Abstract

Electrical connection (11) composed of a connector (12) and an opposing connector (13). The connection allows guaranteed electrical contact even in poor conditions. The connector (12) has chambers (16) in a contact carrier (14) with fixed contact elements (23). Each element (23) can be coupled to an opposing contact element (28) which is introduced into the respective chamber (16) and is guided therein practically without play. Each chamber (16) can deform inside the holder. contacts (14) to compensate for the positional tolerances between the contact elements (23, 28).

Description

STATE OF THE ART The present invention relates to a connection

  electric comprising a connector removably coupled

  ble to an opposite connector comprising a contact support of the connector made of electrically insulating plastic, forming at least one receiving chamber housing a

  contact which, when the connection is closed, is electrically connected

  tracing to an opposite contact element of the oppo- connector

se.

  We know of such a connection between a connec-

  tor and an opposite connector according to document DE-41 18 696-

  A1. The connector comprises at least one contact element housed in a chamber of a contact support of the connector; this contact element is coupled to an element of

  opposite connector contact to make the electrical connection

  stick. The accelerations exerted on the connections, for example the jolting movements of the operation of a diesel engine, mean that when a connection is closed between a contact element and the opposite contact element, put in

  contact by force bond, there are relative movements

  tifs occasioned by the play of the movement of the con-

  tact in the accommodation. As a result, the contact surfaces of the contact element and of the opposite, fixed contact element can wear out and the contact will be less

  good because provided by the support material providing a

  less good tact or, due to corrosion by rubbing

  which could jeopardize contact security

of the connection.

  Advantages of the invention The object of the present invention is to remedy these drawbacks and to this end relates to a connection of the type defined above, characterized in that the receiving chamber is housed in a deformable manner in the support of

  contacts by at least one flexible connecting element, the cham-

  bre receiving the contact element in a fixed manner and guiding

  practically without play the opposite contact element.

  Thus, the invention makes it possible to remedy the inconveniences

  come and make a particularly secure connection.

  Advantageously, the contact element is

  fixedly housed in the room to avoid movement

  relative elements between the contact element and the chamber. To nevertheless avoid mechanical tension between

  the contact element and the opposite element because of the tolerances

  those of reciprocal position, and thus insufficient contact,

  the chamber which guides the connection element practically without play

  opposite tact which penetrates there, is mounted so as to be able to shift or move in the contact support; thus, the contact element and the opposite contact element can function properly and be guided jointly by the

  bedroom. This provides the basis for a guaranteed contact of the cons

nexion.

  According to other advantageous features of the invention: - the reception chamber is mounted via

  two opposite rib-shaped connecting elements,

  each linked on the one hand to a longitudinal wall of the chamber and on the other hand, to a boundary wall of the contact support and pressing against a longitudinal wall of an adjacent chamber or against the longitudinal walls of adjacent chambers, - the chamber has a reception opening facing the opposite connector, this opening being remote from the connecting elements, and comprising an entry segment in

  funnel shape to introduce the op-

  placed and a centering segment to center this element of

opposite contact.

Drawing

  An exemplary embodiment of the invention is shown

  presented in the drawing and will be described below in more detail: The only figure is a partial sectional view of

the electrical connection.

  Description of the exemplary embodiment

  The exemplary embodiment is shown in FIG.

  gure in the form of part of a connection 11 showing a connector 12 connected to an opposite connector 13 simply sketched. Connector 12 includes contact support

  14 made of electrically insulating plastic. The sup-

  contact port 14 has a number of chambers 16 corresponding to

  corresponding to the number of poles of the connection 11; only one

  chamber is shown symmetrical about an axis lon-

  gitudinal 17 while the other rooms located in particular

  in line on it, are in the section plane.

  On the front side facing the opposite connector 13, the chamber 16 has a receiving opening 18 and opposite this, at the other end of the chamber 16,

  there is a connection opening which is no longer shown

  tee. The chamber 16 is delimited laterally by two longitudinal walls 19 aligned on the longitudinal axis 17. Each of the longitudinal walls 19 comprises substantially in the middle of its length, on the outside, a connecting element 21 in the form of a rib, which is deviates substantially at right angles. The two opposite connecting elements 21, one of which is connected to a boundary wall 22 of the contact support 14 and

  the other to the longitudinal wall 19 of a chamber 16 adjja-

  cente positions the chamber 16 in the contact support 14

  so that it can shift within the limits of the sou-

  plesse connecting elements 21 and in particular so that its

  receiving port 18 furthest from the connecting elements

its 21, can shift.

  In the case of a room 16 which is not located

  at the edge of the contact support 14, the two connecting elements

  its 21 join the longitudinal walls 19 of neighboring chambers 16.

  The chamber 16 receives in an adapted manner an element

  contact ment 23 which is only shown in a simple manner

  folded and partial; this implementation, without play, is blocked in translation. The contact element 23 comprises a contact box 24 applying against the interior face

  longitudinal walls 19; inside, the box

  wears elastic contact tabs 26.

  The elastic contact tongues 26 have parts 27 of curved shape applied one against the other with a pre-stress and capable of spreading elastically in the radial direction; the free ends of

  parts 27 deviate from each other.

  An opposite contact element 28, in the form of a

  sheet associated with the contact element 23; its free end has an insertion zone 29 whose width and thickness are decreasing; it is hooked in a manner not shown in the opposite connector 13. The connector

  opposite 13 is fixedly mounted as a knife bar on a device

control or a sensor.

  To close connection 11, engage connector

  tor 12 on the opposite connector 31 in the direction of engagement parallel to the longitudinal axis 17. The element of

  opposite contact 28 passes through the receiving hole 18 light-

  ment larger by the assembly play to arrive in the chamber 16 and thus in the contact element 23 downstream of

  the receiving orifice 18; by establishing electronic contact

  With the contact element 23, the contact element 28 spreads the ends 27 of the elastic contact tabs 26. In the event of position tolerances between the opposite contact element 28 and the contact element 23, the element 28 arrives in the receiving orifice 18 eccentrically with respect to the inlet segment 31. The funnel shape of this segment generates offset forces applied to the chamber 16 so that after the offset of this chamber 16, the opposite contact element 28 penetrates through the segment

  centering 32 central of the receiving port 28 for ve-

  center in room 16 and in the element

contact 23.

  The offset or deflection of the chamber 16 per-

  puts in place a tensionless contact between the contact element 23 and the opposite contact element 28 for a guaranteed connection which remains maintained even under

  the effect of stresses caused by tremors; Indeed-

  fet, the chamber 16, capable of being offset guides in the same direction both the opposite contact element 28 and the contact element 23 fixedly housed in the chamber 16.
