Abstract
Abstract A combined metal and plastic standoff for supporting a circuit board in fixed spatial relationship with another element comprises a rigid plastic body of appreciable length to produce the standoff effect and a metal retaining member integrally mounted on the plastic body at an operative end thereof. The metal retaining member has main and retaining portions, the main portion being fixedly disposed within the plastic body and the retaining portion extending outwardly from the plastic body having a resilient reverse bend segment, and being adapted for engagement with the circuit board or other element by an essentially longitudinal motion of the standoff along the axis of the body length to physically secure the circuit board or other element to the plastic body adjacent to the operative end.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
138 words
A combined metal and plastic standoff for supporting a circuit board in fixed spatial relationship with another element, comprising a rigid plastic body of appreciable length to produce the standoff effect, and a metal retaining member integrally mounted on said plastic body at an operative end thereof and having main, reverse bend and retaining portions, said main portion being in part fixedly disposed within said plastic body, said reverse bend portion being resilient and connecting said main and retaining portions, and said retaining portion being disposed outwardly of and longitudinally beyond said plastic body and comprising means for engagement with the circuit board or other element by an essentially longitudinal motion of the standoff along the axis of said body length to physically lock the circuit board or other element to said plastic body adjacent said operative end.
Claim 2
Dependent Claim
138 words
A combined metal and plastic standoff for supporting a circuit board in fixed spatial relationship with another element, comprising a rigid plastic body of appreciable length to produce the standoff effect, and a metal retaining member integrally mounted on said plastic body at an operative end thereof and having main, reverse bend and retaining portions, said main portion being in part fixedly disposed within said plastic body, said reverse bend portion being resilient and connecting said main and retaining portions, and said retaining portion being disposed outwardly of and longitudinally beyond said plastic body and comprising means for engagement with the circuit board or other element by an essentially longitudinal motion of the standoff along the axis of said body length to physically lock the circuit board or other element to said plastic body adjacent said operative end.
Claim 3
Dependent Claim
86 words
The standoff of claim 1 wherein said plastic body has two operative ends and a metal retaining member integrally mounted on said plastic body at each of said operative ends, said metal retaining member at one of said operative ends comprising means to physically lock the circuit board to said plastic body adjacent said one operative end and said metal retaining member at the other of said operative ends comprising means to physically lock the other element to said plastic body adjacent said other operative end.
Claim 4
Dependent Claim
16 words
The standoff of claim 1 wherein the other end of said plastic body defines a recess.
Claim 5
Dependent Claim
11 words
The standoff of claim 3 wherein said recess is internally threaded.
Claim 6
Dependent Claim
15 words
The standoff of claim 1 wherein the other end of said plastic body is solid.
Claim 7
Dependent Claim
31 words
The standoff of claim 1 further comprising a spring member mounted at said operative end and configured and dimensioned to hold the circuit board or other element against said retaining member.
Claim 8
Dependent Claim
16 words
The standoff of claim 1 wherein said plastic body is formed of an electrically insulative plastic.
Claim 9
Dependent Claim
16 words
The standoff of claim 1 wherein said plastic body is formed of an electrically conductive plastic.
Claim 10
Dependent Claim
18 words
The standoff of claim 1 wherein said metal retaining member is resilient and is formed in one piece.
Claim 11
Dependent Claim
37 words
The standoff of claim 1 wherein said retaining member comprises a pair of said retaining portions, each of said retaining portions being connected to a different end of said main portion by a different reverse bend portion.
Claim 12
Dependent Claim
31 words
The standoff of claim 10 further comprising a spring member mounted at said operative end and configured and dimensioned to hold the circuit board or other element against said retaining portions.
Claim 13
Dependent Claim
25 words
The standoff of claim 1 wherein said retaining portion snaps in by a movement having a component perpendicular to the axis of said body length.
