Description

The invention relates to an electrical connector for connecting one or more coaxial cable to a printed circuit board, a connector element and a related use.

Coaxial cables are suitable in the frequency range of several kHz to several GHz high-frequency broadband signals such. Broadcast signals, radar signals or measuring signals to transmit. In particular, automotive coaxial cables are being used for high frequency automotive applications, such as automotive electronics. Radio antennas, GPS telematics or navigation, GSM mobile radio, RF Bluetooth applications and radio remote controls for keyless entry and parking heater used. Especially for such applications in the automotive sector, however, high demands are placed on corresponding connectors as an interface between one or more coaxial cables and a printed circuit board or board.

From the state of the art so-called FAKRA connectors (FAKRA = Fachkreis Automobil) developed specifically for use in the automotive sector are known, which are standardized in accordance with DIN 72594-1 or ISO 20860-1 and USCAR-18. A special feature of these connectors is the color coding as well as the mechanical coding of the different variants. Furthermore, the connectors can also be processed in pairs or in multiple combinations. In addition, emphasis was placed on the special requirements in the automotive sector such as temperature conditions, vibrations, etc.

Although conventional FAKRA connectors are designed to meet specific automotive requirements such as temperature variations and vibration, there is a problem with moisture or water coming from outside through the system Connectors can get to the PCB or board. In the case of technical devices and especially with measuring instruments, even a slight moisture in the interior - which can also be due to condensation, for example - can impair the function or cause measurement errors. In particular, electrical contacts are at risk, leakage currents or the failure of magnetic contacts can be the result. The penetration of moisture or liquid can thus lead to temporary malfunction up to the complete destruction of the circuit board and / or the associated technical device. Also, the moisture can lead to corrosion of parts of the cable, parts of the connector and / or parts of the circuit board, which limits the life of the corresponding parts.

The publication WO 2013/010680 A1 discloses an electrical connector having a housing of an electrically insulating material having sockets for receiving electrical contacts and a unitary seal of a flexible insulating material. The seal has a first portion and a second portion, the second portion protruding from the first portion. Further, the connector comprises an electrical shielding system having a first part surrounding the bushings and a second part, the second portion of the seal protruding from the second part of the shielding system. In addition, the connector may still have an inner seal which is disposed between the shielding system and the bushings and which protrudes from the second part of the shielding system.

The publication WO 2013/094774 A1 discloses a waterproof connector structure having three annular sealing members.

The publication CN 201 503 983 U discloses a coaxial RF connector having a sealing member disposed on an outer conductor.

Accordingly, a plug-in end is understood to mean an end region of the plug connector which, in the installed state, faces away from the printed circuit board or faces a complementary plug connector with which the plug connector according to the invention can be connected or connected. The term "assembled state" is understood to mean that the individual components of the connector are assembled or mounted ready for use. In particular, the connector is arranged in the mounted state on a mounting plate. The mounting plate may also be part of the electrical connector, or in other words, the electrical connector may also include the mounting plate.

The connector may comprise one or more coaxial conductors, which are preferably arranged substantially parallel to one another. Depending on the application, the connector may include two, three, four, five, six, seven, etc. coaxial conductors.

The shielding element is preferably formed as a cuboid hollow body having an opening for partially receiving the coaxial conductor on one of its side surfaces. In the assembled state, a portion of the coaxial conductor, which faces the printed circuit board, is located inside the hollow body. In other words, the shielding member covers the board-side end of the coaxial conductor. Preferably, the shielding element is integrally formed as an injection molded part. In particular, the shielding element forms part of the one or more coaxial conductors or the one or more outer conductors.

The connector element essentially consists of three sections, namely a plug-side section, a board-side section and a stop section, which is arranged between the plug-side section and the board-side section of the connector element.

The board-side portion of the connector member serves to fix the connector member to the shield member. Preferably, the board-side portion of the connector element is composed of at least two flexible holding members, one end of each holding member being connected to the abutment portion of the connector member. The other end, i. the board-side or in the assembled state of the circuit board facing the end of each holding member preferably has a projection which extends in the direction of the respective opposite holding element. In the mounted state, the holding elements surround the shielding element and thus fix the connector element to the shielding element arranged on the printed circuit board.

The stopper portion of the connector member is for arranging the connector to the shielding member and / or to a mounting plate. The mounting plate is used to install the connector in a designated slot, for example in a motor vehicle. The mounting plate has one or more through openings for receiving the at least one coaxial conductor, wherein the diameter of the at least one opening substantially corresponds to the outer diameter of the at least one coaxial conductor or of the outer conductor. In the mounted state, the at least one coaxial conductor is guided through the at least one opening of the stop section.

The stopper portion is preferably a plate having one or more through openings for receiving the at least one coaxial conductor, wherein the diameter of the at least one opening substantially corresponds to the outer diameter of the at least one coaxial conductor and the outer conductor. In the mounted state, the at least one coaxial conductor is guided through the at least one opening of the stop section.

Between the stopper portion and the mounting plate, a sealing system comprising at least two sections is arranged. Advantageously, the sealing system or at least a portion of the sealing system in the assembled state is positively arranged on the stop portion of the connector element and / or form-fitting manner to the mounting plate.

A first portion of the sealing system is annular or comprises at least one sealing ring, wherein the diameter of the sealing ring substantially corresponds to the diameter of the at least one coaxial conductor or the outer conductor. The at least one sealing ring is arranged in the mounted state along the circumference of the at least one coaxial conductor or outer conductor, in particular form-fitting manner. If the electrical connector comprises a plurality of coaxial conductors, a sealing ring is arranged on each of the coaxial conductors. The sealing ring has a circumferential nose or a circumferential projection, which extends in the assembled state to a lateral surface or outer surface of the coaxial conductor or outer conductor. In other words, the circumferential projection on the inside of the sealing ring is formed or extends to the interior of the sealing ring. As a circumferential projection of the sealing ring is understood in the sense of this description, a projection which extends over the entire circumference of the sealing ring.

A second section of the sealing system is designed and arranged in such a way in that it circumscribes the at least one coaxial conductor on a closed path, wherein the cross section of the area enclosed by the second section of the sealing system is greater than the cross section of the at least one coaxial conductor and thus also larger than the cross section of the first section or the sealing ring of the sealing system. The second portion of the sealing system may be formed, for example, rectangular or frame-shaped. In other words, the second portion of the sealing system may include a rectangular area, wherein the area enclosed by the second portion is larger than the cross section of the at least one coaxial conductor. However, the second section of the sealing system can also include any other surface, for example a circular area, which is larger than the cross section of the at least one coaxial conductor. The second portion of the sealing system has a circumferential projection which extends to the mounting plate. As a circumferential projection of the second portion of the sealing system is understood in the sense of this description, a projection which extends over the entire circumference of the enclosed by the second portion of the sealing system surface edge. If the electrical connector comprises a plurality of coaxial conductors, the second section of the sealing system preferably circulates all coaxial conductors together.

The electrical connector according to the invention can advantageously prevent penetration of moisture or liquid, in particular water, into the board-side end of the connector and / or penetration of moisture or liquid to the circuit board substantially. Thus, malfunction and / or destruction of the circuit board or the associated electrical device due to the ingress of moisture or liquid can be avoided. Also, corrosion of susceptible parts of the cable, parts of the connector and / or parts of the circuit board can be avoided, which increases the life of the corresponding parts and thus the life of the cable, the connector and / or the circuit board itself. The electrical connector according to the invention can thus better meet increased requirements, especially in the automotive sector. So can the connector according to the invention are used especially in sophisticated equipment, for example, given a certain limit for the humidity and / or storage conditions.

In a preferred embodiment of the electrical connector, the sealing system is designed such that it has a leak in the mated or mounted state according to the protection class IP67 and / or IP68 according to DIN EN 60529. The sealing system preferably keeps in 1 m water depth for at least 48 hours tight. Ingress of moisture into the board-side end of the connector and / or penetration of moisture to the circuit board can thus be prevented even at a relative humidity of the environment of ≤ 99%.

The sealing system may for example be made of plastic, in particular of elastic plastic and / or rubber. Preferably, the stopper portion and the mounting plate are arranged to each other such that they compress the intermediate sealing system and thereby deform it elastically. Due to the thus generated contact pressure of the sealing system relative to the stopper portion and the mounting plate increased density can be achieved.

In a further preferred embodiment of the electrical connector, the connector element is designed as an injection molded part.

Advantageously, the plug-side portion, the stopper portion and the board-side portion of the connector element are integrally formed, preferably made of plastic, and / or manufactured as an injection molded part. This saves time and costs in the production and at the same time ensures a stable cohesion of the connector.

In a further preferred embodiment of the electrical connector, the sealing system is sprayed onto the stopper portion.

By spraying the sealing system on the abutment portion, the sealing system is firmly connected to the stopper portion and thus provides increased strength and tightness. The sealing system may thus also be considered as part of the connector element, or in other words, the connector element may also comprise the sealing system. In the mounted state, the surface facing away from the abutment portion of the sealing system presses against the mounting plate of the electrical connector.

In a further preferred embodiment of the electrical connector, the first portion of the sealing system further comprises a circumferential projection which extends to the mounting plate. Also, the second portion of the sealing system may include a circumferential projection extending to the abutment portion of the connector element.

The circumferential projection of the first portion of the sealing system which extends to the mounting plate may also be referred to as the third circumferential projection. The circumferential projection of the first and / or the second portion of the sealing system, which extends to the stop portion of the connector element may also be referred to as a fourth circumferential projection.

As a circumferential projection of the first portion of the sealing system is understood in the sense of this description, a projection which extends over the entire circumference of the enclosed area of the first portion of the edge. A circumferential projection of the first portion of the sealing system, which extends to the mounting plate and / or the stopper portion, provides for increased tightness between stopper portion and mounting plate. In particular, the projection may consist of an elastic material such as elastic plastic or rubber, which is elastically deformed or compressed in the mounted state. Due to the resulting restoring force or the resulting counter pressure of the elastic projection against the Stop section and / or against the mounting plate, the tightness can be increased. In addition, the projection can also compensate for possible unevenness of the stopper portion and / or the mounting plate better, which also increases the tightness of the sealing system.

In a further preferred embodiment of the electrical connector, the at least first section of the sealing system is connected to the second section of the sealing system via at least a third section of the sealing system.

For example, the at least first portion of the sealing system may be annular or formed as a sealing ring. The second section of the sealing system can be designed as a rectangular frame. The at least first portion of the sealing system may be disposed in the area enclosed by the second portion of the sealing system. In particular, the at least first section of the sealing system or the at least one sealing ring can be arranged within a surface enclosed by the rectangular second section of the sealing system. In the case of multiple seal rings, all seal rings may be located within the area enclosed by the second portion of the seal system. The third portion of the sealing system, which connects the first and the second portion of the sealing system, may be formed as a web. In particular, one end of the third portion of the sealing system may be disposed on an outer surface of the first portion and the sealing ring, respectively, and the other end of the third portion of the sealing system may be disposed on an inner surface of the rectangular second portion of the sealing system. The at least one third section of the sealing system preferably connects the at least one sealing ring to the rectangular sealing frame, in the enclosed area of which the at least one sealing ring is arranged.

The third section ensures a higher stability of the whole as a connecting element between the first and second sections of the sealing system Sealing system. In particular, all three sections of the sealing system can be integrally formed or manufactured. This facilitates the manufacture and also the assembly of the electrical connector.

In a further preferred embodiment of the electrical connector, the sealing system is arranged or molded on a circuit board-side surface or on a plug-side surface of the stopper portion.

In the context of this description, a plug-side surface of the stop section is understood to mean a surface of the stop section which faces away from the printed circuit board or faces a complementary plug connector. Accordingly, a board-side surface of the stopper portion is understood to mean a surface of the stopper portion which faces the printed circuit board.

If the sealing system is arranged or sprayed on a board-side surface of the abutment portion, the mounting plate, starting from the abutment portion, offset in the direction of the board-side end of the connector and has openings or holes through which in the assembled state of the board-side portion 28 of the connector element 20 protrudes. If the sealing system is arranged or sprayed on a plug-side surface of the stop section, the mounting plate, starting from the stop section, is offset in the direction of the plug-side end of the plug connector and has openings or bores through which the plug-side section 22 of the connector element in the assembled state 20 protrudes.

In the context of this description, a "positive-locking arrangement" of two elements is understood in particular to mean that the elements are arranged in a sealing manner. In a positive or sealing arrangement of two elements, the elements are thus formed or arranged such that substantially no moisture or liquid can pass from the outside between the elements.

In a further preferred embodiment of the electrical connector, the electrical connector comprises at least two coaxial conductors. The sealing system comprises at least two annular first sections, which are connected to one another via connecting straps.

In particular, the electrical connector may comprise two, three, four, five, six, seven, etc. coaxial conductors. The sealing system may comprise two, three, four, five, six, seven, etc. ring-shaped first sections or sealing rings. The connecting straps connect the individual first sections or the sealing rings of the sealing system and thus ensure greater stability. Preferably, all first sections and the connection bracket of the sealing system are integrally formed.

In a further preferred embodiment of the electrical connector, the stopper portion has a terminal configuration and a complementary terminal configuration to combine a plurality of electrical connectors together or to connect to a combined electrical connector.

The connection configuration may e.g. have one or more grooves, while the complementary connection configuration may have one or more projections. The projections of a stopper portion can be accurately inserted into the grooves of another stopper portion or locked by means of a latching mechanism. Thus, it is possible to adapt the necessary number of coaxial conductors modular. For example, a connector having two coaxial conductors and a connector having three coaxial conductors may be interconnected via the connector configuration to form a connector having five coaxial conductors. Preferably, all connectors or the stopper portions of the connectors are arranged on a common mounting plate.

Detailed description of the drawings

The location selected in the present description, such as location. B. top, bottom, side, etc. are each related to the immediately described and illustrated figure and are mutatis mutandis to transfer to a new position to the new situation. Under a plug-side end 16 of the electrical connector that end of the electrical connector is understood, which is connectable or can be plugged together with a complementary connector. The plug-side end 16 is that end which is remote from a printed circuit board or board 50, to which the electrical connector is electrically connected. Under a board-side end 18 of the electrical connector that end of the electrical connector is understood, which faces a circuit board or board 50 and / or with the circuit board or board 50 is connectable. However, the terms "plug-in" and "board-side" may not only refer to the electrical connector as such, but are also to be understood accordingly with respect to components of the electrical connector.

The FIG. 1a shows a coaxial conductor 10 and arranged on the coaxial conductor 10 shielding element 40 according to an embodiment of an electrical connector according to the invention.

The coaxial conductor 10 comprises an inner conductor 12, an outer conductor 13 and an insulator 42. The cylindrical inner conductor 12 is surrounded by the hollow cylindrical outer conductor 13. In the region of the plug-side end 16 of the connector, the hollow cylindrical outer conductor is arranged concentrically around the cylindrical inner conductor 12, ie the outer surface of the inner conductor 12 is substantially constantly spaced from the inner surface of the outer conductor 13. In the region of the board-side end 18 of the connector, in which the shielding element 40 is arranged, the inner conductor 12 has a 90 ° bend (see, for example, FIGS FIG. 3 or 8th ), so that the inner conductor 12 with a circuit board 50 is electrically connected, in particular to a contact of the circuit board 50 is soldered. The lateral surface of the outer conductor 13 is deformed or widened in the region of the board-side end 18 of the connector such that four soldering pins 45 are formed, which are electrically connectable to the printed circuit board 50 or solderable to intended contacts of the printed circuit board 50. However, the number of solder pins 45 of the outer conductor 13 may differ from four depending on the circuit board design. The inner conductor 12 is electrically separated from the outer conductor 13 by means of an insulator 42, which is arranged between the inner conductor 12 and the outer surface of the outer conductor 13. The insulator may be a non-conductive, ie insulating material or dielectric. The dielectric may consist proportionally or completely of air.

The shielding element 40 surrounds a board-side section of the coaxial conductor 10 and serves to protect the coaxial conductor and the shielding of interfering, in particular high-frequency, signals. The shielding element 40 is therefore preferably made of metal.

A notch or groove 15 formed on the outer conductor 13 and a projection 41 formed on the outer conductor 13 and the shielding member 40 serve to arrange and fix a connector element 20.
