Abstract

An electric connector makes it possible to achieve downsizing excellently to improve electric connection reliability by preventing deformation when fitting to a mating connector. An engaging projection projecting is provided on an opening end edge of either an insulating housing or a conductive shell. An engaging hole into which the engaging projection is inserted is provided on the other opening end edge. The insulating housing and the conductive shell are fixed to each other in a direction orthogonal to the fitting direction by inserting the engaging projection into the engaging hole so that rigidity is largely increased. The fixation mechanism of the insulating housing and the conductive shell do not project inside the insulating housing so that it is possible to reduce the height and make pitches narrow.

Claims

1. An electric connector which is configured such that a mating connector is appropriately inserted in a fitting direction through an inside of an opening for fitting formed in an insulating housing of the electric connector, comprising:

an opening end edge of a conductive shell covering the insulating housing from outside thereof is disposed to extend along an outer surface of an opening end edge forming the opening for fitting of the insulating housing, wherein,

an engaging projection projecting along a fitting direction used with the mating connector is provided at one of the opening end edges of the insulating housing and the conductive shell,

an engaging hole, into which the engaging projection is inserted in the fitting direction, is provided on the other of the opening end edges of the insulating housing and the conductive shell, and

the engaging projection is inserted into the engaging hole without projection from the outer surface of the conductive shell so that the insulating housing and the conductive shell are fixed to each other in a direction orthogonal to the fitting direction used with the mating connector, whereby

both the opening end edges are disposed at approximately the same position as in a fitting direction of both the connectors.

2. The electric connector according to claim 1, wherein,

the engaging projection is formed at the opening end edge forming the opening for fitting of the insulating housing, and

the engaging hole is formed at the opening end edge of the conductive shell.

3. The electric connector according to claim 1, wherein,

the electric connector is configured such that a conductive shell of the mating connector is able to come into contact with an outer surface of the opening end edge of the conductive shell when the mating connector is fitted, and

the conductive shells of both the connectors become disposed in a stacking manner in the direction orthogonal to the fitting direction.

4. The electric connector according to claim 3, wherein,

the electric connector is configured such that both the opening end edges of the insulating housing and the conductive shell fixed to each other in the direction orthogonal to the fitting direction become sandwiched between the conductive shell and the insulating housing of the mating connector.

5. The electric connector according to claim 4, wherein,

the electric connector is configured such that a front end projection of the mating connector is inserted into the inside of the electric connector through the opening for fitting formed in the insulating housing, and

the front end projection of the mating connector comes into pressure-contact with a contact point of a conductive contact disposed in the insulating housing in the direction orthogonal to the fitting direction, which results in displacement of the conductive contact, so that both the opening end edges of the insulating housing and the conductive shell are forced to expand in a pressing manner according to the displacement of the conductive contact.

6. The electric connector according to claim 5, wherein,

the electric connector is configured such that the conductive contact is mounted in a cantilever manner having the contact point at a free end of the conductive contact.
