Description

TECHNICAL AREA

The present invention relates to an electrical contact, in particular a flat contact or a fork contact, with a first conductive element, with at least one electrical connecting element for contacting the first conductive element and designed for contacting a feedable second conductive element and with at least one holding member for holding the electrical connection element or elements on the first conductive element, the first conductive element having at least one T-shaped incision in the surface facing the feedable second conductive element, the electrical connection element or elements having a first contact section for contact with the first conductive element in the T-shaped incision and a second contact portion for contact with the feedable second conductive element outside of the T-shaped incision.

STATE OF THE ART

US 2017/093069 A1 relates to an electrical contact with a plurality of electrical connection elements for contacting both a first conductive element and a second conductive element and with a holding member for holding the electrical connection elements. Each of the electrical connection elements includes a first contact portion for contact with the first conductive element, a second contact portion for contact with the second conductive element, and a holding portion held between the first contact portion and the second contact portion and with the holding member. For this purpose, holes with a small diameter are formed on the first conductive element in the bottom of a groove in such a way that they penetrate from the outer upper and lower surface to a receiving groove in the bottom of the groove. The small-diameter holes are provided at a position near both side surfaces of the first conductive member near the ends of the protruding flange portions of the groove. The small diameter holes have engaging pins inserted from the top and bottom outer surfaces.

CN 10 665 46 08 A describes an elastic electrical connector. The resilient electrical connector includes a base and a female clip, the base and the female clip being hinged to one another. The receiving terminal receives an electrical contact part, this having round free ends which are arranged in a hollow cylindrical recess and are closed on both sides by two cylindrical plugs with flange, the plug being pressed into the receiving terminal as a holding member.

The CN 20 825 69 68 U describes an elastic electrical connector, including a base, on the laterally opposite half-shells protrude upwards, into which the round webs of a connecting element can be used and these on all free ends of the half-shells by end flanges as Retaining member are covered.

DISCLOSURE OF THE INVENTION

Based on this prior art, the invention is based on the object of specifying an electrical connector in which the holding member holds the electrical connecting element or elements better and the connecting elements do not fall out.

Furthermore, it can be ensured with the present invention that a game for the electrical connecting elements can be adjusted.

An electrical contact has a first conductive element, an electrical connecting element, usually designed as a group of interconnected lamellae, for contacting the first conductive element and designed for contacting a feedable second conductive element and at least one holding member for holding the electrical Connection element on the first conductive element, wherein the first conductive element has at least one incision in the surface facing the feedable second conductive element, the electrical connection element at least a foremost and a rearmost positioning section, which are identical in a single lamella / contact section, for a Positioning in an associated retaining groove of the incision of the first conductive element and a contact portion for contact with the feedable second conductive element outside the incision. One to four holding members are then provided, one being sufficient for a blind hole design and two for a continuous groove design, each having a height greater than the height of the holding groove (s) of the incision assigned to it, with at least one holding member on or in one predetermined distance in front of the foremost positioning portion of the electrical connecting element is positioned in one of the holding grooves, and either that at least one holding member is positioned at or up to a predetermined distance behind the rearmost positioning portion of the electrical connecting element in one of the holding grooves or that one of the holding grooves has a blind hole a rear wall and that the rearmost positioning section of the electrical connection element is positioned at a predetermined distance in front of the rear wall of the blind hole groove in this blind hole groove.

The positioning mentioned here at a predetermined distance in front of or behind the foremost or rearmost positioning section is seen in the insertion direction or in the opposite insertion direction of the electrical connecting element into a continuous holding groove. The holding element can then be pressed into the holding groove in the direct insertion direction or counter-insertion direction, which means that a tool presses the holding element directly into the undercut and advances it to the intended position.

The positioning in the direction of insertion or in the opposite direction of insertion of the electrical connecting element can alternatively also be provided by pressing the retaining member into the retaining groove from the side of the insertion direction or opposite direction of insertion transversely in front of the contact section in the corresponding retaining groove. In this context, transversely means that the holding member is first pushed forward in the insertion direction (or opposite to this), for example in the middle of the T-recess above its bottom, and only at the predetermined depth (viewed in the direction of the groove) in front of the contact section transversely into the groove on the left or right is pressed. In this context, transverse does not necessarily mean at a 90 degree angle to the groove, but can also be an indentation in the forward direction, i.e. mean with an angle of, for example, between 30 and 60 and in particular 45 degrees.

In designs with an L-recess, so a only one-sided retaining groove, a further insertion direction can be provided, namely the lateral insertion of the positioning section or sections into the retaining groove and pressing the other opposite lateral elements of the electrical connecting element into the recess on its side wall.

The holding members can in particular be balls or cylinder sections. In the case of cylinder sections, one cylinder base can come to lie opposite the contact section, the other cylinder base can be broken off at the edge of the contact body so that the body can fill the groove up to the edge. But it can also be designed like a cube or a parallelepiped. What is essential is its excess over the groove and its greater hardness compared to the material of the first conductive element.

The electrical contact is in particular a flat contact with an incision and an undercut on one or both sides or a fork contact with two incisions opposite one another in the interior of the fork with such undercuts on one or both sides. In the case of a one-sided undercut, the incisions can be referred to as L-shaped incisions and in the case of a double-sided incision as T-shaped incisions, because the L-shape or T-shape only relates to the basic appearance of the incision with an undercut and not to the shape of the retaining groove itself.

The retaining grooves of the T-shaped incision do not have to be rectangular, they can also be round or triangular in cross section or correspond to a polygon, provided that the holding member pressed into these grooves has an excess that a pushing out or falling out of the holding member by the Use as such or pressure on the part of the contact section is impossible.

Advantageously, two holding members per T-shaped recess are sufficient here, and these two holding members can be positioned in a T-shaped recess in the same holding groove in the direction of introduction and the opposite direction of introduction.

Alternatively, these only two retaining members can also be positioned in the insertion direction in one retaining groove and in the opposite insertion direction in the other retaining groove.

In the case of an L-shaped recess, two retaining members are positioned in the insertion direction and the opposite insertion direction in this then single retaining groove.

The single incision with an undercut (in the case of an L-shaped incision) or one or both of the two incisions with an undercut (in the case of a T-shaped incision) do not need to have continuous holding grooves. The holding grooves can be blind grooves, that is, they can end in the solid material of the first conductive element. Then this end of the groove replaces the one holding member.At least only one holding member is then required, which is inserted on the opposite side (in the insertion direction) of the contact section, again, as stated above, this holding member with a T-shaped incision diametrically to the end wall of the holding groove can be used.

A method for producing such an electrical contact is characterized by the method steps of feeding the first contact section or sections of the electrical connection element or elements for contact with the first conductive element in the T-shaped incision at a predetermined distance from the side edges the electrical contact, the provision of two, three or four retaining members with a greater height than the height of the retaining groove of the T-shaped incision, the positioning of at least one retaining member on or at a predetermined distance in front of the first contact section in the direction of insertion of the electrical Connecting elements in one of the holding grooves and the positioning of at least one holding member at or up to a predetermined distance in front of the first contact section in the opposite insertion direction of the electrical connecting element or elements in one of the holding grooves.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

Fig. 1 shows a flat contact 10, which is a first conductive element. This has a cuboid shape in cross section with an underside 11 and an upper side 12, which are aligned parallel to one another. 2 shows an exploded perspective view of the flat contact 10 of FIG. 1 with the electrical connecting element 40 and holding members 50 shown laterally in front of it FIG. 4 with a cross-sectional view along the line IV-IV in FIG. 1.

In the top 12 of the flat contact 10, a retaining groove 20 is provided, which is designed as a T-groove. The retaining groove 20 extends laterally, i.e. in the width direction of the fork contact. Reference is briefly made here to FIG. 10, which shows a second electrical element 60 which is advanced in an insertion direction 65 for contacting and thereby at least in its end position covers the holding groove 20 and thus covers the electrical connection element 40. The holding groove 20 has a flat bottom 21 and, as the name T-recess suggests, has lateral holding grooves 22 and 23 which are designed as rectangular recesses in cross section in the insertion direction 65.

The rectangular recesses serve to receive side webs 42, 43 of the electrical connecting element 40. An electrical connecting element 40 is shown in FIG. Here, this electrical connection element 40 comprises five lamellae 41; any other number from 1 to X can also be provided, the number depending on the length of the holding groove 20 (and the holding members 50 to be explained below). X will rarely be over twenty, although there is no upper limit.

In other words, the retaining grooves 22 and 23 have flange portions protruding beyond the base 21 transversely to the insertion direction 65, also referred to here as: in an insertion direction 55, which is on the left side of the opening in FIG. 1 and on the rear side in 1 on the right of the receiving groove or holding groove 20 are formed.

In the first embodiment, the flange sections delimit the side webs of each of the electrical connecting elements 40 inserted in an insertion direction 55, so that the electrical connecting elements 40 cannot fall out of the holding grooves 22 and 23. The side webs have the general reference numeral 46, while the foremost side web has the reference numeral 42 and the rearmost side web has the reference numeral 43. These side webs can also be referred to as teeth, a pair of these teeth each carrying a lamella 41 of the connecting element 40 on the left and right.

This results in the problem known from the prior art that it must be prevented that the electrical connecting elements fall out of the retaining groove 20, wherein a movement in their insertion direction can alternatively be possible as a game or is completely prevented. This is prevented here by pressing holding members 50 into the groove or rectangular recess 23 on the right here in the insertion direction 55 and in a counter-insertion direction 56.

After the electrical connection element 40 has been positioned as shown in FIG. 1, a first holding member 50 is advanced into the groove 23 in the insertion direction 55 until it abuts the foremost side web 42 of the first electrical connection element 40 in the insertion direction. Simultaneously or thereafter, a second holding member 50 is advanced in the opposite direction, that is to say in the opposite direction of insertion 56 into the groove 23, likewise as far as the rearmost side web 43 of the electrical connecting element 40. Then the group of lamellas 41 of the electrical connection element 40 are fixed and can only move in a manner that results from the greater inclination of the electrical connection element 40 when the second electrical element 60 is inserted.

The holding members 50 of the present embodiment are full metal balls with a slightly larger diameter than the height of the groove 23. They hold by frictional connection. An essential property of the holding members 50 is their greater hardness than the material of the body of the flat contact 10.

Instead of advancing to the first / last web 42/43 of the electrical connecting element 40, the holding members 50 can also leave a predetermined distance from each other, which is derived from the known distance between the two webs 42/43 from each other and an additional predetermined clearance distance results.

In other exemplary embodiments, the two holding members 50 can alternatively both be pressed into the right groove 22 or they can push the electrical connection elements 40 diagonally, a metal ball 50 in the front right in the groove 23 and a metal ball 50 in the back left in the groove 22 or the other way around, hold. In any case, the use of two holding members 50 is sufficient.

Instead of metal balls, other shapes of the holding members 50 are also possible, with which a frictional connection can be achieved by overdimensioning the receiving grooves 22/23, such as rods, in particular cylindrical rods, which are pushed into the grooves 22/23. It is essential that these elements are completely embedded in the guide grooves 22/23 of the flat contact 10 and not protrude beyond the side wall of the respective groove 22/23 and does not protrude. This is then a longitudinally advanced in one of the or in both grooves 22/23 rod as a holding member. This replaces a ball in a groove.

Alternatively, in the case of a T-groove, a corresponding cross bar (not shown in the figure), which is oversized with respect to the receiving grooves 22/23, has been advanced in the two opposite grooves in the direction 55 or 56 on the groove bottom 21 to the predetermined space. Thus, for example compared to FIG. 2, the positioning of the first 42 or last 43 web would be overdetermined, since one ball 50 as a holding member in front of and one ball 50 behind the connecting element 40 is sufficient. In the case of a transversely inserted rod, the foremost 42 or rearmost 43 web is blocked in its two grooves 22 and 23. An advantage of the cross bar is that the excess can also affect the width of the recess, so that this cross bar is not only greater in height than the respective groove 22 and 23 but also in length can exceed the width of the overall recess. The cross bar can also first be inserted in a groove and pushed forward at an angle of e.g. 45 degrees, so that when the end position is reached in a groove around this point as a pivot point, it can then be moved into the transverse position and into the position in the other groove.

Finally, the “pressing in” of the holding members 50 can not only mean a direct longitudinal pressing into and through the groove 23 up to the position shown in FIG the arrow 59, which also defines an alternative “insertion direction” 59 here. Since the holding members 50 are oversized in their height over the groove 22 or 23, an indentation directly in the direction of arrow 55 or in the opposite direction 56 by the deformation of the groove 22 or 23 can be detected and is a physical feature, as is the positioning in the alternative insertion direction 59. Instead of the opposing insertion direction 56, there is then the alternative opposing insertion direction 58.

Fig. 5 shows a fork contact 110, which is the first conductive element. This has the shape of a C in cross section with a lower side 111, an upper side 112 and an upper inner surface 114 and a lower inner surface 113, which are aligned parallel to one another. 6 shows a perspective exploded view of the fork contact 110 of FIG. 5 with the electrical connecting element 40 and holding members 50 shown laterally in front of it and FIG. 8 with a cross-sectional view along the line VIII-VIII in FIG. 5.

All features that have received the same reference numerals in FIGS. 5 to 8 as in FIGS. 1 to 4 are executed in the same way and, unless specifically described here, reference is made to the above description of FIGS. 1 to 4 , in short: the same features have the same reference numerals.

In this upper inner surface 114 and in this lower inner surface 113 of the fork contact 110, a holding groove 20 is provided, which is designed as a T-groove. The two retaining grooves 20 lie opposite one another in the upper inner surface 114 and in the lower inner surface 113.

The two holding grooves 20 extend laterally in FIG. 5, i.e. in the width direction of the fork contact, while in the embodiment of FIGS. 15 and 16 extend in the longitudinal direction. The holding grooves 22 each have a flat bottom 21 and, as the name T-recess suggests, each have lateral holding grooves 22 and 23, which are designed as rectangular recesses in cross section in the insertion direction 65.

The rectangular recesses serve to receive side webs 46 of the electrical connecting elements 40. In other words, the retaining grooves 22 and 23 have flange portions protruding beyond the base 21 transversely to the insertion direction 65, which are on the left and on the opening side in FIG on the rear side in FIG. 5 on the right of the receiving groove or holding groove 20 are formed.

In the second embodiment, the flange sections delimit the two side webs 42 of each of the inserted two electrical connecting elements 40, so that the electrical connecting elements 40 cannot fall out of the holding grooves 22 and 23. Or in other words, the electrical connection elements 40 are to be pushed in from the side which runs transversely to the direction 65 from FIG. 9, that is to say in the insertion direction 55. The side webs 46 are connected to a continuous central web 44 as a retaining strap, so that the side webs can be viewed as teeth extending to the left of the central web in a comb-like manner. The lamellae of the electrical connecting element 40 are mechanically connected to the retaining strap as described in connection with FIG. 11. In other exemplary embodiments not shown here, the fastening of the slats 41 can be implemented differently; What is essential is the existence of at least one-sided (see embodiment, Fig. 12) teeth or side bars as positioning sections for the retaining grooves, left and right, left or right, or one-sided.

As in the first embodiment, the connecting elements 40 are fixed in their position in the respective T-recess 20 by pressing holding members 50 into the right here groove or rectangular recess 23 above and below and prevented from falling out. Therefore, the four holding members 50 are arranged here in FIG. 6 to the right of the two connecting elements 40 arranged upside down. They are all inserted in the insertion direction 55 or in the opposite insertion direction 56, the alternative insertion direction 59 also being possible.

After the electrical connection elements 40 have been positioned as shown in FIG. 5, a first holding member 50 is advanced in the insertion direction 55 into the (for example) lower groove 23 until it abuts the foremost side web 42 of the first electrical connection element 40 in the insertion direction. At the same time or thereafter, a second holding member 50 is advanced in the opposite direction 56 into the lower groove 23, likewise as far as the rearmost side web 43 of the electrical connecting element 40. At the same time or thereafter, the holding members 50 for the other connecting element 40 are pushed into the upper groove 23. The electrical connecting elements 40 are then fixed and can only move in a manner as is evident from the greater inclination of the electrical connecting elements 40 when the second electrical element 60 is inserted, which is shown in FIG.

Here too, instead of being pushed forward to the first / last web 42/43 of the electrical connecting element 40, the holding members 50 can also be set at a predetermined distance from one another, which is derived from the previously known distance between the foremost and rearmost webs 42 and 43 results as positioning sections from each other and an additional predetermined clearance distance. This can be handled in the same way for the upper and lower connecting element 40, that is to say no play or play in both.

In other exemplary embodiments, the two holding members 50 per connecting element 40 (top and bottom) can alternatively both be pressed into the right groove 22 or the electrical connecting elements 40 can be pressed diagonally, a metal ball 50 at the front right in groove 23 and a Metal ball 50 at the rear left in groove 22 or the other way around. In any case, the use of two holding members 50 per connecting element 40 is sufficient.

Instead of metal balls, other shapes of the holding members 50 are also possible here, with which a frictional connection can be achieved by overdimensioning with respect to the receiving grooves 22/23. In the area of the height and the movement of the holding members 50 in this direction, there is a form fit with oversize, essential for the function is the frictional connection made possible by this oversize in the form fit in the insertion direction 55 or in the opposite insertion direction 56, which reduces the movement of the connecting elements 40 to a game or completely limited.

9 shows a side view of FIG. 5 with an additionally inserted second conductive element 60 and FIG. 10 shows a side view of FIG. 1 with an additional inserted second conductive element 60. The function of the front inclined edges 25 or 125 and 126 of the flat contact 10 or the fork contact 110 clear, namely that the second conductive element 60, which then closes the contact, more easily on the upper side 12 or between the lower and upper inner side 113 and 114 in the insertion direction can be advanced. It also becomes apparent that the connecting elements 40 are bent in the transverse direction when they are pivoted by the second conductive element 60 when it runs onto the run-up edge 45 of the connecting elements 40 about the axis specified by the side webs 46 of the retaining strap 44. No or hardly any additional forces are exerted on the holding members 50 by the side webs 42, but rather the side webs 42 tilt at most in the grooves 22 and 23. It is clear that in the embodiment according to FIG the contact elements 41 can be brought in, with an inclined edge 45 advantageously being available as a run-up edge.

To explain a possible group of here five lamellae of a connecting element 40, FIG. 11 shows an enlarged view of the electrical connecting element 40 used in the embodiments of FIGS. 1, 5 and 15 compared to the other figures Edge 45 inclined towards the insertion direction, it being evident from FIG. 6 that the pivoting movement about the axis given by the side webs 46 during fork contact takes place in mutually opposite directions. The lamellae 41 of the connecting elements 40 are preferably already inclined in one direction in the insertion direction, so that further pivoting is carried out when the second conductive element 60 is advanced.

The body of the flat contact 10 or the fork contact 110 is made of conductive metal. The holding members 50 can also be made of metal. You must have an excess over the height of the corresponding groove 22, 23 at least at the positioning point and are plastically deformed when pressed. The deformation can also be detected on the surfaces of the groove 22, 23 when they are pressed directly into the undercut.

12 shows a further flat contact 310, which is a first conductive element. This has a cuboid shape in cross section with an underside 11 and an upper side 12, which are aligned parallel to one another. 13 shows a perspective exploded view of the flat contact 310 of FIG. 12 with the electrical connection element 40 and holding members 50 shown laterally in front of it. 12th

The difference between the flat contact 10 of FIG. 1 and the flat contact 310 of FIG. 12 is that the retaining groove 320 is an L-shaped recess, that is, a one-sided groove 22 with a side wall lying opposite the longitudinal direction of the groove 22 . In other embodiments, it can of course be a groove arranged on the right in the drawing compared to FIG. 12 and a side wall then arranged on the left, although the embodiment shown in the drawing is preferred when the second conductive element 60 is introduced via the inclined ramp surface 25.

Here, the retaining strap 44 of the connecting element 40 is provided with teeth or side bars 46 on only one side in a comb-like manner, the foremost left side bar 42 and the rearmost side bar 43 in turn being blocked by the holding members 50. Here both holding members 50 must be introduced into the single groove.

In addition to the insertion directions 55 and 56, there is also the possibility of a further insertion direction, which is indicated by the reference number 57, comprising a lateral insertion of the side webs 46 into the groove 22 and a subsequent pressing from above of the connecting element 40 onto the floor 21 of the retaining groove 320.

15 shows a further flat contact 410, which is a first conductive element. This has a cuboid shape in cross section with an underside 11 and an upper side 12, which are aligned parallel to one another. The holding groove 420 is aligned in the longitudinal direction. The longitudinal direction here means that the insertion direction of the second conductive element 60, as shown in FIGS. 9 and 10, is aligned in the longitudinal direction of the holding groove 420. 16 shows, for explanation, a perspective exploded view of the flat contact 410 of FIG. 15 with the electrical connecting element 40 and holding members 50 shown laterally in front of it.

The embodiment of Figs. 15 and 16 show a blind hole groove with a left blind hole groove 222 and a right blind hole groove 223. These end in the solid material of the flat contact body at a groove rear wall 222 'and 223', respectively. So that a stop is given for the rearmost pair of side webs 43, which replaces the holding member. It is then sufficient, as shown in the exemplary embodiment, to position a holding member 50 in front of one of the foremost side webs 42, left or right. Here the ball is shown as a holding member 50 on the left.

It is also possible that the blind hole grooves 222 and 223 actually end at a rear wall 222 'and 223' and thus the T-recess ends, but that the holding groove 420 with the flat bottom is continued to the opposite side wall of the flat contact 410 . The positioning takes place analogously to the above illustration in FIG. 16.

It is clear that in embodiments of the invention, all sixteen possibilities of the arrangement of the four following features should be covered. Transverse direction or longitudinal direction of the groove (Figs. 1, 5, 12 compared to Fig. 15) Continuous groove or blind hole groove (Fig. 1, 5, 12 compared to Fig. 15) T-groove compared to L-groove (Fig. 1, 5, 15 compared to Fig. 12) Flat contact or fork contact (Fig. 1, 12 and 15 compared to Fig. 5) with the above-explained freedom of the arrangement of the holding members 50 left and / or right, with play and without, as a ball, longitudinal rod or cross rod, advantageously not protruding beyond the outer side walls of the contacts and wherein a holding member can also be formed by its rear wall 222 ', 223' in the case of a blind hole provided at least on one side.
