Description

Strong Power Socket

The invention relates to a power outlet for at least two branch plugs, whereby all the connection sleeves for the cooperating plug pins 5 are arranged substantially aligned, preferably in the longitudinal direction of the outlet.

Such double or multiple row sockets are already known as implementations in which the sockets are lined up so that the wires connected to the branch plugs having angular outputs or socket transformers hang down when the socket is 10 wall mounted horizontally. The same is true of loose sockets (extension sockets).

For these types of sockets, the isolation requirements for common mains voltage between the various phases and possibly per country will result in the conventional 15 busbars inevitably having a complicated shape in terms of electrical connection between the respective bushings and the respective socket for supplying the respective socket.

One object of the invention is to provide a simplified construction of such sockets, for example with a view to more rational manufacturing.

In this context, it is noted that, particularly in the electronics industry, circuit boards with a printed or printed circuit board are widely used, * which can be accomplished by a variety of known methods or processes. An example of such a use of a circuit board 25 is GB 2,139,017, which discloses low-power module interfaces soldered to a circuit board for telecommunication / data purposes. However, this example is far from the high current sockets to which the present invention relates.

'. Reference is also made to Swedish Patent Publication No. SE 448,414, which also relates to. 30 primarily telecommunications installations. The design is clearly intended for use as a power adapter for low-voltage devices between the power outlet and the plug. In this case, the circuit board has components for certain functions that are not typically found in high-voltage or domestic installations that are connected to a public power distribution network. In this connection, it is particularly noteworthy that the patent publication discloses the installation of connector parts or connector sleeves on both sides of a circuit board.

Finally, reference is made to U.S. Patent 4,385,791, which largely discloses structures similar to those described in the aforementioned Swedish Patent Publication.

Based on the problems outlined above, it has been found particularly advantageous to use circuit board technology for the specific sockets 10 disclosed herein to provide a new socket design that is simple and inexpensive to manufacture, while being safe and convenient for use, e.g.

This object is achieved by a socket such as the one initially described in which the terminal sleeves and terminal mounts are arranged on a common socket, which is an insulating circuit board provided with the necessary circuits in the form of a conductive metal layer between the terminal mounts and the terminal socket, respectively. . the circuits are mounted on one side of the circuit board, while the sockets and the socket! The clips 20 are located substantially on one side of the circuit board.

* *; · · As will be explained in the following description, circuit board technology has the great advantage of providing internal: electrical connections in such sockets when the necessary current V: paths must be angled or turned to reach the terminals to which 25 currents are fed.

.. * When the present invention is based on the fact that all interface elements are arranged on one side of a circuit board, significant advantages over the aforementioned prior art constructions are achieved in both manufacturing and installation, in the latter case in terms of space requirements and placement. Further advantages are achieved by the fact that the circuit board according to the invention also serves as a base board having a certain

• I

3 114664 Caustic Strength. In this way, the circuit board is embedded throughout the socket structure so that the circuit board itself contributes to its mechanical strength and rigidity as a whole. Finally, the manufacture of these new circuit board-based sockets is largely cost-saving, e.g. thanks to a sharp reduction in the number of individual parts to be installed.

It will be appreciated that the solution according to the invention is particularly advantageous for double or multiple row type sockets, especially for wall mounting, but also for loose branch extension sockets.

Referring now to the accompanying drawings, an exemplary embodiment of a socket according to the invention is illustrated in greater detail by way of example, with Fig. 1 showing the top of a circuit board 15 with integrated sockets and clips and Fig. 2 showing the same circuit board underneath.

The circuit board itself is denoted in the drawings by reference 1, and on the upper surface IA shown in Fig. 1, two terminal sleeve groups 2A, 2B and 2C and 3A, 3B and 3C respectively are mounted along the longitudinal axis AX of the circuit board. These two interfaces ···. the sleeve group is each based on a central sleeve 2B and 3B, respectively, which is used for grounding, the placement of which depends on the norm or standard to be fulfilled.

:. ΐφ 25: Five interface clips 5, 6, 7, 8 and 9 are further fitted to circuit board 1, two of which, namely clips 5 and 6, are blind or changeover clips, as shown in Figure 2 * '*. it turns out.

*). 30 Blind or changeover clips (one or more) are placed on the same level and • · with the other connector clips so that a similar 114664 4 socket termination is generated.

The current passage patterns shown in Figure 2 comprise three connections, namely, the current path 11 from the holder 8 to the sleeves 2C and 3C, the current path 12 from the holder 7 5 to the sleeves 2A and 3A, and the earthing path 13 between the connector holder and two earthing sleeves 2B and 3B. With the present flow paths 11, 12 and 13 having variable widths for appropriate utilization of the circuit board surface, the insulating spaces 21 and 22 between adjacent portions of the current paths are formed to be approximately the same width over the entire length.

10

In order to provide a secure electrical connection between the current paths and the contact bushings or the terminal clamps respectively, soldering or the like at the appropriate locations or locations is routinely provided.

With a structure similar to the one described above, the circuit board 1 provides both a base board for the mechanical installation of the connector sleeves and connector holders and an electrical connection device for the necessary power connections in the particular types of sockets to which the invention relates. These sockets can, of course, also be manufactured without the earthing sleeves 2B and 3B shown in Figure 1.
