Description

相邻部件间的光数据连接器Optical data connectors between adjacent components

本发明涉及一种相邻部件间的光数据连接器，这些部件在部件构件内平行靠在一起，在该连接器内，至少一束相应的已调制光束通过相邻部件间的间隙从一个部件发射到相邻部件，一个部件至少装有一个发射组件，该发射组件备有一个用来发射微发散光束的激光二极管装置，位于相对位置的部件至少装有一个接收组件，该接收组件备有一个光电二极管装置。The present invention relates to an optical data connector between adjacent components which are brought together in parallel within a component structure, in which connector at least one corresponding modulated light beam is passed from one component to another through the gap between the adjacent components To emit to adjacent components, one component is equipped with at least one transmitting component, which is equipped with a laser diode device for emitting a micro-divergent beam, and the component at the opposite position is equipped with at least one receiving component, and the receiving component is equipped with a Photodiode device.

已知一种这种类型的光数据连接器，如DE 3739629A1。然而，这种已知的光数据连接器只能在一个方向上发射，这是由于每个部件只在一边有发射组件而在另一边有接收组件。An optical data connector of this type is known, such as DE 3739629A1. However, such known optical data connectors can only emit in one direction, since each part only has a transmitting component on one side and a receiving component on the other side.

还已经知道一些相邻部件间的光数据连接器(例如，见“基于用全息照像耦合元件光导盘的光电连接器”，光学工程(Opticalengineering)30(10)，1620-1623(10月，1991)，它们允许双向工作。在这种情况下，光连接通过在印刷电路板背面上的光导玻璃盘来实现。在这种情况下，将光束耦合入和耦合出光导玻璃盘存在很多困难。Optical data connectors between adjacent components are also known (for example, see "Optical connectors based on optical guide discs with holographic coupling elements", Optical Engineering (Opticalengineering) 30(10), 1620-1623 (October, 1991), they allow bi-directional operation. In this case, the optical connection is made through a light-guiding glass disk on the back of the printed circuit board. In this case, there are many difficulties in coupling light beams into and out of the light-guiding glass disk.

因此本发明的目的是，提出一种本文开头描述的那种形式的相邻部件间的光数据连接器，它以结构简单为特色并允许双向发射和接收工作。It is therefore the object of the present invention to provide an optical data connector between adjacent components of the type described at the outset, which is characterized by a simple construction and allows bidirectional transmit and receive operation.

此目的在本文开头描述的那种形式的光数据连接器中通过以下方法得以实现，此方法是在每个部件的一边提供一个单件的发射和接收组件，该组件含有一个激光二极管装置和一个光电二极管装置(PD)，在发射和接收组件中激光二极管装置和光电二极管装置平行于部件印刷电路板安放，并按特定数值移位彼此相对放置，在这两组装置之间，在相应的光束路径上，备有偏转光束90°角的表面平面反射镜，并且其中一束光束穿过部件印刷电路板上的开孔。This object is achieved in an optical data connector of the type described at the outset by providing on one side of each part a single-piece transmitting and receiving assembly containing a laser diode arrangement and a Photodiode device (PD), where the laser diode device and the photodiode device are placed parallel to the component printed circuit board in the transmitting and receiving assembly, and are placed relative to each other by a specific value shift, between these two groups of devices, in the corresponding light beam Along the way, there are surface plane mirrors that deflect the beam at a 90° angle, and one of the beams passes through an opening in the component's printed circuit board.

本发明光数据连接器的显著特点是结构简单。实际结果是，只要用单个组件进行发射和接收，部件上的开孔在该组件的安装位置，一个单个组件可以在双向上发射和接收。The notable feature of the optical data connector of the present invention is its simple structure. The net effect is that a single component can transmit and receive in both directions, as long as a single component is used for transmitting and receiving, and the openings in the part are where the component is mounted.

本发明的光数据连接器有利的改进结构，其特征在于，发射和接收组件包括有多个排列在一起的激光二极管装置和光电二极管装置。An advantageous development of the optical data connector according to the invention is characterized in that the transmitting and receiving assembly comprises a plurality of laser diode arrangements and photodiode arrangements arranged together.

下面用附图中所示的实施例更详细地阐述本发明。The invention is explained in more detail below using an embodiment shown in the drawing.

在图中：In the picture:

图1示出了本发明的光数据连接器的基本结构，以及Fig. 1 shows the basic structure of the optical data connector of the present invention, and

图2示出了构成光数据连接器的发射和接收组件的基本结构，该组件可以在双向上发射和接收。Figure 2 shows the basic structure of the transmitting and receiving components that make up an optical data connector, which can transmit and receive in both directions.

图1示出了根据本发明的由两个部件印刷电路板BGL组成的光数据连接器的基本结构，这两块板平行排列在一起。在每个电路板上排列着发射位置S0和接收位置E0，相对排列的是另一个部件印刷电路板上的相对应的接收位置E0和发射位置S0。图1中可以看到光束的发散，其结果是光连接允许位置上的误差而不必进行调整。光束发散的最佳值决定于在给定的误差范围和连接长度内接收最大功率。Fig. 1 shows the basic structure of an optical data connector according to the invention consisting of two component printed circuit boards BGL, which are arranged in parallel. On each circuit board, a transmitting position S0 and a receiving position E0 are arranged, and oppositely arranged are corresponding receiving positions E0 and transmitting positions S0 on the printed circuit board of another component. The divergence of the beam can be seen in Figure 1, the result of which is that the optical connection allows for errors in position without adjustment. The optimum value for beam divergence is determined by receiving the maximum power within a given tolerance and connection length.

发射位置主要包括一个激光二极管，接收位置主要包括一个光电二极管。一个发射和接收组件SEM内可以容纳多个发射位置S0和接收位置E0。The transmitting location mainly includes a laser diode, and the receiving location mainly includes a photodiode. Several transmitting locations S0 and receiving locations E0 can be accommodated in one transmitting and receiving module SEM.

图2原理上示出了这种发射和接收组件特别实用的结构。透镜L与激光二极管LD和透镜L与光电二极管PD组合以形成光束。在子组件内这些透镜分别与激光二极管LD或光电二极管PD集成在一起。这个集成体还可以包括电光转换需要的电路。图2所示发射和接收组件的实施例中，子组件应平放，以便减少组件的高度。通过表面平面反射镜SP实现向发射方向的反射。这里，所有需要的元件都放在一个单个组件内。组件SEM可以安放在一个部件的两边以便实现双边的连接。如图2所示，如果在部件的印刷电路板上和组件相应的外罩壁上备有孔隙，那么单个组件可以在两个方向上发射和接收。FIG. 2 shows in principle a particularly practical construction of such a transmitting and receiving assembly. The lens L is combined with the laser diode LD and the lens L with the photodiode PD to form a light beam. These lenses are integrated with a laser diode LD or a photodiode PD, respectively, within the subassembly. This integrated body may also include the circuits required for electro-optical conversion. In the embodiment of the transmit and receive assembly shown in Figure 2, the sub-assemblies should lie flat in order to reduce the height of the assembly. Reflection in the direction of emission is achieved by means of the surface plane mirror SP. Here, all required components are placed in a single component. Components SEM can be placed on both sides of a component to achieve bilateral connections. As shown in Figure 2, a single module can transmit and receive in both directions if apertures are provided on the component's printed circuit board and in the module's corresponding housing wall.

按这样安排，一个组件可以包括很多并排安放在一起的发射和接收通道，最小通道间距范围可以是5到10毫米。Arranged in this way, a module can include many transmit and receive channels arranged side by side, with a minimum channel spacing in the range of 5 to 10 mm.

最后把本发明的光数据连接器的优点再次归纳如下：Finally, the advantages of the optical data connector of the present invention are summarized as follows:

相邻部件的光连接不再需要通过背面，背面被释放，简化了部件的布线。Optical connections to adjacent components no longer need to go through the backside, which is freed, simplifying component routing.

该光连接器几乎可以按任意高速率传送数据，速率仅受电光转换器的限制。The optical connector can transfer data at almost arbitrarily high rates, limited only by the electrical-to-optical converter.

在部件印刷电路板上可以随意排列发射和接收组件，甚至直接放在高频源和接收器的附近。The transmitting and receiving components can be arranged freely on the component printed circuit board, even placed directly in the vicinity of the high-frequency source and receiver.

光数据连接器中没有阻抗匹配问题。There is no impedance matching problem in optical data connectors.

光数据连接是无接触的连接，由此省去了插头和插座连接器。Optical data connections are contactless connections, whereby plug and socket connectors are omitted.

平行通道间的串音可以忽略，它与数据速率无关，即使在高频时也是如此。Crosstalk between parallel channels is negligible, independent of data rate, even at high frequencies.
