Definitions

  • the invention relates to a multi-pole electrical connector according to the preamble of claim 1.
  • Such an electrical connector is known from DE 4131768 AI.
  • the connector consists of a housing and a locking device.
  • Contact part chambers arranged in the housing are equipped in the plug-in direction with contact parts which are first locked by means of elastic fingers molded onto the inner walls of the contact part chambers.
  • the final locking of the contact parts is carried out by a locking device which can be inserted transversely to the direction of insertion of the contact parts into an opening in the housing.
  • the contact part chambers end in the plug area on a perforated front wall of the housing.
  • Each contact part chamber is assigned two openings in the front wall.
  • a plug-in opening serves to receive counter-contact parts, and an unlocking opening enables the finger to be deflected by means of a blade-like tool to release the contact part.
  • the design of the plug-in area is based on the spray-technical possibilities in such small constructions.
  • the insertion opening and the unlocking opening are arranged in such a way that no undercuts occur.
  • the injection mold or its cores are simple.
  • the plug opening adapted to the cross section of the mating contact part apparently protects the contact part in the contact part chamber from improper manipulation.
  • the adjacent insertion opening is larger than necessary due to the general injection molding conditions and is unprotected and constantly accessible both before and after the connector has been fitted and secondly locked. As a result, there is a risk of damage the contact parts and the fingers during assembly and also after assembly at the installation site.
  • the invention has for its object to design an electrical connector with a double locking of the contact parts according to the preamble of claim 1 so that the housing can be populated with contact parts and is protected in the plug-in area against damage and that their implementation in terms of production and assembly technology with little Effort is possible.
  • the subject of claim 1 has the advantage that the connection of a locking comb and a cover plate to a one-piece preassembled push element protects the contact part chambers and consequently also the contact parts against improper access.
  • the separation of the cover plate from the insulating material housing enables the proven second locking mechanism to be retained and allows the insulating material housing to be fitted both from the front and from the rear.
  • the one-piece assignment of the cover plate and the locking comb ensures a consistent sequence of movements. Only when the correct second locking position has been reached can the connection to the corresponding mating contact parts be made by aligning the contact parts to the plug openings.
  • the connector By coupling the cover plate to the locking comb, the connector consists of only two individual parts. The extraordinarily high ones, especially in such small applications Tool costs decrease.
  • the contact part chambers can be realized in a straightforward manner without undercuts which are complex in terms of injection molding technology, so that the injection core arrangement and its removal from the mold are extremely simple.
  • cover plate and the locking comb are connected to each other via crossbars, which gives the push element sufficient inherent stability.
  • a corresponding profile opening receives the crossbars and the locking comb of the push element and serves as a guide channel.
  • Additional guide means on the edges of the cover plate facilitate assembly and increase the accuracy of fit.
  • Both the assembly and the locking position of the push element are defined by complementary locking means that can be distinguished visually and audibly.
  • a longitudinal slot is formed in the cover plate, which is aligned with the profile opening in the plug area, so that a pin of the mating plug can be inserted.
  • the pin serves to secure the first locking and can additionally act as coding or centering the mating connector.
  • the longitudinal slot also has inwardly directed edges which thus completely encapsulate the contact part chambers.
  • the axial alignment of the connector and the mating connector takes place via their complementary outer shapes, so that incorrect connection is not possible. However, an initial tilting, ie angled attachment, is possible within maximum tolerance ranges.
  • Such connector systems can be equipped with individual contact parts, which must engage their counter-contact parts in front of the majority of the contact parts, so that a defined circuit state is created in advance. To prevent these protruding contact parts from kinking when they are brought together at an angle, recesses are provided in the corresponding plug-in openings in the cover plate.
  • Figure 1 is a view of the front of a bare connector with inserted in an insulating housing slide element in the locked position.
  • Figure 2 is a side view of the connector of Figure 1.
  • FIG. 3 shows a further side view of the connector according to FIG. 1 in the longitudinal direction L.
  • 4 shows a longitudinal section of the connector according to line AA in FIG. 1.
  • Figure 5 shows a cross section of the connector equipped with a contact part according to line B-B in Figure 1 in the assembly position during insertion of the contact part.
  • Figure 6 shows a cross section of the connector of Figure 5 in the locked position.
  • Figure 7 shows a cross section of the connector of Figure 6 with a mating connector shown schematically.
  • the figures show an electrical connector 1 and a contact part 2 which can be used therein, on an enlarged scale of approximately 5: 1.
  • the features and functional principles of the contact parts 2 are identical, so that a contact part 2 is explained in more detail by way of example.
  • a schematically illustrated mating connector 30 can be assembled with this connector 1 to form a complete connector.
  • the connector 1 consists of an elongated Isolierstoff ⁇ housing 3, which is traversed from a front side 4 to a rear side 5 by double row arranged in the longitudinal direction contact part chambers 6.
  • a finger 7 is formed in each contact part chamber 6 for fastening a contact part 2 inserted from the rear side 5.
  • the row-shaped arrangement of the contact part chambers 6 requires that opposite contact part chambers 6 share an inner wall 8.
  • a resilient finger 7 projects into the respective contact part chamber 6 on both sides of this inner wall 8.
  • the insulating material housing 3 passes through a stem-shaped profile opening 9, which serves to receive a push element 10.
  • the profile opening 9 'cuts all the contact part chambers 6 and creates the space for the deflection of the fingers 7.
  • the push element 10 can be shifted in the profile opening 9 between an assembly position and a locking position. ben and consists of a locking comb 11 and a cover plate 12 which are integrally connected to one another by transverse webs 13.
  • the thrust element 10 is double-T-shaped, the locking comb 11 and the transverse webs 13 corresponding in cross section to the profile opening 9.
  • the locking comb 11 is equipped with teeth 14 which lock the contact part 2 in the locking position in the contact part chamber 6.
  • the cover plate 12 is arranged outside the insulating material housing 3 on the front side 4 thereof. In the longitudinal direction L, the cover plate 12 surrounds the front side 4 with edges 15 on which grooves 16 are embedded on the inside. The grooves 16 interact with corresponding rails 17 of the insulating material housing 3 and guide the cover plate 12 along the insulating material housing 3.
  • the covering plate 12 there are plug-in openings 18 arranged in two rows, each of which is assigned to a contact part chamber 6 with its contact part 2. In order to facilitate the insertion of counter-contact parts 31, the plug-in openings 18 are expanded with finding funnels 19. Between the rows of the plug openings 18, a longitudinal slot 20 is made in the cover plate 12, which is aligned with the profile opening 9 and has an inwardly directed edge 21.
  • the mounting position and the locking position of the pushing element 10 are ensured by means of locking lugs 22, 22 ', 22' 'and locking openings 23, 23', 23 '' which are molded onto the insulating material housing 3 or onto the cover plate 12.
  • locking lugs 22, 22 ', 22' 'and locking openings 23, 23', 23 '' which are molded onto the insulating material housing 3 or onto the cover plate 12.
  • the shapes and arrangements of guide means 16, 17 and latching means 22, 23 on the insulating material housing 3 or on the thrust element 10 shown in the figures are an example, since diverse further embodiments are possible.
  • the following description represents the mode of operation of the connector 1.
  • the push element 10 is inserted into the profile opening 9 of the insulating material housing 3 and latching the previous animals.
  • the assembly position the contact partial chambers 6 on the front side 4 of webs 24 between the plug-in openings 18 are closed, so that no foreign bodies can penetrate here.
  • the contact part 2 is inserted into the contact part chamber 6 from the rear side 5 of the insulating material housing 3. This is only possible in the assembly position, since the teeth 14 of the locking comb 11 are displaced too far
  • Thrust element 10 would block insertion of the contact element 2.
  • the fully inserted contact element 2 abuts with its contact part box 25 at the front on a web 24 of the cover plate 12 and with a flag 26 against a projection 27 in the contact part chamber 6.
  • the finger 7 deflected during insertion engages in a recess 28 in the contact part 2 and resiliently is the first locking.
  • the thrust element 10 is pushed further in the longitudinal direction L and locked in the locking position.
  • the thrust element 10 can only be advanced if the contact part 2 has been completely inserted into the contact part chamber 6, since otherwise the teeth 14 of the locking comb 11 would be blocked by a part of the contact part box 25.
  • the teeth 14 of the locking comb 11 engage behind the contact part box 25 and thus create a second locking of the contact part 2.
  • the cover plate 12 also moves.
  • the plug openings 18 are arranged above the contact part chambers 6, so that the mating contact parts of the mating connector can be inserted and brought into engagement with the contact parts 2.
  • the mating connector 30 has at least one pin 32 which engages in the longitudinal slot 20 and in the profile opening 9 and additionally secures the first locking, ie the fingers 7.
