus well protected against damage, for example by pointed tools, by the locking sleeve.
- the closed box profile also results in a mechanically stable locking sleeve, which is particularly important for the protection of a contact spring locking sleeve which has not yet been accommodated in a contact chamber of a housing and is still exposed to the rough workshop operation.
- the large dimensional stability of the locking sleeve achieved by the closed box profile leads to a larger load capacity of the locking sleeve in different Directions, ie the closed locking sleeve is more torsion-resistant in comparison to a locking sleeve that is more open due to free cuts and thus less loadable and absorbs more forces.
- optimal spring force support is achieved in a contact spring according to the invention due to the advantageous arrangement of the spring arms.
- the spring arms are formed only by separating cuts, but remain connected to the locking sleeve in the longitudinal edge region, that is to say extend in the direction of the width of a side wall of the locking sleeve transversely to its longitudinal direction, the spring base is formed on the bending line from the stable base region, whereby defined spring ratios can be achieved.
- the spring arms there is also sufficient space for the design of a spring arm and thus for the dimensioning of the spring force, since the base width of the spring arms is structurally not restricted and expand to a sufficient extent between the plug-side and the connection-side end of the locking sleeve can.
- the maximum base width of the spring arms is limited by the maximum width of one side wall of the locking sleeve.
- a longer separating cut which is directed perpendicularly to the longitudinal direction of the latching sleeve and extends close to the longitudinal edge at the transition from the respective side wall into the ceiling wall, is also advantageous in order to form a spring arm plug-side end of the locking sleeve farther than the longer separating cut, relatively short separating cut, which is also directed perpendicular to the longitudinal direction of the locking sleeve and parallel to the longer separating cut and only something extends into the respective side wall, and a third separating cut connecting these two separating cuts at their ends is provided, which is arranged exclusively in the respective side wall of the locking sleeve and extends obliquely to the longitudinal direction of the locking sleeve.
- spring arms are created in which the arrangement, design and position of the force application can be optimally adjusted in height to the spring legs of the contact spring.
- the oblique separating cut expediently forms a kind of run-on slope on the pre-bent spring-over arms for better mounting of the contact spring in the locking sleeve.
- Each spring arm advantageously has a perforation.
- a perforation in the spring arms enables a fine adjustment of the spring force.
- the size, position and shape of the perforation influence the force and travel conditions of the spring arms.
- it is advantageous if the perforation is arranged in the longitudinal edge area.
- the force-displacement relationships can be positively influenced.
- the bending line can be influenced more.
- a spring leg of the contact spring is formed on a longitudinal edge facing the bottom wall of the locking sleeve with a rag torn out in the direction of the other spring leg as a spring opening contour.
- the longitudinal slot of the ceiling wall of the locking sleeve extends eccentrically in relation to its width, so that the ceiling wall extends into a narrow partial area and a wide section is separated, and if the detent spring arm is provided in the wide section.
- the detent spring arm is thus arranged on the ceiling wall, which is open anyway, so that no further walls of the detent sleeve have to be cut free for the detent spring arm.
- FIG. 1 shows a top view of the contact spring
- FIG. 2 shows a side view of the contact spring
- FIGS. 3 to 6 show four views of the sides of a locking sleeve
- FIG. 7 shows the locking sleeve according to FIG. 6 partially in section
- FIG. 8 shows the locking sleeve in cross section
- the unit contact spring locking sleeve in a top view or in a side view.
- the contact spring 1 consists of a connecting part 2 designed, for example, as a crimp connection, to which a contact part 3 is connected with a spring leg base 4 with a U-shaped cross section, which has a base 5 and two side walls 6.
- the contact part 3 has two spring legs 7 and 8 for contacting a plug contact.
- These feather legs run - starting from the spring leg base - first towards each other up to a contact zone 9, at which one spring leg 8 is formed on one longitudinal edge with a tab 10 torn out in the direction of the other spring leg 2 as a spring opening contour.
- the spring legs 7 and 8 diverge from this contact zone 9 in a funnel shape.
- the two side walls 6 of the spring leg base 4 are each formed on the free longitudinal side facing the viewer of FIG. 1 with a recess 11 for later fixing of the locking sleeve.
- the locking sleeve 12 shown in FIGS. 3 to 6 is made from a stamped and bent part made of sheet metal and is formed into a part with a rectangular cross section with a bottom wall 13, two side walls 14 and a top wall 15, which is divided by a longitudinal slot 16 due to the manufacturing process.
- 3 and 5 show views of the two side walls 14, FIG. 4 the view of the base wall 13 and FIG. 6 the view of the top wall 15 of the locking sleeve 12, which can be seen in FIG. 6, that the longitudinal slot 16 of the ceiling wall extends eccentrically in relation to its width, so that the ceiling wall 15 is separated into a narrow section 17 and a wide section 18.
- the wide partial area 18 is approximately twice as wide as the narrow partial area 17.
- a locking spring arm 19 extending in the longitudinal direction of the locking sleeve 12 is provided in the wide partial area 18 of the top wall 15. This is used to lock the contact spring-locking sleeve unit in a contact chamber of a housing, is cut out of the wide partial area 18 and - as can be seen in FIGS. 3, 5 and 6 - is bent outwards on the bending line 23.
- the width of the Rastfed 'ER armes equal to the full width of the wide portion 18 of the Deckenwa ⁇ du ⁇ g 15, so that the locking spring arm 19 extends in width from the longitudinal slot 16 to a longitudinal edge 20 of the locking sleeve 12 at the transition from the ceiling wall 15 to the right side wall 14.
- the detent spring arm 19 is formed with an inwardly embossed bead 22 which begins somewhat below the bending line 23 and extends centrally in the longitudinal direction of the detent spring arm 19 up to its free end face 24.
- the top wall 15 of the locking sleeve 12 has a small area associated with the spring leg base 4 of the contact spring 1 near the end facing the connecting part 2 of the contact spring 1 free cut 25 extending over the full width of the ceiling wall 15.
- a narrow web 29 which is bent outwards by about 90 and which ensures correct insertion of the contact spring-locking sleeve unit into a contact chamber of a housing.
- the latching sleeve 12 is designed as an over-spring for spring force support.
- a spring arm 41 is cut out of each side wall 14 and bent inwards.
- the two spring arms 41 are - as can be clearly seen in the figures - arranged, constructed and manufactured in the same way and - in relation to the central longitudinal axis of the locking sleeve or the bottom wall 13 - arranged symmetrically in the side walls 14.
- the spring arms 41 are formed only by separating cuts which run essentially transversely to the longitudinal direction of the locking sleeve 12.
- the spring arms 41 are arranged at a distance from the plug-side edge 42 of the locking sleeve 12 within the protective zone 26.
- a longer separating cut 43 is provided here, which is perpendicular to the longitudinal direction of the locking sleeve 12 is directed at one end to close to the longitudinal edge 20 or 32 at the transition from the respective side wall 14 into the ceiling wall 15 and at the other end is guided around the rear longitudinal edge 44 or 45 and - as can be seen in FIG is - ends in the bottom wall 13.
- a second, relatively short separation cut 46 which is also perpendicular to the longitudinal direction of the locking sleeve and parallel to the longer separation cut, is provided from the plug-side end of the locking sleeve 12 even further than the longer separating cut 43, but only somewhat around the rear longitudinal cut edge 44 or 45 around the bottom wall 13 and the respective side wall 14. Furthermore, in the respective side wall 14 there is also a third separating cut 47 connecting the two separating cuts 43 and 46 at their ends, which runs obliquely to the longitudinal direction of the locking sleeve 12.
- spring arms 41 are formed with a plan shape similar to a right-angled triangle, the separating cuts 43,
- Each spring arm 41 which extends from this connection transversely to the longitudinal direction of the locking sleeve in the direction of the locking sleeve width Z onto the front longitudinal edge 20 or 32, is now around a spring located in the rear longitudinal edge region, parallel to the longitudinal direction and in the direction of the longitudinal direction Locking sleeve extending bending line 48 (FIG. 8) bent inward, which forms the spring base B with a base width H.
- This base width is here - since it extends in the longitudinal direction of the locking sleeve - as can be easily seen, not structurally limited to the locking sleeve width Z.
- a radius 49 is formed, the force application P of the spring arms 41 optimally with the radius zone 49 on the spring legs 7, 8 of the contact spring 1, specifically - with respect to the central axis - off-center on the spring legs and advantageously in the area opposite the tab 10 of the spring leg 8. This can also be seen in FIG. 9.
- the oblique separating cut 47 also serves as a run-up slope when inserting the contact spring into the locking sleeve.
- each spring arm 41 has a hole 50, which is arranged here in the rear longitudinal edge region approximately in the middle of the base width H of a spring arm 41 and both approximately in the respective side wall 14 and somewhat in the bottom wall 13 reaches in.
- Locking sleeve 12 made of stainless steel is largely closed and thus very stable and is used with particular advantage where, in addition to a protective and locking function of the locking sleeve, a force-supporting effect of the contact spring by spring arms is important, e.g. for contacts in tin design with higher contact force.
