Description

The invention relates to a socket module for telecommunications and / or data transmission systems. The receptacle module has a housing with a first printed circuit board fixed therein with cutting contacts as connection means for electrical conductors of a cable, which are accessible from a bottom surface of the housing. In addition, the receptacle module has a plug-in opening for a communicating with the receptacle plug connector, wherein in the plug opening, the electrical contacts are held, which can be contacted with contacts of the plug, and which can be contacted with the cutting contacts of the plug, and contacted with the cutting contacts electrically are.

Such a socket module is known to the applicant from the operational state of the art and has proven itself. Such plug-in socket modules are usually connected to one of the insertion opening opposite or at least the insertion opening remote location of the housing with a cable with electrical conductors. The electrical conductors of the cable can be arranged on a wire distributor, which in turn is in electrical contact with other parts of the socket module. Usually, such a wire distributor is in electrical connection with the cutting contacts of the first printed circuit board. For this purpose, the wire distributor must be supplied to the socket module, in particular the housing, which is time consuming in known in the prior art solutions and requires the use of special tools. This is particularly the case when the receptacle module is to enable excellent transmission characteristics of electrical signals and the like.

Due to the above-mentioned prior art, the present invention seeks to provide a receptacle module of the type mentioned that with excellent transmission characteristics of electrical signals facilitated and made possible without the aid of special tool connection with the electrical conductors of a cable or an am Cable end arranged wire distributor allows, which has only small size and is inexpensive and easy to produce while having a long life.

To solve this problem, the invention proposes a socket module for telecommunications and / or data transmission systems with a housing, fixed therein, first printed circuit board with cutting contacts as connection means for electrical conductors of a cable, which are accessible from a bottom surface of the housing, a plug-in opening for a with the socket connector module communicating plug, wherein in the plug opening, the electrical contacts are held, which are contacted with contacts of the plug, and which are electrically contacted with the cutting contacts, wherein the bottom of the housing is formed open, and the cutting contacts are accessible through the opening, and pass through the bottom of an approximately cuboid receiving part, which is inserted or inserted into the opening, wherein the wire receiving part is open at the bottom of the wire receiving part opposite side and has a pivotable lid part which um a mounted on the housing pivot axis of a first, projecting from the wire receiving part and the housing open position in a wire receiving part and the housing at least partially covering the closed position and pivoted back into the open position or pivoted, wherein the cover part has an approximately U-shaped recess for the implementation of Cable having a arranged at the cable end wire distributor, wherein in the assembly position of the Wire distributor is inserted into the core receiving part and contact the cutting contacts arranged on the wire distributor contacts or the cable ends before.

In such a female connector module, the cable end can be inserted with it or arranged on it vein distributor in a particularly fast and simple manner in the housing of the female connector module and placed in a contact position. In this contact position, the cutting contacts of the first circuit board contact the free, resting on the wire distributor ends of the electrical conductor of a cable. This allows an excellent transmission of electrical signals at the same time extremely low susceptibility to interference from external influences. In addition, such a socket module is particularly compact and thus has only extremely small size, which, for example, the placement of such a socket module in a flush mounting, especially within or as part of a flush mounting box, possible.

When inserting the cable with arranged at the cable end wire distributor in the contact position in which the cutting contacts of the first circuit board with the free conductor ends of the cable in contact, the cable is inserted in the approximately U-shaped recess of the cover part in a first step, wherein the Conductor is arranged in a pre-assembly in front of the housing. Subsequently, the Cover part of the female connector module pivoted in the direction of the housing and thus forcibly guided the wire distributor in the contact position. In this position, the wire distributor is inserted into the wire receiving part, which is inside the housing of the socket module, and the cutting contacts contact the ends of the wires of the cable. The cover part rests against the wire distributor and keeps it in the contact position.

It may be particularly preferably provided that the core receiving part on a side wall has a perforation, which is penetrated by a protruding from the cover part finger, which is positioned in the open position of the cover part in the insertion path of the wire distributor, wherein upon insertion of the wire distributor in the wire receiving part of the wire distributor pivoted the finger and thus the cover part about the pivot axis from the open position at least approximately in the closed position, being arranged in the closed position of the fingers near the bottom of the wire receiving part between the disposed in two rows of cutting contacts.

By arranging such a projecting finger on the cover part, a forced adjustment of the cover part during insertion of the cable end with arranged arranged wire distributor in the wire receiving part of the housing is made possible. When inserting the wire distributor in the wire receiving part and move the cable ends in the contact position with the Cutting contacts thus meets the wire distributor first on the finger of the still pivoted lid part, and causes during insertion of the wire distributor in the wire receiving part pivoting of the cover part about the pivot axis of the housing in an approximate position of the closed position.

In addition, it can be particularly preferably provided that in the assembly position, a cable half-clamp is arranged on the cover part of the wire receiving part, which presses the cable against the base of the U-shaped recess and thus forms a strain relief for the performed through the cover part cable.

Such a cable half-clamp, which is arranged in the assembly position on the cover part and connected thereto, compresses the projecting from the wire distributor cable against the base of the U-shaped recess of the cover part, so that in this area a strain relief for the performed by the cover part cable is formed. In addition, this results in a fixation of the lid part in the closed position. Before attaching the cable half clamp and jamming of the cable carried thus the cover part must be moved completely into the closed position. This is done for example by pressing the lid part against the housing with a corresponding standard tool, such as a combination pliers or a water pump pliers. Such a tool is not considered a special tool, since such a tool is usually always from Fitters also held or carried on site.

It may also be particularly preferred that the cable half clamp has an approximately semicircular clamping region, which complements the U-shaped recess of the cover part to an approximately circular shape and engages with its legs between the legs of the U-shaped recess, wherein the cable half clamp guide means and locking means has, by means of which the cable half clamp in the leg longitudinal direction adjustable and can be fixed on the cover part by means of latching.

By arranged in the region of the legs locking means and guide means, the cable half clamp can be moved manually into a position in which it already exerts slight pressure on the cable and the cable thus pressed against the base of the U-shaped recess of the cover part. Subsequently, the cable half clamp is pressed with the same pliers in the assembly position with which the lid part is fixed to the housing. When pressing with the help of a pair of pliers arranged in the region of the legs locking means engage both the cover part and the cable half-clamp together and lock together to cause a secure hold of the cable half-clamp on the cover part.

It may also be particularly preferred that on or in the cable clamp a leaf spring is held captive as a spring element which cooperates with latching contours on the legs of the U-shaped recess of the cover part, and in that on the leaf spring handling projections are formed, by means of which the leaf spring can be unlocked.

In this solution, a correspondingly shaped leaf spring as spring element, the cable half clamp captive provided by cross, which cooperates with corresponding locking contours on the legs of the U-shaped recess of the cover part and thus the cable half clamp on the cover part and the parts fixed to each other on the housing in the position of use fixed. In addition, the cable half clamp presses the cable passed through against the base of the U-shaped recess of the cover part, so that in this area a strain relief for the cable is effected.

In order to prevent slippage of the cable passed through the U-shaped recess of the cover part and the cable half clamp and at the same time to improve the strain relief, may be particularly preferably provided that the approximately semicircular clamping region of the cable half clamp and the area at and close to the base of the U -shaped recess of the cover part in the direction of the cable projecting mandrels or retaining projections which engage in the position of use in the outer jacket of the cable carried out.

By arranging such mandrels, which engage in the use position in the outer jacket of the cable carried out, the strain relief and thus the positionally secure hold of the cable between the cover part and the cable half clamp is increased or ensured.

In addition, it can be particularly preferably provided that the cable half clamp is arranged on a holding aid, which is connected to the wire distributor and protrudes laterally in a Vormontagelage from this outwards.

By arranging such a holding aid, it is always ensured that the time required for jamming the cable relative to the U-shaped recess of the cover part cable clamp is carried or kept. Thus, for the fitter on site, the number of entrained parts is limited to only one part. The arranged on the holding aid cable half-clamp must be moved if necessary only by the installer from the unneeded Vormontagelage out in a position of use, in which the cable half clamp the cable performed pressed against the base of the U-shaped recess of the lid part and in which the guide means of the cable half clamp the guide means of the cover part are engaged, so that after a subsequent pressing of the cable half clamp with the cover part of this, the cover part in the position secures and the strain relief for the performed cable forms.

Furthermore, it can be particularly preferably provided that the pivot axis is arranged close to or on the side region of the housing near the open bottom.

It can also be provided in particular that the wire receiving part and the wire distributor consist of plastic.

Finally, it can be particularly preferably provided that the housing, the cover part and the cable half clamp made of metal, in particular zinc.

The formation of the housing, the cover part and the cable clamp made of metal allows a particularly effective protection against disturbing influences from the outside and thus increases the shielding located within the housing conductive parts such as the cutting contacts and the free ends of the conductor of the cable. As a result, therefore, the inner part of the housing is particularly shielded and improves the socket module with respect to the transmission characteristics of electrical signals.
