ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention concerns a device for perpendicular connection between two elements, as well as the tight connector and the double locking obtained.
In the connector field, and more particularly in the automobile field, connection devices have been sought that permit establishing reliable electrical connections, at the lowest cost, and which are demountable, generally one of the parts being part of a fixed network and the other able to be removed in order to be replaced.
Additional constraints are numerous, since it is necessary that such connection devices support vibrations without losing the contact pressure that assures electrical continuity, that they are mounted easily without errors being able to occur during positioning, that they are tight and that they are mechanically locked with great reliability.
Moreover, it is noted that these connection devices are frequently situated in difficultly accessible places, which requires the designer to create particular connection configurations.
Therefore, in the case where the parts to be connected are arranged along perpendicular planes, difficulty is increased by the respective movements of the two elements during vibrations or shocks, since the courses and directions of the forces to which they are subjected are often complex, even opposed.
The connection device must preferably be tightly sealed when it is used in an automobile engine compartment and preferably comprise a double locking to assure holding in position, even under extreme conditions.
SUMMARY OF THE INVENTION
The present invention seeks to alleviate these disadvantages, and the connection device according to the invention is reliable, has a manufacturing cost compatible particularly with the prices of furnishings for the automobile market, [and] an easy and rapid mounting without possibility of error during said mounting. This device also assures a reliable mechanical connection and an easy demounting.
According to the invention, the electrical connection device with perpendicular interlocking of a male part comprising at least one electrical connection contact with elastic blades forming a clamp, arranged in a contact-bearing casing with a female part comprising at least one contact in the form of a blade, borne by a base, said elastic blades forming a clamp with the contact or contacts coming to be positioned on both sides of the thickness of the corresponding contact blade of the female part.
BRIEF DESCRIPTION OF THE DRAWINGS
More particularly, the contact or contacts are made up of a bare zone of a metal strip elongated in a direction perpendicular to the axis of interlocking of the male part into the female part. This metal strip for the contact or contacts is Inserted into an insulating base which has been molded, the bare zone corresponding to an empty space in said molding.
More specifically, the device comprises at least two metal strips, these two juxtaposed metal strips being separated from each other by an insulating partition molded with the insulating base.
According to another characteristic, each blade of the contact or contacts of the female part comprises a contact surface defined by two transversal folds that permit an off-setting of said surface with regard to the longitudinal axis of the base.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The contact-bearing casing comprises the first and second locking means of the female contact or contacts onto each corresponding blade.
The invention also has for a subject the corresponding electrical connector, with perpendicular interlocking, which comprises a matrix in which the base and contact assembly of the female part is integrated, said matrix being provided with a housing of conjugate profile to the head of the casing bearing the contacts and sealing means.
Joints assure the tight seal of the assembly after interlocking.
Moreover, means for clamping the male and female parts secure the joining.
