Abstract

A locking mechanism (12) has a rectangular locking plate (13') arranged partially within a plug-receiving chamber (11a) and extended parallel with a through bore (50). The plate comprises a pair of ends. A connector connects one end of the plate with a housing (1). Another connector for connecting the other end with a telecommunication plug (34) has a locking projection carried by the locking plate for engagement with a corresponding stop surface associated with the plug, when the plug is fully inserted within the chamber.

Description

The invention relates to an adapter plug housing for receiving a plug part and an adapter socket housing for receiving a socket part according to the preamble of claim 1.

Adapter housings of the generic type allow the use of the plug and socket parts used in them even in harsher environment - for example in production plants or vehicles - by reaching a higher compared to the protection class of the plug part protection class such. IP65 or IP67.

A first such arrangement for a telephone plug is from the US 4,349,236 (Bell Telephone Laboratories).

Further developed or anchored was the idea of reaching higher requirements from environmental classifications, for example in the generic US 6,475,009 B2 and the US 6,595,791 B2 , In this document, various adapter plug housing and adapter socket housing are disclosed, which are each suitable for receiving RJ45 plugs or RJ45 sockets.

The invention has the object to provide a further developed version of an adapter plug housing and an adapter socket housing, wherein the embodiment the locking of the male and female parts on the adapter plug housing and the adapter socket housing is optimized.

Preferably, the adapter housing should also meet with simple structural means high mechanical and chemical stresses and requirements and yet be suitable for receiving a variety of plug parts and socket parts.

The invention solves this problem by the subject matter of claim 1.

Advantageous embodiments can be found in the dependent claims.

The created adapter socket and plug parts enable the use of the plug or socket parts even in harsh environments. The term plug or socket part is not meant to be limiting. At the plug or socket part, light-guiding elements, electrical pin and / or socket contacts of various types or e.g. Also be formed elements for pneumatic connector.

The adapter plug and adapter socket parts are further developed such that they are characterized by at least one robust and easy to produce, separate locking hook (also called snap hook arrangement).

Such separately formed locking hooks are compared to those in the US 6,595,791 B2 10, integrally formed Verrieglungshaken optimally adaptable to the application, since they may for example consist of another material - such as a special metal alloy or a plastic or mixed forms of these materials - than the adapter housing itself. Furthermore, exist with regard to the design less constraints than a one-piece molding. In particular, this latching hook is perhaps suitable for a plastic housing, but not for a metal housing, since the required spring properties can not be optimally achieved, for example in zinc die-casting

It is also advantageous that the adapter socket housing can even be provided with two of the separate locking hook arrangements, which allows a particularly firm and secure fit of the socket part in the adapter housing.

According to the preferred variants, the assembly is easy and quick to implement. Due to the design as a plate, the funkionswirksame and space-saving way to produce a cost punched / bent part results.

FIGS. 1 to 20 each show an adapter plug housing 1 or an adapter socket housing 2.

With regard to the adapter plug housing 1, the construction of FIGS. 1 ff preferably dispenses with the undercuts known from the prior art for "deactivating" locking elements on the RJ45 plugs, as known from the prior art documents mentioned above ,

Pins 3 of a bayonet closure are formed on the inner periphery of a locking sleeve 25 which is rotatably guided on the actual adapter plug housing 1.

Sealing elements / rings 27 and possibly further sealing elements ensure a high protection class. The adapter plug housing 1 may be followed by a protective element 29, possibly with a metal or plastic anti-kink sleeve 30, which may be e.g. is screwed onto the connector housing 1 or latched thereto.

In each of the adapter plug housing 1 is a one-piece or multi-piece plug part 34a-d, possibly with subframe 35, 36, 38, 39 (see FIGS. 11 to 14 and 18), in particular - but not only - in the so-called RJ45 standard and other versions, can be used, which will be explained in more detail below.

In each of the adapter socket housing 2, however, is a one- or multi-piece socket part 21a d, 39 (see Fig. 3 and 17 to 19) in particular - but not only - in the so-called RJ45 standard, can be used, which also below in more detail is explained.

• RJ45 (Fig. 11, Fig. 3 - Bezugszeichen 21a, 34a; Fig. 12, Fig. 17, Bezugszeichen 21b, 34b);
• LC-Duplex (Fig. 13; Fig. 18, Bezugszeichen 21c mit Hilfsrahmen 39, 34c mit Hilfsrahmen 35);
• 2SC im Abstand eines SC-RJ (Fig. 14, Fig. 19, Bezugszeichen 21d, 34d mit Hilfsrahmen 36).

One (adapter plug housing 1) or advantageously even two (adapter socket housing 2) in the respective installation space 11a, b inside latching hook assemblies 12 allow each assembly / disassembly of various plug parts and socket parts, eg

• RJ45 (Figures 11, 3 - 21a, 34a, 12, 17, 21b, 34b);
• LC duplex (Figure 13, Figure 18, reference numeral 21c with subframe 39, 34c with subframe 35);
• 2SC at a distance of an SC-RJ (FIGS. 14, 19, reference numerals 21d, 34d with subframe 36).

Conceivable further embodiments of the plug and socket parts (not shown here, for example Firewire, USB, COAX, sensor / actuator contacts, power contacts, etc.).

Like in the US 6,475,009B2 and the US Pat. No. 6,595,791 B1 are the adapter plug housing 1 and the adapter socket housing 2 in the manner of a bayonet connection with pin 3 and receiving and locking grooves 4 coupled (where in each case previously a plug part 34 and a socket part 21, if necessary, with subframe 35, 36, 38, 39 in it were used, which are to be coupled with each other).

The adapter socket housing 2 of Fig. 3 to 7 and 15ff are formed as a flange housing, ie, they have a flange 5 with mounting holes 6, which can be penetrated for example by screws to the flange For example, to attach to a wall at which a implementation is to be realized.

The flange section 5 is adjoined by a housing section 7 which is cylindrical on the outside and which has an external thread 8 in its region adjoining the flange section and then a section with the latching grooves 4 of the bayonet closure.

On the portion with the external thread 8 (see also Figs. 4 and 5), a nut 9 and possibly a sealing ring 10 can be attached, which allow a determination on a passage of a wall.

Thus, an advantageous multi-functional part is created that can alternatively be pushed from behind / inside through the wall and fixed with a central screw or that can be placed on the wall front / outside on the wall and fixed with four screws, so that both installation situations covered with a part can be.

Towards the inside, the adapter socket housing 2 has the receiving space / installation space 11b, which is essentially vertical in cross section, for receiving the socket part 21a (FIG. 3a).

The latching of both the plug parts 34a-d in the adapter plug housing 1 and the socket parts 21a-d in the adapter socket housing 2 by means of a latching hook assembly 12 with at least one (adapter plug housing 1) or preferably two (adapter socket housing 2; as shown here in the figures) or more latching hooks.

According to the embodiment of Figures 1 and 2 and 3 to 5. 6; 8 ff, the latching hook arrangement 12 is formed from a (FIGS. 1, 2, 8 to 14) or from two spring plates 13, 13 ', 14, 24, 24' (FIGS. 3 to 6, 15ff).

The spring plates 24 ', 24 of FIGS. 2 and 6 are made of plastic. Otherwise, metal spring plates 13, 13 ', 14 are used, which may for example consist of a spring metal (for example a spring steel). The spring plates made of plastic can also be locked in a different manner to the adapter housing than the metal plates, in particular without receiving hole, for example by an axial or axial and radial latching / latching arrangement.

These spring plates 13, 13 ', 14 (see, for example, FIGS. 3 and 4 or 15) can each be inserted into recesses 37 of the installation spaces 11a, b, in particular can be inserted.

They each have a receiving hole 15 that serves for its own locking on a latching projection 18 in the adapter socket housing, in conjunction with Unterschiebekanten / slots 20 (see, eg, Fig. 8 and 9), in which edge regions of the spring plates 13, 13th ', 14 are inserted until the locking projections 18 engage in the receiving holes 15. This type of installation is simple and safe. Alternative embodiments of Verrastens the spring plates - especially if they are made of plastic - are conceivable.

An inclined edge 19 (FIG. 4) on the spring plates 13, 13 ', 14 facilitates the insertion of plug and socket parts 34, 21.

Punched and bent projections 17 of the spring plates 13, 13 ', 14 serve as the actual latching hooks 22, 22' for locking the plug-in parts 34 or socket parts 21 to be used.

The spring plates 13, 13 ', 14 may consist of sheet steel.

Alternatively, they could also be made of a different metal or - possibly - even made of plastic.

The metal snap hooks are particularly robust and can be used many times. The spring plates 13, 13 ', 14 can also be easily produced as stamped / bent parts and easy to install.

If the latching hooks 23, 23 'formed from plastic, spring plates 24, 24' may be formed of plastic, which are fixed inside the adapter socket housing 2, in particular latched. (Figures 2 and 6a, b).

If the latching hooks 28, 28 'formed of metal, they could theoretically also be formed on the inside of the adapter socket housing 2 or the adapter plug housing 1 (Fig. 7, 20), if this is feasible tooling technology. These two variants are less expensive than those of FIGS. 1 and 3, but are less preferred because these locking hooks 28, 28 'in metal housing have only poor spring properties and are difficult to produce.

It is also conceivable to use plastic or metal locking springs and to envelop them (not shown here).

To mention as advantageous in terms of the adapter plug housing (1) is still the easy way to attach marks on the different surfaces. As seals O-ring seals are used. There are also depressions 16 which are suitable for receiving markers 26 or the like.

It is also conceivable to provide a groove for receiving a preferably slotted ring 33 for marking. Furthermore, one (of two) larger bevels can be formed in one of the four corners of the installation space 11b (adapter socket housing 2) or 11a (adapter plug housing 1), which advantageously serves as a 180 ° twist protection.
