The present invention is directed to an electrical connector strip having opposite end faces and each comprising an insulating housing detachably joined together by interengaging means on said end faces to form a strip.

The connector may comprise an electrical terminal suitable for being connected to the electrical conductor by a conductor terminal machine, for example, a machine that inserts the conductor into the conductor receiving slot of the terminal for electrically connecting the conductor to the terminal.

Especially in mass production operations for the provision of electrical devices comprising conductors and connectors, the strips of the connectors are wound around a storage reel, which can be unwound by the machine in order to avoid disturbing the conductor manufacturing operations and in terms of space utilization. You must be able to lose. It is an object of the present invention to provide this function.

Therefore, according to the present invention, the engagement means comprises a pair of hook members provided on each end face of each housing, and each hook member of each pair of hook members has a hook portion of the hook member on an adjacent end face of the next adjacent housing. A hook portion that is loosely engaged with each other and extends across the end surface and protrudes from the post and a support standing up from the end surface. The support should be freely sized for the activity between the interlocking hook portions to allow bending of the connector strip between the straight structure and the arch structure so that the strip can be wound around the storage reel.

The hook portion of each hook member preferably extends at right angles to the strut portion of the hook portion and these portions are planar.

The struts of each connector and the hook member on one end are provided with different cross sections whose hooks are spaced from the other end face such that the necessary space is provided between the end faces of the adjacent connectors so that the projections, for example the conductor guides, are received on the end faces. It should be sized to be spaced more widely from the end face than the hook portion above.

The protrusion may serve to limit the warpage of the strip in one or more directions.

One end face of each housing may be formed with a rib that guides the hook member on the adjacent end face of the next neighboring housing to engage with the hook member of the one neighboring surface.

According to an embodiment of the present invention each housing is rectangular and the hook portion extends from the strut in the longitudinal direction of the housing.

The invention will now be described by way of example with reference to the drawings in order to show a better understanding of the invention and how it is implemented and effected.

As shown in FIG. 1, in the strips of the same electrical connector 2 (only a short length portion is shown), each electrical connector comprises an insulating housing 4 with opposite end faces 6, 8, respectively. . The housings 4 are detachably joined together by means of interengaging means 10 on the end faces 6, 8 to form the strip.

As best shown in FIGS. 3 and 4, the interlocking means 10 comprises two pairs of spaced hook members 12 on the end face 6 of each housing 4 and two pairs on the end face 8. Each of the spaced hook members 14. The pair of hook members on each end face 6, 8 are spaced from each other in the longitudinal direction of the housing 4.

Each hook member 12 comprises a support 16 upright from the end face 6 and a hook 18 directed to the other hook member 12 forming a pair. Each hook member 14 of each pair includes a strut portion 20 standing up from the end face 8 and a hook portion 22 in a direction away from the pair of other hook members 14.

As best shown in FIG. 3, the hook portions 18, 22 extend across the end faces 6, 8 substantially parallel to their end faces, with each hook portion 18 being the closest hook portion. It is engaged between the 22 and the end surface 8. As can be seen in FIG. 3, the strut portions 16 and 20 allow relative angular movement between the hook portions 18 and 22 so that the strip of the connector bends into an arch structure as shown in FIG. The activity should be sized freely. In practice, the strip will usually contain hundreds of connectors. Because of its flexibility, the strip can be wound around a storage reel for feeding the connector to a machine (not shown) that terminates the conductors in the connector.

As shown in FIG. 3, the hook members 12, 14 are formed such that their hook portions extend at right angles to the posts.

The strut 16 of the hook member 12 is substantially longer than the strut 20 of the hook member 14 as shown in plan view in FIG. Each pair of hook members 14 is provided with guide ribs 26, the hook portions 22 of the hook members guiding the corresponding hook portions 18 to engage under the hook portions 22. For chamfer 28 (shown in FIG. 5). Together with the lower end (shown in FIG. 4) of each rib 26 of one housing to engage the hook member 14 of one housing 4 with the corresponding hook member 12 of the immediately adjacent housing 4. It is fitted between the pair of hook members 12 of the immediately adjacent housing. The housing is moved towards each other until the respective hook members 12, 14 are completely engaged with each other.

As shown in FIG. 4, each housing 4 has only one electrical terminal 32 having a conductor receiving slot 34 into which the conductor is fitted so as to be electrically connected to the terminal 32 by the aforementioned mechanical means. Each of which has a row of cavities 30. Protruding from the end face 16 of each housing 4 on the hook member 12 is a lead guide protrusion 36 and the lead stop bar 38 is spaced from the end face 8 of the housing 4. Is located. In the straight position of the strip of the connector as shown in FIG. 1, the engagement of the protrusions 36 and the stop bar 38 to each other limits the bending of the strip in the opposite direction to that shown for reference in FIG. Conversely, the bending of the strips of the connector in the direction shown in FIG. 2 is limited by the opposing engagement of the lower parts of the housing 4 with each other as shown in FIG.

Each connector 2 has a cover 40 (shown in FIGS. 1, 2 and 4) which is detachably connected to it and extends to the right over the next adjacent reducer 2 (shown in FIGS. 1, 2 and 4). On the lower side of 40 a wire is provided which supports the nipple 42 corresponding to each pupil 30 of the connector, which is clearly shown in FIG. When the lead is connected to all the terminals of the pupil 30 of the connector 2, the cover 40 of the connector drops away from it and the nipple 42 is turned towards the pupil 30 and then the cover is 42 is assembled to the connector 2 to support the conductor down into the slot 34 of the terminal 32.
