Abstract
Abstract A component protective system is disclosed for an electrical component which can be soldered in a printed circuit board by means of a solder bath. A portion of the components which projects through the printed board is protected from the influence of the solder bath by use of a protective collar arranged around the portion to be protected. The protective collar is open in a direction toward the solder bath and projects beyond the portion to be protected. Upon immersion of the component together with the printed circuit board into a solder bath, an air cushion is formed within the protective collar. This air cushion prevents contact between the solder and the portion to be protected and forms a heat insulator which protects this portion from heat damage.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
87 words
A component protective system, comprising: an electronic component designed for soldering into a printed circuit board by means of a solder bath; a portion of the component projecting through the printed board when the component is mounted; and means for protecting said portion from the influence of the solder bath, said means including a protective collar arranged on the component around the portion to be protected, and said protective collar being open in a direction toward the solder bath and projecting beyond the portion to be protected.
Claim 2
Dependent Claim
87 words
A component protective system, comprising: an electronic component designed for soldering into a printed circuit board by means of a solder bath; a portion of the component projecting through the printed board when the component is mounted; and means for protecting said portion from the influence of the solder bath, said means including a protective collar arranged on the component around the portion to be protected, and said protective collar being open in a direction toward the solder bath and projecting beyond the portion to be protected.
Claim 3
Dependent Claim
24 words
A component protective system according to claim 1 wherein the protective collar is annularly arranged on the component around the portion to be protected.
Claim 4
Dependent Claim
20 words
A component protective system according to claim 1 wherein the protective collar comprises a synthetic material molded onto the component.
Claim 5
Dependent Claim
18 words
A component protective system according to claim 1 wherein the protective collar is permanently connected to the component.
Claim 6
Dependent Claim
23 words
A component protective system according to claim 1 wherein the component comprises a key of a keyboard with a low overall relative height.
Claim 7
Dependent Claim
23 words
A system according to claim 5 wherein said portion to be protected comprises a guide for receiving a sliding portion of the key.
Claim 8
Dependent Claim
111 words
A component protective system, comprising: an electric component designed for soldering into a printed circuit board by means of a solder bath; a portion of the component projecting through an aperture in the printed circuit board when the component is mounted; means for protecting said portion from the influence of the solder bath; and said means comprising a protective collar on the component and surrounding said portion to be protected, said collar being opened in a direction toward the solder bath and extending beyond the portion to be protected so as to create a chamber filled with air which substantially prevents entry of hot vapors and solder from the solder bath.
Claim 9
Dependent Claim
111 words
