Description

DETAILED DESCRIPTION OF THE INVENTION The present invention combines the individual conductors of a first planar array of conductors into a second parallel array in which at least some of the individual conductors are laterally separated from the individual conductors of the first array. The present invention relates to a connector for connecting arbitrarily selected individual conductors of a planar array of conductors. %
In particular, the present invention relates to a kit for assembling and configuring such a connector.

With the increasing demand for complex electrical wiring, conductor plane arrays (where the conductors are on parallel planes and are laterally displaced from each other) are becoming more and more popular.
It is often necessary to interconnect the individual conductors of a plurality of flat cables, for example two flat cables. On the other hand, in order to minimize inventory and capital costs, it is desirable to eliminate the need for different connectors for different interconnect combinations. At the same time, the connector should be designed to be easy to manufacture using mass production techniques, to be relatively simple to assemble and use on site, and to minimize operating costs. In addition, the connector should be of a relatively small size to meet the requirements where compact and unobtrusive equipment is required, especially for under-carpet cabling where a low profile is essential. be.

According to the invention, the individual conductors of the first conductor planar array are
A connector assembly kit for connecting pre-selected individual conductors of a second parallel planar array of conductors, wherein at least some of the individual conductors are laterally spaced from the individual conductors of said first array. The kit includes a plate-shaped insulating body, and a plurality of i- and second solid contact portions are disposed on the first and second surfaces of the body, respectively. Contact locating means are formed for aligning with the respective conductors of both arrays, and certain of the contact locating means include through sockets communicating with both sides of the body, and child portions are disposed within respective locating means, and the first and second inner end contact portions disposed by the predetermined locating means are integrally coupled to each other via a main body portion inserted into the through socket; Grooves (plurality) extend between the second contact portion arranging means and the predetermined arranging means in the busbar holder by passing through the main body laterally, and the busbar portion is arranged in the preselected grooves (plurality). electrically connect a preselected second contact portion with a laterally spaced first contact portion associated with the feedthrough socket, and connect the assembled connector from the kit to both the conduit and the second conductor arrangement. The preselected individual conductors of the knee row can be connected to the laterally spaced conductors of the first array by interposing them between the conductors.

Thus, a single kit is suitable for configuring selectable interconnects.

This connector can be, for example, a connector for use in a connector of the type disclosed in European Patent Publication No. s 33009:34, No. 3, dated February 23, 1983.

In the connector of the same application, contact elements that engage the conductor are arranged on the cable engagement surface of the insulating housing body at the same pitch as the conductor of the flat cable, and the contact elements and the cable conductor are aligned by tightening the surface to the cable. is connected to. In use, the actuator is interposed between the cable engagement surface and the cable to align the first and second solid contact portions with the contact elements and cable conductors, respectively, and to preselect one or more busbar portions. and interconnect the individual contact elements of the flat cable connector with selected cable conductors.

The contact elements of the flat cable connector include tabs having a surface with a protruding knife edge capable of penetrating the conductor insulation of the cable to make an electrical connection with the connector. The first contact portion may be a tab with a recess complementary to the knife and the second contact portion may be a tab with an insulation piercing knife.

As a more specific and convenient form, the contacts 1 and 6 are integrally formed with a bus bar gripping means which is integrally connected to the contact part through the main body part, and the main body part is inserted into the through socket. The busbar receiver, which is inserted into the groove and has a busbar gripping portion on one side, is inserted into the groove and the contact portion is housed on the opposite side.

This facilitates the realization of a compact and stable structure that can be easily assembled into multiple combinations.

The kit may be particularly designed to connect the contact elements of a connector configured for a single-phase wiring array to preselected conductors of a three-phase wiring array. In this case, three inner contact portion arrangement means are provided laterally spaced apart and each sharing a through socket.
1. Separately, two second contact portion placement means are provided which are laterally separated to the outside of the surface of the second contact portion placement means and share a through socket with the motherboard grip portion placement means on the first surface; The bus bar holder has a groove extending between the distal and adjacent first contact portion locating means and the bus bar gripping portion locating means, respectively, and the third bus bar holder has a groove extending between the distal and adjacent first contact portion locating means and the bus bar gripping portion locating means. and the central first contact portion placement means.

In order to simplify the structure and maintain main strength, the third groove shares a portion with the adjacent groove.

The first contact part is formed with a busbar strip of sufficient length to serve as a predecessor of any busbar part, and the busbar gripping part is formed at right angles to the main part, and at the free end, the busbar holder is folded to be inserted into the groove. The tab preferably includes a tab having spaced apart generatrix gripping fingers.

The excess length of the generatrix section can be quickly removed in the field, and the generatrix section can be bent to the desired shape. Each contactor part and the bus bar gripping part can be stamped and molded from the same size material to minimize the cost of the dropping device, and small structural differences can be easily handled by replacing the die insert. I can do it.
