In FIG. 1 a first or superior connector (superior connector system) 10 is shown as comprising: a first [pin side] male connector, referred to as first male connector 11, and a first [socket side] connector, referred to in short as first female connector 12. The first male connector 11 comprises a housing 13 as well as a male contact support 14. The female connector 12 comprises a female contact support 15 as well as a housing 16. Both the male contact support 14 as well as the female contact support 15 may have the respective contact elements inserted into the respective contact element supports.
Preferably, the male contact support 14 as well as the female contact support 15 comprise a male connector module frame 23 and a female connector module frame 123, respectively. Preferably, different male connector modules 20, 21 and different female connector modules 30, 31 can be inserted into the respective frames. This is shown for the embodiment disclosed in the drawing and which refers to the integration of the RJ45 connector system into a modular connector system.
FIG. 2 is a schematic sectional view of the male contact support 14 together with the male contact support frame 23. The frame 23 comprises (see also FIG. 2A) an upper frame section 24 and a lower frame section 25 as well as a frame side 26. A first male connector module (pin connector module) 21 and a second or a plurality of second connector modules (pin connector module) 20 is/are inserted into said male contact support 14.
FIGS. 3 and 4 disclose that a first female connector module 31 and a plurality of second female connector modules 30 are inserted into the female contact support 15 and the female contact support frame 123, respectively.
The second male connector modules 20, which can be matingly inserted into the second female connector modules 30, form the customary connectors or connections for the power transmission. The first male connector module 21, which can be plugged into the first female connector module 31, preferably serves for the signal transmission and comprises additional contact elements 69.
FIG. 5 through 8 disclose that the first male connector module 21 and the first female connector module 31 form together a connector module 39. The connector module 39 comprises, particularly, a second connector 40 (subordinated connector system 40). The second connector 40, which is also referred to as a signal connector 40, comprises a second male connector 41 (below also called a signal male connector 41) and a second female connector 42 (could also be called a signal female connector 42). The signal male connector 41 is preferably fixedly mounted in the first connector module 21, more specifically in a first male connector module body 22 of the first male connector module 21. The second female connector 42 is located in the first female connector module 31 on a circuit board 51. The circuit board 51 is reciprocally and slidably mounted in the first female connector module 31, i.e. in a first female connector module body 32 of the female connector module 31 in the direction of insertion and in the opposite direction. Preferably, the second connector 40 is a RJ45 connector comprising a RJ45 male connector 41 as well as a RJ45 female connector 42.
The design of the first or superior connector 10, in particular the design of the (first) male connector support 14 and the (first) female connector support 15, each of which is adapted to receive the male connector modules 20, 21 and the female connector modules 30, 31, respectively, causes, because, all components are subject to certain tolerances of manufacture, a certain tolerance in the direction of insertion (“first insertion depth tolerance”) of the first connector 10. This first insertion depth tolerance is larger than the range of the variations of the depth of insertion which is tolerated by the second connector 40, in particular a RJ45 connector. This smaller tolerance in the direction of insertion of the second connector 40 is a characteristic of the second connector 40. This tolerance of the second connector 40 is also called “second insertion depth tolerance”. In FIG. 5 the first male connector module 21 and the first female connector module 31 are shown in a first position wherein all tolerances of manufacture of the first connector 10 are assumed to have the smallest value in the direction of insertion. In this situation, the second male connector 41 is already inserted into the second female connector 42 and provides a contact position in accordance with the standard. Thus, the second connector provides contact in accordance with the standard.
FIG. 6 shows the first male connector module 21 and the first female connector module 31 in a position where all tolerances of manufacture of the connector 10 have been assumed to be maximum (i.e. have the greater value) in the direction of insertion. Here, the first connector module 21 is in complete abutment with the first female module 31. Inasmuch as the second insertion depth tolerance of the second connector 40 cannot compensate the offset—caused by the larger first offset in the direction of insertion due to the insertion depth tolerance—the second or signal female connector 42 is fixedly mounted to the circuit board 51 which is slidably mounted in the first female connector module 31. The circuit board 51 is slidably mounted together with the second female connector 42 of the second connector 40 in the first female connector module 31. The circuit board 51 is subject to a biasing force, preferably the force of a spring. The biasing force is larger than the plug-in force which is required to plug together the second connector 40 contrary to the plug-in direction (direction of insertion) towards a frontal side or front side surface 53 of the first female connector module 31. An abutment surface 102 of the second female connector 42 is in abutment with the inwardly facing frontal side 53. A spring 72, which generates said spring force abuts at a U-shaped support 172 mounted to the first female connector module body 32 and presses against the second female connector 42. The location of the circuit board 51 is selected such that for a maximum plug-in distance (smallest depth of insertion) of the first connector 10, the plug-in connection of the second connector 40 is completely inserted or plugged in, as is shown in FIG. 5. In case that the plug-in distance of the first connector 10 is smaller, (tolerances have the greatest value in the direction of insertion) then the circuit board 51 of second connector 40 is moved against the biasing force in the plug-in direction (direction of insertion) so as to compensate for the tolerance; this occurs when the second connector 40 is completely plugged in as shown in FIG. 6.
To provide for a simple connection, it is possible to locate on the circuit board 51 preferably a second RJ45 female connector 75 (female termination connector). The female termination connector 75 comprises a female termination connector body 76 which supports contact elements 77.
Due to the resilient movement of the circuit board 51 (carrying the second female connector 75), one achieves that the second connector 40 is not damaged and that the first connector system 10 can be completely inserted or plugged in. The arrangement of circuit board 51 and female connector 42 and female connector 75 is also referred to as an intermediate member 100. The intermediate member 100 is reciprocally mounted within the first female connector module body 32 and is biased against the frontal side 53.
For relief of the second male connector 41, in particular for the relief of a detent hook 65 of the RJ45 connector 41, ribs or noses 54 are provided at the first male connector module 21; after completion of the plug-in or insertion operation of the second female connector 40, said ribs 54 abut at the abutment surfaces 102 of the second female connector 42 and, in the case of FIG. 6, the second female connector 42 together with the circuit board 51—i.e. the intermediate member 100—are moved against the bias of the spring 72 in plug-in direction into the first female module 31.
By means of an element 98 mounted in the first male connector module 21, the second male connector 41 is secured against an outward movement contrary to the direction of insertion; in particular for the RJ45 connector 41, the element 98 comes into engagement with the detent hook 65 and presses said detent hook 65 towards the second male connector 41 so as to prevent a detent action or in the inserted condition of the second male connectors 41 in the second female connector 42.
It is also possible to provide a first connector system 10 comprising only one second connector 40, in particular a RJ45 connector 40.
It is also possible to mount the second male connector 41 and/or the second female connector 42 slidably in the direction of insertion.
Moreover, in the first connector further modules, in particular pneumatic modules, can be arranged.
The male and female, respectively connector modules 20, 21, 30 and 31 can be mounted by detent means at the appropriate frame by means of module detent hooks. As an example the module detent hooks 61 are shown in FIGS. 5 to 7.
As is shown, in accordance with the present invention, it is in particular possible to integrate into a modular system C146M (the first or superior connector system 10) a connector (second or subsidiary connector system 40) using an RJ34 connector system. It is possible to readily use standard cables so that a RJ45 connector 41 and a RJ45 female connector 42 are able to mate in the C146 connector. This is made possible by the intermediate member 100 and the two RJ45 female connectors 42, 76.
In a mating C146 system the tolerance of the distances of the frames adapted to receive the RJ45 modules is larger than the admissible plug-in depth tolerance of the RJ45 connector. In accordance with the present invention, the intermediate member 100 is resiliently mounted together with the RJ45 female connectors 42 in the first female connector module body 32, i.e. a frame of the C146 system. As mentioned above, the spring force of the spring 72 is larger than the plug-in force of the RJ45 connector and acts into the direction of insertion. The distance of the RJ45 male connector 41 in the first connector module 21 in the first frame with respect to the RJ45 female connector 32 in the first female connector module body 32 of the second frame 123 of the mating or “plugged-in” C146 system is provided such that also at the largest distance, the frame offers the minimum insertion depth of the RJ45 connector. In case the distance of the frames of the C146 system is too small, then the RJ45 intermediate member 100 with the female connectors 42, 76 resiliently moves such that the RJ45 connector system is not harmed, and at that time the C146 connector system can be completely inserted due to the fact that the nose 54 hits the support surface(s) 102 formed by the frontal surface of the second female connector 42 and moves the female connector body 42 against the spring force of the spring 72 together with the circuit board 51.
The second male connector 41, which is—in the embodiment shown, a RJ45 male connector 41, has to be fixedly held in the connector module body so as to be able to assume or receive the plug-in force.
It is noted that the second male connector 41, which is designed as RJ45 connector 41, is not locked (by detent means) when plugged into the corresponding second female connector 42 which is designed as a RJ45 female connector 42. This is true because of the element 98 which blocks the detent hooks 65. Preferably, element 98 is designed such that the detent hook 65 is, during plug in or insertion, not constantly subject to a load. In accordance with the invention, a sealed housing can be provided for receiving the modules, as shown in FIG. 1. As mentioned, it is also possible that a plurality of modules is arranged adjacent to each other in the housing. The first and second RJ45 female connectors are preferably mounted, as mentioned, on a circuit board.
