Description

  • The invention relates to a for electrical plug connection with a plug, in particular with a arranged on a charging cable for an electric vehicle plug, and a power outlet, in particular a power outlet, provided adapter.
  • The electrical energy required to move electric vehicles is stored in batteries. These accumulators can be charged at publicly available charging stations via a cable connection. Since such charging stations are not yet available everywhere, about 90% of the charging processes are still carried out in private households or at the workplace. In this case, the batteries of the electric vehicle are connected via a charging cable available as an accessory to a standard household power outlet. On the one hand, this charging cable must have a plug for plugging into a socket on the vehicle side and a power plug designed for the respective country standard for plugging into the power outlets of different design according to the country standard.
  • It has already been thought to provide corresponding adapter, by means of which the charging cable can be connected to the respective country-side power outlets. In known adapter solutions, however, it proves to be disadvantageous that a contact or a connection and a disconnection of the charging cable plug from the adapter in the energized state, so if the adapter is in the socket, can take place. As a result, there is a possibility that a gap is formed between the charging cable plug and the adapter, through which a current-carrying contact of the adapter or the plug can be touched with a screwdriver or a wire. For this reason, the known solutions do not meet the required in the context of charging electric vehicles standard (IPXXD), according to which such connectors must have increased safety in use and protection against contact.
  • From the EP 1 527 501 B1 already a charger for rechargeable batteries is known. On the housing of the charger can be exchangeably attached to the respective country standard adapted as an adapter power plug. Here, both the housing and the power plug on matched coupling means for producing a connector.
  • Other adapters are also from the DE 87 02 758 U1 , of the DE 20 2011 051 961 U1 and the US 4,484,185 A known.
  • The invention has for its object to provide an adapter with increased safety in use and protection against contact of the electrical contacts. At the same time, the requirements stipulated in the standard, which also apply in particular to the charging of rechargeable batteries of electric vehicles, should be fulfilled. Furthermore, the invention has for its object to provide an appropriately designed connector for connection to the adapter.
  • The first object is achieved with an adapter according to the features of claim 1. The dependent claims 2 to 8 relate to particularly expedient developments of the invention.
  • According to the invention, an adapter is provided which has a movably mounted securing element, which is displaceable by a plugging operation of the adapter into the socket from a first position to a second position, wherein the plug connection between the plug and the adapter exclusively in the first position arranged fuse element can be produced and wherein the fuse element arranged in the second position is on the one hand designed to prevent production of the plug connection between the plug and the adapter and on the other hand is adapted to intervene in such a way, in particular a form-fitting, in a recess of the plug that a Disconnecting the connector already made before the displacement of the fuse element between the plug and the adapter is not possible. Just by plugging the adapter into the socket so the fuse element is necessarily and automatically transferred to the second position, thereby preventing a connection or disconnection of the plug from the adapter in the energized state. By locking between the plug and the adapter is achieved that the plug and the adapter in the energized state gapless rest against each other, so that it is not possible to touch the current-carrying contact surfaces of the adapter or the plug or the connector with a wire or screwdriver , As a result, the safety of use of the adapter is increased and at the same time ensures optimum protection against contact of the electrical contacts. In addition, the requirements for charging electric vehicles specified in the standard are met.
  • A functionally particularly advantageous embodiment of the present invention provides that the securing element with a in the direction of first position directed force is applied, so that the securing element against this force from the first position to the second position is displaced. This ensures that the fuse element in the non-energized state, so if the adapter is not plugged into the socket, always in the first position and the plug can be easily arranged on the adapter or disconnected from the adapter.
  • In this case, it has proven to be particularly practical that the force can be generated by a spring, in particular a helical spring. By the spring, a particularly reliable arrangement in the first position and at the same time a process-safe provision of the arranged in the second position fuse element is ensured in the first position. The spring force is interpreted in such a way that the spring does not hinder the insertion of the adapter into the socket and the force is insufficient to push out the adapter from the plug.
  • The securing element can be displaced from the first position to the second position by a pivoting movement or a rotational movement. Another particularly useful modification of the invention, however, is achieved in that the securing element is displaceable by a translational movement from the first position to the second position, which is aligned in particular parallel to a plug-in plug into the socket of the adapter. As a result, a space-optimized arrangement of the displaceable securing element is ensured, so that the dimensions of the adapter in comparison to an adapter without a fuse element hardly or not change.
  • In this case, it proves to be particularly advantageous that the securing element comprises a movably mounted in the adapter, in particular cylindrical pin. In this case, the pin can be arranged space-optimized inside the provided for the provision in the first position coil spring. In this case, a projection or a shoulder is then arranged on the pin, on which the spring is supported. The other end of the spring then bears against a stationary component, for example a housing component, of the adapter. Upon movement of the pin from the first position to the second position, the spring is compressed between the projection and the housing component. When pulling out the adapter from the socket, the pin is moved back by the spring in the first position, so that the spring returns to its relaxed starting position.
  • From a constructive and functional point of view, it also proves to be particularly useful if the arranged in the first position fuse element protrudes from the adapter so that it is supported during the insertion of the adapter into the socket on a surface of the socket or a socket limiting surface , As a result, the fuse element contacted during a feed movement of the adapter in the direction of the socket inevitably a surface of the socket and is automatically transferred during the further insertion movement of the adapter in the direction of the socket in the second position in which then the plug connected to the adapter is locked to the adapter or a production of a plug connection between the adapter and the plug is prevented.
  • It is further provided that the adapter has at least one contact means for making electrical contact with the plug, wherein an access opening to the contact means by a movably mounted protective element can be covered, which during manufacture of the connector between the plug and the adapter of the access opening covering position against a Restoring force in the access opening at least partially releasing position can be transferred. As a result, an optimal contact protection is provided for the case that the adapter is energized, that is plugged into the socket, but no plug is in the adapter. At the same time, penetration of dirt or foreign particles into the access opening is effectively prevented by the protective element. The protective element can be transferred by a pivoting movement or by a translational movement of the covering position in the access opening at least partially releasing position.
  • In this case, it proves to be particularly advantageous that in addition to the access opening to the contact means at least one further functional opening is provided, in which engages a component of the plug during the production of the plug connection between the plug and the adapter. In this case, the component of the plug contacts the protective element during a relative movement between the plug and the adapter and thereby displaces the protective element in a position releasing the access opening, so that the contact element of the plug can be inserted into the access opening without touching the protective element.
  • The second-mentioned object is achieved with a plug according to the patent claim 9. The dependent claim 10 relates to a particularly advantageous development of the invention.
  • According to the invention, therefore, a plug is provided for connection to an adapter, which at least one contact element for electrical Having connection with a contact means of the adapter and at least one recess for in particular positive reception of a securing element of the adapter. By such a configuration of the plug, a reliable locking of the plug to the adapter can be achieved with simple means. To lock the fuse element engages during the displacement of the first position to the second position in the recess and prevents in the second position, a separation of the connector between the plug and the adapter.
  • An alternative embodiment of the plug provides that it has a provided for insertion into a functional opening of the adapter mandrel, which is designed such that a access opening to the contact means of the adapter covering and movably mounted protective element is displaced into a position releasing the access opening, wherein the recess for receiving the securing element is arranged in the mandrel. In this case, the function of locking and the function of shifting the protective cover of the adapter is integrated in a single component, whereby the dimensions of the connector can be optimized.
  • In summary, it is stated that the invention can be used in particular when charging accumulators of electric vehicles, wherein the charging cable on the vehicle side can be connected by a plurality of differently designed adapter to the respective country standard formed power outlets. Of course, other uses of the adapter according to the invention are conceivable, especially in cases where increased safety in use and contact protection, for example in high-voltage connections, is required.

  • The 1 to 8th show different representations of a first embodiment of an adapter according to the invention 1 , 1 shows a schematic diagram of the adapter 1 in a side view, which, as in 3 is shown, for electrical plug connection with a plug 2 and a power outlet 3 is provided. The plug 2 is with a charging cable 4 connected to an electric vehicle, not shown. The power outlet 3 is designed as a household power outlet. The adapter 1 has a movably mounted and formed as a cylindrical pin securing element 5 on which of the in 1 shown first position in the in 2 and 3 shown second position can be moved. The fuse element 5 is acted upon by a directed in the direction of the first position force F, so that it is against the force F from the first position to the second position displaced. The force F is through one in 2 which the detail X out 1 in an enlarged view, shown spring 6 generated. The feather 6 is designed as a helical spring, wherein the securing element 5 is arranged in a limited space of the coil spring. The feather 6 rests between a projection 7 , which firmly with the fuse element 5 is connected, and a fixed component 8th of the adapter 1 , For example, the adapter housing from. 2 shows the relaxed spring 6 at a arranged in the first position fuse element 5 , In this first position, the securing element protrudes 5 , as in 1 can be seen, with an end portion 9 from a surface 10 of the adapter 1 out, in the area in which also the electrical contact with the socket 3 provided pins 11 are arranged.
  • When inserting the adapter 1 into the socket 3 comes the end section 9 of the fuse element 5 initially in contact with a surface 12 the socket 3 or one the socket 3 limiting area. Upon further movement of the adapter 1 in the direction of the socket 3 becomes the security element 5 of the adapter 1 against the force F of the spring 6 moved to the second position. In this in the 3 and 5 shown second position protrudes the end portion 9 opposite end section 13 of the fuse element 5 from one of the power outlet 3 remote surface 14 of the adapter 1 out.
  • If during the insertion process of the adapter 1 into the socket 3 the one with the charging cable 4 connected plugs 2 already with the adapter 1 is connected, engages the end portion 13 of the fuse element 5 in the second position positively in a correspondingly formed recess 15 in the plug 2 and thereby locks the plug 2 on the adapter 1 , The plug 2 can in the in 3 shown second position of the fuse element 5 not from the adapter 1 be separated. A disconnection of the plug connection between the plug 2 and the adapter 1 is exclusively at a arranged in the first position fuse element 5 So if the end section 9 from the adapter 1 stands out, possible. To do this, first the one with the plug 2 connected adapters 1 from the socket 3 be pulled out. Through the on the security element 5 acting force F moves the fuse element 5 then automatically to the first position, the end portion 13 of the fuse element 5 from the recess 15 of the plug 2 is pulled out and the other end section 9 of the fuse element 5 from the adapter 1 moved out to the first position.
  • In the event that the plug 2 in the insertion of the adapter 1 into the socket 3 not with the adapter 1 is connected, so only the adapter 1 into the socket 3 is inserted, the fuse element 5 also, as already described, moved to the second position. However, then the end section protrudes 13 of the fuse element 5 , as in 5 represented, in such a manner in a connection area with the plug 2 into it, that a plug connection between the plug 2 and the adapter 1 can not be produced. A contact or the production of the plug connection between the plug 2 and the adapter 1 is exclusively at a arranged in the first position fuse element 5 possible.
  • In the in the 1 to 8th The first embodiment shown is the production or the separation of the plug connection between the plug 2 and the adapter 1 at a arranged in the second position fuse element 5 therefore not possible because of the adapter 1 and the plug 2 must be moved in a plane relative to each other, which is perpendicular to the longitudinal extent of the contact pins 11 of the adapter 1 extends. The relative movement in exactly this plane is, however, by the in the second position of the fuse element 5 from the surface 14 of the adapter 1 outstanding end section 13 prevents, so that neither a disconnecting nor making the plug connection between the adapter 1 and the plug 2 is possible.
  • Again 7 and the 8th , which is a view along the line AA in 7 shows, it can be seen, the relative movement for producing or for separating the connector between the adapter 1 and the plug 2 both translational, namely in the direction of the arrows 16 , or rotational, namely in the direction of the arrow 17 be trained. The plug connection between adapters 1 and plugs 2 can therefore by a rotary movement (arrow 17 ) or postponing (arrows 16 ) from the two sides, from above or from below. By making the connector then results in an electrical contact between in the adapter 1 arranged and designed as sockets contact means 18 and on the plug 2 arranged and designed as pins contact elements 19 ,
  • The 9 to 17 show a second embodiment of an adapter according to the invention 1 , The to the electrical plug connection with a plug 2 and a power outlet 3 provided adapter 1 is how in 9 shown formed as a cylinder. The adapter 1 also has a movably mounted securing element 5 which can be moved from a first position to a second position. In 9 is the security element 5 arranged in the first position, so that an end portion 9 of the fuse element 5 from a surface 10 a front side 20 of the adapter 1 protrudes. Furthermore, the adapter 1 two out of the surface 10 protruding pins 11 for electrical contact with a in 9 not shown socket 3 on. In a lateral surface 21 of the adapter 1 There are four access openings 22 with a round cross section and a functional opening 23 arranged with a rectangular cross-section. The electrical contact means 18 of the adapter 1 are over to the lateral surface 21 open grooves 24 with the access openings 22 or the functional opening 23 connected. Here is a width of the respective groove 24 smaller than a diameter of the respective access opening 22 , In addition, the adapter points 1 one the access openings 22 , the functional opening 23 and the grooves 24 covering protective element 25 on. The protective element 25 is movable and can be moved from one to 9 illustrated position in which the openings 22 . 23 and the grooves 24 covered in one of the openings 22 . 23 and the grooves 24 be transferred at least partially releasing position. Here, the protective element 25 be pivoted about an axis as well as translationally moved.
  • The in 10 shown and with a charging cable 4 for an electric vehicle connected plug 2 has four T-shaped contact elements 19 and a parallel to the contact elements 19 extending spine 26 on. The contact elements 19 consist of a shaft 27 and one perpendicular to the shaft 27 extending cross member 28 , It is a width or a diameter of the shaft 27 at least slightly smaller than the width of the adapter 1 arranged groove 24 and a width or a diameter of the cross member 28 is at least slightly smaller than the diameter of the access openings 22 in the adapter 1 , A length of the spine 26 is greater than a length of the contact elements 19 , In a charging cable 4 remote area has the mandrel 26 a recess formed as an opening 15 on.
  • For making the plug connection between the plug 2 and the adapter 1 this is initially translational in the direction of the adapter 1 moved (directional arrow 29 in 11 ), in such a way that initially a in 14 shown end portion 30 of the thorn 26 in the function opening 23 of the adapter 1 engages and thereby the movably mounted protection element 25 shifted so that the access openings 22 in the lateral surface 21 of the adapter 1 be released. Upon further movement of the plug 2 in the direction of the directional arrow 29 Then grab the cross elements 28 the contact elements 19 of the plug 2 through the access openings 22 of the adapter 1 therethrough. Subsequently, a rotational movement of the plug then takes place 2 according to the directional arrow 31 in 11 , and that until the contact elements 19 of the plug 2 the contact means 18 of the adapter 1 at the end of the grooves 24 reach and contact them (see 14 ). In this arrangement is a radial movement of the plug 2 relative to the adapter 1 by a positive connection between the contact elements 19 and the grooves 24 not possible anymore.
  • In 12 is a schematic diagram of the adapter 1 shown in a side view. The fuse element 5 is arranged in the first position, wherein the end portion 9 of the fuse element 5 from the surface 10 or from the front side 20 of the adapter 1 protrudes. By a in 13 which the detail X out 12 in an enlarged view, shown force F is the securing element 5 held in the first position. In this case, the force F by a between a projection 7 of the fuse element 5 and the component 8th of the adapter 1 stored spring 6 generated.
  • 14 shows that already with the plug 2 connected adapter 1 , The adapter 1 is not in the socket yet 3 arranged so that the fuse element 5 still in the first position ( 15 ).
  • 16 shows the in the socket 3 plugged adapter 1 with that in the adapter 1 plugged in 2 , When inserting the adapter 1 into the socket 3 the fuse element shifts 5 in the illustrated second position. The fuse element 5 moves in the axial direction, so one end section 13 of the fuse element 5 in the one in the thorn 26 arranged aperture or recess 15 engages This causes the plug 2 on the adapter 1 locked. One to disconnect the connector between the adapter 1 and the plug 2 required rotational movement between the plug 2 and the adapter 1 is no longer possible. During the movement of the fuse element 5 from the first position to the second position becomes the spring 6 , as in 17 shown between the projection 7 and the component 8th compressed.
  • Even if the adapter 1 without the plug 2 into the socket 3 is introduced, the securing element moves 5 in the second position. An assembly of the plug 2 on the adapter 1 However, in this state is not possible because the end section 13 of the fuse element 5 a rotational movement of the plug 2 for the production of the plug connection between plug 2 and adapters 1 blocked.
  • For sealing the plug connection between the adapter 1 and the plug 2 is a seal 32 For example, an O-ring provided between the adapter 1 and the plug 2 is arranged ( 3 ). The seal 32 prevents ingress of liquid, moisture or solid Particles and can be on the adapter 1 ( 5 ) and / or on the plug 2 be arranged or fixed interchangeable.
