Cable connection unit for a connection box
A cable connection unit for a connection box is provided including a cable, which has at least two electrical conductors surrounded by a cable sheath; a cable seal, which radially surrounds the cable sheath; and a cable organizer, in which the at least two electrical conductors are held in a fanned-out arrangement. A matching connection box has at least one receiving region for the cable connection unit, in which the cable seal and the cable organizer can each be placed. A cover of the connection box may then be folded down, whereby the electrical conductors of the cable are pressed into respective insulation displacement contacts of the connection region and thereby electrically contacted.
1 . A cable connection unit for a connection box, the cable connection unit comprising:
a cable having at least two electrical conductors which are surrounded by a cable sheath;
a cable seal radially enclosing the cable sheath, wherein the cable seal is configured to be received in a cable seal socket of the connection box in a form-fitting manner to assist in providing a sealed environment within the connection box; and
a cable manager wherein the at least two electrical conductors are held fanned out.
2 . The cable connection unit according to claim 1 , wherein the cable seal is a one-piece injection-molded part and is fastened to the cable sheath by an injection-molding process.
3 . The cable connection unit according to claim 1 , wherein the cable manager is a one-piece injection-molded part and is fastened to the electrical conductors by an injection-molding process.
4 . The cable connection unit according to claim 1 , wherein the cable manager has a two-part design, wherein the two parts can be interlocked with each other via latches.
5 . The cable connection unit according to claim 1 , wherein the cable manager has two contact openings which each have an essentially rectangular cross-section.
6 . The cable connection unit according to claim 5 , wherein the contact openings are arranged, in the plugging direction, one behind the other and offset relative to one another.
7 . The cable connection unit according to claim 1 , wherein the cable has one cable manager and one cable seal at both ends of the cable.
8 . The cable connection unit according to claim 1 , wherein the cable has a length of no more than three meters.
9 . The cable connection unit according to claim 1 , wherein the cable manager has testing openings, wherein each testing opening is associated with one of the at least two electrical conductor.
10 . A system, comprising:
a connection box; and
a cable connection unit including a cable having at least two electrical conductors which are surrounded by a cable sheath, a cable seal radially enclosing the cable sheath, and a cable manager wherein the at least two electrical conductors are held fanned out,
wherein the connection box has at least one socket region for the cable connection unit in which the cable seal and the cable manager can each be inserted, and
wherein the at least one socket region of the connection box includes a cable seal socket, and the cable seal is configured to be received in the cable seal socket of the connection box in a form-fitting manner to assist in providing a sealed environment within the connection box.
11 . The system according to claim 10 , wherein the socket region of the connection box has insulation displacement contacts.
12 . The system according to claim 11 , wherein two of the insulation displacement contacts correlate with one contact opening of the cable connection unit.
13 . The system according to claim 10 , wherein the connection box has a hinged cover.
14 . The system according to claim 10 , wherein the system has a test device by which a correct electrical contacting between a respective insulation displacement contact and an associated electrical conductor can be checked.
15 . The system according to claim 14 , wherein the test device has contact pins which can each be pushed into a testing opening of the cable manager.
16 . A method for connecting a cable connection unit to a connection box, the method comprising:
inserting a cable seal and a cable manager connected to one end of a cable of the cable connection unit into a connection region of the connection box, including inserting the cable seal of the cable connection unit into a cable seal socket within the connection region of the connection box; and
folding down a cover of the connection box as a result of which electrical conductors of the cable are each pushed into an insulation displacement contact of the connection region and thereby electrically contacted, and whereby the cable seal of the cable connection unit engages the cable seal socket within the connection region of the connection box in a form-fitting manner to assist in providing a sealed environment within the connection box.
17 . The method for connecting a cable connection unit according to claim 16 , wherein a first end of the cable is connected to a first connection box and a second end of the cable is connected to a second connection box.
18 . A method for connecting a cable connection unit to a connection box, the method comprising:
inserting a cable seal and a cable manager connected to one end of a cable of the cable connection unit into a connection region of the connection box, including inserting the cable seal of the cable connection unit into a cable seal socket within the connection region of the connection box such that the cable seal of the cable connection unit at least partially engages the cable seal socket in a form-fitting manner to assist in providing a sealed environment within the connection box; and
pushing the cable manager down with a test device.
