Definitions

  • the present invention relates to a jack socket for amplifiers, speakers, electrical musical instruments and. Like., Which has a socket part for the insertion and mounting of an electrical plug element and at least two electrical contacts which can be brought into engagement with the plug element.
  • the devices can be made ready for operation by suitable connections to power sources by inserting plug elements into the jack sockets provided on the devices.
  • Jack sockets of the type described in the introduction are in use in many embodiments. They usually have a socket part and a housing part adjoining the socket part.
  • the socket part has a round inner hole for receiving a round electrical plug element, which comes into contact in the housing part with two contact clamps for mono plugs and three contact clamps for stereo plugs, with a corresponding recess on the plug element or projecting sections on the contact clamps for locking between the plug element and contact terminals is reached.
  • the contact terminals are connected to suitable conductor sections that lead out of the jack socket. Jack sockets without a corresponding housing part are also known.
  • the present invention has for its object to provide a jack socket of the type described above, which is protected against unauthorized use.
  • a jack socket of the specified type in that it has a lockable and removable blocking element inserted into the socket part, which prevents unauthorized insertion of an electrical plug element into the socket.
  • the solution according to the invention thus provides for the corresponding jack socket to be blocked by an inserted element in such a way that a corresponding electrical plug element can no longer be inserted.
  • the associated device on which the jack socket is arranged can thus no longer be connected to an electrical power source or to another device, so that the device can no longer be put into operation by an unauthorized person.
  • the lockable and removable blocking element inserted into the socket part can be unlocked by an authorized person and then removed from the socket part, so that a corresponding plug element can be reinserted into the jack socket by an authorized person. It is understood that only authorized persons have suitable means for unlocking the blocking element.
  • the blocking element can preferably be locked and unlocked by means of a key.
  • the blocking element In order to protect the device provided with the jack socket from unauthorized use, the blocking element is inserted into the socket part and locked there by actuating the key. If the device is to be released for use again, the key is unlocked again, after which the blocking element can be pulled out of the socket part.
  • the blocking element has an actuating element and a locking element which can be actuated by the actuating element and which, in the actuated state, extends to a position radially outside the bore of the socket part and thereby prevents the blocking element from being pulled out.
  • the locking which can be achieved with the blocking element therefore comes about in that, by actuating the actuating element, the locking element is brought into a position radially outside the bore of the socket part, which prevents the blocking element from being pulled out of the socket part. Therefore, if the actuating element is actuated with the aid of the key, the locking element moves into the position radially outside the bore of the socket part, and the locked state of the blocking element is reached.
  • the key can then be removed so that the jack socket is blocked for unauthorized persons.
  • the actuating element is returned to its starting position, as a result of which the locking element comes into its position within the bore of the socket part.
  • the blocking element can now be pulled out of the jack socket.
  • actuation can also include the insertion of a key or a comparable element.
  • the corresponding unlocking takes place by pulling out the key.
  • the locking element is moved so far radially out of the socket part that the blocking element cannot be pulled out by certain manipulations by unauthorized persons. Since in such jacks the actual socket part with a corresponding bore is relatively short and behind it is the housing with the plug-in elements, the locking element behind the bore of the socket part in the housing can be moved radially outwards, so that it is attempted to pull out the blocking element against the step formed between the housing and the bore, making it impossible to pull it out.
  • the actuating element is arranged on the cylinder of a lock which can be actuated with the key and can be rotated by turning the key from an initial position into an actuating position, while the locking element is arranged on the lock housing.
  • the lock cylinder and thus the actuating element is rotated into the actuating position in which the locking element, which is arranged on the lock housing, is moved radially outward.
  • the key is turned in the opposite direction.
  • the locking element is designed as a sleeve element starting from the lock housing and at least partially expandable, in which the rod-shaped actuating element is located.
  • the expansion of the sleeve element takes place preferably via a rotation of the actuating element; however, it can also be done, for example, by inserting the actuating element into the sleeve element.
  • the locking element can comprise a bendable or bendable tab, which is bent or bent out by the actuating element and thus brought into a position radially outside the bore of the socket part.
  • the actuating element and / or the locking element expediently has a corresponding thickening, by means of whose contact with the locking element or actuating element the locking element is moved radially outward.
  • the thickening is again moved into a position in which it no longer moves or bends, bends or spreads the locking element outward, so that the blocking element can be pulled out of the jack socket.
  • the blocking element designed according to the invention is preferably only partially inserted into the jack socket in the locked state; rather, it is essentially based on this. A particularly simple and convenient actuation of the blocking element is hereby achieved.
  • the lock housing is preferably located outside the socket part and abuts one end against the front socket part end, while the locking and the actuating element are inserted into the socket part and extend through this into the housing (if present).
  • the actuating element and locking element are designed as a single element and have a rotatable elongate element, on the latter a blocking section rotatable behind a projecting section of the jack socket is formed at the front end.
  • the elongated element is preferably also actuated using a key which is inserted into a suitable cylinder lock. By turning the lock cylinder, the elongated element is rotated, so that the blocking section comes into its blocking position engaging behind a projecting section of the jack socket.
  • the procedure for reversing the blocking element is reversed, ie the key is turned in the opposite direction, whereby the blocking section is unscrewed from its blocking position. In this starting position of the blocking section, the blocking element can be pulled out of the jack socket again.
  • the elongated element is preferably guided through a tube that can be inserted into the jack socket.
  • the tube ensures that the blocking element assumes a fixed central position in the jack socket, so that the blocking section automatically comes into the correct position.
  • This blocking section is preferably designed as an eccentrically arranged disc at the front end of the elongate element. In the non-blocking position, the disk assumes an approximately central position with respect to the tube and is rotated out of this position for locking. It is understood that the elongate element is arranged eccentrically with respect to the tube and the lock cylinder.
  • the jack 1 shown in vertical longitudinal section in FIG. 1 has an approximately rectangular housing 3 made of plastic and a socket part 2 which extends to the right in the figure and is provided with an external thread and which is also made of plastic.
  • the inside of the socket part has a circular bore in section, which is lined with metal.
  • a conventional electrical plug-in element (not shown) is introduced into this bore, which has a corresponding section which is circular in section and which is adapted to the bore of the socket part 2 and which is inserted Condition of the plug element is recorded by this.
  • the plug element has a tip at the front end and an annular groove just behind it.
  • two metallic contact terminals 5 arranged in the housing 3, which run obliquely inwards, are bent radially outwards and snap back due to their spring action into the groove provided on the plug element, so that on the one hand the plug element latches in the jack socket and on the other hand an electrical line between the plug element and contact terminals 5 is produced.
  • the plug element is pulled out, the resistance exerted by the contact terminals 5 is overcome, and these return to their starting position.
  • the contact terminals 5 are connected via suitable metal webs to the connection terminals 6 projecting from the housing 3.
  • FIGS. 2 and 3 show the schematic structure of a first embodiment of a blocking element 4 which can be inserted into the jack socket if there is no plug element in it in order to protect the socket against unauthorized use.
  • the blocking element 4 is lock-shaped and comprises an approximately cylindrical lock housing 7, in which a lock cylinder 8 is rotatably arranged.
  • the lock cylinder is actuated using a key 9 which can be inserted into a suitable key opening in the lock cylinder. If the key bit is in the lock cylinder, the lock cylinder and a rod-shaped actuating element 11 arranged in an extension thereof and connected to the lock cylinder can be rotated by turning the key.
  • the actuating element 11 extends through a front opening in the lock housing 7 and is surrounded by a sleeve-shaped locking element 10 fastened to the lock housing 7.
  • the sleeve-shaped locking element 10 is in its left in the figure End section slotted.
  • the resulting lower part of the locking element is shorter than the associated upper part.
  • a thickening 12 extends into the free space formed thereby at the front end of the rod-shaped actuating element.
  • Figure 3 shows that the lock cylinder and thus the rod-shaped actuating element 11 is rotated by turning the key.
  • the thickening 12 reaches an upper position and thereby presses the upper part of the resilient, sleeve-shaped tapering element 10 upwards.
  • FIG. 1 shows, in this position the upper part of the tapering element 10 is in a position radially outside of the bore of the socket part 2, so that the blocking element 4 can no longer be removed from the jack socket without turning back the lock cylinder.
  • FIG. 4 shows a further embodiment of a blocking element 4. Apart from the actuating element and locking element, this has the same structure as the blocking element shown in FIGS. 1 to 3. A description of identical parts is therefore omitted. The mode of operation is also corresponding.
  • the rod-shaped actuating element 20 has a recess 23 in its front section, in which a thickened portion 22 of a sleeve-shaped locking element 21 rests in the non-actuated state.
  • this sleeve-shaped locking element 21 also has a slot in its front area, as a result of which a resilient, bendable section is produced.
  • the actuating element 20 is rotated by 1800 so that the thickening 22 migrates out of the recess 23 and now lies against the smooth opposite surface of the actuating element 20 is coming.
  • the upper section of the locking element 21 is bent out, again into a position radially outside the bore of the socket part, so that in this embodiment it is also not possible to pull the blocking element 4 out of the jack socket in this position.
  • FIG. 5 shows a further embodiment of the invention, in which case only the blocking element is also shown without an associated jack socket.
  • the blocking element 30 has a suitable cylinder lock with a lock cylinder which can be actuated in a known manner using a key 9.
  • an elongated element 32 connected to the lock cylinder and eccentrically arranged thereon is rotated, at the front end of which a blocking section 33 in the form of a disc, which is in turn eccentrically arranged on the elongated element, is arranged.
  • the elongated element 32 extends through a tube 31 arranged in the middle of the lock, which serves as a guiding and fixing element of the blocking element in the jack socket.
  • the left representation in FIG. 5 shows the blocking element in the unlocked state.
  • the blocking element is inserted into the jack socket, the tube 31 coming into contact with corresponding sections of the jack socket.
  • the key 9 is turned, whereby the disk-shaped blocking section 33 gets into the position shown in the right-hand illustration of FIG. 5, in which it engages behind a corresponding inwardly projecting section of the jack socket.
  • the blocking element can no longer be removed from the jack socket.
  • the reverse process takes place to remove the blocking element, ie the key is removed rotated in the opposite direction, whereby the disk-shaped blocking section 33 returns to its starting position shown on the left in FIG.
  • FIG. 6 shows a last embodiment of the invention. Again, only the blocking element is shown without an associated jack socket.
  • the blocking element 30 has a suitable cylinder lock with a lock cylinder, which can be actuated in a known manner using a key 9.
  • an elongate actuating element 32 which is connected to the lock cylinder and is arranged thereon, is rotated, the front end of which is provided with a projection arranged eccentrically to the axis.
  • This projection is rotatably arranged in a correspondingly adapted recess of a pin 35 which is guided in a corresponding bore in a tube 31 arranged in the center of the lock, for example made of plastic.
  • the elongated element 32 also extends centrally in a corresponding cavity of the tube 31.
  • the elongated element 32 is rotated and the pin 35 is thus moved up and down over the eccentrically arranged projection depending on the direction of rotation.
  • the pin In the open position, the pin is located completely inside the tube 31, while in the closed or blocked position it protrudes from the tube and prevents the blocking element from being pulled out.
