Definitions
- the invention relates to a knife contact for electrical connectors with a strip-shaped contact part, a support body which can be fixed to the connector housing and with crimp attachments for fixing an electrical conductor and its insulating jacket on the knife contact.
- a known knife contact has a contact part with a fastening recess with transversely projecting gates which are folded back over part lengths. Due to the fastening recess, this knife contact is mechanically unstable and weakened in cross section next to the recesses, as a result of which the current flow is adversely affected. In addition, the knife contact is not capable of miniaturization.
- Another known contact is to create a supporting body over a partial length by means of an attachable box-shaped sheet metal part which can be fixed to the contact part by means of tongue-shaped gates which can be bent into recesses in the contact part. Apart from the fact that the shaped sheet metal part acting as a support body can only be produced in a complex manner, the shaped sheet metal part does not act securely for fixing the knife contact.
- this object is achieved by a sheet metal blank with a substantially rectangular section extending over part of the length thereof to form the contact part and a tab projecting beyond the section on both sides to form the support body, and tabs lying in series with the section and projecting laterally therefrom for the formation of
- the knife contact can be formed by simple bending operations from a single sheet metal blank, which results in a simple design and advantageous implementability of the knife contact in terms of tool technology and also ensures exact positional security of the same in the plug housing.
- the knife contact is characterized by a mechanical robustness, which allows the use of materials of lower strength, but higher electrical conductivity. Finally, the flow of current in the knife contact is unimpeded by dispensing with fastening cutouts.
- the flaps preferably have partial sections on the arc sections adjoining the section forming the contact part and flat sections adjoining them, the arc sections and the flat sections of the tabs forming the section of the sheet metal blank forming the contact part parallel to the fold line plane tower over.
- the arc sections are designed in such a way that the section forming the contact part in the region of the tabs and the tabs forming the support body have a substantially meandering cross section transverse to the plugging direction. There is the possibility here of leading the support body to the contact part with any width by means of corresponding radii on the arc sections.
- the flat portions of the tabs either extend parallel to one another or are designed to extend obliquely towards the free end.
- the tabs can be completely or sectionally rigid or resilient, so that the knife contact with the tabs can be inserted and held in the connector housing under prestress, if necessary.
- the free ends of the two sections can preferably have bends facing each other over approximately half their axial length.
- the arch sections have at least one indentation or indentation serving as stiffening, for example a bead. This prevents unintentional bending of the tabs, for example when inserting the knife contact in the connector housing.
- the tabs can have recesses in the area of the arch sections and / or over part-width sections of the flat sections.
- FIG. 1 shows a connector housing with a knife contact in section
- FIG. 2 shows a knife contact in perspective
- FIG. 3 shows a knife contact in side view
- FIG. 4 a top view of a knife contact.
- FIG. 5 a partial section of a knife contact in FIG.
- FIG. 8 a sheet metal blank for a knife contact in plan view
- FIG. 9 a section of a knife contact in the area of the plug end in side view, enlarged.
- 1 denotes a connector housing for receiving knife contacts 2.
- the individual knife contact 2 has a contact part 3, a support body 4 for the purpose of axially fixing the knife contact 2 in the plug housing 1 and crimp attachments 5 and 6.
- the knife contact 2 is formed by a single sheet metal blank 7 (FIG. 8), which over partial lengths has a substantially rectangular section 8 for forming the contact part 3 and section 8 laterally projecting tabs 9, 10 and 11 for forming support bodies 4 and
- the sheet metal blank 7 is folded with the section 8 along a fold line 12 over the length of the knife contact 2 and the support body 4 with the flaps 9 extending to both sides of the fold line 12 by 180 * .
- the lobes 9 forming the support body 4 are, as illustrated in FIG. 2, bent back over curved sections 9 ', which results in an essentially meandering cross-section in the region of the support body 4 through the contact part 3 and the tab 9 (FIG. 5). .
- the curved sections 9 'and the flat sections 9''adjoining the curved sections 9' protrude beyond the contact part 3 parallel to the plane of the fold line, thereby forming support surfaces on the support body which, when the knife contact 2 is inserted into the plug housing 1 with plug housing surfaces at 13 ( Fig.l) come to the plant.
- the support body 4 can be gripped behind in the connector housing 1 by means of a bendable connector housing-fixed attachment 14 (FIG. 1) which can be fixed in the rear engagement position by means of a clamping body 16 which can be inserted into the connector housing 1.
- Arch sections 9 1 or the arch sections 9 'and parts of the planar sections 9 1 ' can be provided with beads 15 (FIG. 5) which serve to consolidate the arch sections 9 'and help to prevent the tabs 9 from being accidentally bent back.
- the curved sections 9 • and the flat sections 9 ′′ of the tabs 9 are provided with cutouts 18 (FIG. 6), which are preferably designed to be trapezoidal. There is the possibility of engaging or supporting an axial fixation of the sensor contact by engaging plug housings (not shown) in the recesses 18.
- the free ends of the flat sections 9 ′′ are bent over part of their length 9 ′′ ′′ in the direction of the fold line plane 12 and thus form a box-shaped support body 4.
- This support body 4 is drawn is characterized by great stability. While in the exemplary embodiments shown, the tabs 9 * 'extend essentially plane-parallel to one another, there is also the possibility of the sections 9 r ' of the tabs 9 being inclined outwardly towards the free end and the tabs 9 either being rigid or resilient. An oblique exposition of the sections 9 ′′ enables the compensation of tolerances between the knife contact 2 and the receptacle 19 for the latter in the plug housing 1.
- the tabs 10 and 11 of the sheet metal blank 7 are positioned at an angle to the fold line plane of the contact part 3 and serve to fix an electrical conductor (not shown) or its insulation.
- the contact part 3 is, as shown in FIGS. 8 and 9, at the free end of section 8 via a
