Description

High-speed connector

Technical Field

The present utility model relates to connectors, and more particularly, to a high-speed connector with a compact structure.

Background

In recent years, vehicles have been equipped with many in-vehicle electronic devices. These in-vehicle electronic devices provide a wide range of functions such as sensors, control functions, and the like. These in-vehicle electronics provide typical consumer electronic functions, navigation control and/or safety features, as well as feedback control for automatic driving, for example. For data communication between individual on-board electronic components, data networks have been established within the vehicle. These data networks communicate at high data rates to enable secure and reliable communications. Typically, the data network is based on an ethernet network.

However, as the data transmission rate increases, EMC (electromagnetic compatibility) performance of the connector decreases, and an electromagnetic shielding policy needs to be formulated for an increased crosstalk level and reduced EMC characteristics, but additional electromagnetic shielding components may cause difficulty in miniaturization of the connector.

Detailed Description

In the following description, numerous specific details are set forth. It may be evident, however, that the embodiments of the present utility model may be practiced without these specific details. In other instances, well-known circuits, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.

References in the specification to "one embodiment," "an example embodiment," etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Furthermore, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

As in-vehicle electronics evolve, so too does the demand for higher data transfer rates. However, the higher the data rate, the higher the level of crosstalk between the individual branches of the network, especially if the connectors and/or cables of these branches are arranged adjacent to each other and/or substantially parallel to each other. This is often the case if a cable harness is used to wire the vehicle. In addition, as the number of connectors and cables in the vehicle body increases, the space for wiring decreases. This may result in a centralized arrangement and parallel orientation of a plurality of connectors and/or cables, wherein a plurality of data lines meet, for example, near a control device and/or at a mating interface of such a control device.

Further, as the data rate increases, EMC (electromagnetic compatibility) performance of the connector may decrease. To improve electromagnetic shielding performance to increase data rates, shielding members are often added to the connector to prevent radiation from entering and/or exiting the connector housing. However, the known shielding members are additionally provided, which may result in a large and heavy connector. Moreover, this is undesirable, especially in vehicles, due to the limited installation space.

The present disclosure proposes a compact connector for high speed data transmission applications. In the following embodiment, a case of three-hole site, i.e., three-terminal connector is shown. It should be understood that the structures described in this disclosure may be expanded in multiple holes as standard structures, for example, to a single row of four holes, five holes, or any other number, or to double rows or any other number.

Fig. 1 (a) and 1 (B) are perspective views illustrating an example connector according to the techniques of the present disclosure. Fig. 2 is a rear view illustrating an example connector in accordance with the techniques of this disclosure. Fig. 3 is an exploded view illustrating an example connector in accordance with the techniques of this disclosure. Fig. 4 is a cross-sectional view taken along line A-A in fig. 3. Fig. 5 is a rear view illustrating an example connector in accordance with the techniques of this disclosure.

As shown in fig. 1 (a), 1 (B) and 2, the connector of the exemplary embodiment includes a plastic housing 1, a metal housing 2, a transmission terminal 3 and a metal outer shield plate 4. As shown in fig. 4, the hollow plastic housing 1 and the plastic housing 2 are installed in a mating manner. A transmission terminal 3 is arranged in the plastic shell 2.

In this embodiment, as shown in fig. 2, the connector includes three transmission terminals 3, and is thus a three-terminal connector. The transmission terminal 3 includes a first end 31 and a second end 32.

The first end 31 is adapted to contact a conductive terminal (not shown) of a mating end to form an electrical connection. The second end 32 is connected (e.g., soldered) to a circuit board, such as a PCB, not shown. The first end 31 and the second end 32 may have different directions of extension, i.e. be angled. In this embodiment, the first end 31 is substantially perpendicular to the second end 32, thereby forming a right angle connector. In this case, the first end 31 is along the insertion direction (y-direction) of the connector, and the second end 32 is along the vertical direction (z-direction) of the connector and protrudes from the bottom surface of the metal housing 2, as shown in fig. 3.

The transmission terminal 3 is held in the metal housing 2. The metal housing 2 may be made of zinc alloy, for example. As shown in fig. 2, the metal housing 2 includes a main body portion 22 and a sleeve 21. The number of sleeves 31 corresponds to the number of transmission terminals 3 such that the first end 31 of each transmission terminal 3 is disposed within a separate sleeve 31 and each first end 31 is electrically insulated from the corresponding sleeve 31. The main body portion 32 defines a cavity therein which accommodates the transmission terminals 3 and communicates with the sleeves 21, as shown in fig. 4. At the time of installation, the transmission terminals 3 may be inserted into the metal housing 2 from the rear side (y direction) of the metal housing 2 to insert the first ends 31 of the respective transmission terminals 3 into the sleeve 21. As shown in fig. 4, the first end 31 of the transmission terminal 3 may be formed with an insulating member 33 wrapping the first end 31. The insulator 33 may abut an inner wall of the sleeve 21 to maintain the position of the first end 31. As shown in fig. 1 (a), after the plastic housing 1 and the plastic housing 2 are fitted, all the sleeves 21 are surrounded by the plastic housing 1.

Referring to fig. 3, one or more rib structures 11 are provided on the inner wall of the plastic housing 1. These bead structures 11 form an interference fit with the outer wall of the metal shell 2 to hold the metal shell 2 in place. Furthermore, the asymmetrical design of the bead structure 11 prevents the metal shell 2 from being inserted in the wrong orientation, e.g. upside down. Furthermore, the bead structure 11 may be connector-type specific, thereby preventing incorrect assembly of components (e.g., metal shells) of different types of connectors together during installation.

Returning to fig. 2, the connector of the present embodiment may further include a metal outer shield plate 4. The number of the metal outer shield plates 4 corresponds to the number of the transmission terminals 3. As shown in fig. 4, each of the metal outer shield plates 4 is provided at the rear side of the first end 31 of the corresponding transmission terminal 3. The metal outer shield 4 may be located inside the metal housing 2 and in contact with the transmission terminal 3. The metal outer shield 4 can provide electromagnetic shielding of the transmission terminal 3 from the outside, especially from the rear. The metal outer shield 4 may be fixed to the rear side of the metal housing 2, for example by riveting or welding, as shown by the dashed box in fig. 5. The shape of the metal outer shield 4 may be matched with the shape of an opening into which the first end of the transmission terminal 3 is inserted at the rear side of the metal housing 2 to improve the electromagnetic shielding effect.

According to the utility model, the first end 31 of each transmission terminal 3 is arranged within a separate sleeve 21 such that the first ends 31 of adjacent transmission terminals 3 are separated by a metal shield. Further, the rear side of each transmission terminal 3 is provided with a corresponding metal outer shield plate 4. This ensures electromagnetic shielding between the parallel arranged transmission terminals 3 and between the transmission terminals 3 and the outside, e.g. other connectors, cables, thus enabling high speed data transmission up to 25 Gbit/s. In addition, the present embodiment can realize a small-sized and compact high-speed connector by realizing electromagnetic shielding by the metal housing 2 holding the transmission terminal 3 and minimizing the extra electromagnetic shield.

In addition, the three-terminal connector of the embodiment fills the blank that the same type of products in the current market have no three-terminal design, can realize the requirement that the existing 1, 2, 4 and 6-bit Ethernet connectors can not realize the simultaneous transmission of three-bit Ethernet signals, can ensure that the signal transmission of three channels is not interfered with each other, and can realize the high-speed transmission of three-channel signals.

The embodiments, implementations and aspects described above have been described in order to allow easy understanding of the utility model and are not limiting of the utility model. On the contrary, the utility model is intended to cover various modifications and equivalent arrangements included within the scope of the appended claims, which scope is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures as is permitted under the law.
