A ball lock 66 is positioned in the center of the connector element 4 and comprises a locking member 68 which is actually displaceable in the connector member 4 and has a portion 70 having small diameter and a portion 72 having larger diameter. Balls 74 are positioned in openings in a portion 76 projecting inwardly from the end wall 46. The balls 74 engage recesses in a part 78 of the displaceable inner portion 62. In the position shown in fig. 1 the portions 76 and 78 are fixed in relation to each other thus providing that the inner portion 62 takes a fixed position in the connector member 4. The portion 72 of the locking member 68 engages the balms in order to retain the balls in the locking position but is displaceable downwardly according to fig. 1 in order to take a position in which the portion 70 is opposite to the balls 74 and the balls can be displaced from engagemeilt in the recesses in the portion 78.

Tune locking member 68 supports a control pin 81 which is adapted to cooperate with the control pin 38 of the control member 32 in order to allow operation of the locking member 68 by means of the electromagnetic device 28.
Like the connector member 2 the connector member 4 is sealed by means of an insulating peg 82 and gaskets 84 and 86.
In the position shown in fig. 1 the contact members 16 and 54 are completely
5 ~.~2~.~53 disconnected from electrical contact with the environment. inn -the connector members 2 and 4 are connected with each other taking a position in josh the end walls 10 and 46 contact each other there does not take place any change of the condition of the contact members from the electrical point of view as a consequence of the connection of -the connector members. The electrical connection between the connector members 2 and 4 is selectively provided by activating the electromagnetic device 28. When the electromagnetic device 28 is activated the control member 32 is displaced downwards according to fig. 1, the enlarged portion 36 of the engagemerlt portion 34 thereby acting on the inner portion 26 which displaces the sleeve portion 20 outwardly from the end wall 10 of the connector member 2 into engagement with the end surface of the sleeve portion 58. Thus, the sleeve portion 20 is projecting from the end wall 10 of the connector member 2 and the sleeve portion 58 is displaced into the end wall 46 of the connector member 4. In the final position the sleeve consisting of the sleeve portions 20 and 58 takes a position in which the electrically conductive portion 22 electrically connects the contact members 16 and 54 with each other. Because of the fact that the sly consisting of the sleeve portions 50 and 58 has an electrically insulating outer surface the sleeve will protect the contact members from electrical contact with the environment also in the position in which the contact members 16 and 54 are electrically connected with each other.
The connector device according to the invention is especially well suited to be used in water at great depths. Thereby the ball lock 66 has the object of obviate the problems which appear because of the fact that there is at great depths required great operating forces for the electromagnetic device 28. Thus, the ball lock 66 provides that the inner portion 62 and thereby the inner portion 26 are locked against displacement during the initial period of the displacement of the control member 32. Not until the control member 32 has moved so far that the locking member 68 has been moved from engagement with the balls 74 through the control pins 38 and 81 the balls 74 can leave their locking position to allow that the control member 32 provides the above described displacement of the inner portions 26 and 62 of the connector members 2 and 4, respectively. It appears from fig. 1 that the-enlarged portion 36 of the engagement portion 34 of the control member 32 is positioned at a distance from the outer surface of the portion of the inner portion 26 which it shall engage so that the engagement does not take place until the locking balls 74 have been displaced from their locking position. Thus, the control member 32 is in the po~sessionof kinetic energy when the displacement of the movable portions of the connector numbers 2 and 4 is initiated, the resistance against

A connector device as claimed in claim 1, in which the contact members are at least partially enclosed by separate portions of a sleeve which is axially displaceable in relation to the contact members, said portions of the sleeve being adapted to engage each other endwise when the connector elements are in their connected position and that the connector element is formed by an electrically conduc-tive portion of one portion of the sleeve.
3. A connector device as claimed in claim 2, in which the outer surface of the sleeve and the end portions of the two portions of the sleeve adapted to engage each other are of electrically insulating material.
4. A connector device as claimed in claim 3, in which sealing elements are positioned at the inner and the outer peripheries of the two portions of the sleeve for sealing the inner connector member against the environment.
5. A connector device as claimed in claim 1, in which at least one of the connector members comprises an outer portion having an inner space in which an inner por-tion is axially displaceable, that the axially displaceable, inner portion supports the electrically conductive connector element and is connected with the electromagnetic device in order to be displaced thereby for operating the connector element.
6. A connector device as claimed in claim 5, in-cluding a locking device for locking the inner portion against displacement during the initial period of the opera-tional movement of the electromagnetic device.
7. A connector device as claimed in claim 1, in-cluding a device for relieving the pressure of a fluid which is enclosed between the connector members when the connector members are connected with each other.
8. A connector device as claimed in claim 7, in which the pressure relief device comprises an expansible chamber connectable with the space between the connector members.
