The cable lug device includes a pin element for fixing a cable; and a socket element, in which the pin element is insertable and which is configured to be connected to an external conductor, in particular an external cable or wire. The pin element is adapted to exit the socket element upon a predefined threshold value of force acting on the pin element and/or the socket element. Further, a pin element for a cable lug device, a socket element for a cable lug device and a method for mounting a cable lug device are described. ## Claims ### Claim 1 A connector device comprising: a body including a first channel for receiving a cable, and a second channel perpendicular to the first channel for receiving an external conductor, the first channel opening into the second channel; and a connector device comprising: a pin element; a socket element; wherein the pin element includes: a fixing part for fixing the cable to the pin element; and a pinning part; wherein the socket element includes: a receiving part configured for receiving the pinning part of the pin element of the cable lug device; a palm part for electrically connecting the socket element to the external conductor, wherein the receiving part of the socket element includes at least one first receiving receptacle; at least one elastic element held between at least one elastic element receptacle of the pin element and a first receiving receptacle of the socket element, the at least one elastic element electrically connecting the pin element to the socket element of the connector device and/or the at least one elastic element for holding the pin element in the socket element of the connector device, wherein the at least one first receiving receptacle is placed and adapted to hold the at least one elastic element together with the at least one elastic element receptacle of the pin element; and a fastening device for fastening the pin element to the socket element, wherein the fastening device is held in a second receiving receptacle of the socket element; and wherein the fastening device is a fastening device with shear off function, wherein the pin element exits the socket element upon a predefined threshold value of force acting on the pin element and/or the socket element, wherein the pin element and the receiving part are arranged in the first channel, and the palm part extends from the first channel into the second channel. ### Claim 2 (depends on 1) The connector device according to claim 1, wherein the cable lug is adapted to provide an electrical contact from the cable fixed to a fixing part of the pin element via a palm part of the socket element to an external conductor being in contact with the palm part of the socket element. ### Claim 3 (depends on 1) The connector device according to claim 1, wherein the connector device is a device for connecting two or more wires or cables with each other. ### Claim 4 (depends on 1) The connector device according to claim 1, wherein the connector device is a cable lug device for high voltage applications, in particular for high voltage applications with a voltage equal to or greater than 1 kV. ### Claim 5 (depends on 1) The connector device according to claim 1, wherein the socket part has a loop part, an eye, or a hole for electrically contacting an external conductor. ### Claim 6 A method for mounting a connector device, the connector device having: a body including a first channel for receiving a cable, and a second channel perpendicular to the first channel for receiving an external conductor, the first channel opening into the second channel; and an emergency break cable lug device, which comprises: a pin element, wherein the pin element includes: a fixing part for fixing the cable to the pin element; and a pinning part; a socket element, wherein the socket element includes: a receiving part configured for receiving the pinning part of the pin element of the cable lug device; a palm part for electrically connecting the socket element to the external conductor, wherein the receiving part of the socket element includes at least one first receiving receptacle; at least one elastic element held between at least one elastic element receptacle of the pin element and a first receiving receptacle of the socket element, the at least one elastic element electrically connecting the pin element to the socket element of the emergency break cable lug device and/or the at least one elastic element for holding the pin element in the socket element of the emergency break cable lug device, wherein the at least one first receiving receptacle is placed and adapted to hold the at least one elastic element together with the at least one elastic element receptacle of the pin element; and a fastening device for fastening the pin element to the socket element, wherein the fastening device is held in a second receiving receptacle of the socket element; and wherein the fastening device is a fastening device with shear off function, wherein the pin element exits the socket element upon a predefined threshold value of force acting on the pin element and/or the socket element, the method comprising: inserting the socket element into the second channel so that the palm part extends from the first channel into the second channel; and inserting the pin element through the first channel into the socket element for forming the emergency break cable lug device. ### Claim 7 (depends on 6) The method according to claim 6, further comprising connecting at least a first cable and a second cable to each other with the cable lug device, wherein the method further includes fixing the first cable to a fixing part of the pin element and aligning a palm part of the socket element to the second cable, after the pin element has been inserted in the socket element.
