Abstract

The XLR cable connector comprises a sliding element (2), by means of whose displacement between a retracted and an advanced end position, the XLR cable connector can be converted between a plug and a socket, and that has a first, a second, a third, and a fourth channel (3, 4, 5, 6), a first, a second, and a third contact pin (9, 10, 11) that are received by the first, second, and third channel (3, 4, 5) of the sliding element (2), whereby in the retracted position of the sliding element (2), these contact pins (9, 101, 11) project from the plug-in-side front face (7) of the sliding element (2) and the XLR cable connector with its contact pins (9, 10, 11) can be plugged into contact tubes (20) of a socket (21), and in the advanced end position of the sliding element (2), these contact pins (9, 10, 11) are retracted into the channels (3, 4, 5) of the sliding element (2) and sections of these channels (3, 4, 5) are located on the plug-in-side of the free ends (12) of the contact pins (9, 101, 11), a first, a second, and a third socket contact (15, 16, 17), of which the first and the second socket contacts (15, 16) are arranged in the first and second channel (3, 4) and the third socket contact (17) is arranged in the fourth channel (6), whereby in the advanced end position of the sliding element (2), the socket contacts (15, 16, 17) can be contacted by contact pins (18) of a plug (19) that are inserted into the first, second, and fourth channel (3, 4, 6) of the sliding element (2).

Claims

1. XLR cable connector comprising

a sliding element (2) by means of whose displacement between a retracted and advanced end position, the XLR cable connector can be converted between a plug to connect with an XLR connector constructed as a plug socket (21) and a plug socket to connect with an XLR connector constructed as a plug (19), and that has a first, a second, a third, and a fourth channel (3, 4, 5, 6), which lead to a plug-in-side front face (7) of the sliding element (2) at the corners of an imaginary square, whereby the first and the second channels (3, 4) lie at diagonally opposing corners and the third and fourth channels (5, 6) lie at diagonally opposing corners of the square,

a first, a second, and a third contact pin (9, 10, 11) that are accommodated by a first, second, and third channel (3, 4, 5) of the sliding element (2), whereby in the retracted position of the sliding element (2), these contact pins (9, 10, 11) project from the plug-in-side front face (7) of the sliding element (2) and the XLR cable connector with these contact pins (9, 10, 11) can be inserted into contact tubes (20) of the plug socket (21), and in the advanced end position of the sliding element (2), these contact pins (9, 10, 11) are retracted into the channels (3, 4, 5) of the sliding element (2) and that there are sections of these channels (3, 4, 5) located on the plug-in-side of the free ends (12) of the contact pins (9, 10, 11), and

a first, a second, and a third socket contact (15, 16, 17), of which the first and the second socket contacts (15, 16) are arranged in the first and second channels (3, 4) and the third socket contact (17) is arranged in the fourth channel (6), whereby in the advanced end position of the sliding element (2), the socket contacts (15, 16, 17) can be contacted by the contact pins (18) of the plug (19) that are inserted into the first, second, and fourth channel (3, 4, 6) of the sliding element (2).

2. XLR cable connector according to claim 1, whereby the first and second contact pins (9, 10), in the retracted end position of the sliding element (2), electrically contact the first and second socket contact (15, 16).

3. XLR cable connector according to claim 1, whereby the third contact pin (11) is electrically connected to the third socket contact (17).

4. XLR cable connector according to claim 3, whereby, in the retracted end position of the sliding element (2), the third socket contact (17) arranged in the fourth channel (6) of the sliding element (2) is electrically contacted by a connecting pin (22) projecting into the fourth channel (6).

5. XLR cable connector according to claim 4, whereby for the electrical connection of the third contact pin (11) with the third socket contact (17), there is a connecting element (26) electrically connected on the one hand to the third contact pin (11) and on the other to the connecting pin (22).

6. XLR cable connector according to claim 1, whereby the socket contacts (15, 16, 17) are constructed in a sleeve-shaped manner.

7. XLR cable connector according to claim 1, whereby in the first channel (3) of the sliding element (2), there is arranged for the first contact pin (9) a guide sleeve (23) that has the same construction as the socket contacts (15,16, 17).

8. XLR cable connector according to claim 1, whereby the sliding element (2) is encircled by a sleeve element (1) and is mounted so that it can be displaced by it between its advanced and retracted end position.

9. XLR cable connector according to claim 8, whereby the sliding element (2) is mechanically connected to an operating element (27) arranged outside of the sleeve element (1) through an opening (29) through the sleeve element (1), by means of which the sliding element (2) can be displaced between its advanced and retracted end positions.

10. XLR cable connector according to claim 9, whereby the operating element (27) encircles the sleeve element (1) in a sleeve-shaped manner.

11. XLR cable connector according to claim 8, whereby the contact pins (9, 10, 11) are held by a contact pin carrier (13) inserted into the sleeve element (1).

12. XLR cable connector according to claim 8, whereby an aft housing element (14) is mechanically connected to the end of the sleeve element (1) facing away from the plug-in side.

13. XLR cable connector according to claim 1, whereby the sliding element (2) has a catch (32) with at least one detent (33), whereby the detent, in the advanced end position of the sliding element (2), can engage in a recess in the plug housing of the plug (19), to which the XLR cable connector is connected.

15. XLR cable connector according to claim 7, whereby the sliding element (2) has a centering rib (39) extending in an axial direction that is guided in an axial groove (41) in the sleeve element (1) and that, when plugging in the XLR cable connector, can be inserted into a groove (4) in the plug housing of a plug (19) when the sliding element is in the advanced end position.

16. XLR cable connector according to claim 8, whereby the sliding element (2) in its advanced end position in relation to the sleeve element (1) is lock-engaged.

17. XLR cable connector according to claim 8, whereby the sliding element (2) in its retracted end position in relation to the sleeve element (1) is lock-engaged.

14. XLR cable connector according to claim 14, whereby the at least one detent (33) can be radially displaced in a direction to the longitudinal axis (28) of the XLR cable connector by means of an actuating piece (37) of the operating element (27) through the opening (29) through the sleeve element (1) to open the engage-connection to the plug (19).
