Description

[Technical Field]

[0001] The present invention relates to a plug connector for a plug connector system, a plug connector system, and a method of forming a plug connector system. [Background technology]

[0002] Plug connector systems are known from the prior art. Summary of the Invention [Problem to be solved by the invention]

[0003] The object of the present invention is to provide a plug connector for a plug connector system, a plug connector system, and a method for forming a plug connector system. This object is achieved by a plug connector for a plug connector system, a plug connector system, and a method for forming a plug connector system, each having the features of the independent claims. Advantageous developments are revealed in the dependent claims. [Means for solving the problem]

[0004] The first plug connector for the plug connector system has a first shield having an engagement portion. The engagement portion is configured to engage within a second shield of a second plug connector. An outer surface of the engagement portion has a mark. The mark is positioned on the outer surface of the first shield so that the mark can be entirely positioned within the area of the through opening of the second plug connector, thereby making the mark completely visible.

[0005] During the assembly of the plug connector system, a problem occurs where the first shield of the first plug connector may move and rotate within the second shield of the second plug connector. Therefore, the first plug connector and the second plug connector may be positioned and oriented in such a way that a proper connection between the first plug connector and the second plug connector cannot be ensured. The first plug connector has a mark so that a proper connection can be reliably implemented. During the mating of the first plug connector and the second plug connector, if the mark is entirely disposed within the through-opening and the mark can be fully seen within the through-opening, it is advantageous to indicate that the position of the first shield of the first plug connector within the second shield of the second plug connector is correct.

[0006] In one embodiment, the first plug connector has a first contact element. The first contact element and the first shield are arranged concentrically. The first contact element is provided to connect to the second contact element of the second plug connector. When the first contact element and the second contact element are mechanically and electrically connected to each other, the mark can be fully seen. The mark is advantageously provided to indicate whether the engaging portion is disposed within the receiving portion such that the first contact element is mechanically and electrically connected to the second contact element.

[0007] In one embodiment, the section of the engaging portion having the mark is longer than the remaining section of the engaging portion. The section having the mark is provided to close the through-opening of the second shield, thereby improving the electromagnetic field compatibility of the plug connector system.

[0008] In one embodiment, the engagement portion has an opening provided to receive the contact lamella of the second plug connector. When the opening is disposed within the area of the contact lamella, whereby the first shield and the second shield can be press-fitted into each other, the mark can be fully viewed. Advantageously, the mark is provided to indicate whether the engagement portion is in the correct position within the receiving portion for the press-fitting of the first shield and the second shield. The shields can be press-fitted into each other only when the opening is disposed within the area of the contact lamella. In that way, the shields are mechanically and electrically connected to each other.

[0009] The second plug connector for the plug connector system has a second shield having a receiving portion. The receiving portion is provided to receive the first shield of the first plug connector. The receiving portion has a through-opening. The through-opening is positioned such that the mark of the first plug connector can be disposed entirely within the area of the through-opening, whereby the mark can be fully viewed. Advantageously, when the mark is disposed entirely within the through-opening and the mark can be fully viewed within the through-opening, it is indicated that the position of the first shield of the first plug connector within the second shield of the second plug connector is correct.

[0010] In one embodiment, the second plug connector has a second contact element. The second contact element and the second shield are arranged concentrically. The second contact element is provided to connect to the first contact element of the first plug connector. When the first contact element and the second contact element are mechanically and electrically connected to each other, the mark can be fully viewed. Advantageously, the mark is provided to indicate whether the first contact element is mechanically and electrically connected to the second contact element.

[0011] In one embodiment, the second contact element has a contact structure designed as a contact fork for receiving the first contact element. The contact structure of the second contact element designed as a contact fork advantageously enables a structure in which the first contact element and the second contact element are arranged orthogonally to each other.

[0012] In one embodiment, the through-opening is arranged within the region of the contact structure of the second contact element, and the contact structure is designed to receive the first contact element. The position of the through-opening advantageously enables an inspection to be carried out during the assembly of the second plug connector. In this case, it is possible to inspect whether the second contact element is positioned such that it can receive the first contact element of the first plug connector.

[0013] In one embodiment, the receiving portion has contact lamellas provided to engage with the opening of the first plug connector. When the contact lamellas are arranged within the region of the opening, thereby enabling the first shield and the second shield to be press-fitted into each other, the mark can be completely viewed. The mark is advantageously provided to indicate whether the engaging portion is in the correct position within the receiving portion for the press-fitting of the first shield and the second shield.

[0014] The plug connector system has a first plug connector according to one of the embodiments and a second plug connector according to one of the embodiments. In this case, the engaging portion of the first shield of the first plug connector engages within the receiving portion of the second shield of the second plug connector.

[0015] In one embodiment, the engaging portion has an opening provided to receive the contact lamellas of the second plug connector. The receiving portion has contact lamellas provided to engage with the opening of the first plug connector. The first shield and the second shield are press-fitted into each other by the opening and the contact lamellas.

[0016] In one embodiment, the first plug connector has a first contact element, and the second plug connector has a second contact element. The first contact element and the first shield are arranged concentrically. The second contact element and the second shield are arranged concentrically. The first contact element and the second contact element are mechanically and electrically connected to each other.

[0017] In one embodiment, the first contact element and the second contact element are arranged orthogonally to each other.

[0018] A method of forming a plug connector system according to one embodiment has the following method steps. The first shield of the first plug connector with the mark is inserted into the second shield of the second plug connector. The mark is arranged within the region of the through-opening of the second shield, and it is confirmed whether the mark can be completely seen within this region.

[0019] In one embodiment, if the mark cannot be completely seen after the confirmation step, the first plug connector is axially moved and / or rotated around the axis to position the mark within the region of the through-opening so that the mark can be completely seen.

[0020] In one embodiment, in an additional method step, when the mark can be completely seen, the first shield and the second shield are press-fitted into each other.

[0021] The present invention described above will be explained in more detail below in connection with the schematic diagrams.

DETAILED DESCRIPTION OF THE INVENTION

[0023] FIG. 1 schematically shows a plug connector system 1 in a perspective view. The plug connector system 1 is designed as a coaxial connection system and can be used, for example, for transmitting data.

[0024] The plug connector system 1 has a first plug connector 100 and a second plug connector 200. The first plug connector 100 is designed as an adapter, for example. For example, a coaxial cable can be connected to the first connection portion 101 of the first plug connector 100. The coaxial cable connected to the first connection portion 101 of the first plug connector 100 can be connected to, for example, a connection portion of a printed circuit board or other device. The second plug connector 200 is connected to a coaxial cable 201, for example. However, the coaxial cable 201 of the plug connector system 1 in FIG. 1 can also be omitted. The first plug connector 100 can also be provided to receive the coaxial cable 201, and the second plug connector 200 can be designed as an adapter.

[0025] The first plug connector 100 has a first shield 102. The first shield 102 can include, for example, copper or another conductive material. The first shield 102 can be plated, for example, with tin, thereby improving, for example, the corrosion resistance of the first shield 102. The first shield 102 can also have another coating, thereby improving corrosion resistance or other properties. The first shield 102 has an engaging portion 103. The second plug connector 200 has a second shield 202. The second shield 202 can include, for example, stainless steel or another conductive material. Similarly, the second shield 202 can be plated, for example, with tin, or can have another coating. The second shield 202 has a receiving portion 203. The engaging portion 103 of the first shield 102 of the first plug connector 100 engages within the receiving portion 203 of the second shield 202 of the second plug connector 200, so the engaging portion 103 cannot be seen in FIG. 1.

[0026] As an example, the plug connector system 1 of FIG. 1 has an angled design, specifically such that the first shield 102 is arranged orthogonally to a portion of the second shield 202 designed to receive the coaxial cable 201. However, this is not essential. The plug connector system 1 can also have a different design. For example, the plug connector system 1 can also have a linear design.

[0027] FIG. 2 schematically shows, in perspective view, the first plug connector 100 and the second plug connector 200 for the plug connector system 1 of FIG. 1. In contrast to FIG. 1, the first plug connector 100 and the second plug connector 200 are not mated.

[0028] During the mating of the plug connector system 1, a problem occurs in that the first shield 102 of the first plug connector 100 may move axially in the first direction 10 within the second shield 202 of the second plug connector 200. Further, the first shield 102 may rotate around the first axis 10 within the second shield 202. Thus, the first plug connector 100 and the second plug connector 200 may be positioned and oriented in such a way that a proper connection between the first plug connector 100 and the second plug connector 200 cannot be ensured. Within the scope of the context of this description, a proper connection refers to a connection that is mechanically stable and reliable in terms of electrical characteristics.

[0029] To overcome this problem, the engaging portion 103 of the first shield 102 has a mark 104. The mark 104 is disposed on the outer surface 105 of the first shield 102. By way of example, the mark 104 has a circular design. However, the mark 104 can also have a different design, for example, the mark 104 can be designed as a cross. The mark 104 can be formed, for example, by a machining process in which the first shield 102 is irradiated with a laser. Alternatively, the mark 104 can also be produced in another way, for example, by a mechanical embossing process, for example, by a stamping process. The receiving portion 203 has a through opening 204. By way of example, the through opening 204 has a circular design. However, the through opening 204 can also have a different design, for example, a rectangular design. The through opening 204 can be produced within the second shield 202, for example, by a drilling process or a punching process.

[0030] FIG. 3 schematically shows the plug connector system 1 of FIG. 1 in a plan view and schematically shows a partial perspective enlarged view of the plug connector system 1 by the area shown in FIG. 3.

[0031] The mark 104 and the through-opening 204 are positioned such that the mark 104 is disposed entirely within the area of the through-opening 204, thereby enabling the mark 104 to be fully viewed. As an example, FIG. 3 shows a scenario where the mark 104 is disposed at the center of the through-opening 204 as an example, and thereby in this case, the first shield 102 engages within the second shield 202 such that the mark 104 can be fully viewed. Thus, in this case, since the first shield 102 engages within the second shield 202 so as to enable a mechanically and electrically secure connection, an appropriate connection between the first plug connector 100 and the second plug connector 200 can be ensured. The dimensions of the engaging portion 103 provided to engage within the second shield 202, and conversely, the dimensions of the receiving portion 203 provided to receive the first shield 102, are determined by the combination of the position of the mark 104 on the outer surface 105 of the first shield 102 and the position of the through-opening 204 in the second shield 202.

[0032] FIG. 4 schematically shows the plug connector system of FIG. 1 in a cross-sectional view. In this case, the cross-section extends along a plane in which the first axial direction 10 and the second axial direction 20 are located, and thus the internal components of the first plug connector 100 and the second plug connector 200 can be viewed in cross-section.

[0033] The first plug connector 100 has a first contact element 106. The first contact element 106 and the first shield 102 are arranged concentrically, although this is not essential. The first contact element 106 can comprise, for example, copper or another electrically conductive material. Additionally, the first contact element 106 can be plated with silver or tin. By way of example, the first contact element 106 has a circular cross-section. However, this is not essential. The first contact element 106 is designed, by way of example, as a sleeve for the first connection 101. However, the first contact element 106 can also be designed in a different form for the first connection 101, for example as a pin. The first plug connector 100 can also have a different number of first contact elements 106. The second plug connector 200 has a second contact element 206. The second contact element 206 and the second shield 202 are arranged concentrically, although this is not essential. The second contact element 206 can comprise, for example, copper or another electrically conductive material. The second contact element 206 can be plated with tin. The second plug connector 200 can also have a different number of second contact elements 206. The first contact element 106 of the first plug connector 100 is provided to be electrically and mechanically connected to the second contact element 206 of the second plug connector 200. In FIG. 4, the contact elements 106, 206 within the plug connector system 1 are properly connected to each other. In this case, the mark 104 is entirely disposed within the through-opening 204 and the mark 104 can be seen completely.

[0034] In an exemplary embodiment of the plug connector system 1, the through opening 204 is arranged within the area of the contact structure 205 of the second contact element 206, and the contact structure is designed to receive the first contact element 106. This enables inspection during the installation of the second contact element 206 into the second shield 202 of the second plug connector 200. That is, the contact structure 205 of the second contact element 206 must be positioned such that the first contact element 106 can engage within the contact structure 205. For this purpose, the second contact element 206 must be positioned such that the contact structure 205 is at a predetermined distance from the through opening 204. This is effective in that the through opening can be used for inspection purposes. However, the through opening 204 does not necessarily have to be arranged within the area of the contact structure 205.

[0035] To receive the first contact element 106, the contact structure 205 can be designed, for example, as a contact fork. Thereby, since the first contact element 106 can engage between the two fork portions of the contact structure 205 designed as a contact fork, a structure in which the first contact element 106 and the second contact element 206 are arranged orthogonally to each other becomes possible. For this purpose, the first contact element 106 is designed as a pin at the end opposite to the first connection portion 101. However, the contact structure 205 does not necessarily have to be designed as a contact fork. If the first contact element 106 has a different design at the end opposite to the first connection portion 101, the contact structure 205 can similarly have a different design so as to be able to receive the first contact element 106. For example, the first contact element 106 can be designed as a sleeve at the end opposite to the first connection portion 101. In this case, it is convenient for the first contact structure to be designed as a pin.

[0036] The second contact element 206 has a further contact structure 207 on the side of the second contact element 206 that is opposite to the contact structure 205. The further contact structure 207 is designed to receive the inner conductor 208 of the coaxial cable 201. In the plug connector system 1, the inner conductor 208 of the coaxial cable 201 is connected to the second contact element 206 via the further contact structure 207. The coaxial cable 201 further has an outer conductor 209 and an insulator 210. The outer conductor 209 of the coaxial cable 201 abuts against the inner surface 211 of the second shield 202 and is electrically connected to the second shield 202.

[0037] The through-opening 204 in the second shield 202 is disadvantageous because the shielding function of the second shield 202 cannot be fulfilled in the region of the through-opening 204. However, it is advantageous that the portion of the first shield 102 that is disposed within the region of the through-opening 204 is designed to perform a shielding function within the region of the through-opening 204. Accordingly, the electromagnetic field compatibility of the plug connector system 1 can be improved, thereby enabling trouble-free data exchange via the plug connector system 1.

[0038] In an exemplary embodiment of the plug connector system 1, the first contact element 106 and the second contact element 206 are arranged orthogonally to each other, whereby the plug connector system 1 as a whole is designed as a 90° terminal. Also in this case, in the plug connector system 1, the section 107 having the mark 104 of the engagement portion 103 of the first shield 102 is longer than the remaining section 108 of the engagement portion 103 so that no shielding problem occurs in the region of the through-opening 204. Accordingly, the section 107 having the mark 104 projects into the second shield 202 in the first axial direction 10 until the through-opening 204 is covered by a part of the section 107. On the other hand, the remaining section 108 does not project so far into the second shield 202 because it hits the second contact element 206. Therefore, among the engaging portions 103, the section 107 having the mark 104 and the remaining section 108 can each have a semi-cylindrical design or the like, and the section 107 is longer than the remaining sections. In other words, the engaging portion 103 of the first shield 102 has a recess on the side opposite to the position of the mark 104. The recess is provided to receive the second contact element 206 arranged orthogonally to the first contact element 106.

[0039] The first plug connector 100 further has a first dielectric insert 112. The first dielectric insert 112 is arranged within the first shield 102. The first contact element 106 is arranged within the first dielectric insert 112. The second plug connector 200 has a second dielectric insert 212. The second dielectric insert 212 is arranged within the second shield 202. The second contact element 206 is arranged within the second dielectric insert 212. The dielectric inserts 112 and 212 each contain, for example, plastic and can be formed, for example, by a molding process. For example, the dielectric inserts 112 and 212 can each contain polybutylene terephthalate (PBT). In addition, the dielectric inserts 112 and 212 can be reinforced with glass fibers. For example, the dielectric insert can contain 15% glass fiber-reinforced PBT (PBT GF15).

[0040] FIG. 5 schematically shows a further cross-sectional view of the plug connector system 1. In this case, the cross-section includes the first axial direction 10 and extends along a plane designed to extend orthogonally to the second axial direction 20, thereby enabling the viewing of the elements inside the first plug connector 100 in particular. In FIG. 5, the contact structure 205 of the second contact element 206 designed as a contact fork can also be seen. The first contact element 106 reaches between the two fork portions 213 of the contact structure 205, whereby the first contact element 106 and the second contact element 206 are mechanically and electrically connected to each other.

[0041] The engaging portion 103 has openings 109 to enable the first shield 102 and the second shield 202 to be securely mechanically and electrically connected to each other. The receiving portion 203 has contact lamellae 214. The openings 109 are configured to receive the contact lamellae 214. To connect the first shield 102 and the second shield 202 to each other, the contact lamellae 214 can be pressed into the openings 109. The first shield 102 has at least two openings 109 located opposite each other. The second shield 202 has at least two contact lamellae 214 located opposite each other. The exemplary plug connector system 1 has a total of four openings 109 and four contact lamellae 214, with pairs of these located on both sides of each shield 102, 202.

[0042] In the plug connector system 1, the first shield 102 and the second shield 202 are pressed into one another by means of the opening 109 and the contact lamella 214. The shields 102, 202 are therefore properly connected to one another. In this case, the mark 104 is entirely located within the through opening 204, and the mark 104 is therefore fully visible. Therefore, when the opening 109 is located in the area of the contact lamella 214, whereby the first shield 102 and the second shield 202 can be pressed into one another, the mark 104 is fully visible.

[0043] FIG. 6 shows schematically four different exemplary scenarios 11 , 12 , 13 , 14 of the position of the mark 104 relative to the through opening 204 depending on the position of the first shield 102 relative to the first axial direction 10 .

[0044] In the first exemplary scenario 11, the first shield 102 does not engage far enough into the second shield 202 such that the first contact element 106 and the second contact element 206 are reliably mechanically and electrically connected to each other. Additionally, the first shield 102 also does not engage far enough into the second shield 202 such that the opening 109 is not disposed within the region of the contact lamella 214 and as a result cannot be press-fitted together, enabling the first shield 102 to be mechanically and electrically connected to the second shield 202. For this reason, the mark 104 is not entirely disposed within the region of the through-opening 204 and the mark 104 cannot be fully seen. Thus, a proper connection established between the first plug connector 100 and the second plug connector 200 cannot be ensured.

[0045] In the second exemplary scenario 12, the first shield 102 engages deeper into the second shield 202 than in the first scenario 11, specifically such that the mark 104 can be fully seen. Thus, the first contact element 106 and the second contact element 206 can be reliably mechanically and electrically connected to each other. Also, the opening 109 can be disposed within the region of the contact lamella 214, thereby enabling a proper connection to be established between the first plug connector 100 and the second plug connector 200.

[0046] In the third exemplary scenario 13, the first shield 102 engages deeper into the second shield 202 than in the second scenario 12, specifically such that the mark 104 can still be fully seen. Thus, the first contact element 106 and the second contact element 206 can be reliably mechanically and electrically connected to each other. In this case, the opening 109 can likewise be disposed within the region of the contact lamella 214, thereby enabling a proper connection to be established between the first plug connector 100 and the second plug connector 200.

[0047] In a fourth exemplary scenario 14, the first shield 102 is more deeply engaged within the second shield 202 than in the third scenario 13, specifically such that the mark 104 cannot be fully seen. Thus, the first contact element 106 and the second contact element 206 cannot be reliably mechanically and electrically connected to each other. For example, when the first shield 102 is engaged too deeply within the second shield 202, the second contact element 206 may be damaged. Further, as the opening 109 is no longer disposed within the region of the contact lamella 214, the first shield 102 is more deeply engaged within the second shield 202, thereby potentially preventing a proper connection between the first plug connector 100 and the second plug connector 200 from being ensured.

[0048] Figure 7 schematically shows four further different exemplary scenarios 21, 22, 23, 24 of the position of the mark 104 relative to the through-opening 204 in response to rotation of the first shield 102 about the first axial direction 10.

[0049] In a fifth exemplary scenario 21, the first shield 102 is rotating within the second shield 202 such that the opening 109 is not disposed within the region of the contact lamella 214, thereby preventing the first shield 102 and the second shield 202 from being press-fitted together. For this reason, the mark 104 is not entirely disposed within the region of the through-opening 204 and the mark 104 cannot be fully seen. Thus, a proper connection between the first plug connector 100 and the second plug connector 200 cannot be ensured.

[0050] In the sixth exemplary scenario 22, the first shield 102 is rotated within the second shield 202 compared to the fifth scenario 21 such that the opening 109 is disposed within the region of the contact lamella 214, whereby the first shield 102 and the second shield 202 can be press-fitted into each other. For this reason, the mark 104 is entirely disposed within the region of the through-opening 204, and the mark 104 can be fully viewed. Accordingly, an appropriate connection between the first plug connector 100 and the second plug connector 200 can be established.

[0051] In the seventh exemplary scenario 23, the first shield 102 is rotated within the second shield 202 compared to the sixth scenario 22 such that the opening 109 is still disposed within the region of the contact lamella 214, whereby the first shield 102 and the second shield 202 can be press-fitted into each other. The mark 104 is entirely disposed within the region of the through-opening 204, and the mark 104 can be fully viewed. Accordingly, an appropriate connection between the first plug connector 100 and the second plug connector 200 can be established.

[0052] In the eighth exemplary scenario 24, the first shield 102 is rotated within the second shield 202 compared to the seventh scenario 23 such that the opening 109 is no longer disposed within the region of the contact lamella 214, whereby the first shield 102 and the second shield 202 cannot be press-fitted into each other. For this reason, the mark 104 is not entirely disposed within the region of the through-opening 204, and the mark 104 cannot be fully viewed. Accordingly, an appropriate connection between the first plug connector 100 and the second plug connector 200 cannot be ensured.

[0053] In addition to the scenarios 11, 12, 13, 14, 21, 22, 23, 24 shown in FIGS. 6 and 7, other scenarios are also conceivable. In particular, the first shield can be rotated while being moved within the second shield, whereby a wide variety of different scenarios are conceivable.

[0054] Figure 8 schematically shows method steps 31, 32, 33, 34 of a method 30 for forming a plug connector system 1.

[0055] Within the context of the first method step 31, the first shield 102 of the first plug connector 100 with the mark 104 is inserted into the second shield 202 of the second plug connector 200. This can be done manually or automatically by an automated system having corresponding sensors and actuators to enable the implementation of the first method step 31.

[0056] Within the context of the second method step 32, the mark 104 is positioned within the area of the through-opening 204 of the second shield 202, and it is checked whether the mark 104 can be fully seen within this area. Again, this step can be performed manually or automatically. For the mark 104 to be entirely positioned within the through-opening 204 and to automatically check whether the mark 104 can be fully seen, the automated system can have a detection device and an evaluation device. The third method step 33 is also suitable, for example, for the second plug connector 200 to check whether the first plug connector 100 is connected to the device in a defined state. In this case, in particular, it can be checked whether the first plug connector 100 has a defined rotation.

[0057] Within the context of an optional third method step 33, if the mark 104 cannot be fully seen after the checking method step 32, the first plug connector 100 is moved in the first axial direction 10 and / or rotated around the axial direction 10 to position the mark 104 within the area of the through-opening 204 so that the mark 104 can be fully seen. The optional method step can also be performed manually or automatically.

[0058] Within the context of optional fourth method step 34, when the mark 104 is fully visible, the first shield 102 and the second shield 202 are pressed together. For example, an actuator of an automated system can be designed for this purpose. [Explanation of symbols]
