Abstract

The device includes a first connector housing (7) in which end portions of a number of optical fibres (1) are secured and a second connector housing (11) in which a corresponding number of optical elements to be connected to the fibres, for example end portions of further optical fibres (3), is secured. After the connection has been established, the two connector housings (7, 11) are detachably coupled by means of a locking device which includes a first locking portion (17) which is provided at the first end (16) of a lever (15) provided on the first connector housing (7) and a second locking portion (18) which cooperates with the first locking portion and which is provided on the second connector housing (11). In order to establish also an electrical connection between pairs of conductors (35, 41), an electrical contact member (27, 37) is provided near each of the two locking portions (17, 19). In the locked condition, these contact members (27, 37) are electrically interconnected; they are separated from one another upon unlocking.

Claims

1. A device for optical connection of a number of optical fibres to a corresponding number of optical elements, including a first connector housing in which end portions of the optical fibres are secured and a second connector housing in which the optical elements are secured, which two connector housings, after the connection has been established, are detachably coupled by means of at least one locking device comprising a first locking portion which is situated at a first end of a lever provided on the first connector housing and a second locking portion which cooperates with the first locking portion and which is provided on the second connector housing, characterized in that near each of the two locking portions there is provided an electrical contact member, the said contact members being electrically interconnected in the locked condition and being separated from one another upon unlocking.

2. A device a claimed in claim 1, characterized in that at least one of the two locking portions is made of an electrically insulating material, the locking portions being formed by at least one hook-shaped projection near the first end of the lever and at least one protrusion on the second connector housing, respectively, said projection having to pass the protrusion when the connection is established, the height of the protrusion being such that the electrical contact members are separated from one another during this passage.

3. A device as claimed in claim 1 or 2, characterized in that the optical elements are end portions of further optical fibres.

4. A device as claimed in claim 3, characterized in that the first connector housing is constructed as an optical plug and the second connector housing is constructed as an optical socket.

5. An optical connector comprising:

a first connector housing for accommodating an end of an optical fiber;

a second connector housing for accommodating an optical element to be optically coupled to the fiber in the first connector housing;

a lever pivotally arranged on the first connector housing, said lever having a first end with a projection;

a protrusion on the second connector housing arranged to be engaged by the projection on the lever when the first and second housings are connected;

a first electrical contact arranged on the first end of the lever; and

a second electrical contact on the second connector housing arranged to be contacted by the first electrical contact when the first and second housings are connected and when the projection on the lever engages the protrusion on the second connector housing.

6. An optical connector as claimed in claim 5, characterized in that:

the first connector housing has an outer surface;

the lever is pivotable about an axis substantially parallel to a tangent to the outer surface of the first connector housing; and

the projection on the lever is arranged to slide over the protrusion on the second connector housing in order to connect the first and second housings.
