Electrical plug connection element and plug connection part with a plurality of plug connection elements

The invention relates to an electrical plug connection element and a plug connection part with a plurality of such plug connection elements.

Usually, a plug element and a socket element is plugged together in electrical connectors, wherein the contact elements of the plug element and the socket element come into electrical contact with each other and is guided over the contact surfaces thus produced the electric current. Known connectors provide slotted contacts in which two contact surfaces between pin and socket are formed by a slot. Also known is the embodiment with two slots, are formed by the four contact surfaces. A higher number of contact surfaces results from the use of so-called lamellar contacts. In this case, for example, punched fins are mounted in a contact carrier. Due to the large number of contact surfaces results in a high contact reliability.

From DE 10 2007 042 1 94 A1 discloses a connector element with a contact member is known which has at least one line contact, by means of which the contact member when mating with a associated connecting element is electrically connected. The achievable contact and current carrying properties are already very good.

The invention is based on the object, a plug connection element and a plug connection part with a plurality of such

To provide connector elements, which have compared to the known connector elements or connector parts even further improved performance characteristics. In one embodiment, a high contact reliability and high current carrying capacity is to be ensured with simple plug-in, in particular, should

Plug connection element and the connector part insensitive to mechanical and / or thermal stress.

This object is achieved by that defined in claim 1

Plug connection element and the connector part defined in the independent claim solved. Particular embodiments of the invention are defined in the subclaims.

In one embodiment, the connector element has at least two formed by shaped electrically conductive sheet metal strips

Contact plates on, each having a connection section for the

electrical connection of the connector element to a

have to be connected electrical line and a

Contact section for a detachable electrical connection of the

Plug connection element with an associated connection element and arranged between the connection portion and the contact portion compensating portion for an elastic deflection of the contact portion relative to the connection portion, wherein the Connecting portion, the compensation portion and the contact portion are each formed integrally with the metal strips.

The provided by the compensating portion elastic deflection is advantageous in the assembled state of the two connector parts, as this discrepancies in the position of the pins are mounted in the assembled connector system and not to a

decreased contact and thus to a reduced

Current carrying capacity. Occurring vibrations can be absorbed by the strain relief described below. Due to the provided insertion bevels and / or contact surfaces and / or the over-spring the forces required for insertion and removal are adjustable.

In one embodiment, the three sections are arranged one behind the other in a longitudinal direction of the plug connection element and can provide the respectively assigned function without negatively influencing each other. All three sections are integrally formed by one or more contact plates, so that contact points are avoided, for example between the terminal portion and the contact portion.

The contact plates form the contact element of the connector element. Due to the compensating section, the contact sheets, despite a comparatively large cross-sectional area, which has a high

Current carrying capacity provides sufficient flexibility. Therefore, the contact sheets can be directly, i. without interposition of a

contact organ, are brought into contact with the contact member of the associated connector part. It thus eliminates an additional contact point required in the prior art with high current carrying capacity at the junction of the contact member to a further portion within the connector element. The invention

Plug connector therefore not only has a high

Current carrying capacity, but also has an improved

Vibration resistance.

The material for the contact sheets is preferably pure copper to minimize the total resistance of the connector element.

The material used is preferably oxygen-poor or oxygen-free copper. This makes it possible, even at higher temperatures, such as when using according to the invention

Plug connection elements in automotive technology, especially in hydrogen-powered vehicles, can set, prevent embrittlement of the contact plates. The contact portion or preferably the entire contact sheet may have a surface coating, for example made of silver or other precious metal, around the

To reduce contact resistance even at high mating cycles.

In one embodiment, the contact plates in the connection section are enclosed by an at least partially sleeve-shaped connecting element, by means of which the contact plates are fixed in their position relative to one another in an initial state. For this purpose, the contact sheets can be bent partially circularly in the connection section, in particular approximately semicircularly, when two contact sheets are used, so that the insertion of the connection section of the two

Contact plates in the connecting element results in a fixation of the contact plates. When connecting the electrical line is using the

Connecting element made a crimped connection of the contact plates with the electrical line. By using a sleeve, a permanent and aging-resistant contact is guaranteed. At its end facing the electrical line to be connected, the connecting element preferably has an insertion bevel. The connecting element preferably also consists of comparatively soft copper. Preferably, hexagonal crimping is done to improve the contact properties and provide a permanently secure mechanical connection between the

To provide connector and the electrical line.

In one embodiment, the sleeve extends beyond the crimp area. As a result, the deformation of the contact sheets in

Connection section not on the adjoining compensation section. In order to further improve this mechanical shielding effect, the connecting element in one embodiment has a support element, for example a one-stage or multistage, in particular

two-stage, annular flange, with which the connecting element is alternatively or additionally supported on a housing of the associated connector part. As a result, movements and / or vibrations of the connected line, which may, for example, be a cable, are absorbed by the associated connecting element and are not transmitted to the contact section.

In one embodiment, at least one of the contact plates in the compensating section has a reduced flexural rigidity. This can for example by one or more recesses in the wall thickness and / or provided by one or more lateral cuts in the stripe width of the contact sheets. As a result, a desired articulation point is created, which allows a deflection of the contact portion relative to the connection portion with a comparatively small force. As a result, in a particularly advantageous manner are low

Insertion forces realized and / or especially a compensation

Temperature-induced expansion states of the cooperating components, which consist of different materials. Because that

Contact plate is fixed in the crimp, can be provided by the compensation area and an elasticity of the connector element, which ensures despite production-related tolerances optimal contact in the contact section.

In one embodiment, at least one contact plate, preferably all, and in particular both contact plates, of the plug connection element are bent meandering in the compensating section or in any case are bent.

As a result, in the contact section, the contact sheets with

relatively little effort be deflected such that mating of the connector element with an associated connection element and the release of such a connector with little effort are possible. In meandering

Compensation section, the two sections in parallel

extending leg a distance from each other. This ensures a movement play when deflecting. At the bending points of the compensation section, the rigidity of the contact plate may be reduced, for example by a material recess, and in particular by a local reduction of the width of the contact plate. In one embodiment, at least one contact plate in

Compensation section a preferably integrally formed

Stop means to limit the deflection of the contact portion relative to the terminal portion. For example, at least one of the legs running in the meandering region of the

Contact sheet a lateral extension towards the

be bent opposite leg. At a maximum deflection of the bent portion comes into contact with the

opposite leg, whereby the deflection is limited.

In one embodiment, at least one contact plate in

Contact portion of a cross-sectional shape, which differs from the cross-sectional shape of a contact member of the associated connecting element; this is when mating with the associated

Connecting element formed two electrical line contacts. In one embodiment, at least one contact plate of the contact portion is bent in a V-shape or U-shape. When mating the

Plug connection element with the associated connection element are formed by each contact sheet two electrical line contacts. In one embodiment, in which the connector element has two contact plates, thereby a total of four electrical

Line contacts formed. The length of the line contacts is limited by the length of the V-shaped or U-shaped contact plates in the

Contact section. In one embodiment, this length is between 2 and 20 mm, in particular between 4 and 15 mm and preferably between 6 and 10 mm. This allows, for example, a

Provide short-circuit current capability of 3,000 A for 1 s. In one embodiment, the contact plates in the contact section form a plug-in receptacle for a pin-shaped contact element of the associated connecting element, for example. The longitudinal axis of the plug-in receptacle and thus the plug-in direction can be longitudinal or oblique and

in particular transversely to the longitudinal direction of the plug connection element, in which the contact portion, the compensation portion and the

Connection portion are arranged one behind the other, be aligned.

In one embodiment, a foreign spring is in the contact portion

arranged, with which the contact plates are durable in contact-bearing contact with the associated connecting element. The foreign spring may be made of a spring steel with suitable elastic materials, in particular, are no special electrical properties

required. Preferably, the foreign spring is not one

made magnetizable material. The foreign spring is outside the current path, so that an electrical contact only between the

Contact section of the contact sheet and the contact element of

assigned connecting element takes place. In one embodiment, the foreign spring has an annular portion which limits the maximum expansion of the contact plates in the contact portion. From the annular portion spring arms can protrude, in particular in the direction of the associated connecting element facing the end of the contact plate, which apply the required contact force. The spring arms can be bent radially inward to be held in contact with the contact plates. The number of spring arms can match the number of contact plates or a multiple of the number of contact plates. In one embodiment, the foreign spring on guide means, by means of which the foreign spring in an extending in the insertion direction

Recess between the contact plates guided on the contact plates can be plugged. The guide means can also protrude in the insertion direction of the annular portion of the foreign spring and be bent radially inward.

In one embodiment, a contact plate preferably on

Transition from the contact portion to the compensation section arranged stop means for the foreign spring. The slings can

in particular be arranged at the transition from the V-shaped or U-shaped contact portion to the meander of the compensation section. By the stop means a depth stop when pushing the foreign spring is provided.

The invention also relates to a plug connection part with a plurality of plug connection elements according to the invention as above

described, wherein the connector elements are arranged as equal parts in a common housing of the connector part.

As a result, multi-pin plug connection parts in the manner of a modular system can be equipped with connector elements according to the invention. The individual connector elements of a

Plug connection part can be constructed completely identical and also have identical dimensions. Alternatively, the connector part also dimensioned differently

Record connector elements, for example for different high load currents. The connector element according to the invention can be scaled for different rated currents. For example, for a

Rated current of 100 A, the contact plate at a width of 8 mm have a thickness of 0.8 mm, and in the connection section can

Cables or cables with a cross-sectional area of 16 to 25 mm ^{2 can be} connected. At a nominal current of 200 A, this can be

Contact sheet with a width of 12 mm a thickness of 1, 0 mm

and in the connection section cables or cables with a cross-sectional area of 35 to 50 mm ^{2 can be} connected.

With a nominal current of 400 A, the contact plate can have a thickness of 1, 25 mm with a width of 1 6 mm, and cables or cables with a cross-sectional area of 70 to 95 mm ^{2 can be} connected in the connection section. In one embodiment, the connector elements are designed for electrical voltages in the range of more than 12 V and less than 2400 V, in particular more than 24 V and less than 1000 V and preferably up to an operating voltage of 700 V. In one

The first connector part 202 has a bow-shaped

Actuator 242, with which the two connector parts 202, 204 from the fully assembled in Figs. 3 and 4 state in a state shown in FIG. 5 can be transferred, in which the pilot contact 218 is either already separated, or at least one complete transfer of the actuating element 242 is separated in a relation to the illustration in Figs. 3 and 4 rotated by 90 ° position, the load contacts 212, 214 but are still electrically connected. The actuator 242 is about a preferably integrally formed by the first connector part 202 axle journal 244th

pivotable, whereupon a in the actuator 242, for example, introduced by a groove cam 246 is moved along a arranged on the second connector part 204 guide pin 250 that the first connector part 202 lifts from the second connector part 204.

When the actuating element 242 assumes a position rotated by 90 ° relative to the position in FIG. 3, the pilot contact 218 of the first plug connection element 202 is no longer in electrical Connection with the pilot contact of the second connector element 204, whereas the load contacts 212, 214 of the first

Plug connection element 202 are still in electrical connection with the load contacts of the second plug connection element 204.

The actuator 242 may in its in Figs. 3 and 4

shown first end position and / or in a contrast rotated by 90 ° second end position releasably be locked. By the leverage of the actuator 242 is both the opening and the

Closing the connection between the first and the second

Plug connection part 202, 204 only a small operating force

required. This is particularly advantageous at high temperatures and / or soiling environmental conditions. The first plug connection part 202 and the second plug connection part 204 have mutually corresponding latching means 252, 254, wherein in the exemplary embodiment, the latching means 252 of the first connector part 202 is formed by a recess in a housing wall, in which engages the associated latching means 254 of the second plug connection part 204 when plugging while locked with the opening. For this purpose, the locking means 254 of the second connector part 204 has a run-on slope, by means of which the locking means 254 is deflected during mating and snaps back as soon as the locking means 254 engages in the opening in the first connector part 202.

After transferring the first connector part 202 from the position shown in FIGS. 3 and 4 in the position shown in FIG. 5 or beyond in a position in which the

Actuator 242 has been pivoted by 90 °, the locking means 254th of the second connector part 204 in abutment with the edge of the latching means 252 forming opening of the first connector part 202. As a result, a complete removal of the first connector part 202 is prevented. Only after, for example by means of a

Screwdriver or other suitable tool, which is for example introduced into the opening and then rotatable, the locking means 254 is brought out of engagement with the locking means 252, the first connector part 202 can be completely removed. The fact that first the actuator 242 must be actuated, and thereby the pilot contact 218 is disconnected while the load contacts 212, 214 are still in communication, and then the locking means 252, 254, for example by means of a tool, alternatively also without tools by hand, disengaged must be brought before the first

Plug connector 202 can be completely removed, resulting in practice a time delay of, for example, at least 0.5 or 1 second. This allows a higher-level controller the

Load contacts 212, 214 to de-energize after it is signaled by the separation of the pilot contact 218 that the connection should be disconnected.

Even when plugged together, there is the possibility that initially by attaching the first connector part 202 a

Connection of the load contacts 212, 214 is made, and only by the subsequent pivoting of the actuating element 242 and the

Pilot contact 218 is closed, whereupon a parent

Control line can put the load lines under power. Thus, both the plugging and the release of the electrical connection of the

Load contacts 212, 214 take place without current, whereby the electrical contacts be spared and a permanently reliable electrical connection can be provided.

6 shows a perspective view of an enlarged detail in the region of the latching means 252, 254 in a state in which the first

Plug connector 202 are completely mated with the second connector part 204 and both the load contacts 212, 214 and the pilot contact 218 are closed. FIG. 7 shows an enlarged detail in the region of the latching elements 252, 254 in a state in which the first plug connection part 202 is so far from the second

Plug connector 204 is solved that the pilot contact 218 is disconnected, the load contacts 212, 214 but still connected.

The latching element 252 of the first connector part has a first opening portion 256 which is slightly larger than a first portion 258 of the second latching element 254, but smaller than a second portion 260 of the second latching element 254. This results in the position shown in FIG the second section 260 in abutment with the housing 48 of the first connector part 2 and blocks a complete removal of the first connector part 202 from the second connector part 204. Only by a deflection of the second locking element 254,

For example, by means of a tool, the second portion 260 is brought into coincidence with a second, opposite the first opening portion second opening portion 262 of the first locking element 254, which is slightly larger than the second portion 260 of the second locking element 254, so that the first connector part 202th can be removed from the second connector part 204. 8 shows a section of a section through the housing 48 of the first connector part 2 in a region in which the electrical line 6 shown in a view with the first

Plug connection part 2 is connected. The cable 6 is a cable with an inner conductor 53, which is surrounded by an insulation 55, on the outside of a metallic conductive cable shield 57 is applied. At its end concealed by a sleeve-shaped connecting element 78, the inner conductor 53 is electrically and mechanically connected to an electrical plug connection element 10 (FIGS. 7, 18), which is described below.

The connector part 2, which is a device 1 1 for electrically connecting the cable shield 57 of the electric wire 6 with the

Housing 48, further has a three-piece fixing in the illustrated embodiment 81, 85, 87, by means of which the

Connecting element 78 and thus the inner conductor 53 in the occurrence of a tensile force on the line 6 by positive engagement immovable in the

Housing 48 is fixed. The connecting element 78 is at least partially sleeve-shaped and mechanically fixedly connected by clamping with the inner conductor 53, in particular with the inner conductor 53 pressed. The pressing takes place with the interposition of two contact plates 72, 74, which also form the contact member of the connector element 10 in one piece. The connecting element 78 has at least one end on a flange-like widening 84, which forms a form of a positive connection in the direction of the tensile force and preferably annular contact surface 79 for a first part 81 of the fixing. The first part 81 of the fixing element is sleeve-shaped and surrounds the Connecting element 78 and extends in the direction of an end facing away from the contact element of the connector element 10 beyond the connecting element 78 addition. At its front end, the first part 81 of the fixing element with the interposition of a radially outwardly extending connecting line 83 for the cable shield 57 in contact with a second part 85 of the fixing, which is also sleeve-shaped and the line 6 receives in itself. At its end opposite the first part 81, the second part 85 has a contact surface for a third part 87 of the fixing element, which forms a positive connection with the housing 48 in the direction of the tensile force.

The third part 87 of the fixing element is in the embodiment

formed clamp-shaped, wherein the associated bracket in a designated opening 89 (Fig. 1) in the housing 48 in a direction obliquely and in particular transversely to the insertion direction or to the longitudinal direction of the line 6 can be inserted and thereby locks the fixing in the housing 48. When a tensile force on the cable 6 occurs, this tensile force is transmitted to the connecting element 78 via the inner conductor 53

transferred, which in positive engagement with the first part 81 of the fixing, this in turn in positive engagement with the second part 85, and this in turn in positive engagement with the third part 87, wherein the third part 87 in positive engagement with the housing 48th is. As a result, a firm connection between the conduit 6 and the housing 48 is provided, which is based only on positive engagement and is independent of frictional forces.

The device 1 1 is part of each pole associated

Receiving chamber for each load contact 12, 14, 16, 212, 214 in each embodiment of the housing 48 of the first connector part second The device 1 1 may be formed the same for both straight connector and angled connectors except for the formation of the contact members. The device 1 1 also has an intermediate element 91, which may be made of a plastic. The intermediate element 91 can also be referred to as insulating sleeve. The intermediate element 91 comprises the connecting element 78 at least in sections and projects in the direction of the contact element of the plug connection element 10 via the

Connecting element 78 addition. In the illustrated embodiment, the intermediate element 91 integrally forms a sleeve-shaped

Guide portion 75 which comes when mating the first and second connector part 2, 4 in abutment against the sleeve-shaped portion 32 (Fig. 1) of the second connector part 4 and is guided.

The device 1 1 has a spring element 93, with which the

Connecting element 78 is biased in the housing 48 in the direction of the positive engagement with the fixing element, in the exemplary embodiment, it is biased in the direction of the first part 81 of the fixing.

In the embodiment of FIG. 14, a shielding element 1 59 is used, as shown in Figures 10 to 13. The

Shield element 1 59 comprises a third part 137 with which the cable shield 1 57 of the line 106 is mechanically fixed, in particular crimped; the third part 1 37 can also be called Stützcrimp. The third part 1 37 encloses both the cable shield 1 57 on the insulation 155 and the outer cable sheath of the line 106 fixed. The portion of the third part 1 37, which encloses the insulation 155 and the cable shield 1 57, is axially spaced from the portion of the third part 137 which surrounds the outer cable sheath. The embodiment of the housing 148 of FIG. 14 is like the embodiment of FIG. 8 inside conical. in the

In contrast to FIG. 8, in the housing 148 of FIG. 14, the external shape is also cone-shaped, since the wall thickness is approximately constant.

About the portion which encloses the insulation 1 55 and the cable shield 157, the protruding and shortened to a suitable length end of the cable shield 1 57 is folded over and is enclosed by the second part 135 of the shield member 1 59. The second part 1 35 is shaped such that its outer edge reaches almost to the inner surface of the housing 148. To stiffen the front end of the second part 135, this has a stiffening means 139, which is formed in the embodiment by an annular recess. On the outside, the second part 135 has a preferably circumferential and perpendicular to the longitudinal axis extending edge portion 141 which is set back in the embodiment of the axial ends of the second part 1 35, wherein the distance to the one axial end is smaller than to the opposite other axial The End. On the outer edge, the second part 185 of the fixing element is supported positively in the axial direction; the second part 185 may also be referred to as a sealing sleeve. At the front end of the second part 1 35 of the shield member 1 59, the first part 181 of the

Fixing element in the axial direction from a form-fitting, wherein the support of the first part 181 is radially inward relative to the support of the second part 185 of the fixing element; the first part 181 may also be referred to as a spacer sleeve. In the exemplary embodiment, the second part 135 is rotationally symmetrical to its longitudinal axis. By turning the cable shield 1 57 this has a defined distance from the main contact.

Between the edge portion 141 of the second part 135 and the housing 148, the first part 1 31 of the shield member 159 is arranged. In the exemplary embodiment, it consists of a slotted sleeve which, in the undeformed state, has a shape deviating from the cylindrical shape,

in particular conical.

In the installed state shown in Fig. 14, the first part 1 31 is approximately brought into a cylindrical shape, since during assembly, the cable of the line 106 with the parts mounted thereon in the housing 148 is inserted. By the restoring force of the first part 1 31 this is in safe electrical contact on the one hand on the inner surface of the housing 148 and on the other hand on the second part 1 35 of the

Shield element 1 59. At the end of the first part 131 preferably integrally formed stop means for abutment with the second part 135 are arranged, in particular for engagement with the edge portion 141 of the second part 1 35, which ensures that the first part 131 axially in one defined position in the housing 148, in particular in a defined position relative to the second part 1 35 and thus with respect to the line 106. The stop means may be formed by the second contact tongues 143.

Due to the arrangement of three contact tongues 161 and three second contact tongues 143, a defined contact of the first part 131 is ensured both radially outward on the housing 148 and radially inward.

The outer diameter of the second part 135 in the region of

Edge portion 141 is only slightly smaller than the clear width of the housing 148 minus the thickness of the first part 131, so that in this area a game of less than 2 mm, in particular less than 1, 2 mm and preferably less than 0.8 mm results; in the

Embodiment, the distance is about 0.5 mm. At a Radial movement of the line 106, in particular of the cable with the parts mounted on it, ie also with the second part 1 35, the first part 1 31 moves to that axial position at which the first part 1 31 electrically contacts the second part 1 35 , also, wherein the movement by the abutment of the first part 131 on the inside of the housing 148 undergoes a stop.

At its opposite end, however, the first part 1 31 experiences no movement in the radial direction, because the first part 1 31 is centered within the housing 148 by the contact tongues 161.

This results in a pivoting movement of the first part 131, which has the advantage that thereby takes place a relative movement at the contact points, thereby cleaning the contact surfaces. The end portion of the first part 131, with which the first part 131 is in communication with the second part 135, is at an angle of more than 0.2 ° and less than 6 °, in particular more than 0.5 °, with respect to the adjacent part and less than 4 ° and preferably more than 0.5 ° and less than 2.5 ° inwardly bent so that this end portion at a

Pivoting movement of the first part 1 31 undergoes no bending stress, which would be detrimental to the occurrence of vibration. The length of the bent portion is less than 30% of the length of the first part 1 31, in particular less than 20% and preferably less than 15%. In the exemplary embodiment, the length of the bent portion is up to +/- 25% equal to the length of the second contact tongues 143.
