Definitions

  • the invention is based on a connector according to the preamble of independent claim 1.
  • Such connectors are required in order to connect electrical lines and cables to one another in a reversible manner.
  • a secure electrical and mechanical connection between the plug-in partners must be guaranteed.
  • a permanent mechanical locking of the plug partners is just as important as a complete connection and contacting of internal contacts.
  • Such a type of connector can be electrical as well as optical, pneumatic or hydraulic connectors.
  • the presented invention can be transferred to any type of connector.
  • the DE 10 2012 111 408 B3 shows a locking mechanism for connectors with a mating partner.
  • the locking mechanism has two types of locking means. A primary locking element which is suitable for locking the plug-in partner and a secondary locking element which is suitable for mutual locking with the primary locking element.
  • the secondary locking element locks the primary in the locked state of the locking mechanism, and the primary locking element locks the secondary in the unlocked state.
  • the mechanism is automatically locked by contacting the plug-in partner and unlocked by actuating the secondary locking element - designed as an actuator.
  • the pamphlet EP 1 703 599 A1 Figure 3 shows a connector with coupling detection means and a connector assembly.
  • the pamphlet U.S. 3,201,147 A shows a push-pull connector with a so-called "break away function", ie an emergency release in the event of high tensile forces.
  • the invention is therefore based on the object of presenting a further type of connector in order to expand the variety of such connectors with locking mechanisms.
  • the plug connector should have as few mechanical parts as possible, thereby reducing the reliability and the probability of errors of the device.
  • the existing individual parts of the mechanical locking mechanism should be as robust as possible and have a low susceptibility to errors.
  • the invention is a connector for reversible contacting of electrical, pneumatic, optical or hydraulic lines.
  • the connector is formed by a base body that has a first side and a second side.
  • the first side is designed as a plug-in face and is provided for contacting a mating connector.
  • the second side of the connector is designed as a connection side and is intended to accommodate lines or cables in the connector.
  • the connector also has a plug-in area.
  • the plug-in area is designed to accommodate a mating connector.
  • the plug-in area is the area of the connector in which a mating connector engages with its latching or contact area. This part of the mating connector is usually referred to as the socket or so-called receptacle.
  • the plug-in area of the present invention is used to accommodate such a receptacle.
  • the actuating means of the connector is preferably designed as a sleeve surrounding the base body.
  • the actuating means thus serves as a handle for the connector.
  • the actuating means is movably attached to the base body and can be displaced between a first, closed position and a second, open position.
  • the first, closed position is in the front area facing the first side of the base body, the second, open position of the actuating means being provided in the rear area of the connector facing the second side of the base body.
  • the two positions, the first, closed position and the second, open position simultaneously define the state of the connector.
  • the plug connector is in a closed state in the first, closed position of the actuating means. In this In the closed state, the connector is locked or connected to a mating connector and does not release the connection to the mating connector.
  • the actuating means is in the second, open position, the connector is also in an open state. The locking with a mating connector can be released in this open state.
  • the latching means of the connector is also arranged on the base body. It is provided on the connector in such a way that it can intervene in the plug-in area at least in certain areas. By engaging the locking means in the plug-in area of the connector, the locking means can lock an inserted receptacle of a mating connector.
  • a mating connector or parts of a mating connector are latched preferably via an area of the latching means that engages in a recess in the mating connector or a receptacle of the mating connector in the plug-in area.
  • the latching means can assume two positions: a first, locking position and a second, unlocking position.
  • the first, locked position the latching means engages at least in some areas in the plug-in area of the connector.
  • the locking means is at least partially located in the plug-in area and engages a receptacle there. So it is located in a recess in the receptacle so that it is prevented from moving.
  • the latching means in the first, locking position releases the range of motion of the actuating means.
  • the latching means In the first, locking position, the latching means preferably releases the range of motion of the actuating means in its first, closed position.
  • the actuating means can thus be moved freely from its second, open position and first, closed position without the latching means preventing the actuating means from doing so.
  • the actuating means is designed in such a way that in its first, closed position it locks the latching means in its first, locking position.
  • the latching means can therefore not be moved from the first, locking position into the second, unlocking position when the actuating means is in the first, closed position.
  • a first spring is provided for this purpose, which causes a forced movement of the actuating means in its first, closed position. This means that the actuating means is always forced into the first, closed position by the first spring, as long as the locking means does not prevent it from doing so.
  • the latching means behaves contrary to the plug-in area and the actuating means. In its second, unlocking position, the latching means completely releases the plug-in area of the connector and does not intervene in it.
  • a receptacle or mating connector can move freely in and out of the mating area.
  • the latching means engages in the range of motion of the actuating means in its first, closed position.
  • the actuating means is thus blocked in its second, open position by the latching means, which is located in the second, unlocking position.
  • the actuating means and the locking means thus lock each other, depending on the position in which they are located.
  • the actuating means In its first, closed position, the actuating means blocks a movement of the latching means from its first, locking position into its second, unlocking position.
  • the locking means locks in its second, unlocking position Moving the actuator from its second, open position to its first, closed position.
  • the connector has a locking means which is arranged in the plug-in area of the connector.
  • the locking means can assume a first, locking position and a second, unlocking position.
  • the first, locking position is preferably closer to the first side of the connector and the second, unlocking position is closer to the second side of the connector.
  • a linear movement of the locking means between the two positions would therefore be advantageous.
  • rotating or tilting movements would also be conceivable in other embodiments.
  • the locking means behaves similarly to the latching means as the actuating means. This means that the locking means can be locked in its movement by the locking means.
  • the locking means In its first, locking position, the locking means thus locks the locking means in its movement. In this first, locking position, the locking means is at least partially in the movement space of the latching means in its first, locking position. This means that the locking means cannot be moved from its second, unlocking position into its first, locking position when the locking means is in its first, locking position.
  • a second spring is also provided on the connector, which brings about a forced movement of the locking means into its first, locking position. This means that the locking means is always forced into the first, locking position, unless a greater force prevents it from doing so.
  • a preferred embodiment provides that not only one latching means is provided on the connector, but several latching means are attached.
  • the plurality of latching means are preferably evenly distributed over the circumference of the connector. As a result, when the connector is closed, a force is transmitted evenly to and from the mating connector. This prevents the connector from wedging.
  • the plurality of latching means can also be designed at least partially in one piece. Depending on the design of the latching means, two or more latching means can be designed as one component. This would advantageously reduce the number of individual parts of the connector.
  • the design of the locking means can be different depending on the technical design.
  • Latching means which can be tilted or pivoted between their first, locking position and their second, unlocking position have been shown to be particularly advantageous. But solutions with linearly movable latching means can also be conceivable.
  • the connector expediently has two display means, a first display means and a second display means.
  • the display means are designed to display the status. Depending on which of the display means is visible, a different state of the connector is signaled.
  • the first display means is covered by the actuation means in the second, open position. In the first, closed position, however, the actuating means conceals the second display means. Thus, depending on the position of the actuating means - which defines the state of the connector - the corresponding display means is covered or released.
  • the Figure 1 shows a sectional view of a connector 1 according to the invention along a plug axis in an open state.
  • the side shown on the left forms a first side of the plug connector 1 which is designed as a plug face, that is to say as for contacting with a mating plug connector.
  • the side shown on the right forms a second side of the connector 1 which is designed as a connection side, ie for inserting and contacting a connected cable.
  • the connector 1 shown in this exemplary embodiment is designed as a round connector.
  • the connector 1 is formed from a base body 2 which forms the first side and the second side of the connector.
  • the insulating body provided and received in the interior of the base body 2 as well Contact elements are not shown in this and the following illustrations for the sake of clarity.
  • the base body 2 is surrounded by an actuating means 3.
  • the actuating means 3 is attached to the base body 2 so as to be linearly displaceable along the plug-in axis of the plug connector 1.
  • the actuating means 3 can assume a first, closed position and a second, open position (shown). In the first, closed position, the actuating means 3 is further arranged on the first side of the plug connector 1, ie on the left here. In the second, open position (as shown), the actuating means 3 is further arranged on the second side of the connector 1, ie on the right here, as in FIG Figure 1 to see.
  • This advantageous positioning of the actuating means 3 is mainly used for handling when plugging and unplugging the connector 1 onto or from a mating connector.
  • the actuating means 3 is always positioned in the direction in which the insertion or removal movement is directed. When plugging in the first, closed position in the plugging direction and when removing in the second, open position against the plugging direction. This principle is known as the so-called push-pull principle.
  • the actuating means 3 is assigned a first spring 6.
  • the first spring 6 exerts a constant force on the actuating means 3 and the base body 2. The force is directed in such a way that the actuating means 3 is always forced into its first, closed position. A movement of the actuating means 3 into the second, open position can therefore only take place against the spring force of the first spring 6.
  • latching means 4 In the front region of the plug connector 1 facing the first side, there are two latching means 4 on the base body 2, within the actuating means 3 recorded.
  • the latching means 4 are arranged on the base body 2 such that they can be tilted or pivoted.
  • the latching means 4 can assume two positions: a first, locking position and a second, unlocking position (shown). In the shown, second, unlocking position, the latching means 4 are arranged at least in some areas in the movement area of the actuating means 3.
  • the latching means 4 are tilted radially outward and protrude at least partially in front of the actuating means 3. As a result, the latching means 4 lock the actuating means 3.
  • a movement of the actuating means 3 from its second, open position to its first, closed position is not possible.
  • a locking means 5 is also arranged on the connector 1.
  • the locking means 5 is designed in the form of a ring here and encompasses the base body 2 of the connector 1.
  • the locking means 5 is provided in the front area, on the first side of the connector 1, and is received in a plug-in area 10.
  • the plug area 10 on the first side of the plug connector 1 is designed to receive and mechanically latch a mating plug connector.
  • the so-called receptacle, the socket of the mating connector is inserted and mechanically locked in the plug-in area 10.
  • the locking means 5 is accommodated on the base body 2 so as to be linearly movable between a first, locking position and a second, unlocking position.
  • the first, locking position is in the direction of the first side of the connector 1 and the second, unlocking position in the direction of the second side of the connector 1.
  • first, locking position of the locking means 5 this is positioned in the movement area of the latching means 4.
  • the locking means 5 locks the latching means 4 in their second, unlocking position.
  • a movement of the Latching means 4 from the second, unlocking position into the first, locking position is not possible.
  • the Figure 2 shows a sectional view of a connector 1 according to the invention with a receptacle 20 of a mating connector.
  • the receptacle 20 of the mating connector is the part which is used for the mechanical locking of connector 1 and mating connector.
  • the receptacle 20 is partially inserted into the plug-in area 10 of the connector 1.
  • the connector 1 is in the same open state as in the Figure 1 .
  • the front side of the receptacle 20 contacts the locking means 5 of the connector 1, which is located in the plug-in area 10.
  • the Figure 3 shows a sectional view of a connector 1 according to the invention with a receptacle 20 of a mating connector in a connected, closed state.
  • the receptacle 20 is pushed further into the plug-in area 10 of the connector 1.
  • the locking means 5 has also been moved from its first, locking position into its second, unlocking position.
  • the locking means 5 has been moved against the spring force of the second spring 7.
  • the locking means 5 Since the locking means 5 no longer blocks the movement of the latching means 4 in this position, the latter is moved into its first, locking position.
  • the latching means 4 engages in the plug-in region 10 of the plug connector 1 in such a way that it engages in a recess or groove in the receptacle 20.
  • the actuating means 3 is also moved into its first, closed position. In this position, the actuating means 3 blocks the latching means 4 in its first, locking position. The locking means 4 can therefore no longer release the receptacle 20. A locking of the connector 1 with the mating connector is ensured.
  • the contact areas between the latching means 4 and the actuating means 3 and between the latching means 4 and the receptacle 20 or locking means 5 are designed so that the actuating means 3, receptacle 20 and locking means 5 cause the locking means 4 to move depending on the position.
  • the actuating means 3 exerts a force on the latching means 4, which moves it from its second, unlocking position into its first, locking position.
  • the Figure 4 shows individual locking means 4 in different designs. Thereby are in the Figure 4a two latching means 4 are shown, which are received individually on a connector 1.
  • FIG. 4b An alternative embodiment shows the Figure 4b , in which two locking means 4 are integrally formed.
  • the locking means 4 are over a ring connected. In this embodiment, only one part has to be installed when assembling the connector 1.
  • the Figure 4c shows a locking means 4 as in FIG Figure 4b shown, but in a different production method. While the locking means 4 of the Figures 4a and 4b are designed as solid parts, the locking means 4 is made as a stamped and bent part. Such a production would be economically more profitable for larger quantities.
  • FIG. 5 an inventive connector 1 shown in different states.
  • the connector 1 in FIG Figure 5a the connector 1 is shown in an open state, while the connector 1 in FIG Figure 5b is shown in a closed state.
  • the difference can only be seen in the position of the actuating means 3.
  • a first display means 8 and a second display means 9 are attached to the connector 1.
  • the display means 8, 9 are designed as colored markings on the base body 2. Depending on the position of the actuating means 3, one of the display means 8, 9 becomes visible, while the other display means 9, 8 is covered. A particularly simple identification of the state of the connector 1 is thus possible.
