  • Connector method for manufacturing such a connector and contact element for a connector
  • the invention relates to a connector, comprising a housing and a plurality of contact elements mounted in the housing, said housing having surfaces with grooves, wherein each contact element has a contacting portion received with play in a corresponding groove and a mounting portion fixed in the housing, to a method for manufacturing such a connector, and to a contact element for a connector.
  • Connectors of this type are known in various embodiments. In view of component cost and utilization of cabinet space in combination with a growing requirement for a high-density, high-speed connector, there is a growing need to miniaturize the connector. A constraint in miniaturizing a connector is the requirement for improved signal integrity in combination with increased signal clock speed.
  • US-A-4 734 060 discloses a connector and method of the above-mentioned type, wherein the contact elements are partially accommodated in cavities of the housing aligned with the grooves and partially in the grooves, wherein the retention of the contact elements occurs in the passages, where the contact elements are fully surrounded by plastic material .
  • the mounting of the contact elements requires an axial insertion of the contact elements, wherein a significant axial length of the contact element has to pass through the cavity.
  • the contact ele- ments in both the male and female connectors have a longitudinal tapering in cross-section with a thickened contacting dome at their free end.
  • This shape of the contact elements entails drawbacks in terms of manufacturing and results moreover in internal stress.
  • suffi- cient space must be available within the connectors for the contact elements to deflect along a distance corresponding to twice the dimension of the thickened part.
  • the design of this connector imposes limitations regarding miniaturizing and manufacturing the connector.
  • the invention aims to provide an improved connector and improved method of manufacturing the same.

  • the invention also provides an improved method for manufacturing the connector, wherein a housing part is provided, said housing part having an elon- gated mainly rectangular flat shape and a series of open grooves in one of the main surfaces, said grooves extending transverse to the longitudinal direction of the housing part along the full transverse dimension of the main surface, wherein the contact elements are made as single beam contacts and are inserted into said grooves in a direction perpendicular to the main surface of the housing part.
  • manufacturing requires insertion along a very short distance only, wherein mutual contact between the housing and plated areas of the contact elements is fully avoided.
  • a plurality of interconnected contact elements is provided, wherein the interconnected contact elements are inserted into the grooves of a housing part in one step.
  • the connector design of the invention allows to provide any number of rows without tooling-up a new housing mould, resulting in a flexible and low cost manufacturing.
  • each module is provided with flat end surfaces, wherein the distance between the first and last contact elements of a row of contact elements and the end surfaces is such that with two modules stacked in row direction the pitch of adjacent con- tact elements of stacked modules equals an integer times the pitch between successive contact elements in row direction.
  • the pitch of adjacent con- tact elements of stacked modules equals an integer times the pitch between successive contact elements in row direction.
  • the transverse dimension of one module equals twice the pitch between successive contact elements in row direction.
  • the number of contact elements per unit of length is the same in row and column direction.
  • the connector comprises a number of assembled com- ponents, wherein the mounting frame provides a mutual positioning and interconnection of the components.
  • Right-angled and straight embodiments can be manufactured using the same front housing sections and mounting frame.
  • the metal mounting frame is provided with location projections for mounting the connector on a printed circuit board.
  • the metal mounting frame is adapted to provide at least a strong mechanical connection to the printed circuit board so that the contact elements can be provided with terminals optimized for a surface mount connection.
  • the location projections of the mounting frame are made as contact sections for connecting the mounting frame to a ground of a printed circuit board.
  • the mounting frame provides for a connection of the ground of the connector to the ground of the printed circuit board.
  • the housing is an assembly modules with two identical joined housing parts, so that any waviness or curvature of the housing parts will be mutually compensated resulting in a flat module with accurate shape and dimensions.
