Definitions

• the invention relates to connectors with an actuating slide having camming slots for receiving a guide pin of a complementary connector for the purpose of mating the connectors, and in particular to assuring the actuating slide is properly positioned at the time of mating.
• auxiliary mechanical structure may be an actuating slides or levers. Actuating slides are normally moved in a direction transverse to the plug-in direction of the mating connectors. The actuating slide is normally integrated into one of the connectors and has either a camming groove or a guide pin, the mating connector then includes the other part. When the two connectors are joined together, the actuation of the actuating slide causes the guide pin to move through the camming groove.
• EP 587 174 A2 discloses an electrical connector arrangement, in particular for door connectors in automobiles.
• the connector arrangement has an insulating housing and an actuating slide of conventional U-shaped design.
• the connector housings are brought into the mated position by actuation of the actuating slide.
• the actuating slide has two camming grooves on each side wall of the U-shape.
• the guide pins, which are arranged on the connector housing move in these camming grooves.
• the actuating slide must be in a first position, the entry position, so that the guide pins enter the camming grooves . After the initial joining-together or entry operation, the actuating slide is then moved to a second position, the end position, where the two connectors are interconnected. Since the actuating slide could easily move out of the entry position, it is usually necessary that the actuating slide initially be repositioned prior to the connectors being joined together. This requires an additional work step, which has a disadvantageous effect particularly in the case of conveyor-line assembly.
• EP 501 502 A2 discloses a connector arrangement having a first and a second complementary connector, in which a rotatable plate, on which camming grooves are provided, is provided instead of an actuating slide.
• the connector housing of the first complementary connector, to which the rotatable plate is fastened in a rotatable manner also has a guide slot
• the housing of the second complementary connector has a guide pin which is guided correspondingly during rotation of the rotatable plate through the guide slot and into the camming groove, whereby upon actuation of the lever, the two connectors are joined together.
• JP 62 15 827 A discloses a further connector arrangement incorporating an actuating slide.
• a latch is provided for locking the actuating slide in an entry position where the guide pin can be introduced into the guide groove through the guide slot.
• the latch is designed in the form of latching arms with latching lugs on the actuating slide which are resilient perpendicularly to the plug-in direction. The latching is effected with a corresponding depression in the housing of the connector, which housing accommodates the actuating slide.
• Means for unlocking the latches are provided on the complementary connector, in such a way that when the connectors are joined together, the latches are unlocked and the actuating slide can be moved. Consequently, the actuating slide can only be moved from the entry position when the locking is released by inserting a complementary connector.
• WO97/07567 likewise discloses a connector arrangement with an actuating slide.
• an arm is provided on the housing.
• the arm is resilient in the plug-in direction and engages in a groove in the actuating slide.
• a wedge which interacts with the means for unlocking the actuating slide in the entry position so that the actuating slide can be moved.
• the object of the invention is to specify an electrical connector arrangement with an actuating slide in which inadvertent pushing of the actuating slide from the entry position into the end latching position is prevented in a simple manner.
• the object is achieved by means of an electrical connector having the features of Patent Claim 1.
• Advantageous developments are specified in the subclaims.
• the object achieved by locking the actuating slide in an entry position so that the actuating slide is fixed during transport. It can neither be removed nor pushed further towards the end position from the entry position.
• the insertion of the complementary, second connector releases the actuating slide from the entry position so that the actuating slide can be moved into the end position.
• the locking members are opened in a single work operation, that is during the insertion of the second complementary connector when the two connectors are being joined together at the same time.
• the locking members are designed as an arm on the actuating slide with a latching lug.
• the arm is resilient in the plug-in direction, and prevents the actuating slide from being pushed from the entry position into the end position.
• the resilient arm is bounded on one side by the guide slot. It abuts a wall of the cutout or opening in the housing through which the guide pin is introduced into the camming groove. This resilient arm can be actuated directly by the guide pin of the second connector, by pressure in the plug-in direction.
• the first latching position is the entry position, in which the guide pin can be introduced into the camming groove
• the second position is the end position, in which the two connectors are interconnected.
• the latching members are designed in - 5-
• the housing of the first connector is not constructed with a greater degree of complexity due to the positioning member.
• One embodiment achieves this by widening an opening that is required in any case in order to introduce the guide pin into the camming groove of the actuating slide.
• the latching of the actuating slide in the entry position and in the end position is also provided in those actuating slides which do not have any locking in the entry position.
• a special design of the latching members is not necessary.
• the positioning members are formed by an arm on the actuating slide, which arm is resilient in the plug-in direction and is bounded on one side by the guide slot. Moreover, the production of the actuating slide is not made more difficult by the special configuration. Overall, the solution involved is one which is very simple in terms of production technology.
• Figure 1 shows a cross-section through a housing of a representation of a first connector with an actuating slide and with a phantom indication of a representation of a second connector with pins in the non-connected state; - 6-
• Figure 2 shows a further cross-section of the housing of the first connector with the two connectors in a first position with the actuating slide still locked
• Figure 3 shows a further cross-section of the housing of the first connector with the two connectors in a second position with an indication of movement towards an end position with the actuating slide unlocked.
• a first electrical connector 1 is illustrated in Figure 1.
• the first electrical connector 1 comprises an actuating slide 2, which is commonly of U-shaped design when viewed from above, with a handle 3, which is illustrated in section here, and two side walls 4 extending therefrom. As the connector 1 is shown in sectional form, only one of the side walls 4 can be discerned in Figure 1.
• the side wall 4 has two camming slots 5 and 6.
• the side wall 4 of the actuating slide 2 has a latching lug 7 for establishing an entry position ( Figures 1 and 2) and a latching lug 8 for an end position.
• a resilient arm 9 is additionally provided.
• the resilient arm 9 is bounded on one side by a cutout region 10 of in the side wall 4 of the actuating slide 2 and by edge 22 that defines part of the camming slot 6 on the other side.
• the side wall 4 that is not shown would normally have the same basic construction.
• the first connector 1 has a housing 11, in which the actuating slide 2 is arranged.
• This housing 11 has a latching arm 12 with a latching lug 13 that serves to latch the actuating slide 2 in the entry position and in the end position.
• the latching lug 13 interacts with the complementary latching lugs 7 and 8 on the actuating slide 2.
• the latching arm 12 is resilient in the plug-in direction.
• the housing 11 of the first connector 1 has two openings 14 and 15, which serve to introduce the guide pins 18, 19 of a complementary connector 17 into the camming slots 5, 6 of the actuating slide 2.
• the opening 15 is wider than the opening 14.
• a free end 20 of the resilient arm 9 will run up against an edge 16 of the opening 15 in the entry position. As a result, the actuating slide 2 cannot be displaced towards the end position.
• the resilient arm 9 interlocks the actuating slide 2 by interfering with the edge 16 of the opening 15.
• the plug-in direction of the complementary connector 17 is indicated by an Arrow S.
• the complementary connector 17 is introduced with guide pins 18 and 19 passing through the openings 15 and 14 in the housing 11 of the first connector 1 and entering into the camming slots 5 and 6 of the actuating slide 2.
• the guide pin 19 runs up against edge 22 of the resilient arm 9.
• the resilient arm 9 deflects into the material cutout region 10, as indicated by the arrow F, which also specifies the spring direction.
• the interlocking between the actuating slide 2 and the housing 11 of the first connector 1 is defeated, as illustrated in Figure 3.
• the resilient arm 9 is deflected as a result of the pin 19 running up against edge 22 of the resilient arm 9, which edge 22 is formed by the camming slot 6.
• the actuating slide 2 can now be displaced in the actuating direction, which is indicated by an Arrow B in Figure 3, whereby the two connectors 1, 17 can be brought together in the plug-in direction S.
