Definitions
- the subject of the present invention is a connector plug-in according to the preamble of claim 1.
- the boxes are generally made up of plastic molded in one piece. During the molding, we generally clean in the passage of the legs projecting elastics, intended to retain the contacts.
- the enclosures can be completed with a front plate guide of the respective contacts and a back plate of maintenance of a grommet in elastomeric material.
- Gasket annular clamped between the coupling part of the first case and the end part of the second case makes the waterproof connector when assembled. This annular seal is usually a lip seal.
- the present invention aims in particular to provide a connector of the above type defined responding better than those previously known to the requirements of the practice, in particular in that it reduces the insertion effort while maintaining relative guidance satisfactory of the two housings during the coupling.
- the coupling part of the first housing advantageously comprises, in front of the joint, means for sliding keying cooperating with the wall of the cavity receiving the second box.
- keying means sliding can be formed by ribs intended to engage in axial grooves formed in the wall of the cavity, beyond the shoulder.
- the skirt may include a radially offset central part, constituting a channel through which the elastic arm can be located approximately at the same axial location as the joint.
- the connector which will now be described as example has rectangular boxes and it's intended to ensure the junction between two contacts only.
- the invention is not limited to this particular case and could in particular be applied to a connector having a cable with more than two electrical contacts.
- the connector comprises a first housing 10, intended for receive female electrical contact terminals 12, from genre commonly called "clip" and a second box 14 intended to receive contact terminals 16 of blade type.
- the housings are made of insulating material, generally made of molded plastic containing reinforcing fillers.
- Contact terminals 12 and 16 can be maintained in housings in a conventional manner, for example by respective legs 18 and 20, in one piece with the case, which engage elastically in notches terminals provided for this purpose.
- the reception passage of terminals in the housing 10 is closed at the rear by a plate 22 intended to retain a grommet or "grommet" 24.
- Another plate 26 fixed in the front part of the passage is drilled with a guide hole of the blade of the male contact terminal.
- the second housing 14 includes a back plate, grommet, and through plate by the contact blade.
- the front of the first housing constitutes a coupling part, of smaller transverse dimension than the rear part.
- the back of the first case extends forward by a skirt 30 which surrounds the joint 28, but only on a fraction of its periphery (the upper fraction in Figures 1 and 3). Enter here skirt 30 and the seal 28 there remains a radial gap intended receiving a terminal portion 32 of the second housing.
- This end part 32 has an extension 34 of shape complementary to that of the skirt.
- the relative dimensions and the thickness of the terminal part 32, of the part coupling of the first housing and the skirt 30 are such that the end part engages slidingly in the skirt and in the area of the coupling part located behind the seal 28, up to a shoulder of stop.
- the joint has dimensions such that it is compressed radially during the introduction of the housing 14, then, usually by the thrust of an internal shoulder 36 of the second box.
- the locking means of a housing on the other include an elastic locking arm 38 extending forward from a root located near the back of the first box.
- This arm is in one piece with the rest of the case. It crosses a canal bounded by a projecting part 40 of the skirt 30 and ends in a hooking spout.
- This arm is intended to cooperate with a lug 42, in one piece with the second housing, having a slightly sloping front face to raise the terminal spout of the arm and an abrupt rear face intended to retain the beak after engagement.
- sliding keying means can be expected.
- they include ribs 44 projecting from the bottom and possibly the sides of the coupling part and corresponding grooves formed in the internal face of the part end of the second housing, behind the shoulder 36.
- the second housing 14 may have a terminal lug 46 which engages in a notch of corresponding shape 48 of the first housing.
