HOLDING FRAME FOR A PLUG CONNECTOR OR A MOUNTING FLANGE FOR HOLDING A CIRCUIT BOARD

Abstract

Disclosed is a holding frame for accommodating a circuit board, wherein the holding frame has a substantially rectangular basic shape and has two holding arms sticking out perpendicularly from the frame plane, each holding arm having a groove in which the circuit board can be held. A circuit board can thus be integrated in a heavy-duty plug connector in a mechanically stable yet low-wear manner.

Description

EXEMPLARY EMBODIMENT

[0016] An exemplary embodiment of the invention is shown in the drawings and is explained in more detail below. Here:

[0017] FIG. 1 shows a perspective illustration of a holding frame according to the invention,

[0018] FIG. 2 shows a perspective illustration of the holding frame according to the invention in which a circuit board is held and with which a plug connector is connected,

[0019] FIG. 3 shows a perspective illustration of a heavy plug connector with the integrated holding frame and the circuit board fixed to it and the plug connector connected to it,

[0020] FIG. 4 shows a perspective illustration of a mounting flange with the integrated holding frame and the circuit board fixed to it and the plug connector connected to it, and

[0021] FIG. 5 shows a sketch showing the principle of a process in which two holding frames are plugged together.

[0022] The figures contain illustrations that are in part simplified or schematic. In some cases identical reference signs have been used for elements that are equivalent but not in all cases identical. Different views of the same elements may be scaled differently.

[0023] FIG. 1 shows a perspective illustration of a holding frame 1 according to the invention. The holding frame 1 comprises an essentially rectangular base body 2. Two holding arms 3 protruding from the frame plane are formed at the base body 2. The holding arms 3 are located at the narrow sides of the base body 2, and are aligned parallel to one another. The holding arms 3 are located on the so-called connection side of the holding frame 1. A groove 4 is formed in each of the holding arms 3. A circuit board 5 can be inserted into the grooves 4 of the holding arms 3. In this way the circuit board 5 is held in the holding frame 1 in a vibration-proof manner and is, in particular, fixed to it.

[0024] It can be seen in FIG. 2 that a plug connector 6 is soldered to the circuit board 5. The plug face 7 of the plug connector 6 protrudes on the plug side out of the base body 2 of the holding frame 1. A guide arm 8 protruding from the frame plane is formed on the plug side of each of the narrow sides of the base body 2. The guide arms 8 serve to provide accurate alignment of the holding frame 1 with a further holding frame in a mating plug connector or a mounting flange. The guide arms 8 are arranged with a mutual offset in their height. Due to the offset arrangement of the guide arms 8, the holding frame 1 can be plugged together with a holding frame of identical construction. The holding frames here can be installed in a plug connector 10 or in a mounting flange 10. Openings 9 are formed in the holding frame 1 above or below the guide arms 8. The guide arms 8 of another holding frame 1 can engage here in the plugging process. This process is explained more precisely further below.

[0025] A plug connector 10 is shown in FIG. 3 and a corresponding mounting flange 10 in FIG. 4. A holding frame 1 according to the invention with a circuit board 5 and a plug connector 6 mounted thereon is contained in both the plug connector 10 and in the mounting flange 10.

[0026] The holding frame 1 can be inserted or mounted, together with the circuit board 5, both from the fronti.e. the plug sideor also from the reari.e. the connection sideinto a plug connector housing 10 or a mounting flange 10.

[0027] The process in which a pair of holding frames 1, 1 are plugged together is shown in FIG. 5. During the plugging process, the guide arms 8 of the one holding frame 1 engage in the openings 9 of the opposing holding frame 1 and vice versa. As a result, the holding frames 1, 1 are accurately positioned with respect to one another. The guide arms 8 and the associated openings 9 together act as means of guidance during the plugging process. As a result, the plug connectors 6 located on the circuit board 5 can be plugged together with low wear. The guide arms 8 and openings 9 here act at the same time as so-called encoding means. It is not possible for the plug connector 10 and mounting flange to be plugged in in a twisted manner.

[0028] Even though various aspects or features of the invention are respectively shown in combination in the figures, it is clear to the expert except when otherwise stated that the combinations illustrated and discussed are not the only possibilities. In particular, units corresponding to one another, or complexes of features from different exemplary embodiments, can be exchanged for one another.
