Abstract
Abstract For temporarily fixing circuit elements to a panel pins are used whose thickened inner ends are gripped by jaws behind the panel. There are sliding sleeves on the pins that may be used for pushing the gripping jaws clear of the pins so that thickened inner ends of the pins may be pulled past the jaws and the pins pulled out clear of the panel.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
271 words
A connecting device for releasably connecting a first member to a second member, comprising: a bush adapted to be fixedly secured in an opening in the first member, said bush having a central opening therethrough, having at an end nearest the second member a core portion, and having at its opposite end a further portion which has a locking jaw; a pin which is adapted to be secured to the second member, which can be axially inserted in a first direction into said opening through said bush, and which has means defining an axially facing shoulder thereon which said locking jaw can engage for releasably locking said pin against axial movement relative to said bush in a second direction opposite said first direction; a sleeve which is axially slidably supported on said pin and which, when moved axially in said first direction relative to said pin, has a first end which moves said locking jaw outwardly so as to release said pin for movement in said second direction relative to said bush, wherein said sleeve frictionally engages said pin and said core portion of said bush, the friction between said sleeve and said bush being greater than the friction between said sleeve and said pin, and an operating element which cooperates with a second end of said sleeve which is remote from said first end and projects out of said bush, said operating element being supported for movement in a direction transversely of said pin and having means for causing axial movement of said sleeve in said first direction relative to said pin in response to movement of said operating element.
Claim 2
Dependent Claim
271 words
A connecting device for releasably connecting a first member to a second member, comprising: a bush adapted to be fixedly secured in an opening in the first member, said bush having a central opening therethrough, having at an end nearest the second member a core portion, and having at its opposite end a further portion which has a locking jaw; a pin which is adapted to be secured to the second member, which can be axially inserted in a first direction into said opening through said bush, and which has means defining an axially facing shoulder thereon which said locking jaw can engage for releasably locking said pin against axial movement relative to said bush in a second direction opposite said first direction; a sleeve which is axially slidably supported on said pin and which, when moved axially in said first direction relative to said pin, has a first end which moves said locking jaw outwardly so as to release said pin for movement in said second direction relative to said bush, wherein said sleeve frictionally engages said pin and said core portion of said bush, the friction between said sleeve and said bush being greater than the friction between said sleeve and said pin, and an operating element which cooperates with a second end of said sleeve which is remote from said first end and projects out of said bush, said operating element being supported for movement in a direction transversely of said pin and having means for causing axial movement of said sleeve in said first direction relative to said pin in response to movement of said operating element.
Claim 3
Dependent Claim
48 words
The connecting device according to claim 1, wherein said bush includes a core part and a locking jaw part which respectively include said core portion and said further portion of said bush, said bush having means for connecting said core part and locking jaw part to each other.
Claim 4
Dependent Claim
36 words
The connecting device according to claim 2, wherein said core part is a soft elastic plastic with a high surface friction, and wherein said locking jaw part is one of a metal and a stiff plastic.
Claim 5
Dependent Claim
23 words
The connecting device according to claim 3, wherein said core part of said bush is polyurethane and said locking jaw part is polyamide.
Claim 6
Dependent Claim
46 words
The connecting device according to claim 2, wherein said means for connecting said core part and said locking jaw part includes a locking tooth on one of said core and locking jaw parts and a tooth pocket on the other thereof which receives said locking tooth.
Claim 7
Dependent Claim
31 words
The connecting device according to claim 1, wherein said operating element is a slide member which cooperates with a radially outwardly projecting collar provided at said second end of said sleeve.
Claim 8
Dependent Claim
49 words
The connecting device according to claim 6, wherein said slide member has a surface which cooperates with said sleeve and is inclined with respect to said pin along at least part of its length, said surface being provided on a side of said slide member which faces said sleeve.
Claim 9
Dependent Claim
51 words
The connecting device according to claim 7, wherein said surface of said slide member has a slot therein, said pin being slidably received in said slot, said slot having a width which is greater than the diameter of said pin and less than the diameter of said collar of said sleeve.
Claim 10
Dependent Claim
28 words
The connecting device according to claim 1, wherein said pin has an end which is threaded and can be screwed into a threaded opening in the second member.
Claim 11
Dependent Claim

The connecting device according to claim 1, wherein said pin has a head at one end thereof, said shoulder being provided on said head and being annular, and wherein said sleeve has an outside diameter which is at least as large as the outside diameter of said head of said pin.
Claim 14
Dependent Claim
17 words
The connecting device according to claim 1, wherein said pin has an annular recess adjacent said head.
Claim 15
Dependent Claim
174 words
The connecting device according to claim 1, wherein said bush includes a core part and a locking jaw part which are separate elements and which respectively include said core portion and said further portion of said bush; wherein said core part includes an annular lip and a plurality of angularly spaced segments extending axially away from said lip, each said segment having thereon at a location spaced axially from said lip an outwardly projecting bead; and wherein said locking jaw part includes an annular collar which snugly encircles said segments of said core part at an end thereof remote from said lip, a plurality of said locking jaws provided on said collar at angularly spaced locations and projecting axially away from said core part, and a plurality of angularly spaced teeth which project axially from said collar, which are each disposed in a space between a respective pair of said elements on said core part, and which each have a radially outwardly projecting toe in the region of said lip on said core part.
Claim 16
Dependent Claim
26 words
The connecting device according to claim 14, wherein said annular collar of said locking jaw part has a plurality of angularly spaced, axially extending cutouts therein.
