Detachable end piece for an electrical end connector

The innovation "relates to a detachable end piece for an electrical one End connector, having a base for attachment to a support and having a substantially self-aligning base perpendicular -from the base extending arm-

The end connection element here has an elongated Body made of insulating material, and has a central longitudinal slot for receiving a plate with printed Circuit and a number of recessed openings in the longitudinal slot for receiving contacts which engage in parts of the printed circuit on the board can.

The end connection element can have a certain length and according to the number of for the respective purpose

/ 2

be formed certain contacts. In order to be able to fasten the end connection element cut to length to a carrier, end pieces are provided which are detachably arranged at the opposite ends of the end connection element. It is common practice to sell end connection elements which are cut to a specific length according to requirements. The end pieces are supplied together with this end connection element. The end pieces can also be stored or shipped separately from the end connection elements, or they can be attached to them via clips. The final connection to the end connector occurs when it is attached to a beam or other part. This practice has the disadvantage that the end pieces can fall off their temporary attachment. They must also be released from their preliminary attachment for final attachment to the end connector. This results in considerable costs, which arise in addition to the costs of the preliminary connection. Furthermore, there is the risk that an end piece can be damaged or lost before it is finally attached.

The present innovation now sees a detachable end piece for an electrical end connection element, which is a base part for attachment to a carrier, a arm extending substantially normal to the base ■ and comprises a flexible plate-like element which is arranged on one side of the arm and at a distance lies parallel to this. This element can slide into a seam, which is formed by a pair of recesses in the Body of the end connector is defined and thus secure the end piece releasably on this connection element. The arm has a flexible lip on the same surface as the plate-like element, which is under the End connector plane can snap when the plate-like element is slidably inserted into the recess.

The end piece can be a single synthetic plastic be part, which is sufficiently elastic to "bend" with the plate-like element of the arm at the end connection el again ■ to be attached-

According to the innovation, the end piece can also be "both ends" of the connector element.

The! Firing is shown below using one in the drawing Described in more detail illustrated embodiment.

slot 2 are recesses 3 for receiving contacts 4-provided, which end parts 5 have. These contacts lie opposite each other in each recess, so that parts of the contact protrude into the central longitudinal slots 2.

The end piece described in the present innovation is integral and made of a plastic material such as nylon and is usually of an L-shape.

An arm 6 of this L is designed to be essentially rigid and thus forms the basic part. The other arm 7 has a flat surface 8, which is integral with a plate-like Element 9 is provided. The plate-like element is connected to the arm 6 and the surface 8 via a neck 10. As shown particularly in Fig. 5, the plate eaähnli before element is at a distance from the surface 8 of the Arm 7 below the T7erbindungshalses 10 and is sufficient flexible, including a certain amount of movement towards this arm !allow.

The end piece is now fastened in such a way that the underneath free end of the plate-like element engages in a clamping area 3 and is slid downward under pressure. During this gate gear presses the lip 11 against the end face of the end connector, 5 ^e! ^ - ^oc -k- the flexibility of the plate-like element 9 compensates for this pressure. As shown particularly in Fig. 3, the lower part of the plate-like element bends away from the surface 8,

so that proper sliding within the recess 3 is guaranteed. Is the plate-like element fully inserted, "see the tower below of the lower end of the connector element and snaps it into place.

After attachment, the plate-like element lies completely securely in the recesses and the neck part 10 is located within the central longitudinal slot 2. The lower free end of the plate-like element hits the bottom of the recess 3 and thus limits the downward movement of the end piece. By engaging the lip 11 with the lower surface of the end connecting element, an undesired upward movement of the end piece is also avoided. In this way, the new end piece is completely securely attached to the end connection element. If necessary, however, it can be dismantled from this again.

The innovation according to the end piece can spring on the end of the Length of cut end connector attached v / ground, after which the end connector with the attached End pieces can be relocated, transported and sold as a unit for immediate use.

The body of the end connector may be reinforced with fiberglass Diallyl phthalate or another synthetic plastic material.
