Description

Technology Field

[0001] The present invention relates to plug connectors for a plug connector system, a plug connector system, and a method for manufacturing a plug connector system. Background Technology

[0002] Plug connector systems are known from the prior art. The problem to be solved

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

[0004] A first plug connector for a plug connector system has a first shield having an engaging portion. The engaging portion is provided to engage with a second shield of a second plug connector. An outer side of the engaging portion has a marking. The marking is positioned on the outer side of the first shield in such a way that the marking can be fully aligned with the area of ​​the through opening of the second plug connector, thereby making the marking fully visible.

[0005] During the assembly of the plug connector system, a problem arises in that the first shield of the first plug connector may move and rotate within the second shield of the second plug connector. Consequently, the first plug connector and the second plug connector may be positioned and oriented in a manner where a proper connection between the first plug connector and the second plug connector cannot be guaranteed. To ensure a proper connection, the first plug connector has a marking. During the mating of the first plug connector and the second plug connector, if the marking is fully aligned within the through-opening and becomes fully visible therefrom, the precise position of the first shield of the first plug connector within the second shield of the second plug connector is advantageously indicated.

[0006] In one embodiment, the first plug connector has a first contact element. The first contact element and the first shielding portion are arranged concentrically. The first contact element is provided to be connected to the second contact element of the second plug connector. A marking may be fully visible when the first contact element and the second contact element are mechanically and electrically connected to each other. The marking is advantageously provided to indicate whether the engaging portion is arranged within the receiving portion in such a manner that the first contact element is mechanically and electrically connected to the second contact element.

[0007] In one embodiment, the segment of the interlocking portion having the marking is longer than the remaining segment of the interlocking portion. The segment having the marking is provided to block the through opening of the second shielding portion, thereby improving the electromagnetic compatibility of the plug connector system.

[0008] In one embodiment, the engaging portion has openings provided to receive the contact lamellae of the second plug connector. A marking may be fully visible when the openings are arranged in the zones of the contact lamellae, thereby allowing the first shield and the second shield to be press-fitted together. The marking 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. The shields can be press-fitted together only when the openings are arranged in the zones of the contact lamellae. Thus, the shields are mechanically and electrically connected to each other.

[0009] A second plug connector for a plug connector system has a second shield having a receiving portion. The receiving portion is provided to receive a first shield of the first plug connector. The receiving portion has a through opening. The through opening is positioned in such a way that a marking of the first plug connector can be fully aligned within the area of ​​the through opening, thereby making the marking fully visible. The precise position of the first shield of the first plug connector within the second shield of the second plug connector is advantageously indicated when the marking is fully aligned within the through opening and becomes fully visible therein.

[0010] In one embodiment, the second plug connector has a second contact element. The second contact element and the second shielding portion are arranged concentrically. The second contact element is provided to be connected to the first contact element of the first plug connector. A marking may be fully visible when the first contact element and the second contact element are mechanically and electrically connected to each other. The marking is advantageously 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 designed as a contact fork of the second contact element advantageously enables a configuration in which the first contact element and the second contact element are arranged perpendicularly to each other.

[0012] In one embodiment, a through opening is arranged in the contact structure area of ​​a second contact element, and the contact structure is designed to accommodate a first contact element. The position of the through opening advantageously allows inspection to be performed during the assembly of the second plug connector. In this case, it can be inspected whether the second contact element is positioned in a manner capable of accommodating the first contact element of the first plug connector.

[0013] In one embodiment, the receiving portion has a contact lamellar provided to engage with the openings of the first plug connector. A marking may be fully visible when the contact lamellar is arranged in the zones of the openings, thereby allowing the first shielding portion and the second shielding portion to be pressed together. The marking 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 shielding portion and the second shielding portion.

[0014] A 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 shielding portion of the first plug connector engages with the receiving portion of the second shielding portion of the second plug connector.

[0015] In one embodiment, the engaging portion has openings provided to receive the contact lamella of the second plug connector. The receiving portion has a contact lamella provided to engage with the opening of the first plug connector. The first shielding portion and the second shielding portion are pressed together by the openings and the contact lamella.

[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 shielding part are arranged concentrically. The second contact element and the second shielding part 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 perpendicular to each other.

[0018] A method for manufacturing a plug connector system according to one of the embodiments has the following method steps. A first shielding portion of a first plug connector, provided with a marking, is inserted into a second shielding portion of a second plug connector. It is determined whether the marking is arranged in a through-opening area of ​​the second shielding portion and is fully visible therefrom.

[0019] In one embodiment, the first plug connector is moved axially and / or rotated about the axial direction to position the marking in the through-opening area in such a way that the marking is completely invisible after the verification step.

[0020] In one embodiment, in an additional method step, the first shielding part and the second shielding part are pressed together when the marking becomes fully visible.

[0021] The invention described above is explained in more detail below, along with schematic drawings. Brief explanation of the drawing

[0022] FIG. 1 illustrates a plug connector system in a perspective view. FIG. 2 illustrates a first plug connector and a second plug connector for a plug connector system. FIG. 3 shows the plug connector system of FIG. 1 in a plan view, and a part of the plug connector system in a perspective view and an enlarged view. FIG. 4 is a cross-sectional view illustrating the plug connector system of FIG. 1. FIG. 5 illustrates the plug connector system of FIG. 1 in an additional cross-sectional view. FIG. 6 illustrates four different scenarios for the marking position of the first plug connector for the through opening of the second plug connector according to the position of the first plug connector with respect to the axial direction. FIG. 7 illustrates four additional scenarios for the position of the marking for the through opening according to the rotation of the first plug connector about the axial direction. FIG. 8 illustrates a method for manufacturing a plug connector system. Specific details for implementing the invention

[0023] FIG. 1 schematically illustrates 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, to transmit data.

[0024] A plug connector system (1) has a first plug connector (100) and a second plug connector (200). The first plug connector (100) is designed, for example, as an adapter. For example, a coaxial cable may be connected to a first connection (101) of the first plug connector (100). The coaxial cable connected to the first connection (101) of the first plug connector (100) may be connected in turn to a connection of a printed circuit board or another device, for example. 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) of FIG. 1 may also be omitted. While the first plug connector (100) is provided to accommodate the coaxial cable (201), it is also possible for the second plug connector (200) to be designed as an adapter.

[0025] The first plug connector (100) has a first shielding portion (102). The first shielding portion (102) may comprise, for example, copper or other electrically conductive material. For example, the first shielding portion (102) may be tin-plated, thereby improving the corrosion resistance of the first shielding portion (102). The first shielding portion (102) may also have other coatings that can improve corrosion resistance or other properties. The first shielding portion (102) has an interlocking portion (103). The second plug connector (200) has a second shielding portion (202). The second shielding portion (202) may comprise, for example, stainless steel or other electrically conductive material. The second shielding portion (202) may likewise be tin-plated, for example, or also have other coatings. The second shielding portion (202) has a receiving portion (203). Since the interlocking portion (103) of the first shielding portion (102) of the first plug connector (100) is engaged with the receiving portion (203) of the second shielding portion (202) of the second plug connector (200), the interlocking portion (103) is not visible in FIG. 1.

[0026] For example, the plug connector system (1) of FIG. 1 has an angled design in which the first shielding portion (102) is arranged perpendicularly to a portion of the second shielding portion (202) designed to accommodate a coaxial cable (201). However, this is not mandatory. The plug connector system (1) may also have a different design. For example, the plug connector system (1) may also have a linear design.

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

[0028] During the alignment of the plug connector system (1), a problem arises in that the first shielding portion (102) of the first plug connector (100) may be moved in the first axial direction (10) within the second shielding portion (202) of the second plug connector (200). Additionally, the first shielding portion (102) may be rotated around the first axial direction (10) within the second shielding portion (202). Consequently, 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 guaranteed. In the context of this description, a proper connection refers to a mechanically stable and reliable connection in terms of electrical characteristics.

[0029] To overcome this problem, the interlocking portion (103) of the first shielding portion (102) has a marking (104). The marking (104) is arranged on the outer side (105) of the first shielding portion (102). For example, the marking (104) has a circular design. However, the marking (104) may also have other designs, for example, the marking (104) may be designed in a cross shape. The marking (104) may be manufactured, for example, by a machining process in which the first shielding portion (102) is irradiated with a laser. Alternatively, the marking (104) may also be produced in other ways, for example by a mechanical embossing process, for example by a stamping process. The receiving portion (203) has a through opening (204). For example, the through opening (204) has a circular design. However, the through opening (204) may have a different design, for example, a rectangular design. The through opening (204) may be created in the second shielding part (202), for example, by a boring process or a punching process.

[0030] FIG. 3 schematically illustrates the plug connector system (1) of FIG. 1 in a plan view, and a part of the plug connector system (1) according to the area marked in FIG. 3 in an enlarged perspective view.

[0031] The marking (104) and the through opening (204) are positioned in such a way that the marking (104) can be arranged entirely within the area of ​​the through opening (204), thereby making the marking (104) fully visible. For example, FIG. 3 illustrates a scenario in which the first shielding part (102) engages with the second shielding part (202) in such a way that the marking (104) is arranged, for example, at the center of the through opening (204), thereby making the marking (104) fully visible in this case. Thus, in this case, since the first shielding part (102) engages with the second shielding part (200) in such a way that a mechanically and electrically reliable connection is possible, a proper connection between the first plug connector (100) and the second plug connector (200) can be ensured. The dimensions of the interlocking portion (103) provided to interlock with the second shielding portion (202) and the receiving portion (204) provided to receive the first shielding portion (102) are determined by a combination of the position of the marking (104) on the outer side (105) of the first shielding portion (102) and the position of the through opening (204) in the second shielding portion (204).

[0032] FIG. 4 schematically illustrates the plug connector system of FIG. 1 in a cross-sectional view. In this case, the cross-section extends along a plane spanning the first axial direction (10) and the second axial direction (20), so that the components inside the first plug connector (100) and the second plug connector (200) can be seen in the cross-sectional view.

[0033] The first plug connector (100) has a first contact element (106). The first contact element (106) and the first shielding portion (102) are arranged concentrically, but this is not mandatory. The first contact element (106) may include, for example, copper or other conductive material. The first contact element (106) may additionally be silver-plated or tin-plated. For example, the first contact element (106) has a circular cross-section. However, this is not mandatory. The first contact element (106) is designed as a sleeve in the first connection portion (101), for example. However, the first contact element (106) may also be designed differently in the first connection portion (101), for example, as a pin. The first plug connector (100) may 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 (203) are arranged concentrically, though this is not mandatory. The second contact element (206) may include, for example, copper or other electrically conductive material. The second contact element (206) may be tin-plated. The second plug connector (200) may 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) of the plug connector system (1) are appropriately connected to each other. In this case, the marking (104) may be fully arranged and fully visible within the through opening (204).

[0034] In an exemplary embodiment of the plug connector system (1), a through opening (204) is arranged in a section of the contact structure (205) of the second contact element (206), and the contact structure is designed to accommodate the first contact element (106). This enables inspection while installing the second contact element (206) within the second shielding section (202) of the second plug connector (200). The contact structure (205) of the second contact element (206) must be positioned in such a way that the first contact element (106) can engage with the contact structure (205). To this end, 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 possible in that the through opening can be used for inspection purposes. However, the through opening (204) does not necessarily have to be arranged in a section of the contact structure (205).

[0035] To accommodate the first contact element (106), the contact structure (205) may be designed, for example, as a contact fork. This enables a configuration in which the first contact element (106) and the second contact element (206) are arranged perpendicularly to each other, because the first contact element (106) can be engaged between the two fork portions of the contact structure (205) designed as a contact fork. To this end, the first contact element (106) is designed as a pin at the opposite end of the first connection (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 opposite end of the first connection (101), the contact structure (205) may likewise have a different design to accommodate the first contact element (106). For example, the first contact element (106) may be designed as a sleeve at the opposite end of the first connection part (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 an additional contact structure (207) on the side of the second contact element (206) opposite the contact structure (205). The additional contact structure (207) is designed to accommodate an internal conductor (208) of the coaxial cable (201). In the plug connector system (1), the internal conductor (208) of the coaxial cable (201) is connected to the second contact element (206) through the additional contact structure (207). The coaxial cable (201) also has an external conductor (209) and an insulator (210). The external conductor (209) of the coaxial cable (201) contacts the internal side (211) of the second shield (202) and is electrically connected to the second shield (202).

[0037] The through-opening (204) of the second shielding part (202) is disadvantageous in that the shielding function of the second shielding part (202) cannot be achieved in the area of ​​the through-opening (204). However, a part of the first shielding part (102) arranged in the area of ​​the through-opening (204) is advantageously designed to perform a shielding function in the area of ​​the through-opening (204). Thus, the electromagnetic compatibility of the plug connector system (1) can be improved, thereby allowing data exchange to be performed without problems through 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 perpendicularly to each other, thereby designing the entire plug connector system (1) as a 90° terminal. In order to prevent the shielding problem in the area of ​​the through opening (204) from occurring in this case as well, in the plug connector system (1), the segment (107) of the engaging portion (103) of the first shielding portion (102) having the marking (104) is longer than the remaining segment (108) of the engaging portion (103). Thus, the segment (107) having the marking (104) protrudes into the first axial direction (10) and the second shielding portion (202) to the extent that the through opening (204) is covered by a part of the segment (107). On the other hand, the remaining segment (108) does not protrude so far into the second shielding portion (202) because it will come into contact with the second contact element (206). Accordingly, the segment (107) of the interlocking portion (103) having the marking (104) and the remaining segment (108) may each have a semi-cylindrical design, and the segment (107) is longer than the remaining segment. In other words, the interlocking portion (103) of the first shielding portion (102) has a recess on the opposite side of the marking (104). The recess is provided to accommodate the second contact element (206) arranged perpendicularly to the first contact element (106).

[0039] The first plug connector (100) also has a first dielectric insert (112). The first dielectric insert (112) is arranged within the first shielding portion (102). A 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 shielding portion (202). A second contact element (206) is arranged within the second dielectric insert (212). Each of the dielectric inserts (112, 212) may comprise, for example, plastic and may be manufactured, for example, by a molding process. For example, each of the dielectric inserts (112, 212) may comprise polybutylene terephthalate (PBT). The dielectric inserts (112, 212) may additionally be reinforced with glass fibers. For example, genome inserts may contain 15% glass fiber reinforced PBT (PBT GF 15).

[0040] FIG. 5 schematically illustrates an additional cross-sectional view of a plug connector system (1). In this case, the cross-section extends along a plane designed to include the first axial direction (10) and extend perpendicularly to the second axial direction (20), thereby allowing the elements inside the first plug connector (100) to be seen, in particular. A contact structure (205) designed as a contact fork of a second contact element (206) can also be seen in FIG. 5. The first contact element (106) reaches between the two fork portions (213) of the contact structure (205), thereby mechanically and electrically connecting the first contact element (106) and the second contact element (206) to each other.

[0041] Additionally, in order to ensure that the first shielding portion (102) and the second shielding portion (202) can be reliably mechanically and electrically connected to each other, the interlocking portion (103) has openings (109). The receiving portion (203) has contact lamellas (214). The openings (109) are provided to receive the contact lamellas (214). To connect the first shielding portion (102) and the second shielding portion (202) to each other, the contact lamellas (214) can be compressed into the openings (109). The first shielding portion (102) has at least two mutually opposing openings (109). The second shielding portion (202) has at least two mutually opposing contact lamellas (214). An exemplary plug connector system (1) has a total of four openings (109) and four contact lamellas (214), of which pairs are arranged on opposite sides of individual shielding parts (102, 202).

[0042] In the plug connector system (1), the first shielding portion (102) and the second shielding portion (202) are pressed into each other by the openings (109) and the contact lamella (214). Thus, the shielding portions (102, 202) are properly connected to each other. In this case, the marking (104) can be fully arranged within the through opening (204) and become fully visible. Thus, the marking (104) can be fully visible when the openings (109) are arranged in the zones of the contact lamella (214), thereby allowing the first shielding portion (102) and the second shielding portion (202) to be pressed into each other.

[0043] FIG. 6 schematically illustrates four different exemplary scenarios (11, 12, 13, 14) regarding the position of the marking (104) for the through opening (204) according to the position of the first shielding part (102) with respect to the first axial direction (10).

[0044] In the first exemplary scenario (11), the first shield (102) is not engaged sufficiently far from the second shield (202) so that the first contact element (106) and the second contact element (206) can be mechanically and electrically connected to each other in a reliable manner. Furthermore, the first shield (102) may also not be engaged sufficiently far from the second shield (202) so that the first shield (102) can be mechanically and electrically connected to the second shield (202), because the openings (109) are not arranged in the area of ​​the contact lamella (214), and as a result, they cannot be pressed into each other. For this reason, the marking (104) is not fully arranged in the area of ​​the through opening (204) and is not fully visible. Therefore, a proper connection established between the first plug connector (100) and the second plug connector (200) cannot be guaranteed.

[0045] In the second exemplary scenario (12), the first shielding portion (102) engages more deeply with the second shielding portion (202) than in the first scenario (11), particularly in such a way that the marking (104) is fully visible. Thus, the first contact element (106) and the second contact element (206) can be mechanically and electrically connected to each other in a reliable manner. Additionally, it is possible for the openings (109) to be arranged in the area of ​​the contact lamella (214), thereby establishing a proper connection between the first plug connector (100) and the second plug connector (200).

[0046] In the third exemplary scenario (13), the first shield (102) engages more deeply with the second shield (202) than in the second scenario (12), particularly in such a way that the marking (104) is still fully visible. Thus, the first contact element (106) and the second contact element (206) can be mechanically and electrically connected to each other in a reliable manner. In this case, the openings (109) can likewise be arranged in the area of ​​the contact lamella (214), thereby establishing a proper connection between the first plug connector (100) and the second plug connector (200).

[0047] In the fourth exemplary scenario (14), the first shield (102) engages more deeply with the second shield (202) than in the third scenario (13), particularly in such a way that the marking (104) is no longer completely visible. Consequently, the first contact element (106) and the second contact element (206) can no longer be mechanically and electrically connected to each other in a reliable manner. For example, when the first shield (102) engages too deeply with the second shield (202), the second contact element (202) may be damaged. Additionally, when the first shield (102) engages too deeply with the second shield (202), the openings (109) are no longer arranged in the area of ​​the contact lamella (214), and thus, a proper connection between the first plug connector (100) and the second plug connector (200) cannot be guaranteed.

[0048] FIG. 7 schematically illustrates four different exemplary scenarios (21, 22, 23, 24) regarding the position of the marking (104) for the through opening (204) according to the rotation of the first shielding part (102) with respect to the first axial direction (10).

[0049] In the fifth exemplary scenario (21), the first shield (102) is rotated within the second shield (202) in such a way that the openings (109) are not arranged in the area of ​​the contact lamella (214), and thus the first shield (102) and the second shield (202) cannot be pressed into each other. For this reason, the marking (104) is not fully arranged in the area of ​​the through opening (204) and is not fully visible. Therefore, a proper connection between the first plug connector (100) and the second plug connector (200) cannot be guaranteed.

[0050] In the sixth exemplary scenario (22), in relation to the fifth scenario (21), the first shield (102) is rotated within the second shield (202) in such a way that the openings (109) are arranged in the area of ​​the contact lamella (214), thereby allowing the first shield (102) and the second shield (202) to be pressed together. For this reason, the marking (104) is fully arranged in the area of ​​the through opening (204) and becomes fully visible. Thus, a proper connection between the first plug connector (100) and the second plug connector (200) can be established.

[0051] In the seventh exemplary scenario (23), in relation to the sixth scenario (22), the first shield (102) is rotated within the second shield (202) in such a way that the openings (109) are still arranged in the area of ​​the contact lamella (214), thereby allowing the first shield (102) and the second shield (202) to be pressed together. The marking (104) is fully arranged in the area of ​​the through opening (204) and becomes fully visible. Thus, a proper connection between the first plug connector (100) and the second plug connector (200) can be established.

[0052] In the eighth exemplary scenario (24), in relation to the seventh scenario (23), the first shield (102) is rotated within the second shield (202) in such a way that the openings (109) are no longer arranged in the area of ​​the contact lamella (214), and thus the first shield (102) and the second shield (202) cannot be pressed into each other. For this reason, the marking (104) is not fully arranged in the area of ​​the through opening (204) and is not fully visible. Therefore, a proper connection between the first plug connector (100) and the second plug connector (200) cannot be guaranteed.

[0053] In addition to the scenarios (11, 12, 13, 14, 21, 22, 23, 24) illustrated in FIGS. 6 and 7, other scenarios may also be considered. In particular, the first shielding part may be moved within the second shielding part and rotated simultaneously, thereby allowing a wide variety of scenarios to be considered.

[0054] FIG. 8 schematically illustrates the method steps (31, 32, 33, 34) of the method (30) for manufacturing a plug connector system (1).

[0055] In the context of the first method step (31), the first shielding portion (102) of the first plug connector (100) provided with the marking (104) is inserted into the second shielding portion (202) of the second plug connector (200). This can be done manually or automatically by an automated system having corresponding sensors and actuators so that the first method step (31) can be executed.

[0056] In the context of the second method step (32), it is determined whether the marking (104) is aligned in the area of ​​the through opening (204) of the second shielding part (202) and is fully visible therein. Again, this step can occur manually or automatically. To automatically determine whether the marking (104) is fully aligned and fully visible within the through opening (204), the automation system may have a detection device and an evaluation device. The third method step (33) is also suitable for determining, for example, by the second plug connector (200), whether the first plug connector (100) is connected to the device in a prescribed manner. In this case, in particular, it can be determined whether the first plug connector (100) has a prescribed rotation.

[0057] In the context of the optional third method step (33), the first plug connector (100) is moved in the first axial direction (10) and / or rotated around the axial direction (10) to position the marking (104) in the area of ​​the through opening (204) such that the marking (104) becomes fully visible if the marking (104) is not fully visible after the verification method step (32). Additionally, the optional method step can be performed manually or automatically.

[0058] In the context of the optional fourth method step (34), when the marking (104) becomes fully visible, the first shielding part (102) and the second shielding part (202) are pressed together. For example, an actuator of an automation system may be designed for this purpose. Explanation of the symbols
