- Connectors of the above type are known, which comprise an insulating enclosure defining a number of cavities having respective axes parallel to the connection direction of the connector to a complementary connector, and for housing the terminals, which are retained inside the cavities by primary retaining means.
- Such connectors also comprise a secondary retaining device for determining correct insertion and further ensuring retention of the terminals inside the respective cavities.
- The device normally comprises a movable plate fittable in a closed position to the front of the enclosure in said connection direction, and having a number of through seats engaged in sliding manner by respective contact portions of the terminals, which project from the plate in said closed position.
- The movable plate can only be fitted to the enclosure when all the terminals are correctly inserted and retained inside the respective cavities by the primary retaining means, which are normally defined by an elastically deformable lance forming part of the enclosure. In the event of incorrect or incomplete insertion of any one of the terminals, the primary retaining means remain deformed, thus preventing assembly of the movable plate and enabling detection of the fault.
- Known connectors of the type briefly described above have several drawbacks.
- In particular, when connecting such connectors to complementary connectors, the contact portions of the male terminals, which, as commonly known, are fairly long, may be deformed accidentally, thus possibly resulting in impaired efficiency.
- Moreover, the contact portions of the male terminals are often housed inside a hollow front portion of the enclosure, which is a possible receptacle for dust and dirt, which may impair electrical contact between the male and corresponding female terminals.
- It is an object of the present invention to provide an electric connector designed to eliminate in a straightforward, reliable manner the aforementioned drawbacks typically associated with known connectors.
- According to the present invention, there is provided an electric connector comprising:
- an insulating enclosure defining a number of cavities for housing respective male electric terminals and having respective axes parallel to a connection direction of said connector to a complementary connector;
- primary retaining means for retaining said terminals inside the respective said cavities and preventing withdrawal of the terminals; and
- secondary retaining means comprising at least a
first member, which mates with said enclosure, in said
connection direction, in a closed position, and
cooperates in said closed position with said primary
retaining means to determine correct engagement and
prevent release of said terminals by the primary
retaining means; said first member having a number of
through first seats engaged in sliding manner by
respective contact portions of said terminals;
characterized in that said secondary retaining means comprise a second member having a number of through second seats for respective said contact portions of said terminals; and connecting means for connecting said first and second members facing each other and in such a manner as to move, with respect to each other and in said connection direction, between a first work configuration in which said first and second members are positioned parallel and a given distance apart, and a second work configuration in which said first and second members are gripped together by the thrust exerted by said complementary connector engaging said connector. - A preferred, non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:
- Figure 1 shows a view in perspective of an electric connector in accordance with the present invention;
- Figure 2 shows a larger-scale longitudinal section of the Figure 1 connector connected to a complementary connector;

Connector 1 is assembled as described below, commencing from an initial condition in whichplates device 30, in the first work configuration, are housed insiderecess 16 ofenclosure 3 in the preassembly position, andterminals 5 are housed insiderespective cavities 4. - If one of
terminals 5 is not correctly inserted insiderespective cavity 4, thecorresponding lance 26 remains deformed and prevents thecorresponding wedge 40 ofplate 31 from being inserted fully insidecavity 4 betweenlance 26 andwall 27, thus preventingdevice 30 from being set to the full-assembly position, and connection ofconnector 1 and complementary connector 1'. - Conversely, if
terminals 5 are all correctly engaged byrespective lances 26,wedges 40 ofplate 31 may all be moved into the closed position anddevice 30 into the full-assembly position, thus enabling connection ofconnector 1 and complementary connector 1'. - More specifically as portion 16' of connector 1' is inserted inside
recess 16 ofconnector 1, portion 16' pushes andgrips plate 42 toplate 31 in direction A, thus flexingblades 52. At the same time, female terminals 5' of connector 1' mate withcontact portions 22 of respectivemale terminals 5, which are maintained in the correct connection position by being supported by bothplates - The second work configuration of
plates connectors 1 and 1'. - The advantages of
connector 1 according to the present invention will be clear from the foregoing description. - In particular,
plate 42 defines an additional front support forcontact portions 22 ofterminals 5 during connection to corresponding female terminals 5' of connector 1', thus preventing accidental deformation ofcontact portions 22, and is gripped toplate 31, i.e. constitutes no noticeable increase in overall size, in the lock position ofconnectors 1, 1', i.e. when said supporting action is no longer required. - Moreover, in the full-assembly position of
plates plate 42 "closes" the front ofrecess 16 to keep out dust and dirt. - Clearly, changes may be made to
connector 1 without, however, departing from the scope of the present invention.
