The US 2013330957 was first launched in December 2013 on behalf of Tyco Electronics Corp. released. It relates to a connector assembly comprising an outer housing with a front end, has a rear end and a central axis extending therebetween. The outer housing has a passage extending therethrough. The connector assembly also includes a slidable connector disposed in the passage. The sliding connector includes a communication module. The connector assembly also includes a spring frame positioned between the slidable connector and the outer housing. Prior to mating with a mating connector, the spring frame mechanically couples the sliding connector with respect to the outer housing. After the mating connector and the communication module have been communicatively coupled, the spring frame releases the sliding connector from the outer housing so that the sliding connector can move with respect to the outer housing. The spring frame mechanically couples the sliding connector with respect to the mating connector.

Optical connector assemblies are known from the prior art which include a first connector part and a second connector part which can be mated. In some applications, at least one of the connector parts is mounted on a circuit board in order to further process the optical signal. A ferrule, which terminates at least one optical fiber of at least one connector part, is spring-loaded and displaceably mounted so that a contact pressure between the two ferrules of the respective connector parts is kept in a paired state. In most applications, the spring is designed as a spiral spring which is arranged coaxially around the optical fiber (s) and in the interior of a housing of the respective connector part. The spring is therefore usually located behind the ferrule around the optical fiber (s) and inside the connector housing. Screws and, for example, a support plate are known means of securing and anchoring the spring to the housing.

Because of the complicated structure and the number of components, the connector parts known from the prior art are comparatively expensive. In addition, assembling the individual connector parts (such as attaching the ferrule and spring to the connector housing) is often difficult and time consuming. This is particularly the case when the spring has to be replaced if there are compatibility problems between the dimensional tolerances of the spring and / or the force of the spring and the respective connector parts.

In particular, the assembly of individual connector parts, when the housing is already attached to a line card or a printed circuit board, is unfavorable due to the limited space available on such panels on which the connector part is surrounded by several components, among other things.

Summary of the invention

It is an object of the invention to provide an optical connector assembly having connector parts that are easier to assemble and operate.

An optical connector assembly according to the invention comprises a first connector part and a second connector part which can be connected to the first connector part in a mating direction. The first connector part includes a housing that has an opening extending in the mating direction through the housing from a front end to a rear end of the first connector part. The front end is the end of the connector part which, in the mated state, is directed towards the second connector part. The rear end is usually the end of the first connector part from which the ferrule is inserted. The first connector part further comprises a ferrule arrangement which, in a mounted position of the first connector part, is arranged in the opening and is displaceable in the mating direction in relation to the housing. The ferrule arrangement comprises a ferrule which terminates at least one optical fiber. During mating with the second connector part, the ferrule assembly is displaced relative to the housing in the direction of the rear end of the first connector part against the force of a spring of a spring assembly which interconnects the housing and the ferrule assembly. In an anchored state of the spring arrangement, the ferrule arrangement, which is arranged in the opening of the housing, is pressed against the housing by the at least one spring. Thus, the movement of the ferrule arrangement is restricted on the one hand in the mating direction towards the front end of the first connector part and on the other hand the ferrule arrangement is spring-loaded mounted in the mating direction towards the rear end of the connector part. The housing and ferrule assembly may include connection means for attaching or securing the spring assembly in relation to the housing or other element.

Compared to the connector parts known from the prior art, the spring arrangement according to the invention is easily accessible from outside the first connector part, ie without complicated disassembly. Preferably, the spring arrangement is arranged outside and adjacent to the housing, e.g. B. by at least partially along an outside of the Housing extends. The spring arrangement comprises at least one spring. The spring arrangement can further comprise other parts in order to transmit the force of the spring and / or to support it. The at least one spring can be a spiral spring and / or a leg spring and / or a leaf spring. In a variant, the spring arrangement is laterally displaced in relation to the ferrule arrangement or to the general extent of the light guide cable which is interconnected with the ferrule arrangement in order to avoid certain problems which are known from the prior art.

Good results can be achieved if the spring arrangement is based on one or more leg springs, which provides good clearance and easy accessibility from the outside, as will be further described below. The leg spring comprises a first leg, a second leg and a winding section arranged between them, which connects the first leg and the second leg to one another. The leg spring is provided in order to exert a restoring force between the ferrule arrangement and the housing when the ferrule arrangement is displaced to the rear in relation to the housing. The first leg is normally used to be connected to the housing together and the second leg is normally used to be connected to the ferrule assembly, or vice versa. For a uniform force equalization on the ferrule, the spring arrangement can comprise two leg springs which are connected to one another via a clamp. The two legs of the different leg springs can also merge continuously and form the bracket. The end sections of the first and / or the second leg can point towards one another. If the spring arrangement comprises more than one winding section, the winding sections are preferably arranged coaxially, but spaced from one another by a distance.

Depending on the application, the ferrule arrangement can comprise a ferrule plunger which is guided in the opening of the housing such that it can be displaced in the pairing direction. The ferrule plunger is used to transmit the force of the spring to the ferrule. Advantageously, the ferrule plunger is arranged behind the ferrule in relation to the pairing direction (in the pairing direction at the rear end of the first connector part) and comprises connecting means in order to be connected together with the spring arrangement. The connecting means of the ferrule plunger can, for example, be at least one recess in which a section of the spring, such as the end section of the first and second legs or, if appropriate, of the clamp can be inserted and secured. As appropriate, the ferrule assembly may include a pin holder to hold and align the ferrule guide pins. In the mounted position, the guide pins can extend through and out of a front end of the ferrule in order to connect them together with a corresponding ferrule of the second connector part. If a ferrule plunger is present, the pin holder is arranged between the ferrule plunger and the ferrule. Alternatively, the guide pins can also be located in the ferrule of the second connector part, while the ferrule of the first connector part has corresponding guide holes. The pin holder and ferrule plunger can also be formed as a single integral component that incorporates the various functions of the two parts.

The following method steps are usually carried out for assembling a preferred variant of a first connector part: Providing a housing which comprises an opening which extends in a mating direction through the housing from the front end to the rear end of the housing. Providing a ferrule assembly comprising a ferrule terminating at least one optical fiber. Providing a spring arrangement comprising at least one spring. These steps are followed by the insertion of the ferrule arrangement into the opening of the housing and the subsequent connection of the spring arrangement together with the housing and the ferrule arrangement from the outside, so that the ferrule arrangement can be displaced against the force of the spring.

For a quick and easy connection of the spring arrangement together with the housing, the first connector part, as described above, can comprise a tension member in order to mount the spring of the spring arrangement between the ferrule arrangement and the housing and to put it under tension during the assembly of the spring arrangement. Thus, the tension member includes retention means for engaging a portion of the spring assembly during assembly. In a preferred variant, the holding means is a recess or a hook or the like, to which the respective spring section can initially be attached in a less or not at all tensioned state of the spring. To assemble the spring, the tension member or the holding means with the spring attached to it can be displaced or pivoted around an axis relative to the housing or the ferrule arrangement, so that the spring is anchored in a controlled manner during the displacement. In a preferred variant, the housing comprises a recess in order to receive and secure the tension member in the anchored state of the spring. The recess is preferably arranged symmetrically to the ferrule group on an outside of the housing, such as the upper side. Depending on the application, the first connector part be suitable to be interconnected with a circuit board, in particular a line card. For this purpose, the first connector part can comprise fastening means for interconnecting the first connector part with the plate or card. In addition, the second connector part can be adapted to be interconnected with a circuit board such as a backplane.
