Description

Technical Field

[0001] This invention relates to a socket, preferably a charging socket, having a housing and an actuator releasably and fixably or releasably fixed to the outside of the housing, the actuator for actuating a locking element in a locked position to lock the socket together with a plug, preferably a charging plug, wherein the housing includes a passage for guiding the locking element through the housing, wherein the passage is constructed to penetrate the housing and arranged within a sealed area of ​​the housing. The invention also relates to a configuration consisting of a socket and a plug, and a vehicle having the socket, preferably an electrically driven vehicle. Background Technology

[0002] The configuration of a charging plug and charging socket, featuring an electromechanical locking system, is known from existing technology in the electric vehicle field. This locking system is used to lock the charging plug and charging socket together during the charging process of an electric vehicle.

[0003] For example, European patent application EP 2 955 793 A1 describes a vehicle configuration consisting of a charging plug and a charging socket. The charging socket is located on the side of the vehicle and has a locking section outside the sealed area for locking with the charging plug. To achieve locking, an actuator is installed outside the housing of the charging socket in the side / edge area where the charging socket is connected. This actuator includes an operable cylindrical locking bolt that locks the charging plug in the locking section in a locked state during the plug-in connection process.

[0004] A socket for electric vehicles is known from German patent application publication DE 10 2015 116 649 A1. This socket has a locking hole in the flat side area of ​​the plug-in surface on the plug-in section, i.e., on the contact socket with the contact element. A locking pin of the charging plug can be inserted into the locking hole to lock the charging plug to the charging socket. In the area of ​​the socket opposite the plug-in surface, a contact guide device for inserting the contact plug is provided on the outer casing wall opposite to the locking hole.

[0005] German patent application publication DE 10 2014 100 640 A1 discloses a charging socket having an actuator module and a lighting module arranged laterally, i.e., on the outside of the charging socket's housing. The actuator module is configured to lock a plug inserted into the charging socket within the socket during charging. This is achieved through an opening on the outside of the housing, on which the actuator module is disposed. The actuator module guides a locking device through the opening into the housing.

[0006] Countries such as the People's Republic of China and the United States of America require the use of locking systems with locking pins or bolts through relevant standards (e.g., GB / T 20234.2 and SAE J-1772). In such locking mechanisms, actuators are located outside and on the side of the charging socket housing to guide the locking pin or bolt horizontally or vertically. In this case, the locking pin or bolt does not pass through the sealed area or, preferably, the dry area of ​​the charging socket, but is guided externally, in which, for example, electronic and / or electromechanical components and elements are located. Furthermore, the actuator used to operate the locking pin or bolt is powered and controlled by an external, and therefore additional, electrical conductor. Especially in the case of combined AC / DC charging sockets, the actuator typically requires a relatively large structural space.

[0007] As requirements increase and functions become more numerous, charging sockets, for example, must utilize circuit boards to house more electrical, especially electronic, components and elements. This includes internal contact and control of the actuators for the locking mechanism. Summary of the Invention

[0008] In view of this, the object of the present invention is to provide an improved socket.

[0009] The solution of the present invention for achieving the above-mentioned objectives is characterized by the independent claim. Other embodiments and applications of the invention are described in detail in part with reference to the accompanying drawings.

[0010] According to a first general aspect of the socket, the present invention preferably relates to a charging socket having a housing and an actuator releasably and fixably or releasably fixed to the outer side of the housing, preferably on the outer side of the housing opposite to the plug-in surface of the socket, the actuator for actuating a locking element in a locked position to lock the socket together with a plug, preferably a charging plug, wherein the housing includes a passage for guiding the locking element at least through and / or beyond the housing, wherein the passage is configured to penetrate the housing, preferably configured to form an opening in the housing, and is arranged inside a sealed area of ​​the housing.

[0011] This, for example, provides a socket characterized by an optimized and preferred space-saving structure. In other words, the socket of the present invention preferably improves the utilization of structural space.

[0012] The housing and its walls and / or sections are preferably made at least partially of an insulating material, preferably a plastic-based insulating material. The housing may be formed, for example, by at least one injection molding process and / or at least one casting process.

[0013] The actuator can be configured, for example, as an electromechanical 12V latching actuator or an electromechanical 24V latching actuator.

[0014] The locking element is preferably constructed, at least partially, as a cylindrical locking pin or cylindrical locking bolt, and is configured or sized such that it can withstand, for example, a maximum pull-out force of approximately 150 N when the socket and plug are locked. This preferably prevents the plug from being accidentally or illegally pulled out of the socket. The locking element may be made of a metallic material, or alternatively, a non-metallic material of the same strength.

[0015] The locking position preferably represents a position of the socket and plug, in which the socket and plug form a plug-in connection (i.e., the plug is inserted into the socket) and preferably there is a state in which electrical energy can be transmitted through this plug-in connection.

[0016] The passageway is preferably formed by the wall portion and / or wall segment of the socket housing, and is preferably constructed as a tunnel or channel. The passageway, for example, may extend along the socket's insertion direction from the outer side where the actuator is removably fixed or removably fixed, to the opposite outer side of the socket's insertion surface, thus penetrating the housing.

[0017] Preferably, the passage can be constructed as a circumferentially closed or at least sealed profile that extends through the housing. This prevents, for example, harmful media such as dirt / dust or water from entering the housing through the passage. It also prevents the locking element from coming into contact with other components or elements within the socket housing.

[0018] According to another aspect of the invention, the passage forms at least two openings on the outer side of the housing, wherein preferably, the at least two openings are arranged opposite to each other.

[0019] The locking element can be fed into the passage and guided in the passage by means of an actuator, preferably by at least partial translational guidance, through an opening preferably located on the outer side opposite to the plug surface of the socket.

[0020] The passageway is generally straight and has opposing openings on the outer side of the housing, which facilitates the manufacture of the socket and reduces manufacturing costs. Furthermore, it allows for the optimal guidance of the locking element, preferably preventing obstruction or blockage of the locking element during operation and / or guidance within the passageway.

[0021] According to another aspect of the invention, the passage is constructed to extend through the housing at least partially parallel or inclined to the insertion direction of the socket, preferably along the insertion direction of at least one contact element for transmitting electrical energy and / or electrical signals, and / or the locking element is constructed at least partially parallel or inclined to the insertion direction of the socket.

[0022] This can simplify the manufacturing of sockets, for example.

[0023] This also allows for the provision of corresponding ranges of sockets with different mating surfaces, each having the same or at least substantially the same inner housing section, since only the cross-sections of the passages and / or locking elements need to be configured and / or constructed accordingly.

[0024] According to another aspect of the invention, the sealed region may be constructed as a dry region, wherein at least one contact element for transmitting electrical energy and / or electrical signals is arranged at least partially within the dry region.

[0025] The dry area is preferably constructed as a sealed area of ​​the housing, i.e., the socket, based on insulation requirements. This area is preferably sealed against the environmental medium of the socket, preferably liquid-tight and / or gas-tight. To this end, the sealed area may, for example, have sealing devices on at least partially contacting walls and / or wall segments of the housing, such as sealing devices based on plastic bodies or elastomers.

[0026] This can, for example, protect the components and elements inside the socket housing from harmful media, thereby preventing overall damage to the socket.

[0027] According to another aspect of the invention, the actuator, in a view, preferably in a side view along the insertion direction of the socket, is removably fixed or removably fixed and / or arranged within the contour or projection surface of the housing, preferably within the contour or projection surface of the sealing area on the outer side of the housing.

[0028] This allows for a space-saving placement of the actuator in the socket, thereby ensuring a compact overall structure of the socket.

[0029] According to another aspect of the invention, the housing includes a first housing portion and a second housing portion removably fixed or removably fixed to the first housing portion, wherein the passage is configured to extend through the first housing portion and the second housing portion.

[0030] This allows for relatively simple installation and removal of the socket. Electrical and / or electronic components and elements, such as at least partially at least one contact element, can be housed or contained in a first housing portion that serves as a carrier housing portion, and a second housing portion can be more or less constructed as a cover housing portion of the carrier housing portion. The actuator is preferably releasably fixed or releasably fixed to the outside of the cover housing portion.

[0031] The socket includes at least one sealing device, either partially or partially, between the first housing portion and the second housing portion, in order to form the sealed area.

[0032] The sealing device can be constructed, for example, as a sealing member with a corresponding adhesiveness or as a sealing ring preferably based on plastic.

[0033] The actuator may be configured and / or constructed to operate and / or control via at least one contact element of the socket.

[0034] This eliminates the need for a separate conductor to provide external signal connections and / or power to the actuator. Preferably, the actuator can be powered and / or controlled by electrical and / or electronic components and elements located in the socket.

[0035] According to another aspect of the invention, the locking element is at least partially cylindrical or pin-shaped.

[0036] The locking element is preferably implemented, at least partially, as a cylindrical locking pin or locking bolt. This facilitates, for example, guiding the locking element within the passage, preferably outside its range, i.e., within a dedicated area on the plug for locking the socket and plug together in a plug-in connection state.

[0037] According to another aspect of the invention, the housing has a mounting section on the outer side, preferably on the outer side arranged opposite to the insertion surface of the socket, the mounting section being configured and / or constructed to mount an assembly, wherein preferably, the mounting section is arranged adjacent to the actuator.

[0038] This allows for the removable or removable securing of more or additional electrical and / or electronic components and elements to the mounting section, for example, by means of more housing sections.

[0039] At least one sealing device may be arranged between the actuator and the outer side. The at least one sealing device is preferably arranged or constructed around the opening of the passage.

[0040] This, for example, prevents harmful media, such as water or dirt / dust, from entering the passage at a fixed location between the actuator and the housing and reaching the live components and elements through the passage and / or locking elements.

[0041] According to another aspect of the invention, the passage is preferably made of an insulating material and is at least partially integrally formed, preferably at least partially integrally formed with the first housing portion and / or the second housing portion.

[0042] According to another aspect of the invention, the cross-section of the passage is at least partially generally circular and / or elliptical and / or rectangular.

[0043] A second general aspect of the invention relates to a configuration including the socket disclosed herein, preferably a charging socket, and a plug, preferably a charging plug.

[0044] In order for the plug to form a plug-in connection with the socket disclosed herein and preferably to form a locked position with the socket, the plug is preferably constructed as a mating plugging element of the socket and includes at least one region or section in which a locking element for locking the plug and the socket together can preferably lock the plug in a manner that forms a releasable form-fit connection.

[0045] A third general aspect of the invention relates to a vehicle having the socket disclosed herein, preferably an electrically driven vehicle.

[0046] To avoid repetition, this description is purely for the apparatus of the tool of the present invention and / or the related disclosure features are equally applicable to and can be claimed in the method disclosure, and vice versa. Attached Figure Description

[0057] In the accompanying drawings, identical or functionally equivalent components or elements are designated by the same reference numerals. To avoid repetition, the description of these components or elements is also partially based on the description of other embodiments and / or the accompanying drawings.

[0058] The detailed description of the embodiments shown in the accompanying drawings is for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0059] Figure 1 A schematic diagram, namely a simplified diagram (side cross-sectional view), is shown of an embodiment of the socket 1 of the present invention.

[0060] The socket 1 is preferably configured as a charging socket and is preferably applicable to the field of electric vehicles. Therefore, the socket 1 can be used in electric vehicles (i.e., electric vehicles). Figure 1 It is a component (not shown in the diagram) and is used as an interface for charging electric vehicles.

[0061] The socket 1 includes a housing 100. The housing 100 is preferably made substantially and / or at least partially of a non-conductive material, i.e., an insulating material. The housing 100 has a first housing portion 110 and a second housing portion 120. On the correspondingly configured and constructed end faces of the wall segments, the first housing portion 110 partially contacts the second housing portion 120. Between the first housing portion 110 and the second housing portion 120, i.e., in the contact area, a sealing device is preferably arranged for forming a sealing area 5 of the socket 1. Figure 1 (Not shown in the illustration), which will be explained in detail below.

[0062] The first housing portion 110 is preferably, in particular, detachably connected to or detachably fixed to the second housing portion 120 by means of a screw connection. Figure 1 (Not shown in the drawing).

[0063] The second housing portion 120 has a mating surface 100G. The mating surface 100G includes a mating section 100S in which components and elements for transmitting electrical energy and / or electrical signals are arranged.

[0064] The plug face 100G and the plug section 100S are configured and constructed to work with the charging plug ( Figure 1 (Not shown in the diagram) Establish plug-in connections. Figure 1 In the other accompanying drawings, the insertion direction between the charging plug and socket 1 is indicated by "XS".

[0065] The first housing portion 110 includes an actuator 2 releasably fixed or releasably fixed to the outer side 100A. The actuator 2 is preferably constructed as an electromechanical actuator and includes a locking element 3. The locking element 3 is preferably constructed as a locking pin or locking bolt, and thus has at least a partially cylindrical profile. The actuator 2 is configured and constructed such that the locking element 3 is operated at least partially linearly, i.e., translated and / or rotated along the actuation direction indicated by "XV". With the help of the locking element 3, the plug inserted into the socket 1 can be mechanically locked (not shown in the figures) in a preferably form-fitting connection, preferably during the transmission of electrical energy via the configuration of the socket 1 and the plug, i.e., for example, during the charging of an electric vehicle.

[0066] Preferably, by means of forming a spiral connection and at least partially by a plug-in connection (which will be described in detail in the following figures), the actuator 2 is removably fixed or detachably secured to the housing 100, that is, to the outer side 100A of the first housing portion 110.

[0067] The housing 100, namely the first housing portion 110 and the second housing portion 120, has a passage 4 configured to penetrate the housing 100. The passage 4 is preferably configured as a tunnel or channel. In other words, the passage 4 extends from the outer side 100A of the housing 100, preferably from the back side of the housing 100, through the housing 100 to the oppositely arranged outer side 100A of the housing 100, and preferably to the insertion surface 100G of the housing 100. The passage 4 is configured and correspondingly constructed to guide the locking element 3 through the housing 100 by means of the actuator 2.

[0068] The passage 4, namely the corresponding wall portion and / or wall segment of the first housing portion 110 and the second housing portion 120, is preferably constructed in such a way as to form at least partially a generally cylindrical profile so as to guide the locking element 3 optimally, preferably with almost no gaps.

[0069] like Figure 1 As shown, the passage 4 is distributed or extends within or in the sealed area 5 of the housing 100 of the socket 1. In other words, the passage 4 is constructed and / or arranged in a certain area of ​​the socket 1 (i.e., the housing 100), particularly in conductive components and elements, such as circuit boards or contact elements 6 (see...). Figure 2 It is at least partially housed within the area or arranged within the housing 100.

[0070] Figure 2 A schematic diagram, namely a simplified view (side cross-sectional view), is shown for another embodiment of the socket 1 of the present invention.

[0071] To avoid repetition, the previous combination will not be repeated. Figure 1 The components and elements described are fully explained.

[0072] Similar to Figure 1 Socket 1 is shown schematically. Figure 2 The socket 1 shown also includes a housing 100, which has a first housing portion 110 and a second housing portion 120. Figure 2 The main visible part of the socket 1 is the insertion section 100S of the insertion surface 100G of the second housing portion 120. At least one contact element 6 is provided inside the insertion section 100S, which is used for transmitting electrical energy and / or electrical signals.

[0073] A sealing device 5A is provided between the first housing portion 110 and the second housing portion 120 on the corresponding end faces of the wall portion and / or wall segment, which... Figure 2 The sealing device 5A is highlighted in the image. It may be made of an elastomer, such as silicone resin. The sealing device 5A is preferably distributed along the outer contour of the housing 100 between the first housing portion 110 and the second housing portion 120.

[0074] The sealing device 5A, which is more or less encircling inside the socket 1, forms a sealed area 5, in which the electrical components and elements that need to be protected are arranged.

[0075] The sealing area 5 of the socket 1 is configured and constructed together with the first housing part 110 and the second housing part 120 to prevent harmful media, such as dust / dirt, water and the like, from entering the inner area of ​​the socket 1.

[0076] The passage 4 of the socket 1 extends from the outer side 100A of the housing 100 through the first housing portion 110 and through the second housing portion 120 to the plug surface 100G of the housing 100 having a plug section 100S and accommodates the outer side 100A of the locking element 3, which is used for guiding at least partially in the passage 4.

[0077] At a fixed position between the first housing portion 110 and the second housing portion 120, another sealing device 5B is provided in the area of ​​the passage 4, located between the first housing portion 110 and the second housing portion 120 leading to the passage 4. Furthermore, another sealing device 5C may be arranged between the actuator 2 and the outer side 100A of the housing 100 (i.e., the first housing portion 110) to preferably prevent dirt / dust and / or water from entering at this position.

[0078] By arranging and / or constructing the passage 4 and the corresponding sealing devices 5B and 5C within the sealed area 5 of the socket 1, the plug can be locked in the plugged-in connection state with the socket 1, that is, in the locked position, without damaging other components and / or elements within the socket 1.

[0079] from Figure 2It can also be seen that the actuator 2 is preferably detachably connected to the housing 100 on the outer side 100A of the first housing portion 110 inside the sealing region 5. In other words, the actuator 2 is located within the projection plane of the socket 1 in a view along the insertion direction XS, preferably within the projection plane of the sealing region 5. This achieves, for example, a compact and space-saving structure for the socket 1.

[0080] Figure 3A This is a perspective view (exploded view) of another embodiment of the socket 1 of the present invention.

[0081] The socket 1 also includes a first housing portion 110 and a second housing portion 120, wherein the second housing portion 120 has a plug-in surface 100G with a plug-in section 100S.

[0082] The first housing portion 110 of the housing 100 is disposed and constructed on the outer side 100A, thereby releasably securing the actuator 2. Preferably, the actuator 2 is secured at least partially by means of a plug-in connection between a plug section on the actuator 2 and a mating plug section on the outer side 100A of the first housing portion 110, and by means of a screw connection SV.

[0083] As previously described, the actuator 2 includes a locking element 3 in the form of a cylindrical locking bolt 3, which is used at least for translational manipulation along the actuation direction XV.

[0084] The operating direction XV of the locking element 3 for translational movement is preferably substantially parallel to the insertion direction XS of the socket 1, thereby forming a plug-in connection with the plug. Figure 3A (Not shown in the drawing).

[0085] Figure 3B For the socket 1 of the present invention Figure 3A Rear view of the embodiment shown.

[0086] The figure shows a mounting section 100M on the outer side 100A of the housing 100 (i.e., housing portion 110) of the actuator 2. This section is used to accommodate and mount more components and elements, such as temperature sensors. Figure 3B The view shown along the insertion direction XS of the socket 1 also reveals that the actuator 2 and the locking element 3 in the passage 4 are arranged on or within the housing 100 within the outline or projection surface of the sealing region 5—shown here by dashed lines. For clarity, the outline or cross-section of the passage 4 passing through the first housing portion 110 and the second housing portion 120 is indicated by dashed lines.

[0087] Figure 4A This is a perspective view (exploded view) of another embodiment of the socket 1 of the present invention. As with the previous embodiment, this embodiment is provided with a first housing portion 110 and a second housing portion 120.

[0088] The actuator 2 is releasably fixed to the outer side 100A of the housing 100 with the locking element 3, such that the locking element 3 is located near the wall of the insertion section 100S of the insertion surface 100G based on the configuration of the passage 4. In other words, the passage 4 and the locking element 3 guided in the passage 4 are more or less arranged in the center or central area of ​​the socket 1.

[0092] This invention is not limited to the foregoing embodiments. Rather, numerous variations and modifications can be made that utilize the principles of this invention and thus fall within its scope of protection. This invention preferably also claims protection for the subject matter and features of the dependent claims, regardless of the claims they refer to.
