Abstract
A device for connection between a first piece and a second piece including: a male part and a female part, the male part being intended to be inserted in the female part along the first direction, the male part including a snapping-on portion and a guide portion downstream of the snapping-on part in the direction of insertion of the male part in the female part, the female part including a snapping-on portion and a guide portion downstream of the snapping-on part, the male part and the female par being such that the guide portions provide guidance in the first direction of the male part before the snapping-on portions cooperate with each other.
Claims18
A device for connection between a first piece and a second piece intended to be stressed in a first direction, including:
- a male part intended to be secured to the first piece and a female part intended to be secured to the second piece, the male part being intended to be inserted in the female part along the first direction,
- the male part including at least one first guide portion and a first snapping-on portion, the first guide portion being disposed downstream of the first snapping-on portion in the direction of insertion of the male part in the female part,
- the female part including a second guide portion and a second snapping-on portion, the second guide portion being disposed downstream of the second snapping-on portion in the direction of insertion of the male part in the female part,
- the male part and the female part being configured so that the first and second guide portions cooperate with each other and provide guidance in the first direction of the male part before the first and second snapping-on portions cooperate with each other,
- wherein the male part and the female part are manufactured from the same material.
A hydraulic 3/2 control valve, including an electromagnetic actuator, a first piston cooperating with a piston seat, at least one device for connection between the first piston and a rod secured to the core at least in the first direction, and a second piston secured to the first piston in the first direction, the first piston and the second piston being aligned in the first direction, the at least one device including:
- a male part intended to be secured to the first piece and a female part intended to be secured to the second piece, the male part being intended to be inserted in the female part along the first direction,
- the male part including at least one first guide portion and a first snapping-on portion, the first guide portion being disposed downstream of the first snapping-on portion in the direction of insertion of the male part in the female part,
- the female part including a second guide portion and a second snapping-on portion, the second guide portion being disposed downstream of the second snapping-on portion in the direction of insertion of the male part in the female part,
- the male part and the female part being configured so that the first and second guide portions cooperate with each other and provide guidance in the first direction of the male part before the first and second snapping-on portions cooperate with each other.
