[0002] Contact elements for transmitting electrical energy and / or electrical signals are configured differently depending on their intended use and application, and are designed to meet a wide range of requirements. At the same time, contact elements must be electrically insulated and, above all, protected against environmental influences. For example, insulating bodies in the form of so-called touch protection pins or insulating caps are typically used to protect contact elements and ensure electrical safety. One application is charging technology for charging electrically powered vehicles (electric vehicles) with their respective connectors.

[0003] For example, various approaches to the corresponding isolation of contact elements are known from the patent literature of the prior art, with reference to the following publications: DE 10 2020 112 117 A1, DE 10 2017 218 326 A1, CN 203800335 U.

[0005] The problem is solved by the features of claims 1, 11 and 13. Further embodiments and applications of the present invention will become apparent from the dependent claims and are explained in more detail in the following description with partial reference to the figures.

[0006] According to a first general aspect, the present invention relates to an insulating element for mounting on a contact element for transmitting electrical energy and / or electrical signals, comprising: • an actuating section configured for translational and / or rotational actuation of the insulating element substantially along a mounting direction during a mounting process; • a mounting section configured to form a captive screw connection with a retaining section of the contact element in order to position the insulating element in a defined position on the contact element in a mounting state.

[0008] The insulating element can be securely attached to the contact element by means of a screw. In its assembled state, the insulating element may be at least partially deformed and / or subjected to a preload, among other things to create a force-fit connection with the contact element.

[0009] The captive screw connection can be achieved, for example, by a grooving process, i.e., by a cutting process on the insulating element using a thread of the contact element.

[0010] According to a further aspect of the present invention, it can be provided that the actuating section comprises an engagement area for forming a plug connection with a tool, which is configured to absorb and / or transfer to the assembly section, essentially in the assembly direction, an assembly torque and / or an assembly force, preferably a pressing force, of the tool during the assembly process in order to form the captive screw connection with the holding section.

[0023] In particular, by forming a threaded connection, the insulating element can be securely attached to the contact element, preferably in conjunction with a deformation state of the insulating element, which in turn results in a preload state of the insulating element.

The contact element 200 can, for example, be a component of a charging connector of a charging station for charging electrically powered vehicles (electric vehicles). The contact element 200 is described in more detail below with reference to further figures.

[0043] The insulating element 100 is essentially rotationally symmetrical and extends along a longitudinal direction L100. The longitudinal direction L100 can be the direction in and / or along which the insulating element 100 extends to its maximum and thus its longest extent. The insulating element 100 can be designed and / or configured depending on the contact element 200.

[0044] The insulating element 100 is preferably manufactured integrally as a single piece.

The insulating material can be based on a plastic material. The insulating element 100 can be manufactured, for example, by at least one of the following processes: injection molding, casting, sintering, 3D printing, milling, cutting, parting, curing, or shrinking.

[0045] The insulating element 100 is essentially characterized by two sections and their arrangement and configuration. The insulating element 100 comprises the actuating section 101 and the mounting section 102.

[0046] The actuating section 101 is essentially frustoconical in shape. In other words, the actuating section 101 is characterized by a frustoconical surface. The actuating section 101 is preferably formed by means of a tool 300 (see also below). Fig. 7) is configured for translational actuation and / or rotational actuation of the insulating element 100 essentially along an assembly direction M during an assembly operation. In other words, for the assembly operation of the insulating element 100 onto the contact element 200, a linear movement and / or a rotational movement of the insulating element 100, each essentially along the assembly direction M, is provided in order to achieve an assembly state.

[0047] The assembly section 102 is configured to form a captive screw connection with a retaining section 201 of the contact element 200, in order to position the insulating element 100 in a defined position on the contact element 200 during assembly. In other words, the insulating element 100 is attached to the contact element 200 by a screw operation during assembly, i.e., it is captive.

[0048] The defined position can include a defined position and / or orientation of the insulating element 100 relative to the contact element 200. For example, the defined position can include a substantially concentric position of the insulating element 100 to the contact element 200 in an assembly state.

[0049] The captive screw connection can include at least one of the following connections to hold the insulating element 100 in the defined position on the contact element 200 in a captive manner: a friction connection, a clamping connection, a press connection, a threaded connection.

[0051] The actuating section 101 comprises an engagement area 110. The engagement area 110 serves as a coupling area or tool receptacle for forming a plug connection with the tool 300. The engagement area 110 is configured to substantially absorb and / or substantially transmit an assembly torque and / or an assembly force, preferably an assembly pressure force, of the tool 300 during the assembly process, essentially in the assembly direction M, to the assembly section 102.

[0052] To explain in more detail, Fig. 2 the insulation element 100 from Fig. 1 in a second perspective view, in which the formation of the intervention area 110 is particularly clearly visible.

[0053] The engagement area 110 is characterized in a cross-sectional view by a multi-tooth profile. The multi-tooth profile is defined, among other things, by a plurality of grooves, of which in the Fig. 1 and Fig. 2 the groove 111 is shown and labelled. The grooves 111 of the engagement area 110 are arranged spaced apart from each other along a circumferential direction U100 and within the engagement area 110. The grooves 111 extend within or in the area of ​​the actuating section 101 essentially in the longitudinal direction L100. The grooves 111 serve, among other things, for the engagement of complementary springs of the tool 300, which are in Fig. 7 are visible.

[0054] In the Fig. 1 and Fig. In the first embodiment of the insulating element 100 shown in Figure 2, the assembly section 102 comprises a groove area 120. The groove area 120 is designed and configured without threads (before the assembly process), and during the assembly process is threaded by an internal thread 210 of the retaining section 201 (see Figure 2). Fig. 4) to be grooved. In other words, the groove area 120 is configured during the assembly process to form an external thread through an internal thread of the contact element 200, thereby simultaneously forming an essentially positive-locking and essentially force-locking connection.

[0055] The groove area 120 comprises at least one forming projection 121, 122, which extends section by section along the circumferential direction U100 and / or along the longitudinal direction L100. The at least one forming projection 121, 122 is unthreaded in an initial state of the insulating element 100. The at least one forming projection 121, 122 is configured for thread forming through the internal thread 210 of the retaining section 201. The at least one forming projection 121, 122 can, for example, be designed as a web, a rib, or a shoulder, preferably raised.

[0056] During a screwing operation by the translational and / or rotational actuation of the actuating section 101 via the engagement area 110, a thread in the form of an external thread can be cut through the internal thread 210 of the contact element 200 into the at least one forming section 121, 122, whereby a threaded connection with the contact element 200 is formed during the assembly of the insulating element 100.

[0057] The internal thread 210 of the retaining section 201 can, for example, be designed as a fine thread. The respective thread flanks of the internal thread 210 can be characterized in a cross-sectional view, for example, by a V-shaped or U-shaped contour.

[0058] Fig. Figure 3 shows the insulation element 100 for further illustration. Fig. 1 in a perspective sectional view.

[0059] The grooves 111 extending in the longitudinal direction L100 of the engagement area 110 for forming the multi-tooth profile for the engagement of the tool 300 to form a plug connection are clearly visible.

[0060] Furthermore, the presentation in Fig. 3, that the insulating element 100 comprises a mounting channel 103. The mounting channel 103 extends in the longitudinal direction L100 of the insulating element 100 through the actuating section 101 and through the mounting section 102 to penetrate the insulating element 100. The mounting channel 103 is configured to guide a guide element 301 of the tool 300 along the longitudinal direction L100. In other words, a plug connection with the guide element 301 can be realized through the mounting channel 103 in the longitudinal direction L100, which serves to position the insulating element 100 in a defined manner on the contact element 200 via the guided tool 300, preferably during the assembly process in which the insulating element 100 is moved both translationally and rotationally along the assembly direction M. The mounting channel 103 is essentially cylindrical, at least within the mounting section 102.

[0061] Furthermore, the representation in Fig. 3 the form feature 121, which on the one hand (in an initial state) is designed without threads, and on the other hand is configured to produce a thread by a forging process. The forging process includes a cutting operation.

[0062] The actuating section 101 is raised above the mounting section 102. In this embodiment, the actuating section 101 is characterized by a frustoconical configuration. In other words, the actuating section 101 forms an insulating cap for the contact element 200. The actuating section 101 preferably forms a stop 140 for the insulating element 100 on the contact element 200, in order to position the insulating element 100 in the defined position on the contact element 200 during assembly.

[0063] Fig. Figure 4 shows the insulating element 100 and the contact element 200 in an assembly state and in a sectional view, with the contact element 200 partially shown.

[0064] From the presentation in Fig. 4 shows that the insulating element 100 is arranged in a defined position on the contact element 200, wherein the actuating section 101 forms a stop 140 for the insulating element 100 on the end face 202 of the contact element 200.

[0065] In the assembled state, the captive screw connection between the grooved area 120 of the insulating element 100 and the internal thread 210 of the contact element 200 is formed by a screwing process, which is accompanied by a thread forming process.

[0066] The insulating element 100 is screwed into the contact element 200. In this state, a preload can be generated within the insulating element 100, which additionally exerts a respective compressive force (press force) on the internal thread 210 and / or at least the end face 202 of the contact element 200.

[0067] Fig. Figure 5 shows a second embodiment of the insulating element 100 according to the present invention in a perspective view, which is at least partially essentially identical or at least very similar to the first embodiment of the insulating element 100. To avoid repetition, reference is made to the description of the first embodiment of the insulating element 100.

[0068] The insulation element 100 in Fig. However, 5 differs from the insulation element 100 in the Fig. 1, Fig. 2, Fig. 3 to Fig. 4 by the fact that the insulating element 100 comprises a threaded section 130. The threaded section 31 comprises at least one external thread 131, 132, which extends section by section along the circumferential direction U100 and / or along the longitudinal direction L100. The at least one external thread 131, 132 is configured to form an associated internal thread 210 of the retaining section 201 of a contact element 200.

[0069] Fig. Figure 6 shows the insulation element 100 made of Fig. 5 in a sectional view.

[0070] The frustoconical configuration of the actuating section 101 is clearly recognizable. The actuating section 100 transitions directly into the assembly section 102 along the longitudinal direction L100.

[0071] Furthermore, the presentation in Fig. 6, that the actuating section 101 is raised relative to the mounting section 102 and preferably forms a stop 140 of the insulating element 100. In other words, the actuating section 101 forms an insulating cap for the contact element 200.

[0072] The thread flanks of the external threads 131, 132 visible in this cross-sectional view are characterized by an essentially V-shaped contour.

[0073] Fig. Figure 7 shows a tool 300 for mounting the insulating element 200 according to the present invention to a contact element 200 according to the present invention in a perspective view.

[0074] The tool 300 is essentially characterized by the guide element 301 and by the drive section 310 for actuating the actuating section 101 of the insulation element 100.

[0075] The guide element 301 is cylindrical, preferably pin-shaped, and extends along a longitudinal direction of the tool 300 out of the drive section 310 and / or transitions directly into it.

[0076] The drive section 310 is characterized by a hollow cylindrical outer wall and comprises a drive structure 311, which is essentially complementary to the design of the engagement area 110 of the actuating section 101 of the insulation element 100, i.e. to the multi-tooth profile, in order to be able to form a plug connection essentially in the assembly direction M.

[0077] The tool 300 is characterized by a comparatively simple design and is configured to actuate the insulating element 100 on the contact element 200.

[0078] Fig. Figure 8 shows the tool 300. Fig. 7 and the insulation element 100 made of Fig. Figure 5 in a perspective view. The tool 300 is positioned to perform an assembly operation on the insulation element 100.

[0079] Fig. Figure 9 shows the tool 300 and the insulating element 100 for further illustration. Fig. 8 in a perspective sectional view.

[0080] The guide element 301 of the tool 300 is arranged within the assembly channel 103 and penetrates both the actuating section 101 and the assembly section 102 of the insulating element 100 along the longitudinal direction L100. The guide element 301 of the tool 300 is designed such that it projects section by section beyond the assembly section 102 in the longitudinal direction L100. This projecting part of the guide element 301, in turn, serves to guide the insulating element 100 to a contact element 200 during an assembly process.

[0081] Figure 10 shows the tool 300 and the insulating element 100 from the Fig. 8 and Fig. 9, as well as a second embodiment of the contact element 200 in a perspective sectional view.

[0082] The contact element 200 includes a guide channel 220 for the guide element 301, which is designed to be complementary to the guide element 310 and ensures a defined alignment of the tool 300 and, consequently, of the insulating element 100 during the assembly process.

[0083] The present invention provides an insulating element 100 for a contact element 200 for the transmission of electrical energy and / or electrical signals, which can be securely attached to the contact element 200 by means of a simple design and simple assembly.

[0084] The present invention is not limited to the embodiments described above. Rather, a multitude of variants and modifications are possible, which also make use of the inventive concept and therefore fall within the scope of protection. Preferably, the present invention also claims protection for the subject matter and features of the dependent claims independently of the referenced claims.
