Problems solved by technology

However, the structural form of these conventional connectors is complex and prone to damage, since the first and second tongues are surrounded by radial cuts in the material at the side walls of the connector, they are only connected by a small axial web to the connector sidewall

Embodiment Construction

[0031] Figure 1A The holding device 10 is shown in a perspective side view. The shown holding device 10 is made of a plastic material, more specifically a polymer-based plastic material, more specifically obtained as a whole by injection molding or the like. The holding device 10 has an annular bottom 11 with a cylindrical outer surface and a conical funnel-shaped inner surface, which is described below. Figure 2B can best be seen in . The first and second flexure members 12 , 22 protrude axially from the annular bottom 11 . The first and second flexure members 12, 22 are alternately arranged with an axial slit 15 provided between each pair of the first and second flexure members 12, 22. Due to the slit 15 and the general properties of the plastic material, the first and second flexure members 12 , 22 have a certain elastic deformation capacity in the radial direction, ie they can be flexible in the radial direction perpendicular to the axial direction of the tubular retai...

Abstract

The invention provides a quick connector made of plastic material for forming a snap connection between a tubular male part (50) and a female part (40) of a fluid connection system. The connector has a retaining device (10) adapted to be disposed within a mouth (41) of a female part (40) and having first and second flexure members (12, 22) for snap engagement with a male part (50) and a female part (40), respectively. The first and second flexure members (12, 22) are provided at circumferentially spaced portions of the retention device (10) such that the overall axial dimension of the retention device (10) is reduced.

Description

technical field [0001] Quick connectors or snap-on connectors are widely used to provide convenience between male components (such as sleeves, sockets or fittings) and female components (especially holes in block components of fluid delivery systems). connect. Traditionally, such connectors are made of metal. They may have a threaded part to be screwed into the female part and a sleeve part that extends from the female part after the threaded part is screwed into the female part and has a yoke A resilient member in the form of a spring that exerts a spring force radially to snap into engagement with the recess of the male part. Background technique [0002] The disadvantages of conventional connectors are their heavy weight and high production costs, since they are mainly made of metal. In addition, they have a considerable axial extension and have two potential leak locations. At the threaded portion, there is a first leak location where the first O-ring forms the seal ...
