Description

Technical area

[0001] The present invention relates to a connector with a power-amplifying plug and a corresponding header. State of the art

[0002] The present invention is described below mainly in connection with high-voltage electrical systems for electric vehicles.

[0003] A connector for the electrically conductive connection of a high-voltage cable can require high mating forces to connect the contact elements of the connector partners. At least one contact element can be elastically deformed during mating to generate a contact force between the contact elements through a restoring force that counteracts the deformation.

[0004] To generate the mating forces, at least one of the mating partners can have a locking lever with at least one force reduction curve. A locking pin of the other mating partner can slide over the force reduction curve when the locking lever is actuated, pulling the mating partners together via a wedge effect of the force reduction curve.

[0005] Two locking pins can be arranged on opposite sides of the connector to apply the proportional mating forces symmetrically to the mating partners. A driving force can then be applied to a common locking lever with two force reduction curves or to two separate locking levers, each with a force reduction curve.

[0006] As the force reduction curve slides over the locking pin, the entire proportional mating force is transmitted via a small contact area between the locking pin and the force reduction curve. This places significant stress on the locking pin and the force reduction curve. Since the radius of the force reduction curve is constantly changing, the contact area cannot simply be increased. Due to the rotation of the locking lever, a driving force on the locking lever can only act proportionally in one mating direction of the connector.

[0007] The locking lever requires space next to the connector because the locking lever protrudes from the connector, at least in an open position.

[0008] Document DE 10 2017 213 446 A1 discloses a connector 100 comprising a first connector 1 and a second connector 2. The first connector 1 and the second connector 2 are engaged by relative displacement in axial directions. The axial directions include an axial direction of an outer housing 3 and an inner housing 4 of the first connector 1 and an axial direction of the second connector 2.

[0010] Document US 2002 / 0 019 160 A1 discloses a connector C1 and a mating connector C2. The mating connector C2 comprises a large number of terminals 40 extending longitudinally and a housing 41 that accommodates the terminals 40.

[0011] Document EP 0 889 555 A2 discloses a connector assembly comprising a first connector 1, a holder 2 holding the first connector 1, and a second connector 3 to be coupled to the first connector 1. A pivot lever 4, which rotates in a coupling direction of the second connector 3 to the first connector 1 upon connection of the connectors 1 and 3, is pivotally mounted between the first connector 1 and the holder 2 by means of a bearing pin 5.

[0012] US Pat. No. 6,315,585 B1 discloses an electrical connector with a lever. The electrical connector has first and second connector housings 10, 20, which are adapted to be releasably joined by relative movement in an assembly direction. A lever is rotatably mounted for pulling the connector housings.

[0013] The document DE 10 2013 216 829 A1 discloses an arrangement 1 for a plug 9 which can be plugged together with a mating plug 11. The arrangement 1 comprises a housing part 5, with an actuating element 3 which can be displaced linearly along the housing part 5 in an actuating direction (B), with a central chamber 4 surrounded on the outside by the housing part 5 and the actuating element 3, and with at least one reversing gear 7a, 7b, 8a, 8b, the drive 12 of which is connected to the actuating element 3 and the output 14 of which is designed to be engageable with parts of the mating plug 11. Description of the invention

[0014] One object of the invention is therefore to provide an improved connector with a force-enhancing connector and a corresponding header. An improvement may, for example, relate to a reduced space requirement next to the connector, a reduced force required to establish the connector, and improved handling.

[0015] The problem is solved by the subject matter of the independent claim. Advantageous developments of the invention are specified in the dependent claims, the description, and the accompanying figures.

[0016] A plug connection is established between a connector and a header. The header can be located, for example, on a component of the high-voltage electrical system. The connector can be located, in particular, at one end of a high-voltage cable in the high-voltage electrical system. The header can also be located at another cable end.

[0017] In the approach presented here, the applied drive force acts in one direction of the plug connection throughout the entire plugging process. A drive movement is converted into an output force by a gear-like system on the plug. The drive force is thus added to the output force amplified by the system. The system consists of at least one rotatably mounted lever with a geometrically defined lever ratio between a drive side and an output side. The drive side slides in a slotted guide of a slide. The slide is moved linearly in the plugging direction by the drive force. In the slotted guide, the linear drive movement is converted into a rotary movement of the lever. Only the unamplified drive force is transmitted to the lever via the slotted guide. The drive force and a counterforce to the amplified output force are transmitted to a plug housing of the plug via an abutment on the lever.The increased downforce is supported by a positive connection to a counterpart on the header.

[0018] The approach presented here allows the connector to be actuated in the mating direction. This prevents the connector from tipping sideways when mating with the header. By adding the actuating force to the amplified actuating force, a lower amplification of the actuating force and a lower actuating force are required overall. Actuating in the mating direction requires less space next to the connector, and multiple connectors can be arranged closely spaced.

[0019] A plug connection with a plug with force amplification and a header corresponding to the plug according to claim 1 is proposed.

[0020] The connector is a component of the connector. The connector is mated with the corresponding header. The connector and header can have essentially identical mating geometries, which determine the mating direction of the connector via guide surfaces that run essentially parallel to each other.

[0021] A connector housing can house the connector's electrical components and the plug geometry. The connector housing can be centrally located in the connector. A slider can be a handle of the connector. The connector housing can be located within the slider. A lever can be located in a space between the slider and the connector housing. The slider and the at least one lever form a mechanism of the connector. The connector housing, the slider, and the lever can be made of a plastic material.

[0022] A link can be an elongated recess or depression. A drive pin of the lever can be movably arranged in the link. The drive pin can rotate in the link and slide along the link. The drive pin can also be rotatably mounted in a sliding piece. The sliding piece can be movably mounted in the link. The drive pin can move along the link when the link is moved relative to the lever. The link can specify a path of movement for the drive pin. The link can be straight. The link can also be curved. The link can be wider than the drive pin. For example, the pin can rest on one side of the link and slide along one side when moved. In this way, the link can specify the path of movement at least to one side. However, the link can also be essentially as wide as the drive pin.Then the trajectory can be defined on two sides.

[0023] At least one narrow point can be formed within the link, where the link is less wide than the drive pin. The narrow point can be formed by a local elevation on at least one of the side surfaces of the link. The elevation can be arranged in particular on the side surface along which the drive pin does not slide during movement. The drive pin can pass through the narrow point by slightly spreading the link at the narrow point, i.e. elastically deforming the elevation. The narrow point can spring back again behind the drive pin. The narrow point can, for example, be arranged shortly before the end of the movement path in order to secure the drive pin in an end position.

[0024] The initial section of the guide can be extended to an edge. This allows the drive pin to be positioned within the guide during assembly of the connector. The initial section can be located outside the path of travel and, for example, be separated from the path of travel by a narrow section. The initial section can also be curved.

[0025] A pivot point of the lever can be designed as a bearing pin. The bearing pin can be formed on the connector housing or on the lever and arranged in a recess in the lever or the connector housing. The bearing pin and the recess can have a circular cross-sectional area, at least in some areas.

[0026] An output element can be a recess or a projection in the lever. A counterpart can have a contour matching the output element.

[0027] According to the invention, the output element has a support surface for supporting the output force on the counterpart, wherein the support surface is arranged laterally offset from the counterpart in an initial position of the lever when the plug is placed on the header, wherein the support surface is pivoted behind the counterpart by the rotational movement and the positive connection between the support surface and the counterpart is established.

[0028] In an initial position, the lever can be aligned essentially in the plug-in direction or slightly diagonally to the plug-in direction. The rotational movement can begin at the initial position. The rotational movement allows the lever to be rotated transversely to the plug-in direction. For example, the lever can be rotated essentially perpendicular to the plug-in direction. The lever can also be rotated more or less than perpendicular to the plug-in direction. The lateral offset in the initial position allows the counterpart to move past the support surface when the plug is placed on the header. Due to the lateral offset, there can be no contact between the support surface and the counterpart at the beginning of the rotational movement. For example, the lever can be rotated between 30° and 50° before the support surface rests on the counterpart. Until then, the drive movement can essentially only occur against the frictional resistance of the plug mechanism.

[0029] The support surface can slide against the counterpart due to the rotational movement. The support surface can roll against the counterpart similar to a tooth on a gear, sliding along it. A sliding component of the movement can be determined by the shape of the support surface and the counterpart. The rolling movement can convert the rotational movement back into a linear movement. The linear movement can be used to pull the connector toward the header.

[0030] The output element can have a stop surface for the counterpart, opposite the support surface. The stop surface can be aligned with the counterpart in the initial position of the lever and rest against the counterpart when the connector is placed on the header. The stop surface can be lifted off the counterpart due to the rotational movement. The stop surface can serve as a depth stop when the connector is placed on the header. The stop surface can define a pre-locking position of the connector. The rotational movement can move the stop surface away from the counterpart.

[0031] The output element can be designed as a recess in the lever. The support surface and the stop surface can be arranged on opposite sides of the recess. The counterpart can be arranged in the recess in the initial position. The recess can be open towards the counterpart in the initial position and can be rotated laterally around the counterpart by the rotational movement. The recess can be larger than a tooth gap of a gear. The support surface and the stop surface do not lie against the counterpart at the same time.

[0032] The slider can be locked in an initial position by a locking mechanism. The locking mechanism can be released when the connector is placed on the header and the counterpart is positioned in the area of ​​the output element. A locking mechanism can block the drive movement as long as it is not released. The locking mechanism can protect the connector mechanism from unintentional use. The locking mechanism can be a rocker lever, for example, which is actuated by a projection on the header and releases a notch on the slider.

[0033] The gate can be positioned at an angle of between 89° and 80° to the insertion direction. By positioning the gate at an angle, the rotary motion can begin without jerking the drive pin in the gate. This angle creates a lateral force component of the drive force on the drive pin.

[0034] The slider can engage in a final position on the connector housing. The slider and the connector housing can have a locking device that holds the slider and thus the rest of the mechanism in the final position. The locking device can be locked in the locked position by a manually operable lock.

[0035] The connector can have two levers. The levers can be located on opposite sides of the connector. Having two levers reduces the force on each lever. This allows the overall mechanism to be smaller.

[0036] The levers can be arranged diagonally opposite each other on the connector. This diagonally opposite arrangement allows the output forces to be distributed symmetrically on the header. This prevents asymmetric torque. The connector and header can be mated evenly. Short character description

[0037] Advantageous embodiments of the invention are explained below with reference to the accompanying figures. They show: Fig. 1 shows a connector mounted on a header according to an embodiment; Fig. 2 shows a connector mated to a header using a force amplifier according to one embodiment; Fig. 3 shows a slider for a plug according to an embodiment; and Fig. 4 shows a lever for a plug according to an embodiment.

[0038] The figures are schematic representations and serve only to illustrate the invention. Identical or equivalent elements are provided with the same reference numerals throughout. Detailed description

[0039] Fig. 1 shows a connector 100 according to an exemplary embodiment, which is placed in a pre-locking position onto a corresponding header 102. In the pre-locking position, the connector 100 and the header 102 are aligned and rest against one another, but are not yet plugged together to form a plug connection. The connector 100 has a connector housing 104, a slide 106, and at least one lever 108. The slide 106 is movably mounted on the connector housing 104 in a plugging direction 110 of the connector 100 or the plug connection. The slide 106 encloses the connector housing 104 in a ring-shaped manner. The connector housing 104 is arranged in an interior of the slide 106. The slide 106 has a substantially rectangular cross-section with rounded corners. The slide 106 serves as a handle for plugging the plug connection together.

[0040] The lever 108 is arranged in a space between the slide 106 and the connector housing 104. The lever 108 is rotatably mounted on the connector housing 104 and engages with a drive pin 112 in a slotted guide 114 of the slide 106, which is oriented substantially transversely to the plugging direction 110. The drive pin 112 is oriented transversely to the lever 108. At a pivot point 116 of the lever, the lever 108 has a drop-shaped recess in which a bearing pin of the connector housing 104 is arranged. The bearing pin has a drop-shaped end plate. Thus, the lever 108 can only be pushed onto the bearing pin in one position. If the lever 108 is rotated from this position, it cannot slip off the bearing pin.

[0041] Here, the slider 106 and the lever 108 are arranged in an initial position 118, and the connector 100 is arranged in the pre-locking position on the header 102. An output element 120 of the lever 108 is arranged in the region of a corresponding counterpart 122 of the header 102. The output element is arranged on a side of the pivot point 116 opposite the drive pin 112. The output element 120 is placed on the counterpart 122, but in the initial position 118, it cannot yet transmit any force to the counterpart 122.

[0042] When the slide 106 is moved with a linear movement 124 in the insertion direction 110, the drive pin 112 slides along the slotted guide 114 and drives a rotary movement 126 of the lever 108. The rotary movement 126 creates a positive connection between the output element 120 and the counterpart 122. When the output element 120 rests positively against the counterpart 122, a drive force 128 is transmitted from the slide 106 to the drive pin 112 via the slotted guide 114. The drive force 128 is translated via a lever ratio of the lever 108 into an output force 130 on the output element 120 and supported on the counterpart 122. A counterforce 132 to the output force 130 and the drive force 128 are supported on the connector housing 104 via the pivot point 116 and move the connector housing 104 in the plugging direction 110.

[0043] The leverage ratio here is approximately 4:1. The driving force 128 is thus roughly quadrupled.

[0044] In one embodiment, the counterpart 122 is shaped approximately like a single tooth of a rack. The output element 120 essentially corresponds to an enlarged gap between two teeth of a gear. In the pre-locking position, the output element 120 rests with a stop surface on an upper side of the counterpart 122. Due to the rotational movement 126, the stop surface lifts off the counterpart, and a support surface 134 of the output element 120 is pivoted behind or below the counterpart 122 against an underside 136 of the counterpart 122 by the rotational movement 126. The support surface 134 then rests against the underside 136 with a positive fit, and the output force 130 is supported by the support surface 134 on the underside 136. When the rotational movement 126 is then continued, the support surface 134 slides along or over the underside 136.

[0045] In one embodiment, the connector housing 104 has at least one locking mechanism 138 for the slider 106. The locking mechanism 138 prevents the linear movement 124 until it is released when the connector 100 is placed onto the header 102, releasing the slider 106. The locking mechanism 138 is designed here as a rocker lever, which is slightly rotated when it strikes a rib 140 provided for this purpose on the header 102 during placement. This rotation pushes back a locking pawl, releasing the slider 106.

[0046] In one embodiment, the link 114 is aligned obliquely to the insertion direction 110. Due to the inclination, a lateral force acts on the drive pin 112 already at the beginning of the linear movement 124 of the slide 106 and initiates the rotational movement 126.

[0047] Fig. Figure 2 shows a connector 100 mated with a header 102 using a force amplifier according to an embodiment. The connector 100 and the header 102 are mated together to form the connector 200. The connector 100 and the header 102 essentially correspond to the illustration in Fig. 1.

[0048] The slider 106 and the lever 108 are arranged here in an end position 202. In the end position 202, the drive pin 112 has reached one end of the guide 114, and the lever 108 is positioned in the end position 202 essentially transverse to the plugging direction 110. The connector housing 104 has been pushed onto the header 102 by the counterforce 132. The slider 106 has been pushed over the connector housing 104 in the plugging direction 110.

[0049] In one embodiment, the slider 106 is locked into the end position 202 on the connector housing 104. This locking action prevents the connector 200 from becoming loose.

[0050] In one embodiment, the slider 106 is additionally locked to the connector housing via a secondary lock 204. The secondary lock 204 can only be opened with a special tool. This prevents unauthorized removal of the connector 200. The secondary lock 204 can be operated manually, for example.

[0051] In one embodiment, the connector 100 has a lever 108 on each of two opposite sides. The pivot points 116 are arranged in the area of ​​diagonally opposite corners of the connector housing 104. The guides 114 extend from the corners along the walls of the slider. The two levers 108 transmit the counterforces 132 into the connector 100 essentially symmetrically to a center of gravity of the extender 100, thus preventing the connector 100 from tilting or jamming on the header 102.

[0052] Fig. Figure 3 shows a slider 106 for a connector according to an embodiment. The slider 106 essentially corresponds to the slider in Fig. 1 and Fig. 2. The slider 106 has two diagonally opposite guides 114. The guides 114 are arranged on the long sides of the rectangular slider 106. The guides 114 each have two notches 300, with a first notch 300 separating a curved initial section 302 of the guide 114 from a straight working section 304. When assembling the connector, the drive pins of the levers are inserted into the initial sections 302 and slide along the initial sections 302 to the first notch 300. At the first notch 300, increased force is required to allow the drive pin to slide over the notch 300. In the process, the guide 114 is slightly elastically deformed. After the drive pins have moved over the first notches 300, they are at the beginning of the working section 304 and thus in the starting position.

[0053] When the connector is mated with the header, the drive pins slide along the working sections 304 to the second notches 300. The second notches 300 are again overcome by an increased force, whereby the guides 114 also undergo a slight elastic deformation. After overcoming the second notches 300, the drive pins are in their final position.

[0054] On one narrow side, the slider 106 has a locking element 306 for locking onto the connector housing. The locking element 306 locks onto the connector housing when the slider 106 has reached its end position. The locking element 306 can be released again by pressing a pressure surface 308, thus opening the plug connection. The locking element 306 is therefore protected from incorrect operation by the secondary locking mechanism.

[0055] The slider 106 has four locking pawls 310 which are unlocked by the locking mechanism when the plug is placed on the header in order to enable the linear movement.

[0056] Fig. Figure 4 shows a lever 108 for a connector 100 according to an embodiment. The lever essentially corresponds to the lever in Fig. 1 and Fig. 2. The lever 108 has the drive pin 112 at the end of its drive lever arm 400. The lever 108 has the output element 120 on an output lever arm 402 arranged offset by approximately 135° around the pivot point 116 relative to the drive lever arm 400.

[0057] The drive pin 112 is oriented like a crank transversely to the drive lever arm 400 and on an outer side of the lever 108, essentially parallel to a rotational axis 404 of the lever 108. The drive element 120 is arranged on an opposite inner side of the lever 108. The output element 120 is designed as a recess in the lever 108 and essentially corresponds to a tooth gap between two teeth of a gearwheel formed around the rotational axis 404. The stop surface 406 and the support surface 134 form the opposite flanks of the tooth gap.

[0058] In the pre-locking position, the stop surface 406 rests against the counterpart, which is essentially shaped like a single tooth of a rack. During the rotational movement of the lever 108, the tooth gap engages the counterpart, and the support surface 134 forms a positive connection with the underside of the counterpart and slides against the counterpart during the rotational movement.

[0059] In the following, possible embodiments of the invention are summarized again or presented with slightly different wording.

[0060] A force reduction on the connector without increasing the installation space is presented.

[0061] This achieves a similar installation space as with a connector without insertion force reduction.

[0062] In the approach presented here, the connector is moved by two levers on the interface. The levers are moved in the plugging direction by a slider. The interface releases the slider, and the slider locks into the final position with the outer housing, releasing the CPA (secondary fuse).

[0063] To reduce the insertion force, levers with pins on the interface or levers with gears are conventionally used. Similarly, a lever can move a slider, or a slider can move a lever, and the force reduction curve is realized via the interface.

[0064] The approach presented here can be used for all connectors that are space-critical and require force reduction. The approach presented here allows for a smaller installation space.

[0065] The connector presented here has two levers and a slider. The interface has no force reduction curve.

[0066] The lever shown has a locking element with the interface, a connection with the slider, and a rotation point. The slider has a locking element with an outer housing of the connector and a lever travel for each lever.

[0067] The connector is placed onto the interface in a pre-locking position. The slider is moved in one direction of the connector until the levers pull the connector into a mated position.

[0068] Since the devices and methods described in detail above are exemplary embodiments, they can be modified widely by those skilled in the art without departing from the scope of the invention. In particular, the mechanical arrangements and the relative dimensions of the individual elements are merely exemplary.
