Definitions

  • the invention relates to an electrical connector assembly, consisting of a trough-shaped accommodating part and a plug part which can be plugged into the latter, having the following features:
  • WO 93/17470 discloses a connector of the generic type. From this publication, it is known to furnish the plug part of the connector with safety ribs. A socket housing can be introduced into the plug part through an insertion opening. In order to secure the socket housing, the surrounding housing can be closed off, for example, by a plugged-on closure plate. It is further known from this publication that the safety ribs can be integrally formed on the plugged-on closure plate. A disadvantage of this arrangement is that it is possible to couple the accommodating part and plug part when the safety plate is not pushed on and the socket housing is not in its end position. This can result in damage to the pins in the accommodating part. Another advantage is provision of the closure plate for securing the socket housing.
  • the object of the invention is to provide a connector which ensures that the socket housing is secured in the plug part in a simple and reliable manner.
  • plug part with means cooperating with the accommodating part to prevent damage to contacts, and ensure correct coupling.
  • a connector assembly comprising a trough-shaped accommodating part and a plug part which can be plugged into the latter, having the following features:
  • socket housing can be latched in the surrounding housing of the plug part without need for a separate cover in a cost-effective and reliable manner.
  • the plug part is prevented from being able to be plugged into the accommodating part at an angle, and thus no damage can be inflicted on the pins in the accommodating part.
  • the arrangement according to the invention ensures that the socket housing must be in its end position before the plugging operation. Moreover, an additional part can be saved.
  • the safety ribs at the two opposite ends have different widths. For example, they are wider on the socket housing than on the surrounding housing. Having wider safety ribs on the socket housing facilitates the handling of this socket housing.
  • a further advantageous feature of a particularly cost-effective version is provision of the latching means on the secondary locking rib of the surrounding housing, which engages with a step or tooth on the housing.
  • FIG 1a shows a side view of a socket housing 21.
  • Sockets for accommodating plug pins, which are held in a corresponding accommodating part, are situated in one or more rows in this socket housing 21.
  • the arrow indicates the push-in direction in which the socket housing 21 is inserted into the surrounding housing 20 of the plug part.
  • the socket housing 21 is essentially a rectangular parallelepiped with longitudinal side surfaces 8 and 9 and transverse side surfaces 10 and 11 (see Figure 2a).
  • Latching lugs 23 are provided on the longitudinal side surfaces 8 and 9.
  • two safety ribs 12 and 13 are provided on the longitudinal side surface, at the end facing the transverse side 10. These safety ribs simultaneously serve as a stop when the socket housing 21 is inserted into the surrounding housing 20 ( Figures 1b and 2b). These safety ribs 12 and 13 allow the socket housing to be handled easily.
  • the surrounding housing 20 has an insertion opening 22 on a transverse side.
  • the socket housing 21 can be pushed into the surrounding housing 20 through this insertion opening 22.
  • the surrounding housing 20 has latching openings 24, in which the latching lugs 23 on the socket housing 21 can latch into place when the latter is pushed into the surrounding housing 20.
  • safety ribs 14 and 15 are provided at each end on the longitudinal side surfaces of the surrounding housing 20. These safety ribs 14 and 15 and the safety ribs 12 and 13 prevent the plug part 2 from being able to be introduced into the accommodating part at an angle and the pins in the latter from being damaged. This principle is disclosed in US Patent US 4,726,791 incorporated herein by reference for all purposes.
  • the safety ribs are designed to have different widths, then they can additionally be used as coding ribs.
  • the safety ribs 12 and 13 are considerably wider than the safety ribs 14 and 15. This prevents the plug from being able to be inserted into the accommodating part in a manner turned through 180°, thereby providing a polarization feature. It can further be discerned that there is provided on the plug part 2 a lever arm having a gearwheel cutout, which would facilitate the joining together of the accommodating part and plug part.
  • Figure 3 depicts a further view of a plug part 2.
  • the socket housing 21 is inserted into the surrounding housing 20.
  • the safety ribs 12 to 15, the transverse sides 10 and 11 as well as the longitudinal sides 8 and 9 and the plugged aspect can be clearly seen.
  • Figure 4 depicts the accommodating part as a pin housing 1.
  • the plug channel 3 having a trough-shaped design can be seen. It has two longitudinal side walls 4 and 5, as well as transverse side walls 6 and 7.
  • Complementary safety grooves 16 to 19 are included that correspond to the safety ribs 12 to 15.
  • the position of the contact pins in the bottom of the channel 3 of this pin housing can clearly be discerned.
  • the central width of the housing is designated by y, while the width of the outer surfaces of the safety ribs is x. It must be ensured that x is greater than y, in order to prevent the pins in the accommodating part from being able to be damaged.
  • the two opposing side walls 4,5 of the accommodating part 1 comprise a toothed rack each for mating the plug and accommodating parts.
  • the lever arm with the gearwheel cutout will be actuated and the teeth will engage with those of the corresponding toothed rack.
  • FIG. 5-9 another embodiment of a plug part is shown at 102 and is shown comprising a surrounding housing 120 and a socket housing 121 for receiving electrical receptacle terminals therein.
  • the plug part 102 is matable to an accommodating part similar to the accommodating part 1 shown in Figure 4 except for certain differences in the connector locking mechanism, whereby the plug part 102 is provided with a resilient latching clip 99 that latches with corresponding shoulders in the accommodating part.
  • the surrounding housing 120 is provided with ribs 112,113 that are used for coding and/or guiding of the plug part with respect to the accommodating part. Although ribs are shown only projecting from one side wall 108, the ribs can of course be provided with the same construction as described in the previous embodiment of Figures 1-4.
  • the embodiment of Figures 5-9 also differs from the previously described embodiment, by the means of securing the socket housing 121 to the surrounding housing 120.
  • the socket housing 121 as generally shown in Figures 5-9 is essentially an existing part comprises an insulative body extending from a terminal receiving end 97 to a mating end 95, bounded by longitudinal side surfaces 109 and end surfaces 110,111.
  • Socket terminal receiving cavities 93 extend from the terminal receiving end 97 through the mating end 97,95 respectively.
  • the cavities 93 are arranged in two rows 91,89 extending in a direction of insertion D of the socket housing 121 into the surrounding housing 120.
  • the housing side walls 109 are penetrated by secondary locking grooves 87 extending in the direction D and traversing the cavities 93 on either side of the housing.
  • the grooves 87 enable access of a secondary locking member in the form of an L-shaped protrusion 85 of the surrounding housing 120 thereinto for engagement behind socket terminals (not shown) mounted in the cavities 93.
  • the L-shaped secondary locking projections 85 extend from and alongside the inside of the surrounding housing side walls 108. Secondary locking of terminals within the cavities 93 thus occurs when the socket housing 121 is slid (mounted) in the direction D into the surrounding housing 120, whereby the L-shaped members 85 slide into the L-shaped grooves 87.
  • the L-shaped secondary locking projection comprises a first horizontal portion 83 and a second vertical portion 81 providing the secondary locking shoulder 79 at a lower free end.
  • the vertical portion 81 engages behind a plurality of wall portions or teeth 77 that bound the socket housing grooves 87 at the side surface 109.
  • the wall portions 77 cooperate with the secondary locking member portion 81 in order to hold the surrounding housing side wall 108 securely against the socket housing side walls 109.
  • the wall portions 77 are separated by recesses 75 that facilitate the moulding procedure of the socket housing, thereby forming teeth.
  • the surrounding housing 120 is provided with an end wall 111 (or transverse side wall) at one end and an open face 110 at the other end for receiving the socket housing 121 therein.
  • latching protrusions 124 are provided on the secondary locking protrusions 85.
  • the latching protrusions 124 are provided on the first or horizontal extension 83 for engaging behind a shoulder 73 of the first wall portion 77 proximate the end 111' of the socket housing 121.
  • the latching protrusions 124 thus provide a very simple means of securing the socket housing 121 in the surrounding housing 120.
  • Figure 6 shows the socket housing 121 almost fully inserted into the surrounding housing 120 whereby the latching protrusion 124 is about to engage the first wall portion 77 as the socket housing end 111' is brought towards the surrounding housing 120 end 111.
  • FIG. 7 shows the socket housing in a fully latched (fully assembled) position within the surrounding housing whereby the latching protrusion 124 has engaged the first wall portion 77.
  • the latching protrusion 124 is provided with a leading end surface 71 that is tapered for smooth ramping over the socket housing tooth 77, and a rearward locking shoulder 69 is provided with an almost vertical but slightly angled locking surface 69. The slight angle or taper 69 enables removal of the socket housing 121 from the surrounding housing when a sufficient force is exerted.
  • a portion of the mating end wall 67 of the surrounding housing can be removed at 65, or a hole 63 through the surrounding housing side wall 108 at the position of the protrusion 124 can be provided.
