Definitions

  • the invention relates to an electrical connector, especially for use between a can (squib) and an electrical control unit for one Restraint system in motor vehicles, for example a Airbag.
  • Such a connector has a very limited size (for example length: 2 to 3 cm, width: approx. 1 cm, Height: 0.1 to 1.0 cm). It follows that individual components of the connector or the associated Can only have an extremely small size, nevertheless but in terms of safety application (for example belt tensioner, airbag) a light Assembly on the one hand and high functional reliability on the other hand is required.
  • safety application for example belt tensioner, airbag
  • the locking member be pre-assembled and lies in the pre-assembled Starting position against the action of a spring in a raised position. Connector and socket can be locked against the action of the spring.
  • the present invention seeks to provide an alternative Be offered for a connector that meets the following requirements: A locking element for secondary locking of housing and box be pre-assembled.
  • the locking member should be in the pre-assembled position the insertion of the connector (or its corresponding housing section) at least lighten in the can.
  • the locking member should then be in its final position opposite the Housing of the connector to be brought in it the desired function of a secondary lock against resilient locking arms on the housing.
  • the spring arms have a certain elasticity, that means they can be in different positions appropriate preload or release of the preload to be brought.
  • One position (before assembly) fix the locking member in relation to the housing. By pressing the locking member, the corresponding one Carried part of the housing and can in the box be used.
  • the spring arms should however, from the locked position relative to the Loosen the housing again.
  • the Locking arms behind the locking arms of the housing In a locking arm can also be used in this position to break a short circuit bridge, like still is explained.
  • the movement sequence is therefore two-stage:
  • the locking member and housing in the pre-assembled position performed together, then the locking member is removed from the anchoring position solved with respect to the housing and moved relative to this.
  • the inner surface formed, for example, as an inclined surface in the area of the box (the inclined surface can also be on Spring arm are formed) is preferably in the area of a separate insulating body, which in the mostly metallic, can body is used. This creates the ability to insulate with high Fit dimensional accuracy and thus exact positioning of the connector housing in the area to ensure the can.
  • the arms mentioned stand from a common base part.
  • the spring arms at a distance from the locking arms arranged.
  • the spring arms can be unloaded run at an angle not equal to 90 degrees to the base part.
  • the angle between the outer surface of the Spring arm and the underside of the base part ⁇ 90 °. In other words: run in a side view the spring arms, starting from the base part, each after Outside.
  • the spring arms can on their, facing the can Outside surface with an undercut (a bead-like Depression).
  • This undercut serves as a support surface on a corresponding level in Area of the inner wall of the housing to the said Set pre-assembly position. In this position the locking member is on the housing level on. If the user presses the base part, he leads the connector housing is automatically included.
  • the recess can have a base area that is perpendicular to the direction of movement of the locking arms.
  • the spring arms can be used on the outside be formed an inclined surface.
  • This sloping surface serves as a ramp surface on a corresponding Ramp arranged in the area of the box.
  • this inclined surfaces / ramp can be the locking member when plugging further onto the box from the pre-assembly position be solved again.
  • the spring arms run into the area of the can or one Can insert the spring arms under tension "pressed in” and at the same time the Undercut from its rest position opposite the solved on the housing side, so that then a Relative displacement of the locking member and housing can be done.
  • the spring arms of opposite sections of the base part For example in the case of a rectangular base part, the Spring arms in the area of two parallel sides.
  • the Distance between opposing spring arms in the unloaded Condition can be larger at its free ends than in Area of the base part, being in the side view a geometry that widens conically downwards results.
  • the spring arms are arranged, for example, in such a way that their direction of movement when detaching from the pre-assembled Starting position towards the locking arms runs.
  • locking arms There can be one or more locking arms as well as one or more spring elements on each side of the base part to be ordered.
  • the arrangement of the spring arms outside Every connection to the locking arms increases safety the establishment.
  • the locking member has a rectangular base part, of which on two opposite sections each a locking arm protrudes vertically and from which to the two remaining opposite side sections one or two spring arms each in the same direction protrude, preferably inclined so that opposite Have a greater distance between spring elements at the free end than in the area of the base part.
  • the pre-latching can be tilted compared to the Carry out the connector housing more easily, if necessary even under tension.
  • the connector shown in Figure 1 corresponds with regard to its basic structure that according to DE 198 40 726 C2. To this extent, reference is made to this taken.
  • the connector therefore has a side view an L-shape, essentially in Figure 1 only a plug part of the housing 10 is shown (which forms the shorter L-leg). This part of the case essentially has a rectangular basic shape on. Openings 12 run in plug-in direction S in which Contact springs (not shown) are arranged, the with corresponding contact pins 52 of a corresponding one Box 50 ( Figure 3) in the locked state of Contact connector and socket 50.
  • Resilient locking arms also extend in the plug-in direction S. 14, 16 of opposite sections of the housing 10. All these features are of that in DE 198 40 726 C2 described connector known.
  • the locking member 20 has a rectangular Base part 22 two locking arms 24, 26, the from opposite side portions 22a, 22b of the Stand base part 22 vertically.
  • the locking arms 24, 26 in the upper part (adjacent to the base part 22) protruding profile strips 24p, 26p, while the lower section 24u, 26u is plate-like is designed, parallel to the outer edges of the sections 22a, 22b of the base part 22.
  • the locking member 20 is partially See engagement with the housing 10. It can also be seen the lower portion 24u of the locking member 24 which the corresponding locking arm 14 in this plug-in position towering downwards.
  • the spring arm 28 is from Base part 22 in the same direction as the locking arms 24, 26 from, but not vertically, but inclined, the angle between the lower face of the Base part 22 and the central longitudinal axis M - M of the spring arm 28 is approximately 80 °.
  • a bead-like depression 28h trained, creating a kind of undercut is formed.
  • At the free end of the spring arm 28 is one Inclined surface 28s formed so that the end region of the Spring arm 28 is narrower than that articulated on the base part 22 Section.
  • Figure 3 shows a first assembly stage: the locking member 20 is in a corresponding opening 40 of the Housing part 10 used, this housing part on the inside at opposite sections has a step-like thickening 42.
  • this initially runs with the Inclined surfaces (such as 28s) on this level 42 swung inward and then springs in the provisional locking position shown in Figure 3.
  • This position is a kind of pre-assembly, which can be done at the manufacturer of the connector, so that connector and locking member together and can be delivered captively to the customer.
  • the plug connector is shown in FIG. 3 arrangement shown further on an associated can with an insert 54 (insulating body) and through Pressure on the locking member 20 in the insertion direction S. pressed.
  • the sloping surfaces (like 28s) run Spring arms 28, 30, 32, 34 on corresponding inclined surfaces of the insulating body 54 and in turn pressed inward (direction of arrow I) so that it over 4 into the position shown in FIG. 5 shown end position where the connector is completely locked with the can.
  • the Lock position is on the one hand Contacting the contact pins 52 with the corresponding Springs of the connector reached, further through the Deflection of the locking arms 14, 16 in a corresponding, circumferential groove 56 of the can 50 (in FIGS. 3 to 5 this groove section 56 runs parallel to the plane of the drawing) and this position is finally secured through the locking members 24, 26, which are now are located behind the locking arms 14, 16.
