Definitions

  • the present invention generally relates to the field of electrical connectors, and particularly to an electrical connector for vehicle airbag triggering systems.
  • electrical connectors are locked in place by means of two locking systems to ensure and to maintain the position in the counter-part connector.
  • Such a known electrical connector has primary locking tabs with latches that engage in corresponding slots in the counter-part connector.
  • the latches generally have sloping flanks in the plugging direction as well as in the opposite direction to enable an unplugging of the electrical connector.
  • the principle of the secondary locking system consists in blocking the latches of the primary locking tabs into the slots via an additional member, mostly called connector position assurance (CPA) member.
  • CPA connector position assurance
  • the CPA member is usually inserted into the housing of the electrical connector once the latter is plugged in the counter-part connector, such that secondary locking tabs of the CPA member in form of rigid longitudinal rails enter free slots behind the primary locking tabs.
  • the rails prevent the latches from swinging back radially inwards, thus ensuring that the connector has actually been latched. For deplugging first the CPA member needs be deplugged and only then the primary locking tabs may be disengaged.
  • US-A-5947763 discloses an electrical connector according to the preamble of claim 1.
  • WO 03/103102 A1 there is known an electrical connector, called closed CPA matting, with an alternate CPA member that can be entirely premounted to the housing of the electrical connector before the plug-in process is started.
  • the CPA member has secondary locking tabs, wherein wedge-shaped projections are formed on the sides of a pair of secondary locking tabs, turned away from one another, said wedge-shaped projections causing the secondary locking tabs to bend behind the primary locking tab that is then locked in place.
  • the primary locking tabs can, in the plugged state, no longer deflect in the direction of the plug-in axis as they are blocked by secondary locking tabs in form of rigid longitudinal rails on the one hand or bent secondary locking tabs on the other hand.
  • the electrical connector cannot be removed from the counter-part connector, unless the CPA member is deplugged as above mentioned.
  • an electrical connector comprising a housing having at least one primary locking means for locking the electrical connector with an electrical counter-part connector, and a connector position assurance CPA member, which is engageable with the housing and comprises at least one secondary locking means blocking the primary locking means.
  • At least one security locking tab is thereby formed on the CPA member or the housing and adapted to latch behind a security shoulder provided on the other of the CPA member and the housing in order to prevent an accidental disengagement of the CPA member.
  • the electrical connector further comprises a releasing tab adapted to radially deflect the security locking tab in order to actively disengage the engaged CPA member.
  • the housing can comprise at least one primary locking tab for latching into a recess of an electrical counter-part connector
  • the CPA member can comprise at least one secondary locking tab blocking the primary locking tab in the recess of the electrical counter-part connector when the electrical connector is plugged into the electrical counter-part connector in a plug-in direction.
  • the security locking tab is radially deflectable to actively disengage the engaged CPA member.
  • An operator aiming to dismount the CPA member from the housing has first to press, respectively lift, the security locking tab inwards, respectively outwards, and then to pull the CPA member out of the housing. This two-step process prevents an operator to mistakenly disengage the security locking tab. Further, the disengagement according to the invention can be carried out by the operator without extra tool while prior art connectors usually requires the use of such a tool to disengage the CPA member.
  • the security locking tab can have a sloping surface for sliding along a sloping surface of the security shoulder during the engagement of the CPA member with the housing.
  • the orientation of the sloping surface of the security locking tab and of the sloping surface of the security shoulder can cause a radially deflection of the security locking tab during the engagement of the CPA member.
  • the security locking tab and the security shoulder are adapted such that the first contact between them during the engagement of the CPA member occurs between their sloping surfaces. The operator engaging the CPA member with the housing thus only has to push the CPA member into the housing for the security locking tab to lock in place. He needs not e.g. pull the security locking tab during the engagement procedure to pass the security shoulder of the housing, neither needs he press or fit the security locking tab behind the security shoulder.
  • the CPA member can be a molded plastics part.
  • the CPA member is engageable with the housing before plugging the electrical connector into the electrical counter-part connector.
  • Two secondary latching tabs can be adapted to spring radially behind one primary locking tab.
  • the housing 2 is composed of a connector body 7, on which primary locking tabs 5a, 5b as a primary locking system are formed, and a cover 8.
  • the cover 8 is preferably fastenable onto the connector body 7 by means of cover tabs 9a, 9b that lock in corresponding grooves 10a, 10b of the connector body 7.
  • the housing 2 comprises a front part 14 to be plugged in a corresponding counter-part according to a plug-in direction along an axis 20, and a back part 15 adapted to receive the CPA member 3 as a secondary locking system.
  • the primary locking tabs 5a, 5b are formed on the front part 14 of the housing 2 of the electrical connector 1 on each side of the plug-in axis 20.
  • the primary locking tabs 5a, 5b extend longitudinally and are radially bendable. They furthermore comprise latches 22a, 22b with back 24a, 24b and front sloping flanks 25a, 25b or taperings on their external surface.
  • the front sloping flank 25a, 25b of the latch 22a, 22b of each primary locking tab 5a, 5b slides on a corresponding shoulder of the counter-part connector 54 thus each latch 22a, 22b elastically deflects radially inwards.
  • the latch 22a of the primary locking tab 5a latchs behind the shoulder into a slot or groove.
  • the electrical elements of the electrical connector 1 consist in conducting wires 13a, 13b connected to sleeves 11a, 11b that are fixedly inserted inside the housing 2.
  • the wires 13a, 13b are for example and as shown crimped to the sleeves 11a, 11b, this particular embodiment making use of two wires 13a, 13b and two sleeves 11a, 11b.
  • the sleeves 11a, 11b are located in the front part 14 of the electrical connector 1, such that when the electrical connector 1 is plugged onto the corresponding electrical connector counter-part 54, electrical pin type contacts at the connector counter-part 54 penetrate into the sleeves 11a, 11b.
  • Ferrite elements 12a, 12b may surround the sleeves 11a, 11b and serve for filtering possible electrical disturbances.
  • the electrical connector 1 of the present embodiment is particularly adapted to be used as a gas generator electrical connector in a vehicle air bag system, which can be plugged in a mating electrical connector of a gas generator.
  • the electrical connection of the gas generator electrical connector to the mating electrical connector is then provided by the sleeves 11a, 11b, and the electrical connection to an air bag controlling unit is provided via wires 13a, 13b.
  • Fig. 2 shows a perspective view of the CPA member 3 as a secondary locking system, being preferably a one-piece member consisting of a molded polymer material.
  • the CPA member 3 can be shifted according to the plug-in direction into the back part 15 of the beforehand assembled housing 2 containing the electrical elements.
  • the CPA member 3 generally comprises an outer part in form of a casing 16 matching in its outer form with the housing 2 and inner elements in an inner part 17.
  • the casing 16 When the CPA member 3 is mounted to the housing 2, i.e. in a mounted state of the electrical connector 1, the casing 16 surrounds the back part 15 of the housing 2 at least partially or completely.
  • the casing 16 comprises a back section 18, through which the wires 13a, 13b of the electrical connector 1 are led to e.g. a controlling unit of an air bag system, and a lateral section 19 such that the CPA member 3 can be handled by an installer on the assembly line to properly insert and mount the CPA member 3 to the housing 2 in the plug-in direction.
  • the inner part 17 of the CPA member 3 comprises, among others, rails 21a, 21b and secondary locking tabs 4a to 4d, which extend in the plug-in direction and are slidable in corresponding grooves in the housing 2. In case the electrical connector 1 is in a mounted state, said inner part 17 of the CPA member 3 is located inside of the housing 2.
  • the rails 21a, 21b are adapted to move a short circuit clip of the electrical counter-part connector 54.
  • the counter-part connector 54 of the electrical connector 1 of the enbodiment has generally pin contacts and a short circuit clip for electrically shortening said pin contacts.
  • the secondary locking tabs 4a to 4d are fastened to the casing 16, typically are integrally formed therewith, and extend in pairs along the plug-in direction. They are elastically bendable, and a wedge-shaped projection 23a to 23d is formed on each secondary locking tab 4a to 4d such that two facing secondary locking tabs 4a, 4d bend towards one another when the wedge-shaped projections 23a, 23b strike the counter-part connector 54.
  • the latch 22a of the primary locking tab 5a strikes at first against a shoulder of the counter-part connector 54. If the electrical connector 1 is pushed further into the counter-part connector 54, the latch 22a slides along the shoulder, such that the locking tab 5a bends radially in the direction of the plug-in axis 20, while the secondary locking tabs 4a, 4b are prevented from deflecting in the transversal direction by the bent primary locking tab 5a.
  • the lateral section 19 extends from the back section 18 in the plug-in direction up to a front end 30, where longitudinal security locking tabs 6a, 6b are formed.

  • an electrical connector 1 according to the embodiment can include several, preferably two, security locking tabs 6a, 6b.
  • each security locking tab 6a, 6b is integrally formed on the lateral section 19 of the casing 16 of the CPA member 3. It extends longitudinally into the plug-in direction and is composed of three successive sections, namely a back section 31, a middle section 32, and a front section 33.
  • the security locking tab 6b is fastened to the front end 30 of the casing 16 through the back section 31 in form of a rail. From the front end 30 of the CPA member 3 and in the plug-in direction, the back section 31 departs progressively from the plug-in axis 20 radially outwards up to the middle section 32, which is preferably parallel to the plug-in axis 20.
  • the back 31 and the middle 32 sections are so dimensioned that it is possible for a user to press them in order to bend the security locking tab 6a towards the plug-in axis 20.
  • the security locking tab 6a ends with the front section 33.
  • the front section 33 follows the middle section 32 and is closer to the plug-in axis 20 than the latter.
  • the front section 33 includes two opposing lateral security projections 37a, 37b, a front surface 34, an intermediate surface 35, and a lower surface 36 (see Fig. 2 ).
  • Each security projection 37a, 37b comprises a sloping surface 38, an middle surface 39, a retention surface 40, and a lateral surface 41.
  • the other elements of the security locking mechanism of the embodiment are part of the housing 2 of the electrical connector 1.
  • two parallel supporting surfaces 43a, 43b are formed, which are perpendicular to the lateral surface 42 and parallel to the plug-in axis 20.
  • An abutment surface 44 which is also formed on the lateral surface 42, connects the two supporting surfaces 43a, 43b and is perpendicular to the lateral surface 42 of the housing 2, to the supporting surfaces 43a, 43b, and to the plug-in axis 20. From the lateral surface 42, the supporting surfaces 43a, 43b and the abutment surface 44 lead outwards of the housing 2.
  • Each security shoulder 45a, 45b is formed in the direction of the other supporting surface 43a, 43b.
  • Each security shoulder 45a, 45b comprises a lateral surface 49, which faces the lateral surface 49 of the other security shoulder 45a, 45b, a retention surface 48, a middle surface 47, and a sloping surface 46.
