Description

Technical Field

[0001] This invention relates to a shielded spring contact, a plug-in connector including a shielded spring contact, and a plug-in connector system including a shielded spring contact. Background Technology

[0002] Prior art knows of plug-in connector systems with shielding systems configured to allow shielding current flow. When a high-frequency current flows through an electrical conductor, the shielding current can be capacitively or inductively coupled into the shield. If the first plug-in connector of the plug-in connector system is integrated into, for example, a conductive housing of an assembly, the shielding current can be conducted to the housing wall.

[0003] For this purpose, the housing wall typically has a hollow cylindrical cap, which is arranged in the area surrounding the cutout in the housing wall. This cap on the housing wall can be manufactured using a die-casting process. The cap is designed to shield the electrical conductors arranged in the cutout and to divert shielding current.

[0004] In addition to the complex manufacturing of the housing, the cap may also need to be treated to ensure a secure electrical contact between the cap and the shielding structure of the second insertion connector. Summary of the Invention

[0005] The object of the present invention is to provide a shielded spring contact for a plug-in connector and a plug-in connector system, as well as a plug-in connector and a plug-in connector system, each comprising a shielded spring contact having the features of its respective independent claim. This object is achieved by shielded spring contacts, plug-in connectors, and plug-in connector systems having the features of the independent claims. Advantageous developments are specified in the dependent claims.

[0006] A plug-in connector system includes a first plug-in connector and a second plug-in connector. The first plug-in connector has a component housing portion and a shielded spring contact connected to the component housing portion. The second plug-in connector has a shielded housing connected to the shielded spring contact. The component housing portion has a bottom side and a first channel opening. The shielded spring contact has a flat base portion and a shielding portion. The base portion has a top side and a cutout. The shielding portion of the shielded spring contact also has a wall connected to the base portion and surrounding the cutout. This wall has an outer side, an inner side, an upper side, and a lower side. The wall is disposed on the top side of the base portion via its lower side such that the lower side of the wall laterally surrounds the cutout in the base portion. The shielding housing of the second plug-in connector has a shielding housing wall having a second channel opening facing the component housing portion. The shielded spring contact is supported against the bottom side of the component housing portion by the top side of the base portion. The shielding portion of the shielded spring contact protrudes through the first channel opening in the component housing portion. The shielding portion also protrudes into the shielding housing through a second channel opening in the shielding housing wall, and is supported against the shielding housing wall in the area of ​​the second channel opening.

[0007] The shielded spring contact advantageously enables simplified manufacturing of the component housing portion, eliminating the need for a capped component housing portion. Furthermore, no subsequent machining of the capped component housing portion is required, resulting in simpler manufacturing of the component housing portion, the first insertion connector, and the insertion connector system. Therefore, the insertion connector system is based on a component housing portion that lacks a cap, instead utilizing a shielded spring contact that protrudes through a channel opening in the component housing portion and is electrically and mechanically connected to it.

[0008] In one embodiment, the wall of the shielding spring contact is at least partially tapered and tapers away from the base portion. In this way, a wedge effect can be advantageously generated in the plug-in connector system, resulting in improved electrical and mechanical contact between the shielding spring contact and the shielding housing of the second plug-in connector.

[0009] In one embodiment, the metal coating is at least partially disposed on the outer side of the wall. The metal coating can advantageously improve the electrical contact between the shielded spring contact and the shielding housing of the second insertion connector. The metal coating can be disposed on the outer side of the wall by, for example, an electrochemical process. Alternatively, the metal coating can be disposed by roll coating.

[0010] In one embodiment, the shielding portion widens at least partially in the region between the upper and lower sides. This widened wall can advantageously improve the electrical and mechanical contact between the shielding spring contact and the shielding housing of the second insertion connector.

[0011] In one embodiment, a metal coating is disposed in the area of ​​the widened portion. The metal coating disposed in the widened portion can advantageously improve the electrical contact between the shielded spring contact and the shielding housing of the second insertion connector.

[0012] In one embodiment, the fixing structure is arranged in the areas on the upper and lower sides of the outer side of the wall. The fixing structure advantageously makes it possible for the shielded spring contact to wed into the component housing portion, resulting in a particularly secure mechanical and electrical connection between the shielded spring contact and the component housing portion.

[0013] In one embodiment, the wall is at least partially slotted along a direction perpendicular to the base portion.

[0014] In one embodiment, the base portion is an annular disc-shaped construction, or comprises multiple annular disc segments. For this purpose, the base portion is designed to support the abutment portion of the component housing, resulting in the establishment of reliable electrical contact between the shielding spring contact and the component housing portion.

[0015] The first insert connector has a component housing portion and a shielding spring contact connected to the component housing portion. The component housing portion has a bottom side and a first channel opening. The shielding spring contact has a flat base portion and a shielding portion. The base portion has a top side and a cutout. The shielding portion of the shielding spring contact has a wall connected to the base portion and surrounding the cutout. This wall has an outer side, an inner side, an upper side, and a lower side. The wall is arranged on the top side of the base portion via its lower side, such that the lower side of the wall laterally surrounds the cutout in the base portion. The shielding spring contact is supported against the bottom side of the component housing portion by the top side of the base portion. The shielding portion of the shielding spring contact protrudes through the first channel opening in the component housing portion. The shielding portion is configured to protrude through a second channel opening in the shielding housing wall into the shielding housing of the second insert connector of the insert connector system according to one of the foregoing embodiments, and is supported against the shielding housing wall in the region of the second channel opening.

[0016] A shielded spring contact has a flat base portion and a shielding portion. The base portion has a top side and a cutout. The shielding portion has a wall connected to the base portion and surrounding the cutout. The wall has an outer side, an inner side, an upper side, and a lower side. The wall is disposed on the top side of the base portion via its lower side such that the lower side of the wall laterally surrounds the cutout in the base portion. The base portion is configured to support abutment against the bottom side of an assembly housing portion of a first insert connector via its top side. The shielding portion is configured to protrude through a first channel opening in the assembly housing portion of the first insert connector. The shielding portion is configured to protrude through a second channel opening in the shielding housing wall into the shielding housing of a second insert connector of an insert connector system according to one embodiment, and to support abutment against the shielding housing wall in the region of the second channel opening.

[0017] The shielded spring contact may include features described in conjunction with various embodiments of the insert connector system itself, whether it is part of the insert connector system or part of the first insert connector. Attached Figure Description

[0018] The invention will now be explained in more detail with reference to the accompanying drawings, in which:

[0019] Figure 1 A cross-sectional view through the plug-in connector system is shown.

[0020] Figure 2 It shows crossing Figure 1 A perspective cross-sectional view of the shielding system of a plug-in connector system.

[0021] Figure 3 It shows Figure 2 A perspective view of the shielding spring contact component of the shielding system.

[0022] Figure 4 A perspective view of a shielding spring contact element according to another embodiment is shown.

[0023] Figure 5 A cross-sectional view is shown through a plug-in connector system according to the prior art. Detailed Implementation

[0024] Figure 1 A schematic cross-sectional view through the plug-in connector system 10 is shown. The plug-in connector system 10 can be configured, for example, as a high-voltage plug-in connection, and can be, for example, a component of a motor vehicle, such as an electric vehicle or a hybrid vehicle, but this is not absolutely necessary.

[0025] The plug-in connector system 10 has a first plug-in connector 100 and a second plug-in connector 200, which are inserted together into the plug-in connector system 10. The first plug-in connector 100 is configured as a receptacle. The second plug-in connector 200 is configured as a plug. The second plug-in connector 200 is exemplary of an angled configuration, resulting in the plug-in connector system 10 also being angled. However, the second plug-in connector 200 can also be a straight configuration. The plug-in connector system 10 can have any desired number of poles. Therefore, Figure 1 The view shown in the figure is a cross-sectional view through one pole of the plug-in connector system 10.

[0026] The second plug-in connector 200 has a second electrical conductor 201. The second electrical conductor 201 can contain any desired metal, such as copper. The second electrical conductor 201 can be configured as a single stranded wire, or contain, for example, a large number of stranded wires that can be twisted together. The second electrical conductor 201 is embedded in a first insulator 202. The first insulator 202 contains a dielectric plastic. A shield 203 is disposed on the first insulator 202. The shield 203 contains a metal, such as tin-plated copper, and is designed to shield the second electrical conductor 201. The shield 203 can be configured, for example, as a shielding braid. The second electrical conductor 201 and the shield 203 are arranged concentrically. (The last sentence appears to be incomplete and possibly refers to a diagram or diagram, but without further context, it's unclear what it refers to.) Figure 1 In the plane extending from the cross-section, the second conductor 201 has a circular cross-section, and the shield 203 has an annular cross-section. However, the second conductor 201 and the shield 203 can also be designed with different shapes. A second insulator 204, also comprising dielectric plastic, is disposed on the shield 203. The first and second insulators 202 and 204 can comprise, for example, polyvinyl chloride (PVC), polyethylene (PE), rubber, or polyurethane (PUR). The second conductor 201, the first insulator 202, the shield 203, and the second insulator 204 form the cable 205.

[0027] The second insertion connector 200 has a second contact structure 207. The second contact structure 207 comprises metal. The second contact structure 207 has a connection portion 208 that is electrically and mechanically connected to a second electrical conductor 201. The second contact structure 207 also has a contact portion 209 that is electrically and mechanically connected to the connection portion 208, wherein portions 208 and 209 of the second contact structure 207 can be integrally connected to each other; that is, the second contact structure 207 can be constructed as a single unit, but this is not necessary. The contact portion 209 is exemplarily constructed as a contact sleeve. However, the contact portion 209 can also be configured as a contact pin.

[0028] The second plug-in connector 200 has a housing 210. A cable 205 protrudes into the housing 210. The housing 210 may be made of, for example, plastic. The second plug-in connector 200 also has a shielding housing 206, which is made of metal, such as a copper alloy, brass, or steel. The shielding housing 206 is disposed within the housing 210. The shielding housing 206 is electrically and mechanically connected to the shielding member 203. The cable 205 protrudes into the housing 210 through a first opening 214 in the housing 210. A second seal 211 is disposed in the region of the first opening 214 and seals the region between the housing 210 and the cable 205. A second electrical conductor 201 of the cable 205 protrudes into the shielding housing 206 through a second opening 215 in the shielding housing 206. A second contact structure 207 is disposed in the shielding housing.

[0029] The first insert connector 100 has a component housing portion 101 and a shielding spring contact 102. The shielding spring contact 102 is electrically connected to the component housing portion 101. In the insert connector system 10, the shielding spring contact 102 is electrically connected to a shielding housing 206. The component housing portion 101 and the shielding spring contact 102 of the first insert connector 100, together with the shielding housing 206 and the shielding member 203 of the second insert connector 200, form the shielding system 11 of the insert connector system 10. Figure 2 Schematic illustration of crossing Figure 1 A perspective cross-sectional view of the shielding system 11 of the plug-in connector system 10. For clarity, Figure 2 Other components of the plug-in connector system 10 and the shield 203 of the shielding system 11 are not shown.

[0030] The component housing portion 101 has a first top side 110 and a first bottom side 111 opposite to the first top side 110. Furthermore, the component housing portion 101 has a first channel opening 112. The shielding spring contact 102 has a flat base portion 114 and a shielding portion 113. The flat base portion 114 has a second top side 115, a bottom side 116 opposite to the second top side 115, and a cutout 122. The shielding spring contact 102 is supported against the first bottom side 111 of the component housing portion 101 via the second top side 115 of the base portion 114, and is electrically connected to the component housing portion 101 in this manner.

[0031] The shielding portion 113 of the shielded spring contact 102 has a wall 117 that connects to the base portion 114 and surrounds the cutout 122. The wall 117 has an outer side 119, an inner side 118, an upper side 120, and a lower side 121. The wall 117 is disposed on a second top side 115 of the base portion 114 via its lower side 121, such that the lower side 121 of the wall 117 laterally surrounds the cutout 122 in the base portion 114. The shielding portion 113 of the shielded spring contact 102 protrudes through a first channel opening 112 in the assembly housing portion 101. In the region of the first channel opening 112, the shielding portion 113 is supported against the assembly housing portion 101 by the outer side 119 of its wall 117.

[0032] The shielding housing 206 of the second plug-in connector 200 has a shielding housing wall 212 having a second channel opening 213 facing the component housing portion 101. In the shielding system 11 of the plug-in connector system 10, the shielding portion 113 protrudes into the shielding housing 206 through the second channel opening 213 in the shielding housing wall 212, and in the region of the second channel opening 213, it is supported against the shielding housing wall 212 by the outer side 119 of its wall 117, resulting in the shielding portion 113 being electrically connected to the shielding housing 206. In this case, the wall 117 is configured to extend obliquely relative to the shielding housing wall 212.

[0033] The following reference Figure 1 Explain the insert connector system 10. A first insert connector 100 has a head 131. The head 131 comprises, for example, at least one type of plastic. The head 131 has a portion that supports both a first bottom side 111 abutting against a component housing portion 101 and a second bottom side 116 abutting against a base portion 114 of a shielding spring contact 102. Furthermore, the head 131 has a portion 103 that extends through a first channel opening 112 in the component housing portion 101 and supports an inner side 118 abutting against a wall 117 of a shielding portion 113. The portion 103 of the head 131 protruding through the first channel opening 112 exemplarily protrudes beyond... Figure 1 The wall 117 of the shielding part 113 shown in the figure.

[0034] The first insert connector 100 has a first contact structure 104. The first contact structure 104 comprises metal and is configured as a double sleeve only by way of example. The first contact structure 104 of the first insert connector 100 protrudes through a first channel opening 112 in the component housing portion 101. In the insert connector system 10, the first contact structure 104 protrudes into the shielding housing 206 of the second insert connector 200. The first contact structure 104 abuts against the inner side of a portion 103 of the head 131 by an outer support.

[0035] The first contact structure 104 is electrically and mechanically connected to the second contact structure 207 in the plug-in connector system 10. Figure 1 In an exemplary embodiment of the plug-in connector system 10, a second contact structure 207 of the second plug-in connector 200, configured as a contact sleeve, protrudes at one end into a first contact structure 104 of the first plug-in connector 100, configured as a double sleeve. In this way, the first contact structure 104 is electrically connected to a second electrical conductor 201 of the second plug-in connector 200.

[0036] For the purpose of securing the first contact structure 104, the head 131 has another portion 106 that also protrudes through the first channel opening 112 in the component housing portion 101. This other portion 106 protrudes through the first contact structure 104 and supports against the inside of the first contact structure 104. In this way, the first contact structure 104 is secured within the first insert connector 100. For example, the other portion 106 also protrudes into the second contact structure 207, which is configured as a sleeve. In this way, the connection including the first contact structure 104 and the second contact structure 207 is secured and stabilized.

[0037] The first insert connector 100 may have a first electrical conductor, which is electrically and mechanically connected to the first contact structure 104. For simplicity, Figure 1 The first electrical conductor is not shown. The first electrical conductor may be arranged on the side of the first contact structure 104 away from the second contact structure 207. In this way, the first electrical conductor 105, the first contact structure 104, the second contact structure 207, and the second electrical conductor 201 are electrically connected to each other in the plug-in connector system 10.

[0038] The head 131 has an attachment 107 disposed above the component housing portion 101. A seal 109 is disposed in the region surrounding the shielding spring contact 102. The seal 109 is configured to seal the region between the housing 210 of the second insert connector 200 and the attachment 107 of the first insert connector 100. Furthermore, the attachment 107 may also have a structure for receiving and securing the housing 210 of the second insert connector 200. In this way, the first insert connector 100 and the second insert connector 200 are securely connected to each other.

[0039] The first insert connector 100 can, for example, be integrated into the component housing of an electrical component, wherein the component housing portion 101 is part of the wall of the component housing. However, the first insert connector 100 can also, for example, be configured as a connector strip that can be fitted to the component housing. In this case, the first insert connector 100 can be secured to the wall of the component housing via the component housing portion 101. In both cases, shielding current can flow through the component housing portion 101 to the component housing.

[0040] The shielding system 11 of the plug-in connector system 10 is configured to electromagnetically shield the first conductor 105, the first contact structure 104, and the second contact structure 207. The second conductor 201 is shielded by the shield 203 of the cable 205. The shielding spring contact 102 of the first plug-in connector 100 is designed to shield the transition area between the component housing portion 101 of the first plug-in connector 100 and the shielding housing 206 of the second plug-in connector. In this case, the wall 117 of the shielding portion 113 of the shielding spring contact 102 is configured to shield the first contact structure 104 in the area between the component housing portion 101 and the shielding housing 206.

[0041] If a voltage is applied to the system comprising the first conductor 105, the first contact structure 104, the second contact structure 207, and the second conductor 201, the shielding current can be capacitively and / or inductively coupled to the walls 117 of the shield 203, the shield housing 206, and the shielding spring contact 102. The shielding current can advantageously flow through the walls 117 of the shielding spring contact 102 and through its base portion 114 to the assembly housing portion 101, resulting in the avoidance of interference effects from the shielding current.

[0042] Figure 3 The first insert connector 100 and are schematically shown. Figure 1 A perspective view of the shielded spring contact 102 of the plug-in connector system 10. The shielded spring contact 102 can be manufactured from a sheet metal, for example, by a deep drawing process.

[0043] For example, the base portion 114 has an annular disc-shaped configuration. Alternatively, the base portion 114 may also include multiple annular disc segments securely connected to the wall 117. The shielding spring contact 102 has at least a partially tapered or hollow truncated cone-shaped configuration. In this case, the wall 117 tapers away from the base portion 114. The at least partially tapered shielding spring contact 102 has the advantage of inducing a wedging effect in the first insertion connector 100 and respectively in the insertion connector system 10, resulting in reliable electrical connection of the shielding spring contact to the component housing portion 101 and the shielding housing wall 212 of the shielding housing 206. However, the wall 117 of the shielding spring contact 102 does not necessarily have to be partially tapered. For example, the shielding spring contact 102 may also be entirely hollow cylindrical.

[0044] The fixing structure 124 is arranged in the areas of the outer side 119 and the lower side 121 of the wall. Figure 3 In this embodiment, the fixing structure 124 is exemplary implemented as teeth 125. In this case, a plurality of teeth are arranged on the outer side 119 of the wall 117, in the region of the lower side 121, and surrounding the wall 117. In the first insertion connector 100 and respectively in the insertion connector system 10, the teeth 125 reliably connect the shielding spring contact 102 and the component housing portion 101 to each other, because the teeth 125 are configured to wed into the component housing portion 101 in the region of the first channel opening 112. However, the fixing structure 124 does not necessarily have to be implemented as teeth 125. The fixing structure 124 can also be omitted entirely.

[0045] according to Figure 3 The wall 117 of the shielded spring contact has a slotted structure at least partially extending in a direction perpendicular to the base portion 114. As a result, the wall 117 has at least partially a web 123, which extends in a direction perpendicular to the base portion 114 and is arranged around the wall 117. Consequently, the shielded spring contact 102 can have a more flexible and resilient structure. The web 123 in the wall 117 can be manufactured, for example, by a stamping process. However, the wall 117 does not necessarily have to be slotted.

[0046] Figure 4 A perspective view of a shielding spring contact 102 according to another embodiment is shown schematically. Figure 4 The shielded spring contact 102 represents an alternative embodiment of the first insert connector 100 and the first insert connector system 10. Figure 3 and Figure 4The shielded spring contact 102 has similarities. Similar and identical elements in the shielded spring contact 102 are provided with the same reference numerals. In the following description, only the differences between the shielded spring contact 102 and the shielded spring contact 102 will be explained. Despite the differences, Figure 3 The description of the shielded spring contact 102 also applies to Figure 4 The shielded spring contact 102.

[0047] Figure 4 The shielding spring contact 102 has a hollow cylindrical structure, rather than a conical structure. Figure 4 The shielding spring contact 102 also has a fixing structure 124. However, the fixing structure 124 is not configured as teeth 125, but has fins 126 arranged on the outer side 119 of the wall 117 and protruding obliquely away from the wall 117.

[0048] and Figure 3 Compared to the shielded spring contact 102, Figure 4 The shielding spring contact 102 does not have a base portion 114 with an annular disc structure, but has a base portion 114 including an annular disc section 127 connected to the wall 117. Figure 4 The shielding spring contact 102 can be manufactured, for example, by a combination of stamping and forming processes. After the metal is stamped, it can be formed, for example, by a cylindrical or conical drum, thereby creating a surrounding wall 117.

[0049] The stamping process may also include stamping fins 126. The fins 126 can then be reformed in such a way that they project obliquely outward from the wall 117. The stamping process may also include stamping a web 123. Figure 4 In an exemplary embodiment, in addition to the web 123, the shielding spring contact 102 also has an additional web 130, which can also be manufactured by stamping. The additional web 130 is firmly connected to the wall 117 only on the side facing the upper side 120 of the wall 117. Conversely, the additional web 130 is not connected to the wall 117 on the side facing the lower side 121. However, the web 123 and the additional web 130 can also be omitted.

[0050] Figure 4 The shielding spring contact 102 has a bent portion 128 in the region between the upper side 120 and the lower side 121. The shielding spring contact 113 therefore has at least a widened construction in the region between the upper side 120 and the lower side 121, and has an increased diameter in that region. Figure 2The shielding spring contact 102 may also have such a bent portion 128. By way of example only, the bent portion 128 is of a circumferential construction. The bent portion 128 allows for improved electrical and mechanical contact between the shielding portion 113 and the shielding housing 206. The bent portion 128 may also be omitted.

[0051] Figure 4 The shielding portion 133 of the shielded spring contact 102 includes a metal coating 129. The metal coating 129 is at least partially disposed on the outer side 119 of the wall 117. For example, the metal coating 129 is disposed in the region of the web 123 and the region of the bend 128, which is not strictly necessary. For example, the metal coating 129 may also be disposed on another web 130 and / or on the outside of the web 123 or on the outer side 119 of the wall 117 of another web 130. The metal coating 129 may contain, for example, silver or gold or other metals and is intended to further improve the electrical and mechanical contact between the shielding portion 113 and the shielding housing 206. Figure 3 The shielded spring contact 102 may also have a metal coating 129, which may also be arranged in the region of the curved portion 128 or in another region on the outer side 119 of the wall 117. The metal coating 129 may also be omitted.

[0052] Figure 5 A schematic cross-sectional view through a known insert connector system 1 according to the prior art is shown. The known insert connector system 1 is related to... Figure 1 The plug-in connector system 10 is similar. Similar components are provided with the same reference numerals.

[0053] and Figure 1 Compared to the known insert connector system 10, the known insert connector system 1 does not have a shielded spring contact 102. Instead, the insert connector system 1 has a cap 2. The cap 2 and the component housing portion 101 are individually connected to each other in the known insert connector system 1. The cap 2 is a hollow cylindrical construction, arranged on a first top side 110 of the component housing portion 101 and laterally surrounding a first channel opening 112 in the component housing portion 101. The cap 2 is electrically and mechanically connected to the shielding housing 206 of the second insert connector 200.

[0054] Because the component housing portion 101 and the cap 2 are constructed as a single piece, the method for manufacturing the component housing portion 101 is relatively complex. Furthermore, it is possible that the cap 2 requires additional processing to ensure electrical contact with the shielding housing 206. In contrast, the shielding spring contact 102 enables the relatively simple manufacture of the component housing portion 101, and thus also enables the relatively simple manufacture of the first insertion connector 100 and the insertion connector system 10. Moreover, the extremely broad embodiments of the shielding spring contact 102 explained above can have a series of further advantageous technical effects.

[0055] Therefore, according to Figure 1 The concept of the plug-in connector system 10 is basically based on Figure 2 The shielding system 11 is provided, wherein the shielding system 11 has according to Figure 3 or Figure 4 The shielding spring contact 102 is inserted into the assembly housing portion 101. For this reason, the plug-in connector system 10 and the first plug-in connector 100 should be understood as follows: elements of the first plug-in connector 100 and the plug-in connector system 10 not included in the shielding system 11 can be omitted or configured in some other way.
