Definitions
- the invention relates to a connector for high data rates, in particular for a high-frequency range greater than 500 MHz, preferably greater than 1 GHz, for applications in automotive technology
- Connectors which have a contact carrier made of a plastic material, at least one contact chamber, preferably a plurality of contact chambers, being arranged in the contact carrier for receiving a contact partner in each case.
- the contact partner is arranged at the end of an electrical conductor of an electrical line, for example a sheathed line, and is inserted into its associated contact chamber. After insertion, the contact partner is locked there at least once (so-called primary locking). This prevents the contact partner from being able to be moved out of its contact chamber by the action of tensile and / or compressive forces on the electrical conductor or the entire line.
- This primary locking is implemented in a known manner in that the internal geometry of the contact carrier has an undercut (for example a shoulder) over which an initially protruding spring tab of the contact partner and then a somewhat compressed spring tab can slide when inserted into the contact chamber when the contact partner enters his contact chamber is used. If the contact partner is used as intended in his contact chamber, the end of the spring tab comes into contact with the undercut and locks the contact partner in his contact chamber.
- undercut for example a shoulder
- a known connector has an elongated contact carrier with an approximately rectangular or square cross section.
- the invention has for its object to improve such a connector for data transmission over the sheathed line and the contact partner to a mating connector for transmission rates (data rates) greater than 500 MHz, preferably greater than 1 GHz.
- the solution to this problem provides that the undercut for the spring tab (or the like) of the contact partner in the contact carrier is designed as a passage opening in the contact carrier for each contact partner. This significantly improves the high-frequency properties of the connector, so that the data rates at which data is transmitted via the connector are also significantly increased.
- the cross section of the contact chambers is square or rectangular, each with a bevel in the longitudinal direction in a corner of the square or the rectangle.
- the contact chamber is preferably square or rectangular (viewed in cross section) over its entire course, the bevel being present at least in the region of the passage opening or additionally in front of or in addition to it or over the entire longitudinal course of the contact chambers.
- the passage opening for each contact chamber is provided on one side of the contact carrier, side by side there. The position of the respective passage opening is either symmetrical or offset to a longitudinal axis (which extends from the mating face with which the connector is inserted into a mating connector to the entry region of the line at the opposite end) of the contact carrier.
- At least one further passage opening is arranged on the side opposite the side with the at least one passage opening. This one more
- Through opening further improves the high-frequency properties of the connector to increase the transmission rates. It can, but does not have to be used to lock the contact partner inserted into the contact chamber.
- the connector has at least one contact spring, preferably two diametrically opposite contact springs, or a circumferential contact spring. This at least one contact spring is in electrical Active connection with a shield (for example a shielding braid) of the sheathed cable.
- the connector is connected to a corresponding contact element for the purpose of shielding, the corresponding contact element being arranged in or on a mating connector with which the connector can be plugged together to form a plug connection.
- the corresponding contact element being arranged in or on a mating connector with which the connector can be plugged together to form a plug connection.
- other contact elements are also used, which serve the purpose of the connection for realizing a continuous shielding between the plug connector and the mating plug connector
- the connector is designed for use in automotive technology.
- cables in particular cable sets, which consist of cables, at the ends of which connectors are arranged.
- Such connectors and the cables not only transmit energy (in particular for the voltage supply), but also signals, for example sensor signals or actuator signals, are also transmitted. With this transmission, it is essential to ensure good shielding against external interference and measures are also required so that the signals that are transmitted via the cables and the associated connectors do not radiate into their surroundings. This is particularly important in applications in automotive technology, in which such cables and connectors are sometimes installed or arranged in the smallest space. Therefore, the connector according to the invention can be used in a particularly advantageous manner in automotive engineering.
- the connector is advantageously used in a frequency range greater than 500 MHz.
- the line resistance not only remains the same or almost unchanged not only in the course of the cable (the line) but also in the area of the plug connector.
- Another effect according to the invention is to be seen in the fact that the presence of the at least one passage opening results in a significantly increased high-frequency shielding between the individual contact partners, in particular between two contact partners, which are arranged in their associated contact chambers.
- a connector for data transmission via the sheathed cable (also referred to as a cable or line) and the contact partner to a mating connector for transmission rates (data rates) greater than 500 MHz, preferably greater than 1 GHz the application in automotive engineering but also in other technical areas of application, for a significantly improved HF performance.
- FIG. 1 to 11 show a connector in which a contact carrier 2 is arranged in an outer housing 1 (also referred to as a protective collar).
- the outer housing 1 can be present, but need not be.
- the contact carrier 2 shown in the figures has two adjacent contact chambers, in each of which a contact partner 3 is inserted.
- One contact partner 3 is primarily locked in its associated contact chamber. This takes place, for example, in that a spring tab protruding from the contact partner slides along the inside of the contact chamber (and is thereby compressed somewhat) when the contact partner 3 is inserted into its contact chamber.
- the spring clip then resumes its original protruding position when the contact partner 3 is finally inserted into its contact chamber as intended.
- the spring tab comes into contact with an undercut.
- the undercut in the connector of this exemplary embodiment is designed as a passage opening in the contact carrier.
- the respective passage opening in the contact carrier 2 is elongated and preferably with a rectangular cross section (when looking at a plan view of the contact carrier 2 on its upper side).
- the contact partner 3 inserted into its contact chamber is accessible via this passage opening, but this is not important for the operation of the connector.
- This passage opening is important with regard to the high-frequency properties of the connector, since it significantly increases the data rates. For example, when looking at FIG. 10, it becomes clear that two through openings are arranged side by side on one side of the contact carrier 2. In this case, the two adjacent through openings are arranged symmetrically to the longitudinal axis of the elongated contact carrier 2.
- an asymmetrical arrangement can also be considered.
- the narrow ends of the passage openings are preferably aligned, but need not be.
- a strain relief 4 of a sheathed line 5 to which the plug connector is connected is also made to a strain relief 4 of a sheathed line 5 to which the plug connector is connected.
- unshielded sheathed cable 5 is, for example, a such an electrical line which has at least one internal electrical conductor (in the exemplary embodiment two internal electrical conductors) which are surrounded by an outer jacket. If it is a shielded sheathed cable (see FIGS.
- a shield for example a shielding braid or a shielding film, is arranged coaxially inside the outer sheath and surrounding the at least one internal electrical conductor.
- This shield is electrically contacted with at least one contact spring 6 of the connector.
- the connection to a corresponding shielding of a mating connector (not shown here) is established by means of the contact spring 6
- FIGS. 4 to 7 show the position of the passage openings, which serve to primary lock the contact partner within its contact chambers, and at least one opposite passage opening, preferably to further increase the high-frequency performance of the connector.
- FIG. 4 shows the contact carrier 2, viewed from above, in which two passage openings are arranged.
- the electrical line also has two electrical conductors and correspondingly arranged contact partners. If necessary, however, only one passage opening or more than two passage openings can also be provided on this side of the contact carrier 2, this being dependent on the number of electrical conductors in the line.
- FIGS. 5 and 7 show the cross section of a respective contact chamber in front of and behind the passage opening according to FIG. 4.
- the cross-section in this case is rectangular with a bevel in one corner of the rectangle.
- a square cross-section with a corresponding bevel can also be considered.
- FIG. 6 shows the situation of the contact chambers in the area of the two overhead openings (when viewing FIG. 6). It can be seen that these two overhead passage openings have the same cross section as in the area in front of and behind the passage openings. It can also be seen that there is a further passage opening located opposite the two passage openings. This further passage opening is arranged symmetrically to the longitudinal axis and the hole axis of the contact carrier present in FIG. 6. When viewing FIG. 6, there is a remaining web approximately in the upper half of the contact chambers, with a free space additionally being created in the lower half of the contact chambers, which extends into the further passage opening.
