Definitions

  • the invention relates to an electrical connector assembly including a housing for socket contacts and a complementary housing for plug contacts, wherein a first connector housing comprises a plurality of engaging means for engaging corresponding engaging means of a complementary second connector housing.
  • Electrical connectors typically include a socket housing and a plug housing which are adapted to be engaged so as to connect corresponding electrical contacts.
  • the insertion force needed to connect the two housings depends on the number of contacts included in the housings. Further, depending on the number of contacts and on their specific use, connectors of the type described above are normally engaged according to different designs so as to increase the stability of the connector assembly.
  • the plug housing is inserted into the socket housing without the help of additional means and the two housings are kept in their final position by latch projections.
  • the housings are engaged with the help of actuation means so as to overcome the friction between the mating contacts.
  • Such connectors may be also used in cases where one of the housings is fixed and not easily accessible so that direct insertion becomes more difficult.
  • a common design for a connector of this type provides a connector assembly wherein the mating plug and socket connector housings are engaged using a lever.
  • a connector assembly which includes an actuating lever is described in the European patent EP 0 977 324 B1 .
  • This document describes a connector including two housings wherein one housing pivotally supports a lever adapted to connect the mating housings by rotating to a final position.
  • Another example of an electrical connector assembly actuated by a lever is described in the documents US 2002/0022391 A1 and WO 2008/062389 A2 .
  • a further design for a connector assembly that is often used in the automotive sector is provided with an actuation slide means as described in EP 1 396 910 A1 .
  • an actuation slide means is arranged on the moveable housing of a connector assembly and is displaceable in a direction transverse to the direction of engagement of the two housings. Accordingly, the moveable housing is moved towards a fixed housing by displacing the slide means transversely with respect to the direction of movement of the moveable housing.
  • a similar arrangement is also described in the United States patent 5,618,194 .
  • each of the connector arrangements described above is especially designed for a particular use.
  • the design allowing direct insertion of the plug housing into the socket housing is indeed useful if the available space is limited but can only be used if the connector can be easily reached by the user and if its configuration allows the user to grab the moveable housing for connecting and disconnecting the contacts. Further, such a design is preferably used when the number of contacts in the connector is limited.
  • designs including the lever or the actuation slide means are very practical when only a small portion of the moveable housing of the connector can be reached by the user, making it difficult to grab the moveable housing for extraction. Further, these designs are preferred in the case that the plug and socket housings include a large number of contacts.
  • the problem underlying the present invention is to provide a modular connector with a versatile and flexible design wherein standard connector housings are adapted to be engaged according to different mating designs, so that the connector can be used for different applications and in different sectors according to the user needs and wishes.
  • a first connector housing for use in an electrical connector assembly includes a first and a second engaging member arranged on the walls of the first connector housing. Further, at least one pivot means is arranged on at least one of the walls of the first connector housing so as to support a third engaging member for pivot movement. Each of said engaging members is adapted to be mated with a corresponding engaging member on a complementary second connector housing and is adapted to lock the two mating housings when the contacts are connected. Since the first connector housing can be engaged with the second connector housing by using at least one of the engaging means according to the user's needs, it is possible to choose the engaging design which is more appropriate to the particular application.
  • the electrical connector assembly including the plug and socket housings according to the invention is particularly advantageous compared to the usual electrical connectors. Indeed, while the housings of standard electrical connectors are adapted to be mated according to one standard design only, the connector housing according to the present invention is adapted to be engaged according to all the most common mating designs, thereby being more flexible.
  • the first engaging means includes at least two guiding elements adapted to be engaged with corresponding cam profiles of an actuation slide means for moving the complementary second connector housing towards the first connector housing when the actuation slide means is moved to a final position.
  • the engaging means may comprise one or more guide pins.
  • the first connector housing may be further provided with one or more locking openings arranged on the walls of the first connector housing. Said openings are adapted to receive at least one locking bolt included in the second connector housing so as to firmly interlock the first and second connector housings when the first connector housing and the complementary second connector housing are completely connected.
  • an actuation lever may be mounted on the pivot means arranged on the walls of the first connector housing as an example of third engaging member. This allows to provide a contact housing which can be connected with its mating housing using a frontal actuation lever.
  • the actuation lever may include a first and a second lever portions adapted to be supported by the pivot means arranged on opposing walls of the first connector housing and joined by a bridge element.
  • the possibility of applying an engaging lever to the first connector housing allows to have a mating design which is particularly stable and adapted to engage an electrical connector including a large number of contacts.
  • the actuation lever may include at least one first guide groove.
  • Said guide grove is adapted to engage a corresponding first engaging pivot included in the complementary second connector housing. This has the effect that, when the lever is pivoted to its final position, the second housing is driven into the first housing so as to fully connect the contacts in both the first and second housings of the electrical connector.
  • the first and second lever portions may further include at least one second guide groove adapted to engage a corresponding second engaging pivot included in the first connector housing for pulling the first connector housing into the complementary second connector housing in a direction along the mating direction of the electrical connector.
  • the second engaging pivot is vertically aligned with the first engaging pivot included in the complementary second connector housing. Since the second engaging pivot of the first connector housing and the first engaging pivot of the second connector housing are positioned above each other and engage the first and second guide grooves, a rotation of the actuating lever towards a front face of the first housing will pull the first connector housing and the complementary second connector housing together so as to reduce the tolerance chain for the terminal contact overlap. Further, since the first and second engaging pivots are firmly closed by the first and second guide grooves of the actuating lever, once the lever is in its final position the system is very stable against external forces that could open the connection by accident.
  • one of the walls of the first connector housing includes a resilient latch member which may be engaged with a mating latch member of the bridge element of the actuating lever. This allows to fix the first connector housing to the complementary second connector housing, thereby avoiding that the contacts in the housings are accidentally disconnected.
  • the first connector housing may further include contact receiving cavities for receiving power and signal contacts, wherein said contact receiving cavities are symmetrically disposed with respect to one of the middle axis of a face of the first connector housing. Since the contact receiving cavities are disposed symmetrically, the available space in the connector housing can be better organized and the overall dimensions of the housing can be reduced while the number of contacts is increased.
  • the contacts are generally signal contacts and power contacts and, in a particular embodiment, are fixed to the first connector housing by means of at least one power contact lock and at least one signal contact lock. Said contact locks are adapted to be inserted in corresponding receiving holes formed on the walls of the housing.
  • the second engaging pivot of the first housing can be formed on a contact lock. If the contact lock is adapted to be inserted in a wall of the first housing in a vertical position with respect to the first engaging pivot of the complementary second connector housing, the second engaging pivot can be vertically aligned with the first engaging pivot included in the complementary second connector housing, thereby increasing the stability of the system when the actuating lever is in its final position. Further, since the actuating lever can be rotated to its final position only if the contact lock including the second engaging pivot is correctly and completely inserted in the corresponding receiving holes, situations in which the first housing is connected to the second housing while the contacts are not firmly interlocked to the first housing are avoided. Again, once the engaging lever is in its final position, it will secure the contact locks of the first housing in their position so as to avoid accidental side wards movement of the same.
  • the first housing may exhibit two opposing recesses on the inner face of at least two of the walls of the first connector housing. Said recesses are adapted to receive corresponding protrusions formed on the complementary second housing.
  • a second connector housing which includes a first, a second and a third engaging means.
  • the second and third engaging means for the second connector housing can be interchangeably mounted on walls of the second housing.
  • Each of the above mentioned engaging means can be engaged with a corresponding engaging means arranged on a complementary first connector housing.
  • the second connector housing is finally adapted to be engaged with a first connector housing by using at least one of said engaging means.
  • the second connector housing comprises an actuation slide means.
  • Two guide grooves are respectively included on two opposing sides of the actuation slide means for engaging with corresponding engaging means of the complementary second connector housing.
  • at least two cam profiles are included in two opposing walls of the actuation slide means and extend in a direction transverse to a direction of mating of the electrical connector.
  • the guide grooves are adapted to be engaged with guide profiles of the second housing and the at least two cam profiles are adapted to be engaged with a corresponding guide pin on the first housing.
  • the first housing is moved towards the second housing when the actuation slide means is moved to its final position.
  • the connector can be locked by sliding the actuation slide means along the connector in a direction transverse to the mating direction of the electrical connector. This provides the advantage that a large force can be applied to the housings so as to easily connect electrical connectors including a high number of contacts.
  • this solution also has the advantage that the space needed for actuating the slide means is reduced compared with the space needed for actuating an engaging lever.
  • the at least one first and second guide profiles of the second housing exhibit at least one resilient latch member which operate with at least one corresponding mating latch member on the actuation slide means for locking said actuation slide means in a final position. This allows to increase the stability of the whole electrical connector assembly and to avoid that the contacts in the housings can be accidentally disconnected.
  • the second engaging means for the second connector housing is adapted to be inserted in at least one second socket receiving hole formed on at least one of the walls of the second connector housing.
  • the second engaging means for the second connector housing includes at least one locking bolt adapted to be engaged with the locking opening of the complementary first connector housing.
  • the second housing may be connected to the first housing by means of an actuating lever.
  • the first engaging pivot is adapted to be engaged with corresponding guide grooves formed in the first and second lever portion of the engaging lever and, once the connection between the two counter-parts is established, the second connector housing can be moved towards the complementary first connector housing by rotating the engaging lever to its final position.
  • the second housing includes contact receiving cavities for receiving power and signal contacts.
  • Said contact receiving cavities are symmetrically disposed with respect to one of the middle axis of a connector face of the second connector housing. Since the contact receiving cavities are disposed symmetrically, the available space in the connector housing can be better organized and the overall dimensions of the housing can be reduced while the number of contacts is increased.
  • the contacts may be fixed to the second connector housing by the second or third engaging means.
  • the second connector housing may further include at least one additional receiving hole for receiving at least one additional contact lock for fixing the contacts in the second connector housing.
  • the second and third engaging means of the second connector housing may advantageously have a protrusion adapted to slide into the recesses of at least two walls of the complementary first connector housing for guiding the insertion into said complementary first connector housing.
  • An electrical connector according to the present invention comprises the first and second housings described above. Since the two housings of the electrical connector according to the invention are provided with a plurality of engaging means, it is possible to use said electrical connector in different situations by using at least one of the provided engaging members. This can be done without modifying the design of the connector and without having to purchase additional components.

  • the signal contacts are fixed to the plug housing 100 by means of the signal contact lock 108 inserted into the corresponding receiving holes 107 formed on the rear wall 102 of the plug housing 100.
  • the socket connector housing 300 is partially inserted into the plug housing 100 and the actuation lever 210 is partially engaged with its counterpart on the socket housing 300.
  • the counterpart of the actuation lever 210 is the engaging pivot 511 on the second socket power contact lock 500.
  • the engaging pivot 511 is inserted into the curved guide groove 214 of the actuating lever 210 through the aperture 215 and from this starting position, the actuation lever 210 can be rotated along the direction 20 towards a final position so as to completely lock the plug housing 100 with the socket housing 300.
  • the engaging pivot 511 formed on the second socket power contact lock 500 slides into the locking opening 112 through the inserting channel 130, formed on the protrusions 110 of the side walls 303 of the socket housing 300. Since the actuation lever 210 locks with pivots on the second socket power contact locks 500 on both sides of the socket connector housing 300, the connector is pulled to a final position by means of said second socket power contact locks 500, thereby reducing the tolerance chain for the terminal overlap.
  • Figure 10 shows an embodiment of the present invention according to the actuating lever design of figure 9 wherein the actuation lever 210 is locked in its final position. From the figure, it is possible to see how the resilient latch member 105 of the plug housing 100 locks the actuation lever 210 by engaging the grip portion 216 with its arrow-shaped latch portion 106.
  • FIG. 11 An embodiment of the electrical connector actuated by the actuating lever 220 is depicted in figure 11 .
  • the counterpart of the actuation lever 220 is the engaging pivot 511 on the second socket power contact lock 500.
  • the engaging pivot 511 is adapted to be inserted into the curved guide groove 214 of the actuating lever 220.

  • the cam portions 120 of the power contact locks 115 slide into the cam profiles 218 of the actuation lever 220. Accordingly, the actuation lever 220 pulls the plug housing 100 and the socket housing 300 together by means of the engaging pivots 511 on the second socket power contact lock 500 and the cam portions 120 on the power contact locks 115.
  • This solution allows to further reduce the tolerance chains for the terminal contact overlap.
  • the engaging pivot 511 slides through the inserting channel 130 until it is completely inserted into the locking opening 112.
  • the actuation lever 220 also keeps the power contact locks 115 in position, thereby avoiding that the power contact locks 115 are unintentionally moved from the final position.
  • Figure 12 shows a transparent perspective view of the fully connected electrical connector using the actuation lever 220. From this figure it is possible to see the relative position of the first engaging pivot 511 and the cam portion 120. According to this embodiment, the engaging pivot 511 of the socket housing 300 and the cam portion 120 of the plug housing 100 are vertically aligned, thereby being in line with the locking force. Since the actuating lever 220 cooperates with the engaging pivots 511 on the socket connector housing 300 and the engaging pivots or cam portions 120 on the plug housing 100 and the pivots 511 and 120 are vertically aligned and in line with the locking force, the stability of the fully connected connector can be increased.
  • Figure 14 illustrates a situation in which the power contact lock 115 is not completely inserted into the plug housing 100.
  • the use of the power contact lock 115 in combination with the actuation lever 220 provides the further advantage that, when the contact lock 115 is not completely inserted into the corresponding receiving openings 107 of the plug housing 100, the actuation lever 220 cannot reach its final position, and a situation wherein the electrical connector is connected while the power contacts of the plug housing 100 are not fixed to the housing itself is avoided.
  • Figure 15 shows the electrical connector according to the invention, wherein the connection is actuated by an actuation slide means 600.
  • the legs 620 of actuation slide means 600 can be pushed along the front and rear walls of the connector.
  • the control slots 621 integrally molded on the inner side of each leg 620 of the actuation slide means 600 will engage the corresponding guiding rails 304 formed on the socket housing 300.
  • the first of the three control grooves 622 molded on the inner face of each leg 620 of the actuation slide means 600 will mate the first guiding pin 104 of the plug housing 100.
  • the second and third control grooves 622 will mate the corresponding second and third guiding pins 104 on the plug housing 100, thereby causing the plug housing 100 to move towards the socket housing 300 in the direction of mating of the electrical connector until the contacts in the plug housing 100 are fully connected with the contacts in the socket housing 300.
  • the actuation slide means 600 can be further releasably latched in an end position by means of the two resilient latch portions 312 formed on the guiding rails 304 and the two locking spikes 313.
  • the resilient latch portions 312 on the guiding rails 304 will move towards the plug housing 100 when the actuation slide means 600 is engaged with the guiding rail 304 so as to allow the actuation slide means 600 to slide into its final position.
  • the resilient latch portions 312 of the guiding rails 304 will resiliently return to their original position, thereby locking the actuation slide means 600 in its final position.
  • the locking spikes 313 provided on the guiding rails 304 contribute to increase the stability of the fully connected connector.
  • the socket connector housing 300 includes the second socket power contact locks 500 but it may alternatively include the first socket power contact locks 400. If the first socket power contact locks 400 are used, the locking bolts 411 will fit into the locking openings 112 on the side walls 103 of the plug housing 100 when the actuation slide means 600 is in its final position, thereby increasing the stability of the connector.
  • An example of an electrical connector fully connected by means of an actuation slide means 600 is shown in figure 16 .
  • Figure 17 shows a top view of a face 700 of the electrical connector according to the invention. From this figure, it is possible to see the disposition of cavities for receiving contacts.
  • the electrical connector is designed for receiving 30 contacts. Accordingly, 20 contact cavities 710 adapted to receive 20 signal contacts (not shown) are disposed in a central position of the connector face 700 and are arranged on five rows. The 20 signal contacts can support a wire with a section between 0.35 and 1.5 mm 2 . On the right and left sides of the signal contacts receiving cavities 710 are disposed two groups of four AMP MCP (multiple contact point) contact receiving cavities 720, which are an example of first power contact cavities.
  • AMP MCP multiple contact point
  • Two further AMP MCP contact receiving cavities 721 are respectively disposed on the right and left sides of the two groups of 4 AMP MCP contact receiving cavities 720 and are an example of second power contact cavities.
  • all the terminal cavities are symmetrically disposed with respect to one of a middle axis 701 of the electrical connector. This disposition allows to organize the available space in the connector face 700, thereby reducing the dimensions of the connector itself.
  • the electrical connector according to the invention can receive a 30-way connection and its overall dimension is essentially the same as the dimension of a 20-way connector of the same type.
  • a new electrical connector is provided, which can be connected using a plurality of mating designs according to the user needs and the available space.
  • the invention uses a standard housing design for socket and plug housings, on which it is possible to assemble different engaging means like a lever and a slide keeping the same housing configuration.
  • the same housing design can be used for a direct insertion connection.
  • the connector assembly according to the invention has the advantage that a standardization at the customer production side can be obtained, thereby causing a reduction of the investments. Furthermore, since the electrical connector according to the invention can replace a plurality of standard connectors currently used in the industrial production, e.g. in the automotive sector, this provides the further advantage of simplifying the management of the part numbers. Indeed, the electrical connector according to the present invention, which is associated with only one part number, replaces a plurality of standard connectors, each of which is associated with one part number.
