Abstract

A method for combining a fluid filter (46) to a tubing quick connector (24) includes the use of a metal cap (32) welded to an outer peripheral surface (36) of the quick connector housing (25). The cap is also welded at an outer peripheral surface (38) to a metal filter body (42). This invention increases the versatility of where the various assembly operations are performed, and allows the filter manufacturer or final filter user to assemble the systems, without having to perform any assembly of the quick connector structure.

Description

CONNECTOR FOR FLUID FILTER *-*
BACKGROUND OF THE INVENTION This application relates to an improved method of connecting a tube to a filter. 5 Fluid filters are typically used to remove impurities from a fluid. In prior art high volume productio there may have been some difficulty in attaching fluid tubes to a filter. Prior art connections have often included threaded members which are relatively difficult and time 10 consuming to use.
It is known in the prior art to use tubing quick connectors which allow a tube to be snapped into the fluid connector. Tubing quick connectors have not typically been used with filters, however, since the steps involved in 15 connecting the tubing quick connector to the filter may be harmful to the tubing quick connector. For that reason, a practical combination of a metal filter and a tubing quick connector has not been provided by the prior art.
SUMMARY OF THE INVENTION
20 In a disclosed embodiment of the present invention a tubing quick connector is incorporated into a filter. A tube may then be connected into the filter quickly and reliably. Preferably, a filter cap is welded to an outer peripheral surface of a tubing quick connector housing. The
25 filter is welded to an outer peripheral surface of the cap. The cap is preferably welded to the tubing quick connector housing at a location spaced axially from any contact with a retainer and seal within the housing. In this way the ? retainer and seal are not harmed by the machine which grips
30 the quick connector housing to perform the welding operation
The cap allows the tubing quick connector to be fully assembled at a first location by the quick connector manufacturer, and then have the cap welded to the quick connector housing. Further, the use of the cap welded to t quick connector housing allows standard quick connectors to be incorporated into the filter. The quick connector manufacturer may ship the assembled cap and quick connector to a filter manufacturer, or an assembler who assembles the filters and quick connectors into a fluid system, such as on a vehicle. In this way, the end users such as the vehicle assembler or filter manufacturers need not assemble the quick connectors.
In a method according to the present invention, the quick connector is initially assembled and the cap is then welded to an outer peripheral surface of the quick connector housing. The filter is then welded to the outer peripheral surface of the cap. It is ensured that the quick connector structure is not harmed within its housing by welding the cap or filter.
These and other features of the present invention can be best understood from the following specification and drawings, of which the following is a brief description.
BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a cross-sectional view through a filte incorporating a quick connector according to the present invention.
Figure 2 is an end view of the structure illustrated in Figure 1. Figure 3 is a cross-sectional view through a quick connector and cap according to the present invention.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
A metal filter 20 is shown in Figure 1 having a supply tube 22 connected through a tubing quick connector 24. Quick connector 24 incorporates housing 25, which is preferably metal. Housing 25 has a seal package 26 at an axially inner position and a retainer 28 at an axially outer position. Retainer 28 may be generally of the type commonly known for retaining a tube 22 within housing 25. As shown, tube 22 may have an upset portion 30 which is positioned axially inwardly of legs 31 from retainer 28 to retain tube 22 within housing 25. A filter cap 32 has a radially inner edge 34 welded at 36 to the outer peripheral surface of housing 25. As shown, retainer 28 has a radially outermost ϋ portion extending to a position adjacent an inner peripheral
5 surface' of housing 25 at a location 37 axially spaced from weld location 36. When weld 36 is formed, a machine will typically grip inner peripheral edge 34 of cap 32 and housi 25 adjacent weld joint 36. Due to the spaced relationship o retainer contact point 37 and weld point 36, no damaging 10 force is transmitted through the wall of housing 25 to retainer 28 during welding.
Cap 32 has an outer peripheral surface 38 which is welded at 40 to a metal filter body 42. Metal filter body 4 is also connected to a male end 44 which is connected to a 15 fluid conduit leading from filter body 42.
A filter element 46 is positioned within metal bo 42. Fluid enters filter body 42 through tube 22, is filter within filter element 46, and is then led outwardly through male end 44. 20 As shown in Figure 2, retainer 28 has a plurality of legs 31 each having bumps 50 which provide resistance to entry of upset portion 30 axially beyond legs 31. When it desired to insert tube 22 into connector housing 25, upset portion 30 is moved inwardly until it abuts bumps 50. At 25 that point, a significantly increased force is required to move tube 22 further axially inwardly. Once this increased force is met, tube 22 forces legs 31 to flex radially outwardly. Upset portion 30 then moves quickly beyond bump 50 and legs 31 then flex back into the fully assembled 30 position illustrated in Figure 1.
As shown in Figure 3, legs 31 extend axially and radially inwardly. Other than bumps 50, retainer 28 is as "* generally known in the prior art.
As also shown, point 37 and seal package 26 are 35 axially spaced from weld point 36. Cap 32 is shown having cylindrical ditch 52.
In a method according to this invention, retainer 28 and seal package 26 are positioned within housing 25. A inner peripheral portion of cap 32 is welded to housing 25 at point 36. A gripper member grips cap 32 and housing 25 at axial positions adjacent both sides of point 36. Filter body 42 is then welded to cap 32. Laser, electron beam welding and other known welding techniques are envisioned within this invention.
In a preferred embodiment of the present invention, outer housing 25, metal filter body 42, and cap 32 are all formed of stainless steel. The other portions of the inventive structure are formed of known materials commonly used for the particular portion.
A preferred embodiment of the present invention has been disclosed, however, a worker of ordinary skill in the art would recognize that certain modifications would come within the scope of this invention. For that reason, the following claims should be studied in order to determine the true scope and content of this invention.
