The invention relates to a device for electrically connecting a cable, in particular a plug connection part.

In electrical connectors, a plug element and a

Socket element plugged together, wherein the contact elements of the

Plug element and the female member come into electrical contact with each other and is guided via contact members of the electric current. In case of a pulling force on the cable a

To prevent deterioration of the electrical contact properties, it is known to jam the device with the jacket of the cable, in order to absorb the tensile forces in this way.

The invention is based on the object, a generic

To provide device which has compared to the known devices even further improved performance characteristics, especially when the occurrence of tensile forces or vibrations ensures a permanent electrical connection with low contact resistance. This object is achieved by the device defined in claim 1. Particular embodiments of the invention are defined in the subclaims. In one embodiment, the device has a housing in which a connecting element is arranged, which is mechanically fixed and usually electrically conductive with a soul of the cable is connected, preferably with the inner conductor of the cable. The device further comprises at least one fixing element, by means of which the

Connecting element and thus the soul of the cable is fixed immovably in the housing upon the occurrence of a tensile force by positive engagement. Due to the positive connection, it is not necessary, the fixing forces by clamping, d. H. by static friction forces, but the fixation is independent of frictional forces by the design of the elements. This results over the prior art, the advantage that the creep properties occurring in the course of aging and / or temperature change need not be compensated.

Furthermore, it is advantageous that no clamping forces must be exerted on the cable sheath, which can lead to an undesirable change in the electrical properties. In one embodiment, at least a part of the fixing elements is made of plastic.

In one embodiment, the connecting element is at least

The fixing element may be formed, for example, as an obliquely or in particular transversely to the direction of the tensile force extending bolt, which is inserted into a transverse to the tensile force extending opening in the housing and thereby directly a

Fixation of the connecting element provides.

In one embodiment, the position of the positive engagement of the fixing element in the direction of the tensile force and thus in the axial direction of the device is spaced from the position of the positive engagement of the fixing element on the connecting element. For example, the positive engagement of the fixing element on the connecting element are close to a contact element of the device, in particular close to the connection of the connecting element to the core of the cable,

whereas the positive engagement of the fixing element on the housing is set back, in contrast, in particular on a

Contact member far end of the housing of the device.

In one embodiment, the fixing element is multi-part and the parts are arranged one behind the other in the direction of the tensile force. The several parts are in the direction of the tensile force directly or indirectly below

positive interposition of another element in positive engagement with each other. For example, as another element a

contacting plant are brought to a metallic housing part of the device. The parts of the fixing element can each be sleeve-shaped and receive the cable in its interior. At least a part of the fixing element may be formed as obliquely and in particular transversely to the direction of the tensile force insertable latch.

In one embodiment, the device comprises an elastically deformable spring element, with which the connecting element within the

Housing biased toward the positive engagement with the fixing. This is a backlash-free installation of the

Ensures connecting element in the device. In one direction, the connecting element by the positive engagement with the

Fixing locked, in the opposite direction, the Connecting element against the restoring force of the spring element to be displaced.

In one embodiment, the spring element is in contact with a

Intermediate element. The intermediate element is held by the restoring force of the spring element in contact with the connecting element. The intermediate element may be made of an electrically insulating material, whereby an electrical insulation of the

Connecting element is ensured relative to the housing.

In one embodiment, the intermediate element is at least

in sections sleeve-shaped. The intermediate element may have a radially outwardly projecting shoulder, in particular a flange-like widening, with which the intermediate element in contact with the

Spring element is. The intermediate element may have a radially inwardly projecting shoulder, in particular an annular shoulder, with which the intermediate element is in contact with the connecting element.

The device may comprise a stop means, through which

It is ensured that the spring element is only subjected to maximum pressure of 30%. As a result, a mechanical overload for the spring element is prevented.

In one embodiment, the intermediate element forms a contact protection for an electrical contact element of the device. This can be the

Protruding intermediate element in the insertion direction of the device sleeve-shaped over the contact member. Alternatively or additionally, the

Intermediate element also extend in the opposite direction longer than the connecting element. In one embodiment, the device is designed for electrical voltages in the range of more than 12 V and less than 2400 V, in particular more than 24 V and less than 1000 V and preferably up to an operating voltage of 700 V.

Fig. 3 shows a perspective view of a third

Embodiment of a connector system 201 with a two-pole first connector part 202 and a two-pole second connector part 204, wherein it is in the first

Plug connector 202 is an angled connector, in which the wiring runs perpendicular to the direction of insertion. 4 shows a side view of the connector system 201 of FIG. 3. FIG. 5 shows a perspective view of the connector system 201 in a partially separated state in an enlarged view relative to FIGS. 3 and 4. FIG. The first connector part 202 has a bow-shaped

Actuator 242, with which the two connector parts 202, 204 from the fully assembled in Figs. 3 and 4 state can be converted into a state shown in FIG. 5, in which the pilot contact 218 is either already separated, or at least a complete transfer of the actuating element 242 is separated in a relation to the illustration in Figs. 3 and 4 rotated by 90 ° position, the load contacts 21 2, 214 but are still electrically connected. The actuator 242 is about a preferably integrally formed by the first connector part 202 axle journal 244th

pivotable, whereupon a in the actuator 242, for example, introduced by a groove cam 246 is moved along a arranged on the second connector part 204 guide pin 250 that the first connector part 202 lifts from the second connector part 204.

When the actuating element 242 assumes a position rotated by 90 ° relative to the position in FIG. 3, the pilot contact 218 of the first plug connection element 202 is no longer in electrical

Connection with the pilot contact of the second connector element 204, whereas the load contacts 212, 214 of the first

Plug connection element 202 are still in electrical connection with the load contacts of the second plug connection element 204. The actuator 242 may in its in Figs. 3 and 4

shown first end position and / or in a contrast rotated by 90 ° second end position releasably be locked. By the leverage of the actuator 242 is both the opening and the

Closing the connection between the first and the second

Plug connection part 202, 204 only a small operating force

required. This is particularly advantageous at high temperatures and / or soiling environmental conditions. The first plug connection part 202 and the second plug connection part 204 have mutually corresponding latching means 252, 254, wherein in the exemplary embodiment, the latching means 252 of the first connector part 202 is formed by a recess in a housing wall, in which engages the associated latching means 254 of the second connector part 204 when plugging while locked with the opening. For this purpose, the locking means 254 of the second connector part 204 has a run-on slope, by means of which the locking means 254 is deflected during mating and snaps back as soon as the locking means 254 engages in the opening in the first connector part 202.

After transferring the first connector part 202 from the position shown in FIGS. 3 and 4 in the position shown in FIG. 5 or beyond in a position in which the

Actuator 242 has been pivoted by 90 °, the locking means 254 of the second connector part 204 is in contact with the edge of the locking means 252 forming the opening of the first connector part 202. This completes a complete removal of the first connector part 202 is prevented. Only after, for example by means of a

Screwdriver or other suitable tool, which is for example introduced into the opening and then rotatable, the locking means 254 is brought out of engagement with the locking means 252, the first connector part 202 can be completely removed. The fact that first the actuator 242 must be actuated, and thereby the pilot contact 218 is disconnected while the load contacts 212, 214 are still in communication, and then the locking means 252, 254, for example by means of a tool, alternatively also without tools by hand, disengaged must be brought before the first Plug connector 202 can be completely removed, resulting in practice a time delay of, for example, at least 0.5 or 1 second. This allows a higher-level controller the

Load contacts 21 2, 214 to de-energize after it is signaled by disconnecting the pilot contact 218 that the connection should be disconnected.

Even when plugged together, there is the possibility that initially by attaching the first connector part 202 a

Connection of the load contacts 212, 214 is made, and only by the subsequent pivoting of the actuating element 242 and the

Pilot contact 218 is closed, whereupon a parent

Control line can put the load lines under power. Thus, both the plugging and the release of the electrical connection of the

Load contacts 212, 214 take place without current, whereby the electrical contacts are protected and a permanently reliable electrical connection can be provided.

6 shows a perspective view of an enlarged detail in the region of the latching means 252, 254 in a state in which the first

Plug connector 202 are completely mated with the second connector part 204 and both the load contacts 212, 214 and the pilot contact 218 are closed. FIG. 7 shows an enlarged detail in the region of the latching elements 252, 254 in a state in which the first plug connection part 202 is so far from the second

Plug connector 204 is solved that the pilot contact 218 is disconnected, the load contacts 212, 214 but still connected. The latching element 252 of the first connector part has a first opening portion 256 which is slightly larger than a first portion 258 of the second latching element 254, but smaller than a second portion 260 of the second latching element 254. This results in the position shown in FIG the second section 260 in abutment with the housing 48 of the first connector part 2 and blocks a complete removal of the first connector part 202 from the second connector part 204. Only by a deflection of the second locking element 254,

For example, by means of a tool, the second portion 260 is brought into coincidence with a second, opposite the first opening portion second opening portion 262 of the first locking element 254, which is slightly larger than the second portion 260 of the second locking element 254, so that the first connector part 202th can be removed from the second connector part 204.

formed clamp-shaped, wherein the associated clip in a designated opening 89 (Fig. 1) in the housing 48 in one direction obliquely and in particular transversely to the direction of insertion or to the longitudinal direction of the line 6 can be inserted and thereby locks the fixing element in the housing 48. When a tensile force on the cable 6 occurs, this tensile force is transmitted to the connecting element 78 via the inner conductor 53

transferred in positive engagement with the first part 81 of the

Fixing element, this in turn in positive engagement with the second part 85, and this in turn in positive engagement with the third part 87, wherein the third part 87 is in positive engagement with the housing 48. As a result, a firm connection between the conduit 6 and the housing 48 is provided, which is based only on positive engagement and is independent of frictional forces.

Connecting element 78 addition. In the illustrated embodiment, the intermediate element 91 integrally forms a sleeve-shaped

Guide portion 75 which comes when mating the first and second connector part 2, 4 in abutment against the sleeve-shaped portion 32 (Fig. 1) of the second connector part 4 and is guided. The device 1 1 has a spring element 93, with which the

Connecting element 78 is biased in the housing 48 in the direction of the positive engagement with the fixing element, in the exemplary embodiment, it is biased in the direction of the first part 81 of the fixing. The

Spring element 93 is on the one hand in contact with a radially outwardly projecting shoulder of the intermediate member 91 and on the other hand in contact with a radially inwardly projecting shoulder of the housing 48. By stop means is ensured that the spring element 93 claimed only up to a predetermined value on pressure can be, for example, up to 30% pressure.

The first part 81 of the fixing element has in a portion between the positive engagement with the connecting element 78 and the positive engagement with the second part 85 and the connecting line 83 for the cable shield 57 a locking means 95, with which the first part 81 during assembly the device 1 1 with the intermediate element 91 can be latched. The locking means 95 is formed in the embodiment by a portion with a larger radial dimension, which in a

correspondingly shaped recess in the intermediate element 91 can engage latching. The intermediate element 91 may at its from the

Kontaktorgan of the connector element 10 pointing end have a slotted portion, and at the end of which a

Run-on slope 97 may be arranged to engage the first part 81.
