Abstract

The casing (10) has a cable wire with ends that are inserted into the casing based on an upper side (11) of the casing, where the ends are inserted in slots (13) formed at a lower side (12) of the casing and are aligned with cutting clamps. The casing is separated in the longitudinal direction such that halves (16, 17) formed by a longitudinal partition are connected with each other at a narrow side running transverse to the longitudinal direction under formation of hinges (19) that are formed as a film hinge, so that the halves are movable by swiveling to open and close the casing.

Description

The invention relates to a core application cap of an electrical connector according to the preamble of claim 1.

An electrical connector has a base module comprising a module housing and a connection device positioned in the module housing, and a core application cap, wherein cable cores of a data cable can be contacted via the core application cap with insulation displacement terminals of the connection device. From the EP 0 901 201 B1 as well as from the US 6,767,241 B1 In each case electrical connectors are known, which include a base module and a core application cap.

In the case of prior art wire-end caps, cable cores of a data cable or ends of the cable cores are insertable from an upper side of the core application cap and can be supplied to a lower side of the core application cap, wherein slots are formed on the underside of the core application cap and receive the ends of the core application cap align to insulation displacement terminals of a connection device of the basic module of the connector so as to ensure a defined electrical contacting of the cable cores with the connecting device during pressing of the core application cap with the basic module. Due to the dimensions of such a core application cap and the associated space limitations, it is usually not possible to introduce a metallic shielding of shielded pairs of cable cores with in the core application cap.

Therefore, the ends of the cable cores must be freed from the paired shield before inserting them into the core application cap. In particular, when data signals are to be transmitted at high data rates or high frequencies, the coupling between the cable cores of different subscribers, which occurs in the absence of shielding of the core pairs, can lead to a deterioration of the data transmission as a result of so-called near-end crosstalk. There is therefore a need for a wire application cap, in the area of which the shielding of wire pairs can be maintained.

The present invention is based on the problem of creating a novel core application cap of an electrical connector.

This problem is solved by a core application cap according to claim 1. According to the invention, the core application cap is partially divided in the longitudinal direction, halves formed by the longitudinal division being connected to one another at a narrow side extending transversely to the longitudinal direction to form a hinge such that the halves can be displaced relative to one another by pivoting to open and to grind the core application cap.

The core application cap according to the invention can be opened and closed by pivoting halves formed by longitudinal division of the core application cap. When opened, the ends of cable cores, including a shield, can be inserted into the core-laying cap. After inserting the cable cores into the core-laying cap together with its shielding, the core-engaging cap can be closed and latched in the closed position. This makes it possible to maintain the paired shielding of the cable cores in the area of the core application cap, thereby effectively minimizing near-end crosstalk and thus improving transmission quality.

The present invention relates to a Aderanlegekappe an electrical connector, namely a data socket for contacting receiving at least one data connector. Such an electrical connector comprises a base module and a core application cap.

Fig. 1 to 5 show different views of a core application cap 10 according to the invention designed as a data connector electrical connector, wherein the core application cap is made of a non-conductive material, in particular of plastic, and has a top 11 and a bottom 12. Starting from the upper side 11, cable cores of a data cable, namely ends of the cable cores, are insertable into the core application cap 10 and can be fed to an underside 12 of the core application cap to insert the ends of the cable cores into slots 13 formed on the underside 12 of the core application cap 10. In the illustrated embodiment, a total of eight slots 13 are made on the bottom 12 so as to accommodate the ends of eight cable wires or the ends of four wire pairs.

The slots 13 align the ends of the cable cores to electrically contact the same when pressing the core application cap 10 to a base module of the electrical connector with insulation displacement terminals of a connector of the base module.

Side walls 14, 15 of the core application cap 10 extending in the longitudinal direction of the core application cap 10 serve as label carriers on the upper side 11 in order to facilitate the insertion of the ends of the cable conductors into the core application cap 10.

The core application cap 10 according to the invention is partially divided or separated, wherein halves 16, 17 formed by the longitudinal division or longitudinal separation are connected to one another in the region of a narrow side extending transversely to the longitudinal direction or of a web extending transversely to the longitudinal direction, namely forming a hinge 19. The two halves 16, 17 of the core application cap 10 can be displaced by pivoting them about the hinge 19 to each other, so as to the core application cap 10 between a closed state (see Fig. 1 to 3 ) and an open state (see 4 and 5 ). The hinge 19 is formed as a film hinge.

The two halves 16, 17 are connected to each other at the transverse to the longitudinal direction web 18, whereby a correct positioning of the two halves 16, 17 is maintained to each other.

One of the halves, namely half 16 in the exemplary embodiment shown, is an anchoring element 20 and the other half, in the exemplary embodiment shown the half 17, is assigned a recess 21. In the closed state, the anchoring element 20 engages in the recess 21, so as to ensure a locking of the two halves 16, 17 of the core application cap 10 in the closed state.

According to the exemplary embodiment shown, the anchoring element 20 and the recess 21 are each assigned to the halves 16, 17 in the longitudinal direction of the core application cap 10, in each case in a projection 22 or 23 positioned approximately in the middle of the core application cap 10. When the core application cap 10 is closed (see Fig. 1 to 3 ), the projections 22, 23 abut each other. Via webs 24 and 25, the projections 22, 23 are connected to the side wall 14 and 15 of the respective half 16 and 17, respectively.

When the lead-in cap 10 is open (see Fig. 4, 5 ) ends of cable cores of a data cable, including the shielding of wire pairs, can be easily inserted into the core application cap. After insertion, the wire application cap 10 is in the closed position (see Fig. 1 to 3 ) by pivoting the halves 14, 15 closed about the hinge 19. With the wire application cap 10 according to the invention, it is possible to maintain the pair shielding in the region of the wire application cap, thus minimizing near-end crosstalk and optimizing the transmission quality.
