Definitions

  • An electrical connector comprising a connector block having a plurality of electrical contacts therein and having keying means for permitting stacking of the connectors without interruption of contact spacing and for preventing improper stacking of the connectors. Windows are disposed along opposite faces of the connector for facilitating removal of the contacts from the connector block.
  • This invention relates to the art of electrical connectors and, in particular, to a connector having a plurality of electrical contacts and capable of being stacked without disturbing the spacing between adjacent contacts.
  • the connector block has complementary keying means disposed in its opposite end faces which permit connector stacking but which prevent improper positioning of one connector relative to its adjacent connector. Provision is also made in the connector block for the entry of a tool to elfect removal of the electrical contacts from the connector block.
  • a further object is to provide a connector having means to permit withdrawal of the electrical contacts from the connector block.
  • a further object is to provide an electrical connector of simple and inexpensive construction and wherein the connector block may be conveniently formed as a onepiece molded part.
  • FIG. 1 is an overall perspective view showing a preferred form of electrical connector made in accordance with the teachings of this invention
  • FIG. 2 is a fragmentary perspective view of one end of the connector as seen looking generally in the direction of the arrow 2 of FIG. 1;
  • FIG. 3 is a cross-sectional view taken along the line 3--3 of FIG. 1;
  • FIG. 4 is a cross-sectional view taken along the line 44 of FIG. 3;
  • FIG. 5 is a front elevational view showing the method of stacking the connector of FIG. 1.
  • FIG. 1 there is shown an electrical connector indicated generally at 10 and comprises a connector block 12 formed of a suitable dielectric material such as diallyl phthalate.
  • the block 12 has a plurality of regularly spaced apertures 14 extending therethrough, said apertures being disposed generally along two parallel rows.
  • the forward end of the aperatures are beveled as at 16 to assist in entry of a mating electrical connector.
  • each of the apertures 14 Located within each of the apertures 14 is an electrical contact indicated generally at 18 (see FIG. 3).
  • Various electrical contacts may be used without departing from the scope of this invention.
  • the contact 18 is crimped or otherwise secured at its rearward end to conductor means 20 in a conventional manner. Forward movement of the contacts within the apertures 14 is limited by shoulder means 22 located at the forward end of the apertures and positioned to engage the forward end of the contacts.
  • Each of the contacts 18 is provided with a resilient lance 24 struck from the contact body along one side thereof.
  • the connector block 12 is provided with a series of Windows 26 disposed along the upper face of the block and a series of windows 28 disposed along the lower face of the block.
  • Each of the windows 26 and 28 intersect one of the apertures 14 and are positioned to receive the lances 24 of the contacts. The lances will move into the space provided by the windows during insertion of the contacts and these lances will prevent withdrawal of the contacts from the block or housing 12.
  • the windows 26 and 28 also provide means by which a tool such as indicated at 30 in FIG. 3 may be inserted to engage the lances of the contacts to thereby depress the lances and permit withdrawal of the contacts from the connector block.
  • the tool 30 may be of any suitable configuration to eifect this function.
  • the lances 24 of the electrical contacts are not centrally located along the contact edge as set forth more fully in the above mentioned patent and, therefore, the windows 26 and 28 are olfset with respect to each other so that each row of windows is aligned with the lances of the two rows of contacts.
  • the connector block 12 is of rather simple construction and, therefore, may be conveniently formed as a molded part thereby reducing the manufacturing costs of the connector.
  • the connectors must be sufiicient- 1y versatile to permit their use in many various systems. The requirements of particular uses will vary with regard to the number of electrical contacts which are necessary and, therefore, most connector blocks must be available in various lengths and separate molds must be provided for each of these lengths.
  • the connector block of the instant invention is designed with a relatively small number of contact apertures but the block is capable of being stacked with adjacent blocks to provide the required versatility to the connector. This is accomplished by a keying means to be now described.
  • the connector block 12 has opposite end faces 32 and 34 between which the apertures are disposed.
  • the end face 32 has a keying means 36 integrally formed therein and comprises a male portion 38 and a female portion 40.
  • the portion 38 consists of an elongated cylindrical member which extends generally parallel to the apertures 14.
  • the portion 40 consists of a recess formed within the face 32 and of a shape generally complementary to the portion 38.
  • the portion 38 is of slightly smaller longitudinal extent than the portion 40;
  • the opposite end face 34 is similarly provided with a cylindrical portion 42 and a recessed portion 44 although the relative position of these potrions is opposite to that of face 3 2.
  • a plurality of connectors 10 may be stacked in sideby-side relation such as shown in FIG. thereby providing connectors having varying numbers of contact positions for use in various electrical systems.
  • the spacing between contacts remain constant throughout the entire length of the connector.
  • the keying means 36 of this invention permits such uniformity of spacing because of its complementary configuration.
  • the end walls 46 of the connector blocks are one half the width of the remaining walls 48 of the connector block disposed between each of the contact apertures. Therefore, when the connectors are stacked in end-to-end relation the two end wall thicknesses will be equal to the remaining wall thicknesses and the contact spacing will be uniform.
  • a connector block for receiving electrical contacts said block being formed of a dielectric material and comprising a plurality of contact-receiving apertures regularly spaced along said block, a pair of end faces disposed on opposite ends of said block, said apertures being located between said end faces, and keying means located in said end faces, the keying means on one end face being complementary to the keying means on the opposite end face whereby a plurality of said connector blocks may be stacked in end-to-end relation, said keying means on each said end face comprising a male portion and a complementary female portion, said male and female portions being adjacent each other and collinear.
  • a connector block as set forth in claim 2 further comprising window means disposed along top and bottom faces of said block and intersecting said contact receiving apertures for facilitating contact removal.
  • An electrical connector comprising a connector block formed of a dielectric material, a plurality of contact-receiving apertures regularly spaced along said block, a plurality of electrical contacts disposed respectively in said apertures, conductor means extending from each said contact, lance means for securing said contacts within said connector block, a pair of end faces disposed on opposite ends of said block, and keying means located on said end faces, the keying means on one end face being complementary to the keying means on the opposite end face of said block whereby a plurality of said electrical connectors may be stacked in end-toend relation, said keying means on each said end face comprising a male portion and a complementary female portion, said male and female portions being adjacent each other end collinear.
  • An electrical connctor as set forth in claim 7 further comprising window means disposed along top and bottom faces of said block for cooperating with said lance means.
