• the invention relates to a connector having a housing having a channel extending from a first end of the housing to a second end of the housing, wherein at the first end a connection piece and at the second end a connection geometry is provided, wherein inside the Channel is provided a heating zone, wherein between the heating zone and the second end, a heat-conducting element is arranged, wherein the heat-conducting element has a heat-emitting portion which is formed as a cylinder sleeve which surrounds an inner space.
• a heating zone which can heat the channel or the fluid flowing through the channel.
• a heating element is provided, which is guided through the connection piece and can extend into the line connected to the connection piece.
• a power supply for example an electrical power supply
• WO 2009/013342 A2 shows a conduit connector and a media conduit, both of which can be heated by a heating wire wound around inner conduit walls.
• a heatable media line is known.
• a heating wire runs surrounded by a thermally conductive molding within the media line.
• the heating wire can be led out of the media line through a separate connection housing.
• the object of the invention is to provide a connector of the type mentioned, which allows rapid heating of the fluid line or the fluid to be transported in the fluid line.
• a connector with a housing having a channel extending from a first end of the housing to a second end of the housing, wherein at the first end a connection piece and at the second end a connection geometry is provided, wherein a heating zone is provided in the interior of the channel, wherein a heat-conducting element is arranged between the heating zone and the second end, wherein the heat-conducting element has a heat-dissipating section, which is designed as a cylinder sleeve which surrounds an interior, provided that the cylinder sleeve has a circumferential direction having closed peripheral wall.
• a heat-conducting element is provided for heating the fluid volume, which is in heat-conducting contact with the heating zone.
• the heat-conducting element absorbs the heat from the heating zone and directs it into the heat-dissipating section.
• already flowing into the channel fluid can be heated before it flows into the heating zone.
• connection with the heating zone is thus a very large area available, in which the fluid can be heated, so that an effective heating of the fluid can be achieved.
• the entire existing in the connector fluid is heated so that, for example, a urea present in the connector can be heated quickly to a flowable temperature.
• the heat-conducting element has a heat-dissipating portion formed as a cylinder sleeve surrounding an internal space in which the channel is partially formed.
• the cylinder sleeve can be based at least partially on a circular cylinder. But there are any other cross sections possible. Since the channel extends through the cylinder sleeve and is completely enclosed by the circumferentially closed peripheral wall of this, the fluid flowing through the cylinder sleeve is completely heated. The area over which heat can be transferred is kept as large as possible.
• the heat-conducting element may have a fastening portion which is inserted into the channel.
• the attachment portion is used to secure the heat conduction member in the housing. For this purpose, it is fixed in the channel.
• the heat-conducting element has an outer dimension along its length that is at most as large as the inner dimension of the channel.
• the heat conducting element is clamped in the channel.
• the heat-conducting element is sufficiently secured in the housing. Other fasteners are not required.
• the heat-conducting element can assume the temperature of the heating element, which is generally higher than the temperature of the liquid in the heating zone at a certain distance from the heating element. This further improves the heat transfer from the heating element into the channel.
• the heat-conducting element is connected by clamping to the heating element. If the heat conducting element is connected by clamping with the heating element, then it is applied to the heating element with a certain voltage. This improves the heat transfer between the heating element and the heat conducting element.
• a ramp element may be arranged in the channel, along which the heating element is led out of the channel, wherein the heat-conducting element has a recess which receives the ramp element. It is then possible to guide the heat-conducting element around the ramp element so that, despite the ramp element, it can be inserted relatively far into the heating zone and can preferably be clamped to the heating element.
• the housing has a particular movable locking geometry and the heat-conducting element protrudes into a region in which the locking geometry is arranged.
• the locking geometry is used, for example, to hold a nozzle and release it, possibly after a movement of the locking geometry, so that the connector can be removed from the nozzle. Since the locking geometry acts on the connecting piece, it is ensured that the heat-conducting element can protrude into the interior of the connecting piece when it projects into the area in which the locking geometry is arranged. It is then possible to ensure the heating of the interior of the nozzle even when a sealing arrangement is arranged at a different position and the heat-conducting element does not extend into the region of the sealing arrangement. In such a locking geometry, for example, it is not possible to arrange a heater, such as a heating wire, outside of the housing.

• the second end 16 is connected to a reservoir or to a pipeline connected to the reservoir. connected portion and the first end 14 is fluidly connected to a consumer or connected to the consumer line section.
• a heating zone 26 is provided, in which, as can be seen in Figure 2, a heating element 28 is provided.
• the heating element 28 in the present case is a flexible heating element which has at least one heating conductor embedded in an extruded plastic material. Preferably, two heating conductors are provided, which are connected to one another at an end remote from the connector 10, so that an electrical connection is necessary only at one end of the heating element 28.
• the heating element 28 is flexible and bendable. However, it has a certain inherent rigidity, so that the heating element 28, when a line section (with heating element therein) is pushed onto the connecting piece 18, the heating element 28 can be inserted into the connecting piece 18.
• the heating element 28 must be led out of the connector 2 in order to produce electrical connections, not shown, via which the desired heating power can be introduced into the heating element 28.
• the connector 10 has a heating element outlet channel 30 whose longitudinal axis 32 is at an angle ⁇ to the longitudinal axis 34 of the connector 10.
