Definitions
- the invention relates to a device for coding connectors with pin contacts, wherein a mating connector is provided with closable openings for coding pins and the connector at the unlocked locations of the mating connector has coding pins which protrude into the openings of the mating connector in the assembled state.
- Such a device is e.g. made known by EP 0179999 A2.
- a multi-pole connector for a plug-in module is provided along the side of the field provided for the pin contacts with molded pin-like tongues which can be inserted into corresponding openings in the mating connector.
- the openings are partially closed by locking pins.
- No coding tabs are provided at these points.
- This type of coding has the disadvantage that, in addition to the pin field for the plug connections, additional space is required which cannot be used for connection purposes.
- the invention has for its object to provide an inexpensive and space-saving coding device.
- the pin contacts are very slim and can be easily bent. In the event of incorrect plugging, there is therefore the risk that a pin contact, which strikes a closed chamber, is slightly shifted and bent, without this being noticeable in the high overall plugging force.
- the support sleeve sits on the bottom of the connector housing. It is considerably more resistant to kinks than the pin contact. Attempting to plug in an assembly in the wrong slot means that the assembly can no longer be inserted even with increased effort without damaging the pin contact or the support sleeve.
- the support sleeve can e.g. be hollow cylindrical, the inner diameter being slightly less than the diagonal thickness of the pin contact. As a result, the support sleeve is held clamped on the pin contact.
- the development according to claim 4 can be realized in a simple manner by squeezing the support sleeve between two crimping jaws.
- the pin contact is clamped in two different places, which improves the clamping effect.
- the support sleeve is pushed smoothly over the pin contact until the outer notches hit. Due to the angular offset between the two notches, a point-like contact is achieved on the longitudinal edges of the pin contacts.
- the pin contact between the two clamping points is twisted elastically, which results in a particularly permanent clamping effect.
- An additional holding effect results from the fact that the longitudinal edges of the pin contact can be slightly deformed at the clamping points, which is associated with a corresponding latching effect.
- the two notches can be created in the same tool and with the same setting.
- a connector 1 is equipped with pin contacts 2.
- the pin contacts 2 are designed so that contact can be made with a mating connector, not shown, with socket contacts. In places where for structural reasons no socket contacts can be arranged within the field provided, pin contacts 2 can be used in the connector 1 for coding purposes. In this case, the receiving chambers for the socket contacts of the mating connector assigned to the unoccupied plug points are closed with locking pins.
- the pin contacts 2 serving as coding pins are provided with support sleeves 3 amplified, which are axially attachable to the pin contacts 2 according to the arrow shown. They are provided with two pairs of diametrically opposite notches 4, 5, which oval deform the cross section of the cylindrical support sleeves 3 at these points.
- the outer notches 5 are adjacent to the free pin end, the inner notches 4 are arranged at the other end of the support sleeve 3. These are supported on the base of a housing 6 of the connector 1 and enclose the pin contacts 2 over their entire length. From the figure it can be seen that the two pairs of notches 4 and 5 are angularly offset from one another.
- FIG. 2 shows that the inside diameter of the support sleeve 3 is larger than the diagonal thickness of the pin contact 2, which is square in cross section.
- FIG. 3 shows the cross section of the support sleeve 3 in the area of the inner notches 4.
- the support sleeve 3 is thereby deformed into an approximately oval cross section, the small semiaxis of the inner ellipse being larger than the thickness of the pin contact 2.
- the support sleeve 3 is rotated relative to the pin contact 2 so far that two opposite longitudinal edges of the pin contact 2 touch the inner wall of the notches 4.
- FIG. 5 shows the cross sections of the two notches 4 and 5. They result in two elliptical oval zones, the large semiaxes of which are offset in their angular position by approximately 35 degrees from one another about the central axis of the pin contact 2. The points of contact with the longitudinal edges of the pin contact 2 are thus clockwise or counterclockwise to the side of the small semi-axes, so that the pin contact 2 between the two notches 4 and 5 is twisted accordingly. There is a permanent elastic clamping effect between the pin contact 2 and the support sleeve 3, whereby a secure mutual liability is guaranteed.
